Problems solved by technology

Although the utility model solves the problem of providing a continuous mold for continuous processing of crimping frames, the structure of the mold is complex, and the formed crimping frames are all consistent, so it is impossible to realize one-time differentiated production
[0004] The Chinese Utility Model Patent No. 201020291119.6 discloses a continuous mold, which includes an upper mold plate and a lower base plate for fixing the mold. The lower part of the upper template is fixed with a number of punches, the die and the punch are facing up and down, and the two sides of the die are respectively provided with guide plates, and the guide plates are used to transfer the blank. Incision and cutter, this utility model and its equivalent deformation still cannot realize the continuous production of a group of asymmetrical hinge blades

Embodiment 1

[0035] Example 1, such as figure 1 As shown, the present invention discloses a method for continuously producing a group of asymmetric hinge blades. The method uses a continuous mold to process long strips at the same time. The specific steps are as follows: The surface of the continuously conveyed long strip is punched with round holes. In this embodiment, 7 round holes are punched each time; Specific process such as figure 1 As shown; then the strip after the trimmed burr is initially positioned to determine the step distance, and then the square hole is cut. In this embodiment, two symmetrical square holes are cut on the strip; then use two Different fillet forming punches perform fillet forming on both sides of the strip after cutting the square hole. The specific process is as follows: figure 1 As shown; then use the bending forming punch to bend the two sides of the rounded strip at 90°, the specific process is as follows figure 1 shown; and then use the rolling formi...

Embodiment 2

[0037] Example 2, such as figure 1 with figure 2 As shown, the present invention discloses a mold for continuously producing a group of asymmetric hinge blades, including an upper mold 1 and a lower mold 2, and the upper mold 1 includes an upper mold base 11, an upper backing plate 12 and an upper template 13 , the lower mold 2 includes a lower mold base 21 and a lower template 22, the upper mold 1 and the lower mold 2 are connected by an inner guide post 3, and a mold cavity is formed between the upper and lower molds, and the strip material 4 enters through the feeding rack 5 In the mold cavity, on the upper mold 1, a round hole punch 61, a symmetrical edge trimming punch 62, a symmetrical square hole cutting punch 63, and asymmetric rounded corner forming punches 64, Bending and forming punches 65 symmetrical on both sides, round forming blocks 66 symmetrical on both sides, and cutting punches 67 arranged in the center.

[0038] On the upper die 1, a symmetrical position...

Abstract

The invention discloses a method for continuous production of one group of asymmetric hinge blades. The method comprises the steps of feeding, punching circular holes, removing rough edges by cutting, cutting square holes, forming round angles, performing 90-degree bending, performing circle rolling and forming, and cutting. The invention further discloses a continuous die for production by applying the method, which comprises an upper die and a lower die, wherein the upper die and the lower die are connected through an inner guide pole, a strip material is sent to a die cavity through a feeding frame, and various punches are sequentially mounted on the upper die. Through the design of the technical scheme, the working efficiency of the product can be greatly improved, the original processing technology needs a plurality of workers to perform single-working position processing sequentially, and the processing technology only needs one person to operate after improvement, thereby greatly reducing the production cost.

Description

technical field [0001] The invention relates to a production method and equipment produced by the method, in particular to a method for continuously producing a group of asymmetric hinge blades and a mold for producing hinge blades using the method, belonging to the field of mechanical processing. Background technique [0002] In the prior art, multiple single-station molds are used to process the hinge blades sequentially, and the multiple molds are independent of each other. In particular, the asymmetrical hinge blades can only be lowered after one processing link is completed. For the processing of one link, if one worker is needed for one link, then multiple workers need to cooperate with each other to complete the processing of the entire hinge blade, which is not only inefficient, but also a waste of labor. [0003] The Chinese utility model patent No. 201020235917.7 discloses a continuous die, which includes a patrix and a lower die, and the patrix includes a patrix, ...
