Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, in particular to a copper tube positioning bulge forming device. Background Art

[0002] The structure of the air conditioning water collecting pipe is as shown in the attached instruction manual. Figure 4 As shown, it includes a water collecting pipe body and a plurality of copper pipes fixed on the water collecting pipe body. The copper pipes are first inserted into the water collecting pipe and then fixed to the water collecting pipe by welding. Since the copper pipe holes on the water collecting pipe are generally slightly larger than the outer diameter of the copper pipes, the copper pipes are likely to fall off automatically after being inserted, which increases the difficulty of the subsequent welding work. In addition, the welder needs to fix the copper pipe during the welding process, which increases the safety hazard of welding and reduces the welding efficiency. In order to prevent the copper pipe from falling before welding, a positioning protrusion is set on the copper pipe. Before welding, the positioning protrusion can be knocked into the copper pipe hole of the water collecting pipe by tapping, so that the copper pipe can be positioned. Therefore, there is an urgent need for a forming device for the copper pipe positioning protrusion. Utility Model Content

[0003] The purpose of the utility model is to provide a copper tube positioning protrusion forming device, which can quickly and conveniently form a positioning protrusion at the corresponding position of the copper tube through the cooperation of the forming pressure rod and the die groove and the die hole, thereby facilitating the subsequent welding work of the copper tube and improving the welding efficiency.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] Insert the small section of copper tube into the forming pressure rod, and the lifting column moves downward to drive the forming pressure rod to move downward. The forming pressure rod drives the copper tube to move downward and insert it into the mold groove. Then the forming pressure rod continues to move downward to press a positioning convex point on the side wall of the copper tube through the protrusion. The positioning convex point can facilitate the positioning work between the copper tube and the water collection pipe before subsequent welding.

[0008] The utility model is further configured as follows: a rack arranged parallel to the lifting column is fixed on the lifting column, the rack is meshed with a gear, the gear is fixed to the middle of the rotating shaft, and the rotating shaft is rotatably connected to the frame;

[0009] A handle is fixed on one end of the rotating shaft passing through the frame.

[0010] The handle drives the rotating shaft to rotate, the rotating shaft drives the gear to rotate, the gear drives the rack to move downward, and the rack drives the lifting column to move downward, thereby completing the downward forming work of the forming machine.

[0011] The utility model is further configured as follows: a limit support plate is fixed on the upper end of the lifting column, a vertically arranged adjusting screw is screwed on the limit support plate, and the adjusting screw is directly facing the upper end plane of the frame.

[0012] The downward movement of the lifting column can be limited by adjusting the screw to prevent the copper tube from being broken due to overpressure on the formed pressure rod; at the same time, the relative height of the adjusting screw can be changed by screwing the adjusting screw to the limit support plate, thereby adjusting the lowest downward position of the lifting column.

[0013] The utility model is further configured such that the top end of the lifting column is fixed to the bottom end of the tension spring, the top end of the tension spring is fixed to the spring bracket, and the spring bracket is fixed to the frame. After the copper tube positioning protrusion is completed, the handle is released, and the lifting column automatically moves upward under the action of the tension spring, while the lifting column can be stopped at a certain height, facilitating the installation and removal of the copper tube.

[0014] The utility model is further configured as follows: the forming pressure rod includes a round rod portion and a square column portion;

[0015] The lower end of the lifting column is formed with a front sunken surface, and the front sunken surface is formed with a square sunken hole. The square column part is inserted into and fixed in the square sunken hole.

[0016] The protrusion can be positioned by the cooperation of the square column part and the square countersunk hole, thereby preventing the forming pressure rod from rotating freely.

[0017] The utility model is further configured such that a through hole is formed on the bottom surface of the square countersunk hole, a screw is inserted into the through hole, and the screw is screwed onto the square column portion. The screw facilitates the locking of the square column portion, and when the forming pressure rod is to be replaced, the worker can push the forming pressure rod out from the rear end through the through hole.

[0018] The utility model is further configured as follows: a plurality of die grooves are arranged in parallel on the lower die base, and the sizes of the plurality of die grooves are different.

[0019] The lower die base can move on the frame and be fixed to the frame by screws. By setting a plurality of die grooves, the positioning convex forming work can be performed on copper tubes with various diameters.

[0020] The outstanding effects of the utility model are:

[0021] Compared with the existing technology, through the cooperation of the forming pressure rod, the die groove and the die hole, the positioning protrusion can be quickly and conveniently formed at the corresponding position of the copper tube, which facilitates the subsequent welding work of the copper tube and improves the welding efficiency.
