Description

Technical Field

[0001] This utility model relates to the field of wire harness cutting technology, specifically to a manual core wire cutting device. Background Technology

[0002] For some core wires in the workshop that cannot be cut using equipment (such as high-voltage 5-core wires), manual cutting is required. The main tools for manual cutting are diagonal pliers, ratchet cable cutters, etc. However, most of them rely on the palm of the hand to apply force and rely on grip strength to complete the cutting. However, these tools are inefficient and cannot be used for batch cutting operations. Utility Model Content

[0003] The purpose of this utility model is to provide a manual core wire cutting device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A manual wire cutting device includes a base plate, a mounting plate mounted on the base plate, a mounting seat mounted on the mounting plate, a pull rod hinged to the mounting seat, a pressure handle hinged to the free end of the pull rod, a guide rod vertically sliding on the mounting plate, a mounting block constructed on the guide rod, the end of the pressure handle hinged to the mounting block, a knife holder mounted at the end of the guide rod, and a double-edged knife mounted on the knife holder.

[0006] Furthermore, the substrate is provided with a blade groove located below the double-edged blade.

[0007] Furthermore, the substrate has a movable through hole, and two strips are hinged to the substrate. Each strip has a pressure wheel rotatably mounted on one end, and the other ends of the two strips pass through the movable through hole. They rotate synchronously under a drive so that the pressure wheels move closer to or further away from each other.

[0008] Furthermore, a rubber sleeve is fitted on the outer side of the clamping wheel.

[0009] Furthermore, a slide rod is installed on the back side of the mounting plate, and two synchronously moving sliders are slidably mounted on the slide rod. A strip-shaped hole is constructed at the end of the plate, and a column is constructed on the slider. The column is inserted into the strip-shaped hole and is tangent to it.

[0010] Furthermore, the mounting plate is provided with a motion hole, and a connecting rod is installed on the tool holder. One end of the connecting rod passes through the motion hole and is located on the back side of the mounting plate. A linkage plate is installed at the end of the connecting rod, and a connecting rod is hinged between the linkage plate and the two sliders.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention uses a force-saving lever mechanism to drive the movement of the cutter holder, and the entire force is guided by the arm, rather than by the gripping force of the palm. Therefore, it is easier to complete the core wire cutting work during operation, thereby helping to improve the core wire cutting efficiency. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figures 1-3As shown in the figure, an embodiment of the present invention provides a manual core wire cutting device, including a base plate 1. A mounting plate 2 is mounted on the base plate 1. The mounting plate 2 is generally L-shaped, with its horizontal section assembled to the base plate 1 by bolts and its vertical section perpendicular to the base plate 1. A mounting seat 5 is mounted on the mounting plate 2 and is bolted to the vertical section. A pull rod 6 is hinged to the mounting seat 5, and a pressure handle 7 is hinged to the free end of the pull rod 6. The hinge point between the pull rod 6 and the pressure handle 7 is near one end of the pressure handle 7, which is defined here as the first end. A guide rod 8 slides vertically on the mounting plate 2, and a mounting block is constructed on the guide rod 8. 9. The end of the pressure handle 7 is hinged to the mounting block 9. The hinge position here is the first end of the pressure handle 7. Based on the above structure, it can be seen that when the other end of the pressure handle 7 is pressed, which can be defined as the second end, the pressure handle 7 will rotate around the hinge point with the pull rod 6. At this time, the first segment position moves downward, thereby driving the mounting block 9 and the guide rod 8 to move downward. Pulling will swing around the hinge point with the mounting base 5. A fixing plate 10 is installed on the vertical segment. The guide rod 8 slides with the fixing plate 10. In order to complete the cutting operation of the core wire, a knife holder 3 is installed at the end of the guide rod 8. A double-edged knife 4 is installed on the knife holder 3. The double-edged knife 4 cuts the core wire.

[0019] In summary, this utility model uses a force-saving lever mechanism to drive the movement of the cutter holder 3, and the entire force is guided by the arm, rather than by the gripping force of the palm to complete the use of the device. Therefore, it is easier to complete the core wire cutting work during operation, thereby helping to improve the core wire cutting efficiency.

[0020] like Figure 1 As shown, in some embodiments, the substrate 1 is provided with a blade groove 11 located below the double-edged blade 4. During the cutting of the core wire, part of the structure of the double-edged blade 4 can enter the blade groove 11, thereby cutting the core wire more completely and avoiding the double-edged blade from directly contacting the substrate 1 and causing wear at the blade edge. It should be noted that the double-edged blade 4 does not completely touch the bottom when it enters the blade groove 11.

[0021] like Figures 1-3 As shown, in order to improve the stability of the core wire during the cutting process and prevent movement, in some embodiments, the substrate 1 is provided with a movable through hole 12, and two strips 13 are hinged to the substrate 1. Each strip 13 has a pressure wheel 14 rotatably mounted on one end, and the other end of each strip 13 passes through the movable through hole 12. They rotate synchronously under drive so that the pressure wheels 14 move closer or further away from each other. When the two strips 13 rotate around the hinge point, they can drive the two pressure wheels 14 to move closer to each other and press on the core wire, thereby squeezing the core wire and fixing it. In this way, when the double-edged blade 4 contacts the core wire and cuts it, it can prevent the core wire from moving randomly and causing cutting deviation.

[0022] like Figure 3 As shown, in some embodiments, a rubber sleeve 15 is fitted around the outer side of the clamping wheel 14. The rubber sleeve 15 is used to increase the friction with the surface of the core wire. The clamping wheel 14 and the strip 13 are rotatably connected, and the strip 13 moves in an arc. So, when the clamping wheel 14 is in contact with the core wire in an arc, if it cannot rotate, it will inevitably push the core wire to move. However, by adopting a rotating design, the amplitude of pushing the core wire to move is reduced, and the clamping wheel 14 rotates on its own. However, in order to improve the fixing effect on the core wire, the friction is increased by the rubber sleeve 15.

[0023] like Figures 1-3 As shown, in order to achieve synchronous rotation of the two strips 13, in some embodiments, a slide rod 16 is installed on the back side of the mounting plate 2. The slide rod 16 is slidably mounted with two synchronously moving sliders 17. The end of the strip 13 is constructed with a strip-shaped hole 18. A column rod 19 is constructed on the slider 17. The column rod 19 is inserted into the strip-shaped hole 18 and is tangent to it. Based on the above disclosure, it can be seen that when the two sliders 17 move synchronously, they will inevitably drive the column rod 19 to move in the strip-shaped hole. Since the column rod 19 moves in a straight line, it will push the strip 13 to move in an arc around the hinge point. In this process, the position of the pressure wheel 14 can be moved.

[0024] Considering that this utility model is a manual device, the moving structure of the drive slider 17 should avoid the use of electrical power components. Furthermore, to reduce operational complexity, no additional operations besides the shearing operation should be added. Therefore, in this utility model, the mounting plate 2 has a motion hole 21, and the cutter holder 3 is equipped with a connecting rod 22. One end of the connecting rod 22 passes through the motion hole 21 and is located on the back side of the mounting plate 2. A linkage plate 20 is installed at the end of the connecting rod 22. The linkage plate 20 is hinged to both sliders 17. Rod 23, in other words, when the double-edged blade 4 moves downward to cut the core wire, it will simultaneously drive the linkage plate 20 to move downward, and through the two connecting rods 23, drive the two sliders 17 to move, thereby fixing the core wire with the two clamping rollers 14. It should be noted that when the double-edged blade 4 just contacts the core wire, the two clamping rollers 14 have already completed the fixing of the core wire. However, due to the presence of the rubber sleeve 15, as the double-edged blade 4 continues to move downward, it drives the clamping rollers 14 to move closer and closer to the core wire. At this time, the deformation of the rubber sleeve 15 can prevent excessive compression of the core wire.

[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
