Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of dual-guiding structure be applied on multi-station progressive die of the utility model as shown in Figure 1, there is the first guiding mechanism and the second guiding mechanism, what the first guiding mechanism adopted is the guide frame of the large guide pin bushing of large guide pillar and accurate roller guiding form, guide frame and the accurate roller guiding form of what the second guiding mechanism adopted the is little guide pin bushing of little guide pillar, first guiding mechanism comprises primarily of upper bolster 2, for connecting the large guide pillar 9 of upper bolster 2 and die shoe 15, to be arranged in upper bolster 2 and the part of the upper die that forms of the large guide pillar boatswain chair 1 being positioned at large guide pillar 9 top and the large guide pin bushing 3 of patrix that is sleeved on large guide pillar 9 top and primarily of die shoe 15, to be arranged in die shoe 15 and the big spring 13 be positioned at bottom large guide pillar 9, the large guide pin bushing of counterdie 12 being sleeved on large guide pillar 9 bottom and the part of the lower die keeping circle 11 to form greatly between large guide pillar 9 and the large guide pin bushing 12 of counterdie, second guiding mechanism comprises primarily of upper bolster 2, be arranged on the little guide pillar 20 on the shedding mechanism that is made up of discharging fixed head 6 and stripper 21, to be arranged in upper bolster 2 and to be positioned at the patrix little spring 26 at little guide pillar 20 top, be sleeved on part of the upper die that the little guide pin bushing of patrix 24 on little guide pillar 20 top and the little maintenance circle 25 of patrix between little guide pillar 20 and the little guide pin bushing of patrix 24 form and primarily of die shoe 15, to be arranged in die shoe 15 and the counterdie little spring 16 be positioned at bottom little guide pillar 20, be sleeved on the part of the lower die that the little guide pin bushing of counterdie 17 of little guide pillar 20 bottom and the little maintenance circle 18 of counterdie between little guide pillar 20 and the little guide pin bushing of counterdie 17 form.
The quantity of the first guiding mechanism is at least four, when high velocity ram machine is when carrying out punching press, first guiding mechanism is the agent structure of mould, ensure multi-station progressive die patrix and counterdie relative position correct when high speed stamping, its guiding accuracy ensures by the ball on the large maintenance circle 11 between large guide pillar 9 and the large guide pin bushing of counterdie 12, ball on large maintenance circle 11 and the large magnitude of interference having 0.01 ~ 0.02mm between guide pillar 9 and the large guide pin bushing 12 of counterdie, multi-station progressive die patrix under the effect of high-speed punching pressure is made to make PURE ROLLING along large guide pillar about 9, because rolling guiding is gapless, belong to the point cantact motion of ball, so rolling guiding to have precision high, die life long feature.
The quantity of the second guiding mechanism is at least four, the design feature of second guiding mechanism is that little guide pillar 20 is arranged on device for discharging, accurate roller guiding is carried out by the patrix little maintenance circle 25 between little guide pillar 20 and the little guide pin bushing of patrix 24 and the counterdie little maintenance circle 18 between little guide pillar 20 and the little guide pin bushing of counterdie 17, the correctness of the device for discharging on guarantee multi-station progressive die and the relative position of upper bolster 2 and die shoe 15, guide all punch part proper exercises on multi-station progressive die, ensure that between high speed stamping process convex mould and die, relative position is reasonable, gap uniformity, this assures the requirement of multi-station progressive die precision stamping precision.
On multi-station progressive die, adopt dual-guiding structure, namely between the upper bolster 2 and die shoe 15 of mould, the overall punching precision of mould is ensured with the large guide pin bushing of the large guide pillar of precise ball formula, then between device for discharging and upper bolster 2, die shoe 15, the correct of position between device for discharging on mould and upper bolster 2, die shoe 15 is ensured again with the little guide pin bushing of the little guide pillar of precise ball formula, because device for discharging play the guiding role, ensure that reasonable, the gap uniformity of relative position between punch in high speed stamping process on mould and die.
Two guidance method of a kind of dual-guiding structure be applied on multi-station progressive die of the utility model is as follows: the first guiding mechanism is mold integral guiding, by the part of the upper die be made up of upper bolster 2, the large guide pin bushing 3 of patrix, large guide pillar 9, large guide pillar boatswain chair 1, under the effect of high-speed punching pressure, part of the upper die is made accurate roller along large guide pillar about 9 and is moved; Large guide pillar 9 end portion makes upper and lower accurate roller forms of motion, by what keep greatly the large guide pin bushing 12 of circle 11, counterdie, big spring 13 and die shoe 15 to form in part of the lower die carrying out moving, the form of precise ball formula motion is adopted because large guide pillar 9 moves up and down, i.e. ball-type guiding, this assures the correctness of relative position between patrix and counterdie, belong to the precision guiding of mould.
Second guiding mechanism is the device for discharging guiding on multi-station progressive die, upper and lower accurate roller motion is done by being arranged on little guide pillar 20 on device for discharging when high speed stamping, little guide pillar 20 upper part with by the little maintenance circle 25 of patrix, the little guide pin bushing 24 of patrix, accurate roller motion is carried out in the part of the upper die that patrix little spring 26 and upper bolster 2 form, little guide pillar 20 end portion with by the little maintenance circle 18 of counterdie, the little guide pin bushing 17 of counterdie, counterdie little spring 16 and die shoe 15 form part of the lower die and carry out accurate roller motion, same little guide pillar moves up and down and adopts precise ball formula forms of motion, i.e. ball-type guiding, guarantee the device for discharging on multi-station progressive die and upper bolster 2, relative position between die shoe 15 is correct, because device for discharging play the guiding role, guide the proper exercise of all punch parts on multi-station progressive die, between guarantee high speed stamping process convex mould and die, relative position is reasonable, gap uniformity, ensure that the punching precision requirement of multi-station progressive die.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
