Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to an anti-torsion device for shearing machines. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. By using a reasonable blade gap between the moving upper blade and the fixed lower blade, shearing force is applied to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions.

[0003] During the operation of a shearing machine, the shearing force can easily cause twisting and deformation of components such as the blade holder. This not only affects the shearing accuracy but may also lead to accelerated blade wear and shortened equipment lifespan. Existing shearing machines often employ complex and costly anti-twist structures with unsatisfactory anti-twist effects, failing to meet the high precision and stability requirements of actual production.

[0011] As a preferred embodiment of this utility model, the guide sleeve is symmetrically welded to the inner wall of the housing, the anti-torsion rib plate is an X-shaped structure, and the reinforcing beam is an I-shaped structure.

[0012] As a preferred embodiment of this utility model, a baffle plate is welded to the inner wall of the housing, a material sliding ramp is provided below the baffle plate, and the stable support seat is fixed to the housing by bolts.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figures 1-6 This utility model discloses an anti-torsion device for a shearing machine, including a machine housing 1 and an electrical box 2 located on one side of the machine housing 1, as well as a placement table assembly 3, a shearing assembly 4, an upper blade holder anti-torsion assembly 5, a lower blade holder anti-torsion assembly 6, and a hydraulic assembly 7, wherein:

[0026] Please refer to the appendix. Figure 5 The shearing assembly 4 includes an upper blade 41, and a lower blade 42 is provided below the upper blade 41 at a offset position. The upper blade 41 is fixed to the upper blade holder 43 by bolts, and the lower blade 42 is fixed to the lower blade holder 44 by bolts.

[0027] Please refer to the appendix. Figure 4 The upper tool holder anti-torsion assembly 5 includes a reinforcing crossbeam 51, which is fixed to the top of the upper tool holder 43 by several bolts. Several anti-torsion ribs 52 are welded between the side wall of the upper tool holder 43 and the reinforcing crossbeam 51. Guide posts 53 are welded to the bottom of both ends of the reinforcing crossbeam 51. Specifically, the anti-torsion ribs 52 improve the connection strength between the reinforcing crossbeam 51 and the upper tool holder 43.

[0028] Please refer to the appendix. Figure 6The lower tool holder anti-torsion component 6 includes a stable support 61, which is located below the lower tool holder 44. Several damping springs 62 are welded between the stable support 61 and the lower tool holder 44. Several positioning posts 63 are provided on the surface of the stable support 61. Specifically, the damping springs 62 prevent the lower tool holder 44 from receiving high-frequency hard impacts, thereby improving the service life of the lower tool holder 44.

[0029] The guide post 53 is fitted into the guide sleeve 11 and slides together. The bottom surface of the lower tool holder 44 is provided with several positioning grooves 64, which are fitted into the positioning post 63 and slide together.

[0030] In this embodiment, the crossbeam 51 and the anti-torsion rib plate 52 work together to enhance the anti-torsion ability of the upper blade holder 2 and effectively resist the torsional deformation caused by shearing force. The shock-absorbing spring 62 buffers the impact force on the lower blade holder 44. The cooperation between the positioning column 63 and the positioning groove 64 ensures the stability of the lower blade holder 44 during operation and reduces the tendency of the entire shearing machine to twist due to the instability of the lower blade holder 44. Example 2

[0031] Based on the above embodiment 1, please refer to the appendix. Figure 2 as well as Figure 3 The placement platform assembly 3 includes a support platform 31, which is welded to one side of the housing 1. Two base plates 32 are symmetrically welded to the top surface of the support platform 31, and a steel plate 8 is provided above the base plates 32.

[0032] The guide sleeve 11 is symmetrically welded to the inner wall of the housing 1. The anti-torsion rib plate 52 has an X-shaped structure, and the reinforcing beam 51 has an I-shaped structure. Specifically, the X-shaped structure of the anti-torsion rib plate 52 enables the force to be evenly transmitted and dispersed in multiple directions, while the upper and lower flanges of the I-shaped structure of the reinforcing beam 51 can effectively resist the tensile and compressive stresses generated during bending. When the upper tool holder 43 is subjected to torsion, it can more effectively resist the torque.

[0033] A baffle plate 12 is welded to the inner wall of the housing 1. A sliding ramp 13 is provided below the baffle plate 12. The stabilizing support 61 is fixed to the housing 1 by bolts. Specifically, the baffle plate 12 ensures the consistency of the shearing length.

[0034] The bottom of the stable support base 61 is provided with several support feet 65, and the bottom of the support feet 65 is provided with rubber anti-slip pads 651. The rubber anti-slip pads 651 abut against the housing 1. Specifically, the rubber anti-slip pads 651 improve the stability of the support feet 65.

[0035] The hydraulic assembly 7 includes a hydraulic cylinder 71, which is equipped with a hydraulic column 72. The hydraulic column 72 is fixed and locked to the bottom ends of the upper tool holder 43 by bolts.

[0036] In this embodiment, the steel plate 8 is pushed into the space between the upper blade 41 and the lower blade 42. The electrical box 2 activates the hydraulic cylinder 71 to drive the hydraulic column 72 to extend and retract up and down, thereby driving the upper blade 42 on the upper blade holder 43 to move up and down, and cooperate with the lower blade 42 to perform the shearing operation.

[0037] The working principle and usage process of this utility model are as follows: When the shearing machine is working, the steel plate 8 is first placed on the base plate 32 on the support platform 31, and the steel plate 8 is pushed into the space between the upper blade 41 and the lower blade 42. The electrical box 2 starts the hydraulic cylinder 71 to drive the hydraulic column 72 to extend and retract up and down, thereby driving the upper blade 42 on the upper blade holder 43 to rise and fall up and down, and cooperate with the lower blade 42 to perform the shearing operation. After shearing, the cut part slides down from the material sliding slope 13 for collection.

[0038] When the upper tool holder 43 moves up and down, the guide column 53 slides up and down in the guide sleeve 11, which plays a guiding role, enhances the movement stability of the upper tool holder 43, strengthens the synergistic effect between the crossbeam 51 and the anti-torsion rib plate 52, enhances the anti-torsion ability of the upper tool holder 2, and effectively resists the torsional deformation caused by shear force.

[0039] During shearing, the steel plate 8 presses against the lower blade holder 44. The impact force on the lower blade holder 44 is buffered by the shock-absorbing spring 62. The cooperation between the positioning column 63 and the positioning groove 64 ensures the stability of the lower blade holder 44 during operation, reducing the tendency of the entire shearing machine to twist due to the instability of the lower blade holder 44, thereby improving the shearing accuracy and stability of the shearing machine.
