Abstract
The utility model relates to a kind of U-shaped pipe bending shoe for heat exchanger tube, this mold mainly contains the parts such as fixed platform, driving wheel, fixed wheel and forms, the heat exchanger tube that will bend penetrates between fixed wheel and driving wheel, utilize connecting plate to drive driving wheel, around fixed wheel, move in a circle, heat exchanger tube one end is blocked with backing pin, and heat exchanger tube, due to stress deformation, is bent into straight tube the U-shaped pipe of drawing requirement.The utility model not only can be enhanced productivity, and traditional-handwork simmering and bending are controlled and are also significantly improved the appearance and size precision of U-shaped heat exchanger tube relatively simultaneously, and this mold has versatility.
Description
Technical field
The utility model relates to the manufacturing and processing equipment of heat exchanger, especially in order to solve the simmering and bending under production requirement of heat exchanger tube and seamless steel pipe, is shaped.
Background technology
Along with the pipeline structure of heat exchanger tube bend pipe is constantly brought forth new ideas and the continuous increase of product type, use traditional manual bend pipe to carry out bend pipe work, efficiency is low, and exists the defect of pickup difficulty.Due to the particularity of U-shaped heat exchanger, its heat exchanger tube used is U-shaped, needs cooperation processing aborning in U-shaped heat exchanger tube, and the cycle is long, and expense is high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of U-shaped pipe bending shoe for heat exchanger tube
,to reach the object that improves bend pipe operating efficiency, solve heat exchanger tube and the bright o ing of seamless steel pipe under production requirement.
The heat exchanger tube that this utility model will bend penetrates between fixed wheel and driving wheel, utilizes connecting plate to drive driving wheel, around fixed wheel, moves in a circle, heat exchanger tube one end is blocked with backing pin, heat exchanger tube, due to stress deformation, is bent into straight tube the U-shaped pipe of drawing requirement, and its technical scheme is as follows:
1.U shape heat exchanger tube pipe bending shoe is comprised of rectangular metal platform, driving wheel, fixed wheel, backing pin, circular hole, square hole, upper junction plate, lower connecting plate, fixed wheel fixed connecting piece, driving wheel fixed connecting piece;
2. on platform, there is the square hole coordinating with fixed wheel, on platform, have the circular hole coordinating with backing pin, circular hole and square hole appearance and size in platform, distance of center circle size is certain;
3. square hole is unique, and circular hole is to have several, Heterogeneous Permutation;
4. fixed wheel appearance and size bends change in radius with heat exchanger tube and changes, it coordinates because being connected location with fixed wheel fixed connecting piece with square hole, with heat exchanger tube, bend the circular hole that change in radius selects it to coordinate, fixed wheel fixed connecting piece has respectively upper junction plate lower connecting plate to be connected up and down with it up and down, and now not only fixedly lower connecting plate is gone up in fixed wheel but also connection to fixed wheel fixed connecting piece;
Upper junction plate lower connecting plate both support the use, connecting plate plate body has driving wheel positioning round orifice, by driving wheel fixed connecting piece location driving wheel, its appearance and size is specific, the change in radius with U-shaped heat exchanger tube does not change;
6. the centre-to-centre spacing between the fixed wheel being attached thereto is to meet to bend the corresponding theoretical chi of heat exchanger tube radius, and driving wheel and fixed wheel between the two diameter and the heat exchanger tube external diameter that will bend of groove are suitable.
Accompanying drawing explanation
Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 are U-shaped heat exchanger tube pipe bending shoe device schematic diagrames.Its digital concrete meaning is respectively: 1. platform, 1-2. backing pin circular hole, 1-3. square hole, 2. upper junction plate, 2-1. driving wheel positioning round orifice, 3. driving wheel, 4. fixed wheel, 5. lower connecting plate, 5-1. driving wheel positioning round orifice, 6. fixed wheel fixed connecting piece, 7. backing pin, 8. driving wheel fixed connecting piece
The specific embodiment
On a metal platform face, requirement platform surface is smooth, on platform, there are the circular hole and the square hole that match with fixed wheel and backing pin, it is characterized in that locating fixed wheel and backing pin, fixed wheel is allowed to condition at and on metal platform face, is not produced displacement by fixed wheel fixed connecting piece, upper lower connecting plate connects fixed wheel fixed connecting piece and fixed wheel, thereby driving wheel becomes an interlinked mechanism, the heat exchanger tube that will bend penetrates between fixed wheel and driving wheel, utilize connecting plate to drive driving wheel, around fixed wheel, move in a circle, backing pin is that the heat exchanger tube that penetrates of location is allowed to condition at one end in the process of bending and does not produce displacement, guarantee the formation of U-shaped pipe.Thereby the U-shaped heat exchanger tube that meets different radii by the change of fixed wheel self size, the radius of fixed wheel is just equivalent to the radius of U-shaped heat exchanger tube, can produce and meet the crooked requirement of 6.3.4.1 to U-shaped heat exchanger tube in GB151-1999.
Claims (1)
1. the U-shaped pipe bending shoe for heat exchanger tube, it is characterized in that mold is by rectangular metal platform, driving wheel, fixed wheel, backing pin, backing pin circular hole, square hole, upper junction plate, lower connecting plate, fixed wheel fixed connecting piece, driving wheel fixed connecting piece forms, on rectangular metal platform, there is the square hole coordinating with fixed wheel, on platform, there is the backing pin circular hole coordinating with backing pin, fixed wheel fixed connecting piece is by the fixing fixed wheel of square hole, and be fixedly connected with lower connecting plate simultaneously, both support the use upper junction plate lower connecting plate, connecting plate body has driving wheel positioning round orifice, hole is by driving wheel fixed connecting piece location driving wheel, the appearance and size of fixed wheel is to select corresponding fixed wheel size with heat exchanger tube simmering and bending change in radius, and driving wheel appearance and size is immovable, in the distance changing between fixed wheel size while connecting plate plate body driving wheel positioning round orifice and square hole, also changing, centre-to-centre spacing between driving wheel and fixed wheel meets will bend the corresponding theoretical chi of heat exchanger tube radius, driving wheel and the fixed wheel between the two diameter of groove are suitable with the heat exchanger tube external diameter that will bend, and described mold has the square hole coordinating with fixed wheel.
