Abstract
Main points for manufacturing a thin-long complex-shaped metal piece are as follows: complex-shaped product to be made, such as portion with cavity of complicated form, adopts the precision casting method for formation, then it is butt-jointed with a metal blank to be made into a thin-long portion, the said blank is further die-forged into desired form, and finally the metal piece is edge-cut and polished. This method can reduce production cost by a great extent under the condition of ensuring product quality
Description
The invention belongs to a kind of technological method for processing of hardware, particularly a kind of at thin microscler and tool complicated shape, as the technological method for processing of complex-shaped surface mould, groove, hole and volume ratio variation metalwork greatly.
At present for the metalwork that approaches microscler and tool complicated shape, as products such as adjustable wrench, general simple casting or the forging process of all adopting, these two kinds of processes belong to mature technology, the former has certain advantage for the processing of the member with complicated shape, but the moulding qualification rate for thin elongated metal spare processing is low, casting flaws such as the sand holes of product appearance, pore can't remedy, product surface fineness is low, presentation quality is poor, especially literal, pattern quality is poor, the intensity of product, toughness are also lower; Utilize the forging process product processed, the product appearance quality is good, is suitable for the processing of thin elongated metal spare, and to the extremely difficult moulding of the member of complex-shaped surface mould and shape, the position that changes greatly for volume ratio also is difficult to moulding, and difficulty of processing is big, high material consumption, the manufacturing cost height.
The objective of the invention is to utilize existing ripe casting, forging process, designing a kind of technological method for processing with its two combination comes thin microscler and the hardware tool complicated shape are processed, in the hope of utilizing these two kinds of technologies advantage separately, overcome its deficiency separately, simplify the manufacture process of product, reach and guaranteeing significantly to reduce the purpose of its manufacturing cost under the product quality premise.
Main technique methods of the present invention is as follows: a kind of manufacture method of thin and long complex-shaped metal part, it is mainly put: the product of complicated shape make to(for) desire, wait the position greatly as complex-shaped surface mould, groove, hole and volume ratio variation, fruit is used the moulding of precision casting process method, making full use of the advantage of casting technique, and reserve joint; It is docked with the metal stock of desiring to be made into thin microscler position, and its docking calculation can adopt electricity butt joint or friction docking calculation, and the metal stock of this being desired to make again thin microscler position carries out die-forging forming, cuts edge at last, polishes and get final product.
Through practice test, prove the product that is processed into this method, its quality can reach the requirement of regulation fully, and existing process ratio, and its process route is simple, and processing cost is reduced significantly, has high economic benefit.
Be an embodiment who utilizes this process processing and manufacturing adjustable wrench below:
For the head of adjustable wrench, adopt precision casting process finish its macropore, notch, three curved, four eyed is sub and the moulding of outward appearance cambered surface, and reserves joint; Utilize electricity butt joint or friction docking calculation to desire in order to make the corresponding round steel of its shank again to connecting, by the rolling shank blank of rolling mill, again with metal forming machinery with its die-forging forming, or directly utilize roll forging machine that it is carried out the roll forging moulding, cut edge at last, polish and promptly get finished product.Because of technologies such as hot investment casting, die forging, butt joint, side cut, polishing all belong to existing maturation process, so its product quality can guarantee reliably that the while does not also give unnecessary details again to its process detail as space is limited.
Claims (2)
1, a kind of manufacture method of thin and long complex-shaped metal part is characterized in that: the complicated shape for desire making product, change the position of waiting greatly as complex-shaped surface mould, groove, hole and volume ratio, and adopt the hot investment casting moulding, and reserve joint; It is docked with the metal stock of desiring to be made into thin microscler position; The metal stock of again this being desired to make thin microscler position carries out die-forging forming, cuts edge at last, polishes and get final product.
2, manufacture method according to claim 1 is characterized in that: described butt joint can be adopted electricity butt joint or friction docking calculation.
