[0015] The present invention provides a ground angle steel cutting device for preventing deformation of profile processing, which has the following beneficial effects:

[0016] 1. The ground angle steel cutting equipment for preventing deformation of profile processing uses a micro motor to drive the main gear to mesh with the double gear set to rotate the right-angled knife body stored in the storage cavity around the shaft pin in the middle of the double gear set at a flat angle, so that the right-angled knife body is wrapped and shielded on the cutting disk through an arc-shaped blade groove, specifically wrapped and shielded in a semicircular ring shape directly below the cutting disk. The right-angled knife body and the cutting disk form a rectangular knife plate structure with a semicircular bulge in the middle. The rectangular knife plate assembled by the two is used to expand the cutting cross section of the cutting disk, and the angle steel is cut horizontally in a short time to supplement the edges of the angle steel that have not been cut cleanly, thereby eliminating the cutting dead angle.

[0017] 2. The ground angle steel cutting equipment for anti-deformation processing of profiles provides a second cutting operation form for cutting angle steels: one is the rotation cutting provided by the cutting disc, and the other is the chopping type cutting composed of a cutting disc combined with a right-angled blade body with a larger area and a longer horizontal cutting surface. It can be adaptively selected according to the cutting conditions of the angle steel and the cutting requirements.

[0018] 3. The grounded angle steel cutting equipment for anti-deformation processing of profiles can use the cutting disc and the right-angled blade body alternately to solve the problem of local blade curling or damage due to excessive fatigue caused by the cutting disc or the right-angled blade body under continuous high-intensity cutting operations of the angle steel; at the same time, the cutting disc can also be assembled and stored on the right-angled blade body through the arc-shaped blade groove, which plays a role in protecting the cutting disc blade and preventing foreign matter from directly contaminating the cutting disc blade and affecting the cutting accuracy of the cutting disc.

[0019] Fourth, the grounded angle steel cutting equipment for anti-deformation processing of profiles is assembled under the cutting disc by rotating the right-angled knife body and engaging with the cutting disc. After the first motor is activated to drive the right-angled knife body to cut into the inner side of the vertical plate, the machine is immediately stopped. The right-angled knife body can be stored inside the vertical plate, and the processing cutting disc can be stored and protected inside the arc-shaped blade groove. In this way, two sets of different knives can be stored and protected at the same time, and the potential injury of the above two sets of knives during shutdown can be avoided, thereby improving the safe use performance of the cutting equipment and the diversity of cutting functions.

[0020] 5. The grounded angle steel cutting equipment for preventing deformation of the profile processing adjusts the angle between the first angle piece and the second angle piece with the help of the top plate by the third electric push rod, and the top block and the corner block are pulled down when the first electric push rod is retracted to limit the fit of the top of the angle steel. This enables the positioning component to not only fit, clamp and limit the points on the front and rear sides of the cut part of the angle steel, but also avoid deformation and displacement of the cut part, effectively improving the cutting accuracy and smoothness of the angle steel, while also ensuring the flatness and consistency of the cut surface of the angle steel.

[0021] 6. The grounded angle steel cutting equipment for anti-deformation processing of profiles can match the existing conveying device on the cutting machine with the forward and backward sliding movement of the long rod on the square plate frame through the electric slide, and can move the conveying direction of the angle steel in the opposite direction, thereby speeding up the guiding progress of the angle steel on the cutting device, and can also independently adjust the specific cutting position of the angle steel; by activating four servo motors at the same time, the crossbeam can be raised and lowered in the vertical guiding position of the screw rod through the ball spline under the guidance of the screw rod, and the overall cutting operation height of the electric slide can be adjusted independently to adapt to the conveying of the angle steel by conveying devices of different heights.

[0043] An arc-shaped blade groove 211 is provided in the middle of the edge of the right-angled blade body 21 near the cutting disk 2. The right-angled blade body 21 is mounted in an inlaid manner with the cutting disk 2 through the arc-shaped blade groove 211, and can be half-wrapped in the blade part of the cutting disk 2.

[0045] The second electric push rod 43 is inserted on the electric slide 11, and the first electric push rod 42 is located at the front and rear positions of the vertical plate 41 and is inserted on the electric slide 11 in a left-right symmetrical manner. A socket 111 is opened on the top of the electric slide 11, and the socket 111 is opened around the second electric push rod 43 in a centrally symmetrical manner, and the top of the second angle piece 48 is hinged to the top of the first angle piece 45, and the second angle piece 48 and the first angle piece 45 are assembled into a triangular frame structure.

[0046] The corner block 47 is installed above the triangular frame structure through the first electric push rod 42 and the top block 46. The surface of the third electric push rod 49 is fixedly connected with a fan-shaped plate 410 in a centrally symmetrical shape. There are two fan-shaped plates 410, and the two fan-shaped plates 410 are respectively inserted in the middle of the second corner piece 48 and the first corner piece 45. When the third electric push rod 49 is activated to lift the second corner piece 48 and the first corner piece 45 obliquely upward with the help of the top plate 412, the fan-shaped plate 410 is used to limit and guide the movement trajectory of the second corner piece 48 and the first corner piece 45 rotating around the top hinge part of the two, to ensure that the angle change between the second corner piece 48 and the first corner piece 45 is consistent, and to ensure the smooth restoration of the second corner piece 48 and the first corner piece 45.

[0047] When in use, under the guidance of the horizontal limit of the guide frame 3, the angle steel is conveyed forward from the middle of the back side of the cutting equipment, so that the angle steel is located in the middle of the inner side of the angle groove 411 under the guidance of the limit of the angle groove 411, and the triangular frame structure composed of the first angle piece 45 and the second angle piece 48 installed at the front and rear positions of the vertical plate 41 is fitted and supported for the bending angle of the angle steel, and the second electric push rod 43 and the third electric push rod 49 are sequentially activated to extend to lift the angle steel, and at the same time, the top angle of the triangular frame structure is changed through the top plate 412 at the top of the third electric push rod 49, so that the first angle piece 45 and the second angle piece 48 are finally tightly fitted and contacted on the angle steel, so that the current angle of the triangular frame structure matches the bending angle of the angle steel; then, by activating the first The electric push rod 42 retracts, and the top block 46 drives the corner block 47 to fit and clamp and limit the top of the angle steel, so that the top block 46 and the corner block 47 are respectively located at two positions of the angle steel with the first angle piece 45 and the second angle piece 48 for clamping, positioning and locking, so as to stably clamp and limit the front and rear parts of the angle steel to be cut. Then, the second motor 20 is activated to drive the cutting disk 2 to rotate inside the shell 18, and the first motor 5 is activated to drive the transmission gearbox 14 and the transmission plate assembly 15 to push the crossbeam plate 16 through the kit 17 along the guide rod 13, driving the cutting disk 2 vertically downward into the inside of the vertical plate 41 to cut the angle steel, and under the return movement of the transmission plate assembly 15 in the second half of the rotation, the cutting disk 2 is driven to rise quickly to complete the automatic cutting process of the angle steel by the cutting disk 2.

[0048] When the cutting disc 2 is used to cut the angle steel, the two right-angled blade bodies 21 are stored horizontally inside the housing 18 and do not participate in the cutting process. Only when the angle steel is partially cut incompletely, the micro motor 22 can be used to drive the main gear 221 to mesh with the double gear set 212 to rotate the right-angled blade body 21 stored in the storage cavity 182 around the axle pin in the middle of the double gear set 212 by a flat angle, so that the right-angled blade body 21 is wrapped and blocked on the cutting disc 2 through the arc-shaped blade groove 211, specifically, it is wrapped and blocked in a semicircular ring shape just below the cutting disc 2, and the right-angled blade body 21 and the cutting disc 2 are connected. A rectangular blade plate structure with a semicircular bulge in the middle is formed, and the rectangular blade plate assembled by the two is used to expand the cutting cross section of the cutting disc 2, and the angle steel is transversely cut in a short time to supplement the edges of the angle steel that have not been cut cleanly, thereby eliminating the cutting dead corners. At the same time, a second cutting operation form for cutting the angle steel is also provided: one is the rotation cutting provided by the cutting disc 2, and the other is the chopping-type cutting with a larger area and a longer transverse cutting surface formed by the cutting disc 2 combined with the right-angled blade body 21, which can be adaptively selected according to the cutting condition of the angle steel and the cutting requirements.

[0049] At the same time, the cutting disc 2 and the right-angled blade body 21 can be used alternately to solve the problem of local blade curling or damage due to excessive fatigue during continuous high-intensity cutting of the angle steel by the cutting disc 2 or the right-angled blade body 21; at the same time, the cutting disc 2 can be assembled and stored on the right-angled blade body 21 through the arc-shaped blade groove 211, which plays a role in protecting the blade of the cutting disc 2 and preventing foreign matter from directly contaminating the blade of the cutting disc 2 and affecting the cutting accuracy of the cutting disc 2.

[0050] In addition, when the machine is shut down and not in use, the right-angled knife body 21 is rotated and assembled under the cutting disk 2 and assembled with the cutting disk 2. After the first motor 5 is activated to drive the right-angled knife body 21 to cut into the inside of the vertical plate 41, the machine is immediately shut down. The right-angled knife body 21 can be stored on the inside of the vertical plate 41, and the processed cutting disk 2 can be stored and protected on the inside of the arc-shaped blade groove 211. In this way, two sets of different knives can be stored and protected at the same time, while also avoiding the risk of injury from the above two sets of knives during shutdown, thereby improving the safe use performance of the cutting equipment and the diversity of cutting functions.

[0051] By adjusting the angle between the first angle piece 45 and the second angle piece 48 with the help of the top plate 412 through the third electric push rod 49, and pulling down the top block 46 and the corner block 47 when the first electric push rod 42 is retracted, the top of the angle steel is limited by the fit, so that the positioning component 4 can not only fit, clamp and limit the points on the front and rear sides of the cut part of the angle steel, but also avoid deformation and displacement of the cut part, effectively improving the cutting accuracy and smoothness of the angle steel when it is cut, and also ensuring the flatness and consistency of the cut surface of the angle steel.

[0052] By sliding the electric slide 11 forward and backward along the long rod 10 on the square plate frame 1, the existing conveying device can be used in conjunction with the cutting device to move the conveying direction of the angle steel in the opposite direction, thereby accelerating the guiding progress of the angle steel on the cutting device, and at the same time, the specific cutting position of the angle steel can be adjusted independently; by activating four servo motors 7 at the same time, the crossbeam 9 can be raised and lowered in the vertical guiding direction of the screw rod 8 through the ball spline 91 under the guidance of the screw rod 8, and the overall cutting operation height of the electric slide 11 can be adjusted independently to adapt to the conveying of the angle steel by conveying devices of different heights.

[0053] The second embodiment is based on the first embodiment. Fig. 9 As shown, the vertical plate member 41 is a plate-like frame positioning structure assembled by two rectangular plates and four bolts. Angle grooves 411 are opened in the middle of the two rectangular plates from front to back, and the top shape of the angle groove 411 is W-shaped, which can limit the top of the angle steel and limit and block the top of angle steels of different models and sizes. The different models and sizes here specifically refer to the bending angles of the angle steels; the middle parts of the non-hinged ends of the first angle member 45 and the second angle member 48 are fixedly installed with arc-shaped clips 451, and the non-hinged ends of the first angle member 45 and the second angle member 48 are mutually buckled through the arc-shaped clips 451, and the first angle member 45 and the second angle member 48 are installed in a fit with the third electric push rod 49 through the arc-shaped clips 451, and the fan plate 410 is inserted into the arc-shaped clips 451.

[0054] When in use, the W-shaped structural design of the top of the angle groove 411 enables the vertical plate 41 to cooperate with the first angle piece 45 and the second angle piece 48 through the angle groove 411, as well as the top block 46 and the corner block 47 to adapt to the cutting processing of angle steels with different bending angles.

[0055] The third embodiment is based on the first and second embodiments. Figure 3 and Figure 4 As shown, a storage groove 171 is provided on the surface of the kit 17, and the right-angled blade body 21 is installed in engagement with the kit 17 through the storage groove 171. When the right-angled blade body 21 is stored as a whole inside the shell 18, the end of the right-angled blade body 21 away from the cutting disk 2 can be stored inside the storage groove 171. The right-angled blade body 21 can be used as an intermediate structure for combining the kit 17 and the shell 18 into a whole, to ensure that the shell 18 can perform vertical lifting and lowering movements between the two guide rods 13 under the horizontal guidance of the kit 17 and the crossbeam plate 16, to ensure the stability of the cutting disk 2 installed in the middle of the inner side of the shell 18 when cutting the diagonal steel, and to ensure the cutting accuracy of the diagonal steel.

[0056] When used, pass.
