Polygonal riveting die

Abstract

The utility model discloses a polygonal riveting die which comprises an L-shaped supporting base, a mounting table is vertically arranged on one side of the L-shaped supporting base, a rotating ring is installed on the mounting table in a sleeved mode, the rotating ring rotates outside the mounting table, the mounting table is provided with a plurality of jacking columns, and the jacking columns are all distributed on the side face of the mounting table in an inclined surrounding mode. The multiple jacking columns move obliquely on the side face of the mounting table, and the other ends of the multiple jacking columns make contact with the rotating ring. When a polygonal workpiece needing to be riveted and pressed is transversely placed between the mounting tables, the rotating ring deflects outside the mounting tables, the rotating ring can eject and move the multiple ejection columns to the centers of the interiors of the mounting tables, at the moment, the other ends of the multiple ejection columns punch the workpiece at the same time, and therefore the exterior of the workpiece can be riveted and pressed into the polygonal workpiece.

Description

Technical Field

[0001] This utility model relates to the field of riveting dies, and in particular to polygonal riveting dies. Background Technology

[0002] The crimping of cold-pressed terminals for connectors on the market is mainly done using manual crimping pliers and blade crimping. Manual crimping of thicker wires is time-consuming and laborious, and it is easy to damage the crimping tools, resulting in low work efficiency. Blade crimping is difficult for technicians to adjust the machine, and the crimped terminals have large burrs, uneven appearance, and unstable quality. Blade crimping cannot meet the special requirements of customers for crimping height and width (non-standard crimping), which affects product quality. Therefore, a polygonal crimping mold is proposed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A polygonal riveting die includes an L-shaped support base. A mounting platform is vertically arranged on one side of the L-shaped support base, and a rotating ring is fitted onto the mounting platform. The rotating ring rotates outside the mounting platform. The mounting platform is provided with several top posts, which are obliquely distributed around the side of the mounting platform. The top posts can move obliquely on the side of the mounting platform, and the other end of the top posts contacts the rotating ring.

[0005] Preferably, the rotating ring is provided with a plurality of sliding grooves, and the plurality of sliding grooves are obliquely formed around the side wall inside the rotating ring, and one end of the plurality of top posts is vertically slidably inserted into the plurality of sliding grooves.

[0006] Preferably, a connecting frame is vertically arranged on the other side of the L-shaped support, and a cylinder is vertically installed at the bottom of the connecting frame, and the cylinder is driven by the rotating ring.

[0007] Preferably, a drive rod is provided between the cylinder and the rotating ring, with one end of the drive rod being driven to the cylinder and the other end being connected to the rotating ring.

[0008] Compared with the prior art, the beneficial effects of this utility model are: when the workpiece to be riveted into a polygon is placed horizontally between the mounting platforms, the rotating ring will deflect outside the mounting platform and push several top posts to the center inside the mounting platform. At this time, the other ends of several top posts will simultaneously press the workpiece, so that the workpiece can be riveted into a polygonal workpiece.

[0009] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 In this embodiment of the utility model, the polygonal riveting mold includes an L-shaped support base 1. A mounting platform 7 is vertically arranged on one side of the L-shaped support base 1, and a rotating ring 5 is fitted on the mounting platform 7. The rotating ring 5 rotates outside the mounting platform 7. The mounting platform 7 is provided with a plurality of top posts 6, which are obliquely distributed around the side of the mounting platform 7. The top posts 6 move obliquely on the side of the mounting platform 7, and the other end of the top posts 6 contacts the rotating ring 5. When the polygonal workpiece to be riveted is placed horizontally between the mounting platforms 7, the rotating ring 5 deflects outside the mounting platform 7 and pushes the top posts 6 to the center inside the mounting platform 7. At this time, the other end of the top posts 6 simultaneously punches the workpiece, so that the workpiece can be riveted into a polygonal workpiece.

[0017] The rotating ring 5 is provided with a number of sliding grooves 9, and the sliding grooves 9 are all obliquely formed around the inner side wall of the rotating ring 5. One end of each of the several top posts 6 is vertically slidably inserted into the sliding grooves 9. Thus, when the rotating ring 5 deflects on the side of the mounting platform 7, it can drive the sliding grooves 9 to shift, thereby pushing the several top posts 6 and converging them towards the middle of the mounting platform 7.

[0018] A connecting frame 2 is vertically arranged on the other side of the L-shaped support 1, and a cylinder 3 is vertically installed at the bottom of the connecting frame 2. The cylinder 3 is connected to the rotating ring 5 for driving, thereby driving the rotating ring 5 to deflect outside the mounting platform 7 through the cylinder 3.

[0019] A drive rod 4 is provided between the cylinder 3 and the rotating ring 5. One end of the drive rod 4 is connected to the cylinder 3, and the other end of the drive rod 4 is connected to the rotating ring 5, so that when the cylinder 3 drives the drive rod 4 to move, it drives the rotating ring 5 to deflect.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
