[0027] The slideway group located on the right side of the main roller is arranged at an angle greater than 0° and less than 90° to the slideway on the left side.

[0028] Furthermore, the lifting mechanism is provided with two groups of lifts corresponding to the slideways, and the telescopic ends of each group of lifts are connected to the bearing seat;

[0029] The telescopic ends of each group of elevators rise and fall synchronously, and the telescopic direction of the telescopic ends of each group of elevators is consistent with the direction of the corresponding slideway.

[0030] Among them, the elevator drives the circle rollers upward, the center distance between the two circle rollers decreases, and the diameter of the workpiece after circle is smaller; the elevator drives the circle rollers downward, the center distance between the two circle rollers increases, and the diameter of the workpiece after circle is larger.

[0031] Furthermore, each group of elevators is provided with a control device for controlling the telescopic stroke of the telescopic end of the elevator.

[0032] Specifically, according to the circle diameter of the workpiece, the center distance between the main roller and the circle roller is calculated, and then the positions of the main roller and the circle roller are adjusted according to the center distance and the limit height of the limit block. First, the center distance between the two circle rollers is adjusted by driving the circle roller to slide along the slideway by the elevator, and then the main roller is driven by the first telescopic mechanism to swing with the swing body, and the swing position of the main roller is limited by the limit block so that the main roller reaches the position required for the circle of the workpiece, and with the cooperation of the second telescopic mechanism, the workpiece is pressed to avoid uneven force on both ends of the main roller, resulting in uneven gap between the main roller and the circle roller, causing misalignment of the workpiece after circle, which brings difficulties to subsequent processing.

[0044] The guide mechanism is a guide plate, which is fixed on the machine body and has an arc-shaped sliding groove.

[0045] Specifically, while the sheet is clamped by the main roller and the circle roller at the feed port, the fourth telescopic mechanism drives the support and the sheet to rotate along the fixed arc groove, thereby realizing pre-bending of the sheet; when the support is rounded to the horizontal feeding position, the pre-bent end of the sheet is tilted upward, and can smoothly enter the circle roller at the discharge port when rounding, avoiding impact on the circle roller and reducing the service life of the parts.

[0046] Furthermore, it also includes a discharge mechanism, which includes a fifth telescopic mechanism, a guide rod and a discharge plate;

[0047] The main body of the fifth telescopic mechanism is fixedly connected to the pendulum body, and the telescopic end of the fifth telescopic mechanism is fixedly connected to the stripper plate;

[0048] The guide rod is fixedly arranged on the machine body, and the guide rod passes through the unloading plate and extends in the unloading direction of the circled workpiece, and is used to guide the unloading of the unloading plate.

[0049] After the workpiece is circled, the main roller moves away from the circle roller under the drive of the first telescopic cylinder, and the unloading plate is driven by the fifth telescopic cylinder to push the circled workpiece out of the processing area to complete automatic unloading.

[0053] Preferably, it also includes a control element for controlling the rotation angles of the main roller and the ring roller and an incoming material detection element.

[0054] The control element may be an encoder or a sensor; the detection element may be a sensor or a detection switch, etc.

[0072] The present invention will be further explained below with reference to specific embodiments.

[0073] like Figure 1-3 As shown, a circle forming machine provided in this embodiment includes a machine body 10, a main roller 20, a circle forming roller 40, a power mechanism and a lifting mechanism 70;

[0074] The main roller 20 is rotatably disposed on the machine body 10 and can move closer to and away from the rounding roller 40. A pair of rounding rollers 40 are movably disposed on the machine body 10 and below the main roller 20 to accommodate rounding of workpieces of different diameters.

[0075] The lifting mechanism 70 is used to drive the ring roller 40 to rise or fall;

[0076] The power mechanism includes a rotating mechanism 50 and a first telescopic oil cylinder 60;

[0077] The rotating mechanism 50 is used to drive the main roller 20 and / or the ring roller 40 to rotate;

[0078] The first telescopic oil cylinder 60 is used to drive the main roller 20 to approach the circle roller 40 to clamp the workpiece for circle processing, or drive the main roller 20 away from the circle roller 40 to realize loading and unloading of the workpiece.

[0079] The main roller 20 is rotatably arranged on the machine body 10 via a pendulum 23;

[0080] The pendulum 23 is plate-shaped, and one end of the pendulum 23 is pivotally connected between the main vertical plate 12 and the rear vertical plate 14 of the body 10 via a rotating shaft 24;

[0081] The main roller 20 is pivotally connected to the other end of the pendulum 23 through the main shaft 21 .

[0082] A shaft sleeve 22 is provided at the other end of the pendulum body 23, and the main shaft 21 is rotatably inserted in the shaft sleeve 22. One end of the main shaft 21 extends from the shaft sleeve 22 and is fixedly connected to the main roller 20, and the other end of the main shaft 21 extends from the shaft sleeve 22 and is transmission-connected to the output shaft of the transfer case 52.

[0083] The cylinder rod of the first telescopic oil cylinder 60 is pivotally connected to the shaft sleeve 22 through the cylinder seat 1 61 ; the cylinder barrel of the first telescopic oil cylinder 60 is pivotally connected to the connecting plate 13 at the top of the body 10 through the cylinder seat 2 62 .

[0084] A limit block 25 is also provided on the shaft sleeve 22 for limiting the swing of the main roller 20 ; the limit of the limit block 25 can be adjusted according to the diameter of the circular workpiece.

[0085] In this embodiment, the limit position of the limit block 25 is controlled by the limit elevator 26. According to the different diameters of the workpiece circle, the swing position of the main roller 20 is also different, so the position of the upper limit block 25 of the sleeve is also changing. The limit position of the limit block 25 is determined by the extension and contraction of the telescopic end of the limit elevator 26.

[0086] Reference Figure 4 As shown, it also includes a pressing roller mechanism 30, which includes a second telescopic oil cylinder 31 and a V-shaped pressing block 32;

[0087] The cylinder barrel of the second telescopic oil cylinder 31 is fixedly mounted on the pressure roller bracket 33 , and the cylinder rod of the second telescopic oil cylinder 31 is fixedly connected to the top of the guide frame 34 ;

[0088] The pressure roller bracket 33 is located at the upper front of the machine body 10 and is fixedly connected to the main vertical plate 12;

[0089] The V-shaped pressing block 32 is rotatably connected to the lower portion of the guide frame 34 via a pin 35 and is located above the front end of the main shaft 21;

[0090] In this embodiment, the guide frame 34 can slide up and down along two vertical and parallel guide columns 36. The upper end of the guide column 36 is fixedly connected to the pressure roller bracket 33, and the lower end of the guide column 36 is fixedly connected to the front vertical plate 11 through the guide column support 37.

[0091] The second telescopic oil cylinder 31 drives the guide frame 34 and the V-shaped pressing block 32 to slide downward along the guide column 36 and press the front end of the main shaft 21 .

[0092] The pair of ring rollers 40 are arranged at asymmetrical intervals with respect to the main roller 20 .

[0093] A rotating shaft 41 is fixedly sleeved inside the circular roller 40; the rotating shaft 41 is rotatably mounted on the slideway via a bearing seat 42;

[0094] The bearing seat 42 drives the rotating shaft 41 and the circular roller 40 to slide along the slideway.

[0095] There are two groups of slides, each group includes an inner slide 43 and an outer slide 44 with the same sliding direction. The inner slide 43 is fixedly connected to the main vertical plate 12, and the outer slide 44 is fixedly connected to the front vertical plate 11.

[0096] A set of slideways located on the left side of the main roller 20 is arranged in the vertical direction;

[0097] A set of slideways located on the right side of the main roller 20 is arranged at an angle greater than 0° and less than 90° to the left side slideway.

[0098] The lifting mechanism 70 is provided with two groups of lifters corresponding to the slideways. Each group of lifters includes two lifters 71 corresponding to the inner slideway 43 and the outer slideway 44. The telescopic end of each lifter 71 is fixedly connected to the bearing seat 42.

[0099] The input ends of each group of two elevators 71 are connected together through a clutch 72, ensuring that the telescopic ends of each group of two elevators 71 are synchronously telescoped, and the telescopic direction of the telescopic ends of each group of two elevators 71 is consistent with the direction of the corresponding slide.

[0100] Among them, when the lifting group drives the circle rollers 40 upward, the center distance between the two circle rollers 40 decreases, and the diameter of the circled workpiece decreases; when the lifting group drives the circle rollers 40 downward, the center distance between the two circle rollers 40 increases, and the diameter of the circled workpiece increases.

[0101] The lifting and lowering of each set of elevators 71 is driven by a handwheel 73, and a counter (not shown) is installed on the handwheel 73 to record the rotation angle of the handwheel 73 when each specification of workpiece is circled, and further control the telescopic stroke of the telescopic end of the elevator 71.

[0102] Specifically, the center distance between the main roller 20 and the circle roller 40 is calculated based on the circle diameter of the workpiece, and then the positions of the main roller 20 and the circle roller 40 are adjusted based on the center distance and the limit height of the limit block 25. First, the center distance between the two circle rollers 40 is adjusted by driving the circle roller 40 to slide along the slideway by the elevator 71, and then the main roller 20 is driven by the first telescopic cylinder 60 to swing along with the pendulum 23. The limit block 25 limits the swing position of the main roller 20, so that the main roller 20 reaches the position required for the circle of the workpiece, and with the cooperation of the second telescopic cylinder 31, the workpiece is pressed to avoid uneven force on both ends of the main roller 20, resulting in uneven gap between the main roller 20 and the circle roller 40, causing misalignment of the workpiece after circled, which brings difficulties to subsequent processing.

[0103] Reference Figure 5-7 As shown, the automatic feeding mechanism 80 is arranged on the outer side of the left circle roller 40; it is used to feed the sheet material to the feed port of the circle roller 40 and pre-bend the sheet material.

[0104] The automatic feeding mechanism 80 includes a third telescopic cylinder and a push plate 82;

[0105] The push plate 82 is slidably mounted on the support 86; a push block 83 is fixedly mounted on the push plate 82 for limiting the length of the sheet metal; a plurality of mounting holes are evenly spaced apart on the push plate 82 for adjusting the position of the push block 83 according to sheet metal lengths;

[0106] The support 86 is provided with a first chute 861 and six second chute 862 . The first chute 861 is arranged along the sheet conveying direction, and the second chute 862 is arranged perpendicular to the first chute 861 .

[0107] The cylinder barrel of the third telescopic cylinder 81 is fixedly arranged at the bottom of the support 86, and the cylinder rod of the third telescopic cylinder 81 is fixedly connected to the push plate 82; the third telescopic cylinder 81 is used to drive the push plate 82 to reciprocate along the first slide groove 861;

[0108] The second chute 862 is symmetrically arranged on both sides of the first chute 861. Eight guide cylinders 84 are slidably arranged on the second chute 862. The guide cylinders 84 are rotatably sleeved on the support shaft 85.

[0109] The support shaft 85 drives the guide cylinder 84 to slide along the second sliding groove 862; it is used to guide the conveying direction of the sheet material and limit the width direction of the sheet material.

[0110] A fourth telescopic oil cylinder 87 is provided on the support 86. The cylinder barrel of the fourth telescopic oil cylinder 87 is hinged to the body 10, and the cylinder rod of the fourth telescopic oil cylinder 87 is hinged to the bottom of the support 86. It is used to drive the support 86 to rotate along the arc-shaped slide groove provided on the guide plate 88.

[0111] The guide plate 88 is fixedly mounted on the machine body 10 .

[0112] Specifically, while the sheet is clamped by the main roller 20 and the left circle roller 40, the fourth telescopic cylinder 87 drives the support 86 and the sheet to rotate along the arc groove on the guide plate 88, thereby realizing pre-bending of the sheet; when the support 86 is rounded to the horizontal feeding position, the pre-bent end of the sheet is tilted upward, and can smoothly enter the right circle roller 40 when circling, avoiding impact on the right circle roller 40 and reducing the service life of the parts.

[0113] This embodiment also includes a discharge mechanism 90, which includes a discharge plate 91, a guide rod 92 and a fifth telescopic cylinder 93;

[0114] The cylinder barrel of the fifth telescopic cylinder 93 is fixedly connected to the pendulum body 23, and the cylinder rod of the fifth telescopic cylinder 93 is fixedly connected to the discharge plate 91;

[0115] The guide rod 92 is fixedly arranged on the main vertical plate 12 . The guide rod 92 passes through the discharge plate 91 and extends toward the outside of the machine body, and is used to guide the discharge plate 91 to discharge materials.

[0116] After the workpiece is circled, the main roller 20 moves away from the circle roller 40 under the drive of the first telescopic cylinder 60, and the unloading plate 91, driven by the fifth telescopic cylinder 93, pushes the circled workpiece out of the processing area to complete automatic unloading.

[0117] The rotating mechanism 50 includes a reduction motor 51 and a transfer case 52. The transfer case 52 is provided with three synchronously rotating output shafts. The output shaft of the reduction motor 51 is connected to the input shaft of the transfer case 52 via a coupling 53. The three output shafts of the transfer case 52 are also connected to the main shaft 21 and the rotating shaft 41 via a coupling (not shown).

[0118] The three output shafts of the transfer case 52 output synchronously, which can ensure that the main roller 20 and the circle roller 40 rotate synchronously, reduce the friction between the main roller 20 and the circle roller 40 and the sheet material, and improve the circle quality of the sheet material.

[0119] This embodiment also includes an encoder for controlling the rotation angle of the main roller 20 and the ring roller 40 and an incoming material detection switch.

[0120] When the incoming material detection switch detects the sheet material, the second telescopic cylinder 31 drives the V-shaped pressure block 32 to descend and press the front end of the main shaft 21, and cooperates with the first telescopic cylinder 60 to drive the main roller 20 to press the sheet material. At the same time, the fifth telescopic cylinder 93 drives the support 86 to rotate to complete the pre-bending of the sheet material.

[0121] Control components and detection components improve the degree of automation of the equipment.

[0122] This embodiment can automatically circle workpieces with diameters ranging from 8 inches to 17 inches without replacing rollers.

[0123] The circle forming machine provided by the present invention has the following advantages:

[0124] The swing structure drives the main roller to solve the problem of uneven radial gap between the main roller and the circle roller caused by adjusting the spacing of the circle rollers, and meets the equipment requirements for circled plate thickness; a pair of asymmetrically arranged circle rollers with adjustable spacing is used to solve the problem of circled workpieces with diameters ranging from 8 inches to 17 inches without changing rollers; the same equipment can roll workpieces of different diameters without changing rollers, with a simple structure, easy maintenance and high production efficiency; the use of automated control components improves the automation rate of the equipment and reduces production costs.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
