Technical Field

[0001] The utility model relates to the technical field of PE pipe fitting processing and expanding machines, in particular to a PE pipe fitting processing and expanding machine. Background Art

[0002] PE is polyethylene plastic, the most basic type of plastic. Plastic bags, cling film, etc. are all PE. PE has excellent resistance to most daily and industrial chemicals. PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes, which are widely used in modern industry or life. When using PE pipes, one end of the PE pipe needs to be expanded for easy connection.

[0003] The existing expansion methods are mostly to heat the PE pipe head through a heating hood, and then insert an extruded tube into the pipe head to expand the pipe. However, the existing heating hoods and extruded tubes are mostly fixed structures. When the size of the pipe changes, different heating hoods and extruded tubes need to be replaced. The applicability is poor, and the replacement is cumbersome, which affects the work efficiency. Therefore, we propose a PE pipe processing and expanding machine to solve the above problems.

[0024] The first threaded rod 4 is a double-threaded structure, so that the first clamping block 5 can move the object, thereby completing the clamping work, and the first clamping block 5 is connected to the second clamping blocks 6 on both sides through a connecting rod, so that the second clamping block 6 can move with the movement of the first clamping block 5, and the surfaces of the first clamping block 5 and the second clamping block 6 are arc-shaped, which is convenient for clamping, and the first threaded rod 4 is crookedly connected to a motor.

[0025] The extrusion plate 10 forms a clamping and fixing structure with the first clamping block 5 and the second clamping block 6 on the clamping base 2 through the hydraulic cylinder 9. The extrusion plate 10 is driven downward by the hydraulic cylinder 9 to squeeze and fix the pipeline twice.

[0026] The first movable platform 11 is threadedly connected to the second threaded rod 12 through a connecting block, so that the flaring rod 19 is inserted into the pipe after heating is completed. A motor is connected to the outside of the second threaded rod 12, and the threaded connecting block of the heating base 14 and the third threaded rod 13 form a threaded movable structure on the first movable platform 11, so that the flaring rod 19 can be on the same horizontal line as the center of the pipe to be flared.

[0029] Working principle: When using the PE pipe processing and expanding machine, first, put the PE pipe to be processed on the clamping base 2, and then start the motor outside the first threaded rod 4 in the clamping base 2, so that the first threaded rod 4 drives the first clamping block 5 to move on the first threaded rod 4 through the threaded connecting block, and at the same time, the second clamping blocks 6 connected to the connecting rods on both sides also move with the movement of the first clamping block 5, so as to clamp the two sides of the pipe fitting, and at the same time start the hydraulic cylinder 9 on the top connecting frame 8, so that the extrusion plate 10 under the hydraulic cylinder 9 is squeezed downward, so as to complete the fixing of the pipe fitting, and then rotate the fifth threaded rod 21 on the right side of the clamping base 2, so that the limit plate 20 connected to the fifth threaded rod 21 moves to the left and presses against the right end of the pipe fitting;

[0030] Then start the motor on the third threaded rod 13 on the first movable platform 11, so that the center of the flaring rod 19 in the connecting base 18 on the heating base 14 is aligned with the center of the pipe fitting, and then start the motor on the outside of the second threaded rod 12 under the first movable platform 11, so that the first movable platform 11 is moved to the right through the rotation of the second threaded rod 12, and at the same time start the heating function of the heating rod 17, and then know that the front end of the heating cover composed of the heating rod 17 wraps the position of the end of the pipe, and turn off the motor on the outside of the second threaded rod 12. Then, the motor connected to the rear side of the first transmission rod 15 in the heating base 14 is started, so that the first transmission rod 15 drives the fourth threaded rod 16 to rotate through the bevel gear, so that the heating rod 17 moves following the rotation of the fourth threaded rod 16, so that the heating cover formed by the heating rod 17 is reduced until it is close to the size of the end of the pipe, and then the motor on the outside of the second threaded rod 12 under the first movable platform 11 is started again to rotate slowly, so that the heating cover formed by the heating rod 17 heats the pipe while the internal flaring rod 19 slowly extends into the pipe to perform flaring work. When the flaring distance is reached, the heating rod 17 is turned off, and the motor on the outside of the second threaded rod 12 under the first movable platform 11 is started to rotate in the opposite direction, and the flaring rod 19 is pulled out, and the flaring work is completed.
