[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0028] Please refer to Figures 1 to 6 The present invention provides a shaping head for shaping a pipe fitting, the shaping head comprising: an inner punch 1, the inner punch 1 being provided with a guide surface 11, the inner punch 1 being able to be inserted into the inner hole of the pipe fitting under the guidance of the guide surface 11 to shape the inner wall of the pipe fitting; an outer punch 2 being arranged around at least a portion of the inner punch 1, a shaping groove 100 for inserting the pipe fitting being formed between the inner punch 1 and the outer punch 2; wherein a cutting portion 21 is provided on a side of the inner punch 1 close to the shaping groove 100; when relative rotation occurs between the shaping head and the pipe fitting, the cutting portion 21 cuts off burrs on the outer wall of the pipe fitting to shape the outer wall of the pipe fitting.
[0029] The shaping head of the present invention is used to shape pipe fittings, and the shaping head includes: an inner punch 1, which is provided with a guide surface 11. The inner punch 1 can be inserted into the inner hole of the pipe fitting under the guidance of the guide surface 11 to shape the inner wall of the pipe fitting; an outer punch 2, which is arranged around at least a portion of the inner punch 1, and a shaping groove 100 for inserting the pipe fitting is formed between the inner punch 1 and the outer punch 2; wherein, a cutting portion 21 is provided on the side of the inner punch 1 close to the shaping groove 100; when relative rotation occurs between the shaping head and the pipe fitting, the cutting portion 21 cuts burrs on the outer wall of the pipe fitting to shape the outer wall of the pipe fitting. In this way, when shaping the pipe fitting, the pipe fitting is inserted into the shaping groove 100, and then the shaping head is rotated relative to the pipe fitting. The inner punch 1 will remove the burrs on the inner wall of the pipe fitting port and trim the inner hole of the pipe fitting into a circle. The outer punch 2 can remove the burrs on the outer wall of the pipe fitting, thereby realizing the shaping of the inner and outer walls of the pipe fitting at one time, which greatly facilitates the shaping operation of the pipe fitting and solves the problem of low shaping efficiency of the pipe fitting port in the prior art.
[0030] The shaping head includes a mounting base 3 having a mounting hole 31 formed therein, into which both the inner punch 1 and the outer punch 2 are detachably mounted. The mounting base 3 also includes a connecting portion 32 for connecting to a drive device to rotate the shaping head. This effectively facilitates the processing and maintenance of the shaping head.
[0031] The mounting hole 31 includes a first hole section 311 for inserting the inner punch 1 and a second hole section 312 for inserting the outer punch 2; a first locking hole 34 and a second locking hole 35 are provided on the mounting base 3, and the first locking hole 34 extends to the first hole section 311 so as to tighten and fix the inner punch 1 through a first fastener installed in the first locking hole 34; the second locking hole 35 extends to the second hole section 312 so as to tighten and fix the outer punch 2 through a second fastener installed in the second locking hole 35.

Specifically, the first locking hole 34 and the second locking hole 35 are both threaded holes, and the first fastener and the second fastener are provided with external threads. By rotating the first fastener or the second fastener, the first fastener or the second fastener can be tightened on the corresponding inner punch 1 or outer punch 2.
[0032] In order to discharge the waste chips generated by shaping to the outside of the shaping groove 100 in time to avoid affecting the subsequent shaping operation, a chip discharge port 33 is provided on the mounting seat 3. When the inner punch 1 and the outer punch 2 are installed in the mounting hole 31, the chip discharge port 33 is connected to the shaping groove 100 so that the burrs cut off by the cutting part 21 can be discharged through the chip discharge port 33.
[0033] Specifically, at least a portion of the inner punch 1 is a cylindrical structure, the diameter of which matches the diameter of the inner hole of the pipe.

The contact surface 22 is at least a portion of a cylindrical surface, the diameter of which matches the outer diameter of the pipe. The cutting portion 21 is a groove provided on the contact surface 22. In this way, the inner punch 1 can be used to align the inner hole of the pipe and remove internal burrs, while the cutting portion 21 of the outer punch 2 can be used to cut the outer wall of the pipe and remove external burrs, thereby ensuring that the end of the pipe after shaping is burr-free and has higher dimensional accuracy.
[0034] Please refer to Figures 7 and 8 The present invention also provides a shaping device, which includes a driving device 10 and a shaping head 20 for shaping the pipe. The driving device 10 is connected to the shaping head 20 to drive the shaping head 20 to rotate. The shaping head 20 is the above-mentioned shaping head.
[0035] Specifically, the driving device 10 includes: a motor 101; a transmission assembly 102, the transmission assembly 102 includes a bracket and a transmission shaft, the transmission shaft is rotatably mounted on the bracket, and the shaping head 20 is mounted on the transmission shaft; the transmission shaft is connected to the output shaft of the motor 101 to drive the transmission shaft to rotate through the motor 101.
[0036] Preferably, motor 101 is a servo motor, specifically a three-phase asynchronous motor, connected to a frequency converter for operation via the frequency converter controller. This allows for flexible control of the motor 101's rotational speed, enabling uniform startup, high-speed rotation (shaping), and low-speed idling, ensuring smooth startup, shaping effectiveness, and longevity. In this embodiment, the drive shaft is mounted on the bracket via back-to-back thrust angular contact ball bearings, enabling the bracket to exert reliable axial support on the drive shaft, ensuring a shaping effect on the pipe.

The transmission shafts of the multiple transmission assemblies 102 are each equipped with a second pulley 1021; the driving device 10 also includes a transmission belt 103, which cooperates with the first pulley 1011 and the multiple second pulleys 1021. In this way, the motor 101 can simultaneously drive the transmission shafts of multiple transmission assemblies 102 to rotate, thereby driving the rotation of multiple shaping heads 20, achieving the purpose of shaping multiple pipes at the same time, and improving the shaping efficiency of the shaping equipment.
[0038] To facilitate pipe shaping, the shaping head 20 is rotatably mounted about a predetermined axis. The shaping apparatus includes a slide 30, which is movably mounted along the predetermined axis. The drive unit 10 and the shaping head 20 are both mounted on the slide 30. Once the pipe is in place, the end of the pipe can be conveniently inserted into or removed from the shaping groove 100 by controlling the sliding motion of the slide 30.

[0040] The sliding guide structure 40 includes a slide rail and a slider. The slide rail extends along the direction of the predetermined axis. The slider is slidably mounted on the slide rail and is connected to the slide 30. The sliding drive structure 50 includes a screw-nut mechanism and a rotary drive mechanism. The rotary drive mechanism is connected to the screw-nut mechanism via a belt drive structure to drive the screw-nut mechanism through the rotary drive mechanism. The screw-nut mechanism includes a rotatable screw and a nut slider that cooperates with the screw. The nut slider is connected to the slide 30. When the rotary drive mechanism drives the screw to rotate, the nut slider drives the slide 30 to move.
[0041] The shaping apparatus also includes an oil spray mechanism 70, which has an oil spray hole positioned toward the shaping head 20. This spray hole sprays oil toward the contact point between the shaping head 20 and the pipe as the shaping head 20 shapes the pipe. The oil spray mechanism 70 sprays oil toward the shaping area, providing lubrication and minimizing damage to the pipe.
[0042] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
[0043] The shaping head of the present invention is used to shape pipe fittings, and the shaping head includes: an inner punch 1, which is provided with a guide surface 11. The inner punch 1 can be inserted into the inner hole of the pipe fitting under the guidance of the guide surface 11 to shape the inner wall of the pipe fitting; an outer punch 2, which is arranged around at least a portion of the inner punch 1, and a shaping groove 100 for inserting the pipe fitting is formed between the inner punch 1 and the outer punch 2; wherein, a cutting portion 21 is provided on the side of the inner punch 1 close to the shaping groove 100; when relative rotation occurs between the shaping head and the pipe fitting, the cutting portion 21 cuts burrs on the outer wall of the pipe fitting to shape the outer wall of the pipe fitting. In this way, when shaping the pipe fitting, the pipe fitting is inserted into the shaping groove 100, and then the shaping head is rotated relative to the pipe fitting. The inner punch 1 will remove the burrs on the inner wall of the pipe fitting port and trim the inner hole of the pipe fitting into a circle. The outer punch 2 can remove the burrs on the outer wall of the pipe fitting, thereby realizing the shaping of the inner and outer walls of the pipe fitting at one time, which greatly facilitates the shaping operation of the pipe fitting and solves the problem of low shaping efficiency of the pipe fitting port in the prior art.
