Description

Technical Field

[0001] This utility model relates to the field of metal profiled sheet processing technology, specifically a protective structure for a metal profiled sheet cutting device. Background Technology

[0002] In the field of metal forming sheet processing technology, cutting is a crucial step.

[0003] The inventors discovered that at least the following problems remain unresolved in existing technologies: during the cutting process, metal forming sheets often generate a large amount of debris and sparks, which can pose a safety threat to operators. Furthermore, the metal forming sheet needs to remain stable during cutting to ensure accuracy and efficiency. However, traditional cutting devices are cumbersome to operate when fixing the metal forming sheet, which can easily affect the progress of the cutting operation.

[0004] Therefore, we propose a protective structure for a metal profiled sheet cutting device, which can solve the problems of debris splashing and the inconvenience of fixing the metal profiled sheet. Utility Model Content

[0005] The purpose of this utility model is to provide a protective structure for a metal profiled sheet cutting device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for a metal profiled sheet cutting device, including a cutting table, a mounting plate horizontally arranged above the cutting table, a bracket fixedly connected to the middle of the bottom side of the mounting plate, an electric cutting disc rotatably connected to the inner side of the bracket, and a transparent protective frame fixedly connected to the bottom side of the mounting plate; a protective mechanism for protection during metal profiled sheet cutting, the protective mechanism including an electro-hydraulic push rod, the telescopic end of the electro-hydraulic push rod being fixedly connected to the middle of the upper surface of the mounting plate, and the protective frame being movably connected to the cutting table; a fixing mechanism for automatic fixing during metal profiled sheet cutting, the fixing mechanism including a pressure plate, limit sleeves vertically fixedly installed on both sides of the lower surface of the mounting plate, a spring being provided between the limit sleeves and the pressure plate, and a through groove being formed in the middle of the upper surface of the pressure plate.

[0007] As an optional solution to the technical solution of this application, limit rods are vertically fixedly installed on both sides of the upper surface of the pressure plate, and the limit sleeve is slidably connected to the limit rods.

[0008] As an optional solution to the technical solution of this application, the spring is sleeved on the outside of the limiting rod, and the size of the limiting sleeve matches that of the limiting rod.

[0009] As an optional solution to the technical solution of this application, a fixing frame is vertically welded to the rear end of the upper surface of the cutting table, and the electro-hydraulic push rod is fixedly connected to the middle of the upper surface of the fixing frame.

[0010] As an optional solution to the technical solution of this application, a cutting groove is provided through the middle of the upper surface of the cutting table, the through groove corresponds to the cutting groove, and the size of the electric cutting disc matches that of the through groove and the cutting groove.

[0011] As an optional solution to the technical solution of this application, the pressure plate is placed horizontally inside the protective frame, and the protective frame is inverted U-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By controlling the operation of the electro-hydraulic push rod, the electric cutting disc rotating on the bottom side of the mounting plate can be pushed downward. Through the combination of the limiting rod, the limiting sleeve and the spring, the spring force can push the pressure plate to squeeze and fix the metal forming plate on the surface of the cutting table, which is convenient and quick. As the mounting plate continues to move downward, the electric cutting disc can pass through the through slot to cut the metal forming plate fixed on the bottom side of the pressure plate. At the same time, the mounting plate can push the transparent protective cover to be placed on the upper end of the cutting table, thereby automatically protecting the metal forming plate during the cutting process and preventing debris from flying.

[0017] Please see Figures 1-2This utility model provides a technical solution: a protective structure for a metal profiled sheet cutting device, including a cutting table 1, a mounting plate 11 horizontally arranged above the cutting table 1, a bracket 12 fixedly connected to the middle of the bottom side of the mounting plate 11, an electric cutting disc 13 rotatably connected to the inner side of the bracket 12, and a transparent protective frame 14 fixedly connected to the bottom side of the mounting plate 11; a protective mechanism for protection during metal profiled sheet cutting, the protective mechanism including an electro-hydraulic push rod 16, the telescopic end of the electro-hydraulic push rod 16 fixedly connected to the middle of the upper surface of the mounting plate 11, a fixed frame 15 vertically welded to the rear end of the upper surface of the cutting table 1, the electro-hydraulic push rod 16 fixedly connected to the middle of the upper surface of the fixed frame 15, and the protective frame 14 movably connected to the cutting table 1, the protective frame 14 being inverted U-shaped.

[0018] In this technical solution, the electro-hydraulic actuator 16 is controlled by a corresponding controller to move the mounting plate 11 up and down, which facilitates the adjustment of the position of the electric cutting disc 13 on the bottom side of the mounting plate 11. A transparent protective frame 14 is fixedly connected to the bottom side of the mounting plate 11. When the mounting plate 11 moves the electric cutting disc 13 down to cut the metal profiled sheet on the surface of the cutting table 1, the mounting plate 11 can push the protective frame 14 to cover the upper end of the cutting table 1, thereby automatically protecting the metal profiled sheet during the cutting process and preventing debris from flying.

[0019] In this embodiment, the fixing mechanism is used for automatic fixing during the cutting of metal profiled sheets. The fixing mechanism includes a pressure plate 2, which is horizontally placed inside the protective frame 14. Limit sleeves 22 are vertically fixed on both sides of the lower surface of the mounting plate 11. A spring 23 is provided between the limit sleeve 22 and the pressure plate 2. The size of the limit sleeve 22 matches that of the limit rod 21. A through groove 25 is provided in the middle of the upper surface of the pressure plate 2. A cutting groove 24 is provided in the middle of the upper surface of the cutting table 1. The through groove 25 corresponds to the cutting groove 24, and the size of the electric cutting disc 13 matches that of the through groove 25 and the cutting groove 24.

[0020] In this technical solution, when the electro-hydraulic actuator 16 pushes the electric cutting disc 13 on the bottom side of the mounting plate 11 downward to cut the metal profile on the surface of the cutting table 1, the pressure plate 2 on the bottom side of the mounting plate 11 first adheres to the upper surface of the metal profile. A spring 23 is provided between the mounting plate 11 and the pressure plate 2. Through the elastic force of the spring 23, the pressure plate 2 can be pushed to press and fix the metal profile on the surface of the cutting table 1. As the mounting plate 11 continues to move downward, the rotating electric cutting disc 13 can pass through the through groove 25 and the cutting groove 24 to cut the metal profile fixed on the bottom side of the pressure plate 2. Conversely, when the electro-hydraulic actuator 16 drives the electric cutting disc 13 on the bottom side of the mounting plate 11 to move upward and reset, it can drive the pressure plate 2 to move upward and separate from the cut metal profile, making it convenient for the staff to collect the cut metal profile.

[0021] In this embodiment, limit rods 21 are vertically fixedly installed on both sides of the upper surface of the pressure plate 2, the limit sleeve 22 is slidably connected to the limit rods 21, and the spring 23 is sleeved on the outside of the limit rods 21.

[0022] In this technical solution, the slidable connection between the limiting rod 21 and the limiting sleeve 22 can improve the stability of the pressure plate 2 during use. The spring 23 is sleeved on the outside of the limiting rod 21, and the limiting rod 21 can limit the spring 23 to avoid tilting during the compression and extension of the spring 23, which would affect the performance.

[0023] When using the protective structure of a metal profiled sheet cutting device, the metal profiled sheet to be cut is placed on the upper surface of the cutting table 1. Then, the cutting position of the metal profiled sheet is adjusted to align with the electric cutting disc 13. The electro-hydraulic push rod 16 is controlled by the corresponding controller to push the electric cutting disc 13 on the bottom side of the mounting plate 11 downward. The pressure plate 2 on the bottom side of the mounting plate 11 first adheres to the upper surface of the metal profiled sheet and is slidably connected to the limiting sleeve 22 through the limiting rod 21. A spring 23 is sleeved on the outer side of the limiting rod 21. The elastic force of the spring 23 can push the pressure plate 2 to press and fix the metal profiled sheet on the surface of the cutting table 1. As the mounting plate 11 continues to move downward, the rotating electric cutting disc 13 can penetrate the through groove 25 and the cutting disc. The cutting groove 24 cuts the metal forming plate fixed to the bottom side of the pressure plate 2. A transparent protective frame 14 is fixedly connected to the bottom side of the mounting plate 11. When the mounting plate 11 drives the electric cutting disc 13 to move downward to cut the metal forming plate on the surface of the cutting table 1, the mounting plate 11 can push the protective frame 14 to cover the upper end of the cutting table 1, thereby automatically protecting the metal forming plate during the cutting process and preventing debris from flying. Conversely, when the electro-hydraulic push rod 16 drives the electric cutting disc 13 on the bottom side of the mounting plate 11 to move upward and reset, it can drive the pressure plate 2 to move upward and separate from the cut metal forming plate. At the same time, the mounting plate 11 drives the protective frame 14 to move upward and reset, making it convenient for the staff to collect the cut metal forming plate.
