Description

Split type furnace end

Technical Field

The utility model relates to a burning heating technical field, concretely relates to furnace end structure for on fireplace.

Background

The development of fireplaces, from the middle of the 16 th century to the 20 th century, is on the one hand the history of fire utilization by people, with coal, gas and electricity being implemented on fireplaces, thus making the use of fireplaces more efficient, comfortable and convenient. Meanwhile, the fireplace is always in the core position of indoor European style decoration style, and various fireplaces convey life concepts and fashion concepts of people in various times. The fireplace is a heating facility of an indoor space, and has quite wide market prospect and user foundation at present. The inventor of this patent application has been dedicated to the improvement of fireplace, take the fireplace that burns combustible gas as an example, and the product that prior art related to is very much, through investigating and discovering that there is a core component named furnace end in current fireplace, the following weak point exists in general structurally, namely: the furnace end is the integral type structural design who adopts more, because the furnace end has the part of bending, consequently the wall thickness need be done thickly when the design, satisfies the requirement of bending, otherwise breaks easily, and the design of being forced the thickening leads to increasing the cost. In addition, need process a plurality of fire holes on the furnace end, the integral type structure has not good location when punching, problem that the spoilage is high.

In summary, a furnace head structure with thinner tube wall, more convenient operation during processing and lower production cost is lacking at present.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a split type furnace end that the pipe wall is thinner, and it is more convenient to operate man-hour, and manufacturing cost is lower.

In order to solve the technical problem, the utility model provides a technical scheme does: a split type furnace end is a bent pipe formed by connecting an upper half pipe and a lower half pipe through riveting, wherein one end of the bent pipe is an open pipe head, the other end of the bent pipe is a closed pipe tail, and the upper half pipe is provided with two fire holes, namely a round hole and a long hole; the edge of the joint of the upper half pipe and the lower half pipe is provided with a press riveting edge.

Preferably, the bent pipe formed by riveting the upper half pipe and the lower half pipe is integrally of a U-shaped structure, a row of round holes are formed in the bending part of the U-shaped bent pipe, and two rows of long holes are formed in the straight pipe section, close to the pipe head, of the U-shaped bent pipe; two sections of long holes are arranged on the straight pipe section of the U-shaped bent pipe close to the pipe tail, and a section of round hole is connected between the two sections of long holes.

Preferably, the press riveting edges of the upper half pipe and the lower half pipe are provided with paired positioning protrusions and recesses.

After the structure is adopted, the utility model discloses following beneficial effect has: the furnace end is creatively arranged in a split way, and the two split parts are connected by adopting the press riveting, so that the pipe wall of the furnace end can be thinned, and the cost is saved. In addition, when the round hole and the long hole are machined, machining can be completed on the upper half pipe firstly, and then riveting is carried out, because the machining is carried out on the half pipe, better positioning and operation are realized, the damage rate is lower, and the problem that the pipe is directly punched when the hole is punched does not exist. The positioning structure in the preferred design further increases the convenience in processing and can realize the quick positioning between the upper half pipe and the lower half pipe.

To sum up, the utility model provides a pipe wall is thinner, and it is more convenient to operate man-hour, lower split type furnace end of manufacturing cost.
