Abstract
The utility model discloses a knife rest return device of a plate shearing machine. The knife rest return device comprises a knife rest body, an oil cylinder and a spring, wherein the spring is detachably connected to the knife rest body, and the oil cylinder is pressed on the knife rest body through a piston. According to the utility model, the energy is saved, and the knife rest return device is safer.
Description
Technical field
The utility model relates to a kind of forging equipment field, is specifically related to a kind of tool rest return stroke device of plate shearing machine.
Background technology
Existing tool rest return stroke device uses is that kicker cylinder fills storage nitrogen so that tool rest return stroke, like this will working pressure containers store nitrogen, and nitrogen loses easily, in case the loss back tool rest can't be got back to initial point.
The utility model content
The utility model purpose: the purpose of this utility model is in order to remedy the deficiencies in the prior art, to provide a kind of safer, and energy-conservation plate shearing machine tool rest return stroke device.
Technical scheme: a kind of plate shearing machine tool rest return stroke device, described tool rest return stroke device comprises tool holder body, oil cylinder, also comprises spring, and described spring removably is connected on the tool holder body, and oil cylinder is pressed on the tool holder body by piston.
Described spring is arranged on the tool holder body by the screw peace pad assembly of spring upper end and the spring base of spring lower end.
Beneficial effect: the utility model has adopted after such structure, cost efficiency, and simple installation, failure rate is low, energy-conservation.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Specific embodiment
A kind of plate shearing machine tool rest return stroke device, described tool rest return stroke device comprises tool holder body 1, oil cylinder 2, also comprises spring 3, and described spring 3 removably is connected on the tool holder body 1, and oil cylinder 2 is pressed on the tool holder body 1 by piston.Described spring 3 is arranged on the tool holder body 1 by the screw peace pad assembly 4 of spring upper end and the spring base 5 of spring lower end.
Behind the electric motor starting oil pump feed, step on floor push and make electromagnetic valve work, through the valve group piston of oil cylinder is stretched out downwards in hydraulic oil, so that knife rest integral body is descending, with spring-compressed, thereby with plate cutting.Unclamp floor push after having cut plate, magnetic valve dead electricity hydraulic oil no longer enters oil cylinder, and at this moment spring stretches, and knife rest will be made drawback movement.
