C shape part in the above-mentioned plastic-steel door and window handware, the moulding of its C shape section can be adopted the method for roll forming, utilize roller head machine that the band steel of 0.8 millimeters thick is vertical along it, from the dual-side ecto-entad progressively the roll extrusion bending forming be C shape section, its folding line place all will be bent into 90 °, and this is a kind of good method, but because the inner face pressurized, the outside tension has the deficiency that is easy to generate crackle.Also there are not solution to this problem and device at present.
Summary of the invention
The objective of the invention is to provide the forming method and the device thereof of C shape part in a kind of plastic-steel door and window handware, make the level and smooth flawless in folding line place of its C shape section.
For achieving the above object, solution of the present invention is: the forming method of C shape part in a kind of plastic-steel door and window handware, be that to utilize its device be the several to format roll of continuous forming machine, progressively longitudinally with the raw band steel of C shape part, outside in the roll extrusion bending forming is a C shape section, it is characterized in that: before the raw band steel roll extrusion bending forming of C shape part, carry out impression earlier, promptly along C shape part raw band steel vertically, the folding line A of C shape part, the last extrusion earlier of the B degree of depth is the 0.1-0.3 millimeter, width is the indenture of 0.5-2 millimeter, and then along its folding line A, B progressively roll extrusion bending forming is a C shape section.
A kind of device of realizing above-mentioned C shape part forming method, promptly continuous forming machine comprises fuselage, band steel guider and several to continuously shaped roller, it is characterized in that: the several of this continuous forming machine also are provided with impression device to continuously shaped roller front portion.
Described impression device comprises pressure roller and goes up roll shaft, lower compression roller and lower roller shaft thereof.
The described circumference of going up pressure roller is provided with and the corresponding impression cutter of C shape part folding line, and the body of roll of its lower compression roller is a plain-barreled roll.
The top of described impression cutter is tip-angled shape.
The both sides of the described lower compression roller body of roll are provided with boss, and the width of the raw band steel that its both sides boss spacing and C shape part are predetermined adapts, and the both sides end face of this boss upper inner and last pressure roller matches.
After adopting such scheme, the present invention compared with prior art has following beneficial effect: owing to the forming method and the device thereof of C shape part in the plastic-steel door and window handware of the present invention, before the roll extrusion bending forming, raw band steel to C shape part carries out indentation process earlier, progressively the roll extrusion bending forming is a C shape section again, this forming method, be folding line A along C shape part raw band steel with impression, B carries out the roll extrusion bending forming, the excess metal of corner during its bending, just offset and can not crack with impression, obviously have the roll extrusion of being convenient to bending forming and realize the level and smooth flawless effect in its folding line place.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
