A continuous heat treatment furnace for motorcycle hub

Abstract

The invention relates to a continuous motorcycle hub heat treatment furnace which comprises a furnace body (1), a heat treatment chamber (2), a heating body (3) and a furnace door (4), wherein the heating body (3) is positioned in the heat treatment chamber (2) and heat motorcycle hubs. The furnace further comprises a hanging rack movement system (5), wherein the hanging rack movement system (5) comprises a plurality of hanging rack devices (51), a pushing mechanism (52) and an opening (53) formed in the upper part of the furnace body (1); the hanging rack devices (51) with the motorcycle hubs (6) hung enter from a first transverse opening (530) of the furnace body (1); and the hanging rack devices (51) are driven to move forward along a longitudinal opening (532) by a driving device, and are successively lifted out of a second transverse opening (531) after heat treatment. In a treatment process, the motorcycle hubs (6) are arrayed side by side, and a stacking mode is avoided, so that the hubs do not easily deform due to stress; in addition, the hubs are heated more uniformly; and a space utilization ratio in the furnace is increased.

Description

technical field [0001] The invention relates to the field of electric furnaces, in particular to a continuous heat treatment furnace for motorcycle hubs. Background technique [0002] At present, the special heat treatment furnaces for motorcycle hubs are generally split-type treatment and continuous treatment. Such as figure 1 As shown, the split-back treatment is to put the hubs into the furnace in batches, heat treatment for a period of time until the treatment is completed, and then take out the hubs for a new round of heat treatment. This kind of processing mode has low processing efficiency, limited processing capacity, low utilization rate of space and temperature in the furnace, high work operation intensity, and is not suitable for large-scale continuous production. Continuous processing, the main way of conveying in the furnace is the furnace roller type, the furnace roller is placed at the bottom of the furnace, the heated hub is placed on the furnace roller, an...

Problems solved by technology

This kind of processing mode has low processing efficiency, limited processing capacity, low utilization rate of space and temperature in the furnace, high operating intensity, and is not suitable for large-scale continuous production.

Continuous processing, the main way of conveying in the furnace is the furnace roller type, the furnace roller is placed at the bottom of the furnace, the heated hub is placed on the furnace roller, and the furnace roller rotates slowly to push the hub forward. Usually, the hub is stacked in a material frame For heat treatment, due to the high stacking density of the hubs in the stacking method, the hubs are stacked on each other, and the hubs cannot be heated well, resulting in uneven heating of the hubs and affecting the heat treatment effect

In addition, the way of stacking may cause deformation of the hub under stress, which will affect subsequent processing
