Description

Technical Field

[0001] The utility model relates to the field of feeding devices of tube expanders, in particular to a guiding feeding device of tube expanders. Background Art

[0002] The tube expander uses hydraulic drive to expand the end diameter of metal tubes to meet the use requirements of the tubes. During this expansion process, the tubes are transported to the head of the tube expander through hydraulic jacking feeding equipment or pinch roller equipment, and are continuously subjected to the reverse extrusion force of the head of the tube expander, causing the tubes to expand and deform in the axial direction. In order to ensure the quality of the tube expansion process, a guide device is required during the tube feeding process to ensure that the tubes and the head of the tube expander are always on the same axis. This ensures that the wall thickness of the deformed part of the processed tube is uniform and consistent, avoiding cracking and twisting of the tubes.

[0003] The guide feeding devices of current tube expanders are usually customized according to the different specifications of the processed pipe fittings, and are switched for use. When in use, they are fixed to the work surface of the tube expander by bolt anchoring. When processing pipe fittings of different specifications, it is necessary to first remove the original guide device and then reinstall the new guide device. This installation and removal process is relatively cumbersome and time-consuming, which greatly reduces the processing efficiency of the tube expander.

[0004] Therefore, with regard to the guide feeding device used by the above-mentioned tube expander when processing pipe fittings, when faced with the processing of pipes of different specifications, the repeated installation and replacement of different guide devices is cumbersome and consumes manpower and time costs. A tube expander feeding device that can quickly replace the pipe guide mechanism can be designed to shorten the installation and replacement time of the guide mechanism and improve the processing efficiency of the tube expander. Utility Model Content

[0005] In order to overcome the problem that when the tube expander processes tubes of different specifications, it is cumbersome to repeatedly install and replace different guide devices, which consumes a lot of time and labor.

[0006] The technical solution of the utility model is: a guiding feeding device of a tube expander, comprising a cabinet, a tube expander body installed on the left side of the upper end of the cabinet, a material guide table installed on the right end of the cabinet, a positioning mechanism, a dust removal mechanism, a limiting mechanism, a guiding mechanism, and a supporting mechanism; the positioning mechanism is installed on the upper end of the material guide table, a rotatable dust removal mechanism is installed on one side of the positioning mechanism, a T-shaped cross-section slide groove is opened on the upper surface of the material guide table and the limiting mechanism slides axially along the slide groove, the guiding mechanism is between the positioning mechanism and the limiting mechanism, the guiding mechanism is an annular structure with a 30-degree opening at the upper end, and a semi-circular ring-shaped supporting mechanism matched with the guiding mechanism is installed on the limiting mechanism.

[0007] Preferably, the pipe fitting is horizontally inserted into the guide mechanism and is on the same axis as the expander body. The positioning mechanism and the limiting mechanism form opposite clamping and locking on both sides of the guide mechanism to prevent the guide mechanism from shifting during use. The dust removal mechanism uses wind to blow dust off the inner wall of the pipe fitting from one end before the expansion process. The supporting mechanism is used in conjunction with the guiding mechanism to support the pipe body of the pipe fitting.

[0008] Preferably, the positioning mechanism includes a base, a positioning ring, and a positioning rod; the base is installed on the material guide table by bolts, and two sets of arc-shaped positioning rings are fixedly installed on the upper end of the base. The midpoint between the positioning rings is on the same horizontal axis as the head of the tube expander body, and a plurality of positioning rods are installed on the side of the positioning ring facing the guide mechanism. The diameter of the arc-shaped inner wall of the positioning ring is larger than the outer diameter of the pipe to be processed, and it does not play a supporting and guiding role. It mainly serves as a supporting platform for the positioning rod. The base is firmly installed on the material guide table to limit the front and rear displacement and left displacement of the guide mechanism in the horizontal plane.

[0009] Preferably, the dust removal mechanism includes an end platform, a motor, and a blower; the end platform is fixedly connected to one side of the upper end of the base, and a motor is installed on the right side of the end platform. The drive shaft of the motor passes through the end platform and is connected to the blower. When one end of the pipe is in place in the guide mechanism, the motor drives the blower to rotate so that its air outlet is toward the end of the pipe in the guide mechanism, and air is continuously blown into the pipe, and the wind blows away the impurities and dust adhering to the inner wall of the pipe.

[0010] Preferably, the limiting mechanism includes a back plate, a slot, and a socket; the back plate is located on the right side of the guide mechanism, and a slot with an arc-shaped concave shape that is adapted to the supporting mechanism is provided at the upper end of the back plate, and a socket is provided in the middle of the inner wall of the slot. The back plate is supported on the right side of the guide mechanism to limit the horizontal movement of the guide mechanism to the right, and cooperates with the positioning ring to form a clamping and locking effect on the guide mechanism, thereby further improving the stability of the guide mechanism.

[0011] Preferably, the limiting mechanism also includes a handle, a slide, and a No. 1 roller; the handle is fixedly connected to the rear side of the back plate, a slide is installed at the lower end of the back plate and the slide slides in the slide groove on the surface of the guide table, and a No. 1 roller is installed at the lower end of the slide. When installing the guide mechanism, first hold the handle and push the back plate horizontally along the slide groove, using the rolling action of the No. 1 roller in the slide groove until the positioning ring is exposed, then insert the positioning mechanism horizontally to the right side of the positioning mechanism, and then slide the back plate back to its original position.

[0012] Preferably, the guide mechanism includes a guide platform, a guide ring, a positioning hole and a foot support; a guide ring is provided at the upper end of the guide platform, the upper end of the guide ring has an open structure at a 30-degree angle, a plurality of positioning holes are provided on the surface of the guide ring, the positioning rods are horizontally inserted into the corresponding positioning holes, and the left and right ends of the guide platform are fixedly connected with foot supports. After the positioning rods are inserted into the positioning holes, the guide ring is locked on the positioning ring and cannot move forward and backward. The foot supports are respectively supported on the base and the back plate surface on both sides to form a stable horizontal force transmission structure, and the pipe fittings are horizontally penetrated from the guide ring by clamping rollers or hydraulically driven feeding equipment and continuously fed to one side of the tube expander body.

[0013] Preferably, the supporting mechanism includes a supporting ring, a pad, a No. 2 roller, and an insertion rod; a pad is installed at the lower end of the supporting ring, and a No. 2 roller rolling on the surface of the material guide table is installed inside the pad, the left end of the supporting ring is in the slot, and a plug rod inserted into the socket is fixedly connected to the lower side of the left end of the supporting ring. The supporting ring falls into the slot by inserting the plug rod longitudinally into the socket, and is locked with the back plate on a horizontal plane. Through the rolling action of the No. 2 roller on the material guide table, it can move synchronously with the back plate and support the tube body of the tube component.

[0014] Beneficial effects of the utility model:

[0015] 1. The positioning mechanism and the limit mechanism arranged on the guide table can quickly clamp and lock the guide mechanism to prevent the guide mechanism from shifting during use. Compared with the traditional bolt anchoring installation of the guide mechanism, the installation and removal of the guide mechanism in this scheme is simpler and faster, which greatly saves the switching and installation time of the device and improves the processing efficiency of the tube expander in disguised form.

[0016] 2. Before the expansion process, the blower in the dust removal mechanism blows dust from the inner wall of the pipe from one end to prevent hard impurity particles from remaining on the inner wall of the expanded part of the pipe, which may cause scratches on the pipe wall due to extrusion during processing;

[0017] 3. The support ring is used in conjunction with the guide ring to support the pipe body of the pipe fitting, making it convenient for operators to place the pipe fitting on it and slide the pipe fitting accurately into the guide ring, reducing the difficulty of placing the pipe fitting on the guide mechanism.
