Description

Technical Field

[0001] This utility model relates to the field of steel ring processing technology, and more specifically, to a heat treatment device for processing steel ring forgings. Background Technology

[0002] Steel rims, also known as wheel hubs, are an important component of automobiles. In the manufacturing process of steel rims, one essential step is the heat treatment process. By heat treating the steel rims, the internal stress of the steel material can be removed, and the rigidity, hardness, wear resistance and fatigue strength of the parts can be greatly improved. Therefore, the heat treatment process of steel rims is particularly important.

[0003] To improve efficiency, existing steel ring heat treatment processes typically involve placing multiple steel rings simultaneously into the heat treatment apparatus. This allows for simultaneous heat treatment of multiple steel rings, increasing work efficiency. However, this method has some problems. Since the steel rings are placed on the workpiece, some supporting surfaces cannot be directly heated during the heat treatment process, resulting in uneven heating of the steel rings and affecting the quality of subsequent processing. Therefore, it is necessary to solve the problem of uneven heating when multiple steel rings are heated simultaneously. In view of this, we propose a heat treatment apparatus for processing steel ring forgings. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a heat treatment device for processing steel ring forgings, so as to solve the technical problem that the steel ring is placed on the workpiece position, which causes some supporting surfaces to be unable to be directly heated during the heat treatment process, resulting in uneven heating of the steel ring and affecting the subsequent processing quality.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heat treatment device for processing steel ring forgings, including a heating box and a transport vehicle, wherein a sealed heating chamber is formed by combining the heating box and the transport vehicle, and a plurality of rotatable support members are arrayed on the side wall corresponding to the rear plate of the transport vehicle and the heating box, and a plurality of steel rings are sleeved on the outer side of the support members, a drive mechanism that is inserted into the side end of the support members is installed on the side wall of the rear plate of the heating box, and a support roller that fits against the bottom of the steel ring is fixed on the top of the transport vehicle;

[0006] The transport vehicle includes a base plate that is connected to the bottom of the heating box, and a baffle that is connected to the front opening of the heating box is fixed on the outer side of the base plate.

[0007] The support includes a fixed plate fixed to the side wall of the baffle. A rotating column penetrating the baffle is rotatably arranged on one side of the fixed plate. A circular plate is fixed at the other end of the rotating column. Several support rods that fit against the side of the steel ring are fixed on the other side of the circular plate.

[0008] This invention combines a heating box with a transport vehicle to form a sealed heating space. The design of the support components on the side wall of the transport vehicle can fix the placement of multiple steel rings at once. With the cooperation of multiple circular plates and support rollers, the position of the steel rings can be kept stable. Then, by combining the support components with the drive mechanism, the drive mechanism can control the rotation of the support components. In this way, the steel rings can be kept in a rotating state during the heating process, which can improve the uniformity of heating and reduce the probability of uneven heating. This can improve the processing quality in subsequent work and reduce the impact of uneven stress on the processing quality.

[0009] Preferably, the support rod has a plurality of limiting protrusions elastically arranged on its wall to fit against the two sides of the steel ring, and the two opposing sides of the limiting protrusions are configured as V-shaped surfaces.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model combines a heating box with a transport vehicle to form a sealed heating space. The design of the support components on the side wall of the transport vehicle can fix the placement of multiple steel rings at once. With the cooperation of multiple circular plates and support rollers, the position of the steel rings can be kept stable. Then, by combining the support components with the drive mechanism, the drive mechanism can control the rotation of the support components. In this way, the steel rings can be kept in a rotating heating state during the heating process, thereby improving the uniformity of heating and reducing the probability of uneven heating. This can improve the processing quality in subsequent work and reduce the impact of uneven stress on the processing quality.

[0017] 2. This utility model further limits the position of the steel ring by elastically setting a limiting protrusion structure on the outer wall of the support rod.

[0024] like Figures 1 to 5As shown, this utility model relates to a heat treatment device for processing steel ring forgings, comprising a heating chamber 1 and a transport vehicle 2, wherein the heating chamber 1 and the transport vehicle 2 are combined to form a sealed heating chamber. Several rotatable support members 3 are arrayed and installed on the side walls corresponding to the rear plate of the transport vehicle 2 and the heating chamber 1. Several steel rings are fitted onto the outer side of the support members 3. A drive mechanism 4 is installed on the side wall of the rear plate of the heating chamber 1, which is inserted into the side end of the support member 3. A support roller 5, which fits against the bottom of the steel ring, is fixedly installed on the top of the transport vehicle 2. The combination of the heating chamber 1 and the transport vehicle 2 can form a closed system. The heating space, the top of the heating box 1 is equipped with a heating mechanism, which is existing technology and is not specifically shown here. It is used to heat the steel ring. The rotatable support 3 can drive the steel ring to rotate under the control of the drive mechanism 4. This can keep the heating uniform during the heating process and improve the heating quality. When the steel ring is placed on the support rod 304, the load-bearing capacity of the support rod 304 can be reduced under the support of the support roller 5, which can improve the stability of the steel ring's placement position. The support seat 6 set at the bottom of the support roller 5 can improve the compressive strength of the support roller 5 under the support of the transport vehicle 2.

[0025] The transport vehicle 2 includes a base plate 201 that is connected to the bottom of the heating box 1. A baffle 203 that is connected to the front opening of the heating box 1 is fixed on the outer side of the base plate 201. The base plate 201 is used to close the bottom of the heating box 1. The bottom of the base plate 201 is also provided with casters 204 to facilitate overall displacement and position adjustment. The baffle 203 can close the opening of the heating box 1 to achieve a closed connection.

[0026] The support member 3 includes a fixed plate 301 fixed on the side wall of the baffle 203. A rotating column 302 that penetrates the baffle 203 is rotatably arranged on one side of the fixed plate 301. A circular plate 303 is fixed at the other end of the rotating column 302. Several support rods 304 that fit against the side of the steel ring are fixed on the other side of the circular plate 303. By fixing the position of the rotating column 302 by the fixed plate 301, it can have the effect of rotation. This allows the support rods 304 on the circular plate 303 to rotate, so as to drive the steel ring to rotate.

[0027] In an embodiment of this utility model, a plurality of limiting protrusions 7 are elastically provided on the wall of the support rod 304, which fit against the two sides of the steel ring. The two sides of the limiting protrusions 7 facing each other are set as V-shaped surfaces 701. The limiting protrusions 7 structure designed on the side wall of the support rod 304 can limit the position of the steel ring. The design of the V-shaped surface 701 can reduce the moving resistance when the steel ring moves, and reduce the impact on the moving operation of the steel ring.

[0028] In the embodiments of this utility model, the left and right side plates of the heating box 1 are integrally formed with a support plate 101 that fits against the bottom of the base plate 201. A support plate 103 for supporting the drive mechanism 4 is fixedly provided on the side of the rear plate of the heating box 1. The support plate 101 can improve the fit between the support plate and the base plate 201 and strengthen the tightness of the connection. The support plate 103 can provide a support position for the drive mechanism 4 to be installed.

[0029] In an embodiment of this utility model, the drive mechanism 4 includes a drive motor 401. The output end of the drive motor 401 is fixedly provided with a rotating rod 402 that penetrates the rear plate of the heating box 1. The other end of the rotating rod 402 is fixedly provided with a plug-in plate 403 that is inserted into a plurality of support rods 304. By controlling the rotating rod 402 through the drive motor 401 to rotate the plug-in plate 403, the connected support rods 304 can be driven to rotate synchronously, thereby controlling the steel ring to rotate during the heating process.

[0030] In the embodiments of this utility model, a limiting strip 102 is fixedly provided on the top of each of the two pallets 101, and the front end of the limiting strip 102 is set as a V-shaped head. A limiting groove 202 that engages with the limiting strip 102 is opened on the bottom side of the bottom plate 201. The limiting effect of the connection between the transport vehicle 2 and the heating box 1 can be further improved by the cooperation of the limiting strip 102 and the limiting groove 202.

[0031] In an embodiment of this utility model, a plurality of fixing blocks 206 are fixedly provided on the top front side of the base plate 201, and the support roller 5 is rotatably disposed between the baffle 203 and the fixing blocks 206; the cooperation between the fixing blocks 206 and the baffle 203 can suspend the support roller 5 below the steel ring, achieving the effect of self-rotation. When the steel ring rotates, the support roller 5 can be driven to rotate through friction, thereby reducing the impact on the surface of the steel ring.

[0032] In an embodiment of this utility model, a plug box 104 is fixedly provided on the top of the heating box 1, and a plug block 205 that plugs into the plug box 104 is fixedly provided on the top of the baffle 203. The plug box 104 and the plug block 205 are connected by a pin limiting connection. The pin limiting connection between the two can limit the position of the transport vehicle 2, thereby improving the stability of the transport vehicle 2 and the heating box 1 during the heating process.

[0033] Working Principle: This embodiment provides a heat treatment device for processing steel ring forgings. In use, the steel rings are first sequentially placed on the outside of several support rods 304. During the pushing process, the limiting protrusions 7 are automatically squeezed and moved into the support rods 304 without affecting the movement of the steel rings. Simultaneously, the limiting protrusions 7 on both sides clamp and limit the steel rings, allowing several steel rings to be placed equidistantly on the support rods 304. After the steel rings are placed, the transport vehicle 2 can be pushed into the heating chamber 1. The bottom wheels 204 of the transport vehicle 2 facilitate position adjustment. The connection between the limiting groove 202 and the support plate 103 restricts the connection between the heating chamber 1 and the transport vehicle 2. Once in position, the bottom plate 201 seals the bottom of the heating chamber 1, and the baffle 203 seals the front opening of the heating chamber 1, achieving a sealed connection. The side end of the support rod 304 is inserted into the inside of the connector plate 403 to complete the connection between the support member 3 and the drive mechanism 4. At the same time, the plug 205 can be inserted into the inside of the connector box 104. With the restraint of the pin, the position of the transport vehicle 2 can be fixed. Then, the heating mechanism set on the top of the heating box 1 can be controlled by the control box set on the right side of the heating box 1 to raise the temperature in the heating chamber. While heating the steel ring, the drive mechanism 4 can be started. Under the operation of the drive motor 401, the connector plate 403 can drive the support rod 304 to rotate, so that the placed steel ring rotates synchronously. The rotating support roller 5 can rotate synchronously under the influence of friction when the steel ring rotates. This can reduce the friction on the surface of the steel ring, so that the steel ring can be heated evenly during the heating process, improve the uniformity of the heat treatment of the steel ring, facilitate subsequent processing operations, and improve the processing quality of the steel ring.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
