specific Embodiment approach 1

[0025] Specific implementation mode one: as Figure 1 to Figure 6 , Figure 10 ~ Figure 14 As shown, the heated steel pipe is hoisted and turned over by its own weight, which includes a clamping frame assembly 1, a pneumatic mechanism assembly 3 and two clamping head assemblies 2; the clamping frame assembly 1 includes a gas distribution valve seat 1-1, a cylinder seat 1-2, clamping arm connecting seat 1-3, lifting ring 1-4, clamping arm shaft 1-6, connecting sleeve 1-8, connecting sleeve 1-9 and two clamping arms 1-12; pneumatic mechanism Component 3 includes air source conduit 3-1, gas reversing valve 3-2, cylinder left air guide pipe 3-4, cylinder right air guide pipe 3-5 and cylinder 3-6;

[0026] Two clamping arms 1-12 are all made of vertical arm and oblique arm, and the upper end of vertical arm is connected with the lower end of oblique arm, and the arm length of oblique arm is shorter than the arm length of vertical arm; Two clamping arms 1 -12 is arranged relative ...

specific Embodiment approach 2

[0027] Specific implementation mode two: as figure 1 , Figure 7 ~ Figure 9 As shown in the specific embodiment 1, the heating steel pipe lifting self-weight flipping pneumatic clamper described in the first embodiment, the two clamping head assemblies 2 both include a clamping head 2-1, a bearing cover 2-2, and a sleeve 2-3 , bearing 2-4, nut 2-6 and clamping head shaft 2-8; the cross section of clamping head 2-1 is rectangular, the middle part of clamping head 2-1 is provided with a shoulder hole, and the outer part of bearing 2-4 The ring is installed in the shoulder hole of the clamping head 2-1, one end face of the clamping head 2-1 is detachably connected with the bearing cap 2-2 by screws, and the processing of the other end face of the clamping head 2-1 There are two trapezoidal grooves 2-1-1, and the two trapezoidal grooves 2-1-1 are arranged in a cross; that is, the two trapezoidal grooves 2-1-1 of the clamping head 2-1 are separately arranged on the clamping head 2...

specific Embodiment approach 3

[0028] Specific implementation mode three: as Figure 4 As shown in the specific embodiment 1 or 2, for the heated steel pipe hoisting self-weight flipping pneumatic clamper, the angle formed between the oblique arm and the vertical arm of the clamping arm 1-12 is α, α=135 °. The effect is to keep the left and right vertical arms parallel to each other in the state of clamping the workpiece.

Abstract

The invention discloses a pneumatic clamping machine for lifting and self-weight turning of a steel pipe for heating, and relates to a lifting and clamping device of the steel pipe for heating. The pneumatic clamping machine can be used for the lifting and the clamping of the steel pipe for heating and enables the steel pipe to turn from a horizontal state to a vertical state by dint of self-weight. Two clamping arms are oppositely arranged horizontally; an air distributing valve base is fixed on the outer side surface of the left clamping arm; a cylinder base is fixed on the inner side surface of the left clamping arm; a clamping arm shaft is mounted in first through holes in the upper ends of the two clamping arms and in a first through hole of a clamping arm connecting base; a lifting ring is connected with the clamping arm connecting base; a connecting sleeve base is fixed on the inner side surface of the right clamping arm; a connecting sleeve is fixed on the connecting sleeve base; a piston rod of a cylinder is arranged in the connecting sleeve; the cylinder is fixed on the cylinder base; two clamping head components are fixed at the lower ends of the two clamping arms; an air source guide pipe is communicated with an air reversing valve; the upper and lower ends of a left air guide pipe of the cylinder are communicated with a left cavity of the cylinder and the air reversing valve; and the upper and lower ends of a right air guide pipe of the cylinder are communicated with a right cavity of the cylinder and the air reversing valve. The pneumatic clamping machine is used for lifting, self-weight turning and clamping of the steel pipe for heating.

Description

technical field [0001] The invention relates to a lifting and clamping device for a heated steel pipe, in particular to a pneumatic clamp for lifting a heated steel pipe and turning over by its own weight. Background technique [0002] If one end of the steel pipe is to be necked, it is necessary to heat the necked part of the steel pipe to reduce the necking force or prevent the necked part from wrinkling after shrinking. The steel pipe should be placed horizontally when heating, and the steel pipe should be placed vertically when shrinking after heating. Since the steel pipe has been heated, it cannot be manually turned over and placed by hand. A mechanical device is needed to realize the vertical placement of the steel pipe and to be able to turn it over, thereby assisting in the completion of the closing process of the heated steel pipe. And up to now, still do not have the device that can realize above-mentioned function. Contents of the invention [0003] The objec...
