Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic press accessories, and in particular to a material pushing component for a heavy-duty hydraulic press. Background Technology

[0002] A hydraulic press is a machine that uses liquid as its working medium and is designed based on Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the press itself, a power system, and a hydraulic control system. Currently, feeding and pushing materials in existing hydraulic presses are done manually, which is time-consuming and prone to accidents. This necessitates a material pushing component for heavy-duty hydraulic presses. This component is a mechanical device used to automatically, stably, and efficiently push materials to the working area of ​​the hydraulic press. Its core function is to replace manual operation, achieving precise material positioning and continuous supply, especially in the high-pressure, high-tonnage operating environment of heavy-duty hydraulic presses, ensuring operational safety and production efficiency.

[0003] To this end, Chinese patent application CN215152254U discloses a material pushing device for a hydraulic press, including a base platform, a hydraulic press, and a feeding device. The base platform has a worktable at its top that cooperates with the hydraulic press. One end of the worktable has an electric push rod, the front end of which is connected to a push plate. A brush is connected to the bottom of the push plate, and suction pipes are provided at both ends of the push plate. A material box and a vacuum pump are installed at the top of the push plate. The suction port of the vacuum pump is connected to the material box, and the material box is connected to the suction pipes via a pipe. The advantages of this invention compared to existing technologies are: automatic material pushing and unloading, convenient cleaning of the operating platform, improved work efficiency, and guaranteed operator safety.

[0004] The aforementioned material pushing device for hydraulic presses aims to achieve automatic material pushing and unloading, facilitate cleaning of the operating platform, improve work efficiency, and ensure operator safety. However, during use, the product positioning is not stable enough when pushing material, and wobbling may occur during movement, leading to product derailment. Utility Model Content

[0005] The purpose of this invention is to provide a material pushing component for heavy-duty hydraulic presses, which solves the problem that existing material pushing components for heavy-duty hydraulic presses are difficult to position products.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a material pushing component for a heavy-duty hydraulic press, including a housing;

[0007] The bottom of the box is equipped with support legs, the top of the box is equipped with a workbench, and a fixing plate is installed on one side of the top of the workbench.

[0008] An electric push rod is installed at one end of the fixed plate, and a push plate is installed on one side of the electric push rod. Both ends of the top of the worktable are equipped with baffles, and a positioning structure is installed at the top of the worktable.

[0009] The positioning structure includes a mounting frame installed at the top of the workbench, a first telescopic rod installed at the top of the mounting frame, a second telescopic rod installed at the bottom of the first telescopic rod, and a pressure plate installed at the bottom of the second telescopic rod.

[0010] In use, the electric push rod first drives the push plate to move, and the push plate moves the product. The product can move inside the baffle. The push plate will push the product to the bottom of the hydraulic press for processing. The guide rod on one side of the push plate passes through the guide block. The guide wheel and guide rod inside the guide block pass through the sliding structure. The guide block and guide rod work together to guide the push plate and prevent the push plate from deviating.

[0011] Furthermore, guide structures are installed at both ends of the fixed plate, and the guide structure includes a guide rod installed at one end of the push plate, a guide block installed on one side of the fixed plate, and a guide wheel installed inside the guide block. The guide structure can guide the push plate.

[0012] Furthermore, the outer diameter of the guide rod is smaller than the inner diameter of the guide block, and the guide rod and the guide block form a sliding structure, so that the guide rod can guide the push plate.

[0013] Furthermore, a positioning rod is installed at the top of the pressure plate, and the positioning rod is symmetrically distributed about the central axis of the pressure plate, so that the positioning rod can guide the pressure plate.

[0014] Furthermore, a spring is installed at the top of the second telescopic rod, and the spring and the second telescopic rod form an elastic connection, with the spring being elastic.

[0015] Furthermore, a limiting structure is installed on one side of the workbench, and the limiting structure includes a limiting plate installed on one side of the top of the workbench, a moving block installed at the bottom of the limiting plate, and a threaded rod passing through the inside of the moving block. A servo motor is installed at one end of the threaded rod, and connecting rods pass through both ends of the moving block. The limiting structure can limit the product.

[0016] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the moving block is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the moving block are threadedly connected, and the movement of the threaded rod will drive the moving block to move.

[0017] The material pushing component for heavy-duty hydraulic presses provided by this utility model has the following advantages: the product can be positioned by the positioning structure to prevent the product from shaking when moving; the product can be limited and fixed by the limiting structure; and the push plate can be guided by the guiding structure.

[0018] A mounting bracket is installed at the top of the workbench, and the mounting bracket and the pressure plate are connected by a first telescopic rod and a second telescopic rod. The first and second telescopic rods form a sliding structure. The springs inside the first and second telescopic rods are elastic. The elasticity of the springs will cause the second telescopic rod to descend. The descent of the second telescopic rod can cause the pressure plate to press against the top of the product. When the product moves, the pressure plate can position the product to prevent it from shifting. The positioning rod can extend and retract, and the positioning rod can prevent the pressure plate from shifting. This achieves the purpose of facilitating product positioning in the material pushing component of the heavy-duty hydraulic press.

[0019] By installing a limit plate on one side inside the worktable, the moving block and threaded rod at the bottom of the limit plate form a threaded connection. When the servo motor works, it drives the threaded rod to rotate, which in turn drives the moving block to move. Since the threads on the threaded rod are symmetrically distributed about the central axis of the threaded rod, the movement of the moving block will drive the limit plate to move in the opposite direction. The movement of the limit plate can limit the product pushed to the limit plate position, so that the product will not deviate during hydraulic processing. The connecting rod passes through the moving block and can guide the movement of the moving block, thereby achieving the purpose of facilitating the limiting of the product in the material pushing component of the heavy-duty hydraulic press.

[0030] See attached document Figure 1-4 As shown, the movable block 703 at the bottom of the limiting plate 701 and the threaded rod 705 form a threaded connection. The operation of the servo motor 702 will drive the threaded rod 705 to rotate. The rotation of the threaded rod 705 will drive the movable block 703 to move. Since the threads on the threaded rod 705 are symmetrically distributed about the central axis of the threaded rod 705, the movement of the movable block 703 will drive the limiting plate 701 to move in the opposite direction. The movement of the limiting plate 701 can limit the product pushed to the position of the limiting plate 701, so that the product will not deviate during hydraulic processing. The connecting rod 704 passes through the movable block 703 and can guide the movement of the movable block 703.

[0031] A fixed plate 2 is installed on one side of the top of the workbench 1. Guide structures 10 are installed on both ends of the fixed plate 2.

[0033] See attached document Figure 1 and attached Figure 5 As shown, the operation of the electric push rod 3 will drive the push plate 4 to move, and the movement of the push plate 4 will push the product to move. The product can move inside the baffle 9. The movement of the push plate 4 will push the product to the bottom of the hydraulic press for processing. The guide rod 1001 on one side of the push plate 4 passes through the guide block 1002. The guide wheel 1003 inside the guide block 1002 and the guide rod 1001 pass through the sliding structure. The guide block 1002 and the guide rod 1001 cooperate to guide the push plate 4 and prevent the push plate 4 from deviating.

The first telescopic rod 805 and the second telescopic rod 806 form a sliding structure. The spring 804 inside the first telescopic rod 805 and the second telescopic rod 806 is elastic. The elasticity of the spring 804 will drive the second telescopic rod 806 to descend. The descent of the second telescopic rod 806 can drive the pressure plate 802 to press against the top of the product. When the product moves, the pressure plate 802 can position the product to prevent the product from deviating. The positioning rod 803 can extend and retract, and the positioning rod 803 can prevent the pressure plate 802 from deviating.
