Description

A kind of bending structure for folding handle thin-wall tube

Technical field

A kind of bending structure is the utility model is related to, the small spacing of various thin-wall tubes, smaller part especially suitable for two device pipelines Bending on footpath.

Background technology

In evaporator, condenser production process, there is many that the work pipe behind product will be carried out to bending so as to refrigerator Assembling.In pipe bending process living, we frequently encounter the small spacing of thin-wall tube, minor radius bending.Thin-wall tube bending, it is easy to make Flat, dog leg is rolled over into pipeline, takes the problems such as difficulty living, therefore we carry out imposed deformation bending using sheave and deformation wheel, it is ensured that Bending part pipeline is full after bending, flat, the dog leg phenomenon of no folding；But when running into minor radius, small spacing bending, due to deformation wheel Spacing is smaller between sheave, all, so pipe living is difficult to take out, pulls up pin so we use in 1mm or so mostly and takes Lower deformation wheel carries out taking work, is loaded on deformation wheel after taking out workpiece and pin carries out bending.

The above, although can solve the problems, such as bending, take living, can not still meet our production requirement, people at present Work is manually operated, and unstability factor is excessive, and homogeneity of product is bad, and scrappage is high；Manual operation, act frequently complicated, labor Fatigue resistance is high, production efficiency is very low, since spacing is smaller generally in 1mm or so, bending process between two bending wheels Put pipe, take pipe difficult, especially bending angle takes pipe more difficult, the bending more than 180 ° is basic when between 90 ° to 180 ° It cannot take out, therefore, we are badly in need of, and a kind of effect is preferably a kind of to fold handle thin-wall tube bending structure.

The content of the invention

The task of the utility model is to propose a kind of reduction labor intensity, reduce operation, improve precision and production efficiency A kind of bending structure for folding handle thin-wall tube.

The task of the utility model, which is done in such a way that, is characterized in that：Fixed plate is as benchmark, described fixed plate one end The axis hole of process and assemble axis, one end of axis are penetrated in axis hole, the exposed fixed plate of the other end of axis, are bumped on this one end of exposed axis Fixed wheel, is screwed, and a threaded hole is respectively machined with the fixed wheel and fixed plate, and the bottom of fixed plate loads cushion block, pad Load locating piece below block, packing ring is loaded below the locating piece, and fixation, institute are connected with screw by reversing screw State handle both ends and be machined with bearing hole, bearing is bumped into the bearing hole, the torsion of assembling long slab handle is machined with the plate face of plate handle Turn screw hole, the other end of the plate handle penetrates axis bottom by bearing, and the bearing bottom surface is turned round with axis bottom weight merga pass Turn screw and fixation is connected with Screw, one end of long slab handle is in flush, and another termination is half-arc groove, and the long slab is nearly semicircle This one end of arc groove is machined with groove, and switch block is housed in groove, deformation wheel is housed on the switch block axis and is connected by screw fixation.Institute State equipped with screw is reversed in the plate face screw hole of long slab handle, the root for reversing screw penetrates small washer, small washer with above Long slab overlaps bottom surface, is overlapped by the bottom surface of the small washer with bearing inner race, and be fixed by screw.Rotate long slab handle When, half-arc groove is just stuck in the outer peripheral wall of axis, with the concentric long slab of overlapping of axles free opening and closing, and can be with 270 Spend left rotation and right rotation.The distance between the deformation wheel and fixed wheel at least 1mm, the distance between deformation wheel and screw at least 0.1mm.

The utility model has the following effects that：The technical program not only increases the quality, precision, work efficiency of product, Also significantly solve the problem of efficiency is low, complicated, labor intensity is big.

Embodiment

The technical program is to be worked in coordination to complete bending by long handle 1, handle 6, fixed plate 15, and such as Fig. 1 is embodied Shown, the fixed plate 15 is used as benchmark, and described fixed plate one end is machined with the axis hole of assembled shaft 9, and one end of axis penetrates axis hole In, the exposed fixed plate 15 of the other end of axis, is bumped into fixed wheel 8 on this one end of exposed axis, is fixed with screw 4-7,8 He of fixed wheel A threaded hole is respectively machined with fixed plate, screw 4-18 is threaded into being locked in hole and prevents from loosening, the bottom of fixed plate Load cushion block 12, locating piece 11 is loaded below cushion block, packing ring 13 is loaded below the locating piece and by reversing screw 2 Fixation is connected with screw 4-14.

6 both ends of handle are machined with bearing hole 20（As shown in Figure 4）, bearing 10 is bumped into the bearing hole, and plate is 1 Assembling long slab is machined with plate face 1 torsion screw hole 2, furtherly, torsion screw 2 assembles its root with screw hole and penetrates Small washer 16, small washer overlap 1 bottom surface with long slab above, and the bottom surface of the small washer is overlapped with 10 inner ring of bearing, passes through torsion Turn screw and Screw 17 is fixed, 6 other end is penetrated 9 bottom of axis, 10 bottom of bearing by the plate by bearing 10 Face reverses screw with 9 bottom of axis weight merga pass and Screw 7-19 is connected fixation.

The long slab is to be put into workpiece 1 opening, long slab 1 one end in flush, another termination is half-arc groove, mesh Be rotate long slab when, half-arc groove is just stuck in the outer peripheral wall of axis, concentric with overlapping of axles（As shown in Figure 2）, long slab Can freely open and close and can be with 270 degree of left rotation and right rotations, the long slab processes this one end of neighbouring half-arc groove There is groove, groove is interior to be equipped with switch block 5, is fixed on 5 axis of switch block equipped with deformation wheel 3 and by the connection of screw 4, the deformation wheel is with determining Take turns the distance between 8 at least 1mm or so, the distance between deformation wheel 3 and screw 4 at least 0.1mm.

The purpose of the Design Orientation block, first, bending angle is adjusted, second, can position.

When bending works, long slab is rotated 1, long slab is opened 1, is put into workpiece, then rotates long slab handle with plate 6 weights Close, long slab, which is stuck in the half-arc groove on 1 on axis, after coincidence overlaps and with one heart, then rotates long slab 1, plate 6 follow into Row rotates, and after rotational positioning, workpiece is stuck in groove and is rotated around screw 4 by fixed wheel 8 and deformation wheel, and its purpose is to prevent from forcing Pipeline bending is deformed, after bending folds to position, is positioned by locating piece, completes bending, long slab is rotated and is opened 1, take out workpiece.

The utility model not only solves small thin-walled tube spacing, and the difficulty of minor radius bending, also solves and let live, take difficulty living The problems such as, the quality of product is not only increased, also significantly solves the problem of efficiency is low, complicated, labor intensity is big.
