Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing technology, and in particular to a pipe fitting heat treatment positioning device. Background Technology

[0002] Heat treatment of pipe fittings is an important process that involves heating, heat preservation, and cooling to change the microstructure and properties of the pipe fittings, thereby improving their strength, hardness, wear resistance, corrosion resistance, eliminating internal stress, and ensuring the dimensional stability and shape accuracy of the pipe fittings to meet different application requirements.

[0003] A patent titled "Positioning Mold for Heat Treatment of Stainless Steel Pipe" has been published in the Chinese Patent Database. The application number is 2020228083203, and the application date is November 27, 2020. This positioning mold for heat treatment of stainless steel pipe includes a base plate, positioning cylinders, and a support block. The base plate has a through positioning hole. The positioning cylinder includes a cylindrical body and a flange located at the end of the body. The body passes through the positioning hole, and the flange abuts against the side of the base plate. The interior of the body is used to insert the stainless steel pipe to be heat-treated. There are several positioning holes evenly distributed along the vertical direction on the base plate. Each positioning hole is connected to a corresponding positioning cylinder. The support block rests against the base plate and is pressed tightly between adjacent positioning cylinders.

[0004] The shortcomings of the above technical solution are: the inner diameter of the positioning cylinder is a fixed-diameter structure, which can only support and position pipe fittings of one diameter. If the pipe fittings are replaced with other diameters, this positioning mold is not applicable. Utility Model Content

[0005] This application provides a pipe fitting heat treatment positioning device to improve the adaptability of the positioning device to pipe fittings of different diameters, thereby improving the versatility of the positioning device.

[0006] This application provides a pipe fitting heat treatment positioning device, including:

[0007] The support has a hole for the pipe fitting to pass through;

[0008] A positioning component, comprising multiple components forming a positioning support structure around the hole, includes: an adjusting component, a connecting seat, and a pressure plate. The adjusting component is adjustable in distance from the center of the hole and connected to the support. The connecting seat is hinged to the adjusting component, and the pressure plate is fixedly connected to the connecting seat.

[0009] The beneficial effects of the above embodiments are as follows: by adjusting the position of the pressure plate by adjusting the adjusting member, the pressure plate can be adapted to pipe fittings with different outer diameters. At the same time, since the connecting seat is hinged to the adjusting member, the pressure plate can be kept in a suitable pressing position on the pipe fitting no matter how the adjusting member rotates, thus improving the versatility of this positioning device for positioning pipe fittings of different diameters.

[0010] Based on the above embodiments, the embodiments of this application can be further improved as follows:

[0011] In one embodiment of this application, it further includes a pad block, which is detachably connected to the support, the pad block extending into a connecting plate, and the positioning assembly being mounted on the connecting plate. The advantage of this step is that by configuring a detachably connected pad block, the assembly and maintenance of the positioning assembly are facilitated.

[0012] In one embodiment of this application, the adjusting member is threadedly connected to the connecting plate. The advantage of this step is that the threaded connection structure allows for stepless adjustment of the position of the adjusting member.

[0013] In one embodiment of this application, it further includes an anti-loosening component, which is connected to the adjusting component and contacts the connecting plate. The beneficial effect of this step is that the anti-loosening component improves the stability of the adjusting component's positioning.

[0014] In one embodiment of this application: one end of the adjusting member is a spherical connecting end, which is hinged to the connecting seat. The beneficial effect of this step is that the spherical structure has good rotational performance, facilitating the adjustment of the pressure plate position.

[0015] In one embodiment of this application, the positioning components are evenly distributed on the same circumference with the axis of the hole as the center line. The beneficial effect of this step is that it can provide uniform support to the outer circumference of the pipe, reducing the deformation of the pipe during high-temperature heat treatment.

[0019] The components include: 1 support, 2 positioning components, 201 adjusting component, 202 connecting seat, 203 pressure plate, 3 pad block, and 4 anti-loosening component. Detailed Implementation

[0020] In this application, unless otherwise expressly specified and limited, the terminology used should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of different terms in this utility model according to the specific circumstances, and the scope of the specific meaning should be limited to achieving the function of this application.

[0021] In the description of this application, it should be understood that the directional terms or positional relationships described are based on the orientation or positional relationships shown in the accompanying drawings, or based on the orientation or positional relationships in actual use, and are only for the purpose of facilitating the description of the contents of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] like Figure 1 , 2 As shown, a pipe fitting heat treatment positioning device includes: a support 1 and a positioning component 2. The support 1 has a hole for the pipe fitting to pass through. The positioning component 2 has multiple components and forms a positioning support structure around the hole. The positioning component 2 includes: an adjusting component 201, a connecting seat 202, and a pressure plate 203. The adjusting component 201 is connected to the support 1 at an adjustable distance from the center of the hole. The connecting seat 202 is hinged to the adjusting component 201. The pressure plate 203 is fixedly connected to the connecting seat 202.

[0023] Specifically, such as Figure 1 As shown, support 1 has a U-shaped structure. Support 1 has two vertical plates and a base plate. The vertical plates are connected to both sides of the base plate. The vertical plates have at least two holes, and the diameter of the holes is larger than the diameter of the largest pipe fitting being positioned.

[0024] Specifically, such as Figure 1 As shown, the pipe fitting heat treatment positioning device also includes: a pad 3, which is detachably connected to the support 1. The pad 3 extends out to a connecting plate, and the positioning assembly 2 is installed on the connecting plate. The pad 3 is bolted to the side of the vertical plate, and the connecting plate is welded to the pad 3. The pad 3 has a through hole coaxially with the corresponding hole, and the positioning assembly 2 is arranged around the through hole.

[0025] Specifically, such as Figure 2As shown, the adjusting component 201 is threadedly connected to the connecting plate. The connecting plate has a threaded hole, the axis of which is perpendicular to the axis of the hole body. The adjusting component 201 is a stud structure, and it is threaded into the threaded hole. The threaded connection structure allows the position of the adjusting component 201 to be infinitely adjustable.

[0026] Specifically, such as Figure 2 As shown, the pipe fitting heat treatment positioning device also includes an anti-loosening component 4, which is connected to the adjusting component 201 and contacts the connecting plate. The anti-loosening component 4 is a nut, such as a hexagonal nut or a hexagonal flange nut, which is threaded onto the adjusting component 201. When the nut is pressed against the connecting plate, it plays an anti-loosening role. Therefore, the positioning stability of the adjusting component 201 can be improved by using the anti-loosening component 4.

[0027] Specifically, such as Figure 2 As shown, one end of the adjusting member 201 is a spherical connecting end, which is hinged to the connecting seat 202. The connecting seat 202 includes an upper pressure cover and a lower pressure cover. The lower pressure cover is bolted to the pressure plate 203, and the upper pressure cover is bolted to the lower pressure cover. The corresponding connecting ends of the upper and lower pressure covers are provided with matching groove structures, so that the connecting end can be rotatably connected between the upper and lower pressure covers. Furthermore, since the spherical structure and the connecting seat 202 form a universal hinge structure, and since the outer diameter of the pipe is smaller than the inner diameter of the hole, the pipe is not necessarily placed completely horizontally when it is placed in the hole. However, the pressure plate 203 connected by the spherical connecting end can change its angle at any angle according to the direction of the pipe, so that even if the pipe is placed at an incline, it can still be stably positioned by the pressure plate 203. Therefore, this structure also improves the ease of use of the positioning device.

[0028] Specifically, such as Figure 2 As shown, four sets of positioning components 2 are connected to the same pad 3. The positioning components 2 are evenly distributed on the same circumference with the hole axis as the center line. This structure can provide uniform support for the outer circumference of the pipe.

[0029] When using this type of pipe fitting heat treatment positioning device, the pipe fitting is passed through the hole, the adjusting component 201 is rotated to change the position of the pressure plate 203 so that the pressure plate 203 contacts the outer wall of the pipe fitting, and then the anti-loosening component 4 is rotated to lock the adjusting component 201 on the connecting plate, thereby stably positioning the pipe fitting on the support 1. When it is necessary to position pipe fittings of different diameters, it is only necessary to loosen the anti-loosening component 4 and change the position of the adjusting component 201. Therefore, this positioning device has good versatility for pipe fittings of different diameters. At the same time, this structure provides uniform support to the outer circumference of the pipe fitting, reducing the amount of deformation of the pipe fitting during the heat treatment process.

[0030] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
