It relates to the production of parts. In particular, the present invention
Design and production information to facilitate the production of sheet metal parts
Equipment and methods for managing and distributing throughout the factory
Things. Background information Traditionally, for example, songs in advanced production facilities for sheet metal
The production of sheet metal involves a continuous production manufacturing stage. No.
The first stage is the design stage, based on customer specifications
A sheet metal part is designed. Usually customers have specific sheets
Order production in equipment of metal parts. Customer order
Examples, product and design information needed to manufacture parts in the factory
Contains. This information can be, for example, the geometric dimensions of the part.
Method, materials required for parts (eg steel, stainless steel)
Steel or aluminum), special molding information, quantities,
May include delivery date. Requested by the customer
Sheet metal parts are designed and manufactured for a wide variety of applications
I can do it. For example, manufactured parts will eventually
Computer cases, switchboards, aircraft armrests,
May be used for car door panels. design
In the stage, the design of sheet metal parts is
Assisted design (CAD) system for manufacturing equipment design department
Made in. Depending on the customer's specifications, the programmer can
Two-dimensional (2-D) modeling of sheet metal parts using the D system
You can also create Dell. Customer is usually important for parts
Provide blueprints with various geometric dimensions. This blueprint
Is a special molding or symbol included in the part or sheet metal
It may also indicate holes or other openings on the surface of the part. Design professional
Glamor creates a 2-D model with a CAD system
I often use this blueprint. This 2-D model is
Also includes bending line and / or dimensional information for sheet metal parts
It may include a top view and one or more perspective views.
You. Before actually starting bending of sheet metal parts,
Stamping and / or cutting parts from raw materials
There must be. Punching when processing stock materials
Control press or plasma or laser cutting machine
Computer numerical control (CNC) or number
Value control (NC) is used. Process this inventory material
For ease of use, the design programmer is
Manufacturing (CAM) system or CAD / CAM system
To create a control code based on the 2-D model
Rukoto can. This control code includes a stamping press
And / or sheeting from stock material for use in cutting machines
Component professional for punching or cutting metal parts
Grams may be included. Next to the manufacturing process
Step is the bending planning stage. At this stage, bending
A work plan is made by the bending operator at the workshop.
You. Operators usually have one cut or stamped
Or a blueprint or
A 2-D drawing is passed. Bending operation with these materials
The data defines the tool to be used and the bending procedure to be performed.
Make a machining plan. Operators are in the bending shop
Data based on the bending code entered or the bending plan
Like a CNC press brake that can create customized programs
Also includes a CNC metal bending machine. Bending plan created
The operator performs an initial test of the bending sequence.
A work place for In this test phase,
Or the cut material is manually incorporated into the press brake
Press brakes are manufactured according to the programmed sequence.
Operated to bend the work. The operator
Analyze the finished bent sheet metal parts to meet customer specifications
Check for conformance. This press brake
Depending on the results of the initial work on the
They may edit the system and modify the bending order. Operating
Also ensure that the design of sheet metal parts can be modified appropriately.
In some cases, the results are fed back to the design department. Te
The strike is a design specification that normally requires bent sheet metal parts
It continues until it falls within. End of the production process
One of the stages is the bending stage. A bend plan is created,
After being tested, the bending operator can
Equipped with a tool, the bending plan and the stored bending program
Activate the press brake according to the system or code. Song
The required amount of stamped or cut material
Delivery as specified and other work is ensured
A work schedule has been created as if it had been completed by
You. The work schedule is in the early stages of the production process and / or the whole process
Created or modified by the workshop supervisor in parallel
There is also. When the production of the last bent sheet metal part is completed,
Parts are collected and packed for delivery to the customer.
You. Normal manufacturing and manufacturing processes have some drawbacks and disadvantages.
is there. For example, each customer's design and manufacturing data is usually
(For example, in a file cabinet with paper)
Stored electronically (eg on disk or magnetic tape)
However, such data is usually stored separately.
Not easy to search. In addition, in many factory environments
Distribution of important work information is distributed throughout the factory
In the form of work or planning papers As a result, the data
Often lost or damaged, to previous or similar work
It becomes difficult to search for design / manufacturing data. Join
However, due to the lack of data storage methods,
Valuable to all factories' workshops and other locations.
Time is lost. Also, the design of parts and the creation of bending plans
Mainly performed by design programmers and bending operators
It depends largely on personal knowledge, skills and experience
Production time between sheet metal parts and bending planning
Lost. In recent years, customary sheet metal manufacturing processes have been improved
Development and attempts to improve efficiency throughout the process
Has been done. For example, a commercially available CAD / CAM system
Two-dimensional (2-D) and three-dimensional (3-D) in systems
Manufacturing and manufacturing of bent sheet metal through the use and development of modeling.
The process and modeling was facilitated and improved. Now the design plan
Logramers and operators use 2-D and 3-D displays
Better understand the shape of the part, and
Code order can be created more efficiently.
You. The ability to electronically store and transfer data
Improved the flow of information from the design department to the workshop. Con
With the advancement of computer and data communication networks,
Place old paper tapes or magnetic disks in cabinets or
It is no longer necessary to find out from the file. Such progress
Despite the existing design across the organization and factory environment
And there is still a need to improve the organization and flow of manufacturing information.
For example, in a conventional manufacturing system, each customer's
Key design and manufacturing information can be easily accessed anywhere in the factory.
Accessible and searchable.
Not. Previous systems also featured sheet metal parts.
Job information based on various characteristics, such as signs and characteristics
No search function. For example, the same or similar parts
You can search for previous work information based on the search for
Being able to search greatly enhances the overall production process
And reduce the required manufacturing time for future work. Past attempts
Can also be provided by design programmers and shop floor operators.
Lack of ease of designing sheet metal parts. 2-
With D and 3-D modeling systems, designers can
You can better understand the shape and geometry of the product
However, this system allows design programmers and
The burden imposed on pererators has not been reduced. for example
These systems allow design programmers to survive
Easily convert 2-DCAD models to 3-D display
I can not do such a thing. Also, bend plans for the workshop operators
2-D and / or 3-D drawings of parts to help you build
If provided, the operator can manually access the necessary tools and bending procedures.
And / or by trial. SUMMARY OF THE INVENTION In light of the above, the present invention relates to one or more of the inventions
