Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe production equipment, and particularly relates to a support frame for a rectangular steel pipe needle-punch marking machine. Background Art

[0002] Most steel pipes require marking during production, and some, in particular, require needle-punch marking. This is because steel pipes require passivation during production and subsequent galvanizing. If printed marking is used, the marking will obviously be affected during passivation and galvanizing, resulting in incomplete display or no display at all. Some steel pipe markings require a longer retention time, and printed marking cannot meet this requirement. Currently, there is no online needle-punch marking device specifically for steel pipe production lines on the market. In order to perform needle-punch marking on steel pipes, offline marking is often used. However, offline marking undoubtedly increases equipment investment, reduces production line efficiency, and increases production costs. In response to market demand and the shortcomings of previous technologies, our company independently developed and designed a rectangular steel pipe needle-punch marking production line, which effectively solves the problem of online steel pipe marking and meets market demand. A support frame for a rectangular steel pipe needle-punch marking machine is an important component of this production line. Summary of the Invention

The rotating seat is arranged at the top of the column, the cantilever is arranged on the rotating seat, the roller group is arranged at the outer end of the cantilever, and the spring balancer is connected to the roller group. The roller group consists of a guide rail, a roller, a connecting plate, a sleeve, and a connecting ring. The guide rail is fixed on the cantilever, the roller is rotatably arranged on the guide rail, the connecting plate is arranged on the roller, the sleeve is arranged on the connecting plate, and the connecting ring is arranged on the sleeve.

[0006] Moreover, the rotating seat is composed of a base plate, a central axis, a rotating sleeve, an upper bearing, a lower bearing, and a locking nut. The base plate is fixed to the top of the column, the central axis is concentrically fixed to the base plate, the upper bearing is on the top, the lower bearing is on the bottom and is concentrically arranged on the central axis with the rotating sleeve, and the locking nut is locked to the top of the central axis.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely illustrative and non-restrictive, and should not be used to limit the scope of protection of the present invention.

[0019] A rectangular steel tube needle marking machine support frame consists of a column 6, a cantilever 3, a rotating seat 5, a roller group 1, and a spring balancer 2. The rotating seat is arranged at the top of the column, the cantilever is arranged on the rotating seat, the roller group is arranged at the outer end of the cantilever, and the spring balancer is connected to the roller group.

[0020] The roller assembly consists of a guide rail 9, roller 7, connecting plate 8, sleeve 10, and connecting ring 11. The guide rail is fixed to the cantilever, the roller is rotatably mounted on the guide rail, the connecting plate is mounted on the roller, the sleeve is mounted on the connecting plate, and the connecting ring is mounted on the sleeve. When the marking machine is pulled, this structure allows the marking machine to move horizontally, thereby moving the suspended marking machine to the desired horizontal position.

[0021] The swivel base consists of a base plate 17, a central shaft 14, a rotating sleeve 15, an upper bearing 12, a lower bearing 16, and a locking nut 13. The base plate is fixed to the top of the column, and the central shaft is concentrically fixed to the base plate. The upper bearing is located above, and the lower bearing is located below, coaxially with the rotating sleeve and set on the central shaft. The locking nut is locked at the top of the central shaft. When the marking machine is pulled, this structure allows the cantilever to rotate 360 degrees around the column, thereby moving the suspended marking machine horizontally to the desired position.

[0022] The cantilever is an I-beam type, on which a reinforcing beam 4 is arranged.

[0023] The spring balancer is a self-locking spring balancer that can keep the marking machine in a weightless state. When the marking machine is pulled, it can move up and down, so that the marking machine suspended on it can be moved to the required height.

[0024] The marking machine is a Chuangjing brand portable steel stamping and engraving marking machine.

[0025] The working principle of this utility model:
