Description

Technical Field

[0001] This utility model relates to the field of wire cutting technology, and more specifically, to a wire cutting guide structure. Background Technology

[0002] Wire EDM (Electrical Discharge Machining) processes parts using the principle of electrical discharge. The workpiece is connected to the positive terminal of a pulse power supply, and a molybdenum or copper wire is used as the cutting wire. The wire is connected to the negative terminal of a high-frequency pulse power supply as the tool electrode, and the workpiece is cut using spark discharge.

[0003] Some existing wire EDM devices lack tension adjustment components between their guide structures, which can lead to wire slack or even wire skipping during prolonged operation, affecting subsequent product cutting. Therefore, we propose a new wire EDM guide structure. Utility Model Content

[0004] To solve the above problems, this utility model provides a wire cutting guide structure, which adopts the following technical solution:

[0005] A wire cutting guide structure includes a housing. Two symmetrically distributed support plates are fixedly installed on one side of the housing. Guide posts are fixedly installed on opposite sides of the two support plates. Mounting frames are fixedly installed on opposite sides of the two support plates. Support wheels are rotatably installed in both mounting frames. Stabilizing components are provided on the inner walls of opposite sides of the two mounting frames. A first support rod is rotatably installed inside the housing. A drive wheel is fixedly sleeved on the side wall of the first support rod. A second support rod is fixedly installed inside the housing. A first guide wheel is rotatably installed on the side wall of the second support rod. Two symmetrically distributed third support rods are fixedly installed on the inner wall of the housing. Second guide wheels are rotatably sleeved on the side walls of both third support rods. The first guide wheel is located below the second guide wheel. A metal wire is provided between the drive wheel, the first guide wheel, the support wheel, and the second guide wheel. Through holes matching the metal wire are opened in the two guide posts. A drive component is provided on the side wall of the first support rod. A tension adjustment component is provided on the inner wall of the top of the housing.

[0006] By adopting the above technical solution, when the equipment is in use, the first support rod is driven to rotate by the drive component, and the first support rod drives the drive wheel to rotate, thereby causing the metal wire to be conveyed along the side walls of the drive wheel, the first guide wheel, the support wheel, the guide column, and the second guide wheel. This facilitates the subsequent cutting of products by the equipment. A tension adjustment component is provided between the metal wire and the inner wall of the top of the box. The tension adjustment component can adjust the tension of the metal wire during conveying, which helps to maintain the tightness of the metal wire during conveying, thereby reducing the phenomenon of wire jumping during the conveying of the metal wire and maintaining the stability of the metal wire during conveying. The support wheel can support and guide the metal wire, and there are stabilizing components in both mounting frames, which can press and restrict the metal wire, helping to prevent wire jumping during the operation of the equipment.

[0007] Furthermore, the stabilizing component includes connecting columns fixedly installed on the inner walls of opposite sides of the two mounting frames, with mounting plates fixedly installed at opposite ends of the two connecting columns, and multiple ball bearings arranged in a linear array rotatably installed on opposite sides of the two mounting plates.

[0008] By adopting the above technical solution, when the metal wire is conveyed on the side wall of the drive wheel, the first guide wheel, the support wheel, the guide column, and the second guide wheel, the mounting plate set in the mounting frame is located on the side wall of the support wheel on the same side, and the inner side of the mounting plate is provided with balls. The balls contact the side wall of the metal wire, which can press and restrict the metal wire, thus helping to avoid the phenomenon of wire jumping when the equipment is running.

[0009] Furthermore, the drive assembly includes a driven gear fixedly sleeved on the side wall of the first support rod, a geared motor fixedly installed on the inner wall of one side of the housing, and a drive gear fixedly sleeved on the side wall of the output shaft of the geared motor, wherein the drive gear and the driven gear mesh.

[0010] By adopting the above technical solution, the drive gear is driven to rotate by the geared motor, the drive gear drives the driven gear to rotate, the driven gear drives the first support rod to rotate, and the first support rod drives the drive wheel to rotate. The friction force generated between the drive wheel and the metal wire can drive the metal wire to move.

[0011] Furthermore, the tension adjustment assembly includes a telescopic rod fixedly installed on the inner wall of the top of the box, a support column fixedly installed at the end of the telescopic rod, a movable groove opened at the bottom of the support column, a support rod slidably installed in the movable groove, a spring fixedly connected between the top of the support rod and the inner wall of the top of the movable groove, a frame fixedly installed at the bottom of the support rod, and an adjustment wheel rotatably installed in the frame.

[0012] By adopting the above technical solution, the telescopic rod drives the support column, support rod, frame, and adjusting wheel to descend synchronously, so that the adjusting wheel contacts the metal wire. Then, under the driving force of the telescopic rod, the adjusting wheel pushes the metal wire downward. Through the cooperation of the two second guide wheels and the adjusting wheel, the tension of the metal wire during conveying is adjusted, which helps to maintain the tension of the metal wire during conveying, thereby reducing the phenomenon of wire skipping and maintaining the stability of the metal wire during conveying. When the adjusting wheel contacts the metal wire, the frame pushes the support rod to slide into the movable groove, and the support rod pushes the spring to contract. The spring gives the support rod a rebound force, which can play a buffering role.

[0013] Furthermore, two symmetrically distributed limiting blocks are fixedly installed on the top side wall of the support rod, and the inner wall of the movable groove is provided with a limiting groove that matches the limiting blocks.

[0014] By adopting the above technical solution, when the support rod slides in the movable groove, the support rod, along with the limiting block, slides in the limiting groove on the same side. The cooperation between the limiting block and the limiting groove helps to prevent the support rod from leaving the movable groove and helps to maintain the stability of the support rod sliding.

[0015] Furthermore, a pressing rod is rotatably mounted inside the housing, and the pressing rod is located above the drive wheel.

[0016] By adopting the above technical solution, the pressing rod above the drive wheel can limit the pressing of the metal wire, which helps to prevent the wire from jumping when the drive wheel drives the metal wire to move.

[0017] Furthermore, two symmetrically distributed stabilizing tubes are provided between the opposite ends of the two guide posts, and three connecting rods arranged in a ring array are fixedly installed between the two stabilizing tubes and the guide posts on the same side.

[0018] By adopting the above technical solution, the two guide columns are connected by a stabilizing tube and a connecting rod. The two stabilizing tubes are sleeved on the side wall of the metal wire, which can stabilize the metal wire and help maintain the stability of the metal wire's movement.

[0019] In summary, this utility model has the following beneficial technical effects:

[0020] (1) In this utility model, by setting the tension adjustment component, the tension of the metal wire is adjusted during the conveying process, which helps to keep the metal wire in a taut state during operation, thereby reducing the phenomenon of wire skipping and maintaining the performance of the equipment.
