The utility model discloses a kind of manual tube bender, comprises holder, outer washer, fast pulley, flat key, inner washer, fixed axis, switch block combination, movable axis, castor, locking pin, jackscrew, clamping seats, retainer block; Described fixed axis is arranged on holder centre bore, is fixed by locking pin; Fast pulley is integrally connected by flat key and fixed axis; Switch block combination is housed outside fast pulley, between switch block combination and fast pulley, is provided with inner washer; Outer washer is separated with in the middle of switch block combination and holder; Castor is fixed in switch block combination by movable axis, and castor can rotate around movable axis; Holder is equipped with respectively clamping seats and retainer block, clamping seats is provided with jackscrew.This manual tube bender ensure that the uniformity of handrail circular arc, meets the interchangeability requirement between workpiece, improves efficiency to a certain extent simultaneously, alleviates the labour intensity of workman, is particularly useful for batch production.
Description
Technical field
The utility model relates to a kind of bicycle production equipment field, particularly relates to a kind of manual tube bender.
Background technology
Stainless steel product is subject to the favor of people day by day with its excellent corrosion resistance, high temperature oxidation resistance and high/low temperature intensity, except a large amount of for except the industries such as decoration, light industry, residential hardware, cooking apparatus and apparatus, in bicycle pipe part, have also been obtained a large amount of application.
Bicycle type handrail, material is steel pipe Φ 25 x1.5/1Crl8Ni9.It is outside that bicycle type handrail is used for vehicle cover body, the quality making quality on the serviceability of car load without large impact, but for very important the outward appearance of product and installation procedure.Indeformable for ensureing bent tube section during bending tubing, most of producer adopts ancient bending method: make a model by bending internal diameter, filling sand in pipe, then it is slowly curved to comply with model; Also have one then not fill with sand, to bending pipes position local heat, make tubing generation plastic deformation slowly curved again.These 2 kinds of methods are all relatively backward, and working strength is large, and poor working environment, efficiency is also low.Two workmans coordinate processing, class can only process tens curved, and size also bad control, the deflection of workpiece is large, uniformity and interchangeability poor; Profile cannot meet the demands.
Summary of the invention
In order to overcome, existing bend pipe mode working strength is large, efficiency is low and the problem of uncontrollable size, the utility model provides a kind of manual tube bender, this manual tube bender ensure that the uniformity of handrail circular arc, meet the interchangeability requirement between workpiece, improve efficiency to a certain extent simultaneously, alleviate the labour intensity of workman, be particularly useful for batch production.
The utility model solves the technical scheme that its technical problem adopts: a kind of manual tube bender, comprises holder, outer washer, fast pulley, flat key, inner washer, fixed axis, switch block combination, movable axis, castor, locking pin, jackscrew, clamping seats, retainer block; Described fixed axis is arranged on holder centre bore, is fixed by locking pin; Fast pulley is integrally connected by flat key and fixed axis; Switch block combination is housed outside fast pulley, between switch block combination and fast pulley, is provided with inner washer; Outer washer is separated with in the middle of switch block combination and holder; Castor is fixed in switch block combination by movable axis, and castor can rotate around movable axis; Holder is equipped with respectively clamping seats and retainer block, clamping seats is provided with jackscrew.
The length at the handle place of described switch block combination suitably can lengthen or lengthen by adding auxiliary sleeve pipe, can increase the rotation arm of force like this, be beneficial to the muscle power of saving operator.
Described retainer block is v-shaped structure, is conducive to stability during workpiece blowing.
Described fast pulley and castor are arc structure, are beneficial to the profile ensureing bending pipe fitting.
The utility model, a kind of manual tube bender: first, taken out from switch block combination and castor by movable axis, be put in the arc groove of fast pulley by workpiece bending end, the other end is placed in the V-shaped groove of retainer block.Workpiece material length need according to the length of run blanking of workpiece, and the position on bending length direction can go out according to size calculated in advance, and makes a mark or locate on base.Then, be put into by driving wheel in switch block combination, and worn by movable axis in the hole of people's castor and switch block combination, return to the initialization position of Manual pipe bender by movable axis and castor, clamped position place is by jackscrew top tight workpiece.Now workpiece is in stationary state.Secondly, the handle of switch block of holding with a firm grip combination drives castor rotary motion together with movable axis, contrary with there being the direction of jackscrew, rotates 90 °.Now jackscrew termination top tight workpiece, the castor arc surface combined with switch block outside the circular arc of workpiece bending part is adjacent to, and the bending part of inner arc portion and the arc surface of fast pulley are adjacent to, and now Forging Process completes.Finally switch block combination is unclamped, take out movable axis and castor, workpiece is taken out.Motion in whole motion process between castor and workpiece is that rolling rubs and examines, and extends the life-span of castor.
A kind of manual tube bender of the utility model, its beneficial effect is:
1) use manual tube bender bend pipe steady, safe, efficient, easy to operate.
2) this is Manual structure, and structure is simple, and easy processing and manufacturing, only needs common steel plate, round steel material and standard lock bolt etc. to get final product processing and implementation.Major part frock special purpose parts all can be made by oneself, has saved cost, is easy to realize for medium-sized and small enterprises.
3) because the circular arc of castor and absorption surface need match with workpiece, therefore workpiece is different, and required fast pulley is not identical with the circular arc of castor yet, and the utility model realizes the function of a tractor serves several purposes by exchange fast pulley and castor.
