[0001] The utility model relates to the field of hydraulic pipe processing equipment, in particular to an inner diameter processing equipment for hydraulic pipe joints. Background Technique

[0002] The inner diameter processing of hydraulic pipe joints is an important link in the manufacturing process of hydraulic pipe joints, which is directly related to the sealing performance, connection strength of the joints and the overall performance of the hydraulic system.

[0003] Among them, as a professional equipment, the pipe pressing machine is widely used in the processing of various pipes, including the inner diameter processing of hydraulic pipe joints. The pipe pressing machine is driven by hydraulic or electric power, and with precise molds and control systems, it can achieve high-precision inner diameter processing, which is crucial for the sealing performance and performance of hydraulic pipe joints. However, during the pipe pressing process, the pipe fittings enter the processing through the mold opening. If the pipe fittings outside the mold are not properly fixed, they may collide during the operation due to lack of support, resulting in deviation, which in turn affects the stability of the pipe fittings inside the mold. For this reason, an inner diameter processing equipment for hydraulic pipe joints is proposed. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides an inner diameter processing equipment for hydraulic pipe joints. By arranging a positioning end plate directly in front of the opening of the pipe pressing mold to position the pipe fittings outside the inner diameter processing body, the limiting convex ring performs a limiting operation when the positioning end plate is positioning. The support frame plate is arranged at the middle part of the bottom of the positioning end plate, which can support the whole positioning end plate. With this design, while fixing the pipe fittings outside the pipe pressing mold, it can support the pipe fittings to prevent collisions during the processing, which are likely to cause deviation problems, and can also improve the stability.

[0005] In order to solve the above technical problems, the utility model solves the problem that the inner diameter processing equipment for hydraulic pipe joints cannot position the pipe fittings outside the mold when in use through the following technical solutions.

[0012] Preferably, a connecting plate is provided at the top of the support frame plate, which contacts the bottom of the positioning end - plate and is connected by bolts.

[0013] Preferably, an adjusting and fixing structure is provided between the support frame plate and the inner - diameter processing machine body. The adjusting and fixing structure includes a positioning frame body, a movable plate, and a compression spring.

[0036] Please refer to Figure 1 - Figure 7 , a hydraulic pipe joint inner diameter processing device, including a pipe pressing die 101 arranged on an inner diameter processing body 1. A positioning end plate 2 with a limiting convex ring 3 is arranged in front of the pipe pressing die 101 for positioning. The size of the opening at one end of the limiting convex ring 3 is the same as that of the corresponding pipe pressing die 101. A support frame plate 5 is arranged at the bottom of the positioning end plate 2 for support.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6, the inner diameter processing equipment of the present application mainly consists of a structure combination such as an inner diameter processing body 1 and a pipe pressing die 101. The pipe pressing die 101 has an opening through which a pipe fitting can be fed. At this time, a positioning end plate 2 is arranged directly in front of the opening of the pipe pressing die 101, which can position the end face of the pipe fitting outside the inner diameter processing body 1 when one end of the pipe fitting is fed in. The positioning end plate 2 and the limiting collar 3 are integrally structured. When the positioning end plate 2 positions one end of the machine head, it is placed inside the limiting collar 3 for limiting operation. The support frame plate 5 is arranged in the middle of the bottom end of the positioning end plate 2 to support the whole positioning end plate 2. With this design, while fixing the pipe fitting outside the pipe pressing die 101, it can support the pipe fitting to prevent collision during the processing, which is likely to cause deviation, improve stability, and also avoid affecting the processing effect of the pipe fitting in the die.

[0038] In the present application, a stabilizing pad 4 is also provided. The stabilizing pad 4 is designed with a rubber material and is laid flat on the side of the positioning end plate 2 that can be fixed and can come into contact with the pipe fitting. Anti-slip lines are also provided on the side in contact with the pipe fitting. In this way, when the positioning end plate 2 fixes the pipe fitting, the friction force of the contact surface between the two is increased, making the connection more stable.

[0039] In the present application, a plug-in structure 401 and a preset jack 201 are also provided. A number of plug-in structures 401 and preset jacks 201 are provided, and the numbers of both are equal. Among them, the plug-in structure 401 is evenly glued on the side of the stabilizing pad 4 in contact with the positioning end plate 2, and the preset jacks 201 are evenly opened around the positioning end plate 2. When the stabilizing pad 4 is laid flat on the positioning end plate 2, it can correspondingly drive the plug-in structure 401 to penetrate into the inside of the preset jack 201. While being inserted, the installation of the stabilizing pad 4 is completed. In this way, when the stabilizing pad 4 is worn, it can be replaced in time.

[0040] It should also be noted that the inserted end of the plug-in structure 401 has elasticity. When it is inserted into the inside of the preset jack 201, it will be mutually extruded with its inner wall. In this way, after penetrating into the inside of the preset jack 201, it will deform, and further positioning treatment is performed on the connection between the plug-in structure 401 and the preset jack 201 to ensure the firmness of the connection.

[0041] In the present application, a handle 502 is also provided. The handle 502 is fixedly installed on the upper part of the outer wall of the support frame plate 5. Rubber convex layers are glued both inside and outside the handle 502, which is convenient for pulling the whole support frame plate 5 to move later and brings convenience to the operation.

[0042] A connecting plate 501 is also provided in this application. The connecting plate 501 and the support frame plate 5 are designed as an integral structure, and its area design is equal to the bottom of the positioning end plate 2. After the two are butted, they can be fixed by bolts, so as to facilitate the subsequent operation of disassembling and replacing the whole positioning end plate 2 according to the fixing requirements.

[0043] A adjusting and fixing structure is also provided in this application. The adjusting and fixing structure is mainly composed of a positioning frame 6, a movable plate 601 and a compression spring 602. This structure is arranged between the support frame plate 5 and the inner diameter processing body 1. When the support frame plate 5 supports the positioning end plate 2, the distance between the fixed pipe fittings of the positioning end plate 2 can be adjusted. The positioning frame 6 is arranged on the outer wall of the inner diameter processing body 1, the movable plate 601 is fixedly installed on the inner wall of the support frame plate 5, and the positioning frame 6 has an opening so that the movable plate 601 can extend into its interior for movement. The two are connected by a compression spring 602, and the compression spring 602 itself has elasticity. At this time, just pull the support frame plate 5 outwards, then the movable plate 601 can be driven to move inside the positioning frame 6, so as to adjust the distance between the positioning end plate 2 and the fixed pipe fittings. After the pipe fitting is placed between the pipe pressing die 101 and the positioning end plate 2, stop the acting force, so that the compression spring 602 generates elastic deformation, and then the positioning operation can be carried out, improving the applicability.

[0044] A stable slot 8 is also provided in this application. The stable slot 8 is opened on the outer wall of the inner diameter processing body 1, so that the end of the positioning frame 6 without an opening can be inserted therein, so as to position the overall structure on the positioning frame 6 on the inner diameter processing body 1, so that the positioning end plate 2 and the pipe pressing die 101 are in a relatively aligned state.

[0045] A first magnetic attraction structure 9 and a second magnetic attraction structure 901 are also provided in this application. The first magnetic attraction structure 9 is glued to the inner wall of the stable slot 8, and the second magnetic attraction structure 901 is glued to the side of the second magnetic attraction structure 901 without an opening. At this time, when the positioning frame 6 is completely inserted into the stable slot 8 for positioning, magnetic attraction is generated between the first magnetic attraction structure 9 and the pipe pressing die 101, thereby further improving the stability of the positioning frame 6 during connection.

[0046] An external frame plate 7 is also provided in this application. The external frame plate 7 is fixed on the outer periphery of the positioning frame 6. When the positioning frame 6 is inserted into the stable slot 8, it is limited on the outer wall of the inner diameter processing body 1. The four corners of the surface of the external frame plate 7 in contact with the inner diameter processing body 1 are fastened by bolts. When connecting the external frame plate 7 and the inner diameter processing body 1 in this way, the overall structure of the positioning frame 6 is installed on the inner diameter processing body 1, which is convenient for disassembly and relocation later during installation.

[0047] Those skilled in the art should understand that the embodiments of the present utility model described above and shown in the accompanying drawings are only examples and do not limit the present utility model. The object of the present utility model has been fully and effectively achieved. The functions and structural principles of the present utility model have been demonstrated and explained in the embodiments.
