Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 to 3, the embodiment discloses a pusher for producing a medium plate, which includes a base 1, a hydraulic cylinder 2, a pusher head 3, and guide rods 4 arranged on two sides of the hydraulic cylinder 2, wherein the guide rods 4 are connected to the base 1 through guide sleeves.
Two C-shaped channel steel guide rails 5 are arranged below the push head 3 side by side along the pushing direction, and the C-shaped channel steel guide rails 5 are arranged between two rollers of the conveying roller way 15. A slide rail trolley 6 is arranged in the C-shaped channel steel guide rail 5, and the frame body of the slide rail trolley 6 is fixedly connected with the push head 3 above. Under the drive of pneumatic cylinder 2, the pushing head 3 passes through slide rail dolly 6 and moves on C shape channel-section steel guide rail 5, and when pneumatic cylinder 2 and guide bar 4 moved to the biggest stroke, slide rail dolly 6 can play the supporting role to anterior pushing head 3, can not produce the countersunk head phenomenon.
