Description
Technical field
The invention belongs to field of machining, and in particular to a kind of punching press positioning tool.
Background technique
Punch forming is a kind of common mechanical processing technique, is mainly used for the processing of thin-wall part.Common punching press tooling
It include mainly punch-pin and cavity plate, punch-pin is placed in machine table, and cavity plate is mounted on press machine, when processing, by workpiece to be processed
It is placed on punch-pin, it is mobile to punch-pin then to drive cavity plate by press machine, so that workpiece to be processed is squeezed by punch-pin and cavity plate,
To obtain molding stamped workpieces.
However, punching course is all punching press of the cavity plate in the punch-pin of horizontal direction progress vertical direction, it cannot be to level
The workpieces processing in direction directly carries out horizontal punching press.In workpieces processing is processed or installed, when needing workpieces processing
Rod end surface shape is cambered when requiring, and is difficult to carry out the arc-shaped contact surface of punching press to the end face of bar, for directly to be processed
Workpiece carries out same plane and carries out in punching course, and followed by metal fragment is deposited near stamping parts after the completion of punching press, Yi Ying
Ring completion quality when punching press stamping device next time.
Summary of the invention
In view of the shortcomings of the prior art, the purpose of the present invention is to provide a kind of end face punching press cambers by workpiece to contact
The punching press positioning tool in face.
In order to solve the above technical problems, base case of the present invention is as follows:
Punching press positioning tool, including upper die and lower die, upper mold top are equipped with the cylinder for lifting, and the upper mold is under
Mould is equipped with the sliding slot of section semicircular in shape and places the processing groove of workpiece, and the sliding slot of the lower die is sliding combined with punching press
Bar, processing groove and sliding slot are in arranged crosswise.
The working principle of the invention and advantage are:
1. after upper mold engage with lower die using cylinder, when punch rod moves in sliding slot, due to process groove and
Sliding slot is in arranged crosswise, and using the cross sectional shape of punch rod, punch rod is disconnected simultaneously by the workpiece part punching press for stretching out processing groove
The contact face of workpiece is set to form the contact surface of arc.
2. after upper mold engages with lower die, processing groove defines workpiece by the way that workpiece to be placed in processing groove
Relative displacement occurs in slot in punching course, and then workpiece can be made to keep standard size for a long time, avoids
Workpiece, there is a phenomenon where springing back, causes the processing dimension of stamped workpieces that cannot ensure in punching course.
3, workpiece is fixed by the processing groove formed after being engaged using lower die with upper mold, is improved in punching course
Precision, while after engage upper mold with lower die using cylinder, by the arranged crosswise of processing groove and sliding slot, in processing groove
Workpiece is in the case where stamping device drives punch rod to carry out transverse stamping to it, using the cross sectional shape of punch rod, by workpiece
The contact surface of contact face punching press camber.
Further, fixed plate being installed at the top of the upper mold, the piston rod free end of cylinder is fixedly connected in fixed plate,
It is communicated with escape pipe on cylinder, the gas outlet of escape pipe is towards lower die；Drive upper mold upwards under by cylinder after the completion of punching press
In mould separation process, the gas in cylinder carries out cooling processing by the connecting rod that escape pipe can not only complete rigid punching press,
Fast and easy takes out the connecting rod that punching press is completed, and can also blow off the metal fragment that punching course generates lower die.
Further, the sliding slot is arranged symmetrically along the central axes of upper die and lower die with processing groove；By in central axes
Two sides be provided with sliding slot and processing groove, each punching press can carry out punching press while two pieces workpiece, improve punching press effect
Rate.
Further, the end face of the lower die is equipped with several positioning grooves, and the bottom of upper mold is equipped with several protrusions, raised position
In the surface of positioning groove；In the snap-fitting process of upper mold and lower die, upper mold can be improved by setting protrusion and positioning groove
Engaging precision with lower die, and the phenomenon that prevent workpiece from deviating in punching course.
Further, the positioning groove is located at four edges of lower die, and protrusion is located at four edges of upper mold；Pass through
By positioning groove and protrusion setting four and four edges for being located at lower die and upper mold, upper mold and lower die are not only increased
The overall stability of engaging also will not influence the use function of upper mold and lower die.
Further, the hemispherical shape of protrusion, corresponding positioning groove also hemispherical shape；Being set as semi-spherical shape can
To absorb a part of error in installation process in upper mold and lower die snap-fitting process, upper mold and lower die snap-fitting process are avoided the occurrence of
It is middle the phenomenon that engaging completely occur because of subtle machine error, at the same upper mold with engage after will not influence its engaging essence
Degree.
