A kind of power lower type tie rod press

Abstract

The invention discloses A kind of power lower-mounted tie rod press, in which the combination of a motor and a screw nut is used as a power system and placed under the workbench, and a booster mechanism is set between the upper die assembly and the nut, so that the upper die set The parts can output a large output force, which is convenient for the forming and processing of the workpiece. In this way, under the condition that the tonnage of the press is required to be certain, a motor with a smaller power can be used, which not only saves energy, but also reduces costs. At the same time, the lower placement of the power system improves the stress on the base under the workbench, making it easier for the press base to meet the strength and rigidity requirements, which is conducive to shock absorption and noise reduction. At the same time, it also lowers the center of gravity of the press, thereby improving the pressure. The dynamic performance of the machine. Compared with the structures in the prior art, the structure size of the press machine can be greatly reduced, the impact force is large, the work efficiency is high, the energy utilization rate is high, the work noise is small, and the comprehensive performance is superior.

Description

technical field [0001] The invention relates to a dynamic lower-mounted tie rod press. Background technique [0002] In the field of forming processing, mechanical presses and hydraulic presses are two main processing equipments, which are used for punching, bending, stretching, extrusion and other processing of products. [0003] At present, the mechanical press widely used in China has the advantages of fast speed and high efficiency. However, since it is usually equipped with a flywheel and the power system is placed above the workbench, the asymmetry of the flywheel structure and the upper placement of the power system will lead to The center of gravity of the press is relatively high, resulting in poor mechanical properties and stability of the press, low energy utilization, large structural size, and relatively bulky appearance. In addition, the impact force of the press on the worktable is relatively large, so that the base bears a large impact force, and the vibrati...

[0003] At present, the mechanical press widely used in China has the advantages of fast speed and high efficiency. However, since it is usually equipped with a flywheel and the power system is placed above the workbench, the asymmetry of the flywheel structure and the upper placement of the power system will lead to The center of gravity of the press is relatively high, resulting in poor mechanical properties and stability of the press, and low energy utilization rate, large structural size, and relatively bulky appearance

In addition, the impact force of the press on the worktable is relatively large, so that the base bears a large impact force, and the vibration and noise are relatively large. At the same time, the base of the press needs to have high strength and rigidity. Therefore, in a certain To a certain extent, the overall size of the press is too large

[0004] However, although the widely used hydraulic presses are small in size and high in control precision, they are slow in speed and small in working strokes, resulting in low production efficiency, difficult system maintenance, easy oil leakage, and high maintenance costs.

In addition, the oil of the traditional hydraulic press achieves speed-up through the external differential circuit, but the pressure loss of the oil in the external differential circuit is relatively large, which leads to the ineffective speed-up effect of the hydraulic cylinder and increases the number of pipelines. and connection costs
