Lamp stand door processing mold and processing technology thereof
The present invention relates to a kind of lamp stand door processing mold and processing technology thereof, belong to forming processing technology field.
Lamp stand door processing mode bottom existing light fixture is: first bottom lamp stand, cut a hole, then is welded into a kidney-shaped frame with two iron plate docking, finally this frame is welded in the edge in lamp stand hole.
There is following defect in above-mentioned processing mode: 1) because it is by different parts are combined to form lamp stand door, in the process of welding, weld part forms weld seam, affects crudy; 2) lamp stand door that different component combination becomes easily causes the waste of material in process; 3) this kind of processing mode operation is various, wastes time and energy, and homogeneity of product is poor, stability is bad; 4) weld seam that welding is formed affects product appearance.
Summary of the invention
The present invention is directed to above-mentioned defect, object is that providing a kind of improves crudy, time saving and energy saving lamp stand door processing mold and processing technology thereof.
The technical solution used in the present invention is for this reason: the present invention includes mould bases and be arranged on the upper die and lower die on mould bases, described patrix is provided with an inner chamber, inner chamber is provided with a upper punch, upper punch is provided with to be gone out the main drift of waist-shaped hole and goes out the auxiliary drift of support by lamp stand door, formed and space corresponding to the shaping rear profile of waist-shaped hole inside described patrix and outside drift, section and lamp stand outer surface correspondence under patrix; Described counterdie upper surface and lamp stand inner surface correspondence, counterdie forming surface and described patrix, upper punch correspondence.
Described mould bases is provided with mould principal arm, the ejecting mechanism of location counterdie and lamp stand, described mould bases is L-type structure, transverse part and the vertical portion of L-type mould bases establish locating hole respectively, and described ejecting mechanism is located by located lateral hole, and described mould principal arm is by longitudinal register hole, ejecting mechanism location.
Described mould principal arm is provided with the boss that size is greater than longitudinal register hole, and mould principal arm passes longitudinal register hole and makes described boss withstand on side, longitudinal register hole, and mould principal arm is located by bolt by the opposite side in longitudinal register hole.
The present invention carries out according to the following steps:
1) first will to be set in outside lamp stand to be processed on mould principal arm and to locate;
2) patrix undershoot, makes lamp stand processing department form desired aperture position;
3) patrix continues undershoot, and the cooperation due to upper die and lower die makes waist-shaped hole shaping, and the spatial vertical distance formed between inside patrix and outside drift forms waist-shaped hole flange height.
Advantage of the present invention is: 1) the present invention carries out the shaping of lamp stand door on same parts lamp stand, and in forming process, do not produce weld seam, it maintains the overall performance of product, and the mechanical performance of product is improved; 2) the present invention does not need to adopt additional materials in forming process, and utilizes lamp stand itself shaping, avoids the waste of material, reduces manufacturing cost; 3) the present invention adopts punch forming, compares traditional welding procedure, and its working (machining) efficiency increases substantially, and the uniformity of its product is good, constant product quality; 4) product that the present invention is formed does not produce weld seam, and product is attractive in appearance, is easily esthetically acceptable to the consumers; 5) the present invention does not use welding rod, reduces electric power energy consumption, and effectively reduces the exhaust emission of welding to environment, decreases the pollution to environment.

Detailed description of the invention
The present invention is as shown in Figure 1: comprise patrix 2, counterdie 2, mold base 5, mould principal arm 3 and liftout attachment 4; Its Each part form is as follows:
1) patrix 1: the lamp stand profile of its lower surface profile and correspondence is corresponding, and offers drift inner chamber, establishes cross section to be the drift of I shape in inner chamber and it longitudinally extends to intracavity bottom always, has certain spatial joint clearance inside inner chamber He outside drift;
Counterdie 2: corresponding with described patrix 1, has the groove corresponding with described drift, its contoured upper surface and corresponding lamp stand profile correspondence;
When patrix 1 and counterdie 2 coordinate: first patrix 1 moves downward, when it contacts with lamp stand to be processed, punching press is carried out to lamp stand in drift lower surface, makes the datum hole position that lamp stand surface is formed and described drift is corresponding; Further patrix 1 continues to move downward, by the cooperation of patrix 1, counterdie 2, to be in outside drift and inside inner chamber between the lamp stand portion at position be subject to patrix 1, counterdie 2 relative motion extruding shaping to upper overturning, support is also shaping in company with flange simultaneously, forms waist-shaped hole.
2) mould principal arm 3: in order to locate counterdie 2 and lamp stand to be processed, mould principal arm 3 establishes the placement surface corresponding with counterdie 2 lower surface, placement surface is provided with counterdie 2 correspondence position the positioner both be connected, and it is outer and locate that lamp stand is set in mould principal arm 3, and mould principal arm 3 establishes boss.
3) liftout attachment 4: comprise one and bearing device corresponding to lamp stand outline to be processed and support the support column of this bearing device.
4) mold base 5: in L-type structure, its plane of structure and vertical face are respectively equipped with locating hole, and wherein plane of structure locating hole is connected with the support column of liftout attachment 4, the locating hole jig principal arm 3 in vertical face; Its version is: the side of mould principal arm 3 being withstood longitudinal register hole through longitudinal register hole to mould principal arm 3 boss, the opposite side then in longitudinal register hole realizes the location of mould principal arm 3 by connectors such as bolts.
After each mold component is in place by the present invention, first patrix 1 moves downward and goes out position, hole, and then patrix 1 continues to move downward, and door flange is shaping, door submounts companion is simultaneously routed up; After shaping, patrix 1 is braked and return, and then liftout attachment 4 moves upward and the blanking demoulding.
