Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of machining, specifically relates to a stamping die for processing butterfly pin. BACKGROUND
[0002] Figure 1 It is a structural diagram of butterfly pin, and the butterfly pin is bent from a steel wire, and is widely used in various mechanical products, for example, the anti-skid chain of agricultural machinery disclosed in Chinese utility model patent publication No. 2018209316658 and the diesel engine oil quantity control switch disclosed in Chinese utility model patent publication No. 2021206116986 both use the butterfly pin. SUMMARY
[0003] The utility model solves the technical problem of providing a stamping die for processing butterfly pin.
[0004] To solve the above technical problem, the technical scheme of the utility model is as follows: a stamping die for processing butterfly pin, comprising an upper die, a lower die and a lower die seat, the lower die is fixedly installed on the lower die seat, a downward V-shaped deep groove is arranged in the middle part of the lower die, the upper die faces on the left and right sides of the V-shaped deep groove are provided with wave-shaped shallow grooves, the lower die face of the upper die is provided with wave-shaped shallow grooves matched with the lower die, and a plug plate matched with the V-shaped deep groove is arranged, and a cutter is arranged on the side face of the upper die.
[0005] The stamping die provided in the above technical scheme can stamp a steel wire into a butterfly pin workpiece as shown in Figure 2 , and subsequent simple processing of the workpiece can obtain a butterfly pin as shown in Figure 1 .
[0006] As a further technical scheme, a buffer is arranged at the bottom of the V-shaped deep groove, the buffer is a rectangular frame bent from a round steel bar and sleeved on the lower die. The round steel bar rotates when the plug plate of the upper die is downwardly stamped, so that a certain buffering effect is achieved, and the wear of the bottom surface of the V-shaped deep groove caused by long-time stamping is reduced, so that the service life of the lower die is prolonged.
[0007] Further, a feeding mechanism and a limiting mechanism are arranged on the lower die seat, the feeding mechanism is located on the same side as the cutter, and the limiting mechanism is located on the other side.
[0008] Further, a fine adjustment bolt is arranged on the limiting mechanism.
[0009] In an embodiment, the feeding mechanism is provided with a guide groove.
[0010] The stamping die has the advantages of ingenious design and simple structure, can quickly cut and stamp the steel wire, and greatly improves work efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0016] In order to make the utility model purposes, technical scheme and advantages more clear and obvious, the utility model is described in detail below combining with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not limited to the utility model.
[0017] In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and is not indicative or implied that the indicated device or element must have a particular orientation, a particular orientation and operation, therefore, it cannot be understood as a limitation on the utility model.
[0018] As Figures 1 to 4The stamping die shown includes an upper die 1, a lower die 2, a lower die base 3, a feeding mechanism 4, and a limiting mechanism 5. The lower die 2, the feeding mechanism 4, and the limiting mechanism 5 are all fixedly installed on the lower die base 3. The feeding mechanism 4 is spaced apart on the left side of the lower die 2, and the limiting mechanism 5 is located on the right side of the lower die 2. The feeding mechanism 4 is provided with a guide groove, and the limiting mechanism 5 is provided with a fine-adjusting bolt 6. The lower die 2 has a downward-facing V-shaped deep groove 2a in the middle, and the upper die surfaces on both sides of the V-shaped deep groove 2a are provided with wavy shallow grooves. The upper die 1 is installed on the stamping equipment through the die shank at its upper end. The lower die surface of the upper die 1 is provided with a wavy shallow groove that cooperates with the lower die 2, and a plate 1a that cooperates with the V-shaped deep groove 2a. A cutter 1b is installed on the right side of the upper die 1, and the cutter 1b corresponds to the gap between the feeding mechanism 4 and the lower die 2.
[0019] As a further technical solution, a buffer 7 is placed at the bottom of the V-shaped deep groove 2a. The buffer 7 is a rectangular frame made of bent round steel bars, which fits onto the lower die 2. This round steel bar will rotate when the upper die's insert plate 1a is pressed downwards, thus playing a certain buffering role, and can also reduce the wear on the bottom surface of the V-shaped deep groove 2a caused by long-term pressing.
[0020] Using the stamping die provided in this embodiment, a section of steel wire can be stamped into the shape shown below. Figure 2 The butterfly pin workpiece shown can be obtained by performing a simple bending process on the workpiece. Figure 1 The butterfly pin shown.
[0021] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the scope of this utility model patent.
[0022] To facilitate understanding by those skilled in the art of the improvements of this utility model over the prior art, some of the drawings and descriptions of this utility model have been simplified, and for clarity, some other elements have been omitted from this application. Those skilled in the art should realize that these omitted elements may also constitute the content of this utility model.
