Preferably, the material of described two groups of cams is carbon constructional quality steel
A kind of die-cutting machine quadric chain of the present utility model is owing to having adopted above technical scheme, make the die-cutting machine quadric chain when cross cutting or die-cut action, make active force be evenly distributed in the whole plane of upper bolster, make upper bolster when finishing cross cutting or die-cut action, stressed even, resetting is accurate, die-cut pressure stability, for the large scale product die cutting or when die-cut, its structure stress is more evenly distributed, and pressure is more steady.
Below in conjunction with accompanying drawing a kind of die-cutting machine quadric chain of the present utility model is described further.
Description of drawings
Fig. 1 is the structural representation of a kind of die-cutting machine quadric chain of the utility model.
Each mark is as follows among the figure: 1 upper bolster, 2 frames, 3 four groups of connecting rods, 4 four upper guide posts, 5 four lower leads, 6 elevating brackets, 7 buffer units, 8 liang of group cams, the high-accuracy gear of group more than 9,10 die shoes.
The specific embodiment
A kind of die-cutting machine quadric chain of the present utility model mainly comprises upper bolster 1, frame 2, four groups of connecting rods 3, four upper guide posts 4, four lower leads 5, elevating bracket 6, buffer unit 7, two groups of cams 8, organizes high class gear 9 and die shoe 10 more.Four groups of connecting rods 3 are that four groups of parallel connecting rods form, and two groups of cams 8 are comprised of two groups of cams that generation rotatablely moves.Frame 2 fixedly mounts on the ground, and the lower end of four lower leads 5 is fixedly mounted on frame 2 inner bottom surface, and buffer unit 7 is enclosed within four lower lead 5 outer surfaces, and the upper end of four lower leads 5 is slidingly connected with elevating bracket 6 and is vertical with elevating bracket 6.The lower end of four upper guide posts 4 is fixedly mounted on the elevating bracket 6 by nut and is vertical with elevating bracket 6, and the upper end of four upper guide posts 4 is passed die shoe 10 and is fixedly mounted on the upper bolster 1, and vertical with upper bolster 1.Two groups of cam 8 two ends are fixed on the die shoe 10, and the upper end of four groups of connecting rods 3 is fixedly connected with two groups of cams 8, and the lower end of four groups of connecting rods 3 is fixedly connected with elevating bracket 6, organize high class gear 9 and two groups of cams 8 mesh by gear more.
Frame 2, upper bolster 1, die shoe 10, elevating bracket 6 adopt high-quality grey cast-iron HT300, adopt annealing, tempering to eliminate internal stress and process, and under climate change and impact forces, do not produce distortion.Four groups of connecting rods 3 adopt Forging Technology, and material is high-quality GB spheroidal graphite cast-iron QT500, eliminates stress through annealing, tempering, and the die structure is strong.Four upper guide posts 4 and four lower leads 5 adopt carbon constructional quality steel to process through modified high frequency, and case hardness is the HRC60 degree, forms through precise finiss again, has well wearability and stability.The material of two groups of cams 8 is carbon constructional quality steel, and by heat treatment, comprehensive mechanical property is splendid, and the resistance to shock loads performance is high.The high-accuracy gear 9 of many groups material be respectively carbon constructional quality steel through modified, high frequency is processed, import high density MC nylon and spheroidal graphite cast-iron QT500 form, the engagement that combines, noise is little, wearing coefficient is high, active force is stablized.
When die-cutting machine starts, at first by the rotation of motor driving belt pulley, produce moment of torsion by belt pulley and be delivered to many group precision gears 9 by main shaft, drive two groups of cams 8 that mesh with its gear by many groups precision gear 9, two groups of cams 8 rotarily drive the upper end motion that is fixed on four groups of connecting rods 3 on two groups of cams 8, the motion of four groups of connecting rods 3 drives elevating bracket 6 motions that are fixedly connected on four groups of connecting rod 3 lower ends, the motion of elevating bracket 6 drives four upper guide posts, 4 motions that are fixedly connected with, pass die shoe 10 by four upper guide posts 4 at last and drive upper bolster 1 motion that is fixedly connected with, because the mechanism of two groups of cams 8, so that above a series of motion is for moving back and forth.Be installed with cutting die on the upper bolster 1, realize that upper bolster 1 finishes cross cutting or die-cut action.
Four groups of connecting rods 3 form by producing reciprocating four groups of connecting rods, and four groups of reciprocating power that connecting rod produces thus are evenly distributed in the whole plane of upper bolster 1, make upper bolster 4 when cross cutting (or die-cut) moves, stressed even, resetting is accurate, die-cut pressure stability.The cutting die of this die-cutting machine all is mounted on the upper bolster 1, therefore the stability of upper bolster 1 operation directly can cause the fraction defective of product.
Two groups of cams 8 form by producing two groups of cams that rotatablely move by the motor driving gear engagement, and drive four groups of connecting rods 3, and the power reciprocating that is produced by connecting rod again is being used for fixing and the upper bolster 1 of cutting die is installed.
In the process of cross cutting or die-cut action movement, elevating bracket 6 can pump, and in this process, elevating bracket 6 is to rely on four lower leads 5 to play the fixed support effect, utilizes simultaneously buffer unit 7 to play cushioning effect.
Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
