DETAILED DESCRIPTION

[0026] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that 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 description are illustrative in nature and are not intended to limit the scope of the claims.

[0027] like Figure 1 and Figure 2 As shown, the light steel keel cutting and shaping machine includes a mounting platform 1, on which a profile mold 2 is fixedly mounted, a C-shaped channel 3 for the light steel keel to pass through is horizontally provided in the middle of the profile mold 2, a vertically arranged tool channel 4 is provided at the top of the profile mold 2, and horizontally arranged shaping channels 5 are provided at the left and right ends of the profile mold 2; a tool cutting device that can slide back and forth vertically is installed on the mounting platform 1, a power drive device is provided between the mounting platform 1 and the tool cutting device, a cutting knife 6 is fixedly mounted on the top of the tool cutting device, and the bottom cutting edge of the cutting knife 6 is inserted into the tool channel 4, and shaping sliders 7 are respectively installed on the left and right sides of the profile mold 2, and the inner end of the shaping slider 7 is inserted into the shaping channel 5, a horizontal limit device is provided between the mounting platform 1 and the outer end of the shaping slider 7, and the tool cutting device is also provided with a slider guide device that cooperates with the outer end of the shaping slider 7. When not cutting, the C-shaped light steel keel is transported forward through the C-shaped channel 3. At this time, the tool cutting device is at the top dead center. The bottom cutting edge of the cutting knife 6 is located in the tool channel 4 but has a distance from the top surface of the light steel keel. The inner ends of the shaping sliders 7 on both sides are located in the shaping channel 5 but have a distance from the side end surfaces of the light steel keel. Figure 3When cutting is required, the light steel keel stops moving, and the power drive device controls the knife cutting device to slide downward, driving the cutting knife 6 to move downward. During the downward sliding process of the knife cutting device, the shaping slider 7 slides horizontally along the horizontal limit device toward one side of the light steel keel, and the inner end of the shaping slider 7 gradually approaches the side surface of the light steel keel. When the shaping slider 7 completely contacts the side surface of the light steel keel, the cutting knife 6 starts to cut the light steel keel. During the entire cutting process, the shaping slider 7 remains stationary, and the inner end always squeezes and supports the side surface of the light steel keel to avoid deformation during cutting and achieve the purpose of shaping. The state during the cutting process is shown in FIG. Figure 4 When the cutting is completed, the power drive device controls the tool cutting device to slide upward, driving the cutting knife 6 to move upward. When the cutting knife 6 is completely retracted, as the cutting knife 6 continues to move upward, the shaping slider 7 is driven to slide horizontally toward the side away from the light steel keel. At this time, the two ends of the light steel keel are no longer squeezed and continue to be transported forward.

[0028] See also Figure 1 and Figure 2 The tool cutting device includes a tool mounting upper seat 8 and a tool mounting lower seat 9, which are respectively located above and below the mounting platform 1. A mounting seat guide column 10 is connected between the tool mounting upper seat 8 and the tool mounting lower seat 9. The mounting seat guide column 10 is vertically slidably mounted on the mounting platform 1. The cutting knife 6 is fixedly mounted on the tool mounting upper seat 8. The power drive device is connected between the mounting platform 1 and the tool mounting lower seat 9. The mounting platform 1 is fixed on the production line and serves as the mounting base of this mechanism. Four guide column holes are provided on the surface of the mounting platform 1. The four mounting seat guide columns 10 pass through the guide column holes respectively. The tool mounting upper seat 8 is fixed to the top of the four mounting seat guide columns 10, and the tool mounting lower seat 9 is fixed to the bottom of the four mounting seat guide columns 10. The power drive device is a cylinder 18. The cylinder body end of the cylinder 18 is fixedly mounted on the mounting platform 1, and the cylinder rod end of the cylinder 18 is fixedly mounted on the tool mounting lower seat 9.

[0029] See also Figure 5The slider guide device includes a shaping guide vertical plate 11 fixedly mounted on the top of the tool cutting device. The top of the shaping guide vertical plate 11 is fixed to the tool mounting upper seat 8. The surface of the mounting platform 1 is provided with rectangular guide holes on both sides of the profile mold 2. The lower portion of the shaping guide vertical plate 11 slides through the rectangular guide holes of the mounting platform 1. The shaping guide vertical plate 11 is provided with a shaping guide groove 12 for driving the shaping slider 7 to slide horizontally. The outer end of the shaping slider 7 is mounted with a guide bearing 14 via a connecting shaft 13. The guide bearing 14 is slidably mounted in the shaping guide groove 12. In this embodiment, four shaping guide vertical plates 11 are provided. Two shaping guide vertical plates 11 form a group and are located on both sides of the profile mold 2. The shaping guide vertical plates 11 of the same group are arranged front and back along the production line direction, clamping the horizontal limit device and shaping slider 7 on the same side in the middle. The shaping slider 7 is connected to the connecting shaft 13 via a retaining ring, and the guide bearing 14 is fixed at both ends of the shaping slider 7, and the guide bearing 14 is limitedly installed in the shaping guide groove 12, and the outer periphery of the guide bearing 14 corresponds to the width of the shaping guide groove 12.

[0030] See also Figure 5 The shaping guide groove 12 includes a vertical shaping guide groove 12, the bottom end of which is inclined outward and downward to form a camber release guide groove. When the guide bearing 14 is in the camber release guide groove, the inner end of the shaping slider 7 is spaced apart from the light steel keel and does not contact it. When the guide bearing 14 is in the vertical shaping guide groove 12, the inner end of the shaping slider 7 contacts the inner surface of the light steel keel. During the cutting process, when the cutting tool device moves downward as a whole, it drives the shaping guide vertical plate 11 downward. The downward movement of the camber release guide groove pushes the guide bearing 14 inward. When the guide bearing 14 contacts the vertical shaping guide groove 12, it no longer slides inward.

[0031] See also Figure 6 and Figure 7The horizontal limit device includes a fixed limit frame 15 fixedly mounted on the mounting platform 1. The inner end of the fixed limit frame 15 is provided with a horizontal limit guide groove 16. The inner end of the shaping slider 7 slides through the horizontal limit guide groove 16 and extends into the shaping channel 5. The fixed limit frame 15 is provided with a slider space 17 to accommodate the connecting shaft 13. During installation, the connecting shaft 13 on the outer end of the shaping slider 7 passes through the slider space 17 and extends into the shaping guide groove 12 for installation of the guide bearing 14. The inner end of the shaping slider 7 is adapted to the horizontal limit guide groove 16 to limit the sliding of the shaping guide groove 12 to only horizontal direction. In this embodiment, the fixed limit frame 15 is located between the front and rear shaping guide vertical plates 11. The fixed limit frame 15 is formed by the U-shaped plate and the vertical plate connected to form a rectangle, and the two cooperate to limit the installation of the shaping slider 7.

[0032] The shaping slider 7 includes a slider mounting portion 7a provided at the outer end and a slider shaping portion 7b provided at the inner end. The inner end of the slider shaping portion 7b is provided with a shaping surface 7c adapted to the side surface shape of the light steel keel. The interior of the slider shaping portion 7b is also provided with a tool avoidance channel 7d corresponding to the tool channel 4 for the cutting knife 6 to pass through. A slider mounting hole 7e is provided on the slider mounting portion 7a. The slider mounting hole 7e is limitedly connected to the connecting shaft 13 by a retaining ring. The slider mounting portion 7a is limited in the slider space 17.

[0033] See also Figure 8 and Figure 9 The profile mold 2 is composed of a plurality of mold plates, and the shaping channel 5 is adapted to the slider mounting portion 7a.

[0034] The working principle of this embodiment is:

[0035] When not cutting, the C-shaped light steel keel is transported forward through the C-shaped channel 3. At this time, the tool cutting device is at the top dead center. The bottom cutting edge of the cutting knife 6 is located in the tool channel 4 but has a distance from the top surface of the light steel keel. The inner ends of the shaping sliders 7 on both sides are located in the shaping channel 5 but have a distance from the side end surfaces of the light steel keel. Figure 3 ;

[0036] When cutting is required, the light steel keel stops moving, and then the power cylinder 18 extends, the tool mounting upper seat 8, the tool mounting lower seat 9, the mounting seat guide column 10, and the shaping guide vertical plate 11 move downward, driving the cutting knife 6 to move downward. During the downward sliding of the shaping guide vertical plate 11, the guide bearing 14 slides inward under the thrust of the outward release guide groove, driving the shaping slider 7 to slide horizontally inward along the horizontal limit guide groove 16 and the shaping channel 5, close to the side surface of the light steel keel. As the shaping guide vertical plate 11 continues to move downward, the vertical shaping guide groove 12 contacts the guide bearing 14. At this time, the shaping surface 7c of the inner end of the shaping slider 7 completely contacts the side surface of the light steel keel. At this time, as the power cylinder 18 continues to extend, the cutting knife 6 begins to cut the light steel keel. During the entire cutting process, the shaping slider 7 remains stationary, and the inner end shaping surface 7c always squeezes and supports the side surface of the light steel keel to avoid deformation during cutting and achieve the shaping purpose. The state during the cutting process is shown in FIG. Figure 4 Since the shaping surface 7c completely corresponds to the shape of the side surface of the light steel keel, the light steel keel is supported to prevent the opening from expanding when cutting;

[0037] After the cutting is completed, the power cylinder 18 retracts, controlling the tool mounting upper seat 8, the tool mounting lower seat 9, the mounting seat guide column 10, and the shaping guide vertical plate 11 to move downward and slide upward, driving the cutting knife 6 to move upward. When the cutting knife 6 is completely retracted, as the cutting knife 6 continues to move upward, the outward-inclined release guide groove pushes the guide bearing 14 to slide outward, pushing the shaping slider 7 to slide horizontally toward the side away from the light steel keel. At this time, the two ends of the light steel keel are no longer squeezed and can continue to be transported forward.
