Embodiment 1

[0045] 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.

[0046] 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 perfor...

Embodiment 2

[0051] 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

[0053] A method for pressing a bending machine, the steps are as follows:

[0054] 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;

[0055] 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 die stamping method of a bending machine and belongs to the field of manufacturing of bending machines. The bending machine for die stamping includes flat die stamping bodies, the section of each flat die stamping body is concave, protrusions on the two sides of each flat die stamping body are die stamping shoulders, the concave part in the middle of each flat die stamping body is a die stamping inner bottom, and multiple blind holes are formed in each die stamping inner bottom and internally provided with magnets completely matched with the blind holes in size; eachflat die stamping body is composed of multiple independent die stamping segments, and by separately detecting the position and area of a to-be-flatten part of each to-be-flatten component, the lengthof each to-be-flatten segment is calculated; according to the length of the to-be-flatten segments, multiple segments of flat die stamping bodies different in length are manufactured, the corresponding flattening frequency is resolved, and each group of flat die stamping bodies required in flattening each time are separately installed and flattened. The bending machine has the advantages of beingsimple in structure and easy and firm in installation, the flattening precision is high, the flattening effect is great, and flattening can be carried out on a specific position.

Description

[0001] When applying for the patent of the present invention, the divisional application with the application number: 2016106442599, the application date of the original application is: 2016-8-8, and the name of the invention is: a bending machine compression mold, a bending machine and a compression molding method. technical field [0002] The invention relates to the field of bending machine manufacturing, and more specifically, relates to a method for pressing a bending machine. Background technique [0003] 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. Th...
