Description

Technical Field

[0001] This utility model belongs to the field of press technology, specifically relating to a semi-closed press frame. Background Technology

[0002] In modern manufacturing, press frames are essential equipment for stamping, forming, and other processing. Traditional press frames typically consist of a fixed module and a moving module. The fixed module is mounted on a platform, while the moving module is assembled onto a vertical frame via a crankshaft pressure mechanism. While this structure meets basic processing requirements, it has some shortcomings in practical use.

[0003] 1. Inconvenient replacement and maintenance of fixed molds: In traditional press frames, the fixed mold assembly is usually fixedly mounted on the platform. Replacement or maintenance requires disassembling multiple parts, which is complex and time-consuming. This not only increases downtime but may also lead to a decrease in production efficiency.

[0004] 2. Difficulty in replacing and maintaining the moving module: The moving module is assembled on the upright frame via a crankshaft pressure mechanism, and its position is relatively fixed. When it is necessary to replace or maintain the moving module, due to the lack of convenient operating space, operators often need to disassemble multiple connecting parts, and may even need to move the entire upright frame. This not only increases the difficulty of the work, but may also cause unnecessary damage to the equipment.

[0005] Therefore, based on some of the situations in the prior art described above, this application has made further designs and improvements. Utility Model Content

[0006] To address the aforementioned technical problems, this invention provides a semi-enclosed press frame that is structurally sound, functionally comprehensive, and easy to maintain. Its unique sliding fixed mold installation method, combined with a flexible and versatile moving mold replacement scheme, simplifies the replacement process for both the moving and fixed molds, improves maintenance efficiency, and is highly suitable for various industrial scenarios requiring frequent mold changes.

[0007] Specifically, a semi-closed press frame has a platform for mounting a fixed module and a vertical frame for mounting a moving module. The moving module is assembled on the vertical frame via a crankshaft pressure mechanism. The platform has a sliding groove, in which the fixed module is mounted and can slide back and forth. Several first fixing pins are mounted on both sides of the sliding groove, and the fixed module has first fixing holes that mate with the first fixing pins. This design allows the fixed module to be easily moved out from under the moving module, greatly simplifying the process of replacing and maintaining the fixed module. The vertical frame has a guide channel for lifting and guiding the moving module. The outer wall of the guide channel is a guide limiting plate, which is movable. By moving the guide limiting plate, the guide channel can be opened, allowing the moving module to be flipped outwards, greatly facilitating the replacement and maintenance of the moving module.

[0008] In a preferred embodiment of a semi-closed press frame, the guide limiting plate is hinged to the upright frame, the upright frame is equipped with a second fixing pin, and the guide limiting plate is provided with a second fixing hole that mates with the second fixing pin. This design allows the guide limiting plate to rotate open or close relative to the upright frame. When the moving mold needs to be replaced or repaired, the guide limiting plate can be opened by unlocking the second fixing pin, allowing the moving mold to be flipped outward, greatly facilitating the operator's work and improving safety.

[0009] In a preferred embodiment of a semi-closed press frame, a lifting guide rail is mounted on the upright section, and the guide limiting plate is slidably assembled with the lifting guide rail. This design opens the guide channel through the lifting guide limiting plate, allowing the moving module to flip outward, facilitating the replacement and maintenance of the moving mold.

[0010] In a preferred embodiment of a semi-enclosed press frame, first cleaning grooves are provided on the two side walls near the inner side of the slide. These first cleaning grooves facilitate the removal of debris or other impurities accumulated inside the slide, maintaining its cleanliness and extending the equipment's service life.

[0011] In a preferred embodiment of a semi-enclosed press frame, a second cleaning groove is provided on the outer side of the slide groove, the width of the second cleaning groove being smaller than the width of the slide groove. The second cleaning groove facilitates the removal of debris or other impurities accumulated on the outer side of the slide groove, keeping the inside of the slide groove clean and extending the service life of the equipment.

[0012] Compared with the prior art, this application has the following advantages: it greatly facilitates the replacement and maintenance of the fixed mold and the moving mold, and reduces downtime and operational complexity. Attached Figure Description

[0023] A semi-enclosed press frame includes a platform section 10 for mounting a fixed module 11 and a vertical frame section 20 for mounting a moving module 21. The moving module 21 is mounted on the vertical frame section 20 via a crankshaft pressure mechanism 22. A sliding groove 12 is provided on the platform section 10, and the fixed module 11 is mounted within the sliding groove 12 and can slide back and forth along the groove 12. Several first fixing pins 13 are mounted on both sides of the sliding groove 12, and the fixed module 11 has first fixing holes that mate with the first fixing pins 13. This design allows the fixed module 11 to be easily moved out from under the moving module 21, greatly simplifying the process of fixed module replacement and maintenance. A guide channel 23 is provided within the vertical frame section 20 for guiding the moving module 21 in lifting and lowering. The outer wall of the guide channel 23 is a guide limiting plate 24, which is movable. The guide channel 23 can be opened by moving the guide limit plate 24, which allows the moving module 21 to be flipped outward, greatly facilitating the replacement and maintenance of the moving module.

[0024] To prevent impurities or oil stains generated during processing from remaining inside the slide groove 12 and affecting the sliding of the fixed mold base, first cleaning grooves 14 are provided on the two side walls of the slide groove 12 near the inner side. The first cleaning grooves 14 facilitate the removal of debris or other impurities accumulated inside the slide groove 12, keeping the interior of the slide groove 12 clean and extending the service life of the equipment. A second cleaning groove 15 is provided on the outer side of the slide groove 12, the width of which is smaller than the width of the slide groove 12. The second cleaning groove 15 facilitates the removal of debris or other impurities accumulated on the outer side of the slide groove 12, keeping the interior of the slide groove 12 clean and extending the service life of the equipment.

[0025] As one embodiment of this application (Embodiment 1), refer to Figure 1 and Figure 2 The guide limiting plate 24 is hinged to the upright portion 20. A second fixing pin 25 is mounted on the upright portion 20, and the guide limiting plate 24 has a second fixing hole that mates with the second fixing pin 25. This design allows the guide limiting plate 24 to rotate open or close relative to the upright portion 20. When the moving mold needs to be replaced or repaired, the guide limiting plate 24 can be opened by unlocking the second fixing pin 25, allowing the moving module 21 to flip outwards. This greatly facilitates the operator's work and improves safety.

[0026] As another embodiment of this application (Embodiment 2), refer to Figure 3 and Figure 4 The upright frame 20 is equipped with a lifting guide rail 26, and the guide limiting plate 24 is slidably assembled with the lifting guide rail 26. This design opens the guide channel 23 through the lifting guide limiting plate 24, thereby allowing the moving module 21 to be flipped outward, which facilitates the replacement and maintenance of the moving module.

[0027] To ensure smooth sliding of the fixed module 11 within the slide groove 12, and considering wear during long-term use and resistance to impurities, the bottom of the fixed module 11 (the part in direct contact with the slide groove 12) is treated with surface hardening techniques such as carburizing and nitriding. This not only improves surface hardness and enhances wear resistance but also maintains the good toughness of the internal materials. Alternatively, a special coating or plating, such as a PTFE (polytetrafluoroethylene) coating, can be applied to the bottom of the fixed module 11. This material has an extremely low coefficient of friction and excellent corrosion resistance, effectively reducing friction during sliding and preventing chemical corrosion. Furthermore, the surface of the slide groove 12 is made of a more wear-resistant metal alloy or its surface hardness is increased through heat treatment to extend its service life. These surface treatments for the fixed module 11 and the slide groove 12 significantly improve the overall performance and reliability of the equipment, greatly extend its service life, and reduce maintenance costs.
