Abstract

The utility model relates to an improvement to a hull used section bar rib cold bending machine, especially an edge bending prevention apparatus used in section bar bending process. The apparatus includes a middle frame, an upper-middle chuck, an upper-middle bending mould, a lower-middle bending mould and a rear bending mould; and is characterized in that: a combined cushion block is mounted between the middle frame and the right side of the lower-middle bending mould; the combined cushion block has two side pedestals each is mounted with a fixing bolt; the two side pedestals are symmetrically mounted between the middle frame and the right side of the lower bending mould; a middle pedestal is mounted between the two side pedestals by the two fixing bolts; a height adjusting hard cushion block is mounted in the groove of the middle pedestal. The utility model solves the problems of edge deformation, i.e. bending down, and low operating efficiency existing in current rib cold bending machine when machining section bars with asymmetrical section; and is mainly used for improving a rib cold bending machine.

Description

The anti-bevelling device of shape bending processing

Technical field: the utility model relates to the improvement of hull with the section bar cold-frame bender, is the anti-bevelling device of a kind of shape bending processing.

(2). background technology: the bending machining of ship hull structure use section bar and profile shapes, prior art is to adopt cold-frame bender to finish processing, add man-hour in the clod wash of carrying out asymmetry cross section section bar and profile shapes blank, the bevelling phenomenon usually takes place easily, be that the fabircated shapes blank at the vertical in-plane of processing flexure plane harmful downward bevelling distortion has taken place, the workpiece of completion need carry out secondary and proofread and correct processing, the inefficiency of Bending Processing.

(3). summary of the invention: the purpose of this utility model will solve existing cold-frame bender exactly and add existing downward bevelling distortion in man-hour and ineffective problem carrying out the section bar clod wash of asymmetry cross section, provides a kind of shape bending processing anti-bevelling device.

Concrete scheme of the present utility model is: the anti-bevelling device of a kind of shape bending processing, it has mid frame, above mid frame, be furnished with middle upper grip, bending die in below middle upper grip, being equipped with, on mid frame is arranged in bending die below down bending die is installed, on mid frame is arranged in bending die and down the right side of bending die the back bending die is installed; It is characterized in that: mid frame and in down the bending die right side between combined pad is installed, described combined pad has two side group seats, on each side group seat set bolt is installed all, described two side group seat symmetries be installed in mid frame and in down between the bending die right side, in the middle of two side group seats, adopt two set bolts to be connected and installed with middle pedestal; Pedestal is provided with groove in described, is furnished with two screws on the groove, and Height Adjustment hard cushion block is installed in the groove of middle pedestal, and described Height Adjustment hard cushion block is to adopt two screws to be connected with two screws on the middle pedestal.

Operation principle of the present utility model is (seeing Fig. 1 for details): in the slit under during upward bending die 2 reached during processed section bar blank 5 was placed between the bending die 3, the side of blank 5 is solid by back bending die 6 tops, and the lower edge of blank 5 sides is solid by the utility model supporting top; When cold-frame bender carries out bending machining to blank 5, blank 5 is out of shape because of the internal stress effect that is subjected to the asymmetry cross section tends to bevelling downwards, the bearing reaction effect that the utility model makes progress to the lower edge of blank 5 sides, two mutual balances of active force have been eliminated blank 5 downward bevellings and have been out of shape.

The utility model is compared with existing cold-frame bender, the utility model adds man-hour carrying out the section bar blank clod wash of asymmetry cross section, the internal stress that the effective balance section bar bending machining of energy is produced, eliminate the bevelling distortion that shape bending processing is produced, omitted the correcting process after shape bending is processed; The utility model is simple in structure, stable performance and cheap; The utility model preferably resolves existing cold-frame bender and adds existing downward bevelling distortion in man-hour and ineffective problem carrying out the section bar clod wash of asymmetry cross section.
