Description

Technical Field

[0001] The utility model relates to the technical field of leveling devices, in particular to a punching and leveling device for a metal stamping die with point-touch positioning. Background Art

[0002] In cold stamping processing of metal stamping dies, a die installed on a press applies pressure to a material to cause separation or plastic deformation, thereby obtaining the required parts. Punching is a relatively common metal processing technology in the manufacturing industry. Because punching processing has unique advantages, it is a more cost-effective process for punching holes in metal workpieces. Secondly, holes of various shapes and sizes can be punched through punching processing. In addition, the stamping process is very fast, and a stamping can be completed in just a few seconds. However, when punching the material, due to the uneven surface of the material, the uneven thickness of the material, and the vibration during the punching process, the punched part will be uneven, and the punched part needs to be leveled separately, which increases the difficulty of punching. Moreover, the existing devices cannot quickly position the metal during punching and cannot guarantee the processing accuracy. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a punching and leveling device for a metal stamping die with point-touch positioning, which aims to solve the technical problems of lacking a leveling effect and being unable to quickly position the punching position in the prior art.

[0004] The technical solution of the utility model is as follows: A punching and leveling device for a metal stamping die with point-touch positioning includes a lower die base; it also includes a first lifting cylinder, an upper die base, a lower die head and a leveling component, a longitudinal adjustment component, a support component, a third lifting cylinder, an upper template, an upper die head, a guide wheel and a pressure plate; on the rear side of the upper end of the lower die base, there are symmetrically distributed first lifting cylinders on the left and right; the telescopic ends on the upper sides of the first lifting cylinder and the other first lifting cylinder are fixedly connected with the upper die base; on the upper end of the lower die base, a lower die head and a leveling component and symmetrically distributed longitudinal adjustment components are installed in sequence from the inside to the outside; in the middle of the upper end of the lower die base, there is a support component installed outside the lower die head and the leveling component; on the upper end of the upper die base, there are symmetrically distributed third lifting cylinders on the left and right; the telescopic end on the lower side of the third lifting cylinder passes through the upper die base and is fixedly connected with the upper template; the lower end of the upper template is fixedly connected with an upper die head matching the lower die head and the leveling component; on the front and rear sides of the upper ends of the longitudinal adjustment components, there are equidistantly distributed guide wheels rotatably connected; on the lower end of the upper die base, there is a pressure plate installed.

[0005] Preferably, the lower die base is placed in a stable position. The raw material to be punched is placed above the longitudinal adjustment assembly and the support assembly on the left side. The longitudinal adjustment assembly controls the guide wheels to move inward synchronously, so that the guide wheels are attached to the front and back sides of the raw material. The raw material is placed on top. The first lifting cylinder controls the lower die base to descend, and the pressure plate presses down the support assembly. The support assembly synchronously descends to be flush with the lower die head and the leveling assembly. The lower die head and the leveling assembly slightly lift the part to be punched upward. The third lifting cylinder controls the upper template and the upper die head to descend, and cooperates with the lower die head and the leveling assembly to complete the punching and leveling of the raw material.

[0006] Preferably, the lower die head and the leveling assembly include a lower die head body; a through hole aligned vertically with the upper die head is provided on the lower die head body; a second lifting cylinder is fixedly connected inside the through hole; a leveling convex block is installed on the retractable end on the upper side of the second lifting cylinder. The second lifting cylinder is used to control the lifting of the leveling convex block, so as to achieve the purpose of leveling without affecting punching.

[0007] Preferably, the upper end of the leveling convex block is a semi-circular structure protruding upward; the position of the upper end of the leveling convex block is higher than the upper end of the lower die head body. The raw material is lifted upward by the leveling convex block, so as to provide a reverse force during punching, thereby avoiding deformation around the punching position.

[0008] Preferably, the longitudinal adjustment assembly includes a fixed seat; a double-headed ball screw is rotatably connected inside the fixed seat; screw pairs symmetrically distributed front and back are installed outside the double-headed ball screw. The screw pairs are used to convert the rotary motion of the double-headed ball screw into a linear motion. As the screw pairs move synchronously outward or inward, the purpose of positioning the product to be punched is achieved.

[0009] Preferably, the screw pair is fixedly connected with a mounting plate at the upper end; a motor for driving the double-headed ball screw is installed at the front end of the fixed seat; the guide wheel is rotatably connected to the upper end of the mounting plate. The power is transmitted to the double-headed ball screw through the motor, so as to drive the double-headed ball screw to rotate and complete the position adjustment of the screw pair.

[0010] Preferably, the support assembly includes a rectangular support plate; springs are fixedly connected to the four corners at the lower end of the rectangular support plate; positioning columns symmetrically distributed front and back are fixedly connected to the lower end of the rectangular support plate; the distance from the lower end of the positioning column to the upper end of the lower die base is equal to the distance from the upper end of the rectangular support plate to the upper end of the lower die head body, ensuring that after the positioning column descends, the rectangular support plate is flush with the upper end of the lower die head body, so as to ensure the support effect on the raw material.

[0011] Preferably, guide grooves symmetrically distributed left and right are provided on the inner walls of the front and rear ends of the rectangular support plate; guide sliders matching the guide grooves are fixedly connected to the outside of the lower die head body, and the rectangular support plate is limited during the lifting and lowering process to prevent the rectangular support plate from shifting.

[0012] Advantages of the present utility model: By adopting multi-point support, the position to be punched is lifted upward, and then during punching, the material below the hole is supported, which can avoid the problem of curling in the punched part. Therefore, additional leveling treatment is not required after punching, reducing the equipment during punching, while reducing the difficulty of punching, ensuring the punching accuracy, and also providing a guiding mechanism to position the raw material during feeding, thereby ensuring the accuracy of the punching position.
