Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a portable metal cutting guide bracket. Background Technology

[0002] Metal cutting is a common process in industrial manufacturing and processing, used to divide metal materials into specific shapes and sizes according to design requirements. During the cutting operation, a cutting guide bracket is usually used to assist in the cutting operation, clamping the metal and pushing it to move continuously for cutting. When the cutting blade cuts the metal, it will create resistance to the continuous movement of the metal. As the pressure plate continuously pushes the metal, the opposing forces in the two directions of thrust and resistance may cause damage to the metal, which is not conducive to the smooth progress of the metal cutting operation.

[0003] To address the aforementioned issues, a portable metal cutting guide bracket has been developed. Utility Model Content

[0004] To overcome the disadvantages of the continuous resistance to the movement of metal during cutting by the cutting blade, and the potential damage to the metal caused by the opposing forces of thrust and resistance due to the continuous pushing of the metal by the pressure plate, which hinders the smooth operation of metal cutting, this utility model provides a portable metal cutting guide bracket.

[0005] The technical implementation scheme of this utility model is as follows: a portable metal cutting guide bracket, including a bracket, a handle connected to the bracket, a slider slidably connected to the bracket, two linear motors mounted on the slider, the output shafts of the linear motors being rotatably connected to the slider, rollers connected to the output shafts of the linear motors, rollers also rotatably connected to the left front and right rear of the slider, the rollers being slidably connected to the bracket, a lead screw rotatably connected to the left front of the slider, a first connecting plate threaded onto the lead screw, a connecting rod slidably connected to the first connecting plate, a pressure plate connected to the connecting rod, a pressure sensor mounted on the first connecting plate, the pressure sensor being in contact with the pressure plate, and reinforcement mechanisms provided on both the left and right sides of the bracket.

[0006] Furthermore, the reinforcement mechanism includes a second connecting plate. The lower left and right sides of the bracket are each connected to the second connecting plate by two bolts. A connecting tube is connected to the outer side of each second connecting plate. A suction cup is connected to the other end of each connecting tube. A silicone pad is connected to the lower part of each suction cup. A guide rod is slidably connected to each suction cup. A handle is rotatably connected to each guide rod. A spring is connected between each guide rod and the adjacent suction cup.

[0007] Furthermore, it also includes a chip removal mechanism, which includes a third connecting plate. The third connecting plate is slidably connected to the upper rear side of the bracket. An air duct is connected to the third connecting plate. A motor is installed on the left side, and a fan is connected to the output shaft of the motor.

[0008] Furthermore, the handle is an arc-shaped structure that conforms to the human finger.

[0009] Furthermore, the lead screw is equipped with a handle.

[0010] Furthermore, the lower part of the pressure plate is provided with an anti-slip pad.

[0011] By adopting the above technical solution, this utility model has the following advantages:

[0012] 1. This utility model incorporates a pressure sensor. When the cutting blade cuts metal, the metal experiences resistance. This resistance is transmitted to the pressure sensor through the metal and pressure plate. The pressure sensor automatically adjusts the speed of the linear motor, slowing down the movement speed of the roller, thereby reducing the rightward thrust on the metal and protecting it. At the same time, a reinforcement mechanism is used to further fix the bracket, preventing displacement of the bracket during metal cutting.

[0013] 2. This utility model is equipped with a chip removal mechanism that uses wind power to remove debris adhering to the metal surface, which helps to ensure the accuracy of metal cutting. Attached Figure Description

Detailed Implementation

[0021] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example 1

[0023] A portable metal cutting guide bracket, such as Figure 1 and Figure 2 As shown, the device includes a bracket 1, a handle 2 connected to the bracket 1, the handle 2 being an arc-shaped structure that conforms to the human finger, a slider 3 slidably connected to the bracket 1, two linear motors 5 mounted on the slider 3, the output shafts of the linear motors 5 being rotatably connected to the slider 3, and rollers 4 connected to the output shafts of the linear motors 5, the left front and right rear parts of the slider 3 also being rotatably connected to rollers 4, the rollers 4 being slidably connected to the bracket 1, a lead screw 6 rotatably connected to the front left side of the slider 3, the lead screw 6 having a handle, a first connecting plate 7 threadedly connected to the lead screw 6, a connecting rod 8 slidably connected to the first connecting plate 7, a pressure plate 9 connected to the connecting rod 8, an anti-slip pad at the bottom of the pressure plate 9, a pressure sensor 10 mounted on the first connecting plate 7, the pressure sensor being in contact with the pressure plate 9, and reinforcement mechanisms 11 provided on both the left and right sides of the bracket 1.

[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the reinforcement mechanism 11 includes a second connecting plate 111. The second connecting plate 111 is connected to the lower left and right sides of the bracket 1 by two bolts 112. The outer side of the second connecting plate 111 is connected to a connecting tube 113. The other end of the connecting tube 113 is connected to a suction cup 114. The lower part of the suction cup 114 is connected to a silicone pad 115. The suction cup 114 is slidably connected to a guide rod 116. The guide rod 116 is rotatably connected to a handle 117. The guide rod 116 and the adjacent suction cup 114 are connected to a spring 118.

[0025] It should be noted that metal cutting is a common process in industrial manufacturing and processing, used to divide metal materials into specific shapes and sizes according to design requirements. During metal cutting, a cutting guide bracket 1 is usually used to assist the cutting operation. First, the bracket 1 is placed in a suitable position on the operating table using the handle 2, so that the metal to be cut is located under the pressure plate 9. Then, the lead screw 6 is rotated, causing the first connecting plate 7 to move downwards, which in turn drives the connecting rod 8 and the pressure plate 9 to move downwards, thus pressing the pressure plate 9 firmly against the metal to be cut. The lower anti-slip pad increases the friction of the metal surface, providing an anti-slip effect. Then, the linear motor 5 is activated. The output shaft of the linear motor 5 rotates, causing the adjacent roller 4 to rotate, which in turn moves the slider 3 to the right. This causes the lead screw 6 and the first connecting plate 7 to move to the right. Since the lower part of the pressure plate 9 is pressing against the metal, the first connecting plate 7 slides to the right on the connecting rod 8, causing the pressure sensor 10 to move to the right until it contacts the left side of the pressure plate 9. As the slider 3, the first connecting plate 7, and the pressure sensor 10 push the pressure plate 9 to the right, the pressure plate... 9 pushes the metal to the right, thereby continuously pushing the metal to cut in the preset direction. When the cutting blade cuts the metal, it will create resistance to the metal's rightward movement. Since the pressure plate 9 continuously pushes the metal to the right, the opposing forces of the pushing force and resistance may cause damage to the metal. At this time, the resistance is transmitted to the pressure sensor 10 through the metal, pressure plate 9, etc. The pressure sensor 10 will automatically adjust the speed of the linear motor 5 and slow down the movement speed of the roller 4, thereby reducing the rightward pushing force on the metal and protecting it. To further enhance the overall stability of the device and prevent the bracket 1 from shaking during the cutting process, the reinforcement mechanism 11 can be used to improve the stability of the device. The silicone pad 115 is attached to the operating table, and the suction cup 114 is squeezed to expel the air between the silicone pad 115 and the operating table. Then, the handle 117 is flipped forward, causing the guide rod 116 to move upward and the spring 118 to be compressed. Under the action of atmospheric pressure, the silicone pad 115 will be tightly attached to the surface of the operating table, thereby providing auxiliary fixation for the bracket 1 and preventing the bracket 1 from shifting during the metal cutting process.

[0026] Example 2

[0027] Based on Example 1, such as Figure 1 and Figure 5 As shown, it also includes a chip removal mechanism 12, which includes a third connecting plate 121. The third connecting plate 121 is slidably connected to the upper rear side of the bracket 1. A duct 122 is connected to the third connecting plate 121. A motor 123 is installed on the left side. A fan 124 is connected to the output shaft of the motor 123.

[0028] It should be noted that metal shavings will be generated during the cutting process. These shavings may adhere to the metal surface and affect the accuracy of metal cutting. The fan 124 can be rotated by the motor 123, and the air duct 122 can be aligned with the location of the shavings to remove them by using air force, which helps to ensure the accuracy of metal cutting.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
