Description

Technical Field

[0001] The invention relates to the technical field related to automobile parts processing, in particular to a heat treatment quenching furnace for automobile parts processing. Background Art

[0002] During the processing of auto parts, in order to ensure the quality and hardness requirements of the parts, it is necessary to heat treat the metal parts, that is, to heat the auto parts at high temperature through a quenching furnace to make the metal structure inside the auto parts harder;

[0003] The quenching furnace will generate a lot of heat during the heating process. The full utilization of energy can reduce production costs during the production and processing process, while improving the efficiency of production and processing, so as to speed up the efficiency of heat treatment of automotive parts.

[0004] Current:

[0005] 1. In the existing common heat treatment quenching furnace for automobile parts processing, a large amount of heat will be lost in the quenching furnace when the user takes out the automobile parts during the heat treatment process, so that the temperature inside the quenching furnace needs to be reheated to the working temperature for subsequent use. The low energy utilization rate will increase the production cost;

[0006] 2. The existing ordinary heat treatment quenching furnace for automobile parts processing needs to place the parts on a fixed frame when processing automobile parts. However, the sizes of automobile parts are different, so the spatial structure of the fixed frame needs to adapt to the parts of different sizes to improve the applicability of the heat treatment equipment;

[0061] The user can first push the left fixing component 18 along the rectangular sliding groove of the supporting plate 7 to the left side of the sliding groove of the supporting plate 7, and at the same time, the elastic snap-fitting strips 20 on the front and rear sides of the middle part of the supporting plate 7 are snap-fitted to the middle part of the front and rear sides of the inner wall of the automobile accessory, and at the same time, the locking component 19 can be aligned with the left edge of the accessory and clamped and limited by rotating the rotating connecting shaft 1901, and then the right fixing component 18 is snap-fitted into the inside of the sliding groove of the supporting plate 7, and the right locking component 19 is limited to the edge of the right end of the accessory, and then the rotating knob 1804 can be rotated to drive the adjusting rod 1803 to rotate by rotating the knob 1804, and the serrated ring 1802 is driven to rotate by the sliding bar structure, so that the serrated block on the right side of the outer ring of the serrated ring 1802 drives the rack at the end of the snap-fitting round button 1801 to slide, so that the snap-fitting round button 1801 snaps into the inner wall of the sliding groove of the supporting plate 7;

[0062] When the left fixing component 18 slides through the conical sliding block 2104, it will squeeze the spring of the limiting sleeve rod 2103 close to the end of the conical sliding block 2104. At the same time, when the user needs to take out the accessories, he can turn the rotating knob 1804 to rotate the adjusting rod 1803, and drive the limiting sleeve rod 2103 to slide and adjust the horizontal position through the rack gear set 2105, so that the auxiliary component 21 can assist in pushing the fixing component 18 out of the sliding groove of the support plate 7 under the elastic force of the left elastic sleeve rod 2101. At the same time, the spring compression degree at the end of the arc-shaped locking strip 2102 is reduced, so that the friction force on the surface of the end of the arc-shaped locking strip 2102 close to the auxiliary component 21 can be reduced;

[0063] When closing the sliding sealing door 3, the sliding shaft block 13 inside the groove at the end of the sliding sealing door 3 can slide along the slide groove of the right-angle slide rail 4 and seal closed, and then the cooling fan 2 and the heat treatment equipment 5 are started to work.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
