Description

Technical Field

[0001] This utility model belongs to the field of CNC sawing technology, specifically relating to a chip removal device for CNC sawing. Background Technology

[0002] A CNC band saw is a machine tool that uses circular saw blades, band saws, or saw strips as cutting tools to cut round, square, pipe, and profile metal materials. The CNC band saw is driven by a drive wheel and a driven wheel, and the cutting direction of the saw blade is controlled by a guide rail control frame. The band saw blade is straightened by adjusting the self-rotating bearing, and the sawdust is removed by a scraper.

[0003] Patent CN222492407U discloses "a chip removal device for a CNC sawing machine, belonging to the field of CNC sawing technology, including a sawing machine body and a base, wherein the base is fixedly installed at the bottom of the sawing machine body; by activating the drive component, the drive component can drive two sweeping rods to move towards or away from each other. Under the action of the spring, the bottom of the sweeping rods contacts the two side walls of the chip removal hole, thereby cleaning the side walls and facilitating the falling of chips for collection. This can clean up metal chips in a timely manner, avoiding vibration or displacement of the saw blade due to the accumulation of metal chips during the cutting process. It can reduce the time and labor costs of manual cleaning, and also reduce the safety risks that operators may face when cleaning metal chips."

[0004] Although the existing chip removal holes can collect naturally falling metal chips, a large number of small metal chips are also generated during the sawing process. The chip removal equipment cannot collect these small metal chips, which are easily dispersed into the air and pollute the surrounding air. Air containing a large amount of metal chips can affect human health if inhaled or enters the eyes, and there are areas for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a chip removal device for CNC sawing machines in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A chip removal device for a CNC sawing machine includes a sawing machine worktable, a chip removal mechanism installed on the top of the sawing machine worktable, and a suction and filtration mechanism installed inside the sawing machine worktable. The chip removal mechanism includes a support plate fixedly installed on the top of the sawing machine worktable and a plurality of chip removal grooves opened in the support plate. The suction and filtration mechanism includes a suction fan fixedly installed on one side of the bottom of the sawing machine worktable and a filter screen inclinedly installed on the bottom inner side of the sawing machine worktable.

[0008] The sawing machine workbench is equipped with a cleaning mechanism, which includes a movable plate that is movably installed inside the sawing machine workbench, a counterweight plate that is slidably installed at the bottom of the movable plate and abuts against the bottom of the inner wall of the sawing machine workbench, and a dredging mechanism installed on one side of the counterweight plate for clearing the filter screen.

[0009] As a further optimization of this utility model, a door is provided on one side of the sawing table, and the filter screen, movable plate and counterweight plate are all fitted together between the inner wall of the sawing table and one side of the door.

[0010] As a further optimization of this utility model, the unblocking mechanism includes an inclined plate fixedly disposed at the bottom of one end of the counterweight plate, and a plurality of first bristles fixedly disposed at the bottom end of the inclined plate and inserted into the mesh of the filter screen.

[0011] As a further optimization of this utility model, a motor is fixedly installed on the outside of the sawing table, and a threaded rod rotatably connected to the output end of the motor is fixedly provided in the sawing table. The top of the movable plate is threaded onto the outer wall of the threaded rod, and a limiting light rod penetrating the top of the movable plate is fixed between the inner walls of the sawing table.

[0012] As a further optimization of this utility model, U-shaped rings are fixedly provided on both sides of the top of the movable plate, and a second brush bristle for cleaning the threaded rod after rotation is fixedly provided on the inner side of the U-shaped ring.

[0013] As a further optimization of this utility model, a sponge board is fixedly provided at the top of the movable plate, and a discharge baffle is detachably installed in the discharge port at the bottom of the saw table away from the filter screen.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The chip removal groove on the top of the support plate can discharge metal chips into the sawing table for chip removal. After the suction fan is running, in conjunction with the filter screen, smaller metal chips can be sucked in and collected into the sawing table, making it less likely for the small chips generated during processing to drift into the outside air and pollute the air. After the cleaning mechanism is moved, the collected metal chips can be compressed by the counterweight plate and other components to reduce the space occupied, and the filter screen can also be unblocked, which is convenient and practical.

[0016] 2. By moving the counterweight plate at the bottom of the movable plate, the counterweight plate can be raised and lowered adaptively, which facilitates the counterweight plate to push and compress the metal debris on the filter screen and the top of the saw table. When the discharge baffle is removed, the compressed metal debris can be discharged under the push of the counterweight plate, which is convenient and quick. The second bristles inside the U-shaped ring can brush away the metal debris attached to the outside of the threaded rod when the movable plate moves, so that the metal debris is not easy to get stuck at the connection between the movable plate and the threaded rod, thus ensuring the normal use of the equipment.

Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example

[0024] like Figure 1-4 As shown, a chip removal device for a CNC sawing machine includes a sawing worktable 1, a chip removal mechanism, and a suction and filtration mechanism. The chip removal mechanism is installed on the top of the sawing worktable 1 and includes a support plate 2 fixedly installed on the top of the sawing worktable 1 and a plurality of chip removal grooves 21 opened in the support plate 2. The sawing worktable 1 is the worktable of an existing CNC sawing machine. The sawing mechanism of the existing CNC sawing machine can be installed on the top of the support plate 2. The metal chips generated during processing can easily fall into the sawing worktable 1 through the chip removal grooves 21. The operator can also push some chips remaining on the top of the support plate 2 into the sawing worktable 1 through the chip removal grooves 21 for collection, thereby removing chips.

[0025] like Figure 1-2As shown, the suction and filtration mechanism is installed inside the sawing machine worktable 1. The suction and filtration mechanism includes a suction fan 3 fixedly installed on one side of the bottom of the sawing machine worktable 1, and a filter screen 31 inclinedly installed on the bottom inner side of the sawing machine worktable 1. The filter screen 31 is located on one side of the suction fan 3. The suction fan 3 can be a negative pressure fan or other fan with suction effect. After the suction fan 3 is running, it will suck the small metal debris generated during the processing of the top of the support plate 2 into the sawing machine worktable 1. Under the filtration of the filter screen 31, the small metal debris can be retained in the sawing machine worktable 1 and collected, so that the small debris generated during processing is not easily dispersed into the outside air and pollute the air.

[0026] like Figure 2-3 As shown, the saw table 1 is equipped with a cleaning mechanism, which includes a movable plate 4 movably disposed inside the saw table 1, a counterweight plate 41 slidably disposed at the bottom end of the movable plate 4 and in cooperation with the bottom of the inner wall of the saw table 1, and a drainage mechanism disposed on one side of the counterweight plate 41 for clearing the filter screen 31. The counterweight plate 41 can slide at the bottom of the movable plate 4, so that the counterweight plate 41 will naturally hang down under its own weight. After the counterweight plate 4 moves with the movable plate 4, it can push and gather the metal debris that falls to the bottom of the inner wall of the saw table 1 and the top of the filter screen 31.

[0027] like Figure 2-3 As shown, the unblocking mechanism includes an inclined plate 42 fixedly disposed at the bottom of one end of the counterweight plate 41, and a plurality of first bristles 43 fixedly disposed at the bottom end of the inclined plate 42 and inserted into the mesh of the filter screen 31. The inclined plate 42 can connect the counterweight plate 41 and the first bristles 43. After the first bristles 43 move with the counterweight plate 41, they can unblock the filter screen 31.

[0028] like Figure 2-3 As shown, a door 11 is rotatably provided on one side of the sawing table 1. The operator can open the door 11 to inspect and maintain the internal components of the sawing table 1. The filter screen 31, the movable plate 4, and the counterweight plate 41 are all fitted together between the inner wall of the sawing table 1 and one side of the door 11, so that the gap between the filter screen 31, the movable plate 4, and the counterweight plate 41 and the sawing table 1 and the door 11 is small.

[0029] like Figure 2 and Figure 4 As shown, a motor 5 is fixedly installed on the outside of the sawing table 1. A threaded rod 51 is fixedly connected to the output end of the motor 5 and rotated inside the sawing table 1. The top of the movable plate 4 is threaded onto the outer wall of the threaded rod 51. A limiting light rod 52 that passes through the top of the movable plate 4 is fixed between the inner walls of the sawing table 1. The motor 5 can rotate forward and backward. This is a public technology and will not be described in detail here.

[0030] The limiting rod 52 can limit the through movable plate 4, so that the movable plate 4 can only move laterally and cannot rotate. After the motor 5 runs, it will drive the threaded rod 51 to rotate. With the limiting of the limiting rod 52, the movable plate 4 and the counterweight plate 41 and other components can move.

[0031] like Figure 2 and Figure 4 As shown, U-shaped rings 53 are fixed on both sides of the top of the movable plate 4. A second brush bristle 54 for cleaning the rotated threaded rod 51 is fixed on the inner side of the U-shaped ring 53. The threaded rod 51 is located inside the U-shaped ring 53. The second brush bristle 54 inside the U-shaped ring 53 can brush away the metal debris attached to the outside of the rotating threaded rod 51 when the movable plate 4 moves, so that the metal debris is not easily stuck in the connection between the movable plate 4 and the threaded rod 51, thus ensuring the normal use of the equipment.

[0032] like Figure 2 As shown, a sponge board 44 is fixedly installed at the top of the movable plate 4. A discharge baffle 12 is detachably installed in the discharge port at the bottom of the saw table 1 away from the filter screen 31. The sponge board 44 is fitted between the inner wall of the saw table 1 and one side of the door 11. The sponge board 44 can partially close the top of the movable plate 4 when the counterweight plate 41 and other components compress metal chips, thereby restricting the position of the metal chips and facilitating compression. The discharge baffle 12 can be detachably installed on the outer wall of the saw table 1 by means of a latch or other means. The discharge baffle 12 can close the discharge port of the saw table 1.

[0033] It should be noted that before using this CNC sawing chip removal equipment, the control motor 5 is rotated in both directions. After the motor 5 runs, it will drive the threaded rod 51 to rotate. With the limit of the limit rod 52, it can drive the movable plate 4 and the counterweight plate 41 to move. The counterweight plate 41 can be adaptively raised and lowered at the bottom of the movable plate 4, so that the counterweight plate 41 can be moved to the top of the inclined filter screen 31.

[0034] When in use, the metal chips generated by the CNC sawing machine are easily dropped into the sawing machine worktable 1 through the chip discharge groove 21. At the same time, the suction fan 3 is turned on. After the suction fan 3 is running, it will suck the smaller metal chips generated during the processing of the top of the support plate 2 into the sawing machine worktable 1. Under the filtration of the filter screen 31, the smaller metal chips can be kept in the sawing machine worktable 1 and collected, so that the smaller metal chips generated during processing are not easily scattered into the outside air and pollute the air.

[0035] When it is necessary to clean the metal debris inside the sawing table 1, turn off the suction fan 3 and control the motor 5 to move the movable plate 4, counterweight plate 41 and unblocking mechanism toward the discharge baffle 12. At this time, after the movable plate 4 and counterweight plate 41 move, they can push and gather the metal debris that has fallen to the bottom of the inner wall of the sawing table 1 and the top of the filter screen 31. After the first brush 43 in the unblocking mechanism moves, it can unblock the filter screen 31. As the counterweight plate 41 and other components continue to move, they can press the pushed and gathered metal debris against the inner wall of the sawing table 1, thereby compressing the metal debris and reducing the space occupied.

[0036] After the metal scraps are compressed, the discharge baffle 12 can be removed. Under the push of components such as the counterweight plate 41, the compressed metal scraps can be discharged through the discharge port of the saw table 1 to remove the compressed scraps.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
