Abstract
The utility model discloses a cold heading die capable of heading parts with rod bosses, which comprises a die sleeve, a die core, an upper punch, a push rod, guide keys, a bush, knockout blocks, springs and a die cushion; the bush is mounted in the die sleeve and cooperates with the die sleeve in a sliding manner; the bush is provided with a conical knockout block-mounting hole and a cylindrical die core-mounting hole; the knockout blocks cooperate with the bush in a sliding manner; the die core cooperates with the bush in a sliding manner; the bush and the knockout blocks are respectively provided with guide key slots; and the knockout blocks can freely slide along the guide keys in the conical hole of the bush. During operation, the knockout blocks and the bush float together to head a part; after heading, the push rod pushes the workpiece, the knockout blocks freely slide along the guide keys on the conical surface of the bush, the die hole size of the knockout blocks is enlarged, the workpiece is separated from the knockout blocks, and the push rod pushes out the workpiece; and the springs push the bush, so that the bush is automatically restored. The utility model has the advantages that: knockout positioning is good, the knockout blocks can be forcibly and accurately separated, and operation is reliable; application is flexible, the structure is simple, the manufacturing cost is low, the service life is long, and maintenance and replacement are convenient.
Description
Technical field
The utility model belongs to technical field of mold, relates to a kind of cold heading die, relates in particular to the cold heading die that a kind of fixture of upsetting has bar portion boss spare, is specially adapted to the system of upsetting and produces the part that there is boss in bar portion.
Background technology
How traditional bar portion band boss spare is produced with cutting process.There is the part of boss in known employing sub-module cold upsetting production bar portion, needs hand hammer to knock sub-module and separates with product, and it is time-consuming, unreliable that sub-module and product separate, and more can't cold-heading process on automatic cold header.
Summary of the invention
The utility model discloses a kind of fixture of upsetting has the cold heading die of bar portion boss spare, to solve in the prior art problems such as sub-module and product be not easily separated, time-consuming, unreliable.
The utility model comprises die sleeve, core rod, upper punch, push rod; It is characterized in that: also comprise feather key, lining, sub-module, spring, die-cushion; Lining and die sleeve are slidingly installed in die sleeve; Lining has taper sub-module installing hole and column core rod installing hole; Sub-module and lining are slidingly installed in lining taper sub-module installing hole; Core rod and lining are slidingly installed in lining column core rod installing hole; Core rod has workpiece and ejects the hole; Push rod is installed in the core rod workpiece and ejects in the hole; Die-cushion is installed in after the core rod, and the spring pretension is installed between lining and the die-cushion; Die-cushion is fastened on the die sleeve; Has the guiding keyway on lining, the sub-module respectively; Feather key is installed in the guiding keyway of lining, sub-module; Sub-module can be free to slide in the lining bellmouth along feather key.
The utility model sub-module quantity is 2-4; Feather key is special-shaped feather key; Quantity is 2-4 accordingly; The corresponding abnormity guiding keyway of lining and sub-module with equal number.
The utility model sub-module cooperates cone angle in 16 ° of-22 ° of scopes with lining.
During work, blank before the upper punch upsetting squeeze is upset, sub-module and lining float together, and blank bar portion produces boss before the rammer, and part after the type of making of upsetting is upset is finished the rammer of part and is made type; After type was made in rammer, push rod promoted workpiece, and sub-module is free to slide at the lining conical surface along feather key, and it is big that the sub-module mold hole dimension becomes, and workpiece breaks away from sub-module, and push rod is released workpiece; Spring promotes lining, makes lining automatically reset to the mould upper end.
The utility model advantage is: divide mould to have good positioning, sub-module can be forced and accurately separate, reliable operation; Have application flexibility, can be applied to produce on the multi-locating automatic cold forging machine, also can be applicable to branch preface processing on the forcing press according to the product shape facility.Mould structure is simple, low cost of manufacture, and the life-span is long, is convenient to maintenance and replacing, and is economical and practical.
