Abstract: The present invention relates to a manufacturing method of a handle for agricultural machineries and, more particularly, to a manufacturing method of a handle for agricultural machineries which can reduce fraction defective due to spring back by reducing a spring-back effect. The manufacturing method of the handle for agricultural machineries according to the present invention comprises a handle ring manufacturing step and a support welding step. In the handle ring manufacturing step, a handle ring is manufacturing by bending a square steel pipe with a bending machine having the 5% smaller diameter than the handle ring while tensing the square steel pipe with the 35% load among the bending force of the bending machine. In the support welding step, supports are welded on the handle ring. The present invention can reduce the spring back effect to reduce the fraction defective due to the spring back when manufacturing the handle ring. Accordingly, the present invention can obtain not a manual work by field workers but precisely continuous forming and automated processing technology on handle parts for various agricultural machineries. Also, the present invention establishes mass-production and independent technology using an automated forming device.
Abstract translation: 本发明涉及一种用于农业机械的手柄的制造方法，更具体地，涉及一种农业机械的把手的制造方法，其可以通过减少回弹效应来减少由于弹回而导致的部分缺陷。 根据本发明的农业机械手柄的制造方法包括手柄环制造步骤和支撑焊接步骤。 在手柄环制造工序中，通过弯曲具有比手柄环的直径小5％的弯曲机的方形钢管来制造把手环，同时在弯曲的弯曲力中以35％的载荷拉紧正方形钢管 机。 在支撑焊接步骤中，支撑件焊接在手柄环上。 本发明可以减少弹簧回复效果，以便在制造把手环时减少由于弹回而导致的部分不良。 因此，本发明不能获得现场工作人员的手工作业，而是可以在各种农业机械的手柄部件上精确地连续成型和自动加工技术。 此外，本发明使用自动化成形装置建立大规模生产和独立技术。
