The sliding plate 62 is elastically connected with the supporting seat 1 through a spring, so that the sliding plate 62 can automatically reset under the elasticity after the limit of external force is lost. The two support rods 61 are kept away from the equal fixedly connected with link 64 of one end of supporting seat 1, and link 64 is connected with swinging plate 66 through connecting rod 65 rotation, and swinging plate 66 passes through torsional spring and link 64 elastic connection, and swinging plate 66 presents the incline condition under the effect of torsional spring, and when swinging plate 66 clockwise swings, can promote sliding plate 62 forward.
Further, the blanking mechanism 6 further comprises a special-shaped rod 67, one end of the special-shaped rod 67 is fixedly arranged on the upper die 44, and the other end of the special-shaped rod 67 is fixedly provided with a jacking block 68. When the upper die 44 moves downwards, the special-shaped rods 67 are synchronously driven to move downwards, and when the special-shaped rods 67 move downwards, the special-shaped rods are contacted with the upper surface of the swinging plate 66 and push the swinging plate 66 to rotate anticlockwise, so that the purpose of abdication is achieved. In the process of moving up the upper die 44, the ejector block 68 is driven to move upwards through the special-shaped rod 67, the ejector block 68 is contacted with the lower surface of the swinging plate 66, and the swinging plate 66 is driven to rotate clockwise, so that blanking is realized.
In this embodiment, the oil immersing mechanism 7 includes an oil tank 71, the oil tank 71 is located at the front side of the supporting seat 1, and the oil tank 71 is filled with oil. The oil tank 71 fixed mounting is on supporting seat 1, and slidable mounting has fretwork board 73 on the inner wall of oil tank 71, is equipped with a plurality of through-holes on the fretwork board 73, and the fuel feeding passes through, and the top fixed mounting of fretwork board 73 has spacing frame 72, and spacing frame 72 slidable mounting is on oil tank 71, and the inner wall of spacing frame 72 passes through spring and oil tank 71 elastic connection. When the plate spring is pushed by the blanking mechanism 6 to be separated from the fixed die mechanism 3, the plate spring can fall on the hollowed-out plate 73, so that the plate spring is prevented from falling into the oil tank 71 directly, and oil drops are prevented from splashing everywhere.
Working principle: first, a plate to be punched is placed on the lower die 32, and the rear portion of the plate is brought into contact with the front portion of the limiting plate 51, thereby achieving positioning in the front-rear direction. The lower surface of the plate is in contact with the upper surfaces of the two pallets 22, preventing the plate from tilting due to the curvature of the lower die 32. The left and right ends of the plate are positioned between the two positioning plates 23, so that the plate is positioned in the left and right directions.
After the plate is placed, the oil cylinder 41 is started, the output end of the oil cylinder 41 contracts and drives the lifting frame 42 to move downwards, the lifting frame 42 drives the upper die 44 to move downwards through a spring, and the plate is formed by pressing. When the plate is pressed, the plate can be bent downwards to deform, the two ends of the plate can drive the supporting plate 22 to move downwards, and when the two ends of the plate are bent to a certain angle, the plate can be separated from the supporting plate 22, and at the moment, the supporting plate 22 can automatically reset under the elasticity of the springs.
During the downward movement of the lifting frame 42, the connecting plate 59 is synchronously driven to move downward. The connecting plate 59 synchronously drives the driving racks 510 at two ends of the connecting plate to move downwards, and after the plate is pressed and molded, the driving racks 510 are meshed with the transmission gear 58. Continued downward movement of the elevator 42 then causes the springs at the bottom to be compressively deformed, thereby maintaining the position of the upper die 44. The rack 510 is driven to move downwards, so that the transmission gear 58 is driven to rotate by engagement, and the transmission gear 58 drives the first connecting plate 54 to move circularly through the rotating shaft 52. The first connecting plate 54 drives the bottom end of the second connecting plate 55 to move, so that the inclination angle of the second connecting plate 55 is changed. The top end of the second connecting plate 55 and the guide shaft 56 are limited by the vertical groove 511 and the arc-shaped groove 512, and firstly the guide shaft 56 moves downwards along the vertical groove 511, and when the guide shaft 56 moves to the bottom end of the vertical groove 511, the bending cylinder 57 thereon contacts with the plate. Then, under the rotation of the rotation shaft 52, the guide shaft 56 enters the arc-shaped groove 512 and drives the bending cylinder 57 to perform circular motion around the rotation shaft 52, so as to bend the end of the plate.
When the upper die 44 moves downwards, the special-shaped rods 67 are synchronously driven to move downwards, and when the special-shaped rods 67 move downwards, the special-shaped rods are contacted with the upper surface of the swinging plate 66 and push the swinging plate 66 to rotate anticlockwise, so that the purpose of abdication is achieved. When the top block 68 on the special-shaped rod 67 moves to the lower part of the swinging plate 66, the swinging plate 66 can automatically yield under the elasticity of the torsion spring, and the inclined state is maintained.
Then, the output end of the oil cylinder 41 is lifted, and the lifting frame 42 and the upper die 44 are driven to reset. In the process of moving up the upper die 44, the top block 68 is driven to move upwards by the special-shaped rod 67, and the top block 68 contacts with the lower surface of the swinging plate 66 and drives the swinging plate 66 to rotate clockwise. The top end of the swinging plate 66 pushes the sliding plate 62 forward in the swinging process, and the sliding plate 62 is pushed forward by the plate spring processed and pressed by the pushing plate 63, so that the plate spring falls on the hollowed-out plate 73, the hollowed-out plate 73 increases in weight and moves downward, so that the plate spring is immersed in oil, and tempering is performed.
