High-efficiency flattening mechanism for aluminum plate leveling machine

Abstract

This utility model discloses a high-efficiency flattening mechanism for an aluminum plate leveling machine, relating to the field of aluminum plate leveling machines. It addresses the problem that existing leveling machines rely solely on a flattening mechanism to flatten the surface of the aluminum plate, failing to completely eliminate internal stress, and the flattened aluminum plate may still spring back under stress, affecting the final flatness. A first quartz heating tube is fixedly connected between the two supporting side plates and at the midpoint between adjacent supporting rollers. C-shaped support frames are fixedly connected to both sides of the midpoint at the upper end of the two supporting side plates. Multiple lower pressure rollers are rotatably connected at equal intervals at the lower ends of the two lifting support plates. A second quartz heating tube is fixedly connected between the two lifting support plates and at the midpoint between adjacent lower pressure rollers. By simultaneously heating the aluminum plate with the first and second quartz heating tubes, the aluminum plate reaches its stress-relieving temperature during the flattening process, effectively eliminating residual stress within the aluminum plate.

Description

Technical Field

[0001] This utility model relates to the field of aluminum plate leveling machines, specifically to a high-efficiency flattening mechanism for aluminum plate leveling machines. Background Technology

[0002] An aluminum sheet leveling machine is a specialized piece of equipment used for straightening and cutting aluminum coils. It primarily unrolls, leveles, and cuts coiled aluminum sheets into flat sheets of the required size. Its core function is to eliminate internal stress, wavy edges, warping, and other defects generated during the coiling process using a multi-roller leveling system, ensuring the flatness of the sheet material. It is suitable for industries such as building decoration, automobile manufacturing, and electronics.

[0003] For example, authorization announcement number CN217528688U discloses an aluminum strip leveling machine for aluminum strip casting and rolling, including a housing. Both ends of the housing are equipped with fixed frames. A limiting mechanism is rotatably connected inside the fixed frame. The limiting mechanism includes a fixed rod and a movable frame. A groove is formed inside the fixed rod, and a bidirectional screw is rotatably connected inside the groove. A limiting roller is rotatably connected inside the movable frame. The beneficial effects of this utility model are: the flattening mechanism inside the housing flattens the uncoiled aluminum strip; after the aluminum strip enters the housing and is flattened, the limiting mechanism limits the aluminum strip, preventing it from shaking or deviating during the flattening process; the bidirectional screw is rotated to control the two sliders to move closer or further apart; and the distance between the two movable frames is controlled by the squeezing or pulling action of the connecting rod, thus allowing adjustment of the limiting position according to the width of the aluminum strip.

[0004] Because residual stress still exists inside the aluminum sheet after the aluminum coil is unwound, the slitting machine in the above technology only relies on the flattening mechanism to flatten the surface of the aluminum sheet, which cannot completely eliminate its internal stress. The flattened aluminum sheet may still spring back under stress, causing the sheet to bend and deform again, affecting the final flatness. Therefore, the market urgently needs to develop an efficient flattening mechanism for aluminum sheet slitting machines to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide an efficient flattening mechanism for an aluminum plate leveling machine, so as to solve the problem mentioned in the background art that, after the aluminum coil is unwound, there is still residual stress inside the aluminum plate. In the above-mentioned technology, the leveling machine only relies on the flattening mechanism to flatten the surface of the aluminum plate, which cannot completely eliminate its internal stress. The flattened aluminum plate may still spring back under stress, causing the plate to bend and deform again, affecting the final flatness.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency flattening mechanism for an aluminum plate leveling machine, comprising two supporting side plates arranged in parallel. Multiple supporting rollers are rotatably connected at equal intervals at the upper ends of the two supporting side plates. A first quartz heating tube is fixedly connected between the two supporting side plates and at the midpoint between adjacent supporting rollers. C-shaped support frames are fixedly connected to both sides of the midpoint at the upper ends of the two supporting side plates. Lifting support plates are provided at both the front and rear ends of the inner sides of the two C-shaped support frames. The upper ends of the two lifting support plates are fixedly connected by three equally spaced connecting plates. Multiple lower pressure rollers are rotatably connected at equal intervals at the lower ends of the two lifting support plates. A second quartz heating tube is fixedly connected between the two lifting support plates and at the midpoint between adjacent lower pressure rollers.

[0007] Preferably, each of the support rollers is rotatably connected to two support side plates via a first rotating shaft.

[0008] Preferably, a hydraulic rod is fixedly connected to the middle of the upper end face of each of the two C-shaped support frames, and the lower end of the telescopic end of the two hydraulic rods passes through the two C-shaped support frames and is fixedly connected to the middle of the upper end face of the two connecting plates on both sides respectively.

[0009] Preferably, each of the lower pressure rollers is rotatably connected to two lifting support plates via a second rotating shaft.

[0010] Preferably, rectangular limiting grooves are provided on both the front and rear end faces of the two C-shaped support frames, and guide rods are fixedly connected to the center of each rectangular limiting groove. Rectangular limiting sliders are fixedly connected to both sides of the center of the outer end faces of the two lifting support plates, and guide through holes are provided in the center of each rectangular limiting slider.

[0011] Preferably, the rectangular limiting sliders on the outer end faces of the two lifting support plates are respectively inserted into the two rectangular limiting slide grooves on the two C-shaped support frames, and the guide rod passes through the guide through hole in the middle of the rectangular limiting slider.

[0012] Preferably, a first arc-shaped heat collection cover is fixedly connected between the two supporting side plates and at the lower end of each first quartz heating tube, and a second arc-shaped heat collection cover is fixedly connected between the two lifting support plates and at the upper end of each second quartz heating tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, by setting a first quartz heating tube and a second quartz heating tube to heat the aluminum plate simultaneously, the aluminum plate reaches the stress release temperature during the flattening process, which can effectively eliminate the residual stress inside the aluminum plate, fundamentally solve the stress rebound problem caused by the traditional cold flattening process, and significantly improve the final flatness of the aluminum plate.

[0015] (2) In this utility model, a vertically symmetrical arrangement of support rollers and lower pressure rollers is adopted. Combined with the heat gathering effect of the first arc-shaped heat collection cover and the second arc-shaped heat collection cover, the aluminum plate is heated evenly on both sides. The heating efficiency is high and the temperature distribution is uniform, avoiding local overheating or insufficient heating.

[0016] (3) In this utility model, the structural design of the lifting support plate driven by the hydraulic rod, together with the guide mechanism of the guide rod and the rectangular limit slider, ensures the smooth operation of the flattening mechanism and the uniform distribution of the downward pressure, which can adapt to the processing requirements of aluminum plates of different thicknesses and improve the applicability and processing accuracy of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of an efficient flattening mechanism for an aluminum plate leveling machine, comprising two parallel support side plates 1. Multiple support rollers 101 are rotatably connected at equal intervals at the upper ends of the two support side plates 1. C-shaped support frames 3 are fixedly connected to the middle of the upper ends of both support side plates 1. Lifting support plates 4 are provided at both the front and rear ends of the inner sides of the two C-shaped support frames 3. The upper ends of the two lifting support plates 4 are fixedly connected by three equally spaced connecting plates 401. Hydraulic rods 301 are fixedly connected to the middle of the upper surfaces of both C-shaped support frames 3. Synchronizers are connected between the two hydraulic rods 301. The lower ends of the telescopic ends of the two hydraulic rods 301 pass through the two C-shaped support frames 3 and are fixedly connected to the middle of the upper surfaces of the two connecting plates 401 on both sides. The lower ends of the two lifting support plates 4 are rotatably connected at equal intervals. Multiple pressure rollers 5 are inserted between multiple support rollers 101 and multiple pressure rollers 5 after the aluminum coil is unwound. Two hydraulic rods 301 synchronously drive two connecting plates 401 on both sides to descend, thereby causing two lifting support plates 4 to synchronously drive multiple pressure rollers 5 to descend. The support rollers 101 and the pressure rollers 5 clamp and flatten the upper and lower ends of the aluminum plate, respectively. A first quartz heating tube 2 is fixedly connected between the two support side plates 1 and in the middle between two adjacent support rollers 101. A second quartz heating tube 6 is fixedly connected between the two lifting support plates 4 and in the middle between two adjacent pressure rollers 5. When the aluminum plate is flattened, the multiple first quartz heating tubes 2 and multiple second quartz heating tubes 6 synchronously heat the upper and lower ends of the aluminum plate, so that the aluminum plate releases stress synchronously when flattened, preventing re-coiling due to unreleased stress after flattening.

[0024] Please see Figure 3 Each support roller 101 is rotatably connected to two support side plates 1 via a first rotating shaft 102, and each pressure roller 5 is rotatably connected to two lifting support plates 4 via a second rotating shaft 501, so that the support roller 101 and the pressure roller 5 can rotate.

[0025] Please see Figure 4 Both ends of the two C-shaped support frames 3 are provided with rectangular limiting grooves 302. The center of each rectangular limiting groove 302 is fixedly connected to a guide rod 303. Both sides of the center of the outer end face of the two lifting support plates 4 are fixedly connected with rectangular limiting sliders 402. The center of each rectangular limiting slider 402 is provided with a guide hole 403. The rectangular limiting sliders 402 on the outer end face of the two lifting support plates 4 are respectively inserted into the two rectangular limiting grooves 302 on the two C-shaped support frames 3. The guide rod 303 passes through the guide hole 403 in the center of the rectangular limiting slider 402. When the two lifting support plates 4 are raised and lowered, they are guided by the rectangular limiting sliders 402 along the rectangular limiting grooves 302 and by the guide rod 303 along the guide hole 403.

[0026] Please see Figure 2 A first arc-shaped heat collection cover 201 is fixedly connected between the two supporting side plates 1 and at the lower end of each first quartz heating tube 2. A second arc-shaped heat collection cover 601 is fixedly connected between the two lifting support plates 4 and at the upper end of each second quartz heating tube 6. The heat from the first quartz heating tube 2 and the second quartz heating tube 6 is collected to the upper and lower ends of the aluminum plate by the first arc-shaped heat collection cover 201 and the second arc-shaped heat collection cover 601, respectively, thereby improving the heating efficiency.

[0027] Working Principle: During operation, the unwound aluminum sheet is guided into the gap between the support roller 101 and the lower pressure roller 5. The hydraulic rod 301 is activated, pushing the connecting plate 401 downwards, causing the lifting support plate 4 to descend smoothly along the guide rod 303. This creates clamping pressure between the lower pressure roller 5 and the support roller 101, mechanically leveling the aluminum sheet. Simultaneously, the first quartz heating tube 2 and the second quartz heating tube 6 are activated, concentrating heat onto the upper and lower surfaces of the aluminum sheet through the first arc-shaped heat collector 201 and the second arc-shaped heat collector 601. This heats the aluminum sheet to a stress release temperature range of 150-200℃ during the flattening process. During this process, residual stress inside the aluminum sheet is effectively eliminated through thermoplastic deformation. The continuous rolling conveying of the support roller 101 and the lower pressure roller 5 ensures uniform heating and pressure on the aluminum sheet. The aluminum sheet remains stable and flat after cooling, completely solving the stress rebound problem caused by traditional cold pressing.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
