[0002] Iron wire is a kind of metal wire drawn from iron. The composition of iron wire varies according to its use. It contains: iron, cobalt, nickel, copper, carbon, zinc, and other elements. In order to facilitate the sale and transportation of iron wire, the produced iron wire is generally rolled into a coil. The length of iron wire required in different environments is different. At this time, a straightening and cutting machine is needed to straighten the iron wire rolled into a coil and cut the straightened iron wire at a fixed distance.
[0003] When the existing straightening and cutting machine is cutting and processing a long iron wire, since the part of the iron wire that needs to be cut is extended out of the straightening and cutting machine and is suspended in the air, there is only one supporting point for the part of the iron wire that needs to be cut, and the distance between the part of the iron wire that needs to be cut and the supporting point gradually increases after it is extended out of the straightening and cutting machine. As a result, the iron wire is prone to sag and bend under the action of its own gravity, and the iron wire is prone to contact with the ground after it sags and bends. After the iron wire sags and bends and contacts the ground, continuing to be output from the straightening and cutting machine will cause the iron wire to bend again, thereby requiring the cut iron wire to be straightened a second time, which is inconvenient and increases the workload.

[0032] Embodiment: A wire cutting device, see Figure 1-Figure 3The invention comprises a straightening and cutting machine body 1, which is composed of a support, a guide rail, a slider, a rotating shaft, a straightening wheel, a tensioning spring, a gear, a synchronous belt transmission component, a servo motor, a belt transmission component, a protective cover, an n-shaped fixing plate, a cylinder, a cutter and a wire block. The left and right sides of the top of the support are symmetrically connected with guide rails, and sliders are slidably connected in the four guide rails. The rotating shafts are rotatably connected between the two sliders corresponding to the front and the back and between the lower parts of the two guide rails corresponding to the front and the back. The four rotating shafts are connected with straightening wheels, and the outer walls of the straightening wheels are spaced apart along the axial direction by a plurality of There are a plurality of wire grooves, a tensioning spring is connected between the top of the slider and the top of the guide rail, the front sides of the four rotating shafts are connected with gears, the two adjacent gears are meshed, and a synchronous belt transmission assembly is connected between the two rotating shafts corresponding to the left and right sides of the lower side. The synchronous belt transmission assembly consists of two synchronous wheels and a synchronous belt. The two synchronous wheels are respectively connected to the front sides of the two rotating shafts corresponding to the left and right sides of the lower side, and the synchronous belt is sleeved between the two synchronous wheels. A servo motor is installed on the lower right part of the support platform, and a belt transmission assembly is connected between the output shaft of the servo motor and the rotating shaft on the lower right side. The belt transmission assembly consists of two belts The machine body 1 is composed of a pulley and a belt, one of which is connected to the output shaft of the servo motor, the other is connected to the rear side of the rotating shaft on the lower right side, the belt is sleeved between the two pulleys, a protective cover is connected between the four guide rails, an n-shaped fixed plate is connected to the right side of the top of the support, a wire block is connected to the n-shaped fixed plate, a cylinder is installed on the top of the n-shaped fixed plate, a cutter is connected to the telescopic rod of the cylinder, a fixed frame 2 is connected to the right rear side of the support on the straightening and cutting machine body 1, and the fixed frame 2 is composed of a fixed block, a cross plate, a mounting rod and an arc guide sleeve, and the fixed block is connected to the straightening and cutting On the right rear side of the support platform of the machine body 1, the cross plate is connected to the right side of the fixed block, the two mounting rods are symmetrically connected to the top of the cross plate, the two arc guide sleeves are respectively connected to the front upper parts of the two mounting rods, the two arc guide sleeves on the fixed frame 2 are slidably connected with the arc rod 3, and a trustee 5 is connected between the two arc rods 3. The trustee 5 is located in the arc rod 3, and the trustee 5 is aligned with the wire block of the straightening and cutting machine body 1. A discharge port is opened axially on the front side of the trustee 5, and a spring A4 is sleeved on the arc rod 3, and the spring A4 is connected to the arc rod 3 and the arc guide sleeve on the fixed frame 2.
[0033] When it is necessary to straighten the coiled wire and cut the straightened wire at a fixed distance, pull out the wire end and pass the wire end through the upper and lower straightening wheels to align with the conductor block. The tensioning spring can make the upper straightening wheel press the wires of different sizes onto the lower straightening wheel, so that the wires of different sizes can be straightened and cut. The servo motor drives the lower right shaft to rotate through the belt transmission assembly. The rotation of the lower right shaft drives the lower left shaft to rotate through the synchronous belt transmission assembly. The rotation of the lower shaft drives the upper shaft to rotate in the opposite direction through the gear, so that the upper and lower straightening wheels can rotate in opposite directions. The straightening wheels on both sides rotate in opposite directions through the wire grooves thereon to straighten the wire and push the straightened wire to the right. The straightened wire then extends out of the conductor block and enters the trustee 5. The trustee 5 can lift the extended suspended wire to prevent the straightened wire from sagging and bending. The cylinder works to make the cutter move back and forth downward and upward. The cutter can cut the straightened wire downward. The trustee 5 is rotated so that the discharge port on it faces downward to pour out the cut wire. The rotation of the trustee 5 drives the arc rod 3 to rotate to compress the spring A4. The trustee 5 is released, and under the resetting action of the spring A4, the arc rod 3 can drive the trustee 5 to rotate in the opposite direction and reset.
[0034] See also Figure 4-Figure 5 In the present invention, a pushing assembly and a pulling assembly are also included. The pushing assembly is composed of a connecting rod 61, a push rod 62, an L-shaped block 63 and a slide plate 64. The connecting rod 61 is connected to the rear side of the cutter of the straightening and cutting machine body 1, and the rear end of the connecting rod 61 passes through the rear side of the n-shaped fixing plate on the straightening and cutting machine body 1. The rear end of the connecting rod 61 is connected to the push rod 62. The slide plate 64 is slidably connected between the two mounting rods on the fixing frame 2. The left side of the slide plate 64 is connected to the L-shaped block 63. The L-shaped block 63 is provided with a vertical groove and an oblique groove. The vertical groove is located on the upper side of the oblique groove, and the vertical groove and the oblique groove are connected. The push rod 62 is located at the L-shaped block 63. In the vertical groove on the upper part, the pulling assembly consists of an arc-shaped connecting block 65, a pull rope 66 and a wire plate 67. The two arc-shaped connecting blocks 65 are respectively connected to the lower part of the two arc-shaped rods 3, and the lower parts of the two mounting rods on the fixed frame 2 are connected with the wire plate 67. The bottoms of the two arc-shaped connecting blocks 65 are provided with arc-shaped slide grooves that cooperate with the wire plate 67 so that the arc-shaped connecting blocks 65 can slide on the wire plate 67. The two arc-shaped connecting blocks 65 are connected with pull ropes 66, and the pull ropes 66 are located in the arc-shaped slide grooves. The two pull ropes 66 respectively pass through the two wire plates 67 and the two mounting rods on the fixed frame 2, and are connected to the front side of the slide plate 64.
[0035] The cutter moves downward and drives the push rod 62 downward through the connecting rod 61. When the push rod 62 moves downward in the vertical groove on the L-shaped block 63, it will not push the L-shaped block 63 to move. When the cutter moves downward to cut the wire, the push rod 62 moves downward into the inclined groove on the L-shaped block 63, so that the cutter continues to move downward and the push rod 62 continues to move downward. After entering the inclined groove, the push rod 62 continues to move downward to squeeze the L-shaped block 63 to move right. The L-shaped block 63 moves right and drives the slide plate 64 to move right. The slide plate 64 moves right and pulls the arc-shaped connecting block 65 through the pull rope 66 to drive the arc rod 3 to rotate, so that the trustee 5 rotates to pour out the cut wire inside it, and the spring A4 is Compression; the cutter moves upward and drives the push rod 62 upward through the connecting rod 61. When the push rod 62 is located in the inclined groove on the L-shaped block 63 and moves upward, the L-shaped block 63 is squeezed to move left and reset. The L-shaped block 63 moves left and drives the slide plate 64 to move left to release the pull rope 66. Under the reset action of the spring A4, the arc rod 3 can drive the hosting 5 and the arc-shaped connecting block 65 to rotate in the opposite direction and reset. When the push rod 62 moves up to the vertical groove on the L-shaped block 63, the push rod 62 continues to move upward in the vertical groove on the L-shaped block 63 without pushing the L-shaped block 63 to move. In this way, the cut wire can be automatically poured out, thereby improving work efficiency.
[0036] See also Figure 6-Figure 7 In the present invention, it also includes a guide rod 71 and a movable plate 72. Two guide rods 71 are symmetrically connected to the bottom of the hosting tube 5. A movable plate 72 is slidably connected between the two guide rods 71. A spring B73 is connected between the movable plate 72 and the guide rod 71. N-shaped support blocks 74 are evenly spaced from left to right on the movable plate 72. The n-shaped support blocks 74 extend into the hosting tube 5. The upper part of the n-shaped support block 74 is rotatably connected to a guide wheel 75. A guide block 76 is connected to the left side of the bottom of the hosting tube 5, and the left side of the top of the guide block 76 is an inclined surface.
[0037] The iron wire can be guided by the guide block 76 to move to the right to the upper side of the guide wheel 75 to prevent the iron wire from moving into the n-shaped support block 74 and affecting subsequent pouring. The cooperation of the n-shaped support block 74 and the guide wheel 75 can lift the iron wire in the tube 5 to prevent the end of the iron wire from bending due to friction with the bottom of the tube 5. The guide wheel 75 can make the iron wire move more smoothly to the right in the tube 5.
[0038] See also Figure 8 In the present invention, it also includes two U-shaped rods 83 symmetrically connected to the bottom of the movable plate 72, and the rear sides of the two U-shaped rods 83 are connected to push blocks 84. The upper parts of the two mounting rods on the fixed frame 2 are connected to the fixed rods 81, and the lower parts of the two fixed rods 81 are connected to arc blocks 82. The outer walls of the arc blocks 82 gradually thicken from bottom to top, and the outer walls of the two arc blocks 82 are in contact with the two push blocks 84 respectively.
[0039] When the trustee 5 rotates to pour out the cut wire inside, the movable plate 72 is driven to rotate through the guide rod 71, and the movable plate 72 rotates through the U-shaped rod 83 to drive the push block 84 to rotate along the arc block 82. Since the outer wall of the arc block 82 gradually thickens from bottom to top, the push block 84 is squeezed by the arc block 82 to move away from the trustee 5 when it rotates, so that the U-shaped rod 83 drives the movable plate 72 to move away from the trustee 5, so that the n-shaped support block 74 and the guide wheel 75 are moved out of the trustee 5, so as to prevent the cut wire inside the trustee 5 from being caught by the n-shaped support block 74 or the guide wheel The wheel 75 blocks the pouring out, thereby ensuring that the cut wire in the trustee 5 can be poured out smoothly; when the movable plate 72 moves in the direction away from the trustee 5, the spring B73 is compressed. When the trustee 5 rotates in the opposite direction to reset, the movable plate 72 is driven to rotate in the opposite direction through the guide rod 71, so that the U-shaped rod 83 drives the push block 84 to rotate in the opposite direction along the arc block 82 to reset. Under the reset action of the spring B73, the movable plate 72 moves in the direction close to the trustee 5 to reset, so that the n-shaped support block 74 and the guide wheel 75 are moved back into the trustee 5 to support the next wire.
[0040] See also Fig. 9 In the present invention, it also includes a screw rod 91 and a limit block 92. Two screw rods 91 are symmetrically rotatably connected to the conductor block of the straightening and cutting machine body 1. The limit block 92 is threadedly connected to the two screw rods 91, and the limit block 92 is located in the conductor block on the straightening and cutting machine body 1. The limit block 92 is slidably connected to the conductor block of the straightening and cutting machine body 1. An arc-shaped accommodating groove is opened at the bottom of the limit block 92, and the lower parts of the two screw rods 91 are connected to rubber handles 93.
[0041] The height of the limit block 92 can be adjusted according to actual needs. When the height of the limit block 92 needs to be adjusted, the rubber handle 93 is rotated or reversed to rotate the screw 91, so that the limit block 92 moves upward or downward to limit the iron wires of different sizes, so as to avoid the iron wire in the conductor block from bending upward when the iron wire is cut, so as to facilitate the subsequent smooth delivery of the iron wire from the conductor block. The rubber handle 93 can increase the friction with the hand, so that the screw 91 can be rotated to quickly adjust the height of the limit block 92.
[0042] See also Fig.10 In the present invention, it also includes a mounting plate 101, a guide roller A102 and a guide roller B103. The left sides of the two left guide rails on the straightening and cutting machine body 1 are connected with mounting plates 101, and the two mounting plates 101 are rotatably connected with guide rollers A102. Two guide rollers B103 are rotatably connected between the two mounting plates 101, and the guide roller B103 is located on the left side of the guide roller A102, and the guide roller B103 is perpendicular to the guide roller A102.
[0043] The guide rollers A102 and B103 can guide the iron wire to prevent the iron wire rolled into a coil from being pulled out and stuck outside the straightening and cutting machine body 1, thereby ensuring that the iron wire can smoothly enter the straightening and cutting machine body 1 for straightening and cutting.
