Description
Technical Field
[0001] This invention relates to the field of cutting machines, and more particularly to a metal wire cutting machine with a single wire-collecting roller. Background Technology
[0002] A wire EDM machine is a device used for the precise cutting of sheet metal materials, commonly used in industries such as metal processing and manufacturing, mechanical automation, and automotive. The basic structure of a traditional wire EDM machine includes components such as a wire feed roller, a cutting wire, rollers, and a control system. Traditional wire EDM machines use a thin wire as the cutting tool, cutting the material through pulsed electrical discharges during high-speed wire drawing. The cutting wire is typically made of molybdenum alloy, which has high conductivity. During the cutting process, the cutting wire is taut with the rollers as support points; the upper and lower rollers are perpendicular and close to the metal material to be processed, performing pulsed electrical discharges for cutting. However, traditional wire EDM machines have some drawbacks.
[0003] Traditional wire cutting machines use a method where the cutting wire wraps around one side of two rollers, preventing the rollers from moving independently. Therefore, when cutting a product, cutting can only be done by moving the product itself, not the cutting machine. This restricts the flexibility of adjusting the cutting position during the process. This limitation makes traditional wire cutting machines ill-suited for cutting large and complex parts, and also fails to meet the current urgent demand for intelligent and automated processes.
[0004] This invention aims to provide an improved wire cutting machine that addresses the problems of traditional wire cutting machines by introducing a new structure. The improved wire cutting machine adopts a gantry-type design structure with independent movement functions for the upper and lower rollers, enabling flexible adjustment of the cutting equipment and adapting to the cutting needs of large parts, thus providing a structural foundation for the intelligent and automated development of cutting equipment.
[0005] Metal wire cutting machines are divided into single-wire roller and double-wire roller types. This invention is aimed at metal wire cutting machines with single-wire rollers. Summary of the Invention
[0006] The technical problem to be solved by the present invention is to provide a metal wire cutting machine for a single wire-collecting roller. During cutting, the metal wire in the cutting area can be freely displaced by moving two independently movable rollers, without the need for moving equipment, and the cutting position can be flexibly adjusted.
[0007] The technical solution adopted by this invention to solve the above-mentioned technical problems is a metal wire cutting machine with a single wire-collecting roller, including a motor, a control system, a wire-collecting roller, and a fixed roller assembly. A metal wire is sleeved on the outside of the wire-collecting roller and the fixed roller. The fixed roller assembly includes a first fixed roller. A cutting area is formed between the wire-collecting roller and the first fixed roller. A second displacement roller and a third displacement roller are also arranged within the cutting area. The first displacement roller and the second displacement roller move synchronously laterally. The first displacement roller is positioned above the second displacement roller. The first displacement roller and the wire-collecting roller are connected by a first metal wire, which is positioned above both. The second displacement roller and the first fixed roller are connected by a second metal wire, which is positioned below both. The first displacement roller and the second displacement roller are connected by a third metal wire, which is positioned on opposite sides of the first and second displacement rollers. The first metal wire, the second metal wire, and the third metal wire form a Z-shaped metal wire.
[0008] A further preferred embodiment of the present invention is that the upper ends of the first displacement roller and the wire collecting roller are at the same height, so that the first metal wire is in the horizontal direction.
[0009] A further preferred embodiment of the present invention is that the lower ends of the second displacement roller and the first fixed roller are at the same height, so that the second metal wire is in the horizontal direction.
[0010] A further preferred embodiment of the present invention is that the opposite sides of the first displacement roller and the second displacement roller are on the same vertical line, so that the third metal wire is perpendicular to the direction.
[0011] A further preferred embodiment of the present invention is that the fixed roller assembly further includes a second fixed roller and a third fixed roller, the second fixed roller being disposed above the first fixed roller and the third fixed roller being disposed above the wire collecting roller.
[0012] A further preferred embodiment of the present invention is that the wire collecting roller is provided with a wire hook for fixing the metal wire.
[0013] A further preferred embodiment of the present invention is that the end of the metal wire is connected to a flexible wire.
[0014] A further preferred embodiment of the present invention is that the upper part of the wire hook is a flared opening, and the lower part of the wire hook is a vertical slit.
[0015] This invention features a first and second displacement roller within the cutting area. A metal wire is looped around the opposite sides of the first and second displacement rollers. A first metal wire is positioned between a wire-collecting roller and the first displacement roller; a second metal wire is positioned between a first fixed roller and the second displacement roller; and a third metal wire is positioned between the first and second displacement rollers. These three metal wires combine to form a Z-shaped structure. When the first and second displacement rollers move simultaneously, the third metal wire moves accordingly. Due to the unique structure of this invention, the circumference formed by the metal wire remains constant, thus not affecting the operation of the equipment. The third metal wire can cut the part after moving without moving the part itself, making the cutting more flexible. This allows for intelligent and automated adjustments to the subsequent cutting equipment to adapt to the overall cutting and processing needs of large and complex parts. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0023] like Figure 1 As shown, a traditional wire cutting machine typically includes a wire-collecting roller 4 and multiple fixed rollers 20, with the metal wire 3 wrapped around the fixed rollers 20. The distribution of the fixed rollers 20 and the metal wire 3 means that the fixed rollers cannot be moved. If they were moved, the circumference of the surrounding metal wire would change, causing the metal wire 3 to detach from the fixed rollers 20. Therefore, a traditional wire cutting machine can only change its position by moving the component 21 itself, and cannot adjust the cutting position by moving the fixed rollers.
[0024] like Figure 2 , Figure 5 , Figure 6As shown, this invention adds a first displacement roller 1 and a second displacement roller 2 to a traditional metal cutting machine. A metal wire 3 is fitted onto the opposite sides of the first and second displacement rollers 1 and 2. A first metal wire 5 is positioned between the wire-collecting roller 4 and the first displacement roller 1. A second metal wire 7 is positioned between the first fixed roller 6 and the second displacement roller 2. A third metal wire 8 is positioned between the first and second displacement rollers 1 and 2. The three metal wires 3 are combined to form a Z-shaped metal wire structure. When the first and second displacement rollers 1 and 2 move simultaneously, the third metal wire 8 moves accordingly. Due to the special structure of this invention, the circumference formed by the metal wires 3 remains unchanged, thus not affecting the operation of the equipment. After the third metal wire 8 moves, it can cut the part 21 without moving the part 21 itself. To be applicable to different types of cutting machines, this invention has developed two different specific implementation methods. This invention mainly introduces the technical solution applied to a single wire-collecting roller.
[0025] A metal wire 3 cutting machine suitable for a single wire-collecting roller 4. A novel metal wire 3 cutting machine includes a motor, a control system, a wire-collecting roller 4, and a fixed roller assembly. The motor drives the wire-collecting roller 4 to rotate, and the control system controls the rotation speed and direction of the motor. The metal wire 3 is sleeved on the outside of the wire-collecting roller 4 and the fixed roller assembly. The fixed roller assembly includes a first fixed roller 6, a second fixed roller 9, and a third fixed roller 10. The wire-collecting roller 4 and the first fixed roller 6 form a cutting area, and the cutting activity is carried out on the metal wire within the cutting area. A first displacement roller 1 and a second displacement roller 2 are also provided within the cutting area. The first displacement roller 1 and the second displacement roller 2 move synchronously laterally, with the first displacement roller 1 positioned above the second displacement roller 2. The first displacement roller 1 and the wire-collecting roller 4 are connected by a first metal wire 5, and the first metal wire 5 is positioned above the first displacement roller 1 and the wire-collecting roller 4. The upper ends of the first displacement roller 1 and the wire-collecting roller 4 are at the same height, so that the first metal wire 5 is in a horizontal direction. The second displacement roller 2 and the first fixed roller 6 are connected by a second metal wire 7, which is positioned below both the second displacement roller 2 and the first fixed roller 6. The lower ends of the second displacement roller 2 and the first fixed roller 6 are at the same height, making the second metal wire 7 horizontal. The first displacement roller 1 and the second displacement roller 2 are connected by a third metal wire 8, which is positioned on opposite sides of the first displacement roller 1 and the second displacement roller 2. The opposite sides of the first displacement roller 1 and the second displacement roller 2 are on the same vertical line, but the first displacement roller 1 and the second displacement roller 2 are not entirely on a vertical line, exhibiting a certain degree of skewness, ultimately making the third metal wire 8 vertical. The first metal wire 5, the second metal wire 7, and the third metal wire 8 form a Z-shaped metal wire 3. The first metal wire 5, the second metal wire 7, and the third metal wire 8 do not need to be completely horizontal or vertical; their angles can be adjusted as needed. Since the first displacement roller 1 and the second displacement roller 2 do not cause a change in the circumference of the metal wire 3 when they move synchronously, they will not affect the normal operation of the entire equipment.
[0026] The fixing roller assembly also includes a second fixing roller 9 and a third fixing roller 10. The second fixing roller 9 is positioned above the first fixing roller 6, and the third fixing roller 10 is positioned above the wire collecting roller 4. The second fixing roller 9 and the third fixing roller 10 are used to control the winding direction of the metal wire 3. The wire collecting roller 4 is provided with a wire hook 11 for fixing the metal wire 3. The end of the metal wire is connected to a flexible wire 12, which is used to assist the metal wire 3 in passing through the hole to be cut. The upper part of the wire hook 11 is a flared opening 13, and the lower part of the wire hook 11 is a vertical slit 14. The flexible wire 12 first slides into the vertical slit 14 through the flared opening 13, and the vertical slit 14 holds the knot 15 of the flexible wire 12, thereby fixing the flexible wire 12.
[0027] Furthermore, this invention also solves the problem of threading wires when drilling holes in parts. Specific embodiments are as follows:
[0028] like Figures 3-6 As shown, a metal wire 3 cutting machine capable of cutting internal holes includes a motor, a control system, a wire collecting roller 4, and a fixed roller assembly. The metal wire 3 is sleeved on the outside of the wire collecting roller 4 and the fixed roller assembly. The fixed roller assembly includes a first fixed roller 6. The wire collecting roller 4 and the first fixed roller 6 form a cutting area. A first displacement roller 1 and a second displacement roller 2 are also provided in the cutting area. The first displacement roller 1 and the second displacement roller 2 move synchronously laterally. The first displacement roller 1 is positioned above the second displacement roller 2. The end of the metal wire 3 is connected to a flexible wire 12. The machine also includes a hook 17 and a clamping device 18. The hook 17 is used to lift the flexible wire 12 and pass it through the hole to be cut in the part 21. The clamping device 18 has an open state and a clamping state. The clamping device 18 can be a clamping arm, which is driven by a motor to clamp or open. The outer end of the flexible wire 12 is provided with a knot 15. The hook 16 of the hook 17 hooks the knot 15 to prevent the flexible wire 12 from detaching from the hook 17. The wire collecting roller 4 is equipped with a wire hook 11. The upper part of the wire hook 11 is a flared opening 13, and the lower part of the wire hook 11 is a vertical slit 14. The knot 15 cannot pass through the vertical slit 14, thus achieving a fixing effect. The hook 17 is elongated, and the hook part is located at the lower end of the hook 17.
[0029] A method for cutting internal holes with a metal wire cutter includes the following steps:
[0030] Step 1: Rotate the wire collecting roller 4, and the soft wire 12 at the end of the metal wire 3 at the second displacement roller 2 will disengage from the wire collecting roller 4;
[0031] Step 2: The clamping device 18 is in the clamping state, and the clamping device 18 fixes the free end of the flexible wire 12. The other end of the flexible wire 12 is wrapped around the outside of the second displacement gear. The wire collecting roller 4 is rotated so that both the metal wire 3 and the flexible wire 12 are in a taut state.
[0032] Step 3: Drill holes at the locations where the inner holes of part 21 need to be cut to form wire-threading holes to be cut;
[0033] Step 4: The hook 17 passes through the hole to be cut from top to bottom. The hook 17 is aligned with the soft wire 12 and the soft wire 12 is lifted upwards. The clamping device 18 is opened, and the soft wire 12 is released from the clamping device 18. The soft wire 12 passes through the hole to be cut along with the hook 17. The size of the hook part 16 of the hook 17 is smaller than the size of the knot 15 of the soft wire 12. The hook part 16 hooks the knot 15 and lifts the soft wire 12 upwards. The soft wire 12 will not be released from the hook part 16.
[0034] Step 5: Locate the free end of the flexible wire 12 and fix it to the wire collecting roller 4. As the wire collecting roller 4 rotates, the metal wire 3 enters the hole to be cut. The outer end of the flexible wire 12 is provided with a knot 15, and the wire collecting roller 4 is provided with a wire hook 11. The upper part of the wire hook 11 is a flared opening 13, and the lower part of the wire hook 11 is a vertical slit 14. The flexible wire 12 is fixed to the wire collecting roller 4 through the knot 15 and the wire hook 11, making it easier to fix the flexible wire 12.
[0035] Step 6: The hook 17 moves the soft line 12 above the wire collecting roller 4. The hook 17 moves down aligned with the wire hook 11. The soft line 12 enters the vertical gap 14, and the knot 15 of the soft line 12 is released from the hook 17. The soft line 12 is fixed by the wire hook 11.
[0036] Step 7: Rotate the wire collecting roller 4, and the metal wire 3 moves to cut the hole to be cut.
[0037] The present invention has provided a detailed description of a metal wire cutting machine with a single-wire roller.

The descriptions of these embodiments are merely for the purpose of helping to understand the invention and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
