  1, Pipe bends stamping, generally no chip broken material generated, less material consumption, and do not need other heating equipment, it is a kind of material, machining method of energy saving, stamping parts of the cost is low.

  2, Pipe bends stamping due to the size and shape of mold to ensure the stamping precision, and generally does not destroy the surface of the stamping quality pipe quantity, and the life of the mould are long, so the stamping quality is stable, good compatibility, has the characteristics of "the same".

  3, Pipe bends stamping processing of high production efficiency, and easy to operate, easy to realize mechanization and automation. This is because the stamping is rely on die and stamping equipment to complete the processing, ordinary press stroke times per minute can reach dozens of times, high pressure to can reach more than hundreds of times or even one thousand times per minute, and every time stamping stroke might get a shock.

  Four, Pipe bends stamping machining size range is larger, more complex shape parts, such as small to watch the stopwatch, big to auto longeron, covering parts, etc., and stamping material hardening effect of cold deformation, the strength and stiffness of stamping was high.

  Pipe bends caused the main reason for the decline in the quality analysis of the cause Pipe bends is the main reason for the decline in the quality analysis and pay attention to methods. Moment M under the action of pure Pipe bendsing, pipe and outer wall of the lateral arm of sex subjected to tensile stress & 1 and thinning, the inside of the compressive stress. And thickening, together to N1 and N2 changes make the pipe cross section. Based on this factor, causes the decrease of the quality of the bent pipe main original because the RX and SX so GBJ235-82, RX value of under various pressure levels and thinning of the lateral mass were made clearly defined, the purpose is to control the value of RX and SX, to ensure the quality.

  Pipe bends when the material of the lateral tensile, compression of hangzhou Pipe bends when it comes to the medial location of neutral axis is different and Pipe bends method, when he worked in top Pipe bendsing type (compression Pipe bendsing) neutral axis in about 1/3 place, from the outer wall in spiral curved (Pipe bends), neutral axis in two-thirds from the outer wall. So thin wall Pipe bends, the use of rotary Pipe bendsing method is useful. The precision of the Pipe bendsing of tire is one of the factors affecting the quality of Pipe bends.

  The flexible function of pipe itself and surface erosion, may also affer the quality of Pipe bends. Site construction is also necessary for the operator to understand was processing of the pipe material, processing function and to determine on the production surface erosion.
