Abstract
The invention relates to a module group device of pipe bender, belonging to the bending technology field of metal pipe, comprising machine head. On the machine head there are wheel module, anti-crease module and workpiece module clamp. Ring grooves are set at side face of wheel module on the peripheral direction. Straight grooves are set at inner side of the anti-crease module. Hydraulic assisted propulsion device is set on the machine head. The hydraulic assisted propulsion device comprises assisted propulsion cylinder. Assisted propulsion plate is set on the assisted propulsion cylinder and guide module is set on the assisted propulsion plate. Straight grooves are set on said guide module. In the technology project of invention, hydraulic assisted propulsion device is added in the module group device and as the hydraulic assisted propulsion device applies some pushing force to pipe fitting pulling force to elbow at the position of outer arc is decreased so that the condition that pipe wall at the position of outer arc of elbow is pulled thin is improved, abilities of bending thin-wall pipe and bending in small radius are strengthened, rupture in bending is prevented, and manufacturing quality of workpiece is improved.
Description
Technical field
The present invention relates to metal tube bending techniques field, relate in particular to a kind of die set that is used for bending machine.
Background technology
Common bending machine is in the process of bending pipes, when being about in the die set that pipe fitting places bending machine laggard line bend, the tube wall at elbow external arc position is easy to be drawn thin, serious also may be by drawing crack, to have a strong impact on the compressive property of workpiece like this, this phenomenon is especially obvious in stretch bending process.
Summary of the invention
The present invention is directed to the defective that prior art exists, its objective is provides a kind of tube wall that is used for reducing on the bending machine elbow external arc position to be drawn thin die set.
To achieve the above object, the present invention has adopted following technical scheme:
A kind of die set that is used for bending machine, comprise head, head is provided with wheel mould, crease-resistant mould, workpiece die clamp, wheel mould side is circumferentially with annular groove, is provided with straight trough in the inboard of crease-resistant mould, also is provided with the hydraulic pressure auxiliary propulsion plant on the head, described hydraulic pressure auxiliary propulsion plant comprises the auxiliary propulsion oil cylinder, the auxiliary propulsion oil cylinder is provided with the auxiliary propulsion plate, and the auxiliary propulsion plate is provided with guided mode, and described guided mode is provided with straight trough.
As preferably, described workpiece die clamp is inserted with the wheel mould by the clamping piece and is formed, and the clamping piece is provided with straight trough, and the wheel mould is inserted and is provided with straight trough, on the clamping piece straight trough with take turns mould and insert that upward the straight trough position is corresponding.
The present invention has adopted above-mentioned technical scheme, in the process of using bending machine bending metals straight tube, in die set, set up the hydraulic pressure auxiliary propulsion plant, promptly at the rear portion at the elbow external arc position of pipe fitting, apply certain thrust by the hydraulic pressure auxiliary propulsion plant to pipe fitting, reduce the suffered pulling force in elbow external arc position, thereby play the tube wall that improves elbow external arc position and draw fickle condition, strengthen the ability of machine bending light-wall pipe, minor radius bending, prevent that BENDING PROCESS from breaking, minimizing elbow external arc tube wall draws thin, improves the crudy of workpiece.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is made a detailed explanation:
Present embodiment is an example to make round straight tube bending.
A kind of die set that is used for bending machine, comprise head 8, transmission device 6, wheel mould 7, workpiece die clamp are housed on the head 8, wrinkle resistant mould 4, be processed with circular arc straight trough 101 on the clamping piece 10, the wheel mould is inserted and is processed with circular arc straight trough 91 on 9, and circular arc straight trough 91 is corresponding with circular arc straight trough 101 positions, wherein the workpiece die clamp by clamping piece 10 with take turns mould and insert and 9 form.
The described mould 7 of taking turns is connected by main shaft 11 with transmission device 6,7 runnings of transmission device 6 control wheel moulds, wheel mould 7 sides circumferentially are processed with circular arc annular groove 71, be provided with circular arc straight trough 41 in the inboard of crease-resistant mould 4, also be provided with the hydraulic pressure auxiliary propulsion plant on the head 8, described hydraulic pressure auxiliary propulsion plant comprises auxiliary propulsion oil cylinder 3, and auxiliary propulsion plate 1 is housed on the auxiliary propulsion oil cylinder 3, guided mode 2 is installed on the auxiliary propulsion plate 1, is processed with circular arc straight trough 21 on the described guided mode 2.
And the circular arc straight trough 91 in the present embodiment, circular arc straight trough 101, circular arc straight trough 41 and circular arc straight trough 21 are semicircle straight trough.Circular arc annular groove 71 is semicircle annular groove.
During work, clamping piece and the wheel mould clamping work pieces of inserting, the circular arc straight trough 41 that lays respectively at wrinkle resistant mould 4 and guided mode 2 and circular arc straight trough 21 just in time are in the outer wall of pipe fitting.
Start bending machine, then the circular arc straight trough 91 inserted on 9 of the circular arc straight trough on the clamping piece 10 101 and wheel mould just in time clamps pipe fitting.And pipe fitting one side is just in time carried out bending along the semi-round ring shape groove 71 of wheel mould 7, auxiliary propulsion oil cylinder 3 advances simultaneously, promoting auxiliary propulsion plate 1 advances with guided mode 2, the elbow external arc portion of pipe fitting was compressed and was advanced by guided mode 2 this moment, thereby alleviate the pulled condition at pipe fitting elbow external arc position in BENDING PROCESS, reduce elbow external arc position and drawn thin.
Technical scheme of the present invention can also be used to make multiple metal winding pipes such as oval bend pipe, square elbow.
