[utility model content]
In view of this, for overcoming the deficiencies in the prior art, the utility model provides a kind of steel wire rope drum inner ring bending mould, and it is applicable to prevent turning round bending of steel wire rope drum, and the distortion of drum inner ring is little.
A kind of steel wire rope drum inner ring bending mould, described steel wire rope drum inner ring bending mould comprises upper die and lower die, described patrix and described counterdie mutually close up seamless steel pipe are bent to steel wire rope drum inner ring, the contact-making surface that bends of described patrix is cylindrical arc, the contact-making surface that bends of described counterdie is interior circular arc, and the diameter of the circular arc that bends contact-making surface that bends contact-making surface, described counterdie of described patrix is identical with drum inner ring diameter to be processed.
In at least one preferred embodiment, the radian of the circular arc that bends contact-making surface that bends contact-making surface, described counterdie of described patrix is 60 ° therein.
Therein at least one preferred embodiment, the bending of contact-making surface, described counterdie that bend of described patrix is provided with respectively on contact-making surface accordingly for accommodating and upper pressure port and the lower pressure port of shaping steel tube, the lateral cross of described upper pressure, described lower pressure port is circular arc, and the slightly larger in diameter of the circular arc of the lateral cross of described upper pressure, described lower pressure port is in the external diameter of steel pipe to be bending.
In at least one preferred embodiment, the radian of the circular arc of the lateral cross of described upper pressure, described lower pressure port is 150 ° therein.
In at least one preferred embodiment, described steel wire rope drum inner ring bending mould fluid,matching press 20 uses therein, before using, described patrix is connected to hydraulic press top panel by bindiny mechanism 24, and described counterdie is connected on hydraulic press lower panel.
In steel wire rope drum inner ring bending mould of the present utility model, by the product of different size being configured targetedly to the mould of dimension, to adapt to the product processing of different size, radian and the deflection of control product that also can be very strict, guaranteed the quality of drum inner ring.
[accompanying drawing explanation]

Fig. 2 A, 2B are respectively steel wire rope drum inner ring bending mould in Fig. 1 main TV structure schematic diagram and the side-looking structural representation under use state.
[specific embodiment]
In order to understand better the utility model, below with reference to accompanying drawing and instantiation, the utility model is described in detail.
Turn round to seamless steel pipe moulding is anti-the drawback that steel wire rope drum brings in order to improve traditional bending technique, the utility model provides a kind of special steel wire rope drum inner ring bending mould, and mould specific is for steel wire rope drum inner ring bending mould.
Incorporated by reference to consulting Figure 1A and Figure 1B, the steel wire rope drum inner ring bending mould 10 that preferred embodiment of the present utility model provides comprises patrix 12 and counterdie 14, and patrix 12 and counterdie 14 mutually close up seamless steel pipe is bent.The contact-making surface that bends of patrix 12 is cylindrical arc, and the contact-making surface that bends of counterdie 14 is interior circular arc, and radian is 60 °, and the diameter of circular arc is identical with the drum inner ring diameter of processing.The bending of upper and lower mould 12,14 is provided with respectively on contact-making surface accordingly for accommodating and upper pressure port 120 and the lower pressure port 140 of moulding seamless steel pipe.The lateral cross of upper pressure port 120, lower pressure port 140 is circular arc (as shown in Figure 1B), and the radian of circular arc is 150 °, and the slightly larger in diameter of circular arc is in seamless steel pipe external diameter to be bending.
Above-mentioned drum inner ring bending mould 10 can arrange sizes specification, selects according to the size of drum inner ring.
Incorporated by reference to consulting Fig. 2 A and Fig. 2 B, above-mentioned drum inner ring bending mould 10 fluid,matching press 20 use.Before use, patrix 12 is secured by bolts in special bindiny mechanism 24, syndeton 24 adopts bolt to be connected with hydraulic press top panel 22, and counterdie 14 is connected on hydraulic press lower panel 26.
In the time bending steel wire rope inner ring, first by seamless steel pipe one end on the lower pressure port 140 as for counterdie 14, primer fluid press 20 slowly compresses patrix 12 downwards.In the time that upper and lower mould 12,14 and seamless steel pipe compress completely, the i.e. extrusion molding of this section of seamless steel.Remaining seamless steel pipe is continued to carry out according to the method described above segmentation compacting, be finally pressed into an annulus completing.Finally with electric welding machine by firm the joint weld at annulus two ends, a satisfactory drum inner ring machines.
Compared with prior art, steel wire rope drum inner ring bending mould of the present utility model at least has the following advantages:
