Problems solved by technology

In addition, preheating can also reduce welding stress and help prevent cold cracks. The traditional method is direct preheating, which tends to cause uneven preheating of the workpiece, so uniform preheating is very important.

Abstract

The invention relates to a device for intermittent preheating and waste heat collection before surfacing. The device comprises a preheating box and a bracket arranged on the preheating box. A treatment device used for providing heat for the interior of the preheating box and collecting waste heat is arranged in the preheating box. An intermittent device used for conducting intermittent preheatingon workpieces is arranged on the bracket, an incomplete gear is driven to be matched with a sliding rod to enable the workpieces to be heated intermittently and evenly, and the phenomenon that the machining effect is affected by subsequent machining due to local overheating is reduced; and meanwhile, by cooperating with an adjusting motor and a steel wire rope to enable a transverse plate to riseand fall, so that placement and taking away of the workpieces are be facilitated.

Description

technical field [0001] The invention relates to the technical field of surfacing welding, in particular to an intermittent preheating and waste heat collection device before surfacing welding. Background technique [0002] Preheating is an effective measure to reduce the cooling rate after welding. It can not only prolong the cooling time within the austenite transformation temperature range, reduce the hardening tendency, but also prolong the cooling time of the welding maximum heating temperature to 100 ° C, which is beneficial to the hydrogen escape. In addition, preheating can also reduce welding stress and help prevent cold cracks. The traditional method is direct preheating, which tends to cause uneven preheating of the workpiece, so uniform preheating is very important. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a device for intermittent preheating and waste heat collection before surfacing. [0004] An ...
