What are the parameters of Hydraulic Shearing Machine and CNC Shearing Machine

hydraulic shearing machine

The hydraulic shearing machine adopts a movable upper blade and a fixed lower blade. By adopting a reasonable blade gap, a shear force is applied to metal plates of different thicknesses, so that these plates can be broken and separated according to the required size.

　　 1. According to the shape of the scissors, the hydraulic shearing machine are divided into straight knife shearing machine and disc shearing machine. Straight knife shearing machine are divided into gantry shearing machine and throat shears according to their structure. According to the structure, disc shearing machine are divided into disc shearing machine, rolling shearing machine, multi-disc shearing machine and rotary trimming shearing machine.

　　2. According to the trajectory of the turret, according to the trajectory of the turret, the hydraulic shearing machine can be divided into the following types:

　　(1) The tool post moves along the vertical line. Because there is no rake angle, the cross section of the upper blade must be processed into a diamond shape, so there are only two edges (a rectangular blade with four edges can also be used, but the cutting quality is poor). The shear fracture of the tool holder is not at right angles to the surface of the plate.

　    (2) The upper blade can be machined into a rectangle with four blades along the forward inclination line (the angle between the blade and the vertical is 1°30’~2°), and the shear fracture is basically at right angles to the surface of the plate.

　    (3) The tool holder swings along an arc, and the cross section of the cutting blade should be made into a diamond shape, so there are only two blades. Since the upper blade is slightly inclined forward during the cutting process, the cutting quality is similar to that of a knife holder moving along the inclined line.

　  (4) The tool post swings along an arc, the rake angle can reach 300 degrees, and the welding groove can be cut out

Technical Parameters of CNC Shearing Machine

　　 Due to the large tonnage of the bottomed mold (about four times the tonnage of free bending), the stress that usually causes springback in the bending radius is reduced, thereby improving the forming angle. For the bending of the bottom mold, the angle of the mold is usually 86~90°. At the bottom of the stroke, there should be a gap between the male and female molds, which is slightly larger than the thickness of the mold. Material. Generally, the springback angle of the free bending mold of the CNC Shearing Machine on the new bending machine is less than or equal to 2°, and the bending radius is equal to 0.156 times the mold opening distance.

　　 When accepting the shearer die, there is no punch and die at the bottom of the stroke, which is enough to compensate for springback and make the material too tight and bend about 90%°. For free bending, the processing angle is 85° or less between the punch and the die. If the bending radius is smaller than the thickness of the material, a punch with the corner radius of the front end smaller than the thickness of the material must be received, and an embossing method is urgently needed. Therefore, it is necessary to increase the free bending pressure ten times.

　　 When the bending radius is large, it will not affect the main classification of shears and the quality of subsequent use. In order to choose a lower tonnage specification, the bending radius should be planned to be greater than the thickness of the material, and the free bending method should be accepted as much as possible.
The purchase time of the CNC Shearing Machine is not considered to be the future processing performance, or the maintenance of the CNC Shearing Machine is not done well, and the cycle period of the shearing machine is shortened, but the quality of the CNC Shearing Machine is so how can we improve some The efficiency of the CNC Shearing Machine, this is the life of the shearing machine?

1. Choose high-quality blades and accessories
The blade of the shearing machine is the tension component of the shearing machine. The hole between his cutting blade and the quality of the blade. Therefore, the jargon and qualification rate of shear products can be greatly improved.

2. Adjust the wear parameters between accessories
In the process of long-term use of dull activities, under the leverage, arc swing, and the gap between the screws, it is necessary to maintain the adjustment of automatic or manual components. The adjusted parameters, especially the parameter adjustment of CNC machine tools, can greatly improve the shear The machining accuracy of the force cutting machine!

3. Power system maintenance
If the effectiveness of the effective shearing power tube cannot be improved, such as the cylinder sealing and the stability of the voltage! The halving of other accessories will have a serious impact!

　　CNC Shearing Machine is a machine that uses one blade to reciprocate linear motion relative to another blade to cut the board. By moving the upper blade and fixing the lower blade, a reasonable blade gap is used to apply shearing force to metal plates of various thicknesses, so that the plates can be broken and separated according to the required size. CNC Shearing Machine is a forging machine whose main function is in the metal processing industry.Through the movable upper blade and the fixed lower blade, a reasonable blade gap can be applied to the metal shears of various thicknesses. It is one of the forging machines and the main function is the metal processing industry. Products are widely used in aviation, light industry, metallurgy, chemical, construction, shipbuilding, automobiles, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment.
