Description
Technical Field
The invention relates to a steel strip manufacturing process, in particular to a steel strip online pressing and trimming device and method.
Background
The on-line trimming method for the pressing non-removed material on the edge of the steel strip is used for trimming the edge of a cold-bending sharp-angled steel pipe product for a tower crane.
Due to the particularity of the welding mode of the cold-bent sharp-angled steel pipe for the tower crane, namely as shown in figure 1, two welding edges are jointed in a welding area. If the materials of the two welding edges are not removed, overlapping and overlapping as shown in fig. 1 can be caused during welding, namely, the corresponding parts of the welding edges are in non-uniform contact in sequence, and the welding quality is influenced. After trimming, namely as shown in fig. 2, the two welding edges are simultaneously and uniformly jointed and welded in the welding area, and the welding quality is good.
1. The cold-bent sharp-angled steel pipe for the tower crane needs to be trimmed and then welded on line due to the welding particularity (see figures 1-2). The traditional on-line trimming method is a trimming method for removing materials, and the quality of the planed and trimmed edges (trimming parameters and trimming surface finish degree) is difficult to ensure due to the fact that the quality of edge plates of planed materials is unstable, planing blades are easy to damage, the stability of planing equipment is not strong, and the operation level of planing operators is poor, and the welding quality of cold-bent sharp-angled steel pipes for tower cranes is directly influenced. Meanwhile, the normal continuous production rhythm of the cold-bent sharp-angled steel pipe for the tower crane is directly influenced when the blades are damaged and replaced and the planing equipment fails. In addition, the material removal method results in material waste, and statistically, the removed material affects the yield by about 0.5%, resulting in more cost consumption.
2. The steel strip edge pressing non-removal material online trimming method adopts a mature roller type die to press and deform the edge of the steel strip, and can press the edge of the steel strip through the roller type die with different hole patterns for many times to form a required angle, a required trimming amount and a high and smooth surface degree, so that the welding requirement is met.
In summary, the conventional methods for removing material have the following disadvantages:
1) The traditional on-line trimming method for removing materials has the problem that the planing quality is difficult to ensure due to the fact that the plate shape of the edge of a steel strip is unstable, a planing blade is easy to damage, the stability of planing equipment is insufficient, the operation level of planing operators is poor and the like.
2) In the traditional on-line trimming method for removing materials, when the quality is poor in the using process, the machine needs to be stopped for adjustment, so that the production rhythm and efficiency are greatly influenced.
3) The traditional on-line material removing and trimming method causes material loss, and the production cost is high.

Deformation process: clamping and conveying the steel strip to be trimmed to the tightly connected five-frame pressing and trimming vertical roller group → the first deformed frame (the edge pressing angle is 15 degrees, and the trimming height is H) 1 ) → second deformation frame (side pressing angle 30 DEG, trimming height H) 2 ) → third deformation frame (edge pressing angle 40 °, trimming height H) 3 ) → fourth deformation frame (side pressing angle 47 deg., trimming height H) 4 ) → finishing frame pass (edge pressing angle 45 DEG, trimming height H, surface roughness
) → the edge-trimming strip is pinch fed to the mill.
2) The assembly principle of the online pressing and trimming device and the functions of all parts of the online pressing and trimming device are as follows:
the pressing trimming mechanism consists of a front pinch roll, five-frame vertical roll groups with close intervals and a rear pinch roll; the front pinch roll and the rear pinch roll are clamped by an upper roll and a lower roll and are actively transmitted; the five-frame vertical roll seat has the same structure, each frame specifically comprises a pressing vertical roll, a vertical roll shaft lifting mechanism, a vertical roll locking nut, a vertical roll shaft seat, a vertical roll transverse adjustment advancing and retreating mechanism and a vertical roll seat, the total number of the vertical roll seats is 5, and each vertical roll is provided with a hole pattern for steel strips with different thicknesses; the 1,2,3 and 4 th stands are initial deformation stands (the 4 th stands are excessive edge deformation stands), and the 5 th stands are finishing stands.
(1) The lifting mechanism: the lifting mechanism is a mechanism for adjusting the vertical roll to lift up and down, the bottom of the vertical roll shaft is connected with the vertical roll shaft seat in a spiral connection mode, and when the lifting mechanism is used, the top of the vertical roll shaft is rotated to realize the vertical lift of the vertical roll shaft so as to ensure that the required vertical roll hole pattern is at the correct position in the height direction;
(2) pressing the vertical roller: depending on the angle in the hole pattern and the H size, the edge part of the steel strip reaches the required angle and trimming value through transverse tightening after entering; the lower part of the hole pattern is provided with a 1-degree release angle, so that the bottom scratch caused after a steel belt enters the vertical roller is avoided; corresponding hole patterns suitable for different wall thicknesses are arranged on the upper surface.
(3) Locking the nut: the pressing vertical roller is locked to ensure that the vertical roller does not jump up and down during working to influence trimming precision;
(4) an advancing and retreating mechanism: the advancing and retreating mechanism is connected with the two vertical roll shaft seats in a spiral mode through a transverse adjusting screw rod; when the horizontal adjustment is needed, the distance between the two vertical roll shaft seats is changed by adjusting the screw rod on the operation side, so that the aim of horizontal tightening or loosening is fulfilled.

installing and adjusting a front pinch roll, enabling a steel strip to penetrate into and pinch to a five-frame vertical roll group → adjusting a lifting mechanism of each frame vertical roll shaft, selecting a vertical roll hole type matched with the thickness on a vertical roll, ensuring that the vertical roll can completely bite into the steel strip → adjusting a driving and reversing mechanism connected with a shaft seat of the vertical roll to a proper distance, ensuring that the edge of the steel strip can be completely pressed and pressed → adjusting a rear pinch roll, ensuring that the pressed steel strip can be transmitted to a rolling mill → the front pinch roll and the rear pinch roll start to press the edge of the steel strip → continuously transmit the steel strip while detecting edge parameters of the deformed steel strip and observing the edge deformation condition, timely adjusting the height and the transverse distance of the pressed vertical roll according to a measurement result, ensuring that the edge pressing parameters are qualified → adjusting the frame parameters are qualified, and then normally transmitting the steel strip to the rolling mill to carry out cold bending forming and welding production.
When the steel strip to be trimmed enters the 1 st, 2 nd, 3 rd and 4 th primary deformation frame times, the pressing vertical roller is lifted and tightened according to the thickness of the steel strip and the plate type condition of the edge, and the pressing upper roller is transversely and downwards pressed and adjusted, so that the edge of the steel strip can continuously and stably meet the requirement of the deformation parameter of each frame time. And finely adjusting the pressing vertical roller during finishing, transversely adjusting and pressing down the pressing vertical roller to press the upper roller, so that the parameters of the edge of the steel strip meet the final welding quality requirement.
