Said back plate is a rectangular steel plate, and both sides have the bolt hole that links to each other with side plate, and for intensity that guarantees the back plate and the mode that reinforcement is generally adopted in weight reduction, back sheet material material generally also is a stainless steel;
Said lip plate is elasticity alloy steel material manufacturing preferably, and the bottom lip requires to be processed into higher linearity;
Said adjusting nut requires to have higher accuracy of thread, the gap during simultaneously for elimination adjusting nut and adjusting bolt up-down adjustment, and adjusting nut is provided with the device of eliminating the gap;
Said adjusting bolt also requires higher accuracy of thread, and the bottom links to each other with the lip plate, and will limit the rotation of regulating bolt on the structure;
The gauge outfit of said dial gauge contacts with the end face of regulating bolt, and the up-down adjustment amount of regulating bolt also is that the gap variable quantity between die head lip and the steel band can show through dial gauge intuitively.
Compared with prior art; Use this die head, gap adjustment is convenient and reliable, regulates data and intuitively shows; Can onlinely regulate at any time according to the condition of production; The transverse gage uniformity of make producing film is better controlled and is improved, thereby the mechanical performance of film also is increased, and makes the film of rolling tightr, smooth.
