Description

Blade cylinder device suitable for slab deburring machine
Technical Field
The invention relates to steel plate surface deburring machine equipment, in particular to a blade cylinder device suitable for a slab deburring machine.
Background
The deburring device used in the wire board processing area of the iron and steel enterprise is generally arranged at the rear path of an automatic flame cutting machine, is used for removing slag burrs generated on the lower surface of a plate blank when a long plate blank conveyed to a thick plate by continuous casting is changed into 2 or 3 sub-blanks after automatic flame cutting, is also arranged on a charging roller way of a heating furnace, and is used for removing steel plate slag at the notch of the lower surface of the plate blank after part of the steel plate blank is manually cut.
During the field use, the problems that often appear are mainly:
1. when burrs at the head edge and the tail edge of a plate blank are removed by a cutting edge of the deburring machine, the cutting edge is influenced by the reaction force of the plate blank to generate a turnover moment, 3 hexagon socket head cap bolts fixed by the cutting edge are sheared and broken under the action of frequent alternating turnover moment, the cutting edge flies out in the deburring process, and meanwhile, the cutting edge is unstable because threaded holes in a piston rod are damaged due to frequent breakage of the bolts, and the cutting edge can be installed again when the machine is stopped and the piston rod is replaced;
2. the cylinder gland is impacted positively and negatively by the piston rod, the fixing bolt is sheared and broken, the cylinder leaks air after the cylinder gland is jacked up, and the air pressure of compressed air of the deburring machine is reduced, so that the piston rod is not lifted in place;
3. the piston rod is provided with 1 guide sleeve made of composite carbon fiber, a pneumatic component generates a dry friction phenomenon in the reciprocating process due to the fact that a cylinder adopts compressed air as a medium, the self-lubricating performance of the guide sleeve is required to be superior, carbon fibers are good in lubricating performance, but a deburring machine is large in impact vibration in the using process, the material is prone to brittle fracture under the impact working condition, the gap between the piston rod and a bush is enlarged, the piston rod deflects in the deburring process, the piston rod is often bent under the transverse reaction force of a plate blank, the piston rod is finally blocked up and down or is pressed against a cylinder end cover to cause the breakage of an end cover bolt, and the guide sleeve is expensive due to the composite carbon fiber material, long in purchase period and incapable of meeting the field requirements;
4. the piston rod is sealed to lose efficacy, so that the two cavities of the cylinder barrel blow by gas, the piston rod does not act, and the cutting edge cannot be lifted to remove burrs;
5. because some plate types of the continuously cast supplied material plate blank are poor and are in a downward winding type, the length of the plate blank is shortened after being cut, the distance between the front roller way and the rear roller way of the deburring machine is large, the plate blank has obvious knocking and downward collision phenomena in the advancing process, and when the plate blank is advanced to the deburring machine, the cylinder frame of the deburring machine stops at a working waiting position, the plate type with serious knocking easily collides the cutting edge of the cylinder of the deburring machine, so that the equipment is damaged;
6. the deburring machine cutting edge is arranged on same axis along the knife rest, and all cutting edges are used on the slab burr simultaneously when getting rid of the burr, and the cutting burr is great for the reaction force of line contact production to the deburring machine this moment, and the slab often can't drive by the roll table, must increase the push rod effect and just can accomplish the burring operation, and great transverse force is unfavorable for the life of deburring machine cylinder and internals on the deburring cylinder.
The cylinder of the deburring machine does not act or is not in place and the like, the problem of the surface quality of a plate blank is directly influenced, if the blank which is not deburred or unclean in burr removal is heated, the blank is rolled again to press iron oxide burrs at the head and the tail of the formed steel plate, the surface quality of the steel plate is seriously influenced, the trimming amount is increased, the yield is reduced, and therefore once the deburring machine is found to be abnormal in the production process, the deburring machine must be stopped for rush repair treatment to ensure the functional precision of the deburring machine. However, a common deburring machine is composed of 25 blade cylinders, once any one or more blade cylinders do not act or blades are abnormal, a production worker cannot confirm the situation in the operating room at the first time, finally, a plate blank is heated by loading steel in a heating furnace, and is cooled in a cooling bed area after being rolled by a rolling mill, quality inspection workers find that the head and the tail of the steel plate have quality defects, and then feedback information to a wire binding production worker, the quality problems of batch quality are caused, and in severe cases, the furnace blank needs to be returned to the furnace after being completely blocked, so that the normal production operation is greatly influenced.
