Shearing machine is a kind of equipment that can cut the metal sheet, automatically count, and send to the next process by the feeding car according to the processing requirements. It is widely used in machining. Shearing machines can cut steel plates of various thicknesses.
What are the structural characteristics of shearing machine?
How to use shearing machine?
What should be paid attention to when using shearing machine?
The frame of shearing machine adopts steel structure that has left and right vertical plates. The workbench and the blanking plate are welded into a whole structure. After welding, the internal stress is eliminated by tempering so that the shearing machine has high rigidity and stability.
The tool holder of shearing machine adopts a steel structure. Under the thrust of the cylinders on both sides, it can swing around the fixed pin to complete the shearing action without the need for a guide rail system. At the end, under the action of the return cylinder, the tool holder returns quickly and automatically. Shearing machine has a mechanism for quickly adjusting the blade gap.
The backgauge of shearing machine is installed on the tool holder and swings with it. The adjustment of the backgauge distance is driven by a motor, which is transmitted respectively to the left and right screw rods through a transmission shaft and a pair of sprocket pairs, driving the backgauge to move back and forth along the guide rod. There are two buttons to perform the forward and backward coarse adjustment. There is an adjusting hand wheel on the button box to fine-tune the stroke and positioning. A mechanical display meter displays the distance of the backgauge.
The hydraulic system of shearing machine is installed on the end face of the oil tank, which is fixed on the frame beam. It is easy to clean and disassemble. The system pressure is supplied by the oil pump.
When the material to be cut is fed, it is automatically transported in the right place of shearing machine by the motor.
The cut size of the sheet is fixed. Shearing machine controls the position to ensure the accurate cut size.
The shearing machine presses and cuts the sheet material after the material is positioned. The main motor drives the presser and the cutting tool.
The stopper allows the knife to move to a certain long position. Rotary unloading of sheet bracket.
The operation of the feeding cart includes automatic return after unloading.
The size setting, automatic counting and the number of sheets should be pre-set. The corresponding position signal detection switch must be set in the system. The installation positions of the various detection components of the shearing machine, the presser compression travel switch, the stopper fixed-length switch, the trolley status information switch, the trolley in-position switch, and the unloading in-position switch should be checked.
Shearing machine needs professors to be responsible and operate. The operator should be familiar with the structure and performance.
Shearing machine is used to cut metal plates with a thickness of 1 to 12mm. The cut sheet is based on mild steel with a tensile strength of 450N/mm² and an elongation of 25%. If you need to cut the stainless-steel plate, the cutting thickness is 1 to 6mm.
Before starting the shearing machine, check whether all parts are normal. All sundries and tools should not be stacked on the workbench.
The operator is not allowed to remove the protective fence. He must not put his hands between the upper and lower blades. The shearing machine needs to stop when picking up and cutting the workpiece to keep the movable parts at the rear of the shearing machine from injuring others.

For simple cutoff of metal parts, the shearing machine is a very tempting option, which is fast, easy and cheap. The shearing machine involves a moving blade applying pressure and pushes a workpiece up against a fixed blade.
What are the specifications you should know about the shearing machine?
How many parts does shearing machine contain?
How to install shearing machine?
When purchasing metal shearing machine, take the required dimensions fitted various workpieces into account.
Sheet thickness is the sheet or web thickness that can be sheared. Sheet length is the largest dimension of working distance from right to left that can be cut. Sheet depth is the distance from the centerline of the ram to the back frame in a gap frame.
Operating a shearing machine requires strict adherence to safety procedures. Operators can activate the shearing machine using several methods. Operators can control manually by a footswitch, pendant, or push-button. The automatic shearing machine automatically performs without intervention. The shearing machine changes tools and parameters in a pre-programmed manner, such as speed or applied load.
Shearing machines require periodic maintenance. The blade performs sharpening on a regular basis so that shears do not yield poor quality cuts. The angle of the cutting edge and the finish of the grind play important roles in affecting performance and lifespan.
The shearing machine is composed of a frame, a pressing mechanism, a blade gap adjustment device, a knife holder, and a hydraulic system.
The rack adopts a combined welding structure with good rigidity, including left and right columns, front wall panels, workbenches, and fuel tanks.
The pressing mechanism is composed of a set of material pressing feet installed at the bottom of the frame beam. After the pressurized oil gets into, the presser foot plunger presses down the steel plate. The presser foot does not reset depending on the spring force until the shearing machine stops.
The adjustment of the upper and lower cutting tool gap is realized by rotating the blade gap adjustment device handle to drive the two pinion gears on the shaft. Rotate the sleeve on the supporting shaft.
The knife holder of the shearing machine is an enclosed-welded structure, having high torsion resistance and good rigidity. It is connected to the frame by two ends of the support shaft, equipped with a shearing and return cylinder.
The shearing machine must be installed on a solid concrete foundation and fastened with anchor bolts. Install it by a secondary irrigation installation method. Place a level it on the work table for vertical and horizontal correction.
The left and back sides are higher than the right and front sides within the allowable range. All parts of the shearing machine must be inspected comprehensively. Add lubricating oil according to the lubrication diagram. Adjust the tightness of the V-belt and the spring tightness of the pressure plate. Adjust the tightness of the brake belt.
When adjusting the gap of the cutting edge, rotate the flywheel to bring the upper knife holder to the bottom dead center. Loosen the screw fixed the blade. Determine the gap value according to the thickness of the plate. Tighten gradually the bolts and nuts to adjust to the required gap. Finally, tighten all the bolts of the fixed blade of the worktable.

Press brake is a machine tool for bending sheet and plate material. Press brake is described by using two parameters, working length and force. Press brake must be operated by a skillful person who has specialized knowledge and skills, rather than an ordinary person.
How many types of press brakes are there?
What are the types of bending in press brake?
How to choose press brake?
The structural features and working principle of the mechanical press brake are the same as those of the mechanical press. The crank connecting rod mechanism is adopted to convert the rotating motion of the motor into the reciprocating motion of the slider. The mechanical press brake has a huge structure with high cost, which is often used for bending small and medium-sized parts. The advantage of the mechanical press brake is that the sliding block is parallel to the worktable, which has high precision and can withstand eccentric loads.
The hydraulic press brake is directly driven by hydraulic pressure. The hydraulic system can apply full pressure to the metal plate. If hydraulic press brake is overload, it can protect automatically. When bending sheet metal parts, the oil in the hydraulic cushion can be squeezed out under pressure. The upper die does a little retraction movement relative to the slider.
Pneumatic press brake uses compressed air as the power source. It is generally used for bending small plates. After the pneumatic press brake adopts CNC, it can save adjustment time.
There are three types of bending in press brakes that are commonly used. Each requires different strategies in press brake operation.
Coining means the process of pressing coins to get the images, numbers, and lettering on a coin. The workpiece is put under the tonnage of the press brake. It requires each bend to be exactly the same. The coining method requires the largest amount of tonnage in a press brake, usually 3 to 5 times that of the other bending methods.
Bottom bending doesn’t require as much tonnage as the coining method but does require more tonnage than the air-bending method. The metal is pushed down into the V-die to make a bend. There is a slight spring back. Bottom Bending is common on mechanical press brakes.
Air Bending is the most common form of press brake forming. It requires far less tonnage. A simple die can realize multiple angles with less tooling. It is much cheaper. There is less contact with the material being formed.
Determine the specifications and models of the press brake according to processing dimensions. In addition, you also consider the needs after the expansion of production.
After you have determined the specifications and models, you can contact the press brake manufacturer. The models produced by each manufacturer are very different. It is important to choose a proper press brake. Choose some manufacturers to compare with each other to know more about the quality, stability and after-sales service of the press brake.
The accuracy of the press brake needs to be the focus of selection. The accuracy standards of different machines have differences due to different press brakes. Some processing fields attach great importance to the processing effect of the plate.
Pay attention to the selection of molds. The loss of molds in the process of bending the plate is more serious.
