Description

Technical Field

[0001] The utility model relates to a device for positive and negative bending of steel glass, in particular to a device for positive and negative bending of steel glass with a hard axis in a tempering furnace. Background Art

[0002] It is well known that in the tempered glass industry, when manufacturing curved tempered glass, the seat beam of the rigid-axis curved tempered wind grille equipment in the past was an overall horizontal non-adjustable structure, which could only process positive curved glass with a downward curvature, but could not process reverse curved glass with an upward curvature. In the market, positive bending usually requires a set of positive bending mechanisms, and reverse bending requires a set of reverse bending mechanisms, which not only wastes space but also increases the cost of tempered glass production. Summary of the Invention

[0003] In order to overcome the deficiencies in the background technology, the utility model discloses a tempering furnace hard-axis forward and reverse bending steel glass equipment.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0006] The tempering furnace hard-axis forward and reverse bending steel glass equipment has hinge seats fixed on both sides of the bottom plate of the frame, the bottoms of the cylinders on both sides are hingedly connected to the two hinge seats, and the lifting ends of the cylinders are hingedly connected to the two movable beam seat frames.

[0007] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0008] The hard-axis forward and reverse bending tempered glass equipment in the tempering furnace described in the utility model is realized by designing the frame into movable beam frames on both sides and a fixed beam frame in the middle. The movable beam frames on both sides are pushed and pulled by cylinders respectively to form a horizontal state or an inverted "V" shape, thereby realizing the functions of forward bending and reverse bending of glass on the same equipment. The utility model has a simple structure and is easy to use, and reduces the occupied area and the tempering production cost. BRIEF DESCRIPTION OF THE DRAWINGS

Cylinders 4 are hinged between the lower parts of the movable beam seat frames 3 on both sides and the bottom plate of the frame 1. Articulated seats are fixed on both sides of the bottom plate of the frame 1. The bottoms of the cylinders 4 on both sides are respectively hingedly connected to the two articulated seats, and the lifting ends of the cylinders 4 are respectively hingedly connected to the two movable beam seat frames 3; the fixed beam seat frame A bracket 6 is fixed between the lower part of 7 and the bottom plate of the frame 1, and ear plates are extended on both sides of the fixed beam seat frame 7. Pin holes 5 are opened on the ear plates. A trapezoidal extension block 9 is provided on the upper part of the inner end surface of the movable beam seat frame 3. The lower oblique side of the extension block 9 is fitted with the upper oblique side of the ear plate. A step 8 is provided at the rear part of the inner end surface of the movable beam seat frame 3, and a bearing seat 10 is fixed on the step 8. The bearing inner hole of the bearing seat 10 corresponds to the pin hole 5 front and back and is inserted with a pin shaft for rotation connection. The upper end of the fixed beam seat frame 7 is fixedly connected to the middle support of the lower arc of the upper and lower arc changing mechanism 2.
