The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in the figure, a kind of coiling machine cutter that the utility model discloses comprises two-way cutter mechanism and transmission mechanism, and the slide block 11 in the two-way cutter mechanism is fixedly connected with screw mandrel 2 in the transmission mechanism.
Two-way cutter mechanism comprises slide block 11, slide 10, core cutter 141, core tool rest 14, upper cutter 121 and lower cutter 131, upper cutter seat 12 and incision tool rest 13; Wherein upper cutter 121 is arranged on the upper cutter seat 12, upper cutter seat 12 is installed on the slide block 11, same, lower cutter 131 is arranged on the incision tool rest 13, incision tool rest 13 peaces also are contained on the slide block 11, be that upper cutter seat 12 and incision tool rest 13 all are arranged on the same slide block 11, slide block 11 slidably is installed in the slide 10, and the blade of upper cutter 121 and lower cutter 131 arranges in opposite directions; Described core cutter 141 is between the blade of upper cutter 121 and lower cutter 131, and core cutter 141 is installed on the core tool rest 14, and the bottom surface of incision tool rest 13 also is provided with incision tool rest stake 132, is used for supporting lower cutter 131.
Respectively be provided with two set screw 15 on upper cutter seat 12 and the incision tool rest 13, an end of set screw 15 is conflicted on cutting knife; Also be provided with cutting knife pad 16 between cutting knife and the slide block 11, cutting knife pad 16 is arc with the contact-making surface of cutting knife, and when turning set screw 15, set screw 15 promotes cutting knife, can regulate cutting knife with respect to distance and the angle of slide block 11.
Described transmission mechanism comprises screw mandrel 2, nut frame 21, and nose cone 22, trimmer 23, taper roll bearing 24 all carries cover 25; Described screw mandrel 2 is arranged in the nut frame 21, offer the installing hole 27 that several install nose cone 22 and taper roll bearing 24 on the nut frame 21, one end of described nose cone 22 is fastened between the screw thread of screw mandrel 2, the other end is arranged in the taper roll bearing 24, the shape of nose cone 22 meets the depression between screw mandrel 2 screw threads just, the stressed synthetic power of the taper seat of nose cone 22 and screw mandrel 2 axis angle b, with taper roll bearing 24 inner ring inner surfaces and screw mandrel 2 axial line angle a, their relation satisfies 1.25tga≤tgb≤1.7tga, when guaranteeing that taper roll bearing 24 rolls, nose cone 22 stand under load over half has at least improved bearing capacity and transmission accuracy.
Nut frame 21 is outside equipped with and all carries cover 25, be provided with trimmer 23 in the installing hole 27, trimmer 23 is in and all carries between cover 25 and the nose cone 22, carry all that cover 25 closes trimmer 23 so that all nose cones 22 are stressed evenly, improved the transmission accuracy of screw mandrel 2, and screw mandrel 2 also is provided with a muscle 26 along the middle of groove, has improved the transmission efficiency of 22 pairs of screw mandrels 2 of nose cone, the vibration amplitude that nose cone 22 produces when having reduced transmission.
Operation principle of the present utility model is:
Gear driven nut frame 21 rotates, and the nose cone 22 that is arranged in the installing hole 27 rotates thereupon, carries out rectilinear motion thereby promote screw mandrel 2.
When coiling machine need to cut off the dextrorotation spring, regulate core tool rest 14 near upper cutter seat 12, thereby so that core cutter 141 close upper cutters 121, steel wire enters beginning dextrorotation from core cutter 141 upsides, when the length of spring 17 arrives preseting length, under the effect of screw mandrel 2, slide block 11 moves down in slide 10, and drive upper cutter seat 12 and move down, thereby so that upper cutter 121 cuts off the dextrorotation spring, cut off spring 17 rear sliders 11 and upwards reset, enter the circulation of next round.Because this moment, core cutter 141 was near upper cutter 121, so the lower cutter 131 that slide block 11 drives can't have influence on spring 17.
In like manner, when coiling machine need to cut off left-handed spring, regulate core tool rest 14 near incision tool rest 13, thereby so that core cutter 141 close lower cutters 131, it is left-handed that steel wire enters beginning from the downside of core cutter 141, when the length of spring 17 arrived preseting length, under the effect of screw mandrel 2, slide block 11 moved up in slide 10, driving incision tool rest 13 moves up, thereby so that lower cutter 131 cuts off left-handed spring, cut off spring 17 rear sliders 11 and reset downwards, enter the circulation of next round.Because this moment, core cutter 141 was near lower cutter 131, so the upper cutter 121 that slide block 11 drives can not have influence on spring 17 yet.
By such scheme, realized that a cover cutter mechanism cuts off the purpose of two kinds of different springs 17, simple in structure, reduced manufacturing cost.
Above-mentioned only is specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
