Description
Technical field
The utility model belongs to hydraulic pressure processing equipment technical field, particularly relates to a kind of simple in structure, hydraulic press numerical control mobile pressure head clamping device that can improve press punching operation stability.
Background technology
At present the tradition hydraulic press action and the control mode when work that are used for hull processing comparatively oversimplified, and the punching press pressure head of hydraulic press can only simply move up and down, and this hydraulic press can not satisfy the use of present shipbuilding industry.Along with the birth of moving revolution pressure head frame hydraulic press, thereby brought bigger convenience for the manufacturing process of shipbuilding industry, the seaming chuck of this hydraulic press not only can carry out 360 ° of rotations when the processing hull plate, but also can be on the entablature of hydraulic press move left and right, like this, on hydraulic press drive Mould Machining hull plate, replaced the operation that a lot of artificial mechanisms moved and rotated steel plate, and moved the whole punching course that revolution frame pressure head hydraulic press is finished hull plate different directions and different angles by numerical control.In punching course, will produce bigger impulsive force owing to move revolution frame pressure head hydraulic press, if when hull plate is carried out punch process, not to the removable revolution pressure head of hydraulic press secure in addition, so will destroy the stability of hydraulic press in whole punching course, make the pressure head dislocation, so also just seriously influenced the accurate forming of hull plate.
Summary of the invention
The utility model provides a kind of simple in structure, hydraulic press numerical control mobile pressure head clamping device that can improve press punching operation stability for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Hydraulic press numerical control mobile pressure head clamping device; it is characterized in that: its building block comprises piston; clamping cylinder; the dish spring; protective sleeve; dish spring abutment and locknut are formed; described piston is installed in the clamping cylinder cylinder body; in the clamping cylinder cylinder body, isolate formation upper cavity and lower chamber by piston; the dish spring is placed in the upper cavity; it is the generation source of clamping device clamping force; by dish spring stress deformation curve; determine to clamp and loosen the relation of deflection and required pressure; lower chamber has one and is used to the into oil-in of pressure oil; this oil-in is communicated with the clamping cylinder cavity of resorption; numeral by oil pressure shows; thereby control the size that clamps and loosen oil pressure; in order to prevent that the dish spring is destroyed under overload situations; in upper cavity, also be provided with the protective sleeve of a protection dish spring; lay a dishful of spring abutment in dish spring upper surface; be used for firm dish spring; this dish spring abutment upper end is provided with locknut; piston; the dish spring; protective sleeve and dish spring abutment are one by locknut and clamping cylinder cylinder bottom lock; lay a backing plate on the clamping cylinder cylinder bottom, cylinder body and backing plate are by bolt and the locking of travelling car supporting plate.
Described dish spring abutment has a groove that is used for firm dish spring.
Have on the described backing plate and be used for the elongated slot that the compression of dish spring forms the upper cavity exhaust.
Advantage and the good effect that the utlity model has are:
Owing to adopted this technical scheme, entering cylinder body by clamping device pressure oil promotes to move on the piston, thereby compact disc spring, cylinder body drives travelling car and moves down, move down into specified altitude assignment, the beginning pressurize, the ring flange of fastening travelling car and the attachment screw of cylinder body, the upper beam lower plane of cylinder body half the circumference of the sleeve where it joins the shoulder and press is fitted, clamping is finished in pressure release, eight covering devices use simultaneously and can firmly be fixed in the face of getting on the right track to travelling car, make the clamping cylinder cylinder body firmly be fixed in upper beam lower railway face simultaneously, improved the stability of hydraulic press in whole punching course, can prevent to move the revolution pressure head and misplace because of being subjected to greater impact power, guarantee the accurate forming of hull plate, thereby for the manufacturing process of shipbuilding industry machining large steel plate has been brought many convenience, the utility model reasonable in design, easy and simple to handle, practical, have bright development prospect.

Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the utility model user mode figure.
Among the figure: 1 working head, 2 hydraulic press master cylinders, 3 travelling cars, 4 are put the beams in place, 4-1 gets on the right track, 4-2 upper beam lower railway, 5 numerical control mobile pressure head clamping devices, 6 rollers, 7 pistons, 8 clamping cylinders, 8-1 oil-in, 9 dish springs, 10 protective sleeves, 11 dish spring abutments, 12 locknuts, 13 backing plates, 14 travelling car supporting plates, 15 dish spring abutment grooves, 16 backing plate elongated slots.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2; hydraulic press numerical control mobile pressure head clamping device; its building block comprises piston 7, clamping cylinder 8, dish spring 9, protective sleeve 10, dish spring abutment 11 and locknut 12 compositions; described piston 7 is installed in clamping cylinder 8 cylinder bodies; the clamping cylinder cylinder body is isolated formation upper cavity and lower chamber by piston 7; lay dish spring 9 in the upper cavity, lower chamber has one and is used to the into oil-in 8-1 of pressure oil, and this oil-in is communicated with the clamping cylinder lower chamber.In upper cavity, also be provided with the protective sleeve 10 of a protection dish spring; be mounted with dish spring abutment 11 in dish spring upper surface; described dish spring abutment has a groove 15 that is used for firm dish spring; this dish spring abutment upper end is provided with locknut 12; piston, dish spring, protective sleeve and dish spring abutment are one by this locknut and clamping cylinder cylinder bottom lock; on the clamping cylinder cylinder bottom, lay a backing plate 13; have the elongated slot 16 that is used for the exhaust of dish spring compression formation upper cavity on the described backing plate, cylinder body and backing plate are by bolt and 14 lockings of travelling car supporting plate.
