Problems solved by technology
In the prior art, heat treatment is generally carried out by laying it flat on the bottom plate of the heat treatment furnace in a free state. During the heat treatment process, the plane of the part and the ribs on the facade are thermally deformed, the size and flatness requirements cannot be guaranteed, and the scrap rate is high.

The invention provides a strip part heat treatment shape control clamp and a clamping method. The strip part heat treatment shape control clamp is fixed and clamped by adding a clamp plate between a bottom plate and a pressing plate; and a pin shaft is arranged on the bottom plate, an upper wedge block is used for downward pressure, and a lateral wedge block is used for lateral force application,so that the shape of parts in the heat treatment processing process is ensured. According to the strip part heat treatment shape control clamp and the clamping method, the technical problems that theparts in the prior art that are directly placed on the bottom plate of a heat treatment furnace, the parts have large thermal deformation in the plane and the vertical ribs, the size and flatness requirements cannot be guaranteed, and the scrap rate is higher are solved.
Description
technical field [0001] The invention belongs to the technical field of heat treatment of lath parts, and in particular relates to a shape control fixture and a clamping method for heat treatment of lath parts. Background technique [0002] The slat part is composed of web and rib welding. There are protrusions at both ends of the web of the part. The thickness of the part is uneven. The overall length is 1.4 meters. The part requires vacuum heat treatment to eliminate the welding stress of the part, stabilize the size of each part, and ensure the plane of the part degree requirements. In the prior art, heat treatment is generally carried out by laying it flat on the bottom plate of the heat treatment furnace in a free state. During the heat treatment process, the plane of the part and the ribs on the facade are thermally deformed, the size and flatness requirements cannot be guaranteed, and the scrap rate is high. Contents of the invention [0003] In order to solve the a...
