Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal strip processing technology, and in particular to a metal strip heat leveling device. Background Technology
[0002] Metal strips are prone to defects such as bending and wavy deformation during rolling, transportation, or storage, requiring leveling processes to restore their flatness. Traditional leveling methods are mainly divided into two types: cold leveling and hot leveling.
[0003] Cold straightening: Relying on mechanical rolling or hydraulic straightening, although it can improve the surface flatness of the steel strip, it cannot completely eliminate the residual stress inside the material, and it may still spring back and deform during subsequent processing or use.
[0004] Hot straightening: This method involves heating and softening metal before applying pressure to straighten it, which can effectively eliminate internal stress. However, existing hot straightening equipment has the following problems:
[0005] 1) Uneven heating: Some devices only heat one side, resulting in uneven heating of the steel strip and poor leveling effect;
[0006] 2) Poor pressure control: Relying on manual experience to adjust the pressure, it is easy to cause damage to the steel strip surface due to excessive pressure or to cause incomplete leveling due to insufficient pressure;
[0007] 3) Inconvenient maintenance: The pressure plate and heating plate are fixedly connected, and the whole plate needs to be disassembled when replacing or cleaning, which is inefficient; therefore, we propose a metal steel strip heat leveling device to solve this problem. Utility Model Content
[0008] The purpose of this invention is to provide a metal steel strip heat leveling device to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A metal strip heat leveling device includes: a base plate and a plurality of leveling mechanisms disposed on the top of the base plate. The base plate is embedded with a first heating plate. Each leveling mechanism includes a pressure plate, a second heating plate, a mounting plate, and a cylinder. The top of the pressure plate has a stepped groove. The mounting plate and the second heating plate are both disposed in the stepped groove. Slide plates are slidably connected to both sides of the top of the mounting plate. A snap-on plate is fixedly connected to one side of the slide plate. Slots are formed on both inner walls of the stepped groove. Two snap-on plates are movably snapped into the corresponding slots.
[0011] Preferably, a connecting column is fixedly connected to the top of the mounting plate, a pressure sensor is fixedly connected to the top of the connecting column, and the output end of the cylinder is fixedly connected to the top of the pressure sensor.
[0012] Preferably, a fixing frame is fixedly connected to the top of the base plate, and the cylinder is fixedly installed on the top of the fixing frame;
[0013] The fixed frame has several positioning frames fixedly connected inside. The connecting column is slidably connected to the corresponding positioning frame, and a support spring is fixedly connected inside the positioning frame. The top end of the support spring is fixedly connected to the corresponding connecting column.
[0014] Preferably, the fixed frame has several connecting shafts fixedly connected inside, and abutment wheels are rotatably installed on the outer side of the connecting shafts. A trapezoidal plate is fixedly connected to the top of the slide plate, and the abutment wheels movably abut against the top of the corresponding trapezoidal plate.
[0015] Preferably, the mounting plate has grooves on both sides of its top, the sliding plate is slidably connected in the corresponding groove, and a limit rod is fixedly installed in the groove, with the sliding plate slidably sleeved on the outside of the corresponding limit rod.
[0016] Preferably, a compression spring is fixedly connected to one side of the slide plate, and the other end of the compression spring is fixedly connected to the side wall of the corresponding slide groove.
[0017] In this utility model, a metal strip heat leveling device is described. The metal strip is placed on top of a base plate, then the first heating plate is activated to heat the base plate, the second heating plate is activated to heat the pressure plate, and the cylinder is activated to drive the connecting column, mounting plate, and pressure plate downwards. The metal strip is squeezed and heated by the pressure plate and the base plate. During the heating process, the internal stress of the metal strip can be eliminated. The pressure sensor monitors the leveling force to facilitate the leveling of the steel strip. After leveling is completed, the cylinder is activated to control the mounting plate and pressure plate to reset.
[0018] In this utility model, the metal steel strip heat leveling device controls the cutting board to continue moving upward through the cylinder, so that the abutting wheel drives the sliding plate to move horizontally through the abutting with the trapezoidal plate, so that the sliding plate drives the buckle plate to disengage from the slot, release the fixation of the pressing plate, and then the pressing plate can be removed for disassembly and replacement.
[0019] This utility model has a reasonable structural design, adopting a double-sided heating design with a first heating plate embedded in the base plate and a second heating plate embedded in the pressing plate. This ensures that the steel strip is heated evenly and eliminates internal stress more thoroughly. The pressure sensor monitors the pressing force in real time to avoid over-pressure or under-pressure, thus improving the leveling accuracy. Compared with traditional manual adjustment, the flatness error is reduced. The pressing plate is fixed by the locking of the sliding plate, the buckle plate, and the slot. After leveling, the cylinder continues to lift, driving the abutment wheel to press against the trapezoidal plate, causing the buckle plate to automatically disengage. This allows for quick one-handed disassembly of the pressing plate, facilitating maintenance or replacement. Attached Figure Description

Detailed Implementation
[0025] 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.
[0026] Reference Figure 1-4 A metal strip heat leveling device includes: a base plate 1 and several leveling mechanisms disposed on the top of the base plate 1.

Slide plates 401 are slidably connected to both sides of the top of the mounting plate 4. A snap plate 402 is fixedly connected to one side of the slide plate 401. Slots are opened on both sides of the inner wall of the stepped groove. The two snap plates 402 are respectively movably snapped into the corresponding slots.
[0027] In this embodiment, a connecting post 8 is fixedly connected to the top of the mounting plate 4, and a pressure sensor 6 is fixedly connected to the top of the connecting post 8. The output end of the cylinder 5 is fixedly connected to the top of the pressure sensor 6.
[0028] In this embodiment, a fixing frame 2 is fixedly connected to the top of the base plate 1, and the cylinder 5 is fixedly installed on the top of the fixing frame 2, thereby facilitating the support and fixation of the cylinder 5.
[0029] The fixed frame 2 has several positioning frames 11 fixedly connected inside. The connecting column 8 is slidably connected to the corresponding positioning frame 11, and a support spring 7 is fixedly connected inside the positioning frame 11. The top of the support spring 7 is fixedly connected to the corresponding connecting column 8, thereby supporting the connecting column 8 and the mounting plate 4.
[0030] In this embodiment, a number of connecting shafts 9 are fixedly connected inside the fixing frame 2. Abutment wheels 10 are rotatably installed on the outer side of the connecting shafts 9. A trapezoidal plate 403 is fixedly connected to the top of the slide plate 401. The abutment wheels 10 movably abut against the top of the corresponding trapezoidal plate 403. Slide grooves are provided on both sides of the top of the mounting plate 4. The slide plate 401 is slidably connected in the corresponding slide groove. A limit rod is fixedly installed in the slide groove. The slide plate 401 is slidably sleeved on the outer side of the corresponding limit rod to guide and limit the slide plate 401.
[0031] In this embodiment, a compression spring 404 is fixedly connected to one side of the slide plate 401, and the other end of the compression spring 404 is fixedly connected to the side wall of the corresponding slide groove.
[0032] In this embodiment, during use, the metal steel strip is placed on top of the base plate 1, and then the first heating plate 101 is activated to heat the base plate 1, the second heating plate 301 is activated to heat the pressure plate 3, and the cylinder 5 is activated to drive the connecting column 8, the mounting plate 4, and the pressure plate 3 to move downwards.
