Description

Technical Field

[0001] This utility model relates to the field of wire cutting machine technology, and in particular to a water spraying device for a wire cutting machine. Background Technology

[0002] In online cutting operations, depending on the material of the workpiece being processed, oil cooling or water cooling can be used for cooling. Water cooling is generally suitable for processing non-metallic materials, such as glass and ceramics, in cutting and grinding processes. Spraying water for cooling will not adversely affect these materials and can effectively reduce processing temperature, making it particularly suitable for wafer cutting. Oil cooling is suitable for processing metallic materials, effectively reducing friction and wear during processing and forming a protective film on the metal surface. The oil film evaporates slowly, allowing it to continue working in the processing area, providing a stable cooling effect and preventing rust and corrosion. Different cooling devices need to be designed based on the characteristics of different cooling media, such as viscosity. Oil-cooled spray devices use viscous oil that needs to be pressurized and extruded. Water-cooled spray devices require a structure that stores cooling water until it overflows to form a cooling curtain, ensuring that the pressure of the cooling curtain is uniform and reliable.

[0003] After the water spray device is assembled onto the wire cutter and operates for a period of time, impurities or minerals may accumulate in the water chamber or adhere to its inner wall during the temporary storage and overflow process. At this point, the water spray device needs to be removed and the chamber cleaned to prevent impurities from affecting normal water cooling operation. Existing water spray devices typically have mounting ears on both sides of the water chamber, with bolt holes for direct bolt fixation to the wire cutter frame. During disassembly and assembly, the bolt holes on both sides must be aligned one by one, a cumbersome process. For wire cutters, cleaning the water spray device, and thus its installation and disassembly, are essential maintenance steps. Therefore, simplifying these steps is crucial for streamlining maintenance. Utility Model Content

[0004] 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 a water spraying device for a wire cutting machine, which can be conveniently and quickly positioned and installed with the frame, effectively simplifying the positioning process and simplifying the disassembly and maintenance process.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a water spraying device for a wire cutting machine, installed on the frame of the wire cutting machine, including a water spraying tank assembly, on both sides of the water spraying tank assembly are symmetrically fixed with mounting ears; including fixed brackets on both sides of the water spraying tank assembly, each fixed bracket has a slot for the corresponding mounting ear to be inserted and fitted from top to bottom, and the slot is also provided with a tightening bolt for tightening and positioning the mounting ear and the slot when they are inserted and fitted together.

[0006] In the above solution, addressing the drawback of the original water spray device for wire cutting machines being difficult to disassemble and maintain, a fixed bracket is installed on the frame, and mounting ears are designed on the water spray trough assembly. The mounting ears and the slots of the fixed bracket are then inserted into each other, allowing for the overall disassembly and assembly of the water spray trough assembly relative to the frame. Since the fixed bracket can be directly fixed to the frame after adjustment, the installation of the water spray trough assembly only requires alignment of the mounting ears with the slots, eliminating the need for the complex alignment of multiple bolt holes previously required. This makes disassembly and positioning simpler and more convenient, effectively simplifying the disassembly, assembly, and maintenance process.

[0007] Furthermore, the fixed bracket includes a fixed support and a mounting support. The fixed support has at least two first elongated holes along the height direction of the frame, and the frame has a first mounting hole corresponding to the first elongated holes. The fixed support is adjustablely connected to the frame by first bolts fitting within the first elongated holes and the first mounting hole. The mounting support is adjustablely fixed to the fixed support, and the slot is provided on the mounting support. The engagement of the first elongated holes and the first mounting hole allows for height adjustment of the fixed support relative to the frame.

[0008] Furthermore, the mounting bracket is an L-shaped bent component, with a second elongated hole in the vertical portion of the L-shaped bent component, and a second mounting circular hole on the fixed bracket. The mounting bracket and the fixed bracket are adjustablely connected by a second bolt fitted within the second mounting circular hole and the second elongated hole. Two insert plates are obliquely fixed between the vertical and horizontal portions of the L-shaped bent component, forming a slot between the two insert plates, the inner surface of the vertical portion of the L-shaped bent component, and the upper surface of the horizontal portion for mounting lugs to engage. The engagement of the second mounting circular hole and the second elongated hole allows for horizontal adjustment of the mounting bracket relative to the fixed bracket.

[0009] Preferably, the distance between the two insert plates on each mounting bracket is greater than the thickness of the mounting ear, and at least one insert plate has a positioning hole, wherein a tightening bolt is provided in the positioning hole to tighten the mounting ear and the slot after the mounting ear is inserted.

[0010] Preferably, the fixed support is a Z-shaped bent part, with a first elongated hole on one side of the Z-shaped bent part and a second mounting hole on the other side of the Z-shaped bent part. The mounting support is adjustablely connected to the fixed support by fitting a second bolt in the second mounting hole and the second elongated hole.

[0011] Preferably, the fixed support is a flat plate with a second mounting round hole and a first elongated hole. The second mounting round hole and the first elongated hole are misaligned without interference. The mounting support is adjustablely connected to the fixed support by a second bolt fitted in the second mounting round hole and the second elongated hole.

[0012] Furthermore, the water spray tank assembly includes a main tank body, with an inlet pipe connected to one side and an outlet side on the other, the outlet side having a long, groove-shaped outlet. The main tank body is equipped with a first and a second baffle plate arranged vertically and offset from top to bottom. The first baffle plate includes a first vertical fixing part and a first lower baffle part, both integrally structured. The first vertical fixing part is fixed to the side of the main tank body with the inlet pipe, and the angle between the first fixing part and the first lower baffle part is obtuse. The second baffle plate includes a second mounting part, a second baffle part, and a second lower baffle part, all integrally structured and bent and connected. The second mounting part is fixed to the inner wall of the main tank body, and the second baffle part is vertically positioned and blocks the inlet pipe from the outlet. The angle between the second lower baffle part and the second baffle part is obtuse. A gap exists between the lower end face of the first lower baffle part and the upper end face of the second lower baffle part for cooling water to pass through. Cooling water enters the main tank through the inlet pipe, and after being guided by the first and second baffles to dissipate excessive impact, it overflows upwards and flows out from the outlet on the outlet side, forming a cooling water curtain for the wire cutter. Under the obstruction of the baffles and the action of gravity, any impurities that may be present in the cooling water will be deposited in the main tank, reducing pollution caused during cooling.

[0013] Furthermore, the main tank has corner guide plates obliquely fixed between the side of the inlet pipe and the inner bottom surface; the main tank also has corner guide plates obliquely fixed between the side of the outlet side and the inner bottom surface; the angle α between the corner guide plates and the inner bottom surface is 135°. By setting the corner guide plates, a 135° obtuse angle is formed on both sides of the bottom of the main tank, thereby avoiding excessive water flow disturbance caused by right angles, which could disturb the deposited impurities and affect the sedimentation effect.

[0014] Furthermore, a flow-guiding extension plate is fixed to the main tank corresponding to the water outlet side. Flow-guiding side plates that limit water flow are fixed to both sides of the extension plate. The extension plate has a Z-shaped structure, comprising an integral upper plate, a connecting inclined plate, and a lower plate. The upper end face of the upper plate is fixed to the lower end face of the main tank's water outlet side. The connecting inclined plate continues from the upper plate away from the main tank's water outlet side and points diagonally downwards. The lower plate continues from the end of the connecting inclined plate and extends away from the main tank. The flow-guiding extension plate further guides the cooling water overflowing from the outlet, forming a more stable and uniform water curtain that flows diagonally downwards and outwards.

[0015] Furthermore, the lower plate includes an integrally structured lower connecting part and a lower guide part. The lower connecting part is connected to the end of the connecting inclined plate and extends horizontally away from the main tank. The lower guide part extends outward from the lower connecting part and points obliquely downward.

[0016] The beneficial effects of this utility model are that the water spraying device for a wire cutting machine provided by this utility model has a reasonable structural design. The mounting bracket is positioned on the frame, and the approximate positioning of the water spraying tank assembly is achieved through the cooperation of the fixed bracket and the mounting bracket. When installing the water spraying tank assembly, simply insert the mounting ears into the mounting slots on the mounting brackets to place the water spraying tank and the frame. Subsequently, the water spraying tank assembly can be fixed by positioning bolts. The disassembly and positioning process between the water spraying tank assembly and the frame is convenient and quick, without the need for cumbersome hole alignment, which can effectively simplify the maintenance process of the cooling device.

[0017] Meanwhile, the water spraying device for a wire cutting machine provided by this utility model effectively slows down the inlet water flow rate through two staggered baffles in the water spraying tank assembly. Furthermore, the corner guide plates effectively reduce the disturbance of cooling water in the corners of the water spraying tank, which affects the deposition of impurities. The cooling water overflows from the bottom up in the water spraying tank assembly, and the impurities in the water settle in the tank. The cooling water overflowing from the outlet is then guided by the extended guide plate to form a water curtain. The water curtain formed in this way is more uniform, stable, and reliable.

[0024] 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.

[0025] like Figures 1 to 4 The water spray device for a wire cutting machine shown is the preferred embodiment of this utility model.

[0026] like Figure 1 and Figure 4 As shown, this embodiment is installed on the wire cutting machine frame 27, including a water spray tank assembly and fixed brackets on both sides of the water spray tank assembly. Mounting ears 9 are symmetrically fixed on both sides of the water spray tank assembly. Each fixed bracket has a slot for the corresponding mounting ear 9 to be inserted from top to bottom. The slot is also provided with a tightening bolt 8 to tighten and position the mounting ear 9 against the slot when they are inserted.

[0027] In the arrangement of the fixed bracket and its slot, it is preferable, but not limited, to use a combination of fixed support and mounting bracket to form the fixed bracket.

[0028] The fixed support has two first elongated holes 1 along the height of the frame 27. The frame 27 has a first mounting hole corresponding to the first elongated hole 1. The fixed support is adjustablely connected to the frame 27 by first bolts 2 fitted into the first elongated hole 1 and the first mounting hole. The mounting support 6 can preferably be an L-shaped bent piece, wherein the vertical part of the L-shaped bent piece has a second elongated hole 4. The fixed support has a second mounting hole 14. The mounting support 6 and the fixed support are adjustablely connected by second bolts 5 fitted into the second mounting hole 14 and the second elongated hole 4.

[0029] Specifically, the fixed support can be a Z-shaped bent part 3 or a flat part 15. During actual assembly, the appropriate option can be selected based on the layout of the frame 27. For example, in this embodiment, such as... Figure 1 As shown, among the fixed supports on both sides, one side uses a Z-shaped bent part 3, and the other side uses a flat part 15.

[0030] One side of the Z-shaped bending part 3 has a first elongated hole 1 on one side plane, and the other side plane of the Z-shaped bending part 3 has a second mounting hole 14. The mounting support 6 is adjustablely connected to the fixed support by fitting a second bolt 5 in the second mounting hole 14 and the second elongated hole 4.

[0031] On one side of the flat plate 15, there are a second mounting round hole 14 and a first elongated hole 1 respectively. The second mounting round hole 14 and the first elongated hole 1 are distributed without interference and are misaligned. The mounting support 6 is adjustablely connected to the fixed support by fitting a second bolt 5 in the second mounting round hole 14 and the second elongated hole 4.

[0032] The engagement of the first elongated slot 1 with the first mounting hole allows for height adjustment of the fixed support relative to the frame 27. The engagement of the second mounting hole 14 with the second elongated slot 4 allows for horizontal position adjustment of the mounting support 6 relative to the fixed support.

[0033] Two insert plates 7 are obliquely fixed between the vertical and horizontal portions of the L-shaped bent component of the mounting bracket 6. A slot is formed between the two insert plates 7, the inner surface of the vertical portion of the L-shaped bent component, and the upper surface of the horizontal portion for the mounting ear 9 to be inserted. This slot allows the mounting ear 9 to be inserted from top to bottom. To facilitate positioning after insertion, the distance between the two insert plates 7 on each mounting bracket 6 is greater than the thickness of the mounting ear 9, and positioning holes 10 are provided on both sides of the insert plates 7. The positioning holes 10 are typically threaded holes. After the mounting ear 9 is inserted, either one positioning hole 10 or both positioning holes 10 can be selected, and a tightening bolt 8 can be screwed in. The tightening bolt 8 is used to position and tighten the mounting ear 9 to the slot, achieving the final positioning of the water spray tank assembly.

[0034] Thus, this embodiment addresses the drawback of the original water spray device for wire cutting machines being difficult to disassemble and maintain. By setting a fixed bracket on the frame 27 and designing mounting ears 9 on the water spray trough assembly, the mounting ears 9 are used to engage with the slots of the fixed bracket, enabling the overall disassembly and assembly of the water spray trough assembly relative to the frame 27. Since the fixed bracket can be directly fixed to the frame 27 after adjustment, the installation of the water spray trough assembly only requires aligning the mounting ears 9 with the slots, eliminating the need for the original complex alignment of multiple bolt holes. This makes disassembly and positioning simpler and more convenient, effectively simplifying the disassembly, assembly, and maintenance process.

[0035] Meanwhile, in response to the problem of impurity handling during the water spraying process, this embodiment has made further improvements to the design of the water spray tank assembly, so that it can ultimately form a more stable, reliable and clean cooling water curtain.

[0036] Specifically, such as Figure 2 and Figure 3 As shown, the water spray tank assembly includes a main tank body 13. One side of the main tank body 13 is connected to an inlet pipe 12, and the other side is the outlet side, which has a long, groove-shaped outlet 11. The main tank body 13 is equipped with a first and a second baffle plate arranged vertically and offset from top to bottom. A gap exists between the lower end face of the first lower baffle section 20 and the upper end face of the second lower baffle section 18 to allow cooling water to pass through. Cooling water enters the main tank body 13 through the inlet pipe 12, is guided by the first and second baffle plates to remove excessive impact force, and then overflows upwards, flowing out from the outlet 11 on the outlet side. Due to the obstruction of the baffle plates and the effect of gravity, any impurities that may be present in the cooling water will be deposited inside the main tank body 13, reducing contamination during cooling.

[0037] Specifically, such as Figure 3 As shown, the first baffle plate includes a first vertical fixing part 19 and a first lower baffle part 20, which are integral structures. The first vertical fixing part 19 is fixed on the side of the main tank 13 with the water inlet pipe 12. The angle between the first fixing part and the first lower baffle part 20 is an obtuse angle. The second baffle plate includes a second mounting part 16, a second baffle part 17 and a second lower baffle part 18, which are integral structures and bent and connected. The second mounting part 16 is fixed on the inner wall of the main tank 13. The second baffle part 17 is vertically arranged and blocks the water inlet pipe 12 and the water outlet 11. The angle between the second lower baffle part 18 and the second baffle part 17 is an obtuse angle.

[0038] A corner guide plate 21 is obliquely fixed between the side of the main tank 13 with the water inlet pipe 12 and the inner bottom surface. A corner guide plate 21 is also obliquely fixed between the side of the main tank 13 with the water outlet and the inner bottom surface. The angle α between the corner guide plate 21 and the inner bottom surface is preferably 135°. By setting the corner guide plate 21, a 135° obtuse angle can be formed on both sides of the bottom of the main tank 13, thereby avoiding excessive water flow disturbance caused by right angles, which could disturb the deposited impurities and affect the sedimentation effect.

[0039] Cooling water overflows from the outlet 11 on the outlet side of the main tank 13. A flow-guiding extension plate is also fixed on the outlet side of the main tank 13, and flow-guiding side plates 23 are fixed on both sides of the flow-guiding extension plate to limit the water flow. The flow-guiding extension plate and flow-guiding side plates 23 further form a channel to guide the flow of cooling water, extend the channel to guide the water flow, thereby further stabilizing the water output and ultimately forming a more stable and uniform cooling water curtain.

[0040] Specifically, the flow guide extension plate has a Z-shaped structure, which includes an integral upper plate 22, a connecting inclined plate 24, and a lower plate. The upper end face of the upper plate 22 is fixed to the lower end face of the water outlet side of the main tank 13. The connecting inclined plate 24 is connected to the upper plate 22 away from the water outlet side of the main tank 13 and points diagonally downward. The lower plate is connected to the end of the connecting inclined plate 24 and extends away from the main tank 13. The lower plate includes an integral lower connecting part 25 and a lower flow guide part 26. The lower connecting part 25 is connected to the end of the connecting inclined plate 24 and extends horizontally away from the main tank 13. The lower flow guide part 26 extends outward from the lower connecting part 25 and points diagonally downward.

[0041] After the cooling water flows out of the outlet 11, it is first guided horizontally by the upper plate 22, and then guided downward and outward by the connecting inclined plate 24. The angle of this guide is relatively large. It is then smoothly guided outward by the lower connecting part 25, and then flows smoothly downward and outward through the lower guide part 26 at a slight angle to form a cooling water curtain. The guide extension plate guides the cooling water overflowing from the outlet 11 through three changes of direction, ultimately forming a more stable and uniform water curtain that flows out obliquely downward and outward. The resulting cooling water curtain is uniform, stable, and of reliable quality.

[0042] 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.
