Description of drawings
Next will combine accompanying drawing that embodiments of the invention are done further explain, wherein:
Fig. 1 is the cutaway view of the rotation wedge of embodiments of the invention;
Fig. 2 is the stereogram of the rotation wedge of embodiments of the invention;
Fig. 3 is the partial enlarged drawing of Fig. 1;
Fig. 4 has shown the operation principle of the flanging die of the rotation wedge that adopts embodiments of the invention.
The specific embodiment
Fig. 1 is the cutaway view of the rotation wedge of embodiments of the invention, and has wherein schematically shown the position of the rotating shaft 101 of rotating part 10.Drive division 5 is positioned at the top of rotating part 10, is used for pressing down rotating part 10 at work, makes rotating part 10 rotate into the operating position.General drive division 5 be installed in die shoe 11 corresponding upper bolsters 1 on.At the upper surface of rotating part 10, through modes such as welding, bolt connections secondary drive seat 6 is installed, be used for cooperating at work the motion of wedge slide block, its operation principle will be explained in further detail hereinafter.Preferred secondary drive seat 6 adopts bolt connecting mode, is convenient to cooperate different wedge slide blocks, changes different secondary drive seats.Those of ordinary skills can imagine; And it is common in the prior art; Can there be secondary drive seat 6, directly cooperate by rotating part 10 and finish the work, but removable secondary drive seat 6 can cooperates different wedge slide blocks with the wedge slide block; Therefore improve the versatility of rotation wedge, therefore had more advantage.Arc shaped slider 9 is fixed on the lower surface of rotating part 10 through modes such as bolt connection, welding, embeddings, and preferred bolt connects.Arc supporting seat 8 is fixed on the die shoe 11 through modes such as bolt connection, welding, embeddings, and preferred bolt connects.Arc shaped slider 9 has the curved surfaces part of evagination, and arc supporting seat 8 has the curved surfaces part of indent, and two curved surfaces partial shapes coincide, and make arc shaped slider 9 to slide relatively with arc supporting seat 8.Certainly, those of ordinary skills can imagine that arc shaped slider 9 can have the curved surfaces part of indent, and correspondingly, arc supporting seat 8 can have the curved surfaces part of evagination.Backhaul portion 7 is installed on the die shoe 11, and is positioned at the below of rotating part 10, is used to make rotating part 10 under off working state, to remain on initial position, 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 rotation wedge of embodiments of the invention, for clear, has removed die shoe 11.The two ends of rotating part 10 have rotating shaft 101.Bearing shell 102 is formed by upper and lower two, preferably by the high-abrasive material manufacturing.Upper and lower two of bearing shell 102 fit together, and maintain rotating shaft 101, and bearing shell 102 is installed on the die shoe 11 through bolt then.Because the existence of split type bearing shell 102 makes that the dismounting between rotating part 10 and the die shoe 11 is more convenient, and can reduce the wearing and tearing of rotating shaft 101.Along the axial direction of rotating part 10, be furnished with many to arc shaped slider 9 and arc supporting seat 8.In the course of work of rotating part 10, supporting seat 8 provides support for the part of rotating part 10 between two rotating shafts 101, can effectively prevent rotating part 10 distortion.And, when needs carry out man-hour that adds of large-scale stamping parts,, only need on axial direction, to arrange a pair of or manyly arc shaped slider 9 and arc supporting seat 8 get final product realization easily according to the size of required rotating part 10.Therefore, arc shaped slider 9 is connected with the arc supporting seat 8 preferred bolts that adopt, and installs more convenient.Adopt bolted another advantage to be,, then can change them rapidly in case the degree of wear of arc shaped slider 9 and arc supporting seat 8 has had influence on the machining accuracy of stamping parts.
Fig. 3 mainly shows the structure of drive division in the present embodiment 5 and backhaul portion 7.Drive division 5 is made up of drive link 53 and nitrogen spring 54, is installed on the upper bolster through lining 51.One end of drive link 53 is connected with nitrogen spring 54, and the other end is equipped with roller 52.When upper bolster 1 pressed down, nitrogen spring 54 can promote drive link 53 and move downward, and then made rotating part 10 rotations.Roller 52 can be converted into rolling friction with the sliding friction that rotating part 10 produces in rotary course and between the drive division 5, reduces wearing and tearing.Similarly, backhaul portion 7 can adopt and drive division 5 identical construction.Those of ordinary skills can imagine that drive division 5, backhaul portion 7 can adopt other appropriate structures to realize driving, return function equally.
Fig. 4 has shown the operation principle of the flanging die of the rotation wedge that adopts embodiments of the invention.On upper bolster 1, binder core 2 is installed.Wedge slide block 4 is slidingly mounted on the upper bolster 1.The stamping parts 3 that need carry out side flanging processing is placed on the die shoe 11.Under original state, backhaul portion 7 is supporting rotating part 10 and is being in initial position.Along with upper bolster 1 presses down, drive division 5 presses down rotating part 10, makes rotating part 10 rotate into the operating position around its rotating shaft, and the nitrogen spring of backhaul portion 7 is compressed.Simultaneously, 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, cooperates with rotating part 10, accomplishes the flange work of stamping parts 3.Visible from figure, the right-hand member of stamping parts 3 has been accomplished flange, a negative angle occurs.After flange was accomplished, upper bolster 1 lifted, and drive division 5 breaks away from rotating part 10, and under the effect of backhaul portion 7, rotating part 10 rotations are returned to initial position, are convenient to the taking-up of stamping parts 3.In entire work process, along with the rotation of rotating part 10, arc shaped slider 9 rotation arc supporting seat 8 in simultaneously, arc supporting seat 8 provides support for rotating part 10, has prevented that rotating part 10 is out of shape in the punching course.
Though the present invention combines above embodiment to describe; But the present invention is not limited to the foregoing description; And only receiving the qualification of claim, those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present invention and scope.
