During use, use controller 11 to control motor one to drive sprocket one 12 to rotate, and sprocket one 12 to rotate to drive chain 14 to rotate positively and negatively, and the positive and negative rotation of chain 14 impels slide block one 21 to slide left and right on body 1, making the downward pressure The body 23 drives the main pressure head 3 and the pressure dividing head 4 to move to the top of the movable mold 6, and the motor 2 52 drives the screw shaft 51 to rotate to adjust the horizontal distance between the pressure dividing head 4 and the main pressure head 3. When the pressure head is 4, the steel wire rope 572 can be pulled by the motor 4 571 to drive the pressure divider 4 to rise, so that the pressure divider 4 is separated from the main pressure head 3; when the fixed mold 7 is needed, only the movable mold 6 needs to be replaced by the fixed mold 7 is enough; select the movable mold 6 or the fixed mold 7, when the movable mold 6 is selected, manually slide the movable mold 6, adjust the distance between the movable mold 6, adjust the distance between the movable mold 6 and the main pressure head 3, and adjust the movable mold 6 After the distance from the pressure divider 4 is adjusted, the movable mold 6 and The body 1 is fixed, and the distance between the roller body 2 61 and the body 1 is fine-tuned with the hydraulic cylinder 3 62 to improve the influence of the roller body 2 61 on the forming accuracy of the sheet metal part 8; when the fixed mold 7 is selected, it is formed according to the sheet metal part 8 Choose the die 71 according to the shape of the die, manually adjust the distance between the dies 71, put the block 72 between the dies 71, combine the die 71 and the block 72 through the shape of the sheet metal part 8, and adjust the fixed After mold 7, fixed mold 7 and body 1 are fixed by a plurality of screw holes 2 provided on movable mold 6, grooves 1 provided on body 1 for screws to pass through, screws and nuts; fixed mold 7 and body 1 are fixed; After die 7, use the controller 11 to control the motor 2 52 to drive the screw shaft 51 to rotate positively and negatively, and the two motors 2 52 independently drive the corresponding screw shaft 51 to rotate positively and negatively respectively, and change the respective corresponding pressure divider 4 and main pressure The distance of the head 3; when the pressure dividing head 4 needs to be used, the shaft sleeve 1 58 is driven to rotate by the motor 3 59, so that the shaft sleeve 58 moves from the hinge shaft 1 54 to the hinge of the hinge shaft 1 54 and the hinge shaft 2 55 , fix hinge axis 1 54 and hinge axis 2 55, and keep hinge axis 1 54 and hinge axis 2 55 in a straight line; when the pressure divider 4 is not needed, motor 4 571 is rotated in the forward direction, and the wire rope 572 is contracted to make the hinge There is relative rotation between the second shaft 55 and the first hinge shaft 54, and the second hinge shaft 55 is lifted, so that the pressure divider 42 rises, which prevents the pressure divider 4 from interfering with the work of the main pressure head 3. When the pressure divider 4 needs to be used, The motor four 571 rotates in reverse, the wire rope 572 is slack, and the stretched spring one resets the pressure divider 4, so that the pressure divider 4 and the hinge shaft two 55 remain in the vertical direction; at the same time, the shaft sleeve one 58 is moved down , the hinge shaft 1 54 is fixedly connected with the hinge shaft 2 55, so that the hinge shaft 1 54 and the hinge shaft 2 55 are easy to bear and transmit force; after the sheet metal part 8 is placed on the movable mold 6, it is controlled by the controller 11 The pressing module 2 presses down the main pressure head 3 and the sub-pressure head 4. The main pressure head 3, the sub-pressure head 4 and the movable mold 6 cooperate with each other to bend the sheet metal part 8. During this process, the hydraulic cylinder 2 42 fine-tuning roller body one 43 in vertical The height in the direction makes the roll body 1 43 make the forming size of the sheet metal 8 conform to the standard when the sheet metal 8 is pressed down, which can improve the forming precision of the sheet metal 8; 44 drives the roller body 1 43 to rotate, so that the roller body 2 61 presses the sheet metal part 8 into the desired shape in a rotating manner when forming the sheet metal part 8; after the sheet metal part 8 is bent and formed, the controller 11 Control the hydraulic cylinder one 22 to drive the main pressure head 3 and the partial pressure head 4 to rise, and take out the formed sheet metal part 8 .
