The purpose of the utility model and solve its technical problem and adopt following technical scheme to realize.A kind of round pin that proposes according to the utility model is towards flat punch die; Comprise base; Said base is provided with cylinder, movable end and clamp mechanism; Be connected with tool rest mechanism on the said movable end, said tool rest mechanism is used for stamping-out and is fixed on the round pin on this clamp mechanism, and said cylinder is used to provide power to said tool rest mechanism.
Aforesaid round pin is towards flat punch die; Wherein said tool rest mechanism comprises the upper cutter head base; Be fixed on the upper cutter head on this upper cutter head base, be fixed with the upper punch of belt blade head on the said upper cutter head, said upper cutter head base and movable end flexibly connect; During work, said cylinder drives upper punch and moves downward the stamping-out round pin.
Aforesaid round pin is towards flat punch die, and wherein said clamp mechanism comprises dovetail and the dovetail mount that is fixed on the base, and an end of said dovetail mount is provided with the movable end gliding groove.
Aforesaid round pin is towards flat punch die, and wherein said tool rest mechanism is connected through horizontal backstop with said clamp mechanism, and said horizontal backstop is arranged in the gliding groove, and during work, said horizontal backstop moves up and down in said gliding groove.
Aforesaid round pin is towards flat punch die, and wherein said cutter head is movably connected on the said upper cutter head.
Aforesaid round pin is towards flat punch die, and corresponding said movable end gliding groove is provided with chute on the wherein said base, and said chute is a plurality of.
By technique scheme, the utility model round pin has advantage at least towards flat punch die:
The round pin of the utility model adopts tool rest mechanism, clamp mechanism and cylinder to cooperatively interact towards flat punch die and accomplishes the work of round pin punching; High efficiency; Through offset the expansive force of tool rest mechanism when the stamping-out round pin by horizontal backstop; Keep the indeformable or deflection of round pin little, the protection cylinder does not receive the external force effect.
In sum, the round pin of the utility model special construction improves clamping mode towards flat punch die, enhances productivity.It has above-mentioned many advantages and practical value, and in like product, does not see have similar structural design to publish or use and really belong to innovation, no matter it structurally or bigger improvement all arranged on the function; Have large improvement technically; And produced handy and practical effect, and clamp round pin than existing manual screw-threaded coupling, go out the mode in flat hole by punch press; Multinomial effect with enhancement; Thereby being suitable for practicality more, and having the extensive value of industry, really is the new design of a novelty, progress, practicality.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the structural representation of the described round pin of the utility model towards flat punch die.
Among the 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.
The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment; To the round pin that proposes according to the utility model towards its specific embodiment of flat punch die, structure, characteristic and effect thereof, specify as after.
See also shown in Figure 1; The round pin of the utility model preferred embodiment comprises base 9 towards flat punch die, and base 9 is provided with cylinder 6, movable end and clamp mechanism; Be connected with tool rest mechanism on the movable end, tool rest mechanism is used for stamping-out and is fixed on the round pin on this clamp mechanism.
The tool rest mechanism of the utility model comprises upper cutter head base 8; Be fixed on the upper cutter head 11 on this upper cutter head base 8; Be fixed with the upper punch 15 of belt blade head 18 on the upper cutter head 11; Upper cutter head base 8 flexibly connects with movable end, and during work, cylinder 6 is installed on the cylinder holder 12 and drives upper punch 15 and move downward the stamping-out round pin along chute 3.
The clamp mechanism of the utility model comprises the dovetail 2 and dovetail mount 1 that is fixed on the base 9; One end of dovetail mount 1 is provided with movable end gliding groove 4; Tool rest mechanism is connected through horizontal backstop 10 with said clamp mechanism; Laterally backstop 10 is arranged in the movable end gliding groove 4, and during work, laterally backstop 10 moves up and down in movable end gliding groove 4.Corresponding movable end gliding groove 4 is provided with chute 3 on the base 9, and chute 3 is a plurality of.
The utility model clamp mechanism course of work is following: after each structure connects completion, and according to different round pin length and diameters, the diameter and the round pin location dimension of adjustment core rod 16; Promote reversal valve, cylinder 6 moves left, drives dovetail 2; Make moulds open, the round pin afterbody that heats is put into core rod 16 with round pin mount pad location, and reversal valve resets; Cylinder 6 moves to the right, clamps round pin; Step on foot's control pedal, forcing press upper punch 15 beginnings action downwards drives cutter head 18 downward stamping-out round pins; This moment, laterally backstop 10 moved downward with upper punch 15; Laterally backstop 10 is longer than upper punch 15, gets in advance in dovetail 2 square holes and props up sliding end, when upper punch 15 touches round pin and beginning stamping-out square hole; Left expansive force when laterally backstop 10 is offset because of stamping-out; Thereby 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 receive the external force effect simultaneously.Then lathe continues action, and cutter head 18 leaves round pin, waits lathe upper punch 15 to move to promote reversal valve once more after upper to make cylinder 6 move left, opens mould and takes out workpiece, carries out the stamping-out of next round, so circulates.When needing the square hole of stamping-out different size, pull down the press strip of dovetail 2, the core rod 16 of the diameter that replacing needs, and the location of adjustment round pin carry out the stamping-out of square hole.
The utility model round pin that above-mentioned structure like this constitutes all has many saving graces towards the technological innovation of flat punch die for technical staff of the same trade now, and the progressive that possesses skills really.
The above; It only is the preferred embodiment of the utility model; Not being that the utility model is done any pro forma restriction, though the utility model with the preferred embodiment exposure as above, yet is not in order to limit the utility model; Anyly be familiar with the professional and technical personnel; In not breaking away from the utility model technical scheme scope, make a little change or be modified to the equivalent embodiment of equivalent variations when the technology contents of above-mentioned announcement capable of using, be the content that does not break away from the utility model technical scheme in every case;, all still belong in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
