Description

Technical Field

[0001] The invention belongs to the technical field of wire cutting equipment, and in particular relates to a wire cutting device for producing wire groups. Background Art

[0002] A wire assembly is an electrical system component composed of multiple wires, connectors, terminals, plugs and other components. It is used to transmit electrical signals or electrical energy from one point to another. Wire assemblies play the role of connecting, conducting and transmitting signals in various electrical equipment and automation systems. They are widely used in automobiles, home appliances, industrial equipment, computers and other fields. However, during the production process of wire assemblies, the wires need to be cut by cutting equipment to cut the entire wire into multiple sections to meet different length requirements. Many wire applications have specific requirements for the length of the wires, such as home appliances, electrical equipment, automotive electrical systems, etc. Cutting the wires into multiple sections during the production process can meet the length requirements of different customers and applications and avoid waste.

[0003] Existing wire cutting methods are generally divided into two types: one is to use automated equipment to cut the wires, and the wire is transported by the wire-releasing mechanism. When the wires are transported to the cutting mechanism, the cutting knife shears them to achieve automatic cutting. When wires of different lengths need to be cut, the design data parameters are adjusted to automatically cut wires of different lengths. However, this type of equipment requires the use of multiple driving mechanisms, and the subsequent maintenance cost is high. The other type of manual cutting is to manually cut the wires of different lengths, but this method is inefficient. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a wire cutting device for producing wire groups.

[0005] The technical solution adopted to solve the above technical problems is: a wire cutting device for producing wire groups, comprising a bottom plate, a wire release mechanism is installed on one side of the top of the bottom plate, and a wire feeding mechanism is installed at the top center of the bottom plate;

[0006] The other side of the top of the bottom plate is fixedly connected to a chassis near the wire feeding mechanism, a cutting mechanism is installed in the chassis, and the top of the bottom plate is fixedly connected to a support frame near the front end of the chassis;

[0007] The top rear end of the support frame is fixedly connected with a protection box, a linkage mechanism is installed in the protection box, the top front end of the support frame is installed with a driving mechanism, and a material receiving box is provided on the other side of the top of the base plate near the chassis.

[0008] Furthermore, the wire-releasing mechanism comprises a chassis fixedly connected to one side of the top of the bottom plate, the top of the chassis is rotatably connected to a wire-releasing frame, and the wire body is wound on the wire-releasing frame.

[0009] Through the above technical solution, when the wire body is cut, the wire feeding mechanism drives the wire body to be transported to one end, and the wire pay-off frame is rotated on the chassis through the pulling force, and the wire body is automatically paid out.

[0010] Furthermore, the wire feeding mechanism includes a mounting frame fixedly connected to the top center of the base plate, a plurality of wire wheels are installed on one side of the front end of the mounting frame, a connecting frame is fixedly connected to the other side of the front end of the mounting frame, a driving shaft and a driven shaft are rotatably connected between the mounting frame and the connecting frame, the outer walls of the driving shaft and the driven shaft are fixedly connected to the wire feeding wheels, and the front end of the outer wall of the driving shaft is fixedly connected to the first synchronous wheel.

[0011] Through the above technical solution, when the wire body is fed, the rotation of the first synchronous wheel drives the driving shaft to rotate, so that the driving shaft drives the connected wire feeding wheel to rotate. Since there is friction between the two wire feeding wheels, the wire body is evenly transported during the rotation process, so that the wire body passes through multiple wire wheels, and the wire body is straightened, which is convenient for subsequent cutting.

[0012] Furthermore, the front and rear ends of the top center of the chassis are fixedly connected to two fixing seats, and limiting wheels are installed on the tops of the two fixing seats. A guide frame is fixedly connected to one side of the top of the chassis, and the two limiting wheels are used to limit the corresponding tool holders.

[0013] Through the above technical solution, the cut section of the wire body is supported by the guide frame to prevent the cutting position of the wire body from being in a bent state during cutting, thereby improving the cutting accuracy. At the same time, the arc surface on one side of the guide frame is used to guide the end face of the wire body, and the arc surface on the other side of the guide frame is used to discharge the cut wire body and drop it accurately into the receiving box.

[0014] Furthermore, the cutting mechanism includes a first rotating shaft rotatably connected to the center of the chassis, a rotating wheel is fixedly connected to the outer wall of the first rotating shaft, a wire groove is opened in the center of the outer wall of the rotating wheel, an installation groove is opened on the outer wall of the rotating wheel, two connecting shafts are fixedly connected to one side of the outer end surface of the installation groove, the bottom ends of the outer walls of the two connecting shafts are rotatably connected to knife seats, one end of the two knife seats is equipped with a cutting knife, the top ends of the outer walls of the two connecting shafts are rotatably connected to rubber wheels, a spring is fixedly connected between the two knife seats, the front and rear ends of the rotating wheel are respectively fixedly connected to fixing ears close to the installation groove, and the inner end surfaces of the two fixing ears are fixedly connected to protrusions.

[0015] Through the above technical scheme, when the wire body is being transported, the first rotating shaft rotates at the same time to drive the rotating wheel to rotate, thereby driving the two knife seats to rotate, so that the two knife seats rotate until they are in contact with the two limiting wheels respectively. When the rotating wheel continues to rotate, the two knife seats are limited by the corresponding limiting wheels, so that the two knife seats rotate toward each other, and respectively drive the connected cutting knives to move toward each other to achieve cutting of the wire body. After cutting, under the action of the spring, the two knife seats are reset and fit with the corresponding protrusions to facilitate cutting of the next section of the wire body. When the rotating wheel is rotating and before the two cutting knives cut the wire body, the two rubber wheels just clamp the wire body through the rubber elastic force. When the two cutting knives cut the wire body, the cutting position of the wire body is prevented from bending, thereby improving the cutting accuracy of the wire body and thus improving the cutting quality.

[0016] Furthermore, the two protrusions are fitted with the corresponding tool seats.

[0017] Through the above technical solution, when the electric wire body is cut, the electric wire body passes through the wire groove and is limited, thereby improving the cutting quality.

[0018] Furthermore, the linkage mechanism includes a first rotating cylinder rotatably connected to the rear end of one side of the protective box, a second rotating cylinder rotatably connected to the front end of one side of the protective box, two limit grooves are provided on the inner walls of the first rotating cylinder and the second rotating cylinder, a second rotating shaft is slidably connected between the first rotating cylinder and the second rotating cylinder, and two limit bars are fixedly connected to the outer wall of the second rotating shaft, a first gear is rotatably connected to the outer wall of the first rotating cylinder, a second gear is rotatably connected to the outer wall of the second rotating cylinder, a plurality of limit shafts are fixedly connected to the front end of the first rotating cylinder and the rear end of the second rotating cylinder, a third gear is fixedly connected to the outer wall of the second rotating shaft, a third rotating shaft is rotatably connected to the other side of the protective box, a fourth gear, a fifth gear and a sixth gear are fixedly connected to the outer wall of the third rotating shaft, a second synchronous wheel is fixedly connected to the rear end of the outer wall of the third rotating shaft, and a synchronous belt is sleeved between the second synchronous wheel and the first synchronous wheel.

[0019] By means of the above technical scheme, when the rotation speed of the wire feeding wheel is greater than the rotation speed of the rotating wheel, the length of the wire body being cut becomes longer, and when the rotation speed of the wire feeding wheel is less than the rotation speed of the rotating wheel, the length of the wire body being cut becomes shorter. Before adjustment, the rotation of the second shaft drives the third gear to rotate, and the rotation of the third gear drives the meshing fifth gear to rotate, so that the fifth gear drives the third shaft to rotate, and the third shaft drives the second synchronous wheel to rotate, and with the cooperation of the synchronous belt, drives the first synchronous wheel to rotate, thereby driving the connected wire feeding wheel to rotate, so as to realize the transportation of the wire body. When the cutting length of the wire body needs to be adjusted, the third gear moves to the rear end, so that the multiple limit shafts on the first gear are inserted into the tooth grooves on the third gear, and the rotation of the third gear drives the first gear to rotate, and the rotation of the first gear drives the fourth gear to rotate. Since the first gear is larger than the fourth gear, Four gears make the fourth gear rotate faster, thereby increasing the rotation speed of the wire feeding wheel, and further improving the conveying efficiency of the wire body. Since the central axes of the first gear, the third gear and the rotating wheel are all connected, the rotation speeds are the same, and finally the cutting length of the wire body becomes longer. Similarly, when the third gear moves to the front end, the multiple limit shafts on the second gear are inserted into the tooth grooves on the third gear. The rotation of the third gear drives the second gear to rotate, and the rotation of the second gear drives the sixth gear to rotate, so that the two wire feeding wheels adjust the conveying efficiency of the wire body, which can be adjusted to different lengths. It has strong functionality. When the rotating wheel is rotating, and the wire feeding mechanism conveys the wire body, the entire equipment is carried out simultaneously in the cutting and conveying processes, reducing the response time of each mechanism and greatly improving work efficiency.

[0020] Furthermore, the rear end of the first rotating drum is fixedly connected to the front end of the first rotating shaft through a coupling, the two limit bars are respectively slidably connected to the corresponding limit grooves, the first gear is meshed with the fourth gear, the second gear is meshed with the sixth gear, the third gear is meshed with the fifth gear, the fifth gear is located at the front end of the fourth gear, and the sixth gear is located at the front end of the fifth gear.

[0021] Through the above technical solution, the rotation of the second rotating shaft drives the two limit bars to rotate, thereby driving the first rotating drum and the second rotating drum to rotate. Since the first gear and the second gear are rotationally connected to the first rotating drum and the second rotating drum respectively, when the first rotating drum and the second rotating drum rotate, the meshing of the first gear and the fourth gear and the meshing of the second gear and the sixth gear will not be affected.

[0022] Furthermore, the driving mechanism includes a frame slidably connected to the top center of the support frame, a motor is fixedly installed on the top of the frame, the rear end of the motor output shaft is fixedly connected to the front end of the second rotating shaft, the top front end of the frame is fixedly connected to a fixing frame, a cylinder is fixedly installed on the fixing frame, and the rear end of the cylinder piston is fixedly connected to the frame.

[0023] Through the above technical solution, when the entire equipment is running, the motor is started, so that the motor drives the second rotating shaft to rotate through the output shaft, so that the second rotating shaft drives the first rotating drum to rotate, thereby driving the first rotating shaft to rotate, thereby driving the cutting mechanism. At the same time, the rotation of the second rotating shaft realizes the driving of the linkage mechanism. When the length of the cut wire body needs to be adjusted, the cylinder is started, so that the cylinder pushes the fixed frame and the motor through the piston, so that the motor pushes the second rotating shaft through the output shaft, thereby pushing the third gear. Similarly, the third gear can be contracted by the cylinder to adjust another length of the wire body cut.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs a wire feeding mechanism, a cutting mechanism, a linkage mechanism and a driving mechanism, so that the device can transport and cut the wires through a motor, which not only has a low cost of use, but also greatly reduces the subsequent maintenance cost. In addition, there is no need to wait for signal responses between the various mechanisms, which greatly improves the cutting efficiency. (2) The present invention designs a linkage mechanism and a driving mechanism, and the linkage mechanism can be adjusted by the driving mechanism to adjust the cutting length of the wire. Since the rotation speed of the cutting mechanism is fixed, the rotation speed of the feeding mechanism is changed to achieve the adjustment of the cutting length of the wire. At the same time, different lengths can be adjusted, and the functionality is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figure 1-Figure 7As shown, a linkage mechanism 8 is installed in the protection box 7, and the linkage mechanism 8 includes a first rotating cylinder 801 rotatably connected to the rear end of one side of the protection box 7, and a second rotating cylinder 802 is rotatably connected to the front end of one side of the protection box 7. Two limiting grooves 803 are provided on the inner walls of the first rotating cylinder 801 and the second rotating cylinder 802. A second rotating shaft 804 is slidably connected between the first rotating cylinder 801 and the second rotating cylinder 802. Two limiting strips 805 are fixedly connected to the outer wall of the second rotating shaft 804. A first gear 806 is rotatably connected to the outer wall of the first rotating cylinder 801, and a second gear 807 is rotatably connected to the outer wall of the second rotating cylinder 802. A plurality of limiting shafts 808 are fixedly connected to the front end of the first rotating cylinder 801 and the rear end of the second rotating cylinder 802.

Since the central axes of the first gear 806, the third gear 809 and the rotating wheel 502 are all connected, the rotation speeds are the same, and finally the cutting length of the wire body 203 becomes longer. Similarly, when the third gear 809 moves toward the front end, the multiple limit shafts 808 on the second gear 807 are inserted into the tooth grooves on the third gear 809.

The second rotating shaft 804 rotates to drive the two limiting bars 805 to rotate, thereby driving the first rotating drum 801 and the second rotating drum 802 to rotate. Since the first gear 806 and the second gear 807 are respectively rotatably connected to the first rotating drum 801 and the second rotating drum 802, when the first rotating drum 801 and the second rotating drum 802 rotate, the meshing of the first gear 806 and the fourth gear 811 and the meshing of the second gear 807 and the sixth gear 813 will not be affected. ,

At the same time, the rotation of the second rotating shaft 804 realizes the driving of the linkage mechanism 8. When it is necessary to adjust the length of the cut wire body 203, the cylinder 904 is started, so that the cylinder 904 pushes the fixed frame 903 and the motor 902 through the piston, so that the motor 902 pushes the second rotating shaft 804 through the output shaft, thereby pushing the third gear 809. Similarly, the third gear 809 can be contracted by the cylinder 904 to adjust another length of the wire body 203 cut.

[0042] At the same time, the second rotating shaft 804 drives the first rotating drum 801 to rotate, thereby driving the first rotating shaft 501 to rotate. The rotation of the first rotating shaft 501 drives the rotating wheel 502 to rotate. The rotation of the rotating wheel 502 drives the two rubber wheels 508 to clamp the outer wall of the wire body 203, and at the same time drives the two knife seats 506 to rotate, so that the two knife seats 506 rotate to contact with the two limiting wheels 42 respectively. When the rotating wheel 502 continues to rotate, the two knife seats 506 are limited by the corresponding limiting wheels 42, so that the two knife seats 506 rotate towards each other, respectively drive the connected cutting knives 507 to move towards each other, and realize cutting of the wire body 203. The cut wire body 203 falls into the material receiving box 10. After cutting, the rotating wheel 502 continues to rotate. Under the action of the spring 509, the two knife seats 506 are reset and fit with the corresponding protrusions 511, which is convenient for cutting the next section of the wire body 203.

[0043] When the cutting length of the wire body 203 needs to be adjusted, the cylinder 904 is started, so that the cylinder 904 pushes the fixing frame 903 and the motor 902 through the piston, so that the motor 902 pushes the second rotating shaft 804 through the output shaft, thereby pushing the third gear 809, so that the multiple limit shafts 808 on the first gear 806 are inserted into the tooth grooves on the third gear 809, and the rotation of the third gear 809 drives the first gear 806 to rotate, and the rotation of the first gear 806 drives the fourth gear 811 to rotate. Since the first gear 806 is larger than the fourth gear 811, the rotation speed of the fourth gear 811 becomes faster, thereby increasing the rotation speed of the wire feeding wheel 306, and performing In order to improve the conveying efficiency of the wire body 203, since the central axes of the first gear 806, the third gear 809 and the rotating wheel 502 are all connected, the rotation speeds are the same, and finally the cutting length of the wire body 203 becomes longer. Similarly, when the third gear 809 moves toward the front end, the multiple limit shafts 808 on the second gear 807 are inserted into the tooth grooves on the third gear 809. The rotation of the third gear 809 drives the second gear 807 to rotate, and the rotation of the second gear 807 drives the sixth gear 813 to rotate, so that the two wire feeding wheels 306 can adjust the conveying efficiency of the wire body 203 and can be adjusted to different lengths.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
