After determining the appropriate position, the first motor is started to rotate the connecting plate in the direction of the longitudinal plate. When the connecting plate is at a vertical angle to the longitudinal plate, the clamping plate connected to the connecting plate can adjust the angle steel placed on the L-shaped plate. When the electric rubber wheel contacts the angle steel, its outer surface will be stressed, and then the first spring will be squeezed through the circular shaft.

After flipping, the angle steel will be inverted on the surface of the third crawler in a triangular state. Firstly, it can improve the stability during transportation, and secondly, it is convenient to stack multiple angle steels to save space. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 7 As shown, an embodiment of the present invention provides an angle steel cutting CNC machine tool, comprising a base plate 1, a feeding assembly 2 is fixedly installed on the top of the base plate 1, and a linkage punching and discharging mechanism, which comprises a clamping assembly 3, the clamping assembly 3 is fixedly installed on the right side of the feeding assembly 2, a punching assembly 4 is fixedly installed on the right side of the clamping assembly 3, and a discharging assembly 6 is fixedly installed on the right side of the punching assembly 4; The cutting assembly 5 is fixedly installed on the right side of the punching assembly 4. The cutting assembly 5 includes a column 51. Two second hydraulic rods 52 are fixedly connected to the inner side of the top of the column 51. The telescopic ends of the two second hydraulic rods 52 are fixedly connected to a cutter 53. A trapezoidal block 54 is fixedly installed on the right side of the cutter 53. Four telescopic rods 55 are fixedly connected to the left side of the trapezoidal block 54. The telescopic ends of the four telescopic rods 55 are all fixedly connected to the inner side of the top of the column 51. A load-bearing block 56 is fixedly connected to the bottom of the trapezoidal block 54. A through slot 57 is provided inside the block 54, and a rubber expansion block 59 is movably installed on the right side of the through slot 57. Two second springs 58 are fixedly installed on the right side of the trapezoidal block 54, and the right ends of the two second springs 58 are elastically connected to the load-bearing block 56; the column 51 is fixedly installed on the top of the bottom plate 1, and the inner side of the top of the column 51 is an inclined surface, and the left top of the trapezoidal block 54 is also an inclined surface. The slope of the inclined surface of the column 51 and the trapezoidal block 54 is the same, and the rubber expansion block 59 can move vertically in the through slot 57 through electric drive; The angle steel will first enter the through slot 57 of the trapezoidal block 54, but at this time the angle steel may not be at the center of the through slot 57. At this time, the rubber telescopic block 59 moves upward. The rubber telescopic block 59 presents a trapezoidal design with a narrow upper part and a wide lower part. During the continuous upward movement, the angle steel will be clamped in the through slot 57. At this time, the stroke of the two second hydraulic rods 52 is increased to drive the cutter 53 to cut the angle steel. The impact force generated during cutting can be slightly alleviated by the two second springs 58. When the two second hydraulic rods 52 are started, a sudden inertia will be generated, resulting in shaking. Therefore, the four telescopic rods 55 are adjusted to absorb the impact force, which solves the problem of lack of positioning of the angle steel after movement. In addition, the cutting tools used are mostly oblique cutting devices driven by hydraulic rods, which will generate vibrations during cutting and retracting, thereby causing the existing position of the angle steel to be offset. The feeding assembly 2 includes a base 21, which is fixedly mounted on the top of the bottom plate 1, an L-shaped plate 22 is fixedly mounted on the top of the base 21, a push block 23 is slidably mounted on the top of the L-shaped plate 22, a connecting rod 24 is fixedly connected to the right side of the push block 23, a first electric wheel 25 is fixedly connected to the other end of the connecting rod 24, a track 26 is movably sleeved on the outer edge of the first electric wheel 25, and the track 26 is fixedly mounted on the left side of the base 21; Place the angle steel in the L-shaped plate 22, start the clamping assembly 3, start the first electric wheel 25, and through the connecting rod 24, the push block 23 can also have a pushing effect on the angle steel on the surface of the L-shaped plate 22; Among them, the clamping assembly 3 includes two second electric wheels 31. Both of the two second electric wheels 31 are movably clamped in the track 26. A longitudinal plate 32 is fixedly installed at the top of the two second electric wheels 31.

The right ends of the two groups of first springs 38 are fixedly connected to the clamping plate 35. An electric rubber wheel 39 is sleeved on the outer edge of the two round shafts 37; The second electric wheel 31 moves in the track 26, driving the whole clamping assembly 3 to move. After determining the appropriate position, start the first motor 33, rotate the connecting plate 34 towards the direction where the longitudinal plate 32 is located. When the connecting plate 34 and the longitudinal plate 32 are at a right angle, the clamping plate 35 connected to the connecting plate 34 can play an adjusting role on the angle steel placed on the L-shaped plate 22. When the electric rubber wheel 39 contacts the angle steel, the outer surface of it will be stressed, and then the first spring 38 is squeezed through the round shaft 37. After the first spring 38 is stressed, it will return to its original position. The two electric rubber wheels 39 can have a clamping effect on the angle steel; Among them, the punching assembly 4 includes a long groove 41. The long groove 41 is opened in the middle靠右 of the L-shaped plate 22. A collecting box 42 is fixedly installed at the bottom of the long groove 41. A top plate 43 is fixedly installed at the top of the long groove 41. Two hydraulic punching rods 44 are fixedly installed on the inner side of the top of the top plate 43. A first fixing plate 45 is fixedly installed on the front side of the two hydraulic punching rods 44. Two first hydraulic rods 46 are fixedly connected to the inner side of the first fixing plate 45. The telescopic ends of the two first hydraulic rods 46 are fixedly connected with a "川" - shaped block 47; The top plate 43 is fixedly installed on the top of the bottom plate 1. When the two hydraulic punching rods 44 expand and contract, they can pass through the long groove 41. The tail end of the "川" - shaped block 47 is made of rubber and can contact the L-shaped plate 22 under the movement of the two first hydraulic rods 46; Increase the stroke of the two first hydraulic rods 46, push the "川" - shaped block 47 to fit the angle steel on the surface of the L-shaped plate 22 again. At this time, the extrusion force of the "川" - shaped block 47 and the clamping forces of the clamping plate 35 and the two electric rubber wheels 39 can ensure the stability of the angle steel on the L-shaped plate 22. At this time, increase the stroke of the two hydraulic punching rods 44 again to perform a punching operation on the angle steel. The waste material cut by milling will fall into the collecting box 42 from the long groove 41, and the waste material collection can be completed; The discharging assembly 6 includes two second fixed plates 61, the two second fixed plates 61 are fixedly mounted on the top of the bottom plate 1, a step plate 63 is rotatably mounted in the middle of the two second fixed plates 61, a second motor 62 is fixedly mounted on the right side of the rotating shaft of the step plate 63, a first crawler 64 and a second crawler 65 are fixedly mounted on the top and left side of the step plate 63, and a third crawler 66 is fixedly mounted on the front side of the second crawler 65; the first crawler 64, the second crawler 65 and the third crawler 66 are all driven by electric motors, and the third crawler 66 is fixedly mounted on the top right side of the bottom plate 1; The first crawler 64 and the second crawler 65 in a vertical relationship are started at the same time to receive the angle steel. When the angle steel completely leaves the cutting assembly 5, the second motor 62 is started. The second motor 62 rotates counterclockwise to drive the step plate 63 to flip. At this time, the angle steel will flip over and fall into the third crawler 66. The material can be unloaded by transporting it through the third crawler 66. After flipping, the angle steel will be inverted on the surface of the third crawler 66 in a triangular state. Firstly, it can improve the stability during transportation, and secondly, it is convenient to stack multiple angle steels to save space.

[0019] Working principle: When using the present invention, first feed the angle steel, place the angle steel in the L-shaped plate 22, start the clamping assembly 3, the second electric wheel 31 moves in the track 26, and drives the entire clamping assembly 3 to move. After determining the appropriate position, start the first motor 33 to rotate the connecting plate 34 in the direction of the longitudinal plate 32. When the connecting plate 34 and the longitudinal plate 32 are at a vertical angle, the clamping plate 35 connected to the connecting plate 34 can adjust the angle steel placed on the L-shaped plate 22. When the electric rubber wheel 39 contacts the angle steel, it will be forced to squeeze the first spring 38 through the circular shaft 37. After the first spring 38 is forced, it will resume its stroke. The two electric rubber wheels 39 can have a clamping effect on the angle steel. Rotating the electric rubber wheel 39 can push the angle steel from left to right; while the electric rubber wheel 39 is rotating, start the first electric wheel 25, and through the connecting rod 24, the push block 23 can also have a pushing effect on the angle steel on the surface of the L-shaped plate 22; When the angle steel moves to the position of the punching assembly 4, the electric rubber wheel 39 and the push block 23 are stopped. First, the stroke of the two first hydraulic rods 46 is increased to push the "Chuan" block 47 to fit the angle steel to the surface of the L-shaped plate 22 again. At this time, the squeezing force of the "Chuan" block 47 and the clamping force of the clamping plate 35 and the two electric rubber wheels 39 can ensure the stability of the angle steel on the L-shaped plate 22. At this time, the two hydraulic punching rods 44 increase their strokes again to punch holes in the angle steel. The scraped materials will fall from the long groove 41 into the collection box 42 to complete the collection. After the punching operation is completed, the Sichuan block 47 moves away, and the electric rubber wheel 39 and the push block 23 are restarted to move the angle steel and transport the angle steel to the cutting assembly 5. The angle steel will first enter the through slot 57 of the trapezoidal block 54, but at this time the angle steel may not be in the center position of the through slot 57. At this time, the rubber telescopic block 59 moves upward. The rubber telescopic block 59 presents a trapezoidal design with a narrow upper and a wide lower part. During the continuous upward movement, the angle steel will be clamped in the through slot 57. At this time, the stroke of the two second hydraulic rods 52 is increased to drive the cutter 53 to cut the angle steel. The impact force generated during cutting can be slightly alleviated by the two second springs 58. When the two second hydraulic rods 52 are started, a sudden inertia will be generated, resulting in shaking. Therefore, the four telescopic rods 55 are adjusted accordingly. After absorbing the impact force, they are restored to the predetermined range again to complete the initialization. After the cutting is completed, the rubber telescopic block 59 descends, and the push block 23 and the electric rubber wheel 39 push again. The angle steel after being punched and cut will move to the discharge assembly 6 again. At this time, the first crawler 64 and the second crawler 65 in a vertical relationship are started at the same time to receive the angle steel. When the angle steel completely leaves the cutting assembly 5, the second motor 62 is started, and the second motor 62 rotates counterclockwise to drive the step plate 63 to flip. At this time, the angle steel will flip over and fall into the third crawler 66, and be transported by the third crawler 66 to complete the unloading.
