Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to an automobile parts stamping die. Background Art

[0002] In the current diversified automobile manufacturing field, there are many types of automobile parts, but they can be roughly divided into two categories: metal parts and plastic parts. It is worth noting that in the processing and manufacturing of metal parts, a large number of parts need to be produced according to the stamping process. This processing method not only ensures the accuracy and strength of the parts, but also greatly improves production efficiency and reduces production costs. It plays an important role in improving the overall performance and quality of the car.

[0003] With the rapid progress of society and the booming economy, stamping dies, as a key special process equipment, play a vital role in the cold stamping process. It can accurately process various materials, whether metal or non-metal, into required parts or semi-finished products at room temperature. This process equipment is widely referred to as cold stamping dies in the industry, commonly known as cold stamping dies.

[0004] Stamping technology, specifically, is to apply precise and strong pressure to the raw materials through a carefully installed mold on a press at room temperature. During this process, the material will separate or undergo plastic deformation, and then be formed into the required parts according to the design requirements. This pressure processing method is widely used in industrial production due to its high efficiency and precision. Although the current existing technology can realize the stamping process of automotive parts during use, it uses a manipulator or ejection tool. During the demolding process, due to the compressive stress between the automotive parts and the mold, direct demolding may damage the product. For this reason, we propose a stamping mold for automotive parts. Summary of the invention

[0043] From the above, we can know that:

[0044] The present invention is directed to the following technical problem: Although the existing technology can realize the stamping process of automobile parts during use, the product may be damaged if the mold is directly demolded due to the compressive stress between the automobile parts and the mold by means of a manipulator or an ejection tool during demolding; the technical solutions of the above embodiments are adopted.

[0046] During use, the test piece is placed in the bottom die, and then the hydraulic cylinder 4 is started. The output end of the hydraulic cylinder 4 pushes the U-shaped connecting plate 5 to move downward until the punch head performs a punching operation on the test piece. At the same time, the first motor 6 is started, and the output end of the first motor 6 drives the first pulley 7 to rotate, so that the second pulley 9 and the second circulating roller 16 rotate synchronously. When the second circulating roller 16 contacts the second contact roller 14, the second circulating roller 16 pushes the second contact roller 14 to move downward, and then the second contact roller 14 drives the vertical guide rail 11 to move downward along the inner side of the vertical track groove 10, so that the vertical guide rail 11 drives the punch head to perform a secondary punching operation on the test piece.

[0047] When demolding is performed after stamping is completed, the second motor 21 is started, and the output end of the second motor 21 drives the driving gear 22 to engage the force gear 23 to rotate, so that the force gear 23 drives the matching vibration rod 24 to rotate synchronously, and then the electromagnet balls 36 are energized respectively, so that a mutual attraction force or a mutual repulsion force is generated between the two electromagnet balls 36, and by continuously changing the magnetic poles of the electromagnet balls 36, the matching vibration rod 24 drives the vibration head 37 to reciprocate and contact with the bottom mold to generate micro-vibration, gradually eliminating the compressive stress between the product and the bottom mold, and finally the product is smoothly demolded with the help of a demolding ejection tool or a manipulator.

[0048] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0049] 1. The structural design of the pressure mechanism and the auxiliary mechanism of the present invention makes it easy for the device to move the punch head vertically, so that the punching process of the product can be realized in cooperation with the bottom mold, and secondary pressure or pressure relief can be performed after the initial punching, which speeds up the work efficiency and improves the product's factory yield.
