Automatic stop finger mechanism of bending machine

Abstract

The invention discloses an automatic stop finger mechanism of a bending machine, which comprises stop finger drive devices arranged on the left side and the right side of the bending machine, wherein a pair of stop fingers is arranged side by side between the stop finger drive devices on the left side and the right side; drive shafts are axially equipped with driving wheels and driven wheels; the driving wheels are fixed with the drive shafts; drive belts are arranged between the driving wheels and the driven wheels on the drive shafts on the left side and the right side; the two drive belts are fixed with the two stop fingers respectively and drive the two stop fingers to move between the left side and the right side respectively; stop finger fore-and-aft fine adjustment devices for adjusting fore-and-aft positions of stop finger bases in slide grooves are arranged on stop finger slide blocks; the front end of each stop finger base is connected with a front stop finger via a floating pin shaft; and horizontal adjustment device for adjusting horizontal positions of the front stop fingers are arranged on the stop finger slide blocks.The mechanism achieves semi-automatic control of a stop finger Z-axis mechanism, and allows the stop fingers to have an overall precise fine adjustment function, so that a risk of work injuries are avoided to the full extent, the cost is controlled at the same time, and the locating accuracy is ensured.

Description

technical field [0001] The invention relates to a bending machine, in particular to a finger stop mechanism of a bending machine. Background technique [0002] In the development of bending machine technology, as the requirements for production efficiency continue to increase, there are more requirements for fast and stable positioning through the fingers. [0003] Among the back gauge mechanisms of bending machines currently on the market, there are the following Z-axis mechanisms for the fingers, one is a manual Z-axis mechanism, and the other is a servo Z-axis mechanism. The manual Z-axis mechanism is currently the most widely used, but it needs to manually enter the working area of ​​the back gauge mechanism to manually adjust the position, which has the risk of work-related injuries, and the positioning accuracy is low. Although the servo Z-axis mechanism reduces the risk of industrial accidents for workers and improves positioning accuracy and digital control, the cos...

Problems solved by technology

The manual Z-axis mechanism is currently the most widely used, but it needs to manually enter the working area of ​​the back gauge mechanism to manually adjust the position, which has the risk of work-related injuries, and the positioning accuracy is low

Although the servo Z-axis mechanism reduces the risk of industrial accidents for workers and improves positioning accuracy and digital control, the cost has increased several times, and most customers do not approve of such a cost.

[0004] Moreover, the back of the finger does not have a fine-tuning function, and the front surface is generally designed to be in one-plane contact, which is not conducive to the adjustment of the finger and the zero point of the machine tool during the debugging process, and it is even more unfavorable to realize the precise fine-tuning function
