Cooling bed lifting type translation mechanism

Abstract

The invention relates to a cooling bed lifting type translation mechanism. The translation mechanism comprises a movable frame, a lifting frame is arranged above the movable frame, a left connecting beam and a right connecting beam are arranged above the lifting frame, a plurality of front translation beams and a plurality of back translation beams are arranged between the left connecting beam andthe right connecting beam, a left guide assembly and a right guide assembly are arranged on the lifting frame, a left roller assembly and a right roller assembly are arranged at the bottom of the left connecting beam and the bottom of the right connecting beam respectively, the left guide assembly and the right guide assembly are matched with the left roller assembly and the right roller assemblyrespectively, and a translation oil cylinder assembly is arranged on the lifting frame and connected with the connecting beams. The multiple front and back translation beams are connected together through the connecting beams, and the piston rod ends of the translation oil cylinders are buckled with the connecting beams through buckling claws, so that the multiple translation beams are driven totranslate synchronously, the tooth jumping phenomenon is avoided, manual adjustment is not needed, the production efficiency is greatly improved, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to a lifting type translation mechanism of a cooling bed, which belongs to the technical field of aluminum profile production equipment. Background technique [0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot-melting and extruding aluminum rods. The production process of aluminum profiles mainly includes three processes: casting, extrusion and coloring. At present, in the metal pressure pipe rod profile extrusion workshop, the cooling bed in the auxiliary machine after the extruder cools the extruded aluminum profile and transports it to each subsequent station. [0003] The translational mechanism of the existing cooling bed such as figure 1 As shown, it is driven by a transmission shaft along the front and rear directions, and a plurality of transmission gears are arranged at intervals on the transmission shaft, an upper transmission rack is arranged at the bottom of the tra...

AI Technical Summary

Problems solved by technology

[0003] The translation mechanism of the existing cooling bed is as follows: figure 1 As shown, it is driven by a transmission shaft along the front and rear directions, and a plurality of transmission gears are arranged at intervals on the transmission shaft, an upper transmission rack is arranged at the bottom of the translation beam, a translation cylinder is provided on the lifting frame, and the piston rod end of the translation cylinder is connected. There is a lower transmission rack, the upper transmission rack and the lower transmission gear are both meshed with the transmission gear, and the translation cylinder drives the translation beam through the rack and pinion mechanism to perform translation movements. This method is more suitable for the transportation of lighter aluminum profiles, but For large aluminum profiles with heavy weight, due to the inevitable bending of the aluminum profiles to a certain extent, there is a phenomenon of uneven force on the front and rear translation beams, resulting in different wear degrees of the front and rear racks. Tooth skipping phenomenon is easy to occur, and manual auxiliary adjustment is required, which greatly reduces production efficiency. When the tooth skipping phenomenon is serious, it may even be stuck, which is easy to cause damage to parts and affect the service life of the equipment; in addition, there is a wedge at the bottom of the lifting frame. There is a driving roller at the end of the piston rod of the lifting cylinder, and the driving roller cooperates with the wedge-shaped plate to make the lifting frame go up and down. However, when transporting large aluminum profiles, the driving roller is prone to slipping and deviation when lifting the wedge-shaped plate. , requires manual assistance, reduces production efficiency and affects the surface quality of aluminum profiles
