Description

Convex and Concave Movable Corrugated Plate Forming Device

technical field

The utility model relates to a metal forming device, in particular to a forming device for metal corrugated plates.

Background technique

Corrugated plates are widely used in various fields of industry and daily life. The main purpose is to process metal plates into regular waves to increase the rigidity and strength of the body. Especially in the field of combustion, corrugated plates are often used To increase the area and improve the heat dissipation efficiency. Due to the different shapes, sizes and requirements of corrugated plates in different industries, their processing techniques are different, but there are two problems: one is that it is easy to produce plastic indentations or pull marks on the surface of the corrugated plates after rigid pressing, and the other is corrugated after forming. Insufficient pitch accuracy and uneven sheet thickness. For this reason, it is often necessary to adopt a post-processing process to eliminate plastic indentations or pull marks by grinding or painting, which will inevitably increase the process and increase the cost, especially for the board with relatively small size and dense corrugation. For the change of corrugated pitch during forming, it is often realized by one-time forming or natural shrinkage, which often leads to the deterioration of the surface quality of corrugated plates or the dimensional accuracy cannot meet the requirements.

The beneficial effects of the utility model are:

(1) The positioning die of the upper die can slide left and right, and is guided by a linear guide rail. The ball body reduces the movement resistance and ensures the flexibility of the positioning die; the positioning punch of the lower die can not only slide left and right, but also follow the straight line The guide rail body moves up and down, and keeps consistent with the left and right sliding of the upper die positioning die, so as to better adapt to the corrugation pitch change problem in the forming process.

(2) The flexibility of the positioning die and the positioning punch reduces or eliminates the relative movement of the sheet metal and the punch and die during the forming process, reduces the contact resistance, and effectively reduces or eliminates the forming indentation and surface tension. It can greatly improve the surface quality of the corrugated board.

(3) The characteristic of the end of each section of corrugation is that the forming die is in close contact with the positioning die, and the forming punch is in close contact with the positioning punch. This device can well guarantee this feature, so it can achieve accurate corrugation pitch. control.

(4) Moving the positioning die and the positioning punch can also correct the waveform and improve the accuracy of the waveform size and shape.
