A profiled steel straightening machine inlet guide device

Abstract

This utility model patent belongs to the field of equipment technology in the steel industry, and is an inlet guide device for a steel straightening machine invented to achieve stable entry of steel sections into the straightening machine. The main components include a base, a screw jack, a fixed seat, a vertical roller assembly, side guide plates, and a guide plate. The screw jack is mounted on the base via the fixed seat and connected to the vertical roller assembly. The side guide plate adopts a thickened stepped recessed design and is fixed to the roller base via positioning pins and sleeve seats. The vertical roller assembly is fixed to the base via the guide plate. This reduces the installation height of the load-bearing components, the vertical roller assembly and the side guide plate, down to the base, thus reducing the height-to-width ratio of the entire guide device and decreasing the overturning moment when the steel section impacts the guide device, thereby preventing impact damage. The vertical roller assembly can be adjusted in position under the action of the screw jack, making it suitable for straightening and introducing steel sections of different specifications. Under the locking of the screw jack, a stable structure is formed, enabling the initial straightening of bent steel sections.

Description

Technical Field

[0001] This utility model relates to an inlet guide device for a steel profile straightening machine in the steel industry. Background Technology

[0002] In the production of structural steel, qualified products must meet the straightness requirements and need to be straightened one by one on a straightening machine. Currently, the inlet guide device of the straightening machine is fixed at the inlet of the straightening machine. Due to the large height-to-width ratio of the guide device, the overturning moment of the guide device is relatively large. When the bent structural steel advances through the center of the inlet guide, it will irregularly hit the inlet side guide plate, causing the guide device to overturn and be damaged, which seriously affects the production efficiency. Summary of the Invention

[0003] The technical problem solved by this utility model is that when the inlet guide of the existing steel profile straightening machine passes through the bent steel profile, the steel profile collides with the side guide plate, causing the side guide plate to overturn and be damaged, the surface of the steel profile to be scratched, and the production efficiency to be low.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: An inlet guide device for a steel profile straightening machine is invented and installed between the roller conveyors in front of the straightening machine. The main components include a base, a screw jack, a fixed seat, vertical roller assemblies, pins, positioning plates, side guide plates, guide plates, guide plate bases, positioning pins, and sleeve seats. The vertical roller assemblies are respectively arranged on the left and right sides of the straightening machine inlet. The spacing between the two vertical roller assemblies is set according to the width of the steel profile to be straightened. The vertical roller assemblies are connected to the screw jacks. By adjusting the screw jacks, the position of the vertical rollers can be adjusted and locked. When the steel profile enters the straightening machine, it first passes through the side guide plates arranged in a figure-eight pattern on the left and right sides of the straightening machine, and then is rolled into the straightening machine inlet by the vertical roller assemblies on both sides.

[0005] The base has welding mounting seats on both sides for mounting and fixing the screw jack.

[0006] A guide plate base is welded to the middle of the base. The upper surface of the guide plate base is machined with grooves and threaded holes. Four guide plates are fixed to the guide plate base of the base by bolts.

[0007] The vertical roller assembly includes a guide seat, a shaft, a vertical roller, a bearing, a bushing, and a vertical roller cover. The shaft is mounted on the guide seat, the bushing is mounted on the shaft, the bearing is mounted on the bushing, the vertical roller is mounted on the bearing, and the vertical roller cover is mounted on the vertical roller.

[0008] The guide seat has guide grooves machined on both sides, and the guide seat can be installed on the guide plate through the guide grooves on both sides. The front end of the guide seat has a shaft hole for installing the shaft of the vertical roller assembly, and the rear end has a pin hole for installing the pin. The screw jack can be connected to the guide seat through the pin, and the pin is positioned by the positioning plate.

[0009] The bushing is used to install and position the bearing.

[0010] The vertical roller is mounted on the shaft via bearings and bushings.

[0011] The shaft is installed in the shaft hole, the bushing is installed on the shaft, the lower end of the shaft is positioned by the shaft end retaining ring, and the upper end of the shaft is positioned by the shaft shoulder.

[0012] The bushing is installed inside the guide seat, and a step is provided in the middle of the bushing for installing the positioning bearing. The vertical roller is installed on the outside of the bearing, and the vertical roller cover is installed on the upper and lower end faces.

[0013] The vertical roller cover is bolted to both ends of the vertical roller and is used to position the bearing and the vertical roller.

[0014] The side guide plate has a round hole at the tail end, which is connected to a shaft. The guide plate has a strip hole in the middle, which is connected to the roller base via a pin. When the vertical roller is adjusted, the side guide plate can slide through the strip hole. The side guide plate adopts a thickened stepped recessed design, with one end fixed to the guide seat via a shaft and the other end fixed to the roller base via a pin, which increases the stability of the impact.

[0015] Compared with related technologies, this utility model has the following advantages: The side guide plate of this guiding device is directly fixed to the roller conveyor base, and the vertical roller is fixed to the base through the guide seat. That is, the installation height of the load-bearing vertical roller and the side guide plate is reduced to the base, which reduces the height-to-width ratio of the entire guiding device and reduces the overturning moment of the steel section impacting the guiding device, thereby avoiding impact damage to the guiding device. The adjustable vertical roller can be used for straightening and guiding steel sections of different specifications. Under the locking action of the screw jack, the vertical roller forms a stable structure, which can realize the initial straightening of bent steel sections. Attached Figure Description

[0039] Structural Description: An inlet guide device for a steel profile straightening machine, installed between the roller conveyors in front of the straightening machine. Main components include a base 1, screw jacks 2, guide plates 3, vertical roller assembly 4, side guide plates 7, fixed seats 8, and guide plate base 9. Two fixed seats 8 are welded to both sides of the base 1, and two screw jacks 2 are symmetrically mounted on the fixed seats 8 by bolts. The telescopic screws of the screw jacks 2 are connected to the guide seats 10 of the vertical roller assembly 4 via pins 5. The vertical roller assembly 4 includes the guide seats 10, shafts 12, vertical rollers 13, bearings 14, bushings 15, and vertical roller covers 11. The vertical rollers 13 are mounted on the guide seats via bearings 14, bushings 15, and shafts 12. 10; the guide seat 10 is installed on the guide plate 3 through the guide grooves on both sides, and can slide back and forth linearly along the guide plate 3; the guide plate 3 is fixed to the guide plate base 9 by bolts; the guide plate base 9 is welded to the middle position of the base 1; the shaft 12 is installed in the shaft hole at the front end of the guide seat 10, the pin 5 is positioned by the positioning plate 5, and the vertical roller cover 11 is fixed to both ends of the vertical roller 12 by bolts; one end of the side guide plate 7 is connected to the shaft 12, and the other end is connected to the roller table base through the positioning pin 16 and the sleeve seat 17, and the sleeve seat 17 is welded to the roller table base.

[0040] Workflow: During operation, the screw jack 2 first adjusts the positions of the vertical roller assembly 4 and the side guide plate 7 according to the specifications of the steel section. When the roller conveyor transports the steel section to the inlet guide device of the straightener, the head of the steel section is gradually guided into the vertical roller 13 of the guide device through the side guide plate 7. The roller surface of the vertical roller 13 rolls into contact with the side of the steel section and rolls into the straightener under the transmission of the roller conveyor. Utilizing the self-locking characteristic of the screw jack 2, for steel sections with large curvature, the two vertical rollers 13 can be used as auxiliary straightening equipment to withstand a certain lateral force and perform preliminary straightening of the steel section, avoiding the steel section from being unable to enter the straightener due to excessive curvature and thus being taken off the production line.
