The clamping head locks a glass board tightly in stretching according to the lever principle; the motor provides the stretching power through the drive mechanism; the number of the clamping heads at each side can increase or decrease according to the side lengths of the organic glass board, thereby stretching glass boards with different dimensions uniformly.
Description
Technical field
The utility model relates to the aerial organic glass production field.
Background technology
Aviation with lucite need under the uniform temperature condition to the lucite raw sheet planar two-way Uniform Tension to given size, to improve the performances such as impact strength, stress solvent crazing, fracture toughness.Traditional stretcher has two kinds of calendering formula and biaxial tension formulas, and the lucite area that the calendering formula is produced is little, generally is no more than 800 * 800mm, can not satisfy instructions for use.Traditional biaxial tension formula stretching-machine adopts the mode of manual upper chuck, manual locking, moved by hand abduction, has that percent defective is high, automaticity is low, labor strength is large and the shortcoming such as stretching efficient is low.
The utility model content
The utility model purpose provides the two-way even Automatic-drawing device of a kind of lucite, two-way Uniform Tension problem when solving stretching lucite raw sheet, can improve product quality and production efficiency, the rate of reducing the number of rejects and seconds and workman's labour intensity satisfies modern Production requirement.
Technical scheme: the utility model is implemented by the following technical programs:
The two-way even Automatic-drawing device of a kind of lucite is characterized in that: by dop (1), expanding sleeve (3), stretching bar (4), unfold mechanism (2), girder (6), auxiliary beam (5), auxiliary beam retaining mechanism (7), screw mechanism (8), chain-drive mechanism (9), reduction box (10), motor (11) and form;
Up and down two Surface Contacts of one end and lucite raw sheet during described dop (1) work, dop (1) other end is connected 4 with expanding sleeve (3) with the stretching bar) be connected; Expanding sleeve (3) one ends are connected with auxiliary beam (5), the two ends of each expanding sleeve (3) respectively with unfold mechanism (2) and be connected; Auxiliary beam (5) is connected with auxiliary beam retaining mechanism (7); Stretching bar (4) passes in the middle of expanding sleeve (3), and stretching bar (4) one ends are connected with girder (6); Girder (6) is connected with screw mechanism (8), and screw mechanism is connected with reduction box (10) by chain-drive mechanism (9), and reduction box (10) is connected with motor (11).
Described poly (methyl methacrylate) plate is square; The quantity of each checkpost head (1) can increase according to the length of side of poly (methyl methacrylate) plate or reduce the square poly (methyl methacrylate) plate of the different size that can stretch.
Advantage and effect: by the utility model lucite raw sheet that can two-wayly stretch equably, and this process does not need artificial participation automatically to finish.
Concrete advantage of the present utility model and good effect are:
1, the lucite raw sheet that can two-wayly stretch equably, all dop spacings and the amount of tension of this stretching device are identical, improve product thickness evenness, can not produce local excessive in problems such as poly (methyl methacrylate) plate drawing cracks.
2, drawing process does not need artificial participation automatically to finish, and enhances productivity, and the operator is freed from heavy manual labor.

Description of reference numerals:
Dop, 2. unfold mechanism, 3. expanding sleeve, 4. stretching bar, 5. auxiliary beam, 6. girder, 7. auxiliary beam retaining mechanism, 8. screw mechanism, 9. chain-drive mechanism, 10. reduction box, 11. motors, 12. poly (methyl methacrylate) plates.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is lucite plate stretching schematic diagram, and as shown in the figure, middle thick line is the state before the lucite plate stretching, and the size of poly (methyl methacrylate) plate is less, and the spacing of dop (1) is less; The empty fine rule of outside is the state behind the lucite plate stretching, the spacing of dop (1) is larger, and dop (1) is subject to the effect of outside pulling force by stretching bar (4) and girder (6), and the arrow indication among Fig. 1 is exactly the direction that applies pulling force, make the attenuation of lucite plate thickness, the length of side increases; Unfolding mechanism evenly increases the spacing of dop; Poly (methyl methacrylate) plate is square; The quantity of each checkpost head (1) increases or minimizing the poly (methyl methacrylate) plate of the different size that can stretch according to the length of side of poly (methyl methacrylate) plate.
Fig. 2 is dop automatic clamping structure schematic diagram, as shown in the figure, the Automatic-drawing device by dop (1), expanding sleeve (3), stretching bar (4), unfold mechanism (2), girder (6), auxiliary beam (5), auxiliary beam retaining mechanism (7), screw mechanism (8), chain-drive mechanism (9), reduction box (10), motor (11) etc. and form;
Described dop (1) one end is connected with the lucite raw sheet, and dop (1) other end is connected 4 with expanding sleeve (3) with the stretching bar) be connected; Expanding sleeve (3) one ends are connected with auxiliary beam (5), the two ends of each expanding sleeve (3) respectively with unfold mechanism (2) and be connected; Auxiliary beam (5) is connected with auxiliary beam retaining mechanism (7); The stretching bar passes in the middle of expanding sleeve (3), and stretching bar (4) one ends are connected with girder (6); Girder (6) is connected with screw mechanism (8), and screw mechanism is connected with reduction box (10) by chain-drive mechanism (8), and reduction box (10) is connected with motor (11).
As shown in Figure 2, the folding of dop (1) is to utilize lever principle.When auxiliary beam (5) is locked by retaining mechanism (7), motionless with the dop body that auxiliary beam (5) is connected by expanding sleeve (3), screw mechanism (8) drives girder (6) and stretching bar (4) the closed poly (methyl methacrylate) plate that clamps of dop (1) when moving right, screw mechanism (8) drive girder (6) and stretching bar (4) when being moved to the left dop (1) open; Behind the lucite board clamping, auxiliary beam (5) and girder (6) locking, screw mechanism (8) drives girder (6) and dop (1) etc. and moves right together, makes the poly (methyl methacrylate) plate under tension.
Four limits of foursquare poly (methyl methacrylate) plate are subjected to the effect of impartial pulling force, make the attenuation of poly (methyl methacrylate) plate even thickness, and the length of side increases, and realize improving the purpose of the performances such as impact strength, stress solvent crazing, fracture toughness.
