Description

Technical Field

[0001] The present application relates to the technical field of steel sawing, and more specifically, to a sawing cooling water retaining device. Background Art

[0002] Metal sawing machines are widely used in steel rolling workshops to cut the heads and tails of rolled pieces, take samples, and cut them into products of required lengths online, so as to obtain products with neat cross-sections. The sawing machine that cuts rolled pieces at room temperature is called a cold sawing machine, and the sawing machine that cuts rolled pieces at high temperature is called a hot sawing machine. When sawing, the saw blade rotates at high speed, and the linear speed is greater than 100m / s. The saw blade generates a lot of heat due to the high-speed friction between the saw blade and the metal material being sawed. If the saw blade is not cooled in time, it will seriously affect the service life of the saw blade, and even cause the saw blade to melt at high temperature, especially for hot sawing machines, where the saw blade is also affected by the high temperature of the metal material itself.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] The present application provides a sawing cooling water retaining device, such as Figure 1-3As shown, it includes: a supporting platform 1; a sawing mechanism, including a driving seat 21 and a saw blade 22, and the sawing mechanism is fixedly connected to the supporting platform 1 through the driving seat 21; a water retaining mechanism, which is covered on the upper part of the saw blade 22, and the water retaining mechanism is used to shield the saw blade 22; a cooling mechanism, which is arranged on the inner wall of the water retaining mechanism, and the cooling mechanism is used to spray cool the saw blade 22; a recovery mechanism, which is arranged inside the supporting platform 1, and the recovery mechanism is used to recover the coolant of the cooling mechanism; a cooling control module, which is used to obtain the surface temperature of the saw blade 22, and determine the spraying water pressure of the cooling mechanism according to the surface temperature of the saw blade 22; a water retaining control module, which is used to obtain the spraying water pressure of the cooling mechanism, and control the angle of the water retaining mechanism according to the spraying water pressure of the cooling mechanism.

[0063] In this embodiment, the drive seat 21 is fixedly connected to the support platform 1, and the drive seat 21 drives the saw blade 22 to saw the workpiece. The water pressure of the cooling mechanism is controlled by the cooling control module, and the angle of the water retaining mechanism is controlled by the water retaining control module to effectively block the splashing trajectory of the coolant.

[0064] In some embodiments of the present application, the water-blocking mechanism includes: a baffle 31, symmetrically arranged on both sides of the saw blade 22; a water receiving trough, hinged at the lower end of the baffle 31, and the water receiving trough is tilted downward toward one side of the driving seat 21; a telescopic mechanism, the telescopic mechanism includes a connecting plate 33 and a telescopic block 34, one end of the connecting plate 33 is fixedly connected to the upper end of the baffle 31, and the other end is fixedly connected to the telescopic block 34.

[0065] In this embodiment, two baffles 31 are provided, symmetrically arranged on both sides of the saw blade 22. The baffle 31 located on one side of the driving shaft 211 has a through hole at the corresponding position of the driving shaft 211. The driving shaft 211 passes through the through hole and is connected to the saw blade 22, thereby driving the saw blade 22 to rotate. A certain gap is left between the driving shaft 211 and the through hole of the baffle 31. The rear side of the baffle 31 is connected to the driving seat 21. The baffle 31 can be controlled to rotate around the driving shaft 211 through the driving seat 21, thereby adjusting the distance between the baffle 31 and the workpiece. The water receiving trough is a U-shaped trough with an upward opening. The splashing coolant can be directed to the side of the driving seat 21 behind the saw blade 22 through the water receiving trough to prevent the coolant from flowing onto the steel. The telescopic mechanism includes two connecting plates 33 respectively fixedly connected to the top of the baffle 31 and a telescopic block 34 located between the two connecting plates 33. The telescopic block 34 is controlled to telescope through the water retaining control module, thereby realizing the adjustment of the angle of the water retaining mechanism.

[0066] In some embodiments of the present application, the cooling mechanism includes: a high-pressure nozzle 41, which is arranged on the inner wall of the water retaining mechanism; a water pipe 42, one end of which is connected to the high-pressure nozzle 41; a water pump 43, which is arranged at the bottom of the support platform 1 and one end of which is connected to the other end of the water pipe 42; a water tank 44, which is arranged on one side of the water pump 43, and the water tank 44 is connected to the other end of the water pump 43.

[0067] In this embodiment, the water pipe 42, the water pump 43 and the water tank 44 are all arranged inside the support platform 1. The coolant in the water tank 44 is transferred to the water pipe 42 by the water pump 43 and sprayed out through the high-pressure nozzle 41. The high-pressure nozzle 41 is set toward the saw blade 22 to achieve cooling spray on the saw blade 22.

[0068] In some embodiments of the present application, the cooling mechanism also includes: an atomizing nozzle, which is arranged on the high-pressure nozzle 41, and the atomizing nozzle is used to control the atomization of the high-pressure nozzle 41; a nozzle opening and closing mechanism, which is connected to the atomizing nozzle, and the nozzle opening and closing mechanism is used to control the opening and closing of the atomizing nozzle.

[0069] In this embodiment, the opening and closing of the atomizing nozzle is controlled by the nozzle opening and closing mechanism. When the coolant needs to be atomized, the atomizing nozzle is controlled to open by the nozzle opening and closing mechanism to spray the saw blade 22 in an atomized manner.

[0070] In some embodiments of the present application, the recovery mechanism includes: a recovery chassis 51, which is arranged on the top of the support platform 1, and the recovery chassis 51 is located at a corresponding position of the inclined lower end of the water receiving trough; a recovery connecting pipe 52, one end of which is connected to the recovery chassis 51; a filtering mechanism 53, one end of which is connected to the recovery connecting pipe 52, and the other end is connected to the water tank 44, and the filtering mechanism 53 is used to filter the recovered coolant.

[0071] In this embodiment, the recovery chassis 51 is an inverted frustum that is wide at the top and narrow at the bottom. After the coolant is sprayed on the saw blade 22 to cool it, it flows to the recovery chassis 51 through the guide groove, enters the filter mechanism 53 through the recovery connecting pipe 52 to filter out impurities in the coolant, and the filtered coolant flows into the water tank 44 to realize the recycling of the coolant.

[0072] In some embodiments of the present application, the cooling control module is used to: obtain the surface temperature of the saw blade, and draw a temperature change curve of the current saw blade according to the surface temperature change of the saw blade; divide the temperature change curve of the saw blade into several sub-change curves according to a preset sliding time window, calculate the slope value of each sub-change curve, and screen out the sub-change curves with slope values ​​greater than zero to obtain a temperature rise change curve; set a temperature rise speed weight according to the temperature average value of the temperature rise change curve, multiply the temperature rise speed weight by the slope value of the corresponding temperature rise change curve to obtain a speed state coefficient of each temperature rise change curve; calculate the sum of each speed state coefficient in the temperature change curve of the saw blade to obtain the speed state coefficient of the temperature change curve of the saw blade; multiply the surface temperature of the current saw blade by the speed state coefficient to obtain the current saw blade state coefficient.

[0073] In this embodiment, the sub-change curve with rising temperature value is screened out by judging whether the slope value of the sub-change curve is greater than zero, and the average temperature value-temperature rise rate weight mapping table is pre-set. The temperature rise rate weight is set by obtaining the position of the average temperature value corresponding to the sub-change curve in the average temperature value-temperature rise rate weight mapping table. The temperature rise rate weight represents the allowable temperature change rate corresponding to each average temperature value. The higher the average temperature value, the greater the corresponding temperature rise rate weight. The speed state coefficient represents the temperature rise rate of the temperature rise change curve. The larger the value, the faster the temperature rise rate. The surface temperature of the current saw blade is multiplied by the speed state coefficient to obtain the current saw blade state coefficient. The surface temperature and temperature rise rate of the saw blade are combined to facilitate the subsequent setting of the water pressure of the cooling mechanism.

[0074] In some embodiments of the present application, the cooling control module is also used to: obtain a preset state coefficient threshold, calculate the difference between the current saw blade state coefficient and the preset state coefficient threshold; determine whether the difference between the current saw blade state coefficient and the preset state coefficient threshold is greater than a first preset threshold, if the difference between the current saw blade state coefficient and the preset state coefficient threshold is greater than the first preset threshold, then set the first water pressure as the spray water pressure of the cooling mechanism; if the difference between the current saw blade state coefficient and the preset state coefficient threshold is less than or equal to the first preset threshold, then determine whether the difference between the current saw blade state coefficient and the preset state coefficient threshold is greater than the second preset threshold; if the difference between the current saw blade state coefficient and the preset state coefficient threshold is greater than the second preset threshold, then set the second water pressure as the spray water pressure of the cooling mechanism; if the difference between the current saw blade state coefficient and the preset state coefficient threshold is less than or equal to the second preset threshold, then set the third water pressure as the spray water pressure of the cooling mechanism.

[0075] In this embodiment, the first preset threshold is greater than the second preset threshold, the first water pressure, the second water pressure, and the third water pressure decrease successively, and the spray water pressure of the cooling mechanism is determined by the difference between the current saw blade state coefficient and the preset state coefficient threshold. The larger the difference, the higher the spray water pressure, and the better the cooling effect on the saw blade 22.

[0076] In some embodiments of the present application, the nozzle opening and closing mechanism is used to: when the spray water pressure of the cooling mechanism is the third water pressure, control the atomizing nozzle to open; when the spray water pressure of the cooling mechanism is the first water pressure or the second water pressure, control the atomizing nozzle to close.

[0077] In this embodiment, when the spraying water pressure of the cooling mechanism is the third water pressure, it indicates that the surface temperature and temperature rise rate of the saw blade are not high, and an atomizing nozzle is selected to perform atomizing spraying on the saw blade 22, which effectively prevents splashing of the coolant and achieves a better cooling effect.

[0078] In some embodiments of the present application, the water retaining control module is used to: obtain the height data of the current workpiece 6 to be cut, calculate the difference between the height of the current water retaining mechanism and the height of the workpiece 6 to be cut, and determine whether the difference between the height of the current water retaining mechanism and the height of the workpiece 6 to be cut is greater than a preset height threshold; if the difference between the height of the current water retaining mechanism and the height of the workpiece 6 to be cut is less than or equal to the preset height threshold, determine the optimal height of the water retaining mechanism according to the height of the workpiece 6 to be cut; and adjust the height of the water retaining mechanism according to the optimal height of the water retaining mechanism.

[0079] In this embodiment, the height of the water retaining mechanism is the distance between the front end of the baffle plate 31 and the support platform 1. The height of the water retaining mechanism is adjusted by controlling the driving seat 21 through the water retaining control module so that the water retaining mechanism reaches an optimal height.

[0080] In some embodiments of the present application, the water retaining control module is further used to: obtain the current spray water pressure of the cooling mechanism, and determine the optimal angle of the current water retaining mechanism according to the spray water pressure of the cooling mechanism combined with the angle calculation formula, wherein the angle calculation formula is specifically:

[0081]

[0082] Among them, θ is the optimal angle of the current water retaining mechanism, θ α is the initial angle of the water retaining mechanism, P is the current spray water pressure of the cooling mechanism, P α is the initial water pressure of the cooling mechanism, R is the preset range coefficient, and exp is the natural exponential function.

[0083] In this embodiment, the angle of the water retaining mechanism is the acute angle formed by the baffle plate 31 and the saw blade 22. The angle of the water retaining mechanism is controlled by the extension and retraction of the telescopic block 34, and the angle of the water retaining mechanism is set by the spraying water pressure of the cooling mechanism. The greater the water pressure, the greater the corresponding angle of the water retaining mechanism, which is conducive to the baffle plate 31 to capture the splashing coolant, and prevent the coolant from splashing again after splashing onto the baffle plate 31, causing the steel to be soaked black.

[0084] By applying the above technical scheme, the present invention includes a support platform 1; a sawing mechanism, including a drive seat 21 and a saw blade 22; a water retaining mechanism, which is covered on the upper part of the saw blade 22, and the water retaining mechanism is used to shield the saw blade 22; a cooling mechanism, which is arranged on the inner wall of the water retaining mechanism, and the cooling mechanism is used to spray and cool the saw blade 22; a recovery mechanism, which is arranged inside the support platform 1, and the recovery mechanism is used to recover the coolant of the cooling mechanism; a cooling control module, which is used to obtain the surface temperature of the saw blade 22, and determine the spraying water pressure of the cooling mechanism according to the surface temperature of the saw blade 22; a water retaining control module, which is used to obtain the spraying water pressure of the cooling mechanism, and control the angle of the water retaining mechanism according to the spraying water pressure of the cooling mechanism. It can cool the sawing structure while guiding the coolant to prevent the coolant from splashing on the black steel.

[0085] Through the description of the above implementation methods, those skilled in the art can clearly understand that the present invention can be implemented by hardware, or by software plus a necessary general hardware platform. Based on such an understanding, the technical solution of the present invention can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (which can be a CD-ROM, a USB flash drive, a mobile hard disk, etc.), including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each implementation scenario of the present invention.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
