Abstract
The invention belongs to the technology of repair of stamping dies, and relates to an improved method for repairing a reinforcing pit on a planar profile of a metal plate stamping die. Repairing steps includes expanding the reinforcing pit; manufacturing inserts of the reinforcing pit; repairing the reinforcing pit; and polishing the profile of the die. The method for repairing the reinforcing pit on the planar profile of the die is improved, the shortcoming that the surface of the die is uneven due to technological inserts collapse when the die is pressed during usage is overcome, and the quality of a product is guaranteed.
Description
Technical field
The invention belongs to the diel maintenance technique, relate to strengthening the improvement of nest method for repairing and mending on the profile of metal plate punching mould plane.
Background technology
In the product development stage, the reinforcement nest position on the profile of metal plate punching mould plane is changed through regular meeting, and correspondingly mould also need be changed, and need repair former reinforcement nest, and increase the new nest of strengthening.Fig. 1 repairs the cutaway view of strengthening nest on the profile of front mold plane.Present method for repairing and mending is: inlay cylindrical technology and insert at former reinforcement nest 2 places on mould 1, and the technology of inlaying is inserted and former reinforcement nest interference fit.Its shortcoming is: owing to cylindrical technology insert with die body when assembling gas can't discharge and owing to the technology reasons such as deflection takes place when strengthening the assembling of nest expanded hole of inserting have caused technology to insert and unreal phenomenon is pressed in the bottom surface of strengthening the nest expanded hole.Therefore reprocess the back and in the mould use, insert and subside, cause the uneven defective of die surface after reprocessing, cause product overproof even scrap because of technology often takes place pressurized.
Summary of the invention
The objective of the invention is: propose on the profile of a kind of mould plane to strengthen the method for repairing and mending of nest, subside, cause the uneven defective of die surface, guarantee product quality to eliminate in the use to insert because of pressurized generation technology.
Technical scheme of the present invention is: strengthen the method for repairing and mending of nest on the profile of a kind of mould plane, it is characterized in that: the step of repairing is following:
1, the reinforcement nest is repaiied in expansion: the method for employing milling is repaiied 2 expansions of the reinforcement of the circle on mould 1 profile nest and is truncated cone-shaped; Make the port diameter of strengthening nest 2 greater than the bottom surface diameter, the side of strengthening nest 2 is a taper seat, cone angle=7 °～15 °; The bottom surface of strengthening nest 2 is the plane; Reinforcement nest after expansion repaiied is called waits to inlay the reinforcement nest, strengthens the corresponding position of nest and bores sunk screw via hole of system with waiting to inlay at the back side of mould 1, and the axis of this sunk screw via hole is with to wait to inlay the reinforcement nest coaxial;
2, making the reinforcement nest inserts: adopt with mould identical materials manufacturing reinforcement nest and insert 3; It is identical with minor diameter bottom surface diameter and the cone angle of waiting to inlay the reinforcement nest to strengthen insert 3 minor diameter bottom surface diameter and cone angle of nest; Strengthen nest and insert 3 axial height, waiting to inlay tapped blind hole of minor diameter bottom center brill system of strengthening nest than waiting to inlay the big 0.2mm～0.5mm of the degree of depth that strengthens nest;
3, repair to strengthen nest: will strengthen nest and insert and 3 embed to wait to inlay and strengthen in the nest, and pass and be screwed into the reinforcement nest with sunk screw 4 from the sunk screw via hole at mould 1 back side and insert in 3 the tapped blind hole, will strengthen nest and insert and 3 be fixed on and wait to inlay in the reinforcement nest;
4, reconditioning die face: the profile of grinding die 1 again on grinding machine guarantees to strengthen nest insert 3 upper surface and other part coplanes of die face.
Advantage of the present invention is: improved on the profile of mould plane the method for repairing and mending of strengthening nest, having eliminated in the use inserts because of pressurized generation technology subsides, causes the uneven defective of die surface, has guaranteed product quality.
