Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bending and stamping, and particularly relates to a downward forming stamping die. Background Art
[0002] In the field of stamping part processing, bending the stamping part is a common process. Mainly, an external force is applied to the stamping part by a stamping die or the like to cause it to bend and deform, so as to obtain the required fillet and bending angle.
[0003] In the existing general stamping die, when it is necessary to bend the stamping part by 90 degrees, it is usually necessary to first bend the stamping part by 45 degrees, and then bend the remaining 45 degrees of the stamping part, that is, it is implemented step by step through two dies, so as to reduce the occurrence of situations such as material turning, distortion or dimensional error. However, this method increases the cost of the die and also increases the processing time. Summary of the Utility Model
[0004] The utility model provides a downward forming stamping die to solve the above technical problems.
[0005] The solution adopted by the utility model to achieve its technical effect is as follows:
[0006] The downward forming stamping die includes a lower support mechanism and an upper stamping mechanism; the lower support mechanism includes a lower support member; the upper stamping mechanism includes an upper stamping member; on the side of the bottom surface of the upper stamping member facing the lower support member, a first bending point and a second bending point are respectively arranged from bottom to top; the horizontal distance between the first bending point and the support member is greater than the horizontal distance between the second bending point and the support member.
[0007] Preferably, a safety groove is arranged on the side of the lower support member facing the upper stamping member.
[0008] Preferably, a clearance groove is arranged between the first bending point and the second bending point.
[0009] Preferably, a bending groove is arranged on the side of the bottom surface of the upper stamping member facing the lower support member; a vertical and smooth bending surface is arranged between the bending groove and the second bending point.
[0010] Preferably, the lower support mechanism further includes a lower die; the lower support member is arranged in the lower die; a product bending cavity is arranged in the lower die.
[0011] Preferably, the upper stamping mechanism further includes an upper die; the upper stamping member is slidably arranged in the upper die; the bottom of the upper stamping member can slide into the product bending cavity.
[0012] The beneficial effects of the present utility model are as follows: There are a first bending point and a second bending point. First, the area near the edge of the product is stamped through the first bending point, which facilitates quickly bending the product to a certain angle. Then, the area near the bending corner of the product is stamped through the second bending point to bend the product to 90 degrees. The present utility model can bend the product into 90 degrees at one time. During the bending process of the product, the position of the stamping pressure changes, avoiding the phenomena of product turnover and distortion that may be caused by bending the product into 90 degrees in a one-time vertical manner. At the same time, before the product is bent to 90 degrees, the stressed part is close to the corner. With the same punching pressure, the resistance is greater, that is, the bending speed is slowed down before bending forming, ensuring the smoothness of the final bending step of the product and avoiding errors in the bending angle. Thus, it can be seen that the present utility model can effectively reduce the mold cost while improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. It should be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. When an element is referred to as being "fixedly connected to" another element, it can be connected by common fixed connection methods such as welding, bolt connection or gluing connection.
[0018] Please refer to Figures 1-3, in a preferred embodiment of the present utility model, a downward forming stamping die is disclosed, which includes a lower support mechanism and an upper stamping mechanism; the lower support mechanism includes a lower support member 1; the upper stamping mechanism includes an upper stamping member 2; on the side of the bottom surface of the upper stamping member 2 facing the lower support member 1, a first bending point 3 and a second bending point 4 are respectively arranged from bottom to top; the horizontal distance between the first bending point 3 and the support member 1 is greater than the horizontal distance between the second bending point 4 and the support member 1.
[0019] Specifically, a safety groove 5 is arranged on the side of the lower support member 1 facing the upper stamping member.
[0020] Specifically, a clearance groove 6 is arranged between the first bending point 3 and the second bending point 4.
[0021] Specifically, a bending groove 7 is arranged on the side of the bottom surface of the upper stamping member 2 facing the lower support member 1; a vertically smooth bending surface 8 is arranged between the bending groove 7 and the second bending point 4.
[0022] Specifically, the lower support mechanism further includes a lower die 9; the lower support member 1 is arranged in the lower die 9; a product bending cavity is arranged in the lower die 9.
[0023] Specifically, the upper stamping mechanism further includes an upper die 10; the upper stamping member 2 is slidably arranged in the upper die 10; the bottom of the upper stamping member 2 can slide into the product bending cavity.
[0024] Working process: The upper stamping member 2 presses downwards, the first bending point 3 touches the product first, and the upper stamping member 2 continuously presses down and bends the product through the first bending point 3 until the product is bent at a certain angle, then the first bending point 3 disengages from the product, and the second bending point 4 with a relatively closer horizontal distance and closer to the product bending part touches the product. After that, the upper stamping member 2 presses down and bends the product through the second bending point 4 until the product is bent 90 degrees. During the bending process, due to the clearance groove 6 arranged between the first bending point 3 and the second bending point 4, the product will not contact other parts of the upper stamping member 2 before being pressed and bent by the first bending point 3 until it disengages; due to the vertically smooth bending surface 8 arranged between the second bending point 4 and the bending groove 7, after the product is touched and pressed and bent by the second bending point 4, the bent part of the product will gradually contact the bending surface 8, that is, the pressure area received gradually increases until the bending surface 8 is completely attached to the outer side of the bent part of the product and the bending groove is bent and wrapped to fit on the outer side of the bent angle of the bent part of the product. At this time, the bent part of the product is exactly bent to 90 degrees.
[0025] Particularly, the upper stamping member 2 is configured with a pressure device for controlling its lifting and lowering.
[0026] As can be seen from the above description, the utility model can effectively reduce the mold cost while improving the work efficiency.
