Abstract
The invention discloses a cold extrusion forming process of an inner cavity of an outer ball cage. According to the process, firstly, blanks are put in a cold extrusion female mold of a forging press, and a No.1 hydraulic cylinder of the forging press downwards moves so that a cold extrusion punching head enters an inner cavity of the blanks; a No.2 hydraulic cylinder of the forging press downwards moves so that the cold extrusion punching head is open through expansion; a No.3 hydraulic cylinder of the forging press downwards moves, and the cold extrusion punching head and the blanks are pressed into the cold extrusion female mold together so that the blanks are formed; and after the blanks are formed, the No.2 hydraulic cylinder, the No.1 hydraulic cylinder and the No.3 hydraulic cylinder of the forging press sequentially reset, the formed blanks are taken out from the cold extrusion female mold, and the cold extrusion forming operation is completed. The cold extrusion forming process has the advantages that the metallographic structure and the smooth finish of the inner cavity of the product are effectively improved, the abrasion resistance, the intensity and the toughness of the work surface of the products are improved, the processing process is optimized, multiple mechanical processing work procedures are reduced, the manufacture cost is effectively saved, in addition, the operation efficiency is improved, and the manufacture period of the product is obviously shortened.
Description
Technical field
The present invention relates to ectosphere cage inner chamber manufacture field, specifically is a kind of ectosphere cage inner chamber cold extruding formation process.
Background technology
Internal spherical cage and ectosphere generally are called the ball cage, are to be called " constant velocity cardan joint ", are the vitals in the car drivetrain system; Its effect is that the power with engine is delivered to two front vehicle wheels from speed changer, drives car and runs at high speed, and traditional handicraft is: the blank after the forging, thick, finish turning inner chamber, rough mill inner chamber, finish-milling inner chamber; Traditional handicraft needs multiple tracks cold working operation, causes the product manufacturing cycle long, and cost is high; The product precision is difficult to guarantee that scrappage is high.The inner chamber metal streamline is cut off, and inner chamber is easy to wear, influences the service life of product.
Summary of the invention
The purpose of this invention is to provide a kind of ectosphere cage inner chamber cold extruding formation process, improve the quality of products, simplify technological process, practice thrift cost.
Technical scheme of the present invention is following:
A kind of ectosphere cage inner chamber cold extruding formation process may further comprise the steps:
(1), will pass through warm forging just the blank of one-step forming put into the Cold Extruding Die of forging press; Forging press has a hydraulic cylinder, No. two hydraulic cylinders, No. three hydraulic cylinders, No. four hydraulic cylinders; At first forging press hydraulic cylinder is descending; It is descending that drive is in the cold extrusion drift of contraction state, makes cold extrusion drift get into the inner chamber of blank;
(2), No. two hydraulic cylinders of forging press are descending, it is descending to drive the inner awl bar of cold extrusion drift, makes the awl bar be pressed in the taper hole of cold extrusion drift head, the awl bar stretches into downwards and makes extruding drift spreading gradually in the taper hole;
(3), No. three hydraulic cylinders of forging press are descending, drive cold extrusion drift and blank and are pressed into together in the Cold Extruding Die, and cold extrusion drift and cold extrusion groove are cooperatively interacted the blank moulding;
(4), after the blank moulding, No. two hydraulic cylinder backhauls of forging press make cold extrusion drift shrink; Cold extrusion drift and cold extrusion groove are separated; A then hydraulic cylinder backhaul of forging press makes that the blank after cold extrusion drift and the moulding breaks away from forging press No. three hydraulic cylinder backhauls then; Take out the blank after the moulding in the Cold Extruding Die, accomplish cold extrusion shaped operation.
Described forging press adopts the cold extrusion forcing press.
Beneficial effect of the present invention:
(1), the present invention's fineness and metallographic structure of effectively having improved product cavity, improved the wearability of product working face.
(2), need not to carry out again cold working after adopting cold-extrusion technology of the present invention, make the product cavity metal streamline intact, effectively improved the intensity and the toughness of product.
(3), the present invention optimized processing technology, reduced multiple tracks machining operation, effectively practiced thrift manufacturing cost.
(4), the present invention promoted operating efficiency, obviously shortened the manufacturing cycle of product.

Fig. 1 process chart of the present invention.
The specific embodiment
Referring to Fig. 1, a kind of ectosphere cage inner chamber cold extruding formation process may further comprise the steps:
(1), will pass through warm forging just the blank of one-step forming put into the Cold Extruding Die of forging press; Forging press adopts the cold extrusion forcing press; Forging press has a hydraulic cylinder, No. two hydraulic cylinders, No. three hydraulic cylinders, No. four hydraulic cylinders; At first forging press hydraulic cylinder is descending, and it is descending to drive the cold extrusion drift that is in contraction state, makes cold extrusion drift get into the inner chamber of blank;
(2), No. two hydraulic cylinders of forging press are descending, it is descending to drive the inner awl bar of cold extrusion drift, makes the awl bar be pressed in the taper hole of cold extrusion drift head, the awl bar stretches into downwards and makes extruding drift spreading gradually in the taper hole;
(3), No. three hydraulic cylinders of forging press are descending, drive cold extrusion drift and blank and are pressed into together in the Cold Extruding Die, and cold extrusion drift and cold extrusion groove are cooperatively interacted the blank moulding;
(4), after the blank moulding, No. two hydraulic cylinder backhauls of forging press make cold extrusion drift shrink; Cold extrusion drift and cold extrusion groove are separated; A then hydraulic cylinder backhaul of forging press makes that the blank after cold extrusion drift and the moulding breaks away from forging press No. three hydraulic cylinder backhauls then; Take out the blank after the moulding in the Cold Extruding Die, accomplish cold extrusion shaped operation.
