Detailed description of the invention

Be further described below in conjunction with the bar folder of drawings and Examples to replaceable bending wheels of the present invention.

A bar folder for replaceable bending wheels is U-shaped U-tube material for the flat sheet of strip being bent into cross section.Comprise charging guide portion, kink and cutting part.As shown in Figure 1, concrete, charging guide portion fixes the charging aperture place of outer kink, and for the direction of fixing sheet material to be processed, cutting part is then arranged on the discharge outlet of kink, for cutting the sheet material after being bent according to the length-specific preset.

As shown in Figures 2 and 3, charging guide portion comprises guiding substrate and guide pulley.Guide substrate to be fixedly connected with the charging aperture of kink, it is the platform of a surfacing, and platform place plane is corresponding with charging aperture, makes material to be processed can enter charging aperture smoothly.Guide pulley then arranges and guides in substrate, its axle center with guide the plane orthogonal at substrate place and be connected with guiding substrate.Guide pulley can carry out System of Rotating about Fixed Axis with its axle center.The wheel face of guide pulley has around himself annular groove of one week, this annular groove thickness and sheet material to be processed match.In order to treat machining sheet location better, guide pulley is arranged in the guiding substrate at sheet material both sides of the edge place, coordinated by multiple guide pulley simultaneously, the both sides of sheet material are clamped, when sheet material to be processed moves to kink, guide pulley rotates thereupon, and the basis of firm clamping can not increase again the frictional force between guide pulley and sheet material.

In another embodiment, as shown in Figure 4 and Figure 5, in order to the sheet material to be processed of adaptive different size, guiding substrate is provided with the guide pulley fixed mount perpendicular to charging aperture plane in charging aperture both sides, pulley fixed frame is provided with some connecting holes, one screw rod being parallel to guiding base plane is connected with this connecting hole by nut, and screw rod is then connected with the axle center of guide pulley near the end of sheet material to be processed.By the connection of nut and screw rod, according to different sheet material to be processed, distance between guide pulley can be adjusted, with the sheet material to be processed of adaptive all size.

As shown in figures 1 to 6, kink is a strip bending mechanism, comprises strip lathe, multiple bending wheels, and the drive motors driving bending wheels to rotate.Concrete, lathe is provided with the wheels fixed part of multiple fixing bending wheels in pairs, and paired wheels fixed part is parallel to each other, and it is respectively arranged with corresponding bending axle hole, and this bending axle hole is used for the bending wheel bearing of fixing bending wheels.Bend wheels and then comprise bending wheel and lower bending wheel, the wheel face of described upper bending wheels and described lower bending wheels is tangent, the wheel of lower bending wheel faces its axis direction depression, wheel face then its axis direction projection dorsad of upper bending wheel, corresponding upper bending wheel and the wheel face of lower bending wheel can be fitted just.In other embodiments, shown in Fig. 7, upper bending wheels can be the smooth wheels that thickness is identical with U-tube road bottom width after bending.In order to make shaping U-tube material more accurate, along feedstock direction multiple bending wheels projection or depression angle strengthen gradually, sheet material to be processed is under the drive of bending wheels rotation, move to discharging opening gradually, its both sides are also gradually turned up under the effect of bending wheels simultaneously, finally become U-shaped.

In preferred embodiment, as shown in Figure 8, lathe two sides are provided with the embedded groove be connected with wheels fixed part, embedded groove is a square breach, after wheels fixed part embeds embedded groove, one fixed strip is being set in the porch of embedded groove, the entrance of embedded groove is being closed, wheels fixed part is securely fixed in embedded groove.This demountable structure can need to change bending wheels according to different designs, reaches different bending objects.
