Safety protection device for aluminum alloy plate cutting machining

Abstract

The invention relates to the technical field of aluminum alloy material machining equipment, and discloses a safety protection device for the aluminum alloy plate cutting machining. The safety protection device comprises a workbench, a rotating shaft is movably connected into the workbench, a first chain wheel fixedly sleeves the rotating shaft, a chain is engaged with the exterior of the first chain wheel, and a connecting rod is movably connected with the exterior of the chain; a sliding rod is movably connected to the outside of the connecting rod, and a sleeve rod is movably connected to the outside of the sliding rod; through interaction among a connection rod, a shell, a limiting block, an electro-rheological body, an electric wire, a movable block, a speed reducing block, a first spring, a second spring and a monitoring assembly, the rotating speed of a lead screw can be limited in time when the rotating speed of the lead screw exceeds a normal speed range due to stall of a motor in the aluminum alloy plate cutting machining process; and the rotating speed of the lead screw is gradually reduced, so that the situation that the cutting blade is broken due to the fact that themoving speed of the lead screw is too high is avoided, and meanwhile continuous cutting of an aluminum alloy plate is not affected.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy material processing equipment, in particular to a safety protection device for aluminum alloy plate cutting and processing. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. [0003] The aluminum alloy plate needs to be cut during the production process. However, the existing cutting device is not equipped with a safety protection device. During the cutting process of the aluminum alloy plate, due to current overload or some accidental factors, the As a result, the rotation speed of the motor suddenly becomes faster, and at the same time, the rotation speed of the screw rod also becomes faster and exceeds the normal speed range of aluminum alloy plate cutting. At this time, the fast rotation of the scr...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a safety protection device for aluminum alloy plate cutting and processing, which can timely correct the screw rod when the motor fails or the rotation speed of the screw rod exceeds the normal range due to operator error. The advantages of deceleration and the ability to fix the aluminum alloy plate stably during the cutting process solve the problem that the motor failure causes the rotation speed of the screw to exceed the normal range, making the cutter move too fast during the cutting process, resulting in the emergence of cutting pieces The situation of collapse and the problem of unstable fixing of the aluminum alloy plate during the cutting process
