Description

Technical Field

[0001] The invention relates to the technical field of metal foil straightening machines, and in particular to a longitudinal arrangement structure of a roller box of a metal foil straightening machine. Background Art

[0002] After rolling, the metal foil needs to be straightened by a straightening machine. The straightening rollers of the existing metal foil straightening machine are arranged in a staggered and horizontal manner (see the attached manual). Figure 1 ), when straightening the metal foil, the metal foil passes through the straightening roller boxes that are staggered and arranged horizontally, and is repeatedly bent and deformed, thereby improving the straightness of the metal foil and eliminating some of the residual stress after rolling. The problem with this horizontal arrangement of the straightening roller boxes is that the working rollers of the straightening roller boxes located at the top naturally bend and deform under the action of gravity, especially as the thickness of the metal foil becomes thinner and the diameter of the working rollers becomes thinner, the bending deformation becomes more serious; and the metal foil is extremely thin, so the tension during straightening is also small (excessive tension will cause The smaller tension can no longer completely overcome the flexural deformation of the working roll. Therefore, when the metal foil is straightened at a higher speed, the flexurally deformed working roll will vibrate. As a result, vibration marks will appear on the metal foil after straightening, which seriously affects the quality of the straightened metal foil. In the straightening process, the strip may even break frequently, making it impossible to carry out continuous production. If the metal foil is straightened at a slow speed, the production efficiency will be extremely low, which will seriously affect the economic benefits of the enterprise. Therefore, this problem has become an insurmountable technical difficulty in the high-speed straightening production of metal foil. Summary of the Invention

[0003] In order to overcome the shortcomings of the background technology, the present invention discloses a longitudinal arrangement structure of roller boxes of a metal foil straightening machine. The straightening roller boxes are fixedly arranged in a longitudinal manner to ensure that the working rollers of all the straightening roller boxes are located on the upper part of the middle roller; by changing the arrangement of the straightening roller boxes, the working rollers of the straightening roller boxes are avoided from flexural deformation, thereby solving the chattering problem and belt breakage accident in the high-speed straightening of metal foil, and greatly improving the economic benefits of the enterprise.

[0004] In order to achieve the above-mentioned purpose of the invention, the present invention adopts the following technical scheme: a longitudinal arrangement structure of a roller box of a metal foil straightening machine, comprising a straightening machine body, a straightening roller box, a roller box support, and a deflector roller, wherein a plurality of roller box supports are longitudinally arranged and fixed on the straightening machine body, and the straightening roller box is fixed on the upper part of the roller box support, thereby constituting a longitudinal arrangement structure of the straightening roller box; the deflector roller is rotatably arranged on the feed side and the discharge side of the straightening roller box to change the direction of the metal foil so that the metal foil passes through each straightening roller box in turn; the longitudinal arrangement structure of the straightening roller box can ensure that the working rollers of all the straightening roller boxes are located on the upper part of the intermediate roller. Due to the support of the intermediate roller, the working rollers of the straightening roller boxes are prevented from flexural deformation, thereby solving the chattering problem and the belt break accident existing in the high-speed straightening of metal foil.

[0005] Furthermore, the straightening machine body is a plate structure, and the roller box support is arranged longitudinally and fixedly set on the plate surface on one side of the straightening machine body; a material trough is provided on the plate surface of the straightening machine body, which is used to pass the metal foil when the metal foil straightening machine is working; the plate structure of the straightening machine body has the advantage of low cost.

[0006] Preferably, the straightening machine body is a rectangular frame structure; the straightening machine body adopts a rectangular frame structure with the advantages of high rigidity and good stability, which can fully ensure the long-term stability of the metal foil straightening machine; a roller box cavity is provided in the middle of the straightening machine body with a rectangular frame structure, and there are two types of roller box cavity settings: one is that the depth direction of the roller box cavity is parallel to the axis of the straightening roller box (see the attached manual). Figure 2 ), the other box cavity depth direction is perpendicular to the axis of the straightening roller box (see the instructions attached Figure 10 ).

[0007] Furthermore, the upper and lower positions of the deflector roller are fixed; when the deflector roller is fixed in this way, when the metal foil passes through each straightening roller box, the wrap angle between the metal foil and the straightening roller is fixed and cannot be adjusted. This deflector roller fixing method is suitable for manufacturers with a relatively uniform metal foil thickness.

[0008] Preferably, the upper and lower positions of the deflector rollers can be adjusted; this fixing method of the deflector rollers is relatively complicated, but when the metal foil passes through each straightening roller box, the wrap angle between the metal foil and the straightening roller can be adjusted, so it is suitable for manufacturers with a large range of metal foil thickness variations.

[0009] Furthermore, an oil spraying structure is provided on the straightening machine body. During the straightening process of the metal foil, washing oil is sprayed onto the metal foil through the oil spraying structure to improve the metal chips and debris remaining on the surface of the metal foil.

[0010] Furthermore, tensioning roller groups are provided outside the feed-side deflection roller and the discharge-side deflection roller, and the tensioning roller groups outside the feed-side deflection roller and the discharge-side deflection roller have the same structure.

[0011] Furthermore, the tensioning roller group includes two tensioning rollers; the relative positions of the two tensioning rollers in the two tensioning roller groups arranged outside the feed side guide roller and the discharge side guide roller are set to be the same; this structural design actually reduces the processing cost of the tensioning roller group because the structures of the tensioning roller groups outside the feed side guide roller and the discharge side guide roller are exactly the same.

[0012] Due to the adoption of the technical solution as described above, the present invention has the following beneficial effects: the present invention discloses a longitudinal arrangement structure of the roller box of a metal foil straightening machine, comprising a straightening machine body, a straightening roller box, a roller box support, and a deflector roller; a plurality of roller box supports are longitudinally arranged and fixed on the straightening machine body, and the straightening roller box is fixed on the upper part of the roller box support, thereby constituting a longitudinal arrangement structure of the straightening roller box; the deflector roller is rotatably arranged on the feed side and the discharge side of the straightening roller box to change the direction of the metal foil so that the metal foil passes through each straightening roller box in turn; the longitudinal arrangement structure of the straightening roller box can ensure that the working rollers of all the straightening roller boxes are located on the upper part of the intermediate roller. Due to the support of the intermediate roller, the working rollers of the straightening roller boxes are avoided from flexural deformation, thereby solving the chattering problem and belt breakage accident existing in the high-speed straightening of metal foil, and greatly improving the economic benefits of the enterprise.

[0024] The present invention can be explained in detail by the following examples, the purpose of which is to disclose the present invention and to protect all technical improvements within the scope of the present invention. Example 1:

[0025] A longitudinal arrangement structure of roller box of metal foil straightening machine, see the attached manual Figure 2 、 3 : It includes a straightening machine body 1, a straightening roller box 2, a roller box support 3, a deflection roller 4, and a tensioning roller group 7;

[0026] See the instructions attached Figure 4 : The straightening machine body 1 is a rectangular frame structure, with a roller box cavity 1.1 in the middle and five feeding slots 1.2 on the left and right side walls of the roller box cavity 1.1; see the attached manual Figure 5 :The straightening roller box 2 is a six-roller straightening roller box, which is the existing technology, including a working roller 2.1, two intermediate rollers 2.2, three support rollers 2.3, and a roller seat 2.4. The working roller 2.1, the intermediate roller 2.2, and the support roller 2.3 are rotatably arranged on the roller seat 2.4, wherein the intermediate roller 2.2 and the support roller 2.3 support the working roller 2.1 to prevent the working roller 2.1 from being deformed during the working process; see the attached manual Figure 6 : The roller box holder 3 is a thick plate with a positioning groove 3.1 in the middle of the upper plate;

[0027] See the instructions attached Figure 2 、 3: Five roller box supports 3 are arranged longitudinally, arranged in parallel, and fixedly arranged in the roller box cavity 1.1 of the straightening machine body 1, and the length direction of the roller box support 3 is parallel to the depth direction of the roller box cavity 1.1; the straightening roller box 2 is fixedly arranged in the positioning groove 3.1 of the roller box support 3, and the axis of the working roller 2.1 is parallel to the depth direction of the roller box cavity 1.1; there are two groups of deflection rollers 4, each group of deflection rollers 4 is provided with three, and bearing seats are provided at both ends of the deflection roller 4, and a guide rail slider is provided on the side of each bearing seat, and a deflection roller lifting mechanism 5 is fixedly provided on the upper end surface of each bearing seat, and the two deflection roller lifting mechanisms 5 are connected by a synchronous shaft; one group of deflection rollers 4 is connected by a guide rail slider The block is slidably connected to the guide groove on the left side of the straightening machine body 1, and the deflection roller lifting mechanism 5 is fixedly connected to the left side of the straightening machine body 1 through a bracket; the deflection roller lifting mechanism 5 is provided with an adjustment shaft. When the adjustment shaft is rotated, the deflection roller lifting mechanism 5 drives the deflection roller 4 to slide up and down along the guide groove, and the synchronization shaft ensures that the bearing seats at both ends of the deflection roller 4 slide up and down synchronously; another group of deflection rollers 4 is arranged on the right side of the straightening machine body 1, and the connection method of the two deflection rollers 4 on the upper part and the straightening machine body 1 is the same as that of the deflection roller 4 on the left side. The lowest deflection roller 4 is provided with a left-right symmetrical guide rail guide structure, and its lifting movement is driven by the discharge deflection roller elevator 6;

[0028] An oil spray structure 8 is also fixedly installed in the roll box cavity 1.1. The oil spray structure 8 includes an oil spray pipe and a plurality of oil spray nozzles evenly distributed on the upper portion of the oil spray pipe. The oil spray pipe is parallel to the axis of the working roll 2.1 of the straightening roll box 2. There are five oil spray structures 8 in total. The oil spray structures 8 are arranged on the feed side of the adjacent straightening roll box 2, below the metal foil 9.

[0029] There are two sets of tension roller groups 7, each set of tension roller groups 7 includes two tension rollers 7.1; the two sets of tension roller groups 7 are fixedly arranged on the left and right sides of the straightening machine body 1, as shown in the attached manual. Figure 1 Compared with the two sets of tensioning roller groups 7, the tensioning rollers 7.1 in the two sets of tensioning roller groups 7 in this embodiment have the same relative positions and are non-mirror-symmetrical.

[0030] When the metal foil straightening machine is working, the metal foil 9 generates straightening tension through the tensioning roller group 7 arranged on the left and right sides of the straightening machine body 1, and the metal foil 9 changes direction through the deflection rollers 4 on the left and right sides of the straightening machine body 1 in turn, so that the metal foil 9 generates a wrap angle at the working roller 2.1 of each straightening roller box 2. When the metal foil 9 passes through each working roller 2.1, it bends and deforms, thereby improving the straightness of the metal foil 9 and eliminating some residual stress after rolling; by adjusting the upper and lower positions of the deflection roller 4, the wrap angle of the metal foil 9 at the working roller 2.1 is changed to adapt to metal foils 9 of different thicknesses; when the metal foil 9 is straightened, the oil spraying structure 8 sprays washing oil to coat the metal foil The lower surface of the metal foil 9 is actually cleaned with oil on both the upper and lower surfaces through the five oil spraying structures 8, thereby removing metal chips and foreign matter on the upper and lower surfaces of the metal foil 9; in the present invention, since the working rollers 2.1 of the straightening roller box 1 are all located on the upper part of the intermediate roller 2.2, the working rollers 2.1 are supported by the intermediate roller 2.2, thereby avoiding bending deformation, thereby solving the chattering problem and belt breakage accident in the high-speed straightening of the metal foil, and greatly improving the straightening speed and quality of the metal foil 9; in the present invention, the diameter of the working roller 2.1 is reduced from the original 30mm to 12mm, so it can adapt to the straightening work of the metal foil 9 with a minimum thickness of 0.012mm. Example 2:

[0031] See the instructions attached Figure 7 In this embodiment, five straightening roller boxes 2 are arranged longitudinally and parallely and fixed in the roller box cavity 1.1 of the straightening machine body 1, but an angle is set between the plane where the axis of the working rollers 2.1 of the straightening roller box 2 is located and the horizontal plane. Example 3:

[0032] See the instructions attached Figure 8 In this embodiment, five straightening roller boxes 2 are arranged longitudinally and in parallel and fixedly arranged in the roller box cavity 1.1 of the straightening machine body 1, but the axes of the working rollers 2.1 of the straightening roller boxes 2 are arranged in a staggered manner. Example 4:

[0033] See the instructions attached Figure 9 In this embodiment, the straightening machine body 1 is a flat plate structure, a material trough 1.2 is provided on the flat plate, and the roller box holder 3 is arranged longitudinally and fixedly set on a side plate of the straightening machine body 1. Example 5:

[0034] See the instructions attached Figure 10 In this embodiment, the straightening machine body 1 is a frame-shaped structure, but the depth direction of the roller box cavity 1.1 in the middle of the straightening machine body 1 is perpendicular to the axis of the working roller 2.1 of the straightening roller box 2.

[0035] The parts not described in detail in this invention are prior art.
