Description

Technical Field

[0001] The utility model relates to the technical field of punching dies, in particular to an inclined surface punching die structure for a lower guard mounting plate bracket. Background Art

[0002] The lower guard mounting plate bracket is one of the main brackets for installing and fixing car seats. The lower guard mounting plate bracket of a passenger car has many functions on the seat and has many holes. At the same time, the shape of the bracket is irregular, so that the holes are not on the same plane.

[0003] The original stamping process is: blanking, forming, and four punchings (all four sides of the product need to be punched). In this way, the product will be deformed after multiple punching operations, causing the round hole to become an elliptical hole. At the same time, multiple punching will lead to an unsightly appearance of the product. The mold cost investment is relatively large, and the product punching and forming requires multiple mold changes, which is time-consuming and labor-intensive, and seriously affects the production efficiency of the product.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1: Please refer to Figures 1 to 5 :

[0032] The utility model proposes a lower guard mounting plate bracket inclined surface punching die structure, comprising: a lower die base 1; an upper die base 2 is arranged on the upper part of the lower die base 1; a workpiece positioning seat 102 is installed in the middle of the upper end surface of the lower die base 1, and a lower guard mounting plate bracket member 3 is placed on the upper part of the workpiece positioning seat 102; a side punch driving slider 4 is slidably connected to the left and right sides of the upper end surface of the lower die base 1, and the two side punch driving sliders 4 are symmetrically distributed, and side punches are installed at the opposite ends of the two side punch driving sliders 4; two slides 104 are symmetrically installed on the rear side of the upper end surface of the lower die base 1, and each slide 104 is slidably connected to a rear punch driving slider 5, and a rear punch is installed on the front side of the rear punch driving slider 5, which is used for punching the rear of the lower guard mounting plate bracket member 3.

[0033] A vertical guide column 101 is provided at the four corners of the upper end surface of the lower die base 1; two sliding guide blocks 103 are installed on the left and right sides of the upper end surface of the lower die base 1 in a front-to-back symmetrical shape, and each front-to-back adjacent two sliding guide blocks 103 are slidably connected to a side punch driving slider 4, and the setting of the sliding guide block 103 is used to guide the side punch driving slider 4.

[0034] Bushings 201 are fixedly embedded at the four corners of the upper die base 2. The four bushings 201 are used for sliding connection with the four vertical guide pillars 101, so that the upper die base 2 and the lower die base 1 are more accurately aligned.

[0035] A countersunk hole 208 is provided on the upper end surface of the upper mold base 2, and a T-shaped guide slide column 205 is slidably connected inside the countersunk hole 208; a clamping block 202 is fixedly connected to the lower end of the T-shaped guide slide column 205, and the clamping block 202 is used to clamp and position the lower guard mounting plate bracket 3.

[0036] Two fixed blocks 206 are fixedly installed at the bottom of the upper die base 2, and an upper punch 207 is fixedly installed inside the fixed block 206 on the right, and the upper punch 207 passes through the clamping block 202; the T-shaped guide slide column 205 passes through the fixed block 206, and is used to punch holes on the upper surface of the lower guard mounting plate bracket 3 through the setting of the upper punch 207.

[0037] Three side wedges 203 are evenly fixedly installed on the left and right sides of the bottom of the upper die base 2, and the inclined surfaces of the side wedges 203 on the left and right sides of the bottom of the upper die base 2 are respectively in contact with the inclined surfaces of the two side punch driving sliders 4. Through the side wedges 203 and the inclined surfaces on the side punch driving sliders 4, the side wedges 203 on both sides will move in the opposite direction (inward direction) with the two side punch driving sliders 4 during the downward movement.

[0038] Two rear wedge blocks 204 are installed on the rear side of the bottom of the upper die base 2 in a left-right symmetrical shape, and the inclined surfaces of the two rear wedge blocks 204 are in contact with the inclined surfaces of the two rear punch driving sliders 5 respectively. Through the inclined surfaces on the rear wedge blocks 204 and the rear punch driving sliders 5, the two rear wedge blocks 204 will move forward simultaneously with the two rear punch driving sliders 5 during the downward movement.

[0039] Embodiment 2, based on embodiment 1, as Figure 1 and Figure 5 As shown, the vertical cross-section of the T-shaped guide slide column 205 is T-shaped, and a spring (not shown in the figure) is sleeved on the outside of each T-shaped guide slide column 205 between the clamping block 202 and the fixed block 206, so that the clamping block 202 has better elasticity, so that the clamping block 202 has better clamping force, so that when the lower guard mounting plate bracket 3 is positioned, it can be quickly positioned without cumbersome clamps.

[0040] The working principle of this embodiment is as follows: when in use, the lower die base 1 is fixedly installed on the workbench of the punch press, and the upper die base 2 is fixedly installed on the slider of the punch press. When punching the lower guard mounting plate bracket 3, first place the lower guard mounting plate bracket 3 on the workpiece positioning seat 102, and then control the slider of the punch press to move the upper die base 2 downward, and then the bottom of the clamping block 202 first contacts the top of the lower guard mounting plate bracket 3, and then the slider of the punch press continues to move downward with the upper die base 2, and under the action of the external spring force of the T-shaped guide slide column 205, the clamping block 202 presses the lower guard mounting plate bracket 3, and then the upper die base 2 moves downward with the fixed block 206 and the upper punch 207, and the upper surface of the lower guard mounting plate bracket 3 is punched by the downward moving upper punch 207.

[0041] During the downward movement of the upper die base 2, the six side wedge blocks 203 and the two rear wedge blocks 204 move downward. Through the six side wedge blocks 203 moving downward, the two side punches drive the sliders 4 to move inward with the side punches at the same time under the action of the inclined surface, thereby punching the left and right sides of the lower guard mounting plate bracket 3. At the same time, through the two rear wedge blocks 204 moving downward, the two rear punches drive the sliders 5 to move forward with the rear punches under the action of the inclined surface, thereby punching the rear side of the lower guard mounting plate bracket 3. In this way, the upper surface, left side, right side and rear side of the lower guard mounting plate bracket 3 can be punched at the same time, avoiding product deformation caused by multiple punching operations.
