Abstract
The invention relates to a Bailey part truss pin forging process capable of saving steel materials and production cost and used for a steel structural bridge and particularly provides a novel process and a related die. A step surface and a directional groove of a workpiece are formed by pressing in one step. The novel process comprises the following steps of: firstly, manufacturing a high-strength close type die by using alloy hot die steel, and installing the die on a die forging machine; heating a blank to about 1200 DEG C, placing the blank into the die for pressing forming in one step so that the related dimension of the blank meets the requirements of design; finishing in place by using a lathe and drilling after cooling; and feeding for heat treatment, quenching and galvanization so as to manufacture a finished product. The invention changes the cutting machining of the traditional process into forging and pressing forming, saves the steel materials of 0.9 kg per product and the machining time of 20 minutes, reduces the material cost by 25 percent, and greatly enhances the production efficiency.
Description
Technical field
The present invention is a bridge steel structure with a kind of product Forging Technology (annotate: this product is a shellfish thunder sheet truss pin) that can strengthen steel bridge bonding strength and rigidity on the shellfish thunder chip part.
Background technology
The traditional production method of this product is: smooth bar is formed through lathe car system, and steel consumption is excessive, has increased production cost.
Summary of the invention
For the consumption that saves material, reduce its production cost, the invention provides a kind of novel process and mould the disposable compacting of workpiece is formed.Its concrete technical scheme is as follows:
At first make a cover high strength closed molds and be installed on the die forging machine with alloy mold heat steel, then used round steel is heated to 1200 ℃, the compression moulding of die forging machine of packing into, make forging reach designing requirement (needing steel rough turn and required consumption all to save tradition), be finished product behind the finish turning.The present invention saves steel 25% than every of traditional processing mode.
Description of drawings
Fig. 1 be shellfish thunder sheet truss pin shaping mould (1, for truss pin moulding upper mould, 2, be truss pin shaping mould counterdie).
Fig. 2 is shellfish thunder sheet truss pin (3, for truss pin part).
Claims (2)
1. a new steel structure bridge shellfish thunder sheet is with truss pin Forging Technology:
Its technical process is: after the truss pin material of required forging was heated to 1200 ℃, the shaping mould compression moulding on die forging machine of packing into put in place through the lathe finish turning again, boring, and heat treatment is finished product after zinc-plated.
2. mould one cover that supporting this technology is made.
