Description

Grinding device for metal processing

Technical Field

The invention belongs to the technical field of metal grinding, and in particular relates to a grinding device for metal processing.

Background technique

Metal workpiece processing is an important process in the mechanical processing industry. The existing processing procedures include grinding, polishing, and polishing. Among them, grinding is the most basic and important part. Grinding refers to the processing method of using abrasives and grinding tools to remove excess materials on the workpiece. Grinding is one of the most widely used cutting methods. It uses high-speed rotating grinding wheels and other grinding tools to process the surface of the workpiece.

At present, in the process of metal grinding, the metal debris generated is easy to splash onto the protective cover and rebound onto the workpiece, which is easy to cause scratches on the workpiece. At the same time, due to the rebound of metal debris, it may be stuck between the moving parts of the processing equipment, causing jamming or wear, affecting the use effect and service life of the processing equipment. In addition, the repeated rebound and collision of metal debris are prone to produce abnormal noise, resulting in large noise pollution of the environment. At the same time, the sparks and waste generated by metal grinding are splashed everywhere, which not only pollutes the workbench, but also produces high-temperature sparks.

In the present embodiment: when the grinding device for metal processing is used, the workpiece to be processed is first placed on the clamp 3 for clamping and fixing, and then the workpiece is ground by the grinding wheel mechanism 2. During the grinding process, the metal debris and sparks generated are splashed in one direction. The protective seat 401, the baffle plate 413 and the elastic leather 414 are used in combination to protect and avoid the large amount of metal debris and sparks from splashing outward, thereby not affecting the operation of the staff. During the grinding process, the drive motor 402 is started at the same time, which drives the rotating shaft 403 to rotate. As the rotating shaft 403 rotates, it also drives the bevel gear mechanism 404 to rotate, and by driving the rotating rod 405 to rotate, it drives the multiple sets of fan plates 406 to rotate synchronously. When the metal debris contacts When the EPE plate 410 is used, since the EPE plate 410 has a good energy absorption effect, it can reduce the collision and reduce the rebound force. When the metal debris rebounds slightly, with the rotation of the multiple sets of fan plates 406, the other set of fan plates 406 can play a certain local shielding role. At the same time, the splashed iron metal debris can be magnetically adsorbed by the magnet plate 409 itself, which further prevents the metal debris from rebounding. This structure can effectively prevent the metal debris from rebounding onto the workpiece again during the splashing process, thereby avoiding scratches on the workpiece, and preventing the metal debris from getting stuck between the moving parts of the processing equipment and causing jamming or wear, thereby improving the use effect and service life of the processing equipment, and avoiding abnormal noise caused by multiple rebound collisions, avoiding large noise pollution to the environment, and at the same time, the metal With the cooperation of the rotation of the multiple sets of fan plates 406 and the arc groove 412, some of the debris can be moved into the collection cover 411. At the same time, some of the debris adsorbed by the magnet plate 409, when in contact with the scraper 424, is scraped by the scraper 424 into the collection cover 411 for collection, so that the workbench will not be contaminated by the debris splashing everywhere, the cleaning of the staff is reduced, the labor intensity of the staff is reduced, and the actual use needs are met. When the fan plate 406 contacts the scraper 424, the fan plate 406 will produce a certain angle while the scraper 424 blocks it, and drive the spring 408 to perform elastic deformation until the fan plate 406 passes over the scraper 424. During the movement of the grinding wheel mechanism 2, the roller 418 moves on the inclined plate 419. The surface slides, and when the grinding wheel mechanism 2 moves longitudinally, the roller 418 drives the connecting rod 415 to slide on the limit rod 1 416, so that the connecting rod 415 can slide synchronously on the baffle plate 413, and the connecting rod 415 compresses the spring 2 417. In this process, the rebound of the spring 2 417 can make the connecting rod 415 and the grinding wheel mechanism 2 always fit tightly. When the grinding wheel mechanism 2 moves horizontally, the baffle plate 413 is driven to rotate by the connecting rod 415. Through this operation, the baffle plate 413 and the elastic leather 414 can change their shape synchronously with the grinding wheel mechanism 2, thereby further improving the protection effect, better avoiding the splashing of sparks and waste, and avoiding the great safety hazards caused by the high-temperature sparks, thereby improving the use effect of the device.

As the rotating shaft 403 rotates, the reciprocating screw rod 501 is driven to rotate. Since the reciprocating screw rod 501 and the movable plate 502 are threadedly connected, the movable plate 502 is driven to move. Through the movement of the movable plate 502, the push rod 503 is driven to move. The push rod 503 drives two groups of movable pistons 505 to slide inside the air supply hood 1 504 and the air supply hood 2 508 respectively. As the movable piston 505 moves, the gas inside the air supply hood 1 504 can be compressed to the exhaust pipe, so that the exhaust pipe is discharged through the bamboo tube 1 507. The exhausted gas can blow metal debris to the position of the fan plate 406, which can enable the fan plate 406 to better handle the metal debris and avoid contact between the metal debris and the workpiece to cause scratches. At the same time, the processing accuracy and speed are guaranteed, the wear of the debris on the tool is reduced, the production interruption caused by tool damage is reduced, the risk of injury caused by debris splashing is prevented, and the working area is kept clean.

As the movable plate 502 moves, when the movable plate 502 moves to a certain position and contacts the touch switch 610, the touch switch 610 controls the start of the pump 602, thereby extracting the grinding liquid inside the liquid storage tank 601 and transporting it to the inside of the discharge pipe 603. The discharge pipe 603 is discharged through the bamboo joint tube 604. Since the bamboo joint tube 604 can be folded freely, it can be flexibly directed at different angles for different workpieces. The grinding liquid discharged through the bamboo joint tube 604 is discharged onto the workpiece, thereby facilitating the removal of surface stains, defects and oxides to improve the quality and smoothness of the metal surface. At the same time, it can also adjust the surface roughness to meet different needs, and quickly remove burrs and other undesirable phenomena on the material surface during processing, which helps to improve the processing efficiency of the workpiece. At the same time, it can realize intermittent liquid discharge operation. By discharging the grinding fluid intermittently, the grinding fluid can be used more effectively to avoid excessive consumption. This method can reduce production costs, improve resource utilization, and avoid the accumulation of grinding fluid, keep the working environment clean, and help improve the work efficiency and safety of workers.

By moving the sleeve 605 and driving the spring four 606 to stretch or compress, the touch switch 610 is driven to move, and at the same time, the threaded rod 607 is rotated to drive the block 609 to move until the block 609 fits with the surface of the second mounting block, so that the position of the sleeve 605 can be limited, so that the position of the touch switch 610 can be flexibly adjusted, so that the moving plate 502 and the touch switch 610 can be in contact for different time periods, and the drainage time periods can be indirectly different. This structure is more flexible and practical, so that different amounts of grinding liquid are used for workpieces of different sizes.

When it is necessary to clean the metal debris inside the collecting cover 411, the shell 420 is moved to drive the fixed plate 421 to slide on the limit rod 2 422, and the spring 3 423 is squeezed to compress until the shell 420 releases the blockage of the collecting cover 411, and then the collecting cover 411 can be taken out from the protective seat 401. When one end of the collecting cover 411 is pulled out of the protective seat 401, the shell 420 is then released, so that the shell 420 is inside the collecting cover 411. As the collecting cover 411 is pulled, the metal debris inside the collecting cover 411 can be flattened to prevent the metal debris on the top from overflowing. Through this structure, the use effect of the device can be better improved to meet actual use needs.

It should be noted that: a one-way air inlet valve is installed on one side of the air supply hood 1 504 and the air supply hood 2 508, and a one-way exhaust valve is installed at one end of the exhaust pipe.

Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
