Description
Technical field
The present invention relates to automobile production field, particularly a kind of tapered wedge rotating mechanism.
Background technology
Along with the progress of auto industry, auto parts and components appearance requirement is more and more higher, and production automation degree is also come higher.In automobile production, punch forming process is because cost is low, efficiency is high and be widely applied.In diel, due to the application of rotary tapered wedge, for minimizing stamping procedure step, saving die size, reduction die cost create more wide chance.
In prior art, rotary tapered wedge has two kinds of supporting way: one is rotating shaft terminal brace type, and one is rotational slide face brace type.These two kinds of modes are only applicable to flange, the shaping of the stamping parts in stamping parts 1m and following size range, for the large scale stamping parts of more than 1.2m, there is following problem in prior art: for rotating shaft terminal brace type, after wedge size increases, because the rotating shaft only by two ends supports, therefore mid portion easily bends, and the machining accuracy of product reduces; For rotational slide face brace type, must ensure the machining accuracy in wedge sliding support face, therefore wedge size is larger, and the production cost of mould is higher, difficulty is larger.
Summary of the invention
The object of the present invention is to provide one to ensure processing precision of products, be easy to again the rotary tapered wedge of the production of mould, to be applicable to the processing of large scale stamping parts.
For achieving the above object, The embodiment provides following technical scheme:
A kind of tapered wedge rotating mechanism, comprising:
Die shoe;
Drive division;
Backhaul portion;

Detailed description of the invention
Fig. 1 is the sectional view of the rotary tapered wedge of embodiments of the invention, and wherein diagrammatically illustrates the position of the rotating shaft 101 of rotating part 10.Drive division 5 is positioned at the top of rotating part 10, for pressing down rotating part 10 at work, makes rotating part 10 rotate into operating position.General drive division 5 is installed on the upper bolster 1 corresponding with die shoe 11.At the upper surface of rotating part 10, be provided with secondary drive seat 6 by modes such as welding, bolt connections, for coordinating the motion of wedge slide block at work, its operation principle will be explained in further detail hereinafter.Preferred secondary drive seat 6 mode with bolts, is convenient to coordinate different wedge slide blocks, changes different secondary drive seats.Those of ordinary skill in the art can imagine, and it is common in the prior art, secondary drive seat 6 can not be there is, directly coordinated with wedge slide block by rotating part 10 and finish the work, but removable secondary drive seat 6 can coordinate different wedge slide blocks, therefore improve the versatility of rotary tapered wedge, therefore have more advantage.The modes such as arc shaped slider 9 is bolted, weld, embedding are fixed on the lower surface of rotating part 10, and preferred bolt connects.The modes such as curved support seat 8 is bolted, weld, embedding are fixed on die shoe 11, and preferred bolt connects.Arc shaped slider 9 has the arcuate surface portions of evagination, and curved support seat 8 has the arcuate surface portions of indent, and two arcuate surface portions shapes are coincide, make arc shaped slider 9 can with curved support seat 8 relative sliding.Certainly, those of ordinary skill in the art can imagine, arc shaped slider 9 can have the arcuate surface portions of indent, and correspondingly, curved support seat 8 can have the arcuate surface portions of evagination.Backhaul portion 7 is arranged on die shoe 11, and is positioned at the below of rotating part 10, for making rotating part 10 remain on initial position in a non-operative state, and returns back to initial position in the end-of-job stage.Drive division 5 and backhaul portion 7 are positioned at the same side of the rotating shaft 101 of rotating part 10.
Fig. 2 is the stereogram of the rotary tapered wedge of embodiments of the invention, in order to clear, removes die shoe 11.The two ends of rotating part 10 have rotating shaft 101.Bearing shell 102 is made up of upper and lower two panels, is preferably manufactured by high-abrasive material.The upper and lower two panels of bearing shell 102 fits together, and maintains rotating shaft 101, and then bearing shell 102 is installed on die shoe 11 by bolt.Due to the existence of split type bearing shell 102, make the dismounting between rotating part 10 and die shoe 11 more convenient, and the wearing and tearing of rotating shaft 101 can be reduced.Along the axial direction of rotating part 10, be furnished with multipair arc shaped slider 9 and curved support seat 8.In the course of work of rotating part 10, supporting seat 8 is that the part of rotating part 10 between two rotating shafts 101 provides support, and can effectively prevent rotating part 10 to be out of shape.And, add man-hour when what need to carry out large-scale stamping parts, according to the size of required rotating part 10, only need arrange in the axial direction a pair or multipair arc shaped slider 9 and curved support seat 8, easily realize.Therefore, arc shaped slider 9 is preferably with bolts with curved support seat 8, installs more convenient.Another advantage with bolts is, once arc shaped slider 9 has had influence on the machining accuracy of stamping parts with the degree of wear of curved support seat 8, then can change them rapidly.
Fig. 3 basically illustrates the structure in drive division 5 and backhaul portion 7 in the present embodiment.Drive division 5 is made up of drive link 53 and nitrogen spring 54, is installed on upper bolster by lining 51.One end of drive link 53 is connected with nitrogen spring 54, and the other end is provided with roller 52.When upper bolster 1 presses down, nitrogen spring 54 can promote drive link 53 and move downward, and then rotating part 10 is rotated.The sliding friction that rotating part 10 produces in rotary course and between drive division 5 can be converted into rolling friction by roller 52, reduces wearing and tearing.Similarly, backhaul portion 7 can adopt the structure identical with drive division 5.Those of ordinary skill in the art can imagine, drive division 5, backhaul portion 7 can adopt other suitable structure to realize driving, return function equally.
Fig. 4 indicates the operation principle of the flanging die of the rotary tapered wedge adopting embodiments of the invention.On upper bolster 1, material pressing core 2 is installed.Wedge slide block 4 is slidingly mounted on upper bolster 1.The stamping parts 3 carrying out side flanging processing is needed to be placed on die shoe 11.In an initial condition, backhaul portion 7 supports rotating part 10 and is in initial position.Along with upper bolster 1 presses down, drive division 5 presses down rotating part 10, makes rotating part 10 rotate into operating position around its rotating shaft, and the nitrogen spring in backhaul portion 7 is compressed.Meanwhile, wedge slide block 4 contacts with secondary drive seat 6, and secondary drive seat 6 promotes wedge slide block 4 and slides in the horizontal direction, coordinates with rotating part 10, completes the flange work of stamping parts 3.As seen from the figure, the right-hand member of stamping parts 3 completes flange, occurs a negative angle.After flange completes, upper bolster 1 lifts, and drive division 5 and rotating part 10 depart from, and under the effect in backhaul portion 7, rotating part 10 rotates and is returned to initial position, is convenient to the taking-up of stamping parts 3.In the whole course of work, along with the rotation of rotating part 10, arc shaped slider 9 rotates simultaneously in curved support seat 8, and curved support seat 8 provides support for rotating part 10, prevents rotating part 10 in punching course to be out of shape.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present invention and scope.
