Modularization and standardization management method for trial-manufacturing processing technique of air cylinder cover

Abstract

The invention provides a modularization and standardization management method for the processing technique of trial-manufacturing an air cylinder cover. The modularization and standardization management method includes the following steps that a, modularization classification is conducted and the processing technique of a cylinder cover is divided into five modules; b, a preprocessing module, a rough processing module, an intermediate processing module, a finish processing module and a foundation process in a final processing module are basic processes; c, a standardized working-step module of the foundation process is formulated; d, a non-standard working-step submodule is formulated; and e, existing modules or modules special for design is combined into a novel product. The modularization and standardization management method for the processing technique of trial-manufacturing the air cylinder cover can reduce the work of production organization and technological preparation of a workshop during a product modeling through the modularization and standardization of the processing technique for trial-manufacturing the air cylinder cover, the demand of the product remodeling is met only by conducting the recombination of the modules; and through the modularization and standardization of the processing technique for trial-manufacturing the air cylinder cover can shorten the design circle of the product, can greatly reduce the trial-manufacture cost, so that the contradiction among the variety, the standard, the designing and manufacturing cycle and the cost of the product is solved.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to the technical field of trial production and processing of cylinder heads of diesel engines. Background technique [0002] There are four types of cylinder heads in the diesel engine cylinder head trial production workshop: Tier3 series cylinder heads, DK series cylinder heads, 4DD series cylinder heads, and DH series cylinder heads, 1003011-A14R / B, 1003011-A13R / B, 1003011-A51R / A 、1003011-A52R / A、SF04905517、SF04905518、1002011-90D、1002011-B90D、1002011-91D、1003010-52E、1003010-A52E、1003011-A52E、1003011-B52E、1003011-52E、1002014-53E、1003011-53E , 16 kinds of cylinder heads. Due to the different technical status and processing methods of different platforms and different types of cylinder heads, the tooling and cutting tools are complicated and numerous, which adds considerable difficulty to the production organization and process preparation of the workshop. At the same time, d...

Due to the different technical status and different processing methods of different platforms and different types of cylinder heads, the tooling and tools are complicated and large in number, which adds considerable difficulty to the production organization and process preparation of the workshop

At the same time, due to the small amount of processing in the trial production workshop and the nature of fast model change, the workload required for each model change process is a very labor-intensive and time-consuming task. With the progress of the times, diesel engines are constantly being upgraded. The number of products will also continue to increase. Every time a new cylinder head product trial production is added, it needs to start from process to tooling, from preparation to processing. The cost of trial production will only increase with product upgrades. It has become inventory, and the long inventory backlog is also a waste for the company
