Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the application.

[0027] As shown in Figures 1 to 10 A device for quickly positioning the cutters after flat wire grinding, comprising a driving electric cylinder 1, an electric cylinder support 2, a structural bottom plate 3, one end of the electric cylinder support 2 is connected with the driving electric cylinder 1, the other end of the electric cylinder support 2 is connected with the structural bottom plate 3, the output end of the driving electric cylinder 1 is provided with an upper cutter assembly for cutting flat wire, the structural bottom plate 3 is provided with a lower cutter assembly for cooperating with the upper cutter assembly to cut flat wire, further comprising a jacking adjusting mechanism for jacking the lower cutter assembly, the jacking adjusting mechanism comprises a jacking bottom plate 10, a lifting guide bottom plate 11, an adjusting shaft assembly, an intermediate transmission assembly, a jacking assembly, a threaded seat 12, a support column 13, the lifting guide bottom plate 11 is connected with the structural bottom plate 3, one end of the support column 13 is connected with the jacking bottom plate 10, the other end of the support column 13 passes through the lifting guide bottom plate 11 and is connected with the structural bottom plate 3, the adjusting shaft assembly passes through the jacking bottom plate 10 and cooperates with the intermediate transmission assembly, the intermediate transmission assembly is rotatably arranged on the jacking bottom plate 10, the intermediate transmission assembly further cooperates with the jacking assembly, the jacking assembly passes through the jacking bottom plate 10 and threadedly cooperates with the threaded seat 12, the threaded seat 12 is connected with the lifting guide bottom plate 11, the electric cylinder support 2 is further provided with an adjusting limiting block 60, the adjusting limiting block 60 cooperates with the lower cutter assembly.

[0028] Specifically, the adjusting shaft assembly comprises a hand wheel 70, a hand wheel shaft 71, a hand wheel shaft sleeve 72 and a first gear 73, the hand wheel shaft sleeve 72 is installed on the jacking bottom plate 10, the hand wheel 70 is connected with one end of the hand wheel shaft 71, the other end of the hand wheel shaft 71 passes through the hand wheel shaft sleeve 72 and is connected with the first gear 73.

[0029] Specifically, the intermediate transmission assembly comprises a bearing seat 80, an intermediate shaft 81 and a second gear 82, the bearing seat 80 is arranged on the jacking bottom plate 10, one end of the intermediate shaft 81 cooperates with the shaft hole of the bearing seat 80, the other end of the intermediate shaft 81 is connected with the second gear 82, the first gear 73 is engaged with the second gear 82.

Since the second gear 82 and the first gear 73 are in a constant engagement state, the second gear 82 and the intermediate shaft 81 are driven to rotate under the bearing action of the bearing seat 80. Since the second gear 82 and the third gear 90 are in a constant engagement state, the second gear 82 drives the third gear 90 to rotate, and the third gear 90 drives the jacking shaft 91 to upwardly jack the threaded seat 12, so as to upwardly jack the entire lower knife assembly, and finally shorten the distance between the lower knife assembly and the upper knife assembly, so that the upper knife assembly and the lower knife assembly meet the requirement of the flat wire cutting. The support column 13 mainly plays a connecting role and a guiding role in the debugging process. When the jacking adjusting mechanism adjusts the lower knife assembly to contact the adjusting limiting block 60 on the electric cylinder support 2, it means that the upper knife assembly reaches the maximum range of grinding and cannot be used again.

[0032] The distance between the upper knife assembly and the lower knife assembly is adjusted by the whole jacking adjusting mechanism, and the debugging method is simple. Meanwhile, the defect that the upper knife assembly cannot be accurately positioned after the grinding is compensated, and the range of the grinding of the upper knife assembly is larger through the jacking adjusting mechanism, so that the use frequency of the tool of the upper knife assembly is greatly improved, and the manufacturing cost is reduced.

[0038] Specifically, the compression component 35 further comprises a lock head 35-4, the lock head 35-4 is connected with the guide column 35-2, the lock head 35-4 can limit the clamping plate 31 from falling off the guide column 35-2, when the driving electric cylinder 1 drives the floating hanging block 30 to move downwards, the compression component 35 and the clamping plate 31, the clamping block 32, the punch knife 33 and the pressure ring 34 move downwards at the same time, when the pressing ring 35-1 contacts the flat wire, the driving electric cylinder 1 continuously applies driving force downwards, the rectangular spring 35-3 is gradually compressed, and with the gradual compression of the rectangular spring 35-3, the rectangular spring 35 also applies pressure to the pressure ring 34, so that the pressure ring 34 presses the flat wire on the concave die 20, to prevent the flat wire from deviating in the cutting process, with the driving electric cylinder 1 continuing to apply driving force downwards, the punch knife 33 contacts the flat wire, and finally the flat wire is cut off under the action of the punch knife 33 and the concave die 20.

[0039] The concave die 20 is provided with a first clearance hole 20-1 and a second clearance hole 20-2, the punch 33 is movably connected with the first clearance hole 20-1 and the second clearance hole 20-2, the concave die seat 21 is provided with a third clearance hole 21-1, the third clearance hole 21-1 is communicated with the first clearance hole 20-1 and the second clearance hole 20-2, the concave die bottom plate 22 is provided with a waste conveying inclined hole 22-1, the waste conveying inclined hole 22-1 is communicated with the third clearance hole 21-1, the lifting guide bottom plate 11 is provided with a trapezoidal hole 11-1 and a hopper 11-2 fixedly connected with the lifting guide bottom plate 11, the trapezoidal hole 11-1 is communicated with the waste conveying inclined hole 22-1, the hopper 11-2 is communicated with the trapezoidal hole 11-1, and the third clearance hole 21-1, the waste conveying inclined hole 22-1, the trapezoidal hole 11-1 and the hopper 11-2 form a waste conveying channel.

[0040] Specifically, when the punch 33 cuts the flat wire, the punch 33 moves downward along the first clearance hole 20-1 and the second clearance hole 20-2 on the concave die 20, and metal residues and enameled wire residues are generated during the cutting process, which can be conveyed to the outside of the lower knife assembly along the waste conveying channel formed by the third clearance hole 21-1, the waste conveying inclined hole 22-1, the trapezoidal hole 11-1 and the hopper 11-2 (a metal residue and enameled wire residue recovery bag can be arranged at the hopper 11-2, so that the metal residue and enameled wire residue flow into the recovery bag), thereby avoiding the accumulation of the metal residue and enameled wire residue on the lower knife assembly and affecting the cutting quality of the flat wire.

[0041] The punch 33 includes a first punch head 33-1 and a second punch head 33-2, and the first punch head 33-1 and the second punch head 33-2 are connected to form a cutting edge 33-3, the first punch head 33-1 is longer than the second punch head 33-2, the first punch head 33-1 is movably connected with the first clearance hole 20-1, and the second punch head 33-2 is movably connected with the second clearance hole 20-2.

[0043] The first circular platform 40 and the second circular platform 41 are staggered on the axial end surface of the concave die 20, and the heights of the first circular platform 40 and the second circular platform 41 are the same, and the thickness of the flat wire is greater than the height of the first circular platform 40 and the second circular platform 41.

[0044] Specifically, when the flat wire is contacted by the pressure ring 34 on the concave die 20, in order to prevent the flat wire from being pressed and deformed, the first circular platform 40 and the second circular platform 41 are staggered on the concave die 20, and the height of the first circular platform 40 and the second circular platform 41 is slightly less than the thickness of the flat wire (for example, the thickness of the flat wire is 2.00 mm, and the height of the first circular platform 40 and the second circular platform 41 should be in the range of 1.85-1.95 mm), so that even if the pressure ring 34 is pressed on the flat wire, the flat wire will not be directly pressed and deformed, and at the same time, the pressure ring 34 also plays a positioning role on the flat wire.
