Abstract
The invention discloses a manufacturing method of a wheel spoke of an automobile, comprising the following steps of: carrying out blanking processing on a steel plate; carrying out front and back drawing processing on the blanked steel plate through a front and back combined type mould in one step; carrying out punching and forming processing; and finally carrying out air hole chamfering processing to manufacture the finished product of the wheel spoke. The invention carries out the front and back sequential drawing processing on the blanked steel plate by a hydraulic machine through the front and back combined type novel mould in one step on a same machine and omits original trimming and flanging processing processes, thereby decreasing the machining processes and the machining errors, reducing the production cost, enhancing the finished product ratio and the work efficiency and is especially suitable for producing various wheel spokes on a small scale.
Description
One, technical field
The present invention relates to a kind of manufacturing technology of automotive wheel, specifically relate to a kind of manufacture method of spoke of vehicle wheel.
Two, background technology
At present, most widely used wheel is a steel wheel on automobile, and it is generally formed, made respectively by wheel rim and spoke two parts, and then makes up, welds together.Wherein: the geometry of spoke is made up of mounting plane, easement curve section and direct section, is processed with centre bore and bolt hole on its mounting plane, and mounting plane uses bolt and automotive hub to be fixed together; Its straightway and wheel rim weld together; Its easement curve section plays the effect that is connected and installed plane and straightway, is processed with the wind hole on the easement curve section.The manufacture method of this wheel spoke (steps in sequence) is: steel plate cutting, just stretch, multiple working procedure (master operation as shown in Figure 3) such as reverse-drawing (being positive and negative twice stretching finishes by two hydraulic presses), moulding, punching side cut, flange, wind Hole chamfering, it is corresponding to many kinds, the small lot batch manufacture of spoke, exist the problem that operation is more, mismachining tolerance is bigger, improve production cost and working strength of workers, influenced yield rate and operating efficiency.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and the manufacture method of the wheel spoke that a kind of operation is few, mismachining tolerance is little is provided.
Purpose of the present invention realizes by following technical solution: a kind of manufacture method of wheel spoke is: at first steel plate is carried out blanking and handle, then, the steel plate after the blanking is carried out disposable positive and negative drawing by positive and negative mating type mould handle; Then, carry out punching, forming processes again; At last, make the wheel spoke finished product through the processing of wind Hole chamfering.
After adopting the present invention, new-type mould by positive and negative mating type, carry out positive and negative stretch processing successively and disposablely finish on the machine on the same stage by the steel plate of hydraulic press after blanking, and original side cut, flange treatment process have been omitted, thereby manufacturing procedure and mismachining tolerance have been reduced, reduce production cost, improved yield rate and operating efficiency.Be specially adapted to many kinds, the small lot batch manufacture of spoke.
Four, description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the main schematic flow sheet of the manufacture method of wheel spoke of the present invention.
The structural representation of the wheel spoke finished product that Fig. 2 makes for the present invention.
Fig. 3 is the main schematic flow sheet of the manufacture method of known wheel spoke.
Five, the specific embodiment
With reference to Fig. 1 as can be known, the manufacture method of wheel spoke of the present invention is: at first (pass through hydraulic press) to steel plate and carry out the blanking processing, then, the steel plate after the blanking is carried out disposable positive and negative drawing by positive and negative mating type mould handle; (by about 63 tonnage punch presses) carry out punching, (by about 400 tonnage hydraulic presses) forming processes (having contained the stirring inner edge handles) then, again; At last, make wheel spoke finished product (as shown in Figure 2) through the processing of wind Hole chamfering.
Wherein: the new-type mould of positive and negative mating type is that the design feature of comprehensive original positive drawing die and reverse-drawing mould is in one, and make by computer programming, and by about 400 tonnage hydraulic presses through the control (technical data is calculated accurately) of its microcomputer controller to the steel plate after the blanking carry out just stretching earlier, the machine on the same stage of back reverse-drawing, the disposable processing of same station, and contained side cut, the processing of stirring outside, so do not need to carry out again original side cut, flange treatment process.
As shown in Figure 3, the manufacture method of known wheel spoke (steps in sequence) comprising: steel plate cutting, just stretch, multiple working procedures such as (can abbreviate side cut as), flange, wind Hole chamfering are cut edge in reverse-drawing (being positive and negative twice stretching finishes by two hydraulic presses), moulding, punching.
Claims (2)
1. the manufacture method of a wheel spoke is characterized in that: at first steel plate is carried out blanking and handle, then, the steel plate after the blanking is carried out disposable positive and negative drawing by positive and negative mating type mould handle; Then, carry out punching, forming processes again; At last, make the wheel spoke finished product through the processing of wind Hole chamfering.
2. the manufacture method of wheel spoke as claimed in claim 1, it is characterized in that: described positive and negative mating type mould is the design feature that integrates original positive drawing die and reverse-drawing mould, and make by computer programming, and by hydraulic press through the control of its microcomputer controller steel plate after to blanking carry out just stretching earlier, the machine on the same stage of back reverse-drawing, the disposable processing of same station.
