Description

Technical Field

[0001] The utility model relates to the technical field of plastic-lined composite pipe processing, in particular to a plastic-lined composite pipe casing machine. Background Technique

[0002] The plastic-lined steel pipe uses galvanized seamless steel pipe and welded steel pipe as the base pipe. After removing the welding ribs on the inner wall, a food-grade polyethylene (PE) pipe with the same diameter as the inner diameter of the galvanized pipe is lined, and finally it is formed after pressurizing and heating for a certain time, and is widely used in the cold and hot water supply systems of various buildings.

[0003] When the plastic-lined steel pipe is produced and processed, a casing machine can be used for composite production. However, during production, the feeding port of the casing machine is relatively high, and pipes such as steel pipes need to be carried by personnel for loading and unloading. Moreover, after the steel pipe is formed in the casing machine, it also needs to be manually taken out by personnel for material taking, which affects the loading and unloading operation, and the personnel operation is cumbersome and affects the later processing operation, so it still needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a plastic-lined composite pipe casing machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A plastic-lined composite pipe casing machine, including an installation base, a frame, a fixing frame, a casing machine body and a clamping frame one,

[0007] A driving mechanism two is installed inside the limit frame one, and a lead screw two is arranged on the output shaft of the driving mechanism two;

[0008] The top surface of the frame is welded with an L-shaped guide frame one and an L-shaped guide frame two;

[0009] The bottom surface of the casing machine body is welded with a fixing frame;

[0010] A driving mechanism one is installed on the side surface of the fixing frame, and a lead screw one is arranged on the output shaft of the driving mechanism one;

[0011] The bottom surface of the clamping frame one is welded with a T-shaped guide frame;

[0012] A hydraulic rod is installed on the top surface of the casing machine body, and a clamping frame two is arranged on the output shaft of the hydraulic rod.

[0013] Preferably, the L-shaped guide frame one is sleeved inside the limit frame two and sleeved on the guide rod. When the L-shaped guide frame one is sleeved inside the limit frame two and sleeved on the guide rod for limit installation, one end of the frame can be limited.

[0014] Preferably, the second L-shaped guide frame is sleeved in the first limiting frame, and the second L-shaped guide frame is installed on the second lead screw by means of threads. The second L-shaped guide frame is sleeved in the first limiting frame for limiting. When limiting, the second L-shaped guide frame is installed on the second lead screw by means of threads, so as to limit the other end of the frame.

[0015] Preferably, bearings are installed at both ends of the inner wall of the frame, and guide shafts are installed in the bearings. By installing the guide shafts in the bearings, the guide shafts can be used to place steel pipes and plastic pipes respectively.

[0016] Preferably, support blocks are welded to the bottom end surface of the installation base. There are four support blocks in total, and the four support blocks are distributed in a rectangular array relative to the installation base. The installation base can be installed and supported by the support blocks.

[0017] Preferably, an installation frame is installed on the bottom end surface of the casing machine body, and the bottom end surface of the installation frame is welded to the installation base. The casing machine body can be installed and fixed on the installation base through the installation frame.

[0018] Preferably, the T-shaped guide frame is sleeved in the fixed frame, and the T-shaped guide frame is installed on the first lead screw by means of threads.

[0019] Preferably, a first limiting rod is welded to the top end surface of the casing machine body. The bottom end surface of the first limiting rod is sleeved with a second limiting rod, and the bottom end surface of the second limiting rod is installed on the second clamping frame. By installing the bottom end surface of the second limiting rod on the second clamping frame, when the second clamping frame is pushed by the hydraulic rod, the second limiting rod is sleeved in the first limiting rod for limiting and guiding.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] 1. The present invention utilizes a frame to facilitate the placement of steel and plastic pipes, respectively, on the guide shafts during the casing operation. Once placed, the L-shaped guide frame is inserted into the second limit frame and onto the guide rod, effectively limiting one end of the frame during the installation. Simultaneously, the second L-shaped guide frame is inserted into the first limit frame, effectively limiting the other end of the frame. Notably, the second L-shaped guide frame is threaded onto the second screw rod. This allows the operator to activate the second drive mechanism and rotate the second screw rod. Depending on the direction of rotation of the second screw rod, the frame can move up and down, driving the steel and plastic pipes, respectively, to the feed port of the casing machine. Once at the feed port, the operator can first push the steel pipe, leveraging the thrust provided by the guide shaft, into the casing machine. Clamping frame one provides support during the steel pipe's entry. Once support is achieved, the operator can activate the hydraulic lever and push clamping frame two to clamp the supported steel pipe. After clamping is completed, the operator can load the plastic pipe again and push it into the steel pipe to form a plastic-lined composite pipe, thereby meeting the subsequent loading and processing needs and avoiding the inconvenience caused by manual loading and unloading.

[0022] 2. The utility model is provided with a casing machine body. After the personnel complete the casing operation on the plastic-lined composite pipe, in order to prevent the plastic-lined composite pipe from being difficult to remove in the casing machine body, the personnel can start the hydraulic rod to push the clamping frame 2 to move upward, thereby loosening the clamping of the plastic-lined composite pipe. After loosening, the T-shaped guide frame is sleeved in the fixed frame to realize the limiting function. During the limiting process, the T-shaped guide frame is installed on the screw rod 1 through a thread, so that the personnel can start the driving mechanism 1 to drive the screw rod 1 to rotate. According to the rotation direction of the screw rod 1, the T-shaped guide frame can move left and right, thereby driving the clamping frame 1 to move in the casing machine body. In this way, the plastic-lined composite pipe on the clamping frame 1 in the casing machine body can be smoothly taken out, avoiding the inconvenience caused by probing into the material.
