[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In one embodiment, see Figure 1-Figure 11 A wire cutting device comprises a cutting table 1, an end of which is provided with a material discharging table 5, the material discharging table 5 comprises a vertical pole arranged at the left end of the upper surface of the cutting table 1, the upper end of the vertical pole is fixedly connected with a horizontally arranged platform, the wire can be placed on the platform for extraction and cutting, and also comprises a power output mechanism 2, a clamping and shearing mechanism 3 and a clamping and pulling mechanism 4;

[0027] The clamping and pulling mechanism 4 comprises a left-right oriented guide column 7 arranged on the right side of the upper surface of the cutting table 1, the left and right ends of the guide column 7 are fixedly connected with a fixed block 6 fixedly connected with the cutting table 1, the middle part of the guide column 7 is slidably connected with the front and rear ends of the transverse shift seat 9 arranged in a front-back direction, a pulling support plate 10 extending to the left is arranged in the middle part of the upper surface of the transverse shift seat 9, and a protruding block 21 is arranged on the front and rear sides of the left side of the transverse shift seat 9, the protruding block 21 is slidably connected with a vertically arranged pulling slide bar 20, and the upper end of the pulling slide bar 20 is fixedly connected with a pulling pressure plate 11 arranged in a front-back direction and cooperating with the pulling support plate 10;

[0028] The clamping and shearing mechanism 3 is arranged on the left side of the clamping and pulling mechanism 4, and includes a column 26 fixedly connected to the cutting table 1. The two columns 26 are vertically arranged on the front and rear sides of the cutting table 1. The upper end of the column 26 is fixedly connected with a fixed support plate 27. A shearing fixed knife 28 is arranged on the right side of the fixed support plate 27. A vertically arranged clamping slide bar 32 is slidably connected to the front and rear ends of the fixed support plate 27. A clamping pressure plate 33 arranged in the front and rear directions is slidably connected above the clamping slide bar 32. The clamping pressure plate 33 and the fixed support plate 27 cooperate to complete the wire clamping. The upper end of the clamping slide bar 32 is fixedly connected with a shearing fixed plate 29 arranged in the front and rear directions. A shearing moving knife 30 cooperating with the shearing fixed knife 28 is arranged on the right side of the middle part of the shearing fixed plate 29. A clamping spring 34 is arranged between the shearing fixed plate 29 and the clamping pressure plate 33. The clamping spring 34 is sleeved on the outside of the clamping slide bar 32.

[0029] The power output mechanism 2 is arranged between the unloading table 5 and the clamping and shearing mechanism 3, and includes a vertical plate 18 fixedly connected to the cutting table 1. The vertical plate 18 is vertically arranged on the front and rear sides of the cutting table 1. The upper end of the vertical plate 18 is rotatably connected to the main shaft 17 arranged in the front and rear directions. The main shaft 17 moves the transverse seat 9 and the shear fixed plate 29 through the relevant transmission components. For example, when the transverse seat 9 drives the steel wire to move to the rightmost side, the shear fixed plate 29 will move downward, so that the shear moving knife 30 and the shear fixed knife 28 can achieve the cutting process of the steel wire. In addition, a driving motor 35 is arranged on the rear side of the vertical plate 18. The output shaft of the driving motor 35 is fixedly connected to the first transmission pulley 36. The first transmission pulley 36 is connected to the second transmission pulley 38 through the conveyor belt 37. The second transmission pulley 38 is fixedly connected to the front side of the main shaft 17. The driving motor 35 drives the main shaft 17 to rotate clockwise through the belt drive.

[0030] In one case of the present embodiment, a slide groove 39 arranged in a left-right direction is provided on the right side of the lower surface of the fixed support plate 27, and the slide groove 39 is slidably connected to the left side of the shear fixed knife 28. A tensioning spring 40 is provided between the left end of the slide groove 39 and the shear fixed knife 28. When the transverse displacement seat 9 moves to the left side, the left end of the pulling support plate 10 will press against the shear fixed knife 28. At this time, the shear fixed knife 28 will retreat to the left side. At this time, the exposed steel wire will move to the upper surface of the pulling support plate 10, thereby completing the subsequent clamping process of the free end of the steel wire.

[0031] In one case of the present embodiment, a clamping plate 31 arranged in a front-to-rear direction is fixedly connected to the lower end of the clamping slide bar 32, and the front and rear sides of the clamping plate 31 are slidably connected to the bottom of the column 26. A rack 42 is vertically arranged in the middle of the left side of the clamping plate 31, and a toothless gear 41 is fixedly connected to the middle of the main shaft 17. When the tooth part of the toothless gear 41 rotates clockwise until it contacts the rack 42, the rack 42 moves downward, thereby causing the shearing plate 29 to move downward, thereby achieving the clamping and cutting of the wire, and a rotating beam 16 is arranged at the rear end of the main shaft 17, and the pulling rod 1 is connected to the rotating beam 16 5, and the other side of the pulling rod 15 is connected to the transverse seat 9. When the rotating beam 16 rotates with the main shaft 17, the rotating beam 16 pulls the transverse seat 9 to move left and right along the guide column 7 through the pulling rod 15, so that the main shaft 17 can simultaneously drive the movement of the shear fixing plate 29 and the transverse seat 9, and the direction of the toothed portion of the toothless gear 41 is the same as that of the rotating beam 16, that is, after the rotating beam 16 pushes the transverse seat 9 to move to the far right through the pulling rod 15, the toothed portion of the toothless gear 41 contacts with the rack 42, so that after the steel wire is pulled out, the shear fixing plate 29 will move downward to complete the fixing and shearing process.

[0032] In one case of the present embodiment, a limit ring 8 is provided on the right side of the guide column 7, a locking bolt is provided on the outside of the limit ring 8, and the limit ring 8 is provided on the right side of the transverse displacement seat 9. After the transverse displacement seat 9 moves to the right side and contacts with the limit ring 8, the transverse displacement seat 9 will stop moving, thereby limiting the maximum moving distance of the transverse displacement seat 9 to the right by the limit ring 8, that is, achieving the effect of limiting the maximum distance of the wire withdrawal, and the rear end of the transverse displacement seat 9 is rotatably connected to the rotating plate 12, the middle part of the rotating plate 12 is slidably connected to the right side of the pulling rod 15, the right end of the pulling rod 15 is fixedly connected to the limit plate 14, and the limit plate 14 is connected to the rotating plate 12. A return spring 13 is provided between the rotating plates 12, and the return spring 13 is sleeved on the outside of the pulling rod 15. Therefore, when the transverse displacement seat 9 moves to the right and contacts the limit ring 8, the transverse displacement seat 9 stops moving at this time. At this time, the pulling rod 15 will continue to extend to the right, but the steel wire stops being pulled to the right, which means that the effect of limiting the cutting length of the steel wire is achieved. In order to better adjust the moving distance of the transverse displacement seat 9, a length adjustment component 50 can be provided at the end of the main shaft 17. The length adjustment component 50 can adjust the reciprocating movement range of the left end of the pulling rod 15, and cooperate with the adjustment of the moving distance of the transverse displacement seat 9 to achieve the effect of fixed-length cutting of the steel wire. The length adjustment component 50 includes a fixed seat 47 fixedly connected to the main shaft 17, according to the attached Figure 2The position is described as follows: the fixed seat 47 is fixedly connected to the left position of the middle part of the rotating beam 16; the right side of the rotating beam 16 is slidably connected to the sliding sleeve 43; the sliding sleeve 43 is rotatably connected to the left end of the pulling rod 15; the left side of the rotating beam 16 is slidably connected to the counterweight 55; the weight of the sliding sleeve 43 is balanced by the counterweight 55, so that the rotating beam 16 can rotate more stably; and baffles 49 are provided at both ends of the rotating beam 16; tension springs 48 are provided between the baffle 49 and the sliding sleeve 43 and between the baffle 49 and the counterweight 55; the tension spring 48 pulls the counterweight 55 and the sliding sleeve 43 toward the end of the rotating beam 16; bearing seats 46 are provided on the front and rear sides of the fixed seat 47; a transmission rod is rotatably connected to the bearing seat 46; the transmission rod The front and rear sides are fixedly connected with winding pulleys 45, and a traction rope 44 is wound around the outside of the winding pulley 45. The free ends of the two traction ropes 44 are respectively connected to the sliding sleeve 43 and the counterweight 55. The two winding pulleys 45 rotate synchronously, and the two winding pulleys 45 synchronously retract or release the traction rope 44, so that the counterweight 55 and the sliding sleeve 43 will move toward the center of the rotating beam 16 at the same time or move away from the center of the rotating beam 16 at the same time. In order to reduce the weight of the entire rotating beam 16, the moving distance of the counterweight 55 is small. Therefore, the diameter of the winding pulley 45 matched with the counterweight 55 is smaller, so that the moving speed of the counterweight 55 is smaller than the moving speed of the sliding sleeve 43.

[0033] In one case of the present embodiment, a limiting cross bar 19 arranged in a front-to-rear direction is fixedly connected to the lower end of the pulling slide bar 20, and a pulling spring 22 is arranged between the pulling pressure plate 11 and the protruding block 21. The pulling spring 22 is sleeved on the outside of the pulling slide bar 20, and the pulling spring 22 will continuously pull the pulling slide bar 20 downward, so that the pulling pressure plate 11 and the pulling support plate 10 can fix and clamp the right end of the steel wire, and a lifting assembly 25 is arranged on the left side of the upper surface of the cutting table 1. When the limiting cross bar 19 moves to the left side and cooperates with the lifting assembly 25, the pulling pressure plate 11 will be lifted upward, so that the pulling pressure plate 11 and the pulling support plate 10 are separated to complete the end clamping of the steel wire. The lifting assembly 25 includes a limit seat 52 fixedly connected to the cutting table 1, and the upper end of the limit seat 52 is slidably connected to a limit slide bar 53 set in the left and right directions. The left end of the limit slide bar 53 is fixedly connected to the limit plate 51, and the right end of the limit slide bar 53 is fixedly connected to the left end of the trapezoidal guide block 23. The cross section of the trapezoidal guide block 23 is a right-angled trapezoid, the upper surface of the trapezoidal guide block 23 is a short side, and the right end of the trapezoidal guide block 23 is an inclined surface. Therefore, when the limit cross bar 19 moves from right to left and contacts the trapezoidal guide block 23, it will be pushed upward, and a protrusion 24 is provided on the upper surface of the trapezoidal guide block 23. When the limit cross bar 19 contacts the protrusion 24, the protrusion 24 The protrusion 24 will block the relative displacement of the limit cross bar 19 and the trapezoidal guide block 23. At this time, the trapezoidal guide block 23 will move to the left synchronously with the limit cross bar 19, and a limit spring 54 is arranged between the trapezoidal guide block 23 and the limit seat 52. The limit spring 54 is sleeved on the outside of the limit slide bar 53. When the limit spring 54 is compressed and cannot be compressed further, the limit cross bar 19 will move upward from right to left over the protrusion 24, and because the limit slide bar 53 is lower than the height of the limit cross bar 19, the limit cross bar 19 will then drop rapidly under the action of the pulling spring 22, and the pulling pressure plate 11 and the pulling support plate 10 will fix the free end of the steel wire at this time.

[0034] During the implementation of this embodiment, the steel wire is placed on the upper surface of the discharge table 5, and the main shaft 17 is first rotated clockwise by driving the motor 35. At this time, the sliding sleeve 43 on the rotating beam 16 rotates to the right position, but the shearing movable knife 30 has not started to move downward, that is, the gear part of the toothless gear 41 is about to contact the rack 42. At this time, the steel wire can be pulled out to the right, and the free end of the steel wire passes through the clamping plate 33 and the fixed support plate 27, so that the steel wire extends slightly to the right to the right side of the shearing fixed knife 28. The left and right positions of the limit ring 8 are adjusted, and the winding pulley 45 is rotated to adjust the position of the sliding sleeve 43 so that the left and right movement distance of the transverse displacement seat 9 meets the length requirement of the fixed-length cutting steel wire. At this time, the entire cutting device is ready.

[0035] After the preliminary cutting positioning process, the drive motor 35 is started, and the main shaft 17 continues to rotate clockwise. The tooth part of the toothless gear 41 will rotate clockwise and contact the rack 42. At this time, the rack 42 will move downward, and the clamping slide bar 32 drives the clamping pressure plate 33 and the shearing fixed plate 29 to move downward at the same time. When the clamping pressure plate 33 is pressed downward on the upper surface of the fixed support plate 27 to complete the fixing of the steel wire, the clamping spring 34 is compressed at this time, and the shearing fixed plate 29 drives the shearing moving knife 30 to continue to move downward. After the shearing moving knife 30 moves to the bottom and cooperates with the shearing fixed knife 28, the shearing moving knife 30 and the shearing fixed knife 28 cut off the part of the steel wire extending to the outside.

[0036] During the wire pulling process, the main shaft 17 continues to rotate. At this time, the toothed part of the toothless gear 41 is disengaged from the rack 42, and the clamping spring 34 pushes the shear fixed plate 29 upward. The shear moving knife 30 is disengaged from the shear fixed knife 28 above the moving knife, and at this time, the clamping pressure plate 33 only falls on the fixed support plate 27 under gravity. At this time, the wire can be pulled out to the right, but the wire itself has a certain friction force. Therefore, when the pulling support plate 10 moves to the left, the wire can extend to the upper surface of the pulling support plate 10, and the rotating beam 16 pulls the transverse seat 9 to move to the left through the pulling rod 15. In the process of the transverse seat 9 moving from right to left, the limit cross bar 19 will first contact the trapezoidal The inclined surface of the guide block 23 contacts, and the limit cross bar 19 moves upward. The pulling plate 10 and the pulling pressure plate 11 separate from each other. As the traverse seat 9 continues to move to the right, the left end of the pulling plate 10 will press against the left end of the shearing fixed knife 28. At this time, the tensioning spring 40 is compressed, and the shearing fixed knife 28 is pushed to the left and retracted. At this time, the steel wire originally falling on the shearing fixed knife 28 will extend to the top of the pulling plate 10, and as the traverse seat 9 continues to move to the left, the limit spring 54 is compressed to the limit and cannot move further. The limit cross bar 19 passes over the protrusion 24 and moves to the left side of the trapezoidal guide block 23. The trapezoidal guide block 23 is in the limit spring 54. The left side of the trapezoidal guide block 23 is designed as an arc surface, which is convenient for the limit line 19 to move upward and from left to right. After passing the trapezoidal guide block 23, when the limit cross bar 19 moves to the inclined part of the trapezoidal guide block 23, the limit cross bar 19 will push the trapezoidal guide block 23 to move to the left, that is, the limit cross bar 19 will move downward quickly, that is to say, in the process of the transverse displacement seat 9 moving to the right, the limit cross bar 19 will be quickly lifted for a distance, at this time, the pulling pressure plate 11 and the pulling support plate 10 will release the steel wire for a period of time, but because the distance between the pulling pressure plate 11 and the pulling pressure plate 11 clamped the steel wire is long enough in the initial stage, after the limit cross bar 19 drops again, the pulling pressure plate 11 and the pulling support plate 10 will clamp the steel wire again, and the steel wire will be pulled out to the right at this time.

[0037] Fixed-length cutting processing, as the main shaft 17 continues to rotate clockwise, the transverse seat 9 moves to the right side and contacts the limit ring 8, the transverse seat 9 stops moving, and the steel wire stops being pulled out. At this time, when the main shaft 17 continues to rotate, the steps of the preliminary cutting positioning processing will be repeated, and the shearing moving knife 30 and the clamping pressure plate 33 will move downward to complete the cutting processing of the steel wire. At this time, the steel wire is cut into a fixed length and falls on the cutting table 1, realizing the automated cutting processing.

[0038] The present invention is applicable to a wire cutting device. By setting a power output mechanism 2 to simultaneously drive the movement of a clamping and shearing mechanism 3 and a clamping and pulling mechanism 4, the wire can be continuously cut into a set length, thereby improving the processing efficiency. In addition, the entire device only requires one power output mechanism 2, thereby reducing the manufacturing cost and use cost of the entire device, and is suitable for popularization and use.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
