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.

The V groover machine is also known as score-folding, V-cutting, and back-scoring. V groover machining facilitates the bending or folding of various materials and forms a V-shaped cut along the surface. The cut along the fold line acts as a hinge, allowing to achieve 90-degree bends with relatively small bending radii.
What are the errors of V groover machine?
How to maintain V groover machine?
What should be considered when using V groover machine?
The V groover machine has large vibration. That’s because the two diamond cut-off wheels are deformed. The splint and distance ring are worn. The output shaft bearing is damaged. You can replace the same diamond cutting wheel, the splint, distance ring, and the bearing.
The V groover machine motor is overheated. The diamond cut-off wheels are too blunt or not parallel. The V groover machine is overload. Reduce the cutting speed and depth. Replace the special diamond cut-off wheels, the bearing or reassemble.
The motor is weak. It can be caused by the rotor or stator. The voltage is low. Another reason is that the brush is too short or the spring loses its elasticity. Check and replace the rotor, the stator, the brush and spring. Check whether the wire cross-sectional area, length, and connection are reliable.
If there is any noise of V groover machine, it may have damaged gear or bearing. The stator and rotor is failure. There is the chance that the brushes have poor contact. Check and replace the gear, the bearing, the rotor, the stator and the brush. Tighten the stator assembly fixing bolt.
Completely clean the V groover machine once every six months. Use a brush to remove the external dust and a professional detergent to clean the dusty places. It is necessary to apply engine oil to the guide rails to prevent mechanical damage. Put in a ventilated place to dry to avoid rust.
When V groover machine stops running, it needs to check whether there are loose screws of internal related parts.
Before starting the V groover machine, make sure that the bearings and other parts are reasonably smooth. The water temperature ranges from 40°C to 50°C. If necessary, anti-freezing solution is poured in winter.
Pay special attention to the maintenance of the V groover machine engine during normal use. The engine should not be overloaded.
Before starting the automatic V groover machine, check carefully whether the tool, nut and each screw are firm. If any, tighten in time!
Pay attention to the cutting direction when installing the tool. It is not allowed to reverse. The main tool turns clockwise.
Confirm whether the pneumatic device is turned on. Press the workpiece on the movable push table to close to the positioning plate. Keep your hands away from the knife edge.
When the V groover machine breaks down, the power supply should be cut off in time. A professional person should be sent to repair and adjust. It is forbidden to run the V groover machine until it is work.
Before processing the material, check whether there are iron nails, sand-rock joints, and others on the V groover machine. The stainless steel groover prevents damage to the tool joints and hurts people.
Cut off the power supply when cleaning, wiping lubricating oil, removing saw blades and cleaning chips.
The V groover machine must be operated, adjusted and maintained by professional personnel. Workers should wear earplugs, goggles and other protection supplies during operation.
The maintenance is carried out in accordance with the system.

LZK introduces the TL 8525 to its line of tube laser cutting machines. The newly designed new generation of tube lasers is equipped with many high performance features to optimize tube cutting for even the most complex applications. With a large feed length of 8500 mm, the TL 8525 can process round or square tubes up to 250 mm in diameter. Standard machine features include a 45-degree 3D tilt axis cutting head for beveling, a 6-position front loader and a wide X-axis cutting head range of 1190 mm to maximize material utilization.
Designed for productivity
The TL 8525 is designed for high productivity. The machine can process pipe lengths up to 8500 mm, with a maximum part length of 3000 mm, and can clamp and cut pipe diameters up to 250 mm. The 400 mm Z-axis allows for larger profiles to be cut.
A new design with welded steel construction provides high rigidity and dynamics. Pre-assembled collets and stabilizers help to set up and start the machine quickly and easily. The TL 8525 maintains the compact footprint of other TL models and offers the advantage of accessibility to all sides of the machine. Because loading and unloading are handled on one side, the machine can be installed in tight spaces or against a wall.
Leading-edge features are built-in
The TL 8525 is equipped with key features typically offered as options on comparable tube laser cutting machines for the widest range of uses in cutting round, square, rectangular or other profiles, regardless of complexity.
A 45 degree 3D tilt cutting head is standard. The multi-axis cutting head allows high-precision bevel cutting of round, square, rectangular and profiled tubes, cutting complex profiles and channels, and can be used for weld-ready cutting of thick-walled tubes.
A 6-position front loader is also standard. This semi-automatic loading machine offers a high degree of material loading flexibility. It can handle up to six tubes and offers six positions, even for tubes with a maximum diameter of 250 mm. The system can load different types of tubes of different sizes and can be interrupted in the middle of the process to add new tubes. Unlike bundle feeder systems, there is no need to wait to rebind a bundle in the loader, remove it from the machine, and then reload a new bundle. The flexibility of material loading effectively meets the needs of small batches and long production runs.
The wide 1190 mm X-axis cutting head range allows processing along larger lengths of tubing, including behind the stabilizer unit. The ability to handle more tube and reduce material waste makes tube cutting operations more productive and profitable.
Other key features include a programmable table in the outfeed area. The servo-controlled table features a tilt function for smooth part release and is integrated into a 3 m part evacuation conveyor. The conveyor uses multiple compartments to safely separate and secure parts - even round or longer tubes - as they move along the conveyor.
The TL 8525 features a high degree of automation, including automatic tube loading, automatic tube centering, and automatic setup and adjustment of the chucks and stabilizer. A powerful smoke extraction system integrated into the chuck automatically removes approximately 4,000 cubic meters of smoke per hour from the cutting area.
The TL 8525 is equipped with a 2 kW IPG fiber laser source capable of cutting a range of ferrous and non-ferrous materials. A 4 kW laser source is optional.
