Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ventilation pipe processing, in particular to a hydraulic press for ventilation pipe processing. Background Art
[0002] Ventilation ducts are hollow pipes used for ventilation, mostly in round or square shapes. The production and installation of ventilation ducts involve plates, profiles, and other main finished materials. Ventilation ducts generally include purification system return air ducts, central air conditioning ducts, industrial supply and exhaust ducts, environmental protection system intake and exhaust ducts, mining gas extraction pipes, mining rubberized cloth ducts, and fire smoke ducts. Before processing ventilation ducts, the plates are easily deformed due to long-term storage, so the plates usually need to be leveled using a hydraulic press before processing. Existing hydraulic presses mainly use hydraulic cylinders to drive the pressure plate to apply pressure to the plate, so that the plate becomes flat under the action of external force. However, because the plate is not set to a leveling position on the hydraulic press, it is difficult for the center point of the plate to align with the center point of the pressure plate. After long-term use, the hydraulic cylinder is prone to force deviation, which in turn affects the leveling quality of the hydraulic press. To this end, we provide a hydraulic press for ventilation duct processing to solve the above problems. Utility Model Content

[0005] Preferably, the thickness of the pressing plate is greater than the thickness of the limiting plate, so that the pressing plate can contact the machine body.
[0006] Preferably, a plurality of rollers are rotatably arranged in the groove at the top front end of the machine body, and the plurality of rollers are arranged in parallel.

[0013] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0014] The utility model proposes a hydraulic press for processing ventilation pipes, including a machine body 1, wherein columns 2 are fixedly provided at the four corners of the top of the machine body 1, a top plate 3 is fixedly provided on the top of the multiple columns 2, a hydraulic cylinder 4 is installed through the inside of the top plate 3, and a pressing plate 6 is provided at the movable end of the hydraulic cylinder 4. The hydraulic cylinder 4 can drive the pressing plate 6 to press down, thereby leveling the plate on the top of the machine body 1, and electric slides 7 are fixedly installed in the grooves on both sides of the top of the machine body 1, and connecting plates 8 are fixedly provided on the sliders of the two electric slides 7. The two connecting plates 8 are close to each other. Limit plates 9 are fixedly provided on both sides. The electric slide 7 can drive the limit plates 9 to approach the plate through the connecting plate 8, and the two limit plates 9 can be laterally centered when close to the plate. A multi-stage cylinder 10 is fixedly installed on the top rear end of the body 1. A push plate 11 is fixedly provided on the movable end of the multi-stage cylinder 10. The multi-stage cylinder 10 can adjust the position of the push plate 11, thereby controlling the pushing depth of the plate. After the plate is leveled, the push plate 11 can be driven to move by the multi-stage cylinder 10, so that the push plate 11 can push the plate outward to facilitate the user to take out the plate.
[0015] Specifically, the pressing plate 6 and the hydraulic cylinder 4 are fixedly connected by a lifting plate 5, and a plurality of columns 2 are movable through the interior of the lifting plate 5. This design can increase the stability of the pressing plate 6 when pressing downward.
[0016] Specifically, the thickness of the pressing plate 6 is greater than the thickness of the limiting plate 9 so that the pressing plate 6 can contact the machine body 1, thereby increasing the application range of the hydraulic press.
[0017] Specifically, multiple rollers 12 are rotatably installed in the groove at the top front end of the body 1, and the multiple rollers 12 are arranged in parallel. The design purpose is to push the plate to the flattened area on the top of the body 1 through the rollers 12, thereby converting the original sliding friction into rolling friction.
[0018] Specifically, two parallel groove plates 13 are fixedly provided on one side of the limit plate 9 close to the connecting plate 8. A slide rail 14 is integrally formed at the top of the body 1 corresponding to the groove plate 13. The slide rail 14 is slidably set in the inner cavity of the groove plate 13. This design can increase the stability of the movement of the limit plate 9 through the cooperation of the groove plate 13 and the slide rail 14.
[0019] According to the personnel in this field, all electrical components and parts in this case are universal standard parts or parts known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires, and according to actual conditions, appropriate controllers are selected to meet control requirements. The specific connection and control sequence should refer to the following working principle. The electrical connection is completed in the order of working between the electrical components. The detailed connection means are well known in this field and will not be explained in detail for electrical control.
[0020] Working Principle: First, the multi-stage cylinder 10 is activated according to the size of the plate. The operation of the multi-stage cylinder 10 can adjust the position of the push plate 11, thereby controlling the advancement depth of the plate. The plate is then placed on the roller body 12 at the top of the machine body 1 and manually pushed into contact with the push plate 11. At this time, the two synchronously controlled electric slides 7 are activated. The electric slides 7 can drive the limit plates 9 to approach the plate through the connecting plate 8. The two limit plates 9 approach the plate to laterally center it, so that the plate, the pressure plate 6 and the hydraulic cylinder 4 are all on the same center line. The electric slide 7 then drives the limit plates 9 back to the initial position through the connecting plate 8. At this time, the hydraulic cylinder 4 is activated. The operation of the hydraulic cylinder 4 can drive the pressure plate 6 downward through the lifting plate 5, thereby achieving the leveling of the plate. After leveling is completed, the multi-stage cylinder 10 can push the plate forward through the push plate 11, so that the plate can return to the top of the roller body 12, making it easier for the staff to remove the plate. This centering and leveling ensures that the hydraulic cylinder 4 applies force evenly, which can increase the service life of the hydraulic press.
