The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As Fig. 1, Fig. 2 and shown in Figure 3, the gripping mechanism of plug in the cold pilger mill of the present invention, comprise: the main fuselage that constitutes by support 16 and shell 3, be movably set with hollow shaft 2 in the shell 3, be set with gripping sleeve 9 on the hollow shaft 2, offer the locating slot 91 of annular on the outer wall of gripping sleeve 9, offer three oblique T type chutes of evenly arranging 92 on the inwall of gripping sleeve 9, be respectively arranged with slide block 10 in three T type chutes 92, each slide block 10 is connected with by three bolts that a claw 11---its structure is referring to shown in Figure 5, like this, each slide block 10 and corresponding claw 11 have just formed the T type structure that matches with T type chute 92---referring to shown in Figure 6, three claws 11 are located in respectively in three claw holes 21 on hollow shaft 2 tube walls---and the structure of hollow shaft 2 is referring to Fig. 7, shown in Figure 8, hollow shaft 2 also offers annular groove 22---referring to shown in Figure 7, be provided with the spacing snap ring 12 that matches with claw 11 in the annular groove 22, also be provided with the stop collar 13 that matches with gripping sleeve 9 on the hollow shaft 2; Shell 3 is provided with bearing 7, bearing 7 is provided with hydraulic cylinder 6, and be hinged with a pair of fork 8 by connecting axle 34, this upper end to fork 8 is set together by the piston rod of hinge 38 with hydraulic cylinder 6, this inboard to fork 8 lower ends is provided with bearing pin 31, concrete set-up mode is: an end of bearing pin 31 is located in the lower end of fork 8, and fix by screw 30 and fork 8, be provided with bearing 33 on each bearing pin 31, this a pair of bearing 33 is fastened in the locating slot 91 of gripping sleeve 9, and the central lines of the center line of this a pair of bearing pin 31 and gripping sleeve 9---referring to shown in Figure 4.
Operation principle of the present invention is as follows: Hydraulic Station is by 6 actions of solenoid control hydraulic cylinder, hydraulic cylinder 6 drives fork 8 swings by hinge 38, the pair of bearings 33 of fork 8 lower ends promotes gripping sleeve 9 and seesaws, make the slide block 10 in the T type chute 92 that is installed in gripping sleeve 9 slide with respect to T type chute 92, because slide block 10 is fixed together by bolt and claw 11, and the spacing snap ring 12 that claw 11 is set in the annular groove 22 of hollow shaft 2 blocks, can not move axially, like this, slide block 10 just changes into the radial motion of claw 11 with respect to the axially-movable of gripping sleeve 9, thereby realizes the purpose that claw 11 opens or clamps.After claw 11 clamps plug 18, cold pilger mill is just started working, gear shaft 1 rotates under the driving of power set, the rotation of gear shaft 1 by the travelling gear 15 on the gear shaft 1, with the transmission of the driven gear 5 of travelling gear 15 engagements, drive rotates by the hollow shaft 2 that flat key 4 and driven gear 5 are set together, and hollow shaft 2 drives gripping sleeve 9, claw 11 again and the plug 18 that is located in the hollow shaft 2 rotates together.
