Abstract
The invention relates to a matched die in forging and stamping mechanical equipment, in particular to a heavy-load internal force balanced type automatic variable pitch bending lower die. The lower die is provided with a base plate of which one side is provided with a lower die body, and is characterized in that: a push-and-pull mechanism is arranged on the other side of the base plate, and a push rod head of the push-and-pull mechanism is connected with the lower die body through a connecting block; a plurality of splayed grooves are formed on the base plate; a plurality of pairs of sliding keys which are arranged in a splayed shape are arranged in the splayed grooves on the base plate corresponding to the bottom surface of the lower die body; the sliding keys are fixedly connected with the lower die body, and are in clearance fit with the splayed keys on the base plate; the lower die body are formed by engaging two L-shaped die piece groups oppositely; and the sliding keys which are arranged in the splayed shape are arranged on the two L-shaped die piece groups from two sides. The heavy-load internal force balanced type automatic variable pitch bending lower die solves the problems of complex structure, poor adjusting accuracy of opening distance, inconvenient operation and the like in the conventional opening adjustable lower die, and is mainly used for panel veneer bending machines.
Description
(1) technical field: the present invention relates to the matching die in the forging machinery and equipment, especially a kind of heavy-load type internal force balance formula automatic adjustable-pitch bending counterdie.
(2) background technology: at present, the bending counterdie that uses on the bender has two kinds of forms: a kind of is the bending counterdie of permanent opening distance, and this counterdie is simple in structure, also is the form that generally adopts at present.But because the variation of bending workpieces material thickness and radius of corner, the counterdie extended distance also will corresponding change, and the counterdie that this just causes wanting frequent change different openings distance has influenced the operating efficiency of machine and increased operator's labour intensity.A kind of in addition is to the shortcoming of permanent opening apart from counterdie; The adjustable counterdie of a kind of tooth-shape structure opening by the exploitation of Sweden Wu Siweiken company; In order to overcome the horizontal component in the bending process, adopted a cover locking device after opening is adjusted, to lock, accomplish the plate bending again.Though this version has solved the problem of frequent change counterdie, locking device requires enough intensity to overcome horizontal component, makes structure very complicated, and in the locking process, influences the precision of extended distance, and operation simultaneously is also inconvenient.
(3) summary of the invention: the object of the invention will solve the existing adjustable counterdie complex structure of opening exactly, inconvenient operation, and problems such as extended distance degree of regulation difference provide a kind of heavy-load type internal force balance formula automatic adjustable-pitch bending counterdie.
Concrete scheme of the present invention is: be designed with seat board, Yi Bian lower mold body is housed on the seat board, it is characterized in that: another side is installed push-pull mechanism on seat board, and its push rod cup is connected with lower mold body through contiguous block; On seat board, have some Eight characters grooves, the Eight characters groove on the corresponding seat board in the bottom surface of lower mold body is equipped with that some all slide keys are fixedly connected with lower mold body to being the slide key that splayed is arranged, and is connected movingly with Eight characters groove on the seat board; Said lower mold body is meshed by two groups of L shaped matrix groups relatively to be formed, and the said slide key branch both sides that are the splayed layout are arranged on two groups of L shaped matrix groups.
L shaped matrix group described in the present invention connects one by some L shaped matrixs through pull bar and forms; Every L shaped matrix is made up of base plate and vertical panel, and the thickness of base plate is the half the of vertical panel thickness, and the bottom surface of every L shaped matrix is designed to cascaded surface, wherein on bottom surface, has the angle keyway, and ladder height is greater than the keyway degree of depth; In lower mold body, adjacent in twos L shaped matrix, its base plate embedding engagement are relatively mutually arranged.
In order to guarantee operating accuracy, it is firm to lock, in the Eight characters groove of offering on the base plate described in the present invention every groove have a sidewall design be waveform from locking face, the corresponding side surface of corresponding all slide keys is designed to waveform from locking face.
The push-pull mechanism of installing on the base plate described in the present invention includes a sleeve screw rod pair of nut, and its nut is an one with being connected packaged, and its screw mandrel is by driven by servomotor, and servomotor is fixedly mounted on the end of base plate.
In order to guarantee working stability, accurate, on base plate, be parallel to the screw mandrel both sides among the present invention and be furnished with two guide rails, on two guide rails a transverse slider is housed, transverse slider is installed on the contiguous block.
Operation principle of the present invention is: start the driven by servomotor screw mandrel and drive whole lower mold body motion through nut, contiguous block; Slide key on two groups of L shaped matrix groups in lower mold body; Will be along the Eight characters groove guiding movement on the seat board; Thereby make two groups of L shaped matrix groups when seesawing, realize the variation of extended distance, open or draw in.On seat board, be provided with two guide rails among the present invention, transverse slider be housed be connected, make the lower mold body motion more reliable and more stable with contiguous block.Among the present invention in the seat board chute with slide key on design wave shape from locking face, can make the lower mold body extended distance realize self-locking, to guarantee operating accuracy.
The present invention designs ingenious, and is simple in structure, reliable operation, and precision is high; The configuration digital control system can realize numerical controlization, through the control of digital control system, realizes the automatic adjustment of counterdie opening, and need not the locking device auto lock after making the counterdie displacement through internal force balance, has guaranteed the precision of counterdie opening; The present invention's one cover counterdie can satisfy the bending needs of different thicknesss of slab and different radiuss of corner.
