In figure: 1, upper mold 2, lower die 3, upper punch box for needle or pin body 301, upper public plate 302, upper public 303, thimble slot 4, stripper 5,
First elastic component 6, the lower edge of a knife 7, public slot 8, thimble 9, through-hole 10, column 11, support plate 1101, aperture 12, die pad 13, the
Two elastic components 14, guide post 15, positioning pin 16, die shank 17, bottom plate.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is further described.
Referring to FIG. 1, embodiment of the invention discloses a kind of clamp oval gasket sawing sheet mold, including upper mold 1 is under
Mould 2, the upper mold 1 include upper punch box for needle or pin body 3 and stripper 4, and the upper punch box for needle or pin body 3 includes upper public plate 301 and upper public affairs
302, it is upper public affairs plate 301 at the top of be equipped with die shank 16, for connecting power mechanism, such as diesel engine, for providing power for upper mold 1, institute
It states public 302 top vertical and is set to 301 bottom center of upper public plate, bottom center is equipped with a thimble slot 303, the lower die 2
Including bottom plate 17 and the lower edge of a knife 6, the lower edge of a knife 6 is installed at 17 top center of bottom plate, between the bottom plate 17 and the lower edge of a knife 6
Equipped at least two positioning pins 15, for realizing the fixed installation between the lower edge of a knife 6 and bottom plate 17, set in the middle part of the lower edge of a knife 6
Having and matches and perforative public slot 7 up and down with upper public 302, i.e., the cross section of public slot 7 is identical as upper public 302 cross-sectional shape, and
When being the shape of clamp oval gasket to be processed, therefore flitch being placed on lower 6 position of the edge of a knife, upper public 302 are moved downward
When pushing flitch, the cleavable flitch of the edge of a knife of lower 6 upper edge of the edge of a knife completes the sawing sheet of clamp oval gasket.
17 center vertical of bottom plate is equipped with a thimble 8, and the thimble 8 is located in public slot 7 and matches with thimble slot 303,
Generally, the internal diameter of the thimble slot 303 is greater than the outer diameter of the thimble 8, and the height of the thimble slot 303 is greater than the top
The length of needle 8, for the oval gasket after sawing sheet when continuing on public 7 inner wall of slot and moving downward, the thimble 8 can be right as a result,
The process that oval gasket completes punching, thimble 8 are entered to together with the material after punching in thimble slot 303, and then one downward
Punching press movement two operational sequences of sawing sheet and punching press may be implemented；While in order to guarantee going on smoothly for punching press, the upper mold
1 and lower die 2 need to be completely corresponded up and down placement, guarantee that described public 302, public slot 7, thimble 8 and the central axis of thimble slot 303 are equal
It is located along the same line.
The stripper 4 is set in public 302 outer wall, and can slide up and down along upper public 302 outer wall, the stripper 4 with
It is equipped with the first elastic component 5 between upper public affairs plate 301, for pushing down on stripper 4, realizes 4 bottom of stripper and upper public 302 bottom
Concordantly；In this way when flitch is by upper public 302 downward die cut, it can be moved upwards along upper public 302 outer wall, and be tightly attached to public affairs
302 outer walls, stripper 4 also will receive external force the first elastic component 5 of compression at this time；Revolution is upward after upper public 302 complete sawing sheet
When movement, the external force of the first elastic component 5 gradually disappears at this time, therefore will push stripper 4 and transport downwards along upper public 302 outer wall
It is dynamic, and then flitch is driven also to move together, until completing the material returned of flitch when 4 bottom of stripper is concordant with upper public 302 bottom.
Further, several through-holes 9 are equipped at intervals on the bottom plate 17 in the public slot 7 etc., in each through-hole 9
An interspersed column 10, several 10 tops of column are installed with support plate 11, the cross section of the support plate 11 and public slot 7 jointly
Shape is identical, and the support plate 11 is equipped with the aperture 1101 to match with thimble 8, and several 10 bottoms of column connect one jointly
Die pad 12, is equipped with the second elastic component 13 between 17 bottom of the die pad 12 and bottom plate, when normal condition, second elastic component
13 push up support plate 11 to the top of thimble 8, at this point, the aperture 1101 is placed exactly in 8 top of thimble, when upper public 302 to
After undershoot pressure plate sawing sheet is at oval gasket, upper public 302 and support plate 11 can clamp oval gasket up and down, and pass through thimble
8, which pass through aperture 1101, completes punching operation, prevents occurring the deformation of oval gasket during punching in this way.Generally, it opens
The sectional area in hole 1101 is slightly larger than the sectional area of thimble 8, guarantees going on smoothly for punching operation；And after punching press completion, the
Two elastic components 13 can be sprung back, and the oval gasket top for completing processing is got on, stripper 4 can also be pushed manually to continue up top
Out, it is directly taken out convenient for operator.
Further, 4 edge of stripper is interspersed with several guide posts 14 at equal intervals, and 14 top of guide post is fixedly arranged on
In public plate 301, bottom end is extended through to the lower section of stripper 4, and flitch can also open up and guide post in processing in relevant position
The corresponding circular hole in 14 positions prevents flitch from shifting thus during punching press, influences sawing sheet quality.
It is described in the present invention that specific embodiments are merely illustrative of the spirit of the present invention.Technology belonging to the present invention
The technical staff in field can make various modifications or additions to the described embodiments or by a similar method
Substitution, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
In the absence of conflict, the feature in embodiment and embodiment herein-above set forth can be combined with each other.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
