Abstract
The invention discloses a method for manufacturing fasteners. The method for manufacturing the fasteners includes steps of firstly, additionally arranging a heating device between a feed wheel of a cold header and a feed inlet of a machine, and primarily heating a connected blank at the heating temperature ranging from 400 DEG C to 700 DEG C until the connected blank reaches a phase-change brittle zone; secondly, cutting the heated connected blank with the temperature ranging from 400 DEG C to 700 DEG C into single blanks; thirdly, secondarily heating portions, which are required to deform, of the cut single blanks at the heating temperature ranging from 780 DEG C to 1000 DEG C; and fourthly, performing die-forging and forming for the heated single blanks with the temperature ranging from 780 DEG C to 1000 DEG C. The method has the advantages that merits of a hot forging process and merits of a cold heading process are combined, the precision and the production efficiency of products are improved, the deformation performance and the strength of the products are enhanced, and the cost is lowered on the premise of keeping the technical superiority.
Description
Technical field
The present invention relates to a kind of production method, particularly relate to a kind of forging method of securing member.
Background technology
At present, conventional securing member production technology mainly contains forge hot, cold-heading, turning three kinds of techniques, and thermal forging technology efficiency is low, precision is low, cost is high, is only applicable to not too tight low-end product; Cold heading technique precision is higher, and just blank production modification amount is less, and product strength is lower; Turning process is only suitable for the securing member of labyrinth, and cost is high, is not suitable for batch production.
Summary of the invention
In order to make up the deficiencies in the prior art, solving the shortcoming of independent forge hot and cold-heading, forge hot workpiece post bake being processed, a kind of securing member production method is provided.
The technical scheme that the present invention solves its technical problem can be:
A kind of securing member production method, a kind of securing member production method described in it, step 1, to take turns to cold headers charging between machine charging aperture and installs a heater additional, carries out first time heat connecting part blank, be heated to phase transformation brittleness district, heating-up temperature is 400 ~ 700 DEG C; Step 2, company's part blank that heating reaches 400 ~ 700 DEG C is cut into single-piece blank; Step 3, will cut single-piece blank and carry out second time heating, only heating needs the position of modification, and heating-up temperature is 780 ~ 1000 DEG C; Step 4, the single-piece blank being heated to be 780 ~ 1000 DEG C is carried out die-forging forming.
The invention has the beneficial effects as follows:
1, the present invention has taken into account the advantage of forge hot and cold-heading two kinds of techniques, has both improve precision and the production efficiency of product, turn improves modification amount and the product strength of product, under the prerequisite keeping technical advantage, reduces cost.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Detailed description of the invention
A kind of securing member production method, a kind of securing member production method described in it, step 1, to take turns to cold headers charging between machine charging aperture and installs a heater additional, carries out first time heat connecting part blank, be heated to phase transformation brittleness district, heating-up temperature is 400 ~ 700 DEG C; Step 2, company's part blank that heating reaches 400 ~ 700 DEG C is cut into single-piece blank; Step 3, will cut single-piece blank and carry out second time heating, only heating needs the position of modification, and heating-up temperature is 780 ~ 1000 DEG C; Step 4, the single-piece blank being heated to be 780 ~ 1000 DEG C is carried out die-forging forming.
