Blocking finger device of bending machine

Abstract

The invention discloses a blocking finger device of a bending machine. The blocking finger device of the bending machine comprises blocking finger driving devices arranged on the left side and the right side of the bending machine. A pair of blocking fingers are arranged between the blocking finger driving devices on the left side and the right side side by side. The blocking finger driving devices on the left side and the right side drive the two blocking fingers to move between the left side and the right side. Each blocking finger comprises a blocking finger slider arranged on a Z axis slide rail of the bending machine in a sliding manner. The blocking finger sliders are provided with sliding grooves in the front and back direction. A blocking finger base is arranged in each sliding groove in a sliding manner. The blocking finger sliders are provided with blocking finger front and back micro adjustment devices so that the front and back positions of the blocking finger bases in the sliding grooves can be adjusted. The front ends of the blocking finger bases are connected with a front blocking finger through floating pin shafts. The blocking finger sliders are provided with horizontal adjusting device so that the horizontal position of the front blocking finger can be adjusted. According to the blocking finger device of the bending machine, the blocking fingers have the overall accurate micro adjustment function, and therefore the risk of industrial injuries is avoided to the maximum extent, meanwhile, cost is controlled, and positioning precision is guaranteed.

Description

[0001] The patent application of the present invention is a divisional application of the invention and creation title "An Automatic Finger Locking Mechanism for Bending Machine". The original application date is May 12, 2014, and the application number is 2014101981616. technical field [0002] The invention relates to a bending machine, in particular to a finger stop mechanism of a bending machine. Background technique [0003] 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. [0004] 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 mec...

AI Technical Summary

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.

[0005] 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
