[0015] The second aspect of the present invention provides a method for using a cutting machine tool with a fire extinguishing device, including two methods: a signal-activated fire extinguishing operation and a manual-activated fire extinguishing operation.

[0016] According to the method for using a cutting machine tool with a fire extinguishing device provided by an embodiment of the second aspect of the present invention, the signal-activated fire extinguishing operation comprises the following steps:

[0017] Step 1: The flame detector detects a fire source in the cavity inside the chassis, and the flame detector sends a signal to the CNC system;

[0018] Step 2: The CNC system receives the signal from the flame detector and drives the mounting frame to terminate the cutting operation and move the worktable back to the initial position;

[0019] Step 3: The mobile workbench moves back and forth in the horizontal direction, and the driving part is started at the same time. The driving part drives the support plate to move until the support plate is no longer in contact with the baffle plate, so that the support plate clears the baffle plate. The baffle plate rotates to open the sand outlet, and the fire sand falls from the sand outlet, falls through the through groove to the sand hopper, and falls along the sand hopper to the mobile workbench area.

[0020] According to the method for using a cutting machine tool with a fire extinguishing device provided by an embodiment of the second aspect of the present invention, manually starting the fire extinguishing operation includes the following steps:

[0022] Step 2: Press the manual switch, the drive part starts, and the drive part drives the support plate to move until the support plate is no longer in contact with the baffle, so that the support plate clears the baffle, the baffle rotates, opens the sand outlet, and the fire sand falls from the sand outlet, through the through slot to the sand hopper, and then falls along the sand hopper to the mobile workbench area.

[0023] The cutting machine tool with a fire extinguishing device and the use method thereof provided by the embodiment of the present invention have at least the following beneficial effects:

[0024] The flame detector is connected to the CNC system signal. When the flame detector detects a fire source in the chassis, it sends a signal to the CNC system, so that the warning light of the cutting machine can sound an alarm to remind the relevant staff. At this time, the relevant staff can quickly prepare for fire extinguishing operations and evacuate people when they hear the alarm. At the same time, the flame detector sends a signal to the CNC system to drive the mounting frame to terminate the cutting operation, move the workbench back to the initial position, and drive the support plate to move and open the baffle, so that the sand outlet can be quickly opened, allowing the fire sand to automatically flow out to cover the fire source, greatly shortening the fire extinguishing response time and effectively improving the fire extinguishing efficiency.

[0025] Compared with the traditional manual fire extinguishing method, the cutting machine tool with fire extinguishing device does not require personnel to directly contact the fire source, which reduces the safety risk of personnel during the fire extinguishing process and improves the safety of on-site operations. The fire extinguishing device has a reasonable structural design, which not only takes up little space, but also facilitates daily maintenance.

[0026] Compared with the complex pipeline fire extinguishing system, the cutting machine tool with fire extinguishing device is low-cost and easy to install. When installing the fire extinguishing device, there is no need to make major changes to the structure of the machine tool. At the same time, the sand discharge component in the fire extinguishing device is detachably connected to the chassis, which is convenient for the staff to monitor the remaining fire sand in the box. The fire sand can be added or replaced in the box in time for emergency needs, which reduces the company's investment and maintenance costs and is convenient and quick to use.

[0027] The cutting machine tool with a fire extinguishing device provided in the embodiment of the present invention has two methods of signal-activated fire extinguishing operation and manual-activated fire extinguishing operation. It can prevent accidents before they occur during use, effectively reducing the risk of fire during active metal processing and improving the overall safety and production stability of the machine tool. The rapid extinguishing of fire means a reduction in production interruption time, which helps enterprises maintain an efficient production rhythm and avoid long-term downtime losses caused by fire.

[0047] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0048] refer to Figures 1 to 4 According to the first aspect of the present invention, a cutting machine tool with a fire extinguishing device is provided, which includes a base 300, a movable workbench 310 and a mounting frame 240 arranged on the base 300, and also includes a chassis 200 and a fire extinguishing device 100.

[0049] The chassis 200 is arranged on the base 300, and a cavity is formed inside the chassis 200. The base 300 and the mounting frame 240 both extend into the cavity, and a through slot 201 is opened on the chassis 200. The fire extinguishing device 100 is detachably arranged on the chassis 200, and the fire extinguishing device 100 partially extends into the cavity through the through slot 201.

[0050] refer to Figures 6 to 8 The fire extinguishing device 100 includes a sand discharge assembly 110, a flame detector 130 and a numerical control system. The sand discharge assembly 110 includes a box 111 and an opening and closing mechanism 140. The box 111 is used to store fire sand. The box 111 is detachably connected to the chassis 200. The box 111 is provided with a sand discharge port 113, which is connected to the through slot 201. The opening and closing mechanism 140 is arranged at the sand discharge port 113, and the opening and closing mechanism 140 can close and open the sand discharge port 113. The flame detector 130 is arranged in the cavity, and the flame detector 130 is connected to the numerical control system signal, and the numerical control system is electrically connected to the opening and closing mechanism 140.

[0051] It should be noted that the box 111 is used to store fire sand, and a sand outlet 113 is provided at the bottom of the box 111, and the fire sand can flow out from the sand outlet 113. The box 111 is detachably connected to the chassis 200. As an example, the box 111 is threadedly connected to the outside of the chassis 200. In other embodiments, the box 111 can be snap-connected to the chassis 200.

[0052] When the chassis 200 is stably fixed on the chassis 200, the lower sand port 113 is aligned with the through slot 201. At this time, the opening and closing mechanism 140 is located in the through slot 201. When the opening and closing mechanism 140 opens the lower sand port 113, the fire-fighting sand in the box body 111 flows out from the lower sand port 113 and can enter the cavity inside the chassis 200 through the through slot 201 to extinguish the flame generated by the spontaneous combustion of active metal debris in the machine tool.

[0053] refer to Figure 4 and Fig.10The flame detector 130 is arranged on one side of the machine tool. Specifically, the flame detector 130 is arranged at a corner of the machine tool and is threadedly connected to the machine tool. The detection range of the flame detector 130 can cover the entire movable workbench 310. When the workpiece is cut on the movable workbench 310, if spontaneous combustion occurs, the flame detector 130 can detect it in the first time and send a signal to the numerical control system (not shown in the figure) at the same time. The numerical control system controls the opening and closing mechanism 140 to open the sand outlet 113, and the fire sand flows out from the sand outlet 113 and can enter the cavity inside the chassis 200 through the through groove 201. The numerical control system can install the frame 240 to stop processing the workpiece and control the movable workbench 310 to return to its original position. Then the movable workbench 310 reciprocates along the length direction of the chassis 200 to increase the coverage area of ​​the movable workbench 310 when the fire sand falls, thereby achieving the purpose of efficient fire extinguishing.

[0054] Among them, the working principle of the flame detector 130 is similar to that of the smoke alarm, and the flame detector 130 is an existing technology well known to the personnel in this field, and no changes are made in the present invention, so its function and working principle are not repeated in the present invention.

[0055] refer to Figure 6 As an additional embodiment, a sand storage groove 112 is provided on the box body 111, and the sand storage groove 112 is connected with the sand outlet 113, and the cross section of the sand storage groove 112 is a trapezoidal structure, and the length of the lower bottom side is smaller than the upper bottom, and the wall surface of the sand storage groove 112 forms an inclined slope, so that when the sand outlet 113 is opened, the firefighting sand in the sand storage groove 112 quickly slides down under the action of gravity and flows out of the sand outlet 113, so that the firefighting sand will not be blocked in the sand storage groove 112. A cover plate 114 is provided at the top of the box body 111, and the cover plate 114 is used to close the sand storage groove 112, which is conducive to extending the storage time of the firefighting sand and keeping the firefighting sand in the sand storage groove 112 dry, and the cover plate 114 is detachably connected to the box body 111. As an example, the cover 114 is threadedly connected to the box body 111. In some other embodiments, the cover 114 is slidably matched with the box body 111 so that the cover 114 can close or open the sand storage tank 112, making it convenient for staff to add or replace fire sand in the sand storage tank 112.

[0056] refer to Figures 7 to 9 According to the cutting machine tool with a fire extinguishing device provided by the embodiment of the first aspect of the present invention, the opening and closing mechanism 140 includes a baffle 141 and a support plate 143. The baffle 141 is rotatably arranged on the box body 111, and the baffle 141 can close or open the lower sand port 113. The support plate 143 is slidably arranged on the box body 111 and is located at the bottom of the baffle 141. The support plate 143 can support or suspend the baffle 141 to fix or rotate the baffle 141.

[0057] It should be understood that the support plate 143 is slidably disposed on the box body 111 and is located at the bottom of the baffle 141. When the support plate 143 is fixed to the bottom of the baffle 141 and contacts the baffle 141, the support plate 143 provides supporting force for the baffle 141, so that the baffle 141 is fixed. At this time, the baffle 141 can close the lower sand outlet 113. When the support plate 143 slides to be completely separated from the baffle 141, the baffle 141 loses its supporting force and rotates under the action of gravity, losing the closing effect on the lower sand outlet 113, so that the lower sand outlet 113 opens, and the fire sand falls from the lower sand outlet 113.

[0058] Specifically, the support plate 143 can slide back and forth along the length direction of the box body 111, and a hinge 210 is provided on the box body 111. The hinge 210 is connected to one end of the baffle 141 so that the baffle 141 can rotate. At the same time, the baffle 141 is located on one side of the sand outlet 113. When the baffle 141 is in contact with the box body 111, the baffle 141 can close the sand outlet 113 so that the fire sand can be stored in the sand storage tank 112. When the support plate 143 slides to be separated from the baffle 141, the baffle 141 rotates to open the sand outlet 113.

[0059] As an additional embodiment, a plurality of abutment blocks 142 are arranged at equal intervals on the side of the baffle 141 opposite to the hinge 210, the abutment blocks 142 are integrally formed with the baffle 141, a plurality of avoidance openings 144 are opened at equal intervals on the support plate 143, the number of the abutment blocks 142 is equal to the number of the avoidance openings 144, and the shape of the avoidance openings 144 is adapted to the shape of the abutment blocks 142 so that the abutment blocks 142 can extend into the avoidance openings 144.

[0060] When the baffle 141 needs to close the lower sand opening 113, the avoidance opening 144 on the support plate 143 is staggered with the resistance block 142, so that the resistance block 142 and the support plate 143 are in contact, and the support plate 143 is arranged at the bottom of the baffle 141. At this time, the support plate 143 has a supporting force on the baffle 141, so that the baffle 141 is fixed to close the lower sand opening 113.

[0061] When the sand outlet 113 needs to be opened, the support plate 143 slides to the avoidance opening 144 and corresponds to the resistance block 142 one by one. At this time, the support plate 143 and the baffle 141 are not in contact, the baffle 141 loses its supporting force, and rotates under the action of gravity, the sand outlet 113 opens, and the fire sand flows out.

[0062] refer to Figure 8 and Fig. 9In order to extend the service life of the support plate 143 and make the support plate 143 slide more smoothly, the opening and closing mechanism 140 in this embodiment also includes a first wear-resistant strip 146, a second wear-resistant strip 147 and a fixed frame 148. The fixed frame 148 is connected to the box body 111 and is located on one side of the lower sand port 113. The fixed frame 148 is provided with a mounting groove 1481, and the mounting groove 1481 penetrates the fixed frame 148. The first wear-resistant strip 146 and the second wear-resistant strip 147 are arranged in the mounting groove 1481, and the slide plate is located between the first wear-resistant strip 146 and the second wear-resistant strip 147. Due to the limiting effect of the first wear-resistant strip 146 and the second wear-resistant strip 147, the support plate 143 can keep sliding in the horizontal direction under the drive of the driving member 145. The fixed frame 148 is threadedly connected to the box body 111, and the first wear-resistant strip 146 and the second wear-resistant strip 147 are fixed in the mounting groove 1481, so that the first wear-resistant strip 146 and the second wear-resistant strip 147 have a reliable fixing effect. When the support plate 143 slides, the support plate 143 can slide smoothly, and the support plate 143 will not cause wear to other parts. When the first wear-resistant strip 146 and the second wear-resistant strip 147 need to be replaced, it is only necessary to remove the mounting frame, which is convenient for the staff to carry out subsequent maintenance and replacement work.

[0063] Furthermore, in order to adapt to the support plate 143, a plurality of first avoidance grooves 1461 are provided at equal intervals on the first wear-resistant strip 146, a plurality of second avoidance grooves 1471 are provided at equal intervals on the second wear-resistant strip 147, and a plurality of third avoidance grooves 1482 are provided at equal intervals on the mounting frame. The first avoidance groove 1461 penetrates the first wear-resistant strip 146, the second avoidance groove 1471 penetrates the second wear-resistant strip 147, and the third avoidance groove 1482 penetrates the mounting frame, and the first avoidance groove The shapes of the first avoidance groove 1461, the second avoidance groove 1471 and the third avoidance groove 1482 are the same, and the first avoidance groove 1461, the second avoidance groove 1471 and the third avoidance groove 1482 are aligned. When the baffle 141 rotates, the resistance block 142 can pass through the first avoidance groove 1461, the second avoidance groove 1471 and the third avoidance groove 1482, so that the first wear-resistant strip 146, the second wear-resistant strip 147 and the fixed frame 148 will not block the rotation of the baffle 141.

[0064] According to the cutting machine tool with a fire extinguishing device provided in the embodiment of the first aspect of the present invention, the opening and closing mechanism 140 also includes a driving member 145, the driving member 145 is electrically connected to the numerical control system, the driving member 145 is connected to the support plate 143, and the driving member 145 can drive the support plate 143 to move so that the support plate 143 supports or suspends the baffle 141.

[0065] refer to Figure 7It should be understood that, as an example, the driving member 145 includes a cylinder and a piston rod, the cylinder is threadedly connected to the box body 111, and the piston rod is connected to the support plate 143. When the piston rod is shortened, it drives the support plate 143 to slide horizontally along the length direction of the box body 111 until the avoidance opening 144 is aligned with the abutment block 142, and the baffle 141 rotates, thereby opening the sand outlet 113. By using the cylinder and the piston rod as the driving member 145, the short-stroke cylinder can drive the support plate 143 to slide, which is convenient for installation and reduces costs, and will not hinder the staff from performing other operations. The solenoid valve of the cylinder is connected to the numerical control system. When the numerical control system receives the signal from the flame detector 130, the switch of the solenoid valve is turned on so that the cylinder drives the piston rod to drive the support plate 143 to slide, so that the support plate 143 is separated from the baffle 141, and the fire sand falls from the sand outlet 113.

[0066] refer to Figure 4 and Figure 5 According to the cutting machine tool with a fire extinguishing device provided by the first embodiment of the present invention, the sand discharge assembly 110 further includes a sand drop hopper 120, which is arranged in the cavity and located at the position of the through slot 201. The position of the sand drop hopper 120 is adapted to the through slot 201, so that when the sand discharge port 113 is opened, the fire fighting sand flows from the through slot 201 into the machine box 200, and then flows along the wall of the sand drop hopper 120 to the movable workbench 310 to cover the fire source.

[0067] According to the cutting machine tool with a fire extinguishing device provided in the embodiment of the first aspect of the present invention, the sand falling bucket 120 includes a first sand falling plate 121, a second sand falling plate 122 and a sand retaining plate 123, the first sand falling plate 121 is vertically fixed to the chassis 200, the second sand falling plate 122 is connected to the first sand falling plate 121, and the angle formed between the first sand falling plate 121 and the second sand falling plate 122 is an obtuse angle, and sand retaining plates 123 are arranged on both sides of the first sand falling plate 121 and the second sand falling plate 122.

[0068] It should be noted that the first sand falling plate 121 and the second sand falling plate 122 are spliced ​​together, and the second sand falling plate 122 is inclined toward the direction of the movable workbench 310. The angle formed between the first sand falling plate 121 and the second sand falling plate 122 is an obtuse angle. When the firefighting sand falls to the second sand falling plate 122, the second sand falling plate 122 can guide the flow direction of the firefighting sand, and the sand retaining plate 123 can prevent the firefighting sand from sliding toward the two ends of the first sand falling plate 121 and the second sand falling plate 122, thereby increasing the coverage area of ​​the firefighting sand and having a buffering effect on the falling of the firefighting sand, so that the firefighting sand can effectively extinguish the fire source.

[0069] refer to Figure 3According to the cutting machine tool with a fire extinguishing device provided by the first aspect of the embodiment of the present invention, the sand removal assembly 110 includes at least two groups, which are symmetrically arranged on the chassis 200, and there are at least two through grooves 201, and the lower sand port 113 corresponds to the through grooves 201 one by one.

[0070] As an example, two groups of sand removal components 110 are provided, which are symmetrically arranged on the top of the chassis 200. Correspondingly, two through slots 201 are opened, and a lower sand opening 113 corresponds to a through slot 201. The symmetrically arranged sand removal components 110 will be able to better adapt to the length of the mobile workbench 310. When extinguishing a fire, the coverage area of ​​the fire-fighting sand can be increased, and more fire-fighting sand can be stored to improve the efficiency of fire-fighting.

[0071] refer to Figure 1 ,to Figure 4 The cutting machine tool with a fire extinguishing device provided in accordance with the first aspect of the embodiment of the present invention also includes a control console 220 and a manual switch 230. The control console 220 is arranged in the chassis 200, and the control console 220 is electrically connected to the movable workbench 310, and the manual switch 230 is electrically connected to the driving member 145.

[0072] It should be noted that the staff can operate the control console 220 to control the mounting frame 240, thereby operating the machine tool to process the workpiece, terminate the processing of the workpiece, and control the movement of the movable workbench 310, and the manual switch 230 is arranged on the control console 220. The manual switch 230 is electrically connected to the driving member 145. When the manual switch 230 is pressed, the driving member 145 is turned on, and the support plate 143 is driven to slide to disengage from the baffle 141, so that the lower sand port 113 is opened, and the fire extinguishing operation is directly performed.

[0073] The second aspect of the present invention provides a method for using a cutting machine tool with a fire extinguishing device, including two methods: a signal-activated fire extinguishing operation and a manual-activated fire extinguishing operation.

[0074] According to the method for using a cutting machine tool with a fire extinguishing device provided by an embodiment of the second aspect of the present invention, the signal-activated fire extinguishing operation comprises the following steps:

[0075] Step 1: As a preparatory work, the staff needs to add a sufficient amount of fire sand to the sand storage tank 112, and fix the box body 111 at a suitable position on the top surface of the machine tool so that the sand outlet 113 corresponds to the through groove 201. The flame detector 130 detects that there is a fire source in the cavity inside the box 200, and the flame detector 130 sends a signal;

[0076] Step 2: The numerical control system receives the signal sent by the flame detector 130, and drives the mounting frame 240 to terminate the cutting operation, and moves the workbench 310 back to the initial position;

[0077] Step 3: The mobile workbench 310 reciprocates in the horizontal direction, and at the same time the driving member 145 is started, and the driving member 145 drives the support plate 143 to move until the support plate 143 is no longer in contact with the baffle 141, so that the support plate 143 clears the baffle 141, and the baffle 141 rotates to open the sand outlet 113, and the fire-fighting sand falls from the sand outlet 113, falls into the sand hopper 120 through the through groove 201, and falls along the sand hopper 120 to the mobile workbench 310 area.

[0078] Since the cutting process is located on the mobile workbench 310, when extinguishing a fire, the mobile workbench 310 reciprocates in the horizontal direction. At the same time, the firefighting sand falls onto the mobile workbench 310 along the sand drop hopper 120, which can increase the coverage area of ​​the firefighting sand and improve the fire extinguishing efficiency.

[0079] According to the method for using a cutting machine tool with a fire extinguishing device provided by an embodiment of the second aspect of the present invention, manually starting the fire extinguishing operation includes the following steps:

[0080] Step 1: As a preparatory work, the staff needs to add a sufficient amount of fire sand to the sand storage tank 112, and fix the box body 111 at an appropriate position on the top surface of the machine tool so that the sand outlet 113 corresponds to the through groove 201. If the staff finds a fire source in the box 200 in advance, they will actively press the manual switch 230 and restore the movable workbench 310 to the initial position through the control console 220;

[0081] Step 2: The driving member 145 is started, and the driving member 145 drives the support plate 143 to move until the support plate 143 is no longer in contact with the baffle 141, so that the support plate 143 clears the baffle 141, and the baffle 141 rotates to open the sand outlet 113, and the firefighting sand falls from the sand outlet 113, passes through the through groove 201 and falls into the sand hopper 120, and falls along the sand hopper 120 to the movable workbench 310 area.

[0082] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
