Description

Technical Field

[0001] The present invention relates to the technical field of automotive part processing, and particularly relates to an automatic stamping die for automotive parts. Background Art

[0002] A stamping die is a special process equipment for processing metal or non-metal materials into parts or semi-finished products in cold stamping processing. Stamping is a metal processing method that applies pressure to the material using a die installed on a press at room temperature, causing it to separate or plastically deform to obtain the required parts.

[0003] Chinese Patent Document CN214023175U discloses an automatic demoulding stamping die for automotive parts. A supporting plate is installed in the cavity of the lower die base through a spring, and limiting plates connected to the cavity through springs are arranged on both left and right sides of the supporting plate. The side of the limiting plate close to the supporting plate is an inclined structure, and the bottom ends on both left and right sides of the supporting plate are inclined structures. During use, the supporting plate moves downward due to the pressure of the press and squeezes the limiting plates to both left and right sides. After stamping, the springs of the limiting plates rebound to extrude the supporting plate upward, and the springs of the supporting plate also rebound simultaneously, thereby ejecting the workpiece to achieve automatic demoulding. The demoulding is fast, there is no need to use tools to pry, and the structure is simple and easy to use; on the lower die base, two limiting members are connected through springs on the left and right, which can limit the workpiece on the lower die base to prevent waste products caused by stamping failure due to placement deviation.

[0004] However, the size models of the upper and lower die bases of the above-mentioned die are fixed and cannot be replaced, resulting in the die being able to only process automotive parts of a single shape, restricting the scope of use of the die. Therefore, we propose an automatic stamping die for automotive parts. Summary of the Invention

[0038] The demoulding mechanism 6 includes a knockout rod 61, a fixed rod 62, a second spring 63, a control rod 64, a suspension rod 65, a resisting block 66 and a positioning assembly 67. The knockout rod 61 movably penetrates through the stamping table 2, the first template 8 and the lower die 9. A forming groove is opened on the top of the lower die 9. A cavity is opened on the bottom of the stamping table 2. A fixed rod 62 is fixedly installed on the top of the mounting plate 1. The knockout rod 61 is movably sleeved on the fixed rod 62. A second spring 63 is sleeved on the fixed rod 62. The two ends of the second spring 63 are fixedly connected to the knockout rod 61 and the mounting plate 1 respectively. A through groove 7 communicating with the cavity is opened on the front side of the stamping table 2. A control rod 64 penetrating through the through groove 7 is fixedly installed on the outer surface of the knockout rod 61. A suspension rod 65 is fixedly installed on the outer surface of the knockout rod 61. A resisting block 66 is fixedly installed at one end of the suspension rod 65. A positioning assembly 67 is arranged on the stamping table 2.

[0039] The positioning component 67 includes a through rod 671, a positioning block 672, a second magnet 673, and a grip 674. The through rod 671 movably penetrates through the front side of the stamping table 2. One end of the through rod 671 is fixedly installed with the positioning block 672, and the other end of the through rod 671 is fixedly installed with the second magnet 673. The second magnet 673 is adsorbed on the outer surface of the front side of the stamping table 2. The grip 674 is fixedly installed on the second magnet 673. By the combined use of the demoulding mechanism 6 and the through groove 7, during the forming process of automotive parts on the lower die 9, the automotive parts can be automatically ejected and demoulded, facilitating blanking. At the same time, when disassembling and assembling the first template 8 and the lower die 9, the ejector rod 61 can be completely retracted into the stamping table 2 to avoid spatial interference with the first template 8 and the lower die 9.

[0040] Working principle: During stamping, place the workpiece in the forming groove in the lower die 9, control the free end of the hydraulic rod 11 to extend, drive the suspension plate 12 to move downward, drive the stamping head 15 on the second template 14 to stamp the workpiece into shape, and the ejector rod 61 will also be pressed down to be flush with the inner bottom of the forming groove. When the ejector rod 61 moves downward, it will compress the second spring 63 on the fixed rod 62, and the ejector rod 61 will drive the abutting block 66 on the suspension rod 65 to just abut against the top of the positioning block 672 to prevent the ejector rod 61 from continuing to move downward, ensuring the flatness of the inner bottom of the forming groove. After stamping, the hydraulic rod 11 drives the suspension plate 12, the second template 14, and the stamping head 15 to move upward and reset. The ejector rod 61 automatically ejects the workpiece in the forming groove under the rebounding action of the second spring 63 to complete blanking. When different lower dies 9 and stamping heads 15 need to be replaced, for the first limiting mechanism 4, first pull out the through rod 671 and the positioning block 672 outward through the grip 674, so that the second magnet 673 no longer adsorbs the stamping table 2, and the positioning block 672 is misaligned with the abutting block 66. Hold the control rod 64 and move it downward to drive the ejector rod 61 to retract into the stamping table 2 and no longer penetrate through the first template 8 and the lower die 9. Then, the two groups of metal limiting plates 42 can be rotated by the two groups of handles 43, and the two groups of metal limiting plates 42 are separated from the adsorption of each first magnet 45 until the two groups of metal limiting plates 42 no longer block the first template 8, and then the first template 8 can be slid out from the first U-shaped sleeve 3 together with the lower die 9 and replaced. For the second limiting mechanism 5, toggle the two groups of toggle rods 54 to drive the two groups of sliders 52 to slide in the respective chutes 51 and compress the respective first springs 53, driving the two groups of movable limiting plates 55 to move to both sides until they no longer block the second template 14, and then the second template 14 can be slid out from the second U-shaped sleeve 13 together with the stamping head 15 and replaced.

[0041] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the gist of the present invention.
