Description

Technical Field

[0001] This utility model belongs to the technical field of stainless steel polishing equipment, and in particular relates to a belt polishing device for stainless steel surface treatment of embedded parts. Background Technology

[0002] Belt polishing machines utilize belt grinding technology to process workpieces. With the development of adhesives, the emergence of water- and oil-resistant all-resin high-strength abrasive belts has significantly improved the grinding performance of abrasive belts.

[0003] The difference between abrasive belts and grinding wheels when machining workpiece surfaces is that grinding wheels are under tensile stress during grinding, and due to heat accumulation, they are prone to micro-cracks and burns on the workpiece surface during grinding; while abrasive belts have the dual function of grinding and polishing, are under compressive stress, generate less heat, and are less prone to burns, hence the name cold grinding, and their cutting performance is significantly higher than that of ordinary grinding wheels. Utility Model Content

[0004] The purpose of this invention is to provide a belt polishing device for the surface treatment of embedded stainless steel parts, thereby improving the polishing efficiency and quality of embedded stainless steel parts.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A belt polishing device for stainless steel surface treatment of embedded parts includes a main beam. The bottom of the rear end of the main beam is supported by a rear wheel. A traction rod is fixed at the front end of the main beam. A drive roller, a pressing roller and a transition roller are distributed at three points on the upper side of the main beam. The drive roller, the pressing roller and the transition roller are connected by an annular sand belt. The sand belt is triangular after being connected.

[0007] The main beam is equipped with a motor for rotating drive rollers, the pressing rollers are fixed to the front end of the main beam, and the transition rollers are supported by a support frame.

[0008] The front end of the main beam is also equipped with casters, which provide support for the front end of the main beam. The casters are installed on the front end of the main beam through elastic components.

[0009] Furthermore, the caster wheel is mounted on a diagonal brace, and a horizontal brace is provided above the diagonal brace. A mounting plate is provided at the same end of the diagonal brace and the horizontal brace. The end of the horizontal brace is fixed to the mounting plate, and the end of the diagonal brace is hinged to the mounting plate. The caster wheel is mounted on the free end of the diagonal brace, and the free end of the diagonal brace and the free end of the horizontal brace are supported by an elastic component.

[0010] The elastic component is a spring, the universal wheel has a pivot, the pivot passes through the lower end of the diagonal support frame and is rotatably engaged, the pivot corresponding to the part of the diagonal support frame that passes through is used for positioning the lower end of the spring, and the upper end of the cross support frame is fixed with a positioning rod for positioning the upper end of the spring.

[0011] Furthermore, a rubber ring is fitted onto the surface of the pressing roller, and the surface of the rubber ring has gear-shaped stripes.

[0012] The present invention has the following beneficial effects: The improved belt polishing machine has been used in the processing of embedded stainless steel in multiple projects. The improved belt polishing machine has a very good polishing effect, which greatly improves the polishing efficiency and polishing quality of embedded stainless steel. At the same time, compared with wheel polishing, the flatness of the embedded stainless steel surface after belt polishing is also greatly improved.

[0013] The improved belt polishing machine generates less frictional heat when machining embedded stainless steel parts, and the long time interval between abrasive grain heat dissipation effectively reduces workpiece deformation and burns. Because the belt grinding involves flexible contact with the workpiece, it provides better running-in and polishing effects. The belt grinding equipment has a simple structure, low manufacturing cost, and minimal wear on the contact wheel, allowing the belt to maintain a constant speed. The transmission chain is short, and auxiliary time is reduced. After the workpiece is clamped and positioned once, the belt can be changed multiple times to complete the entire machining process, eliminating the need for balancing and dressing work required for grinding wheels.

[0014] Belt polishing machines are easy to operate and improve the polishing quality of stainless steel embedded parts. The surface roughness of the workpiece can reach Ra0.8~0.2μm. Through equipment improvement, the polishing efficiency is high, which is 5 to 20 times that of ordinary abrasive wheel polishing. Belt polishing is very safe. The abrasive belt itself is very light and there is no risk of injury even if it breaks.

[0015] Unlike grinding wheels, belt polishing does not produce as much abrasive residue, especially during dry grinding. The abrasive chips mainly consist of the material of the workpiece being processed, making dust recovery and control easy. Because it uses rubber contact wheels, belt polishing does not create a rigid impact on the workpiece like grinding wheels, resulting in very low processing noise, typically around £70dB, and good environmental benefits.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1-2 The device, shown, is a belt polishing apparatus for stainless steel surface treatment of embedded parts. It includes a main beam 1, with two rear wheels 11 supporting the bottom of the rear end of the main beam 1, distributed left and right to improve stability. A traction rod 12 is fixed to the front end of the main beam 1 for hand-held dragging. The main beam is dragged by the traction rod, coordinating with the movement of the rear wheels. A drive roller 2, a pressing roller 3, and a transition roller 4 are distributed at three points on the upper side of the main beam 1. These rollers are connected by an annular sanding belt 6, forming a triangular structure. The pressing roller, transition roller, and drive roller are all located on the side of the main beam. When the main beam moves along the side of the steel component, the corresponding sanding belt is directly above the steel component. The pressing roller is located at the lowest position of the three rollers. When it contacts the surface of the steel component, it facilitates the hand-held traction rod to apply force to the pressing roller, causing the sanding belt on the pressing roller to contact the surface of the steel component, thus achieving the polishing process.

[0023] A motor 21 for rotating drive roller 2 is installed on the upper side of the main beam 1. The roller shaft corresponding to the pressing roller 3 is fixed to the front end of the main beam 1. The roller shaft corresponding to the transition roller 4 is raised by the support frame 13. The upper side of the main beam also has a support plate for installing the motor and the support frame.

[0024] The front end of the main beam 1 is also equipped with casters 5, which provide support for the front end of the main beam 1. The casters 5 are installed at the front end of the main beam 1 through elastic components.

[0025] The main beam has a caster wheel at the front and two rear wheels at the rear. The caster wheel facilitates steering and, together with the rear wheels, forms a movable polishing trolley. There is an elastic component between the caster wheel and the main beam. When polishing steel components, the hand-held traction rod is moved along the surface of the steel component to be treated. At the same time, the traction rod can be pressed to compress the elastic component, changing the force of the pressure roller contacting the surface of the steel component. For local thick rust layers, the polishing time and pressure can be increased to make the polishing more thorough.

[0026] like Figure 3As shown: A caster wheel 5 is mounted on a diagonal support frame 71. A cross support frame 72 is located above the diagonal support frame 71. A mounting plate 7 is provided at the same end of both the diagonal support frame 71 and the cross support frame 72. The end of the cross support frame 72 is fixed to the mounting plate 7. The end of the diagonal support frame 71 is hinged to the mounting plate 7. The caster wheel 5 is mounted on the free end of the diagonal support frame 71. The free ends of the diagonal support frame 71 and the cross support frame 72 are supported by an elastic component. The diagonal support frame has an inclined portion and a horizontal portion, with the horizontal portion parallel to the cross support frame. When the caster wheel is pressed, the elastic component can deform, providing sufficient downward movement space for the pressing roller.

[0027] The elastic component is a spring 8, and the caster wheel 5 has a pivot 51. The pivot 51 passes through the lower end of the diagonal brace 71 and is rotatably engaged. The portion of the pivot 51 that passes through the diagonal brace 71 is used for positioning the lower end of the spring 8. A positioning rod 73 is fixed to the upper end of the cross brace 72 for positioning the upper end of the spring 8. The caster wheel is installed at the lower end of the pivot. The multi-directional adjustment of the caster wheel is achieved through the rotational engagement between the pivot and the lower end of the diagonal brace. The spring is a tubular spring, and its end is fixed through the protruding part of the pivot and the positioning rod. When the caster wheel is pressed, the spring not only compresses and deforms, but also deforms in an arc shape to meet the arc-shaped movement trajectory of the diagonal brace in its arc-shaped hinged state.

[0028] like Figure 1 As shown: A rubber ring 31 is fitted onto the surface of the pressure roller 3, and the surface of the rubber ring 31 has gear-shaped stripes. This increases the friction between the pressure roller and the sanding belt, and facilitates the removal of localized residue on the sanding side of the sanding belt when grinding and polishing steel components.

[0029] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
