DETAILED DESCRIPTION

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0033] like Figure 4 , Figure 5 As shown, a beveled volute shroud rounding machine provided in this embodiment includes an angle pressing mechanism 1, a rotary die mechanism 2, a supporting device 3, a pressing mechanism 4 and a power system 5.

[0034] like Figure 4 , Figure 5 As shown, the angle pressing mechanism 1 includes a first driving member 11, a forming die 12 and a mounting seat 13. The first driving member 11 can be a double-rod cylinder, and the forming die 12 is fixed on its telescopic rod. An R angle 14 is provided at one end of the forming die 12. The mounting seat 13 is used to fix the first driving member 11 on the rotating seat 25 of the rotary die mechanism 2.

[0035] like Figure 5 , Figure 6 As shown, the rotary mold mechanism 2 includes a frame 21, a contour mold core 22, a rotary support 23 and a rotary seat 25.

[0036] The frame 21 is a box-shaped workbench with a two-stage step structure. The power system 5 is installed on the lower step surface, and the pressing mechanism 4 is installed on the upper step surface. A slewing bearing 23 is installed on the front end surface of the upper step.

[0037] The power system 5 includes a servo motor 51 and a driving gear 52. The servo motor 51 is mounted on the frame 21, and its motor shaft is connected to the driving gear 52. The driving gear 52 is meshed with the slewing bearing 23.

[0038] The rotating seat 25 is fixedly mounted on the radial end surface of the slewing bearing 23. The slewing seat 25 is composed of a circular plate and a convex plate protruding from one end of the circular plate. The mounting seat 13 of the angle pressing mechanism 1 is fixed on the convex plate, and the profiling core 22 is fixedly mounted on the circular plate and concentrically, so as to drive the slewing bearing 23 to rotate.

[0039] The profiling die core 22 is provided with a lower die table 24 which is radially concave and adapted to the R angle 14. The forming die 12 is driven by the first driving member 11 to move up and down relative to the mounting seat 13, so that the R angle 14 approaches or moves away from the lower die table 24. When approaching, the R angle 14 and the lower die table 24 bend the enclosure to form an angle.

[0040] like Figure 4 , Figure 5As shown, the support device 3 includes a base frame 31, a tray 32 and an anti-tilt bar 33. The base frame 31 is arranged on the side of the rotary die mechanism 2 in the X direction and away from the lower die table 24. The upper end of the base frame 31 is provided with the tray 32 for the enclosure to pass through, and one end of the anti-tilt bar 33 is connected to the base frame 31, and the other end is suspended above the tray 32. The anti-tilt bar 33 is a rod structure, which is spaced apart from the enclosure 10 to prevent the other end (located at the end of the anti-tilt bar 33) from tilting when one end of the enclosure 10 is folded and rounded.

[0041] In order to prevent the enclosure 10 from being displaced during transportation, baffles are provided at both ends of the tray 32 perpendicular to the transportation direction of the enclosure 10 .

[0042] In this embodiment, the tray 32 has no conveying power and only supports the enclosure 10. In another embodiment, the tray 32 has conveying power and can be designed as a conveyor belt. When the enclosure 10 is placed on it, it drives it to be conveyed in the direction of the rotary die mechanism 2.

[0043] like Figure 5 As shown, the pressing mechanism 4 is located beside the rotary mold mechanism 2 in the Y direction, and the pressing mechanism 4 can be displaced along the Y direction and the Z direction so that the end of the pressing mechanism 4 is close to or away from the profiling mold core 22.

[0044] like Figure 5 , Figure 7 As shown, the pressing mechanism 4 includes a second driving member 41 , a base 42 , a roller 43 , a third driving member 44 , a linear guide rail 45 and a roller frame 46 .

[0045] The base 42 is mounted on the upper end of the frame 21 through a linear guide 45. The second driving member 41 is a cylinder, the cylinder barrel is fixed on the upper end surface of the frame 21, and the telescopic rod is connected to the base 42. The base 42 and the frame 21 are slidably connected along the Y direction through the linear guide 45.

[0046] The third driving member 44 can be a double-rod cylinder, which is vertically mounted on the base 42 (the cylinder barrel is fixed on the base 42), and the telescopic rod is fixedly mounted on the roller frame 46. The roller 43 is provided on the roller frame 46. The roller 43 rotates under the drive of the enclosure 10.

[0047] The present invention also provides a method for processing the above-mentioned beveled volute shroud rounding machine, comprising the following steps:

[0048] Step 1, preparation: the pressing mechanism 4 is in the initial state.

[0049] Step 2, board material: Figure 2 As shown, the enclosure 10 before processing is a plate-like structure;

[0050] The loading mechanism is used to place one end of the panel 10 on the lower die table 24 of the profiling core 22, and the other end is placed on the supporting device 3, and the unloading mechanism is retracted; or, the loading mechanism is used to place the panel 10 on the supporting device 3, the unloading mechanism is retracted, the supporting device 3 is started, and the panel 10 is horizontally transported to the lower die table 24 of the profiling core 22;

[0051] The feeding mechanism feeds the enclosure 10 into the side of the pressing mechanism 4 to avoid the anti-tilt rod 33.

[0052] Step 3, pressing the angle of the enclosure: start the pressing mechanism 1 to extend the forming die 12 toward the contouring die core 22 until the R angle 14 is pressed against the lower die table 24 to form a folded angle on the enclosure 10 .

[0053] Step 4: Rolling forming of the panel: Start the pressing mechanism 4, which is first displaced to the top of the panel 10 along the Y direction, and then lowers the end of the movement direction of the pressing mechanism 4 along the Z direction until it contacts the panel 10; start the power system 5, and the panel 10 is roll-formed along the outer ring of the profiling mold core 22 in the form of one clamping, one pressing, and one blocking. Among them, one clamping refers to the clamping of the forming mold 12 and the profiling mold core 22; one pressing refers to the downward pressing of the roller 43 of the pressing mechanism 4, and one blocking refers to the setting of the anti-tilt rod 33.

[0054] Step 5: The pressing mechanism 4 and the angle pressing mechanism 1 return to their respective initial states, and the enclosure 10 is unloaded.

[0055] The final structure of the enclosure 10 is as follows Figure 3 shown.

[0056] The beveled volute enclosure rounding machine can realize fully automated processing of automatic loading, automatic corner folding, and automatic rounding. Its automated program setting is not an improvement point of the present invention, and the existing programming method can be used.

[0057] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
