Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment processing, in particular to a fire-fighting equipment forging device. Background Art

[0002] The fire hydrant valve stem is a key component in fire hydrant valves. As a firefighting device, it is used for transmission, connected to the actuator above, and drives the valve core below to move or rotate, thereby opening or closing the fire hydrant valve and controlling the flow of fire water. During firefighting, the fire hydrant can be quickly opened and closed by operating the valve stem, which has a significant impact on the efficiency and effectiveness of firefighting. In order to refine the internal grain of the valve stem metal, dense the structure, eliminate internal defects, and significantly improve the strength, toughness, hardness and other mechanical properties of the valve stem, it is forged.

[0003] During the forging process of fire hydrant valve stems, the die and the stem blank frequently come into contact and rub against each other. Over time, the die surface gradually wears, causing key die dimensions to change. This wear increases the previously precise clearance, preventing the stem blank from forming within the ideal space during forging. This leads to problems such as outer diameter deviation and increased surface roughness, compromising the valve stem's forming accuracy and product quality. Summary of the Invention

[0004] In order to solve the technical problems raised in the above-mentioned background technology, the present invention provides a fire-fighting equipment forging device, which has the advantages that: through the setting of the compensation component, the gap of the mold that becomes larger due to wear is compensated, the effect of precise matching of the mold is maintained, and the valve stem blank is ensured to be formed in the ideal space, effectively avoiding the problems such as valve stem outer diameter dimension deviation caused by mold wear, improving the molding accuracy and product quality of the valve stem, and at the same time extending the service life of the mold, reducing the production cost caused by frequent replacement of mold wear.

[0005] In order to achieve the above object, the present invention specifically adopts the following technical solutions:

[0006] A firefighting equipment forging device includes a base, the top of the base is connected to a top plate via a plurality of support rods, a connecting plate is provided between the top plate and the base, the connecting plate is fixedly connected to the plurality of support rods, a connecting block is slidably connected to the interior of the connecting plate, a cylinder is provided on the top of the top plate, the output end of the cylinder is connected to the connecting block, and compensation components are provided on both sides of the connecting block;

[0007] The compensation assembly includes a driving component, which includes a driving rod. The number of the driving rods is set to two, and the two driving rods are fixedly connected to both sides of the connecting block respectively. The bottom ends of the two driving rods are fixedly connected to an oblique rod, and one end of the two oblique rods is fixedly connected to a pressure rod.

The outer walls of the two long rods are each sleeved with a first spring. The top ends of the two long rods are fixedly connected with a pressure plate, and the two pressure plates are respectively located above the corresponding pressure rods.

[0009] Through the above technical solution: through the setting of the compensation component, when the pressure of the main punch exceeds the limit, the pressure rod contacts the pressure plate to compress the first spring, driving the first trapezoidal block to slide down, causing the second trapezoidal block to move inward, and utilizing the inclined structure of the outer side of the die base plate to drive the die base plate to move upward, shortening the distance between the valve stem blank and the main punch, compensating for the gap between the die that has increased due to wear, maintaining the effect of precise matching gap of the die, ensuring that the valve stem blank is formed in the ideal space, effectively avoiding problems such as valve stem outer diameter deviation due to die wear, improving the forming accuracy of the valve stem and product quality, while extending the service life of the die, and reducing the production cost caused by frequent replacement of die wear.

[0010] The present invention is further configured such that the bottoms of the two long rods are fixedly connected to a first trapezoidal block, and the two ends of the two first springs are fixedly connected to the pressure plate and the base respectively.

[0011] The present invention is further configured such that a second trapezoidal block is provided on each side of the two first trapezoidal blocks facing each other, two grooves are provided inside the base, and the two first trapezoidal blocks and the second trapezoidal block are slidably connected to the corresponding grooves respectively.

[0012] The present invention is further configured such that a driving motor is provided inside the base, the output end of the driving motor is connected to a cross block via a rotating shaft, the inside of the base is rotatably connected to a die base plate, and the outer side of the die base plate is inclined.

[0013] The present invention is further configured such that a cylinder is fixedly connected to the bottom of the mold base plate, a cross groove is provided inside the cylinder, and the cross groove matches the cross block.

[0014] Through the above technical solution: the cylindrical internal cross groove of the mold base plate is matched with the cross block at the top of the drive motor, which enables the free lifting of the mold base plate and ensures the smooth progress of the gap compensation action. At the same time, after the mold base plate is lifted for gap compensation, the power transmission can still be maintained.

[0015] The present invention is further configured such that a plurality of placement rings are provided above the die base plate, a main punch is fixedly connected to the bottom of the connecting block, and side punching components are provided on both sides of the base.

[0016] Through the above technical solution: the placing ring is used to place the blank.

[0017] The present invention is further configured such that the lateral stamping assembly includes a connecting rod, the number of the connecting rods is set to two, the two connecting rods are respectively rotatably connected to the corresponding driving rods, and the bottom ends of the two connecting rods are rotatably connected to a round rod.

[0018] The present invention is further configured such that two U-shaped rails are fixedly connected on both sides of the base, a ball group is provided inside each U-shaped rail, the outer wall of each ball group is in contact with the inner wall of the corresponding U-shaped rail, sliders are provided at both ends of each ball group, each two sliders located above are connected to the corresponding round rods, a sliding groove is provided on the opposite side of each two U-shaped rails, and the two ends of the two round rods are slidably connected to the corresponding sliding grooves.

[0020] The present invention is further configured such that a second spring is sleeved on the outer end of each rod body, and both ends of each second spring are fixedly connected to the corresponding U-shaped track and the plate body respectively.

[0021] Through the above technical solution: when the cylinder drives the main punch to punch vertically, the vertical movement is converted into lateral displacement by utilizing the linkage of the driving rod, connecting rod, round rod, slider, ball group and U-shaped track, and the second spring is stretched to make the side punch forge the side of the blank. After the main punch is reset, the spring rebounds and drives the slider to reset, thereby achieving the effect of synchronously completing vertical and lateral forging in a single stamping stroke, realizing multi-directional processing and improving forging efficiency. At the same time, the elastic reset of the spring ensures the stable operation and cyclic operation capability of the mechanism, effectively solving the problem that traditional equipment requires multiple positioning processing, and improving the production quality and efficiency of fire valve stems.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention sets a compensation component. When the pressure of the main punch exceeds the limit, the pressure rod contacts the pressure plate to compress the first spring, driving the first trapezoidal block to slide down and the second trapezoidal block to move inward. The outer inclined structure of the die base plate is utilized to drive the die base plate to move upward, shortening the distance between the valve stem blank and the main punch, compensating for the gap of the die that becomes larger due to wear, maintaining the effect of precise matching gap of the die, ensuring that the valve stem blank is formed in an ideal space, effectively avoiding problems such as valve stem outer diameter deviation due to die wear, improving the forming accuracy of the valve stem and product quality, and at the same time extending the service life of the die and reducing the production cost caused by frequent replacement of die wear.

[0024] 2. The present invention realizes the free lifting of the mold base plate by matching the cross groove inside the cylinder of the mold base plate with the cross block at the top of the driving motor, ensuring the smooth execution of the gap compensation action. At the same time, after the mold base plate is lifted to perform the gap compensation, the power transmission can still be maintained.

[0025] 3. The present invention achieves the effect of synchronously completing vertical and lateral forging in a single stamping stroke through the setting of the lateral stamping assembly, realizes multi-directional processing, and improves forging efficiency. At the same time, the elastic reset of the spring ensures the stable operation and cyclic operation capability of the mechanism, thereby improving the processing efficiency of the fire valve stem.

[0036] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] Reference Figures 1-9 A fire-fighting equipment forging device includes a base 1, the top of the base 1 is connected to a top plate 3 through a plurality of support rods, a connecting plate 2 is provided between the top plate 3 and the base 1, the connecting plate 2 is fixedly connected to the plurality of support rods, a connecting block 8 is slidably connected to the inside of the connecting plate 2, a cylinder 4 is provided on the top of the top plate 3, the output end of the cylinder 4 is connected to the connecting block 8, and compensation components are provided on both sides of the connecting block 8;

[0039] The compensation assembly includes a driving component, which includes a driving rod 11. The number of the driving rods 11 is set to two. The two driving rods 11 are fixedly connected to the two sides of the connecting block 8 respectively. The bottom ends of the two driving rods 11 are fixedly connected to an inclined rod 12, and one end of the two inclined rods 12 is fixedly connected to a pressure rod 13.

[0040] The compensation assembly also includes a compensation component, which includes a long rod 14. The number of long rods 14 is set to two. The outer walls of the two long rods 14 are each sleeved with a first spring 15. The top ends of the two long rods 14 are fixedly connected with a pressure plate 18. The two pressure plates 18 are respectively located above the corresponding pressure rods 13.

[0041] Reference Figure 3-Figure 9 The bottoms of the two long rods 14 are fixedly connected with a first trapezoidal block 16, and the two ends of the two first springs 15 are fixedly connected to the pressure plate 18 and the base 1 respectively. The two first trapezoidal blocks 16 are provided with a second trapezoidal block 17 on the opposite side. Two grooves are provided inside the base 1, and the two first trapezoidal blocks 16 and the second trapezoidal blocks 17 are slidingly connected to the corresponding grooves respectively. A drive motor 9 is provided inside the base 1, and the output end of the drive motor 9 is connected to a cross block 20 through a rotating shaft. The inside of the base 1 is rotatably connected to the mold base disk 5, and the outer side of the mold base disk 5 is inclined. The bottom of the mold base disk 5 is fixedly connected to the cylinder 10, and a cross slot 19 is provided inside the cylinder 10, and the cross slot 19 matches the cross block 20.

[0042] During stamping, first place the fire valve stem blank inside the placing ring 6. The placing ring 6 has a limiting effect on the blank. Then start the driving motor 9. Its output end drives the cross block 20 to rotate, cooperates with the cross groove 19 in the cylinder 10, drives the die base plate 5 to rotate, and uses the die base plate 5 to complete the station switching, and transfers the valve stem blank in the placing ring 6 to the processing position. Then the cylinder 4 is started to push the connecting block 8 down along the connecting plate 2. The connecting block 8 drives the main punch 7 to punch vertically downward, and the driving rods 11 on both sides drop accordingly. During the normal forging process, the main punch 7 is in a state of normal forging because the distance the main punch 7 punches the blank is slightly greater than the distance between the pressure rod 13 and the pressure plate 18. , the pressure rod 13 will not contact the pressure plate 18. When the pressure of the main punch 7 exceeds the limit (when wear or damage occurs), the main punch 7 will be in a lower position to complete the stamping of the blank. At this time, the pressure rod 13 will contact the pressure plate 18. When the pressure rod 13 contacts the pressure plate 18, it compresses the first spring 15. At this time, the long rod 14 will drive the first trapezoidal block 16 to slide downward inside the groove of the base 1. When the first trapezoidal block 16 slides downward, it drives the second trapezoidal block 17 to move inward. Because the outer side of the die base plate 5 is inclined, when the second trapezoidal block 17 moves inward, it will drive the die base plate 5 to move upward, and the distance between the valve stem blank in the placement ring 6 and the main punch 7 is shortened, forming a compensation mechanism.

[0043] Because the mold base plate 5 is connected to the cross block 20 at the top of the drive motor 9 through the cross slot 19 inside the cylinder 10, when the mold base plate 5 is lifted to compensate for the gap, the cross block 20 will always be located inside the cross slot 19, which does not affect the transmission of power and allows the mold base plate 5 to be lifted to compensate for the gap.

[0044] The present invention sets a compensation component. When the pressure of the main punch 7 exceeds the limit, the pressure rod 13 contacts the pressure plate 18 to compress the first spring 15, driving the first trapezoidal block 16 to slide down, and the second trapezoidal block 17 to move inward. The outer inclined structure of the die base plate 5 is utilized to drive the die base plate 5 to move upward, shortening the distance between the valve stem blank and the main punch 7, compensating for the gap of the die that becomes larger due to wear, achieving the effect of maintaining the precise fitting gap of the die, ensuring that the valve stem blank is formed in an ideal space, effectively avoiding problems such as valve stem outer diameter size deviation due to die wear, improving the valve stem forming accuracy and product quality, and at the same time extending the service life of the die, reducing the production cost caused by frequent replacement of die wear.

[0045] Reference Figure 1-Figure 3 A plurality of placement rings 6 are provided above the die base plate 5, a main punch 7 is fixedly connected to the bottom of the connecting block 8, and lateral stamping components are provided on both sides of the base 1.

[0046] Reference Figure 6-Figure 8The lateral stamping assembly includes a connecting rod 23, the number of which is set to two, and the two connecting rods 23 are respectively rotatably connected to the corresponding driving rod 11. The bottom ends of the two connecting rods 23 are rotatably connected to the round rod 24. Two U-shaped rails 21 are fixedly connected on both sides of the base 1. A ball group 26 is provided inside each U-shaped rail 21. The outer wall of each ball group 26 contacts the inner wall of the corresponding U-shaped rail 21. Sliders 25 are provided at both ends of each ball group 26. Every two slides 25 located above are connected to the corresponding round rod 24. Every two A slide groove 22 is provided on the opposite side of each U-shaped track 21, and the two ends of the two round rods 24 are respectively slidably connected to the corresponding slide groove 22. One end of each slider 25 located below is fixedly connected to a rod body 28. Every two rod bodies 28 extend through and extend to the outside of the corresponding U-shaped track 21 and are fixedly connected to a plate body 30. The facing ends of the two plates 30 are fixedly connected to the side punch 27. The outer end of each rod body 28 is sleeved with a second spring 29, and the two ends of each second spring 29 are respectively fixedly connected to the corresponding U-shaped track 21 and the plate body 30.

[0047] When the cylinder 4 is activated to push the connecting block 8 down along the connecting plate 2, driving the main punch 7 to punch vertically downward, the driving rods 11 on both sides of the connecting block 8 also descend. During the descent of the driving rod 11, the connecting rod 23 is rotated to drive the sliders 25 on both sides of the round rod 24 to move outward along the U-shaped track 21. When the two upper sliders 25 move outward, they can drive the ball group 26 (composed of multiple balls) to roll along the U-shaped track 21. Because the outer wall of the ball group 26 is in close contact with the inner wall of the U-shaped track 21, it can push the two lower sliders 25 inward, thereby driving the rod body 28 inward. At this time, the second spring 29 is stretched, and the two side punches 27 can just forge the side of the blank.

[0048] When the main punch 7 is reset, the second spring 29 rebounds, driving the slider 25 to reset, so as to facilitate the next forging.

[0049] The first spring 15 and the second spring 29 are both high-strength alloy springs with strong elasticity and high load bearing capacity.

[0050] The side punch 27 can forge and punch two parts at a time. When the part needs to be replaced, the machine is first stopped, and then the blank is clamped by manual pliers and rotated, and then placed inside the placement ring 6 to continue forging.

[0051] Through the setting of the lateral stamping assembly, when the cylinder 4 drives the main punch 7 to stamp vertically, the vertical movement is converted into lateral displacement by utilizing the linkage of the driving rod 11, the connecting rod 23, the round rod 24, the slider 25, the ball group 26 and the U-shaped track 21, and the second spring 29 is stretched to cause the side punch 27 to forge the side of the blank. After the main punch 7 is reset, the second spring 29 rebounds and drives the slider 25 to reset, achieving the effect of synchronously completing vertical and lateral forging in a single stamping stroke, realizing multi-directional processing and improving forging efficiency. At the same time, the elastic reset of the second spring 29 ensures the stable operation and cyclic operation capability of the mechanism, effectively solving the problem that traditional equipment requires multiple positioning processing, and improving the production quality and efficiency of fire valve stems.

[0052] Working principle: In the forging operation of the fire valve stem, the fire valve stem blank to be processed is first placed in the placement ring 6. The placement ring 6 can play a role of limiting, which can ensure that the blank remains stable during the subsequent processing. Then, the drive motor 9 is started, and the output end of the drive motor 9 drives the cross block 20 to rotate. The precise fit between the cross block 20 and the cross groove 19 inside the cylinder 10 is used to stably transmit the rotational power to the die base plate 5, and the die base plate 5 is driven to rotate according to the set program, thereby completing the work station switching action and turning the placement ring 6 loaded with the valve stem blank to the processing position.

[0053] Once the valve stem blank is in place, the cylinder 4 begins operating, its output end pushing the connecting block 8 downward along the connecting plate 2. As the connecting block 8 descends, it drives the main punch 7, affixed to its base, to press vertically downward, initially forging the valve stem blank. Simultaneously, the drive rods 11 on either side of the connecting block 8 also descend. As the drive rods 11 descend, they rotate the connecting rod 23, driving the round rod 24. This movement, in turn, drives the upper slider 25 connected to it, causing the ball assembly 26 to roll within the U-shaped track 21. Because the outer wall of the ball assembly 26 is in close contact with the inner wall of the U-shaped track 21, the upper slider 25 drives the lower slider 25 inward, pulling the rod body 28 inward and stretching the second spring 29. Ultimately, the side punches 27 simultaneously forge the side surfaces of the blank, achieving multi-directional vertical and lateral machining. When the main punch 7 completes the punching task and resets, the second spring 29 rebounds by its own elasticity, driving the slider 25 to reset, and prepare for the next forging cycle.

[0054] In a normal forging process, the distance that the main punch 7 punches the blank is slightly greater than the distance between the pressure rod 13 and the pressure plate 18, so the pressure rod 13 will not contact the pressure plate 18. However, when the main punch 7 is worn, deformed or damaged due to long-term use, resulting in excessive pressure, the main punch 7 needs to be in a lower position to complete the punching of the blank. At this time, the pressure rod 13 will contact the pressure plate 18 and compress the first spring 15. Under the action of the first spring 15, the long rod 14 drives the first trapezoidal block 16 to slide downward in the groove body of the base 1. During the downward movement of the first trapezoidal block 16, the second trapezoidal block 17 is driven inward by the inclined structure. Because the outer side of the die base plate 5 is tilted, the movement of the second trapezoidal block 17 will prompt the die base plate 5 to move upward, thereby shortening the distance between the valve stem blank and the main punch 7 and achieving gap compensation.

[0055] Due to the design of the cross block 20 and the cross slot 19, even when the die base plate 5 is lifted to compensate for the gap, it will not affect the normal transmission of power, thereby ensuring the operation of the equipment.

[0056] When the forging part of the side punch 27 needs to be replaced, the operator first shuts down the equipment to ensure that it is in a safe state, then uses special pliers to clamp the valve stem blank and rotate it. After adjusting it to the required processing position, it is placed back into the placement ring 6, and then the equipment is started to continue the forging operation.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
