How to avoid sheet metal processing errors

How to avoid sheet metal processing errors

Jul 19, 2020

Sheet metal processing is a precision processing technology that can process various metal materials. The products processed by this processing method have high precision, smooth surface, good appearance and high quality. To process this high-precision sheet metal part, it is necessary to do various tasks during processing, and to avoid processing errors and processing errors during processing. So what do I need to pay attention to to avoid errors in processing? How can I make processing errors free? Let's take a look.

First of all, do a good job of reviewing the drawings, the drawings can not be wrong, if there is a mistake, the subsequent series of work will go wrong. We must carefully review the drawings. To do: check the drawings for omissions in the specifications and the status of the specifications. Examine whether the drawing and the parts list (opening, opening specification list), whether the shape specifications and quantity are the same, whether the opening specifications on the parts list are correct, whether the cutting quantity is correct, and whether the materials of the plates used are consistent with the drawings At the same time as the requirements, are there any missing parts opening specifications on the parts list.

Second, the use of shears. Whether the correction office of the parts list has a signature for review, if not, it is not allowed to cut the material. Check carefully what kind of material is required on the parts list. When cutting the entire large plate, the operation process corresponds to the specification of the parts list and cut from large to small. When cutting cold-rolled plates, pay attention to which specification plate is used to cut the least remaining data, and which specification is preferred Sheet cutting

Third, do a good job of cutting and punching. Check whether the information, quantity and specifications of the cut plates are correct. Open the specifications on the corresponding parts list and check whether the cutting specifications are correct, whether the quantity is the same, and whether the sheet material is consistent with the drawing requirements. Adjust the backer according to the requirements of the drawings. Preliminary cutting, punching, and punching. The first block is self-inspected. If the quantity exceeds 5 blocks, the first block of each standard needs to be inspected by the quality inspector, and the punching can only be performed after passing the signature. . The punching is finished and classified, the ones that require direct bending are transported to the vicinity of the bending machine, and those that require CNC punching are transported to the vicinity of the CNC punching machine.
