Description

Technical Field

[0001] This utility model relates to the field of GIS processing equipment technology, and more specifically, to a tooling for rounding aluminum tubes for GIS. Background Technology

[0002] GIS (Gas Insulated Switchgear) is a type of switchgear that uses insulating gas for isolation and switching. In GIS, aluminum tubes are often used as conductor materials.

[0003] Due to the need for end-cutting during the processing of GIS aluminum tubes, the tube body is prone to elliptical deformation after end-cutting. In the past, workers had to manually support jacks to round the tube, which was a complicated operation. After rounding a section of the aluminum tube, the jacks had to be removed to move to the next section, resulting in high labor intensity for workers. In addition, the aluminum tube was prone to springback after being compressed during jacking operations, often requiring multiple repetitions, which was inefficient and could not meet the needs of batch processing. Summary of the Invention

[0004] The purpose of this utility model is to provide a calibrating fixture for GIS aluminum tubes that improves work efficiency and can automatically calibrate aluminum tubes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rounding fixture for aluminum tubes used in GIS, comprising a positioning base plate, a drive trolley, a fixed baffle, a movable baffle, an upper U-shaped bracket, and a lower U-shaped bracket;

[0006] The drive trolley is located on the positioning base plate and can move along the length of the positioning base plate;

[0007] The fixed baffle is fixedly installed at one upper end of the positioning base plate, and the movable baffle is slidably installed at the other upper end of the positioning base plate.

[0008] An inner support tube and a sliding tube are detachably installed between the fixed baffle and the movable baffle. The sliding tube is located above the inner support tube, and the inner support tube is used to pass through the aluminum tube.

[0009] A slide block is slidably disposed on the slide tube, and the upper U-shaped bracket is installed below the slide block;

[0010] The lower U-shaped bracket is installed above the drive trolley. The lower U-shaped bracket and the lower U-shaped bracket are used to clamp the aluminum tube on the surface of the inner support tube. The lower U-shaped bracket and the lower U-shaped bracket are fixedly connected by multiple telescopic rods.

[0011] Preferably, both the upper U-shaped bracket and the lower U-shaped bracket are composed of U-shaped brackets, hydraulic cylinders and support plates. The two hydraulic cylinders are respectively fixedly installed at the bottom of the slide and the upper part of the drive trolley. The two support plates are respectively fixedly connected to the piston shaft of the corresponding hydraulic cylinder. The two U-shaped brackets are respectively fixedly installed on the corresponding support plates. The two support plates are fixedly connected by multiple telescopic rods.

[0012] Preferably, positioning grooves are provided on both sides of the upper surface of the positioning base plate, and the positioning grooves are arranged along the length direction of the positioning base plate, so that the drive wheel of the driving trolley can be inserted into the corresponding positioning groove.

[0013] Preferably, a groove is provided at one end of the upper surface of the positioning base plate, a slider is slidably installed in the groove, a threaded hole is provided in the middle of the slider, the bottom of the movable baffle is fixedly connected to the slider, and a lead screw motor is fixedly installed at one end of the positioning base plate, the lead screw shaft of the lead screw motor is connected to the threaded hole of the slider.

[0014] Preferably, the driving trolley is an AGV with electric wheels.

[0015] Preferably, the positioning base plate and the movable baffle are fixedly installed with protruding columns on their inner sides, and the ends of the inner support tube and the sliding tube are inserted into the protruding columns at corresponding positions.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This invention uses two hydraulic cylinders to drive a U-shaped clamping plate to hold the aluminum tube, applying external pressure to round the tube. After one end of the tube is rounded, the two hydraulic cylinders retract, causing the U-shaped clamping plate to detach from the tube. Then, a trolley is driven to move to the deformed area at the next end of the tube, thus completing the rounding of the entire tube. This eliminates the need for manual installation of jacks, improving rounding efficiency and reducing worker labor intensity. In mass production, it effectively ensures the processing accuracy and dimensional deviation of batch products, enabling the aluminum tube to meet design requirements. Attached Figure Description
