The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of round pin proposed according to the present invention rushes flat punch die, comprise base, described base is provided with cylinder, movable end gliding groove and clamp system, on described movable end gliding groove, activity is plugged with knife holder mechanism, described knife holder mechanism is fixed on the round pin on this clamp system for stamping-out, and described cylinder is used for supplying power to described knife holder mechanism.
Aforesaid round pin rushes flat punch die, wherein said knife holder mechanism comprises upper cutter head base, be fixed on the upper cutter head on this upper cutter head base, described upper cutter head is fixed with the upper punch of belt blade head, described upper cutter head base and movable end gliding groove plug, during work, described cylinder drives upper punch to move downward stamping-out round pin.
Aforesaid round pin rushes flat punch die, and wherein said clamp system comprises dovetail mount and is arranged on the dovetail on dovetail mount, one end of described dovetail mount is provided with movable end gliding groove.
aforesaid round pin rushes flat punch die, and wherein said knife holder mechanism is connected by horizontal backstop with described clamp system, and described horizontal backstop is arranged in movable end gliding groove, and during work, described horizontal backstop moves up and down in described movable end gliding groove.
Aforesaid round pin rushes flat punch die, and wherein said cutter head is movably connected on described upper cutter head.
Aforesaid round pin rushes flat punch die, and on wherein said base, corresponding described movable end gliding groove is provided with chute, and described chute is multiple.
By technique scheme, round pin of the present invention rushes flat punch die and at least has following advantages:
Round pin of the present invention rushes flat punch die and adopts knife holder mechanism, clamp system and cylinder to have cooperatively interacted the work of round pin punching; operating efficiency is high; by offsetting the expansive force of knife holder mechanism when stamping-out round pin by horizontal backstop; keep the indeformable or deflection of round pin little, protection cylinder is not by External Force Acting.
In sum, the round pin of special construction of the present invention rushes flat punch die, improves clamping mode, enhances productivity.It has above-mentioned many advantages and practical value, and publish there are no similar structural design or use in like product and really belong to innovation, no matter it structurally or functionally all has larger improvement, have large improvement technically, and create handy and practical effect, and more existing artificial screw-threaded coupling clamping round pin, the mode in flat hole is gone out by punch press, there is multinomial effect of enhancement, thus be more suitable for practicality, and there is the extensive value of industry, be really a new and innovative, progressive, practical new design.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is the structural representation that round pin of the present invention rushes flat punch die.
In figure: 1, dovetail mount; 2, dovetail; 3, chute; 4, movable end gliding groove; 5, upper punch; 6, cylinder; 8, upper cutter head base; 9, base; 10, horizontal backstop; 11, upper cutter head; 12, cylinder holder; 15, upper punch; 16, core rod; 18, cutter head.
Detailed description of the invention
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, its detailed description of the invention of flat punch die, structure, feature and effect thereof are rushed to the round pin proposed according to the present invention, is described in detail as follows.
Refer to shown in Fig. 1, the round pin of present pre-ferred embodiments rushes flat punch die, comprises base 9, base 9 is provided with cylinder 6, movable end gliding groove 4 and clamp system, on movable end gliding groove 4, activity is plugged with knife holder mechanism, and knife holder mechanism is fixed on the round pin on this clamp system for stamping-out.
Knife holder mechanism of the present invention comprises upper cutter head base 8, be fixed on the upper cutter head 11 on this upper cutter head base 8, upper cutter head 11 is fixed with the upper punch 15 of belt blade head 18, upper cutter head base 8 and movable end gliding groove 4 grafting, during work, cylinder 6 is arranged on 12 drive upper punch 15 on cylinder holder and moves downward stamping-out round pin along chute 3.
The dovetail 2 that clamp system of the present invention comprises dovetail mount 1 and is arranged on dovetail mount 1, one end of dovetail mount 1 is provided with movable end gliding groove 4, knife holder mechanism is connected by horizontal backstop 10 with described clamp system, horizontal backstop 10 is arranged in movable end gliding groove 4, during work, horizontal backstop 10 moves up and down in movable end gliding groove 4.On base 9, corresponding movable end gliding groove 4 is provided with chute 3, and chute 3 is multiple.
The clamp system course of work of the present invention is as follows: after each anatomical connectivity completes, according to different round pin length and diameter, the diameter of adjustment core rod 16 and round pin location dimension, promote reversal valve, cylinder 6 action left, drive dovetail 2, mould is opened, and the round pin afterbody heated puts into core rod 16, reset reversal valve with round pin mount pad location, cylinder 6 action to the right, clamps round pin; Step on foot's control pedal; forcing press upper punch 15 starts downward action; band dynamic cutter head 18 stamping-out round pin downwards; now horizontal backstop 10 moves downward together with upper punch 15; horizontal backstop 10 is longer than upper punch 15; enter in advance in dovetail 2 square hole and prop up sliding end; when upper punch 15 touches round pin and starts stamping-out square hole; horizontal backstop 10 is offset because of expansive force left during stamping-out; thus offset round pin after going out square hole with the distortion of the vertical direction of square hole; keep the indeformable or deflection of round pin very little, also protect cylinder 6 not by External Force Acting simultaneously.Then lathe continues action, and cutter head 18 leaves round pin, wait lathe upper punch 15 move to upper after again promote reversal valve and make cylinder 6 action left, open mould and take out workpiece, carry out the stamping-out of next round, so circulate.In time needing the square hole of stamping-out different size, pull down the press strip of dovetail 2, change the core rod 16 of the diameter needed, and adjust the location of round pin, carry out the stamping-out of square hole.
The round pin of the present invention of above-mentioned Structure composing like this rushes the technological innovation of flat punch die, for technical staff of the same trade now, all have many saving graces, and the progressive that really possesses skills.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
