Description

Technical Field

[0001] The utility model belongs to the technical field of shearing machines, and in particular relates to a shearing tool holder with multiple blades. Background Art

[0002] The shearing machine is a hydraulically driven machine tool. It is suitable for metal recycling plants, scrap car dismantling yards, and smelting and casting industries. It can cold-cut and press flanging various shapes of steel and various metal materials. The hydraulic shearing machine has a variety of designs according to the operating requirements. Among them, the shearing machine tool holder is the most critical structure of the shearing machine, which directly affects the working performance of the shearing machine.

[0003] The multi-section tool holder is a shearing tool suitable for wide-width plates. When working, the tool holder is driven downward by a hydraulic mechanism to complete the shearing of the plates. During operation, the tool holder slides in a specific track. When the conventional multi-section tool holder is shearing, due to the inclined setting of the multi-section blades, an inclination force will be generated during the shearing process, which will cause one side of the tool holder to be subjected to lateral force, resulting in poor stability during the shearing process, and then causing rapid wear of the wear-resistant block at the connection between the tool holder and the guide rail, affecting the operating stability and service life of the shearing machine tool holder, and seriously affecting the shearing effect. Utility Model Content

[0006] Preferably, two groups of the first transverse blades are respectively arranged at the leftmost and rightmost ends of the multi-section knife group, N groups of the second transverse blades are arranged between the two groups of first transverse blades, and a group of longitudinal blades is arranged between every two adjacent groups of transverse blades.

[0007] Preferably, the multi-section knife set has a downward inclination angle of 9 degrees from left to right, the first transverse blade and the second transverse blade have a downward inclination angle of 10 degrees from left to right, and the width of the first transverse blade is greater than the width of the second transverse blade.

[0008] Preferably, the angle between the longitudinal blade and the horizontal plane is set to 7 degrees.

[0009] Preferably, a front wear-resistant plate and a rear wear-resistant plate are provided at the connection between the frame assembly weldment and the guide rail, and a plurality of shear cylinders are provided on the top of the frame assembly weldment.

[0010] Preferably, the multi-section blade set is a stepped structure, and the longitudinal blades are perpendicular to the transverse blades of adjacent groups.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The multi-section knife group is arranged downwardly from left to right, and different groups of transverse blades do not work at the same time to shear, thereby improving the shearing capacity of each section of the blade. The structure of the multi-section knife group is low on the left and high on the right. When it goes down, it will guide the web to the right, generating a tilting force to the right. In the present technical scheme, the transverse blade is also arranged obliquely, and the transverse blade is tilted upward. The angle of the transverse blade tilting upward is approximately equal to the angle of the multi-section knife group tilting downward, which is opposite to the tilting force of the multi-section knife group during the shearing process, thereby offsetting the influence of the tilting force, so that the knife holder remains stable and efficient when running downward, the left and right sides of the knife holder are balanced, and the wear-resistant plate is guided evenly, which is beneficial to improving the service life of the wear-resistant plate and the multi-section knife group, and at the same time makes the shearing effect of the shearing machine more stable and efficient, and the use effect is better.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Reference Figure 1-2A multi-segment blade shearing tool holder comprises a frame assembly weldment 1, a multi-segment blade set inclined downward from left to right is arranged at the bottom of the frame assembly weldment 1, the multi-segment blade set comprises two groups of first transverse blades 2, N groups of second transverse blades 3 and N+1 groups of longitudinal blades 4, the first transverse blades 2 and the second transverse blades 3 are both arranged inclined upward from left to right, and the upward inclination angle of the first transverse blades 2 and the second transverse blades 3 is adapted to the downward inclination angle of the multi-segment blade set.

[0018] In view of the problem that the existing multi-stage shearing machine tool holder generates a tilting force during the shearing process, which causes one side of the tool holder to be subjected to a lateral force, resulting in poor stability during the shearing process, a multi-stage blade shearing tool holder is provided in the present scheme, and the multi-stage knife group of the shearing tool holder is tilted downward from left to right, and the lateral blades of different groups do not shear at the same time, thereby improving the shearing capacity of each blade segment, and the multi-stage knife group has a structure with low left and high right, which will guide the web to the right when it goes down, thereby generating a tilting force to the right, and the present technical scheme also tilts the lateral blade, and the lateral blade is tilted upward, and the angle at which the lateral blade is tilted upward is approximately equal to the angle at which the multi-stage knife group is tilted downward, which is opposite to the tilting force of the multi-stage knife group during the shearing process, thereby offsetting the influence of the tilting force, so that the tool holder remains stable and efficient when running downward, the left and right sides of the tool holder are subjected to balanced forces, and the wear-resistant plate is guided symmetrically, which is beneficial to improving the service life of the wear-resistant plate and the multi-stage knife group, and at the same time makes the shearing effect of the shearing machine more stable and efficient, and the use effect is better.

[0019] Furthermore, two groups of first transverse blades 2 are respectively arranged at the leftmost and rightmost ends of the multi-section blade group, N groups of second transverse blades 3 are arranged between the two groups of first transverse blades 2, and a group of longitudinal blades 4 is arranged between every two adjacent groups of transverse blades.

[0020] In this embodiment, the length of the first transverse blade 2 is set to 570 mm, the length of the second transverse blade 3 is set to 500 mm, and two groups of first transverse blades 2 with slightly longer lengths are respectively arranged at the starting end and the end to facilitate cutting stability; in this embodiment, two groups of second transverse blades 3 are arranged, and three groups of longitudinal blades 4 are arranged.

[0021] Furthermore, the multi-section blade set has a downward tilt angle of 9 degrees from left to right, the first transverse blade 2 and the second transverse blade 3 have a downward tilt angle of 10 degrees from left to right, and the width of the first transverse blade 2 is greater than the width of the second transverse blade 3.

[0022] Through this technical solution, the multi-section knife group is tilted downward at an angle of 9 degrees from left to right, forming an overall shearing angle of 9 degrees, which can guide the web stably to the right; at the same time, the first transverse blade 2 and the second transverse blade 3 are tilted downward at an angle of 10 degrees from left to right, and the angle of the transverse blade is approximately equal to the overall angle of the multi-section knife group, thereby effectively balancing the tilting force of the multi-section knife group.

[0023] Furthermore, the angle between the longitudinal blade 4 and the horizontal plane is set to 7 degrees.

[0024] The longitudinal blade 4 is 410mm long, and the horizontal angle of each blade is 7 degrees. The angle is designed to be low on the outside and high on the inside. When shearing downward, each blade does not work at the same time to ensure the maximum shear force and the formed material is square and regular.

[0025] Furthermore, a front wear-resistant plate 5 and a rear wear-resistant plate 6 are provided at the connection between the frame assembly weldment 1 and the guide rail, and a plurality of shear cylinders 7 are provided on the top of the frame assembly weldment 1 .

[0026] The wear-resistant plate is used to dock with the guide rail of the shearing machine to play a role of lubrication and guidance. A plurality of shearing cylinders 7 are located above the frame assembly weldment 1 to drive the frame assembly weldment 1 to move up and down, thereby cutting the web.

[0027] Furthermore, the multi-section blade set is a stepped structure, and the longitudinal blades 4 are perpendicular to the transverse blades of the adjacent groups.

[0028] Working principle: The multi-section blade group of the shearing knife holder is tilted downward from left to right, and different groups of transverse blades do not work at the same time, thereby improving the shearing capacity of each blade. The structure of the multi-section blade group is low on the left and high on the right. When it goes down, it will guide the web to the right, generating a tilting force to the right. This technical solution also tilts the transverse blade, and the transverse blade is tilted upward. The angle of the transverse blade tilting upward is approximately equal to the angle of the multi-section blade group tilting downward, which is opposite to the tilting force of the multi-section blade group during the shearing process, thereby offsetting the influence of the tilting force, so that the knife holder remains stable and efficient when running downward. The left and right sides of the knife holder are balanced, and the wear-resistant plate is guided evenly, which is conducive to improving the service life of the wear-resistant plate and the multi-section knife group, and at the same time makes the shearing effect of the shearing machine more stable and efficient, and the use effect is better. .
