Bending machine basics

Bending machine basics

●The function of the bending machine: The bending machine is a kind of equipment for processing the plate into various angles; after adding the numerical control function, the machining precision and production efficiency are effectively improved.

●Common bending machine tool classification.

1.Punch:

2.Die:

●Segmentation of bending tools:

Under normal circumstances, the length of the tool is 835mm. In order to facilitate different lengths of bending, the whole length of the tool is often divided into the following segments: 10+15+20+40+50+100+200+300=835

●Correspondence between plate thickness and groove width:

Conventionally, the groove width is 6 times the plate thickness.

● Regular bending sequence:

1. Short side and long side first: Generally speaking, when there are bends on all four sides, folding the short side and then folding the long side is beneficial to the processing of the workpiece and the assembly of the bending mold.

2. First, the middle and the middle: Under normal circumstances, it is generally folded from the periphery of the workpiece to the center of the workpiece.

3. Partially after the whole: If there are some structures inside or outside the workpiece that are different from other bending machines, generally bend these structures and then fold the other parts.

4. Consider the interference situation and arrange the bending sequence reasonably: the bending sequence is not static, and the processing sequence should be adjusted according to the shape of the bending or the obstacle on the workpiece.

●Note on bending operation:

1. When bending operation, always pay attention to personal safety, need to pay attention to the following points:

  1.0When the device is turned on, do not extend from the edge of the bending machine to adjust the back gauge; you should go directly to the back of the device to adjust.

  1.1When processing parts, the human body should be outside the range of the parts to avoid the parts being scraped into the human body.

  1.2When processing large parts, the human body is best to stand on the side of the workpiece and operate on one side.

  1.3The workpiece should be supported at all times to avoid damaging the workpiece or injuring the human body.

  1.4The human body should stand firm during operation and cannot affect the balance of the body due to the movement of the workpiece.

  1.5When operating close to the knife edge, the hands must be placed in the proper position of the lower mold to prevent the fingers from protruding into the knife edge.

  1.6The removed tool can't be placed on the bending machine, nor can it be placed on the bending machine to prevent the tool from falling and hurting the human body.

  1.7When installing the tool, make sure that the upper and lower molds are separated after the tool has been tightened.

  1.8When disassembling the tool, it is necessary to hold the tool with both hands to separate the upper and lower molds.

  1.9Consider wearing protective shoes.

  2.When bending operation, pay attention to ensure the integrity of the mold and equipment;

  2.1When installing the tool, always pay attention to the gap between the upper and lower molds needs to be within the normal range.

  2.2When installing the tool, make sure that the upper and lower molds are separated after the tool has been tightened.

  2.3After the mold is installed, it is necessary to check whether the lower mold is fastened in time to avoid damage to the tool due to the displacement of the lower mold.
