Workpiece feeding and detection mechanism

Abstract

The invention provides a workpiece feeding and detection mechanism, and belongs to the technical field of machines. According to the workpiece feeding and detection mechanism, the problem that the feeding speed of an existing hot extrusion die opening manipulator is hard to ensure is solved. The workpiece feeding and detection mechanism is arranged at the position of a conveyor chain used for conveying workpieces, and comprises a bracket, a movable part arranged above the conveyor chain, and a sensor connected to the bracket; the movable part is movably connected to the bracket, and the lowerside of the movable part can abut against the upper side of the conveyor chain or has spacing; and the movable part can be driven to swing when the workpieces are moved with the conveyor chain, and the swing state of the workpieces can be detected by the sensor. Through the workpiece feeding and detection mechanism, the workpiece feeding can be maintained at proper speed.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a workpiece feeding detection mechanism, in particular to a high-temperature workpiece feeding detection mechanism. Background technique [0002] Red punching is a hot extrusion process that cooperates with a punching machine to realize workpiece forming. When stamping a metal workpiece, the metal workpiece needs to be heated first. After heating to the required temperature, the workpiece is placed under the punch. In the mold, the punch goes down and cooperates with the mold to stamp the workpiece. At present, the workpiece loading of the red punching process is mostly manually loaded, but due to the high ambient temperature, the work intensity is high, and the production efficiency is low. [0003] For this reason, people have designed a kind of red punch mold opening manipulator, and have applied for Chinese patent (its application number is: 201610194451.2; Its publication n...

Problems solved by technology

[0004] However, the above-mentioned red die opening manipulator lacks a device that can detect the feeding of the heated workpiece on the front conveyor chain. If the front conveyor chain is too slow, the feeding efficiency is low. If the automatic feeding is too fast, the heated workpiece If it accumulates on the front conveyor chain, it will not only cause the heat loss of the workpiece after heating, affect the processing quality of the punching machine, but also may cause the feeding of the automatic feeding device at the heating furnace to be stuck
