Problems solved by technology

The commonly used method is to force it to yield into an arc through the fixture for heat setting. The existing fixture assembly methods are all manual assembly. Because a lot of physical strength is required during assembly, the fixture assembly consistency is poor, and the thermoformed After the product pass rate is very low

Abstract

Disclosed is an arc-shaped spring forming machine. The arc-shaped spring forming machine comprises a first spring positioning device, a second spring positioning device, a third spring positioning device, a first air cylinder, a second air cylinder, a third air cylinder, a fourth air cylinder, a fifth air cylinder, a sixth air cylinder and a seventh air cylinder. An ejection rod of the first air cylinder and an ejection rod of the second air cylinder are relatively stretched out to be arranged. The first spring positioning device and the second spring positioning device are distributed at the two sides of a connecting line of the ejection rod of the first air cylinder and the ejection rod of the second air cylinder and are each provided with a rotating center. The ejection rod of the second air cylinder is connected with the third spring positioning device. An ejection rod of the third air cylinder is connected with the first spring positioning device, and an ejection rod of the fourth air cylinder is connected with the second spring positioning device. The fifth air cylinder is arranged between the first air cylinder and the third air cylinder. The sixth air cylinder is arranged between the first air cylinder and the fourth air cylinder. The first spring positioning device is provided with a spring loading inlet, and the seventh air cylinder is located by the side of the fourth air cylinder. By means of the arc-shaped spring forming machine, arc-shaped springs can be automatically produced in a high-efficiency mode.

Description

technical field [0001] The invention relates to a spring forming machine and a spring forming method, in particular to an arc spring forming machine and an arc spring forming method. Background technique [0002] The widespread application of springs diversifies the structure and shape of the springs. For example, a large number of arc springs are used in automobile dual-mass flywheels and hydraulic torque converters. Due to the great difference in shape and structure between arc springs and ordinary helical compression springs, the existing equipment in mass production cannot directly produce qualified arc spring products. Since the existing coil spring equipment can only produce common inline-shaped helical compression springs, the shape of arc springs in the world is formed by reprocessing. The commonly used method is to force it to bend into an arc through the fixture for heat setting. The existing fixture assembly methods are all manual assembly. Because a lot of physi...
