Description

Technical Field

[0001] The utility model relates to the technical field of pre-pressing devices, in particular to a novel pre-pressing device for a hydraulic gate-type shearing machine. Background Art

[0002] Shearing machine is a machine that shears plates by reciprocating linear motion of one blade relative to another blade. It applies shearing force to metal plates of various thicknesses by using a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap, so that the plates are broken and separated according to the required size. In order to make the plate flatness meet the requirements when the shearing machine is working, it is usually necessary to pre-press the plate through a pre-pressing device.

[0003] Before sending the steel plate into the shearing machine for processing, the steel plate needs to be straightened by a pre-pressing device. After the existing pre-pressing device straightens the steel plate, the steel plate will stick to the workbench of the pre-pressing device, making it difficult to remove it, and it is inconvenient to unload the processed steel plate, which affects the processing efficiency of the pre-pressing device.

[0013] Compared with the prior art, the novel hydraulic gate shearing machine pre-pressing device has the following beneficial effects: the worker can stand on the pressure plate body, and the pressure plate body will move downward under the force and squeeze the spring. When the pressure plate body moves downward, it will mesh with the driving gear, and the driving gear can drive the first synchronous wheel to rotate. The first synchronous wheel can drive the second synchronous wheel to rotate through the synchronous belt, and the second synchronous wheel can transmit the force to the driven gear, so that it can rotate synchronously with the driving gear in the same direction. When the driving gear rotates, it will mesh with the push rod to move it upward, and when the push rod moves upward, it can lift the top steel plate, which can facilitate the worker to take the steel plate and move it out.

[0014] 1. Before sending the steel plate into the shearing machine for processing, the steel plate needs to be straightened by the pre-pressing device.

The first synchronous wheel can drive the second synchronous wheel to rotate through the synchronous belt. The second synchronous wheel can transmit the force to the driven gear, so that it rotates synchronously with the driving gear in the same direction. When the driving gear rotates, it will mesh with the push rod to move it upward. When the push rod moves upward, the top steel plate can be lifted up, which makes it convenient for the staff to take the steel plate and move it out. In this way, the above operation can facilitate the removal of the processed steel plate on the machine body.

[0015] 2. Before sending the steel plate into the shearing machine for processing, the steel plate needs to be straightened by the pre-pressing device. By pulling the pull rod, the pull rod will mesh with the first large gear to make it rotate, and the first large gear will mesh with the small gear to drive it to reverse. When the small gear rotates, it will drive the second large gear to mesh with the rack rod, so that the rack rod drives the cleaning rod to move on the table of the machine body. Since the number of teeth of the first large gear is greater than that of the small gear, the small gear can rotate multiple circles when the first large gear rotates one circle, and the small gear can drive the second large gear to rotate multiple circles, so that the rack rod moves quickly, so that the pull rod only needs to move a short distance to drive the rack rod to clean the machine body. In this way, the above operation can facilitate the cleaning of the processing table of the machine body and facilitate the pre-pressing work. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In specific implementation, before the steel plate is sent into the shearing machine for processing, it is necessary to straighten the steel plate through the pre-pressing device. When taking out the steel plate on the pre-pressing device, the staff can stand on the pressure plate body 5, and the pressure plate body 5 will move downward under the force and squeeze the spring 6. When the pressure plate body 5 moves downward, it will mesh with the driving gear 7, and the driving gear 7 can drive the first synchronous wheel 8 to rotate. The first synchronous wheel 8 can drive the second synchronous wheel 10 to rotate through the synchronous belt 9, and the second synchronous wheel 10 can transmit the force to the driven gear 11, so that it can rotate synchronously with the driving gear 7 in the same direction. When the driving gear 7 rotates, it will mesh with the push rod 12 to move it upward. When the push rod 12 moves upward, it can lift the top steel plate, which is convenient for the staff to take the steel plate and move it out to complete the unloading. After the staff leaves the pressure plate body 5, the spring 6 will reset and push the pressure plate body 5 to reset. After losing the extrusion force, the push rod 12 will also move downward under the action of gravity and enter the interior of the machine body 1. At this time, the next group of steel plates can be placed on the machine body 1 for processing. In this way, the above operation can facilitate the removal of the processed steel plates on the machine body 1.

[0026] In specific implementation, before the steel plate is sent to the shearing machine for processing, it is necessary to use a pre-pressing device to straighten the steel plate. When the steel plate is placed on the workbench of the pre-pressing device for processing, it is necessary to ensure that there is no debris on the table of the pre-pressing device to prevent debris from being embedded in the bottom of the steel plate during the straightening process. In order to facilitate the cleaning of the table of the pre-pressing device, by pulling the pull rod 13, the pull rod 13 will mesh with the first large gear 14 to make it rotate, and the first large gear 14 will mesh with the small gear 15 to drive it to reverse. When the small gear 15 rotates, it will drive the second large gear 20 to mesh with the rack rod 16, so that the rack rod 16 drives the cleaning rod 17 to move on the table of the machine body 1. The number of teeth of gear 14 is greater than that of pinion 15. Therefore, when the first large gear 14 rotates one circle, the pinion 15 can rotate multiple circles. The pinion 15 can also drive the second large gear 20 to rotate multiple circles, so that the rack rod 16 moves quickly, so that the pull rod 13 only needs to move a short distance to drive the rack rod 16 to clean the machine body 1. By pulling the pull rod 13 to drive the cleaning rod 17 to move back and forth once on the table of the machine body 1, the debris on the processing position on the table of the machine body 1 can be removed, and then the steel plate can be processed. The sliding rod 19 can guide and limit the cleaning rod 17 to ensure the smooth movement of the cleaning rod 17. In this way, the above operation can facilitate the cleaning of the processing table of the machine body 1 and facilitate the pre-pressing work.

[0027] To sum up: when using the new hydraulic gate shearing machine pre-pressing device, first place the steel plate on the processing table of the machine body 1, and then start the hydraulic rod 2 to drive the pre-pressing plate 3 to move downward. After the pre-pressing plate 3 contacts the steel plate, it can be straightened. This is the feature of the new hydraulic gate shearing machine pre-pressing device.
