1. adjust the angle baffle Put the template on the table and align the knife edge to adjust the angle baffle and fix it. Then adjust the rear baffle according to the template. Use the angle baffle and the rear baffle together for positioning during cutting.
2. adjust the front baffle, lean the rear baffle against the lower knife edge and then lean the sample plate against the rear baffle, lean the front baffle against the sample plate and fix it. Loosen the tailgate, remove the sample plate and install the plate for shearing.
3. adjust the tailgate, align the template topping with the knife edge, then lean the tailgate against the template, fix and remove the template, then install the plate for shearing.

There are many types of shearing machines that can be divided into different types according to their technical uses and structural types.
1. the upper and lower blades of the plate shearing machine are usually skewed at a skew angle of 1-6. The shearing force of the inclined blade shearing machine is smaller than that of the flat blade shearing machine, so the motor power and the weight of the whole machine are greatly reduced. This kind of shearing machine is divided into hydraulic transmission and mechanical transmission according to the main transmission system.
2. flat blade shearing machine has good shearing quality, small distortion and deformation, but large shearing force and large energy consumption. More mechanical transmission. The upper and lower blades of the shearing machine are parallel to each other, which is often used in rolling mills for hot shearing of preliminary rolling billets and slabs. According to its shearing method, it can be divided into upper cutting type and lower cutting type.
3. multi-use shearing machine
1. The combined punching and shearing machine can finish the shearing of the plate and can shear the profile, which is mostly used in the blanking process.
2. The sheet metal bending and shearing machine can complete two technologies of shearing and bending on the same machine.
Special plate shears for 4. are of special use when more equipment is used in cooperation with other equipment.
1. The plate opening and leveling line shearing machine is used for the high-speed plate shearing machine planned for the cooperative production line speed cutting request on the plate opening and leveling line. The thick plate line is mostly equipped with hydraulic high-speed plate shearing machine and pneumatic plate shearing machine on the thin plate line. The high-speed line is equipped with flying shears with high continuous production efficiency.
2, cold bending forming line shearing machine such as car longitudinal beam cold bending line, carriage side baffle production line, color steel plate forming line and other production line configuration of special shearing machine.
3, steel structure production line shearing machine is mostly used for angle steel, H-beam automatic production line finishing shearing process.

When the customer buys the plate back, he should pay attention to the maintenance of the plate bending machine. The maintenance of the plate bending machine is very important. The use of a good plate bending machine is also related to the maintenance of the plate bending machine at ordinary times. The structure of the plate rolling machine is of three-roller symmetry type. The upper roller moves vertically up and down at this position in the center of the two lower rollers. The hydraulic oil in the hydraulic cylinder acts on the piston to obtain hydraulic transmission. The two rollers rotate, and the output gear of the reducer is kneaded with the teeth of the lower roller to provide torque for the rolling plate. The machine tool has compact structure and convenient operation and maintenance.

Let me introduce you to some small methods of maintenance.

1, according to the provisions of the machine lubrication diagram, according to the requirements of the oil cup lubrication and manual lubrication points for oil.
2. After the power is turned on, carry out the lifting movement of the lower roller in both positive and negative directions and the upper roller, and check whether there is any abnormal sticking phenomenon in each movement.
3. During operation, if irregular noise, impact and other abnormal phenomena are found, stop the machine immediately for inspection.
4, in strict accordance with the coil processing procedures and operating methods to operate, in the upper roller to the limit position, to pay great attention to the operation of the equipment.
5. During the operation, all personnel should coordinate with each other and obey the command of the person in charge of the rolling plate. Without a password, it is forbidden to start the machine.
6. After the main drive stops, the upper roller can be lifted and lowered, the tilting and resetting of the turning bearing and the lifting of the upper roller can be carried out.
7, large plate bending machine plate bending operation should pay great attention to prevent the hand is pressed by the steel plate and steel plate rolled together.
8. When lifting the steel plate or drum with the crane, be careful not to collide with the machine.
The maintenance of the bending machine is very important, and good maintenance can effectively extend the service life of the bending machine.

The maintenance of the three-roll plate bending machine should pay attention to the oil cup lubrication and manual lubrication points of the plate bending machine according to the instructions. When in use, according to the specified parameters of the three-roll plate bending machine, overload and improper use are not conducive to the maintenance of the plate bending machine. After the bending machine is powered on, the lifting movement of the lower roller in the forward and reverse directions and the upper roller shall be carried out, and the movement shall be checked for abnormal jamming. When in use, it should be strictly operated according to the processing procedures and operating methods of the bending machine. After the plate bending machine is finished, the work site should be cleaned up, and the corresponding maintenance work should be done well, and the power supply of the equipment should be turned off in time.

Two-roll bending machine function

The two-roller machine is composed of two rollers, which is different from the three-roller machine in that the three rollers of the three-roller machine are all rigid rollers and are made of metal. The two-roller machine has only one rigid roller, while the other is a flexible roller made of rubber. When working, the servo motor drives the flexible roller to press the rigid roller, and the deformation of the flexible roller causes the material to deform into a qualified shape. Due to the adoption of flexible rollers, the two-roller machine has no wear on the surface of the plate and is very suitable for stainless steel materials.

How efficient is the two-roll machine?

The efficiency of the two-roller machine is very high, because it uses flexible rollers, so the material does not need to be pre-bent, and of course it does not need to be trimmed. After eliminating the above two procedures, the two-roll machined plate is formed at one time, and the processing speed is only related to the length of the plate, and the speed of the active roller is 1.33 m/min. For example, a steel plate is also rolled into a steel cylinder of a gas tank. The three-roller machine needs to go through the procedures of pre-bending-rolling back and forth-trimming-shaping-welding, which takes about 7-8 minutes/piece except welding. The two-roller machine can be directly welded only through a one-time roller system.

What shape is your two-roller machine?

Cylinder, custom cylinder, ellipse, cone, etc. All rules and custom circles. Because the two-roll machine is a forming machine, we can make a cylindrical workpiece with any radius by giving different pressures to the workpiece during the traveling process. The special-shaped two-roll machine can even realize shapes with sharp angles, such as polygons, irregular polygons and even mixed shapes. With different molds can even make angle-arc-angle workpiece.

How thick is the plate of the two-roller functional roll?

180mm diameter can be rolled 3mm plate. The larger the diameter, the thicker the sheet can be rolled.

How about the service life of the two roller machine than the three roller machine?

The rigid part of the two-roller machine is the same as the three-roller machine, but the structure is more streamlined than the three-roller machine. The accessories factory provides us with accessories solutions. So the life is longer than three roller machine. If the rubber roller is worn out due to long-term work, it can be removed and the problem is solved.
