Description

Technical Field

[0001] The utility model belongs to the field of heat treatment material frame hangers, and specifically relates to a material frame rapid separation hanger for a bottom loading production line. Background Art

[0002] Bottom-loading production lines have been widely used due to their high degree of automation, ability to achieve continuous production, and programmable control of the entire production process. In the actual production process of bottom-loading production lines, it is often encountered that quenching can be done in the same furnace, but tempering cannot be done in the same furnace. For quenching in the same furnace and tempering in different furnaces, how to remove the quenched parts into different tempering furnaces is a difficult problem. Conventionally, the parts are manually removed from the material frame during the interval between quenching and tempering, and placed in another material frame for tempering. This has the following problems: ① Bottom-loading production lines produce many parts, and manual removal is slow and inefficient; ② Operators need to climb onto mobile material carts to operate, which poses a safety hazard; ③ Manual separation is prone to omission or misplacement, resulting in unqualified parts or even missing parts.

[0003] Therefore, providing a rapid separation hanger for the material frame of a bottom loading production line is an urgent problem to be solved by the present invention. Utility Model Content

[0004] In view of the above-mentioned existing technology, the purpose of the present invention is to overcome the shortcomings of the existing technology and adapt to actual needs, thereby providing a bottom loading production line material frame rapid separation hanger that can solve the problems of slow part separation and easy omission caused by quenching in the same furnace but tempering in different furnaces in the existing bottom loading production line, and improve the separation efficiency of parts with different tempering requirements after quenching in the bottom loading furnace.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A lifting device for rapid separation of material frames in a bottom loading production line comprises a lifting ring, a cross fixing frame, a vertical pole and a supporting arm. The bottom of the lifting ring is fixed to the upper end of the cross fixing frame. Four vertical poles are provided. The upper ends of the four vertical poles are respectively connected to the four ends of the cross fixing frame. The bottom of the four vertical poles is respectively connected to a supporting arm, and the supporting arm can rotate freely relative to the vertical pole.

[0007] Furthermore, a first through hole for connecting to the crane is provided at the center of the lifting ring, and the bottom of the lifting ring is welded to the middle of the upper end of the cross fixing frame.

[0008] Furthermore, the cross fixing frame is made by welding four square steels, the angle between adjacent square steels is 90 degrees, and the four square steels are the same length.

[0009] Furthermore, the upper ends of the four uprights are respectively welded to the four ends of the cross fixing frame.

[0010] Furthermore, the support arm is a rectangular thick plate with a second through hole at one end. One end of the support arm is welded to the bottom of the vertical pole after passing through the second through hole with a screw, and the support arm can rotate freely 360° relative to the screw, and the other end of the support arm is in contact with the material frame.

[0011] Furthermore, the inner diameter formed by connecting the vertical rod and the cross fixing frame is larger than the outer diameter of the heat treatment tooling, which can ensure that the lifting device can freely lift out the uppermost material frame.

[0012] Furthermore, it also includes a reinforcement ring, which is sleeved on the outer sides of the four vertical poles and fixed on the outer ends of the four vertical poles.

[0013] Furthermore, the reinforcing ring is annular and is provided in plurality. The plurality of reinforcing rings are evenly welded to the four vertical poles, and the inner diameter of the reinforcing ring is the same as the outer diameter of the vertical pole and the cross fixing frame assembly.

[0014] In the present invention, the number and position of the reinforcement rings can be selected according to the height and load-bearing capacity of the sling of the present invention.

[0015] The method of using the utility model is as follows: the utility model sling is lifted above the heat treatment tooling by using a crane, and then the height of the utility model sling is lowered to be lower than the height of the first layer of material frame, the direction of the supporting arm is manually turned toward the center of the material frame, and the crane is started to lift out the first layer of material frame. If it is necessary to continue to lift out the material frame, the above steps are repeated.

[0016] The beneficial effects of this utility model are as follows: for bottom-loading production lines where quenching can be performed in the same furnace but tempering cannot, the use of this sling allows for the rapid separation of parts with different tempering requirements, improving product quality while significantly increasing production efficiency. It also virtually eliminates the risk of missing or misplacing parts. Manual separation of parts requires the operator to climb onto the material cart, which presents a safety hazard. The use of this sling virtually eliminates such hazards. BRIEF DESCRIPTION OF THE DRAWINGS
