Description

Technical Field

[0001] The utility model relates to the technical field of metal plate straightening, in particular to a cold and hot straightening device for metal plates. Background Art

[0002] Metal sheets are widely used in fields such as rail transportation and aerospace. As a practical material, metal sheets have the advantages of low density, good electrical and thermal conductivity, good ductility and recyclability. However, in actual use, metal sheets are often prone to plastic deformation due to collision or extrusion. When metal sheets need to be recycled and reused, they need to be straightened by hot and cold methods. Currently, most metal sheets are straightened by large roller straighteners, but roller straighteners are expensive to manufacture, bulky in size and have high maintenance costs.

[0003] In the related art, in order to save space and cost, the straightening device is miniaturized, and a first slide groove is opened on one side of the support plate, and a cross bar is connected inside the first slide groove to facilitate lateral movement. A second slide groove is opened on the outer surface of the cross bar to facilitate longitudinal position adjustment of the straightening mechanism, so that it can be positioned at any position on the upper surface of the equipment table to straighten multiple deformations of the plate. However, the straightening device can only be used for cold straightening of metal plates, and cannot be used for hot straightening of metal plates. Hot straightening requires hot straightening treatment through a hot straightening device, and cannot meet the needs of cold and hot straightening of metal plates at the same time, and has a small scope of application. Utility Model Content

[0004] The purpose of the utility model is to provide a hot and cold straightening device for metal plates to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A hot and cold straightening device for metal plates, comprising:

[0007] A first substrate, wherein a plurality of supporting legs are disposed at a lower portion of the first substrate;

[0008] A second substrate is disposed on the upper portion of the first substrate;

[0009] The first substrate and the second substrate are respectively provided with a plurality of threaded holes, and the first substrate and the second substrate are detachably connected by bolts;

[0010] The first substrate and the second substrate are both made of austenitic chromium-nickel stainless steel.

[0011] The hot and cold straightening device for metal sheets according to this solution has at least the following technical effects:

[0012] The hot and cold straightening device for metal plates presses the metal plates between a first substrate and a second substrate for hot and cold straightening treatment. Since the first substrate and the second substrate are detachably connected by bolts, and both the first substrate and the second substrate are made of austenitic chromium-nickel stainless steel, the austenitic chromium-nickel stainless steel is specifically model 310S, and its melting point is 1470°C, which has good high temperature resistance, so that the device can be continuously used at a high temperature of 900°C, and can meet the needs of hot and cold straightening of metal plates respectively; the hot and cold straightening device for metal plates has a simple structure and is easy to operate, can eliminate or reduce deformations such as bending and twisting of metal plates, improve the quality and performance of metal plates, and has a wide range of applications and low maintenance costs.

[0013] As a further solution of the present invention: the thickness of the first substrate and the second substrate are both set to 5mm-7mm.

[0014] Since the thickness of the first substrate and the second substrate are both set to 5mm-7mm, the strength and stability of the first substrate and the second substrate can be maintained, the requirements of cold and hot straightening of the metal sheet can be met respectively, and the straightening effect of the metal sheet can be ensured.

[0015] As a further solution of the present invention: the weight of the first substrate is 6.4 kg-6.8 kg.

[0016] Since the weight of the first substrate is 6.4 kg-6.8 kg, it can provide sufficient support force for the second substrate to avoid shaking or vibration when the second substrate is pressed on the first substrate, ensuring that the device is more firm and stable during straightening.

[0017] As a further solution of the present invention: the weight of the second substrate is 6.4 kg-6.8 kg.

[0018] Since the weight of the second substrate is 6.4 kg-6.8 kg, it can provide sufficient pressure for the metal sheet, which can meet the needs of cold and hot straightening of the metal sheet, thereby improving the applicability of the device.

[0019] As a further solution of the utility model: the number of the supporting legs is 5.

[0020] As a further solution of the utility model: the five supporting legs are respectively arranged at the four corners and the center of the bottom of the first substrate.

[0021] Since there are five supporting legs, which are respectively arranged at the four corners and the center of the bottom of the first substrate, the five supporting legs can provide more uniform supporting force, which can effectively disperse the weight of the first substrate and the second substrate, ensuring that the device maintains stability and balance when straightening the metal plate, thereby ensuring the straightening effect and quality of the metal plate.

[0022] As a further solution of the utility model: the first substrate and the five supporting legs are welded by electron beam.

[0023] The first substrate and the five supporting legs are electron beam welded to ensure the stability and reliability of the welding points between the first substrate and the supporting legs, avoid loosening of the supporting legs due to the weight of the substrate, ensure the structural strength and stability of the device, and thus ensure the straightening effect of the metal sheet.

[0024] As a further solution of the utility model: handles are respectively provided on the top of the second substrate, and the handles are welded to the top of the second substrate by electron beam welding.

[0025] Since a handle is provided on the top of the second substrate and the handle and the top of the second substrate are welded by electron beam, it is easier to separate the second substrate from the first substrate, thereby preventing the risk of accidental slipping or falling during the separation process due to the excessive weight of the substrate, thereby ensuring the operational flexibility and safety of the device.

The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0037] like Figure 1 and Figure 2 The embodiment of the utility model shown is a hot and cold straightening device for metal plates, comprising: a first substrate 101, a plurality of supporting legs 102 are arranged at the bottom of the first substrate 101; a second substrate 103 is arranged on the top of the first substrate 101; the first substrate 101 and the second substrate 103 are respectively provided with a plurality of threaded holes 104, and the first substrate 101 and the second substrate 103 are detachably connected by bolts; the first substrate 101 and the second substrate 103 are both made of austenitic chromium-nickel stainless steel.

[0038] When in use, metal sheets of different thicknesses are pressed between the first substrate 101 and the second substrate 103, and the first substrate 101 and the second substrate 103 are locked and fixed by bolts to achieve cold straightening; while in hot straightening, metal sheets of different thicknesses are pressed between the first substrate 101 and the second substrate 103, and the first substrate 101 and the second substrate 103 are locked and fixed by bolts, and the whole device is placed in a box-type resistance furnace, and the metal sheet is heated to a certain temperature and kept warm for a certain time by using creep forming technology and heat treatment softening technology, so that it becomes softer and easier to deform. In the heat-insulating state, the metal sheet is hot-straightened by the device.

[0039] Specifically, the hot and cold straightening device for metal plates presses the metal plates between the first substrate 101 and the second substrate 103 for hot and cold straightening treatment. Since the first substrate 101 and the second substrate 103 are detachably connected by bolts, and the first substrate 101 and the second substrate 103 are both made of austenitic chromium-nickel stainless steel, the austenitic chromium-nickel stainless steel is specifically model 310S, and its melting point is 1470°C, and it has good high temperature resistance, so that the device can be continuously used at a high temperature of 900°C, which can meet the needs of hot and cold straightening of metal plates respectively; the hot and cold straightening device for metal plates has a simple structure and is easy to operate, can eliminate or reduce deformations such as bending and twisting of metal plates, improve the quality and performance of metal plates, and has a wide range of applications and low maintenance costs.

[0040] Furthermore, the thickness of the first substrate 101 and the second substrate 103 are both set to 5 mm-7 mm.

[0041] Specifically, since the thickness of the first substrate 101 and the second substrate 103 are both set to 5mm-7mm, the strength and stability of the first substrate 101 and the second substrate 103 can be maintained, and the requirements of hot and cold straightening of metal sheets can be met respectively, thereby ensuring the straightening effect of the metal sheets.

[0042] Further, the weight of the first substrate 101 is 6.4 kg to 6.8 kg.

[0043] Specifically, since the weight of the first substrate 101 is 6.4 kg-6.8 kg, it can provide sufficient support force for the second substrate 103 to avoid shaking or vibration when the second substrate 103 is pressed on the first substrate 101, ensuring that the device is more firm and stable during straightening.

[0044] Furthermore, the weight of the second substrate 103 is 6.4 kg to 6.8 kg.

[0045] Specifically, since the weight of the second substrate 103 is 6.4 kg-6.8 kg, it can provide sufficient pressure for the metal plate, and can meet the requirements of hot and cold straightening of the metal plate, thereby improving the applicability of the device.

[0046] like Figure 1 As shown, there are five supporting legs 102 ; the five supporting legs are respectively arranged at the four corners and the center of the bottom of the first substrate 101 .

[0047] Specifically, since there are five supporting legs 102, the five supporting legs are respectively arranged at the four corners and the center of the bottom of the first substrate 101, so that the five supporting legs 102 can provide a more uniform supporting force, and can effectively disperse the weight of the first substrate 101 and the second substrate 103, ensuring that the device maintains stability and balance when straightening the metal plate, thereby ensuring the straightening effect and quality of the metal plate.

[0048] Furthermore, the first substrate 101 and the five supporting legs 102 are welded by electron beam.

[0049] Specifically, the first substrate 101 and the five supporting legs 102 are electron beam welded to ensure the stability and reliability of the welding points between the first substrate 101 and the supporting legs 102, avoid loosening of the supporting legs 102 due to the weight of the substrate, ensure the structural strength and stability of the device, and thus ensure the straightening effect of the metal sheet.

[0051] Specifically, since a handle 105 is provided on the top of the second substrate 103, the handle 105 and the top of the second substrate 103 are welded by electron beam, which makes it easier to separate the second substrate 103 from the first substrate 101, thereby preventing the risk of accidental slipping or falling during the separation process due to the excessive weight of the substrate when separating the second substrate 103, thereby ensuring the operational flexibility and safety of the device.

[0052] It should also be noted that the hot and cold straightening device for metal sheets is suitable for cold straightening metal sheets with a thickness of 1mm-20mm and hot straightening metal sheets with a thickness of 2mm-40mm, thereby increasing the thickness range of cold and hot straightening metal sheets.
