Description

Technical Field

[0001] This utility model relates to wire electrical discharge machining equipment, and more particularly to a wire guiding mechanism with a waste chip collection structure. Background Technology

[0002] Patent document CN214640797U discloses a wire EDM machine tool with recyclable waste chips, including a wire EDM machine tool body. A waste chip collection mechanism is provided on the outside of one end of the wire EDM machine tool body. A rectangular cutting platform is provided on the upper end of the waste chip collection mechanism. A rectangular through-hole for collecting waste chips is opened on the end of the cutting platform away from the wire EDM machine tool body. A waste chip collection box is provided at the lower end of the waste chip collection through-hole. The cutting machine tool is equipped with a waste chip box. The chips generated by the wire EDM machine tool fall into the waste chip collection box through the waste chip collection through-hole on the cutting platform and are collected. After the waste chips in the waste chip box are full, they are pressed into shape by metal powder pressing technology and can be reused as raw materials for parts, saving raw materials and reducing costs. At the same time, the waste chips do not accumulate on the cutting platform, so that the generated waste chips do not affect the cutting accuracy. However, the waste chip recovery structure used in this type of wire EDM machine consists of a waste chip collection box, relying solely on waste chip collection through-holes for collection. When waste chips are generated rapidly or unevenly distributed, it may not be able to effectively guide all waste chips through the through-holes into the collection box in a timely manner, resulting in some waste chips remaining on the cutting platform and affecting collection efficiency. Furthermore, the waste chip collection through-holes, as the only channel for waste chips to enter the collection box, are easily blocked by larger particles or clumps of waste chips. Once blocked, subsequent waste chips cannot fall into the collection box normally, causing waste chips to accumulate on the platform and disrupting the normal operation of the collection system. Therefore, it is necessary to optimize its structure to overcome these shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a wire guide mechanism with a waste chip collection structure, so as to absorb and collect the cutting waste chips from the wire EDM machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A wire guide mechanism with a waste collection structure, comprising:

[0006] The guide bracket is installed in the tapered mechanism of the cutting machine tool and can move together with the tapered mechanism. It has a cutting wire guiding space inside.

[0007] The suction end is installed in the guide frame through a lifting structure. It can move together with the guide frame and can rise or fall in the guide frame to absorb and collect cutting waste.

[0008] In one embodiment of this utility model, a suction port is provided in the guide frame, and the suction end passes through the suction port, so that it can move away from or close to the cutting waste when it rises or falls.

[0009] In one embodiment of this invention, the collecting end is made of an electromagnet, allowing it to magnetically attract and collect cutting waste. When the collecting end descends, it is energized to generate a magnetic force that attracts the cutting waste. When it rises, the power is turned off to demagnetize it, causing the cutting waste to fall off. The collecting port also assists in the process of the cutting waste falling off when the collecting end rises.

[0010] In one embodiment of this utility model, a cooling water nozzle is installed in the guide bracket. The cutting wire passes through the cooling water nozzle and cuts the workpiece. The suction port corresponds to the position of the cooling water nozzle, so that the suction end can move along the cutting path of the cutting wire.

[0011] In one embodiment of this utility model, the cutting wire guiding mechanism further includes:

[0012] A lifting frame is installed in a guide seat and corresponds to the position of the suction end;

[0013] A lifting cylinder is installed in the lifting frame, and its piston rod is engaged with the suction end. The lifting cylinder drives the suction end to rise or fall.

[0014] In one embodiment of the present invention, the piston rod of the lifting cylinder is connected to the top of the suction end through an extension plate. The inner end of the extension plate extends into the lifting frame and is connected to the end of the piston rod of the lifting cylinder. Its outer end extends to the outside of the lifting frame and is connected to the top of the suction end.

[0015] In one embodiment of this utility model, the suction end and suction port are cylindrical structures and are arranged vertically, parallel to the direction of the cutting wire conveying in the cooling water nozzle.

[0016] The advantages of this utility model are:

[0017] This wire guide mechanism uses an electromagnet-made suction end. When descending, it is energized to attract metal scraps, and when rising, it is de-energized to release them. Combined with the auxiliary detachment of the suction port, it achieves automated scrap cleaning, reducing the impact of scrap accumulation on cutting accuracy. The suction end can move with the guide frame, always keeping close to the cutting area to ensure immediate scrap adsorption. After being adsorbed, the scrap falls to a designated area, avoiding dust diffusion caused by traditional blowing methods, improving the working environment, and effectively solving the problem of fine metal scraps generated in the cutting of high-hardness materials, thus improving the surface quality of the processed material and the life of the equipment.

[0022] like Figures 1-3 As shown, the cutting wire guiding mechanism with a waste collection structure proposed in this utility model includes a guide frame 100 and a collection end 200. The wire frame is installed in the tapered mechanism of the cutting machine tool and can move together with the tapered mechanism. It has a cutting wire guiding space inside. The collection end is installed in the guide frame through a lifting structure and can move together with the guide frame. It can rise or fall in the guide frame and the cutting waste is adsorbed and collected by the collection end.

[0024] In this embodiment, the collecting end is made of an electromagnet, which allows the collecting end to attract and collect cutting waste through magnetic force. When the collecting end descends, it is energized and magnetized to generate an adsorption magnetic force that can attract cutting waste. When it rises, the power is turned off and the magnetism is deactivated, causing the cutting waste to fall off. When the collecting end rises, the collecting port can also assist in the process of the cutting waste falling off.

[0025] In this embodiment, a cooling water nozzle 120 is installed in the guide bracket. The cutting wire passes through the cooling water nozzle and cuts the workpiece. The suction port corresponds to the position of the cooling water nozzle, so that the suction end can move along the cutting path of the cutting wire.

The lifting frame is installed in the guide seat and corresponds to the position of the suction end. The lifting cylinder is installed in the lifting frame, and its piston rod is engaged with the suction end. The lifting cylinder drives the suction end to rise or fall.

[0027] In this embodiment, the piston rod of the lifting cylinder and the top of the suction end are connected to each other through the extension carrier plate 230. The inner end of the extension carrier plate extends into the lifting frame and is connected to the end of the piston rod of the lifting cylinder. Its outer end extends to the outside of the lifting frame and is connected to the top of the suction end.

[0028] In this embodiment, the suction end and suction port are cylindrical structures and are arranged vertically, parallel to the direction of the cutting wire conveying in the cooling water nozzle.
