Problems solved by technology

[0003] The existing heat treatment tooling is a special tooling for processing a single part, with a single scope of application. If you want to heat treat multiple types of parts, you can only process multiple tooling, which wastes time, manpower and materials, and greatly increases the processing cost; and in the past The heat treatment tooling is usually made of heat-resistant steel or heat-strength steel with high heat resistance in order to reduce deformation, the cost is very high but the effect is still unsatisfactory; and when the maximum charging capacity is pursued, the increase in load will aggravate the tooling. The degree of deformation, and the dense distribution of products will affect the atmosphere; therefore, the existing heat treatment tooling often cannot comprehensively have the characteristics of large furnace loading, small deformation of the tooling itself, uniform atmosphere, low cost and long life

Embodiment

[0025] Such as figure 1 and figure 2 As shown, the heat treatment tooling of this embodiment is installed inside the furnace, including a frame 1 and a guide tube 2, the guide tube 2 is sleeved on the periphery of the frame 1, and the frame 1 includes a support shaft 11 and several trays 12. A plurality of trays 12 are perpendicular to the axis of the support shaft 11 and are fixed on the support shaft 11. When heat treating the parts, the parts to be processed can be placed on each tray 12. The multiple trays 12 arranged axially along the support shaft 11 can maximize the use of the vertical space in the heat treatment furnace, which not only increases the maximum furnace charge during a single treatment, speeds up the work efficiency, but also makes the waiting time The distribution of the processing parts is more dispersed, so that the heating degree of the parts is more uniform, and the load bearing of each layer of trays 12 is also reduced, prolonging the service life o...

Abstract

The invention discloses a heat treatment tool. The tool is arranged in a hearth and comprises a frame tool and a flow guide cylinder; the flow guide cylinder is arranged on the periphery of the frametool in a sleeving manner and comprises a supporting shaft and multiple trays, the trays are perpendicular to the axis of the supporting shaft and are fixed to the supporting shaft in a penetrating manner, and the heat treatment tool has the advantages of being wide in application range, large in charge batch, uniform in atmosphere, long in service life and the like.

Description

technical field [0001] The invention relates to the field of heat treatment, in particular to a heat treatment tool. Background technique [0002] Metal heat treatment is one of the important processes in mechanical manufacturing, and it is widely used. Heat treatment imparts or improves the required mechanical properties, physical properties and chemical properties of the workpiece by changing the microstructure inside the workpiece, or changing the chemical composition of the workpiece surface, so as to obtain different performance. For most mechanical parts, heat treatment process is often essential. For heat treatment technology, the design and use of heat treatment tooling is critical. [0003] The existing heat treatment tooling is a special tooling for processing a single part, with a single scope of application. If you want to heat treat multiple types of parts, you can only process multiple tooling, which wastes time, manpower and materials, and greatly increases ...
