Description

A kind of carrying auxiliary bending mechanism of bending machine

Technical field

The utility model relates to material buckles equipment technical field, the carrying of specifically a kind of bending machine assists bending machine Structure.

Background technique

Direct rod shape or straight tube-like material are bent to reach corresponding requirement, construction, pipeline construction or It is often used in component of machine process, the material buckles of traditional technology, either metal or nonmetallic, is broadly divided into heat It is curved or two kinds of clod wash, the principle of hot bending be heat the material to can Free Transform degree, then be allowed to bend by external force, should Method is more demanding to material and heating medium, and ease for operation and safety be not high；Clod wash folding is not heated in material Under room temperature state, a kind of method bent by external force, this is also a kind of modern and common method for bending material, should Method is easy to operate, and the requirement to material is not also high, but under room temperature state, and force requirements needed for bending different materials are big, This would have to by means of complicated mechanical device with force requirements needed for meeting bending material.It is curved in current current material In folding technology, material buckles equipment or it is mechanical either use manpower or mechanical force, all there are problems that different defect and.

Notification number is that the utility model patent of CN205869152U discloses a kind of manual tube bender, passes through operation handle Driven wheel is driven by the center of circle of driving wheel, forces material to move between driving wheel and driven wheel, to realize material bending.This Kind produces frictional force using both feet as fulcrum, with ground using manually method existing defects, operator, while to manipulator The power forward or backward that handle applies has to be larger than the strength of material buckles, but both feet are to being limited with the frictional force that ground is formed , at this moment, fulcrum then becomes a factors of instability, so in this condition, which is unable to complete work, If the frictional force between both feet and ground can be enhanced to infinity, the body structure of the mankind is also unbearable and issues such Huge energy；

Notification number is that the utility model patent of CN206911990U discloses a kind of bending machine, is pushed by driving assembly Indent, extruding and two mobilizable slot rollings of the material by indent form bending condition, material are caused to bend.Such benefit Strength problem needed for although can solve bending with the mode of impersonal force, but exist using the method that driving assembly pushes indent and lack It falls into, indent is when pushing some hollow materials, due to foring between the outer wall of material stress side and the outer wall of resistance side Can be with the space of deformation, so such bending method will lead to material and be crowded flat rather than be bent, this will bring great material Material waste；

Notification number is that the Chinese utility model patent of CN206240991U discloses a kind of bending machine, passes through driving device Cooperate by material and mold cramping and with the guiding device simultaneously clamped on, using mechanical force automatically by material bending, and should Patent possesses the device of automatic push material.Such method does not have obvious shortcoming with material buckles technology sheet, but thus band The high maintenance cost come, high energy, huge equipment volume, when being also to the problems such as pollution and serious noise of environment Under the problem of must paying close attention to, China has advocated always energy-saving and environment-friendly idea of development since reform and opening-up, as so easily several meters Length and more than ten tons of weight " strange beast ", be not particularly suited for small-scale and environmentally friendly production concept instantly.For example, one Small sized personal workshop of the annual output less than hundred receives customization work by hand in the lane of curbside, while using 220 volts of civilian electricity Again in view of the influence that noise lives for neighbourhood, this is also " roadblock " put in face of most handicraftsman.

In addition, what most entrepreneurs wished to obtain is excellent under the call that China proposes " masses start an undertaking, millions of people are innovated " Matter, efficient and scalable technical solution, but pick out in the prior art most suitable, often meet A part of demand, but the drawbacks of have to receive this technology, the thought for abandoning starting an undertaking of finally having to.
