[0059] Embodiment 1

[0060] As shown in Figures 1-3 A wire feeding and cutting device, which comprises a cutting part 100 for cutting the wire, a feeding part 200 for feeding the wire into the cutting part 100, and a clamping part 300 arranged on the feeding part 200 and matched with the feeding part 200; the feeding part 200 is fixed on the cutting part 100 through a connecting frame 400.

[0061] As shown in Figure 4 , 5 , 10, 11, the cutting part 100 comprises a cutting driving structure 110, a cutting advancing structure 120 connected with the cutting driving structure 110 for completing the cutting process, an adjustable fixing structure 130 arranged on the cutting driving structure 110 and matched with the cutting advancing structure 120 for completing the cutting process, and an upper fixing structure 140 for introducing the wire to be cut.

[0062] The cutting driving structure 110 comprises a vertical fixed plate 111 arranged vertically, a cutting driving hydraulic cylinder 112 arranged on the rear side of the vertical fixed plate 111 and penetrating the vertical fixed plate 111, a horizontal fixed plate 113 arranged horizontally and fixed on the front of the vertical fixed plate 111, and a lower support plate 114 fixed on the vertical fixed plate 111 and the horizontal fixed plate 113 for auxiliary supporting the horizontal fixed plate 113;

[0063] The cutting travel structure 120 comprises a cutting follower 121 arranged on the telescopic rod of the cutting driving hydraulic cylinder 112 and movable forward and backward with the telescopic rod, a cutting dynamic clamping plate 123 arranged between the cutting follower 121 and the horizontal fixed plate 113 and with the front end extending out of the cutting follower 121, a spring 122 horizontally arranged between the cutting follower 121 and the cutting dynamic clamping plate 123, a dynamic clamping plate half-hopper groove 125 vertically arranged at the front end of the cutting dynamic clamping plate 123, and a cutting knife 124 located between the cutting follower 121 and the cutting dynamic clamping plate 123 and fixed on the lower side of the cutting follower 121.

[0064] The adjustable fixing structure 130 comprises a cutting fixed position adjusting hydraulic cylinder 131 arranged at the front end of the horizontal fixed plate 113, an adjusting hydraulic cylinder fixing block 132 for fixing the cutting fixed position adjusting hydraulic cylinder 131 on the horizontal fixed plate 113, a cutting adjustable clamping plate 133 arranged at the rear end of the telescopic rod of the cutting fixed position adjusting hydraulic cylinder 131 and movable forward and backward with the telescopic rod, an adjustable clamping plate half-hopper groove 135 arranged at the front end of the cutting adjustable clamping plate 133 and matched with the dynamic clamping plate half-hopper groove 125, and a cutting knife matching block 134 located above the cutting adjustable clamping plate 133 and arranged on the horizontal fixed plate 113 and matched with the cutting knife 124.

[0065] The adjustment of the position of the adjustable clamping plate half-hopper groove can be achieved by the telescopic rod of the cutting fixed position adjusting hydraulic cylinder, so that it can be better adapted to different production requirements, further improving the application range of the product.

[0066] The upper fixing structure 140 comprises a cutting feed block 141 arranged on the horizontal fixed plate 113, and a cutting feed hopper groove 142 vertically penetrating through the cutting feed block 141.

[0067] The central axis of the cutting feed hopper groove 142 and the central axis of the hopper groove structure formed by assembling the dynamic clamping plate half-hopper groove 125 and the adjustable clamping plate half-hopper groove 135 coincide.

[0068] The working principle of the cutting part is as follows:

[0069] The wire enters the cutting feed hopper groove, and the lower end of the wire travels downward until it exceeds the adjustable clamping plate half-hopper groove. After the cutting instruction is automatically triggered or triggered by the operator, the telescopic rod of the cutting driving hydraulic cylinder pushes the cutting follower forward, and the spring gives the cutting dynamic clamping plate a forward thrust due to compression until the cutting dynamic clamping plate abuts against the cutting adjustable clamping plate. At this time, the cutting follower continues to be pushed forward and continues to drive the cutting knife to travel, and finally the cutting knife cooperates with the cutting knife matching block to complete the cutting of the wire. After cutting, the telescopic rod drives the cutting follower to retreat, so that the cutting knife and the cutting dynamic clamping plate retreat and reset.

[0070] After the cutting dynamic clamping plate abuts against the cutting adjustable clamping plate, even if the cutting follower continues to be pushed forward, the force on the wire clamped between the cutting dynamic clamping plate and the cutting adjustable clamping plate can be reduced by the compression spring, effectively avoiding the deformation of the wire due to excessive clamping force, and better protecting the wire.

[0071] As shown in Figure 6 , 7 , 10, 11, the feeding part 200 comprises a feeding drive structure 210, a feeding follower support structure 230 arranged on the feeding drive structure 210, and a feeding clamping structure 220 arranged on the feeding follower support structure 230.

[0072] The feeding drive structure 210 comprises a vertical track plate 212, a feeding drive hydraulic cylinder 211 arranged on the rear side of the vertical track plate 212 and moving in the vertical direction, a drive block 213 arranged on the telescopic rod of the feeding drive hydraulic cylinder 211, and a driven cross plate 214 arranged on the drive block 213 and penetrating the vertical track plate 212 at the front end; wherein a rectangular window with a size corresponding to the movement range of the driven cross plate 214 is arranged on the vertical track plate 212.

[0073] The feeding follower support structure 230 comprises two vertical guide rails 233 arranged vertically and parallel to each other on the left and right sides of the rectangular window on the front side of the vertical track plate 212, a vertical follower bottom plate 232 erected on the two vertical guide rails 233 and fixed on the front end of the driven cross plate 214 at the rear side, and a follower support frame 231 arranged on the front side of the vertical follower bottom plate 232.

[0074] The feeding clamping structure 220 comprises a feeding clamping drive hydraulic cylinder 221 arranged on the front end of the outside of the follower support frame 231 and penetrating the follower support frame 231 horizontally, a feeding clamping block 222 arranged on the telescopic rod of the feeding clamping drive hydraulic cylinder 221, a feeding upper guide block 224 arranged on the vertical follower bottom plate 232, a feeding lower guide block 223 arranged below the feeding upper guide block 224, a feeding fixed clamping block 227 arranged on the vertical follower bottom plate 232 and between the feeding upper guide block 224 and the feeding lower guide block 223, a feeding upper funnel groove 225 vertically penetrating the feeding upper guide block 224, a feeding lower funnel groove 226 vertically penetrating the feeding lower guide block 223, a feeding fixed half-funnel groove arranged on the front side of the feeding fixed clamping block 227, a feeding clamping I-beam block 228 arranged on the side surface of the feeding clamping block 222 facing the feeding fixed clamping block 227, and a feeding clamping elastic block 229 arranged on the side surface of the feeding clamping I-beam block 228 facing the feeding fixed clamping block 227.

[0075] The middle axes of the upper feeding funnel groove 225, the lower feeding funnel groove 226 and the feeding fixed half funnel groove coincide.

[0076] The working principle of the feeding part is as follows:

[0077] When feeding is needed, the initial position of the extension rod of the feeding drive hydraulic cylinder is high, the wire is inserted into the upper feeding funnel groove and taken out of the lower feeding funnel groove, the extension rod of the feeding clamping drive hydraulic cylinder is extended to drive the feeding clamping block to move, the feeding clamping block moves and pushes the feeding clamping elastic block to press the wire into the feeding fixed half funnel groove of the feeding fixed clamping block, then the extension rod of the feeding drive hydraulic cylinder moves from the high position to the low position to drive the vertical follow-up bottom plate to move downward, and the wire is pulled downward during the movement of the vertical follow-up bottom plate. After the feeding is completed, the extension rod of the feeding clamping drive hydraulic cylinder is shortened to return the feeding clamping elastic block to the original position, and then the extension rod of the feeding drive hydraulic cylinder is shortened to the high position to complete the reset.

[0078] As shown in Figures 8-11 The clamping part 300 includes a clamping support structure 310, a clamping drive structure 320 arranged on the clamping support structure 310, a clamping fixed structure 330 arranged on the clamping support structure 310 and matched with the clamping drive structure 320, and an initial feeding structure 340 arranged on the clamping fixed structure 330.

[0079] The clamping support structure 310 includes a clamping fixed base 311 arranged on the front surface of the vertical rail plate 212 and above the rectangular window, and a clamping support frame 312 arranged on the clamping fixed base 311.

[0080] The clamping drive structure 320 includes a clamping drive hydraulic cylinder 321 arranged on the front side of the clamping support frame 312 and with the extension rod transversely penetrating the clamping support frame 312, a clamping drive block 322 arranged on the extension rod of the clamping drive hydraulic cylinder 321, a clamping clamping block 323 arranged on the end surface of the clamping drive block 322, and a clamping clamping elastic block 324 arranged on the end surface of the clamping clamping block 323.

[0081] The clamping clamping elastic block and the feeding clamping elastic block are preferably made of materials with good elasticity and excellent wear resistance, such as rubber. Through the clamping clamping elastic block and the feeding clamping elastic block, the wire can be effectively clamped in the half funnel groove, and the wire can be effectively prevented from being extruded and deformed or broken due to the excellent deformation ability of the clamping clamping elastic block and the feeding clamping elastic block.

[0082] The clamping fixed structure 330 includes a clamping upper guide block 332 fixed on the front side of the clamping fixed base 311, a clamping lower guide block 331 fixed on the lower side of the clamping upper guide block 332, a clamping fixed clamping block 333 fixed on the front side of the clamping fixed base 311 and located between the clamping upper guide block 332 and the clamping lower guide block 331, a clamping upper funnel groove 335 vertically penetrating the clamping upper guide block 332, a clamping lower funnel groove 334 vertically penetrating the clamping lower guide block 331, and a clamping fixed half-funnel groove arranged on the front side of the clamping fixed clamping block 333.

[0083] The initial feeding structure 340 includes an initial feeding block 341 fixed above the clamping upper guide block 332, and an initial feeding funnel groove 342 vertically penetrating the initial feeding block 341.

[0084] The central axes of the clamping upper funnel groove 335, the clamping lower funnel groove 334, the clamping fixed half-funnel groove and the initial feeding funnel groove 342 coincide; the central axes of the clamping upper funnel groove 335, the feeding upper funnel groove 225 and the cutting feeding funnel groove 142 coincide; one end of the connecting frame 400 is fixed on the vertical rail plate 212 and the other end is fixed on the vertical fixed plate 111.

[0085] The working principle of the clamping part is as follows:

[0086] The wire is fed in through the initial feeding funnel groove and fed out through the clamping upper funnel groove and the clamping lower funnel groove. When clamping is needed, the extension rod of the clamping drive hydraulic cylinder is elongated to push the clamping drive block to move, the clamping clamping block moves with the clamping drive block and pushes the clamping clamping elastic block to press the wire in the clamping fixed half-funnel groove of the clamping fixed clamping block. When it needs to be loosened, the extension rod of the clamping drive hydraulic cylinder is shortened.

[0087] In addition, the feeding part needs to loosen the wire when feeding, and the clamping part needs to clamp the wire when the feeding part is reset. If the clamping part still clamps the wire when the feeding part is feeding, the wire will be deformed and worn, and even broken, which will affect the yield of the product, and even cause production accidents and affect normal production. Therefore, special attention should be paid.

[0088] It should be noted that each funnel groove described above is vertically arranged, the upper half of the funnel groove is inverted conical, and the lower half is cylindrical connected with the inverted conical, and the smallest diameter of the funnel groove is slightly larger than the wire, so that the wire can pass through easily when subjected to a smaller force. The shape of each half-funnel groove described above is the same as that of cutting the funnel groove vertically along the central axis, but the groove width of the half-funnel groove needs to be less than or equal to the diameter of the wire, so as to better fix the wire at the half-funnel groove.

[0089] The overall working process of the product is as follows:

[0090] (1) first pass through the clamping portion and the feeding portion;

[0091] (2) the feeding portion clamps the wire, while the clamping portion loosens the wire;

[0092] (3) the feeding portion descends to pull down the wire and make the lower end of the wire pass through the cutting portion;

[0093] (4) the cutting portion clamps the wire and resets after cutting;

[0094] (5) the clamping portion clamps the wire, while the feeding portion loosens the wire;

[0095] (6) the feeding portion ascends to reset.

[0096] It should be noted that all the features disclosed in the specification, or the steps in all the disclosed methods or processes, can be combined in any manner, except that mutually exclusive features and / or steps cannot be combined.

[0097] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions under the inspiration of the disclosure of the present application, and these solutions also belong to the disclosed range of the present application and fall within the protection scope of the present application.
