Description
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of two-way floating punching die.
Background technology
Usually need the different parts of some shape thickness of large batch of processing in production process, for enhancing productivity, need to develop different moulds.If a kind of pipe of production and processing, this pipe diameter is less, wall thickness thinner and on tube wall more die-cut apertures be greater than the aperture of wall thickness, for this kind of pipe fitting, if adopt general punching die, because the formation of punching is longer, punch is more easily lost, mould easily damages, and also easily distortion of the pipe fitting punching position of producing.Therefore, need to develop a kind of new mould to meet the pipe fitting of producing this situation.
Summary of the invention
goal of the invention: purpose of the present invention just is to provide a kind of two-way floating punching die.
technical scheme:for achieving the above object, the present invention has taked following technical scheme:
A kind of two-way floating punching die, it is characterized in that: described mould is by upper and lower two groups of identical module compositions, described upper module comprises upper bolster, described upper bolster is provided with upper mounted plate, be equipped with punch and punch fastening assembly in the fixed plate, the punch fastening assembly comprises positioning sleeve, punch fixed cover and trip bolt, described punch is fixed on described positioning sleeve and together is installed in described punch fixed cover with described positioning sleeve, and fastening by described trip bolt, described punch fixed cover below is provided with the punch guide pin bushing, the described punch guide pin bushing outside is provided with stripper, described punch guide pin bushing and stripper are located at the left and right sides, described punch end, the formation of described lower module is identical with upper module and symmetrical up and down, be connected with two groups of large guide pillars and one group of little guide pillar between described upper bolster and die shoe.
Be provided with unloading bolt with the stripper inside of described little guide pillar relative direction, described unloading bolt one end is located at described stripper inside, and the other end is located at the inside of described die shoe or die shoe, and fixes by fastening bolt.
The end of described punch is inclined-plane, and angle of inclination is 35-45 °.
Be provided with spring between described stripper and upper and lower fixing plate, described spring is located at a side of described unloading bolt.
Described large guide column sleeve has large guide pin bushing, and described little guide column sleeve has little guide pin bushing.
beneficial effect:adopt the present invention of technique scheme to have the following advantages:
Two-way floating punching die of the present invention, by upper and lower two groups of identical modules, formed, the symmetry of mould is good, the pipe fitting of producing is not yielding, and only comprise punch, there is no die, Design of Dies is simple, also be provided with the punch fastening assembly around punch simultaneously, the good like this punch of having protected, make punch be difficult for losing, extended the service life of mould, also improved the non-deformability of pipe fitting simultaneously, improve punching quality, guider of the present invention has been set up again little guide pillar on the basis of large guide pillar simultaneously, thereby guaranteed the punch clearance of mould, improved punching quality, improved greatly production efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-die shoe, 2-bottom plate, the large guide pillar of 3-, the little guide pillar of 4-, the little guide pin bushing of 5-, 6-pipe fitting, the large guide pin bushing of 7-, 8-upper mounted plate, 9-punch fixed cover, 10-upper bolster, 11-die shank, 12-trip bolt, 13-positioning sleeve, 14-fastening bolt, 15-punch, 16-unloading bolt, 17-stripper, 18-spring, 19-punch guide pin bushing.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further set forth.
As shown in the figure: a kind of two-way floating punching die of the present invention, it is characterized in that: described mould is by upper and lower two groups of identical module compositions, described upper module comprises upper bolster 10, described upper bolster 10 is provided with upper mounted plate 8, be equipped with punch 15 and punch fastening assembly in fixed plate 8, the punch fastening assembly comprises positioning sleeve 13, punch fixed cover 9 and trip bolt 12, described punch 15 is fixed on described positioning sleeve 13 and together is installed in described punch fixed cover 9 with described positioning sleeve 13, and fastening by described trip bolt 12, described punch fixed cover 9 belows are provided with punch guide pin bushing 19, described punch guide pin bushing 19 outsides are provided with stripper 17, described punch guide pin bushing 19 and stripper 17 are located at described punch 15 left and right sides, end, the formation of described lower module is identical with upper module and symmetrical up and down, be connected with two groups of large guide pillars 3 and one group little guide pillar 4 between described upper bolster 10 and die shoe 1, be provided with unloading bolt 16 with stripper 17 inside of described little guide pillar 4 relative directions, described unloading bolt 16 1 ends are located at described stripper 17 inside, the other end is located at the inside of described die shoe 10 or die shoe 1, and fixing by fastening bolt 14, the end of described punch 15 is inclined-plane, angle of inclination is 35-45 ° preferably, described stripper 17 is with upper, bottom plate 8, be provided with spring 18 between 2, described spring 18 is located at a side of described unloading bolt 16.
