Abstract
Description
Technical Field
[0001] This invention relates to the field of powder forming machines, and more particularly to an integrated stop system for powder forming machines. Background Technology
[0002] Because powder forming machines can produce high-precision, smooth parts in one pass, and have the characteristics of wide applicability, high production efficiency and high material utilization, they have been favored by enterprises and are now widely used in the pressing of powder products of various metals, ceramics, bakelite and other materials. Moreover, the shapes of pressed products are becoming more and more complex, including multi-step parts, parts with through holes in the middle, and parts with blind holes with internal steps in the middle.
[0003] The function of the stop blocks in a powder forming machine is to define the forming positions of each punch. Different punches have different forming positions, and a single punch also has different forming positions during the forming process. The positioning accuracy of each forming position has a crucial impact on product precision, yield, and production efficiency. Furthermore, the punches have a certain weight, and the stop blocks must provide adequate strength to support them. Simultaneously, to ensure positioning accuracy, the support of the stop blocks for the punches must be centrally symmetrical. Considering cost and operating conditions, the dimensions of the punches, while meeting mechanical performance requirements, should be as small as possible to allow for the placement of more stop blocks within a limited space, enabling the pressing of products with more complex shapes.
[0004] Existing powder forming machines generally use square blocks. Figure 1 and Figure 2 An existing square stop block is shown. As shown, two stop blocks 1 are mounted on two stop block seats 2, and the two stop block seats 2 are mounted on a base plate 3. Although square stop blocks are simple to manufacture and low in cost, they are relatively large in size. Due to space limitations at the same height, usually only one set of stop blocks can be installed. How to install more stop blocks in a limited space has always been a technical problem that has troubled those skilled in the art.
[0005] Therefore, those skilled in the art are dedicated to developing an integrated stop system for a powder forming machine to enable the installation of more stops within a limited space. Summary of the Invention
[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that square blocks occupy a lot of space and it is impossible to set multiple sets of blocks at the same height.
[0007] To achieve the above objectives, the present invention provides an integrated stop system for a powder forming machine, including a stop platform and a stop, wherein the stop is mounted on the stop platform;
[0008] Furthermore,
[0009] Two blocks form a group, and each group of blocks is symmetrically arranged on the block platform;
[0010] Furthermore,
[0011] Each set of blocks has a similar shape and can be integrated in a close-fitting manner to reduce the overall size.
[0012] Furthermore, the integrated stop system of the powder forming machine of the present invention also includes a stop adjustment device, which is used to adjust the position of the punch plate defined by the stop. In existing stop systems, the stop adjustment device is disposed on the stop platform, and the height of the stop is adjusted by the stop adjustment device; in the integrated stop system of the powder forming machine of the present invention, the stop adjustment device is disposed inside the punch plate; the stop adjustment device includes an adjustment ring, the height of which is adjustable, and the position of the corresponding punch plate defined by the stop can be adjusted by adjusting the height of the adjustment ring.
[0013] In a preferred embodiment of the present invention, the integrated block is composed of multiple blocks with arc-shaped columns, and each group of blocks has the same degree of curvature, so that each group of blocks can be tightly attached to form a whole.
[0014] Furthermore, the bottom of each set of blocks is installed on the block platform;
[0015] Furthermore, the stop platform is installed on the base plate;
[0016] Furthermore, the two blocks in each group are arranged in a centrally symmetrical manner;
[0017] Furthermore, the dimensions of each set of blocks increase sequentially from the center outwards to make more efficient use of space; the space is small near the center, so the block size is reduced to fit the space; the space is large further away from the center, so the block size is increased to enhance the block strength.
[0018] Furthermore, the integrated stop block also includes an adjustment device for each group of stop blocks, including an adjustment mechanism and an adjustment ring; the stop block adjustment device is set in each punch plate of the powder forming machine corresponding to each group of stop blocks, and the adjustment ring is set to contact the corresponding stop block; the position of the adjustment ring is adjusted by adjusting the adjustment mechanism, thereby adjusting the position of the punch plate of the powder forming machine corresponding to each group of stop blocks.
[0019] Therefore, the present invention realizes an integrated stop block system for a powder forming machine. By changing the shape of the stop block and the setting position of the stop block adjustment device, the technical problem of the large space occupied by the existing square stop block system is solved, the volume of the stop block is reduced, and more stop blocks can be set in the same space than the existing square stop blocks, which can reduce the volume of the powder forming machine and reduce the cost.

The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.
[0029] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and the present invention does not limit the dimensions and thicknesses of each component.

[0030] Example 1
[0031] Figure 3-4 An integrated stop system suitable for a three-punch powder forming machine is shown in the figure:
[0032] The integrated stop system consists of three sets of stop blocks in the shape of arc-shaped cylinders. Each set of stop blocks has the same degree of curvature, so that the stop blocks can be tightly fitted into a whole.
[0033] like Figure 6 From a top-down view, the integrated stop block consists of three sets of stop blocks arranged in concentric circles: a pair of one-way downward-moving stop blocks (3), a pair of two-way downward-moving stop blocks (6), and a pair of three-way downward-moving stop blocks (9); among them,
[0034] The one-to-one downward blocking block 3 is located on the outermost side of the concentric circle and has the largest width; the three-downward blocking block 9 is located on the innermost side of the concentric circle and has the smallest width; the two-downward blocking block 6 is located in the middle of the concentric circle and has a width greater than the three-downward blocking block 9 but less than the one-downward blocking block 3.
[0035] A pair of one-way downward thrust blocks 3, a pair of two-way downward thrust blocks 6, and a pair of three-way downward thrust blocks 9 are respectively installed on a pair of block mounting plates 10 by bolt connection. The pair of block mounting plates 10 are installed on the base plate 11 by bolt connection.
[0036] Each stop block has a shape similar to an arc-shaped tile, and a pair of stops blocks have the same height. Their tops contact the punch plate.
[0037] The one-to-one punching block 3 is the tallest, and its top end is in contact with the block adjustment device set in the punching plate 1;
[0038] A pair of two downward punching blocks 6, with a height of 6, have their tops in contact with the block adjustment device located inside the two downward punching plates 4;
[0039] A pair of three-pronged downward-pointing blocks 9, with the lowest height, have their tops in contact with the block adjustment device located inside the three-pronged downward-pointing plate 7;
[0040] The stop adjustment device installed in each punch plate includes an adjusting worm, a transmission gear, and an adjusting ring, wherein the adjusting worm is connected to the transmission gear, and the transmission gear is connected to the adjusting ring; Figure 5 Taking a single-stroke as an example: the single-stroke stop adjustment device includes a single-stroke adjustment worm gear 12, a single-stroke transmission gear 13, and a single-stroke adjustment ring 2.
[0041] in,
[0042] The top of the one-to-one punch block 3 contacts the punch adjustment ring 2 set inside the punch plate 1;
[0043] The top of the pair of double-down punch blocks 6 contacts the double-down punch adjustment ring 5 located inside the double-down punch plate 4;
[0044] The top of a pair of three-stroke stop blocks 9 contacts the three-stroke adjustment ring 8 located inside the three-stroke plate 7;
[0045] By adjusting the worm gear 12, the worm gear 13 is driven to rotate. The worm gear 13 drives the worm gear 2, causing the position of the worm gear 2 within the worm gear 3 to change. Ultimately, this changes the relative position of the worm gear block 3 and the worm gear 1.
[0046] By adjusting the worm gear of the second punch, the transmission gear of the second punch rotates, and the gear of the second punch drives the adjustment ring 5 of the second punch, so that the position of the adjustment ring 5 of the second punch changes within the second punch plate 4, and finally the relative position of the second punch stop block 6 and the second punch plate 4 changes.
[0047] By adjusting the worm gear of the three-down punch, the transmission gear of the three-down punch rotates, and the gear of the three-down punch drives the adjusting ring 8 of the three-down punch, so that the position of the adjusting ring 8 of the three-down punch changes within the three-down punch plate 7, and finally the relative position of the three-down punch stop block 9 and the three-down punch plate 7 changes.
[0048] This invention realizes a three-pronged integrated stop block system for a powder forming machine. By changing the shape of the stop blocks and the setting position of the stop block adjustment device, the technical problem of large space occupation of the existing square stop block system is solved, the volume of the stop blocks is reduced, and more stop blocks can be set in the same space than the existing square stop blocks, which can reduce the size of the powder forming machine and reduce costs.
[0049] Example 2
[0050] Everything else is the same as in Example 1, with the addition of an appendix. Figure 5 and attached Figure 6 .
[0051] like Figure 5 and Figure 6 As shown, the adjusting ring of the stop adjustment device consists of an upper inclined ring 14 and a lower inclined ring 15. The upper inclined ring 14 and the lower inclined ring 15 are fixed as a whole inside the punch plate. The top surface of the upper inclined ring 14 is connected to the punch plate, the bottom surface of the upper inclined ring 14 is connected to the lower inclined ring 15, the top surface of the lower inclined ring 15 is connected to the upper inclined ring 14, and the bottom surface of the lower inclined ring 15 is in contact with the top of the stop. The upper inclined ring 14 and the lower inclined ring 15 can be offset in position under the drive of the transmission gear. The contact surfaces of the upper inclined ring 14 and the lower inclined ring 15 each include an inclined surface. When the relative position of the upper inclined ring 14 and the lower inclined ring 15 is offset, the thickness of the adjusting ring as a whole will change.
[0052] By adjusting the worm gear, the transmission gear is driven to rotate. The transmission gear drives the upper slant ring 14 and the lower slant ring 15 to shift their positions. The position of the bottom surface of the lower slant ring 15 that contacts the stop block changes within the punch plate, ultimately changing the relative position of the stop block and the punch plate.
[0053] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
