Description

Die cutting die bending and breaking integrated device

Technical Field

Background

In general, complex patterns of cartons, paper boxes, plastics and various artworks are produced, and the processes of die cutting, indentation and the like are carried out on raw materials by using corresponding cutting dies, so that mass and efficient production can be realized. And the production of the cutting die requires the cutting forming processing of a strip-shaped steel knife by using a special cutting die processing machine.

In the production and processing process of the cutting die, bending and shearing operations are generally carried out by adopting a cutter bending machine according to requirements, and the bending and shearing are integrated into a whole by the existing cutter bending machine so as to ensure shearing accuracy, namely, the effect that one set of die can be used for bending and shearing is achieved.

since the inner mold 50 is supported by steel material and the slit 51 is a hole formed in the steel material, the cross-sectional shape of the steel material is changed due to the presence of the slit hole, resulting in uneven stress distribution. Around the slot, stress is concentrated at the slot edge because the cross-sectional area at this location is smaller and the stress is determined by both the force and the cross-sectional area. The stress concentration can cause plastic deformation or fracture of the steel around the slot hole, thereby affecting the strength and service life of the steel, in order to avoid the occurrence of the situation, stress holes 57 communicated with the slot 51 are respectively formed at two ends of the slot 51, the stress concentration is reduced through the stress holes 57, and the internal mold 50 is placed to fracture, wherein, because the two slots 51 are adopted in the utility model and the two slots 51 are communicated, the stress holes 57 are arranged at two ends of the communicated slot 51 formed by combining the two slots 51;

because the outlet 53 of the knife slit 51 is provided with the clearance chute 54, the inner wall of the outer mold 60 is spaced from the outer wall of the inner mold 50 due to the clearance chute 54, at the moment, the shearing force of the outer mold 60 is insufficient when rotating due to the spacing, the situation that smooth shearing cannot be realized easily occurs, in order to avoid the situation, the bottom of each knife slit 51 is provided with a shearing area 58, the shearing area 58 is an area which is not covered by the clearance chute 54, the outer wall of the inner mold 50 is tangential to the inner wall of the outer mold 60, when shearing is needed, the inner mold 50 can be lifted, so that the part of the knife material to be sheared is positioned in the shearing area 58, and at the moment, the outer mold 60 forms shearing force with the inner mold 50 when rotating, thereby realizing shearing of the knife material; the height of the shearing area 58 is equal to or greater than the height of the knife material, so that the knife material can be sheared smoothly, and tearing is avoided.

It should be noted that, the recess value of the avoidance space 56 needs to be determined according to the error value of the cutter, and if the thickness error of the cutter is positive or negative 0.03 mm, the recess value of the avoidance space 56 needs to be greater than 0.03 mm.

Further, in this embodiment, a bending opening 61 is formed at the top of the outer mold 60, the upper end and the lower end of the bending opening 61 are equal in width, a cutout 62 is formed below the bending opening 61, the upper end width of the cutout 62 is greater than the lower end width, the lower end width of the cutout 62 is equal to or greater than the width of the knife slot 51, and the bottom of the outer mold 60 is flat;

specifically, a bending opening 61 for bending and a shearing opening 62 for shearing are formed in the outer die 60, when the cutter material is required to be bent, the cutter material is positioned in the bending opening 61 by lifting the outer die 60, and the cutter material can be bent by rotating the outer die 60 at the moment, wherein the upper end and the lower end of the bending opening 61 are equal in width, so that the bending opening 61 directly acts on the whole cutter material during bending, and force is synchronously applied, so that the bending accuracy and flatness of the cutter material can be ensured; when shearing is needed, the cutter is positioned in the shearing opening 62 by lifting the outer die 60, and the outer die 60 is rotated at the moment, so that the shearing of the cutter can be realized, wherein the upper end width of the shearing opening 62 is required to be smaller than the lower end width so that the outer die 60 shears from bottom to top when rotating, and the sliding of the outer die 60 is facilitated due to the structural design of the upper width and the lower small upper width; to ensure that the sliding of the outer die 60 is not affected by the thickness of the knife, the lower end width of the cutout 62 needs to be equal to or greater than the smallest slot 51;

in order to facilitate the connection between the outer die 60 and the outer driving mechanism 40, the outer driving mechanism 40 drives the outer die 60 to rotate, the bottom of the outer die 60 is flat and is matched with the mold groove 46 of the outer driving die sleeve 41, and when the bottom of the outer die 60 is inserted into the mold groove 46, the outer driving die sleeve 41 can drive the outer die 60 to rotate without other fasteners under the design of the structure.

Further, the outer mold 60 is further provided with a relief port 63 corresponding to the bending port 61 and the shear port 62, and the width of the relief port 63 is larger than the width of the bending port 61;

specifically, since the cutter material will pass through the outer die 60, both the front and rear sides of the outer die 60 need to be opened, wherein the bending opening 61 and the cutting opening 62 are located at the front side, since the outer die 60 will rotate, in order to avoid the situation that the opening at the rear side of the outer die 60 is propped against the cutter material due to insufficient reserved positions, and the bending is not in place or the cutting is not in place, the rear side of the outer die 60 needs to be provided with the avoiding opening 63, and the width of the avoiding opening 63 needs to be larger than the width of the bending opening 61, so that when the outer die 60 rotates to the maximum angle required to be bent, the rear side of the outer die 60 will not contact with the cutter material due to the existence of the avoiding opening 63, and the cutting is the same.

In summary, the clearance is arranged in the knife gap, so that the overall flatness of the knife after bending is realized, the die cutting performance of the knife is improved, the die cutting effect is ensured, the inner die is not required to be polished, the service life of the die is prolonged, the manual polishing procedure is omitted, and the use is more convenient; the internal mold and the external mold are controlled by the independent control mechanisms respectively, and the internal mold and the external mold can move relatively, so that shearing or bending accuracy is improved on the basis of realizing a smooth bending effect, and simultaneously, the conditions of use conflict of bending and shearing are avoided.
