Problems solved by technology

However, due to the frequent impact of high temperature and quenching water on the feed tray, the stress cannot be effectively released, which will lead to problems such as cracking and damage of the feed tray, which requires frequent replacement of the feed tray and increases production costs.

Embodiment Construction

[0024] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on the specific embodiments and in conjunction with the accompanying drawings.

[0025] This embodiment provides a tray for heat treatment of special-shaped blades, including an outer frame 1 and several rib plates 2 arranged in the outer frame 1, see figure 1 , the tray is rectangular, the length of the tray is 4000mm, and the width of the tray is 2000mm. Several ribs 2 in the outer frame 1 are arranged along the length direction of the tray, and the distance between adjacent ribs 2 and the distance between the outer frame 1 and adjacent ribs 2 are equal. Between the adjacent ribs 2 and between the outer frame 1 and the adjacent ribs 2, bolts 3 are alternately installed, and the bolts 3 are arranged perpendicular to the length direction of the ribs 2, see figure 1 .

[0026] Among them, the outer frame 1 of the tray and ...

Abstract

The invention discloses a material tray used for thermal treatment of special-shaped cutter plates, and relates to the technical field of thermal treatment jigs. The material tray comprises an outer frame and a plurality of rib plates arranged in the outer frame; all the rib plates are arranged in a mode of being parallel to the length direction of the material tray; every two adjacent rib platesas well as the outer frame and the adjacent rib plates are connected through bolts; besides, the bolts are vertical to the direction of the length direction of the rib plates; and the outer frame andthe rib plates are all manufactured by adopting Ni-family steel plates. The material tray has the advantages that the main body is made by adopting the Ni-family steel plates which are high in strength and low in ductility, so that the material tray can only deform after scouring of rainwater without cracking; and scrapping of the material tray caused by cracking is avoided, so that the service life of the material tray is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of heat treatment tooling, in particular to a material tray for heat treatment of special-shaped blades. Background technique [0002] Heat treatment equipment is equipment for annealing, tempering, quenching, heating and other heat treatment operations on workpieces. In order to reduce the hardness of metal workpieces, improve their cutting performance, eliminate residual stress, and reduce deformation and cracks, it is necessary to anneal the workpiece. [0003] When heat-treating heterosexual blades, because the blades have the characteristics of large size difference, different shapes, and small single weight, especially small-sized blades, they cannot be directly put into the heating furnace, and the workpiece can only be placed in the material. On the tray, the whole panel production mode is simulated through the tray. However, due to the frequent impact of high temperature and quenching water on the ...
