Description

TECHNICAL FIELD

[0001] The utility model relates to part shaping technical field, concretely relates to a double contact part side push type shaping die. BACKGROUND

[0002] Cold stamping is a metal processing technology, which applies external force to metal sheet at room temperature to make it plastically deform, thereby obtaining parts with desired shape and size. This process has the advantages of high production efficiency, high material utilization rate, low manufacturing cost, etc., and has been widely used in manufacturing industry. However, during cold stamping, due to factors such as elastic recovery of materials, wear of dies, stamping speed, stamping force, and internal stress of materials, the parts after stamping often bend upward or downward to varying degrees. This bending not only affects the appearance quality of the parts, but also may affect their performance.

[0003] To solve this problem, stamping dies are needed to shape metal parts. Stamping dies are indispensable tools in cold stamping process, which determine the final shape and size of the parts. For example, the utility model patent with the authorization announcement number CN210138988U discloses a shaping stamping die, which includes an upper die holder and a lower die holder. The upper die holder is fixed with a fixed plate below, and the fixed plate is vertically fixed with a shaping punch in the middle. The shaping punch is fixed with guide columns at the bottom of the fixed plate. The lower die holder is fixed with a concave die plate, and the concave die plate is fixed with a concave die shaping insert at the center corresponding to the position of the shaping punch. The concave die shaping insert is fixed with a positioning shaping block, and the concave die plate has holes corresponding to the positions of the guide columns. The bottom surface of the shaping punch is inclined, and the side wall of the positioning shaping block is inclined inward from top to bottom. This die can effectively improve the safety of the die and the shaping of the stamped parts, and prolong the service life of the parts.

[0004] It can be seen that the above-mentioned die can perform stamping shaping on metal parts in the up-down direction, but for the side surface, especially for metal parts that need to be shaped on both sides, if the above-mentioned die is used for shaping, the metal part needs to be first stamped and shaped on one side in the up-down direction, and then the other side of the metal part needs to be adjusted for stamping and shaping. The whole process is relatively cumbersome. UTILITY MODEL CONTENTS

[0005] The utility model provides a double contact part side push type shaping die to solve the technical problem that the process is cumbersome and not easy to realize when the double contact part is stamped and shaped in the prior art.

[0006] To solve the above-mentioned problems, the double contact part side push type shaping die provided by the utility model adopts the following technical scheme:

[0007] A double-contact part side-push shaping die comprises a lower die base and an upper die base that can move relative to each other, a punch being mounted on the upper die base, and a placement position for placing the part on the lower die base, with sliders being arranged on both the left and right sides of the placement position, with the area between the two sliders being defined as the inner side. The upper die base also has inserts corresponding to the outer sides of the two sliders, respectively. When the lower die base and the upper die base approach each other, the two inserts respectively contact the outer sides of the two sliders, causing the two sliders to move inward to press the two sides of the part for leveling.

[0008] It also includes a reset component, which is used to drive the two slide blocks to reset when the lower die base and the upper die base are relatively far apart.

[0009] The double-contact part side-push shaping die provided by the utility model has the following beneficial effects: when the upper die base and the lower die base move relative to each other, the distance between the two inserts and the sliders gradually decreases until they respectively abut against the outer sides of the two sliders. The two sliders can move inward to perform side-push pressure contact on both sides of the part. Both sides of the part are forced to be leveled at the same time, and the punch abuts against the upper side of the part until the upper die base and the lower die base move to the set position. At this time, the shaping is completed, the upper die base and the lower die base move away from each other, and the two sliders are driven by the reset assembly to reset to the initial state. At this time, the part can be easily removed from the die;

[0010] The whole process only requires one operation to place the parts, and the side-push pressure-contact shaping on both sides of the parts can be completed, which effectively solves the technical problem of complicated and difficult-to-implement stamping process of double-contact parts in the existing technology.

[0011] Furthermore, an upper pad is fixed to the lower side of the upper die base, an upper clamp is fixed to the lower side of the upper pad, and the punch is fixed to the middle of the upper clamp in an interference fit manner.

[0012] Furthermore, two pressing blocks located on both sides of the punch are fixed to the lower side of the upper clamping plate, and the two pressing blocks are used to assist in clamping the punch, and one of the inserting blades is fixed to the outer side of each of the two pressing blocks.

[0013] Furthermore, the upper die base, the upper pad and the upper clamping plate are fixed by positioning pins and screws, the pressing block is fixed to the upper clamping plate by positioning pins and screws, and the insert is fixed to the pressing block by screws.

[0014] Furthermore, the reset assembly is divided into two groups, and the two groups of reset assemblies are respectively connected to the two sliders. Each group of reset assemblies includes a fixing frame fixed on the lower mold base and located outside the slider. The fixing frame is connected to the slider through a connecting rod, and the connecting rod is provided with a spring for driving the slider to reset.

[0015] Furthermore, a lower pad is fixed to the upper side of the lower die base by screws and positioning pins, a lower clamp is fixed to the upper side of the lower pad by screws and positioning pins, and the reset assembly is fixed to the lower clamp.

[0016] Further, the number of the lower clamping plates is two, and the middle part of the two lower clamping plates is clamped with a positioning block, and the positioning block is provided with the placing position.

[0017] Further, the lower die seat is fixed with a guide column, and the upper die seat is guided and installed on the guide column, so that the upper die seat moves in the up-down direction. BRIEF DESCRIPTION OF DRAWINGS
