Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire cutting technology, specifically a flat-push type clamping component. Background Technology
[0002] In the field of wire cutting, the electrode wire is the key medium for cutting metal materials. The stability and accuracy of its wire storage and take-up process directly determine the cutting quality and processing efficiency. In the wire storage and take-up system, the clamping component undertakes the functions of fixing, transmitting and adjusting the tension of the electrode wire, and is the core component to ensure the uniform and stable operation of the electrode wire.
[0003] Existing wire EDM wire storage mechanisms generally have certain limitations. Traditional wire take-up structures mostly use fastening structures on the take-up spool to resist and fix the wire to be taken up. However, during the process of resisting and fixing, it is easy to cause interference and creases to the wire, which can lead to wire breakage during repeated fixing and reduce the service life of the cutting wire. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a flat-push clamping assembly, which solves the limitations of existing wire EDM wire storage mechanisms. Traditional wire take-up structures mostly use fastening structures on the take-up drum to resist and fix the wire to be taken up. However, during the process of resisting and fixing, it is easy to cause interference and creases to the wire, which in turn causes the wire to break during repeated fixing, reducing the service life of the cutting wire.
[0005] This utility model provides the following technical solution: a flat-push type clamping assembly, including a wire storage cylinder, a cutting wire is provided on the bottom side of the wire storage cylinder, and a fixing seat is fixed on the side of the bottom end of the wire storage cylinder;
[0006] A guide rod is provided on the fixed base, and a guide sleeve is fitted on the guide rod. A movable device is provided on the side of the fixed base, and the movable device is fixedly connected to the guide sleeve. A return spring is fitted on the guide rod, one end of the return spring is connected to the guide sleeve, and the other end of the return spring is connected to the guide rod. A cylinder body is provided on the side of the movable device, and a cylinder bracket is fixed to the end of the cylinder body.
[0007] Preferred technical solution 1: A guide tube is provided on the side of the bottom end of the wire storage cylinder, and the cutting wire passes through the guide tube.
[0008] Preferred technical solution 2: The side of the fixing seat is arc-shaped.
[0009] Preferred technical solution three: The actuator consists of a limiting connecting block and an arc plate.
[0010] This solution enables the actuator to be better fixed and connected to the guide sleeve, and to prevent contact and friction between the cutting wire and the wire storage cylinder.
[0011] Preferred technical solution four: The cylinder body and the actuator are located on the same vertical plane.
[0012] This design enables the cylinder body's extension rod to push against the end of the actuator.
[0013] Preferred technical solution five: The end of the guide tube is inclined, and the end of the actuator extends to the bottom side of the end of the guide tube.
[0014] This design allows the cutting wire, which passes through the guide tube, to extend to the inner wall of the actuator.
[0015] Compared with the prior art, the present invention provides a flat-push type clamping assembly, which has the following advantages:
[0016] (1) This utility model has a fixed seat at the bottom of the wire storage tube and a movable device on the side of the fixed seat. The movable device can be pushed by the cylinder body to make the end of the cutting wire that passes through the guide tube fit against the wall of the wire storage tube to complete the fixing of the cutting wire. It will not cause excessive contact with the cutting wire, effectively ensuring that the cutting wire is safer during repeated fixing and will not interfere or crease, thereby improving its service life.

[0022] Please see Figure 1-4 ,
[0023] Example 1: A flat-push type clamping assembly includes a wire storage cylinder 1, a cutting wire 2 is provided on the bottom side of the wire storage cylinder 1, and a fixing seat 3 is fixed on the side of the bottom end of the wire storage cylinder 1.
[0024] A guide rod 4 is provided on the fixed base 3, and a guide sleeve 5 is fitted on the guide rod 4. A movable device 6 is provided on the side of the fixed base 3, and the movable device 6 is fixedly connected to the guide sleeve 5. A return spring 7 is fitted on the guide rod 4, one end of the return spring 7 is connected to the guide sleeve 5, and the other end of the return spring 7 is connected to the guide rod 4. A cylinder body 8 is provided on the side of the movable device 6, and a cylinder bracket 9 is fixed to the end of the cylinder body 8. A guide tube 10 is provided on the side of the bottom end of the wire storage cylinder 1, and the cutting wire 2 passes through the guide tube 10.
[0025] The side of the mounting base 3 is arc-shaped.
[0026] Example 2: The difference between this example and Example 1 is that the actuator 6 is composed of a limiting connecting block and an arc plate.
[0027] This allows the actuator 6 to be better fixed and connected to the guide sleeve 5, and to better fit and resist the cutting wire 2 and the wire storage cylinder 1.
[0028] Example 3: The difference between this example and Example 1 is that the cylinder body 8 and the actuator 6 are located on the same vertical plane.
[0029] This allows the extension rod of the cylinder body 8 to push against the end of the actuator 6.
[0030] Example 4: The difference between this example and Example 1 is that the end of the guide tube 10 is inclined, and the end of the actuator 6 extends to the bottom side of the end of the guide tube 10.
[0031] This allows the cutting wire 2, which passes through the guide tube 10, to extend to the inner wall of the actuator 6.
[0032] In this embodiment, existing wire EDM wire storage mechanisms generally have certain limitations. Traditional wire take-up structures mostly use fastening structures on the take-up drum to resist and fix the wire to be taken up. However, during the process of resisting and fixing, it is easy to cause certain interference and creases to the wire, which in turn causes the wire to break during repeated fixing, reducing the service life of the cutting wire.
[0033] In summary, in specific implementation, the cylinder bracket 9 at the end of the cylinder body 8 needs to be installed on the fixed frame limiting the wire storage drum 1, and the cylinder body 8 and the actuator 6 are located on the same vertical plane, so that the driving end of the cylinder body 8 can abut against the actuator 6. When the user needs to fix the cutting wire 2 and the wire storage drum 1.
[0034] At this time, the user first starts the cylinder body 8. When the cylinder body 8 rod extends, the actuator 6 moves parallel to the guide rod 4 on the fixed seat 3 and moves away from the contact point with the wire storage cylinder 1. At this time, the cutting wire 2 moves to the point where the actuator 6 and the wire storage cylinder 1 are separated through the guide tube 10. Then the cylinder body 8 rod retracts, and the actuator 6 returns to its original position along the guide rod 4 due to the action of the return spring 7. At this time, the actuator 6 and the wire storage cylinder 1 are tightly attached, and the cutting wire 2 is tightened to complete the fixation.
[0035] This mechanism can be used without pneumatic action. During operation, you can press the corresponding position of the actuator 6 at any angle on the wire storage cylinder 1 to easily move the fitting area open, and then put the cutting wire 2 into the exit position to tighten and complete the fixation.
[0036] The actuator 6 and the fixed base 3 move in a simple parallel manner, and the arc design allows it to fit tightly against the wire storage cylinder 1, ensuring that the tightened and fixed cutting wire 2 will not wear or deform, thus enabling repeated and effective use.
