[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] A pusher for processing tubular workpieces includes a base 1, a first fixed seat 2 fixed on one side of the base 1, a second fixed seat 3 on the other side of the base 1, and a pusher plate 5 is movably installed between the first fixed seat 2 and the second fixed seat 3 along the length direction. The tubular workpiece can be moved by the pusher plate 5.

[0023] A drive structure 4 is installed between the first fixed seat 2 and the second fixed seat 3. Specifically, the drive structure 4 includes a first motor 401 installed on the outside of the first fixed seat 2, and the output shaft of the first motor 401 passes through the first fixed seat 2 and is fixed with a first lead screw 402. The other end of the first lead screw 402 is rotatably connected to the inner wall of the second fixed seat 3. A threaded hole 502 is provided at the lower part of the push plate 5. The push plate 5 is threaded onto the first lead screw 402 through the threaded hole 502. When the first motor 401 drives the first lead screw 402 to rotate, the first lead screw 402 can drive the push plate 5 to move. The push plate 5 can continuously push the tubular workpiece to move. Normally, an installation hole 501 is provided at the center of the upper part of the push plate 5. During the installation of the tubular workpiece, one end of the tubular workpiece can extend into the interior of the installation hole 501.

[0024] A plurality of first guide rods 13 are fixed between the first fixed seat 2 and the second fixed seat 3, and the push plate 5 is provided with guide holes that are slidably installed on the first guide rods 13. Through the cooperation of the first guide rods 13 and the guide holes, the push plate 5 is limited to prevent it from shaking during use.

[0025] A guide rail 14 is fixed on the top of the base 1 along the length direction; a guide groove 15 is provided below the push plate 5, and the push plate 5 is slidably mounted on the guide rail 14 through the guide groove 15. The cooperation between the guide rail 14 and the guide groove 15 further limits the push plate 5, so that the push plate 5 has good stability.

[0026] A bidirectional cylinder 16 is installed below one side of the push plate 5, and clamping arms 17 are respectively installed on the two drive ends of the bidirectional cylinder 16. The top of the two clamping arms 17 is respectively fixed with an arc-shaped clamping plate 18. When one end of the tubular workpiece passes through the mounting hole 501, the two output ends of the bidirectional cylinder 16 can retract and drive the clamping arms 17 to move in opposite directions. The tubular workpiece can be clamped by the arc-shaped clamping plates 18 above the two clamping arms 17, preventing the tubular workpiece from shaking during the push process, thereby improving the stability of the device.

[0027] It should be noted that there are two second fixed seats 3, and several mounting supports 6 are fixed between the two second fixed seats 3. The multiple mounting supports 6 are connected to the same lifting plate 8 through the same lifting structure 7. Through the setting of the lifting structure 7, the height of the lifting plate 8 can be adjusted.

[0028] In detail: The lifting structure 7 includes a second motor 701 installed on the side of one of the mounting supports 6, and worm gear screw jacks 702 (worm gear screw jacks are existing technology and will not be described in detail here) are respectively installed on the top of multiple mounting supports 6. There are usually two worm gear screw jacks 702. The top of the worm gear screw jacks 702 is connected to the bottom of the moving plate 10. By setting up several worm gear screw jacks 702, the lifting plate 8 can be driven to adjust up and down. The two ends of the drive rod 703 are respectively installed on the drive end of the worm gear screw jacks 702. By setting up the drive rod 703, the two worm gear screw jacks 702 can work synchronously. The output shaft of the second motor 701 is fixedly connected to the input end of one of the worm gear screw jacks 702, thereby playing a driving role.

[0029] A movable structure 9 is installed between the lifting plate 8 and the movable plate 10. The movable structure 9 can drive the movable plate 10 to make horizontal adjustments.

[0030] In detail: The moving structure 9 includes rotating supports 901 symmetrically fixed at both ends of the lifting plate 8. A second lead screw 902 is rotatably installed between the two rotating supports 901, and one end of the lead screw 902 is fixedly connected to a third motor 904 fixed on the rotating support 901. A threaded drive seat 903 is threadedly installed on the second lead screw 902, and the top of the threaded drive seat 903 is fixed to the bottom of the moving plate 10. When the third motor 904 drives the second lead screw 902 to rotate, the second lead screw 902 can drive the moving plate 10 to make fine adjustments left and right through the threaded drive seat 903, so as to adjust according to the situation of the tubular workpiece and have strong flexibility.

[0031] Several second guide rods 19 are fixed to the top of the lifting plate 8, and the second guide rods 19 are arranged parallel to the second lead screw 902. A guide seat 20 is slidably installed on the second guide rod 19, and the guide seat 20 is fixed to the bottom of the moving plate 10. Through the cooperation of the second guide rod 19 and the guide seat 20, the moving plate 10 is limited to prevent it from shaking or loosening during use.

[0032] A medium-frequency transformer 11 is installed on the top of the movable plate 10, and a heating tube 12 is installed on the side of the medium-frequency transformer 11. The heating tube 12 can be used to heat the tubular workpiece. The heating tube 12 is electrically connected to the medium-frequency transformer 11. It should be noted that the medium-frequency transformer 11 and the heating tube 12 are both known prior art, and will not be described in detail in this application.

[0033] When processing a tubular workpiece: First, insert one end of the tubular workpiece into the mounting hole 501. Then, activate the bidirectional cylinder 16. The two output ends of the bidirectional cylinder 16 drive the clamping arms 17 to move in opposite directions, so that the two clamping arms 17 drive the "arc"-shaped clamping plates 18 to move. The two "arc"-shaped clamping plates 18 can clamp one end of the tubular workpiece. Then, simultaneously activate the first motor 401 and the heating tube 12. When the first motor 401 drives the first lead screw 402 to rotate, the first lead screw 402 can drive the tubular workpiece to move through the push plate 5. Then, the heating tube 12 heats different positions of the tubular workpiece.

[0034] When heating a bent tubular workpiece, the heating tube 12 can be adjusted up and down or left and right according to the degree of bending of the tubular workpiece.

[0035] When adjusting the heating tube 12 up and down: First, the second motor 701 can drive the worm gear screw jack 702 to lift. Since the two worm gear screw jacks 702 are connected to each other, they can drive the lifting plate 8 to lift. The lifting plate 8 can drive the intermediate frequency transformer 11 to lift through the moving plate 10, so that the moving plate 11 can lift the heating tube 12. Thus, the height of the heating tube 12 can be adjusted according to the degree of bending of the tubular workpiece.

[0036] When adjusting the heating tube 12 left and right: First, turn on the third motor 904. The output shaft of the third motor 904 can drive the second lead screw 902 to rotate. The second lead screw 902 can drive the moving plate 10 to move through the threaded drive seat 903. The moving plate 10 drives the heating tube 12 to move left and right through the intermediate frequency transformer 11, so that it can be adjusted left and right according to the degree of bending of the tubular workpiece, which has strong flexibility.
