Description

Technical Field

[0001] The utility model belongs to the technical field of spring manufacturing, and in particular relates to a single-loop buckle spring elbow auxiliary tool device. Background Art

[0002] The buckle spring elbow is an important process in buckle spring production. The original operation of the single-turn buckle spring elbow depends on the operator's experience and is free-bending on a vise. The size of the part elbow is difficult to guarantee, the precision is low, the production efficiency is low, and there are safety hazards. Therefore, it is necessary to design a single-turn buckle spring elbow auxiliary tool device to realize the production of single-turn buckle springs. The key points to be improved in the single-turn buckle spring elbow auxiliary tool device are: designing a bottom mold, a wrench, and a pin auxiliary tool device. For this purpose, a single-turn buckle spring elbow auxiliary tool device with a reasonable design is provided. Utility Model Content

[0005] (II) Technical solution

[0006] In order to solve the above technical problems, the utility model provides a single-turn buckle spring elbow auxiliary device, comprising: a bottom die 1, a wrench 2, a pin 3, and a buckle spring 4;

[0007] The bottom mold 1 is a rectangular bottom plate, a positioning portion is provided in the middle of the bottom mold 1, a threaded hole is provided at the side end of the bottom mold 1 perpendicular to the bottom plate surface, and a circular through hole is provided in the middle of the positioning portion;

[0008] The wrench 2 is arranged on the bottom die 1, and is provided with a bending portion and a handle. The bending portion is arranged in an arc shape, and a through hole is opened at the end of the bending portion. The through hole is placed on the threaded hole of the bottom die 1, and the pin 3 is inserted into the through hole and the threaded hole to lock the bottom die 1 and the wrench 2 in the horizontal direction;

[0009] The buckle spring 4 is placed on the bottom mold 1, one end of the buckle spring 4 is placed at the circular through hole of the positioning part, and the other end abuts against the handle.

[0010] The depth of the threaded hole at the side end of the bottom mold 1 is set to 20 mm;

[0011] The diameter of the circular through hole on the positioning portion is set to 3 mm, and the depth is set to 9.5 mm. The circular through hole on the positioning portion is used to penetrate the elbow end on one side of the buckle spring 4.

[0012] As described above, the diameter of the through hole on the curved portion of the wrench 2 is set to 5 mm.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model has the following beneficial effects: simple and convenient operation, improving production efficiency by 3 times, solving the problems of low efficiency and low safety in the original single-turn spring elbow process, and having reliable quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a schematic diagram of the structure of the device. DETAILED DESCRIPTION

[0016] In order to make the purpose, content, and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments.
