[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] See also Figure 1-Figure 8 , this application provides the following technical solutions:

[0045] A servo motor stamping part continuous die includes an upper die 10 and a lower die 20. A conveying system for conveying a material belt is arranged between the upper die 10 and the lower die 20. Several workstations are arranged between the upper die 10 and the lower die 20. According to the overall type of the workstation, the continuous die includes a punching station 1, a knife edge station, a buckle point station 3, a product station and a cutting station 8. The punching station 1 can open a circular hole on the workpiece; there are several knife edge stations, which can cut the workpiece into different required shapes; the buckle point station 3 can process the buckle points at the circular hole; there are two product stations for placing products for stacking, and the two product stations correspond to the production of products of different specifications; the cutting station 8 is located at the end of the production process and is used to cut waste.

[0046] The overall shape of the products that can be produced by the continuous mold of this scheme is as follows Figure 1 As shown, product A and product B can be processed at the same time, and the outer and inner diameters of the two products are different, such as Figure 2 As shown in the figure, the changes of the material strip at each workstation are shown, wherein the positions shown at the first product workstation 5 and the second product workstation 7 are the cutting states of product A and product B, that is, Figure 2 The corresponding annular structure area in the first product station 5 and the second product station 7. In this way, the production efficiency of the servo motor stamping parts can be greatly improved.

[0047] Based on the above implementation scheme, see Figure 2 and Figure 5 In order to process two different products, the punching station 1 includes six sets of punching knife groups. Each punching knife group includes two punching knife heads, which can punch round holes on the workpiece at the same time. With the center of the product as the center, the punching knife heads of the same punching knife group are arranged in a straight line corresponding to the radius of the product. The punching knife heads of the punching knife group are arranged in a radial distribution corresponding to the product. The effect of the punching is as follows Figure 1 The corresponding position of the punching station 1 in the figure is shown. The cutter head is made of tungsten steel. Since the parts are large, the punch is divided to reduce the cost of the punch parts.

[0048] On the basis of the above implementation scheme, the cutting station includes the first cutting station 2, which is a counting cutting station. The action frequency of the first cutting station 2 corresponds to the setting of the punching station 1. For every 50 actions of the punching station 1, the first cutting station 2 performs a punching action once. In other words, this product is grouped into 50, and the first cutting station 2 performs an action only when the punching station 1 is in the 50th operation state.

[0049] With the forward direction of the workpiece when being processed on this mold as the front, the buckle point station 3 is arranged in front of the first cutting edge station; the buckle point station 3 and the corresponding processing position of the first cutting edge station 2 shear and bend the workpiece.

[0050] A finished product is 50 pieces of product A or product B stacked together, 49 of which have punched shapes and only 1 piece is processed with dot points, so the first cutting station 2 and the dot point station 3 must use counting to punch holes every 50 punches and repeat the cycle.

[0051] Based on the above implementation scheme, see Figure 7 and Figure 8 The number of punches in the buckling point station 3 corresponds to the number of drilling tool heads in the drilling station 1; the end of the punch in the buckling point station 3 facing the lower die is an inclined surface, and the bending processing of the buckling point structure is formed through the inclined surface.

[0052] Because the buckle point is relatively small, this solution uses the punch of the buckle point station 3 to complete the shearing and bending actions at the same time during processing, which does not affect the workpiece accuracy and can improve the processing efficiency. The buckle point station 3 only has a gap of 0.01mm on one side of the shearing position, and the buckle point generated by puncture is used to stack the products.

[0053] On the basis of the above implementation scheme, the cutting station also includes a second cutting station 4, which is arranged on the front side of the buckle station 3; the second cutting station 4 can cut out a circular hollow structure in the middle of the product; the product corresponding to the first product station 5 is product A, and the second cutting station 4 cuts the internal hollow circular part of product A.

[0054] The first product station 5 is arranged at the front side of the second blade 4, and can stack the product A and cut the outer edge of the product A. At the first product station 5, the processing of the product A can be completed.

[0055] The cutting station also includes a third cutting station 6, which is arranged in front of the first product station 5 and can cut the inner edge of the product B. The inner hollow circular part of the product B can be cut out by the third cutting station 6.

[0056] The product station also includes a second product station 7, which is arranged in front of the third cutting station 6, and can stack product B and cut the outer edge of product B; the cutting station 8 is arranged in front of the second product station 7.

[0057] The corresponding product A or product B is placed at the first product station 5 and the second product station 7 respectively, and the knife edge is used to combine with bending to form it in one step, and then the bending shape is used to hook the previous product. When the products are stacked to the required quantity, the gap between the parts on the mold and the products is used to strengthen the compactness of the product stacking. The tightening ring is used to generate reverse force when stacking the products at the two product stations, so that the products are compact after stacking. The tightening ring is only 0.01mm smaller than the single side of the product appearance.

[0058] On the basis of the above implementation scheme, the upper die 10 includes an upper die base 11, an upper die pad 12, an upper clamping plate 13, a stripping pad 14 and a stripping plate 15 arranged in sequence from top to bottom; the lower die 20 includes a lower die base 21, a lower die pad 22 and a lower die plate 23 arranged in sequence from bottom to top. The specific connection structure of the upper die 10 and the lower die 20 can be implemented by using existing technology. It only needs to meet the following three points:

[0059] 1. Use a 110T punching machine with a punching speed of 80 times / min.

[0060] 2. The dimensional tolerance of bending and cutting edge parts is ±0.005mm.

[0061] 3. Polishing of the bending and forming parts.

[0062] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
