Problems solved by technology

[0003] The workpiece of the heat exchanger is usually placed horizontally on the worktable for bending, and the feeding device releases the workpiece during bending. After the first bending is completed, the workpiece is clamped for feeding, and then the second bending is performed. Bending, it takes a certain amount of time to clamp and then loosen, resulting in a longer working cycle, which affects the bending efficiency, especially on workpieces with a large number of bending times.
Moreover, there are many types of heat exchanger workpieces, and the existing bending mechanism cannot adapt to this situation

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] Such as figure 1 As shown, a vertical bending machine includes a fuselage 1, a bending mechanism, a follower plate 4, a feeding device 6, and a working table mounted on the fuselage.

[0035] Image 6 It is the bending mechanism of the vertical bending machine in this embodiment, and its bending die rotation mechanism is the first servo motor 203 with the first reducer, and the end of the first reducer output shaft 207 of the first servo motor 203 is installed with the bending die 2. The output shaft 207 is supported by bearings in the bending die sleeve 205, and the first servo motor 203 is fixed on the bending die sleeve 205 through the connecting flange 206, so the first servo motor 203 can drive the output shaft 207 to rotate independently, thereby Drive the bending die 2 fixed on the output shaft 207 to rotate, but the bending di...

Abstract

The invention discloses a vertical bending machine which comprises a machine body, a workbench plate arranged on the machine body, a bending mechanism and a follower plate. The bending mechanism is vertically arranged on the workbench plate. The follower plate is arranged in a workpiece feeding direction of the bending mechanism. In time of bending, a workpiece is limited by the follower plate and the bending mechanism. The follower plate and the bending mechanism act synchronously. As two rotation mechanisms are used, a bending mold can be independently rotated, and a material pressing plate and the bending mold can be rotated at the same time. Bending precision is improved and the bending mold can be independently rotated so that restoring is convenient. Multiple bending of a workpiece is facilitated, bending efficiency is greatly improved, application range is wide and quality of the workpiece can be improved.

Description

technical field [0001] The invention relates to a vertical bending machine, in particular to a bending machine capable of bending a vertically placed heat exchanger. Background technique [0002] The bending machine is used to bend the heat exchanger into G shape, U shape or L shape, and it is the key equipment for heat exchanger forming. [0003] The workpiece of the heat exchanger is usually placed horizontally on the worktable for bending, and the feeding device releases the workpiece during bending. After the first bending is completed, the workpiece is clamped for feeding, and then the second bending is performed. Bending, it takes a certain amount of time to clamp and then loosen, resulting in a longer working cycle, which affects the bending efficiency, especially on workpieces with a large number of bending times. Moreover, there are many types of heat exchanger workpieces, and the existing bending mechanism cannot adapt to this situation. Contents of the inventio...
