Abstract
The utility model provides a connection apparatus for an upper knife rest and a cylinder of a plate shearing machine, comprising an engineering cylinder, an upper cylindrical pin, a lower cylindrical pin and a support frame, wherein the upper cylindrical pin is used for fixing the upper end of the engineering cylinder onto a cylinder seat; and the lower cylindrical pin and the support frame are used for fixing the lower end of the engineering cylinder onto the upper knife rest. The connection apparatus for the upper knife rest and the cylinder of the plate shearing machine adopts the structure form of single return stroke of the engineering cylinder and shearing of a main cylinder to effectively overcome the defects existing in the connection between a hanger rod and a double-headed screw, and solve the problem that leakage is easy to occur due to the excessive return stroke pressure of the lower chamber of a right cylinder. In addition, a hydraulic system does not need to be changed.
Description
Technical field
The utility model relates to a kind of plate shearing machine upper tool post and oil cylinder jockey, belongs to machinery manufacturing technology field.
Background technology
QC11Y Series Hydraulic lock formula plate shearing machine commonly used at present, the type of attachment of oil cylinder and knife rest mostly adopts and is rigidly connected and suspension rod and double threaded screw, because the restriction in the diameter of double threaded screw and space (can not select too large diameter double threaded screw); When moving up and down, lean on by the hydraulic oil cylinder driving upper tool post double threaded screw to connect; Double threaded screw bears the alternate load of per minute up and down 10-20 time, is easy to be stretched, and makes between knife rest and oil cylinder and produces the gap; Produce when moving up and down and impact; Time is long more, and double threaded screw, suspension rod are just broken, and this is the ubiquitous problem of QC11Y Series Hydraulic lock formula plate shearing machine.Particularly heavy duty machine tools are because knife rest weight is heavier, and the resistance that double threaded screw overcame is big more, and the probability of failure that is taken place is high more, and poor safety performance.
Summary of the invention
The purpose of the utility model is the weak point that overcomes prior art, and a kind of plate shearing machine upper tool post and oil cylinder jockey are provided.
Plate shearing machine upper tool post of the utility model and oil cylinder jockey comprise the engineering cylinder, are used for being fixed to the last straight pin on the oil cylinder seat on the engineering cylinder and being used for engineering cylinder lower end is fixed to following straight pin and bracing frame on the upper tool post.
Plate shearing machine upper tool post of the utility model and oil cylinder jockey; Adopted the independent backhaul of engineering cylinder; The version that master cylinder is sheared has solved suspension rod effectively and has been connected the defective of existence with double threaded screw, and has overcome the excessive and problem of easy to leak of right oil cylinder cavity of resorption backhaul pressure simultaneously.And need not to change hydraulic system just can realize.
Description of drawings
Fig. 1 is the front view of the plate shearing machine that has upper tool post and oil cylinder jockey of the utility model.
Fig. 2 is the side view of the plate shearing machine that has upper tool post and oil cylinder jockey of the utility model.
Wherein, 1 is the engineering cylinder, and 2 is last straight pin, and 3 are following straight pin, and 4 is bracing frame, and 5 is left oil cylinder, and 6 is left oil cylinder seat, and 7 is right oil cylinder, and 8 is right oil cylinder seat, and 9 is upper tool post.
The specific embodiment
Like Fig. 1, shown in 2; The plate shearing machine upper tool post and the oil cylinder jockey of the utility model comprise engineering cylinder 1; Be used for engineering cylinder 1 upper end is fixed to oil cylinder seat (6; 8) the last straight pin 2 on and be used for engineering cylinder 1 lower end is fixed to following straight pin 3 and bracing frame 4 on the upper tool post 9, the backhaul drag effect of upper tool post 9 is at two straight pins.
The plate shearing machine upper tool post of the utility model and the course of work of oil cylinder jockey: left oil cylinder 5 epicoele oil-feeds, cavity of resorption oil gets into right oil cylinder 7 epicoeles (series connection cylinder mechanism) through oil pipe, and engineering cylinder 1 cavity of resorption is drained the oil, and makes upper tool post 9 parallel moving downward.Otherwise the 1 cavity of resorption oil-feed of engineering cylinder promotes left and right sides oil cylinder piston bar and moves upward, and left oil cylinder epicoele is drained the oil.Because engineering cylinder cavity of resorption remains certain working pressure, lets upper tool post can get back to initial point.
Claims (1)
1. plate shearing machine upper tool post and oil cylinder jockey is characterized in that, comprise the engineering cylinder, be used for being fixed to the last straight pin on the oil cylinder seat on the engineering cylinder and being used for engineering cylinder lower end is fixed to following straight pin and bracing frame on the upper tool post.
