[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0025] like Figure 1 , Figure 2 As shown, the utility model provides a copper pipe joint diameter reducing device, comprising a clamping mechanism for clamping a workpiece and driving the workpiece to rotate and a diameter reducing mechanism for reducing the diameter of the workpiece;

[0026] The reducing mechanism includes a reducing forming component I and a reducing forming component II respectively arranged on both sides of the workpiece; the reducing forming component I includes a support column 4, and a forming steel ball 5 is clamped at the front end of the support column 4; the forming steel ball 5 extends out of the support column 4 and can rotate arbitrarily; it also includes a core rod 8 matched with the forming steel ball 5, and the core rod 8 is arranged along the axial direction of the workpiece 100; the spacing between the core rod 8 and the forming steel ball 5 is consistent with the preset thickness of the reduced diameter portion of the workpiece 100; the reducing forming component II includes a cylindrical rotating die 10; the rotating die 10 can rotate along its axis, and its end edges that are used to contact the workpiece are rounded;

[0027] The reducing forming components I and II are fixed on the slider I7 and the slider II9 respectively; the slider I7 and the slider II9 are installed side by side on the base 11 and can reciprocate radially along the workpiece 100, and the base 11 can reciprocate axially along the workpiece 100, so that the reducing forming components I and II reciprocate axially along the workpiece while approaching each other on both sides of the workpiece, thereby reducing the diameter of the workpiece.

[0028] The principle of the utility model is that the forming steel ball 5 and the rotary die 10 gradually move closer to each other after clamping the workpiece from both sides of the workpiece, and at the same time reciprocate along the axial direction of the workpiece, thereby axially stretching and radially pressing the workpiece. The workpiece rotates at high speed during this process, so that the diameter of the workpiece is uniformly reduced in the entire circumference. The core rod 8 is used to support the side wall of the workpiece during processing to prevent the workpiece from sinking under radial pressure. The forming steel ball 5 and the rotary die 10 can both rotate to prevent the workpiece from being scratched during processing.

[0029] In this embodiment, since the front end of the support column 4 supporting the forming steel ball 5 is a cone section, the forming steel ball 5 is installed at the end of the cone section, shaped like the head of a ballpoint pen, to avoid interference between the support column 4 and the workpiece 100.

[0030] In addition, the diameter reduction forming assembly 1 also includes a mounting seat 6, the mounting seat 6 has a connecting hole, the support column 4 is inserted into the connecting hole and locked with a bolt, so that the position of the forming steel ball 5 can be adjusted, so as to be used for processing products of different specifications. Similarly, the position of the core rod 8 and the rotating mold 10 can also be adjusted through the above structure, which will not be repeated here.

[0031] In order to achieve better shrinkage forming, in this embodiment, the angle between the axis of the transfer mold 10 and the axis of the workpiece 100 is 15° to 30°, and the angle between the axis of the support column 4 and the axis of the workpiece 100 is 70° to 85°.

[0032] In order to improve the quality of the workpiece, a cutter 13 is also included for shaping the end of the workpiece after the diameter reduction, and the cutter 13 is installed on the retractable support arm 12. When the diameter reduction mechanism is working, the support arm 12 retracts to avoid interference with the diameter reduction mechanism. After the diameter reduction is completed, the diameter reduction mechanism retreats, and the support arm 12 extends to cut the end of the high-speed rotating workpiece through the cutter 13, thereby improving the quality of the workpiece.

[0033] In order to realize automatic unloading, the clamping mechanism is a chuck 1, and a spring 3 is arranged at the rear of the chuck 1. When the chuck 1 clamps the workpiece 100, the workpiece 100 can compress the spring 3; when the chuck 1 releases the workpiece 100, the spring 3 can eject the workpiece 100. In addition, a pad 2 is arranged at the front end of the spring 3 to increase the contact area between the spring 3 and the workpiece, so as to facilitate the application of thrust to the workpiece to eject it from the chuck.

[0034] In order to realize automatic loading, the present embodiment further includes a loading mechanism; the loading mechanism includes a V-shaped slideway 14 arranged along the axial direction of the workpiece 100; and also includes a push rod 15 for pushing the workpiece in the V-shaped slideway 14 to the clamping mechanism. The V-shaped slideway can adapt to workpieces of different specifications. When the V-shaped slideway 14 is coaxial with the clamping mechanism, the push rod 15 extends to push the workpiece in the V-shaped slideway 14 into the chuck 1 to be clamped by the chuck 1, and at the same time, the spring 3 is compressed to accumulate elastic potential energy for unloading.

[0035] In order to further improve automation, the present embodiment further includes a feeding mechanism, which includes a feeding pipe 16; the feeding pipe 16 uses compressed air to transport the workpiece; a baffle 17 is provided in front of the outlet of the feeding pipe 16; and a push plate 18 is provided at the outlet of the feeding pipe 16 for pushing the workpiece into the V-shaped slide 14. After entering the feeding pipe 16, the workpieces arranged axially by the vibrating feeding plate are transported to the outlet of the feeding pipe 16 by compressed air and are stopped by the baffle 17 in front of the outlet. The push plate 18 extends to push the workpiece into the V-shaped slide 14. The outlet of the feeding pipe 16 is located above the clamping mechanism, and the V-shaped slide 14 can be raised and lowered between the clamping mechanism and the outlet of the feeding pipe 16. The V-shaped slide 14 receiving the workpiece moves to be coaxial with the chuck 1, and then the push rod 15 is used to push the workpiece to the chuck 1.

[0036] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
