Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting machine tools, in particular to a water spray plate used for wire cutting machine tools. Background Art

[0002] Wire cutting machine tool processing is a branch of electrospark machining. It is a process method that directly uses electric sparks for processing. It uses a moving wire (electrode wire) as a tool electrode to cut the workpiece, so it is called wire cutting processing. In wire cutting processing, the relative movement of the workpiece and the electrode wire is realized by digital control, so it is also called CNC electrospark wire cutting processing, or wire cutting processing for short.

[0003] In the online cutting processing assembly, working fluid needs to be continuously added to the cutting wire. The working fluid has good lubrication and cooling effects, and can effectively protect the cutting wire and increase its service life. The working fluid flows into the water spray plate through a pressurized pipe. The water spray plate is provided with a wire groove, and a water spray nozzle is provided in the wire groove. The cutting wire passes through the wire groove, and the working fluid is sprayed onto the wire through the water spray nozzle to achieve a protective effect.

[0004] The above-mentioned prior art solutions have the following defects: since the cutting wire is always in a reciprocating wire-feeding state during cutting, the cutting wire will experience high-speed tiny vibrations in the wire-feeding state, which will quickly throw off the working fluid attached to the surface of the cutting wire, causing the working fluid flow of the cutting wire to be unstable, greatly affecting the cutting effect of the workpiece. Utility Model Content

[0005] The utility model aims to provide a water spray plate for a wire cutting machine tool.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] It comprises a hollow water spray plate body, a wire groove is formed through the center of the water spray plate body, a through groove connected to the wire groove is formed on the side wall of the water spray plate body, a connecting nozzle is fixedly provided on the outer wall of the water spray plate, the connecting nozzle is externally connected to a pressurized pipe, cutting wires are formed through the wire groove at intervals, a plurality of water spray nozzles connected to the inside of the water spray plate body are evenly distributed on the groove wall of the wire groove, the water spray nozzles are aligned with the cutting wires, three groups of fixed brackets are extended from the outer wall of the water spray plate body, the fixed brackets are evenly distributed around the wire groove, a pressure roller is fixedly installed on the end of the fixed bracket, and the outer edge of the pressure roller is fixedly arranged to abut against the cutting wire.

[0008] By adopting the above technical scheme, when working, the working fluid is input into the water spray plate body from the pressurized pipe, and is ejected from the water spray nozzle to the reciprocating cutting wire. The pressure roller that resists the cutting wire has a good limiting effect, and resists and limits the cutting wire from three directions, and plays a role in suppressing vibration in the middle section of the cutting wire, thereby avoiding the shaking of the cutting wire and the unstable adhesion of the surface liquid flow on both sides under the action of vibration, which affects the cutting effect, and can improve the cutting quality of the workpiece.

[0009] Furthermore, the outer edge of the pressure roller is an elastic rubber wheel, and the rim of the pressure roller is concave.

[0010] By adopting the above technical solution, the concave elastic rubber wheel has good elasticity and insulation, ensuring that the pressure roller can adaptively deform to increase the contact area with the cutting wire and is not easy to slip, ensuring that the pressure roller can always stick to the surface of the cutting wire for pressing, and at the same time it can be suitable for cutting wires of different diameters and can be selected for use within the elastic variation range.

[0011] Furthermore, the fixed bracket includes a positioning bracket fixedly connected to the water spray plate body and a hinged bracket hinged to the water spray plate body, the outer edge of the positioning bracket away from the cutting wire is provided with a fixing ring for engagement and rotation, the positioning bracket and the hinged bracket are provided with an engagement opening for engagement and rotation of the fixing ring on the side away from the cutting wire, and the fixing ring is provided to resist and tighten the hinged bracket.

[0012] By adopting the above technical solution, the setting of the articulated bracket can be opened to release the clamping area between the three sets of pressure rollers, making it easier for the threaded cutting wire to cut in from the side and reach the central clamping area, and cooperate with the fixing ring to lock and tighten the articulated bracket to lock the clamping area to achieve a stable clamping effect.

[0013] Furthermore, the fixing ring is truncated with a through opening, an intercepting plate hinged to the fixing ring is fixedly provided at one end of the through opening, a first pin inserted into the other end of the fixing ring is penetrated at the end of the intercepting plate, and a second pin penetrating the fixing ring is inserted into the fixing bracket.

[0014] By adopting the above technical solution, the setting of the through opening is also convenient for the threaded cutting wire to cut into the central clamping area from the side. The through opening can be opened by pulling out the second pin and rotating the intercepting plate. The position of the through opening can be adjusted by pulling out the first pin and rotating the fixing ring, which makes it easy to release the lock of the articulated bracket and achieve the effect of adjusting the state of the articulated bracket. Conversely, all fixed brackets can be locked by rotating the fixing ring to the appropriate position. The fixing ring can be limited by inserting the first pin and the second pin to lock the device as a whole.

[0015] Furthermore, a pair of engaging ridges are fixedly provided on the outer edge of the end of the connection nozzle, the pressurized pipe is sleeved on the outer edge of the connection nozzle, and the pressurized pipe is bundled with a cable tie located between the engaging ridges.

[0016] By adopting the above technical solution, when the cable tie is tightened, it will compress the pressurized pipe so that part of it sinks into the gap between the convex edges, thereby achieving the effect of locking the connecting nozzle and the pressurized pipe, which facilitates the long-term stable spraying of the working fluid.

[0017] In summary, the beneficial technical effects of the utility model are:

[0018] 1. The fixed bracket and pressure roller are used to limit the cutting wire from three directions, which can suppress vibration in the middle of the cutting wire and improve the cutting quality of the workpiece;

[0019] 2. The concave elastic rubber wheel is used to produce adaptive deformation to increase the contact area with the cutting wire and is not easy to slip, so it is suitable for cutting wires of different diameters;

[0020] 3. A fixed bracket, an articulated bracket, a fixed ring, a through hole, an intercepting plate, a first latch and a second latch are adopted, thereby producing an effect of adjusting the state of the articulated bracket and the pressing roller according to actual needs.
