Specifically, CNC press brake bending machine is a kind of mechanical equipment that bends plates through automated systems and molds, which greatly improves work efficiency and saves time, and indirectly promotes the continuous development of society. What are the inspection methods and usage methods of CNC press brake bending machine programs? The following is an introduction to “the use of CNC press brake bending machine and related content introduction”.
A brief introduction to the inspection program of CNC press brake bending machine in production
1. Confirmation of drawings
Confirm whether customer drawings and department drawings are consistent;
- understand the quality requirements;
- Master the size/item of key control (such as wire drawing and its direction);
2. Material confirmation
- Material distinction (stainless steel, cold-rolled sheet, galvanized sheet,) SUS304 – without magnetism; SUS430 with magnetism, test with a magnet;
- Confirmation of incoming materials;
According to the process card, confirm whether the product has any missing processes, such as “counting punching – deburring – bending” to confirm whether the burrs and sharp corners are removed; “punching – rolling – bending” to confirm whether there is rolling and Whether the circle direction is correct;
Prevent defective products from flowing into this process – that is, “do not accept defective products”;
3. Confirmation of plate thickness – caliper
Avoid burrs to measure the thickness of the board; tear off the protective film to measure the thickness of the board Four appearance confirmation – visual;
- Creases – not too deep, not obvious visually, no feel;
- Strain, scratches – not allowed, not obvious visually, no feel;
- Crushing, indentation – not obvious visually;
- Knife mark – no hand feeling;
- Deformation, bending, pulling material near the bending hole; convex deformation (collision);
- cracks, cracks;
- bumps, scratches;
4. Structure confirmation
To prevent the reverse bending direction of the drawing, when folding into a product, all marked dimensions should be measured, and the next product size should be changed according to the measured actual size to ensure that the product size meets the requirements of the drawing
- Figure out the perspective direction of the drawing, whether the drawing adopts the perspective or the third perspective
- Determine the main view – confirm whether the object is consistent with the drawing
Method: Find different “shapes” on the same surface to distinguish their placement direction
Hole (more – less); side foot (long – short); hole distance (large – small); R angle / hole gap / dead edge (yes – no)
5. Measure the size
The key dimensions marked on the drawing must be measured (if not marked, it will be reported immediately). The distance from the center of the hole to the bending edge is measured by sampling;
6. CNC press brake bending machine mold confirmation – prevent bending
Confirm whether the two rear gauges at the back of the bending machine are locked firmly to prevent the bending caused by loosening;
7. Confirmation of product protection and placement – to prevent defects caused by improper protection/protection and placement
Incoming material confirmation – confirm whether the incoming material is abnormal, whether there is QC signature and seal on the identification card;
- Appearance confirmation;
- Confirmation of operation methods – confirm whether there are any defects such as indentation, deformation, slanting, and folding caused by improper operation methods; It is very important to explain to the operator whether the burr surface is up or down when the product is produced;
- Confirmation of product protection and placement;
- Detection of size and angle;
- Report records;
How to use the CNC press brake bending machine system
One: CNC CNC press brake bending machine method
method one:
1. Solid modeling:
2. Shell:
3. Convert to sheet metal:
Select a driving surface (that is, the central surface, or the main surface, and then select the cnc press brake bending machine line. After completion, the software automatically calculates the incision line and marks it as purple! Set the distance of the incision! (This step is not meaningful! Because the back After the ‘closed angle’ tool is used, the distance of the incision will be smoothed!) Set the appropriate CNC press brake bending machine radius (in this step, the CNC press brake bending machine radius is tried out, according to different companies, different material thickness, There are different unfolding sizes, just add it to the CNC press brake bending machine coefficient table after trying it!)
4. Further use of CNC press brake bending machine:
Further use CNC press brake bending machine, edge flange, pay attention to CNC press brake bending machine method to ensure product dimensions, (the difference between internal materials and external materials is still unknown! Khan!); Miter flanges, frills, turning, Drawn CNC press brake bending machine…!
5. Late optimization:
such as ‘closed corners’&…, after the above processing is completed, the corners are closed. The principle is that the long side encapsulates the short side, and the margin between the two contact surfaces should be considered when encapsulating. Generally 0.3mm, right, 3mm!
6. Create a drawing of a cnc press brake bending machine:
place a sheet metal unfolded drawing on the left or upper side, and a sheet metal cnc press brake bending machine drawing on the right or lower side! The cnc press brake bending machine line depends on the company’s regulations. Some companies do not require cnc press brake bending machine lines, or prohibit this thing, while some companies require cnc press brake bending machine lines, such as neutrality in cnc press brake bending machines. 0.5 percent of the face!
7. Convert to CAD drawings: 1:1
Solidworks can convert engineering drawings 1:1 into CAD drawings. Of course, it will also produce extra lines like proe, and if no detailed settings are made, its layers will not be like those set in CAD. So clear! Unifying layers in solidworks and layers in autocad is still a tough job! However, it is marked with color, font, line type, etc., and then imported into cad. In fact, it does not dive into the layer to view it. On the surface, it can still be deceived and confused! CNC press brake bending machine deduction calculation for sheet metal
