Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting equipment technology, and in particular to a cutting device for cold-rolled low-carbon steel strip. Background Technology
[0002] Cold-rolled low-carbon steel strip refers to a narrow and long steel plate (thickness: 0.10mm-0.30mm) manufactured to meet the needs of various industrial production of metal or mechanical products. Due to its excellent tensile strength, yield strength, and gloss, it is widely used in the stamping of components for smart wearable products. To meet the manufacturing requirements of different parts or products, cold-rolled low-carbon steel strip needs to be cut to specific widths; therefore, we urgently need a cutting device for cold-rolled low-carbon steel strip.
[0003] Currently, the cutting method for cold-rolled low-carbon steel strip is as follows: the strip is cut using a cutting tool, and then wound up using a second winding machine. However, because the cut strip is not separated, it overlaps (since the strip is very thin, it will overlap if it is not separated in time after cutting), which will affect the subsequent winding up. Utility Model Content
[0004] In response to the shortcomings of the existing production technology, the applicant provides a cutting device for cold-rolled low-carbon steel strip. By improving the structure of the cutting device, the cut cold-rolled low-carbon steel strips are separated from each other and do not interfere with each other, thereby improving the coiling effect of the cut cold-rolled low-carbon steel strips.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A cutting device for cold-rolled low-carbon steel strip includes: an unwinding mechanism, a cutting mechanism, a guide roller, a separating roller, a first winding mechanism, and a second winding mechanism arranged sequentially along the moving direction of the cold-rolled low-carbon steel strip. The unwinding mechanism, the guide roller, and the second winding mechanism are on the same horizontal line. The separating roller is located below the guide roller, and the first winding mechanism is located below the separating roller. After being cut by the cutting mechanism and guided by the guide roller, a portion of the cold-rolled low-carbon steel strip passes through the separating roller and is wound by the first winding mechanism, while another portion of the cold-rolled low-carbon steel strip is directly wound by the second winding mechanism.
[0007] Therefore, the separating rollers can separate the cut cold-rolled low-carbon steel strips, so that the cut cold-rolled low-carbon steel strips are separated from each other and do not interfere with each other. After cutting, the two parts of the cold-rolled low-carbon steel strips are wound up by the first winding mechanism and the second winding mechanism respectively, so as to improve the winding effect of the cut cold-rolled low-carbon steel strips.
[0008] As a further improvement to the above technical solution, it also includes: a base plate, wherein the unwinding mechanism, the cutting mechanism, the guide roller, the separating roller, the first winding mechanism, and the second winding mechanism are all connected to the base plate.
[0009] As a further improvement to the above technical solution: the unwinding mechanism includes: a first driving member and an expansion shaft, the first driving member being connected to the base plate via a first connecting block, and the driving end of the first driving member being connected to the expansion shaft.
[0010] As a further improvement to the above technical solution: the cutting mechanism comprises a cutting blade, a first driving unit, and two second driving units. The cutting blade is rotatably connected to the first driving unit via a bearing. The first driving unit is connected to the telescopic end of the second driving unit, and the second driving unit is connected to the base plate. The two second driving units are arranged opposite to each other. The first driving unit drives the cutting blade to move along the X-axis, and the second driving units drive the cutting blade to move along the Z-axis. Thus, the first driving unit can control the movement of the cutting blade in the X-axis direction to adjust the cutting width of the cold-rolled low-carbon steel strip according to cutting requirements; the second driving units can control the movement of the cutting blade in the Z-axis direction to control the cutting of the cold-rolled low-carbon steel strip.
[0011] As a further improvement to the above technical solution: the first driving unit includes: a second driving member, a lead screw, a slider, and two second connecting blocks. The driving end of the second driving member is connected to one end of the lead screw. The second driving member is connected to one of the second connecting blocks. The lead screw is threadedly connected to the slider. The cutting blade is rotatably connected to the slider through the bearing. The other end of the lead screw is rotatably connected to the other second connecting block. The telescopic end of the second driving unit is connected to the second connecting block. The two second driving units are arranged opposite to each other.
[0012] As a further improvement to the above technical solution: the second driving part includes: a third driving member and a third column, the third driving member is connected to the base plate, the third column is connected to the third driving member, and the telescopic end of the third column is connected to the second connecting block.
[0013] As a further improvement to the above technical solution: A fourth column is provided at both ends of the guide roller, the guide roller is rotatably connected to the fourth column, and the fourth column is connected to the base plate; a fifth column is provided at both ends of the separating roller, the separating roller is rotatably connected to the fifth column, and the fifth column is connected to the base plate. Thus, the guide roller can pull the cut cold-rolled low-carbon steel strip; the separating roller can separate the cut cold-rolled low-carbon steel strip.
[0014] As a further improvement to the above technical solution: the unwinding mechanism, the first winding mechanism, and the second winding mechanism have the same structure.
[0015] As a further improvement to the above technical solution: the first winding mechanism and the second winding mechanism are in opposite directions.
[0016] As a further improvement to the above technical solution, the cutting mechanism further includes a scale, the two ends of which are respectively connected to the two second connecting blocks. Thus, the scale allows control of the cutting blade's movement distance in the X-axis direction, ensuring that the cutting blade's position meets the cutting requirements.
[0017] The beneficial effects of this utility model are as follows:
[0018] The separating rollers can separate the cut cold-rolled low-carbon steel strips, ensuring that the cut strips are separated from each other and do not interfere with each other. The two parts of the cut cold-rolled low-carbon steel strips are then wound up by the first winding mechanism and the second winding mechanism, respectively, to improve the winding effect of the cut cold-rolled low-carbon steel strips.
[0019] This utility model also has the following advantages:
[0020] 1. This utility model can control the cutting blade to move in the X-axis direction through the first driving unit, so as to adjust the cutting width of the cold-rolled low-carbon steel strip according to the cutting requirements; and can control the cutting blade to move in the Z-axis direction through the second driving unit, so as to control the cutting of the cold-rolled low-carbon steel strip.

[0040] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0041] like Figures 1 to 7The diagram shows the preferred embodiment of this utility model. The cutting device for cold-rolled low-carbon steel strip in this embodiment includes: an unwinding mechanism 1, a cutting mechanism 2, a guide roller 3, a separating roller 4, a first winding mechanism 5, and a second winding mechanism 6 arranged sequentially along the moving direction of the cold-rolled low-carbon steel strip. The unwinding mechanism 1, the guide roller 3, and the second winding mechanism 6 are on the same horizontal line. The separating roller 4 is located below the guide roller 3, and the first winding mechanism 5 is located below the separating roller 4. After the cold-rolled low-carbon steel strip is cut by the cutting mechanism 2 and guided by the guide roller 3, a portion of the cold-rolled low-carbon steel strip passes through the separating roller 4 and is wound up by the first winding mechanism 5, while the other portion of the cold-rolled low-carbon steel strip is directly wound up by the second winding mechanism 6. Therefore, the separating roller 4 can separate the cut cold-rolled low-carbon steel strip, so that the cut cold-rolled low-carbon steel strips are separated from each other and do not interfere with each other. After cutting, the two parts of the cold-rolled low-carbon steel strip are wound up by the first winding mechanism 5 and the second winding mechanism 6 respectively, so as to improve the winding effect of the cut cold-rolled low-carbon steel strip.
[0042] In other words, if the cut cold-rolled low-carbon steel strips are not separated, they will overlap. This will affect both the subsequent coiling of the cold-rolled low-carbon steel strips and the cutting effect (i.e., the overlap of the cut cold-rolled low-carbon steel strips will affect the uncut cold-rolled low-carbon steel strips, thus affecting the cutting effect).
[0043] Specifically, the direction of movement is the Y-axis.
[0044] In this embodiment, the system also includes: a base plate 7, an unwinding mechanism 1, a cutting mechanism 2, a guide roller 3, a separating roller 4, a first winding mechanism 5, and a second winding mechanism 6, all of which are connected to the base plate 7.
[0045] In this embodiment, the unwinding mechanism 1 includes a first driving member 101 and an expansion and contraction shaft 102. The first driving member 101 is connected to the base plate 7 through a first connecting block 103, and the driving end of the first driving member 101 is connected to the expansion and contraction shaft 102.
[0046] For example, the first driving component 101 is a motor.
[0047] In this embodiment, the cutting mechanism 2 comprises a cutting blade 201, a first driving unit 202, and two second driving units 204. The cutting blade 201 is rotatably connected to the first driving unit 202 via a bearing 203. The first driving unit 202 is connected to the telescopic ends of the second driving units 204, and the second driving units 204 are connected to the base plate 7. The two second driving units 204 are arranged opposite to each other. The first driving unit 202 drives the cutting blade 201 to move along the X-axis, and the second driving units 204 drive the cutting blade 201 to move along the Z-axis. The first driving unit 202 includes a second driving member 2021, a lead screw 2022, a slider 2023, and two second connecting blocks 2024. The driving end of the second driving member 2021 is connected to one end of the lead screw 2022. The cutting mechanism 2 is connected to a second connecting block 2024, a lead screw 2022 is threadedly connected to a slider 2023, a cutting blade 201 is rotatably connected to a slider 2023 via a bearing 203, the other end of the lead screw 2022 is rotatably connected to another second connecting block 2024, and the telescopic end of the second driving part 204 is connected to the second connecting block 2024; the two second driving parts 204 are arranged opposite to each other; the second driving part 204 includes: a third driving member 2041 and a third column 2042, the third driving member 2041 is connected to the base plate 7, the third column 2042 is connected to the third driving member 2041, and the telescopic end of the third column 2042 is connected to the second connecting block 2024; the cutting mechanism 2 also includes: a scale 205, the two ends of the scale 205 are respectively connected to the two second connecting blocks 2024. Therefore, the first drive unit 202 can control the cutting blade 201 to move in the X-axis direction to adjust the cutting width of the cold-rolled low-carbon steel strip according to the cutting requirements; the second drive unit 204 can control the cutting blade 201 to move in the Z-axis direction to control the cutting of the cold-rolled low-carbon steel strip; and the scale 205 can control the moving distance of the cutting blade 201 in the X-axis direction to ensure that the position of the cutting blade 201 meets the cutting requirements.
[0048] Specifically, the second drive component 2021 uses an electric motor, and the third drive component 2041 uses a cylinder.
[0049] In this embodiment, both ends of the guide roller 3 are provided with a fourth column 301, and the guide roller 3 is rotatably connected to the fourth column 301. The fourth column 301 is connected to the base plate 7. Both ends of the separating roller 4 are provided with a fifth column 401, and the separating roller 4 is rotatably connected to the fifth column 401. The fifth column 401 is connected to the base plate 7. Thus, the guide roller 3 can pull the cut cold-rolled low-carbon steel strip; the separating roller 4 can separate the cut cold-rolled low-carbon steel strip.
[0050] In this embodiment, the unwinding mechanism 1, the first winding mechanism 5, and the second winding mechanism 6 have the same structure; the first winding mechanism 5 and the second winding mechanism 6 are in opposite directions. Specifically, the first winding mechanism 5 is used to wind up the cut cold-rolled low-carbon steel strip scrap, and the second winding mechanism 6 is used to wind up the cut cold-rolled low-carbon steel strip.
[0051] It should be noted that the opposite directions of the first winding mechanism 5 and the second winding mechanism 6 mean that the driving end of the first driving member 101 of the first winding mechanism 5 and the driving end of the first driving member 101 of the second winding mechanism 6 are oriented differently.
[0052] The cutting process of the cold-rolled low-carbon steel strip of this utility model is as follows: First, the cold-rolled low-carbon steel strip to be cut is installed on the unwinding mechanism 1 (i.e., installed on the expansion shaft 102 via the first winding machine), and the second winding machine and the third winding machine are respectively installed on the first winding mechanism 5 and the second winding mechanism 6; then, according to the cutting requirements of the cold-rolled low-carbon steel strip, the position of the cutting blade 201 is adjusted by the first driving part 202; then, the third driving part 2041 is controlled to shorten, so as to drive the cutting blade 201 to move downward until the cutting blade 201 makes contact with the cold-rolled low-carbon steel strip. The steel strip comes into contact (i.e., during cutting, the cutting blade 201 contacts the cold-rolled low-carbon steel strip; when not cutting, the cutting blade 201 does not contact the cold-rolled low-carbon steel strip); finally, the first drive unit 101 is activated, and the cutting blade 201 is used to cut the cold-rolled low-carbon steel strip. A portion of the cut cold-rolled low-carbon steel strip first passes through the separating roller 4, and then is wound up by the first winding mechanism 5 (i.e., the cut cold-rolled low-carbon steel strip scrap). The other portion of the cut cold-rolled low-carbon steel strip is directly wound up by the second winding mechanism 6 (i.e., the cut cold-rolled low-carbon steel strip).
[0053] In summary, this utility model can separate the cut cold-rolled low-carbon steel strip by using the separating roller 4, so that the cut cold-rolled low-carbon steel strips are separated from each other and do not interfere with each other. After cutting, the two parts of the cold-rolled low-carbon steel strip are wound up by the first winding mechanism 5 and the second winding mechanism 6 respectively, so as to improve the winding effect of the cut cold-rolled low-carbon steel strip.
[0054] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
