Description

Technical Field

[0001] This utility model relates to the technical field of medium-speed wire EDM machine tools, specifically a medium-speed wire EDM machine tool with a winding mechanism. Background Technology

[0002] Medium-speed wire EDM machines belong to the category of reciprocating high-speed wire EDM machines. They reduce errors caused by material deformation and molybdenum wire wear through multiple cuts, resulting in machining quality between high-speed and low-speed wire EDM machines. The working principle of a medium-speed wire EDM machine is to use a continuously moving molybdenum wire (called the electrode wire) as the electrode to perform pulsed spark discharge on the workpiece to remove metal and cut it into shape. Because its wire feed speed and workpiece quality are between those of fast and slow wire EDM machines, it is called a medium-speed wire EDM machine.

[0003] Modern medium-speed wire EDM machines also feature a winding mechanism at the rear. This mechanism adjusts the wire tension to effectively prevent wire breakage due to excessive tension and poor cutting results due to insufficient tension. This design solves the problem of traditional medium-speed wire EDM machines' winding mechanisms being unable to adjust wire tension, thus improving the machine's reliability and machining quality.

[0004] However, the winding mechanism on existing medium-speed wire EDM machines is usually fixed in position, making it impossible to adjust the wire input position and resulting in insufficient overall flexibility.

[0005] Therefore, it is necessary to design a medium-speed wire EDM machine with a winding mechanism to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a medium-speed wire EDM machine tool with a winding mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A medium-speed wire EDM machine tool with a winding mechanism includes a fixed base. A machine tool base is fixedly installed on one side of the top of the fixed base. A cutting machine tool body is fixedly installed on the top side of one side of the machine tool base. A cutting device is fixedly installed on the side of the cutting machine tool body away from the machine tool base. A plurality of rotatable guide wheels are installed on the outer shell of the cutting machine tool body. A movable winding structure is fixedly installed on the other side of the top of the machine tool base. A wire input structure is also provided on the side of the winding structure away from the cutting machine tool body and fixedly installed on the top of the machine tool base.

[0009] The winding structure includes a motor mounting bracket and a bearing seat fixedly installed on the left and right sides of the top of the machine tool base. An adjusting motor is fixedly installed on one side of the motor mounting bracket. The output end of the adjusting motor is connected to a threaded rod. Limiting rods are also provided on the front and rear sides of the motor mounting bracket along the axial direction of the threaded rod. A movable plate is also connected to the threaded rod and the limiting rod. Stands are fixedly installed on the top left and right sides of the movable plate. A rotating winding roller is connected between the two stands. A winding motor is also connected to one side of the axial direction of the winding roller.

[0010] As a preferred embodiment of this utility model, the bottom front and rear sides of the movable plate are provided with limiting blocks that cooperate with the limiting rod, and the limiting blocks and the limiting rod are slidably connected. The middle position of the movable plate is provided with a threaded block that cooperates with the threaded rod, and the threaded block and the threaded rod are threadedly connected.

[0011] As a preferred embodiment of this utility model, the bottom front and rear sides of the movable plate are fixedly connected with sliders, and the top front and rear sides of the machine tool base are provided with sliding rails, and the sliders slide inside the sliding rails.

[0012] As a preferred embodiment of this utility model, one side of the threaded rod is keyed to the output end of the regulating motor, and the other side is rotatably connected through a bearing located on the bearing seat.

[0013] As a preferred embodiment of this utility model, the wire input structure includes a vertical fixing rod fixedly installed on the top of the machine tool base, a horizontal connecting rod fixedly connected to the vertical fixing rod by a fixing nut, and a plurality of rotatable output wheels installed on the horizontal connecting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, a medium-speed wire EDM machine tool with a winding mechanism is provided. The wire is fed into the winding roller on the winding structure by the wire input structure. The position of the winding roller can be adjusted laterally by the lateral adjustment mechanism below to change and adapt to the input position of the wire, making the entire winding mechanism more flexible. This flexibility allows the machine tool to adapt to workpieces of different shapes and sizes, thereby improving processing efficiency and adaptability. Moreover, through the lateral movement structure, the winding mechanism can more easily adjust the position of the wire, thereby optimizing the cutting path. This not only reduces cutting time but also reduces material waste and improves overall processing efficiency. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0025] A medium-speed wire EDM machine tool with a winding mechanism includes a fixed base 1, a machine tool base 2 fixedly mounted on one side of the top of the fixed base 1, a cutting machine tool body 3 fixedly mounted on one side of the top of the machine tool base 2, a cutting device 4 fixedly mounted on the side of the cutting machine tool body 3 away from the machine tool base 2, a plurality of rotatable guide wheels 5 mounted on the outer shell of the cutting machine tool body 3, a movable winding structure 6 fixedly mounted on the other side of the top of the machine tool base 2, and a wire input structure 7 fixedly mounted on the top of the machine tool base 2 on the side of the winding structure 6 away from the cutting machine tool body 3.

[0026] Specifically, the winding structure 6 includes a motor mounting bracket 61 and a bearing seat 62 fixedly installed on the left and right sides of the top of the machine tool base 2. An adjusting motor 63 is fixedly installed on one side of the motor mounting bracket 61, and a threaded rod 64 is connected to the output end of the adjusting motor 63. Limiting rods 65 are also provided on the front and rear sides of the motor mounting bracket 61 along the axial direction of the threaded rod 64. A moving plate 66 is also connected to the threaded rod 64 and the limiting rod 65. Stands 67 are fixedly installed on the left and right sides of the top of the moving plate 66, and a rotating winding roller 68 is connected between the two stands 67. A winding motor 69 is also connected to one side of the axial direction of the winding roller 68. Limiting blocks that cooperate with the limiting rods 65 are provided on the front and rear sides of the bottom of the moving plate 66, and the limiting blocks and the limiting rods 65 are slidably connected. A threaded block that cooperates with the threaded rod 64 is provided in the middle of the moving plate 66, and the threaded block and the threaded rod 64 are threadedly connected. A slider 66 is fixedly connected on the front and rear sides of the bottom of the moving plate 66. 1. The top front and rear sides of the machine tool base 2 are provided with sliding rails 662, and the slider 661 slides inside the sliding rails 662; one side of the threaded rod 64 is keyed to the output end of the adjusting motor 63, and the other side is rotatably connected through the bearing 621 located on the bearing seat 62; the output end of the adjusting motor 63 drives the threaded rod 64 to rotate, which in turn drives the moving plate 66 to move laterally under the restriction of the limit rod 65, thereby changing the position of the upper winding roller 68 and the winding motor 69 to change and adapt the input position of the wire, making the entire winding mechanism more flexible. This flexibility allows the machine tool to adapt to workpieces of different shapes and sizes, thereby improving processing efficiency and adaptability. Moreover, through the lateral movement structure, the winding mechanism can more easily adjust the position of the wire, thereby optimizing the cutting path. This not only reduces cutting time but also reduces material waste and improves overall processing efficiency.

[0027] Specifically, the wire input structure 7 includes a vertical fixing rod 71 fixedly installed on the top of the machine tool base 2. A horizontal connecting rod 73 is fixedly connected to the vertical fixing rod 71 by a fixing nut 72. Multiple rotatable output wheels 74 are installed on the horizontal connecting rod 73. By setting multiple output wheels 74 and matching them with the adjustable winding structure 6, the wire input is facilitated.

[0028] The working process of this utility model is as follows: When using a medium-speed wire EDM machine tool with a winding mechanism, the output end of the motor 63 is adjusted to drive the threaded rod 64 to rotate. This rotation, in turn, causes the moving plate 66 to move laterally under the constraint of the limit rod 65. This changes the position of the upper winding roller 68 and the winding motor 69, thereby altering and adapting the wire input position. This makes the entire winding mechanism more flexible, allowing the machine tool to adapt to workpieces of different shapes and sizes, thus improving processing efficiency and adaptability. The wire is guided through the winding structure 6 and then through multiple guide wheels 5 to the cutting device 4. This allows the winding mechanism to more easily adjust the wire position, optimizing the cutting path. This not only reduces cutting time but also minimizes material waste and improves overall processing efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
