Electric drill shearing machine

Abstract

The electric drill shearing machine includes an electric screwdriver, and a shearing device is installed on the electric screwdriver. The shearing device includes a fixed arm, and one side of the fixed arm is connected to the main body of the electric screwdriver. The utility model adds a manual booster. The manual booster can facilitate personnel to manually turn the handle when the first circular cutter and the second circular cutter encounter greater resistance when shearing the metal plate. Through the transmission of the first bevel gear and the second bevel gear, a combined force is formed with the output torque of the electric screwdriver to drive the transmission shaft to rotate, thereby increasing the force to drive the first circular cutter to rotate, so that the first circular cutter and the second circular cutter can smoothly shear through the area with greater resistance.

Description

Technical Field

[0001] The utility model relates to a plate shearing machine, more specifically an electric drill plate shearing machine. Background Art

[0002] Existing electric drill shearing machines generally use lithium electric drills as driving force. Due to the limited driving force of lithium electric drills, when encountering a metal plate area where the cutter is difficult to pass, it is easy to cause the cutter to be unable to continue shearing. The personnel need to remove the shearing machine and adjust it to shear again, which is quite troublesome. For example, patent publication number: CN2644063 discloses a portable wheel knife shearing machine, such as Figure 5 As shown, this device relies solely on the driving force of an electric screwdriver for shearing. When encountering a metal plate area where the cutter is difficult to pass through, the single driving force can easily cause the cutter to be unable to continue shearing and unable to smoothly pass through the area with greater resistance. Summary of the invention

[0003] The utility model aims to provide an electric drill shearing machine, which can facilitate personnel to manually rotate the handle to form a combined force with the output torque of the electric screwdriver to drive the transmission shaft to rotate when the first circular cutter and the second circular cutter encounter greater resistance when shearing the metal plate, thereby increasing the force to drive the first circular cutter to rotate, so that the first circular cutter and the second circular cutter can smoothly shear through the area with greater resistance.
