Abstract
The invention relates to a hydraulic clamping device of a lower die of a numerical-control bending machine, and belongs to the technical field of assorted parts of numerical-control plate bending machines. The hydraulic clamping device is provided with a small cylinder and a pressure plate at a power output shaft end of the small cylinder, the pressure plate is fixed onto a clamping base, and when the lower die is embedded in the clamping base, a certain gap is assuredly reserved between the pressure plate and the lower die. During operation, hydraulic oil flows into the gap, the small cylinder is abutted to the pressure plate, and the lower die is clamped by the pressure plate and an abutting edge of the inner end of the clamping seat; and when operation is finished, pressure on the pressure plate is released, and the lower die can be easily and freely detached and replaced. The hydraulic clamping device is simple and compact in structure, has the advantages of mechanical self-locking and automatic abrasion compensation, is beneficial for improving work efficiency and is high in practicality.
Description
Technical field
The present invention relates to a kind of digital control plate bending machine counterdie hydraulic clamp, belong to digital control plate bending machine supporting technology field.
Background technology
Existing digital control plate bending machine is that the hydraulic clamp through 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, influences the raising of operating efficiency.Can not be applicable to the counterdie of many ∨ centering counterdie and 2 ∨-T type quick change, the counterdie hydraulic clamp of this structure, applicability is too little; If frequent replacing thickness of slab, then the opening of counterdie just needs change, just needs the counterdie of 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 when changing notch; Need not readjust counterdie, directly change and just can continue to use, can practice thrift the dismounting and the clamping of a lot of moulds like this; And single V hydraulic clamp structure more complicated, the price used now are higher; Renewal part is very inconvenient, if use existing our design the counterdie hydraulic clamp could this type of problem of effectively solution, simple in structure, renewal part convenient, price is low, applicability is wide.
Summary of the invention
The purpose of this invention is to provide a kind of digital control plate bending machine counterdie hydraulic clamp; Solve the above-mentioned deficiency of the structure existence of existing digital control plate bending machine counterdie; Realize being applicable to the counterdie of many ∨ centering counterdie and 2 ∨-T type quick change through the present invention, have compact conformation, mechanical self-latching, the advantage of compensate for wear automatically.
The objective of the invention is to realize that through following technical scheme a kind of digital control plate bending machine counterdie hydraulic clamp is characterized in that said device is made up 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 pressing plate.
The cascaded surface that matches with the rebound external form is set on the said clamping base, inserts small oil tank in the cavity of rebound.
The support limit inner with clamping base a little more than the pressing plate that clamps plane on the base forms the groove of placing counterdie.
The present invention is through being provided with the pressing plate of small oil tank and small oil tank power output shaft end, and is fixed in and clamps on the base, when counterdie embeds when clamping base; Guaranteeing has certain clearance between pressing plate and the counterdie, and hydraulic oil gets into during work, and small oil tank resists pressing plate; Pressing plate the support limit inner with clamping base clamps counterdie, and when quitting work, pressing plate does not have pressure; Counterdie can be easily dismounting and change freely, the present invention is simple and compact for structure, has mechanical self-latching, the advantage of compensate for wear automatically; Help increasing work efficiency, have very strong practicality.
Description of drawings
Fig. 1 is fixed on the sectional structure sketch map on the frame for the present invention;
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 the present invention in conjunction with accompanying drawing and embodiment, as shown in Figure 1, the present invention is made up of pressing plate 2, small oil tank 3, rebound 4, pressing plate 5, clamping base 6.During use; With clamping middle riser 7 upper ends that base 6 exhausted bolts 8 are fixed on frame; Clamp rebound 4 and small oil tank 3 are set on the base 6, pressing plate 5 is fixed on an end that clamps base 6 and rebound 4 through bolt 9, and 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 pressing plate that clamps plane on the base 62 and the limits of supporting that clamp base 6 the inners.
Claims (3)
1. a digital control plate bending machine counterdie hydraulic clamp is characterized in that, said device is made up 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 pressing plate.
