Abstract

The invention discloses a die insert modular machining method which comprises the following steps of: (1) machining bolt via holes and pin holes on rectangular blank of each insert, and positioning the center line of each hole on each insert blank on a certain intersection point of a square grid formed by longitudinally and horizontally arranging grid lines; (2) fixing each insert blank on a standard cushion plate fixed with a workbench of a small numerical control machining center by bolts and pins, machining the appearance of each insert by the machining center, and reserving margins on the matching surface with a die holder in each insert; and (3) finishing machining the matching surface with margins of each insert. The die insert modular machining method can machine the die insert without a large numerical control machining center, and the insert can be directly assembled with the die holder without scrapping after being machined, thus effectively improving the die production efficiency and reducing the work load of large equipments; and simultaneously, the insert has easy replacement and is convenient for the repair of the die, thus reducing the production and maintenance costs of the die.

Description

Die insert modular machining method

Technical field

The present invention relates to the processing method of mould, specifically, relate to a kind of die insert modular machining method.

Background technology

The particularly large-scale stamping die of mould often adopts edge to piece together structure, inlays on the die holder of upper and lower mould and inserts, and is spliced into the punching press position of punch-die by inserting, and carries out punch process such as blanking, side cut, flange.At present, the processing method of inserting commonly used is as follows: elder generation processing bolt via hole and pin-and-hole on the rectangular billet of inserting, the position of bolt via hole and pin-and-hole is that the bolt via hole on same mould or different mould are respectively inserted is different with the pin-and-hole position according to the arrangements of respectively inserting; The bolt via hole that to respectively insert again and pin-and-hole and die holder are joined brill, processing screw hole and pin-and-hole on die holder, to insert with bolt and pin and to be fixed on the die holder, to insert and die holder together is fixed on the large-sized numerical control machining center and processes, the profile that processes die holder simultaneously and insert, but the face that matches with die holder on respectively inserting need be reserved surplus, by pincers worker itself and die holder bedding-in is processed at last.The shortcoming of this traditional diamond-making technique is: the processing of inserting must be processed with Large Machining Center, has increased the live load of main equipment; And insert at last by pincers worker itself and die holder bedding-in, having increased the assembly work amount of pincers worker, production efficiency is low; The more important thing is, after mould uses, certain piece is inserted and is damaged when needing to change, the die holder of large-scale heaviness together must be transported back, the blank of inserting is fixed on carry out centering processing on the die holder, this just makes that the maintenance of mould is very inconvenient, transportation, maintenance cost have been increased, and insert and also must take the large-sized numerical control machining center, waste device resource, the utilization that main equipment is more optimized for one of processing.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of die insert modular machining method, it need not use the large-sized numerical control machining center just can process inserting, inserting does not need bedding-in to get final product directly after machining and the die holder assembling, it can effectively improve the production efficiency of mould, reduces the live load of main equipment; Simultaneously, insert and change easily, be convenient to mold repair, reduce production, the maintenance cost of mould.

For solving above technical problem, technical scheme of the present invention is as follows: a kind of die insert modular machining method, carry out as follows: (1), on the rectangular billet of respectively inserting processing bolt via hole and pin-and-hole, described each centerline hole on each blank of inserting is positioned on certain intersection point of the square net that each netting twine arranges in length and breadth; (2), the described blank of respectively inserting is fixed on the standard cushion plate with miniature numerical control machining center stationary table by bolt and pin, then with the described profile of respectively inserting of this Cutter Body Processing with Machining Center, in respectively inserting with on the mating surface of die holder, put made allowance; (3), to continue on described miniature numerical control machining center with the described described pin-and-hole of respectively inserting be benchmark, fine finishining is respectively inserted and is placed with the mating surface of surplus, until reaching the design size requirement;

Described standard cushion plate, it is uniform porose flat board, described each hole is arranged on each intersection point of the crisscross square net of netting twine, and the minimum single foursquare length of side of this grid equates that with the minimum single foursquare length of side on described the inserting screw section and pin-and-hole section are arranged on described each hole; Have mounting groove on the two relative side of described flat board.

The present invention adopts modularity processing to inserting, with the relative position and the distance between borehole standardization of respectively inserting between last bolt via hole and pin-and-hole, each hole all is distributed on the level or vertical bar of arranging between homogeneous phase, and the distance in each hole is the multiple of a certain constant, and this constant is exactly the minimum single foursquare length of side in the square net.Like this, insert just can be fixed on easily and be arranged with on the standard cushion plate of screw and pin-and-hole by same square net, on a standard cushion plate, a plurality of inserting can be installed simultaneously, because the contour dimension of standard cushion plate can be fixed on standard cushion plate on the miniature numerical control machining center and process inserting much smaller than die holder.In respectively inserting with the mating surface of die holder finally thus machining center finish for benchmark fine finishining with the pin-and-hole, do not need bedding-in directly to assemble with die holder.And therewith adaptably, the arrangement regulation that installation screw on the die holder and pin-and-hole are also gone up each hole by inserting is arranged.

As preferred embodiment a kind of, the minimum single foursquare length of side of described square net is 25mm.Apart from unit, be convenient on inserting, arrange each hole site as minimum aperture.

As preferred embodiment a kind of, described each hole is the identical shoulder hole of size, and this hole is followed successively by screw section and pin-and-hole section downwards from the end face of described flat board.Same Kong Zhongjun at each grid intersection point has screw and pin-and-hole, is convenient to install insert.

As preferred embodiment a kind of, described pin-and-hole section is divided into two sections up big and down small straight holes, is respectively first pin-and-hole and second pin-and-hole.But two kinds of pins of two pin-and-hole plug-in mounting different-diameters.

As preferred embodiment a kind of, described standard cushion plate is a rectangular slab, and the cross section of described mounting groove is a T shape.

The invention has the beneficial effects as follows: it only uses the miniature numerical control machining center just can process die insert, and can process a plurality of inserting simultaneously, inserting does not need bedding-in to get final product directly after machining and the die holder assembling, the production efficiency that can improve mould is more than 30%, and the live load of reduction numerical control machining center, save production cost; Simultaneously, when mold repair, only need to process separately inserting, die holder need not be transported back, change and insert easily, be convenient to mold repair, the maintenance cost of mould is low.
