Abstract
The utility model relates to a bend-forming device for the double-layer exhaust pipe of a motorcycle, which is a novel processing device provided for the production of the double-layer exhaust pipe of a motorcycle. The utility model has the advantages of simple structure and convenient manufacture, is composed of a combined mandrel, a sliding mould, a bend mould, and a corresponding oil feeding cylinder, and is last a pipe bender for one-step bend forming. The utility model not only changes the complex technology that a sand filling method or a freezing method is adopted to process the exhaust pipe for bend forming at present, but also omits yellow sand, or acetylene, or heating materials or refrigerating machinery and various complex special process and tool equipment. In the processing, the bending-molding device not only relieves the labor intensity of operators, but also raises work efficiency, being a national ideal bend-forming device for the double-layer exhaust pipe at present.
Description
The utility model relates to the pipe bending technique that uses axle, is a kind of processing unit (plant) of motor vehicles blast pipe, is specially adapted to process the air gap pipes of motorcycle, is the one step completed process unit of inside and outside bimetallic tube combination forming.It is mounted in and finishes its function on WA27Y-60 type bending machine or other the similar bending machine.
In China, the motorcycle air gap pipes are the new products that use in recent years.The inside and outside driving fit of the head of blast pipe has the equidistant gap of crescent, and keeps the precision such as circularity of inside and outside pipe between the other parts inner and outer pipes, surface transition also requires smoothly.The blast pipe bending radius is little, is difficult to moulding.Way commonly used at present is to adopt to irritate micromicrofarad and freezing.Irritate micromicrofarad and want Heating and Bending Formation, but also need yellow sand, second piece, heating raw etc.Also necessary technology and pattern assembly be must be equipped with in addition, batch or production in enormous quantities are not suitable for carrying out; Freezing rule needs special Refrigerating Machinery and various special process and frock, investment goods expense costliness, but also good special operational environment will be arranged, be not suitable for carrying out batch or production in enormous quantities equally.
The purpose of this utility model is the brake forming device of a kind of combination of design, has both improved complicated technology and pattern assembly, makes easy to operately, has reduced manufacturing cost again, improves productivity effect, adapts in batches or large batch of production.
The utility model is by design bending mould, sliding formwork, axle and wrinkle resistant block mechanism, and is installed in and finishes its function on the similar bending machine of WA27Y60 type bending machine or other model.
Of the present utility model simple in structure, low cost of manufacture can guarantee the precision of every technical indicator, suitablely carries out batch or large batch of production.
Accompanying drawing is a structure chart of the present utility model:
1 is the axle oil cylinder among the figure, the 2nd, and extension bar, the 3rd, workpiece, the 4th, axle, the 5th, wrinkle resistant, the 6th, bending mould, the 7th, clamping cylinder, the 8th, sliding formwork, the 9th, the sliding formwork restorer, the 10th, the sliding formwork seat, the 11st, sliding formwork is sent oil cylinder to.Bending mould 6 is a cylinder, and it and clamping cylinder 7 fuse, and gyration is done in both can go for a stroll centers of circle of bent mould 6, and workpiece 3 is installed in the gap between the pad of the cylindrical of bending mould 6 and clamping cylinder 7.Sliding formwork 8 and sliding formwork restorer 9 are to send to and reset by the effect that is located at spring in the restorer and voussoir.
Embodiment of the present utility model is as follows: axle oil cylinder 1 places the operating position by extension bar 2 with axle 4, the preparation of working well.Workpiece 3 is by the gap between the gap between bending mould 6 and the clamping cylinder 7 and sliding formwork 8 and wrinkle resistant 5, be placed on the operating position after, (this moment, clamping cylinder 7 was positioned at the below of sliding formwork 8), clamping cylinder 7 and sliding formwork restorer 9 are worked simultaneously, workpiece pressing 3.Bending mould 6 is being with clamping cylinder 7 to rotate together then, carries out the tube bending moulding.This moment, sliding formwork 8 was sent by sliding formwork to oil cylinder 11 is sent to and bending mould 6 synchronous working, to reduce sliding formwork 8 mobile working resistances.In order to prevent that wrinkle from appearring in pipe medial surface when the brake forming, add wrinkle resistant 5.Should be arranged to good quick condition for wrinkle resistant 5, just can make the smooth arc transition of tube surface.After completion of processing, bending mould 6 rotates back into the origin-location, and clamping cylinder 7 also returns to original position simultaneously.When unclamping clamping cylinder 7 and sliding formwork and sending oil cylinder 11 to, sliding formwork 8 is also simultaneously bounce back into original position by sliding formwork restorer 9.At this moment just can take out the workpiece that processes.The processing of next workpiece is carried out in Yi Shang work repeatedly again.End in the sliding formwork restorer is equipped with spring, and when workpiece is adding man-hour, sliding formwork 8 moves simultaneously with workpiece, and the spring in the sliding formwork restorer is compressed, and when sliding formwork and workpiece unclamped, the interior spring of sliding formwork restorer bounce back into the origin-location with sliding formwork.Axle 4 is built-up mandrels, is combined by major and minor axle.Main spindle stretches into interior pipe, the precision of pipe in ensureing.Main spindle is a filled circles axis of a cylinder; Secondary axle is eccentric crescent axle, and it can do corresponding the adjusting on main spindle, and the smooth transition with gap and crooked rear surface between the assurance inner and outer pipes plays wrinkle resistant effect simultaneously.Whole axle 4 is by the length of extension bar 2 adjusted turnover, is used for controlling the circularity and the surface flatness of the surfaces externally and internally of whole blast pipe moulding.
The relevant size of the bending mould 6 described in the utility model, sliding formwork 8, axle 4, wrinkle resistant 5 etc. is decided according to the requirement in blast pipe inner and outer diameter size and gap, so the utility model can be used for the differently curved moulding in the equidistant gap of air gap pipes of different specification size requirement.Bending mould 6, sliding formwork 8, wrinkle resistant 5, make of 45 steel, the most handy 40cr material is made.Axle 4 usefulness 38Cr MoAl materials are made.
The utility model is simple to operate.As long as mix corresponding electrical system, workpiece is placed on the brake forming that just can finish the equidistant gap of inner and outer pipes on the Working position, alleviated labor intensity of operating personnel greatly.Owing to do not use yellow sand, second piece, heating material etc., also needn't dispose other technology and pattern assembly, both saved the investment goods of various expense costlinesses, improved working environment again.The workpiece of processing can guarantee technology acuracies such as its curved surface is smooth, inner and outer pipes circularity, gap, has improved production efficiency again simultaneously, is applicable in batches or production in enormous quantities, is present domestic comparatively ideal air gap pipes brake forming device.
