A kind of watch hairspring coiling machine

Abstract

The invention discloses a coiling machine for balance springs of watches. The coiling machine comprises a driving motor, a driving control switch, an electromagnetic control assembly and a coiling machine head. The driving motor is suspended on a machine body platform, and the electromagnetic control assembly is fixed onto the bottom surface of a fixing plate; a belt pulley on a motor shaft of the driving motor drives a belt pulley of the coiling machine head; a linkage lever of the electromagnetic control assembly pushes a mold releasing base to move upwardly. The coiling machine has the advantages that a draw bar type locking positioning mode is adopted, accordingly, interference between locking force of a positioning conical surface of a clamp nozzle and locking force of a draw bar can be prevented, a coiling mandrel positioning reference can be guaranteed, and the coiling mandrel rotation precision can be improved; troublesome operation steps can be omitted owing to an electromagnetic mold releasing mode, accordingly, the labor intensity of operators can be reduced, and the production efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a wire coiling machine, in particular to a wire coiling machine for processing watch hairsprings for coiling and forming. Background technique [0002] The coiling of watch hairspring is an important process in the production of watch hairspring. The coiling machine used is the key equipment for hairspring forming. It largely determines the quality of coiled hairspring, especially the concentricity of the forming mandrel rotation. degree, directly affects the pass rate of the product, and the way of locking the mandrel is the key part that affects the concentricity of the forming mandrel rotation, and the operating structure of the coiling machine equipment also directly affects the production of the product Efficiency, etc., these will have a great impact on the quality of the hairspring and the production efficiency of the product. figure 1 is a schematic diagram of the locking and positioning of the coiled mandrel in the pr...

[0002] The coiling of watch hairspring is an important process in the production of watch hairspring. The coiling machine used is the key equipment for hairspring forming. It largely determines the quality of coiled hairspring, especially the concentricity of the forming mandrel rotation. degree, directly affects the pass rate of the product, and the way of locking the mandrel is the key part that affects the concentricity of the forming mandrel rotation, and the operating structure of the coiling machine equipment also directly affects the production of the product Efficiency, etc., these will have a great impact on the quality of the hairspring and the production efficiency of the product

figure 1 is a schematic diagram of the locking and positioning of the coiled mandrel in the prior art, such as figure 1 As shown, the locking position of the coiled mandrel is locked by the nut, and the elastic groove on the clamp must be locked by the inner tapered surface of the lock nut; Concentricity with the inner cone surface), resulting in uneven force on the cone surface of the clamping nozzle during locking, which directly affects the positioning reference when the clamping nozzle is elastically clamped, resulting in unsatisfactory rotation accuracy of the coil wire mandrel

in addition, figure 2 It is a schematic diagram of the structure of the manual demoulding of the wire coiling machine, such as figure 2 As shown in the figure, every time the hairspring is coiled, it is necessary to manually pull the demoulding handle at the lower part of the coiling machine to remove the material and demould. The operation process is cumbersome, time-consuming and laborious, and the production efficiency is low.
