Description

Technical Field

[0001] This application relates to the basic non-cutting machining or processing of metal plates, tubes, rods or profiles; in the field of stamping metal technology, it specifically relates to a copper tube diameter reducing device. Background Technology

[0002] When copper pipes undergo diameter reduction, they are typically clamped by a fixture and then pass through a reducing head at one end for diameter reduction. For example, the copper pipe diameter reducing device disclosed in utility model patent document CN208427638U includes a base frame, a first cylinder, a second cylinder, a base plate, a first cylinder fixing block, a second cylinder fixing block, a clamping mold, a reducing module, and a handle. The first cylinder fixing block is installed at the top of the base frame, and the first cylinder is installed below the first cylinder fixing block. The second cylinder fixing block is fixedly mounted on the base plate. The second cylinder and the second cylinder fixing block are connected and fixedly mounted on the base plate. The clamping mold is fixed on the base plate, below the first cylinder and to one side of the second cylinder. The reducing module is connected to the second cylinder. The handle is mounted on the base plate and connected to both the first and second cylinders.

[0003] After the copper tube reducing device completes the reduction of a copper tube, the copper tube that has been expanded is usually manually removed from the open clamp, and then the copper tube to be reduced is placed back into the open clamp. The clamp then re-clamps the copper tube to be reduced and waits for the reduction to occur. This manual labor is intensive, and each removal and repositioning of the copper tube takes a certain amount of time, which limits the overall production speed. Summary of the Invention

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a copper tube diameter reducing device, the technical solution of which includes:

[0005] A copper tube reducing device includes a frame and a reducing feeding mechanism, a reducing unloading mechanism, an upper clamp, and a lower clamp mounted on the frame. The upper and lower clamps have limiting slots for accommodating copper tubes on their respective sides. The reducing feeding mechanism and the reducing unloading mechanism are located on opposite sides of the limiting slots. The reducing feeding mechanism has feeding claws, and the reducing unloading mechanism has unloading claws. The lower clamp and the upper clamp have slots communicating with the limiting slots on their sides closest to the reducing unloading mechanism. When the upper and lower clamps hold a copper tube, the reducing unloading mechanism drives the unloading claws to extend into the slots and hold the copper tube. After the upper clamp moves away from the lower clamp, the reducing unloading mechanism drives the unloading claws to hold the copper tube and move it out of the limiting slot on the lower clamp. Simultaneously, the reducing feeding mechanism drives the feeding claws to hold the next copper tube and place it into the limiting slot on the lower clamp.

[0023] Reference Figure 1-3 This application presents an embodiment of a copper tube reducing device, which includes:

[0024] The frame 10 includes a variable diameter feeding mechanism 20, a variable diameter unloading mechanism 30, a variable diameter head, an upper clamp 40, and a lower clamp 50 mounted on the frame 10. The upper clamp 40 and lower clamp 50 each have a limiting groove 60 for accommodating copper tubes on their adjacent sides. The variable diameter head (not shown) is located at one end of the limiting groove 60. The variable diameter feeding mechanism 20 and the variable diameter unloading mechanism 30 are located on opposite sides of the limiting groove 60. The variable diameter feeding mechanism 20 has a feeding jaw 21, and the variable diameter unloading mechanism 30 has a unloading jaw 31. The lower clamp 50 and the upper clamp 40... On one side near the variable diameter feeding mechanism 30, there are slots 70 that communicate with the limiting through groove 60. The variable diameter feeding mechanism 30 is used to drive the feeding claw 31 to extend into the slot 70 and clamp the copper tube when the upper clamp 40 and the lower clamp 50 are clamping the copper tube. After the upper clamp 40 moves away from the lower clamp 50, the variable diameter feeding mechanism 30 drives the feeding claw 31 to clamp the copper tube and move it out of the limiting through groove 60 on the lower clamp 50. At the same time, the variable diameter feeding mechanism 20 drives the feeding claw 21 to clamp the next copper tube and put it into the limiting through groove 60 on the lower clamp 50.

[0025] The variable diameter head is mounted on the frame 10 via a variable diameter drive mechanism, and the upper clamp 40 is mounted on the frame 10 via a clamping drive mechanism. (Refer to the attached diagram.) Figure 1 As shown, when the upper clamp 40 and lower clamp 50 close and clamp the copper tube, the diameter-changing drive mechanism drives the diameter-changing head to move closer to the upper clamp 40 and lower clamp 50 to change the diameter of the copper tube. When the diameter-changing head changes the diameter of the copper tube, since the lower clamp 50 and upper clamp 40 are provided with slots 70 on their sides, the two fingers of the unloading claw 31 respectively insert into the two slots 70 and clamp the copper tube. The diameter-changing loading mechanism 20 drives the loading claw 21 to clamp the next copper tube.

[0026] After the copper tube undergoes diameter change, the clamping drive mechanism drives the upper clamp 40 to move upward. Then, the diameter-changing unloading mechanism 30 drives the unloading jaws 31 to move away from the lower clamp 50 while holding the copper tube, thus removing the copper tube that has undergone diameter change. At the same time, the diameter-changing loading mechanism 20 drives the loading jaws 21 to move closer to the lower clamp 50 and places the next copper tube in the lower clamp 50. This achieves automatic loading and unloading of copper tubes, and the simultaneous loading and unloading of copper tubes helps to improve production speed.

[0027] Preferably, the variable diameter feeding mechanism 20 includes a first two-dimensional drive mechanism 22. The feeding gripper 21 is mounted on the frame 10 through the first two-dimensional drive mechanism 22. The feeding gripper 21 has two fingers, and each of the two fingers is equipped with an L-shaped clamping member 23. One end of the clamping member 23 is connected to the finger, and the other end is bent downward so that the other ends of the two clamping members 23 can extend between the upper clamp 40 and the lower clamp 50 to place the copper tube in the limiting through groove 60 of the lower clamp 50.

[0028] Based on the above, as a preferred embodiment, in order to enable the feeding gripper 21 to smoothly place the copper tube into the limiting through groove 60, the upper end of the lower clamp 50 is provided with a groove 51 that is distributed opposite to the slot 70. The groove 51 is used for the clamping member 23 to be inserted and clamp the copper tube.

[0029] When the loading jaw 21 clamps and places the copper tube, the two fingers of the loading jaw 21 are respectively placed into the slot 70 and the groove 51 to place the copper tube.

[0030] Specifically, the variable diameter feeding mechanism 30 includes a second two-dimensional drive mechanism 32 mounted on the frame 10, and the feeding gripper 31 is mounted on the second two-dimensional drive mechanism 32. The first two-dimensional drive mechanism 22 is used to drive the feeding gripper 21 to perform two-dimensional movement in the vertical plane, and the second two-dimensional drive mechanism 32 is used to drive the feeding gripper 31 to perform two-dimensional movement in the vertical plane.

[0031] The first two-dimensional drive mechanism 22 is also equipped with a feeding auxiliary gripper, and the second two-dimensional drive mechanism 32 is also equipped with a discharging auxiliary gripper. The feeding auxiliary gripper and the feeding gripper 21 are distributed at intervals along the length direction of the limiting through groove 60, and the discharging auxiliary gripper and the discharging gripper 31 are distributed at intervals along the length direction of the limiting through groove 60, so as to stably clamp the copper tube.

[0032] Preferably, the system also includes a copper tube feeding device 80, which is disposed on one side of the frame 10 and used to feed copper tubes one by one. The variable diameter feeding mechanism 20 is used to grab copper tubes above the copper tube feeding device 80. Feeding devices for feeding copper tubes one by one are existing technology in the field, and their structure and working principle will not be described in detail in this embodiment.

[0033] Furthermore, the frame 10 is also equipped with a feeding receiving device 90, which is used to receive the copper tube held by the feeding gripper 31, facilitating the feeding of the copper tube with reduced diameter. Specifically, the feeding receiving device 90 includes two receiving platforms 91, which are spaced apart along the length of the limiting through groove 60 on the frame. The second two-dimensional drive mechanism 32 drives the feeding gripper 31 to place the copper tube it holds onto the two receiving platforms 91, completing the feeding of the copper tube with reduced diameter. After the copper tube is placed on the two receiving platforms 91, it can be transferred to the collection box manually or by a robot. Referring to the attached drawings, the receiving platform 91 is also provided with an arc-shaped groove to facilitate the positioning of the copper tube on the receiving platform 91.

[0034] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
