DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figures 1 to 5 As shown, a high-precision sheet metal cutting and shaping device described in an embodiment of the present invention includes a processing table 1; a bracket 12 is fixedly connected to the top of the processing table 1; a linear motor 13 is fixedly connected to the middle of the bracket 12; an electric cylinder 14 is fixedly connected to the output end of the linear motor 13; a cutting mechanism 15 is fixedly connected to the bottom of the output end of the electric cylinder 14; an adjusting component is installed on the top of the processing table 1; a first pressure rod 16 is rotatably connected to the middle of the adjusting component; a pair of pull ropes 17 are fixedly connected to the bottom of the other end of the first pressure rod 16; a pedal 18 is fixedly connected to the bottom end of the pair of pull ropes 17; when working, the sheet metal to be cut is placed on the processing table 1, and the adjustment The position of the entire sheet metal is adjusted so that the sheet metal is in the correct cutting position, and then the first pressure rod 16 is pressed down so that the first pressure rod 16 is pressed on top of the sheet metal. At the same time, the pedal 18 is stepped on to increase the pressing force of the first pressure rod 16 on the sheet metal. After completion, the cutting mechanism 15 is started to cooperate with the operation of the linear motor 13 and the electric cylinder 14 to cut the sheet metal. Since the sheet metal is pressed by the first pressure rod 16, it will not move easily, thereby reducing the movement of the sheet metal caused by the cutting force of the cutting mechanism 15. Through the above structure, the force offset of the sheet metal can be reduced when cutting the sheet metal, thereby improving the cutting accuracy of the sheet metal.
[0025] like Figures 1 to 3As shown, the side wall of the cutting mechanism 15 is fixed with a fixed block 2; the side wall of the fixed block 2 is symmetrically arranged and rotatably connected to a pair of push rods 21; the bottom end of the push rod 21 is fixed with a second pressure rod 22; a first spring 23 is fixed between the pair of push rods 21; during operation, as the operation of the electric cylinder 14 drives the cutting mechanism 15 to press down to cut the sheet metal, the pair of push rods 21 will synchronously descend, so that the pair of second pressure rods 22 press on the top of the first pressure rod 16, thereby increasing the pressing force of the first pressure rod 16 on the sheet metal. At the same time, as the operation of the linear motor 13 drives the cutting mechanism 15 to move for cutting, the pair of second pressure rods 22 will move above the first pressure rod 16, so that the sheet metal can be continuously pressed near the cutting position. Through the above structure, the pressing force near the cutting position of the sheet metal can be further improved, the occurrence of sheet metal offset can be further reduced, and the cutting accuracy of the sheet metal can be improved.
[0026] like Figures 1 to 4 When the cam 32 is in the closed position, the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down again, and the first spring 31 is pressed down
[0027] like Figures 1 to 2 As shown, the adjustment component includes a screw 4; the screw 4 is threadedly connected to the middle of the processing table 1; the top of the screw 4 is rotatably connected to the support 41; the first pressure rod 16 is rotatably connected to the middle of the support 41; during operation, when cutting sheet metal parts of different thicknesses, the height of the support 41 is adjusted according to the thickness of the sheet metal part by rotating the screw 4, so that when the first pressure rod 16 presses the sheet metal part, the bottom of the first pressure rod 16 can fit more closely with the top of the sheet metal part. Through the above structure, the device can press sheet metal parts of different thicknesses, improve the pressing effect of sheet metal parts of different thicknesses, and enhance the scope of application of the device.
[0028] like Figures 1 to 5As shown, the middle part of the pull rope 17 is slidably connected to a ring 5; a connecting rod 51 is fixed between a pair of the rings 5; when working, the pair of pull ropes 17 will expand outward due to the connecting rod 51, and at this time the pair of pull ropes 17 will not easily produce rotation and entanglement, thereby reducing the rotation of the pedal 18, so that the operator can step on the pedal 18 conveniently. Through the above structure, the occurrence of operational inconveniences caused by the rotation of the pedal 18 can be reduced, thereby improving the convenience of use of the device.
[0029] like Figures 1 to 3 As shown, the side wall of the fixed block 2 is fixedly connected to the limit rod 6; the limit rod 6 is located between a pair of ejector rods 21; during operation, when the cutting mechanism 15 completes cutting and rises with the operation of the electric cylinder 14, the pair of ejector rods 21 will approach each other due to the contraction of the first spring 23, and the setting of the limit rod 6 can limit the rotation angle of the pair of ejector rods 21, so that the bottom ends of the pair of ejector rods 21 will not be too close, thereby reducing the situation where the bottom ends of the pair of ejector rods 21 approach each other instead of expanding outward when cutting the sheet metal.
[0030] like Figure 3 As shown, the middle part of the second pressure rod 22 is rotatably connected to the roller 7; the surface of the roller 7 is a colloid material; through the above structure, the sliding friction between the second pressure rod 22 and the first pressure rod 16 can be converted into rolling friction, reducing the wear of the components and improving the service life of the components.
[0031] During operation, the sheet metal to be cut is placed on the processing table 1, the position of the sheet metal is adjusted so that the sheet metal is in the correct cutting position, and then the first pressing rod 16 is pressed down so that the first pressing rod 16 is pressed on the top of the sheet metal. At the same time, the pedal 18 is stepped on to increase the pressing force of the first pressing rod 16 on the sheet metal. After completion, the cutting mechanism 15 is started to cooperate with the operation of the linear motor 13 and the electric cylinder 14 to cut the sheet metal. Since the sheet metal is pressed by the first pressing rod 16, it will not move easily, thereby reducing the movement of the sheet metal caused by the cutting force of the cutting mechanism 15. When this happens, as the electric cylinder 14 drives the cutting mechanism 15 to press down and cut the sheet metal, the pair of push rods 21 will drop synchronously, causing the pair of second pressure rods 22 to press above the first pressure rod 16, thereby increasing the pressing force of the first pressure rod 16 on the sheet metal. At the same time, as the linear motor 13 drives the cutting mechanism 15 to move and cut, the pair of second pressure rods 22 will move above the first pressure rod 16, thereby continuously pressing the sheet metal cutting position attachment. When the position of the sheet metal needs to be adjusted, the end of the first pressure rod 16 is lifted to make the first pressure rod 16 The middle part of the rod 16 passes through the inclined slot 33 and squeezes the slider 32 into the interior of the fixed box 3, and finally the end of the first pressure rod 16 is located above the slider 32. The slider 32 will be pushed out under the action of the second spring 31 to support the first pressure rod 16 so that the first pressure rod 16 will not fall easily. After the adjustment of the sheet metal is completed, the first pressure rod 16 is pressed down again. The first pressure rod 16 will squeeze the slider 32 into the interior of the fixed box 3 again. When cutting sheet metal parts of different thicknesses, the screw 4 is rotated according to the thickness of the sheet metal to adjust the height of the support 41, so that the first pressure rod 16 When the sheet metal is pressed, the bottom of the first pressure rod 16 can fit more closely with the top of the sheet metal, and the pair of pull ropes 17 will expand outward due to the connecting rod 51. At this time, the pair of pull ropes 17 will not easily rotate and entangle, thereby reducing the rotation of the pedal 18, so that the operator can step on the pedal 18 conveniently. When the cutting mechanism 15 completes the cutting and rises with the operation of the electric cylinder 14, the pair of push rods 21 will approach each other due to the contraction of the first spring 23, and the setting of the limit rod 6 can limit the rotation angle of the pair of push rods 21, so that the bottom ends of the pair of push rods 21 will not be too close.
