Problems solved by technology

In the existing bending machines, the bending is done directly, but for the evaporator that needs to be bent multiple times, such as the "凵" shape, and the straight line in the middle of the two bends is shorter, when bending the second time, the first bending The bent end is in a free state. When bending for the second time, due to the large bending force, there will be stress acting on the bent end, which will make the bending inaccurate and damage the evaporator at the same time
And the existing bending machine is positioned by manual loading and positioning, which brings a lot of errors

Abstract

The invention relates to a bending machine, which comprises a frame. A rotating roller and a rotating roller driving mechanism are arranged on the frame, an upper pressing plate and a lower pressing plate rotating along with the rotating roller are arranged on the rotating roller, and a clamping control device for controlling clamping heat exchangers of the lower pressing plate and the upper pressing plate is arranged between the lower pressing plate and the upper pressing plate. The bending machine is technically characterized in that a lifting mechanism is further arranged on the frame, a lifting platform is arranged on the lifting mechanism, a bending follow-up platform is arranged on the lifting platform, a reset power device is arranged on the bending follow-up platform, a positioning mechanism is arranged at one end of the bending follow-up platform, a positioning power mechanism is arranged on the positioning mechanism, a clamping device and a horizontal power device are further arranged on the frame, an upper clamping plate, a lower clamping plate and a vertical power device are arranged on the clamping device, a clamping power device is arranged between the upper clampingplate and the lower clamping plate, a top side plate mechanism is arranged on one side of the lower pressing plate, a top side plate mechanism pushing device is arranged on the top side plate mechanism, and a feeding plate is further arranged on one side of the lower pressing plate. The bending machine can be used for improving precision of multiple bending and realizing automatic positioning.

Description

【Technical field】 [0001] The invention relates to a bending machine. 【Background technique】 [0002] A heat exchanger is a heat exchange device that transfers part of the heat of the hot fluid to the cold fluid so that the temperature of the fluid reaches the index specified in the process, also known as a heat exchanger. Generally, heat exchangers can be used as heaters, coolers, evaporators, etc. In the manufacturing process of the heat exchanger, the accuracy of the bending process directly affects the heat transfer performance of the heat exchanger. In the existing bending machines, the bending is done directly, but for the evaporator that needs to be bent multiple times, such as the "凵" shape, and the straight line in the middle of the two bends is shorter, when bending the second time, the first bending The bent end is in a free state. When bending for the second time, due to the large bending force, there will be stress acting on the bent end, which will make the be...
