Description

Technical Field

[0001] This utility model relates to the technical field of roller pressing structures, and in particular to a roller press that adaptively adjusts its height and angle. Background Technology

[0002] Heat pipe direct-contact radiators (hereinafter referred to as the product) require roll forming for leveling. Conventional roll forming machines perform fixed-distance roll forming. When the product tilts due to tolerances or other reasons, the roll forming process becomes: roll forming once (NG), reduce the distance, roll again, and if it's NG again, continue reducing the distance until it's OK. Each roll forming only covers a local area, not the entire plane, requiring multiple distance adjustments. This is time-consuming, has low throughput, and a high defect rate. This is why fixed-distance roll forming cannot be used when the product's placement surface and the force-bearing surface are not parallel. Utility Model Content

[0003] One objective of this invention is to provide a roller press that adaptively adjusts its height and angle. By controlling the wedge-shaped top blocks with side-push cylinders around the perimeter, the H-shaped fixed template is lifted up. The product on the product placement plate can adaptively adjust its height and angle to overcome the influence of tilting and fit onto the roller pressing device for planar roller pressing.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 5 As shown in this embodiment, an adaptive height and angle adjustment roller press includes a worktable 1, a roller pressing device, a large air cylinder 2, an H-shaped fixed template 3, and a product placement plate 4. The roller pressing device is installed above the worktable 1, the large air cylinder 2 is fixed below the H-shaped fixed template 3, and a connecting rod 5 connects the moving arm of the large air cylinder 2 to the product placement plate 4. The product placement plate 4 moves on the H-shaped fixed template 3. Side push cylinders 6 are distributed along the edge of the worktable 1, and a wedge-shaped top block 7 is locked on the moving arm of the side push cylinder 6. The lower sides of the H-shaped fixed template 3 are inclined surfaces, which cooperate with the wedge-shaped top block 7.

[0023] Product 23 is placed on product placement plate 4. Side push cylinder 6 extends its moving arm, and wedge-shaped top block 7 lifts H-shaped fixed template 3 under the action of the inclined surface. At this time, the upper surface of product 23 is continuously bonded to the roller pressing device along a long line. When the large cylinder 2 extends its moving arm, product placement plate 4 will move on H-shaped fixed template 3. The roller pressing process can be completed in one round, without the need for multiple gradual roller pressing distances, thus improving production capacity and yield.

[0024] Furthermore, the roller pressing device includes two side plates 8 and rollers 9. The side plates 8 are located on both sides of the worktable 1. The upper end of the side plates 8 is provided with a round hole 10. Both ends of the rollers 9 are inserted into the round holes 10. The upper cover plate 11 is locked on the two side plates 8. Two sets of slide rails 12 are provided on the H-shaped fixed template 3. The lower end of the product placement plate 4 is installed with a transition plate 13. A slider 14 is installed on the transition plate 13 and slides on the slide rails 12. Adjustable screws 15 are connected to both ends of the transition plate 13. A limit block 16 is locked on the H-shaped fixed template 3. The limit block 16 is provided with an adjustable screw. Rod 17, adjustable screw 17 and adjustable screw 15 contact limit, buffer sensor 22 is installed on limit block 16, buffer sensor 22 senses adapter plate 13, product placement plate 4 is provided with L-shaped product positioning block 18 and product positioning guide groove 19, L-shaped product positioning block 18 is locked on product positioning guide groove 19 by screws and nuts, H-shaped fixed template 3 is provided with countersunk hole, spring 20 and connecting screw 21 are placed in countersunk hole, hexagonal nut is provided between worktable 1 and H-shaped fixed template 3, connecting screw 21 passes through spring 20 and locks with hexagonal nut.

[0025] The workbench 1 is a large base with a pre-set circular hole 10. First, lock one side plate 8, and the roller 9 passes through the circular hole 10 from the inside. The other side plate 8 is fitted onto the other end of the roller 9 through the circular hole 10 from the outside to the inside. Adjust the hole position to align with the pre-set hole on the workbench 1 and lock it. Then, lock the upper cover plate 11 on the side plate 8 so that the upper cover plate 11, the side plate 8, and the roller 9 form a closed and stable roller pressing device.

[0026] Two L-shaped product positioning blocks 18 are brought together to clamp the product 23 onto the product placement plate 4. The side-push cylinders 6 around the H-shaped fixing template 3 are controlled to push inward through the cooperation of the inclined surfaces. The product placement plate 4 is pushed upward and contacts the roller shaft 9. The large air cylinder 2 controls the adapter plate 13 on the H-shaped fixing template 3 to drive the product placement plate 4 to move back and forth. When the buffer sensor 22 is subjected to force, it sends a signal to the magnetic switch on the large air cylinder 2 to reduce the force. The large air cylinder 2 is set with a custom speed and number of reciprocations by the PLC controller.

[0027] The connecting screw 21 and hexagonal nut have the functions of preventing loosening and spacing. The thrust of the spring 20 and the self-weight of the product placement plate 4 ensure that it falls back to the initial position after the roller pressing is completed. It is lifted in four directions and adaptively adjusts the height and angle of the product placement plate 4 to overcome the effect of tilting. This ensures that the product 23 makes long line contact with the roller shaft 9 at the moment of contact. The large air cylinder 2 pulls and moves, and the long line contact is a large surface, which ensures the high-quality roller pressing effect of the product 23.

[0028] Furthermore, the side plate 8 on the side of the roller 9 can be telescopically adjustable in length, allowing for a wider range of application heights.

[0029] It should be stated that the above specific embodiments are merely preferred embodiments of this utility model and the technical principles used therein. Within the scope of the technology disclosed in this utility model, any changes or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
