Abstract
Disclosed is an edge-pressing mechanism of a digital control hydraulic right angle plate shearing machine, which relates to the machining equipment, in particular to the structural technique field of the digital control hydraulic right angle plate shearing machine. The edge-pressing mechanism is mainly composed of a separating oil block, at least four groups of oil cylinders, a pressing block and tension springs, a main oil way is arranged in the separating oil block, one end of the main oil way is connected with an oil supply system, and juxtaposed branch oil ways having the same number with the oil cylinders are also disposed in the separating oil block; and oil cylinders of each group are vertically connected to the lower end of the separating oil block respectively, cylinder bodies of oil cylinders of each group are fixedly connected with the separating oil block, the upper ends of piston rods of oil cylinders of each group are relative to one branch oil way, the lower ends of piston rods of each group are connected with the pressing block, and the tension springs are connected between the pressing block and the cylinder bodies of the oil cylinders. The high pressure oil enters the separating oil block and then is distributed to each oil cylinder by the separating oil block, and the high pressure oil pushes the piston rods to move downwards, thereby driving the pressing block to press against plates. When in return travel, the high pressure oil is firstly unloaded, and the tension springs spring back to drive the pressing block to restore to the position.
Description
Technical field
The utility model relates to machining equipment, particularly the technical field of structures of numerical control hydraulic right-angled plate shearing machine.
Background technology
As everyone knows, the numerical control hydraulic right-angled plate shearing machine adds man-hour to workpiece, needs earlier to apply downward pressure to the plate of processing, with fixing plate, just can carry out punching.Present feeding pressure mechanism is: arrange in the lower end of slide block by mechanical action, to make slide block down by many group springs that apply pressure-plate-force downwards by the spring on it, because maximum pressure-plate-force is smaller, when processing plate so, workpiece accuracy is undesirable.Limited by machine tool structure, the organization plan that adds big spring can't be implemented, so present numerical control hydraulic right-angled plate shearing machine is because the pressure-plate-force deficiency causes the affected defective of machining accuracy to be difficult to overcome.
The utility model content
The utility model purpose is to design a kind of blank body that can improve the numerical control hydraulic right-angled plate shearing machine of machining accuracy.
The utility model mainly is made up of a minute oil clot, four group oil cylinders, binder block and extension spring at least, divides in the oil clot total oil circuit is set, and an end of total oil circuit is connected with oil supply system, divides the branch oil circuit that be arranged in juxtaposition identical with the oil cylinder number also is set in the oil clot; Each group oil cylinder is upright respectively to the lower end that is connected the branch oil clot, the cylinder body of every group oil cylinder is fixedlyed connected with dividing oil clot, the piston rod of every group oil cylinder upper end and one fen oil circuit positioned opposite, the lower end of every group of piston rod connects a binder block, is connected extension spring between the cylinder body of described binder block and oil cylinder.
Hydraulic oil enters into the branch oil clot, is assigned to each oil cylinder by a minute oil clot again, and hydraulic oil promotes piston rod and moves down, and pushes down plate thereby promote binder block.During backhaul, the off-load of hydraulic oil elder generation, the extension spring resilience drives binder block and resets.
The utility model is simple in structure, and the synchronism of each group oil cylinder is good, can improve pressure-plate-force greatly, and the machining accuracy of numerical control hydraulic right-angled plate shearing machine is improved greatly.Because need not power consumption during backhaul, so, can also energy savings.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is a C-C cut-away enlarged view among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the utility model mainly is made up of minute oil clot 1, eight group oil cylinders 2, eight binder blocks 3 and eight groups of extension springs 4.
Divide in the oil clot 1 total oil circuit 1-1 is set, an end of total oil circuit is connected with oil supply system, divides in the oil clot 1 also to be provided with and eight branch oil circuit 1-2 that are arranged in juxtaposition.
Each group oil cylinder 2 is upright respectively to the lower end that is connected branch oil clot 1, the cylinder body 2-1 of every group oil cylinder 2 is fixedlyed connected with dividing oil clot 1, piston rod 2-2 upper end and one fen oil circuit 1-2 positioned opposite of every group oil cylinder 2, the lower end of every group of piston rod 2-2 connects a binder block 3, be connected extension spring 4 between the cylinder body 2-1 of binder block 3 and oil cylinder 2, extension spring 4 can be enclosed within outward outside the cylinder body 2-1, and the upper end of extension spring 4 connects cylinder body 2-1, and the lower end connects binder block 3.
