CN105057496A - Process for fabricating stretched toast baking boxes - Google Patents

Abstract

The invention discloses a process for fabricating stretched toast baking boxes. The process comprises the following steps: 1, material preparation, wherein an imported aluminum-plated panel of high quality is adopted, the thickness of the aluminum-plated panel is below 1.0 mm, material adoption specifications are calculated ready, and then cutting is conducted separately according to the material specification required by each toast box; 2, mold preparation, wherein molds required for each procedure are prepared ready; 3, high-pressure stretching, wherein after being sleeved with plastic high-pressure stretching bags with thickness being 3-4 silk, the materials are placed on a 100-200t hydraulic machine for being stretched; 4, reshaping, wherein semi-finished products which are stretched ready are placed onto a 100t hydraulic machine for being reshaped; 5, edge trimming, wherein the boxes which are reshaped ready are sequentially placed onto a 100-200t pneumatic punching machine for being subjected to edge-trimming, flanging and opening-edge outward rolling for forming round edges, and finished products can be obtained. Compared with the prior art, the process has the advantages that manual work and cost required for fabricating the toast boxes are greatly reduced; cleaning is easy to conduct, and no sanitary angle exists; the structure is firm, and deformation is not prone to occurring; the service life is long.

Description

One stretching Toast cures the manufacture craft of box

Technical field

The present invention relates to bread baking apparatus preparation method, particularly relate to the manufacture craft that a kind of one stretching Toast cures box.

Background technology

At present, the toast in industry cure box be all with 1.2mm thickness within aluminium alloy plate or other five metals plate cut into several, then by bending, the fourth of the twelve Earthly Branches pressure or welding, these several plates are combined into the shape of a box.The toast adopting this technique to make cures the artificial many of box needs, and cost of labor is high; Make inside toast box and have gap, not easy to clean, there is corner or spot as yet untouched by a clean-up campaign; Adopt bending, fourth of the twelve Earthly Branches pressure or welding fabrication technique, structure is insecure, yielding; Service life is short, and raw-material consumption is large.

Summary of the invention

The present invention is to solve above-mentioned deficiency, provides the manufacture craft that a kind of one stretching Toast cures box.

Above-mentioned purpose of the present invention is realized by following technical scheme: a kind of one stretching Toast cures the manufacture craft of box, it is characterized in that: comprise the following steps:

(1) get the raw materials ready: the alclad sheet adopting the high-quality of import, thickness within 1.0mm, and calculates materials specification, then, and point material specification cut out needed for single toast box;

(2) mould is prepared: according to the operation of " stretch---shaping---the outer coiled round edge of trimming---flange---opening's edge ", get out the mould required for each operation;

(3) high pressure stretches: material is packaged the thick high pressure stretched plastic bag of 3-4 silk and go up the stretching of 100-200t hydraulic press afterwards; As: stretching depth is within 100mm, and the small-sized toast box of length and width within 120mm then stretches with 100t hydraulic press;

(4) shaping: by 100t hydraulic press shaping on the semi-finished product that stretch, make corner angle more tiny, shape is more perfect;

(5) edge finishing: the box after shaping go up successively 100-200t(etui then with 100t) pneumatic punching machine trimming, flange, opening's edge outward coiled round edge get product.

The present invention's advantage is compared with prior art:

1, the artificial and cost of labor made required for toast box is greatly reduced;

2, make inside toast box and there is no gap, easy to clean, there is no corner or spot as yet untouched by a clean-up campaign;

3, whole plate one drawing and forming, makes sound construction, not yielding;

4, the toast box made compared with the fourth of the twelve Earthly Branches pressure or welding toast box service life on to grow more than 10 times, greatly reduce raw-material consumption.

Detailed description of the invention

Below in conjunction with embodiment, the present invention is described in further detail.

Embodiment 1: a kind of one stretching Toast cures the manufacture craft of box, comprises the following steps:

(1) get the raw materials ready: the alclad sheet adopting the high-quality of import, thickness within 1.0mm, and calculates materials specification, then, and point material specification cut out needed for single toast box;

(2) mould is prepared: according to the operation of " stretch---shaping---the outer coiled round edge of trimming---flange---opening's edge ", get out the mould required for each operation;

(3) high pressure stretches: material is packaged 4 thick high pressure stretched plastic bags and go up the stretching of 200t hydraulic press afterwards;

(4) shaping: by 100t hydraulic press shaping on the semi-finished product that stretch, make corner angle more tiny, shape is more perfect;

(5) edge finishing: outside the box after shaping being gone up successively the trimming of 200t pneumatic punching machine, flange, opening's edge, coiled round edge gets product.

Embodiment 2: a kind of one stretching Toast cures the manufacture craft of box, comprises the following steps:

(1) get the raw materials ready: the alclad sheet adopting the high-quality of import, thickness within 1.0mm, and calculates materials specification, then, and point material specification cut out needed for single toast box;

(2) mould is prepared: according to the operation of " stretch---shaping---the outer coiled round edge of trimming---flange---opening's edge ", get out the mould required for each operation;

(3) high pressure stretches: material is packaged 3 thick high pressure stretched plastic bags and go up the stretching of 100t hydraulic press afterwards;

(4) shaping: by 100t hydraulic press shaping on the semi-finished product that stretch, make corner angle more tiny, shape is more perfect;

(5) edge finishing: outside the box after shaping being gone up successively the trimming of 100t pneumatic punching machine, flange, opening's edge, coiled round edge gets product.

The present invention has overturned the manufacture craft of toast box in current industry, adopts special material of aluminizing, and by overlapping drawing die combination, whole alclad sheet just can be made box-shape when pressing without the need to any fourth of the twelve Earthly Branches or welding when making more.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
