Description

Technical Field

[0001] This utility model relates to the technical field of pipe shrinking machines, and in particular to a pipe feeding mechanism for a CNC shrinking machine. Background Technology

[0002] When pipe fittings are being processed to reduce their diameter, they are all supplied manually by workers. After each pipe fitting is processed, the worker needs to remove the processed pipe fitting and then put in the unprocessed pipe fitting. This method of supplying materials is inefficient and not conducive to large-scale production. At the same time, it requires workers to keep a close eye on the process, resulting in high labor costs. One worker can only be responsible for one machine. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tube feeding mechanism for a CNC tube shrinking machine, so as to solve the problems of low efficiency and high labor cost of manual feeding in the background art.

The bottom of each first clamping groove on the rotating column has a moving groove.

[0011] Several baffles, one end of which slides into several movable slots and is connected to the inner wall of the movable slots by springs;

[0012] The second movable plate is movably mounted on the processing table;

[0013] Several clamping plates are arranged vertically on the second movable plate, and each clamping plate has a second clamping groove corresponding to the position of the first clamping groove;

[0014] A push plate is movably mounted on the processing table, facing the baffle to push the baffle into the moving groove. The processing table has a discharge hole located below the first clamping groove facing the push plate.

[0015] Preferably, the outer wall of the box is provided with a second cylinder, the output end of which is connected to the first movable plate, and the rubber column is disposed on the first movable plate.

[0016] Preferably, the end wall of the box is provided with a first cylinder, and the output end of the first cylinder is fixedly connected to the top plate.

By moving the top plate and rubber column, the pipe fittings can be moved one by one to the position of the discharge hole and pass through the discharge hole, so that the pipe fittings fall into the first clamping groove and are supported by the baffle and blocked by the limiting plate. Then, they follow the rotation of the rotating column, so that the rotating column rotates to the position of the clamping plate. Then the clamping plate moves, so that the second clamping groove and the first clamping groove clamp the pipe fittings. At this time, the external shrinking machine can shrink the upper end of the pipe fittings. After the processing is completed, the rotating column sends the shrinking pipe fittings to the bottom of the discharge hole. Then the push plate pushes the baffle to fully enter the moving groove. At this time, the pipe fittings will pass through the discharge hole and the unloading is completed. This application can reduce labor costs, and one worker can supervise multiple machines at the same time. Attached Figure Description

[0031] The box body 30 passes through the first support plate 20 and is fixedly connected to the first support plate 20. The bottom of the box body 30 near the end wall has a material discharge hole 31.

[0032] The top plate 32 is disposed on one side end wall of the box body 30. The end wall of the box body 30 is provided with a first cylinder 33, and the output end of the first cylinder 33 is fixedly connected to the top plate 32.

[0033] A rubber column 40 slides through the other end wall of the box body 30. The rubber column 40 is located above the material discharge hole 31. A second cylinder 42 is provided on the outer wall of the box body 30. The output end of the second cylinder 42 is connected to the first moving plate 41. The rubber column 40 is provided on the first moving plate 41.

[0034] A rotating column 50 is rotatably mounted on a processing table 10. Several first clamping grooves 51 are evenly arranged on the outer wall of the rotating column 50, one of which is directly opposite the material dropping hole 31. Several limiting plates 52 are respectively arranged on the outer wall of the rotating column 50 corresponding to the position of each first clamping groove 51. The bottom of each first clamping groove 51 on the rotating column 50 has a moving groove 54. A reducer is provided on the processing table 10. The output end of the reducer is connected to the rotating shaft of the rotating column 50. The reducer has a servo motor 56 for driving the reducer.

[0035] Several baffles 53 have one end that slides into several movable grooves 54 and is connected to the inner wall of the movable grooves 54 by springs 55.

[0036] The second movable plate 62 is movably mounted on the processing table 10. The processing table 10 is provided with a second support plate 64. The second support plate 64 has a third cylinder 63. The output end of the third cylinder 63 is connected to the second movable plate 62.

[0037] Several clamping plates 60 are arranged vertically on the second movable plate 62, and each clamping plate 60 has a second clamping groove 61 corresponding to the position of the first clamping groove 51.

[0038] A push plate 70 is movably mounted on the processing table 10. The push plate 70 is directly opposite the baffle 53 so as to push the baffle 53 into the moving groove 54. The processing table 10 has a discharge hole 80, which is located below the first clamping groove 51 directly opposite the push plate 70. A third support plate 72 is provided on the processing table 10, and a fourth cylinder 71 is provided on the third support plate 72. The output end of the fourth cylinder 71 is connected to the push plate 70.

[0039] This embodiment is implemented as follows:

[0040] In use, workers first arrange a large number of pipe fittings in the housing 30, so that the top plate 32 and the rubber column 40 clamp the arranged pipe fittings. When feeding is required, the top plate 32 and the rubber column 40 push the pipe fittings to move, so that the pipe fittings in contact with the rubber column 40 move above the discharge hole 31. Then, the rubber column 40 moves to release the pipe fittings, which causes a pipe fitting to fall downwards under the action of gravity, so that the pipe fitting falls into the first clamping groove 51 and lands on the baffle 53. The limiting plate 52 can prevent the pipe fittings from falling off. Then, the rotating column 50 rotates 90 degrees intermittently. When the pipe fitting rotates to the position of the clamping plate 60, the second moving plate 62 drives the clamping plate 60 to move, so that the second clamping groove 61 of the clamping plate 60 and the first clamping groove 51 of the rotating column 50 clamp the pipe fitting. At this time, the upper end of the pipe fitting can be processed by the external shrinking machine. After processing, the clamping plate 60 returns to its original position, and then the processed pipe fitting moves to the position of the push plate 70. Then, the fourth cylinder 71 drives the push plate 70 to move on the third support plate 72. At this time, the two side walls of the U-shaped push plate 70 will contact the two sides of the baffle 53, so that the push plate 70 completely pushes the baffle 53 into the moving groove 54. The spring 55 is compressed. When the pipe falls, the push plate 70 gradually returns to its original position. Under the action of the spring 55, the baffle 53 also gradually returns to its original position. At this time, the baffle 53 moves relative to the pipe. When the baffle 53 separates from the pipe, the pipe will fall and pass through the discharge hole 80 to complete the unloading.

[0041] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
