Description

Technical Field

[0001] This application relates to the field of pipe end forming machines, and more particularly to a pipe end forming machine with convenient replacement parts. Background Technology

[0002] A pipe end forming machine is a type of equipment used for processing pipe fittings such as flaring, locking, and shrinking.

[0003] The pipe end forming machine for pipe shrinking includes a frame, a clamping assembly, and a forming assembly. The clamping assembly includes a drive cylinder, a moving block, a fixed block, and two clamping accessories. The fixed block is fixedly mounted on the frame. The drive cylinder is vertically mounted, and the moving block is located directly above the fixed block. The drive cylinder is used to move the moving block vertically. The two clamping accessories correspond to the moving block and the fixed block, respectively. The clamping assembly is installed on the fixed block or the moving block by bolts. When the moving block abuts against the fixed block, the clamping accessories form a groove for clamping the pipe fitting. The forming assembly includes a forming block and a forming cylinder. The forming block is close to or away from one end of the pipe fitting. The forming cylinder drives the forming block to move. The forming block is used to shrink one end of the pipe fitting.

[0004] When the size of the pipe fitting changes or the pipe shrinkage size is adjusted, the clamping accessories need to be replaced. However, one of the clamping accessories is located below the moving block and is inconvenient to operate by bolt connection. It requires the operator to lower their posture and tilt their head back to operate, and it is also inconvenient for a single person to operate. This makes the replacement of the clamping accessories cumbersome and the work efficiency low. Utility Model Content

[0005] To facilitate the adjustment of clamping accessories and improve the efficiency of changing clamping accessories, this application provides a pipe end forming machine with convenient replacement accessories.

[0006] This application provides a tube end forming machine that facilitates the replacement of accessories, employing the following technical solution: A pipe end forming machine with convenient replacement parts includes a frame, a clamping assembly, and a forming assembly for shrinking the pipe end. The clamping assembly includes a drive cylinder, a fixed block, a moving block, two clamping accessories, a movable block, and a limiting member. The fixed block is mounted on the frame. The drive cylinder is vertically mounted on the frame. The movable block is mounted on the piston rod of the drive cylinder. The moving block is rotatably connected to the movable block along a horizontal rotation axis. The two clamping accessories are respectively bolted to the fixed block and the moving block. When the moving block is on one side of the movable block, the moving block is directly above the fixed block. When the moving block is above the movable block, the clamping accessory corresponding to the moving block is located on the upper side of the moving block. The limiting member is used to keep the moving block abutting against the side wall of the movable block. When the fixed block and the moving block abut against each other, the two clamping accessories form a groove for clamping the pipe.

[0007] By adopting the above technical solution, the moving block can rotate around the horizontal rotation axis of the movable block. When it is necessary to replace the clamping parts on the moving block, the moving block can be rotated to move the clamping parts from directly above the fixed block to the upper side of the moving block. There is no need for the staff to lower their posture and tilt their heads up to operate. A single person can easily complete the bolt removal and installation of the clamping parts, which changes the operation of replacing clamping parts and improves work efficiency. At the same time, the limiting parts ensure the stable contact between the moving block and the movable block, ensuring the structural reliability when clamping the pipe fittings. The two clamping parts form a matching hole groove to ensure the clamping effect of the pipe fittings to meet the needs of pipe shrinking processing.

[0008] Optionally, the limiting component includes a movable rod and two limiting rods. The length direction of the movable rod is parallel to the rotation axis of the movable block. The movable rod slides on the movable block in a horizontal direction that is close to or away from the movable block. The length direction of the limiting rod is parallel to the moving direction of the movable rod. The two limiting rods are respectively disposed at both ends of the movable rod. Two limiting plates are disposed on the corresponding side walls of the movable block. The limiting plates are distributed in a vertical direction, and the limiting rod is located between the two limiting plates.

[0009] By adopting the above technical solution, the limiting component drives two limiting rods to move via a moving rod. The limiting rods are engaged between two vertically distributed limiting plates on both sides of the moving block, which can accurately limit the rotation state of the moving block from both sides, ensuring that the moving block can remain stable in the working position and avoiding accidental rotation of the moving block from affecting the processing accuracy. The structure is simple and the limiting is reliable, further ensuring the stability of the equipment and the convenience of replacing parts.

[0010] Optionally, the clamping assembly further includes two anti-detachment components, with two anti-detachment blocks corresponding to two limiting rods. Each anti-detachment component includes an anti-detachment block, an anti-detachment spring, and a gripping rod. The anti-detachment block is slidably connected to the limiting rod along a length direction perpendicular to the limiting rod. The moving block has a snap-fit ​​groove, and the anti-detachment spring is used for the anti-detachment block to snap into the snap-fit ​​groove. The length direction of the gripping rod is parallel to the sliding direction of the anti-detachment block, and one end of the gripping rod is disposed on the anti-detachment block.

[0011] By adopting the above technical solution, the anti-detachment component is pushed by the anti-detachment spring to engage the anti-detachment block into the engagement groove of the moving block. This further reinforces the fixed state of the moving block on the basis of the limiting rod, preventing the moving block from shifting due to vibration and other factors during equipment operation, thus improving structural stability. At the same time, the gripping rod allows workers to manually pull the anti-detachment block out of the engagement groove without affecting the rotation of the moving block. This balances the reliability of the fixation with the convenience of operation, ensuring the safety of the processing process and the smoothness of parts replacement.

[0012] Optionally, the moving block is provided with a rotating handle.

[0013] By adopting the above technical solution, the rotating handle provides a convenient point of force for the operator to rotate the moving block. The operator can easily control the rotation of the moving block without the need for additional tools, which reduces the difficulty of rotating the moving block, further improves the ease of operation when replacing clamping parts, saves operation time, and indirectly improves work efficiency.

[0014] Optionally, both the moving block and the fixed block are provided with arc-shaped grooves for installing clamping accessories. The bottom of the arc-shaped groove is provided with a guide groove. The clamping accessory is arched. The outer side wall of the clamping accessory abuts against the arc-shaped groove. A guide rod is provided on the outer side wall of the clamping accessory. The guide rod is used to pass into the guide groove. The clamping accessory is flush with the outer surface of the corresponding block.

[0015] By adopting the above technical solution, the arc-shaped groove is adapted to the outer wall of the arched clamping accessory, and the guide rod is inserted into the guide groove, which can play a positioning and guiding role in the installation of the clamping accessory, ensuring that the clamping accessory is quickly and accurately installed on the moving block or fixed block, reducing the installation and adjustment time; at the same time, the clamping accessory is flush with the outer surface of the corresponding block, avoiding protrusions or depressions after installation, ensuring the fit between the moving block and the fixed block, ensuring that the hole and groove shape formed by the two clamping accessories is regular, and improving the stability and processing accuracy of pipe clamping.

[0016] Optionally, the moving block is provided with a buffer rubber layer to reduce the impact force with the moving block.

[0017] By adopting the above technical solution, the buffer rubber layer can effectively reduce the impact force when the moving block rotates to the working position or comes into contact with the moving block, reduce vibration and noise during equipment operation, reduce wear on the moving block and the moving block, extend the service life of the components, and at the same time avoid component displacement caused by impact, ensure the accuracy and stability of the equipment for long-term use, and improve the smoothness of equipment operation.

[0018] Optionally, the frame is further provided with a jacking pipe assembly, which is located on the side of the clamping assembly away from the forming assembly. The jacking pipe assembly includes a top block, a movable seat, and a locking bolt. The movable seat is slidably connected to the frame along the axial direction of the pipe. The top block is disposed on the movable seat and is used to abut against the end of the pipe. The tail of the locking bolt is threadedly connected to the movable seat and abuts against the frame.

[0019] By adopting the above technical solution, the movable seat of the jacking assembly can slide along the axis of the pipe fitting, and the top block can abut against the end of the pipe fitting. The position of the movable seat is fixed by locking bolts. The support position of the top block can be adjusted according to the length of the pipe fitting, which plays an axial positioning and support role for the pipe fitting, preventing axial movement of the pipe fitting during the pipe shrinking process and ensuring the dimensional accuracy of the pipe shrinking. At the same time, it adapts to the processing requirements of pipe fittings of different lengths, improves the versatility of the equipment, eliminates the need for additional positioning mechanisms, and simplifies the processing process.

[0020] Optionally, the molding assembly includes a molding cylinder, a mounting base, a mounting tube, and a molding die. The mounting base is slidably connected to the frame along the axial direction of the pipe. The molding cylinder drives the mounting base to move. The mounting tube is coaxially arranged with the pipe and is mounted on the mounting base. The molding die is installed on the mounting tube by bolts.

[0021] By adopting the above technical solution, the forming mold is installed on the installation pipe by bolts. When it is necessary to adjust the pipe shrinkage size, the bolts can be easily disassembled and replaced with a suitable forming mold. With the replacement of clamping accessories, the equipment can quickly adapt to the processing needs of different pipe sizes or different shrinkage requirements, further improving the versatility and ease of operation of the equipment, reducing equipment adjustment time, and improving the flexibility and efficiency of production and processing.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The moving block can rotate horizontally to move the clamping parts to the upper side for easy operation. With the rotating handle, a single person can quickly disassemble and assemble without having to look up. The molding die bolts are easy to replace, solving the problem of cumbersome replacement in the past and shortening the equipment adjustment time. 2. The double-fixed moving block with limiting and anti-detachment components prevents displacement; the clamping accessories are precisely positioned by arc grooves and guide rods, and the holes and grooves are regular; the jacking pipe assembly locks the pipe to prevent movement, and the multiple structures reduce processing errors and ensure the accuracy of pipe shrinking; 3. Interchangeable clamping accessories, forming molds, and adjustable jacking pipe components to adapt to different pipe fittings and pipe shrinking requirements; the buffer rubber layer reduces impact, vibration and wear, improves equipment adaptability and durability, and reduces maintenance costs.

The constricted end of the forming mold 34 faces the tube.

[0037] The implementation principle of a pipe end forming machine with convenient replacement parts in this application embodiment is as follows: During implementation, the pipe length and pipe shrinkage requirements are adjusted first: the moving seat 42 of the sliding jacking pipe assembly 4 makes the jacking block 41 adapt to the pipe length, the locking bolt 43 is tightened to fix it, and then a suitable forming mold 34 is selected and fixed on the installation pipe 33 with bolts. At the same time, the moving block 23 is fixed in the working state by the limiting member 26.

[0038] During processing, the drive cylinder 21 drives the moving block 25 and the moving block 23 to move down, so that the clamping accessories 24 on the fixed block 22 and the moving block 23 are positioned by the arc groove 221 and the guide rod 241 to form a hole and groove to clamp the pipe. The limiting rod 262 is inserted into the limiting plates 231 on both sides of the moving block 23, and the anti-detachment spring 272 pushes the anti-detachment block 271 to engage with the moving block 23 and the engaging groove 232, so as to achieve stable fixing of the pipe. Then, the forming cylinder 31 pushes the mounting base 32, the mounting tube 33 and the forming mold 34 to move towards the end of the pipe. The mold is used to squeeze the pipe to complete the shrinkage. The top block 41 abuts against the other end of the pipe to prevent movement.

[0039] When it is necessary to replace the parts, pull the grip 273 to disengage the anti-detachment block 271 from the snap-fit ​​groove 232, remove the limiting rod 262, and rotate the handle 234 to move the moving block 23 above the moving block 25. The buffer rubber layer 233 reduces the impact and wear of the parts, and the bolts can be easily removed to replace the clamping parts 24. The forming mold 34 can be directly replaced by removing the bolts. After the parts are replaced, the moving block 23 is reset and limited by the limiting part 26 and the anti-detachment part 27, and then it can enter the processing of new specification pipe fittings.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
