Embodiment 1

[0041]A special-shaped pipe forming process for a log splitter oil cylinder, specifically as follows:

[0042] Uncoiling, install the steel strip coil on the uncoiler, and the uncoiler drives the steel strip coil to rotate and cooperate with the blade to disassemble the steel coil. The center of the steel strip coil is located on the center line of the unit, and a micro-braking device is installed on the uncoiler to prevent the steel strip from being rolled back into an elastic loose coil during an emergency stop.

[0043] Leveling, straight pinch leveling machine middle pressure roller and shovel cooperate with uncoiler to disassemble the steel strip head, and send the steel strip to straight pinch leveler. The shovel cooperates with the straight head pressure roller to straighten the head of the steel strip, and then sends the steel strip to the pinch roller. The pinch roller presses down to clamp the steel strip, and turns the main motor to send the steel strip to the pinch...

Embodiment 2

[0062] The difference between this embodiment and Embodiment 1 is that the elastic blocking reset device 5 includes a cross bar perpendicular to the piston rod of the two-way hydraulic cylinder and fixedly connected to the support beam, and a stopper 7 sleeved on the cross bar. Both sides of the block are respectively provided with springs 11 connected to the support beam. The two springs are arranged in a figure-eight shape, and the connection point between the spring and the block is higher than the axis of the cross bar. The lower edges on both sides are provided with circular arc chamfers, the distance from the axis of the cross bar to the front and rear sides of the boss lower part of the block is less than the distance to the upper surface of the support beam, and the front and rear edges of the lower end of the electromagnet are also provided with circular arc chamfers.

[0063] When the electromagnet does not touch the block, the springs on both sides keep it in a balan...

Abstract

The invention relates to a special pipe forming technology for a log splitter oil cylinder. The technology comprises the steps that 1, uncoiling is carried out, and particularly a steel belt coil is uncoiled; 2, leveling is carried out, and particularly the uncoiled steel belt is leveled and conveyed to a next station; 3, end flattening and butt welding are carried out, particularly, the head andthe tail of the leveled steel belt are sheared and flattened, and the tail of the sheared and end-flattened steel belt and the head of a next sheared and end-flattened steel belt are welded together;4, prestoring is carried out, and particularly the but-connected steel belts are conveyed into a loop storage bin; 5, forming is carried out, particularly, the steel belts in the loop storage bin areconveyed into a forming machine, and the steel belts are gradually bent in sequence to form pipe blanks to be welded; 6, high-frequency welding is carried out, and particularly high-frequency weldingis carried out after the two butt-connected ends of the pipe blanks are extruded to the certain opening angle; 7, water cooling is carried out, the steel pipes welded at a high frequency are cooled toroom temperature in a spraying mode; 8, special gradient sizing is carried out, and particularly the water-cooled steel pipes are sized through a sizing unit; and 9, contour machining is carried out,and particularly the sized steel pips are cut to specific lengths.

Description

technical field [0001] The invention relates to the technical field of steel pipe forming, in particular to a process for forming a special-shaped pipe for an oil cylinder of a wood splitter and a mold replacement device. Background technique [0002] Straight seam steel pipe is mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, etc. It can be used for liquid transportation, such as water supply and drainage, and can also be used for gas transportation, such as gas, steam, liquefied petroleum It can also be used as a structure, as a piling pipe, as a bridge, and as a pipe for docks, roads, and building structures. In recent years, straight seam welded pipes have also been used in log splitter oil cylinders, but the production process of straight seam welded special-shaped steel pipes for log splitter oil cylinders is relatively complicated, resulting in high production cost...
