Description

Technical Field

[0001] This invention relates to the field of cutting machines, and more particularly to a metal wire cutting machine with dual wire-collecting rollers. Background Technology

[0002] A wire EDM machine is a device used for the precise cutting of sheet metal materials, and is 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 wheel, cutting wire, rollers, and a control system.

[0003] Traditional wire EDM machines use a thin wire as the cutting tool, cutting the material through high-speed pulsed discharge during wire drawing. The cutting wire is typically made of molybdenum alloy, which has high conductivity. During the cutting process, the wire is taut with rollers as support points. The upper and lower rollers are perpendicular and close to the metal material to be processed, performing pulsed discharge for cutting. However, traditional wire EDM machines have some drawbacks.

[0004] 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.

[0005] 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 design structure with independent movement of the upper and lower rollers, enabling flexible adjustment of the cutting equipment and adapting to the cutting needs of large parts.

[0006] Metal wire cutting machines are divided into single wire-collecting rollers and double wire-collecting rollers. This invention is aimed at metal wire cutting machines with double wire-collecting rollers. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a metal wire cutting machine with double wire rollers. During cutting, the metal wire in the cutting area is moved by moving two displacement rollers. No equipment is required, and the cutting position can be flexibly adjusted to meet the cutting needs of large parts.

[0008] The technical solution adopted by this invention to solve the above-mentioned technical problems is a metal wire cutting machine with double wire-collecting rollers, including a motor, a control system, and a wire-collecting roller assembly. A metal wire is sleeved on the outside of the wire-collecting roller assembly. The wire-collecting roller assembly includes a first wire-collecting roller and a second wire-collecting roller, forming a cutting area between them. A first displacement roller and a second 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 first wire-collecting roller are connected by a first metal wire, which is positioned above both the first displacement roller and the first wire-collecting roller. The second displacement roller and the second wire-collecting roller are connected by a second metal wire, which is positioned below both the second displacement roller and the second wire-collecting roller. 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 displacement roller and the second displacement roller. The first metal wire, the second metal wire, and the third metal wire form a Z-shaped metal wire.

[0009] A further preferred embodiment of the present invention is that the upper ends of the first displacement roller and the first wire collecting roller are at the same height, so that the first metal wire is in the horizontal direction.

[0010] A further preferred embodiment of the present invention is that the lower ends of the second displacement roller and the second wire collecting roller are at the same height, so that the second metal wire is in the horizontal direction.

[0011] 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.

[0012] A further preferred embodiment of the present invention is that both the first wire collecting roller and the second wire collecting roller are provided with wire hooks for fixing the metal wires.

[0013] 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.

[0014] 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 between a first fixed roller and the second displacement roller, and a third metal wire between the first and second displacement rollers. These three metal wires combine to form a Z-shaped metal wire 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. After the third metal wire moves, it can cut the part without moving the part itself, making the cutting more flexible, especially suitable for cutting large parts. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] 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, traditional wire cutting machines can only change position by moving the parts themselves, and cannot adjust the cutting position by moving the fixed rollers.

[0023] like Figure 2 , Figure 5 , Figure 6 As 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. This invention mainly introduces a technical solution applied to a double wire-collecting roller.

[0024] A wire cutting machine suitable for dual wire-collecting rollers 4. A wire cutting machine with dual wire-collecting rollers 4 includes a motor, a control system, and a wire-collecting roller 4 assembly. The motor drives the wire-collecting rollers 4 to rotate, and the control system controls the rotation speed and direction of the motor. A metal wire 3 is sleeved on the outside of the wire-collecting roller 4 assembly. The wire-collecting roller 4 assembly includes a first wire-collecting roller 41 and a second wire-collecting roller 42. The metal wire 3 can move from the first wire-collecting roller 41 to the second wire-collecting roller 42, or vice versa. A cutting area is formed between the first wire-collecting roller 41 and the second wire-collecting roller 42. A first displacement roller 1 and a second displacement roller 2 are also provided within the cutting area, and the first displacement roller 1 and the second displacement roller 2 move back and forth laterally 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 first wire collecting roller 41 are connected by a first metal wire 5, which is positioned above both the first displacement roller 1 and the first wire collecting roller 41. The second displacement roller 2 and the second wire collecting roller 42 are connected by a second metal wire 7, which is positioned below both the second displacement roller 2 and the second wire collecting roller 42. 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 first metal wire 5, the second metal wire 7, and the third metal wire 8 form a Z-shaped metal wire 3. The movement of the first displacement roller 1 and the second displacement roller 2 does not cause any changes in the overall shape of the metal wire 3, and the first displacement roller 1 and the second displacement roller 2 do not affect the rotation of the wire collecting roller 4 assembly. The upper ends of the first displacement roller 1 and the first wire-collecting roller 41 are at the same height, making the first metal wire 5 horizontal. The lower ends of the second displacement roller 2 and the second wire-collecting roller 42 are at the same height, making the second metal wire 7 horizontal. The opposite sides of the first displacement roller 1 and the second displacement roller 2 are on the same vertical plane, making the third metal wire 8 vertical, and the vertical metal wire 3 is easier to cut. Both the first wire-collecting roller 41 and the second wire-collecting roller 42 are provided with wire hooks 11 for fixing the metal wire 3. 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 vertical slit 14 holds the knot 15 of the soft wire 12, thereby fixing the soft wire 12.

[0025] Furthermore, this invention also solves the problem of threading wires when drilling holes in parts. Specific embodiments are as follows:

[0026] like Figures 3-6As 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. 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.

[0027] A method for cutting internal holes with a metal wire cutter includes the following steps:

[0028] 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;

[0029] 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.

[0030] 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;

[0031] 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.

[0032] 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.

[0033] 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.

[0034] Step 7: Rotate the wire collecting roller 4, and the metal wire 3 moves to cut the hole to be cut.
