Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, and in particular to an automatic material discharge structure for a hydraulic press. Background Technology

[0002] When processing sheet materials such as container panels and decorative panels using hydraulics, a feeding platform loads and transports the blank sheet materials into a multi-layer hydraulic press for forming. CN203794192U discloses a pushing device for a feeding rack used in the production of high-gloss decorative panels, including push hook components on the left and right sides and a fixing block for fixing and guiding the push hooks. The push hook component includes a hook, a torsion spring, and a fixing shaft. One side of the fixing block is fixed in a frame groove, and the other side is milled with an L-shaped groove to accommodate the hook. The arc end of the hook is milled with an L-shaped groove to accommodate the torsion spring. The torsion spring is located in the groove of the fixing block, with a torsion handle locked on the hook and another torsion handle locked in the bottom groove of the fixing block and rotating around the fixing shaft. The size of the frame groove is slightly larger than the thickness of the fixing block, so that the fixing block is embedded in the groove along the thickness direction.

[0003] In the existing technology, a feeding platform is needed to feed the sheet into the hydraulic press during feeding. Similarly, after the sheet is hydraulically formed, it needs to be discharged through a discharge structure. The existing discharge structure requires multiple discharge components of different heights to discharge sheets of different heights, which is not flexible and has low discharge efficiency.

[0024] In the existing technology, a feeding platform is needed to feed the sheet into the hydraulic press during feeding. Similarly, after the sheet is hydraulically formed, it needs to be discharged through a discharge structure. The existing discharge structure requires multiple discharge components of different heights to discharge sheets of different heights, which is not flexible and has low discharge efficiency.

[0025] This utility model provides an automatic material discharge structure for a hydraulic press, such as... Figure 2As shown, in this embodiment, the automatic discharge structure of the hydraulic press includes a discharge unit 200 and a discharge conveyor belt 100. The discharge conveyor belt 100 is located on one side of the discharge mechanism. The discharge unit 200 is used to send the sheet metal out of the hydraulic press, and the discharge conveyor belt 100 is used to receive and transport the sheet metal sent out by the discharge unit 200. The discharge conveyor belt 100 includes a conveyor support, two conveyor rollers rotatably mounted on the conveyor support, a conveyor motor that drives the conveyor rollers to rotate, and a conveyor belt tensioned on the conveyor rollers. The formed sheet metal is transported from the hydraulic press to the next process through the discharge conveyor belt 100.

[0026] Regarding the discharge unit 200, such as Figure 1 As shown, the discharge unit 200 is configured as a discharge rack 201, a lifting cylinder 202, a lifting frame 203, and a telescopic discharge mechanism 206. The lifting cylinder 202 is installed on the top of the discharge rack 201, and the lifting frame 203 is provided at the lower end of the lifting cylinder 202. The lifting frame 203 is slidably mounted on the discharge rack 201. The top of the lifting frame 203 is connected to the piston end of the lifting cylinder 202, so that the lifting cylinder 202 can drive the lifting frame 203 to move up and down. The telescopic discharge mechanism 206 is installed on the lifting frame 203, so that the telescopic discharge mechanism 206 can move up and down together with the lifting frame 203. The telescopic discharge mechanism 206 can receive the plates sent out by the hydraulic press and transport the plates to the unloading conveyor belt 100.

[0027] This utility model, through the arrangement of a feeding conveyor belt 100, a discharge rack 201, a lifting cylinder 202, etc., adjusts the height of the discharge rack 201 and its telescopic discharge mechanism 206 by the lifting cylinder 202, so that it is aligned with the plates at different heights, and then lowers to the same height as the feeding conveyor belt 100. The telescopic discharge mechanism 206 transports the plates to the feeding conveyor belt 100 for discharge, thereby satisfying the stable discharge of plates of different heights. It has high flexibility, and only one telescopic discharge mechanism 206 is required to meet the stable feeding of plates of different heights.

[0028] To ensure the stability of the lifting of the discharge rack 201, limit rails 204 are installed on both sides of the discharge rack 201. A slider is provided on the limit rail 204. The slider can slide on the limit rail 204, and the cross section of the slider is set as T-shaped so that the slider cannot disengage from the limit rail 204. The limit rail 204 is set vertically to limit the movement trajectory of the slider. At the same time, the slider is fixedly connected to both ends of the lifting frame 203 to limit the movement path of the lifting frame 203 and ensure the stability of the lifting frame 203 and the lifting of the sheet metal.

[0029] In order to limit the conveying of the sheet material and ensure that the sheet material is stably conveyed to the unloading conveyor belt 100, limit plates 205 are provided on both sides of the lifting frame 203. The two limit plates 205 are arranged in parallel and fixed at both ends of the lifting frame 203 to limit the sheet material on the telescopic discharge mechanism 206 and prevent the sheet material from tilting during conveying.

[0030] Regarding the telescopic discharge mechanism 206, such as Figure 3 and Figure 4 As shown, the telescopic discharge mechanism 206 includes a fixed frame 2061, a first discharge cylinder 2062, a movable plate 2063, a second discharge cylinder 2064, and a feeding plate 2065. The fixed frame 2061 is mounted on the lifting frame 203, and connecting ears are provided on the side of the fixed frame 2061, which are connected to the lifting frame 203 by screws. The first discharge cylinder 2062 is installed at the bottom of the fixed frame 2061, and a sliding plate and a feeding plate 2065 are provided at the top of the fixed frame 2061. The movable plate 2063 and the feeding plate 2065 are both slidably mounted on the fixed frame 2061. The first discharge cylinder 2062... A connecting plate is provided at the outlet end, and the connecting plate extends upward through the fixed frame 2061 and connects with the movable plate 2063. A groove is opened on the fixed frame 2061 for the connecting plate to move. The movable plate 2063 is driven to move on the fixed frame 2061 by the first discharge cylinder 2062. A second discharge cylinder 2064 is installed on the movable plate 2063 and is connected to the feeding plate 2065. The second discharge cylinder 2064 drives the feeding plate 2065 to move on the movable frame. Both the first discharge cylinder 2062 and the second discharge cylinder 2064 can drive the plate to move from the hydraulic press to the unloading conveyor belt 100.

[0031] By setting the first discharge cylinder 2062 and the second discharge cylinder 2064 in the telescopic discharge mechanism 206, sufficient stroke is provided so that the feeding plate 2065 can approach the hydraulic plate and the unloading conveyor belt 100.

[0032] To ensure the stability of the conveyed sheet material, a first limiting groove 2066 is provided on the fixed frame 2061, and a movable plate 2063 is placed in the first limiting groove 2066, allowing the movable plate 2063 to slide within the first limiting groove 2066, thus limiting the movement of the movable plate 2063. Second limiting grooves 2067 are provided on both sides of the fixed frame 2061, and a feeding plate 2065 is placed on the second limiting grooves 2067, thus limiting the movement of the feeding plate 2065. Therefore, by limiting the movement of the movable plate 2063 and the feeding plate 2065, the stability of the sheet material conveying is improved.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
