Composition of the Glass Curtain Wall Processing Technology Flow
It includes the following: the processing flow of special accessories and iron angle brackets, aluminum profile processing flow, frame assembly flow of supporting components, assembly flow of operable sashes, and assembly flow of unit components.
Main Specialized Machinery and Equipment to Be Invested in the Glass Curtain Wall for This Project
Refer to the Machinery and Equipment Allocation Plan section for details.
Production Deployment
The production plan is a four-level plan that is attached to the overall project's construction plan, design plan, and procurement plan. It is a crucial link in ensuring that the project is completed on schedule. On-time material delivery is a prerequisite for normal production. Since the production plan is a four-level plan, it is developed by working backward from the construction schedule. Therefore, controlling the key points of each stage is crucial to ensuring the project timeline.
To this end, we require the design department to complete designs as quickly as possible and prepare material requisition and processing orders in advance. Meanwhile, the purchasing department must arrange production as soon as possible according to the material requisitions from the design department and the purchasing plan, ensuring that the construction site's installation needs are met.
After the materials arrive at the factory, the company will process and produce them in sequence from the inside out according to the construction order of the curtain wall, namely: processing of embedded parts, processing of transition parts, steel processing, aluminum material fabrication, unit part fabrication, and unit part installation.
Based on the processing volume of this project, we will operate two production lines continuously, with two or three shifts to maintain production efficiency.
Processing Flow of Special Accessories and Iron Angle Brackets
Key points for processing special accessories and iron angle brackets:
(1) Order Acceptance
1.After receiving the processing order, the person accepting the order must thoroughly verify whether the relevant data and simplified diagrams indicated in the processing order match.
2.If everything is compliant, material planning and material requisition procedures shall be carried out.
(2) Material Requisition
1.A material requisition form must first be obtained from the production department, and then verified by the materials department.
2.Material requisition must be approved by the warehouse keeper before issuance.
(3) Cutting
1.A 2500mm × 13mm shearing machine is used for cutting.
2.Before shearing, the equipment must be lubricated and tested under no-load conditions to ensure normal operation. Preparation for cutting should be made under standard conditions.
3.When feeding the plate into the shearing kerf, the operator must use a unified command or hand gesture to indicate that cutting can proceed before depressing the clutch.
4.The allowable error between the plate size and the size specified in the processing order is 0.5mm–1mm, including diagonal dimensions.
5.After cutting, the plate must be neatly placed at the lower hole processing station.
(4) Hole Processing
1.Hole processing equipment generally uses drilling machines and milling machines.
2.Machine operators must be proficient in the machine's performance and operating procedures.
3.Operators must maintain high concentration during operation. Safety precautions must be taken when feeding and withdrawing workpieces, using jigs and fixtures instead of manual handling.
4.Workpieces must be processed according to the processing order requirements. After completion, they should be neatly stacked for bending.
(5) Bending
1.Operators must understand the performance and operating procedures of the bending machine.
2.Before bending, a detailed analysis of the processing order requirements must be conducted to determine whether the machine can meet the bending specifications.
3.Bending equipment includes punch presses and hydraulic bending machines. Generally, bending machines are used for iron and stainless steel plates with a thickness of 1mm–4mm, while punch presses are used for 5mm–8mm plates.
4.The bent workpieces must meet the requirements of the processing order.
5.The bending angle can be referenced from the machine's bending parameters.
(6) Welding
- Operators must wear appropriate protective gear before welding.
- Welding of iron plate parts must be carried out according to the processing order requirements, and all relevant data must be verified for consistency.
- During welding, operators must follow all welding standards and avoid producing defects such as porosity, undercuts, or uneven weld seams.
- After welding, slag must be removed. Any defective products found must be reworked.
- Stainless steel welding uses an argon arc welding machine and stainless steel welding rods.
(7) Electroplating
After the iron parts are finalized, those requiring galvanization according to technical requirements are sent to external suppliers.
(8) Storage
- Upon entering the warehouse, the workpieces must be carefully inspected for compliance.
- The storage location should be dry and free from corrosive substances.
