Description

Technical Field

[0001] This utility model relates to the field of cold-rolled sheet processing technology, and more specifically, to a cold-rolled sheet tensioning and straightening device. Background Technology

[0002] In the field of sheet metal processing, cold-rolled sheets are widely used in industries such as automobile manufacturing, home appliances, and construction due to their excellent surface quality, dimensional accuracy, and mechanical properties. During the production process, cold-rolled sheets often exhibit shape defects (such as wavy edges, warping, and camber) due to the rolling process, temperature variations, and internal residual stress, affecting subsequent processing and performance. Therefore, tension straightening is a crucial process for improving the shape of cold-rolled sheets.

[0003] In the prior art, such as the tension leveling device for cold-rolled stainless steel sheet disclosed in CN211915046U, the tension leveling device includes a first support column, a second support column inserted inside the first support column, a connecting frame between the two transverse second support columns, a placement plate on the upper side of the connecting frame, a fixed roller on the inner side of the connecting frame, a turntable on the right side of the placement plate, a rotating shaft at the center of the turntable, a protrusion on one side of the turntable, and a movable rod sleeved on the outer side of the protrusion. However, in the actual processing and use of the above-mentioned tension leveling device, the stressed part of the cold-rolled sheet will heat up during tension leveling. If the stressed part cannot be cooled down quickly, the cold-rolled sheet under high temperature is prone to deformation again, ultimately affecting the yield. Utility Model Content

[0004] Therefore, in order to solve the problem that cold-rolled sheets are prone to deformation again due to the inability to cool down quickly in the stressed parts, this utility model provides a cold-rolled sheet tension leveling device, the specific technical solution of which is as follows:

[0005] A cold-rolled sheet straightening device includes a processing table and a straightening apparatus. A feeding rack, a processing rack, and a discharging rack are sequentially connected to the processing table along the conveying direction of the cold-rolled sheet. The feeding rack is equipped with a detection head that can be raised and lowered relative to the processing table. Limiting structures are provided between the feeding rack and the processing rack, and between the processing rack and the discharging rack. The straightening apparatus is mounted on the processing rack and includes a positioning roller and a support roller arranged vertically. The positioning roller can be raised and lowered relative to the processing rack. A positioning gap is formed between the positioning roller and the support roller for the cold-rolled sheet to pass through. A cooling channel is formed inside the support roller, and the cooling channel is filled with coolant.

[0006] The aforementioned cold-rolled sheet straightening equipment, by being equipped with a feed rack and an discharge rack, facilitates the feeding and unloading of cold-rolled sheets before and after straightening, thereby improving processing efficiency. By incorporating a detection head that reciprocates against the cold-rolled sheet on the feed rack, it performs mechanical property testing on the sheet to be processed, ensuring that mechanical performance failures do not occur during the straightening process. The positioning gap, achieved by adjusting the installation height of the positioning rollers, allows for control over the size of the positioning gap, thus adapting to cold-rolled sheets of different sizes and thicknesses and expanding its applicability. Furthermore, the cooling channel, with its coolant cooling the cold-rolled sheet on the support rollers during rotation, solves the problem of insufficient cooling of stressed areas, which can easily lead to re-deformation.

[0007] Furthermore, the feeding rack is equipped with a detection component, which includes a sliding seat, a first driving member, and a lifting seat. A transverse track is fixedly installed on the top of the feeding rack, and the sliding seat is slidably mounted on the transverse track. The first driving member and the lifting seat are both installed on the sliding seat, and the lifting seat can be raised and lowered relative to the sliding seat. The first driving member is connected to the lifting seat in a transmission manner, and the detection head is inserted into the lifting seat.

[0008] Furthermore, the detection assembly also includes an abutment located on one side of the detection head, one end of which is threadedly fixed to the lifting seat, and the other end of which is provided with a contact roller for abutting against the upper surface of the cold-rolled plate.

[0009] Furthermore, the limiting structure includes two limiting components symmetrically arranged on both sides of the processing frame, and a limiting space is formed between the two limiting components for the cold-rolled sheet to pass through.

[0010] Furthermore, the limiting assembly includes a drive rod, a limiting roller, a second drive member, and a mounting base inserted into the side wall of the processing frame. One end of the drive rod is slidably inserted into the mounting base, and the other end of the drive rod is fixedly connected to the limiting roller. The second drive member is mounted on the mounting base and is used to control the sliding state of the drive rod.

[0011] Furthermore, the bottom of the discharge rack is provided with telescopic feet, which can swing relative to the discharge rack.

[0012] Furthermore, the straightening device also includes a drive structure mounted on the processing table. The drive structure is located on one side of the processing frame and is used to control the rotation state of the positioning roller and the rotation state of the support roller, respectively.

[0013] Furthermore, the tension straightening device also includes a control module fixed to the top of the processing frame, the control module being used to control the opening and closing state of the drive structure.

[0014] Furthermore, the support roller includes a roller body and a rotating shaft rotatably mounted on the processing frame. The roller body is sleeved on the outer surface of the rotating shaft. Both ends of the roller body are fixed on the rotating shaft by bearings and flanges. The cooling groove is formed on the axial surface of the roller body.

[0015] Furthermore, rotary joints are installed on the flanges at both ends of the rotating shaft, and liquid inlet pipes and liquid outlet pipes are respectively connected to the rotary joints. Both the liquid inlet pipes and the liquid outlet pipes are connected to the cooling channel. Attached Figure Description

[0026] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0027] like Figures 1-5 As shown, a cold-rolled sheet straightening device according to one embodiment of the present invention includes a processing table and a straightening device. A feeding rack 1, a processing rack 2, and a discharging rack 3 are sequentially connected on the processing table along the conveying direction of the cold-rolled sheet. The feeding rack 1 is equipped with a detection head 11 that can be raised and lowered relative to the processing table. Limiting structures 4 are provided between the feeding rack 1 and the processing rack 2, and between the processing rack 2 and the discharging rack 3. The straightening device is installed on the processing rack 2 and includes a positioning roller 5 and a support roller 6 arranged vertically. The positioning roller 5 can be raised and lowered relative to the processing rack 2. A positioning gap is formed between the positioning roller 5 and the support roller 6 for the cold-rolled sheet to pass through. A cooling channel 611 is opened inside the support roller 6, and the cooling channel 611 is filled with coolant.

[0028] The aforementioned cold-rolled sheet straightening equipment, by being equipped with a feeding rack 1 and a discharging rack 3, facilitates the feeding and discharging of cold-rolled sheets before and after straightening, thereby improving processing efficiency. By being equipped with a detection head 11, which reciprocates to contact the cold-rolled sheet on the feeding rack 1, the equipment performs mechanical property testing on the cold-rolled sheet to be processed, ensuring that it does not experience mechanical property failure during the straightening process. By being equipped with a positioning gap, the installation height of the positioning roller 5 can be adjusted to control the size of the positioning gap, thus adapting to cold-rolled sheets of different sizes and thicknesses, which improves its applicability. By being equipped with a cooling channel 611, the coolant in the cooling channel 611 cools the cold-rolled sheet on the support roller 6 during rotation, solving the problem that the stressed parts of the cold-rolled sheet cannot be cooled quickly and are prone to deformation again.

[0029] Preferably, the detection head 11 is a compressive strength test probe. The probe directly applies pressure to the cold-rolled sheet to be processed, simulating the load conditions during actual processing. By applying different pressures, the mechanical properties and strength of the cold-rolled sheet can be evaluated.

[0030] like Figure 3 and Figure 4 As shown, in one embodiment, a detection assembly is provided on the feed rack 1. The detection assembly includes a sliding seat 12, a first driving member 13, and a lifting seat 14. A transverse rail 15 is fixedly installed on the top of the feed rack 1. The sliding seat 12 is slidably mounted on the transverse rail 15. The first driving member 13 and the lifting seat 14 are both mounted on the sliding seat 12. The lifting seat 14 can rise and fall relative to the sliding seat 12. The first driving member 13 is connected to the lifting seat 14 in a transmission manner. The detection head 11 is inserted into the lifting seat 14. By providing the first driving member 13, the first driving member 13 drives the lifting seat 14 to rise and fall, thereby enabling the detection head 11 to reciprocate away from and abut against the cold-rolled plate, thus completing the detection operation of the cold-rolled plate.

[0031] Specifically, the transverse track 15 is set in a horizontal direction.

[0032] Preferably, the first driving component 13 is a driving cylinder.

[0033] like Figure 4 As shown, in one embodiment, the detection assembly further includes an abutment 16 located on one side of the detection head 11. One end of the abutment 16 is threaded onto the lifting seat 14, and the other end of the abutment 16 is provided with a contact roller 161 for abutting against the upper surface of the cold-rolled sheet. The contact roller 161 is configured to limit the descent of the detection head 11. When the contact roller 161 descends to press against the surface of the cold-rolled sheet,

[0034] In one embodiment, the limiting structure 4 includes two limiting components symmetrically arranged on both sides of the processing rack 2, forming a limiting space between the two limiting components for the cold-rolled sheet to pass through. The limiting space is adjusted according to the size of the cold-rolled sheet to ensure the stability of the cold-rolled sheet during transportation and to prevent it from shifting or even falling off, which would affect subsequent tensioning and straightening processes.

[0035] like Figure 2 and Figure 4As shown, in one embodiment, the limiting assembly includes a drive rod 41, a limiting roller 42, a second drive member 43, and a mounting base 44 inserted into the side wall of the processing frame 2. One end of the drive rod 41 is slidably inserted into the mounting base 44, and the other end of the drive rod 41 is fixedly connected to the limiting roller 42. The second drive member 43 is mounted on the mounting base 44 and is used to control the sliding state of the drive rod 41. By providing the second drive member 43, the second drive member 43 drives the drive rod 41 to slide, thereby controlling the position adjustment of the limiting roller 42, and thus adapting to cold-rolled sheets of different sizes.

[0036] Preferably, the second driving component 43 is a drive motor.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment, the bottom of the discharge rack 3 is provided with a telescopic support 31, which can swing relative to the discharge rack 3 to adapt to different installation heights or angles.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the straightening device further includes a drive structure 7 mounted on the processing table. The drive structure 7 is disposed on one side of the processing frame 2 and is used to control the rotation state of the positioning roller 5 and the rotation state of the support roller 6 respectively.

[0039] Preferably, the drive structure 7 is a combination of multiple drive motors, which can simultaneously control the rotation state of the positioning roller 5 and the rotation state of the support roller 6.

[0040] like Figures 1-3 As shown, in one embodiment, the straightening device further includes a control module 21 fixed to the top of the processing frame 2. The control module 21 is used to control the opening and closing state of the drive structure 7.

[0041] like Figure 2 and Figure 5 As shown, in one embodiment, the support roller 6 includes a roller body 61 and a rotating shaft 62 rotatably mounted on the processing frame 2. The roller body 61 is sleeved on the outer surface of the rotating shaft 62, and both ends of the roller body 61 are fixed to the rotating shaft 62 by the cooperation of bearings 63 and flanges 64. Cooling grooves 611 are formed on the axial surface of the roller body 61. During the tension straightening process, the rotation of the rotating shaft 62 allows the cold-rolled plate on the roller body 61 to move forward. During the rotation of the support roller 6, the coolant in the cooling grooves 611 continuously cools the cold-rolled plate.

[0042] like Figure 5As shown, in one embodiment, rotary joints 65 are installed on flanges 64 at both ends of the rotating shaft 62. Inlet pipes 66 and outlet pipes 67 are connected to the rotary joints 65, respectively, and both are connected to the cooling channel 611. Compared with the prior art, this eliminates the need for water spraying and air drying operations, improving processing efficiency.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
