Abstract
The utility model relates to a hydraulic clamping device for a lower die of a numerical control plate bending machine and belongs to the field of a matched technology of the numerical control plate bending machine. A small oil cylinder and a pressing plate at the end of a power output shaft of the small oil cylinder are fixed on a clamping pedestal; when the lower die is embedded into a clamping pedestal, a certain gap between the pressing plate and the lower die is guaranteed; during operation, hydraulic oil enters, the small oil cylinder is propped against the pressing plate, and the pressing plate and the propping side of the inner end of the clamping pedestal clamp the lower die; and when operation stops, the pressing plate does not have pressure and the lower die can be disassembled and replaced easily and freely. The hydraulic clamping device for the lower die of the numerical control plate bending machine is simple and compact in structure, has the advantages of mechanical self-lock and automatic wear compensation, contributes to improving the work efficiency and has high practicability.
Description
Technical field
The utility model relates to a kind of digital control plate bending machine counterdie hydraulic clamp, belongs to digital control plate bending machine supporting technology field.
Background technology
Existing digital control plate bending machine is that the hydraulic clamp by integral body is fixed on counterdie on the middle riser of frame, this structure and fixed form thereof only are confined to single ∨ counterdie hydraulic clamp commonly used on the market, and the replacing time is long, affects the raising of operating efficiency.Can not be applicable to the counterdie of many ∨ centering counterdie and 2 ∨-T-shaped quick change, the counterdie hydraulic clamp of this structure, applicability is too little, if change frequently thickness of slab, then the opening of counterdie just needs change, the counterdie that just needs the multiple notch of customization, if use many V centering counterdie just can adapt to the requirement of various thicknesss of slab, and do not need a large amount of single V moulds, and very convenient during the transposing notch, do not need to readjust counterdie, directly change and just can continue to use, can save like this dismounting and the clamping of a lot of moulds, and the single V hydraulic clamp complicated structure that uses now, price is higher, renewal part is very inconvenient, if use existing our design the counterdie hydraulic clamp could effectively solution problems, simple in structure, renewal part is convenient, price is low, applicability is wide.
Summary of the invention
The purpose of this utility model provides a kind of digital control plate bending machine counterdie hydraulic clamp, solve the structure above shortcomings of existing digital control plate bending machine counterdie, realize being applicable to the counterdie of many ∨ centering counterdie and 2 ∨-T-shaped quick change by the utility model, have the advantage of compact conformation, mechanical self-latching, auto-compensation wearing and tearing.
The purpose of this utility model is achieved through the following technical solutions, and a kind of digital control plate bending machine counterdie hydraulic clamp is characterized in that described device is made of pressing plate, small oil tank, rebound, pressing plate, clamping base; Clamp on the base rebound and small oil tank are set, pressing plate is through being bolted to an end that clamps base and rebound, and power output shaft one end of small oil tank is through the bolt fixation clip.
The cascaded surface that matches with the rebound external form is set on the described clamping base, inserts small oil tank in the cavity of rebound.
Form the groove of placing counterdie a little more than the pressing plate that clamps plane on the base and the limit of supporting that clamps base the inner.
The utility model is by arranging the pressing plate of small oil tank and small oil tank power output shaft end, and be fixed on the clamping base, when counterdie embeds the clamping base, guaranteeing has certain gap between pressing plate and the counterdie, hydraulic oil enters during work, small oil tank resists pressing plate, pressing plate clamps counterdie with the limit of supporting that clamps base the inner, when quitting work, pressing plate is without pressure, counterdie can be easily dismounting and change freely, the utility model is simple and compact for structure, have the advantage of mechanical self-latching, auto-compensation wearing and tearing, be conducive to increase work efficiency, have very strong practicality.
Description of drawings
Fig. 1 is that the utility model is fixed on the sectional structure schematic diagram on the frame;
Among the figure, 1 counterdie, 2 pressing plates, 3 small oil tanks, 4 rebounds, 5 pressing plates, 6 clamp bases, riser in 7,8 bolts, 9 bolts, 10 bolts.
The specific embodiment
Further specify in conjunction with the accompanying drawings and embodiments the utility model, as shown in Figure 1, the utility model is made of pressing plate 2, small oil tank 3, rebound 4, pressing plate 5, clamping base 6.During use, clamping base 6 exhausted bolts 8 are fixed on middle riser 7 upper ends of frame, clamp on the base 6 rebound 4 and small oil tank 3 are set, pressing plate 5 is fixed on an end that clamps base 6 and rebound 4 through bolt 9, power output shaft one end of small oil tank 3 is through bolt 10 fixation clips 2, clamp the cascaded surface that matches with rebound 4 external forms is set on the base 6, insert small oil tank 3 in the cavity of rebound 4, form the groove of placing counterdie 1, small oil tank 3 external hydraulic circuits a little more than the pressing plate 2 that clamps plane on the base 6 and the limit of supporting that clamps base 6 the inners.
