Embodiment 1

[0044] Such as figure 1 , 2 As shown, a bending machine die includes a flat die die body 1, the flat die die body 1 has a concave cross-section, 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 slide block 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 magnets 3 which completely match the size of the blind holes are arranged in the blind holes. The flat mold compression mold body 1 is composed of several independent compression mold sections, and magnets 3 are arranged at equal intervals on each section. The magnet 3 is a neodymium-iron-boron magnet. The neodymium-iron-boron magnet is the permanent magnet with the strongest magnetic force so far. It has high cost perfo...

Embodiment 2

[0050] A bending machine with the pressing die of the bending machine in Embodiment 1, the width of the end 6 of the slider of the bending machine is the same as the width of the inner bottom 4 of the pressing die, the body 1 of the flat die pressing die is adsorbed to the end 6 of the sliding block, It is fixed on the end 6 of the slider, and there is no gap between the flat die body 1 and the slider 5 . For irregular parts to be flattened, the bending machine is used for flattening, and the flat die is installed with magnets. The installation is fast, the stability is good, there will be no deviation during work, and the work progress is fast. Multi-segment flat dies are used for different parts The area and length of the flattening area are flattened, the quality is good, and the progress is fast, which avoids the consequences of one-time flattening and deformation of other parts caused by independent flattening, and also overcomes the fact that the entire flat die can only ...

Embodiment 3

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

[0053] A) The parts that need to be flattened in the detection need to be flattened and the size of the area. The part enters the end of the bending machine as the calculation, and the calculated flattened position corresponds to the position of the slider 5 and the flattened position of each section. The required flattening length of slider 5;

[0054] For example, if a car door panel needs to be flattened, there are five points that need to be flattened, and none of them are on a straight line. According to 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 D is the area with a length of 6cm, point D is the 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, and if a single flattening machine is...

Abstract

The invention discloses a bending machine die and a bending machine, which belong to the field of bending machine manufacturing. A bending machine die, including a flat die body, the flat die body has a concave cross-section, the protrusions on both sides are the shoulders of the die, the middle recessed part is the inner bottom of the die, and the inner bottom of the die is There are a number of blind holes, and magnets that completely match the size of the blind holes are installed in the blind holes. The flat mold die body is composed of several independent die sections. The flattening position and area of ​​the components that need to be flattened are detected through decomposition. size, calculate the required flattening length of each section; according to the required flattening length, make several sections of flat die bodies of different lengths, decompose the corresponding number of flattening times, and calculate the number of groups of flat die bodies required for each flattening. , install and flatten in stages. It has the advantages of simple structure, simple installation, firm installation, high flattening accuracy, good flattening effect, and can be flattened at specific locations.

Description

technical field [0001] The invention relates to the field of bending machine manufacturing, more specifically, to a bending machine die and a bending machine. Background technique [0002] A bending machine is a machine that can bend thin plates. Now people have various requirements for bending machine products. When a sheet metal bending machine is processed, it uses a mold to process the sheet into various shapes, so it is necessary to have Mold bodies with various structures are matched, and the design requirements of the general mold body are easy to process and form at one time. Bending machines are used to form tools for processing sheet metal. 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 through the change of the physical state of the formed material. A tool used to turn a blank into a workpiece of a specific shape and size under the pressure of a bending ma...
