Abstract

The utility model relates to a corrugated sheet forming mould. The utility model is characterized in that an upper and a lower moulds are respectively provided with a fixed knife and a movable knife, and the movable knife is supported by a spring and is higher at least one peak height than the fixed knife which is parallel with the movable knife. Because each tooth peak can be closed in turn when the mould is closed, the technical problem that the material can be fed freely in the process of the molding is solved. The mould which uses the technology can enhance the corrugated quality, and meanwhile, the operation efficiency is increased one time by shortening the molding period.

Description

The bimodal mould of corrugated plate

The bimodal mould of the corrugated plate that the utility model relates to belongs to diel.

Corrugated plate is a kind of sheet material of bellows-shaped, and it is used in the chemical tower, and its some interlaced repeatedly puts, and constitutes the tower tray with curved channel, the ripple packing that is otherwise known as, and it is extensive use in chemical tower.Two kinds of methods that this corrugated plate of present production generally adopts are gear hobbing moulding and unimodal die mould.Wherein the corrugated plate shortcoming through the gear hobbing moulding is, bellows-shaped is irregular to be subjected to tensile failure with the tooth root position because of material, and causes shorten service life.Unimodal forming method is because the peak pressure shape in a peak makes adjacent peak junction geometry can't guarantee that size is inaccurate.Molding cycle is long.

The purpose of this utility model is: a kind of bimodal mould of corrugated plate is provided, and with this formed in mould corrugated plate, speed is fast, quality good.

The technical solution of the utility model is: the bimodal mould of a kind of corrugated plate, has upper and lower template, it is characterized in that: the cutter of upward living is supported by the spring in the cope match-plate pattern groove, upper slitter with two tooth peaks, the position of at least one tooth peak height of cutter tooth alive peak on being lower than, fix with cope match-plate pattern, be slidingly matched between upper slitter and the cutter upward alive, cutter following alive with two tooth peaks, support by the spring in the lower bolster groove, following cutter tooth peak is fixed at the position and the lower bolster that are lower than at least one the tooth peak height of cutter tooth peak of living down, is slidingly matched between following cutter and the cutter down alive.

The technical program is the corrugated plate mould that places under the forcing press effect about a kind of, owing to the cutter peak is on the same template, not at grade, so the stroke distances of each tool setting peak closure does not wait.During matched moulds, upward live cutter and down the work cutter at first contact, after the two cutter closures, two tooth peaks of upper slitter contact closure step by step with corresponding counterdie tooth peak, thereby finish the moulding of two waveforms continuously, die sinking then, by the goods of moulding with the die sinking action automatic demoulding.

The advantage of present technique is: a mould assembling action is finished the moulding of two waveforms, than waveform before, presses forming technique once, increases work efficiency one times.In addition, the size for connection between per two waveforms, intrinsic by mould itself, each organizes the size for connection between the waveform, and mould guarantees that to the location of material so more regular than the geometry of prior art, size is accurate during by moulding.Because two waveforms are finished step by step, make moulding material one end location, the other end is in pan feeding under the free state all the time, has avoided the material local elongation.Therefore this mould structure has been realized moulding corrugated plate efficient height, the measured purpose of matter.

Below in conjunction with description of drawings embodiment of the present utility model.

Accompanying drawing is the structural representation of the bimodal mould of the utility model corrugated plate.

Among the figure; cope match-plate pattern (3) has a groove (1); spring (2) in the groove is supporting the cutter (4) of living; should go up live cutter and the upper slitter (5) that is fixed on cope match-plate pattern movingly; last opposite side of living cutter is located by locating piece (16); the tooth peak (6) of upper slitter; (7); than the low tooth peak height in last cutter tooth alive peak; a groove (19) is arranged in the lower bolster (12), and the spring (11) in the groove is supporting the cutter (8) of living down, and the following cutter of living has tooth peak (14); (15); the cutter of living down cooperates with the following cutter (9) that is fixed on lower bolster (12) is movable; opposite side is by locating piece (13) location, and the tooth peak of following cutter and locating piece are than low at least one the tooth peak height in cutter tooth peak of living down, during matched moulds; molding press moves down; in the stroke, at first go up the live cutter and the corresponding tooth of the cutter peak closure of living down, make the corrugated material location between them; continue matched moulds; the last cutter of living overcomes the spring (2) that supports it, makes spring (2) compression, and the tooth peak (6) of upper slitter is aimed at the cutter corresponding tooth peak (14) of living down and begun to press first waveform.At this moment, hold down the spring and the material bending briquetting pressure balance of the cutter of living, continue matched moulds, the spring balancing power that patrix begins to cross counterdie moves down, when the cutter of living instantly slides into horizontal level of following cutter, last cutter tooth peak (7) is aimed at down cutter tooth peak (10) and is pressed second ripple profile of tooth, and in this twice continuous die mould process, an end of material is in pan feeding under the free state all the time.Like this, in the time of can avoiding pull-shaped the distortion and break.When last mold pressing gestalt die sinking, the following cutter holder of living the corrugated plate that presses by the spring force while corrugated plate demoulding that resets.Like this, can press shape continuously, mould structure is simple, easy to operate, pressure shape is superior, size is accurate, shaping speed is fast, has remedied the shortcoming of rolling and monodentate die mould.

Claims

1, the horizontal tool of the bimodal moulding of a kind of corrugated plate, has upper and lower template, it is characterized in that: the cutter of upward living is supported by the spring in the cope match-plate pattern die, upper slitter with two tooth peaks, the position of at least one tooth peak height of cutter tooth alive peak on being lower than, fix with cope match-plate pattern, be slidingly matched between upper slitter and the cutter upward alive, cutter following alive with two tooth peaks, support by the spring in the lower bolster groove, following cutter tooth peak is fixed at the position and the lower bolster that are lower than at least one the tooth peak height of cutter tooth peak of living down, is slidingly matched between following cutter and the cutter down alive.
