A method of making a pipe clamp assembly pliers

1. The present invention relates to a pipe clamp assembly pliers, which belongs to the technical field of automobile air conditioning pipeline assembly tooling.

Background technique:

2. The pipe clamp for automobile air conditioning pipeline is a kind of fastener used to fix the air conditioning pipeline in the automobile When the road is arranged inside the car, several pipe clamps are required to fasten it, so as to prevent the pipeline from shaking and wear during the driving process, and ensure the stability of the pipeline installation during driving.

3. In the mass production stage of automobiles, the assembly of pipe clamps is completed by special pipe clamp assembly tooling. However, in the prototype stage of new projects in the early stage, the lack of pipe clamp assembly tooling often causes the on-site assemblers to use "vise". "To complete the assembly, when using the "vise" to assemble, it is necessary to first put the rubber sleeve on the designated position of the pipeline, then put the pipe clamp on the rubber sleeve, and then manually place the upper pipe clip 1501 and the lower pipe clamp of the pipe clamp. The pieces 1502 are pressed together, and the lugs 1503 on the pipe clamp 15 are bent down with a "vise" while maintaining the press, so that the pipe clamp is closed. The disadvantages are: (1) As shown in Figure 1, due to When the lug 1503 is bent downward with a vise, the pipe clamp 15 will move in the direction away from the jaws of the vise under the pressing action of the vise on the lug 1503. To other auxiliary tools, other personnel even need to assist to fix the pipe clamp 15, and another person uses a "vise" to bend the lugs on the pipe clamp downward to complete the closing of the pipe clamp, which wastes a lot of labor time; (2) This operation method cannot guarantee the flatness of the folded lugs 1503, the clamping quality, and the clamping consistency; (3) In addition, when the lugs 1503 of the pipe clamp are not clamped in place at one time During the installation, the staff will repeatedly squeeze the pipe clamp 15, causing the anti-corrosion layer on the surface of the pipe clamp 15 to fall off, resulting in the problem that the pipe clamp is easy to corrode; (4) This assembly method is time-consuming, labor-intensive, inefficient, and the operator is easily fatigued. Risk of vise pinch etc.
