Embodiment 1

[0041] A process for forming longitudinally welded special-shaped steel pipes for automobile anti-collision beams is as follows:

[0042] Uncoiling, install the steel coil on the decoiler, and the decoiler drives the steel coil to rotate and cooperate with the shovel to disassemble the steel coil. The center of the steel strip coil is located on the center line of the unit, and a micro-brake device is set on the uncoiler to prevent the steel strip coil from returning to spring loose coil during emergency stop.

[0043] Leveling, straight-head pinch-feed leveling machine, the pressure roller and shovel cooperate with the decoiler to disassemble the steel strip head, and send the steel strip to the straight-head pinch leveler. The shovel is matched with the straight-headed pressure roller to straighten the head of the steel strip and then the steel strip is sent to the pinch roller, the pinch roller is pressed down to clamp the steel strip, and the main motor is rotated to send the s...

Embodiment 2

[0062] The difference between this embodiment and the first embodiment is that the elastic blocking reset device 5 includes a cross bar perpendicular to the piston rod of the bidirectional hydraulic cylinder and fixed to the support beam, and a stopper 7 sleeved on the cross bar. Both sides of the stop block are respectively provided with springs 11 connected to the support beam, the two springs are arranged in a figure eight shape, the connection point between the spring and the stop block is higher than the axis of the crossbar, the stop block is T-shaped, and the upper part of the stop block is convex The lower edges on both sides are provided with arc chamfers, the distance from the axis of the cross bar to the front and rear sides of the lower boss of the stopper 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 arc chamfers.

[0063] When the electromagnet does not tou...

Abstract

The invention relates to a straight seam welding special-shaped steel pipe forming process for an automobile anti-collision beam. The straight seam welding special-shaped steel pipe forming process for the automobile anti-collision beam comprises the following steps of: (1) uncoiling, unrolling a steel strip coil; (2) flattening, flattening the unrolled steel strip and conveying the flattened steel strip to the next station; (3) flat cutting and butt welding, flat cutting a head portion and a tail portion of the flattened steel strip respectively, and butt welding a tail of the steel strip material after the flat cutting with a head of the next steel strip material after the flat cutting; (4) pre-storing, feeding the butt welded steel strip into a movable sleeve storage bin; (5) forming, conveying the steel strip in the movable sleeve storage bin to a forming machine, and gradually bending into a tube blank to be welded according to a certain sequence; (6) high-frequency welding, pressing the opposite ends of the tube blank to form a certain opening angle, and then to perform high-frequency welding; (7) Water cooling, cooling the high-frequency welded steel tube to room temperatureby spraying; (8) special-shaped gradient sizing, sizing the water-cooled steel tube by a sizing ; (9) profile machining, cutting the sized steel tube into specific lengths.

Description

Technical field [0001] The invention relates to the technical field of steel pipe forming, in particular to a forming process and a mold replacement device for a straight seam welded special-shaped steel pipe for an automobile anti-collision beam. Background technique [0002] Straight seam steel pipes are mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, etc., can be used for liquid transportation, such as water supply, drainage, and gas transportation, such as gas, steam, and liquefied petroleum. Gas can also be used as a structure, as a piling pipe, as a bridge, or as a pipe for docks, roads, and building structures. In recent years, the longitudinally welded pipes have also been widely used in the automotive field and the furniture and home furnishing fields. Among them, the longitudinally welded special-shaped steel pipes are widely used in automobile beams, automobile dec...
