Reinforcing device

Abstract

The invention discloses a reinforcing device, which includes a base (18), a ball screw (16) arranged on the base (18) and sleeved with a ball nut (15), a thrust block (17) connected with the ball nut (15) and provided with a wedge structure and an inclined surface angle no bigger than 45 DEG, a reinforcing block (25) arranged on the inclined surface of the thrust block (17) through an inclined rolling guide pair (24), and a servomotor (11) used for driving the ball screw (16). In the device, as the servomotor, the ball screw pair and the wedge structure are effectively combined, a small driving force is input and a big output force is achieved for reciprocating movement, as a result, the problems of the driving power source and the transmission device that the structure is complicated and the energy consumption is big are overcome, and the reinforcing device has a simple structure, is simple to calculate the reinforcing ratio, and can realize the precise control of the displacement, the velocity and the output force in the precise forming machinery.

Description

technical field [0001] The invention relates to the technical field of power devices, in particular to a booster device. Background technique [0002] In many occasions, it is necessary to output a large force (several tons, hundreds of tons to thousands of tons or even tens of thousands of tons) to complete a job, such as presses (mechanical presses, hydraulic presses, screw presses, flat forging machines, and stamping machines) , straightening machine, shearing machine, forging manipulator), injection molding machine, static pressure pile machine and friction welding machine, etc. However, the power that the driving power source can provide is limited, so some devices are needed to increase the power. The existing active driving methods mainly include hydraulic and mechanical, and the mechanical also includes the servo. Compared with the full hydraulic, it does not use the hydraulic system but uses the motor and the mechanical structure to realize energy saving and enviro...

AI Technical Summary

Problems solved by technology

However, the bearing capacity of the ball screw is limited after all, and the price is expensive. The development of low-cost heavy-duty high-efficiency precision screw pair has become one of the problems to be solved urgently for servo forming equipment.

One way out is to develop heavy-duty rolling screw, but its carrying capacity is still not enough for large-scale forming equipment with hundreds of tons to thousands of tons; the second is to develop a new type of high-efficiency heavy-duty precision sliding screw pair
