Vacuum heat treatment equipment

Abstract

The invention discloses vacuum heat treatment equipment. The vacuum heat treatment equipment comprises a machine body platform, a furnace body, a constant-temperature control system, a vacuum containing chamber, a vacuum pipeline, a transmission system, a circulating water cooling system and a vacuum unit, wherein the machine body platform forms a hollow cavity for containing the vacuum containing chamber, and the furnace body is arranged on the machine body platform in a sliding manner; the vacuum pipeline is arranged on the machine body platform through a fixed base, and the output end of the vacuum unit is connected with an exhaust port of the vacuum pipeline; and the vacuum containing chamber is connected with the vacuum pipeline through a flange. The vacuum heat treatment equipment provided by the invention has the beneficial effects that the vacuum containing chamber is connected with the vacuum pipeline through a flange disc, the folding type opening and closing of the vacuum containing chamber and the vacuum pipeline are realized through a reduction box connected with a shocking wheel and a steering gear, and the operation is safe and convenient; in addition, an operation handle rotates, the multi-point locking is realized, the locking force is uniform and reliable, the vacuum degree is stable, and the reliability is high; a dual-layer water box supplies circulating water in a step-by-step manner, the automatic circulating cooling on the vacuum unit is finished, the continuous cooling effect is good, the floor space is reduced, and a water resource is saved.

Description

technical field [0001] The invention relates to a vacuum heat treatment equipment, in particular to a vacuum heat treatment equipment for setting and tempering watch hairsprings, springs and precision parts. Background technique [0002] Hairspring and spring are two very important elastic components in watches, and vacuum setting heat treatment is an important process in the production of watch hairspring and spring. Determines the quality of hairsprings and springs; at present, large-scale vacuum heat treatment equipment is used, which is suitable for processing hairsprings and springs with a single variety and fixed batches; it is not suitable for processing with frequent variety changes. In addition, the existing vacuum chamber and vacuum pipeline The sealing connection part of the seal, the locking device adopts the folding method of the eccentric shaft rod, and there are multiple points of locking force distributed on the sealing connection flange, and they need to be ...

[0002] Hairspring and spring are two very important elastic components in watches, and vacuum setting heat treatment is an important process in the production of watch hairspring and spring. Determines the quality of hairsprings and springs; at present, large-scale vacuum heat treatment equipment is used, which is suitable for processing hairsprings and springs with a single variety and fixed batches; it is not suitable for processing with frequent variety changes. In addition, the existing vacuum chamber and vacuum pipeline The sealing connection part of the seal, the locking device adopts the folding method of the eccentric shaft rod, and there are multiple points of locking force distributed on the sealing connection flange, and they need to be locked separately. The locking force is easy to cause unevenness, poor reliability, and directly affects The stability of the vacuum degree of the equipment; the vacuum chamber and the vacuum pipeline are connected separately, and the operator needs to move the vacuum chamber to and from the loading and unloading during use, resulting in time-consuming and labor-intensive manual operations and safety issues

To sum up, the existing vacuum heat treatment equipment is no longer suitable for the current market requirements for changing watch varieties.
