Description

Technical Field

[0001] This utility model belongs to the field of heat treatment technology, specifically relating to a fixing device for reducing the deformation of a spade plate during heat treatment. Background Technology

[0002] The spade plate is an important component of an artillery system, primarily used to support the gun and transfer recoil force during firing. Spade plates have a large bottom area and are generally made of wide plates. This product has strict dimensional requirements. The common production method for heat treatment involves placing the spade plate on channel steel for heat treatment. However, the small furnace load of parts results in significant deformation of the plates during heat treatment, making correction extremely difficult and even causing parts to be scrapped, thus affecting production schedules. The increased frequency of heat treatment also leads to substantial energy consumption.

[0003] Therefore, it is necessary to provide a suitable heat treatment fixing device to reduce the deformation problem of the spade plate during heat treatment. Utility Model Content

[0004] The purpose of this invention is to provide a fixing device that reduces the deformation of the spade plate during heat treatment, so as to overcome the shortcomings of existing spade plate heat treatment and improve heat treatment efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A fixing device for reducing the deformation of a spade plate during heat treatment includes a frame, a support frame fixedly installed inside the frame, the support frame and the frame being integrally formed, and a plurality of hollow grooves provided inside the support frame.

[0007] Furthermore, hanging columns are provided on all four sides of the frame.

[0008] Furthermore, both the frame and the support frame are made of cast steel.

[0009] Furthermore, the frame and support frame have the same thickness.

[0010] Furthermore, the horizontal width of the frame is more than twice the horizontal width of the bottom of the spade plate.

[0011] Furthermore, the longitudinal length of the frame is greater than the longitudinal length of the bottom of the spade plate.

[0012] The beneficial effects of this utility model are as follows: the fixing device can accommodate two anchor plates. Each heat treatment furnace can produce 6 parts, increasing the furnace loading capacity, improving production efficiency, and saving energy and reducing consumption. Using this device, the heat treatment deformation of the anchor plates is basically controlled, and it can be used in conjunction with other parts for furnace production, meeting the needs of parts production.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings to provide a better understanding of this utility model.

[0019] like Figures 1 to 4 The fixing device shown, designed to reduce deformation of the spade plate during heat treatment, includes a frame 1. A support frame 3 is fixedly installed inside the frame 1, forming an integral part of the frame 1. Multiple hollow grooves 4 are provided inside the support frame 3, which facilitate heat transfer during heat treatment. Hanging columns 2 are provided on the top and bottom sides of the frame 1 for easy chain hoisting of moving objects. Both the frame 1 and the support frame 3 are made of cast steel. The frame 1 and the support frame 3 have the same thickness. The lateral width of the frame 1 is more than twice the lateral width of the spade plate's bottom. The longitudinal length of the frame 1 is greater than the longitudinal length of the spade plate's bottom.

[0020] In use, before heat treatment of the spade plate, the spade plate is manually positioned on one side of the fixing device and then spot-welded to the support frame 3 at its bottom. The bottom perimeter of the spade plate is also spot-welded to the frame 1. This process is repeated to spot-weld another spade plate to the other side of the fixing device. This device can accommodate two spade plates. Each heat treatment furnace can produce six parts, increasing the furnace loading capacity, improving production efficiency, and saving energy.

[0021] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
