Abstract
The invention relates to the technical field of mechanical forging, in particular to a hydraulic machine and a technology for using the hydraulic machine for carrying out thick flange punching. The punching technology comprises following steps: (a), flange blanks which are detected to be qualified are placed in order; (b), the placed flanges are moved to a working table of the hydraulic machine; and (c), a suction cup is used for sucking one flange to place the flange on a mold, with a buffer device, of the hydraulic machine, a mounting hole in the flange is punched, the working pressure of the hydraulic machine ranges from 180 T to 220 T, and the buffer force of the buffer device ranges from 8 T to 12 T. The method for using the hydraulic machine for carrying out thick flange punching can ensure that the punching precision is free of deformation, the punching center distance is not changed, and meanwhile it is ensured that a puncher pin is not prone to breaking.
Description
Technical field
The present invention relates to machinery technical field of forging, be specifically related to a kind of hydraulic press, use this hydraulic press to carry out
The technique of thick flange punching.
Background technology
Every union piece making at two planar perimeter to be connected with simultaneously closing, general referred to as " method
Blue ", it can be common that the connection between pipeline and pipeline, the connection etc. between equipment and equipment, flange has pole
Big practicality.Perforation on flange, perforation just can complete to install, and thin-wall flange is by boring, punching press
Can realize.And thick wall flange, especially punching thickness are far longer than punching hole diameter, use drilling machine boring
Efficiency is low, and centre-to-centre spacing often changes, and precision cannot ensure；Using punch press punching, drift often ruptures, effect
Rate is low, wastes huge.So how ensureing that punching precision is the most indeformable, punch center is away from indeclinable situation
Lower high efficiency realizes just being particularly important.
Summary of the invention
It is an object of the invention to provide a kind of hydraulic press, use this hydraulic press to carry out the technique of thick flange punching,
Using hydraulic press to thick flange punching, it is ensured that punching precision is indeformable, punch center is away from not changing, same
Time ensure drift not easy fracture.
For achieving the above object, the technical solution adopted in the present invention is: the technique bag of a kind of thick flange punching
Include following steps:
A the most qualified flange blank is sequentially put by ()；
B () moves to the flange being well placed on the work top of hydraulic press；
C () picks up a flange in the mould being put into the hydraulic press being provided with buffer unit with sucker, rush
Installing hole on flange, the operating pressure of hydraulic press is 180-220T, and the cushion effect of buffer unit is 8-12T.
Preferably, in step (c), the drift downstream rate of hydraulic press is 140-160mm/s.
Preferably, described flange is thick wall flange, and described thick wall flange includes that body, body are provided with mesopore,
Be respectively arranged at the two ends with an installing hole, the length of installing hole and the aperture ratio of installing hole of mesopore are 1.3-1.5:1.
Preferably, described hydraulic press includes workbench and drift, and workbench is provided with is easy to accommodating described flange
Groove, the position of drift is corresponding with the position of installing hole.
After using technique scheme, the present invention has the positive effect that:
The present invention uses hydraulic press to carry out the punching of thick wall flange installing hole, for punching thickness much larger than punching
The situation of diameter, it is ensured that punching precision is indeformable, punch center, away from not changing, ensures drift not simultaneously
Easy fracture, uses traditional drilling machine or punch press efficiency low, and waste is big, the present invention for installing hole length with
The aperture ratio of installing hole is the thick wall flange of 1.3-1.5:1, can go out installing hole accurately, solve use
The defect that drilling machine boring or Presser Dashing pore area come.
Accompanying drawing explanation
Fig. 1 is the structure chart of the flange of the present invention；
Fig. 2 is the structure chart of the hydraulic press of the present invention.
Wherein: 1, body, 2, mesopore, 3, installing hole, 4, workbench, 5, drift.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
In the present invention, unless otherwise clearly defined and limited, term " install ", " being connected ", " connection ",
The term such as " fix " should broadly understood, connect for example, it may be fixing, it is also possible to be to removably connect,
