Description

Technical Field

[0001] This utility model relates to the field of pipe forming technology, specifically a fully automatic three-station pipe shrinking machine for loading and unloading. Background Technology

[0002] The pipe shrinking machine is a fully automatic hydraulic pipe end processing machine controlled by an integrated touch screen for expanding and shrinking pipe ends under normal conditions. By changing the mold, it can perform pipe end processing such as expansion, shrinking, bulging, and upsetting. The machine tool can be operated manually, inching, or automatically according to user needs. It consists of main parts such as an oil tank, bed, slide block, main cylinder, mold core rod (optional), limit cylinder, clamping cylinder, clamping mold, axial positioning cylinder, and axial positioning angle iron. A search revealed the authorized announcement number CN208019297U. A Chinese patent discloses a pipe shrinking machine, including a base and a frame. The frame is mounted on the base. One side of the frame has a clamping device for clamping pipe fittings, and the other side has a pipe shrinking device for processing the ends of the pipe fittings. A positioning device is located on the top of the frame. The clamping device has a first driving device, the pipe shrinking device has a second driving device, and the positioning device has a third driving device. The pipe shrinking device includes a mounting base, and the front end of the mounting base has one or more pipe shrinking molds for forming the ends of pipe fittings. Each pipe shrinking mold is detachably connected to the mounting base. This pipe shrinking machine can clamp and process pipe fittings that require multiple processing steps in one operation, with high processing efficiency, simple operation steps, and low time and labor costs.

[0003] However, in actual use, due to structural limitations, the pipe fittings can only be picked up and put in from the same position before and after processing. This means that the device can only process the pipe fittings one by one, which results in low work efficiency and is not conducive to the shrinking of large batches of pipe fittings. Utility Model Content

[0004] To address the problem of low working efficiency in existing tube shrinking machines, this utility model provides a fully automatic three-station tube shrinking machine with loading and unloading.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A fully automatic three-station tube shrinking machine includes a worktable and a feeding rack. The feeding rack is installed on one side of the worktable. On the side of the worktable near the feeding rack, a tube shrinking mechanism, a clamping mechanism, a conveying mechanism, and a limiting component are respectively installed. The conveying mechanism includes a placement plate. A second slide rail is installed on the top surface of the placement plate. Slide frames are slidably connected to both sides of the top surface of the second slide rail. A support plate is inserted between the two slide frames. A third hydraulic cylinder is installed on one side of the placement plate. The output end of the third hydraulic cylinder is connected to one side of the slide frame. A fourth hydraulic cylinder is installed at the top inside the worktable. The output end of the fourth hydraulic cylinder is connected to the bottom surface of the placement plate. A discharge port is provided on the top surface of the worktable away from the feeding rack. The bottom end of the discharge port is connected to a discharge hopper.

[0007] Furthermore, the feeding rack includes a base frame, a linear motor is mounted on the top surface of the base frame, side plates are mounted on the linear motor and the top surface of the base frame respectively, a conveyor chain is mounted on an adjacent side of the two side plates respectively, and several support blocks are equidistantly mounted on the outer wall of the conveyor chain.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by installing and using a linear motor, it can drive one of the side plates to move in position, thereby adjusting the distance between the two sets of side plates, so that the feeding rack can be used for pipes of different lengths.

[0009] Furthermore, a drive housing is installed on one side of the outer wall of the side plate. The drive housing includes a motor, a pair of synchronous pulleys and a synchronous belt. The motor is installed on one side of the side plate. The output end of the motor is connected to the synchronous pulleys. The pair of synchronous pulleys are connected by a synchronous belt. One of the synchronous pulleys is connected to the conveyor chain.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the kinetic energy output of the motor enables the synchronous pulley and synchronous belt to operate, thereby driving the conveyor chain to move and driving the support block to move, which facilitates the feeding and conveying of the pipes placed on the support block.

[0011] Furthermore, the tube shrinking mechanism includes a fixed base, the top surface of the worktable is equipped with the fixed base, a first hydraulic cylinder is installed on one side of the fixed base, the output end of the first hydraulic cylinder is connected to a mounting bracket, and a tube shrinking die head is installed on one side of the mounting bracket.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by pushing the mounting bracket through the output end of the first hydraulic cylinder, the mounting bracket can drive the tube shrinking die head to adjust to the designated position until the inside of the tube shrinking die head contacts one end of the tube.

[0013] Furthermore, the bottom end of the mounting bracket is slidably connected to a first slide rail, which is fixedly installed on the top surface of the workbench.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the installation and use of the first slide rail makes the sliding of the mounting bracket on the worktable smoother.

[0015] Furthermore, the clamping mechanism includes a frame and a square frame. The frame and the square frame are respectively installed on both sides of the top surface of the worktable. A second hydraulic cylinder is installed on the top surface of the frame. The output end of the second hydraulic cylinder extends into the interior of the frame and is connected to an upper clamping block. A lower clamping block is installed on the top surface of the square frame. The lower clamping block is located directly below the upper clamping block.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by installing and using the second hydraulic cylinder, it can press down the upper clamping block, which facilitates the upper and lower clamping blocks to fix and clamp the pipe fitting.

[0017] Furthermore, the frame has an opening on the side near the loading rack.

[0018] The advantage of adopting the above-mentioned further solution is that, by setting the opening, it is convenient for the pipes conveyed on one side of the feeding rack to directly enter the interior of the clamping mechanism.

[0019] Furthermore, the limiting component includes a limiting frame, which is installed on the top surface of the worktable. A threaded cylinder is inserted and connected to one side of the limiting frame. A rotating rod is threadedly connected inside the threaded cylinder. One end of the rotating rod passes through the threaded cylinder and is connected to a baffle.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by rotating the swivel, one end of it can drive the baffle to advance in a spiral until the pipe is restricted to a specified position.

[0021] Furthermore, a control panel is installed on one side of the top surface of the workbench.

[0022] The advantage of adopting the above-mentioned further solution is that the installation and use of the control panel makes it easier to operate the tube shrinking machine.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This fully automatic three-station tube shrinking machine, through the coordinated use of a tube shrinking mechanism, a clamping mechanism, a conveying mechanism, a limiting component, and a discharge hopper, enables the tube shrinking machine to have a three-station structure. This allows tubes to be loaded and unloaded at different positions, thereby improving the working efficiency of the tube shrinking machine. Specifically, the corresponding tube is conveyed to the clamping mechanism by the loading rack and fixed inside the clamping mechanism. Then, the tube shrinking mechanism pushes the tube to shrink one end. At the same time, the tube is lifted by the pallet in the conveying mechanism, allowing the tube to be transported to a specific position. Then, the position is moved by the pull of the slide by the output end of the third hydraulic cylinder, so that the tube on the pallet can continue to be conveyed after the tube shrinking process is completed. The fourth hydraulic cylinder lifts the placement plate, raising the tube to a certain height, so that it slides into the discharge port and is discharged through the discharge hopper.

A conveyor chain 2004 is respectively mounted on the adjacent side of the two side plates 2003. Several support blocks 2005 are equidistantly mounted on the outer wall of the conveyor chain 2004. Through the installation and use of the linear motor 2002, it can drive one of the side plates 2003 to move in position, thereby adjusting the distance between the two sets of side plates 2003, so that the loading rack 200 can be used for pipes of different lengths.

The synchronous pulleys and the synchronous belt operate through the kinetic energy output of the motor, thereby driving the conveyor chain 2004 to move and driving the support block 2005 to move, so as to facilitate the feeding and conveying of the pipes placed on the support block 2005. The pipe shrinking mechanism 300 includes a fixed seat 3001. The fixed seat 3001 is installed on the top surface of the worktable 100. A first hydraulic cylinder 3002 is installed on one side of the fixed seat 3001. The output end of the first hydraulic cylinder 3002 is connected to a mounting frame 3004. A pipe shrinking die head 3005 is installed on one side of the mounting frame 3004. The mounting frame 3004 is pushed by the output end of the first hydraulic cylinder 3002, so that the mounting frame 3004 can drive the pipe shrinking die head 3005 to adjust to a specified position until the inside of the pipe shrinking die head 3005 contacts one end of the pipe. Example 3

[0037] Please see Figures 1-7As an embodiment of this utility model, further, the bottom end of the mounting bracket 3004 is slidably connected to a first slide rail 3003. The first slide rail 3003 is fixedly installed on the top surface of the workbench 100. Through the installation and use of the first slide rail 3003, the sliding of the mounting bracket 3004 on the workbench 100 is made smoother. The clamping mechanism 400 includes a frame 4001 and a square frame 4004. The frame 4001 and the square frame 4004 are respectively installed on both sides of the top surface of the workbench 100. A second hydraulic cylinder 4002 is installed on the top surface of the frame 4001. The output end of the second hydraulic cylinder 4002 extends into the interior of the frame 4001 and is connected to an upper clamping block 4003. A lower clamping block 4005 is installed on the top surface of the square frame 4004. The lower clamping block 4005 is located directly below the upper clamping block 4003. Through the installation and use of the second hydraulic cylinder 4002, it can press down the upper clamping block 4003 to facilitate the upper clamping block 4003. Clamping block 4003 and lower clamping block 4005 securely hold the pipe fitting. Frame 4001 has an opening 4006 on the side near the loading rack 200. The opening 4006 allows the pipe fitting conveyed from the loading rack 200 to directly enter the clamping mechanism 400. The limiting component 600 includes a limiting frame 6001. The limiting frame 6001 is installed on the top surface of the workbench 100. A threaded cylinder 6002 is inserted and connected to one side of the limiting frame 6001. A rotating rod 6003 is threadedly connected inside the threaded cylinder 6002. One end of the rotating rod 6003 passes through the threaded cylinder 6002 and is connected to a baffle 6004. By rotating the rotating rod 6003, one end can drive the baffle 6004 to spiral forward until the pipe fitting is restricted to a designated position. A control panel 700 is installed on one side of the top surface of the workbench 100. The installation and use of the control panel 700 facilitates the operation of the pipe shrinking machine.

[0038] Specifically, the working principle of this fully automatic three-station tube shrinking machine is as follows: First, check the structure of the shrinking machine for integrity. After ensuring the structure is intact, place the tube onto the loading rack 200. The linear motor 2002 drives one of the side plates 2003 to adjust its position, thereby adjusting the distance between the two sets of side plates 2003. This allows the loading rack 200 to accommodate tubes of different lengths. The motor's kinetic energy output drives the synchronous pulley and belt, which in turn drives the conveyor chain 2004, moving the support block 2005. This facilitates the loading and conveying of the tubes placed on the support block 2005. Then, by activating the second hydraulic cylinder 4002, its output end presses down on the upper clamping block 4003, allowing the upper and lower clamping blocks 4003 to secure the tube. The first hydraulic cylinder 3002 is activated, causing its output end to push the mounting frame 3004. This causes the mounting frame 3004 to adjust the tube shrinking die 3005 to the designated position until the inside of the tube shrinking die 3005 contacts one end of the tube. The installation and use of the first slide rail 3003 makes the sliding of the mounting frame 3004 on the worktable 100 smoother. The support plate 5004 in the conveying mechanism 500 lifts the tube, allowing it to be transported to the correct position. The output end of the third hydraulic cylinder 5005 pulls the slide 5003 to move it, allowing the tube on the support plate 5004 to continue to be transported after the tube shrinking process is completed. The fourth hydraulic cylinder 5006 lifts the placement plate 5001, raising the tube to a higher height so that it slides into the discharge port and is discharged through the discharge hopper 800.
