Automatic feeder for punch

Abstract

The invention relates to an automatic feeder for a punch, belonging to the field of punching equipment of flaky material parts. The invention particularly relates to an automatic feeding mechanism for a punch, which is used for carrying out subsequently punch forming for many times on flakes subjected to punch forming once. The automatic feeder comprises a stand (1), a stand regulating mechanism, a stacking plate (6), a supporting frame (5), a pushing and feeding mechanism and a power transmission mechanism, wherein the stand regulating mechanism is installed at the bottom of the stand (1), the stacking plate (6) is arranged at the front end of the stand (1), the supporting frame (5) is arranged below the stacking plate (6), and the pushing and feeding mechanism and the power transmission mechanism are arranged above the stacking plate (6). The automatic feeder is characterized in that two pushing arms (9) are fixed at the front end of a sliding comprehensive support (13) side by side; two feeding arms (14) are respectively fixed at the left side and the right side of the sliding comprehensive support (13); the feeding arms (14) comprise an upper clamping part (23) and a lower clamping part (24); bidirectional transmission shafts (20) are respectively arranged at the tail ends of the upper clamping part (23) and the lower clamping part (24); gears are correspondingly arranged on the two bidirectional transmission shafts (20); and an upper gear and a lower gear are meshed to drive the upper clamping part (23) and the lower clamping part (24) to rotate oppositely. The automatic feeder of the invention can automatically push and feed materials safely and synchronously together with the punch, can be directly driven by the working power of the punch, does not need an additional power source, and has the advantages of energy saving and high efficiency.

Description

technical field [0001] The utility model relates to an automatic feeding machine for a punching machine, which belongs to the field of stamping processing equipment for sheet materials, and specifically relates to an automatic feeding mechanism for a punching machine when a thin sheet formed by one stamping is subsequently stamped and formed multiple times. Background technique [0002] After the raw materials are punched into sheet-like semi-finished products once by a punching machine, they also need to be processed and formed by subsequent multiple punches. In most cases of the existing feeding process of subsequent stamping processing, the operator directly feeds the material to the stamping die by hand during the stamping feeding process. Practice has proved that this manual feeding method is not efficient, and the operator requires Strict, secondly, the safety factor of manual feeding is not high, and it is not uncommon for operators to be injured and disabled in the s...

In most cases of the existing feeding process of subsequent stamping processing, the operator directly feeds the material to the stamping die by hand during the stamping feeding process. Practice has proved that this manual feeding method is not efficient, and the operator requires Strict, second, the safety factor of manual feeding is not high, and it is not uncommon for operators to be injured and disabled in the stamping feeding process; third, manual feeding, the operator's work intensity is high

[0003] Chinese patents 200810022260.3 and 200820169017.X both involve roller feeding technology. Practice has proved that this type of feeding mechanism feeds for a long time, and the single feeding does not meet the requirements of various specifications of the workpiece to be punched.
