Abstract
The utility model discloses an antenna shrapnel stamping part, which comprises a connecting frame (1) and two rows of sheet materials (2) which are distributed on the connecting frame at intervals from the width direction; and a connecting material belt (3) is arranged between the two rows of plates, and positioning holes (4) which correspond to each plate of the two rows of plates one by one are uniformly distributed on the connecting material belt along the length direction of the connecting frame. The utility model has the advantages that the middle material bridge is cancelled, the positioning holes are transferred to the middle part of the material belt, the hole distance between two rows of positioning holes is shortened, the middle strength of the material belt is good, and the feeding is stable; the step pitch is reduced, the product can be more compact, spm is superior to the old design, the consumption of metal raw materials is saved, and meanwhile, the reduction of the step pitch can reduce the electroplating cost.
Description
Technical Field
The utility model relates to an antenna shell fragment especially relates to antenna shell fragment stamping workpiece before the antenna shell fragment shaping.
Background
The mobile phone antenna elastic sheet is widely applied to the communication field at present, the die manufacturing technology has the advantages of being fast in forming, capable of achieving batch processing, capable of guaranteeing processing accuracy and the like, the production of the mobile phone antenna elastic sheet mostly uses a single stamping mode at present, the antenna elastic sheet is a continuous material belt before stamping, the antenna elastic sheet comprises a connecting frame and a product to be stamped, the product to be stamped is a sheet material, and the sheet material is separated from the connecting frame through stamping so that a part with a certain shape, size and performance can be obtained. The specific process of stamping comprises blanking, fine blanking, drawing, spinning, bending, flanging, bulging and the like. As shown in fig. 1, the existing material belt includes two rows of top and bottom plates, the top and bottom plates are in one-to-one correspondence and are connected into a whole through an intermediate material bridge, positioning holes are formed at two sides of a connecting frame, the material belt is fixed on a punching machine through the positioning holes, the hole distance between the two rows of positioning holes is large, due to the existence of the intermediate material bridge, a large gap exists between two adjacent plates of each row of plates, the punching step distance is large, more waste materials are generated during punching, and meanwhile, the cost of a subsequent electroplating process is high.
Like chinese utility model patent publication No. CN205150438U discloses an automatic packagine machine that cuts of antenna shell fragment, chinese utility model patent publication No. CN212599258U discloses the material area cuts the mechanism, and chinese utility model patent publication No. CN103406442B discloses a cell-phone antenna shell fragment mould, all is the improvement of making from the angle that improves material area machining efficiency, does not see at present and carries out the modified report to the material area structure.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that the die-cut meeting of current antenna shell fragment material area structure produces more metal waste, and die-cut cost is higher, also can rise follow-up electroplating process's cost simultaneously, provides the antenna shell fragment stamping workpiece of a new construction for this reason.
The technical scheme of the utility model is that: the antenna shrapnel stamping part comprises a connecting frame and two rows of plate materials which are distributed on the connecting frame at intervals from the width direction; and a connecting material belt is arranged between the two rows of plates, and positioning holes which correspond to each plate of the two rows of plates one by one are uniformly distributed on the connecting material belt along the length direction of the connecting frame.
In the scheme, the width of the connecting frame is 22.5mm, the thickness of the connecting frame is 0.08mm, and the punching step distance is 3 mm.
In the scheme, the two rows of plate materials comprise large ends and small ends, and the large ends of the two rows of plate materials are connected with the connecting material belt.
In the scheme, the connecting frame and the two rows of plates are made of stainless steel.
In the scheme, the two rows of plates are symmetrically distributed about the central axis of the connecting frame.
The utility model has the advantages that the middle material bridge is cancelled, the positioning holes are transferred to the middle part of the material belt, the hole distance between two rows of positioning holes is shortened, the middle strength of the material belt is good, and the feeding is stable; the step pitch is reduced, the product can be more compact, spm is superior to the old design, the consumption of metal raw materials is saved, and meanwhile, the reduction of the step pitch can reduce the electroplating cost.

Detailed Description
The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments of the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 2, the antenna dome stamping part includes a connecting frame 1 and two rows of plate materials 2 spaced apart from each other in the width direction on the connecting frame; and a connecting material belt 3 is arranged between the two rows of plates, and positioning holes 4 which correspond to each plate of the two rows of plates one by one are uniformly distributed on the connecting material belt along the length direction of the connecting frame.
Specifically, the width of the connecting frame is 22.5mm, the thickness of the connecting frame is 0.08mm, and the punching step distance is 3 mm. As shown in fig. 1, the conventional antenna spring stamping part has a corresponding size of 21mm in width, 0.08mm in thickness, and a punching pitch of 4 mm. The step size is seen to be reduced by 1 mm.
The plates of the two rows of plates comprise large ends 21 and small ends 22, and the large ends of the two rows of plates are connected with the connecting material belt. The punched product is shown in fig. 3, and the connecting frame and the two rows of plates can be made of stainless steel or other metal materials.
