Description

Technical Field

[0001] The utility model belongs to the technical field of tooling, and specifically relates to a forming tooling for copper alloy tubular rivets. Background Art

[0002] Copper alloy tubular rivets are mainly used in the riveting occasions of non-metallic materials without load. Because of the neat appearance of this type of rivet and its ability to firmly fix materials, this product uses copper alloy tubes and is formed by flanging the head. Since copper alloy is relatively soft, problems such as pinching, deformation, and the increase in the size of the rod part under the head caused by flanging are likely to occur during the flanging process. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above-mentioned drawbacks and provide a forming tooling for copper alloy tubular rivets that will not cause pinching and deformation of the rod part, and the size of the rod part under the head will not increase.

[0004] The purpose of the utility model and the solution to its main technical problems are achieved by adopting the following technical solutions:

[0005] A forming tooling for copper alloy tubular rivets of the utility model includes a tailstock, a protective sleeve, and a forming body. Its characteristics are that a protective sleeve is installed inside the tailstock, and the forming body is inserted into the protective sleeve.

[0006] There are two protective sleeves. One end of one is a flat surface, and one end of the other is provided with a convex head.

[0007] There are two forming bodies. One end of one is conical, and one end of the other is provided with a groove.

[0008] Compared with the prior art, the utility model has obvious beneficial effects. From the above technical solutions, it can be seen that by installing a protective sleeve inside the tailstock and inserting the forming body into the protective sleeve. The prepared part blank is inserted into the protective sleeve with a flat surface at one end of the flaring fixture, and then the protective sleeve with a flat surface at one end and the part blank are together inserted into the hole of the tailstock. The protective sleeve with a flat surface at one end and the part blank are closely attached to the bottom of the hole of the tailstock. Install the flaring cone head forming body with a conical surface at one end on the lathe tailstock, and use the movement of the lathe tailstock to extrude the inner hole of the part blank through the conical surface of the flaring cone head forming body with a conical surface at one end to achieve flaring. After the flaring is completed, replace the forming die, insert the flared part into the protective sleeve with a convex head at one end of the forming die, then install it on the tailstock, and after installing the forming body with a groove at the other end, through the extrusion of the protective sleeve with a convex head at the other end and the forming body with a groove at the other end, the head of the part is formed by flanging. During the flanging process, the lathe does not rotate. Due to the protection of the protective sleeve, pinching and deformation of the rod part will not occur, and the size of the rod part under the head will not increase, achieving no pinching and deformation of the rod part and no increase in the size of the rod part under the head.

[0017] The following is a detailed description of the specific embodiments, structures, features and functions of the present utility model in conjunction with the accompanying drawings and preferred embodiments.

[0018] A copper alloy tubular rivet forming tooling of the present utility model includes a tailstock 1, a protective sleeve 2, and a molded body 3. It is characterized in that a protective sleeve 2 is installed inside the tailstock 1, the molded body 3 is inserted into the protective sleeve 2, there are two protective sleeves 2, one end of one is a flat surface, and the other end is provided with a convex head, and there are two molded bodies 3, one end of one is conical, and the other end is provided with a groove.

[0019] In use: First, calculate the cutting length according to the specifications and dimensions of part 4 and perform cutting. Clamp the tailstock 1 of the flaring fixture on the spindle of an ordinary lathe. Then, insert the blank of part 4 into a protective sleeve 2 with a flat end of the flaring fixture. Next, install the protective sleeve 2 with a flat end and the blank of part 4 together into the hole of the tailstock 1. The protective sleeve 2 with a flat end and the blank of part 4 are in close contact with the bottom of the hole of the tailstock 1. Install a flaring cone head forming body 3 with a conical end on the lathe tailstock. Use the movement of the lathe tailstock to extrude the inner hole of the blank of part 4 through the conical surface of the flaring cone head forming body 3 with a conical end to achieve flaring. After flaring is completed, replace the forming die. Install the flared part 4 into a protective sleeve 2 with a convex head at the other end of the forming die, and then install it on the tailstock 1. After installing another forming body 3 with a groove at the other end, through the extrusion of the protective sleeve 2 with a convex head at the other end and the forming body 3 with a groove at the other end, the head of part 4 is formed by flanging.

[0020] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
