Description

Technical Field

[0001] This utility model relates to the field of cutting machines, especially wire cutting machines, and particularly to an oil spraying device for wire cutting machines. Background Technology

[0002] In wire cutting operations, different cutting fluids are typically used depending on the material properties of the workpiece. For example, in silicon wafer cutting, pure water is usually used as the cutting fluid. Water has a high specific heat capacity; during the spraying process, the water absorbs the heat generated during wire cutting and carries it away through evaporation and heat conduction, thus achieving cooling. When cutting metal parts, because metal materials generally have good toughness and strength, better lubrication is needed to reduce friction between the cutting wire and the metal, lower cutting resistance, improve cutting efficiency, and extend the lifespan of the cutting wire. Therefore, oil-based cutting fluids are usually chosen. Oil-based coolants have good lubricity, a relatively gentle and long-lasting cooling effect, and can form an oil film in the cutting area, effectively reducing friction and wear. In some cases where high precision is required in metal processing, the lubricating properties of oil help reduce vibration and deviation during the cutting process. Oil-based coolants have good lubricity and adhesion, and can form a stable oil film on the machined surface, continuously absorbing and carrying away heat, making them suitable for long-term, continuous processing.

[0003] Currently, existing wire cutting machines using oil as the cutting fluid typically have an oil inlet pipe and an oil spray tank. The oil-based cutting fluid enters from one side of the spray tank through the inlet pipe and exits through a long groove on the other side, forming an oil curtain under the combined action of pressure and gravity. However, this structure results in uneven pressure distribution during the oil's entry and exit, and as it sprays into the long groove. Typically, the pressure is too high at the spray pipe location, while the pressure on both sides is too low. This can negatively impact the quality of cutting precision metal workpieces. Excessive flow and pressure can lead to excessively large kerfs, while insufficient flow and pressure can result in poor workpiece cooling efficiency, overheating causing cracking, or the metal wire being prone to breakage.

[0004] Therefore, it is necessary to further improve the structure of the existing oil injection device to make the oil curtain sprayed more uniform, stable and reliable. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides an oil spraying device for wire cutting machines, which can effectively improve the uniformity of the oil curtain, stabilize the oil curtain pressure, and provide a more uniform, smooth and stable lubrication effect for wire cutting.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an oil spraying device for a wire cutting machine, including an oil spraying groove, an oil inlet pipe and a T-shaped oil outlet pipe; the oil spraying groove has an inlet on one side and a main liquid outlet groove on the other side; the oil inlet pipe has an inlet end connected to an external oil supply mechanism for oil supply, and an outlet end connected to the oil spraying groove through the inlet; the T-shaped oil outlet pipe includes a vertical part and a horizontal part connected to the vertical part, the outer end of the vertical part is connected to the outlet end of the oil inlet pipe, and end liquid outlet grooves are respectively opened on the two end faces of the horizontal part, and at least two side wall long grooves are opened on each side of the outer circumferential wall of the horizontal part corresponding to the connection with the vertical part along the axial direction of the horizontal part.

[0007] In the above solution, to address the problem of uneven oil output caused by the original direct oil supply through the oil inlet pipe, a T-shaped oil outlet pipe is designed at the outlet end of the oil inlet pipe. This transforms the original single direct impact oil injection groove oil output line into a linear oil output line using the long groove on the side wall of the transverse section. At the same time, the oil is discharged from the end outlet grooves at both ends of the transverse section to supplement the oil pressure at both ends, so that the oil can flow out evenly from the main outlet groove, forming a uniform oil curtain, which is beneficial to improving the processing quality of the wire cutting machine.

[0008] Specifically, the T-shaped oil outlet pipe includes an internal tee connector and two side oil outlet pipes. The internal tee connector is T-shaped, with both ends connected to the side oil outlet pipes and the remaining end connected to the inlet pipe. Each side oil outlet pipe has an end discharge groove on its outer face and two long side wall grooves on its circumferential outer wall, which are parallel to the discharge grooves of the injection tank. The combination of the internal tee connector and the side oil outlet pipes effectively forms the T-shaped structure and facilitates the combined installation of the inlet and side oil outlet pipes.

[0009] Preferably, two long grooves are formed on the outer end face of the side oil delivery pipe on each side, and the two long grooves on the side walls of the same side oil delivery pipe are symmetrically arranged with respect to the axis of the side oil delivery pipe. That is, when the side oil delivery pipe has long grooves, oil can be discharged from both long grooves at the same time, avoiding excessive impact on the oil injection channel caused by oil discharge from one side, which would result in uneven liquid discharge.

[0010] Furthermore, the oil injection tank has a lower base plate and an upper inclined plate at the position corresponding to the liquid outlet tank. The upper inclined plate is above the lower base plate, and there is a gap between the lower edge of the upper inclined plate and the upper end face of the lower base plate. This gap is the channel for the oil to flow out.

[0011] Furthermore, the lower base plate extends outward from the projection position of the lower edge of the upper inclined plate onto the lower base plate, forming a flow plate. The outer end of the flow plate bends downward to form a lower guide plate, and the angle between the flow plate and the lower guide plate is an obtuse angle. The flow plate supports the oil flowing out from the gap, making the oil flow more stable and smooth, before it extends along the lower guide plate to form an oil curtain.

[0012] Furthermore, the upper inclined plate can be adjusted with an adjusting plate, which includes an adjustable inclined plate and an adjustable flat plate. The adjustable inclined plate is adjustablely disposed on the outer surface of the upper inclined plate and is parallel to the upper inclined plate. The adjustable flat plate is fixed to the lower edge of the adjustable inclined plate and is parallel to the flow plate. The gap between the flow plate and the adjustable flat plate forms a main outlet channel for oil flow. By adjusting the position of the adjusting plate, the gap height between the flow plate and the adjustable flat plate can be adjusted, thus adjusting the outlet height of the main outlet channel.

[0013] Preferably, the adjustable positioning of the adjustable inclined plate is formed by the cooperation of waist holes and bolts. The adjustable inclined plate has several waist holes, and bolts are installed in the waist holes to position and fix the adjustable inclined plate to the upper inclined plate. The length direction of the projection of the waist holes on the lower base plate is the direction of oil flow.

[0014] The beneficial effects of this utility model are that the oil spraying device for wire cutting machines provided by this utility model has a reasonable structural design. It features a T-shaped double-headed outlet design at the oil inlet pipe outlet position. The pipe fittings at both ends of the T-shaped outlet are respectively designed with side wall long grooves and end liquid outlet grooves, so that the oil flows out smoothly from the long grooves on both sides. The oil is also replenished at both ends through the end liquid outlet grooves, which avoids the end pressure being too low and further evens out the uniformity and stability of the liquid outlet grooves, which is conducive to stabilizing and improving the cutting quality.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0024] Example 1:

[0025] like Figures 1 to 4 The oil spraying device shown is an embodiment of this utility model for a wire cutting machine. The oil spraying device includes an oil spraying groove 6, an oil inlet pipe 1, and a T-shaped oil outlet pipe.

[0026] like Figure 2 and Figure 3 As shown, the fuel injection tank 6 is a hopper-shaped metal part with an internal chamber and a top cover. The fuel injection tank 6 has an inlet on one side and a main outlet tank on the other. The inlet end of the fuel inlet pipe 1 is connected to an external fuel delivery mechanism, which supplies fuel. The outlet end of the fuel inlet pipe 1 is connected to the fuel injection tank 6 through the inlet, and then supplies fuel to the chamber of the fuel injection tank 6 through a T-shaped outlet pipe.

[0027] Specifically, in this embodiment, for ease of connection and installation, the T-shaped oil outlet pipe is assembled from an internal tee connector 4 and two side oil outlet pipes 5. Specifically, the internal tee connector 4 is T-shaped, with both ends connected to the side oil outlet pipes 5, and the remaining end connected to the inlet pipe 1. Each side oil outlet pipe 5 has an end outlet groove 5-2 on its outer end face and two side wall grooves 5-1 on its circumferential outer wall. The side wall grooves 5-1 are parallel to the outlet grooves of the injection tank 6. The two side wall grooves 5-1 on the outer end face of each side oil outlet pipe are symmetrically arranged relative to the axis of the side oil outlet pipe. That is, when the side oil outlet pipe has side wall grooves 5-1, oil can exit from both sides simultaneously, avoiding excessive impact on the injection tank 6 caused by single-sided oil exit, thus preventing uneven liquid distribution.

[0028] like Figure 6As shown, during processing, the side oil outlet pipe 5 can be made of seamless steel pipe as the main body. The seamless steel pipe is cut according to the design requirements, and a long groove 5-1 is machined on the side wall. A sealing plate plug is fixedly installed on one end of the pipe, and an end liquid outlet groove 5-2 is machined on the sealing plate plug. Then, the unsealed end is connected and assembled with the internal tee structure 4.

[0029] When the existing inlet pipe is directly connected to the oil spray tank 6, the liquid exiting from the outlet of the existing inlet pipe will directly impact the outlet tank. On the one hand, the pressure at the outlet will be too high, resulting in uneven oil curtain pressure. On the other hand, the impact force will create turbulence within the oil spray tank 6, affecting the smoothness of the oil flow within the tank, further impacting the uniformity and smoothness of the oil curtain formation, ultimately affecting the processing quality of the wire cutting machine.

[0030] In this embodiment, the oil from the inlet pipe first supplies oil to the side outlet pipes 5 on both sides through the inner tee connector 4. During the inlet process, the pipe wall impacted by the greater force is the inner tee connector 4, and the resulting turbulence is also within the inner tee connector 4. After the oil enters the inner tee connector 4, it is guided by the inner tee connector 4 to flow out from the side outlet pipes 5 on both sides. The turbulence generated during the inlet process is controlled within the inner tee connector 4 and will not directly affect the oil outlet of the spray tank 6. When oil is discharged from the side outlet pipes 5, compared with the original tubular oil outlet, a long groove is used for oil discharge, making the oil discharge shape more in line with the shape of the main outlet tank. Oil can be supplied and replenished along the length of the main outlet tank, which helps to improve the stability and uniformity of the oil during discharge. The end outlet groove 5-2 designed at the outer end replenishes the oil pressure at both ends, further ensuring the stability and uniformity of the oil during discharge.

[0031] This type of oil spraying device for wire cutting machines has a reasonable structural design. The T-shaped double-headed outlet design at the outlet of the oil inlet pipe 1 effectively alleviates the turbulence caused during the oil inlet process. The side wall grooves 5-1 and end liquid outlet grooves 5-2 of the pipe fittings at both ends of the T-shaped outlet allow the oil to flow out smoothly. The end liquid outlet grooves 5-2 also replenish the oil at both ends, preventing the end pressure from being too low. This further evens out the uniformity and stability of the liquid outlet, which is beneficial for stabilizing and improving the cutting quality.

[0032] Example 2:

[0033] like Figure 4 and Figure 5 The oil spraying device for a wire tangent machine shown is Embodiment 2 of this utility model. Based on Embodiment 1, Embodiment 2 further improves the design of the main oil outlet groove, allowing the oil to be evenly discharged from the T-shaped oil outlet pipe, thus forming a uniform and stable oil curtain.

[0034] Specifically, in Embodiment 2, the scoop-shaped structure of the oil injection tank 6 has a lower bottom plate and an upper inclined plate 6-3 at the position corresponding to the liquid outlet tank. The upper inclined plate 6-3 is above the lower bottom plate, and there is a gap between the lower edge of the upper inclined plate 6-3 and the upper end face of the lower bottom plate. This gap is the channel for oil to flow out.

[0035] The lower base plate extends outward from the projection position of the lower edge of the upper inclined plate 6-3 onto the lower base plate, forming a flow plate 6-1. The outer end of the flow plate 6-1 bends downward to form a lower guide plate 6-2, and the angle between the flow plate 6-1 and the lower guide plate 6-2 is an obtuse angle. The flow plate 6-1 supports the oil flowing out of the gap and guides it together with the adjusting plate 2, resulting in a more stable and smooth oil surface. The oil then extends along the lower guide plate 6-2 to form an oil curtain.

[0036] To further control the oil flow, an adjustable plate 2 can be adjusted on the upper inclined plate 6-3. The outlet height can be adjusted by changing the position of the adjustable plate 2. Specifically, the adjustable plate 2 includes an integrally structured adjustable inclined plate 2-1 and an adjustable flat plate 2-2. The adjustable inclined plate 2-1 is adjustablely mounted on the outer surface of the upper inclined plate 6-3 and is parallel to the upper inclined plate 6-3. The adjustable flat plate 2-2 is fixed to the lower edge of the adjustable inclined plate 2-1 and parallel to the horizontal plate 6-1. The adjustable positioning of the adjustable inclined plate 2-1 is achieved through the cooperation of waist holes 3 and bolts. Several waist holes 3 are formed on the adjustable inclined plate 2-1, and bolts are fitted inside the waist holes 3 to position and fix the adjustable inclined plate 2-1 to the upper inclined plate 6-3. The length direction of the projection of the waist holes 3 onto the lower base plate is the oil flow direction. The gap between the horizontal plate 6-1 and the adjustable flat plate 2-2 forms a general outlet channel for oil flow. By adjusting the position of the adjusting plate 2, the gap between the horizontal plate 6-1 and the adjustable plate 2-2 can be adjusted, thereby adjusting the discharge height of the main discharge tank.

[0037] Thus, at the outlet tank, the horizontal plate 6-1 and the adjusting plate 2 create a stable plane during oil discharge. The oil then flows downwards along the lower guide plate 6-2, further guided by the flat plate of the horizontal plate 6-1, ensuring an effective and stable oil surface before flowing downwards to form an oil curtain. Simultaneously, the position of the adjusting plate 2 relative to the upper inclined plate 6-3 is adjustable, allowing for adjustable and controllable oil surface height, which in turn enables control over the overall outlet tank's discharge height.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
