Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipe expander technology, specifically a hydraulic pipe expander with a pipe protection structure. Background Technology

[0002] Pipe fittings often require pipe end expansion during manufacturing to facilitate installation and connection. This expansion is achieved using a hydraulic pipe expander, which uses hydraulic pressure to enlarge the opening of a thin pipe. A search revealed existing technology publication CN202222026800.3, which describes a hydraulic pipe expander for preventing pipe wrinkling. The expansion machine features a fixed frame on top of a processing table with symmetrically arranged processing grooves. Limiting components are installed within these grooves and are positioned outside the workpiece. A lead screw is located on one side of the fixed frame, with both ends connected to the top of the processing table via fixed plates. One end of the lead screw is connected to a motor, and a slider is attached to the lead screw. A fixed plate is positioned on top of the slider, and a hydraulic cylinder is mounted on the fixed plate. One end of the hydraulic cylinder is connected to the expansion head via a mounting plate.

[0003] In summary: In the above cases, when the pipe body is processed by the hydraulic pipe expander, there is no limiting structure on one side of the pipe body. The pipe body may slide to one side under force, which will affect the normal processing. Furthermore, the sliding of the pipe body under force can easily cause sliding damage to the outer wall of the pipe body. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a hydraulic pipe expander with a pipe protection structure. This solves the problem mentioned in the background art where, when processing pipes with a hydraulic pipe expander, one side of the pipe is not equipped with a limiting structure, and the pipe may slide to one side under force, thus affecting normal processing. Furthermore, the sliding of the pipe under force can easily cause sliding damage to the outer wall of the pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic pipe expander with a pipe protection structure, comprising a hydraulic pipe expander structure, wherein a clamping and protective structure is fixed on the hydraulic pipe expander structure;

[0006] The hydraulic expansion structure includes an operating platform with a fixed mounting groove, and a guide block with a sliding groove is installed on one side above the operating platform. At the same time, a connecting through hole is opened through the surface of the guide block.

[0007] The guide block is connected to the adjusting slider via a sliding groove, and the surface of the adjusting slider is also provided with another connecting through hole. The adjusting slider is limited by a connecting rod passing through the connecting through hole, and a backing plate is fixedly installed on the top of the adjusting slider.

[0008] By adopting the above technical solution, the guide blocks are set to provide a sliding support.

[0009] Preferably, a multi-section adjusting cylinder is fixedly installed on one side of the operating platform via a fixing plate, and an expanding pipe column is fixedly installed at the output end of the multi-section adjusting cylinder. At the same time, a through-hole vertical plate is fixedly installed through the expanding pipe column, and a roller plate is fixed at the bottom of the through-hole vertical plate.

[0010] By adopting the above technical solution, synchronous drive adjustment is achieved through the setting of roller plates.

[0011] Preferably, the clamping and protective structure includes a synchronous cylinder fixedly installed inside the lower part of the operating machine via a fixing frame, and a lower clamping module is fixedly installed at the output end of the synchronous cylinder, with a rubber pad laid and fixedly installed on the inner side of the lower clamping module.

[0012] By adopting the above technical solution, the rubber pads used provide isolation and clamping protection.

[0013] Preferably, the lower clamping module is driven and adjusted relative to the upper clamping module directly above it, and another rubber pad is laid and fixedly installed on the inner side of the upper clamping module. At the same time, the upper clamping module is fixedly installed on the inner side of the connecting frame through the connecting frame and another synchronous cylinder. The connecting frame is fixedly installed on the operating table.

[0014] By adopting the above technical solution, the connecting frame is used to achieve fixed installation.

[0015] Preferably, the adjusting slider and the backing plate are connected in a "T" shape.

[0016] By adopting the above technical solution, the adjustable slider is used to fix and open the connection.

[0017] Preferably, the lower clamping module and the upper clamping module are arranged in an alternating manner.

[0018] By adopting the above technical solution, the upper clamping module is used to achieve lifting and adjustment.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this hydraulic pipe expander with a pipe protection structure,

[0020] (1) This case solves the problem in the above case where, when processing the pipe body with a hydraulic pipe expander, one side of the pipe body is not equipped with a limiting structure, and the pipe body may slide to one side under force, thus affecting normal processing. Furthermore, when the pipe body slides under force, it is easy to cause sliding damage to the outer wall of the pipe body. When the pipe body needs to be expanded, the operator uses the clamping and protective structure to clamp and fix the pipe body. After the operator pushes the abutment plate to abut against one end of the pipe body, the operator uses the connecting rod to adjust the limiting position of the abutment plate through the connecting hole, thus facilitating the above-mentioned problems in the process of expanding the pipe body.

[0021] (2) By setting up a clamping protection structure, the above problems are solved. When the pipe needs to be expanded, the operator manually places the pipe between the upper clamping module and the lower clamping module through the connecting frame. When the operator watches the synchronous cylinder work, the pipe is clamped and fixed by the upper clamping module and the lower clamping module. When the pipe is clamped and fixed, the rubber pads provide clamping protection to the surface of the pipe. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a hydraulic pipe expander with a pipe protection structure, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a hydraulic expansion structure 1, which includes an operating platform 101 with a fixed mounting groove. A guide block 102 with a sliding groove 103 is mounted on one side of the operating platform 101. A connecting through hole 104 is formed on the surface of the guide block 102. The guide block 102 is slidably connected to an adjusting slider 105 via the sliding groove 103. Another connecting through hole 104 is also formed on the surface of the adjusting slider 105. The adjusting slider 105 is limited by a connecting rod 106 passing through the connecting through hole 104. A backing plate 107 is fixedly mounted above the adjusting slider 105, and the adjusting slider 105 is connected to the backing plate 107. The connection shape is arranged in a "T" structure. When the connection shape of the two components is arranged in a "T" structure, it not only reflects the fixed installation of the two components, but also reflects the synchronous force-driven adjustment of the two components. Furthermore, the connection shape of the two components in a "T" structure reflects the axial symmetry of the two components in both longitudinal and axial directions. Moreover, the connection shape of the two components in a "T" structure reflects the practicality of the fixed installation. The above-mentioned components constitute a drive sliding adjustment structure, which effectively and synchronously changes the synchronous sliding interval distance of the abutment plate 107.

[0031] Furthermore, in the above scheme, a multi-section adjusting cylinder 108 is fixedly installed on one side of the operating platform 101 by a fixing plate, and an expanding pipe column 109 is fixedly installed at the output end of the multi-section adjusting cylinder 108. At the same time, a through-hole vertical plate 1010 is fixedly installed through the expanding pipe column 109, and a roller plate 1011 is fixed at the bottom of the through-hole vertical plate 1010.

[0032] like Figure 4 , Figure 5 and Figure 6As shown, a clamping and protective structure 2 is fixed on the hydraulic expansion structure 1. The clamping and protective structure 2 includes a synchronous cylinder 201 fixedly installed inside the lower part of the operating platform 101 via a fixing bracket 202. A lower clamping module 203 is fixedly installed at the output end of the synchronous cylinder 201. A rubber pad 204 is laid and fixedly installed on the inner side of the lower clamping module 203. The lower clamping module 203 is driven and adjusted relative to the upper clamping module 205 directly above it. Another rubber pad 204 is laid and fixedly installed on the inner side of the upper clamping module 205. At the same time, the upper clamping module 205 is connected to the connecting bracket 20. 6 and another synchronous cylinder 201 are fixedly installed inside the connecting frame 206. The lower clamping module 203 and the upper clamping module 205 are arranged in an alternating manner. When the two are arranged in an alternating manner, it not only reflects the synchronous relative lifting and lowering drive adjustment of the two, but also reflects that the above components can clamp and fix pipes of different diameters in an alternating manner. When the shape of a single module is a kitchen knife structure, the above components can effectively achieve a synchronous clamping and fixing effect on the pipes when they are arranged in a kitchen knife structure. The connecting frame 206 is fixedly installed on the operating table 101.

[0033] In the above scheme, when the pipe needs to be expanded, the operator manually places the pipe between the lower clamping module 203 and the upper clamping module 205 through the connecting frame 206. During the operation of the synchronous cylinder 201, the operator clamps and fixes the pipe through the lower clamping module 203 and the upper clamping module 205. After the pipe is clamped and fixed, the operator pulls the connecting rod 106 and the connecting through hole 104 to separate them by force, and pushes the abutment plate 107 to contact one end of the pipe. The operator then uses the connecting rod 106 to connect through the connecting through hole 104 to limit the connection of the abutment plate 107. Then, the operator controls the multi-section adjusting cylinder 108 to drive the expansion column 109 to move, thereby expanding one end of the pipe.
