Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing hot spinning production adopts manual hand-held or fixed on the wheel seat for flame heating, which cannot accurately control the temperature of the workpiece, cannot meet the tolerance requirements, and cannot flexibly control the heating area of ​​the flame. The temperature field of the workpiece is uneven, and the flame crosses the boundary and is easy to burn the equipment. Provide an independent numerical control follow-up flame heating device for the hot spinning machine

Abstract

The invention discloses an independent digital flame following and heating device of a hot spinning machine and relates to a hot spinning workpiece heating device, aiming to solve the problems that a workpiece is manually held or fixed on a spinning seat for flame heating in the traditional hot spinning production, so that the temperature of the workpiece cannot be accurately controlled, the tolerance requirement cannot be met, a heating area of the flame cannot be flexibly controlled, the temperature field of the workpiece is not uniform, and equipment is easy to be damaged by the flame crossing the border. In the invention, a shell on a longitudinal slide mechanism is connected with a permanent seat through a connecting element, and a slide frame on a vertical slide mechanism is connected with a longitudinal screw nut on the longitudinal slide mechanism through a connecting element; a connecting plate is connected with a vertical screw nut through a connecting element; each adjustment mechanism consists of a supporting post and an adjustment frame, and the adjustment frame is fixed on the supporting post; the two adjustment mechanism are longitudinally arranged along the permanent seat, and the supporting posts on the adjustment mechanisms are fixedly arranged on an adjustment flat panel; and each adjustment frame is provided with a heating torch. The invention is used for a device for accurately heating during workpiece hot spinning.

Description

technical field [0001] The invention relates to a heating device for hot spinning workpieces. Background technique [0002] The spinning process is a plastic processing process for hollow rotary parts with a long history. It combines the characteristics of forging, extrusion, deep drawing, bending, ring rolling, cross rolling and rolling. With the help of the feed motion of the rotary wheel, it pressurizes the metal blank rotating with the mandrel, so that it produces continuous local plastic deformation and is formed into a hollow rotary part. Modern spinning technology has been widely used in civil industries such as machinery, chemical industry, electrical appliances, automobiles and light industry, especially in cutting-edge fields such as aviation, aerospace and weapon industry. In the aerospace and military industry sectors, the processing of various rotary parts occupies a large proportion in production. These parts include jet engine support cones, turbine shafts, ...
