Description

Technical Field

[0001] The utility model relates to a punching device, in particular to a device capable of punching the surface of a sintering trolley to improve air permeability, belonging to the technical field of trolley surface punching equipment. Background Technique

[0002] In the length direction of the sintering machine, there are large differences in the air permeability of the material layer; a large amount of air is required for the sintering process. If the surface of the trolley is too dense, it will lead to poor air permeability and affect the sintering process; when the air permeability of the material layer is poor, the vertical burning speed of the mixed material decreases, the efficiency of the induced draft fan system drops, resulting in an increase in the overall energy consumption of the sintering process and a decrease in the sintering productivity and economic and technical indicators; in order to improve the air permeability of the trolley material layer, the current method is to set a roller above the trolley, and steel nails are arranged on the side wall of the roller. The steel nails are pressed into the surface of the material layer by the self-weight of the roller to punch holes, thereby improving air permeability. However, the punching position of this method lags behind, the air permeability cannot be guaranteed, and the uniformity of punching cannot be controlled; therefore, a punching device is needed, which is required to be able to punch the surface of the trolley evenly, thereby improving the air permeability of the trolley surface.

[0019] Working principle: When it is necessary to punch the surface of the trolley material, the electric cylinder 7 drives the vertical slide plate 6 to move downward. When a certain trolley touches the pressure contact plate 8 along its upper edge during its forward movement and drives the long slide plate 2 to slide synchronously, the spring between the first vertical plate 3 and the second vertical plate is stretched. After the pressure contact switch triggers a signal, the hydraulic cylinder 13 drives the lifting plate 16 to move downward, and the plug rods 17 at the bottom end of the lifting plate punch the surface of the trolley material. After the piston rod of the hydraulic cylinder 13 extends and retracts, a row of holes are punched. Then the motor operates to drive the lead screw nut to move, and then the hydraulic cylinder 13 operates again to punch holes. The lifting plate 16 continuously moves along the length direction of the trolley and stops to punch holes; during this process, the first infrared distance measuring instrument 5 continuously monitors the distance between the vertical slide plate 6 and the horizontal plate 1. When the vertical slide plate 6 approaches the horizontal plate 1, the electric cylinder 7 drives the vertical slide plate to move upward to disengage from the push of the trolley. At this time, the spring between the first vertical plate 3 and the second vertical plate drives the long slide plate 2 to reset; the motor drives the lead screw nut back to the initial position; when the first infrared distance measuring instrument 5 senses that the long slide plate has been reset, the electric cylinder drives the vertical slide plate 6 to move downward again, contacts the upper edge of the next trolley and is pushed, and then repeats the above actions to punch the surface of the material of this trolley, and so on.
