Abstract

The invention discloses a linear drive high-speed press. A linear motor - switch flux permanent magnet linear motor with a novel topological structure is adopted to drive a press punch to perform straight reciprocating motion. The motor and a secondary promoter connected with the punch are simple in structure, and structural damage to a permanent magnet caused by continuous impact load of the press can be avoided. The press punch is light in inertia and quick in dynamic responses such as acceleration and deceleration, startup and shutdown and the like, the permanent magnet and an armature winding are fixed to a press body, the demagnetization risk of the permanent magnet is reduced through a cooling system, the electromagnetic load density of the motor is increased, and thus motor thrust and stamping force of the press are improved. The armature winding and the permanent magnet only exist within a primary effective length of the motor outputting thrust, the usage amount thereof is greatly reduced, and the motor manufacturing cost is reduced. In addition, a cylinder is arranged to be connected with the punch, so that an air pressure force and the electromagnetic thrust of the motorjointly act to serve as stamping force, and the press tonnage is greatly improved.

Description

technical field [0001] The invention belongs to the field of high-speed presses, in particular to a linear-driven high-speed press. Background technique [0002] The number of strokes of the slider of the high-speed press is generally more than 200 times per minute. The higher the number of strokes of the slider, the larger the adjustable speed range of the drive transmission system is required. At present, most of the transmission mechanisms of high-speed presses are multi-link mechanisms of various forms, which can increase the speed of the slider during the idle stroke while reducing the working stroke speed of the slider, thereby achieving the purpose of improving production efficiency. However, the multi-link high-speed press puts forward very high requirements on vibration noise, friction coefficient, body stiffness, dynamic accuracy of bottom dead center and braking performance. In particular, it is necessary to design a reasonable dynamic balance mechanism to balanc...
