Abstract
The invention relates to a bending forming method for a multi-segment bent pipe section, belongs to the technical field of bending forming and relates to inventions of clamping methods. The bending forming method is characterized in that through a clamping method, bending of a non-straight-line-segment bent pipe which cannot be bent on a pipe bending machine before is achieved on the pipe bending machine in the mode that the non-straight-line-segment bent pipe is clamped through a novel bending die. The specific bending forming method comprises the following steps that after bending of a first curve is achieved on the pipe bending machine through an original bending die, the novel bending die (a pipe bending die body and a clamping block) replaces the original bending die to clamp and bend the bent pipe. The bent pipe is placed in around cavity formed by the pipe bending die body and the clamping block of the novel bending die, the pipe bending die body and the clamping block of the novel bending die are closed to clamp the bent pipe under the action of external force. The pipe bending die body and the clamping block of the novel bending die are driven by torsion of a machine tool to rotate, and accordingly bending of the bent pipe is achieved. The bending forming method has the beneficial effects that the non-straight-line-segment bent pipe is clamped, and thus bending forming of the non-straight-line-segment bent pipe is achieved on the pipe bending machine.
Description
Technical field
The invention belongs to brake forming technical field, relate to the invention of new clamp method.
Background technology
Elbow curvature without straightway is molded, and pipe is under the involutory clamping force of bending die and fixture block, along with curved
The driving force of pipe machine, rotates centered by bending die axle center, causes tube bending to be molded.Because two bendings
Between there is no straightway, bending machine cannot clamp (clamping straightway), so can only take to add thermal flexure
Method
Summary of the invention
It is an object of the invention to: the bending and molding method of a kind of multistage bending tube section is provided, it is achieved that two bendings
Between without the clamping in the case of straightway, thus realize brake forming on bending machine.
The technical scheme is that
Thering is provided the bending and molding method of a kind of multistage bending tube section, the method is the curved end of fixed bending tube, and
The method that the straight tube end of bend pipe is curved shaping；
One end gripped by frock of bend pipe is Curved, i.e. this frock is to clamp bending pipe fitting
Frock；
This frock includes bending die and fixture block,
Bending die is a post cake, and the cross sectional shape of post cake is the shape of a hoof, i.e. cross sectional shape one end is arc-shaped；
The side of post cake has semi arch wire casing, wire casing linear for curve, and this curve is at arc-shaped cylinder partial
Linear for straight line；
Fixture block is the blocks adaptive with described bending die, and fixture block has semi arch wire casing, the semi arch of fixture block
The linear of wire casing is also curve, when bending die and fixture block are clamped together, and the semi arch wire casing synthesis on both sides
One complete bend pipe cavity, this bend pipe cavity can clamp one end with Curved of described bend pipe；
Concrete procedure of processing is: be first placed in the semi arch wire casing of bending die by the bending section of bend pipe, then will folder
Together with block grips with bending die, afterwards with the semi arch wire casing of the arc-shaped cylinder of bending die to bend pipe
Straight tube end roll, obtain having the pipe fitting of multistage bending.
The invention have the advantage that and provide without straightway elbow curvature clamp method, can not at clamping straightway
Meeting clamp method during clamping action, this inventive method ensure that chucking power when gripping section is shorter, and then
Ensure that and bend on bending machine without straightway bend pipe, having reached dimensional requirement and the function of product, mould is tied
Structure is simple, and method is simple, used by different types of machines similar products.

Frock；
This frock includes bending die 2 and fixture block 3；
Bending die is a post cake, and the cross sectional shape of post cake is the shape of a hoof, i.e. cross sectional shape one end is arc-shaped；
The side of post cake has semi arch wire casing, wire casing linear for curve, and this curve is at arc-shaped cylinder partial
Linear for straight line；
Fixture block is the blocks adaptive with described bending die, and fixture block has semi arch wire casing, the semi arch of fixture block
The linear of wire casing is also curve, when bending die and fixture block are clamped together, and the semi arch wire casing synthesis on both sides
One complete bend pipe cavity, this bend pipe cavity can clamp one end with Curved of described bend pipe；
Concrete procedure of processing is: be first placed in the semi arch wire casing of bending die by the bending section of bend pipe, then will folder
Together with block grips with bending die, afterwards with the semi arch wire casing of the arc-shaped cylinder of bending die to bend pipe
Straight tube end roll, obtain having the pipe fitting of multistage bending.
