Description

Technical Field

[0001] The utility model relates to the technical field of arc rolling machines, in particular to a hydraulic arc rolling machine for aluminum veneer plates. Background Art

[0002] Aluminum plate hydraulic arc rolling machine is a mechanical equipment used for processing aluminum plates. It adopts a hydraulic transmission system to control the operation of the machine and the accuracy of arc rolling by controlling the pressure of hydraulic oil. This kind of equipment usually has the characteristics of high efficiency, high precision and easy operation, and is widely used in the aluminum plate processing industry.

[0003] A Chinese patent with authorization announcement number CN219597768U discloses an arc rolling machine, which can adjust the distance between the third roller and the first roller or the third roller and the second roller through an adjustment mechanism. The third roller can be adjusted to move upward or downward according to the thickness of the metal sheet to ensure that the third roller is pressed tightly on the metal sheet, which is very efficient in the bending process of the metal sheet.

[0004] However, when the arc rolling machine mentioned above actually adjusts the position of the third roller, two people are required to turn the handles from both ends of the third roller at the same time to ensure that the two ends of the third roller move down synchronously. The operation is more troublesome. At the same time, the outer curvature of the third roller is fixed, and the arc rolling curvature cannot be adjusted according to processing requirements, so the applicability is low. Utility Model Content

[0005] In view of the problems existing in the background technology, a hydraulic arc rolling machine for aluminum veneer is proposed. By providing an adjustment mechanism composed of a bidirectional screw, a nut pair and a connecting rod, a worker can adjust the height of the pressing roller by a single operation; at the same time, a limit connection mechanism cooperating with a shaped frame is provided on the pressing roller, and the pressing roller can be quickly disassembled from the shaped frame through the limit connection structure, so that the pressing roller with different arcs can be replaced according to different processing requirements, thereby expanding its application range.

[0006] The utility model provides an aluminum plate hydraulic arc rolling machine, comprising

[0007] A base having two sets of vertical plates, two sets of conveying rollers are rotated side by side between the two sets of vertical plates, and a hydraulic driving box for driving the conveying rollers to rotate is arranged on the outer side of one side of the vertical plates;

[0010] Preferably, the pressure roller assembly includes bending columns, a U-shaped frame, and pressure rollers. There are four groups of bending columns, which are respectively installed on both sides of the opposite sides of the two vertical plates. Connecting blocks are slidably arranged on the four groups of bending columns. A U-shaped frame is connected between the four connecting blocks. The pressure rollers are movably connected to the inside of the U-shaped frame through a limit connection mechanism.

[0011] Preferably, the limit connection mechanism includes

[0012] Connecting shafts that are rotatably arranged at both ends of the pressure roller through bearings, and grooves are formed at the ends of the connecting shafts facing away from the pressure roller;

[0013] A tension spring is arranged inside the groove. One end of the tension spring is connected to the end wall of the groove, and the other end is connected to a sliding plate. The sliding plate is slidably connected to the groove; and

[0014] A pull shaft is arranged on one side of the sliding plate. One end of the pull shaft passes through the groove and is connected to a pull plate, and clamping columns are symmetrically arranged inside the pull plate.

[0015] Preferably, notches for inserting the connecting shafts and clamping grooves located on both sides of the notches are formed on the two vertical sections of the U-shaped frame, and the clamping columns are snap-fitted with the corresponding clamping grooves.

[0016] Preferably, the adjusting mechanism includes a bidirectional screw, a nut pair, and a connecting rod. The bidirectional screw is rotatably arranged between the two vertical plates. One end of the bidirectional screw passes through the corresponding vertical plate and is connected to a handle. Nut pairs are symmetrically arranged on the bidirectional screw.

[0017] Preferably, left-handed threads and right-handed threads that are opposite to each other are formed at the connection points of the bidirectional screw and the two nut pairs.

[0018] Through the above technical solutions, that is, the rolling arc machine disclosed in the present invention is provided with an adjusting mechanism composed of a bidirectional screw, a nut pair, and a connecting rod, enabling the staff to adjust the height of the pressure roller by single-person operation, and further enabling the distance between the pressure roller and the conveying roller to be adjusted correspondingly according to the thickness of different aluminum materials; at the same time, a limit connection mechanism that cooperates with the U-shaped frame is arranged on the pressure roller. The pressure roller can be quickly disassembled from the U-shaped frame through the limit connection structure, facilitating the replacement of pressure rollers with different arcs according to different processing requirements, improving the overall adjustability and expanding its application range.

It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] Embodiment 1

[0027] like Figure 1-Figure 4 As shown, the utility model proposes a hydraulic arc rolling machine for aluminum single plate, including a base 1, a pressure roller 7 assembly and an adjusting mechanism, wherein vertical plates 2 are symmetrically arranged on the base 1, and two groups of conveying rollers 3 are rotated side by side between the two groups of vertical plates 2, wherein a hydraulic driving box 4 for driving the conveying rollers 3 to rotate is arranged on the outer side of one side of the vertical plates 2, and a pressure roller 7 assembly is symmetrically arranged above the two groups of conveying rollers 3, and the pressure roller 7 assembly has a limiting connection mechanism for replacing pressure rollers 7 with different curvatures, and a pressure roller 7 assembly for driving it to move vertically relative to the conveying roller 3 is arranged above the pressure roller 7 assembly, so that the distance between it and the conveying roller 3 can be adjusted according to the thickness of the aluminum material.

[0028] like Figure 1 As shown, the pressure roller 7 assembly includes a bending column 5, a cam frame 6 and a pressure roller 7. Four groups of bending columns 5 are provided, which are respectively installed on both sides of the opposite sides of the two groups of vertical plates 2. Connecting blocks 8 are slidably provided on the four groups of bending columns 5. The cam frame 6 is connected between the four groups of connecting blocks 8. The pressure roller 7 is movably connected to the inner side of the cam frame 6 through a limiting connection mechanism.

[0029] like Figure 2 As shown, a pipe sleeve located outside the bending column 5 is also provided on the connecting block 8.

[0030] like Figure 4 As shown, the limit connection mechanism includes

[0031] A connecting shaft 9 is rotatably arranged at both ends of the pressure roller 7 through a bearing, and a groove 10 is formed at one end of the connecting shaft 9 away from the pressure roller 7;

[0032] A tension spring 11 is provided inside the groove 10, one end of the tension spring 11 is connected to the end wall of the groove 10, and the other end is connected to the slide plate 12, and the slide plate 12 is slidably connected to the groove 10; and

[0033] A pull shaft 13 is arranged on one side of the slide plate 12 , one end of the pull shaft 13 passes through the groove 10 and is connected to a pull plate 14 , and a clamping column 15 is symmetrically arranged on the inner side of the pull plate 14 .

[0034] The distance between the two vertical sections of the cam frame 6 is the same as the length of the pressing roller 7, so that the cam frame 6 can horizontally limit the pressing roller 7 when assembling it.

[0035] like Figure 2 As shown, the two vertical sections of the shaped frame 6 are provided with a notch 16 for inserting the connecting shaft 9 and slots 17 located on both sides of the notch 16. The clamping column 15 is engaged with the corresponding slot 17, and the elastic tension of the tension spring 11 drives the pressure plate to move relative to the connecting shaft 9. During the movement, the clamping column 15 on the pressure plate is engaged in the slot 17, thereby limiting the assembly of the pressure roller 7.

[0036] Embodiment 2

[0037] like Figure 1-Figure 4 As shown, the utility model proposes a hydraulic arc rolling machine for aluminum veneer. Based on the above embodiment, this embodiment also records in detail the specific components of the adjustment mechanism and the connection method between the adjustment mechanism and the pressure roller 7 assembly.

[0038] like Figure 1 As shown, the adjustment mechanism includes a bidirectional screw 18, a nut pair 19 and a connecting rod 20. The bidirectional screw 18 is rotatably set between the two groups of vertical plates 2. One end of the bidirectional screw 18 passes through the corresponding vertical plate 2 and is connected to a handle 21, on which the nut pair 19 is symmetrically set. The connecting rod 20 is rotatably set between the nut pair 19 and the cam frame 6.

[0039] like Figure 1 As shown, the connection between the bidirectional screw 18 and the two sets of nut pairs 19 is provided with left-handed threads and right-handed threads in opposite directions.

[0040] In summary, when the utility model is in use, the handle 21 is turned, and the handle 21 drives the bidirectional screw 18 to rotate. During the rotation of the bidirectional screw 18, the cam frame 6 is driven to move vertically under the limit of the connecting block 8 and the bending column 5. During the movement, the distance between the pressure roller 7 and the conveying roller 3 can be adjusted according to the thickness of the aluminum single plate to be processed. The adjustment method is simple, and when it is necessary to replace the pressure roller 7 with different curvatures, the pull plate 14 is pulled outward. During the pulling process of the pull plate 14, the pull shaft 13 drives the slide plate 12 to move, and the slide plate 12 stretches the tension spring 11 to cause it to undergo elastic deformation. During the pulling process, when the clamping column 15 on the pull plate 14 is disengaged from the clamping groove 17, the pressure roller 7 can be disassembled as a whole, and the connecting shafts 9 at both ends thereof are disengaged from the cam frame 6 through the notch 16, thereby improving the convenience and work efficiency of the overall replacement operation of the pressure roller 7.

[0041] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
