[0010] 1. The top cover of this utility model is provided with several round holes for hanging the workpiece in the frame, which can realize vertical quenching and heating of the workpiece; after heating, it can also be vertically cooled together with the tooling, greatly reducing the deformation of the workpiece.

[0011] 2. The top and bottom surfaces of the frame of the utility model can be fixedly connected by several longitudinal rods, that is, the side surface of the frame is composed of only several longitudinal rods, so that the hollow area of the side surface is maximized and the quenching efficiency is improved.

[0012] 3.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] The utility model provides a vacuum furnace vertical quenching tool, such as Figure 1 、 2 As shown, the tooling includes a top cover 1 and a frame 3. The frame 3 has no top or bottom, and the side of the frame 3 is provided with a hollow structure. The top cover 1 is detachably mounted on the top of the frame 3. The top cover 1 is provided with several circular holes for hoisting the workpiece 2. One end of the workpiece 2 passes through the circular hole and is located inside the frame 3, while the other end of the workpiece 2 engages with the circular hole and is located outside the top cover 1. In this embodiment, one end of the workpiece 2 passes through the circular hole from the outside of the top cover 1 and is located inside the frame 3. The other end of the workpiece 2 is provided with a circular boss. The boss diameter is larger than the circular hole diameter. The circular boss engages with the circular hole and is located outside the top cover 1. In another embodiment, the workpiece 2 has a frustum structure. The small diameter end of the workpiece 2 passes through the circular hole and is located inside the frame 3, while the large diameter end of the workpiece 2 engages with the circular hole and is located outside the top cover 1. The workpiece 2, top cover 1, and frame 3 can be easily and quickly installed in a vacuum furnace to achieve vertical heating of the workpiece 2. After heating, the workpiece 2 can be quenched into a cooling medium together to achieve vertical cooling of the workpiece.

[0018] In actual use, if the workpiece 2 is not convenient to fit into the round hole, a through hole can be punched on the excess of the workpiece 2. The through hole is fixedly connected to the round hole by a wire. The wire can be passed through the through hole and the round hole to tie the workpiece 2 to the top cover 1 so that it can be vertically hoisted in the frame 3.

[0019] Preferably, the top and bottom surfaces of the frame 3 are fixedly connected together by several longitudinal rods, that is, the frame 3 is a column structure composed of the top, bottom and longitudinal rods. The bottom and top surfaces of the frame 3 can be rectangular, and the column structure is a cuboid; the bottom and top surfaces of the frame 3 can also be circular, and the column structure is a cylinder; several longitudinal rods fix the top and bottom surfaces of the frame 3 to maximize the hollow structure area of the side of the frame 3, while ensuring the stability of the frame and improving the quenching and cooling efficiency.

[0020] In order to adapt to workpieces of different sizes, multiple top covers 1 can be manufactured, and the diameter of the circular hole on each top cover 1 is different.

[0021] The top of the frame 3 may be provided with a groove, and the bottom surface of the top cover 1 may be provided with a protrusion corresponding to the groove. The protrusion cooperates with the groove to limit the top cover 1 to the top of the frame 3.

[0022] A lifting ring may also be installed on the frame 3 for use in lifting it in a common box-type quenching furnace.

[0023] The utility model can realize vertical heating and cooling of workpieces, has the advantages of convenient and quick installation and disassembly, simple structure, low manufacturing price and easy use.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
