Abstract
The invention discloses a processing method of a core tail of a hydraulic connection hose joint. In a forming technology, a three-wheel rolling machine or a two-wheel rolling machine is matched with a support to realize rolling forming. The processing method comprises the following steps: pre-processing a rolling wheel to the appearance size of the core tail by selecting a proper round steel or steel pipe, putting the rolling wheel into the round steel or steel pipe, and performing squeezing forming of three rolling wheels to obtain the required appearance and size of the core tail. The processing method has the benefits that the three-wheel rolling machine or the two-wheel rolling machine is matched with the support to realize one-time forming, so that the time is short, and the processing is facilitated; about 3,000 core tails can be processed one day; therefore, the production efficiency is greatly improved, and the production cost is greatly reduced.
Description
Technical field
The invention belongs to the technical field of fluid delivery of hydraulic system, specifically relate to a kind of processing method of core tail of hydraulic connecting hose coupling.
Background technology
The core tail design of the existing hydraulic connecting hose coupling be applied in hydraulic pressure or other field is made up of multiple tracks groove and step, the core tail of usual hydraulic connecting hose coupling is formed by turnery processing, long processing time, inefficiency, one chassis bed one day is processing about 300 at most, and need much knives tool, need the equipment such as lathe, numerical control programming and operation, production cost is high, the general rolled thread of traditional screw-rolling machine in addition, not used for the profile that roll extrusion is non-threaded.
Such as: Chinese patent CN200810061360.7 discloses a kind of manufacture method of hose elbow connection, comprise the steps: that a. gets the raw materials ready: prepare a cylindric pipe, and pipe is carried out annealing in process; B. bulge loop is processed: process several bulge loops in one end of pipe by the mode of extruding; C. reducing joint is shaping: the reducing joint processing truncated cone-shaped in the end that pipe has bulge loop one end; D. body bends: bent at the middle part of pipe; E. bump joint is shaping: process bump joint in the end of the other end of pipe, get product.This invention solves the processing of existing flexible pipe when die casting because liquid Metal Filling die cavity speed is high, and fluidised form is unstable, and foundry goods easily produces pore, and the problem such as can not to heat-treat, foundry goods is withheld rear easy to crack.The advantages such as this this flexible pipe of technique manufacture method processing technology is simple, production cost is low, product pipe walls is thinner, good forming effect.
But, this invention remains and uses the machining process such as turning, extruding to prepare hose coupling, for the core tail of the hydraulic connecting hose coupling be made up of multiple tracks groove and step, it still also exists long processing time, complex process, inefficiency, processing cost high-technology problem.
