Lifting and balancing device for hot press

Abstract

A lifting and balancing device for a hot press comprises two baseplates, two balance tooth racks and two connecting seats which are symmetrically arranged, as well as a balance bar, wherein the baseplates are arranged on the base of the hot press; symmetric shaft holes are formed in the baseplates; bearings are arranged in the shaft holes; the balance bar is arranged on the two baseplates through the two bearings; gears are fixedly arranged at the two ends of the balance bar; the two connecting seats are symmetrically arranged on the bottom surface of a working table of the hot press; the top ends of the two balance tooth racks are hinged on the corresponding connecting seats, the two balance tooth racks are parallel to each other; the gears at two ends of the balance bar are meshed with the corresponding balance tooth racks. As the balance tooth racks of the lifting and balancing device can swing, abrasion or damage caused by too larger stress on the gears and the balance tooth racks as well as increased error of the balancing device can be avoided, level stability of the working table as well as processing precision of plank can be ensured, and the lifting stability of the working table can be ensured since guide rollers can enable the gears to roll stably on the balance tooth racks.

Description

technical field [0001] The invention relates to a balancing device, in particular to a lifting balancing device for a heat press. Background technique [0002] The hot press is mainly used for the pressing of plates. The material between the hot plates is pressed into plates through the lifting of the workbench. In order to ensure the uniform thickness of the plates, the workbench needs to be kept level during the rising process, and the workbench needs to be equipped with a balance device. Currently The balance device used is mainly composed of gears, racks, and balance bars. The racks are directly connected to the workbench. When the workbench moves up and down and there is a horizontal deviation, the force on the racks and pinions increases, which is prone to wear and even damage. , causing the error of the balance device to increase, so that the workbench cannot be kept level, and the machining accuracy is reduced. Contents of the invention [0003] The present invent...
