Problems solved by technology

[0003] However, the following problems exist in the grinding of existing stainless steel flanges. a. When grinding traditional flanges, it is generally necessary to manually grind with sandpaper. When grinding by machine, it often causes uneven grinding and slow grinding speed, which reduces the grinding quality of stain

Embodiment Construction

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0037] Such as Figure 1 to Figure 9As shown, a batch processing method for stainless steel flanges mainly includes the following steps:

[0038] Step 1, prefabrication operation, the stainless steel flange raw material is manufactured into a predetermined size, and the stainless steel flange blank plate is obtained;

[0039] Step 2, forging operation, performing forging operation on the stainless steel flange blank plate obtained in step 1, to obtain the forged flange blank plate;

[0040] Step 3, cold and heat treatment, heat-treating the forged flange blank plate obtained in step 2, and then cooling naturally to obtain a cooled flange blank plate;

[0041] Step 4, cutting operation, performing cutting operation on the cooled flange blank plate ...

Abstract

The invention relates to a batch treatment method for stainless steel flanges. The batch treatment method for the stainless steel flanges mainly comprises the following process steps of prefabricationoperation, forging operation, cooling and heat treatment, cutting operation, drilling operation, grinding operation, inspection operation and the like. Stainless steel flange grinding equipment usedin the method comprises a bottom plate, a clamping device and a grinding device. The method can solve the following problems, existing when stainless steel flanges are ground by adopting an existing method, that a, when flange plates are ground by adopting the traditional method, abrasive paper generally needs to be manually held by hand for grinding, so that such grinding wastes time and labor, or when a small electric grinding machine is adopted for grinding, uneven grinding is frequently caused, the low grinding speed is low, the grinding quality of the stainless steel flanges is reduced, and subsequent use of the stainless steel flanges is influenced; and b, when an existing stainless steel flange grinding device is used for grinding different stainless steel flanges, different grinding heads need to be replaced, so that time is wasted, and the efficiency is low. The batch treatment method can improve the stainless steel flange grinding efficiency and quality.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a batch processing method for stainless steel flanges. Background technique [0002] Flange is a kind of disc-shaped part, which is the most common in pipeline engineering. Flanges are used in pairs and matched with flanges on valves. Flanges are mainly used for the connection of pipelines. In the pipelines that need to be connected, each installation A piece of flange, and then add flange pads between the two flanges, and finally tighten the two flanges with bolts to make them tightly combined to become a detachable joint, which can realize static pipe to For the connection between rotating or reciprocating equipment, stainless steel flanges need to be polished during the manufacturing process. [0003] However, the following problems exist in the grinding of existing stainless steel flanges. a. When grinding traditional flanges, it is generally necessary to ma...
