Description

Technical Field

[0001] The present invention relates to the technical field of pipe end processing, in particular to a necking and denting device. Background Art

[0002] Copper pipe is a pressed and drawn seamless pipe with excellent thermal conductivity, making it the preferred material for heating and cooling pipes. To filter the liquid flowing through the copper pipe, filters are usually installed at the joints of the copper pipe.

[0003] Filters also use copper tubes as their base material, but because the filter's diameter is larger than the copper tube's, the filter's ends need to be chopped to fit over the tube. To facilitate welding, the filter's ends also need to be dented. The dents serve as a positioning mechanism, securing the filter and the tube relative to each other. Currently, however, these dents and dents require two separate machines, requiring frequent changes to complete each product. This results in low efficiency and occupies a significant amount of space. Summary of the Invention

In this embodiment, the loading drive member 113 is a linear cylinder, and the loading drive member 121 is a magnetically coupled rodless cylinder.

[0036] Furthermore, the loading and transferring member 112 is arranged near the discharge end of the loading and feeding member 111, and the loading and feeding member 111 is arranged to be inclined in the direction of the loading and transferring member 112, so that the workpiece in the loading and feeding member 111 can spontaneously move in the direction of the loading and transferring member 112 under the action of its own gravity, and there is no need to set up a material shifting assembly. The loading and transferring member 112 is connected to a slide rail, and a fixed slider is provided at the bottom of the loading support member 10, and the slide rail is slidably connected to the slider. The main body of the loading drive member 113 is fixedly mounted on the slide rail, and the output end of the loading drive member 113 is fixedly connected to the loading support member 10. Since the output end of the loading drive member 113 is fixedly connected to the loading support member 10, when the loading drive member 113 is working, it is the main body of the loading drive member 113 that moves, and drives the loading and transferring member 112 to move through the slide rail.

[0038] Furthermore, the feeding mechanism 1 also includes a material dividing assembly 14, which is arranged side by side with the material blocking assembly 13, and the material dividing assembly 14 is arranged away from the feeding transfer member 112. The material dividing assembly 14 is used to separate a single workpiece to prevent multiple workpieces from entering the feeding moving member. The material dividing assembly 14 includes a material dividing drive 141 and a material dividing member 142. The material dividing drive 141 is installed on the feeding support member 10 through a material dividing mounting member 140, and the output end of the material dividing drive 141 points to the feeding feeding member 111, and the material dividing member 142 is connected to the output end of the material dividing drive 141.

[0055] First, a single workpiece is separated by the dividing assembly 14, and the blocking driving member 131 drives the blocking member 132 away from the feeding member 111, and the workpiece falls into the feeding transfer member 112. The feeding driving member 113 drives the feeding transfer member 112 to move the workpiece to the clamping mechanism 2, and the loading driving member 121 drives the loading member 122 to move along the feeding transfer member 112 to mount the workpiece in the feeding transfer member 112 on the clamping member 213;

[0056] Next, the first driving member 33 is moved to drive the first carrier 31 to move, and the second driving member 34 is moved to drive the second carrier 32 to move, so that the necking mechanism 4 moves to the front of the clamping member 213, and the necking shaping member 425 is inserted into the workpiece.

[0057] Then, the clamping drive member 211 drives the clamping transmission group 212 to drive the clamping member 213 to rotate at high speed, and the workpiece rotates at high speed. The shrinking drive member 411 drives the shrinking member 424 to flip toward the shrinking shaping member 425, so that the shrinking member 424 presses against the rotating workpiece, repeatedly squeezing the workpiece to achieve shrinking.

[0058] After the shrinking is completed, the shrinking member 424 is reset, and the trimming driving member 431 drives the trimming member 432 to move, so that the trimming member 432 contacts the rotating workpiece to trim the cape on the workpiece;

[0059] Subsequently, the clamping driving member 211 stops working, the workpiece on the clamping member 213 stops rotating, and the second supporting member 32 is driven to move by the second driving member 34, so that the necking shaping member 425 is removed from the workpiece.

[0060] Then, the first driving member 33 is moved to drive the first carrier 31 to move, and the second driving member 34 is moved to drive the second carrier 32 to move, so that the punching mechanism 5 moves to the front of the clamping member 213, and the punching positioning member 52 is inserted into the workpiece;

[0061] Next, the two sets of denting assemblies 51 are simultaneously activated, and the denting driving member 511 drives the denting member 512 to move toward the denting positioning member 52. The denting member 512 presses against the workpiece to form a concave bump on the workpiece. After the denting process, the first driving member 33 drives the first carrier 31 to move, and the second driving member 34 drives the second carrier 32 to move, and the shrinking mechanism 4 and the denting mechanism 5 retreat.

[0062] Finally, the blanking drive 61 drives the blanking transmission group 62 to drive the blanking receiving part 63 to move to the front of the clamping component 21, and the material return drive 221 drives the material return part 222 to move toward the clamping part 213 to eject the workpiece on the clamping part 213, and the ejected workpiece will fall into the blanking receiving part 63, and the blanking drive 61 drives the blanking transmission group 62 to drive the blanking receiving part 63 to reset. After the blanking receiving part 63 is reset, the workpiece in the blanking receiving part 63 will fall into the blanking collecting part 64, and the workpiece falls into the material frame along the blanking collecting part 64.

[0063] This cycle repeats itself.

[0064] To sum up, this shrinking and denting device integrates the shrinking mechanism and the denting mechanism into one. One device can complete the shrinking and denting processing. There is no need to transport materials back and forth or change equipment, which simplifies the processing flow, saves processing time, effectively improves work efficiency, and also saves equipment space.

[0065] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
