Greatly, these can all reduce the mechanical property of valve body.The defect for appearing in brake valve body surface can be removed by way of machining,
But the coarse as-cast structure still moment affects the service performance of casting.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of brake valve body and its forging technologies, raw by way of forging
Brake valve body is produced, forging dense structure, crystal grain is tiny, metal streamline is reasonably distributed and complete continuous, considerably increases brake valve body machine
Tool performance.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of brake valve body, including forging are provided
Main body, Zuo Falan, right flange, upper flange, the first valve core channel, the second valve core channel, the forging main body are symmetrical
It is inverted T shape, the left end of the forging main body is provided with left flange, and the right end of the forging main body is provided with right flange, described
The upper end of forging main body is provided with upper flange, and the left flange and right flange center, which are horizontally disposed with, circle that is coaxial and being mutually communicated
The first valve core channel of cylindricality, the second spool of cylinder that the upper flange center vertical is provided with the first valve core channel of access are logical
Road, the diameter of second valve core channel are greater than the diameter of first valve core channel.
A kind of forging technology of brake valve body, comprising the following steps:
Step 1: the bar descale that will be heated；
Step 2: base；
Step 3: blank is placed in die cavity, upper/lower die closure carries out finish-forging in finish-forging die cavity；
Step 4: under the cooperation of mold, on the one hand the forward extrusion billet of upper punch, Zuo Chongtou, right formed punch makes upper flange, a left side
Flange, right flange forming, on the other hand form bore of the punch slowly, stop after formed punch advances to designated position, form first
Valve core channel, the second valve core channel.
Step 5: the blank material forged is taken out, is machined, shot-peening.
The beneficial effects of the present invention are: a kind of brake valve body provided by the invention and its forging technology, by way of forging
Brake valve body is produced, forging dense structure, crystal grain is tiny, metal streamline is reasonably distributed and complete continuous, considerably increases brake valve body
Mechanical performance.
