Description

Technical Field

[0001] The invention relates to a wide-band sanding machine and a heavy-duty roller adjustment method, which can adjust the lower roller of the wide-band sanding machine horizontally during processing to adapt to the titanium and titanium alloy plates in a flared state in the width direction. The wide-band sanding machine is mainly used for sanding and grinding titanium and titanium alloy plates, and belongs to the field of wide-band sanding machine manufacturing. Background Art

[0002] With the surge in demand for titanium and titanium alloy plates in the fields of aerospace, chemical energy, military equipment, etc. at home and abroad in recent years, domestic enterprises have entered the stage of capacity expansion, and equipment has also become large-scale with the development of technology. Taking the rolling mill for rolling titanium alloy thin plates as an example, the newly introduced equipment of the leading scale enterprises can roll plates with a width of 1600mm, and more advanced equipment can even roll plates with a width of 2200mm. With the large-scale width of the rolled plates, the relative parallelism of the grinding roller and the lower roller in the existing titanium and titanium alloy plate sanding process is particularly important. Due to the equipment level of the rolling mill and the rolling process, the rolled plates are inevitably large in difference, especially in the width direction, and the microscopic state is the plate in the flare state in the width direction. In order to deal with the rolling flare defects in the width direction of the plate, the grinding roller and the lower roller of the sanding process also need to be adjustable to cope with the processing of this type of plate. Summary of the invention

[0003] Design purpose: To avoid the shortcomings of the background technology, a method is designed to horizontally adjust the lower roller of a wide-band sander during processing to adapt to the wide-band sander with adjustable heavy-duty rollers for titanium and titanium alloy plates in a flared state in the width direction.

[0004] Design scheme: In order to achieve the above design objectives. The present invention is designed in terms of scheme: Based on the existing background technology, the heavy-duty lower roller in the wide belt sander is designed to be adjustable. The entire mechanism includes a lower roller, front and rear bearing seats, a lower frame (frame), a lift, an adjustment handle, and an adjustment scale diagram.

[0005] The heavy roller is adjusted by the adjustment handle 11, which is installed on the transition shaft 9. The transition shaft 9 is connected to the elevator input shaft through the coupling 8. In order to enhance the strength, the transition shaft 9 is installed on the frame through the seat bearing 10 (see Figure 5). The output flange of the elevator is fixed to the front bearing seat, the elevator is fixed on the lower frame, and the rear bearing seat is also fixed to the lower frame. When the lower roller needs to be adjusted horizontally, turn the handle in the specified direction. The lower roller uses the self-aligning bearing in the rear bearing seat as a fulcrum and rises or falls in the specified direction through the screw inside the elevator. The size of the bell mouth is determined according to the adjustment schematic scale. The matching formula for the relationship between the schematic scale and the bell mouth angle is H=2078*tan(α)H is in millimeters (mm), and α is in degrees, so as to achieve the purpose of adjusting the level of the lower roller. (See Figure 6 ) Technical Solution 1: A wide-band sander with adjustable heavy-duty rollers, comprising a wide-band sander, a rear-end bearing seat being installed on the frame of the wide-band sander and a front-end bearing seat being installed on the elevator, two ends of the lower roller in the wide-band sander being respectively installed on the front-end bearing seat and the rear-end bearing seat, an adjusting handle being connected to the elevator input shaft, and the relative angle of the lower roller can be adjusted by rotating the adjusting handle left and right.

[0006] Technical Solution 2: A method for a wide-band sanding machine with adjustable heavy-duty rollers, comprising a wide-band sanding machine, an elevator and a rear-end bearing seat respectively fixed on a lower frame, the adjustable heavy-duty rollers of the wide-band sanding machine are adjusted by an adjusting handle, the adjusting handle drives the input shaft of the elevator, and the output flange of the elevator is fixed to the front-end bearing seat (supplementary figure), when it is necessary to adjust the level of the lower roller, the handle is turned in a specified direction, the lower roller uses the self-aligning bearing in the rear-end bearing seat as a fulcrum, and rises or falls in a specified direction through the screw inside the elevator, the size of the bell mouth is determined according to the adjustment schematic scale, and the relationship between the schematic scale and the bell mouth angle is matched by a formula of H=2078*tan(α), where H is in millimeters (mm) and α is in degrees, thereby achieving the purpose of adjusting the level of the lower roller.

[0007] Compared with the background technology, the present invention can, firstly, adapt to the sanding process requirements of titanium and titanium alloys with different rolling tolerances, thereby expanding the processing range of the wide-band sander; secondly, through adjustment, the sanding of the entire plate can avoid the disadvantage that the high points must be ground off to complete the grinding of the entire plate surface, and can be adjusted along the flare of the plate surface. The plate surface can be ground off with a slight inclination, thereby greatly improving the production efficiency of the sanding process and reducing the plate loss in the sanding process. Under the same conditions, less material ground off can also greatly reduce the waste in the processing process. BRIEF DESCRIPTION OF THE DRAWINGS
