The technical scheme of the utility model as follows:

the pin torsion spring molding manufacturing clamp comprises a main body, a chuck, a mandrel, a wrench, a pressing plate and a fastening bolt;

the main body is provided with a hiding groove and a fixing pin so as to facilitate the manufacturing and processing of the spring. The main part is provided with a mandrel hole, a mandrel is arranged on the mandrel hole, and a wrench is used for winding and forming the spring steel wire around the mandrel.

The main part on design have the chuck, the main part side-mounting tightly decides the bolt, through tightly screwing and loosening of tightly deciding the bolt for the chuck opens and shuts, so that the spring steel wire of clamp.

The wrench is sleeved on the mandrel, so that the steel wire is clamped by the bulge below the wrench, and the wrench is rotated to enable the steel wire to surround the core; the pressing plate is fixed on one side of the main body, the spring supporting legs are placed in the empty grooves of the main body, the central spiral part is placed in the positioning pins, and the pressing plate is used for pressing the spring steel wire.

The utility model has the advantages that:

the above structure is adopted in the utility model, utilize clamp plate pressure spring steel wire, utilize dabber and spanner to mutually support to use simultaneously, solved prior art and had spring size and appearance and can not obtain guarantee, drop into huge, the higher technical problem of manufacturing cost earlier. The utility model discloses an anchor clamps are small, simple structure, and spare part is few, easily processes, utilizes different positions to process manufacturing on a anchor clamps body. The utility model is suitable for single-person operation and can be processed and manufactured by a plurality of persons. The clamp can be operated by clamping the clamp on a bench vice, the tool has low manufacturing cost, safe and reliable use, high production efficiency and low labor intensity of a processor, the processed product has beautiful appearance, and the sizes of all parts meet the design requirement.

Detailed Description

The following describes the implementation of the present invention in detail with reference to the technical solutions and the accompanying drawings.

Example 1:

the pin torsion spring forming manufacturing clamp comprises a main body 1, a chuck 2, a mandrel 3, a wrench 4, a pressing plate 5 and a fastening bolt 6, wherein the main body 2 is provided with a clamping head;

the main body 1 is provided with a hiding groove and a fixing pin so as to facilitate the manufacturing and processing of the spring. The main part 1 is provided with a mandrel hole, a mandrel 3 is arranged on the mandrel hole, and a wrench 4 is used for winding and forming the spring steel wire around the mandrel.

The main body 1 on design have chuck 2, main body 1 side-mounting holding bolt 6 for through the tight and loosening of holding bolt 6, chuck 2 opens and shuts, so that the spring steel wire of clamp.

The wrench 4 is sleeved on the mandrel 3, so that the steel wire is clamped by the bulge below the wrench 4, and the wrench 4 is rotated to enable the steel wire to surround the core; the pressing plate 5 is fixed on one side of the main body 1, the spring supporting legs are placed in the empty grooves of the main body 1, the central spiral part is placed in the positioning pins, and the spring steel wire is pressed by the pressing plate 5.

Example 2:

the working method of the pin torsion spring molding manufacturing clamp comprises the following steps:

the first step is as follows: as shown in fig. 3, the spring wire required for the pin torsion spring is placed on the body 1, passed through the collet 2, and the set bolt 6 is tightened so that the wire is stationary. The mandrel 3 is placed into the pin hole, the wrench 4 is sleeved on the mandrel 3, the steel wire is clamped by the aid of the protrusion below the wrench 4, the wrench 4 is rotated to wind the steel wire around the mandrel 3, and transition fillets and spiral parts of the head of the pin torsion spring are manufactured.
