[0028] Combine the following Figure 1-Figure 5The wire material fixed-length cutting device of the embodiment of the utility model is described.

[0029] The first embodiment of the utility model provides a wire cutting device, such as Figures 1 to 3 As shown, the wire rod fixed-length cutting device includes a frame 1 and a cutting mechanism 2 and a first clamping mechanism arranged on the frame 1.

[0030] Among them, the cutting mechanism 2 includes a cutting board 21 and a lap joint 22, the cutting board 21 is arranged on the frame 1, the first end of the lap joint 22 is rotatably arranged on the frame 1, the second end of the lap joint 22 is overlapped on the cutting board 21, and the second end of the lap joint 22 is used to press the wire 7 against the cutting board 21; the first clamping mechanism includes a first driving component 31 and a first clamping component 32, the first driving component 31 is arranged on the frame 1, the first clamping component 32 is arranged on the first driving component 31, and the first driving component 31 is used to drive the first clamping component 32 to move between a first position and a second position along a first direction. In the first position, the first clamping component 32 is located on the first side of the lap joint 22, and in the second position, the first clamping component 32 is located on the second side of the lap joint 22.

[0031] It can be understood that the first clamping assembly 32 is used to clamp the wire 7, and the first driving assembly 31 drives the first clamping assembly 32 to move along the first direction to drive the wire 7 to move. The first clamping assembly 32 moves between the first position and the second position, so that the pulling length of the wire 7 is limited by the distance between the first position and the second position along the first direction. After the wire 7 is pulled to the required length, the wire 7 is sheared.

[0032] The lap joint 22 is used to press the wire 7 against the cutting plate 21 so that the wire 7 is in a taut state, and the first clamping assembly 32 clamps the wire 7 in a taut state to ensure the consistency of the shear length of the wire 7.

[0033] The wire fixed-length cutting device provided by the utility model presses the wire 7 against the cutting plate 21 through the lap joint 22, so that the wire 7 is in a taut state, so that the first clamping component 32 clamps the wire 7 in the taut state, and drives the first clamping component 32 to move through the first driving component 31 to drive the wire 7 to move, so that the wire 7 is pulled to the required length under the limitation of the distance between the first position and the second position, thereby ensuring the consistency of the shear length of the wire 7.

[0034] In one embodiment of the present invention, the cutting mechanism 2 further comprises a cutting knife 23 disposed on the frame 1 , and the cutting knife 23 is used to move toward or away from the cutting board 21 to cut the wire material 7 on the cutting board 21 .

[0035] For example, the cutting knife 23 and the lap joint 22 are arranged adjacent to each other along the first direction, the second end of the lap joint 22 is arranged close to the cutting knife 23, the first side of the lap joint 22 is the side of the lap joint 22 facing away from the cutting knife 23, and the second side of the lap joint is the side of the lap joint 22 close to the cutting knife 23.

[0036] It can be understood that after the cutting knife 23 cuts the wire 7, the lap joint 22 presses the wire 7 onto the cutting plate 21, so that the wire 7 between the lap joint 22 and the wire roll 51 is in a taut state, and the first clamping component 32 clamps the wire 7 in a taut state at the first position at the starting end, and under the driving action of the first driving component 31, the first clamping component 32 pulls the wire 7, pushes open the lap joint 22 and passes through the lap joint 22, and then moves to the second position at the end, and the cutting knife 23 cuts the wire 7. After the cutting is completed, the first driving component 31 drives the first clamping component 32 to move to the first position to perform the next wire 7 cutting action.

[0037] In one embodiment of the utility model, the cutting device also includes a conveying mechanism 5 arranged on the first side of the overlapping member 22, the conveying mechanism 5 is used to convey the wire 7 to be cut, the conveying mechanism 5 includes a wire roll 51, a connecting member 52 and a second elastic member 53, the first end of the connecting member 52 is connected to the frame 1, the wire roll 51 is rotatably arranged on the connecting member 52, the second elastic member 53 is arranged at the second end of the connecting member 52, and abuts against the side of the wire roll 51 away from the frame 1.

[0038] For example, the connecting member 52 is a fixing screw, and the wire coil 51 is fixed to the frame 1 by the fixing screw. Specifically, the fixing screw is fixedly connected to the frame 1, and the wire coil 51 can rotate around the fixing screw. The second elastic member 53 is a spring, and the second elastic member 53 is used to make the wire coil 51 abut against the frame 1. When the wire coil 51 rotates, friction is generated between the wire coil 51 and the frame 1, and the friction force ensures that the wire 7 is taut.

[0039] In one embodiment of the present invention, the conveying mechanism 5 further comprises a guide assembly, and the guide assembly is arranged between the wire coil 51 and the cutting plate 21 along the conveying direction of the wire 7 .

[0040] Optionally, the guide assembly includes at least one guide component, and the guide component includes two first guide members 54 arranged at intervals, and a guide space for clamping the wire 7 is formed between the two first guide members 54. Of course, the guide assembly may also include at least one second guide member 55.

[0041] Furthermore, the guide assembly may include a guide member and a second guide member 55 at the same time. The number and location of the guide member and the second guide member 55 may be reasonably designed according to actual needs. For example, there may be multiple guide members and the second guide member 55. The guide members and the second guide member 55 may be alternately arranged along the conveying direction of the wire 7. Guide members may also be arranged at both ends between the wire coil 51 and the cutting board 21, and one or more second guide members 55 may be arranged in the middle between the wire coil 51 and the cutting board 21.

[0042] In this embodiment, the guide assembly includes a guide component and two second guide members 55. The guide assembly is arranged adjacent to the cutting board 21 along the first direction, and the two second guide members 55 are arranged between the wire coil 51 and the first guide member 54 along the conveying direction of the wire 7.

[0043] In an embodiment of the present invention, the first driving assembly 31 includes a first slide rail 311 disposed on the frame 1 along a first direction and a first slider 312 disposed on the first slide rail 311 , and the first clamping assembly 32 is disposed on the first slider 312 .

[0044] Specifically, the frame 1 includes a bottom plate 11 and a vertical plate 12 vertically arranged on the bottom plate 11, a first sliding frame is arranged on the bottom plate 11, a first sliding frame is provided with a first slide rail 311 arranged along a first direction, a first slider 312 is arranged on the first slide rail 311, and a first driving member for driving the first slider 312 to move on the first slide rail 311 is also provided on the first sliding frame, and a first clamping assembly 32 is arranged on the first slide. Further, a first guide rod parallel to the first slide rail 311 is provided on the first sliding frame, and the first slider 312 is slidably arranged on the first guide rod. The conveying mechanism 5, the cutting board 21 and the bridging member 22 are all arranged on the first surface of the vertical plate 12, the cutting board 21 is arranged on the upper part of the first surface, and the bridging member 22 is arranged above the cutting board 21. It should be noted here that the first surface of the vertical plate 12 is the surface of the vertical plate 12 close to the first driving assembly 31.

[0045] In one embodiment of the utility model, the first clamping assembly 32 includes a first mounting frame and a first clamping component disposed on the first mounting frame, the first mounting frame is disposed on the first slider 312, and the first clamping component includes two first clamping members 321 disposed opposite to each other along the second direction, and the two first clamping members 321 are suitable for moving toward each other or away from each other along the second direction. It should be noted that the second direction is perpendicular to the first direction. In this embodiment, the first direction X is a horizontal direction, and the second direction Y is a vertical direction.

[0046] The first clamping component is suitable for switching between a first open state and a first clamping state. In the first clamping state, the two first clamping members 321 abut against and are arranged adjacent to the lap joint 22 along the first direction. In the first open state, the two first clamping members 321 are away from each other, and the distance between the two first clamping members 321 satisfies: along the second direction, the cutting board 21 and the lap joint 22 are located between the two first clamping members 321.

[0047] It can be understood that when the first clamping assembly 32 moves from the second position to the first position, the first clamping component is in the first open state, and the first driving member provides power to the first slider 312 to drive the first slider 312 and the first clamping assembly 32 on the first slider 312 to move along the first direction, and the two first clamping members 321 pass through the outside of the cutting board 21 and the lap joint 22 and move to the side of the lap joint 22 away from the cutting board 21, that is, move to the first side of the lap joint 22. At this time, the first clamping assembly 32 moves to the first position. It should be noted here that, when the first clamping component is in the first clamping state, the two first clamping members 321 and the lap joint 22 are arranged side by side along the first direction, and the cutting board 21 limits the lap joint 22 from rotating to the side away from the cutting knife 23, and the lap joint 22 prevents the two first clamping members 321 from moving along the first direction in the first clamping state. Therefore, when the first clamping assembly 32 of this embodiment moves from the second position to the first position, the two first clamping members 321 are in a first open state away from each other, so that the two second clamping members 421 move from the upper and lower sides of the cutting board 21 and the lap joint 22 as a whole.

[0048] It should be noted that when the first clamping assembly 32 is moved from the first position to the second position, since the lap joint 22 is rotatably arranged on the frame 1, the lap joint 22 can be rotated toward the side close to the cutting knife 23, so that the two first clamping members 321 in the first clamping state and clamping the wire 7 are driven by the first driving member to push open the lap joint 22 and pass through the lap joint 22 to move to the second position, so as to pull the wire 7 of the required length, and then the wire 7 is cut by the cutting knife 23.

[0049] In a preferred embodiment of the utility model, the cutting device also includes a second clamping mechanism, which includes a second driving assembly 41 arranged on the frame 1 and a second clamping assembly 42 arranged on the second driving assembly 41. The second driving assembly 41 is used to drive the second clamping assembly 42 to move between a third position and a fourth position. In the third position, the second clamping assembly 42 is located between the lap joint 22 and the first clamping assembly 32 along the first direction. In the fourth position, the second clamping assembly 42 moves out from between the lap joint 22 and the first clamping assembly 32.

[0050] It can be understood that after the first clamping assembly 32 clamps the wire 7 at the first position and moves from the first position to the second position, the second clamping assembly 42 is located at the third position between the lap joint 22 and the first clamping assembly 32, and the wire 7 between the lap joint 22 and the first clamping assembly 32 is clamped by the second clamping assembly 42, the first clamping assembly 32 is opened, and the cutting knife 23 performs a cutting action, and then the second driving assembly 41 drives the second clamping assembly 42 to move out from between the lap joint 22 and the first clamping assembly 32 and reach the fourth position to move the cut wire 7 past the predetermined position.

[0051] Optionally, the second drive assembly 41 and the first drive assembly 31 are respectively located on both sides of the vertical plate 12, and the second drive assembly 41 is arranged on the second surface of the vertical plate 12. The second drive assembly 41 can adopt the same structure as the first drive assembly 31, or can adopt other drive structures, such as a hydraulic drive structure or a cylinder drive structure. For example, the second drive assembly 41 drives the second clamping assembly 42 to move between the third position and the second position along the second direction Y, i.e., the vertical direction.

[0052] Furthermore, the second clamping assembly 42 includes a second mounting frame and a second clamping component arranged on the second mounting frame, the second mounting frame is arranged on the second driving assembly 41, the second clamping component includes two second clamping members 421 arranged opposite to each other along the second direction, and the second clamping component is suitable for switching between the second open state and the second clamping state.

[0053] When the second clamping component is in the third position and in the second clamping state, the second clamping component 421 and the first clamping component 321 are arranged side by side along the first direction, and when the second clamping component is in the third position and in the second open state, the distance between the two second clamping components 421 is greater than the distance between the two first clamping components 321 in the first open state, so as to provide avoidance space for the two first clamping components 321 in the first open state to move from the second position to the first position.

[0054] In one embodiment of the present invention, the cutting mechanism 2 also includes a third drive assembly 24, the third drive assembly 24 is arranged on the frame 1, and the cutting knife 23 is arranged on the third drive assembly 24, and the third drive assembly 24 is used to drive the cutting knife 23 to move toward or away from the cutting plate 21 along the second direction.

[0055] For example, the third driving assembly 24 is arranged on the second surface of the vertical plate 12, and the third driving assembly 24 includes a driving component arranged on the vertical plate 12 and a moving member 241 arranged at the output of the driving component. The cutting knife 23 is arranged on the moving member 241, and the driving component drives the moving member 241 to move up and down to drive the cutting knife 23 to move up and down.

[0056] Furthermore, the cutting knife 23 is connected to the moving member 241 via a first elastic member 242 . The first elastic member 242 may be a spring. The first elastic member 242 plays a buffering role to protect the cutting knife 23 and extend the service life of the cutting knife 23 .

[0057] In another embodiment of the utility model, it also includes a wire detection sensor 6 arranged on the frame 1, and the wire detection sensor 6 is used to detect the wire 7 between the first position and the second position, so as to detect whether the first clamping assembly 32 drives the wire 7 to move synchronously during the movement of the first clamping assembly 32 from the first position to the second position along the first direction, so that the wire 7 is pulled to a required length.

[0061] The guide assembly includes a guide component and two second guide components 55. The guide component includes two first guide components 54 arranged at intervals on the upper part of the vertical plate 12.

[0066] The working principle of the wire length cutting device in the embodiment of the utility model is as follows: in the initial state, the first clamping component 32 is located at the second position, the first clamping part is in the first clamping state, the second clamping component 42 is located at the third position, and the second clamping part is in the second clamping state.

[0067] The wire 7 on the wire coil 51 passes through the second guide member 55 and the first guide member 54 and then passes through the lower end of the bridging member 22 , and the wire 7 is pressed against the cutting board 21 by the bridging member 22 .

[0068] Open the first clamping member and the second clamping member so that the first clamping member is in the first open state and the second clamping member is in the second open state. The first driving member provides power to the first slider 312 to drive the first slider 312 and the first clamping member fixed on the first slider 312 to move to the left side, so that it passes over the second clamping member 421, the cutting plate 21, the cutting knife 23 and the lap joint 22 and moves to the first position, that is, reaches the left end of the lap joint 22.

[0069] The first clamping component is closed to clamp the wire 7. The first driving member provides power to the first slider 312 to drive the first slider 312 and the first clamping component fixed on the first slider 312 to move to the right, pulling the wire 7 to move together, and after being pushed open and passing through the lap joint 22 in turn, the lower end of the lap joint 22 sags due to gravity, pressing the wire 7 onto the cutting board 21, and passing through the cutting knife 23 in turn, and the second clamping component in the open state moves to the second position, that is, reaching the set end.

[0070] The second clamping component is closed to clamp the wire 7 ; the first clamping component is opened to release the wire 7 .

[0071] The third driving assembly 24 provides power to drive the moving member 241 and the cutting knife 23 installed on the moving member 241 to move downward, so as to cut the wire 7 attached to the cutting plate 21 .

[0072] The second driving assembly 41 provides power to drive the second clamping assembly 42 to move from the third position to the predetermined fourth position. After removing the wire 7 on the second clamping assembly 42, the second driving assembly 41 returns the second clamping assembly 42 to the third position, thereby completing the cutting of the fixed-length wire 7.

[0073] The wire fixed length cutting device provided by the utility model is fixed by one end of the lap joint 22, and the other end falls freely on the cutting board 21 by gravity, and forms a certain angle with the cutting board 21. When the first clamping part passes through, the lap joint 22 is pushed open, and after passing through, the free end of the lap joint 22 can press the wire 7 on the cutting board 21 by its own weight, which is convenient for grabbing the wire 7 next time, so as to automatically realize the fixed length cutting of the rolled wire 7. In addition, the entire cutting process is realized without human participation, eliminating errors caused by human factors, reducing labor intensity, ensuring the consistency of cutting length, and thus ensuring the reliability of test data.
