Description

Boiler ripples courage shaping frock

Technical Field

The invention relates to the technical field of boiler bellows processing equipment, in particular to a boiler bellows forming tool.

Background

The corrugated furnace pipe is an indispensable important part for forming a combustion chamber (hearth) of the pot-shell type oil and gas boiler, when the pot-shell type oil and gas boiler operates, the combustion of flame is completed in the combustion chamber (hearth), the heat absorption rate per unit area is quite high due to strong radiation heat exchange between high-temperature flame and the wall surface of the furnace pipe in the furnace pipe, the heating surface of the combustion chamber accounts for about 10-20% of the total heating surface of the boiler, but more than 60% of the total heat of the boiler is absorbed, which means that the area heat load of the heating surface is quite high; because the hearth has high thermal strength and large deformation amplitude caused by thermal expansion and cold contraction, the structure of the furnace liner is required to be particularly elastic so as to reduce the thermal stress.

The patent with the publication number of CN203484466U discloses a corrugated container forming device in the field of boiler furnace production devices, which comprises two carrier rollers horizontally mounted on a rack, the two carrier rollers are in transmission connection with a power device, a die pressing roller is arranged above the space between the two carrier rollers, two ends of the die pressing roller are respectively and rotatably mounted on shaft supporting mechanisms, the shaft supporting mechanisms are respectively connected to the end parts of piston rods of two main oil cylinders, a main oil cylinder body close to one end of the power device is mounted at the upper end of a fixed support, a main oil cylinder body far away from one end of the power device is mounted at the upper end of a rotary support, the lower end of the rotary support is hinged on the rack, the surface of the die pressing roller is in a wave shape, a press roller is arranged below the die pressing roller and is rotatably mounted at the end part of a piston rod of a lifting oil cylinder, the cylinder body of the lifting oil cylinder is mounted on the rack through a guide rail slider mechanism, and the press roller is matched with the surface of the die pressing roller. The device is convenient to process, can process continuous waves in the circumferential direction, and can be used for processing the boiler wave container.

Although this technical scheme processing is convenient, and can process out continuous wave form in the circumferencial direction, it can be used to the processing of boiler ripples courage, but the ripples courage wave form of processing out is not neat enough and even, and causes the damage of work piece very easily in the suppression, and the yields is lower, and the material is not stable enough when processing, influences the suppression of ripples courage easily.
