Description

Technical Field

[0001] This utility model relates to wire cutting equipment, and more particularly to a wire guide mechanism with a pneumatic lifting and chip suction 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 waste chips generated by the wire EDM machine tool fall into the waste chip box through the waste chip collection through-hole on the cutting platform, and the waste chips generated by the cutting are collected. However, the waste chip recovery structure of 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 possible 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. 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. Furthermore, the wire guiding mechanism of this type of wire EDM machine typically uses a motor and lead screw nut structure for lifting operations. This requires components such as a motor, coupling, drive belt, lead screw, and nut, occupying a large space. Limited by motor speed and lead screw lead, speed increases are limited, and there is an acceleration / deceleration process, resulting in a long response time. The motor and lead screw nut structure require regular maintenance, and the lead screw is susceptible to cutting fluid contamination, shortening the equipment's lifespan. 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 pneumatic lifting and chip suction structure.

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

[0005] A wire guide mechanism with pneumatic lifting and chip suction structure, comprising:

[0006] A support frame is installed in the cutting equipment and has a load-bearing space inside.

[0007] The transfer assembly frame is installed in the support frame via a vertical sliding structure and can rise or fall within the support frame.

[0008] The lifting drive cylinder is a rodless cylinder. Its cylinder body is installed in the support frame, and its slider is engaged with the transfer assembly frame. The lifting drive cylinder drives the transfer assembly frame to rise or fall.

[0009] The wire threading guide tube is installed in the transfer assembly frame and can rise or fall together with the transfer assembly frame. The wire threading guide tube guides the wire threading process of the cutting wire.

[0010] The waste collection end is installed in the support frame through a lifting structure. It can move together with the support frame and can rise or fall in the support frame to collect the cutting waste.

[0011] In one embodiment of this utility model, a cooling water nozzle is provided in the support frame, and the cooling water nozzle is positioned corresponding to the wire threading guide tube. When the wire threading guide tube descends, its bottom can pass through the cooling water nozzle, so that the wire threading guide tube and the cooling water nozzle are connected.

[0012] The support frame is equipped with a fixed clamping block and a movable clamping block. The fixed clamping block is installed at the bottom of the support frame through a fixed connector and is located on one side of the threading guide tube. The movable clamping block is installed in the support frame through a clamping cylinder and is located on the other side of the threading guide tube. The movable clamping block is moved by the clamping cylinder to clamp the threading guide tube between the fixed clamping block and the movable clamping block, thereby clamping and positioning the bottom of the threading guide tube.

[0013] In one embodiment of this utility model, a suction port is provided in the support frame, and the waste chip suction end passes through the suction port, which can move away from or close to the cutting waste chip when it rises or falls.

[0014] The waste chip collection end is made of electromagnet, which allows the waste chip collection end to attract and collect cutting waste through magnetic force. When the waste chip collection end descends, it is energized and magnetized, generating an attraction magnetic force that can attract cutting waste. When it rises, the power is turned off and the magnetism is deactivated, causing the attracted cutting waste to fall off. When the waste chip collection end rises, the collection port can also provide assistance in the process of removing cutting waste.

[0015] In one embodiment of this utility model, a suction drive frame is installed in the support frame, and the suction drive frame corresponds to the position of the waste collection end.

[0016] The suction drive frame is equipped with a suction drive cylinder. The piston rod of the suction drive cylinder is engaged with the waste collection end, and the suction drive cylinder drives the waste collection end to rise or fall.

[0017] In one embodiment of the present invention, the piston rod of the suction drive cylinder and the top of the waste collection end are connected to each other by an extension plate. The inner end of the extension plate extends into the suction drive frame and is connected to the end of the piston rod of the suction drive cylinder. Its outer end extends to the outside of the suction drive frame and is connected to the top of the waste collection end.

[0018] In one embodiment of this utility model, the waste collection end and collection port are cylindrical structures and arranged vertically, parallel to the direction of the cutting wire conveying in the wire guide tube.

[0019] In one embodiment of this utility model, a guide rail is provided on the side of the support frame. The guide rail is arranged vertically and is parallel to the lifting drive cylinder. The transfer assembly frame cooperates with the guide rail through a slider, and the guide rail guides the rising or falling process of the transfer assembly frame.

[0020] The advantages of this utility model are:

[0021] This wire guide mechanism replaces the traditional lifting structure composed of a motor and lead screw and nut pair with a rodless cylinder, which has the advantages of simplified structure and convenient installation, reduces manufacturing and assembly difficulty and cost, and improves installation efficiency. Its operation is stable and can provide stable lifting and lowering motion for the transfer assembly frame and the wire guide core tube. The waste chip collection end is installed in the support frame through the lifting structure and can move with the support frame. It can rise or fall in the support frame to attract and collect cutting waste chips. The wire guide mechanism uses a waste chip collection end made of electromagnet. When the waste chip collection end descends, it is energized to attract metal waste chips, and when it rises, it is de-energized to release them. Combined with the auxiliary detachment of the collection port, it realizes automated waste chip cleaning and reduces the impact of waste chip accumulation on cutting accuracy.
