Heating device for hydraulic tray welding machine

Abstract

The invention discloses a heating device for a hydraulic tray welding machine, which comprises two aluminium plates. A steel plate is sandwiched between the two aluminium plates; both front and reverse surfaces of the steel plate are respectively provided with a plurality of U-shaped grooves; and U-shaped heating strips in fit with the U-shaped grooves are arranged in the U-shaped grooves. According to the scheme adopted by the scheme, the U-shaped grooves and the U-shaped heating strips are arranged on both the front and reverse surfaces of the steel plate, so that the heating and temperature rising speed is high, the temperature rising process is stable, the heating and heat dissipating efficiency is high; meanwhile, due to the arrangement of the U-shaped grooves on the steel plate, when the U-shaped heating strips are damaged, the U-shaped heating strips are convenient to replace; and the steel plate is sandwiched between the two aluminium plates, so that the thermal conductivity is good and the U-shaped heating strips are also well covered by the aluminium plates, and therefore, the contact between the U-shaped heating strips and the air is reduced, the oxidability of the contact between the U-shaped heating strips and the air is reduced and the service life of the U-shaped heating strips is prolonged.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating device for a hydraulic pallet welding machine. Background technique [0002] The heating device on the existing tray welding machine mainly includes a base and a heating plate connected to the base. From the perspective of usage, this heating method has problems such as slow temperature rise, low heat transfer efficiency, and uneven temperature distribution. shortcoming. Contents of the invention [0003] In view of the above-mentioned existing technical problems, the object of the present invention is to propose a heating device for a hydraulic pallet welding machine with fast temperature rise and high efficiency. [0004] The technical solution of the present invention is achieved in the following way: a heating device for a hydraulic pallet welding machine, comprising two aluminum plates; the two aluminum plates are sandwiched with inner steel plates; the front and back surface...
