Description

Technical Field

[0002] Aluminum veneer refers to a building decoration material that is processed by chromization and other treatments and then fluorocarbon spraying technology. Aluminum veneer is often designed to be curved due to its strong plasticity and architectural design requirements, and hyperbolic aluminum veneer is one of them. In the production process of hyperbolic aluminum veneer, arc pressing equipment is often needed, and the aluminum veneer is repeatedly rolled by the arc pressing equipment to achieve the required curved surface; for example, the existing public document CN214866463U-A curved surface forming device for hyperbolic aluminum veneer and the existing public document CN118513409B-Aluminum veneer automatic arc rolling device and arc rolling process both disclose a forming device for curved aluminum veneer. Although the existing arc pressing device can realize the effective production and forming of aluminum veneer, the existing arc pressing device has the following shortcomings in actual use: 1. The existing arc pressing equipment for the production of hyperbolic aluminum veneers can only realize the forming of single-curved aluminum veneers when in use. When facing the production of hyperbolic aluminum veneers, the staff needs to turn the aluminum veneer over to realize the hyperbolic surface, which indirectly increases the labor intensity of the staff; 2. The existing arc pressing equipment for the production of hyperbolic aluminum veneers can only realize the molding of aluminum veneers with fixed curvatures when in use, and cannot mold curved aluminum veneers with different curvatures according to actual needs, and the overall practicality is poor; 3. When facing the arc pressing of thicker aluminum veneer, repeated rolling of the aluminum veneer will cause metal fatigue on the arc surface of the aluminum veneer, and the appearance of metal fatigue will indirectly reduce the quality of the aluminum veneer, thereby affecting its service life; Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems.

[0035] See Figure 5 As shown, the two fixed rollers 101a in the positioning assembly 101 are arranged in parallel along the same horizontal direction with an axis, so that the two fixed rollers 101a can limit the position of one side of the aluminum plate, and a first rotating rod 101a-1 is fixedly sleeved in the fixed roller 101a, and both ends of the first rotating rod 101a-1 are rotatably sleeved with a first end block 101a-2 through a rolling bearing.

[0036] See Figure 3 , Figure 4 and Figure 7As shown, the arc pressing assembly 102 includes a pressing roller 102a, a chain 102b, a first motor 102c and a first mounting frame 102d. The pressing roller 102a is arranged on one side between the two fixed rollers 101a, and a first U-shaped frame 102a-3 is arranged on the side of the pressing roller 102a away from the fixed roller 101a. A second rotating rod 102a-1 is fixedly sleeved in the pressing roller 102a, and both ends of the second rotating rod 102a-1 are rotatably connected to the first U-shaped frame 102a-3 through rolling bearings. A first hydraulic cylinder 102d-1 is fixedly arranged in the middle of the outer side wall of the closed end of the first U-shaped frame 102a-3. A first T-shaped column 102a-4 is symmetrically fixed, and this arrangement can play a role of limiting and guiding the extension and contraction of the first hydraulic cylinder 102d-1. The fixed section of the first hydraulic cylinder 102d-1 is fixedly sleeved on the first mounting frame 102d, and the first T-shaped column 102a-4 is slidably sleeved on the first mounting frame 102d. A second gear plate 102a-2 is fixed on one end of the second rotating rod 102a-1, and the second gear plate 102a-2 is transmitted to the third gear plate 102c-1 through the chain 102b. The third gear plate 102c-1 is fixed on the free end of the output shaft of the first motor 102c, and the first motor 102c is fixed on the first U-shaped frame 102a-3; When the above-mentioned arrangement is in use, the rotation of the third gear plate 102c-1 can be realized through the operation of the first motor 102c, the transmission of the chain 102b can realize the rotation of the second gear plate 102a-2 driving the pressure roller 102a, and the extension and retraction of the first hydraulic cylinder 102d-1 can realize the movement of the pressure roller 102a in the vertical direction.

Due to the spiral matching arrangement between the screw rod 201b-1 and the connecting plate 201b, the two side guard plates 201 can be synchronously moved along the axial direction of the screw rod 201b-1 under the rotation of the screw rod 201b-1, thereby realizing the adjustment of the positions of the two arc pressing assemblies 102.

[0039] In addition, it should be noted that the device also includes a controller (not shown in the drawings) for controlling various electrical components, and the controller is arranged at a position convenient for the operator to operate. Example 2

[0040] Reference Figure 3 , Figure 5 and Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment, except that in order to be able to adjust according to production requirements in actual use to achieve the forming of aluminum veneers with different curved surface radians, this embodiment is proposed.

[0041] Specifically, rectangular frames 101b are symmetrically provided at both ends of the fixed roller 101a, and first limiting grooves 101b-3 are provided on the upper and lower side plates of the rectangular frame 101b along the long side direction. The two first end blocks 101a-2 located at the same end of the fixed roller 101a in the positioning assembly 101 are gap-fitted in the same rectangular frame 101b. A driving block 101a-3 is fixedly provided on the top surface of the first end block 101a-2, which passes through the first limiting groove 101b-3 and extends to the top of the rectangular frame 101b. Extension plates 101b-2 are symmetrically fixedly provided on both sides of the top surface of the rectangular frame 101b. First limiting strips 101a-4 that are gap-fitted with the first limiting groove 101b-3 are fixedly provided on the upper and lower side surfaces of the first end block 101a-2. This arrangement can play a role of limiting and guiding the movement of the first end block 101a-2. A screw column 101c is arranged above one of the rectangular frames 101b, and the two ends of the screw column 101c are respectively rotatably sleeved on the extension plate 101b-2 through rolling bearings, and the two driving blocks 101a-3 are screwed on the same screw column 101c to realize the two driving blocks 101a-3 moving toward or opposite to each other when the screw column 101c rotates; a first guide column 101b-1 for sliding sleeve connection of the driving block 101a-3 is arranged above the other rectangular frame 101b where the screw column 101c is arranged, and the two ends of the first guide column 101b-1 are respectively fixedly connected to the extension plate 101b-2, and this arrangement can play a role of limiting and guiding the movement of the driving block 101a-3; When the above-mentioned arrangement is in use, through the rotation of the screw rod 101c, and because of the spiral matching arrangement of the screw rod 101c and the driving block 101a-3, under the rotation of the screw rod 101c, the two driving blocks 101a-3 can drive the two first end blocks 101a-2 to move toward or oppositely, thereby realizing the two fixed rollers 101a to move toward or oppositely to adjust the distance between the two fixed rollers 101a, and then in combination with the position adjustment of the pressure roller 102a in the vertical direction, the forming of curved surfaces with different curvatures can be achieved. Example 3

[0042] Reference Figure 3 and Fig.11 , which is the third embodiment of the present invention, is based on the previous embodiment, except that this embodiment is proposed in order to improve automation so that the two positioning components 101 can be automatically adjusted when facing different curvature surfaces.

[0043] Specifically, a first gear plate 101c-1 is fixedly provided at one end of the screw column 101c, and the two first gear plates 101c-1 in the two positioning assemblies 101 are close to each other and meshed with the same gear column 103, and the axes of the gear column 103 and the first gear plate 101c-1 are arranged parallel to each other in a vertical plane; a rotating shaft 103a is fixedly provided at one end of the gear column 103, and the other end of the rotating shaft 103a is engaged in the output end of the second motor 103a-1. When the above arrangement is in use, the rotating shaft 103a can be rotated through the operation of the second motor 103a-1, and then the rotating shaft 103a drives the gear column 103 to rotate. Because the gear column 103 and the two first gear plates 101c-1 are meshed, under the rotation of the gear column 103, the two first gear plates 101c-1 can drive the screw columns 101c on the two positioning assemblies 101 to rotate synchronously.

[0044] Furthermore, an electric push rod 103b-1 is fixedly provided on one side surface of the mounting seat 103b for fixing the second motor 103a-1 along the axial direction of the rotating shaft 103a, and second guide columns 103b-2 are symmetrically fixedly provided on the mounting seats 103b on both sides of the electric push rod 103b-1. The fixed section of the electric push rod 103b-1 is fixedly sleeved on the vertical plate of the second U-shaped frame 201a, and the second guide column 103b-2 is slidably sleeved on the second U-shaped frame 201a. This arrangement can play a role of limiting and guiding the extension and retraction of the electric push rod 103b-1.
