Abstract
The present invention discloses a multistation cold-heading forming method of liner for automobile. Said method includes the following steps: (1), shearing material; (2), upsetting material and heading internal chamfer angle in one end; (3), turning material and heading internal chamfer angle in another end; (4), heading counterbore in internal chamfer angle position of one end; (5), turning material and heading counterbore in internal chamfer angle position of another end; (6), heading the counterbores of two ends of said material into through hole; and (7), forming.
Description
Technical field
The present invention relates to the cold-heading technology, specifically is a kind of automobile bushing multi-station cold-upsetting shaping technology.
Background technology
Existing automobile bushing all adopts turning processing, and not only operation is various, and difficulty of processing is big, and efficient is low, and cut material weight and almost be equal to product weight after the moulding, the raw material significant wastage, cost is higher, and quality can not guarantee.
Present cold-heading process technology is mainly used in five metals standard component processing such as nut, adopts the moulding of cold headers punching press blank, and technology is comparatively simple.Still there is not the cold-heading technology to be used for the technology report of automobile lining processing.
Summary of the invention
For solving the deficiency that above Vehicle Processing automobile bushing technology exists, the invention provides a kind of automobile bushing multi-station cold-upsetting shaping method, save blank, reduce cost, improve the quality of products and production efficiency.
The technical scheme that the present invention is taked for its purpose of realization is as follows:
Automobile bushing multi-station cold-upsetting shaping method is characterized in that may further comprise the steps: (1), cut material (generally according to the customer requirement material); (2), material is upset and is equalled chamfering in the also end rammer; (3), chamfering in the other end is upset is expected in upset; (4), at one end interior chamfer site rammer counterbore; (5), chamfer site rammer counterbore in the other end is expected in upset; (6), the counterbore that will expect two ends is upset into through hole; (7), utilize the die rod location of upsetting, will expect extrusion modling from the material both sides with the mould of setting cavity shape.
Cold extrusion is a kind of plastic working technique, and it makes metal volume make plastic transfer under the prerequisite of not destroying metalline, reaches few cutting, does not have cutting and make metal forming.The a large amount of metal debris that form when so just having avoided machining are saved iron and steel and various metal material in a large number.
The beneficial effect of technology of the present invention: traditional turning processing automobile lining, cutting stock weight is far longer than product weight, and cold-heading of the present invention is cut material weight and almost is equal to product weight after the moulding, less waste material even do not have waste material, economical with materials has reduced cost.Cold-heading makes metal material produce plastic deformation in addition, and the metal inside tissue is changed, and has improved mechanical performance of products, has guaranteed product quality.Adopt cold upsetting production, speed is fast, precision height, production efficiency height.
Description of drawings
Fig. 1 is a schematic diagram of fabrication technology of the present invention.(is example with Shanghai 055 neck bush)
The specific embodiment
Referring to accompanying drawing 1.
Figure 1 shows that cold heading technique processes the process of 055 neck bush (unit for millimeter):
(1), cuts material (being generally the customer requirement material); (2), material is upset and is equalled chamfering in the also end rammer; (3), chamfering in the other end is upset is expected in upset; (4), at one end interior chamfer site rammer counterbore; (5), chamfer site rammer counterbore in the other end is expected in upset; (6), the counterbore that will expect two ends is upset into through hole; (7), utilize the die rod location of upsetting, will expect extrusion modling from the material both sides with the mould of setting cavity shape.
Claims (1)
1, automobile bushing multi-station cold-upsetting shaping method is characterized in that may further comprise the steps: (1), cut material; (2), material is upset and is equalled chamfering in the also end rammer; (3), chamfering in the other end is upset is expected in upset; (4), at one end interior chamfer site rammer counterbore; (5), chamfer site rammer counterbore in the other end is expected in upset; (6), the counterbore that will expect two ends is upset into through hole; (7), utilize the die rod location of upsetting, will expect extrusion modling from the material both sides with the mould of setting cavity shape.
