Abstract
The invention discloses an integral molding process for a profile. The integral molding process for the profile comprises the steps of 1) cutting: cutting a raw material according to needed length; 2) small hole punching: punching a small molding hole which can facilitate strip-shaped profile bending at a position which is required to be bent; 3) bending; 4) large hole finish cutting. The integral molding process for the profile disclosed by the invention has the advantages that the process is simple, the efficiency is high and metallic frames with high structural stability can be quickly manufactured; since the vertical parts of the strip-shaped profile are not fully cut off when the small molding hole is punched but certain distance is reserved to form a reinforcing connecting part, after the profile is bent, the vertical parts on the two sides of the small molding hole can be connected to form an integrated connecting structure without using a welding process or other connecting parts, the overall structural strength is effectively increased, the stability is good, the appearance is attractive, the welding process is not used, and not only can the production process of the traditional metallic frames be effectively simplified and can the production efficiency be improved, but also the saving of energy and production raw materials can be facilitated and the production cost is decreased.
Description
Technical field
The present invention relates to profile shapes bending and molding technology, be specifically related to a kind of profile shapes integral forming process.
Background technology
Metal framework is widely used in various product at present, as it is medium to be applied in the display of electronic product.Its structure is normally combined into a metal framework with four elongated workpiece.
Existing metal framework manufacture craft is by being to have a V-type notch the corner of strip metal material is die-cut in advance, the shape of cross section of strip metal material is L-type normally, this strip metal material comprises horizontal part and vertical portion, V-type notch cuts off vertical portion substantially, then by this V-type notch, carry out bending and molding, form a metal framework.The structural stability of such metal framework is not high, because vertical portion is cut off, without the part that is connected.For improving structural stability, people conventionally adopt welding or by other connector, the vertical portion of V-type notch both sides are connected.Cause production cost too high, and operation is various, affects production efficiency.
China's publication number " 101669744A ", name is called " method for manufacturing metal frame ", and it discloses and aluminium strip has been made into ' ∏ ' shape moulding; Dual-side at ' ∏ ' shape moulding is made some ' V ' shape notch, both ends is made to hypotenuse, at the screw that the bottom surface making fixed support of ' ∏ ' shape moulding is used; Moulding is done to surface treatment; Moulding is bent into designed picture frame shape along ' V ' shape notch place.' V ' shape notch that is it is also that the vertical portion of aluminium strip is cut off completely, and its structural stability is poor.
China's publication number " 101422803 ", name is called " metal frame manufacture method ", has announced a kind of metal frame manufacture method, first, takes the material of bundle shape metal framework from storage rack; Seeing through leveling feeder equipment is long lath by the material leveling of metal framework; See through impact style predetermined rivet hole position and several screw holes position are set on long lath, and be respectively provided with bending gap in predetermined three bending places of this long lath, and do the processing of metal framework external form in this long lath outer rim; By the long lath roll extrusion after perforating by punching, it is the long slab stripe shape body that section is " L " type; The long slab stripe shape body that this section is to " L " type, according to metal framework moulding length, is cut; Long slab stripe shape body after this is cut, in this bending place, by bending matched in clearance, bending is also overlapped into 90 degree right angles, and three bending places complete after bending, are shaped to metal framework jaggy; By the breach of this metal framework, by this rivet hole position, be stacked mutually, and this breach of punch riveting, be shaped to a complete metal framework.Same, this bending gap is also that the vertical portion of long slab stripe shape body is cut off completely, by bending matched in clearance, bending is also overlapped into 90 degree right angles, and three bending places complete after bending, are shaped to metal framework jaggy, comparatively speaking, its structural stability is also poor.
China's publication number " 101723229A ", name is called " manufacture method of escalator frame ", it provides a kind of manufacture method of escalator frame, wherein, this escalator frame arranges in the mode of crossing between upper floor and bottom floor, and formed by a plurality of shaped steel combinations, in the manufacture method of this escalator frame, one that reserves shaped steel forms limit, and on other formation limit, form continuous otch, and this notch shape is become and comprised and the described corner part that formation limit is crossing reserving, then with the angle of regulation, carry out bending machining, afterwards, at least at groove part, weld and form inflection point.Same, this otch is also that the vertical portion of angle steel is cut off completely, is the stability of lift structure, its technical scheme adopting is the vertical portion of welding or carrying out angle cleat by set square adopting.Because having increased welding sequence or having increased the attaching parts such as set square, cause manufacturing process various, affect production efficiency, and increased production cost.
Summary of the invention
