Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a metal parts heat treatment device. Background Art

[0002] Heat treatment is a metal processing technology that heats, keeps warm, and cools metal materials in a certain medium to control their performance by changing the metallographic structure on the surface or inside of the material. The heat treatment process includes three processes: heating, keeping warm, and cooling.

[0003] One of the important steps in spring processing and production is to heat treat the springs, and a heat treatment rack will be used to fix the springs. When in use, the springs are mostly fixed in place by hoisting or serial stacking. However, in actual use, precision springs need to be fixed individually. Each spring requires an independent fixing method to prevent the springs from contacting and affecting each other, and the springs from deforming when heated and changing their accuracy. It is also not possible to fix springs of different models at the same time without affecting each other. Utility Model Content

[0004] The purpose of the utility model is to solve the following problems existing in the prior art:

[0005] One of the important steps in spring processing and production is to heat treat the springs, and a heat treatment rack will be used to fix the springs. When in use, the springs are mostly fixed in place by hoisting or serial stacking. However, in actual use, precision springs need to be fixed individually. Each spring requires an independent fixing method to prevent the springs from contacting and affecting each other, and the springs from deforming when heated and changing their accuracy. It is also not possible to fix springs of different models at the same time without affecting each other.

[0006] In order to solve the problems existing in the prior art, the utility model provides a metal parts heat treatment equipment, including a base plate, a support rod is arranged on the top of the base plate, a top plate is arranged on the top of the support rod, a clamping block is arranged on the top of the base plate, a center rod is arranged on the top of the clamping block through a connecting plate, a limiting groove is opened on the surface of the center rod, and a pressure block is clamped in the limiting groove.

[0007] The utility model provides a metal parts heat treatment equipment.

[0008] Furthermore, a support rod is provided at the bottom of the base plate, and lifting ears are provided on both sides.

[0009] Furthermore, the bottom plate surface is rectangular and has a plurality of support rods arranged in rows, and a top plate is arranged on the top of each support rod.

[0010] Furthermore, the support rod is fixedly connected to the top plate and has a T-shaped cross section. A gap is left between each top plate and the support rod, and the gap distance is adapted to the block.

[0011] Furthermore, the clamping block is divided into a bottom block and a top rod, wherein the bottom block is located on a side close to the support rod, and the top rod is located on a side close to the top plate.

[0012] Furthermore, the diameter of the center rod is adapted to the inner diameter of the spring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model forms a cross-shaped grid on the top of the bottom plate through supporting rods and a top plate. When in use, a card block with a center rod of different specifications is selected according to the spring model, and the spring is sleeved on the outside of the center rod on the top of the card block. The operator can insert the card block into the inside of the grid along the edge of the grid. The supporting rods and the top plate on both sides of the card block restrict the card block so that it can only move and will not tip over, and the operator can adjust the position of the card block at will. At this time, the spring sleeved on the outside of the center rod at the top of the top plate is restricted by the center rod to maintain an upright state, and then the pressure block is placed along the limiting groove, and the bottom of the pressure block contacts the spring to further restrict the spring in the vertical direction, thereby reducing the shaking of the spring. After the placement is completed, the overall structure is hoisted into the heat treatment furnace through the lifting ear, and another bottom plate can be stacked on the top of the center rod to improve work efficiency.
