Embodiment 2

[0045] In use, the staff places the metal plate to be processed on the feeding frame 2 and places the material between the first positioning column 63 and the second positioning column 64, starts the processing switch, and controls the positioning oil cylinder 61 in multiple positioning assemblies to start at the same time through the controller in the control system, the positioning oil cylinder 61 drives the first positioning column 63 to move towards the second positioning column 64 arranged opposite to it, and multiple first positioning columns 63 abut against one side of the metal plate, so that the other side of the metal plate abuts against the second positioning column 64, that is, the first positioning column 63 and the second positioning column 64 are used to correct the position of the metal plate, and the accuracy of subsequent processing is ensured.

[0046] After the position of the material is corrected, the pushing mechanism is started, the pushing mechanism is started by the pushing motor 31, the control gear 32 is rotated, the gear 32 and the rack 33 are engaged and transmitted, so that the gear 32 moves forward during rotation, and the pushing frame 3 moves forward, the lower clamping block 3531 of the clamping assembly in the clamping assembly installed on the pushing frame 3 moves to the lower side of the metal plate, the clamping oil cylinder 351 is controlled to start, the extension end of the clamping oil cylinder 352 moves upward, so that the rear end of the clamping plate 353 moves upward, because the clamping plate 353 is installed on the clamping seat 353 through the rotating shaft, the front end of the clamping plate 353 moves downward, that is, the clamping and fixing of the metal plate are completed by the downward movement of the upper clamping block 3521 and the lower clamping block 3531, and then the forward movement of the pushing frame 3 is realized to push the metal plate to move forward, and the feeding operation is completed,

[0047] The punching and cutting device 100 cuts the metal plate to process a plurality of metal round plates. According to the processing requirements, sometimes the width of the metal plate can meet the cutting of two metal round plates, and the transverse movement of the metal plate is needed to complete the feeding operation. The transverse movement of the metal plate is controlled by the transverse movement driving mechanism installed on the bottom support frame 1. The transverse driving motor 71 is started, the change of the rotation direction and the transmission are completed through the three-head bevel gear steering device 72 and the two-head bevel gear steering device 74, the rotation of the lead screw 75 is controlled, and then the transverse movement of the feeding frame 2 connected with the lead screw 75 is controlled, thereby realizing the control of the transverse movement of the metal plate of the feeding frame 2. Example 3

[0048] A lifting separation mechanism is arranged between the feeding frame 2 and the punching and cutting device 100. When the transverse driving motor 71 controls the transverse movement of the feeding frame 2 to drive the transverse movement of the metal plate, the front part of the metal plate is lifted by the separation column 41 controlled by the lifting oil cylinder 42, so that the metal plate 41 is separated from the lower die 101 in the punching and cutting device 100, and the friction between the metal plate and the lower die 101 during the transverse movement is avoided to prevent the metal plate from being deflected, thereby further ensuring the processing precision of the material.

[0049] The material tail feeding mechanism is designed to solve the movement friction between the material and the lower die 101 and the transverse movement control when the tail end of the material moves to the position between the feeding frame 2 and the punching and cutting device 100. At this time, the metal plate is not located on the feeding frame 2, but is located on the tail feeding column 51. The tail feeding column 51 in the material tail feeding mechanism is moved left and right by the transverse movement of the feeding frame 2, and the tail feeding column 51 drives the transverse movement of the metal plate. When the separation column 41 is lifted, the metal plate is lifted by starting the oil cylinder 52 to control the upward movement of the tail feeding column 51, so that the metal plate does not contact the lower die 101 during the transverse movement, thereby avoiding the problem of the deflection of the metal plate caused by the friction between the metal plate and the lower die 101.

[0050] When the pushing mechanism pushes the metal plate to move close to the lower die 101 of the punching and cutting device 100, and the tail end of the metal plate is punched and cut, in order to prevent the position of the clamping plate 352 of the clamping assembly from affecting the position of the punching and cutting, the servo motor 341 corresponding to the movement of the clamping assembly is started to control the movement of the moving frame 343, so that the clamping assembly can move without affecting the punching and cutting of the tail end of the metal plate.
