Description

Technical Field

[0001] This utility model relates to a grinding wheel extrusion molding device, and more particularly to a grinding wheel extrusion molding device that is easy to process and replace the rolling rollers. Background Technology

[0002] Many grinding wheels, after sintering, require extrusion to create precise patterns on their outer circumference. For example, brittle bonded grinding wheels such as corundum or ceramic-bonded diamond grinding wheels, after sintering, are mounted on a machine tool spindle. A rotatable roller with corresponding patterns is installed below the grinding wheel. As the spindle rotates, the grinding wheel and roller contact and compress each other. Under the combined action of the grinding wheel and the roller, excess material on the outer circumference of the grinding wheel is compressed into powder and separated, forming patterns consistent with those on the roller. After multiple cycles of rolling, the final grinding wheel has precise patterns on its outer circumference. The roller and its mounting structure constitute a grinding wheel extrusion forming device, working in conjunction with a machine tool to achieve the pressure forming process of the grinding wheel.

[0003] like Figure 1 As shown, a traditional grinding wheel extrusion molding device includes a traditional rolling wheel 3, a mandrel 4, and a mandrel mounting base 2. The traditional rolling wheel 3 has a textured outer circumference and a central through hole through which the mandrel 4 passes. The traditional rolling wheel 3 can rotate relative to the mandrel 4. Both ends of the mandrel 4 are mounted on the mandrel mounting base 2. In use, the grinding wheel 1 to be extruded is mounted on the machine tool spindle (not shown in the figure). The grinding wheel 1 is pressed down on the traditional rolling wheel 3 from top to bottom and driven to rotate. Under the action of the grinding wheel 1 driving the traditional rolling wheel 3 to rotate and extrude each other, the excess part on the outer circumference of the grinding wheel 1 is extruded into powder and separated, forming a texture consistent with that of the traditional rolling wheel 3. After multiple cycles of rolling, the final grinding wheel 1 has a precise texture on its outer circumference.

[0004] The aforementioned traditional grinding wheel extrusion molding device has the following drawbacks: To ensure the rolling effect, the central through hole of the traditional rolling wheel 3 and the mandrel 4 need to be precisely matched to produce a high-precision grinding wheel 1. The central through hole of the traditional rolling wheel 3 and the mandrel 4 both need to be precisely ground. After high-precision grinding, they still need to be carefully hand-ground to achieve a dynamic fit effect with almost zero clearance. This is because the structure between the traditional rolling wheel 3 and the mandrel 4 is equivalent to that of a sliding bearing. It is very difficult to achieve such high precision in a sliding bearing. Therefore, this is a very difficult process with extremely low production efficiency. At the same time, each time the traditional rolling wheel 3 is replaced, the mandrel 4 and the mandrel mounting seat 2 need to be disassembled and reassembled, which is cumbersome and reduces production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a grinding wheel extrusion molding device that facilitates the processing and replacement of the rolling rollers in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A grinding wheel extrusion molding device that facilitates the processing and replacement of rolling rollers includes rolling rollers, guide rollers, and guide roller mounting seats. Each guide roller includes a cylindrical support shaft with guide cylinders of larger outer diameters located near both ends of the transverse support shaft. The centerlines of the guide cylinders coincide with the centerline of the support shaft. Both ends of the support shaft are connected to the corresponding guide roller mounting seats via rolling bearings. The support shafts of the two guide rollers are parallel and flush at both ends. The guide cylinders of the two guide rollers are close to each other and at the same height. Each rolling roller includes a cylindrical forming shaft with forming patterns on its outer circumference. Rolling cylinders of larger outer diameters are located at both ends of the transverse forming shaft. The centerlines of the rolling cylinders coincide with the centerline of the forming shaft. The rolling roller is located above the two guide rollers, and each rolling cylinder contacts the two guide cylinders at the same end.

[0008] Preferably, in order to limit the axial ends of the rolling roller and facilitate the adjustment of the limiting distance, the grinding wheel extrusion molding device for easy processing and replacement of the rolling roller also includes limiting bolts. The two limiting bolts are respectively installed on the guide wheel mounting seat and are respectively located on the axial outer side of the two rolling cylinders.

[0009] Preferably, in order to facilitate processing and assembly and to facilitate the installation of the limiting bolts, the guide wheel mounting base includes four, with each end of the support shaft of the guide wheel connected to two guide wheel mounting bases respectively, and the two guide wheel mounting bases at the same end connected above by a mounting base pressure plate, and the two limiting bolts respectively mounted on the two mounting base pressure plates.

[0010] Preferably, in order to improve the stability of the entire device, the grinding wheel extrusion molding device that facilitates the processing and replacement of the rolling rollers also includes a base plate, and a plurality of the guide wheel mounting seats are respectively mounted on the base plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention features guide cylinders positioned near both ends of a guide wheel and mounted on a guide wheel mounting base via rolling bearings. The two guide wheels are arranged in parallel, and rolling cylinders are positioned at both ends of the rolling wheel. The rolling wheel is placed above the two guide wheels, allowing it to rotate with high precision without centerline deviation, thanks to the cooperation of the two guide wheels. The rolling wheel no longer requires a high-precision machined center through-hole; instead, the installation accuracy is ensured primarily by the machining accuracy of its outer circumference and the rolling bearings. Since the machining accuracy of the outer circumference of the cylinders and the rolling bearings are easily achievable with existing technology, the machining accuracy of this invention is guaranteed, and the process is simple and quick, improving the production efficiency of the device. The "V"-shaped support structure formed by the two guide wheels provides stable and reliable support for the rolling wheel, offering higher support strength and allowing for greater pressure on the rolling wheel, thus improving the quality and efficiency of the rolling process. Furthermore, since the rolling wheel is directly placed on the two guide wheels, replacing the rolling wheel does not require disassembly of any components, significantly improving the efficiency of rolling wheel replacement and making it more convenient to use.

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figure 2As shown, the abrasive wheel extrusion molding device of this utility model, which facilitates processing and replacement of rolling rollers, includes a rolling roller, a guide wheel, and a guide wheel mounting base 6. The guide wheel includes a cylindrical support shaft 11. A guide cylinder 9 with a larger outer diameter is provided near both ends of the transverse support shaft 11. The center line of the guide cylinder 9 coincides with the center line of the support shaft 11. Both ends of the support shaft 11 are connected to the corresponding guide wheel mounting base 6 via rolling bearings (not visible in the figure). The support shafts 11 of the two guide wheels are parallel to each other and flush at both ends. The guide cylinders 9 of the two guide wheels are close to each other and at the same height. The rolling roller includes a cylindrical forming shaft 12 with forming patterns on its outer circumference. A rolling cylinder 10 with a larger outer diameter is provided at both ends of the transverse forming shaft 12. The center line of the rolling cylinder 10 coincides with the center line of the forming shaft 12. The rolling roller is located above the two guide wheels, and each rolling cylinder 10 is in contact with the two guide cylinders 9 at the same end.

[0018] like Figure 2 As shown, this utility model also discloses the following more optimized specific structures:

[0019] In order to limit the axial ends of the rolling roller and facilitate the adjustment of the limiting distance, the grinding wheel extrusion molding device for easy processing and replacement of the rolling roller also includes limiting bolts 8. The two limiting bolts 8 are respectively installed on the guide wheel mounting seat 6 and are respectively located on the axial outer side of the two rolling cylinders 10.

[0020] To facilitate processing and assembly and to facilitate the installation of the limiting bolts 8, the guide wheel mounting base 6 includes four. The two ends of the support shaft 11 of each guide wheel are respectively connected to two guide wheel mounting bases 6. The two guide wheel mounting bases 6 at the same end are connected above by a mounting base pressure plate 7.

[0022] like Figure 3As shown, in use, the workpiece 13 (i.e., the grinding wheel whose circumferential surface has not yet been rolled) is first installed on the machine tool spindle (not shown in the figure). The workpiece 13 is pressed down on the forming shaft 12 of the rolling wheel from top to bottom. The machine tool drives the workpiece 13 to rotate, and the workpiece 13 drives the rolling wheel to rotate accordingly. The rolling wheel drives two guide wheels to rotate through two rolling cylinders 10 and four guide cylinders 9. The two guide wheels rotate in the same direction and opposite to the rotation direction of the rolling wheel. Under the action of mutual rotation and extrusion between the workpiece 13 and the rolling wheel, the excess part on the outer circumference of the workpiece 13 is extruded into powder and separated, forming a texture consistent with the forming shaft 12 of the rolling wheel. After multiple cycles of rolling, the grinding wheel extrusion forming process is completed.
