Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum tube processing. Specifically, it particularly relates to a core-pulling mandrel tooling for aluminum tubes. Background Art
[0002] Thin and light aluminum tubes are widely used in the production and processing industries. However, traditional thin and light aluminum tubes are extremely prone to deformation during the processing. Therefore, before processing, a polyurethane mandrel is generally inserted to avoid the deformation that is extremely likely to occur during the processing. However, the traditional method of inserting the mandrel is manual core-pulling, with a fixed working position, low automation, and low efficiency. How to effectively solve the above problems is an important issue that needs to be solved during the current aluminum tube processing. Content of the Utility Model
[0003] The purpose of the utility model is to solve the drawbacks existing in the prior art, and a core-pulling mandrel tooling for aluminum tubes is proposed, which includes a frame. On one side of the top of the frame, there is a core mandrel introduction cylinder facilitating the introduction of the polyurethane mandrel, and on the other side, there is a core mandrel export cylinder. The telescopic end of the core mandrel introduction cylinder abuts against a polyurethane mandrel, and the other end of the polyurethane mandrel corresponds to the axis of the aluminum tube taken by the manipulator.
[0004] Preferably, a polyurethane guide groove is also fixedly installed on the frame of the telescopic end of the core mandrel introduction cylinder.
[0005] Preferably, the cross-section of the polyurethane guide groove is V-shaped.
[0006] Preferably, a mounting seat is arranged at the bottom of the frame, and a foot cup facilitating the adjustment of the overall height of the frame is slidably installed on the mounting seat.
[0007] Preferably, the foot cup includes a floor anchor and a limit screw. The limit screw passes through a limit through hole opened on the mounting seat, and limit nuts are arranged on the upper and lower sides of the mounting seat.
[0008] Preferably, fixing through holes facilitating the driving of floor anchor bolts are opened on the floor anchor, and floor anchor bolts are passed through the fixing through holes.
[0009] Preferably, a mounting plate facilitating the external connection with other mechanisms is arranged in the middle of the frame.
[0010] Compared with the existing technology, the beneficial effects of the present utility model are as follows: The overall workbench frame is welded by square tubes and connecting plates, with a stable and light framework; the provided foot cups can facilitate the height adjustment and position fixation of the entire frame; the polyurethane guide groove arranged in a V shape has a guiding effect on the mandrel; by respectively arranging a mandrel inlet cylinder and a mandrel outlet cylinder on the left and right sides of the top of the frame, it is convenient to fill the polyurethane mandrel into the aluminum tube. This mandrel piercing and drawing tool replaces the original manual operation process of piercing and drawing polyurethane, not only ensuring the safety of personnel, but also greatly accelerating the production rhythm, improving production capacity, and enhancing the degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 FIG. is a schematic diagram of the overall structure of a mandrel piercing and drawing tool for aluminum tubes proposed by the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0013] Referring to the figure, this embodiment provides a mandrel piercing and drawing tool for aluminum tubes, including a frame 1. On one side of the top of the frame 1, there is a mandrel inlet cylinder 2 for facilitating the introduction of the polyurethane mandrel, and on the other side, there is a mandrel outlet cylinder 3. The telescopic end of the mandrel inlet cylinder 2 abuts against a polyurethane mandrel 4, and the other end of the polyurethane mandrel corresponds to the axis of the aluminum tube held by the manipulator.
[0014] Furthermore, a polyurethane guide groove 5 is fixedly installed on the frame corresponding to the telescopic end of the mandrel inlet cylinder 2.
[0015] Furthermore, the cross-section of the polyurethane guide groove 5 is V-shaped.
[0016] Furthermore, an installation seat 6 is arranged at the bottom of the frame 1, and a foot cup for facilitating the adjustment of the overall height of the frame 1 is slidably installed on the installation seat 6.
[0017] Furthermore, the foot cup includes a floor anchor 7 and a limit screw 8. The limit screw 8 passes through a limit through hole opened on the installation seat 6, and limit nuts 11 are arranged on the upper and lower sides of the installation seat 6.
[0018] Furthermore, a fixing through hole 9 for facilitating the driving of the floor anchor screw is opened on the floor anchor 7, and a floor anchor bolt is passed through the fixing through hole.
[0019] Furthermore, an installation plate 10 for facilitating the external connection of other mechanisms is arranged in the middle of the frame 1.
[0020] Working principle:
[0021] During specific use, first place the selected polyurethane mandrel to be inserted into the polyurethane guide groove 5. Then adjust the robotic arm to place the aluminum tube at one end of the polyurethane guide groove 5 away from the mandrel insertion cylinder 2. Next, start the mandrel insertion cylinder 2. The telescopic rod of the mandrel insertion cylinder 2 slowly inserts the polyurethane mandrel 4 into the aluminum tube. Then the robotic arm takes the workpiece with the inserted polyurethane mandrel 4 to the processing area for the next processing step. After processing, if it is necessary to export the polyurethane mandrel 4 from the inside of the aluminum tube, operate the robotic arm, place the workpiece between the polyurethane guide groove 5 and the mandrel export cylinder 3, and adjust the axis of the telescopic shaft of the mandrel export cylinder 3 and the axis of the polyurethane mandrel. Finally, start the mandrel export cylinder 3, and the telescopic rod of the mandrel export cylinder 3 slowly exports the polyurethane mandrel.
[0022] In the above embodiments and working principles, the overall workbench frame is welded by square tubes and connecting plates, with a stable and light framework. The set foot cups can facilitate the height adjustment and position fixation of the entire frame. The polyurethane guide groove arranged in a V shape has a guiding effect on the mandrel. By respectively arranging the mandrel insertion cylinder and the mandrel export cylinder on the left and right sides at the top of the frame, it is convenient to fill the polyurethane mandrel into the aluminum tube. This core-pulling mandrel tooling replaces the original manual core-pulling polyurethane operation process, not only ensuring the safety of personnel, but also greatly accelerating the production rhythm, improving production capacity, and enhancing the degree of automation.
[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
