Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a rear upper swing arm punching device. Background Technology

[0002] Reference for rear upper control arm in automotive chassis components Figure 1 Since the rear upper control arm is an important safety structural component in the chassis, the product forming thinning rate of the rear upper control arm is required to be high. In order to meet the product thinning rate requirements, high-strength thick steel plates are usually selected, and a stamping process is adopted to form the product by feeding and stamping, and then punching off the excess waste material. The forming thinning is controlled within the waste area of ​​feeding. Therefore, the size after stamping will be larger than the required product (rear upper control arm) size. So after the product is formed, it is necessary to punch the product to remove the excess material. Since the part to be punched is located on the side of the rear upper control arm, and the excess material on both sides of the product needs to be punched off at the same time, the existing punching device is difficult to remove the excess material on the rear upper control arm. Utility Model Content

[0003] This invention addresses the shortcomings of existing punching devices, which struggle to remove excess material from the upper rear swing arm because the part to be punched is located on the side of the upper rear swing arm and the excess material on both sides of the product needs to be punched off simultaneously. This invention provides a punching device for punching excess material on both sides of the upper rear swing arm.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0005] A rear upper swing arm punching device includes an upper die and a lower die for placing a product. The lower die is provided with a positioning component for positioning the product and a punching component for punching excess material on the positioned product. The punching component includes two parallel and spaced punching blocks on the lower die for punching excess material on one side wall of the product, and a support block on the lower die for placing the product and exposing the excess material. A pushing component is provided between the upper die and the punching blocks to push the punching blocks toward the support block and punch the excess material off the product during the process of the upper and lower dies closing. The lower die is provided with a guiding component to guide the movement of the punching blocks when the pushing component pushes them, and a resetting component to drive the punching blocks back to their original position when the upper die moves away from the lower die.

[0006] Using the above scheme, the support block set on the lower die can be used to place the product. When the product is placed on the support block, the excess material on the product will be exposed outside the support block. When the upper die and the lower die are closed, the pushing component set between the upper die and the punching block will push the punching block to gradually approach the support block, so that the punching block will punch off the excess material on the product. When the upper die moves away from the lower die, the reset component will drive the punching block to reset, which will facilitate the punching of subsequent products.

[0007] Preferably, the pushing component includes two pushing blocks vertically spaced apart on the bottom surface of the upper die. The pushing blocks are provided with a pressing inclined surface that abuts against the punching block and pushes the punching block toward the support block when the upper die approaches the lower die. The punching block is provided with a mating inclined surface that cooperates with the pressing inclined surface on the pushing blocks.

[0008] Using the above scheme, the abutting inclined surface set on the push block can abut against the mating inclined surface on the punching block during the process of the upper and lower dies closing. After the two abut against each other, as the upper die continues to move, the push block will push the punching block to move closer to the support block, thereby punching off the excess material from the product.

[0009] Preferably, the guiding component includes a guide rail disposed on the top surface of the lower die and a slider disposed below the punching block that can cooperate with the guide rail.

[0010] Using the above solution, the slider located below the blanking block can move along the guide rail when the pushing component moves the blanking block, thereby guiding the movement of the blanking block and enabling the blanking block to more accurately cut off excess material from the product.

[0011] Preferably, the reset component includes a reset spring disposed on the lower die, which pushes the punching block to reset when the upper die moves away from the lower die.

[0012] Using the above solution, the return spring set on the lower die can push the punching block to return to its original position when the upper die moves away from the lower die, thereby facilitating the punching block to punch subsequent products.

[0013] Preferably, the lower die is provided with a sliding seat that can slide on the lower die, two punching blocks are arranged parallel and spaced apart on the top surface of the sliding seat, a moving block is protruding below the sliding seat, the lower die is provided with a sliding groove for the moving block to move in it, the two ends of the return spring abut against the side wall of the sliding groove and the moving block respectively, the lower die is provided with a mounting groove, the guide rail is arranged in the mounting groove, and the slider is fixedly arranged on the bottom surface of the sliding seat.

[0014] By adopting the above scheme, a sliding seat is set on the lower die and two punching blocks are set parallel and spaced on the top surface of the sliding seat, so that the two punching blocks move more synchronously when the upper die and the lower die are closed, thereby facilitating the two punching blocks to punch off the excess material located on both sides of the product from the product at the same time.

[0015] Preferably, the positioning component includes a positioning pin provided on the lower mold and a positioning hole provided on the product into which the positioning pin can be inserted.

[0016] Using the above solution, the positioning pins set on the lower die can be inserted into the positioning holes on the product when the product is placed on the lower die, thereby positioning the product and reducing the probability of the product shifting during punching.

[0017] Preferably, the support block is provided with a slot, and a mounting block is provided in the slot. The positioning pin is provided on the mounting block, and the side wall of the slot is provided with a component to prevent the mounting block from falling out of the slot.

[0018] By adopting the above solution, the positioning pin is set on the mounting block and the mounting block is restricted from being dislodged from the slot by the anti-dislodgement component, so that the positioning pin is detachably set on the support block. At the same time, when the size of the product changes, the mounting block can also be removed from the support block and replaced with another mounting block with a different positioning pin position than the removed mounting block. This allows the positioning pin on the newly replaced mounting block to position the product with the changed size, thereby improving the applicability of the punching device.

[0019] Preferably, the anti-dislodgement component includes an elastic hook provided on the inner wall of the slot, and an avoidance groove provided on the inner wall of the slot to avoid the deformation of the elastic hook when the mounting block is inserted into the slot, wherein the elastic hook is provided at the end of the avoidance groove away from the bottom of the slot.

[0020] Using the above solution, the elastic hook set in the clearance groove can position the mounting block when it is inserted to the bottom of the slot, preventing the mounting block from coming out of the slot. At the same time, the elastic hook restricts the mounting block from coming out of the slot, so that the operator does not need to use other tools when assembling or disassembling the mounting block, thus making it easier for the operator to assemble or disassemble the mounting block.

[0021] Preferably, the elastic hook is provided with an induction bevel that causes the elastic hook to automatically deform when the mounting block is inserted into the slot.

[0022] Using the above scheme, the guide slope set on the elastic hook can abut against the surface of the mounting block when the mounting block is inserted into the slot. As the mounting block continues to go deeper, the mounting block will squeeze the guide slope, causing the elastic hook to deform. When the mounting block moves to below the elastic hook, the elastic hook will reset due to its own elastic deformation, thereby preventing the mounting block from coming out of the slot.

[0023] This utility model has significant technical effects due to the adoption of the above technical solutions: the support block set on the lower die can be used to place the product, and when the product is placed on the support block, the excess material on the product will be exposed outside the support block. When the upper die and the lower die are closed, the pushing component set between the upper die and the punching block will push the punching block to gradually approach the support block, so that the punching block will punch off the excess material on the product. When the upper die moves away from the lower die, the reset component will drive the punching block to reset, which facilitates the punching of subsequent products. Attached Figure Description
