Problems solved by technology

[0003] However, when stamping with a stamping die, the screw rod that adjusts the stamping stroke will often loosen due to the vibration generated by stamping, which will cause the stamping stroke to be too large, causing quality problems of the stamping parts, and seriously causing the punch to break and the abrasive tool to be damaged

Abstract

The invention discloses an electrical protection device of a numerical control machine tool. An adjustment connecting rod, a locking device, a crankshaft, a sliding block and a switch assembly are arranged on a rack. The crankshaft is rotatably arranged on the top of the rack. The sliding block is rotatably arranged on the crankshaft. The locking device is arranged on the bottom surface of the sliding block. The adjustment connecting rod is in threaded connection with the interior of a threaded hole in the middle of the sliding block. The switch assembly is fixed to the sliding block. Throughthe electrical protection device provided by the invention, during operation of a punching machine, a lock nut on the stroke adjustment connecting rod gets loose, a clutch and a brake device are started immediately to stop motion of a punch pin. Accordingly, the situation that the punch pin fractures and a grinding tool is damaged due to the excessive punching stroke is prevented, and the productquality of the punching machine is ensured.

Description

Technical field [0001] The invention relates to the technical field of punch equipment, in particular to the electrical protection device of a numerical control machine tool. Background technique [0002] In modern production, the stamping process has the advantages of saving materials and energy, higher efficiency than traditional mechanical processing, low technical requirements for operators, and making products that cannot be achieved by mechanical processing through various mold applications. Its uses are becoming more and more extensive, and its application range in various industries is also extremely wide. The design principle of the punch press is to convert circular motion into linear motion. The main motor drives the flywheel and drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to rotate through the clutch to achieve the linear motion of the slider. [0003] However, when stamping with a stamping die, the screw that adjusts the stamping stroke is of...
