The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing:
One of them embodiment of the special-shaped clamping mould of the utility model is shown in Fig. 1 to 3; Special-shaped clamping mould mainly is made up of upper clamp formwork 1, lower clamp formwork 2 and positioner; On the working face of upper clamp formwork 1, be provided with upper pipeline die cavity 1a; On the working face of this lower clamp formwork 2, be provided with the lower pipeline die cavity 2a relative with upper pipeline die cavity 1a, when lower clamp formwork 2 closed up with lower clamp formwork 2, upper pipeline die cavity 1a docked with lower pipeline die cavity 2a to form and is the crooked pipeline die cavity 6 of 90 degree.
Referring to Fig. 4; Pipeline die cavity 6 by the first linear pattern section 61, the second linear pattern section 63 and be located at the first linear pattern section 61 and the second linear pattern section 63 between the arc line type section 62 that seamlessly transits constitute, the first linear pattern section 61 and the second linear pattern section 63 are mutually the right angle angle.The first linear pattern section 61 compared to the second linear pattern section 63 more near the mouth of pipe 3a of end to be processed.Distance between the accent of the first linear pattern section 61 and the second linear pattern section, 63 center lines is L1, and L1 is greater than 47mm.So,, pipeline fitting flared section length (length that A representes among Fig. 4) is required only need require length of straigh line to compare greater than 90 with existing pipe end moulding greater than 50mm, improved the pipeline fitting range of work greatly because the length of L1 shortens.Distance between the accent of the second linear pattern section 63 and the first linear pattern section, 61 center lines is L2, clamps for making pipeline fitting, avoids when processing and forming pipeline fitting to retreat, and L2 needs greater than 70mm.
