Summary of the invention
The utility model provides a kind of die head of sheet material machine, and is rational in infrastructure, and adjustment is flexibly and simply, Flow of Goods and Materials is steady, and discharging is even, and the technical scheme of employing is as follows:
The die head of sheet material machine of the present utility model, comprise upper die body, lower mold body, flow velocity adjusting device and mouthful die clearance adjusting device, mouth die clearance adjusting device comprises a yard iron and a mouthful die clearance guiding mechanism, runner extended region in the die head has a trigonum, and it is characterized in that: the angular range on the described die head longitudinal section between two back sides of this trigonum is 172 °～176 °.Such structure makes evenness of discharge better.
The angular range of trigonum is 20 °～25 ° on the described die head cross section, forms on upper die body, the lower mold body promptly that the angular range on cross section is 20 °～25 ° between two inwalls of this trigonum.Such structure is better in the expansion effect of width to material.
Described flow velocity adjusting device comprises locking nut, adjustment screw, spacing pressing plate, guiding pressing plate, choked flow rod and sealing strip, upper die body is provided with the choked flow rod and adjusts groove, the choked flow rod is located at the choked flow rod and adjusts in the groove, sealing strip is installed in choked flow rod both sides, the front end of adjustment screw and choked flow rod are threaded, the rear end is provided with locking nut, and locking nut is connected the outer wall of upper die body by spacing pressing plate and guiding pressing plate.By the size of flow velocity adjusting device adjustment cross section of fluid channel, adjust material flow, extremely all even suitable to adjust material at the flow velocity of width.
Described mouthful of die clearance guiding mechanism comprises differential bolt, square nut and hinged spiral shell head, and hinged spiral shell head is fixed on yard iron, and differential bolt front end is connected by fine thread with hinged spiral shell head, and the middle part is connected by coarse thread with square nut.By the difference of two sections pitch on the differential bolt, at same position die lip is carried out two-way small adjustment, make mouthful die clearance more even.
In order to reduce the fluctuation of discharging, guarantee the compactness of goods, the exit of die body inner flow passage is provided with dashpot and typing section, and between the inwall of dashpot and typing section and the vertical plane very little gradient is arranged all.
The utility model beneficial effect against existing technologies is, material the flow velocity of die width direction evenly, be easy to control, the pressure of die head is convenient to regulate, the compactness of goods is better, the adjustment of mouthful die clearance is more flexible, the discharging width is easy to change.
