The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] Please refer to Figure 1 to Figure 5 The embodiment of the utility model provides a cutting device for iron wire production, comprising:

[0042] A placing table 1, a first slide groove 11 is provided on one side of the top of the placing table 1;

[0043] The guide assembly 2 is arranged on the other side of the top of the placing table 1, and is used for allowing the iron wire to pass through and guiding and limiting the iron wire;

[0044] The cutting assembly 3 is arranged on the top of the placing table 1 between the guiding assembly 2 and the first slide groove 11, and comprises a cylinder 31 and a cutter 32, wherein the output end of the cylinder 31 is connected to the top of the cutter 32;

[0045] The stretching assembly 4 is disposed in the first slide groove 11 and is slidably connected to the inner wall of the first slide groove 11, and is used to clamp the movable end of the fixed iron wire and drive the iron wire to stretch along the length direction of the first slide groove 11 toward the side close to the limiting plate 51;

[0046] The fixed-length component 5 is arranged in the first slide groove 11 on the side of the stretching component 4 away from the cutting component 3, and includes a limit plate 51 and a driving member 52. The limit plate 51 is slidably connected to the inner wall of the first slide groove 11, and the driving member 52 can drive the limit plate 51 to slide along the length direction of the first slide groove 11. The top of the placement table 1 is also provided with a scale 53 arranged in parallel with the first slide groove 11, and the zero scale of the scale 53 is aligned with the cutting end of the cutter 32.

[0047] The guide assembly 2, the cutting assembly 3, the stretching assembly 4 and the fixed-length assembly 5 are arranged in sequence along the direction in which the iron wire is stretched. The iron wire passes through the guide assembly 2, and the iron wire is limited by the guide assembly 2 to prevent the iron wire from shaking and deviating when being stretched, so that the iron wire is stretched in a straight line direction. The movable end of the iron wire is fixed by the stretching assembly 4 after passing through the guide assembly 2, and the iron wire is conveniently driven to be stretched by the stretching assembly 4; according to the scale 53 on the top of the placement table 1, it is convenient to move the limit plate 51 to the set position and fix it according to the cutting requirements. After fixing the limit plate 51, the subsequent wire cutting is based on the position of the limit plate 51. It is not necessary to measure the length of the iron wire to be cut before each cutting, nor is it necessary to observe the reading of the scale 53 each time cutting, so that the cutting of the iron wire is more intuitive and convenient; when cutting, the stretching assembly 4 is driven to slide along the length direction of the first slide 11 until the movable end of the iron wire contacts the limit plate 51. At this time, the cutter 32 is driven to descend by the cylinder 31 to complete the fixed-length cutting of the iron wire.

[0048] In a preferred embodiment, if Figure 3 and Figure 4As shown, the guide assembly 2 includes a guide plate 21 arranged on the top of the placing table 1, a pressing plate 22 is hinged on the top of the guide plate 21, a lower guide groove 211 is provided on the top of the guide plate 21, an upper guide groove 221 corresponding to the lower guide groove 211 is provided on the bottom of the pressing plate 22, a second slide groove connected to the upper guide groove 211 is provided in the pressing plate 22, and a fixing member 23 for fixing the iron wire is slidably connected in the second slide groove.

Before cutting, the iron wire is placed in the lower guide groove 211 on the guide plate 21, and the end of the iron wire extends to the outside of the guide plate 21, and then the pressing plate 22 is rotated so that the pressing plate 22 is pressed on the top of the guide plate 21. At this time, the upper guide groove 221 and the lower guide groove 211 are combined into a guide channel, and the diameter of the guide channel is slightly larger than the diameter of the iron wire. The iron wire can slide in the guide channel. After the iron wire passes through the guide channel, it is convenient to straighten the iron wire bent due to winding.

[0049] In a preferred embodiment, if Figure 3 and Figure 4 As shown, the fixing member 23 includes a connecting rod 231, a fixing plate 232, a first spring 233 and a handle 234. The handle 234 is in a "mountain" shape, including a main connection part and two side connection parts. One end of the connecting rod 231 is connected to the fixing plate 232, and the other end penetrates the pressing plate 22 and is rotatably connected to the main connection part of the handle 234. The outer surface of the connecting rod 231 is sleeved with a first spring 233. One end of the first spring 233 is fixedly connected to the fixing plate 232, and the other end is fixedly connected to the inner wall of the second slide groove. The fixing plate 232 is slidably connected to the inner wall of the second slide groove. The top of the pressing plate 22 is provided with two grooves for inserting the side connection parts of the handle 234. The top of the pressing plate 22 is also provided with a fixing sleeve, and the first screw 222 is sleeved on the inner thread of the fixing sleeve. A fixing groove for inserting the first screw 222 is provided on one of the side connection parts of the handle 234.

[0050] Before the pressing plate 22 is pressed onto the guide plate 21, the handle 234 is pulled so that the ends of the two side connecting parts of the handle 234 are against the top of the pressing plate 22. At this time, the first spring 233 is in a compressed state, the fixing plate 232 is retracted into the second slide groove, and the wire can be stretched. When the movable end of the wire is stretched to contact with the limit plate 51, the handle 234 is rotated, and the two side connecting parts of the handle 234 are inserted into the groove at the top of the pressing plate 22. Under the elastic action of the first spring 233, the wire in the upper guide groove 211 is squeezed and fixed to prevent the cut end of the wire from rebounding due to its own toughness and causing harm to the operator; the first screw 222 is rotated so that the end of the first screw 222 is inserted into the groove of the side connecting part of the handle 234, and the handle 234 is further fixed to apply stable pressure to the wire to prevent the first spring 233 from pushing up when the wire is stretched.

[0051] In a preferred embodiment, if Figure 2 As shown, the stretching assembly 4 includes a second screw rod 41, a fixed platform 42, a mounting plate 43, a bidirectional screw rod 44 and a clamping plate 45. The second screw rod 41 is arranged in the first slide groove 11, the bottom of the fixed platform 42 is threadedly sleeved with the outer surface of the second screw rod 41, one end of the second screw rod 41 passes through the side wall of the placement platform 1 and is provided with a first rotating handle, the mounting plate 43 is symmetrically arranged on the top of the fixed platform 42, the bidirectional screw rod 44 is rotatably connected between the mounting plates 43, and the clamping plate 45 is threadedly sleeved on the bidirectional screw rod 44. A positioning plate 46 is arranged on one side of the top of the fixed platform 42 close to the limit plate 51, and the clamping plate 45 is symmetrically arranged about the center of the positioning plate 46.

[0052] The movable end of the wire is brought into contact with the positioning plate 46, and then the two-way screw rod 44 is rotated to drive the two clamping plates 45 to approach each other, so as to stably clamp the movable end of the wire. The opposite surfaces of the two clamping plates 45 are provided with anti-skid rubber pads, which protect the wire and increase the friction between the wire and the clamping of the wire, thereby improving the stability of the clamping of the wire and preventing the wire from slipping off between the clamping plates 45 when the wire is stretched. The movable end of the wire is brought into contact with the positioning plate 46 to avoid excessive driving of the stretching assembly 4 to move, which may cause the end of the wire to be bent when it contacts the limiting plate 51, thereby avoiding errors in the cutting length. The cutting length of the wire is the length between the cutter 32 and the positioning plate 46. When the limiting plate 51 is driven, the scale position of the limiting plate 51 is the cutting length of the wire plus the thickness of the positioning plate 46.

[0053] In a preferred embodiment, if Figure 2 As shown, the driving member 52 includes a third screw 521, which is disposed in the first slide groove 11, the limiting plate 51 is threadedly sleeved with the outer surface of the third screw 521, one end of the third screw 521 passes through the side wall of the placing table 1 and is provided with a second rotating handle, and the third screw 521 passes through the fixing table 42. The position of the limiting plate 51 is adjusted by the third screw 521.

[0054] In a preferred embodiment, if Figure 5 As shown, a cutting platform 33 is provided below the cutter 32 , and the cylinder 31 is provided on the cutting platform 33 through a mounting frame 34 . A cutting groove 331 is provided on the top surface of the cutting platform 33 facing the cutter 32 .

[0055] The mounting frame 34 is arranged on the cutting table 33, and the cylinder 31 is arranged on the top of the mounting frame 34. The output end of the cylinder 31 is fixedly connected to the top of the cutter 32. Two sets of limit rods are also arranged on the mounting frame 34. The two sides of the top of the cutter 32 are slidably sleeved on the limit rods to guide the cutter 32 to move up and down stably; the cutting table 33 is flush with the bottom of the lower guide groove 211 in the guide assembly 2. When the iron wire is stretched, the iron wire is placed on the top of the cutting table 33. When the cutter 32 cuts the iron wire, the cutting end at its bottom is inserted into the cutting groove 331 to complete the cutting of the iron wire.

[0056] In a preferred embodiment, if Figure 5 As shown, a cutting notch 321 is provided at the bottom of the cutter 32. When cutting, the cutting notch 321 is directly opposite to the curvature of the upper surface of the wire, so that the cut end of the wire is more even.

[0057] Working principle: When cutting, the limiting plate 51 is moved to the set position according to the cutting length requirement of the iron wire, and then one end of the iron wire is pulled to put the iron wire into the lower guide groove 211 in the guide plate 21, and then the pressing plate 22 is pressed on the guide plate 21, and the iron wire can be pulled between the upper guide groove 221 and the lower guide groove 211. The upper guide groove 221 and the lower guide groove 211 are used to limit the position of the iron wire to prevent the iron wire from shaking and deviating when being stretched, so that the iron wire is stretched in a straight line direction, and the movable end of the iron wire is aligned with the positioning plate 46 abuts, the iron wire is clamped and fixed by the clamping plate 45, and the second screw 41 is rotated to drive the fixing platform 42 to move towards the direction close to the limiting plate 51 until the positioning plate 46 abuts the limiting plate 51. At this time, the cutter 32 is driven down by the cylinder 31 to complete the fixed-length cutting of the iron wire. Through the setting of the positioning plate 46 and the limiting plate 51, there is no need to measure the length of the iron wire to be cut before each cutting, and there is no need to observe the reading of the scale 53 every time cutting, which makes the cutting of the iron wire more intuitive and convenient. When the positioning plate 46 abuts against the limiting plate 51, the handle 234 is rotated, and the two side connection parts of the handle 234 are inserted into the groove at the top of the pressure plate 22. Under the elastic action of the first spring 233, the iron wire in the upper guide groove 211 is squeezed and fixed, so as to prevent the cut end of the iron wire from rebounding due to its own toughness and causing harm to the operator; the first screw 222 is rotated to make the end of the first screw 222 inserted into the groove of the side connection part of the handle 234, so as to further fix the handle 234 and apply stable pressure to the iron wire, so as to prevent the first spring 233 from pushing up when the iron wire is stretched.
