The outer periphery of the screw 23 is fixedly sleeved with a positioning sleeve 21 near the bottom end, and the top and bottom of the positioning sleeve 21 are fixedly installed with an annular member by bolts, which fits on the support seat 2, and the annular member can further limit the rotation position of the screw 23 on the support seat 2, thereby playing a role in strengthening the support, and the outer periphery of the positioning sleeve 21 is fixedly installed with a bearing by bolts, and the outer periphery of the bearing is engaged in the support seat 2, and the bottom end of the screw 23 passes through the positioning sleeve 21 and is fixedly connected with the power output end of the first servo motor 22 by bolts, and the outer peripheries of two adjacent screws 23 are threadedly sleeved with a support plate 24, and the screw 23 is driven to rotate by the first servo motor 22, so that the support plate 24 can be adjusted in height by means of the threaded engagement force between the screw 23, and the speed of up and down movement can be adjusted by changing the rotation speed;The guide rail 3 is fixedly installed on the bottom of the adjacent sides of the two support plates 24 by bolts. There are at least two guide rails 3, and the two guide rails 3 are arranged in parallel. The outer sliding sleeve of the guide rail 3 is provided with two sliders 31. The two sliders 31 are symmetrically arranged with the center point of the guide rail 3. By providing two guide rails 3, the stability of the slider 31 during movement can be further improved. A cutting head 32 is detachably installed at one end of the bottom of the slider 31. By detachably installing the cutting head 32, it is convenient for the user to replace and maintain it at any time. The second servo motor 33 is fixedly installed on the top of the separated sides of the two support plates 24 by bolts. The power output end of the second servo motor 33 The screw rod 34 is fixedly installed through the support plate 24 by bolts, and the two sliders 31 are respectively threadedly sleeved with the outer periphery of the two screw rods 34. The lateral position of the slider 31 can be adjusted during the rotation of the screw rod 34 by means of the threaded sleeve, thereby driving the cutting head 32 to synchronously move, so as to achieve the cutting requirements of steel plates of different lengths. The two screw rods 34 are collinearly arranged, and the adjacent ends of the two screw rods 34 are rotatably installed with an adapter 35. The central axis of the adapter 35 is collinear with the central axis of the two screw rods 34. The two screw rods 34 are connected together by the adapter 35, which can further improve the stability of the screw rod 34 during the rotation process. 1 is provided with a reserved groove above the adjacent side, and the reserved groove is used to accommodate the adapter 35. The provision of the reserved groove can further improve the demand for small-size cutting of steel plates; the support frame 4 is fixedly installed above the base 1 by bolts, and a through hole 41 is provided in the middle of the support frame 4. Support plates 42 are slidably connected on both sides of the upper side of the support frame 4, and the steel plate to be cut can be supported by the support plates 42 to provide a force surface for the cutting of the cutting head 32. A limiting rod is fixedly installed on the support frame 4 by bolts, and the support plate 42 is slidably sleeved on the periphery of the limiting rod. The support plate 42 slides in the axial direction of the limiting rod, and the provision of the limiting rod can further limit the support plate 42 in To ensure smoothness during translational sliding, further guiding the sliding direction, a beam switch 43 is bolted to the top of the support plate 42 and the bottom of the slider 31. A drive assembly is provided on the support plate 42. The beam switch 43 provides an electrical signal to the drive assembly, allowing the two sliders 31 to synchronously adjust the distance between the two support plates 42 during movement. This facilitates the drop of the cut steel plate into the blanking hole 11, speeding up the unloading speed and improving cutting efficiency. The support plate 42 slides on the support frame 4 via the drive assembly; the laminating and leveling assembly is disposed within the blanking hole 11; and the lifting assembly is disposed around the periphery of the base 1.

[0026] Among them, the second servo motor 33 drives the screw rod 34 to rotate, and the position of the slider 31 on the guide rail 3 is adjusted by the threaded engagement force between the slider 31 and the screw rod 34, so that the cutting heads 32 located at the bottom ends of the two sliders 31 can move away from or close to each other, thereby achieving the selective adjustment of the cutting size of the steel plate. At the same time, with the help of the matching switch 43 provided between the support plate 42 and the slider 31, the position between the support plate 42 and the slider 31 is detected in real time by the matching switch 43, so that the driving component can synchronously adjust the position of the two support plates 42 on the support frame 4 to achieve the effect of synchronous adjustment matching the position of the slider 31. The screw rod 23 is driven to rotate by the first servo motor 22, and the support plate 24 is adjusted by the threaded engagement force between the screw rod 23. The support plate 24 is positioned so that the cutting head 32 can be driven downward by the support plate 24 to cut the steel plate above the support plate 42. The cut steel plate enters the blanking hole 11 by gravity, and the bottom of the steel plate is coated by the coating and leveling component, so that the cut steel plate can avoid scratching and bumping the steel plate below during the blanking process, and also avoid the defect of bending caused by the corners of the steel plate above contacting the steel plate below. By dropping the cut steel plate horizontally onto the collecting plate 12, the steel plate can be effectively protected. After the cut steel plates are stacked, the height of the base 1 is adjusted by the lifting component, the collecting plate 12 is removed from the base 1, and the cut steel plates can be taken out through the collecting plate 12.

[0027] Example 2:

[0028] The difference from the previous embodiment is that the drive assembly includes: a first rope 45, which is fixedly installed on one end of the support plate 42 by bolts; a second rope 46, which is fixedly installed on the other end of the support plate 42 by bolts; a first winder 44, which is fixedly installed on both sides of the periphery of the base 1 by bolts; one end of the first rope 45 is wound around the winding end of the first winder 44, and one end of the second rope 46 is wound around the winding end of the first winder 44, and the winding directions of the first rope 45 and the second rope 46 at the winding end of the first winder 44 are opposite.

[0029] Among them, by driving the first winder 44, the first rope 45 and the second rope 46 can be synchronously wound up, and through the pulling action of the first rope 45 and the second rope 46, the support plate 42 can slide in a directional manner on the support frame 4. By changing the winding direction of the first winder 44, the sliding direction of the support plate 42 on the support frame 4 can be effectively adjusted, thereby adjusting the relative position between the two support plates 42, thereby cooperating with the two cutting heads 32 to implement cutting and blanking effects of steel plates of different lengths.

[0030] Example 3:

[0031] The difference from the second embodiment is that, in this embodiment, the film leveling assembly includes: a mounting groove 5, which is opened on both sides of the base 1 in the blanking hole 11, and the bottom of the two mounting grooves 5 are fixedly installed with a bracket 51 by bolts, and one end of the bracket 51 is fixedly installed with a second winder 52 by bolts, and the winding ends of the two second winders 52 are wrapped with a transparent film 53, and the width of the transparent film 53 is not less than the width of the through hole 41, so that the cut steel plate can be implemented. A six-axis robot arm 54 is set on the base 1, and the six-axis robot arm A suction cup frame 55 is fixedly installed on the output end of the robotic arm 54 by bolts. The suction cup frame 55 is composed of multiple pneumatic suction cups installed on a circular frame. Infrared sensors are embedded in the four ends below the suction cup frame 55. The infrared sensors can effectively detect the relative position of the suction cup frame 55 and the cut steel plate. Electric heating wires 56 are fixedly installed on all four sides of the suction cup frame 55 by bolts. The heating effect of the electric heating wires 56 can melt the transparent film 53 around the steel plate, so that the transparent film 53 attached to the bottom of the steel plate can be unloaded together with the steel plate.

[0032] Among them, the steel plate entering the blanking hole 11 falls onto the transparent film 53, and by adjusting the winding amount of the two second winders 52, the steel plate and the transparent film 53 fall smoothly onto the collecting plate 12. At this time, the six-axis robotic arm 54 extends into the blanking hole 11 and drives the suction cup frame 55 to fit above the steel plate. The steel plate is adsorbed and grasped by the adsorption effect of the suction cup frame 55, and then repositioned to the center of the transparent film 53 to ensure that the steel plate is in the center of the transparent film 53. Then, the transparent film 53 at the edges of the steel plate is melted by the heating wire 56, so that the steel plate and the transparent film 53 fall onto the collecting plate 12 together, so that the cut steel plate can avoid scratches on the steel plate below due to impact during the blanking process, and can also avoid the risk of bending the corners of the steel plate above due to impact.

[0033] Example 4:

[0034] The difference between this embodiment and the third embodiment is that the lifting assembly includes: a hydraulic telescopic rod 6, which is fixedly installed on the periphery of the base 1 by bolts, and the telescopic end of the hydraulic telescopic rod 6 is set downward; the power output end of the hydraulic telescopic rod 6 is fixedly installed with a base plate 61 by bolts, and positioning grooves 62 are provided on the four edges below the bottom of the base 1, and a positioning rod 63 is movably inserted in the positioning groove 62. The bottom end of the positioning rod 63 is fixedly connected to the base plate 61 by bolts, and a transparent glass plate is embedded in the middle of one side of the periphery of the base 1 to facilitate users to observe the stacking amount of internal steel plates.

[0035] Among them, by synchronously driving the four hydraulic telescopic rods 6, the base 1 can be lifted with the help of the support of the bottom plate 61, so that it is convenient for users to disassemble and assemble the collection plate 12, thereby achieving the effect of convenient unloading. At the same time, in conjunction with the positioning rod 63 provided in the positioning groove 62 of the base 1, the stability of the base 1 during the lifting process can be further improved.

[0036] Working principle: When in use, the second servo motor 33 drives the screw rod 34 to rotate, and the threaded engagement force between the slider 31 and the screw rod 34 adjusts the position of the slider 31 on the guide rail 3, so that the cutting heads 32 at the bottom ends of the two sliders 31 can move away from or close to each other, thereby achieving the effect of selecting and adjusting the cutting size of the steel plate. At the same time, with the help of the shooting switch 43 provided between the support plate 42 and the slider 31, the shooting switch 43 detects the position between the support plate 42 and the slider 31 in real time, so that the driving component can synchronously adjust the two support plates 42 The position of the support frame 4 is adjusted to match the position of the slider 31 to achieve synchronous adjustment. The screw 23 is driven by the first servo motor 22 to rotate, and the position of the support plate 24 is adjusted by the threaded engagement force between the support plate 24 and the screw 23. With the help of the support plate 24, the cutting head 32 is driven to move downward, so that the steel plate above the support plate 42 can be cut. The cut steel plate enters the blanking hole 11 by gravity, and the first rope 45 and the second rope 46 can be synchronously wound by driving the first winder 44. 5 and the pulling effect of the second rope 46, so that the support plate 42 can slide in a directional manner on the support frame 4, and the sliding direction of the support plate 42 on the support frame 4 can be effectively adjusted by changing the winding direction of the first winder 44, thereby adjusting the relative position between the two support plates 42, thereby cooperating with the two cutting heads 32 to implement cutting and blanking effects of different lengths of steel plates, and the steel plates entering the blanking hole 11 fall onto the transparent film 53, and by adjusting the winding amount of the two second winders 52, the steel plates and the transparent film 53 fall smoothly onto the collecting plate 12. At this time, the six-axis machine The mechanical arm 54 extends into the blanking hole 11 and drives the suction cup frame 55 to fit above the steel plate. The steel plate is adsorbed and grabbed by the adsorption effect of the suction cup frame 55, and then repositioned to the center of the transparent film 53 to ensure that the steel plate is in the center of the transparent film 53. The transparent film 53 at the edges of the steel plate is melted by the heating wire 56, so that the steel plate and the transparent film 53 fall onto the collection plate 12 together, thereby preventing the cut steel plate from being scratched by the impact on the steel plate below during the blanking process, and also avoiding the risk of bending the corners of the steel plate above due to impact.
