Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a stamping forming device with a protective function. Background Art

[0002] Auto parts are the various units that make up the whole car and are a kind of product that serves the car. There are many kinds of auto parts. Pressing is a forming processing method that relies on presses and molds to apply external force to plates, strips, pipes and profiles to make them produce plastic deformation or separation, so as to obtain workpieces of the desired shape and size. Auto parts require stamping work in the production process.

[0003] For example, publication number CN219484022U discloses a protective device for stamping. The device places the parts to be stamped on the workbench, then turns on the electric slide switch to drive the electric slider and the transparent protective plate to slide down, thereby shielding the stamping position to prevent iron filings from splashing out. When the transparent protective plate slides down to the bottom, the electric slide switch is turned off to continue the subsequent stamping work.

[0004] However, the above-mentioned protective device is less practical when used. Although the above-mentioned protective device can protect against iron chips flying through a transparent protective plate, the protective device requires the user to manually open and close it again and again. Every time an automotive accessory needs to be stamped, it must be manually operated twice, which is more troublesome when used. In view of this, we propose a stamping forming device with a protective function. Utility Model Content

[0005] The purpose of the utility model is to provide a stamping forming device with a protective function to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stamping forming device with a protective function, comprising a workbench, the inner wall of the workbench is provided with a stamping structure, a placing table is fixedly installed on the inner wall of the workbench, fixed plates are fixedly installed on both sides of the placing table, and a protective structure is provided inside the workbench to prevent iron chips from splashing.

[0007] Preferably, the protection structure includes a slide groove opened on both sides of the inner wall of the workbench, a slide rod is fixedly installed on the inner wall of the slide groove, a sleeve is slidably connected to the surface of the slide rod, a sliding block is fixedly installed on the side wall of the sleeve, a return spring is arranged on the surface of the slide rod, a U-shaped protective plate is slidably connected to the surface of the fixed plate, one end of the connecting rod is hinged to the side wall of the U-shaped protective plate, the other end of the connecting rod is hinged to the lower end of the sliding block, one end of a contact rod is fixedly installed on both sides of the output shaft of the stamping structure, and the other end of the contact rod is in contact with the upper end of the sliding block.

[0008] Preferably, notches are provided on both sides of the U-shaped protective plate, one end of two groups of contact springs are fixedly mounted on the inner wall of the notch, a slide plate is fixedly mounted on the other end of the contact spring, and an extension plate is fixedly mounted on the side wall of the slide plate.

[0009] Preferably, one end of the return spring is fixedly connected to the inner wall of the slide groove, and the other end of the return spring is fixedly connected to the lower end of the sliding block.

[0010] Preferably, a positioning groove is opened on the surface of the fixing plate, an orientation rod is fixedly installed on the inner wall of the positioning groove, an orientation cylinder is slidably connected to the surface of the orientation rod, and the upper end of the orientation cylinder is fixedly connected to the lower end of the U-shaped protective plate.

[0011] Preferably, the movement distances of the U-shaped protective plate and the stamping structure are adapted to each other.

[0012] Compared with the prior art, the utility model provides a stamping forming device with a protective function, which has the following beneficial effects:

[0013] 1. The stamping forming device with a protective function is provided with a protective structure so that the stamping position can be conveniently shielded by the movement of the U-shaped protective plate. When the stamping structure moves downward for stamping, it will drive the sliding block to move. The downward movement of the sliding block drives the two sets of U-shaped protective plates to move relatively inward, thereby preventing iron filings from splashing out, and no manual operation is required, which improves the convenience of using the device.

[0014] 2. The stamping forming device with protective function is convenient for adapting to automobile parts of different thicknesses when processing them by setting notches, contact springs, slide plates, extension plates, etc. When the automobile parts are thinner, the stamping structure will go down a greater distance. At this time, the two sets of U-shaped protective plates will contact and squeeze, so that the extension plate moves inward through the extrusion contact elasticity, thereby improving the adaptability of the device.

One end of a contact rod 38 is fixedly installed on both sides of the output shaft of the stamping structure 2, and the other end of the contact rod 38 contacts the upper end of the sliding block 34. One end of a return spring 35 is fixedly connected to the inner wall of the slide groove 31, and the other end of the return spring 35 is fixedly connected to the lower end of the sliding block 34. A positioning groove 11 is opened on the surface of the fixed plate 6, and a directional rod 12 is fixedly installed on the inner wall of the positioning groove 11. A directional cylinder 13 is slidably connected to the surface of the directional rod 12, and the upper end of the directional cylinder 13 is fixedly connected to the lower end of the U-shaped protective plate 36. The moving distance of the U-shaped protective plate 36 and the stamping structure 2 are adapted.

[0022] Specifically, the protection structure 3 of the technical solution of the utility model includes: a slide groove 31, a slide rod 32, a sleeve 33, a sliding block 34, a return spring 35, a U-shaped protective plate 36, a connecting rod 37, and a contact rod 38.

[0023] In one embodiment of the utility model, a protective structure 3 is provided so as to conveniently shield the punched position by moving the U-shaped protective plate 36. The user can place the automobile parts in the middle of the placing table 5, and then start the punching structure 2 to punch. When the punching structure 2 moves downward to punch, it will drive the contact rod 38 of its side wall to move downward. The movement of the contact rod 38 drives the sliding block 34 at its lower end to move. At this time, the sliding block 34 slides on the surface of the sliding rod 32 through the sleeve 33 of its side wall. When the sleeve 33 moves downward, it will squeeze the return spring 35 at its lower end. The reset spring 35 is thereby placed in a compressed state, and the sliding block 34 moves downward, driving the connecting rod 37 of its side wall to move. The movement of the connecting rod 37 drives the two sets of U-shaped protective plates 36 hinged thereto to move relatively inward. The two sets of U-shaped protective plates 36 move relative to each other and close together to prevent iron filings from splashing out during stamping, and no manual operation is required, thereby improving the convenience of using the device. Subsequently, the stamping structure 2 no longer moves downward but is reset. At this time, the sleeve 33 and the sliding block 34 are driven to move upward for reset under the elastic force of the reset spring 35, thereby facilitating subsequent use.

By providing an adjustable and movable extension plate 10, it is convenient to adapt to automobile processing parts of different thicknesses when processing them. When the automobile processing parts are thinner, the stamping structure 2 will move downward a greater distance, so that the sliding block 34 moves downward more. At this time, the two groups of U-shaped protective plates 36 are in contact and squeezed. At this time, the two groups of extension plates 10 will be in contact and move inward under the thrust of the connecting rod 37. At this time, the extension plate 10 moves inward by squeezing the contact spring 8, so that the two groups of U-shaped protective plates 36 are still in a closed state, thereby improving the adaptability of the device.

[0025] During operation, the user can place the automobile parts in the middle of the placing table 5, and then start the stamping structure 2 to perform the stamping work. When the stamping structure 2 moves downward to perform the stamping, the contact rod 38 of the side wall thereof will be driven to move downward, and the movement of the contact rod 38 will drive the sliding block 34 at the lower end thereof to move. At this time, the sliding block 34 will slide on the surface of the sliding rod 32 through the sleeve 33 of the side wall thereof. When the sleeve 33 moves downward, the return spring 35 at the lower end thereof will be squeezed, so that the return spring 35 is in a compressed state, and the sliding block 34 moves downward to bring The connecting rod 37 of the side wall is moved, and the movement of the connecting rod 37 drives the two groups of U-shaped protective plates 36 hinged thereto to move relatively inward. At this time, the two groups of U-shaped protective plates 36 are in contact and squeezed, and then the two groups of extension plates 10 are in contact and move inward under the thrust of the connecting rod 37. At this time, the extension plate 10 moves inward by squeezing the contact spring 8, so that the two groups of U-shaped protective plates 36 are still in a closed state, thereby preventing iron filings from splashing out during stamping, and no manual operation is required, thereby improving the convenience of using the device.
