Description

Technical Field

[0001] This invention relates to the field of forging technology, and in particular to a forging apparatus and forging method for fire-fighting equipment. Background Technology

[0002] Firefighting equipment is a core component of emergency rescue, and its structural strength, corrosion resistance, and other properties directly affect rescue safety. With the increasing complexity of scenarios, the performance requirements for equipment are continuously rising, making forging a core processing method.

[0003] For example, in the patent CN120133435B, "A Forging Device for Firefighting Equipment," when forging a fire valve stem blank, the pressure rod contacts the pressure plate to compress the first spring, causing the first trapezoidal block to slide down and the second trapezoidal block to move inward. Utilizing the inclined structure on the outer side of the die base plate, the die base plate is moved upward, shortening the distance between the valve stem blank and the main punch, thus achieving punch clearance compensation. However, the core characteristic of the punch's descent phase is the large instantaneous impact force. At the moment the punch contacts the blank, the impact force is transmitted in reverse through the blank to the die base plate. At this time, the die base plate is in the process of rising, and the impact force causes the die base plate to "bounce" or "instantly sink," making it impossible to accurately stop at the target compensation height, ultimately leading to a deviation in the clearance compensation between the blank and the punch. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a forging device and forging method for fire-fighting equipment.

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

The second gear meshes with a rack, and the one-way bearing is disposed between the rotating shaft and the second gear.

[0016] A forging method for a fire-fighting equipment forging device as described in any one of claims 1-9, comprising the following steps:

[0017] S1. The hydraulic cylinder is started, the forging head descends, and the blank in the blank positioning groove is forged;

[0018] S2. When the forging head breaks or bends due to prolonged operation, it compresses the extrusion block.

[0019] S3. The rotating disk rotates, driving the first gear and screw to rotate;

[0020] S4. The nut and load-bearing block rise and stop at the target compensation height to compensate for the gap deviation between the blank and the forging head;

[0021] S5. After the load-bearing block rises to the target height, the first slider and the second slider clamp together to form a rigid support structure to support the load-bearing block.

[0022] S6. The missing gear rotates until it gradually loses engagement with the rack;

[0023] S7. The rack drives the second gear to rotate, and the warning plate rotates to the warning surface.

[0024] The present invention has the following beneficial effects:

[0025] 1. In this invention, when the forging head is used for a long time and develops chipping, bending, protrusions, etc., the damaged part of the forging head squeezes the extrusion block, the rotating disk rotates, driving the first gear and screw to rotate, and the nut and load-bearing block rise and stay at the target compensation height to compensate for the gap deviation between the blank and the forging head.

[0026] 2. Furthermore, when the load-bearing block rises to the target height, the first slider rises synchronously and squeezes the second slider. When the first slider is released from the state of squeezing the second slider, the second slider resets under the action of the second spring and clamps with the first slider to form a rigid support structure to support the load-bearing block.

[0027] 3. Furthermore, when the screw rotates, since a one-way bearing is provided between the second gear and the rotating shaft, the rotating shaft does not rotate. When the push block travels to the maximum distance in the first slide groove, the missing gear rotates until it gradually loses engagement with the rack. The rack is reset under the action of the third spring, driving the second gear to rotate. The warning plate rotates to the warning surface to warn and remind the operator to maintain the device in a timely manner. Attached Figure Description

Detailed Implementation

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Example 1:

[0044] Reference Figures 1-8 and Figure 11 A fire-fighting equipment forging device includes a machine tool 1, a frame 2, a mounting box 3, a hydraulic cylinder 4, a forging head 5, a blank positioning groove 6, and a load-bearing block 7. The machine tool 1 is equipped with a detection component for detecting the surface working condition of the forging head 5. The machine tool 1 is also equipped with a support component for supporting the load-bearing block 7. The machine tool 1 is also equipped with a warning component for warning and reminding the operator.

[0045] The detection assembly includes an annular detection sleeve 8, a push block 13, a rotating disk 14, a first slide groove 15, an annular track 16, and a triggering mechanism. The triggering mechanism is used to drive the push block 13 to slide. The annular detection sleeve 8 is located below the hydraulic cylinder 4. The rotating disk 14 is located on the outer periphery of the annular detection sleeve 8 and rotates on the annular track 16. The first slide groove 15 is located on the rotating disk 14, and the push block 13 slides in the first slide groove 15.

[0046] The triggering mechanism includes a squeezing block 9, a first slider box 10, a squeezing rod 11, and a first spring 12. The first slider box 10 is fixedly connected through the annular detection sleeve 8. The squeezing block 9 is fixedly connected to one end of the squeezing rod 11, and the other end of the squeezing rod 11 is fixedly connected to the push block 13. The squeezing block 9 and the squeezing rod 11 slide inside the first slider box 10. One end of the first spring 12 is fixedly connected to the squeezing block 9, and the other end is fixedly connected to the bottom of the first slider box 10.

[0047] There are 6 first slide grooves 15 and push blocks 13. The first slide grooves 15 are distributed in a ring-shaped inclined manner on the rotating disk 14, and there are 6 sets of triggering mechanisms.

[0048] The support assembly includes a first gear 17, a screw 18, a nut 19, a limiting slider 20, a second slide groove 21, and an interlocking mechanism, which provides rigid support for the load-bearing block 7.

[0049] The outer circumference of the rotating disk 14 is provided with gear teeth, which mesh with the first gear 17. One end of the screw 18 is rotatably connected to the lower end of the frame 2, and the other end is rotatably connected to the surface of the machine tool 1. The first gear 17 is fixedly connected to the end of the screw 18 near the frame 2. The nut 19 is threadedly connected to the screw 18 and fixedly connected to the load-bearing block 7. Three limit sliders 20 are provided and fixedly connected to the side wall of the load-bearing block 7. Three second slide grooves 21 are provided on the machine tool 1, and the limit sliders 20 slide in the corresponding second slide grooves.

[0050] In this embodiment, if the forging head 5 experiences wear or damage such as chipping, bending, or localized protrusions after long-term, high-frequency forging operations, it will cause a deviation in the fit clearance between it and the blank, affecting the forging accuracy. At this time, the automatic clearance compensation function of the device will be triggered. The damaged part of the forging head 5 will form a pressing action with the preset extrusion block 9 during the forging process. This extrusion force will drive the push block 13 to slide in the first slide groove 15, and the rotating disk 14 will rotate synchronously. After the rotating disk 14 rotates, it drives the first gear 17 to rotate through the gear transmission mechanism, which in turn drives the coaxially connected screw 18 to rotate at a uniform speed. As the screw 18 rotates, the nut 19 with its threaded engagement will rise smoothly along the screw axis, and at the same time drive the load-bearing block 7 on the nut 19 to rise synchronously until the load-bearing block 7 stops at the preset target compensation height.

[0051] It should be noted that this compensation process can offset the gap deviation caused by damage to the forging head 5 in real time, ensuring that a reasonable forging gap is always maintained between the billet and the forging head 5. This effectively avoids problems such as billet forging size deviation and forming defects caused by abnormal gap, ensuring the stability of forging operations and product qualification rate, extending the service life of the damaged forging head 5, and reducing the cost and downtime losses of frequent parts replacement.

[0052] Example 2;

[0053] Reference Figures 7-10 and Figure 12 , Figure 13 The interlocking mechanism includes a first slider 22, a second slider 23, a second slider box 24, a slide rod 25, a second spring 26, and a pull plate 27. The first slider 22 is disposed on the side wall of the load-bearing block 7. The second slider 23 is inclined and cooperates with the first slider 22. One end of the slide rod 25 is fixedly connected to the second slider 23, and the other end is fixedly connected to the pull plate 27. The second slider 23 and the slide rod 25 slide within the second slider box 24. One end of the second spring 26 is fixedly connected to the second slider 23, and the other end is fixedly connected to the bottom of the second slider box 24.

[0054] Two sets of interlocking mechanisms are provided. The second slider box 24 is installed on the side wall of the machine tool 1, and the slide rod 25 passes through the bottom of the second slider box 24 and the side wall of the machine tool 1.

[0055] In this embodiment, when the load-bearing block 7 rises to the preset target compensation height under the drive of the screw 18, the first slider 22, which is synchronously linked with the load-bearing block 7, will also rise. During the rising process, the first slider 22 will compress the preset second slider 23, forcing the second slider 23 to overcome the elastic force of the second spring 26 and slide to the side, making room for the first slider 22 to continue rising. After the load-bearing block 7 reaches the target height, the first slider 22 stops rising and releases the compression state on the second slider 23. At this time, the compressed second spring 26 quickly releases its elastic potential energy, driving the second slider 23 to quickly reset. The reset second slider and the first slider 22 form a tightly engaged locking structure, together constituting a stable rigid support system.

[0056] This rigid support structure can effectively resist the impact and vibration generated during forging operations, prevent the load-bearing block 7 from shifting or settling under stress, ensure the stability of the compensation height, and thus ensure the gap between the billet and the forging head 5, providing a solid guarantee for the accuracy and reliability of subsequent forging operations.

[0057] Example 3:

[0058] Reference Figure 1 , Figure 2 , Figure 7 , Figure 9 The warning assembly includes a missing gear 28, a rack 30, a guide rod 31, a third spring 32, a warning plate 35, and a rotating structure. The rotating mechanism is used to drive the warning plate 35 to rotate. A slot is provided on the machine tool 1. The missing gear 28 is rotatably connected to the lower end of the screw 18. The missing gear 28 meshes with the rack 30. The rack 30 slides on the guide rod 31. The two ends of the guide rod 31 are fixedly connected to the two sides of the slot. One end of the third spring 32 is fixedly connected to the side wall of the slot, and the other end is fixedly connected to the end of the rack 30 near the missing gear 28. The warning plate 35 is set on the machine tool 1.

[0059] The rotating mechanism includes a second gear 29, a one-way bearing 33, and a rotating shaft 34. One end of the rotating shaft 34 is fixedly connected to the second gear 29, and the other end is fixedly connected to the lower end of the warning plate 35. The second gear 29 meshes with the rack 30, and the one-way bearing 33 is disposed between the rotating shaft 34 and the second gear 29.

[0060] In this embodiment, during the process of the screw 18 being driven to rotate to achieve backlash compensation, since a one-way bearing 33 is assembled between the second gear 29 and the rotating shaft 34, the one-way bearing 33 will restrict the rotating shaft 34 from rotating synchronously with the second gear 29, so that the rotating shaft 34 always remains stationary.

[0061] When the load-bearing block 7 rises to the target compensation height and the push block 13 slides along the first slide groove 15 to the maximum travel distance, the transmission system synchronously drives the missing gear 28 to rotate. At this time, the missing gear 28 gradually rotates to the missing tooth area and completely disengages from the meshing relationship with the rack 30. After losing the meshing constraint, the rack 30 quickly rebounds and resets under the elastic restoring force of the third spring 32, and then drives the second gear 29 and the rotating shaft 34 to rotate through the rack 30 transmission.

[0062] The rotation of the rotating shaft 34 causes the connected warning plate 35 to rotate synchronously, so that the warning surface of the warning plate, such as the side with conspicuous markings, warning colors, or prompt text, quickly faces the operator's visible area, forming a clear and intuitive warning reminder. This design can promptly inform the operator that the forging head 5 has shown significant wear, the device has completed clearance compensation, and the damaged forging head 5 needs to be inspected, maintained, or replaced as soon as possible. This avoids compensation failure due to continuous wear of the forging head 5, affecting forging accuracy, or causing equipment failure or safety hazards, thus ensuring the continuity and safety of forging operations.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
