Description

Technical Field

[0001] This utility model relates to the field of cutting fluid nozzle technology, specifically to a cutting fluid nozzle with adjustable flow rate. Background Technology

[0002] The hot-rolled coil grinding large cutting process uses a special process and a specially made abrasive belt to effectively control the cutting of black skin pits on the surface of stainless steel. During the cutting process, a cutting fluid nozzle is used to rinse and cool the grinding area.

[0003] A search revealed that CN215547189U discloses a cutting fluid pressure self-adjusting nozzle, comprising an inlet pipe, an adjusting ring, and a limiting ring, which are sequentially sleeved on the outer wall of the nozzle connector from top to bottom. The lower end of the inlet pipe is fixedly engaged in the groove of the adjusting ring. A sliding groove is formed on the side wall of the nozzle connector. A limiting rivet is inserted into the side wall of the inlet pipe and passes through the side wall of the inlet pipe to the sliding groove of the nozzle connector. A tension spring is also sleeved on the outer wall of the nozzle connector.

[0004] In actual production, as the grinding time of the grinding belt on the product increases, the surface of the grinding belt will be worn due to long-term grinding. As the degree of wear increases, the temperature generated by the grinding belt when grinding the product will also increase. However, the above-mentioned nozzle cannot adjust the flow rate of the cutting fluid. When the flow rate remains unchanged, the grinding effect and cooling effect will be reduced when the temperature rises.

[0005] Based on this, the present invention designs a cutting fluid nozzle with adjustable flow rate to solve the above problems. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0037] The present invention will be further described below with reference to the embodiments.

[0038] Example 1: Please refer to the accompanying drawings in the instruction manual. Figure 1 - Figure 5An adjustable flow rate cutting fluid nozzle includes a main nozzle 1; a spraying mechanism 2 mounted on the main nozzle 1; an adjustment box 3 fixedly mounted on the top of the main nozzle 1, the adjustment box 3 having a positioning plate for fixing the device inside a grinding device, the connection between the positioning plate and the adjustment box 3 being adjustable according to specific conditions; a liquid adjustment mechanism 4 and a gas adjustment mechanism 5 mounted on the adjustment box 3, the liquid adjustment mechanism 4 having a temperature sensor, the detection end of the temperature sensor being located at the drive end of the grinding machine, capable of real-time monitoring of the temperature generated by the grinding belt, the temperature sensor transmitting the real-time temperature to the control system of the grinding device, the control system controlling the liquid adjustment mechanism 4 to control the flow rate of the cutting fluid; the liquid adjustment mechanism 4 includes components fixedly mounted on the left side wall of the adjustment box 3. The system includes: a mounting box 41; a waterproof motor 42 fixedly mounted on the left side wall of the mounting box 41; an adjusting block 43 fixedly mounted inside the adjusting box 3; an adjusting plate 48 rotatably mounted inside the adjusting block 43; a drain pipe 44 fixedly mounted on the front wall of the adjusting block 43, with one end of the drain pipe 44 away from the adjusting block 43 fixedly mounted on the top wall of the main spray pipe 1; a supply pipe 46 fixedly mounted on the rear wall of the adjusting block 43, which can be connected to an external pipeline for supplying cutting fluid; an adjusting rod 45 fixedly mounted on the outer wall of the adjusting plate 48, with the outer wall of the adjusting rod 45 rotatably connected to the left side wall of the adjusting block 43 and the left side wall of the adjusting box 3; and a manual adjusting assembly 47 on the adjusting box 3.

[0039] In practical use, the device is installed at the desired location. The bottom of the main nozzle 1 is aligned with the grinding position of the grinding belt. Cutting fluid is discharged into the regulating block 43 through the supply pipe 46, and then discharged into the main nozzle 1 through the drain pipe 44. Part of the cutting fluid is discharged from the bottom of the main nozzle 1 to cool the grinding belt and hot-rolled coil and wash away the cutting debris. The other part is washed and cooled by the spray mechanism 2. As the grinding belt wears down, the friction between it and the hot-rolled coil increases, resulting in more heat. The temperature sensor detects this increase in temperature. The system controls the waterproof motor 42 to drive it, which in turn rotates the adjusting rod 45. The adjusting plate 48 begins to flip, increasing the gap between the adjusting plate 48 and the adjusting block 43, thereby increasing the amount of cutting fluid discharged into the main spray pipe 1 until the temperature of the grinding belt returns to the set range. At this point, the control system will control the waterproof motor 42 to stop working, ensuring normal cooling and grinding effects. By setting the manual adjustment component 47, manual adjustment can be achieved, which can be used according to specific needs. This manual-automatic approach increases the overall functionality.

[0040] Example 2: Based on Example 1, please refer to the accompanying drawings in the specification. Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The manual adjustment assembly 47 includes a fixed sleeve 471 fixedly installed on the right side wall of the adjustment box 3, an adjustment rod 45 whose outer wall extends to the right side of the adjustment box 3, and the right outer wall of the adjustment rod 45 is located inside the fixed sleeve 471; a transmission sleeve 474 slidably connected inside the fixed sleeve 471, the left side wall of the transmission sleeve 474 having a rectangular groove, and the right end of the adjustment rod 45 being rectangular; an auxiliary knob 473 fixedly installed on the right end of the transmission sleeve 474; a movable sleeve 472 rotatably installed on the outer wall of the auxiliary knob 473, the movable sleeve 472 and the fixed sleeve 471 being slidably connected; and a spring 475 fixedly installed on the right side wall inside the cavity of the movable sleeve 472, the left end of the spring 475 being rotatably connected to the right side wall of the adjustment box 3, and the spring 475 being slidably connected to the transmission sleeve 474 and the adjustment rod 45.

[0041] The gas regulating mechanism 5 includes a regulating block 51 fixedly installed inside the regulating box 3; a regulating plate 54 rotatably installed inside the regulating block 51; an exhaust pipe 53 fixedly installed on the front wall of the regulating block 51, with one end of the exhaust pipe 53 away from the regulating block 51 fixedly connected to a liquid supply pipe 46; a gas supply pipe 52 fixedly installed on the rear wall of the regulating block 51, which can supply gas to the inside of the regulating block 51 through a gas pipeline; and a regulating rod 55 fixedly installed on the left outer wall of the regulating plate 54, with the outer wall of the regulating rod 55 rotatably connected to the left wall of the regulating block 51 and the left wall of the regulating box 3. The outer wall of the regulating rod 55 extends into the interior of the mounting box 41, and a limiting groove 60 is formed on the left wall of the regulating rod 55. The limiting groove 60 is rectangular.

[0042] The gas regulating mechanism 5 also includes a limiting sleeve 57 slidably connected to the left outer wall of the regulating rod 55; a spring 59 rotatably installed on the wall surface of the limiting sleeve 57 and the regulating box 3, the spring 59 and the regulating rod 55 being slidably connected; a limiting rod 56 fixedly installed on the left wall surface inside the cavity of the limiting sleeve 57, the limiting rod 56 being rectangular, the outer wall of the limiting rod 56 being slidably connected to the inside of the limiting groove 60; an electromagnet 58 fixedly installed inside the limiting sleeve 57; a movable rod 61 rotatably installed on the left wall surface of the regulating box 3; a transmission belt 62 sleeved on the outer wall of the movable rod 61 and the regulating rod 45 via a pulley; and friction wheels 63 fixedly installed on the outer walls of the limiting sleeve 57 and the movable rod 61, the rear friction wheel 63 being a cone shape with a larger left side and a smaller right side, and the front friction wheel 63 being a cone shape with a smaller left side and a larger right side.

[0043] In practical use, by pressing the auxiliary knob 473 to the left, the spring 475 is compressed until the right end of the adjusting rod 45 enters the transmission sleeve 474. At this time, the auxiliary knob 473 can be rotated, and the adjusting rod 45 rotates with the adjusting plate 48. The operation is simple and convenient. Gas can be supplied to the adjusting block 51 through the air supply pipe 52. The gas will enter the liquid supply pipe 46 through the exhaust pipe 53 and mix with the cutting fluid, which can atomize the cutting fluid. The atomized cutting fluid can reduce the cutting temperature and reduce the residual stress on the workpiece surface, improve the cooling effect, and at the same time reduce the adhesion between the workpiece and the grinding belt, reduce the resistance between the grinding belt and the workpiece, and reduce the wear speed of the tool. During operation, when the cutting fluid flow rate is adjusted via the liquid regulating mechanism 4, the electromagnet 58 is energized. The electromagnet 58 generates magnetic force to attract the second regulating rod 55. The limiting sleeve 57 and the limiting rod 56 move towards the second regulating rod 55, and the second spring 59 is compressed until the conical surfaces of the two sets of friction wheels 63 are in contact. Under the action of the transmission belt 62, the drive end of the waterproof motor 42 drives the movable rod 61 and the first regulating rod 45 to rotate synchronously. With the cooperation of the two sets of friction wheels 63, the limiting sleeve 57 drives the limiting rod 56 to rotate. Under the limitation of the limiting groove 60, the second regulating rod 55 drives the second regulating plate 54 to rotate, realizing the synchronous adjustment of gas and cutting fluid, ensuring the atomization effect, and facilitating the use of the device.

[0044] Example 3: Based on Example 1, please refer to the accompanying drawings in the specification. Figure 2 , Figure 3 and Figure 11 The spraying mechanism 2 includes four sets of connecting pipes 21 rotatably mounted on the bottom outer wall of the main spray pipe 1, the four sets of connecting pipes 21 being distributed in an equal arc state; liquid inlet pipes 22 fixedly mounted on the outer wall of the four sets of connecting pipes 21, the ends of the four sets of liquid inlet pipes 22 away from the same set of connecting pipes 21 being fixedly connected to the lower outer wall of the main spray pipe 1; bamboo joint spray pipes 23 fixedly mounted at the bottom of the four sets of connecting pipes 21; and an angle adjustment mechanism 24 provided on the main spray pipe 1.

[0045] The angle adjustment mechanism 24 includes an adjustment sleeve 241 rotatably mounted on the outer wall of the main nozzle 1, with a friction pad provided between the adjustment sleeve 241 and the main nozzle 1; a connecting plate 242 fixedly mounted on the bottom of the adjustment sleeve 241, the connecting plate 242 being rotatably connected to the outer wall of the main nozzle 1, the outer wall of the connecting plate 242 having four raised arc surfaces distributed in an equal arc state; four sets of fixing plates 243 fixedly mounted on the top of the lower end of the main nozzle 1, the four sets of fixing plates 243 being distributed in an equal arc state; and a connecting rod 244 slidably connected to the four sets of fixing plates 243.

[0046] The angle adjustment mechanism 24 also includes a limiting plate 245 fixedly installed on the wall surface near the four sets of connecting rods 244; a rotating column 246 rotatably installed inside the four sets of limiting plates 245; a spring 248 fixedly installed on the wall surface near the four sets of limiting plates 245 and the same set of fixing plates 243, all four sets of springs 248 being slidably connected to the same set of connecting rods 244; and a connecting rod 247 rotatably installed on the wall surface away from the four sets of connecting rods 244, all four sets of connecting rods 247 being rotatably connected to the corresponding connecting pipe 21.

[0047] In practical use, the cutting fluid is discharged into the connecting pipe 21 through four sets of inlet pipes 22, then into the bamboo-joint spray pipes 23 through the connecting pipes 21, and finally sprayed out through the four sets of bamboo-joint spray pipes 23 for cooling and rinsing. Since the four sets of bamboo-joint spray pipes 23 are located around the main spray pipe 1, they can rinse around the grinding belt, improving the rinsing effect and rinsing range. In addition, by rotating the adjusting sleeve 241, the connecting plate 242 starts to rotate, and the protruding part of the connecting plate 242 approaches and connects with the rotating column 246. When the rotating column 246 is subjected to force, the limiting plate 245 and the first connecting rod 244 move away from the connecting plate 242. The third spring 248 is compressed, the second connecting rod 247 moves away from the fixed plate 243, and the upper end of the connecting tube 21 flips away from the fixed plate 243, thereby changing the angle of the four sets of connecting tubes 21. This allows for synchronous angle adjustment of the four sets of connecting tubes 21, enabling synchronous fine-tuning of the overall rinsing range. The device can be operated according to specific needs, making it convenient to use.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
