Discharge mechanism of sheet metal shearing machine

Abstract

The invention relates to a discharge mechanism of a sheet metal shearing machine. The discharge mechanism comprises a slowdown motor, a conveying belt, an electromagnet and two roll shafts; one of the two roll shafts is fixedly mounted at the discharge side of a shearing die while the other one is fixedly mounted at the entrance of the next work position; the conveying belt is sleeved outside the two roll shafts; the slowdown motor is connected to the roll shaft and drives the roll shafts to rotate; the electromagnet used for increasing surface friction between a board material and the conveying belt is fixedly mounted at the lower side of the conveying belt. As the on-off time and the magnetic size of the electromagnet arranged in a discharged material conveying device are controlled, on one hand, the conveying speed is guaranteed, and on the other hand, the relative friction between the surface of the board material and the conveying belt is reduced to the maximum extent, and accordingly the surface quality is protected.

Description

technical field [0001] The invention relates to a metal sheet shearing machine, in particular to a discharge mechanism of the metal sheet shearing machine. Background technique [0002] The metal sheet shearing machines currently on the market usually use the feeding system to send the sheet into the shearing die, and then the shearing die sets the action in advance to process the sheet, and then the sheet is sent to the In the next process, the shearing dies of the metal sheet shearing machine with this structure can only be used for special dies, that is, a set of dies can only process sheets of one specification and shape. If it is necessary to process sheets of other specifications and shapes It is necessary to change the mould, which not only requires a large amount of moulds, but also affects the production efficiency in the production process. For this reason, the applicant of the present invention has invented a shearing machine with a swingable shearing die. Traditi...

[0002] The metal sheet shearing machines currently on the market usually use the feeding system to send the sheet into the shearing die, and then the shearing die sets the action in advance to process the sheet, and then the sheet is sent to the In the next process, the shearing dies of the metal sheet shearing machine with this structure can only be used for special dies, that is, a set of dies can only process sheets of one specification and shape. If it is necessary to process sheets of other specifications and shapes It is necessary to change the mould, which not only requires a large amount of moulds, but also affects the production efficiency in the production process. For this reason, the applicant of the present invention has invented a shearing machine with a swingable shearing die. Traditional shearing machines generally only produce For a plate of one shape, only the friction between the conveyor belt and the plate in the discharge system can meet the conveying requirements, but the swingable shearing machine can cut out plates of different shapes according to the needs, and the difference between plates of different shapes and the conveyor belt The required conveying friction is different, and the traditional discharge system can no longer meet the high-speed production requirements. Therefore, the improvement of the discharge system has become an urgent requirement.
