Description

Technical Field

[0001] This utility model relates to the technical field of H-beam steel production equipment, specifically to an online following transverse laser cutting machine. Background Technology

[0002] In intelligent production lines for corrugated web H-beams, the online accompanying transverse laser cutting machine is a key piece of equipment for cutting and blanking the web steel plates. Existing laser cutting machines in intelligent production lines for corrugated web H-beams have significant limitations; they can only move along the width direction of the web for cutting. However, during transverse cutting, the web steel plate to be processed continuously moves to the next station. This results in a tilted cutting edge, which not only wastes material but also increases the processing and time costs associated with straightening the edge.

[0003] In actual production, in order to ensure product quality and production efficiency, it is urgent to improve the existing laser cutting machine to solve the problem of tilted steel plate cutting edges, and improve cutting accuracy and production efficiency. Utility Model Content

[0004] In view of the problems and shortcomings of the existing technology, this utility model provides an online following horizontal laser cutting machine.

[0005] The technical solution of this utility model is as follows:

[0006] The online accompanying horizontal laser cutting machine includes a frame, a worktable, a positioning roller group, and a laser cutting head. The upper part of the worktable is connected to the laser cutting head through a linear module. The laser cutting head moves along the width direction of the steel plate under the drive of the linear module. Two sets of positioning roller groups are connected to the worktable below the laser cutting head and are symmetrically arranged on the feed side and the discharge side of the laser cutting head.

[0007] It also includes a dynamic adjustment system, through which the worktable is connected to the frame via a sliding pair, and under the precise control of the servo drive unit, it achieves synchronous tracking with the movement speed of the steel plate;

[0008] The dynamic adjustment system includes a servo drive unit, a transmission shaft, and a linear guide unit. The servo drive unit is dynamically coupled to the transmission shaft via a coupling. The transmission shaft and the threaded transmission sleeve in the middle of the worktable form a threaded pair. The linear guide unit is arranged parallel to the transmission shaft and forms a sliding pair with the sliding sleeve on the worktable.

[0009] Each group of positioning rollers includes an elastic pressing roller and a metering reference roller arranged vertically. The elastic pressing roller achieves vertical displacement through a height-adjustable mechanism, and the metering reference roller is axially connected to a rotary encoder.

[0010] The dynamic adjustment system adopts a closed-loop control strategy. The controller of the servo drive unit receives pulse signals from the rotary encoder in real time and dynamically adjusts the moving speed of the worktable through a PID algorithm.

[0011] The elastic pressure roller is coated with polyurethane composite material.

[0012] The metering reference roller is made of metal and its surface is treated with hard anodizing.

[0013] The linear guide unit uses roller-type linear guides, which are arranged symmetrically on both sides of the drive shaft.

[0014] The frame is a frame structure that provides stable support for the entire device.

[0015] The beneficial effects of this utility model are:

[0016] This utility model of an online following transverse laser cutting machine has significant advantages. By dynamically adjusting the system to drive the worktable to move at the same speed as the steel plate, it effectively avoids the problem of tilted cutting edges, reduces material waste, and lowers production costs. At the same time, it improves production efficiency by reducing the increased process and time costs associated with straightening edges.

[0017] The positioning roller assembly accurately measures the moving distance of the steel plate, ensuring accurate cutting length and improving product quality stability. The elastic clamping roller in the positioning roller assembly is coated with polyurethane composite material, increasing friction with the steel plate and providing cushioning to prevent damage to the steel plate surface. The metal material of the metering reference roller ensures its strength and wear resistance, enabling it to withstand the pressure and friction of the steel plate. Furthermore, the vertical spacing between the elastic clamping roller and the metering reference roller is adjustable, adapting to the processing needs of steel plates of different thicknesses and enhancing the equipment's versatility and flexibility. The linear guide unit uses roller-type linear guides, ensuring the stability and straightness of the worktable movement. The frame structure of the machine provides stable and reliable support for the entire equipment, ensuring stability during operation. Attached Figure Description

[0026] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0027] Example

[0028] See Figure 1 The online accompanying transverse laser cutting machine 20 of this utility model is applied in the intelligent production line of corrugated web H-beams.

[0029] See Figure 2 The online accompanying transverse laser cutting machine of this utility model mainly includes a frame 1, a worktable 2, a positioning roller group 3, a laser cutting head 4, and a dynamic adjustment system 5.

[0030] The frame 1 is a frame structure with high strength and stability, providing stable support for the entire equipment and ensuring that the equipment will not shake or deform during operation, thus guaranteeing the accuracy of cutting.

[0031] See Figure 2 and Figure 4 The worktable 2 is connected to the frame 1 via a dynamic adjustment system 5. The servo drive unit 51 in the dynamic adjustment system 5 is dynamically coupled to the drive shaft 52 via a coupling. The drive shaft 52 and the threaded transmission sleeve in the middle of the worktable 2 form a threaded pair. When the servo drive unit 51 is activated, it drives the drive shaft 52 to rotate, causing the worktable 2 to move along the direction of the drive shaft 52 via the threaded pair. The linear guide unit 53 is arranged parallel to the drive shaft 52 and forms a sliding pair with the sliding sleeve on the worktable 2, ensuring the straightness and stability of the worktable 2's movement.

[0032] See Figure 2 and Figure 3The upper part of the worktable 2 is connected to the laser cutting head 4 through a linear module. The linear module includes a guide rail and a slider. The laser cutting head 4 is connected to the slider. The slider moves along the guide rail, thereby causing the laser cutting head 4 to move along the width direction of the steel plate under the drive of the linear module, so as to achieve cutting of the width direction of the steel plate.

[0033] See Figure 2 Two sets of positioning rollers 3 are connected to the worktable 2 below the laser cutting head 4, symmetrically arranged on the feed and discharge sides of the laser cutting head 4. (See also...) Figure 3 Each positioning roller group 3 includes an elastic clamping roller 31 and a metering reference roller 32. The elastic clamping roller 31 is coated with polyurethane composite material and achieves vertical displacement through a height-adjustable mechanism. It can be adjusted according to the thickness of the steel plate, increasing the friction with the steel plate and acting as a buffer to avoid damage to the steel plate surface. The metering reference roller 32 is made of metal with a hard anodized surface, a surface roughness Ra≤0.8μm, and a radial runout tolerance≤0.02mm, ensuring measurement accuracy. The metering reference roller 32 is axially connected to a rotary encoder for measuring the movement distance of the steel plate.

[0034] The dynamic adjustment system 5 adopts a closed-loop control strategy. The controller of the servo drive unit 51 receives pulse signals from the rotary encoder in real time and dynamically adjusts the moving speed of the worktable 2 through the PID algorithm so that the worktable 2 keeps synchronized with the moving speed of the steel plate.

[0035] The specific working process is as follows: During production, the steel plate 10 moves on the production line. The elastic clamping roller 31 and the metering reference roller 32 of the positioning roller group 3 clamp the steel plate 10. The metering reference roller 32 rotates as the steel plate 10 moves. The rotary encoder detects the rotation of the metering reference roller 32 and transmits pulse signals to the controller of the servo drive unit 51. Based on the received signals, the controller calculates the speed that the worktable 2 needs to be adjusted using a PID algorithm, and then controls the servo drive unit 51 to adjust the rotation speed of the transmission shaft 52, thereby adjusting the moving speed of the worktable 2 to synchronize it with the moving speed of the steel plate 10. At the same time, the laser cutting head 4 moves along the width direction of the steel plate under the drive of the linear module, performing transverse cutting on the steel plate 10, ensuring the accuracy and quality of the cutting.

[0036] In summary, this utility model of an online following transverse laser cutting machine achieves high-precision cutting of steel plates through reasonable structural design and advanced control strategies, and has significant economic benefits and practical value.

Within the scope of knowledge possessed by those skilled in the art, all variations, equivalent substitutions, and improvements made without departing from the concept of the present invention should be included within the protection scope of the present invention.
