Abstract

The invention relates to a main transmission mechanism of a servo numerical control rotary head press, wherein two electrical motors with middle torque and small inertia are connected to a precise ball screw with large lead by a safety coupler mounted in a bracket and with a pulse unloading function; a small angle rolling wedge driving mechanism, a screw nut and a ball guide rail slider are fixed together; a ball guide rail and a rack are fixed; a wedge drives a roller and a punch to move up and down; and the two electrical motors are controlled by a synchronous driving method. The mechanism related by the invention can be used for improving the rigidity, transmission precision, fatigue life, abrasive resistance and high-speed servo impact carrying capacity of the main transmission overall mechanism, and reducing the friction of the transmission system and the lateral load of the punch; by using the two electrical motors with middle torque and small inertia, the requirements of carrying and high dynamic response are satisfied synchronously; the key performance for accelerated reciprocating movement of the system can be ensured; the selection difficulty of the servo driving electrical motor and the manufacture cost of the whole machine are reduced; and the plurality of electrical motors are driven synchronously, so that the feasibility for realizing large-tonnage drive systems is improved.

Description

technical field [0001] The invention relates to a main transmission mechanism of a servo numerical control rotary head press. Background technique [0002] Servo numerical control rotary head press is a kind of stamping equipment that can complete the automatic conveying of sheet metal, automatic replacement of dies and high-efficiency precision processing of sheet metal. It is suitable for continuous high-speed servo punching of thin plates. Its basic features are high efficiency, high precision, energy saving, environmental protection and automation, which represent the development direction of CNC rotary head presses. [0003] At present, the stamping main drive of the CNC rotary head press mostly adopts a high-speed hydraulic punch system or an ordinary motor mechanical main drive. As long as the CNC rotary head press with a hydraulic main drive or an ordinary motor mechanical main drive is turned on, the main motor will Non-stop operation, idling consumes more power. ...
