[0034] See also Figure 1-Figure 7 As shown, the present invention provides a CNC metal processing machine tool, including a base plate 1, a conveyor belt 2 and an outgoing belt are respectively arranged on both sides of the top surface of the base plate 1, a processing table 4 for positioning and entering a metal workpiece is arranged at the end of the conveyor belt 2, the processing table 4 is arranged in a U-shaped structure, and an automatically reset push plate 24 is arranged at the edge of the bottom surface of the inner cavity of the processing table 4, an abutment groove 25 is arranged on the end surface of the push plate 24, and an elastic member is installed at the bottom end of the push plate 24, a loading and pushing assembly is installed above the conveyor belt 2 and on one side close to the processing table 4, and the loading and pushing assembly includes a lifting cylinder 5 arranged on both sides of the conveyor belt 2, and the pushing end of the lifting cylinder 5 is connected to a hollow frame 6, and both ends of the hollow frame 6 are connected and provided with a protrusion The protruding portion 10 is provided with a push plate 8 pushed by a segmented stroke cylinder inside the hollow frame 6, and a push block 9 pushed by a material pushing cylinder is installed inside the protruding portion 10; a strip groove 7 for the push block 9 to enter is provided through the surface of the processing table 4, and the inner cavity end of the strip groove 7 is communicated with the inner wall surface of the processing table 4, and the end surface of the push block 9 is provided with an inclined surface abutting with the abutting groove 25, and a fitting surface contacting with the inner cavity end surface of the strip groove 7 is provided adjacent to one side of the inclined surface. The metal workpiece is a metal sheet. During the initial operation, the processing table 4 is located between the conveyor belt 2 and the outgoing belt, and the hollow frame 6 therein is lifted upward by the push of the lifting cylinder 5, so that the metal workpiece is conveniently introduced from the conveyor belt 2 into the interior of the processing table 4. After that, refer to Figure 1 and Figure 2 As shown, the lifting cylinder 5 pushes the hollow frame 6 to move down, and the segmented stroke cylinder pushes the push plate 8 at one time, and the metal workpiece is pushed into the interior of the processing table 4 by means of the push plate 8 until the end face of the metal workpiece contacts the surface of the push plate 24, and the push plate 24 blocks and limits the metal workpiece to avoid the deviation of the loading position, without the need for correction and alignment, and shortens the time. Then the push plate 8 is reset, but the height of the hollow frame 6 remains unchanged, and then the height of the processing table 4 rises, which is convenient for cutting the metal workpiece. After the cutting is completed, the metal workpiece is reset and moved down to the initial position with the processing table 4, and the push cylinder pushes the push block 9 into the strip groove 7, see Figure 5 and Figure 6As shown, in this state, the inclined surface of the push block 9 first contacts the abutment groove 25, and under the thrust, the push plate 24 presses the compressed elastic member until the push block 9 passes through the upper end surface of the push plate 24, and its fitting surface contacts the inner wall surface of the strip groove 7. At this time, the push plate 24 is downward, that is, it enters the bottom surface of the inner cavity of the processing table 4, and then through the secondary push of the segmented stroke cylinder, the metal workpiece is completely pushed away from the interior of the processing table 4, that is, it is moved to the transfer belt. At this time, the push plate 8 and the push block 9 are reset and retracted in turn, the push plate 24 extends upward, and then the lifting cylinder 5 lifts the hollow frame 6 again, realizing the automatic loading and unloading of the workpiece and improving the production efficiency.

[0035] See also Figure 5 and Figure 6 As shown, the bottom surface of the inner cavity of the processing table 4 and the lower end surface of the strip groove 7 are provided with a reset groove 36 that slidably cooperates with the push plate 24. The elastic member is installed inside the reset groove 36. The elastic member includes a compression spring 26. One end of the compression spring 26 is fixed to the lower end surface of the push plate 24, and the other end of the compression spring 26 is fixed to the bottom surface of the inner cavity of the reset groove 36. When the push block 9 enters the inner end portion of the strip groove 7, the inclined surface of the push block 9 contacts the reset groove 36, so that the push plate 24 slides in the reset groove 36. The compression spring 26 is squeezed during the sliding process, so that the compression spring 26 produces elastic deformation. When the push block 9 passes through the upper end surface of the push plate 24, the push plate 24 is hidden in the reset groove 36 at this time, that is, the push plate 24 releases the restriction on the side of the metal workpiece, which facilitates the metal workpiece to be pushed out.

[0036] See also Figure 2 As shown, a card plate 35 for blocking metal workpieces is installed on the lower surface of the hollow frame 6. The card plate 35 is adjacent to and does not contact the upper surface of the conveyor belt 2. When the hollow frame 6 moves downward by the lifting cylinder 5, the card plate 35 moves downward synchronously. The card plate 35 is located on the upper part of the conveyor belt 2 and is used to block the metal workpiece to prevent the next metal workpiece from entering.

[0037] See also Figure 1 and Figure 7As shown, transverse plates 27 are installed on both sides of the top surface of the processing table 4, and the bottom surface of the inner cavity of each transverse plate 27 is installed with a compression spring 28, one end of the compression spring 28 is fixedly connected to a buffer seat 29 sliding in the transverse plate 27, and a cleaning unit for wiping the surface of the metal workpiece is arranged inside the buffer seat 29; the cleaning unit includes a accommodating cavity arranged on the bottom surface of the buffer seat 29, and a transfer roller 31 and an adsorption roller 30 are rotatably installed inside the accommodating cavity, the transfer roller 31 is rollingly fitted with the adsorption roller 30, and a scraper 32 is fitted on the outer surface of the transfer roller 31, and a chip removal port 33 for impurities on the scraper 32 to fall into is arranged inside the buffer seat 29, and a chip removal box 34 connected to the chip removal port 33 is installed on the outer wall surface of the transverse plate 27. When the metal workpiece passes through a transverse plate 27, the buffer seat 29 is squeezed upward, that is, the buffer seat 29 moves in the transverse plate 27 and squeezes upward. The compression spring 28 makes the cleaning unit fit more closely with the metal workpiece to ensure the cleaning effect. The adsorption roller 30 rotates counterclockwise to roll and adsorb the upper surface of the metal workpiece, and then the transfer roller 31 rotates clockwise to adsorb the adsorbed metal impurities. Then, the scraper 32 rubs the transfer roller 31, and the scraped metal impurities enter the chip removal box 34 along the chip removal port 33 for centralized collection. When the processed metal workpiece is pushed out from the processing table 4, the cleaning unit in another cross plate 27 contacts the surface of the metal workpiece, that is, the adsorption roller 30 in the cleaning unit rotates clockwise, and the transfer roller 31 rotates counterclockwise to frictionally contact with the corresponding scraper 32 for cleaning again. The adsorption roller 30 and the transfer roller 31 are both magnetic, and the magnetism of the adsorption roller 30 is smaller than that of the transfer roller 31. It has the function of adsorbing metal powder and can transfer metal powder.

When the metal workpiece is loaded into the processing table 4, its side and the push-pull contact are locked. The plate 24 contacts. Initially, the position of the sliding seat 14 remains stationary. The pressing cylinder pushes the pressing plate 16 downward to fix the metal workpiece, which is convenient for cutting the metal workpiece. When processing different positions of the metal workpiece, the rotation of the bidirectional screw 12 drives the corresponding adjustment plate 13 and the sliding seat 14 to slide on the limit table 11. The sliding of the sliding seat 14 on the limit table 11 ensures the orientation and stability of the sliding, changes the horizontal position of the pressing plate 16 and the mounting plate 15, and fixes other positions of the metal workpiece to adapt to the cutting of metal workpieces at different positions, thereby improving applicability.

[0039] See also Figure 4 As shown, a stand 3 is installed on the rear side of the upper surface of the base plate 1, and a bidirectional screw rod 17 is rotatably installed on the surface of the stand 3.

A transverse frame 21 is slidably connected to the outside of the linear guide rail 20, and a guide groove 23 is arranged on the top surface of the transverse frame 21 along the end direction, and a cutting unit moved ... a cutting unit moved in different directions is sleeved on the other thread of the bidirectional screw rod 17, and a cutting unit moved in different directions is sleeved on the other thread of the bidirectional screw rod 17, and a cutting unit moved in different directions is sleeved on the other thread of the bidirectional screw rod 17, and a cutting unit moved in different directions is sleeved on the other thread of the bidirectional screw rod 17, and a cutting unit moved in different directions is sleeved on the other thread of the bidirectional screw rod 17, and a cutting unit moved in different directions is sleeved on the other thread The guide seat 22 is driven by the adjusting cylinder installed on the transverse frame 21, and the lower surface of the guide seat 22 is installed with a cutting tool for processing metal workpieces. When the metal workpiece is fixed on the processing table 4, the transmission seat 18 moves down and the height of the processing table 4 moves up through the rotation of the bidirectional screw 17. During the movement, the transverse frame 21 and the guide seat 22 on the transmission seat 18 change according to the processing position, that is, the transverse frame 21 slides horizontally under the sliding of the linear guide rail 20, and the guide seat 22 slides along the guide groove 23 under the push of the adjusting cylinder, so as to adapt to the cutting processing of metal workpieces in different positions.

[0040] When the present invention is in use, by setting a loading and pushing assembly, the lifting cylinder 5 first pushes the hollow frame 6 to move down in height, and then the segmented stroke cylinder pushes the push plate 8 once, and the push plate 8 is used to push the metal workpiece completely into the interior of the processing table 4 until the end face of the metal workpiece contacts the surface of the push plate 24, and the push plate 24 blocks and limits the metal workpiece to avoid the deviation of the loading position, without the need for correction and alignment, and shortens the time. After the cutting is completed, the metal workpiece moves down to the initial position with the processing table 4 reset, and the push block 9 enters the strip groove 7. The inclined surface first contacts the abutment groove 25, and under the thrust, the push plate 24 presses the compressed elastic member until the push block 9 passes through the upper end surface of the push plate 24, and its contact surface contacts the inner wall surface of the strip groove 7. At this time, the push plate 24 enters downward into the bottom surface of the inner cavity of the processing table 4, and through the secondary push of the segmented stroke cylinder, the metal workpiece is completely pushed away from the inside of the processing table 4, that is, moved to the conveyor belt. At this time, the push plate 8 and the push block 9 are reset and retracted in turn, and the push plate 24 extends upward, realizing the automatic loading and unloading of the workpiece, thereby improving the production efficiency.

[0041] By setting the transverse plate 27 and the cleaning unit, when the metal workpiece passes through one transverse plate 27, the buffer seat 29 is pressed upward, that is, the buffer seat 29 moves in the transverse plate 27 and presses the compression spring 28 upward, so that the cleaning unit and the metal workpiece are more closely fitted to ensure the cleaning effect. The upper surface of the metal workpiece is rolled and adsorbed by the counterclockwise rotation of the adsorption roller 30, and then the adsorbed impurities are adsorbed by the clockwise rotation of the transfer roller 31. Then, the scraper 32 is used to rub the transfer roller 31, and the scraped impurities are sent into the chip removal box 34 along the chip removal port 33 for centralized collection. When the processed metal workpiece is pushed out from the processing table 4, the surface of the metal workpiece is cleaned again by the cleaning unit in the other transverse plate 27. The cleaning is completed during the loading and pushing process, thereby improving the cleaning efficiency.

[0042] When the metal workpiece is pressed, the position of the sliding seat 14 remains stationary, and the pressing plate 16 is pushed down by pressing the cylinder to fix the metal workpiece, which is convenient for stable cutting of the metal workpiece.

The sliding orientation and stability of the sliding are guaranteed by the sliding of the sliding seat 14 on the limit platform 11, and the horizontal position of the pressing plate 16 and the mounting plate 15 is changed. By fixing other positions of the metal workpiece, it is adapted to the cutting of metal workpieces at different positions and improves applicability.
