Abstract
The utility model relates to a hydraulic locking device for a material pinching table of a cold header. The device comprises an air source, a hand-operated valve, a pressure regulating valve, a pneumatic oil pressure pump, an oil pressure meter, two air pressure electromagnetic valves, two pneumatic valves, two corner pressing cylinders and an oil cylinder, wherein the air source is sequentially connected with the hand-operated valve, the pressure regulating valve, the pneumatic oil pressure pump and the oil pressure meter; an outlet of the oil pressure meter is connected with inlets of the pneumatic valves respectively; reversing control ports of the pneumatic valves are connected in parallel between the voltage regulating valve and the hand-operated valve after passing through the air pressure electromagnetic valves respectively; and an outlet of the oil cylinder is connected in parallel with inlets and outlets of the corner pressing cylinders after passing through the pneumatic valves respectively. The hydraulic locking device also comprises two pressure switches, and the pressure switches are arranged between the pneumatic valves and the inlets of the corner pressing cylinders and between the pneumatic valves and the outlets of the corner pressing cylinders respectively. The pneumatic oil pressure pump is also connected with the oil cylinder. The hydraulic locking device is easy to operate and low in error rate, human factors are reduced, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of locking device, and cold headers are held material platform hydraulic locking apparatus under the arm specifically.
Background technology
The material platform of holding under the arm of cold-heading equipment mostly is the mechanical lock mode at present, as shown in Figure 2, be specially a supporting seat 3, there are a pull rod shaft 5 and a coil tension spring 4 in inside, by one handle 1 be connected with connecting axle 6 after the band 2 pairs of dynamic pressure plates hold under the arm the material platform 7 compress action, but often hold under the arm the material platform dig in the process, hold down gag just gently leaves and does not turn over certain angle, the operator easily forgets and does not unclamp at present the phenomenon that puts in place and dig with regard to the direct control reductor and hold the material platform under the arm, reductor shaft is with holding material platform upper sprocket wheel under the arm for directly linking to each other, directly drive to dig and cause stressed too greatly in the process, reductor is broken down with whole the drawing of base that lathe bed links to each other.
