A mattress spring stress relief annealing equipment

Abstract

The invention relates to the technical field of spring processing, and discloses a mattress spring stress-relief annealing device, which includes a chassis, the four corners of the lower surface of the chassis are respectively connected to the tops of four groups of roller frames in rotation, and the bottoms of the roller frames rotate Rollers are connected, a motor frame is fixedly connected to the left bottom of the chassis, and the rear side of the motor frame is fixedly connected to the front side of the drive motor. The mattress spring stress relief annealing equipment, through the cooperating setting of the locking block, the locking groove and the inserting block, the chassis and the machine cover can be fixed to each other, and the coordinating setting of the high temperature resistant sealing strip and the sealing groove can make the chassis and the machine cover It achieves the effect of sealing and effectively prevents the heat in the chassis from overflowing. The locking block and the fixing plate achieve the effect of self-locking through the cooperation of the insert block and the second chute, and the heat preservation effect in the chassis is achieved through the setting of the insulation layer. , through the setting of the heating layer, the temperature in the chassis can be raised.

Description

technical field [0001] The invention relates to the technical field of spring processing, in particular to a mattress spring stress relief annealing equipment. Background technique [0002] The metal after cold deformation is heated below the recrystallization temperature to remove the internal stress, but still retains the heat treatment of cold hardening effect, which is called stress relief annealing, also known as low temperature annealing. The coil spring rolled by cold rolling process is generally Use lead bath isothermal quenching cold-drawn steel wire (carbon spring steel wire, piano steel wire) and oil quenching and tempering spring steel wire. The cover of the stress relief annealing equipment is not well sealed, and most of the cover and the chassis of the stress relief annealing equipment are not fixed firmly, which will easily cause the heat in the equipment to overflow, and in severe cases, it will cause a fire. Contents of the invention [0003] (1) Solved ...
