Description

Automatic cleaning device of burr machine waste material
Technical Field
The invention relates to the technical field of deburring machines, in particular to an automatic waste cleaning device of a deburring machine.
Background
After the sector is punched, each punching sheet needs to be subjected to strict deburring, burrs in the punching process are controlled in a minimum range, continuous deburring is generally carried out twice abroad, two deburring machines are connected on line in an automatic punching sheet production line, the deburring machine is of a roller grinding wheel type and a sand belt type, and the latter is mainly characterized in that: the abrasive belt has the advantages that the rotating speed is high and can reach 10-35 m/min, the abrasive belt is simple, convenient and quick to replace and can adapt to punching sheets with various shapes and thicknesses, the abrasive belt is better in deburring quality than a roller type abrasive wheel, the abrasive belt is coated on a rubber belt which rotates at a high speed and is provided with a spiral groove, the abrasive belt can be prevented from being polluted by the groove, the pressure of the abrasive belt is controlled by compressed air, the constant pressure is kept, and the vehicle can be automatically stopped when the abrasive belt is damaged or other faults occur. The deburring machine needs to be debugged firstly, the machine is started firstly during debugging, a workpiece is placed into the polishing barrel from less to more, the number and the weight of the workpiece and the body type of the workpiece have a reaching relation, so that the workpiece is slowly placed into the polishing barrel to be increased, the rotation of the workpiece is slowed down, but the workpiece cannot be stationary, when the workpiece is stationary and rotated, the polished product liquid is not uniform, and the polishing time is unnecessarily prolonged. Before polishing, the surface of a workpiece must be cleaned up, a polishing solution cannot remove a large amount of oil dirt, otherwise the workpiece, a polishing needle, water and a polishing barrel are likely to be blackened, the deburring effect is influenced due to slipping, and cleaning solution must be used and dried when the polishing needle and the polishing barrel are cleaned up.
The two functions of removing the burrs on the billets are respectively to improve the rolling quality of the billets and reduce the damage to a conveying roller and a rolling roller. After the slab is formed by a continuous casting machine, the slab is cut according to a fixed length, and then is transmitted to a burr removing machine by a transmission roller way, and enters a deburring village for opening the cutting process. The plunger cross beam of the deburring machine in the initial state of the deburring machine is at the lowest position, the blade is retracted, the upper edge of the blade is positioned below the upper edge of the Korean channel, when blanks are conveyed to the grating, the blank traveling speed is reduced to the deburring speed from the conveying speed, the blank conveying is stopped by the deburring speed, the blade and the plunger cross beam ascend simultaneously, the blade is pressed on the lower surface of the blanks, the blanks move rightwards by the deburring speed to complete the deburring action, when the blanks move to the grating, the blade and the plunger cross beam descend simultaneously, the blank conveying is stopped, and the plunger cross beam overturns 90 degrees to complete the cleaning program. Then the blank moves leftwards at the conveying speed, and enters a procedure of removing burrs at the tail part of the blank, and the tail part burr removing process is the same as the above.
But at present there is not the automatic cleaning device of waste material that is used for on this burr-grinding machine specially, if do not clear up the burr for a long time, can influence burr-grinding machine normal use, the indiscriminate flight of burr also can cause the injury to the people.
