For realizing above purpose, the utility model C type beam obliquely amputates mould for 45 ° and comprises top board, locating piece, dynamic model, cover half, base plate, fixed head, regulating block and adjustable plate, described dynamic model is the moving platen that four angles are 45 ° of inclined-planes, stamping surface is its ramp, and the moving platen activity is embedded in cover half and the locating piece; Totally three triangular in shape of locating piece, it is fixed on three angles of cover half separately, and wherein corresponding with moving platen lower inclined plane locating piece is provided with the dynamic model back-moving spring; The regulating block that a plurality of adjustment screw are housed is fixed by bolts on top board and the base plate, is provided with adjustable plate between regulating block and the dynamic model, adjusts adjustable plate by the adjustment screw of adjusting on the regulating block, and dynamic model is moved freely in cover half and location-plate and adjustable plate; Corresponding dynamic model stamping surface place has the square hole that makes the turnover of punch press drift on the top board; Two fixed heads are separately fixed on cover half and the regulating block side end face, by top board, base plate, locating piece and fixed head cover half are fixed; Leave the elastic gap of size between dynamic model baseplane and the base plate greater than C type cantilever thickness; Moving platen, solid plate and adjustable plate are provided with the charging aperture that is 45 ° of angles with template.

Above-mentioned mould structure design has following characteristics:

1, on dynamic model innovative design 45 ° oblique impact pressure surface, when being moved downward, stamping press P produces a component F with the axial direction at 45 of C type beam along the oblique impact pressure surface, utilize 45 ° of direction component F that C type beam is cut sth. askew and cut, solved the former difficult problem that can't use 45 ° of angled end-faces of mould stamping-out C type beam.

2, on moving platen, solid plate, adjustable plate, designed the feeding port that is 45 ° of angles with template, make C type beam when feed direction is sent to, under the effect of punching shear, can keep high accurate 45 ° of oblique impacts to cut out, make two sections C type beams after the cut-out need not to repair the assembling (90 °) that just can realize high accuracy, fully guaranteed the perpendicularity of C type beam framework by instructions for use.

3, designed the moving platen that four angles are 45 ° of inclined-planes, and be embedded in solid plate and the locating piece in the mode of activity; Designed automatic reset device, dynamic model is moved downward under the effect of blanking pressure P, C type beam has been carried out oblique stamping-out, and when finishing stamping-out, reset fast automatically.That whole design has realized is laborsaving to C type beam, save time, the stamping-out of low energy consumption, and mould structure is simple, reasonable in design.

4, designed the adjusting device of forming by adjustable plate, regulating block and adjustment screw, moving platen regulated by adjusting adjustment screw, make moving platen in adjustable plate and solid plate stamping-out, reset freely, guarantee that the stamping-out of C type beam is smooth and easy, not stuck.

Adopt the C type beam of said structure to obliquely amputate mould for 45 °, can realize that C type beam and length direction are that 45 ° end face is disposable fast, height precisely, obliquely amputate efficiently, thereby when improving C type beam quadra product assembly precision, energy consumption and spillage of material have been reduced, and pollution-free, and improved operating efficiency greatly.
