Embodiment 1

[0044] like figure 1 , 2 As shown, a press brake die for a bending machine includes a flat die press die body 1, and the flat die press die body 1 is a concave cross-section, and the protrusions on both sides are die shoulders 2, and the inner shoulders of the die shoulders 2 are The inner corner 7 is chamfered to avoid damage caused by the collision between the die shoulder 2 and the slider 5 during installation.

[0045]The middle concave part is the inner bottom 4 of the compression mold, and the inner bottom 4 of the compression mold is provided with a number of blind holes, and the blind holes are provided with magnets 3 that completely match the size of the blind holes. The flat die body 1 is composed of several independent die segments, and magnets 3 are arranged on each segment at equal intervals. The magnet 3 is a NdFeB magnet. The NdFeB magnet is a permanent magnet with the strongest magnetic force so far. It is cost-effective, has good mechanical properties, and h...

Embodiment 2

[0050] A bending machine with the bending machine press die of Example 1, the width of the slider end 6 of the bending machine is the same as the width of the inner bottom 4 of the press mold, and the flat die press body 1 and the slider end 6 are adsorbed, It is fixed on the slider end 6, and the flat die body 1 and the slider 5 have no gap. For the irregular parts to be flattened, the bending machine is used for flattening, and the flat die pressing die installed by the magnet is used. The installation is fast, the stability is good, the deviation will not occur during work, and the work progress is fast. Use multi-stage flat die to target different parts The flattening area of ​​area and length is flattened, the quality is good, and the progress is fast, which avoids the consequences of the deformation of other parts caused by the flattening caused by the independent flattening, and also overcomes the fact that the entire flat die can only press the regular parts. Flat, the...

Embodiment 3

[0052] A method of pressing a bending machine, the steps are as follows:

[0053] A), the flattening position and area size of the parts that need to be flattened for testing, take the part entering the bending machine as the calculation, and calculate the position of the flattening corresponding to the position of the slider 5 and the flattening position of each section The required flattening length of the slider 5;

[0054] If there is a need to flatten a car door panel, there are five points that need to be flattened, and none of them are on a straight line. Through our calculations, point A is an area with a length of 10cm, point B is an area with a length of 5cm, and point C is an area with a length of 5cm. Point is an area with a length of 6cm, point D is an area with a length of 10cm, point E is an area with a length of 15cm, and points A, B, and C are on a straight line, and points D and E are on a straight line. When flattening point A, due to the streamlined design...

Abstract

The invention discloses a bending machine pressing die, a bending machine and a die pressing method, and belongs to the field of bending machine manufacturing. The bending machine pressing die comprises flat die pressing die bodies. The section of each flat die pressing die body is concave. Protrusions on the two sides of each flat die pressing die body are pressing die shoulders. A sunk part in the middle of each flat die pressing die body is a pressing die inner bottom. Each pressing die inner bottom is provided with a plurality of blind holes. Each blind hole is internally provided with a magnet of which the size is completely matched with that of the blind hole. The flat die pressing die bodies are composed of a plurality of independent pressing die sections; the position needing to be pressed and the area size of components needing to be pressed are detected in a disintegrated mode, and the length needing to be pressed of each section is calculated; and the multiple sections of flat die pressing die bodies of different lengths are manufactured according to the length needing to be pressed, the number of corresponding pressing times is disintegrated, and batch installation and pressing are conducted on the group number of the flat die pressing die bodies needed by pressing each time. The bending machine pressing die has the advantages of being simple in structure, easy to install and firm in installation, is high in pressing precision and good in pressing effect and can conduct pressing on specific positions.

Description

technical field [0001] The invention relates to the field of bending machine manufacturing, and more particularly, to a press brake die for a press brake, a press brake and a press die method. Background technique [0002] A bending machine is a machine that can bend thin plates. Nowadays, people have various requirements for bending machine products. When a sheet metal bending machine is processed, a die is used to process the sheet into various shapes, so it is necessary to have For the mold bodies of various structures, the general design requirements of the mold body are convenient for one-time processing. The bending machine is a tool used to form and process sheet materials. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. A tool used to make a blank into a part of a specific shape and size under the pressure...
