Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a stainless steel pipe roller press. Background Art

[0002] As the name implies, the diameter reducing machine is to send the round steel, threaded steel and other parts that need to be reduced into a special mold for cold shrinkage and molding. The density of the steel in the reduced and compressed part can be greatly increased, thereby improving the compressive strength of the material. The plasticity and impact toughness remain unchanged, making the strength of the threaded part and the rod part consistent.

[0003] There are many existing technologies for stainless steel pipe roller presses, such as:

[0005] It can be seen that most stainless steel pipe rolling machines include a box body, and a conical movable plate is arranged in the box body. The shape of the conical movable plate is used to squeeze and shrink the end of the steel pipe, thereby achieving diameter reduction of the steel pipe. However, since the conical movable plate can only move in one direction, the diameter reduction size of the steel pipe cannot be controlled, and the diameter reduction size of the steel pipe may be too large or too small, resulting in the inability to splice the steel pipe.

[0006] In view of this, we propose a stainless steel pipe roller press. Utility Model Content

By arranging a conveying component in the transport cavity, the steel pipe is transported by the conveying component, and the steel pipe is squeezed with the adjusting component, so that one end of the steel pipe is reduced in diameter.

[0009] Therefore, the utility model provides a stainless steel pipe rolling machine, including a frame, wherein a transport cavity and a diameter reduction cavity are provided in the frame, the transport cavity is provided with a conveying component for conveying the steel pipe, the diameter reduction cavity is provided with an adjusting component for adjusting the diameter reduction size of the steel pipe, the adjusting component includes a conical plate composed of four movable plates, and a hydraulic rod is fixed between the movable plate and the transport cavity.

[0012] As a further improvement of the technical solution, the active rotating wheel includes a rotating shaft, and a motor for driving the active rotating wheel to rotate is fixed on the top of the rotating shaft of the active rotating wheel.

[0013] As a further improvement of the technical solution, the active rotating wheel fixes one end of the steel pipe and transmits it to the diameter reduction cavity, and one end of the steel pipe is extruded and discharged from the through hole of the conical plate composed of four movable plates.

In the stainless steel pipe roller press, an adjustment component is arranged in the diameter reduction chamber, and the hydraulic movement of the hydraulic rod is used to make the four movable plates of the adjustment component open and close, thereby adjusting the aperture size of the conical plate discharging the steel pipe, which is beneficial to control the diameter reduction size of the steel pipe during the steel pipe diameter reduction operation.

[0023] Most stainless steel pipe rolling machines include a box body, in which a conical movable plate is arranged. The shape of the conical movable plate is used to squeeze and shrink the end of the steel pipe, thereby reducing the diameter of the steel pipe. However, since the conical movable plate can only move in one direction, the diameter reduction size of the steel pipe cannot be controlled, and the diameter reduction size of the steel pipe may be too large or too small, resulting in the inability to splice the steel pipe.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides a stainless steel pipe rolling machine, including a frame 100, wherein a transport chamber 101 and a diameter reduction chamber 102 are provided in the frame 100. Considering the transportation of the steel pipe, a transport assembly 110 for transporting the steel pipe is provided in the transport chamber 101. Considering the diameter reduction of the steel pipe, an adjustment assembly 120 for adjusting the diameter reduction size of the steel pipe is provided in the diameter reduction chamber 102. Considering the control of the diameter reduction size of the steel pipe, the adjustment assembly 120 includes a conical plate composed of four movable plates 121, and a hydraulic rod 122 is fixed between the movable plate 121 and the transport chamber 101.

[0025] The improvement of this embodiment lies in that an adjusting component 120 is arranged in the reducing cavity 102, and the hydraulic movement of the hydraulic rod 122 is utilized to make the four movable plates 121 of the adjusting component 120 open and close, thereby adjusting the aperture size of the conical plate for discharging the steel pipe, which is beneficial to controlling the reduced diameter size of the steel pipe during the reduction operation of the steel pipe, and a conveying component 110 is arranged in the transport cavity 101, and the steel pipe is transported by the conveying component 110, and the steel pipe is squeezed with the adjusting component 120, so that one end of the steel pipe is reduced in diameter.

[0026] Considering the introduction of the connection relationship in the adjustment component 120 and the introduction of the conveying component 110, the second embodiment of the present utility model is shown.

[0027] One end of the movable plate 121 is rotatably connected to one side of the inner cavity of the transport chamber 101, one end of the hydraulic rod 122 is rotatably connected to the inner cavity of the transport chamber 101, and the other end of the movable plate 121 is rotatably connected to the piston rod of the hydraulic rod 122. When the hydraulic rod 122 performs hydraulic movement, the piston rod drives the movable plate 121 to rotate, so that the size of the through hole of the conical plate composed of four movable plates 121 is changed. The conveying assembly 110 is composed of a group of active rotating wheels 112 for clamping and conveying steel pipes and a plurality of groups of auxiliary steel pipes. The driven rotating wheel 113 is used for conveying, and the driving rotating wheel 112 is arranged near the delivery port of the transport chamber 101. The driving rotating wheel 112 includes a rotating shaft. A motor 111 for driving the driving rotating wheel 112 to rotate is fixed on the top of the rotating shaft of the driving rotating wheel 112. The output shaft of the motor 111 rotates to drive the driving rotating wheel 112 to rotate, so that the driving rotating wheel 112 fixes one end of the steel pipe and conveys it to the reducing chamber 102. Finally, one end of the steel pipe is extruded and discharged from the through hole of the conical plate composed of four movable plates 121.

[0028] In summary, the working principle of this solution is as follows:

[0029] Start the hydraulic rod 122, and the hydraulic rod 122 performs hydraulic movement, so that the piston rod drives the movable plate 121 to rotate, thereby changing the size of the through hole of the conical plate composed of the four movable plates 121. After adjusting the size of the through hole, start the motor 111, and the output shaft of the motor 111 rotates to drive the active rotating wheel 112 to rotate, so that one end of the steel pipe is put into the delivery port of the transport chamber 101. The active rotating wheel 112 fixes one end of the steel pipe and transmits it to the reduction chamber 102. Finally, the steel pipe is squeezed out from the through hole of the conical plate composed of the four movable plates 121. When the appropriate reduction length is reached, turn off the motor 111, and start the hydraulic rod 122 again to open the four movable plates 121 to take out the steel pipe.
