Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate processing, in particular to a hydraulic clamp used for stretching aluminum plates. Background Art

[0002] The curtain wall of a commercial building is generally made of aluminum. Due to the requirements for architectural aesthetic lines, the structure of the curtain wall needs to present a certain arc line beauty. Therefore, the aluminum plate needs to be molded into a certain arc shape, and the skin stretching machine can achieve this goal.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-2As shown, the utility model provides a technical solution: a hydraulic clamp for stretching aluminum plates, comprising a clamping frame 1, which is movably mounted on a movable seat 2. The movable seat 2 is provided so that the clamping frame 1 can adaptively rotate following the aluminum plate. A partition 3 is longitudinally provided in the middle of the clamping frame 1, and multiple groups of reinforcement rods 4 are provided between the partition 3 and the clamping frame 1.

[0024] A retractable hydraulic cylinder 5 is provided on the clamping frame 1 , and a free end of the hydraulic cylinder 5 passes through the partition 3 and is connected to a push block 6 .

[0025] The upper and lower sides of the clamping frame 1 are provided with a slide 7. The slide 7 is trapezoidal in shape and has an inclined step at the bottom. A slide groove 8 is provided in the middle of the slide 7. The clamping frame 1 is also provided with two upper and lower clamping parts 9. The maximum distance between the two clamping parts 9 is less than the length of the push block 6. The purpose of this design is to prevent the two groups of clamping parts 9 from being completely separated. The distance between them cannot be greater than the length of the push block 6, otherwise the push block 6 is at risk of falling off. Secondly, when the two groups of clamping clamps 11 are fully closed, the distance between the middle parts of the two groups of clamping parts 9 cannot be less than the length of the push block 6, otherwise the push block 6 will interfere, making the clamping clamp 11 unable to be completely closed. A slide rail 10 is provided on the clamping part 9, and the slide rail 10 can be slidably installed in the slide groove 8.

[0026] The slide groove 8 is arranged to be inclined, and the hydraulic cylinder 5 can push the clamping part 9 to slide obliquely on the slide groove 8 so as to adjust the distance between the two clamping jaws 11.

[0027] The upper and lower clamping parts 9 are arranged on the outer sides of the push block 6, and the push block 6 can push the clamping parts 9 to move back and forth.

[0028] The clamping portion 9 is provided with clamping pliers 11 , and two sets of clamping pliers 11 are horizontally and parallelly distributed. The clamping pliers 11 are provided with anti-skid striped pads 12 , and the purpose of providing the anti-skid striped pads 12 is to prevent the aluminum plate from slipping.

[0029] It should be noted that the hydraulic clamp can be set in corresponding groups according to actual needs.

[0030] At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0031] When in use, the hydraulic cylinder 5 is turned on to drive the push block 6 to move outward (i.e., toward the slide 7), and then drive the clamping clamp 11 to move outward. At the same time, the slide rail 10 on the clamping part 9 at the top of the clamping clamp 11 slides down on the slide groove 8. Under this action, the two sets of clamping clamps 11 will be closed together, thereby quickly clamping the aluminum plate.

[0032] On the contrary, by resetting the hydraulic cylinder 5, the push block 6 pushes the clamping part 9 inward, thereby driving the clamping part 9 to slide upward on the slide groove 8, so that the two sets of clamping jaws 11 move away from each other, thereby releasing the aluminum plate.

[0033] To sum up, the hydraulic clamp used for stretching aluminum plates is driven by a hydraulic cylinder, and the clamping mechanism achieves the clamping purpose in a sliding self-locking movement. When clamping the aluminum plate, it is only necessary to start the hydraulic cylinder to drive the two clamping parts to slide and close together until the aluminum plate is clamped, and the shear force between the clamping parts and the slide seat is used to achieve the purpose of clamping self-locking to prevent the clamping clamp from slipping. Conversely, the clamping clamp can be loosened by resetting the hydraulic cylinder, thereby facilitating the removal of the aluminum plate and convenient operation.

[0034] It should be noted that the electrical components appearing in this article are all connected to an external main controller and 220V or 380V mains electricity, and the main controller can be a conventional known device that controls a computer, etc. Its control principle, internal structure, and control switch mode are all conventional means of the prior art, which are directly quoted here without further elaboration.
