[0001] The utility model relates to the technical field of punching machines, in particular to a punching machine for processing elastic fiber grinding discs. Background Art

[0002] Elastic fiber abrasive discs are tools with soft and elastic properties used for grinding and polishing. They are usually composed of adhesives and abrasive particles, and adopt a special manufacturing process to form soft and flexible grinding and polishing tools. When processing elastic fiber abrasive discs, an elastic fiber abrasive disc punching machine is needed to punch and cut the elastic fiber abrasive discs to complete the processing of specific shapes and sizes. Existing punching machines usually use cutting tools of special shapes for punching during the processing. Since the elastic fiber abrasive discs have a certain elasticity, it is difficult for specific cutting tools to assist in positioning the processing materials, resulting in warping of the edges when the abrasive discs are punched, making it impossible for the shape and size of the abrasive discs to meet the predetermined requirements, while affecting the smoothness of the punched area of ​​the abrasive discs and reducing the overall punching accuracy and quality. Therefore, we propose a punching machine for processing elastic fiber abrasive discs to solve the above-mentioned problems. Utility Model Content

[0025] When working, first insert the elastic fiber grinding disc material to be processed between the roller 203 and the auxiliary wheel 204, start the two sets of driving motors 202 to drive the rollers 203 at both ends to rotate along the inside of the connecting frame 201, so that the rollers 203 and the auxiliary wheels 204 clamp the conveyed material to ensure that the material is clamped and conveyed at a certain speed and strength, and realize accurate control of the conveyed material to adapt to elastic fiber grinding discs of different types and thicknesses. When the material is stably transmitted along the upper end of the load-bearing plate 205, it effectively prevents the grinding disc from shifting during the transmission process, keeps the grinding disc flat and stable, and then presses the According to the preset working time of the driving motor 202, the material is stably transmitted to the bottom of the punching die 306 and then stops running. When the driving motor 202 stops running, the hydraulic cylinder 302 is automatically turned on to drive the hydraulic rod to run, and the hydraulic rod is used to drive the driving rod 303 to operate back and forth. The driving rod 303 fixes multiple groups of connecting rods 304 and combines with the positioning plate 305 to drive the punching mold for punching. The two groups of hydraulic cylinders 302 ensure that the punching force is strong enough to punch the elastic fiber grinding disc.

[0026] The positioning plate 305 is used to connect multiple sets of punching dies 306 to punch the material on the upper end of the auxiliary plate 310. Before the punching die 306 punches the material, the pressure plates 308 at both ends of the positioning plate 305 are combined with the internal springs 309 of the sleeve plate 307 to preferentially contact the material for rebound positioning, so as to keep the material flat and stable during the punching process and reduce the punching error caused by shaking and vibration during the processing. Secondly, the auxiliary plate 310 assists the punching die 306 in punching, so that the positioning plate 305 and the auxiliary plate 310 clamp the material relatively and keep a fixed position during the punching process, so as to reduce the vibration and shaking during the punching process and ensure that the punching die 306 is stable.

At the same time, after a single punching of the material, the driving motor 202 is started again according to the preset stop time to transfer the required punching material to realize continuous and stable punching of the material. During the second transmission of the material, the elastic fiber grinding disc pushes the punched material to the inclined plate 311, and the inclined plate 311 falls into the collection rack 403 for collection, so as to stably process the elastic fiber grinding disc.

Two sets of hydraulic cylinders 302 are used to drive the hydraulic rod to connect the driving rod 303 to drive the mold for punching, ensuring that the punching force is strong enough to punch the elastic fiber grinding disc. The size of the punching force and the speed of the punching are adjusted as needed to cope with the reciprocating punching of various materials.
