Introduction
Interpretation of the requirements for the preparation of the material consumption process quota of stamping parts
1. Overview of the standard
GB/T 34360-2017 "Requirements for the preparation of material consumption process quotas for stamping parts" is an important standard in my country's stamping manufacturing field. It mainly stipulates the principles and methods for the preparation of material consumption process quotas for ordinary stamping parts in batch production of plates and coils.
This standard is proposed and managed by the National Technical Committee for Forging Standardization (SAC/TC74) and is applicable to stamping parts manufacturing enterprises in batch production.
2. Background of standard formulation
With the rapid development of my country's manufacturing industry, stamping technology is increasingly used in the automotive, home appliances, aerospace and other industries. However, in the stamping production process, the preparation of material consumption quotas has always been the focus and difficulty of enterprise cost control and process optimization.
The formulation of GB/T 34360-2017 standard aims to unify the compilation method of stamping parts material consumption process quota, improve the production efficiency and resource utilization of enterprises, and provide technical specifications and reference basis for the industry.
| Standard dimensions | GB/T 34360—2017 | Comparison standards |
|---|---|---|
| Scope of application | Ordinary stamping parts in batch production of plates and coils | Other stamping related standards (such as GB/T 8541 forging terminology) |
| Quota composition | Blanking loss, stamping loss, net weight of parts | Specific calculation method is not clear |
| Calculation method | Material selection method and coefficient method | Only provide qualitative guidance |
3. Interpretation of the core content of the standard
3.1 Quota composition
The process quota of material consumption of stamping parts mainly includes three parts:
- Cutting loss: the residual material generated in the process of cutting the plate into strips, including the head and tail of the coil.
- Pressing loss: process loss (overlap, trimming allowance) and design loss (structural waste).
- Part net weight: the mass of the finished part, excluding the coating mass.
3.2 Calculation method
The standard provides two main calculation methods:
- Material selection method: calculate the material consumption quota of a single piece according to the reasonable arrangement of the blank size. Applicable to batch production.
- Coefficient method: Calculate quotas based on cutting material utilization or surplus material rate, which is more flexible.
4. Implementation suggestions
In order to ensure the effective implementation of the standard, it is recommended that enterprises take the following measures:
- Establish standardized processes: From raw material procurement to quota calculation, clarify the operating specifications of each link.
- Strengthen technical training: Provide systematic training for technical personnel to ensure that they are proficient in the calculation methods and table usage in the standard.
- Optimize layout design: Use advanced layout software to improve material utilization and reduce waste.
- Regular evaluation and optimization: Continuously optimize the quota preparation plan based on production data and feedback.
