Technical Field
[0001] The invention relates to a round steel straightening machine and method capable of quickly changing product types, belonging to the technical field of round steel galvanizing. Background Art
[0002] Currently, in the round steel galvanizing industry, the mainstream products are φ8-12mm and φ12-16mm galvanized round steel. To produce these two series of φ8-12mm and φ12-16mm galvanized round steel, galvanizing plants typically deploy two production lines, equipped with corresponding straightening machines, or by replacing straightening machine parts to accommodate different production specifications. Existing straightening machines generally consist of horizontal and vertical straightening wheel sets to straighten a single specification of galvanized round steel. However, for specifications with lower market demand, equipping them with corresponding straightening machines results in idle equipment capacity. Replacing straightening machine parts, however, can lead to lengthy production line downtime due to the time-consuming adjustment and matching process, thus impacting overall production capacity. Summary of the Invention
[0003] The purpose of the present invention is to provide a round steel straightening machine and method that can quickly change the product type. By quickly switching production specifications, the time for replacing accessories and debugging is reduced, the overall production efficiency is improved, the production cost is reduced, and the flexibility of the production line is enhanced. The straightening machine can be compatible with more production specifications, meet the production needs of products of different specifications, and solve the above-mentioned technical problems existing in the background technology.

[0005] A positioning bolt is provided between the bottom of the rack and the frame. After determining the corresponding vertical straightening channel, the bottom of the rack and the frame are positioned and fixed. When the vertical straightening channel needs to be replaced, the positioning bolt is loosened for adjustment.
[0006] A slideway is provided between the bottom of the rack and the frame. The slideway is fixed on the frame, and the rack slides transversely on the slideway.
[0007] The translation adjustment mechanism consists of two identical translation devices, each comprising a lead screw (1), a bevel gear set, and a mounting base. The bevel gear set is mounted on the frame, with lead screw nuts at both the input and output ends. The front end of lead screw (1) is mounted on the frame via the mounting base, and the rear end of lead screw (1) mates with the lead screw nut at the output end of the bevel gear set. The lead screw nuts at the input ends of the two translation devices mate with the same lead screw (2), and a handwheel is provided at the end of lead screw (2) to ensure synchronous drive of the two translation devices. Turning the handwheel drives lead screw (2), causing the bevel gear set to shift the direction of lead screw (2) by 90°. The output rotational force drives lead screw (1) forward, which in turn propels the frame laterally via the mounting base.
[0008] The rear end of the frame is provided with a passivation groove, and the straightened round steel enters the cutting-to-length mechanism or the coiling machine through the passivation groove.
[0009] The frame is provided with a pulley transmission mechanism to provide power for the horizontal straightening wheel group and the vertical straightening wheel group.
[0010] A round steel straightening method capable of quickly changing product types, using the above-mentioned round steel straightening machine, comprises the following steps: The vertical straightening wheel group is provided with two or more different vertical straightening channels; the straightening box is arranged on the frame, and the bottom of the frame slides and translates on the frame through a translation adjustment mechanism. According to the different types of products, the frame moves to the position of the corresponding vertical straightening channel to realize switching between different vertical straightening channels, straighten galvanized round steels of different specifications, and complete the conversion of product types.
[0011] When switching between product types, the operator simply controls the translation adjustment mechanism to move the frame to the appropriate position and secure the positioning bolts. This allows for quick adjustment of the straightener without having to replace any accessories. This significantly reduces adjustment time and downtime, improving the production line's productivity and flexibility. The straightener is compatible with a wider range of production specifications, reducing the problem of idle equipment capacity caused by specifications with low market demand.
[0012] The horizontal straightening wheel group of the present invention is responsible for the initial straightening of round steel, ensuring that the round steel has good straightness before entering the vertical straightening wheel group; the vertical straightening wheel group accurately straightens the galvanized round steel of corresponding specifications according to the selected vertical straightening channel.
[0013] The present invention not only improves the flexibility of the production line, but also significantly reduces production costs and downtime, and realizes rapid switching of product varieties without the need for complicated parts replacement and debugging processes.
[0014] The beneficial effects of the present invention are: 1. Improved production efficiency: By quickly switching production specifications, the time for replacing parts and debugging is reduced, allowing the production line to adapt to changes in market demand more quickly and improving overall production efficiency.
[0015] 2. Reduced production costs: This avoids the problem of idle equipment capacity caused by configuring separate production lines, and also reduces the additional costs caused by replacing parts and long-term production stoppages.
[0016] 3. Enhanced flexibility of the production line: The new straightening machine is compatible with more production specifications, allowing the production line to more flexibly respond to the production needs of products of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS
