Abstract

The invention provides a punch press safety braking device. A punch press comprises a machine body and a large gear thereof. A clutch key handle is arranged in the large gear; a catch wheel is arranged on one side, corresponding to the clutch key handle, of the machine body; a pedal is further arranged on the lower part of the machine body; a transmission mating component is arranged between the pedal and the catch wheel; the pedal controls rotation of the catch wheel via the transmission mating component; when the catch wheel is in touch with the clutch key handle in the rotation process, a crankshaft is thereby controlled to rotate to work, so a slide block of a machine tool ceases to move; when the catch wheel is separated from the clutch key handle in the rotation process, a clutch isbonded, and the crankshaft rotates to drive a connecting rod, a punch rod and the slide block on the punch press to conduct pressing operation up and down; the transmission mating component comprisesa pedal rod; the pedal is fixedly arranged on the pedal rod; a compression spring is arranged on the pedal rod; and the pedal rod presses on the compression spring. The punch press safety braking device can effectively replace a traditional tension spring structure and avoid the phenomenon that the spring is prone to fatigue or fracture or is stretched in long-term application and thereby affectsnormal resetting of the catch wheel. Continuous punching by the punch press, occurrence of damage to a die, or personal safety accidents are effectively prevented.

Description

technical field [0001] The invention relates to a safety braking device for a punch press. Background technique [0002] The existing safety braking device for punching machines is generally provided with a tension spring at the pedal, one end of the tension spring is connected to the pedal, and the other end of the tension spring is connected to the connecting rod. Even the phenomenon of fracture leads to unreliable safe operation of the operator and endangers the safety of the operator's life and property; causes the buyer to compensate the operator's life and property, and then makes the buyer pursue the responsibility of the manufacturer and seller through legal channels. When the negotiation fails, it has to be resolved in court, and legal disputes arise between manufacturers and sellers, resulting in entanglement in lawsuits. Therefore, manufacturers must make further improvements. [0003] In addition, Chinese Patent Document No. CN104802446A discloses a ratchet bra...
