Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal part production, and specifically relates to a shearing device for sheet metal part production. Background Art

[0002] In the production of sheet metal parts, the shearing device is an indispensable and important piece of equipment, which is used for precise and efficient shearing of metal sheets. The shearing machine is a device specifically used for shearing metal sheets. It uses the relative movement between the upper knife and the lower knife to cut the metal sheets, achieving precise cutting of the metal sheets. The shearing machine is usually applied in fields such as sheet metal processing, machinery manufacturing, automobile manufacturing, shipbuilding, and electronic equipment manufacturing in the metal processing industry;

[0003] First, in the prior art, usually one side of the sheet metal is fixed by a single pressing arm. When cutting with unilateral fixation, the other side of the sheet metal is not effectively supported and fixed, which easily causes the sheet metal to shake or displace during the cutting process, thereby affecting the cutting accuracy and effect, and the sheet metal is subjected to uneven forces during the cutting process. Unilateral fixation easily causes burrs or deformation on the cutting edge, reducing the quality of the product;

[0004] Second, in the prior art, the shearing tool is usually completely parallel to the sheet metal. When encountering materials with higher hardness, the required shearing force is larger and the energy consumption is higher. Therefore, a shearing device for sheet metal part production is proposed. Summary of the Invention

[0005] The purpose of the utility model is to provide a shearing device for sheet metal part production to solve the problems raised in the above background art.

The second hinge seat drives the main pressure rod to swing through the first support rod, so that the main pressure rod is parallel to the sheet metal body, pressing the sheet metal bodies on both sides of the cutter. At the same time, the auxiliary pressure rod is parallel to the main pressure rod to fix the sheet metal body in a larger range, preventing the sheet metal from shaking or displacing during the cutting process, thereby affecting the cutting accuracy and effect and reducing the product quality.

[0024] In this embodiment, specifically: a first support frame 13 is fixedly connected to the upper surface of the sheet metal shearing workbench 1. A second electric hydraulic push rod 14 is fixedly connected to the bottom of the first support frame 13. A second support frame 15 is fixedly connected to the bottom of the second electric hydraulic push rod 14. One end of the second support frame 15 is internally hinged with a connecting rod 16. A cutter 17 is fixedly connected to the lower surface of the connecting rod 16. A first through hole 181 and a second through hole 182 are formed in the connecting rod 16. A first sliding rod 19 is slidably connected in the first through hole 181. A second sliding rod 20 is fixedly connected to the outer wall of the first sliding rod 19. The second sliding rod 20 is slidably connected inside the second through hole 182. A threaded rod 21 is fixedly connected to the top of the second sliding rod 20. The threaded rod 21 is threadedly connected to the second support frame 15. A handle 22 is fixedly connected to the top of the threaded rod 21.

[0025] In this embodiment, specifically: there are two support plates 2. A gap is provided between the two support plates 2. The cutter 17 is located above the gap between the two support plates 2. Two groups of main pressure rods 7 and support seats 9 are located on both sides of the cutter 17. The two groups of main pressure rods 7 and support seats 9 press the support plates 2 on both sides of the connecting rod 16 to prevent the support plates 2 from moving and affecting the shearing effect.

With the cooperation of the second support rod 8 and the support seat 9, the second hinge seat 23 drives the main pressure rod 7 to swing through the first support rod 6, so that the main pressure rod 7 is parallel to the sheet metal body 3, and the sheet metal bodies 3 on both sides of the cutter 17 are pressed. At the same time, under the limitation of the first limiting plate 11, the auxiliary pressure rod 10 is parallel to the main pressure rod 7 to fix the sheet metal body 3 in a larger range, preventing the sheet metal from shaking or displacing during the cutting process, thus affecting the cutting accuracy and effect and reducing the product quality; when processing harder materials, the staff rotates the handle 22, and the rotation of the handle 22 drives the threaded rod 21 to rotate. Since the threaded rod 21 is threadedly connected to the second support frame 15, the threaded rod 21 moves downward, thereby adjusting the angle of the cutter 17. Appropriate cutting angle adjustment helps to reduce the cutting force.
