Description

Technical Field

[0001] This utility model belongs to the technical field of mold changing equipment, and more specifically, relates to a quick mold changing device applicable to multiple types of molds. Background Technology

[0002] In the forging industry, dies, as the core components for forming forgings, need to be replaced periodically according to the specifications and shape requirements of different forging products. The efficiency and safety of die replacement directly determine the overall capacity, production safety, and operating costs of the forging production line. Currently, most forging enterprises in China generally adopt two mainstream methods for online die replacement operations (i.e., die replacement operations when the forging equipment is in the production position): traditional manual handling or gantry crane "tilting and lifting at an angle" to send the die to be replaced into or pull it out of the die holder. This type of die replacement scenario is widespread in various forging production lines, including free forging and die forging, involving multiple sub-sectors such as automotive parts forging, engineering machinery parts forging, and aerospace precision forging manufacturing. It is a key process link that forging enterprises cannot avoid in achieving continuous production. With the increasing market demand for diversified forging products, the frequency of die replacement in forging production is further increasing. However, the problems exposed by traditional die replacement methods are becoming increasingly prominent, becoming a major bottleneck restricting forging enterprises from improving production efficiency, reducing safety risks, and controlling production costs.

[0003] To address the inefficiencies and safety issues inherent in traditional die-changing methods, existing technological efforts have explored improvements aimed at enhancing the convenience and safety of forging die replacement by optimizing the die-changing device and operational procedures. Specialized die-changing trolley technology is gradually emerging in the industry. These trolleys are typically equipped with rollers, lifting mechanisms, and positioning components. During use, the die to be replaced is placed on the trolley, which moves to transport the die to the bottom or side of the die holder. The lifting mechanism then precisely aligns the die with the installation position on the die holder, completing the die insertion or removal operation. Furthermore, some die-changing trolleys are designed with interfaces compatible with forging equipment, enabling collaborative operation between the trolley and the equipment. This further reduces manual intervention, attempting to replace traditional manual handling and simple gantry crane hoisting with mechanized and automated methods, thereby improving die-changing efficiency and reducing labor intensity.

[0004] Although existing technologies have proposed improvements to address the problem of die changing in forging, they still cannot fundamentally solve core issues such as low efficiency, significant safety hazards, and large space requirements. For example, while specialized die-changing trolley technology can achieve ground movement and precise docking of dies, significantly reducing the risks of working at heights, this technology has a serious space-consuming drawback—the die-changing trolley needs to be parked near the forging equipment for extended periods to ensure quick access during die-changing operations. However, the trolley itself has a certain volume (depending on the die size, the trolley is typically 2-5 meters long and 1-2 meters wide), and long-term parking will occupy significant space. Valuable production space within the factory, especially for small and medium-sized forging enterprises with compact production workshop layouts, is at risk. The presence of die-changing trolleys can encroach on workpiece storage areas, personnel passageways, or the operating space of other equipment. This not only affects the cleanliness and convenience of the production site but may also lead to new safety hazards due to overcrowding. Furthermore, some die-changing trolleys require complex adaptation and debugging with forging equipment, resulting in high debugging costs. Different specifications of dies require different models of die-changing trolleys, forcing enterprises to invest more funds in purchasing multiple trolleys, increasing production costs and ultimately weakening the enterprise's market competitiveness.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please refer to Figures 1 to 3 This utility model provides a quick mold changing device applicable to multiple types of molds, including: guide rail 5, walking side beam 6, driving component 7, driving wheel 8, driven wheel 9, lifting cylinder 11, lifting support 12 and raising component 14; The guide rail 5 is made of I-beams and is horizontally set. One end is fixed to the upper end of the fuselage base 2, and the lower flange and web plate of the other end are embedded in the working ground. The two guide rails 5 are arranged in a mirror symmetrical manner with respect to the central axis of the mold pad 3 on the fuselage base 2. The traveling side beam 6 is mounted above the guide rail 5 via the drive wheel 8 and several driven wheels 9; the drive wheel 8 is located within a square mounting frame 601 on the front side of the traveling side beam 6 and is slidably connected to the guide rail 5; several driven wheels 9 are located inside the traveling side beam 6 along the extension direction of the guide rail 5 and are slidably connected to the guide rail 5; the output end of the drive component 7 is connected to the drive wheel 8 and is used to drive the traveling side beam 6 to reciprocate on the guide rail 5; Multiple lifting cylinders 11 are located on the upper end of the machine base 2 and close to the mold pad 3. Multiple lifting supports 12 are respectively located on the front and rear sides of the lower mold base 4, and the lifting cylinders 11 and the lifting supports 12 correspond one-to-one. The movable end of the lifting cylinder 11 is located below the lifting support 12 and is used to lift the lower mold base 4 to disengage from the positioning key on the upper end of the mold pad 3. Several of the aforementioned shim components 14 are respectively disposed on the upper end of the traveling side beam 6 and the mounting frame 601, and are used to insert into the gap between the lower mold base 4 and the traveling side beam 6 after the lower mold base 4 rises, so as to avoid the lower mold base 4 colliding with the mold pad 3 during the mold changing process.

[0024] During use, guide rails 5 are made of I-beams and set horizontally, with one end fixed to the upper end of the fuselage base 2, and the other end's lower flange and web plate pre-embedded in the working ground. This effectively absorbs vibration and impact during operation. Furthermore, the two guide rails 5 are arranged in a mirror-symmetrical manner around the central axis of the mold pad 3, ensuring the balance and guiding accuracy of the walking system. Secondly, the walking side beam 6 is slidably connected to the guide rails 5 through the front drive wheel 8 and multiple driven wheels 9 inside, forming stable support and smooth movement. At the same time, the output shaft of the drive component 7 is fixedly connected to the drive wheel 8. The walking side beam 6 can be precisely controlled to reciprocate along the extension direction of the guide rail 5, so as to realize the automatic entry and exit of the lower mold base 4 into and out of the machine body base 2. In addition, the lifting cylinder 11 is located on the upper end of the machine body base 2 and close to the mold pad 3. Its movable end acts on the lifting support 12 located on the front and rear sides of the upper mold base 4. Through synchronous lifting action, the lower mold base 4 is smoothly disengaged from the positioning key on the mold pad 3, avoiding damage caused by forced dragging. At the same time, the shim component 14 can be inserted into the gap between the lower mold base 4 and the walking side beam 6 after the lower mold base 4 is lifted to realize the support transition and ensure the safety and reliability of the mold changing process.

[0025] It is understood that the mold changing device can complete the replacement of various types of molds at the forging station by transferring the lower mold support of the mold; the bottom of the machine base 2 is also embedded in the working ground to ensure the stability of the entire device and the level of the guide rail 5.

[0026] In an optional embodiment, the two mounting frames 601 are fixedly connected by a square tube 602, and the driving component 7 is fixedly connected to the square tube 602. This is used to effectively ensure the structural rigidity and installation coaxiality of the mounting frames 601 on both sides, so that the power of the driving component 7 is evenly transmitted to the driving wheel 8, ensuring that the walking side beams 6 on both sides run synchronously on the guide rail 5, avoiding jamming, vibration or wear caused by uneven load or asynchrony, and improving the stability and reliability of the mold changing device.

[0027] It should be noted that the driving component 7 described in this embodiment is a common driving component in the prior art, such as a drive motor and a reducer. In other embodiments, other types of driving components may also be used, as long as they can ensure that the drive wheel 8 runs smoothly and accurately on the guide rail 5 and provide sufficient driving force to support the weight of the lower mold base 4. No specific limitation is made here.

[0028] In an optional embodiment, the driven wheel 9 is a single-rimmed wheel, and the rim height is less than the height of the upper flange plate of the guide rail 5. This is used to effectively prevent the wheel from derailing during operation, while avoiding interference between the rim and the upper flange plate of the guide rail 5, ensuring that the traveling side beam 6 slides smoothly along the guide rail 5, and improving the guiding reliability and smooth operation of the mold changing process.

[0029] In an optional embodiment, the traveling side beam 6 does not contact the lower die base 4, and the height difference between the upper surface of the traveling side beam 6 and the lower surface of the lower die base 4 directly above it is 5mm to 25mm. This is to effectively avoid interference or collision between the two caused by equipment vibration or die sinking during the forging process, ensure that the lower die base 4 is stably supported on the die pad 3, ensure the safe operation of the equipment, extend the service life of the structural components, and improve production reliability.

[0030] It is understandable that when the lower die holder 4 is normally matched and set on the upper end of the die pad 3, the height difference between the upper surface of the traveling side beam 6 and the lower surface of the lower die holder 4 directly above it is 5mm; when the lifting cylinder 11 reaches its maximum stroke, it lifts the lower die holder 4 to its maximum height through the lifting support 12. At this time, the height difference between the upper surface of the traveling side beam 6 and the lower surface of the lower die holder 4 directly above it is 25mm, and this height difference allows the rear-mounted shim assembly 11 to follow the traveling side beam 6 and pass under the lower die holder 4, thereby allowing the quick die changing device to run along the guide rail 5 to a specific position, and to be transported by overhead crane to other forging machines for die changing operations, further improving the efficiency of the quick die changing device and effectively reducing costs.

[0031] In a feasible embodiment, the quick mold changing device further includes a driven wheel adjustment device 10, with two driven wheel adjustment devices 10 respectively connected to both ends of the driven shaft of one driven wheel 9; the driven wheel adjustment device 10 includes: a baffle 1001, an adjusting bolt 1002, a bearing mounting plate 1003, a bearing 1004, and a pressure cap 1005; the baffle 1001 is detachably disposed on one side of the traveling side beam 6; the bearing mounting plate 1003 has several vertical oblong holes on its edge, and is adjustablely disposed on one side of the traveling side beam 6 by connecting bolts passing through the oblong holes, and is located directly below the baffle 1001; the shaft Bearing 1004 is embedded in the through hole in the middle of the bearing mounting plate 1003; bearing 1004 is close to the traveling side beam 6 and connected to the driven shaft of the driven wheel 9; adjusting bolt 1002 passes through the baffle 1001 and its bottom end abuts against the upper surface of the bearing mounting plate 1003; pressure cap 1005 is bolted to the side of the bearing mounting plate 1003 away from the traveling side beam 6; pressure cap 1005 has an annular protrusion on the side facing the bearing mounting plate 1003, the outer diameter of the annular protrusion is smaller than the inner diameter of the through hole in the middle of the bearing mounting plate 1003, and abuts against the side of the bearing 1004. During use, by adjusting the relative positions of the pressure caps 1005 on both sides of the same driven wheel 9 on the bearing mounting plate 1003, the lateral position of the driven wheel 9 within the traveling side beam 6 can be precisely adjusted to ensure its alignment with the guide rail 5. Simultaneously, the vertical oblong holes on the bearing mounting plate 1003, when fitted with connecting bolts, allow for fine-tuning of the mounting height of the bearing mounting plate 1003 in the vertical direction, thereby adjusting the vertical position of the driven wheel 9 to accommodate the actual installation reference deviation of the guide rail 5. Furthermore, during adjustment, the adjusting bolt 1002 passes through the baffle 1001 and abuts against the upper surface of the bearing mounting plate 1003, achieving pre-tightening and height limiting. The pressure cap 1005 abuts against the bearing 1004 via an annular protrusion, ensuring reliable axial fixation of the bearing. It is understood that through the above design, this structure facilitates on-site assembly and subsequent maintenance, effectively ensuring good contact between the driven wheel 9 and the guide rail 5, reducing running resistance and wear, improving walking stability and guiding accuracy, thereby enhancing the adaptability and reliability of the entire quick mold change device.

[0032] In an optional embodiment, the driven wheel adjustment device 10 further includes a retaining ring 1006, which is sleeved on the outside of the driven shaft of the driven wheel 9 and close to the bearing 1004. The retaining ring 1006 is used to axially limit the bearing 1004 to prevent it from axially moving during operation, thereby ensuring the stability and reliability of the driven wheel 9 installation and effectively improving the transmission accuracy and the overall smoothness of the device operation.

[0033] In an optional embodiment, the elevation assembly 14 includes: a push-pull cylinder 1401 disposed on the upper end of the traveling side beam 6 or the mounting frame 601, and a pad 1402 fixedly connected to the movable end of the push-pull cylinder 1401. During use, the push-pull cylinder 1401 drives the pad 1402 to extend between the lower mold base 4 and the mold pad 3, achieving stable lifting and support of the lower mold base 4, ensuring its safe transfer after disengaging from the positioning key. The operation is reliable, the positioning is accurate, and the automation level and operational safety of the mold changing process are effectively improved.

[0034] In an optional embodiment, the quick mold changing device further includes several lifting guide columns 13, which are detachably connected to the lower mold base 4. The bottom end of the lifting guide column 13 passes through the lower mold base 4 and extends into the corresponding through hole provided at the upper end of the traveling side beam 6, so as to provide precise guidance during the lifting process of the lifting cylinder 11, effectively prevent the lower mold base 4 from shifting or tilting, ensure smooth lifting action and accurate positioning, and improve the safety and repeatability of mold changing.

[0035] In an optional embodiment, the pad 1402 is provided with a U-shaped groove on the side facing the lifting guide column 13. This groove works in conjunction with the lifting guide column 13 during the mold changing process to effectively transmit the supporting force, prevent the lower mold base 4 from shifting or tilting, and ensure its stability and safety during the transfer process.

[0036] In an optional embodiment, the quick mold change device further includes a limiting baffle 15 and a proximity switch 16. The limiting baffle 15 is fixedly disposed on the outside of the mounting frame 601 and corresponds to the proximity switch 16 disposed on one side of the machine base 2. The proximity switch 16 is communicatively connected to the drive component 7 and is used to send a stop signal to the drive component 7 when the limiting baffle 15 reaches a predetermined position. It is understood that through the above design, when the traveling side beam 6 moves and drives the limiting baffle 15 to trigger the proximity switch 16, the proximity switch 16 sends a stop signal to the drive component 7. After receiving the stop signal, the drive component 7 stops operating, achieving precise positioning and automatic stopping of the traveling side beam 6 at a predetermined position, effectively preventing overstepping collisions and ensuring equipment and personnel safety.

[0037] In an alternative embodiment, the proximity switch 16 is an inductive, capacitive, or Hall effect proximity switch.

[0038] The working principle of this utility model is as follows: During the mold changing and removal process, multiple lifting cylinders 11 are activated to simultaneously lift the lifting support 12, raising the lower mold base 4 and above as a whole, so that it is separated from the positioning key on the mold pad 3; after it is in position, the push-pull cylinder 1401 is activated to push the pad block 1402 to be inserted horizontally into the gap between the lower mold base 4 and the traveling side beam 6; then the height of the moving end of the lifting cylinder 11 decreases, so that the lower mold base 4 falls smoothly and is supported on the pad block 1402, completing the support conversion. At this time, the piston rod of the lifting cylinder 11 is completely retracted; then the drive component 7 is activated, and the drive motor drives the drive wheel 8 to run on the guide rail 5 through the reducer, so that the traveling side beam 6 together with the lower mold base 4 installed on it moves outward along the guide rail, realizing the automatic removal of the mold. During mold changing and movement, the process is reversed: the drive unit 7 is activated, moving the mold changing device and lower mold base 4 back to the inside of the machine body to the predetermined position until the limit baffle 15 triggers the proximity switch 16. The drive unit 7 receives the signal and stops, ensuring accurate positioning. Then, the lower mold base 4 is lifted by the lifting cylinder 11, causing it to detach from the pad 1402. The pad 1402 is then pulled out of the gap by the push-pull cylinder 1401. Afterward, the movable end of the lifting cylinder 11 descends, driving the lower mold base 4 to slowly descend and accurately reposition itself on the mold pad 3, completing the installation. The entire process ensures the guiding accuracy of vertical movement through the lifting guide column 13 and the smoothness of movement through the driven wheel adjustment device 10, achieving safe, efficient, and accurate rapid mold changing operation.
