でキャノンと呼称される。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an entrance guide tube (cannon-shaped) for introducing material between the rolls in a pipe manufacturing machine such as a vertical punching machine or a drawing machine in which rolls are arranged above and below a bus line. That's why it's called Canon.

定するクランプ装置を設けたことを特徴とする。The horizontal type has two rolls placed horizontally and in parallel at a constant angle of inclination at positions equidistant to the left and right from the bus center, and the cannon is placed at the bus center. Therefore, when replacing the cannon, either press the cannon from above and remove the holder vertically that secures the cannon, or if the holder has a pin joint on the side, use this pin as the center. The holder was rotated to remove it from the top of the cannon, and then the cannon was lifted vertically with a crane and replaced. Replacing this cannon is done every time the rolling size is changed, but since it is done in a place with poor footing and leaning on the input, the work takes half a day to several days. However, if the mounting part is made simpler to improve workability, it will easily come loose due to vibration during operation. In particular, in the case of a vertical drilling machine or drawing machine, the cannon is installed directly below the upper roll drive shaft, so the cannon cannot be replaced using conventional methods and structures. The present invention aims to improve the mounting structure of a cannon for a vertical pipe making machine so that it can be easily replaced and can be securely fixed without loosening easily due to vibration during operation. The structure of the present invention that achieves the object is that, in a vertical pipe making machine in which rolls are arranged above and below a bus line, the entrance guide tube, which is located above the bus center and introduces the material between the rolls, is arranged on a vertical axis remote from the bus center. A hydraulic cylinder is provided which is attached to the frame so as to be able to rotate freely around the frame and which rotates the entry guide cylinder, and a horizontal axis which runs along the bus line is provided to the frame and which is press-fitted into the groove. A wing-like engagement member for fixing the input guide tube to the frame is provided at one end of the input guide tube, and the front guide tube is pressed in the axial direction, the vertical direction perpendicular to the axis, and the left and right directions. The present invention is characterized in that a clamp device is provided for fixing the other end of the entry-side guide cylinder to the frame.

By the operation of , it swings and turns around pin 7, which is a vertical axis. By this rotation, the cannon 1 is taken out from the bus center around the pin 7, passing through the upper roll drive shaft 104, and out of the bus line perpendicular to the operating position. Alternatively, it is installed from outside the bus line to the bus center. Note that the hydraulic cylinder 4 and the swing arm 2 are connected by a pin 8. It is also possible to use high pressure air as the working fluid. A wing-like engagement member 12 is attached to one end of the cannon 1.

Both the wing-like engagement member 12 and the groove 13 are formed into a wedge V shape to provide strong fixing and an alignment function. Note that the groove 13 formed in the protrusion 3 portion on the frame 101 also serves as a stopper for the cannon 1, so one side is closed and the groove 13 is provided so as to become slightly narrower toward the closed side. Further, a square washer 14 is formed at the other end of the cannon 1 to protrude laterally.

如く行なわれる。This washer 14 is attached to the frame 101 as shown in FIG.
A wedge-shaped stopper 10'a parallel to the bus center provided on a columnar frame 10' which is a part of the frame 10' is placed on the frame 10' to position the other end of the cannon 1. Also serves as a clamped part. Clamp devices 15a, 15 for tightening the washer 14
b consists of a bell-crank-shaped pawl 6 attached to the frame 10 through a bracket 16, a hydraulic cylinder 5 for actuating this, and the frame 10. the object 15a that is pressed against the frame 101″ and the stopper 1 of the frame
There are two types: 15b, which is pressed toward the top of the frame 10a, and a bellcrank-shaped pawl 6, which is operated by a hydraulic cylinder 5 installed upright at the bottom of the frame 10a.
This is done by raising and lowering one side of the The contact surface of one or both of the claw 6 and the washer 14 of this clamping device is formed into an inclined surface, and when clamping, the cannon 1 is moved in the axial direction, the frame 10 direction, and the stopper 10.
``It is designed so that a pressing force is applied in three directions in the a direction.This allows for positioning and strong fixation.Since it is configured in this way, the cannon replacement work is performed as follows.

み合うようように調整しながら降ろす。Since the claw 6 consisting of a bell crank rotates around the pin 9, the washer 14 of the cannon 1 is released. Next, the rod of the hydraulic cylinder 4 of the swing arm 2 is retracted. The swing arm 2 swings about 900 degrees forward about the pin 7 and is taken out of the bus line. At this time, the hydraulic cylinder 4
A boost pressure is first applied to the V-shaped groove 13 so that the wing-like engagement member 12, which is forcefully press-fitted into the V-shaped groove 13, can be pulled out with a strong force. Once the turning arm 2 starts turning, there is no need to pull it with a strong force. After being taken out of the bus line, it is lifted up by a crane (not shown). By lifting, the hook portion 2a and the key-shaped arm 11 are uncoupled, and the cannon 1 is removed from the rotating arm 2. 2
A cannon 1 of a desired size for mounting the cannon is transported to a rotating arm 2 part by a crane, and then lowered while adjusting so that the arm 11 and the hook part 2a are well engaged.

たやすく弛まないように確実に強固に固定できる。The cannon 1 attached to the swing arm 2 is turned and moved to the bus center by the operation of the hydraulic cylinder 4. Next, the hydraulic cylinders 5 of the clamp devices 15a and 15b are operated to tighten the washer 14 at the other end of the cannon 1, thereby fixing and positioning the cannon 1. The two claws 6 move the cannon 1 in three directions: axially (toward the groove 13), perpendicular to the axis (toward the stopper 10'a), and downwardly (toward the top of the frame 10'). Since the cannon 1 is pressed, it is positioned on the bus center and at the same time securely held on the frame.In particular, the hydraulic cylinder 5 of the clamping device 15a that presses the cannon 1 in the axial direction is subjected to the highest pressure at the end of the stroke. Therefore, under the aligned state, the wing-like engaging member 12 is in the groove 13 of the frame 101.
is strongly press-fitted into the According to the present invention, a wing-shaped engaging member is provided at one end of the cannon so as to be press-fitted into a groove in the frame, while the other end of the cannon is pressed against the cannon in three axes directions perpendicular to each other. Since a clamping device is provided for fixing the cannon to the cannon, the interaction between these makes it possible to easily remove the cannon and to ensure that the cannon is firmly fixed so that it will not easily loosen due to vibrations during operation.

る。Moreover, by rotating the cannon around the pin and taking it out of the bus line from the bus center, replacement can be easily and quickly performed. Further, since the wing-shaped engaging member and the clamp device each have a certain reference plane and are fixed by being press-fitted or pressed along this plane, they are automatically aligned at the same time as the cannon is fixed. It can shorten work time such as alignment.
