Description

Technical Field

[0001] The utility model relates to the technical field of stretching devices, in particular to a stretching device for copper tube processing. Background Art

[0002] Copper tube, also known as red copper tube, is a kind of non-ferrous metal tube. It is a pressed and drawn seamless tube. Copper tube has good electrical and thermal conductivity. It is the main material for conductive accessories and heat dissipation accessories of electronic products. It has become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. Copper tube has strong corrosion resistance, is not easy to oxidize, and is not easy to react chemically with some liquid substances. It is easy to bend and shape. Copper tube can change its diameter through rolling processing to achieve the required diameter. In the process of copper tube processing, a copper tube processing stretching device is needed for stretching;

[0003] The announcement number CN216095616U discloses a stretching device for copper tube processing, including a bottom plate, a vertical plate fixedly connected to the top of one end of the bottom plate, a limit slide groove is provided on the top of the bottom plate, a plurality of limit slide blocks are slidably connected in the limit slide groove, a support plate is fixedly connected to the top of the limit slide block, a through slot is provided on one side of the support plate and the vertical plate, an arc-shaped clamping plate is provided in the through slot, a vertical rod is fixedly connected to the outer side of the arc-shaped clamping plate, and an end of the vertical rod away from the arc-shaped clamping plate passes through the inner wall of the through slot and is fixedly connected to a collar;

[0004] There may be two problems when using it. First, during the processing and stretching, it uses a cross bar to clamp the copper tube with multiple clamps. However, during the clamping process, due to its long length, the clamping force of the clamp at the farther end is weaker, which makes the copper tube easy to loosen during the clamping process. In addition, the staff is required to pull it out from one side after the stretching is completed, which makes the operation of the staff more complicated and thus reduces the work efficiency. Secondly, the support plate is driven to slide by the screw rod and stretching, so that its sliding range is smaller, thereby making the stretching range of the copper tube shorter, and the support block can only be controlled to slide to one side. Therefore, we propose a stretching device for copper tube processing. Utility Model Content

[0005] The utility model aims to provide a stretching device for copper tube processing, which solves the existing problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] As a further improvement of the above scheme, the sliding assembly includes a second motor, a drive shaft, a rotating shaft, a belt and a gear.

[0011] By adopting the above technical solution, the convex-shaped slide groove makes it easy to limit the fixed box and the fixed frame during the sliding process, so that the fixed box and the fixed frame are not easy to deviate during sliding, thereby making the copper tube more stable during the stretching process.

[0012] As a further improvement of the above solution, rotation grooves are provided at four corners of the bottom of the fixed box, and the gears are rotatably installed between the inner sides of the rotation grooves.

[0014] By adopting the above technical solution, the tooth groove makes it easy for the gear to cooperate with it after rotation, so that the gear can drive the fixed box to slide after rotation.

[0015] As a further improvement of the above solution, a threaded hole and a through hole are opened on one side of the sliding block, the screw rod is engaged with the threaded hole, and the outer diameter of the fixing rod is the same as the inner diameter of the through hole.

[0016] By adopting the above technical solution, the cooperation between the fixing rod and the through hole facilitates the limiting of the sliding block and the connecting block, making it difficult for the sliding block and the connecting block to rotate with the screw rod after being subjected to force, so that the sliding block and the connecting block can slide in relative directions.

[0017] As a further improvement of the above solution, the shapes of the clamping block and the supporting plate are both semicircular arcs, and rubber pads are provided on the outer sides of the clamping block and the supporting plate.

[0018] By adopting the above technical solution, the semicircular arc shape increases the contact area with the circular copper tube, and the rubber pad makes the copper tube more stable during the clamping process and not easy to loosen.
