[0004] To address the aforementioned technical problems, this utility model provides an integrated machine for straightening and cutting stainless steel seamless tubes. This solves the problem that in the existing stainless steel seamless tube processing, straightening and cutting are usually performed by different equipment, which not only increases equipment costs and floor space but also leads to low production efficiency.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A stainless steel seamless tube straightening and cutting integrated machine includes a base; a groove is formed at the middle of the top of the base, and a T-shaped bracket is slidably connected in the groove. A threaded hole is formed at the front end of the bottom of the T-shaped bracket. A screw is rotatably connected at the front end of the groove of the base, and the screw is located in the threaded hole of the T-shaped bracket. An adjusting frame is fixedly connected at the middle of the rear end of the top of the base. The middle of the adjusting frame is designed to be through, and a bevel gear ring is rotatably connected at the middle of the interior of the adjusting frame. A bevel gear is rotatably connected at the upper interior of the adjusting frame, and the bevel gear meshes with the bevel gear ring. A spiral block is provided at the front end of the bevel gear ring. A sliding groove is formed on both the left and right sides of the front end of the adjusting frame, and a slider is slidably connected in each of the two sliding grooves. The two sliders are symmetrically designed, and an arc-shaped block is provided at the rear end of the slider. The arc-shaped blocks of the two sliders mesh with the spiral block of the bevel gear ring. A straightening frame is fixedly installed at the front end of each slider. A motor A is fixedly installed at the front end of the straightening frame, and the rear end of the rotating shaft of motor A is fixedly connected to the front end of the straightening roller.

[0007] According to one embodiment of the present invention, the straightening roller is located inside the straightening frame, and the T-shaped bracket is located in the middle of the two straightening rollers.

[0008] According to one embodiment of the present invention, the rear end of the base is fixedly connected to the front end of the limiting frame, and an mounting bracket is fixedly installed inside the limiting frame. The middle of the mounting bracket is designed to pass through, and the mounting bracket is located directly behind the adjusting frame.

[0009] According to one embodiment of the present invention, four slides are provided at the rear end of the mounting bracket. The four slides are arranged in a cross shape. A motor B is fixedly installed on the outer side of each slide. The shaft of the motor B is threaded. A limiting block is slidably connected to each slide. A threaded hole is opened on the outer side of each limiting block. The shaft of the motor B is located in the threaded hole of the limiting block.

[0010] According to one embodiment of the present invention, a lifting frame is fixedly connected to the top middle position of the limiting frame, the inner position of the lifting frame is slidably connected to the upper position of the front end of the L plate, a threaded hole is opened at the top front end position of the L plate, and a motor C is fixedly installed at the top middle position of the lifting frame.
