Description

Technical Field

[0001] This utility model relates to the field of hydraulic processing, and in particular to a four-column hydraulic press with auxiliary feeding function. Background Technology

[0002] A four-column hydraulic press is a pressure processing device driven by a hydraulic system. Its main structure consists of four columns, an upper crossbeam, a lower crossbeam, and a movable crossbeam. It has high rigidity and stability. The movable crossbeam is driven up and down by a hydraulic cylinder, which can perform stamping, stretching, forming and other processing on workpieces such as metal sheets, plastics, and composite materials.

[0003] When hydraulically processing materials, the material is placed and then squeezed. After the squeezing is completed, the material is removed and then loaded again for processing. The repetitive operation of picking up and putting down the material makes the work efficiency too low and the use extremely inconvenient. At the same time, some materials will break and fly off due to the extrusion, which will greatly affect the safety of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a four-column hydraulic press with auxiliary feeding, thereby improving the ease of use of the device and enhancing the safety of hydraulic processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A four-column hydraulic press with auxiliary feeding function includes:

[0007] A bottom support platform for support, the top of which is fixedly connected to a support column frame, the bottom middle of which is fixedly connected to a hydraulic push rod, the output end of which is fixedly connected to a lower pressure plate, the rear end of which is fixedly connected to a connecting support platform, the top of which is fixedly connected to a material feeding frame, the top of which is slidably connected to a feeding push plate, and the rear end of which is connected to the rear side of the lower pressure plate through a flipping linkage component to facilitate material feeding.

[0008] A blocking and limiting frame for sliding inside the bottom support platform, wherein a first connecting seat is fixedly connected to both sides of the bottom end of the blocking and limiting frame, and a second connecting seat is fixedly connected to both sides of the bottom end of the bottom support platform. The interior of the second connecting seat is connected to the interior of the first connecting seat through a traction rod, so as to limit the splashing of crushed items.

[0009] Furthermore, the traction rod includes a flip frame that rotates inside the second connecting seat, and a flip plate is slidably connected inside the flip frame. The inner sides of the flip plate are respectively rotatably connected inside the first connecting seat.

[0010] Furthermore, the flipping linkage assembly includes fixed seats located on both sides of the rear end of the lower pressure plate. A traction connecting rod is rotatably connected inside the fixed seat. A push rod is fixedly connected to the rear end of the feeding push plate. Pulling slots are opened on both sides of the push rod. The bottom end of the traction connecting rod is rotatably connected to the inside of the pulling slot.

[0011] Furthermore, the outer side of the lower pressure plate is slidably connected to the outside of the column supporting the column frame.

[0012] Furthermore, the bottom end of the feeding frame is provided with a feeding slot to facilitate the feeding of materials.

[0013] Furthermore, the outer side of the flip plate is connected to the interior of the flip frame by multiple tension springs.

[0014] Furthermore, the blocking limit frame is U-shaped to improve the range of protection against compression.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the lower pressure plate pulls the connecting rod to flip, thereby pushing the rod backward and the material is separated from the top of the feeding push plate. The lower pressure plate then moves upward again to feed the material. The device can feed the material as it is pressed, further improving the convenience of using the device.

[0017] 2. In this utility model, the material is restricted by the blocking and limiting frame. The lower pressure plate presses downward, and the top of the blocking and limiting frame is attached to the bottom of the lower pressure plate by the tension generated by the flip plate and the tension spring, thereby restricting the material and preventing material fragments from flying out during the compression, thus improving the safety of the device in hydraulic processing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a four-column hydraulic press with auxiliary feeding, comprising: a bottom support platform 1 for support, a support column frame 2 fixedly connected to the top of the bottom support platform 1, a hydraulic push rod 4 fixedly connected to the middle of the bottom end of the support column frame 2, a lower pressure plate 3 fixedly connected to the output end of the hydraulic push rod 4, a connecting support platform 7 fixedly connected to the rear end of the bottom support platform 1, and a feeding frame 9 fixedly connected to the top of the connecting support platform 7. (Refer to...) Figure 6 A feeding push plate 17 is slidably connected to the top of the support platform 7. The rear end of the feeding push plate 17 is connected to the rear side of the lower pressure plate 3 through a flipping linkage assembly to facilitate material feeding. The flipping linkage assembly includes fixed seats 10 located on both sides of the rear end of the lower pressure plate 3. A traction rod 6 is rotatably connected inside the fixed seat 10. A push rod 8 is fixedly connected to the rear end of the feeding push plate 17. Pulling slots 18 are opened on both sides of the push rod 8. The bottom ends of the traction rod 6 are rotatably connected to the inside of the pull slots 18 respectively. The outer side of the lower pressure plate 3 is slidably connected to the outside of the column of the support column frame 2. A feeding slot 16 is opened at the bottom of the material feeding frame 9 to facilitate material feeding.

[0028] The feeding process of this hydraulic processing device is as follows: First, the raw material is piled in the feeding frame 9, allowing it to naturally accumulate on top of the feeding push plate 17. After starting the hydraulic push rod 4, the lower pressure plate 3 moves downward, causing the fixed seat 10 to move downward. This generates a downward thrust through the traction link 6, causing the traction link 6 to flip, which in turn pushes the push rod 8 backward, causing the feeding push plate 17 to move backward. At this time, the raw material slides from the top of the push plate to the predetermined position. After the hydraulic processing of the first piece of raw material is completed, the lower pressure plate 3 moves upward. Through the pulling force of the traction link 6, the feeding push plate 17 pushes the next piece of raw material to the processing position. This cycle repeats continuously, and the device can automatically and continuously feed materials according to the rhythm of hydraulic processing, significantly improving the ease of operation and work efficiency.

[0029] Reference Figure 2 , Figure 3 and Figure 4 A blocking and limiting frame 5 is used to slide inside the bottom support platform 1. The bottom ends of the blocking and limiting frame 5 are fixedly connected to the two sides of the bottom end of the first connecting seat 11. The bottom ends of the bottom support platform 1 are fixedly connected to the two sides of the bottom end of the second connecting seat 14. The interior of the second connecting seat 14 is connected to the interior of the first connecting seat 11 through a traction rod to limit the splashing of the crushed item. The traction rod includes a flipping frame 12 that rotates inside the second connecting seat 14. A flipping plate 13 is slidably connected inside the flipping frame 12. The inner side of the flipping plate 13 is rotatably connected to the interior of the first connecting seat 11 respectively. The outer side of the flipping plate 13 is connected to the interior of the flipping frame 12 through multiple tension springs 15. The blocking and limiting frame 5 is U-shaped to improve the range of protection against crushing.

[0030] The hydraulic device achieves safety protection through the blocking limit frame 5: after the material is placed inside the limit frame, the lower pressure plate 3 first presses down against the top of the limit frame, and then contacts the material to apply pressure. During the deformation of the material under pressure, the flying fragments are effectively intercepted by the blocking limit frame. At the same time, the lower pressure flipping frame 12 of the limit frame drives the flipping plate 13 to move outward, causing the tension spring 15 to deform and provide a continuous inward rebound force. This ensures that the top of the limit frame and the lower pressure plate 3 remain stably attached during the pressing process, and can automatically reset the flipping plate 13 by the spring tension after processing. This linkage design not only prevents fragments from flying but also ensures the safety of the entire hydraulic processing process.

[0031] Working principle: The raw materials to be hydraulically processed are piled into the inside of the feeding frame 9. At this time, the raw materials are piled on the top of the feeding push plate 17. When the material is pressed, the hydraulic push rod 4 is activated, pressing the lower pressure plate 3 downward, thereby pulling the fixed seat 10 downward, generating a downward thrust on the traction link 6, thereby generating a flipping force on the traction link 6, thereby generating a backward thrust on the push rod 8. The feeding push plate 17 moves backward, and the material is separated from the top surface of the feeding push plate 17 and located at the feeding slot 16. When the first piece of piled raw material is hydraulically processed, the lower pressure plate 3 moves upward, thereby generating a pulling force on the traction link 6, pushing the raw material outward through the feeding push plate 17, thereby reaching the position for hydraulic processing. Subsequently, the lower pressure plate 3 moves upward. The downward movement allows for continuous material feeding. The ejected material is located inside the blocking and limiting frame 5, which restricts the material. The downward pressure plate 3 presses against the top of the blocking and limiting frame 5, pressing it downwards and then into contact with the material. The material itself deforms due to pressure, and its external fragments fly outwards, blocked by the blocking and limiting frame 5, thus ensuring the safety of hydraulic processing. The downward pressure flipping frame 12 of the blocking and limiting frame 5 flips accordingly, and the flipping plate 13 moves outwards, causing the tension spring 15 to deform and generate an inward pulling force on the flipping plate 13. The top of the blocking and limiting frame 5 is stably attached to the bottom of the downward pressure plate 3, ensuring stability. After the hydraulic processing is completed, the blocking and limiting frame 5 will be reset by the pull of the flipping plate 13 due to the tension generated by the tension spring 15.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
