Double roll adjusting device of flat forming equipment

Abstract

The invention discloses a double roll adjusting device of flat forming equipment, which comprises a die head body, a first roll, a second roll and a roll driving mechanism. A material blank is discharged through a discharge hole of the die head body; the first roll and the second roll are arranged below the die head body and on two sides of the discharge material blank; the roll driving mechanism is used for adjusting the distance between the first roll and the second roll, and further adjusting the thickness of the material blank; and the outer surface of the first roll and / or the outer surface of the second roll form(s) die(s) which ensure(s) that the discharge material blank forms a set shape when the die(s) contact(s) with the discharge material blank. The flat forming equipment can manufacture products, such as automobile oil tanks with inserts embedded internally, and the like, has a simple structure, is convenient to machine, and has high efficiency and good product property. Meanwhile, the double roll adjusting device can adjust discharge thicknesses of flat material blanks from the upper part to the lower part, so that the discharge thicknesses of material blanks are uniform.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to flat forming equipment, in particular to a double cylinder adjusting device of flat forming equipment. Background technique [0002] The existing blow molding machine mainly includes a frame, an extrusion mechanism, a die head, a mold clamping mechanism, and a blowing mechanism. Its working method is: after the liquid plastic is sprayed out, the plastic body is blown onto A mold cavity of a certain shape is made into a product. The plastic is melted and extruded quantitatively in the screw extruder, then formed by laminating the film, and then cooled by blowing through the air ring, and then pulled by a tractor at a certain speed, and wound into a roll by a winder. [0003] The interior of the molded product blown by the existing blow molding machine is usually empty. If an insert is required inside, such as an automobile fuel tank, a hollow automobile fuel tank shell...

AI Technical Summary

Problems solved by technology

Although this solution solves the problem of product tightness and complex processing process, because this solution requires two die heads and corresponding die head control mechanisms, or leads two slabs from the same die head, the equipment structure is complicated and the control is difficult. Big

[0005] In addition, when the die head device of the existing blow molding machine is discharging, when the flat-shaped blank is discharged from the top to the bottom, due to factors such as its own weight, the blank will sag and the thickness will be uneven.
