Abstract

The utility model discloses a die for continuously bending a pipe for a pipe bending machine. The die comprises an upper die body, a clamping plate, a lower die body, a curved clamping block and an eccentric shaft module, wherein two ends of the upper die body are provided with arc notches; one end of the curved clamping block is provided with an arc notch; the upper die body and the lower die body are connected through the clamping plate; the curved clamping block is movably connected to the clamping plate; the clamping plate is fixed on the eccentric shaft module; and the eccentric shaft module is fixed on a pipe bending machine body. When the pipe bending machine for the die is used, pipes with continuous bends can be bent.

Description

A kind of bending machine is with the mould of continuous bend pipe

Technical field

The utility model relates to the plant equipment field, and particularly a kind of bending machine is with the mould of continuous bend pipe.

Background technology

Bending machine as its name suggests, a kind ofly exactly is bent into the machine of different cambers with pipe fitting, and it mainly comprises pipe fitting pusher and swan neck system.Bending machine utilizes the pipe fitting pusher that the pipe fitting of pre-bending pipe is delivered to the terminal swan neck system of board with track, is provided with the bend pipe mould that can pipe fitting be bent into the Different Diameter distance in the swan neck system.But the bend pipe mould that uses now generally all is made up of bend pipe die body 1 and clamp 2; Bend pipe die body 1 and clamp 2 have a circular arc recess on each and are used for fixing pipe fitting, and bend pipe die body 1 and clamp 2 are individually fixed in the diverse location of bending machine fuselage, and the notch end of the two is relative; Like Fig. 1, shown in 2; Owing to receive the spacing influence of clamp, when bending pipe fitting, when rotating to certain angle; Pipe fitting can stop and collision with clamp each other, so the bending machine of the type can't bend the pipe fitting that has continuous elbow and the crooked straight section elbow less than 110mm.

The utility model content

The purpose of the utility model just is the deficiency to prior art, and a kind of bend pipe mould that can bend continuous elbow is provided.

To achieve these goals; The technical scheme that the utility model adopts is such: a kind of bending machine is with the mould of continuous bend pipe; It is characterized in that: comprise upper die body, clamping plate, lower mold body, curve clamp and eccentric shaft module, respectively there is a circular arc recess at the upper die body two ends, and curve clamp one end has the circular arc recess; Clamping plate couple together upper die body and lower mold body; The curve clamp is movably connected on the clamping plate, and clamping plate are fixed on the eccentric shaft module, and the eccentric shaft module is fixed in the bending machine fuselage.

Compared with prior art; The utility model is fixed in the bending machine fuselage through the eccentric shaft module; The curve clamp is movably connected on the clamping plate; Pipe fitting and clamp stops and collides that movable simultaneously curve clamp can guarantee that elbow can normally take off after bending completion when having avoided bending continuous elbow again.

The specific embodiment

For purpose, technical scheme and the beneficial effect that is expressly understood the utility model more, below in conjunction with accompanying drawing the utility model is done further explanation, but the protection domain of the utility model is not limited in following examples.

Referring to Fig. 3, Fig. 4, a kind of bending machine of the utility model comprises upper die body 3, clamping plate 4, lower mold body 5, curve clamp 6 and eccentric shaft module 7 with the mould of continuous bend pipe; Respectively there is a circular arc recess 9 at upper die body 1 two ends; Curve clamp 6 one ends have circular arc recess 9, and clamping plate 4 couple together upper die body 3 and lower mold body 5, and curve clamp 6 is movably connected on the clamping plate 4; Clamping plate 4 are fixed on the eccentric shaft module 7, and eccentric shaft module 7 is fixed in the bending machine fuselage.

During use; Bending machine utilizes the pipe fitting pusher that circular arc recess 9 places of upper die body 3 are delivered at the pre-bending system position of pipe fitting 8, and the circular arc recess 9 of curve clamp 6 is fixing with pipe fitting 8, then along with the rotation of mould; Pipe fitting 8 is bent into certain camber; The pipe fitting pusher begins to push another again and bends the position and begin to bend then, so just can form the pipe fitting that has continuous elbow, treat that pipe fitting bends after; Curve clamp 6 can take off from clamping plate 4, and pipe fitting just can take off from mould normally.The utility model is fixed in the bending machine fuselage through the eccentric shaft module, and pipe fitting and clamp stops and collide when having avoided bending continuous elbow again.

Claims

1. a bending machine is with the mould of continuous bend pipe; It is characterized in that: comprise upper die body, clamping plate, lower mold body, curve clamp and eccentric shaft module, respectively there is a circular arc recess at the upper die body two ends, and curve clamp one end has the circular arc recess; Clamping plate couple together upper die body and lower mold body; The curve clamp is movably connected on the clamping plate, and clamping plate are fixed on the eccentric shaft module, and the eccentric shaft module is fixed in the bending machine fuselage.
