Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped spring production, in particular to a production mold for numerically controlled machining of special-shaped springs. Background Technique

[0002] A spring is a mechanical part made of metal materials with elasticity. Under the action of an external force, it will deform within a certain range. At the same time, springs can be divided into helical springs, scroll springs, leaf springs, special-shaped springs, etc. In the production process of special-shaped springs, production molds for special-shaped springs are often used.

[0003] During the long-term use of the existing special-shaped spring production molds, since the forming positioning pins will continuously contact the raw materials, and the diameters of the special-shaped springs are inconsistent, the forces received by the positioning pins on the molds will continuously change. And the positioning pins are directly fixedly connected to the telescopic plate through bolts. The fixing method by bolts will cause the forming pins to shift during long-term use, affecting the accuracy of the processing and forming of special-shaped springs.

[0004] In the patent document with the publication number of CN216540679U, a production mold for special-shaped springs for numerical control machining is proposed. The device includes a mold body. An ejector is provided on the side of the mold body. An internal grinding pin is fixedly connected to the side of the mold body relative to the position of the ejector. Two forming components are symmetrically provided on the side of the mold body. The forming component includes an electric telescopic rod fixedly connected to the side of the mold body. A connecting plate is fixedly connected to the side end of the electric telescopic rod. An installation groove is opened at the side end of the connecting plate. A forming block is clamped in the installation groove through a plurality of convex pads. A threaded rod is threadedly connected to the top of the connecting plate, ensuring that the forming block will not shift or shake during use, affecting the accuracy of the processing and forming of special-shaped springs.

[0005] However, during the production process of the device for springs, waste chips are likely to accumulate, thus easily affecting the production efficiency of the springs.

[0006] Therefore, we urgently need to provide a production mold for numerically controlled machining of special-shaped springs. Content of the Utility Model
