Description

Technical Field

[0001] The utility model relates to a fire extinguishing device on a machine tool. Background Art

[0002] As we all know, magnesium alloys are widely used in certain special industrial scenarios due to their low density, light weight, good shock absorption performance and electrical and thermal conductivity, such as in related components of new energy vehicle battery packs.

[0003] Magnesium alloys have active chemical properties and a low ignition point. When processed by CNC machine tools, they easily generate heat and sparks, and even spontaneously combust. Water-based fire extinguishers cannot be used to extinguish fires. Existing technology usually involves manually covering the fire with materials such as dry sand. It is difficult for CNC machine tool automatic production lines to manually extinguish fires in the first place, so it is necessary to solve this problem. Utility Model Content

[0004] The utility model overcomes the deficiencies of the above technologies and provides a fire extinguishing device for a machine tool.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fire extinguishing device on a machine tool includes a machine bed body 1, the machine bed body 1 is provided with a processing table 2, and a container 3 for storing fire extinguishing covering material located above the processing table 2. The lower end of the container 3 is provided with an inclined downward discharge channel 31 for discharging the material obliquely toward the processing table 2. The inclined downward discharge channel 31 is provided with a blanking baffle 4 for blocking the downward discharge of the fire extinguishing covering material when it is swung upward into position and allowing the downward discharge of the fire extinguishing covering material when it is swung downward, and an action mechanism 5 for blocking / allowing the blanking baffle 4 to swing downward.

[0007] Preferably, the fire extinguishing covering material is dry sand.

[0008] Preferably, the action mechanism 5 includes a driver 51 arranged on the outside of the inclined downward discharge channel 31, a hinge 52 arranged on the outside of the inclined downward discharge channel 31 and driven by the driver 51 to swing back and forth, and a plurality of movable pins 53 driven by the hinge 52 for blocking the blanking baffle 4 from swinging downward when it moves to one end and for allowing the blanking baffle 4 to swing downward when it moves to the other end. Corresponding limiting passages 311 are provided between the inner and outer side walls of the inclined downward discharge channel 31 for limiting the passage of the plurality of movable pins 53, and the driver 51 adopts a push rod cylinder or a linear motor.

[0009] Preferably, the action mechanism 5 is provided with a manual control switch; or the machine tool body 1 is further provided with a flame sensor for detecting whether there is an open flame on the processing table 2, and a controller for controlling the action of the action mechanism 5 when the flame sensor is triggered.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The structure of this case is simple and easy to implement. The arrangement of the container above the side of the processing table does not hinder the processing work directly above the processing table. The arrangement of the downward inclined discharge channel makes it easier for the fire-extinguishing covering material in the container to tilt downward and fall onto the position on the processing table when a fire occurs on the processing table. The arrangement of the drop baffle and the action mechanism makes it easier to control whether the fire-extinguishing covering material in the container can be discharged downward. The arrangement is convenient and practical. During implementation, the user can pre-store the fire-extinguishing covering material in the container, which helps to avoid the time the user needs to spend looking for the fire-extinguishing covering material when a fire occurs.

[0012] 2. The action mechanism described in this case is easy to implement. When the driver drives the movable pin through the hinge to extend through the limit passage to the bottom of the blanking baffle, it blocks the movable pin from swinging downward. When the driver drives the movable pin to retract through the hinge, it does not prevent the movable pin from swinging downward. Under the action of gravity, the blanking baffle swings downward and the fire-extinguishing covering material is output downward. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0017] like Figures 1 to 3As shown, a fire extinguishing device on a machine tool comprises a machine tool body 1, which is provided with a machining table 2 and a container 3 for storing fire extinguishing covering material above the side of the machining table 2, the lower end of the container 3 is provided with an inclined downward discharge channel 31 for tilting to discharge material to the machining table 2, the inclined downward discharge channel 31 is provided with a material discharge baffle 4 for blocking downward output of the fire extinguishing covering material when swung upward to position and allowing downward output of the fire extinguishing covering material when swung downward, and a movement mechanism 5 for blocking / allowing downward swinging of the material discharge baffle 4.

[0018] As described above, the structure is simple and easy to implement, the container 3 is arranged above the side of the machining table 2, which facilitates the machining work above the machining table 2 without obstruction, the inclined downward discharge channel 31 is arranged, which facilitates the fire extinguishing covering material in the container 3 to tilt downward and fall to the position on the machining table 2 when the machining table 2 catches fire, the material discharge baffle 4 and the movement mechanism 5 are arranged, which facilitates the control of whether the fire extinguishing covering material in the container 3 can be output downward, and the arrangement is convenient and practical, in specific implementation, the user can pre-store fire extinguishing covering material in the container 3, which is beneficial to avoid the time for the user to find fire extinguishing covering material when catching fire.

[0019] As described above, when pre-storing fire extinguishing covering material, first swing the material discharge baffle 4 upward to position and block its downward swinging through the movement of the movement mechanism 5, and then pre-store fire extinguishing covering material in the container 3.

[0020] As described above, in specific implementation, the fire extinguishing covering material adopts dry sand, which is easy to obtain and not difficult to clean up subsequently.

[0021] As Figure 2 , Figure 3 As shown, as described above, in specific implementation, the movement mechanism 5 comprises a driver 51 arranged outside the inclined downward discharge channel 31, a hinge 52 arranged outside the inclined downward discharge channel 31 and swung back and forth by the driver 51, a plurality of movable pins 53 for blocking downward swinging of the material discharge baffle 4 when moved to one end and for allowing downward swinging of the material discharge baffle 4 when moved to the other end, a plurality of limiting passage openings 311 between the inner and outer side walls of the inclined downward discharge channel 31 for limiting passage of the plurality of movable pins 53, and the driver 51 adopts a push rod air cylinder or a linear motor.

[0022] As Figure 3 shown, the hinge 52 comprises a plurality of swing rods 521 connected in sequence, the middle segment of each swing rod 521 is rotationally connected outside the inclined downward discharge channel 31, and the back and forth swinging of the swing rod drives the movable pin 53 to move back and forth in the limiting passage opening 311.

[0023] As described above, the action mechanism 5 in this case is easy to implement. When the driver 51 drives the movable latch 53 through the hinge 52 to extend to the bottom of the blanking baffle 4 through the limiting passage 311, it blocks the movable latch 53 from swinging downward. When the driver 51 drives the movable latch 53 to retract through the hinge 52, it does not prevent the movable latch 53 from swinging downward. Under the action of gravity, the blanking baffle 4 swings downward and the fire-extinguishing covering material is output downward.
