Description

Technical Field

[0001] This invention relates to the field of communication cabinet processing equipment technology, and in particular to a communication cabinet processing device. Background Technology

[0002] As the core structural support for communication base stations, data centers, and server room equipment, communication cabinets are primarily constructed from a large quantity of sheet metal through processes such as stamping, bending, and welding. Among these processes, stamping is crucial in determining the precision, strength, and production efficiency of the cabinet sheet metal. With the ongoing construction of 5G networks and the expansion of data centers, the market demand for communication cabinets continues to grow, placing higher demands on the automation level and production capacity of the stamping process.

[0003] Communication cabinet panels (such as side panels, door panels, and back panels) are typically large-sized metal sheets, generally over 1 meter in length, with some reaching 2 meters. Each sheet is heavy and requires high surface quality. Currently, there are still many shortcomings in the stamping process for these large-sized panels: Most production lines rely primarily on manual loading and unloading, resulting in high labor intensity, slow cycle times, and significant safety hazards. Some automated production lines use independent robotic arms or conveyor systems for loading and unloading, but these are expensive, complex to debug, and require electrical signal coordination with the stamping machine, making them prone to issues like asynchronous cycles and idle runs. Large sheet metal sheets have a large area and high frictional resistance, making them susceptible to skewing, jamming, or even complete blockage with conventional conveying methods, and easily scratched surfaces. Pre-stamping positioning typically uses independent cylinder drives, requiring additional air sources and control systems, increasing cost and complexity, and making precise synchronization between positioning and stamping timing difficult. After stamping, the formed sheet metal easily embeds into the bottom mold cavity, requiring an additional demolding mechanism to eject it before it is removed by the unloading mechanism. The demolding and unloading processes are independent and poorly coordinated, further reducing production efficiency. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a communication cabinet processing device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a communication cabinet processing device, comprising a support platform for support, a lower mold assembly disposed on the support platform, a column connected to the support platform, a top plate connected to the upper end of the column, a hydraulic cylinder for providing stamping power disposed on the top plate, and a top mold assembly connected to the output end of the hydraulic cylinder for cooperating with the lower mold assembly to stamp the cabinet panel. A support frame is disposed on one side of the support platform, and a feeding mechanism for stacking and pushing the cabinet panel to be stamped, and an auxiliary assembly for conveying the cabinet panel to the stamping station are disposed on the support frame. Pushing components for pushing the stamped cabinet panel out of the station are also disposed on both sides of the feeding mechanism.

[0006] Its beneficial effects are that the five processes of feeding, positioning, stamping, demolding and unloading are deeply integrated through mechanical linkage. Each action is naturally synchronized with the stamping cycle, without the need for manual intervention. This eliminates the waiting time for independent feeding and unloading, greatly compresses the cycle time of a single station, and realizes unmanned continuous operation.

[0007] In the above scheme, preferably, the feeding mechanism includes a guard plate mounted on a support frame, a sprocket and chain assembly on the guard plate, and a storage box for stacking cabinet panels connected to the support frame via support columns. The storage box has a sliding groove, and several movable balls are arranged on its bottom wall. A fixing block is connected to the sprocket and chain assembly, and a pusher for pushing the cabinet panels is connected to the fixing block. A connecting rod connects two pushers.

[0008] Its beneficial effects are that the movable ball on the bottom wall of the storage box converts sliding friction into rolling friction, and the initial push of the push column and the subsequent conveying of the friction roller form a two-stage conveying, avoiding jamming and skewing during long-distance conveying of large plates; the elastic clamping of the springs adapts to different thicknesses and does not damage the surface; the positioning block extends along the inclined surface and generates a dual positioning force of centripetal centering and downward clamping, ensuring accurate stamping position and significantly improving the yield.

[0009] In the above scheme, preferably, the push column is located in the first slide groove and can slide along it, the bottom of the storage box is provided with a discharge hole for discharging a single cabinet panel, the discharge hole is connected to the first slide groove, and the sprocket and chain assemblies on both sides are synchronously connected through a drive shaft.

[0010] In the above scheme, preferably, a motor is installed in the support frame through a support plate, and the output end of the motor is connected to the sprocket and chain assembly through a transmission component to drive the push column to reciprocate and push the cabinet panel.

[0011] In the above scheme, preferably, the pushing assembly includes a slide rail mounted on a support column, a fixed plate connected to one end of the slide rail, a slider slidably mounted on the slide rail, a vertical plate connected to the slider, a spring and a push rod for pushing the cabinet panel disposed between the vertical plate and the fixed plate, and a push block connected to the end of the push rod. A pull rope is connected to the vertical plate, and the pull rope is connected to the top mold assembly via a guide wheel mounted on the storage box, so that the push block is driven to push the material out through the return stroke of the top mold assembly.

[0012] Its advantages are that the material feeding is linked with the pull rope and the top mold, the positioning is supplied with air by the downward compression airbag of the stamping, the demolding is linked with the return lifting plate of the top mold, and the feeding and auxiliary conveying share the same motor and are synchronously driven by the toothed belt. There is no need to configure separate independent motors, cylinders and complex control systems. The structure is simple, there are fewer parts, and both manufacturing costs and maintenance costs are reduced.

[0013] In the above scheme, preferably, the auxiliary component includes a C-shaped plate set on the support platform, a friction roller is configured on the lower part of the C-shaped plate through a connecting block, a friction roller is slidably configured on the upper part of the C-shaped plate through a connecting block, and a spring for pressing the cabinet plate is provided between the connecting block and the C-shaped plate. The friction roller is synchronously connected to the transmission assembly through the transmission assembly, so as to realize that the feeding and auxiliary conveying operate at the same rhythm.

[0014] In the above scheme, preferably, the top mold assembly includes a guide column disposed on a support platform, a frame slidably disposed on the guide column, and a pressing mold for stamping the cabinet panel disposed at the lower part of the frame. A pressure plate and a pull rod are connected to the frame, and a lifting plate for linkage demolding is connected to the lower end of the pull rod.

[0015] In the above scheme, preferably, the lower mold assembly includes a base plate 1 disposed on a support platform, a bottom mold connected to the base plate 1, and an inclined surface provided on the inner side wall of the bottom mold; a spring 3 and an airbag corresponding to the pressure plate are disposed on the bottom mold via a connecting plate 1, a disc is connected to the upper end of the spring 3, a demolding assembly is disposed in the middle of the bottom mold, and a positioning assembly for positioning the cabinet panel is disposed on the inclined surface, the positioning assembly is connected to the airbag so that the positioning assembly is driven to clamp and position by the pressure plate compressing the airbag.

[0016] In the above scheme, preferably, the positioning component includes a square tube disposed within the bottom mold, the square tube being connected to the airbag via a bend. A second sliding groove is provided on the inclined surface, and a positioning block for positioning the cabinet panel is slidably disposed within the second sliding groove. A fifth spring is disposed between the positioning block and the bottom mold, and a piston rod connected to the square tube is connected to the positioning block to push the positioning block out for positioning by air supply from the airbag.

[0017] In the above scheme, preferably, the demolding component includes a second base plate disposed in the middle of the bottom mold, a second connecting plate connected to the lower end of the second base plate, an inverted platform fixed to the support platform slidably disposed on the second connecting plate, and a force-bearing plate connected to the lower end of the second connecting plate; The connecting plate 2 has a cavity, and a gasket and spring 4 are fixed to the inverted platform inside the cavity.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1:

[0030] See Figures 1-10 A communication cabinet processing device includes a support platform 1 for support, a lower die assembly 6 on the support platform 1, a column 2 connected to the support platform 1, a top plate 3 connected to the upper end of the column 2, a hydraulic cylinder 4 for providing stamping power on the top plate 3, and a top die assembly 5 connected to the output end of the hydraulic cylinder 4 for cooperating with the lower die assembly 6 to stamp a cabinet panel 11; a support frame 10 is arranged on one side of the support platform 1, and a feeding mechanism 8 for stacking and pushing the cabinet panel 11 to be stamped is arranged on the support frame 10, as well as an auxiliary assembly 7 for conveying the cabinet panel 11 to the stamping station. Pushing assemblies 9 are also arranged on both sides of the feeding mechanism 8 for pushing the stamped cabinet panel 11 out of the station.

[0031] The support platform 1 provides the installation reference and support for the entire device. It has a rectangular frame structure and is placed horizontally on the ground. The lower die assembly 6 is fixedly installed in the middle of the upper end of the support platform 1 as the lower die part for stamping. The four corners of the upper end of the support platform 1 are vertically connected to the columns 2. The upper ends of the four columns 2 are connected to a horizontally arranged top plate 3, forming a portal frame structure. Three hydraulic cylinders 4 are arranged at equal intervals along the length of the top plate 3, and together provide the pressure required for stamping. The output ends of the three hydraulic cylinders 4 all extend through the surface of the top plate 3 to the lower part of the top plate 3, and are connected to the top die assembly 5. The hydraulic cylinders 4 drive the top die assembly 5 to move up and down to complete the stamping action. A support frame 10 is fixedly connected to the right end of the support platform 1. The support frame 10 has a frame structure and its height is adapted to the support platform 1. A feeding mechanism 8 for feeding materials is fixedly installed on the upper part of the support frame 10. Several cabinet panels 11 to be stamped are stacked inside the feeding mechanism 8. An auxiliary feeding component 7 is connected to the left side of the feeding mechanism 8 to smoothly transport the cabinet panels 11 from the feeding mechanism 8 to the stamping station. Pushing components 9 for unloading after stamping are also connected to both sides of the feeding mechanism 8 to push the stamped cabinet panels 11 out of the stamping station.

[0032] The feeding mechanism 8 includes a guard plate 81 mounted on a support frame 10. A sprocket and chain assembly 82 is mounted on the guard plate 81. A storage box 84 for stacking cabinet panels 11 is connected to the support frame 10 via a support column 83. A sliding groove 85 is provided on the storage box 84. Several movable balls 86 are mounted on the bottom wall of the storage box 84.

[0033] A fixing block 87 is connected to the sprocket and chain assembly 82, and a push post 88 for pushing the cabinet panel 11 is connected to the fixing block 87. A connecting rod 89 is connected between the two push posts 88.

[0034] The push column 88 is located in the slide groove 85 and can slide along it. The bottom of the storage box 84 is provided with a discharge hole for discharging a single cabinet plate 11. The discharge hole is connected to the slide groove 85. The sprocket and chain assemblies 82 on both sides are synchronously connected through a drive shaft.

[0035] The storage box 84 serves as a stacking container for the cabinet panels 11. Its internal dimensions are adapted to the cabinet panels 11, allowing the cabinet panels 11 to be stacked horizontally inside. The discharge hole at the bottom left end of the storage box 84 is only slightly larger than the thickness of a single cabinet panel 11, ensuring that only the bottommost cabinet panel 11 can pass through when the pusher 88 pushes it, achieving single-pane separation and avoiding the discharge of multiple panels at once. The array of movable balls 86 on the bottom wall of the storage box 84 converts the sliding friction between the cabinet panel 11 and the bottom of the box into rolling friction, significantly reducing the resistance when pushing large cabinet panels 11, allowing the pusher 88 to smoothly push the cabinet panels 11 with a smaller thrust.

[0036] A motor 802 is installed inside the support frame 10 via a support plate 801. The output end of the motor 802 is connected to the sprocket and chain assembly 82 via a transmission component 803 to drive the push column 88 to reciprocate to push the cabinet panel 11.

[0037] The sprocket and chain assembly 82 serves as the driving carrier for the pusher column 88. When the chain rotates, it drives the fixed block 87 and the pusher column 88 to perform horizontal cyclical movement along the slide groove 85. The two pusher columns 88 are connected as one unit by the connecting rod 89, and the left and right sprockets rotate synchronously through the transmission shaft, ensuring that the two pusher columns 88 push the cabinet plate 11 synchronously, preventing the cabinet plate 11 from tilting and jamming due to uneven force. The motor 802 drives the sprocket to rotate through the transmission assembly 803, toothed disc and toothed belt. The toothed belt drive has the characteristics of precise transmission ratio, smooth operation and low noise, and is suitable for precise rhythm control of step feeding of large plates.

[0038] The material pushing assembly 9 includes a slide rail 91 mounted on a support column 83. One end of the slide rail 91 is connected to a fixed plate 96. A slider 92 is slidably mounted on the slide rail 91. A vertical plate 93 is connected to the slider 92. A spring 98 and a push rod 97 for pushing the cabinet panel 11 are arranged between the vertical plate 93 and the fixed plate 96. A push block 99 is connected to the end of the push rod 97. A pull rope 94 is connected to the vertical plate 93. The pull rope 94 is connected to the top mold assembly 5 via a guide wheel 95 mounted on the storage box 84, so that the push block 99 is driven to push the material through the return stroke of the top mold assembly 5.

[0039] The pusher assembly 9 uses the upward movement of the top die assembly 5 as its power source. The vertical motion is converted into a horizontal pushing action via the pull rope 94. This eliminates the need for an additional drive motor or cylinder, resulting in a simple structure that is naturally synchronized with the stamping cycle. When the top die assembly 5 moves upward, the pull rope 94 is redirected and tensioned by the guide wheel 95, pulling the vertical plate 93 to slide to the left along the slide rail 91. The vertical plate 93 compresses the spring 98 and pushes the push rod 97 to the left. The push block 99 at the end of the push rod 97 pushes the demolded cabinet panel 11 from the stamping station to the left. When the top die assembly 5 moves downward, the pull rope 94 relaxes, the spring 98 rebounds, pushing the vertical plate 93 to the right and resetting. The push rod 97 and push block 99 then retract, preparing for the next push.

[0040] Spring 98 is sleeved on the outside of push rod 97, providing both restoring elasticity and radial support and guidance for push rod 97, preventing it from bending and wobbling. Push block 99 has a large contact area with the side of cabinet panel 11, which can disperse the pushing force and avoid local deformation of large-sized cabinet panel 11. Guide wheel 95 changes the direction of pull rope 94, so that pull rope 94 smoothly transitions from the vertical movement of frame 52 to the horizontal movement of upright plate 93, reducing friction and jamming.

[0041] The auxiliary component 7 includes a C-shaped plate 71 mounted on the support platform 1. A friction roller 73 is mounted on the lower part of the C-shaped plate 71 via a connecting block 72, and a friction roller 76 is slidably mounted on the upper part of the C-shaped plate 71 via a connecting block 74. A spring 75 for pressing the cabinet panel 11 is provided between the connecting block 74 and the C-shaped plate 71. The friction roller 73 is synchronously connected to the transmission component 803 via a transmission component 77 to achieve synchronized operation of the feeding and auxiliary conveying processes.

[0042] Auxiliary component 7 and feeding mechanism 8 share the same motor 802 for drive. While transmission component 1 803 is running, it synchronously drives friction roller 1 73 to rotate through transmission component 2 77 toothed disc + toothed belt, so that the feeding rhythm of friction roller is completely consistent with the pushing rhythm of push column 88, avoiding the cabinet panel 11 from jamming or piling up at the junction due to asynchronous speed. After the cabinet panel 11 is sent out from storage box 84, it enters between friction roller 1 73 and friction roller 2 76. The two rollers rely on the clamping friction force to continue to transport cabinet panel 11 to the left to the stamping station. The cabinet panel 11 is transported in two stages: initial push by push column + continued feeding by friction roller. This ensures that large-size cabinet panel 11 always has driving force during long-distance transportation and will not stop halfway due to insufficient inertia or increased resistance.

[0043] Friction roller 76 is slidably mounted on C-shaped plate 71 via connecting block 74, and is provided with downward clamping force by spring 75. This allows friction roller 76 to automatically float up and down according to the thickness of cabinet panel 11, always maintaining a moderate clamping force on cabinet panel 11. The elastic clamping of spring 75 ensures sufficient friction to transport cabinet panel 11 without damaging the surface of the panel or causing excessive transport resistance due to excessive pressure. The open structure of C-shaped plate 71 positions the friction roller assembly on the transport path of cabinet panel 11 without obstructing the passage space of cabinet panel 11. The top mold assembly 5 includes a guide column 51 mounted on a support platform 1, a frame 52 slidably mounted on the guide column 51, and a pressing mold 53 for stamping the cabinet panel 11 disposed at the lower part of the frame 52. A pressure plate 54 and a pull rod 55 are connected to the frame 52, and a lifting plate 56 for linkage demolding is connected to the lower end of the pull rod 55.

[0044] The frame 52 slides up and down along the four corner guide posts 51. The guide posts 51 provide precise linear motion guidance for the frame 52, preventing the die 53 from deviating during the stamping process and ensuring consistent stamping depth throughout the large-size cabinet panel 11. The four pressure plates 54 on the front and rear ends of the frame 52 correspond vertically to the four discs 67 of the lower die assembly 6. Before the die 53 contacts the cabinet panel 11, the pressure plates 54 first contact the discs 67 and compress the airbags 65, triggering the positioning assembly 68 to first complete the positioning and clamping of the cabinet panel 11. Only then does the die 53 contact the cabinet panel 11 for stamping, forming a sequence of positioning followed by stamping. This ensures that the position of the cabinet panel 11 is fixed during stamping, preventing the sheet metal from shifting during the stamping process and causing a decrease in forming accuracy.

[0045] The tie rods 55 at the front and rear ends of the frame 52 move up and down synchronously with the frame 52. The lifting plate 56 at the lower end of the tie rod 55 is located directly below the force plate 697 of the demolding assembly 69. When the frame 52 moves upward after stamping, the lifting plate 56 moves upward and lifts the force plate 697. Through the connecting plate 692, the bottom plate 691 is driven to push the formed cabinet panel 11 out of the bottom mold 62, realizing the linkage between the demolding action and the return of the top mold, without the need for additional demolding drive. The tie rods 55 and lifting plates 56 at the front and rear ensure that the demolding force is evenly distributed in the front and rear direction of the cabinet panel 11, avoiding the large cabinet panel 11 from being tilted and stuck in the bottom mold 62 due to the force on one side.

[0046] The lower mold assembly 6 includes a base plate 61 mounted on a support platform 1, a bottom mold 62 connected to the base plate 61, and an inclined surface 63 on the inner side wall of the bottom mold 62. A spring 66 and an airbag 65 corresponding to the pressure plate 54 are mounted on the bottom mold 62 via a connecting plate 64. A disc 67 is connected to the upper end of the spring 66. A demolding assembly 69 is mounted in the middle of the bottom mold 62. A positioning assembly 68 for positioning the cabinet panel 11 is mounted on the inclined surface 63. The positioning assembly 68 communicates with the airbag 65 so that the pressure plate 54 compresses the airbag 65 to drive the positioning assembly 68 to clamp and position it.

[0047] The inner cavity shape of the bottom mold 62 is adapted to the shape required for stamping the cabinet panel 11. The inclined surface 63 of the inner side wall slopes inward from top to bottom. When the cabinet panel 11 is placed in, it slides into the inner cavity guided by the inclined surface 63, reducing the accuracy requirements for the alignment of the cabinet panel 11. Even if there is a slight deviation when the cabinet panel 11 is fed in, it can automatically slide into the correct position along the inclined surface. The inclined surface 63 also provides installation and sliding space for the positioning block 684 of the positioning component 68, so that when the positioning block 684 extends, it can apply a positioning force to the side of the cabinet panel 11 from the inclined surface direction.

[0048] Four sets of springs 66 at the front and rear ends of the bottom mold 62 are coaxially arranged with the airbag 65. The disc 67 is located at the top of the springs 66 and corresponds to the pressure plate 54. When the top mold moves downward, the pressure plate 54 presses down on the disc 67, the springs 66 are compressed to provide elastic cushioning, and at the same time the airbag 65 is compressed to transport the internal gas to the positioning component 68 through the bend pipe, driving the positioning block 684 to extend and complete the positioning. When the top mold moves upward, the pressure plate 54 disengages from the disc 67, the springs 66 rebound to reset the disc 67, the air pressure inside the airbag 65 decreases to form a negative pressure, and the positioning block 684 retracts under the action of the spring 685 to release the positioning. The airbag 65 serves as a gas source to provide power to the positioning component 68, and together with the springs 66, it forms an elastic buffer layer to absorb the impact when the pressure plate 54 presses down, avoiding rigid collisions that could damage the components.

[0049] The positioning component 68 includes a square tube 681 disposed within the bottom mold 62, which is connected to the airbag 65 via a bend. A second groove 683 is provided on the inclined surface 63, and a positioning block 684 for positioning the cabinet panel 11 is slidably disposed within the second groove 683. A spring 685 is disposed between the positioning block 684 and the bottom mold 62, and a piston rod 682 connected to the positioning block 684 and communicating with the square tube 681 is connected to the piston rod 682, so that the positioning block 684 can be pushed out for positioning by air supply from the airbag 65.

[0050] The positioning component 68 is powered by the gas generated by the compression of the airbag 65. It does not require additional cylinders or solenoid valves. The positioning is triggered by the downward movement of the stamping itself. The positioning action is naturally synchronized with the stamping action, and there is no problem of signal delay or asynchronous timing. When the airbag 65 is compressed, the gas enters the square tubes 681 around the bottom mold 62 through the curved tube. The square tubes 681 serve as air distribution channels, delivering the gas to each piston rod 682 simultaneously. The air pressure pushes the piston rods 682 to extend outward, which in turn pushes the positioning block 684 to slide outward along the second slide groove 683. After the positioning block 684 extends out of the inclined surface 63, it clamps and positions the cabinet panel 11 from all sides, fixing the cabinet panel 11 in a precise position before stamping.

[0051] The second slide 683 is arranged along the inclined direction of the slope 63, and the positioning block 684 extends along the inclined direction. Its positioning force has both a horizontal centripetal component and a vertical downward component, which can both push the cabinet panel 11 towards the center and press the cabinet panel 11 downward onto the bottom surface of the bottom mold 62, achieving a dual positioning effect of "centering + pressing". The fifth spring 685 is connected to the lower inner part of the positioning block 684. When the air bag 65 rebounds, the air pressure in the square tube 681 decreases, and the fifth spring 685 pulls the positioning block 684 inward. The piston rod 682 retracts accordingly, releasing the positioning of the cabinet panel 11 and making room for demolding and unloading. Each positioning block 684 is supplied with air from the same square tube 681, and the air pressure is uniform, ensuring that the positioning force in all directions is consistent and avoiding unilateral force deviation of the cabinet panel 11.

[0052] The demolding assembly 69 includes a second base plate 691 disposed in the middle of the bottom mold 62. A second connecting plate 692 is connected to the lower end of the second base plate 691. An inverted platform 693, which is fixed to the support platform 1, is slidably disposed on the second connecting plate 692. A force-bearing plate 697 is connected to the lower end of the second connecting plate 692. A cavity 694 is formed on the second connecting plate 692. A gasket 695, which is fixed to the inverted platform 693, and a fourth spring 696 are disposed in the cavity 694. A lifting plate 56 is located below the force-bearing plate 697, so that the lifting plate 56 can lift the force-bearing plate 697 through the return stroke of the top mold assembly 5 to achieve demolding.

[0053] The second base plate 691 serves as the bearing surface for the cabinet panel 11 during stamping. Its upper surface is flush with the bottom surface of the inner cavity of the bottom mold 62, ensuring a flat and stepless bottom support for the cabinet panel 11 during stamping. During stamping, the cabinet panel 11 is pressed onto the second base plate 691 by the die 53. The second base plate 691 moves downward to its lowest position against the elastic force of the fourth spring 696, with its upper surface flush with the bottom surface of the bottom mold 62. The cabinet panel 11 is then formed within the bottom mold 62. The inverted platform 693 is fixed to the upper end of the inner cavity of the support platform 1, serving as a guide sleeve for the sliding of the second connecting plate 692, ensuring that the second base plate 691 does not tilt during lifting and lowering, and also providing an installation reference for the shim 695 and the fourth spring 696. After stamping, the top die assembly 5 moves upward, and the frame 52 drives the lifting plate 56 upward through the tie rod 55. The lifting plate 56 lifts the force plate 697, and the force plate 697 drives the bottom plate 691 upward through the connecting plate 692, pushing the formed cabinet panel 11 out of the bottom die 62, so that the bottom surface of the cabinet panel 11 is higher than the upper surface of the bottom die 62, providing pushing space for the push block 99 of the pusher assembly 9. The fourth spring 696 is set in the cavity 694 of the connecting plate 692. The upper end is fixed to the inverted stage 693 through the gasket 695, and the lower end is connected to the bottom wall of the cavity 694. During stamping, the fourth spring 696 is stretched or compressed to store elastic potential energy. During demolding, the elastic force of the fourth spring 696 assists the lifting plate 56 to provide the ejection force, ensuring that the large-size cabinet panel 11 can be smoothly ejected from the bottom die 62, avoiding the cabinet panel 11 from getting stuck in the mold cavity due to insufficient demolding force. The cavity 694 is an elongated strip structure extending vertically, providing travel space for the connecting plate 692 to slide vertically relative to the inverted stage 693. The gasket 695 slides relative to the cavity 694, limiting the maximum lifting stroke of the connecting plate 692.

[0054] Its working principle or usage method is as follows: First, the motor 802 drives the sprocket and chain assembly 82 to move through the transmission assembly 803, which in turn drives the pusher 88 to slide along the slide groove 85 of the storage box 84, pushing out the bottom single cabinet plate 11 from the bottom discharge hole. The movable ball 86 changes the sliding friction into rolling friction, reducing the pushing resistance.

[0055] The motor 802 synchronously drives the friction roller 73 in the auxiliary component 7 to rotate through the transmission component 2 77. The friction roller 76, which is pressed by the spring 2 75, clamps the cabinet plate 11 and smoothly feeds the cabinet plate 11 to the stamping station.

[0056] Then, the hydraulic cylinder 4 drives the frame 52 of the top mold assembly 5 to move down along the guide column 51. The pressure plate 54 first presses down on the disc 67 and compresses the air bag 65. The gas pushes the piston rod 682 through the square tube 681, so that the positioning block 684 extends along the slide groove 683 to center and press the cabinet plate 11. Then, the pressure mold 53 and the bottom mold 62 cooperate to complete the stamping and forming. The bottom plate 691 moves down under pressure, and the spring 696 stores energy.

[0057] Finally, the frame 52 returns to the top, the pressure plate 54 disengages from the disc 67, and the positioning block 684 retracts and releases its positioning under the action of the spring 685; at the same time, the pull rod 55 drives the lifting plate 56 to rise and lift the force plate 697, so that the bottom plate 691 rises and pushes the formed cabinet plate 11 out of the bottom mold 62.

[0058] Example 2:

[0059] See Figures 1-10 This embodiment makes further improvements based on Embodiment 1, including a detection unit. After the cabinet panel 11 is stamped, it is pushed into the detection unit. The detection unit includes a roller brush with multiple cylindrical inflatable pistons evenly arranged on it. The pistons press against the stamped grooves on the surface of the cabinet panel 11 to detect the springback of the formed panel. Since the cabinet panel 11 is large, the detection unit is implemented by the roller brush sweeping along the panel surface. Multiple cylindrical inflatable pistons are evenly arranged on the roller brush. After the pistons press against the panel surface, the change in piston stroke or air pressure determines whether the formed groove is qualified.

[0060] The top mold assembly 5 also moves upward by pulling the push block 99 at the end of the push rod 97 through the pull rope 94, pushing the demolded cabinet panel 11 out of the stamping station and into the inspection unit. The inflatable piston column on the roller brush presses against the groove, and the piston stroke or air pressure change determines whether the forming springback is qualified.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
