Description

Technical Field

[0001] This utility model relates to the field of CNC metal processing equipment technology, specifically a CNC steel strip cutting machine. Background Technology

[0002] Steel strip is widely used in the processing of hardware, automobiles, home appliances and many other industries. Traditional manual or semi-automatic cutting methods have problems such as low efficiency, insufficient precision, operation safety hazards, easy cracking of cuts and many burrs. With the development of CNC technology and automation control, CNC steel strip cutting machines that can achieve precise cutting and efficient operation have been developed and applied to solve the pain points of traditional processes.

[0003] After searching, the existing technology (application number: CN202320580255.8) describes that "the positioning ring is driven to move along the guide rail by a bidirectional screw to realize the positioning of the steel strip width, and the steel strip is conveyed with a single set of transmission rollers. The cutting operation is completed by a fixed cutter, and the chip discharge port at the bottom is set to collect the cutting chips."

[0004] This utility model only realizes the basic functions of steel strip positioning and cutting, without integrating burr removal, steel strip flattening and cutting buffer structure, and the single drive roller conveyor is prone to steel strip deviation, and the cutter is prone to wear due to the lack of buffer design. Therefore, it needs to be improved. Utility Model Content

[0013] As a further description of the above technical solution:

[0014] The handwheel is located in a through hole on one side of the housing and is fixedly connected to the double-acting screw. There are two sets of adjusting blocks with threaded holes at the bottom. Both sets are threadedly connected to the double-acting screw and slidably connected to the housing. The guide wheel is located on the adjusting block and is rotatably connected to the adjusting block to prevent the steel strip from shifting.

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, this embodiment provides a CNC steel strip cutting machine, comprising: a chamber 1, including a housing 101, with a through hole on one side of the housing 101, a sliding groove at the feed inlet, and a limit groove inside the discharge outlet of the housing 101; a transmission structure 2, arranged inside the chamber 1, including a transmission roller 201, with two sets of transmission rollers 201 rotatably connected to the housing 101, and also including a cutting mechanism; and a power structure 3, including a motor 301, with the motor 301 arranged on one side of the housing 101.

[0033] In this embodiment, the cabin structure and the transmission structure constitute a CNC steel strip cutting machine according to this application.

[0034] It should also be noted that the cutting machine in this application can be a steel strip cutting machine, an aluminum strip cutting machine, etc. Figure 1 In this embodiment, a steel strip cutting machine is used as an example for description. Of course, other types of cutting machines can also adopt a similar structure, which will not be described in detail below.

[0035] Understandable Figure 1 The steel strip cutting machine is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, steel strip cutting machines can also include, compared to... Figure 1 More or fewer parts.

[0036] It should also be understood that the motors were all purchased from the market and are common knowledge in this field. They are only used and not modified, so the control methods and circuit connections will not be described in detail.

[0037] In addition, in this embodiment, the cabin 1 provides the installation foundation, the transmission roller 201 supports the steel belt conveying, and the power structure 3 provides power, thus realizing the basic support for steel belt conveying and cutting.

[0038] Specifically, the chamber 1 includes: an operating table 102, arranged on the top of the box 101; positioning holes 103, which are opened at the feed inlet sliding groove on one side of the box 101 and are arranged in multiple sets; positioning sliders 105, which are arranged in two sets, with a rotating wheel on the top, which is slidably connected to the sliding groove opened in the box 101, and a threaded hole on the bottom for positioning steel strips of different widths; and bolts 104, which are threadedly connected to the through hole opened in the box 101 and the threaded hole opened in the positioning slider 105, for limiting the position of the positioning slider 105 in the box 101.

[0039] In this embodiment, the bolt 104 passes through the positioning hole 103 and engages with the threaded hole of the positioning slider 105. By unscrewing the bolt 104, the positioning slider 105 can move along the sliding groove to adapt to steel strips of different widths and reduce friction during steel strip conveying.

[0040] Specifically, the chamber 1 also includes: a discharge port 106 located at the bottom of the chamber 101 for discharging debris; and a discharge chute 107 located at the discharge port on one side of the chamber 101.

[0041] As a preferred implementation, the burrs and debris generated during cutting are discharged through the discharge port 106, and the cut steel strip is discharged through the discharge chute 107 made of stainless steel, keeping the inside of the equipment clean and achieving orderly discharge of the steel strip.

[0042] Example 2:

[0043] Based on Example 1, in order to further improve stability, a transmission structure 2 is arranged inside the cabin 1;

[0044] Specifically, the transmission structure 2 includes: two sets of gears 202, which are arranged on one side of the two sets of transmission rollers 201 and mesh with each other to synchronize the rotation of the two sets of transmission rollers 201; and a bidirectional screw 204, which is arranged inside the housing 101 and rotatably connected to the housing 101.

[0045] In this embodiment, the two sets of gears 202 mesh with each other and synchronously drive the two sets of transmission rollers 201 to rotate; the bidirectional screw 204 rotates in conjunction with the housing 101 to ensure that the transmission rollers 201 rotate at the same speed, providing an installation carrier for the subsequent adjustment structure.

[0046] Specifically, the transmission structure 2 further includes: a handwheel 203 arranged in a through hole on one side of the housing 101 and fixedly connected to the bidirectional screw 204; two sets of adjusting blocks 205 are provided, each with a threaded hole at the bottom, both sets being threadedly connected to the bidirectional screw 204 and slidably connected to the housing 101; a guide wheel 206 is arranged on the adjusting block 205 and rotatably connected to the adjusting block 205 to prevent the steel strip from shifting; and a deburring knife 207 is arranged on one side of the adjusting block 205 to clean the burrs on the edge of the steel strip.

[0047] With this configuration, the cast iron handwheel 203 drives the bidirectional screw 204 to rotate, which in turn drives the two sets of adjusting blocks 205, made of aluminum alloy, to move symmetrically. The polyurethane guide wheel 206 conforms to the edge of the steel belt for guidance, and the carbide blade 207, made of hard alloy, contacts the edge of the steel belt to clean burrs, preventing the steel belt from shifting during transport and simultaneously removing burrs from the edge of the steel belt.

[0048] Specifically, the cutting mechanism includes: a pressure roller 208 arranged inside the housing 101 for straightening the steel strip; a cutting blade 209 arranged inside the housing 101, with a hydraulic component on the top of the cutting blade 209 for cutting the steel strip; a blade buffer groove 210 arranged in a limiting groove inside the housing 101 for buffering the cutting blade 209; and a spring 211 connected at one end to the housing 101 and at the other end to the blade buffer groove 210 for resetting the blade buffer groove 210.

[0049] The pressure roller 208 flattens the steel strip, the cutting blade 209 cuts the steel strip through hydraulic components, the blade buffer groove 210 bears the cutting impact force, and the spring 211 returns the blade buffer groove 210 to its original position after being stretched, thus ensuring the flatness of the steel strip cutting, extending the service life of the cutting blade 209, and realizing the automatic reset of the buffer structure.

[0050] Specifically, the output end of motor 301 is connected to a set of transmission rollers 201.

[0051] In this embodiment, the motor 301 starts and outputs torque, which is transmitted to the transmission roller 201 through the connection structure, providing a stable and continuous power output for the transmission structure 2.

[0052] In actual use, first place the housing 101 on the working ground, then unscrew the bolt 104 from the through hole in the housing 101 and the threaded hole in the positioning slider 105, allowing the two sets of positioning sliders 105 to slide inside the housing 101. Adjust the two sets of positioning sliders 105 to fit against the steel strip, so that the edge of the steel strip is placed in the rotating wheel set in the positioning slider 105. Then, screw the bolt 104 back into the through hole in the housing 101 and the threaded hole in the positioning slider 105 to position the steel strip. Then start the device; the motor 301 starts and drives one set of transmission rollers 201 to rotate. Through the meshing of two sets of gears 202, the other set of transmission rollers 201 rotate together. The steel strip enters the device, and then the handwheel 203 is turned to drive the double screw 204 to move the two sets of adjusting blocks 205 inwards simultaneously until the burr cutter 207 is in contact with the edge of the steel strip to clean the burrs on the edge of the steel strip. The cut-off debris is discharged from the discharge port 106. Then the steel strip is compressed again by the pressure roller 208 to make the steel strip flat. Then it is cut by the cutting blade 209. When the cutting blade 209 cuts, it impacts the blade buffer groove 210. The spring 211 is deformed by the impact and squeeze, so that the cutting blade 209 is buffered and protected. When there is no impact, the spring 211 automatically rebounds and pushes the blade buffer groove 210 to reset. The cut steel strip is discharged from the discharge chute 107.

[0053] This device integrates core functions such as width adaptive adjustment, edge burr removal, steel strip flattening, and buffer cutting. It is easy to adjust and can quickly adapt to different specifications of strip materials. Simultaneous burr removal reduces subsequent processes, the flattening structure ensures the flatness of the cut, and the buffer design extends the tool life. It also provides stable feeding and precise cutting, and can be adapted to a variety of medium and thin metal strip materials, effectively improving processing efficiency and finished product quality.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
