[0040] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with the drawings.

[0041] As Figure 1 shown, the present application provides an embodiment of a cutting equipment of a profile frame, which can improve the splicing effect of the support frame and help improve the assembly efficiency of the support frame.

[0045] The feeding positioning mechanism 3 is used for feeding the profile frame 1 to the positioning sliding groove 41, and the profile frame 1 slides in the positioning sliding groove 41 when feeding forward.

[0046] Specifically, the feeding positioning mechanism 3 of the embodiment comprises a sliding trolley 31 and a clamping arm 32, the rack 2 is provided with a guide rail 21, the sliding trolley 31 is provided with a servo motor (not shown in the figure) for driving the sliding trolley 31 to slide on the guide rail 21, the clamping arm 32 is matched with the positioning sliding groove 41 and connected with the sliding trolley 31, the clamping arm 32 clamps the profile frame 1, so that the sliding trolley 31 feeds the profile frame 1 in a certain direction.

[0047] The first cutting mechanism comprises a cutting saw blade 51 and a rotary transmission wheel set, the saw blade of the cutting saw blade 51 is arranged obliquely downward, the cutting saw blade 51 is wound on the outer periphery of the rotary transmission wheel set, the cutting saw blade 51 is driven by the rotary transmission wheel set to transmit, and the cutting saw blade 51 always keeps a first inclination angle with the vertical direction to cut the rib plate 12.

[0048] The second cutting mechanism comprises a second lifting driving mechanism 61 fixed with the rack 2, a driving end of the second lifting driving mechanism 61 connected with a horizontal telescopic driving mechanism (not shown in the figure), a movable die 62 and the horizontal telescopic driving mechanism driven by the second lifting driving mechanism 61 to drive close to or away from the cutting positioning mechanism 4, and the movable die 62 is provided with a punch 621 matched with the shearing groove 42, and the horizontal telescopic driving mechanism is used to drive the punch 621 to reciprocate along the shearing groove 42 and shear the profile body 11.

[0049] In combination Figure 6 and Figure 7 In the embodiment, the cutting track of the cutting saw blade 51 intersects with the cutting track of the punch 621.

[0050] In the embodiment, the cutting saw blade 51 is first used to cut the rib plate 12, and then the punch 621 is used to shear the profile body 11, so that the rib plate 12 is prevented from being warped and the profile body 11 is prevented from being deformed due to direct stamping and shearing of the entire profile frame 1; compared with direct sawing of the entire profile frame 1, the sawing thickness is small, and the sawing difficulty is reduced; in addition, the sawing and shearing are combined, on the one hand, the influence of sawing precision on splicing quality is reduced, the forming angle of the shearing surface of the profile body 11 is standard, the workpiece consistency is good, and the splicing quality is good, and on the other hand, the shearing of the profile body 11 enables the profile frame 1 to be directly bent and spliced, the amount of frame corner code is reduced, and the splicing and assembling efficiency is improved; the cutting saw blade 51 wound around the outer periphery of the rotary transmission wheel set can synchronously form two cutting tracks, and the production efficiency is improved.

[0051] Specifically, the rotary transmission wheel set comprises a driven wheel 52 and a driving wheel 53 driven by a driving motor 54. The rotating shaft 541 of the driving motor 54 is connected with the driving wheel 53 through a key 542. The driving wheel 53 and the driven wheel 52 are separately arranged on both sides of the conveying track of the profile frame 1, the wheel surfaces of the driving wheel 53 and the driven wheel 52 are both circular truncated cone surfaces with a wide upper part and a narrow lower part, and the cutting saw blade 51 is attached to the circular truncated cone surfaces. At least one of the driving wheel 53 and the driven wheel 52 is provided with a spiral limiting groove a on the wheel surface, and the spiral limiting groove a is provided with a preset distance from the upper end surface and the lower end surface of the driving wheel 53 or the driven wheel 52. The cutting saw blade 51 is provided with a protrusion 511 matched with the limiting groove a, the rotary transmission wheel set drives the cutting saw blade 51 to transmit and drives the cutting saw blade 51 to ascend and descend along the wheel surface.

[0052] When the cutting saw blade 51 descends along the wheel surface of the driving wheel 53 or the driven wheel 52 in the transmission process, the cutting from top to bottom of the web plate 12 is realized, and the cutting direction is unchanged, and the cutting is kept in the direction with the first inclination angle to the vertical direction; when the cutting reaches the position where the web plate 12 is connected with the profile main body 11, i.e. the groove bottom of the assembly groove 14, the cutting saw blade 51 can be reset along the cutting path by changing the rotation direction of the driving wheel 53.

[0053] The first cutting mechanism of the embodiment further comprises a first lifting driving mechanism 56 fixed with the rack 2, and the rotation transmission wheel sets are arranged on a jacking plate 57 driven to lift by the first lifting driving mechanism 56.

[0054] In order to keep the cutting saw blade 51 in the tension state and prevent the cutting saw blade 51 from loosening, the rotation wheel set of the embodiment further comprises a self-adaptive tension wheel 55, and the jacking plate 57 is provided with an elastic expansion piece 58, which abuts the self-adaptive tension wheel 55 against the cutting saw blade 51.

[0055] When the cutting saw blade 51 descends along the wheel surface of the driving wheel 53 or the driven wheel 52 in the transmission process, the self-adaptive tension wheel 55 abuts against the cutting saw blade 51 due to the action of the elastic expansion piece 58, so that the cutting saw blade 51 can still be closely attached between the driving wheel and the transmission wheel, the cutting saw blade 51 is kept in the tension state, and the cutting is ensured to be continuously and stably carried out.

[0056] In order to ensure that the profile frame 1 cut by the first cutting mechanism and the second cutting mechanism can be smoothly bent, and the profile main body 11 after cutting can be spliced, the angle of the first inclination angle is set to be greater than the angle of the second inclination angle in the embodiment, so as to avoid the situation that the web plate 12 interferes when the profile main body 11 after cutting is spliced.

[0057] The precision requirement of the first inclination angle is not high, and only the angle of the first inclination angle needs to be set to be greater than the angle of the second inclination angle, which reduces the cutting precision requirement of the cutting saw blade 51, and the cutting precision of the first cutting mechanism no longer affects the subsequent splicing effect of the profile frame 1.

[0058] Therefore, the final splicing effect of the profile frame 1 of the embodiment is determined by the second cutting mechanism. Since the second cutting mechanism of the embodiment adopts the mode that the movable die 62 cooperates with the cutting positioning mechanism 4 to complete the angle punching, and the punch 621 cooperates with the shearing groove 42 to cut, the standard of the formed angle and the workpiece consistency are good, and thus the bending of the profile frame 1 can obtain a good splicing effect.

[0059] When the second cutting mechanism works, the positioning sliding groove 41 limits the profile frame 1, the second lifting driving mechanism 61 drives the movable die 62 to approach the cutting positioning mechanism 4, when the punch 621 extends into the shearing groove 42, the punch 621 breaks the top surface of the profile frame 1 and is tangent to the shearing groove 42, further, the horizontal telescopic driving mechanism drives the punch 621 to reciprocate in the shearing groove 42, and the two side walls of the profile frame 1 located in the shearing groove 42 are sheared off by the punch 621.

[0060] By further bending the profile frame 1, the sheared edges on both sides of the profile main body 11 are folded and attached, which facilitates the next welding process and reduces the welding workload.

[0061] In order to make the angle of the profile frame 1 be punched and formed, and then be bent to make the sheared edges be folded and attached, which facilitates the subsequent welding, a second preset distance is arranged between the shearing groove 42 and the groove bottom of the positioning sliding groove 41.

[0062] The second inclined surface 422 is symmetrically arranged on both sides of the slot of the shearing groove 42, and the included angle between the second inclined surface 422 is smaller than the included angle between the first inclined surface 421. Since the cross section of the punch 621 is matched with the shearing groove 42, when the punch 621 breaks the top surface of the profile frame 1, the surface of the punch 621 corresponding to the second inclined surface 422 can extrude the two parts broken by the punch 621 downward, so as to avoid the two parts broken by the punch 621 from being in contact and generating a reverse force when being folded, which affects the folding and attachment of the sheared edges and the welding.

[0063] In addition, the application also provides a support frame forming method of a door and window based on the cutting equipment of the profile frame.

[0064] (1) The feeding mechanism directionally feeds the profile frame 1 according to the predetermined size, the rotary transmission wheel set of the first cutting mechanism drives the cutting saw blade 51 to drive and descend, so that the cutting saw blade 51 obliquely cuts the rib plate 12;

[0065] (2) The rotary transmission wheel set drives the cutting saw blade 51 to ascend and reset;

[0066] (3) The feeding mechanism continues to directionally feed the profile frame 1 according to the predetermined size, the second lifting driving mechanism 61 of the second cutting mechanism drives the horizontal telescopic driving mechanism and the movable die 62 to descend, when the movable die 62 descends to the position where the punch 621 breaks the top surface of the profile main body 11 and the punch 621 is tangent to the shearing groove 42, the horizontal telescopic driving mechanism drives the punch 621 to reciprocate in the shearing groove 42, so as to shear the two side walls of the profile main body 11; at the same time, the rotary transmission wheel set of the first cutting mechanism drives the cutting saw blade 51 to drive and descend, so that the cutting saw blade 51 obliquely cuts the rib plate 12 at the cutting position below the profile frame 1;

[0067] (4) the feeding mechanism continues to feed the profile frame 1 according to the predetermined size, and the second lifting driving mechanism 61 drives the horizontal telescopic driving mechanism and the movable mold 62 to reset; meanwhile, the rotary transmission wheel set drives the cutting saw blade 51 to rise and reset;

[0068] (5) repeat the step (3) and the step (4) for several times;

[0069] (6) cut the profile frame, bend and splice the positions cut by the first cutting mechanism and the second cutting mechanism, and finally connect the two ends of the cut profile frame by using the frame corner connector to form a complete support frame for doors and windows.

[0070] The above describes the preferred embodiments of the present application, and it should be noted that for those skilled in the art, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements are also considered within the protection scope of the present application.
