example

[0053] Example: The following is a simple example to illustrate, without loss of generality, assuming that there is only one model in the welding plan.

[0054] 1. If Figure 3.1 As shown, the daily welding planning quantity of the welding workshop is the number above the box, which is 115, 150, 90, 100, 120...etc. If the rolling time window is selected as 3 days, the rolling demand plan of the stamping shop can be obtained as Figure 3.1 , and their numbers are 355, 340, 310, 395... in turn.

[0055] 2. Calculate the batch and batch processing time of all stamping workpieces, such as Figure 4 As shown, the number on the box is the batch quantity, and the number in the box is the batch processing time.

[0056] 3. According to the bill of materials BOM, decompose the stamping demand plan to obtain the demand quantity of each stamping part, and compare it with the actual stock and safety stock of stamping parts, such as Figure 5.1 As shown, the number on the dotted line r...

Abstract

The invention discloses an integrated control system of welding of car body and punching workshop operation; a welding material controller is connected with a welding upper and lower line recognizer so that the upper and lower line car body information of the welding production line is received; subsequently, the material decomposition is carried out according to the process material list corresponding to the car body; the material information required by welding production is generated; relevant information is sent to a material delivery electronic kanban; the welding material controller also sends the welding workpiece require plan to a punching operation scheduler; the data of the punching storage database is updated; the punching operation scheduler obtains the welding workpiece require plan from the welding material controller, obtains the punching part storage quantity from the punching storage database, carries out the scheduling control to the punching operation according to the welding rolling production plan, the welding workpiece require plan and the punching part storage, and updates the data of the punching storage database. The integrated control system of welding of car body and punching workshop operation realizes the running of the car body punching and welding production at high efficiency and low cost, reduces the storage and ensures smooth production with meeting the welding requirements.

Description

technical field [0001] The invention belongs to the technical field of computer integrated manufacturing, and realizes integrated scheduling control of body welding and stamping workshop operations by a computer. technical background [0002] Automobile manufacturing generally includes four major processes: body stamping, body welding, body painting and vehicle assembly. Stamping is the first major process of vehicle manufacturing, and its production adopts the organizational mode of batch operations. According to the welding demand plan and inventory size, the plates are divided into batches, and the production is organized and arranged by changing the stamping dies, fixtures and operating processes. However, during the execution of the stamping production plan, due to the variety of stamping parts, the complexity of the process and the influence of workshop production factors (equipment failure, sheet material shortage, personnel changes), there are often high inventory a...
