Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a stamping forming device for fire extinguisher bracket parts. Background Technology

[0002] In existing stamping forming devices for fire extinguisher bracket parts, the die and stamping head are typically fixed or fastened with multiple bolts. Changing dies to different specifications requires disassembling multiple connecting parts, which is cumbersome and time-consuming, increasing production preparation time and making it difficult to meet the rapid changeover requirements for small batches and diverse parts. Furthermore, traditional devices lack dedicated positioning and guiding structures, making it easy for the die and stamping head to deviate in installation position. During stamping, misalignment of the die can generate lateral forces, resulting in low part forming accuracy, surface burrs or deformation, and even accelerated die wear, affecting equipment lifespan and product yield. In addition, workpiece positioning during stamping relies heavily on manual assistance, further increasing operational errors and labor costs. Therefore, there is an urgent need for a stamping forming device that enables rapid die and stamping head replacement and has precise positioning capabilities to solve the problems of inconvenient replacement and insufficient positioning accuracy in existing technologies.

[0003] Chinese Patent No. CN222001523U discloses a stamping die for producing fire extinguisher brackets, relating to the field of die stamping. The die includes a support base with a top plate fixed to its top. A hydraulic cylinder is fixed to the top of the top plate. A stamping module is located on one side of the support base. The hydraulic cylinder has a telescopic end at its bottom, extending beyond the top plate and connected to a connecting base plate. A stamping block is fixed to the bottom of the connecting base plate. The stamping module and the stamping block are vertically aligned. In practical operation, when the telescopic end of the hydraulic cylinder presses downwards, a vacuum pump is activated. The vacuum pump draws material from the groove through an air hole, which helps to fix the material inside. Simultaneously, the air hole collects debris and dust generated during the internal pressing process. However, this device cannot replace the die, limiting its application to stamping only specific components. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned prior art by changing the die and the stamping head to achieve stamping of different dies, thereby improving the production efficiency of fire extinguisher bracket parts.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A stamping forming apparatus for fire extinguisher bracket parts is used to stamp out the required parts for fire extinguisher wall brackets by changing the die. The apparatus includes: a base plate, a stamping cylinder, guide columns, a die, and a stamping head; at least four guide columns are installed on the base plate, and the die is detachably installed on the base plate.

[0007] The top of the guide post is fixed with a mounting plate and a connecting plate from top to bottom. The mounting plate is equipped with the stamping cylinder. The telescopic end of the stamping cylinder is fixed to the top of the connecting plate to drive the connecting plate to move up and down along the axial direction of the guide post. The bottom of the connecting plate is detachably equipped with the stamping head, which is adapted to the die.

[0008] By adopting the above technical solutions, the modular assembly design of the base plate, stamping cylinder, guide pillars, die, and stamping head, along with the stable guidance of the connecting plate by the four guide pillars, ensures precise axial movement of the stamping head and avoids part deformation caused by off-center loading. The detachable mounting structure of the die and stamping head allows for quick replacement of dies of different specifications to meet the stamping requirements of various bracket parts, greatly improving the equipment's versatility and production flexibility. The layered fixing design of the mounting plate and connecting plate allows the driving force of the stamping cylinder to be directly transmitted to the stamping head, reducing force transmission loss and improving stamping efficiency and forming accuracy.

[0009] Furthermore, a limiting post is provided on the top of the base plate, and the limiting post is detachably installed on the base plate by bolts.

[0010] By adopting the above technical solution, the limiting post added to the top of the base plate can be detachably installed by bolts. On the one hand, the installation height can be adjusted according to different die thicknesses to accurately limit the downward limit position of the connecting plate and avoid excessive contact between the stamping head and the die, which would cause damage to the mold. On the other hand, the limiting post and the guide post work together to form double protection to prevent overtravel problems caused by cylinder malfunction, improve the safety of equipment operation, and ensure the consistency of each stamping stroke, thereby reducing part size deviation.

[0011] Furthermore, the base plate is also provided with two symmetrically arranged die positioning blocks and limiting blocks; the die positioning blocks are installed on the base plate by bolts, and the die positioning blocks and the base plate enclose a positioning groove that allows the die to be inserted; the limiting blocks are installed on the base plate by bolts and are located at the same end of the two die positioning blocks.

[0012] By adopting the above technical solution, two symmetrically arranged die positioning blocks and the base plate form a positioning groove. Combined with the design of the end limiting block, the die can be quickly inserted and accurately positioned, avoiding alignment errors during manual installation. The positioning block and the limiting block are fixed by bolts, which makes it easy to adjust the position according to the die size and adapt to the production needs of different specifications of parts. The three work together to keep the die stable during the stamping process, prevent burrs or deformation of parts caused by lateral displacement, and improve the product qualification rate.

[0013] Furthermore, the bottom of the connecting plate is provided with two stamping head positioning blocks; the stamping head positioning blocks are installed above the die positioning blocks by bolts, and the stamping head positioning blocks and the connecting plate form a mounting groove that allows the stamping head to be inserted; the stamping head is installed in the mounting groove by bolts and is located above the die.

[0014] By adopting the above technical solution, the stamping head positioning block at the bottom of the connecting plate is installed correspondingly to the die positioning block, ensuring that the axes of the stamping head and the die coincide, avoiding die wear or part scrap caused by eccentric stamping; the mounting groove structure enclosed by the positioning block and the connecting plate makes it possible to disassemble and assemble the stamping head without adjusting the overall structure, shortening the replacement time; the design of the stamping head being located directly above the die ensures that the impact force acts perpendicularly on the workpiece, further improving the forming accuracy and die life.

[0015] Furthermore, clamping devices are provided on both sides of the limiting block. The clamping devices include a clamping cylinder, a positioning plate, a rotating plate, and a clamping head. The clamping cylinder is installed on the base plate, and the positioning plate is installed on the limiting block by bolts. The rotating plate is hinged to the telescopic end of the clamping cylinder, the clamping head is fixed to the rotating plate, and the rotating plate is rotatably installed on the positioning plate.

[0016] By adopting the above technical solution, the clamping devices on both sides of the limiting block can automatically press the workpiece onto the die surface before stamping through clamping cylinders, rotating plates, and clamping heads, replacing manual positioning, improving production efficiency and reducing operational risks; the design of the rotating plate hinged to the positioning plate allows the clamping head to adapt to workpieces of different thicknesses, expanding the applicability of the equipment; the layout of the clamping cylinder being installed on the base plate and the positioning plate being fixed to the core of the limiting block ensures stable clamping force without interfering with the stamping stroke, improving the overall compactness of the structure.

[0017] Furthermore, the clamping head is located above the cavity mold, and the outer periphery of the clamping head is fitted with a rubber sleeve.

[0018] By adopting the above technical solution, the rubber sleeve on the outer periphery of the clamping head directly contacts the workpiece, which can avoid scratches caused by hard contact between the metal clamping head and the workpiece surface, and protect the appearance quality of the product; the elastic properties of the rubber material can absorb the small vibrations during the stamping process and reduce the workpiece displacement error; at the same time, the sleeve can increase the friction and prevent the workpiece from slipping during stamping, further improving the clamping stability, which is especially suitable for processing thin plates or bracket parts with easily deformable surfaces.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model achieves precise axial guidance of the stamping head through a layered fixing structure of at least four guide posts on the base plate, mounting plate, and connecting plate. Combined with the detachable installation design of the die and stamping head, it not only ensures stamping accuracy but also improves die replacement efficiency and enhances equipment versatility.

[0021] 2. This utility model forms a positioning groove by enclosing the die positioning block and the base plate, and combined with the arrangement of the end limiting blocks, it realizes the rapid insertion and precise positioning of the die, prevents the die from lateral displacement during the stamping process, and improves the product forming stability.

[0022] 3. This utility model ensures that the axes of the stamping head and the die are aligned by corresponding installation of the stamping head positioning block and the die positioning block and enclosing the installation groove structure, thereby avoiding die wear caused by eccentric stamping and shortening the stamping head replacement time.

[0023] 4. This utility model achieves automatic workpiece clamping while avoiding surface scratches by using the hinged structure of the rotating plate and the positioning plate in the clamping device on both sides of the limiting block, combined with the rubber sleeve design on the outer periphery of the clamping head. It is suitable for workpieces of different thicknesses and improves clamping stability. Attached Figure Description

[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As can be seen, the present invention relates to a stamping forming device for fire extinguisher bracket parts. A base plate 1 is a basic load-bearing component, with at least four guide columns 3 mounted on its top. From top to bottom, a mounting plate 6 and a connecting plate 7 are fixed to the top of each guide column 3. The telescopic end of a stamping cylinder 2 fixed on the mounting plate 6 is connected to the connecting plate 7, causing the connecting plate 7 to move axially along the guide columns 3. A stamping head 5 is detachably mounted on the bottom of the connecting plate 7 via a mounting groove formed by two stamping head positioning blocks 11 enclosing the connecting plate 7. The stamping head 5 is located directly above and fitted to the die 4. Two symmetrically arranged die positioning blocks 9 enclose the base plate 1 to form a... A positioning groove is formed, and the die 4 can be detachably inserted into the positioning groove. One end of the positioning groove is provided with a limiting block 10 bolted to the base plate 1. The top of the base plate 1 is also provided with a limiting post 8 bolted to it. Clamping devices 12 are installed on both sides of the limiting block 10. The clamping cylinder 121 is fixed to the base plate 1, and the positioning plate 122 is bolted to the limiting block 10. One end of the rotating plate 123 is hinged to the telescopic end of the clamping cylinder 121, and the other end is rotatably installed on the positioning plate 122. The clamping head 124 fixed on the rotating plate 123 is located above the die 4 and is fitted with a rubber sleeve 125 on its outer periphery. The stamping head positioning block 11 and the die positioning block 9 are arranged vertically and vertically respectively.

[0033] In one embodiment, refer to Figure 2It can be seen that at least four guide posts 3 are vertically fixed on the base plate 1 to provide rigid support and axial guidance for the mounting plate 6 and the connecting plate 7; two symmetrically arranged die positioning blocks 9 are bolted to the surface of the base plate 1, which together with the base plate form a positioning groove. The die 4 can be detachably inserted into the groove. One end of the positioning groove is fixed with a limit block 10 by bolts to achieve rapid positioning and lateral limitation of the die 4, preventing the die from shifting during stamping; the top of the base plate 1 is also bolted with a limit post 8, the height of which can be adjusted according to the thickness of the die 4, to limit the downward limit position of the connecting plate 7 and avoid over-stroke stamping that could damage the mold; clamping devices 12 are symmetrically arranged on both sides of the limit block 10, including clamping cylinders. 121 is fixed to the base plate 1, and the positioning plate 122 is bolted to the limiting block 10. One end of the rotating plate 123 is hinged to the telescopic end of the clamping cylinder 121, and the other end is rotatably connected to the positioning plate 122 through a pin. The clamping head 124 fixed at the end of the rotating plate 123 is located above the die 4, and is fitted with a rubber sleeve 125 on its outer periphery. During operation, the clamping cylinder 121 drives the rotating plate 123 to rotate, which drives the clamping head 124 to press down and press the workpiece against the surface of the die 4. The rubber sleeve 125 prevents the workpiece from being scratched and increases friction. After stamping, the clamping cylinder 121 resets and releases the workpiece. The overall structure ensures stamping accuracy and operational safety through the coordinated action of mechanical positioning and pneumatic clamping.

[0034] In one embodiment, refer to Figure 3 As can be seen, the connecting plate 7, as the core component for transmitting stamping power and installing stamping actuators, is fixedly connected at its top to the telescopic end of the stamping cylinder 2, and at its bottom, the stamping head 5 is detachably assembled through the mounting groove formed by the two stamping head positioning blocks 11 and itself. The specific assembly relationship and working principle are as follows: the connecting plate 7 is fixed to the mounting plate 6 in layers through the guide post 3. The guide post 3 passes through the guide hole of the connecting plate to form a sliding fit, ensuring that the connecting plate moves stably along the axial direction when the stamping cylinder 2 is driven; the stamping head positioning block 11 at the bottom is installed on the die positioning block 9 directly above it by bolts, and the two form a positioning reference with the upper and lower axes coinciding. The stamping head 5, inserted into the mounting slot, is precisely aligned with the die 4 after being fixed by bolts. During operation, the driving force of the stamping cylinder 2 is directly transmitted to the stamping head 5 via the connecting plate 7. The rigid guidance of the guide column 3 prevents off-center loading. Combined with the correspondence between the stamping head positioning block 11 and the die positioning block 9, it ensures that the stamping head 5 acts perpendicularly to the workpiece, achieving high-precision forming. Its functions are: to shorten the stamping head 5 replacement time and improve equipment changeover efficiency through modular design; to reduce energy loss and increase stamping speed through layered force transmission structure; to reduce part size deviation through precise positioning mechanism; and to adapt to different specifications of stamping heads to meet diverse production needs.

[0035] In one embodiment, refer to Figure 4It can be seen that the limiting block 10 on the base plate 1 cooperates with the two symmetrically arranged die positioning blocks 9 to achieve the positioning of the die 4: the die positioning blocks 9 and the base plate 1 enclose to form a positioning groove. After the die 4 is inserted, one end of it is attached to the limiting block 10. The limiting block 10 restricts the lateral displacement of the die 4. At the same time, the die positioning blocks 9 position the die 4 laterally from both sides. The three together constitute the rigid positioning system of the die 4. The clamping process of the clamping device 12 is as follows: when the clamping cylinder 121 drives the telescopic end to extend, it drives the rotating plate 123 to rotate downward around the rotation axis on the positioning plate 122, so that the clamping head 124 fixed at the end of the rotating plate 123 is pressed vertically down to the surface of the die 4. The clamping is achieved by the friction between the rubber sleeve 125 and the die 4. Conversely, when the cylinder retracts, the rotating plate 123 flips up to release the die 4. Steps for replacing die 4: First, control the clamping cylinder 121 to reset so that the clamping head 124 is released. Unscrew the fixing bolts on the die positioning block 9 or the limit block 10. Pull the old die 4 out of the positioning groove, insert the new die 4 and make it fit with the limit block 10. After tightening the bolts, start the clamping device 12 to complete the fixation. Steps for replacing stamping head 5: Turn off the air source of the stamping cylinder 2, unscrew the bolts fixing the stamping head 5 on the stamping head positioning block 11, take the old stamping head 5 out of the mounting groove, install the new stamping head 5 and ensure that it is aligned with the axis of the die 4. After tightening the bolts, test run the stamping cylinder 2 to confirm the position accuracy.

[0036] Working principle: First, a positioning groove is formed on the base plate 1 by the positioning block 9 and the limiting block 10 of the die cavity. The die cavity 4 is inserted and fixed by the clamping device 12. Before stamping, the clamping cylinder 121 drives the rotating plate 123 to rotate, so that the clamping head 124 presses down on the workpiece and increases the friction through the rubber sleeve 125. After the stamping cylinder 2 is started, its telescopic end pushes the connecting plate 7 to move downward along the guide column 3, which drives the stamping head 5 at the bottom to act vertically on the workpiece in the die cavity 4. When the connecting plate 7 contacts the limiting column 8 on the base plate 1, it stops moving downward and the stamping is completed. Then the stamping cylinder 2 resets and drives the stamping head 5 to move upward. At the same time, the clamping cylinder 121 retracts and causes the rotating plate 123 to flip up and release the workpiece. By changing the die cavity 4 and the stamping head 5 of different specifications, the stamping production of various parts can be realized. The whole process ensures stamping accuracy and operation safety through the synergistic effect of mechanical positioning and pneumatic control.
