Technical Field
[0001] The utility model relates to the technical field of bearing steel pipe production, in particular to a novel drawing and roll pressing device for bearing steel pipes. Background Technique
[0002] Bearing steel pipes are the processing raw materials for bearings, generally seamless steel pipes processed by hot rolling or cold rolling processes. Before cold drawing, a drawing head is heated and forged at the end of the seamless steel pipe to facilitate the drawing of pipe fittings. During drawing, the rotation of the roll pressing wheel is used to draw and process the fed steel pipe.
[0003] The existing roll pressing devices generally use roll presses with a single structure. However, due to the different size specifications of bearing steel pipes, different roll pressing distances are required. Conventional roll pressing devices cannot perform drawing and roll pressing on bearing steel pipes of different specifications. In addition, there is no structure for positioning the bearing pipes on the roll presses, resulting in reduced applicability of the roll pressing devices. For this reason, a novel drawing and roll pressing device for bearing steel pipes is proposed. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0023] Refer to Figure 1 , a new type of bearing steel pipe drawing and rolling device, including a fixed frame 1. Inside the fixed frame 1, there are an upper pressure roller 2 and a lower pressure roller 3. Both the upper pressure roller 2 and the lower pressure roller 3 are rotatably arranged inside the fixed frame 1. One side of the fixed frame 1 is fixedly provided with a housing 4. One end of the upper pressure roller 2 and one end of the lower pressure roller 3 both extend into the housing 4. The housing 4 is provided with a driving mechanism connected to the upper pressure roller 2 and the lower pressure roller 3. The driving mechanism can drive the upper pressure roller 2 and the lower pressure roller 3 to rotate and complete the drawing and rolling process of the bearing steel pipe. Both the upper pressure roller 2 and the lower pressure roller 3 adopt a multi-segment structure, and the diameter of each segment is different, which can ensure that bearing steel pipes of different specifications are placed between the upper pressure roller 2 and the lower pressure roller 3 with different spacings, so as to be able to roll bearing steel pipes of different specifications, improving the applicability of the rolling device; on each roller wall of the upper pressure roller 2 and each roller wall of the lower pressure roller 3, there are symmetrically adjustable limit retaining rings 5. During the rolling process, the limit retaining rings 5 can limit both sides of the bearing steel pipe to be rolled, increasing the stability of the drawing and rolling.
[0024] Refer to Figure 1 , the driving mechanism includes a motor 6 and two gears 7. One end of the upper pressure roller 2 and one end of the lower pressure roller 3 both extend into the housing 4 and are respectively fixedly connected to the two gears 7. The two gears 7 are meshed with each other. The motor 6 is fixedly arranged on the side wall of the housing 4, and the output end of the motor 6 is fixedly connected to one end of the lower pressure roller 3. When the motor 6 works, it can drive the lower pressure roller 3 to rotate. Since the upper pressure roller 2 and the lower pressure roller 3 are meshed through the two gears 7, the upper pressure roller 2 and the lower pressure roller 3 can rotate relatively. The motor 6 adopts a variable-speed motor, enabling the motor 6 to drive the upper pressure roller 2 and the lower pressure roller 3 to rotate at a variable speed.
[0025] Refer to Figure 1-3, two mounting rings 8 are symmetrically and fixedly arranged on the side wall of the limit retaining ring 5. A bolt 9 is inserted into the side wall of the mounting ring 8. Each section of the roller wall of the upper pressure roller 2 and each section of the roller wall of the lower pressure roller 3 are provided with screw holes 10 that cooperate with the bolt 9. The number of the screw holes 10 is multiple, and the multiple screw holes 10 are distributed along the length directions of the upper pressure roller 2 and the lower pressure roller 3. When bearing steel pipes of different specifications are being rolled by the pressure rollers, the bolt 9 can be loosened so that the limit retaining ring 5 moves on the upper pressure roller 2 and the lower pressure roller 3, thereby enabling the distance between the two limit retaining rings 5 on both sides to be adjustable, and being applicable to bearing steel pipes of different specifications.
[0026] Refer to Figure 1 , a residue collection box 11 is fixedly arranged at the bottom of the fixing frame 1. Waste residues will be generated during the rolling process of the bearing steel pipe. At this time, they are collected by the residue collection box 11 to avoid polluting the bottom of the fixing frame 1.
[0027] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
