Description

Technical Field

[0001] The present invention relates to a powder forming machine, and more particularly to a stopper layout system suitable for a powder forming machine. Background Art

[0002] Since the powder forming machine can press parts with high precision and good surface finish at one time, and has the characteristics of wide application range, high production efficiency and high material utilization rate, it has been deeply favored by enterprises and has now been widely used in the pressing of various powder products such as metals, ceramics, and bakelites. Moreover, the shapes of the pressed products are becoming more and more complex, and parts with multi-step shapes, parts with through holes in the middle, and parts with internal stepped blind holes in the middle can all be processed.

[0003] The function of the stoppers of the lower five-punch mechanism of the powder forming machine is to limit the forming positions of each punch plate. Different punch plates have different forming positions, and a single punch plate also has different forming positions during the forming process. The positioning accuracy of each forming position has a crucial impact on the accuracy, yield rate and production efficiency of the product. In addition, the punch plate has a certain self-weight, and the stoppers must have corresponding strength to support it; at the same time, to ensure the positioning accuracy, the support of the stoppers for the punch plate must be centrosymmetric; considering cost and usage conditions, on the basis of meeting the mechanical properties, the size of the punch plate should be as small as possible. In addition, a stopper forming adjustment device is required to adjust the forming height position of the stopper in the reciprocating movement direction of the punch plate.

[0004] In the technical solution of the lower four-punch mechanism of the existing powder forming machine, the two pairs of stoppers are symmetrically arranged front, back, left and right. However, in the design of the lower five-punch mechanism, there is one more punch plate, and at least one more pair of stopper bearing points needs to be added. How to reasonably arrange the stoppers and the stopper forming adjustment device in a limited space is the difficulty in the design of the lower five-punch mechanism.

[0005] Therefore, the technical personnel in this field are committed to developing a stopper dislocation layout system for the powder forming machine to realize the layout of the stoppers and the stopper forming adjustment device with a relatively simple and practical structure after adding one more punch plate. Summary of the Invention

[0006] In view of the problems existing in the prior art, the present invention proposes a new stopper layout system for a powder forming machine.

[0007] The technical solution of the present invention is as follows:

[0008] A stopper layout system for a powder forming machine includes a bottom plate, side stoppers, a center stopper and a stopper forming adjustment device; the side stoppers, the center stopper and the stopper forming adjustment device are all installed on the bottom plate; the center stopper is arranged at a position close to the geometric center of the bottom plate, and the side stoppers are arranged around the center stopper;

[0009] Furthermore, the block forming adjustment device corresponding to the central block is arranged within the angle range between the geometric center connection line of a group of symmetrically arranged side blocks and the geometric center connection line of another group of symmetrically arranged side blocks;

[0010] Furthermore, the side blocks are two-down punch blocks and three-down punch blocks, and the center block is a four-down punch block; the block forming adjustment device corresponding to the four-down punch block is arranged within the range of the included angle between the geometric center connecting line of a group of symmetrically arranged two-down punch blocks and the geometric center connecting line of a group of symmetrically arranged three-down punch blocks; the block forming adjustment device corresponding to the two-down punch block and the three-down punch is arranged in a direction parallel to the geometric center connecting line of a group of three-down punch blocks;

[0011] Further, the side blocks are two-down punch blocks and three-down punch blocks, and the center block is a four-down punch block; a geometric center connection line of a group of symmetrically arranged two-down punch blocks is at a vertical angle to a geometric center connection line of a group of symmetrically arranged three-down punch blocks, and the block forming adjustment device corresponding to the four-down punch blocks is set within the aforementioned vertical angle range; the block forming adjustment device corresponding to the two-down punch block and the three-down punch is set in a direction parallel to the geometric center connection line of a group of three-down punch blocks;

[0012] Furthermore, there are two two-down punch blocks, which are symmetrically arranged on both sides of the four-down punch block; there are two three-down punch blocks, which are symmetrically arranged on both sides of the four-down punch block; two two-down punch blocks and two three-down punch blocks are staggered around the four-down punch block;

[0013] Furthermore, the stopper forming adjustment device comprises an adjusting rod, and the position of the stopper is adjusted by the adjusting rod.

[0014] Furthermore, the block forming and adjusting device comprises a bevel ring mechanism, and the position of the block is adjusted by adjusting the relative positions of the upper and lower bevel rings.

[0015] Furthermore, the block forming and adjusting device also includes a threaded connection method.

[0016] Preferably, the block forming adjustment device can be a block forming adjustment plate or a block forming adjustment ring. It can be determined whether to use a block forming adjustment plate, a block forming adjustment ring, or a combination of the two according to different product requirements.

[0017] In addition, the present invention also provides a powder forming machine, other technical solutions of which are similar to those of the existing powder forming machine, and its block design includes the above-mentioned block layout system.

[0018] In summary, the present invention provides a stopper layout system for a powder forming machine. Through the offset layout between the stopper adjustment device and the stopper, a compact layout of the stopper and the stopper adjustment device of the lower five-punch mechanism is achieved on the premise of only increasing a small cost. By applying the offset layout scheme, the volume of the powder forming machine is reduced, the production cost of the powder forming machine is lowered, the operation of the machine is simpler, and the maintenance is more convenient.
