DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0020] like Figures 1 to 4 As shown, the square tube edge cutting tool is used to form an incision on the edge of the square tube 5. Specifically, it includes an incision platform 1, which is used to support related components and incision operations. A cutting pressure arm 2 is rotatably mounted on the incision platform 1, and a pressure arm return spring 3 is connected between the bottom of the incision pressure arm 2 and the incision platform 1. A cutting knife body 4 is also fixedly mounted on the bottom of the incision pressure arm 2 away from the end of the incision pressure arm 2 that is rotatably mounted. When in use, the incision pressure arm 2 is pressed down with the help of a power device such as a press and its pressure head, a driving cylinder, etc. that is located just above the incision pressure arm 2 and can move up and down, until the incision knife body 4 penetrates the square tube 5 to form an incision on the square tube 5. After the incision is completed and the power device is returned, the pressure arm return spring 3 automatically returns the incision pressure arm 2 and synchronously moves the incision knife body 4 out of the formed incision, so as to facilitate the removal of the square tube 5 that has completed the incision.

[0021] The incision pressure arm 2 of this embodiment includes a connecting portion 21 that is rotatably assembled with the incision platform 1, and the connecting portion 21 is set to a cylindrical structure. Two mounting ears 6 are arranged on the incision platform 1, and the connecting portion 21 is arranged between the two mounting ears 6 through the cooperation and rotation of the rotating shaft. The end of the connecting portion 21 is fixedly connected with a pressing portion 22, and the pressing portion 22 is provided with two pressing avoidance surfaces 23 arranged in a V shape. When the incision operation is implemented, the entire incision pressure arm 2 rotates downward until the two pressing avoidance surfaces 23 contact the two inner walls of the square tube 5, that is, the incision is completed, so that unnecessary extrusion is not caused to the inner wall of the square tube 5, which can play a certain protective role. The bottom ends of the two pressing avoidance surfaces 23 are connected by a mounting plane 24, and the incision blade 4 and the pressure arm return spring 3 are respectively connected to the mounting plane 24, which is convenient for the installation of the incision blade 4 and the pressure arm return spring 3, and helps to ensure the firmness of the installation of both. A pressure plane 25 is provided at the top of the pressing portion 22 for contacting the power device to bear the downward pressure of the power device and make the force uniform. An inclined cutting pressure surface 41 is provided at the bottom of the cutting blade 4 to help quickly form a cut on the square tube 5, thereby ensuring the efficiency of the cutting operation.

[0022] The cutting platform 1 is also fixedly mounted with a square tube positioning device, and the end of the cutting pressure arm 2 and the cutting blade body 4 are respectively arranged directly above the square tube positioning device. When in use, the square tube 5 is first placed on the square tube positioning device, and its end portion is partially sleeved on the outside of the cutting pressure arm 2, that is, the cutting blade body 4 is extended into the square tube 5, so that the cutting blade body 4 can form an incision on the square tube 5 by pressing down the power device.

[0023] Specifically, the square tube positioning device includes a square tube positioning platform 7, and the top of the square tube positioning platform 7 is provided with a square tube positioning groove 8 arranged in a V shape. After the square tube 5 is in place, its two adjacent side surfaces are respectively attached to the two groove walls of the square tube positioning groove 8. The square tube positioning groove 8 is used to support and limit the square tube 5 when the cutting action is implemented, so that it will contact the square tube positioning groove 8 more closely under the action of pressure, so that the square tube 5 is more fixed. The bottom of the square tube positioning groove 8 is connected to a knife body avoidance groove 9, and the cutting knife body 4 is located directly above the knife body avoidance groove 9. When cutting on the edge of the square tube 5, the square tube positioning groove 8 not only avoids the descending cutting knife body 4, but also avoids the pipe material that is turned outward by the cutting, so that the cutting operation is smoother. Since the cutting knife body 4 has a certain width and thickness, the end face of the knife body avoidance groove 9 is a rectangular structure so as to fully accommodate the descending cutting knife body 4.

[0024] like Figure 5 As shown, two square tube positioning stop arms 10 are relatively arranged on the square tube positioning platform 7, and the square tube positioning stop arms 10 are arranged on both sides of the cutting pressure arm 2. The square tube positioning stop arms 10 are arranged as an inverted L-shaped structure. After the end of the square tube 5 is placed in the square tube positioning groove 8, it is pushed toward the direction of the pressure arm return spring 3 until its end abuts against the two square tube positioning stop arms 10. When performing the cutting operation, the operator pushes the rear end of the square tube 5 forward and with the help of the blocking of the square tube positioning stop arms 10, the square tube 5 can be firmly limited in the square tube positioning groove 8, so that it will not move or shake during the entire cutting operation, so that the fixing effect of the square tube 5 is better.

[0025] like Figure 6 As shown, the incision formed by the incision cutter body 4 on the edge of the square tube 5 using this embodiment has a smooth and flat edge.

[0026] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
