Description

Technical Field

[0001] The utility model relates to a tool for vacuum carburizing, in particular to a tool for placing parts during carburizing. Background Art

[0002] Carburizing is currently one of the most effective methods for strengthening the surface of steel parts and is the most widely used chemical heat treatment method in production. Vacuum pulse carburizing is increasingly used due to its high precision and excellent surface quality. However, compared to other carburizing methods, vacuum carburizing places higher demands on the placement of the carburized parts. To achieve a more uniform carburized layer, vacuum carburizing requires that the contact between the carburized part and the material frame be point or line contact, avoiding surface contact as much as possible. This fundamentally differs from other heat treatment loading methods. Utility Model Content

[0003] The new purpose of the utility model is to provide a tool for vacuum carburizing, which can effectively reduce the contact area between the parts and the material frame and ensure that the parts are placed stably during the carburizing process.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a tool for vacuum carburizing, the tool comprising a material frame and a workpiece support; there are multiple workpiece supports, which are respectively installed on the material frame, and the parts to be carburized are placed in the workpiece support; the workpiece support comprises a railing and a support column; there are multiple railings, which are arranged on the periphery of the workpiece support to limit the displacement of the parts; the support column is arranged in the center of the workpiece support to support the parts; the length directions of the railings and support rods are both vertically upward, and the length of the railings is greater than the length of the support rods.

[0005] Preferably, the tooling further comprises an annular ring, which is arranged around the inner periphery or the outer periphery of the railing.

[0006] Preferably, the bottom of the handrail is connected to the bottom of the support rod by a connecting rod.

[0007] Preferably, there are four railings, which are arranged opposite to each other in pairs, and the bottoms of the oppositely arranged railings are connected by a connecting rod.

[0008] Preferably, the bottom of the support rod is fixed to the intersection of the connecting rods.

[0009] Preferably, the workpiece supports are evenly arranged in the transverse and longitudinal directions of the material frame.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The material frame allows the parts to be in a "suspended" state, with each surface of the parts contacting the frame as little as possible, while ensuring that the parts can be placed stably in the material frame and will not fall easily;

[0012] 2. This tooling is simple to make and easy to use, effectively reducing the contact between parts and tooling;

[0013] 3. The tooling has no restrictions on the shape of the parts that need to be carburized, and can effectively meet the use requirements for parts of any shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is combined with Figure 1-2 The utility model is further described in detail: a vacuum carburizing tool, including a material frame and a workpiece support; the workpiece support is installed on the material frame 4, and the parts that need to be carburized are placed in the workpiece support. Figure 1 As shown, the workpiece support consists of four long rails 1 on the periphery, a short support column 2 in the middle, and an annular ring 3. During carburizing, the part is placed within the area enclosed by the annular ring 3. The rails 1 and annular ring 3 prevent the part from shifting left or right, while the support rods 2 prevent the part from falling. The interaction between the rails 1, annular ring 3, and support rods 2 keeps the part contained within the workpiece support. Only a portion of the part contacts the workpiece support, effectively achieving point or line contact.

[0019] As a preferred implementation of this embodiment, four railings 1 are arranged opposite to each other in pairs, and the bottoms of the oppositely arranged railings are connected by connecting rods; at the same time, the bottoms of the support rods 2 are fixed at the intersection of the connecting rods.

[0020] As a preferred implementation of this embodiment, Figure 2 As shown, a plurality of workpiece holders are placed in a material frame, and the workpiece holders are evenly arranged in the transverse and longitudinal directions of the material frame 4 .

[0021] The utility model is applied to the vacuum carburizing of parts to reduce the contact between the parts and the material frame, effectively reduces the contact between the parts and the material frame, greatly reduces the contact area between the parts and the material frame, and well meets the relevant requirements of actual production.

[0022] The above merely describes the inventive design principles and performance advantages of the vacuum carburizing tooling and is not limited to the above embodiments. The above embodiments and descriptions merely illustrate preferred embodiments of the present invention. Any modification or equivalent replacement of the present invention's technical solution without departing from the scope of the present invention's technical solution shall be covered by the scope of protection of the present invention.
