Description

Technical Field

[0001] This utility model relates to the field of pressure equipment technology, specifically a pressure device with protective and cleaning functions. Background Technology

[0002] Pressure devices (such as stamping presses, presses, and forging presses) are widely used in industrial fields such as metal forming, material processing, and parts assembly. Their core working principle is to apply enormous pressure to the workpiece through a pressure head to achieve plastic deformation, blanking, stamping, or joining. However, during processing, especially during blanking, forging, or material fracture, high-speed flying debris (such as metal shavings, plastic residue, dust, etc.) and broken workpiece fragments are inevitably generated. These flying debris and fragments not only pollute the working environment but also pose serious safety threats to operators (such as cuts and eye injuries) and may damage equipment or affect product processing accuracy.

[0003] To address the aforementioned risks, existing technologies commonly employ fixed or hinged protective devices. These include fixed protective covers and hinged protective covers.

[0004] Fixed protective covers: These covers are typically installed around the working area of ​​the pressure device, forming a fixed, enclosed or semi-enclosed space. Their advantages include simple structure and reliable protection. However, their biggest drawback is the severe restriction of operating space. When loading (placing workpieces to be processed) and unloading (removing finished workpieces or scrap), operators must operate through narrow openings, making movements extremely inconvenient and inefficient, especially for larger or more complex-shaped workpieces. Furthermore, cleaning accumulated debris inside the cover becomes exceptionally difficult. Operators usually need to stop the machine and laboriously reach inside with long-handled tools to clean, or disassemble parts of the protective structure for thorough cleaning. This is not only time-consuming and labor-intensive, increasing equipment downtime and indirectly raising maintenance costs, but also carries the risk of injury from residual debris during the cleaning process.

[0005] Openable protective covers: These covers typically include an openable door. The door is opened for loading / unloading and closed for protection during processing. Compared to fixed covers, this improves the operating space to some extent. However, the operating space is still limited by the door's size and opening angle. For large workpieces or loading / unloading processes requiring delicate handling, it remains inconvenient. Furthermore, each operation requires a "door-operation-door-closing" cycle, increasing operational steps and waiting time, thus impacting efficiency. Additionally, cleaning is also difficult. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, this utility model provides a pressure device with protective and cleaning functions. The protective cover moves with the horizontal plate and the pressure head, descending to the worktable for protection during operation and rising to create space when not in operation, facilitating loading and unloading of materials and improving operational convenience and efficiency. The protective cover assembly is connected to the cleaning assembly. After the work is completed, a blower blows the debris to the filter screen, which can be pulled out for cleaning, making cleaning convenient, quick, and safe.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A pressure device with protective and cleaning functions includes a worktable, a horizontal plate, a hydraulic cylinder, a protective cover, a pressure head, a blower, and a cleaning assembly.

The end is fixedly connected to the center of the upper surface of the horizontal plate 17. Fixed plates 19 are respectively provided on both sides of the center of the lower bottom surface of the horizontal plate 17. The protective cover 20 is vertically slidably connected to the pair of fixed plates 19 via a sliding assembly. A pressure head 16 is fixedly provided at the center of the lower bottom surface of the horizontal plate 17. An opening 13 is provided at the center of the top of the protective cover 20, through which the pressure head 16 vertically moves. An opening 7 is provided at the center of the lower bottom surface of the protective cover 20. The upper surface of the workbench 6 and the... A mold platform 5 is fixedly installed directly below the opening 7. The size of the opening 7 is larger than that of the mold platform 5. A cleaning component is installed on one side of the upper surface of the workbench 6. The cleaning component includes a blower 1 and a flexible air duct 2. The blower 1 is fixedly installed on the workbench 6. A connector 21 is installed on the side surface of the protective cover 20. One end of the flexible air duct 2 is connected to the air outlet of the blower 1, and the other end is connected to the connector 21. An installation groove 8 is opened inside the protective cover 20 on the side away from the connector 21. A filter screen 10 is inserted into the installation groove 8. Multiple air holes 9 are evenly opened on the side surface of the protective cover 20 corresponding to the position of the filter screen 10. The sliding component includes a slider 11. A sliding groove 12 is vertically opened on the inner side wall of the fixed plate 19. The slider 11 is fixedly installed on the upper edge of the side surface of the protective cover 20 and corresponds to the sliding groove 12. The slider 11 and the sliding groove 12 are slidably connected. A compression spring 18 is installed between the upper ends of the slider 11 and the sliding groove 12. A rubber pad 4 is installed on the workbench 6.

[0018] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0019] According to the instruction manual Figure 1As can be seen, when this utility model is working, the hydraulic cylinder 15 drives the horizontal plate 17 to move upward, thereby driving the fixed plate 19, the pressure head 16, and the protective cover 20 to move upward, away from the worktable 6 and the mold table 5. The operator installs the material to be pressure operated on the mold table 5. Here, existing clamps can also be used to assist in clamping the material, as long as it does not affect the processing. The connection between the hydraulic cylinder 15 and the external hydraulic station is existing technology, which can be understood by those skilled in the art. After the material is installed, the hydraulic cylinder 15 works, driving the horizontal plate 17, the pressure head 16, the fixed plate 19, and the protective cover 20 to move downward. The opening 7 of the protective cover 20 is larger than the mold table 5. The bottom of the protective cover 20 contacts the worktable 6 first to ensure a certain seal. Since the protective cover 20 and the fixed plate 19 are connected by a sliding component, as the pressure continues to be applied, the protective cover 20 and the fixed plate 19 move relative to each other, and the pressure head 16 applies pressure to the material. The protective cover 20 can prevent debris from flying during the pressure operation. After the operation is completed, blower 1 blows strong air into the protective cover 20 through flexible air duct 2 and connector 21. The airflow should be strong enough to direct the pressure generated inside the protective cover 20 and on the mold table 5 onto the filter screen 10 on the other side. The filter screen 10 corresponds to the air hole 9 to ensure the normal operation of the blow-cleaning process. Residue is filtered and left on the filter screen 10, which can be pulled out from the mounting slot 8 of the protective cover 20 for cleaning. Regular cleaning is sufficient; it does not need to be cleaned every time. An openable door can be installed in the mounting slot 8 on the front side wall of the protective cover 20, allowing for the installation and removal of the filter screen 10 while ensuring a certain degree of sealing. This method is well implemented using existing technology. After cleaning, the extension end of the hydraulic cylinder 15 rises to remove the material after the pressure operation. The protective cover 20 of this utility model moves with the horizontal plate 17 and the pressure head 16. When working, it descends to the worktable 6 for protection, and when not working, it rises to free up space, making it convenient to load and unload materials, thus improving the convenience and efficiency of operation. The protective cover 20 component is connected to the cleaning component. After the work is completed, the blower 1 blows the debris to the filter screen 10, which can be pulled out for cleaning. The cleaning is convenient, quick and safe.

[0020] The sliding assembly includes a slider 11. A vertical groove 12 is provided on the inner side wall of the fixed plate 19. The slider 11 is fixedly installed on the upper edge of the side surface of the protective cover 20 and corresponds to the groove 12. The slider 11 and the groove 12 are slidably connected to ensure the stability of the vertical movement of the protective cover 20. A compression spring 18 is provided between the upper end of the slider 11 and the groove 12. The force of the compression spring 18 makes the protective cover 20 fit tightly against the worktable 6 to ensure the protective effect.

[0021] Among them, a rubber pad 4 is provided on the workbench 6. The rubber pad 4 has a certain buffering and shock absorption effect, reducing the vibration of the protective cover 20 on the workbench 6.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
