Description

Technical Field

[0001] The utility model relates to the technical field of drawing dies, in particular to a drawing die structure. Background Art

[0002] The drawing die is a process of punching or drawing the sheet into a specified shape through the cooperation between the upper die and the lower die, thereby completing the processing of the sheet.

[0003] At present, when most drawing dies are used, the staff will first place the plate on the top of the lower die, and then press down with the upper die, and cooperate with the lower die to process and shape the plate. However, due to the lack of a limiting structure between the upper die and the lower die, the plate may be offset when the upper die is pressed down, resulting in deviations in the size of the plate after forming, which is inconsistent with the preset shape, resulting in defects in the stamped plate. Therefore, it is necessary to design a drawing die structure that can effectively limit the plate to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0020] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0021] In the description of this technology, it should also be noted that, unless otherwise specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this technology based on the specific circumstances.

[0022] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0023] See also Figure 1-3The utility model includes a first mounting plate 01, a second mounting plate 012, an upper mold 022, a lower mold 041 and a plate body 04. The lower mold 041 is mounted on the top of the second mounting plate 012. First support columns 011 are provided at the four corners of the opposite surfaces of the first mounting plate 01 and the second mounting plate 012. The four corners of the top of the second mounting plate 012 are connected to the third mounting plate 014 through second support columns 013. A stamping assembly is provided at the bottom end of the third mounting plate 014. The stamping assembly includes a telescopic mechanism 02 and a fourth mounting plate 021. The upper mold 022 is mounted on the bottom end surface of the fourth mounting plate 021; a first limiting assembly is provided at the top of the second mounting plate 012 near the front and back sides of the upper mold 022, and a second limiting assembly is provided at the top of the second mounting plate 012 near both sides of the upper mold 022.

[0024] There are several telescopic mechanisms 02 and they are all installed at the bottom end of the third mounting plate 014. The top surface of the fourth mounting plate 021 is connected to the output end of the telescopic mechanism 02. The position of the upper mold 022 corresponds to the lower mold 041. The telescopic mechanism 02 is an electric cylinder or a hydraulic rod. The first mounting plate 01, the second mounting plate 012 and the third mounting plate 014 are fixedly connected by the first support column 011 and the second support column 013.

[0025] When stamping is required, the sheet body 04 is first placed on the top of the lower mold 041, and then the telescopic mechanism 02 is started. The telescopic mechanism 02 is used to drive the fourth mounting plate 021 and the upper mold 022 to move downward, thereby coordinating the groove at the bottom of the upper mold 022 and the curved surface at the top of the lower mold 041 to stamp the sheet body 04 into shape.

[0026] See also Figure 1 and Figure 3 In this embodiment, in order to better limit the plate body 04, the first limiting component includes a vertical rod 05, a slide groove 051, a splint 052, a slider 053 and a threaded rod 054. There are four vertical rods 05 and they are respectively arranged at the top of the second mounting plate 012 close to the front and back of the lower mold 041. The slide groove 051 runs through the front of the vertical rod 05; the slider 053 slides and is engaged in the slide groove 051, the threaded rod 054 threads through the slider 053 and is perpendicular to the slider 053, the splint 052 is designed as a long strip structure and is connected to the end of the threaded rod 054 close to the lower mold 041 through a bearing, and the bottom end of the vertical rod 05 is fixedly connected to the second mounting plate 012.

[0027] When the plate body 04 is placed on the top of the support platform 033 and the top of the lower mold 041, grab the threaded rod 054 and drive the slider 053 to slide in the slide groove 051, so that the center position of the clamping plate 052 is aligned with the two sides of the plate body 04, and rotate the threaded rod 054 to drive the clamping plate 052 to approach the plate body 04 until it contacts the plate body 04. Through the cooperation between the four clamping plates 052, the plate body 04 placed on the lower mold 041 can be effectively limited to prevent it from shifting.

[0028] See also Figure 1 and Figure 2 It should be noted that, in order to better limit the support platform 033 and facilitate the support of the plate body 04, the second limiting assembly includes the support platform 033, the limiting cylinder 03, the first limiting rod 031, the second limiting rod 032 and the limiting plate 034. There are two second limiting rods 032 and both are inserted through the second mounting plate 012 near the positions on both sides of the lower mold 041. The support platform 033 is set at the top of the second limiting rod 032;

[0029] The limiting plate 034 is arranged between the bottom ends of the two second limiting rods 032, the first limiting rod 031 is arranged at the central position of the bottom end of the limiting plate 034, and the limiting cylinder 03 is arranged at the top of the first mounting plate 01 corresponding to the first limiting rod 031. The interior of the limiting cylinder 03 is a hollow structure and the top is open. The first limiting rod 031 is movably inserted in the limiting cylinder 03, and a spring is arranged between the inner cavity of the limiting cylinder 03 and the first limiting rod 031.

[0030] When the upper mold 022 is pressed down, it will simultaneously press down the plate body 04 and the support platform 033. The support platform 033 will move downward when under pressure, and at the same time drive the second limit rod 032 and the limit plate 034 to move downward, and drive the first limit rod 031 downward through the limit plate 034, so that the first limit rod 031 moves downward inside the limit tube 03, causing compression on the spring. After the upper mold 022 returns to its position, the support platform 033 will be driven back to its original position by the rebound of the spring. The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of the claims of the present invention.
