Description

Technical Field

[0001] This utility model relates to the field of wire EDM machine tool technology, and specifically to a wire feeding device for a wire EDM machine tool. Background Technology

[0002] Wire EDM, short for CNC wire electrical discharge machining, works by using a moving metal wire as a tool electrode. A pulsed current is applied between the wire and the workpiece, and the workpiece is cut using the corrosive effect of the pulsed discharge. Because it uses a wire electrode, it can only perform contour cutting. Patent CN202122976744.5 discloses a wire feeding device for a wire EDM machine. A spring pushes a mounting block, which in turn moves an oil reservoir, causing the balls in the reservoir to come into contact with the wire for lubrication and rust prevention. However, when grinding the wire used in the wire EDM machine, rust particles on the wire surface are generated, accumulating in the mounting frame and potentially affecting its operation. Therefore, we propose a wire feeding device for a wire EDM machine. Utility Model Content

[0003] To address the problems in the prior art, this utility model provides a wire feeding device for a wire EDM machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is a wire feeding device for a wire EDM machine, including a ring shell. A support plate is bolted to the top surface of the ring shell, and a reducer is mounted at one end of the support plate inside the ring shell. A vertical shaft for transmission is mounted between the power output end of the reducer and the ring shell, and a grinding roller for wire grinding is sleeved on the outer circumference of the vertical shaft. A dual-axis motor that is connected to the reducer is mounted on the top surface of the support plate.

[0005] The top surface of the disc frame is fitted with a housing located on the outer periphery of the dual-axis motor, and the top surface of the housing is fitted with a perforated cover for support. The end of the dual-axis motor away from the disc frame is fitted with a cylinder seat for transmission, and the end of the perforated cover near the disc frame is rotatably mounted with a cross shaft that engages with the cylinder seat. The outer periphery of the cross shaft is fitted with a fan blade.

[0006] By adopting the above technical solution, during the use of wire cutting machine tools, the dual-axis motor on the surface of the disc can operate and drive the vertical shaft to rotate under the operation of the reducer. The vertical shaft can drive the grinding roller to rotate and cooperate with the internal structure of the ring shell to facilitate grinding and rust removal of the wire, making it convenient for maintenance. Moreover, the debris generated during grinding can slide along the inclined surface on the bottom side of the ring shell, making it convenient to discharge and reducing the accumulation of debris inside the ring shell.

[0007] When the dual-axis motor is running, it can drive the cylinder base to rotate, which in turn drives the cross shaft to rotate. This, in turn, drives the fan blades to rotate and facilitates airflow into the annular housing. This allows the grinding debris to slide and be guided more smoothly by the airflow, ensuring stable debris discharge. At the same time, the multi-hole cover on the top of the housing is easy to install and remove. Because the cross shaft and cylinder base are interlocked, disassembly is easy, and the fan blades can be easily disassembled and maintained, making it convenient for use.

[0008] Specifically, a ring seat for support is screwed onto the bottom surface of the ring shell, and a valve plate for protection is hinged inside the ring seat via a torsion spring hinge, and there are two sets of valve plates.

[0009] By adopting the above technical solution, the ring seat can easily support the valve plate. When the wind blows the debris in the ring shell, it will also blow open the valve plate in the ring seat, so that the valve plate will open automatically to facilitate the discharge of debris. When the wind stops, the valve plate can automatically close and seal the ring seat under the torsion spring hinge torque.

[0010] Specifically, a dust collection tray is screwed onto the end of the ring seat away from the ring shell, and a support washer is screwed onto the air outlet end of the tray. A filter screen is installed inside the washer, and a gauze layer is installed on the side of the filter screen located inside the tray.

[0011] By adopting the above technical solution, the debris passing through the ring seat can easily accumulate in the tray. At the same time, the gasket in the tray intercepts the debris through the filter plate and gauze layer, while air can easily pass through, which helps to reduce the situation of debris being discharged randomly.

[0012] Specifically, the outer peripheral surface of the tray is integrally constructed with protrusions, and there are multiple sets of protrusions.

[0013] By adopting the above technical solution, the protrusions make the pallet easier and more convenient to assemble and disassemble, and facilitate the cleaning of debris in the pallet.

[0014] Specifically, both the inner side of the tray frame and the inner side of the porous cover are equipped with a filter layer for protection.

[0015] By adopting the above technical solution, the filter layer can easily protect the disc frame and the porous cover, which can reduce the entry of external debris into the ring shell and enable the structure in the ring shell to operate more stably.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of the disc frame, reducer, vertical shaft, grinding roller and dual-axis motor, enables the dual-axis motor on the surface of the disc frame to operate and drive the vertical shaft to rotate under the operation of the reducer during the use of wire cutting machine. This allows the vertical shaft to drive the grinding roller to rotate and cooperate with the internal structure of the ring shell to facilitate grinding and rust removal of the wire, making it convenient for maintenance. Moreover, the debris generated during grinding can slide along the inclined surface on the bottom side of the ring shell, making it easy to discharge and reducing the accumulation of debris inside the ring shell.

[0018] 2. The technical solution of this application, through the design of the cylinder base, shell, perforated cover, cross shaft, and fan blade body, enables the cylinder base to rotate when the dual-axis motor is operating. Subsequently, the cylinder base can easily drive the cross shaft to rotate, which in turn drives the fan blade body to rotate, facilitating airflow into the annular shell. This allows the grinding debris to be more smoothly guided by the airflow, ensuring stable debris discharge. At the same time, the perforated cover on the top of the shell is easy to install and remove, and because the cross shaft and cylinder base are interlocked, disassembly is convenient, and the fan blade body can be easily disassembled and maintained, making it convenient for use.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3This utility model provides a technical solution: a wire feeding device for a wire EDM machine, including an annular shell 1. A support plate 2 is bolted to the top surface of the annular shell 1, and a reducer 3 is mounted at one end of the support plate 2 inside the annular shell 1. A vertical shaft 4 for transmission is mounted between the power output end of the reducer 3 and the annular shell 1, and a grinding roller 5 for wire grinding is sleeved on the outer periphery of the vertical shaft 4. A dual-axis motor 6 connected to the reducer 3 is mounted on the top surface of the support plate 2. A housing 8 located on the outer periphery of the dual-axis motor 6 is mounted on the top surface of the support plate 2, and a perforated cover 9 for support is mounted on the top surface of the housing 8. A cylinder seat 7 for transmission is mounted at the end of the dual-axis motor 6 away from the support plate 2, and a cross shaft 10 that engages with the cylinder seat 7 is rotatably mounted at the end of the perforated cover 9 near the support plate 2. A fan blade 11 is mounted on the outer periphery of the cross shaft 10.

[0026] During use, when the wire feeder is used on the wire cutting machine, the dual-axis motor 6 on the surface of the disc 2 can operate and drive the vertical shaft 4 to rotate under the operation of the reducer 3. The vertical shaft 4 can drive the grinding roller 5 to rotate and cooperate with the internal structure of the ring shell 1 to facilitate grinding and rust removal of the wire, making it convenient for maintenance. The debris generated during grinding can slide along the inclined surface on the bottom side of the ring shell 1, making it convenient to discharge and reducing the accumulation of debris inside the ring shell 1.

[0027] When the dual-axis motor 6 operates, it drives the cylinder base 7 to rotate. The cylinder base 7 then drives the cross shaft 10 to rotate, which in turn drives the fan blade body 11 to rotate, facilitating airflow into the annular shell 1. This allows the grinding debris to slide and be guided more smoothly by the airflow, ensuring stable debris discharge. At the same time, the perforated cover 9 on the top of the shell 8 is easy to install and remove. Since the cross shaft 10 and the cylinder base 7 are interlocked, disassembly is convenient, and the fan blade body 11 can be easily disassembled and maintained, making it convenient for use.

[0028] like Figure 1 and Figure 2 As shown, a ring seat 12 for support is screwed onto the bottom surface of the ring shell 1, and a valve plate 13 for protection is hinged inside the ring seat 12 by a torsion spring hinge, and there are two sets of valve plates 13.

[0029] In use, the ring seat 12 provides convenient support for the valve plate 13. When the wind blows the debris in the ring shell 1, it will also blow open the valve plate 13 in the ring seat 12, so that the valve plate 13 opens automatically to facilitate the discharge of debris. When the wind stops, the valve plate 13 can automatically close under the torsion spring hinge torque and seal the ring seat 12.

[0030] like Figure 1 and Figure 2As shown, a dust collection tray 14 is screwed onto the end of the ring seat 12 away from the ring shell 1, and a support washer 15 is screwed onto the air outlet end of the tray 14. A filter screen plate 16 is installed inside the washer 15, and a gauze layer 17 is installed on the side of the filter screen plate 16 located inside the tray 14.

[0031] During use, debris passing through the ring seat 12 can easily accumulate in the tray 14. At the same time, the gasket 15 in the tray 14 intercepts the debris through the filter plate 16 and the gauze layer 17, while air can easily pass through, which helps to reduce the situation of debris being discharged randomly.

[0032] like Figure 1 and Figure 2 As shown, the outer peripheral surface of the tray 14 has an integrally formed protrusion 18, and there are multiple sets of protrusion 18.

[0033] When in use, the protrusion 18 makes it easier and more convenient to disassemble and assemble the tray 14, and facilitates the cleaning of debris in the tray 14.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, both the inner side of the tray 2 and the inner side of the porous cover 9 are equipped with a filter layer 19 for protection.

[0035] When in use, the filter layer 19 provides convenient protection for the disc holder 2 and the porous cover 9, which helps to reduce the entry of external debris into the ring shell 1, allowing the structure in the ring shell 1 to operate more stably.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the wire cutting process, the dual-axis motor 6 on the surface of the disc frame 2 operates and, under the operation of the reducer 3, drives the vertical shaft 4 to rotate. This allows the vertical shaft 4 to drive the grinding roller 5 to rotate, cooperating with the internal structure of the ring shell 1 to facilitate grinding and rust removal of the wire, making maintenance easier. Furthermore, the debris generated during grinding can slide along the inclined surface on the bottom side of the ring shell 1, facilitating its discharge and reducing debris accumulation inside the ring shell 1. Simultaneously, when the dual-axis motor 6 operates, it drives the cylinder seat 7 to rotate. The cylinder seat 7 then drives the cross shaft 10 to rotate, which in turn drives the fan blade body 11 to rotate, facilitating airflow inside the ring shell 1, thus improving the grinding process. The debris can be smoothly guided by the wind, allowing for stable discharge. The perforated cover 9 on the top of the housing 8 is easy to install and remove. The cross shaft 10 and the cylinder seat 7 are interlocked, facilitating disassembly and maintenance of the fan blade 11. When the wind blows the debris in the ring housing 1, it also opens the valve plate 13 in the ring seat 12, allowing the debris to be discharged automatically. When the wind stops, the valve plate 13 automatically closes under the torsion spring hinge torque, sealing the ring seat 12. The debris passing through the ring seat 12 accumulates in the tray 14. The gasket 15 in the tray 14 intercepts the debris through the filter plate 16 and the gauze layer 17, while air can pass through, reducing the possibility of debris being discharged randomly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
