Description

Technical Field

[0001] The present application relates to the technical field of heater molding, and in particular to a heater armor molding machine. Background Art

[0002] A heater is an electrical appliance that uses electrical energy to achieve a heating effect. It is small in size, has high heating power, is widely used, and uses an intelligent control mode with high temperature control accuracy. It can even be connected to a computer network. The core principle of a heater is energy conversion, the most common of which is the conversion of electrical energy into thermal energy.

[0003] In the relevant technology, the processing of the heater usually includes tube making, wire winding, welding and filling, among which tube making is the most basic process in the preparation of electric heaters. The tube making machine makes steel strips of different materials into the metal outer tube of the electric heater. This process starts with the steel strip, undergoes preliminary forming, then welds, rolls into the required size, and then cuts and straightens, and a series of other processing processes.

[0004] The rolling equipment in the heater tube making process usually includes two extrusion rollers arranged opposite to each other, a support frame supporting these rollers, and a drive motor driving them to rotate. The outer circumferences of these extrusion rollers are in contact with each other, and their surfaces are also designed with special extrusion ring grooves for inserting and forming the steel strip, and the two extrusion rollers are installed inside the support frame. By accurately controlling the speed, shape and extrusion force of the extrusion rollers, the heater shape can be accurately shaped to meet diverse application requirements.

[0005] However, in actual application, this heater rolling equipment also has some problems that need to be improved. Especially after the equipment has been running for a period of time, when the extrusion roller needs to be repaired for various reasons, the existing equipment structure makes this operation relatively cumbersome. Since the extrusion roller is installed inside the support frame, it is usually necessary to dismantle the entire support frame before the extrusion roller can be removed. This process is not only time-consuming, but also complicated to operate, which seriously affects the efficiency of dismantling and inspection, and brings unnecessary troubles to the production and maintenance of heater manufacturers. Utility Model Content
