Specific embodiment

Referring to Fig.1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 make the utility model.A kind of double drives for forging hot-working are vertical to expect to turn over Turn pincers, including tong arm 1, chela 2, hinge 3, secondary chain sling 4, secondary suspension ring 5, main chain sling 6 and main suspension ring 7, the middle part of two tong arms 1 lead to It is hinged to cross hinge 3, the lower end of each tong arm 1 is fixed with two chelas 2, the upper end of two tong arms 1 pass through respectively main chain sling 6 with Main suspension ring 7 connects, and the lower end of two tong arms 1 is connect by secondary chain sling 4 with secondary suspension ring 5 respectively, and the master that main suspension ring 7 is located at driving hangs On hook, secondary suspension ring 5 is located on the secondary suspension hook of driving, it is characterised in that: two chelas 2 of 1 lower end of tong arm are equipped with folder Hold device 8；The front end of the clamping device 8, including positioning seat 81, shaft 83, chuck 84 and positioning column 85, positioning column 85 is solid Surely it is equipped with chuck 84, the middle part of positioning seat 81 is equipped with through-hole 82, and the rear end of positioning column 85 is inserted into through-hole 82, and the two of positioning seat 81 Side is fixed with shaft 83 respectively, and the outer end of shaft 83 is located in the groove of ipsilateral chela 2.In actual processing, positioning The shaft 83 of seat 81 and two sides is processed into an entirety, and chuck 84 and positioning column 85 are processed into an entirety.

The rear end of the positioning column 85 is equipped with transverse holes, and locking pin 86 is inserted into transverse holes, in the rear end of positioning column 85 It after being inserted into and being pierced by the through-hole 82 of positioning seat 81, is inserted into locking pin 86 in the transverse holes of 85 rear end of positioning column, thus will positioning Column 85 is fixed on positioning seat 81, prevents positioning column 85 from slipping from positioning seat 81.

The outer end of the shaft 83 is fixed with bar 10, and the outer wall of ipsilateral chela 2 is equipped with and 10 phase of bar The free end of two limited blocks 11 of adaptation, bar 10 is located between two limited blocks 11, limits gear by two limited blocks 11 The rotation angle of bar 10, to finally limit the rotational angle of shaft 83.

It is equipped with the fixed plate 9 for stopping shaft 83 on the outside of the groove of the chela 2, prevents shaft 83 from the groove of chela 2 Inside fall off.

The front bulkhead of the chuck 84 is equipped with anti-skid chequer 87, increases contact surface coefficient of friction, avoids handling process Middle ingot blank slips, and causes safety accident.

In forging hot procedure, when lifting by crane the steel ingot heated using the utility model, as long as two clamping devices 8 Chuck 84 be moved slightly away from the intermediate position of ingot blank and clamped, that is to say, that retaining part is lifted by crane close to mouth of a river end, by The positioning column 85 at 84 rear portion of chuck for clamping ingot blank when steel ingot base vice jaw part weight ratio mouth of a river end weight, lifting can be in positioning column It rotates in 81 through-hole 82, so that ingot blank jaw be made to sling downward, ingot blank is erected, turning steel ingot blank is freely fast Jumping-up process is finally completed in victory under press.The utility model can be reduced the lifting time of jumping-up process, and quickly vertical material, guarantees Blank jumping-up under the high temperature conditions achievees the purpose that guarantee that quality extends forging time and improves production efficiency.
