And the foremost end of the base 3 is provided with a positioning mechanism, and the positioning mechanism is used for determining the length of the flanging needed by the tetrafluoride pipe and supporting the flanging at the later stage conveniently.
Specifically, the centering mechanism 5 comprises a first leg 7, the first leg 7 is slidably disposed on the slide rail 4, and when the centering mechanism slides to a specific position, the centering mechanism can be locked on the slide rail 4 through a bolt in a through hole at the bottom end of the first leg 7. A cross beam 8 is arranged at the top end of the first support leg 7, a threaded sleeve 9 is fixedly connected to the periphery of the cross beam 8, and a screw rod 10 is connected to the threaded sleeve 9 in a threaded mode; when the screw 10 is rotated outwards, the rod formed by the threaded sleeve 9 and the screw 10 is extended as a whole, and is shortened otherwise. The end of each screw rod 10 is provided with a spherical head, and the spherical head can be tightly pressed against the inner wall of the polytetrafluoroethylene tube after the support rod is extended to a proper length. In order to realize centering, namely to ensure the length of each strut to be consistent, different color indicating lines can be sprayed on the screw 10 along the length direction, and the indicating lines with different colors represent the inner diameters of different tetrafluoride pipes.
The jacking mechanism 6 comprises a second supporting leg 11, an adjusting ring 12 is arranged on the second supporting leg 11, and the diameter of the adjusting ring 12 is larger than or equal to that of the largest specification size of the tetrafluoro pipe. A plurality of screw rods 13 are circumferentially arranged on the adjusting ring 12, and arc-shaped plates 14 are arranged at the ends of the screw rods 13. When the pipe needs to be tightly pressed, the tetrafluoride pipe passes through the adjusting ring 12, then is screwed into the screw rod 13, and is tightly pressed on the outer wall of the tetrafluoride pipe by utilizing the arc-shaped plate 14. Since the centering mechanism 5 has completed centering in advance, the lead screw is screwed into the adjusting ring 12 to a uniform length.
The positioning mechanism comprises vertical sliding rails 15 arranged on the left side and the right side of the base 3, U-shaped grooves are formed in opposite surfaces of the two vertical sliding rails 15 in the vertical direction, sliding grooves 18 are formed in end surfaces, close to one side of the jacking mechanism 6, of the two vertical sliding rails 15 in the vertical direction, and the sliding grooves 18 are communicated with the U-shaped grooves. The left side and the right side of the positioning disk 16 are arranged in the U-shaped groove in a sliding mode through the sliding blocks, and the threaded heads 17 on the side faces of the sliding blocks can extend out of the sliding grooves 18 and then can be locked through nuts, so that the positioning disk 16 can be kept fixed.
The positioning plate 16 here includes a positioning ring at the front end and a semicircular ring at the rear end, the inner diameters of the positioning ring and the semicircular ring are the same as the outer diameter of the tetrafluoro-tube, and the length from the inner edge to the outer edge of the positioning ring is slightly longer than the length of the flange. The positioning disc 16 with corresponding size can be customized according to the tetrafluoride pipes with different specifications, and the sleeve joint can be realized only by ensuring that the corresponding inner hole is matched with the tetrafluoride pipe.
The top end of the positioning plate 16 is correspondingly hinged with a fixed length rod 26, and the fixed length rods 26 on different positioning plates 16 correspond to the required flanging length of the tetrafluoride pipe matched with the positioning plate 16, so that the flanging extension can be directly determined.
In addition, the front end of the beam 8 is provided with a stepped shaft 27, and the diameter of the stepped shaft 27 is gradually reduced from one end to the other end. The structure can be used for the tetrafluoride pipe with smaller specification and size, and different sections of the stepped shaft 27 can be sleeved with the tetrafluoride pipe, so that the self-centering is realized, and the clamping of the jacking mechanism 6 is facilitated.
Specifically, turn-ups positioner 2 includes mount pad 19, and the 19 front end left and right sides of mount pad is equipped with toper heating turn-ups mechanism 20, stock mould 21 respectively, and wherein, toper heating turn-ups mechanism 20, stock mould 21 refer to "a quick turn-ups device of tetrafluoro tube" the patent that application number is "201721361901.9". The rear end of the mounting seat 19 is connected with a motor 22, and the motor 22 is slidably arranged on a sliding seat 24 through a bracket 23 and is pushed by an air cylinder 25 to move back and forth. The sequential actions of the motor and the air cylinder are regulated and controlled by the singlechip. Meanwhile, the temperature of the conical heating flanging mechanism 20 is controlled by the single chip microcomputer.
The cross section of the beam 8 is square, the center of the square, the axis of the stepped shaft 27, the axis of the adjusting ring 12, the axis of the conical heating flanging mechanism 20 after rotation and the axis of the shaping mold 21 after rotation are overlapped at the corresponding projection surface, so that the axes of the tetrafluoride tube after installation of any specification and the axes of the conical heating flanging mechanism 20 and the shaping mold 21 are positioned on the same straight line, and the requirement of molding is met.
The working principle and the process are as follows: when the tetrafluoro pipe of a certain specification needs to be flanged, the tetrafluoro pipe firstly passes through the adjusting ring 12, the screws 10 of the two centering mechanisms 5 and the like extend into the tetrafluoro pipe from two ends of the tetrafluoro pipe, then each screw 10 is adjusted, the four screws 10 extend to the same length and are tightly propped against the tetrafluoro pipe, so that the center of the cross beam and the center of the tetrafluoro pipe are approximately at the same point, and the tetrafluoro pipe can be kept horizontal through the adjustment of the two centering mechanisms 5. And then the screw rod 13 is locked, so that the two jacking mechanisms 6 and the tetrafluoride pipe form a whole. And (3) moving the centering mechanism 5 close to one side of the positioning mechanism, moving the whole body formed by the two jacking mechanisms 6 and the tetrafluoride pipe forwards, enabling the tetrafluoride pipe to extend out of the positioning disc 16 by a certain length, rotating the fixed length rod 26, enabling the fixed length rod 26 to horizontally point to one end of the tetrafluoride pipe extending out and align with the end face of the tetrafluoride pipe extending out, and enabling the length of the tetrafluoride pipe extending out to be the required flanging length. And then fixing bolts at the lower ends of the second support legs 11 of the two tightening mechanisms 6, so that the two tightening mechanisms 6 and the tetrafluoride pipe are kept fixed.
Then the controller controls the corresponding cylinder 25 to extend, so that the conical heating flanging mechanism 20 in a constant temperature state extends into the tetrafluoro pipe for hot melting, the cylinder 25 retracts after a certain time, then the motor drives the mounting seat 19 to rotate 180 degrees, so that the stock mold 21 is right opposite to the tetrafluoro pipe, the cylinder 25 extends out again, the thinner section of the stock mold 21 extends into the tetrafluoro pipe, and the large disc at the rear end of the stock mold 21 flattens the surface of the conical pipe subjected to hot melting to form a flanging.
