Description

Technical Field

[0001] This utility model relates to the field of shaft parts manufacturing technology, and in particular to a wedge cross rolling mill. Background Technology

[0002] Wedge cross rolling mills are suitable for rolling variable cross-section rotating bodies. Two rolls with wedge-shaped passes rotate in the same direction along the direction of wedge advance, gradually rolling the billet into a variable cross-section rotating body. The wedge cross rolling mill mainly consists of a main motor, a transmission device, and a working stand. The working stand of the wedge cross rolling mill includes rolls, an adjustment mechanism, a guide device, and a frame.

[0003] When processing shaft parts in a wedge cross rolling mill, a large amount of oxide scale detaches from the shaft parts and falls onto the mill's base, making cleaning inconvenient and impacting the workshop environment. Based on these technical problems, the inventors analyzed the structural characteristics of the wedge cross rolling mill and discovered a significant height difference between the lower roll and the base. Therefore, utilizing this height difference, the inventors added an oxide scale cleaning device between the lower roll and the base, effectively solving the oxide scale cleaning problem in the wedge cross rolling mill. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a wedge cross rolling mill.

[0005] This utility model is achieved through the following technical solution: a wedge cross rolling mill is provided, including a base and a frame mounted on the base. An upper roll and a lower roll are mounted on the frame. An oxide scale cleaning device is mounted on the panel of the base, and the oxide scale cleaning device is located below the lower roll. The oxide scale cleaning device includes a collection box, the top surface of which is inclined and multiple collection ports are provided on the inclined surface. One end of the collection pipe is connected to the collection box, and the other end is connected to an industrial vacuum cleaner.

[0006] Preferably, the rolled shaft parts will fall onto the inclined plane and roll along the inclined plane to one side of the wedge cross rolling mill. In order to prevent the shaft parts from deviating when rolling, limit baffles are provided on both sides of the inclined plane. The limit baffles can play a restraining role when the shaft parts roll.

[0007] Preferably, during use, some oxide scale may fall onto the inclined surface but cannot enter the collection port. In order to enable this oxide scale to enter the collection port smoothly, an auxiliary cleaning mechanism is set between the two limiting baffles. The auxiliary cleaning mechanism includes a mounting plate and a brush fixed on the mounting plate, with the brush in contact with the inclined surface.

[0008] Preferably, a linear slide rail is installed on the inner side of each limiting baffle, the linear slide rail is arranged along the length of the limiting baffle, and a slider is installed on each linear slide rail. The two ends of the mounting plate are respectively connected to two sliders. When the mounting plate is held by hand and slids along the linear slide rail, the oxide scale retained on the inclined surface can be swept into the collection port by a brush.

[0009] Preferably, in order not to affect the rolling of shaft parts, when cleaning is not required, the brush is located at the higher end of the inclined plane. In order to achieve brush positioning, a positioning bolt for tightening the inclined plane is threaded onto the mounting plate. The brush positioning is achieved by using the positioning bolt to tighten the inclined plane.

[0010] Preferably, a handrail is installed on the top surface of the mounting plate to facilitate its movement.

[0011] Preferably, to prevent the cut material from falling into the collection box, an intercepting net is installed at each collection port.

[0012] Preferably, ear plates are provided on both sides of the bottom surface of the collection box, and each ear plate is connected to the panel by bolts.

[0013] The beneficial effects of this utility model are as follows:

[0014] This application utilizes the height difference between the lower roller and the panel, and uses this height difference to add an oxide scale cleaning device between the two. By using the oxide scale cleaning device in conjunction with the auxiliary cleaning mechanism, oxide scale cleaning can be easily achieved. Attached Figure Description

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0022] like Figure 1-4 As shown, this utility model includes a base 5 and a frame 1 mounted on the base 5. An upper roller 2 and a lower roller 3 are mounted on the frame 1. An oxide scale cleaning device is mounted on the panel 4 of the base 5, located below the lower roller 3. The oxide scale cleaning device includes a collection box 6. The top surface of the collection box 6 is inclined, and multiple collection ports 14 are provided on the inclined surface. One end of a collection pipe 7 is connected to the collection box 6, and the other end is connected to an industrial vacuum cleaner. The industrial vacuum cleaner adopts an existing structure. The industrial vacuum cleaner generates negative pressure to suck the fallen oxide scale into the collection box 6 through the collection ports 14, and then sends it into the industrial vacuum cleaner for collection and processing through the collection pipe 7.

[0023] In this embodiment, the rolled shaft parts will fall onto the inclined plane and roll along the inclined plane to one side of the wedge cross rolling mill. In order to prevent the shaft parts from deviating when rolling, limit baffles 9 are provided on both sides of the inclined plane. The limit baffles 9 can play a restraining role when the shaft parts roll.

[0024] Furthermore, during use, some oxide scale may fall onto the inclined surface but fail to enter the collection port 14. To ensure this oxide scale can smoothly enter the collection port 14, an auxiliary cleaning mechanism is provided between the two limiting baffles 9. The auxiliary cleaning mechanism includes a mounting plate 11 and a brush 17 fixed on the mounting plate 11, with the brush 17 in contact with the inclined surface. A linear slide rail 10 is installed on the inner side of each limiting baffle 9, and the linear slide rail 10 is arranged along the length of the limiting baffle 9. A slider 16 is installed on each linear slide rail 10, and the two ends of the mounting plate 11 are connected to two sliders 16 respectively. When the mounting plate 11 is held by hand and slids along the linear slide rail 10, the brush 17 can sweep the oxide scale stuck on the inclined surface into the collection port 14.

[0025] In order not to affect the rolling of shaft parts, when cleaning is not required, the brush 17 is located at the higher end of the inclined plane. In order to position the brush 17, a positioning bolt 13 for tightening the inclined plane is threaded onto the mounting plate 11. The positioning bolt 13 is used to tighten the inclined plane to achieve the positioning of the brush 17.

[0026] In this embodiment, a handrail 12 is installed on the top surface of the mounting plate 11 to facilitate the movement of the mounting plate 11.

[0027] In this embodiment, to prevent the cut material from falling into the collection box 6, an intercepting net 15 is installed at each collection port 14.

[0028] In this embodiment, ear plates 8 are provided on both sides of the bottom surface of the collection box 6, and each ear plate 8 is connected to the panel 4 by bolts.

[0029] In actual use, when the wedge cross rolling mill is running, the industrial vacuum cleaner is turned on. The rolled shaft parts will fall onto the inclined surface and roll along the inclined surface to one side of the wedge cross rolling mill. The fallen oxide scale is collected and processed by the oxide scale cleaning device.

[0030] This application utilizes the height difference between the lower roller 3 and the panel 4, and uses this height difference to add an oxide scale cleaning device between them. By using the oxide scale cleaning device in conjunction with the auxiliary cleaning mechanism, oxide scale cleaning can be easily achieved.
