Description

Technical Field

[0001] This utility model relates to the field of mechanical stamping equipment technology, and in particular to a stamping forming mechanism for a computer power supply housing. Background Technology

[0002] As an important protective and supporting component in computer hardware systems, computer power supply housings require the use of stamping equipment to cut and form metal sheets. In the current stamping production process of computer power supply housings, in order to meet the needs of mass production, the stamping equipment needs to maintain high-frequency reciprocating operations. However, existing stamping equipment often lacks complete auxiliary positioning devices and waste disposal devices when processing power supply housing sheets. When the stamping die contacts the sheet and applies a huge impact force, the sheet placed on the stamping table is prone to positional displacement or vibration due to the lack of effective lateral clamping and fixation. The displacement of the sheet can lead to the final power supply housing having substandard dimensional accuracy, and in severe cases, it can even lead to the scrapping of the sheet.

[0003] Meanwhile, irregular metal scraps are continuously generated during the stamping and cutting process. Existing stamping equipment allows these scraps to scatter directly around the stamping table or at the bottom of the equipment. The disorderly scattered scraps not only make the production site dirty and messy, but they are also very likely to bounce back and get stuck in the gaps of the stamping die, causing abnormal wear or jamming of the die. This forces operators to frequently stop the machine for manual cleaning, which not only increases the labor intensity of workers, but also seriously reduces the stamping production efficiency and continuity of computer power supply housings.

[0004] Therefore, this utility model proposes a computer power supply housing stamping mechanism to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology of computer power supply housing stamping mechanism, such as the lack of effective clamping and fixing of sheet metal during the stamping process, which easily leads to displacement and deformation, resulting in insufficient dimensional accuracy, and the difficulty in collecting and cleaning up stamping waste, which seriously affects production efficiency and environmental cleanliness, this utility model aims to provide a computer power supply housing stamping mechanism with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a computer power supply housing stamping forming mechanism, including: a stamping machine, a clamping mechanism installed on the stamping table of the stamping machine, a collecting mechanism installed on the bottom of the stamping machine, and a collecting groove installed on the bottom of the collecting mechanism.

[0007] The clamping mechanism includes a fixed base plate fixedly connected to the stamping table of the stamping machine. A slide rail 1 is fixedly connected to the left side of the top wall of the fixed base plate. A hydraulic push rod is installed on the right side of the top wall of the fixed base plate. A fixed plate is fixedly connected to the middle of the top wall of the fixed base plate. A slider 1 is fixedly connected to the front end of the hydraulic push rod through the fixed plate. The slider 1 is slidably connected to the slide rail 1. A fixed rod is fixedly connected to the top wall of the slider 1. A rotating plate is rotatably connected to the fixed rod. The other end of the rotating plate is rotatably connected to the top wall of the slider 2 through the fixed rod. A slide rail 2 is fixedly connected to the left side of the fixed base plate. The slider 2 is slidably connected to the slide rail 2. A clamping plate is fixedly connected to the left side of the outer wall of the slider 2.

[0008] The collection mechanism includes a transport housing installed below the stamping area of ​​the stamping machine. A servo motor is installed on the left side of the outer wall of the transport housing. A sprocket is fixedly connected to the output end of the servo motor. A chain is meshed with the sprocket. A sprocket is meshed with the other end of the inner wall of the chain. A conveyor belt is fixedly connected to the outer wall of the chain. A baffle is fixedly connected to the outer wall of the conveyor belt.

[0009] Furthermore, the hydraulic push rod of the clamping mechanism is combined with the slider through the connecting rod rotating plate to form a mechanical transmission structure that converts linear thrust into lateral clamping force, so as to accurately clamp and position the sheet metal in the stamping area. At the same time, the servo motor of the collecting mechanism drives the baffle on the conveyor belt to circulate through the chain drive, so as to transport the scrap generated by stamping from the inside of the transport shell to the external collection tank, thus forming a complete stamping unit with stable clamping and automatic waste discharge functions.

[0010] Preferably, the top wall of the transport housing is provided with a transport trough, which is located on both sides of the stamping area of ​​the press. The transport trough vertically penetrates the top wall of the transport housing and communicates with the interior of the transport housing. The transport trough is located directly above the conveyor belt. This layout ensures that the stamping waste can accurately fall into the conveyor belt from both sides of the table.

[0011] Preferably, a connecting rod is fixedly connected to the right side of the outer wall of both sprocket one and sprocket two. The connecting rod is rotatably connected to the inner wall of the transport housing, and another set of sprocket one and sprocket two is fixedly connected to the other end of the connecting rod. The output end of the servo motor drives sprocket one to rotate through the connecting rod. This double-sided sprocket structure enhances the balance and load-bearing capacity of the conveyor belt.

[0012] Preferably, the transport casing is equipped with two sets of chains arranged parallel to each other. The conveyor belt is fixedly connected between the two sets of chains and extends along the length of the transport casing. The two sets of parallel chains provide uniform tension and support for the conveyor belt, effectively preventing the conveyor belt from deforming or running off-center under heavy load.

[0013] Preferably, the output end of the servo motor passes through the outer wall of the transport housing and is connected to the sprocket with one key. The servo motor is fixedly mounted on the surface of the outer wall of the transport housing by bolts, and the axis of the servo motor coincides with the axis of the sprocket. This compact installation method simplifies the transmission structure and ensures the reliability of power transmission.

[0014] Preferably, multiple sets of baffles are arranged in an array at equal intervals along the length of the conveyor belt. The baffle surface is perpendicular to the outer surface of the conveyor belt, and the width of the baffle is adapted to the width of the conveyor belt. The pushing force of the baffles is used to forcibly remove scraps, which is particularly suitable for conveying irregular large pieces of waste.

[0015] Preferably, the center of the fixing plate has a guide hole for the extension end of the hydraulic push rod to pass through. The bottom end of the fixing plate is vertically welded to the top wall of the fixing base plate, and the fixing plate is located between the slide rail and the main body of the hydraulic push rod. The fixing plate provides additional support and guidance for the hydraulic push rod.

[0016] Preferably, slide rail one is set along the length direction of the fixed base plate, slide rail two is set along the width direction of the fixed base plate, and the extension direction of slide rail one is perpendicular to the extension direction of slide rail two. Slider two converts the longitudinal movement of slider one into lateral movement through a rotating plate. This vertical guide rail layout is the core geometric basis for realizing opposing clamping.

[0017] Preferably, the two ends of the rotating plate are hinged to the top walls of slider one and slider two respectively through fixed rods. Slider one and slider two are slidably engaged with slide rail one and slide rail two respectively through dovetail groove structure. The hinged connection gives the linkage structure the necessary degree of freedom, while the dovetail groove structure provides high-precision sliding guidance.

[0018] Preferably, the collection trough is movably placed below the bottom wall of the transport housing, with the opening of the collection trough located directly below the output end of the conveyor belt, and the size of the collection trough is larger than the size of the transport trough. The movable placement design makes it convenient for operators to replace or empty the collected waste in a timely manner.

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

[0020] 1. This utility model, by installing a clamping mechanism driven by a hydraulic push rod on the stamping machine table, and utilizing the linkage structure formed by the slider and the rotating plate, converts the longitudinal extension and retraction motion of the hydraulic push rod into the lateral opening and closing motion of the clamping plate, thereby stably clamping the computer power supply shell sheet metal. This solves the problem in the prior art that the sheet metal is prone to displacement or deformation due to force during the stamping process, resulting in insufficient dimensional accuracy, and achieves the effect of effectively improving the product forming quality and enhancing production stability.

[0021] 2. This utility model solves the problems of large amounts of metal waste scattering and causing mold jamming and damage, as well as low efficiency of manual cleaning, by setting a collection mechanism including a transport shell and conveyor belt at the bottom of the stamping machine. The servo motor drives the sprocket chain to drive the conveyor belt and baffle to circulate and scrape the stamping scrap falling through the transport trough to the external collection trough.

[0022] 3. This utility model solves the problem of slippage or belt deviation that occurs when conventional belt conveyors transport irregularly shaped and sharp-edged metal scrap by setting vertically distributed baffles on the surface of the conveyor belt and adopting a transmission support structure with parallel double chains. This achieves the effect of enhancing the scrap grabbing ability and significantly improving the operational reliability of the waste discharge system. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0032] Example:

[0033] Please refer to Figures 1 to 6 This utility model provides a computer power supply housing stamping mechanism, which aims to solve the structural defects in the prior art where the sheet metal is prone to displacement and deformation during the stamping process, resulting in insufficient dimensional accuracy, and large pieces of scrap generated during stamping are prone to scattering and jamming the mold, and are difficult to collect and clean.

[0034] Please refer to Figure 1 and Figure 2 A computer power supply housing stamping forming mechanism includes a stamping machine 1, a clamping mechanism 2 installed on the stamping table of the stamping machine 1, a collecting mechanism 3 installed at the bottom of the stamping machine 1, and a collecting trough 4 installed at the bottom of the collecting mechanism 3. The stamping machine 1 is used to provide the power required for stamping processing and serves as the mounting base for the overall equipment. The clamping mechanism 2 clamps and fixes the sheet metal placed on the stamping table in both directions through mechanical linkage. The collecting mechanism 3 is used to directionally transport the waste generated during the stamping process from the stamping area to the outside. The collecting trough 4 is movably placed below the collecting mechanism 3 for collecting waste.

[0035] Please refer to Figure 2 , Figure 4 and Figure 5The clamping mechanism 2 includes a fixed base plate 201 bolted to the stamping table of the stamping machine 1. A slide rail 202 extending along the length of the fixed base plate 201 is fixedly connected to the left side of the top wall of the fixed base plate 201 by screws. A hydraulic push rod 204 is mounted on the right side of the top wall of the fixed base plate 201 via a bracket. A fixed plate 205 is vertically fixedly connected to the middle of the top wall of the fixed base plate 201 by welding. A guide hole is provided at the center of the fixed plate 205 for the telescopic end of the hydraulic push rod 204 to pass through. The front end of the hydraulic push rod 204 passes through the fixed plate 205 and is fixedly connected to a slider 203 via a flange. The bottom of the slider 203 has a groove that matches the slide rail 202, thus slidably connecting it to the outer wall of the slide rail 202. A fixed rod 207 is welded and fixedly connected to the top wall of the slider 203. A rotating plate 206 is rotatably connected to the outer wall of the fixed rod 207 via a bearing. The other end of the rotating plate 206 is hinged to the top wall of the second slider 208 via another fixed rod 207. A second slide rail 209 extending along the width of the fixed base plate 201 is fixedly connected to the left side of the fixed base plate 201 via screws. The second slide rail 209 is perpendicular to the first slide rail 202. The bottom of the second slider 208 is provided with a sliding groove so that it is slidably connected to the outer wall of the second slide rail 209. A clamping plate 210 for contacting the plate is fixedly connected to the left side of the outer wall of the second slider 208 via screws. The first slider 203 is driven to move longitudinally by the hydraulic push rod 204. The second slider 208 is pushed to move laterally on the second slide rail 209 by the linkage transmission of the rotating plate 206, thereby driving the clamping plate 210 to clamp and release the plate.

[0036] Please refer to Figure 3 and Figure 6 The collection mechanism 3 includes a transport housing 301 mounted on a bracket directly below the stamping area of ​​the stamping machine 1. A servo motor 303 is bolted to the left side of the outer wall of the transport housing 301. The output end of the servo motor 303 passes through the outer wall of the transport housing 301 and is fixedly connected to a sprocket 304 via a key connection. A chain 305 is meshed with the outer wall of the sprocket 304. A sprocket 306 is meshed with the other end of the inner wall of the chain 305. A conveyor belt 308 is fixedly connected to the outer wall of the chain 305 via vulcanization or bonding. A baffle 307 perpendicular to the surface of the conveyor belt 308 is fixedly connected to the outer wall of the conveyor belt 308 via hot-melt connection. The baffle 307 is used to prevent waste from slipping during the conveying process. The servo motor 303 drives the sprocket 304 to rotate, thereby driving the chain 305 and the conveyor belt 308 to rotate in a cycle, transporting the waste out from below the stamping area.

[0037] In a preferred embodiment, in order to achieve a smooth transition of waste material from the stamping table to the collection mechanism 3, a transport trough 302 is provided on the top wall of the transport housing 301. The transport trough 302 is located on both sides of the stamping area of ​​the stamping machine 1. The transport trough 302 vertically penetrates the top wall of the transport housing 301 and communicates with the interior of the transport housing 301. The transport trough 302 is located directly above the conveyor belt 308, so that the waste material generated by stamping can directly pass through the transport trough 302 and fall onto the surface of the conveyor belt 308.

[0038] In another preferred embodiment, in order to improve the stability of the conveyor belt 308 and prevent deviation, a connecting rod 309 is welded and fixedly connected to the right side of the outer wall of both sprocket 1 304 and sprocket 2 306. The connecting rod 309 is rotatably connected to the inner wall of the transport housing 301 through a bearing, and another set of sprocket 1 304 and sprocket 2 306 is fixedly connected to the other end of the connecting rod 309 through a key. Two sets of chains 305 are provided inside the transport housing 301. The two sets of chains 305 are arranged parallel to each other. The conveyor belt 308 is fixedly connected between the two sets of chains 305 and extends along the length direction of the transport housing 301.

[0039] As another preferred embodiment, in order to ensure effective gripping of waste materials of different shapes, multiple sets of baffles 307 are arranged in an array at equal intervals along the length of the conveyor belt 308. The surface of the baffles 307 is perpendicular to the outer surface of the conveyor belt 308, and the width of the baffles 307 is adapted to the width of the conveyor belt 308. The thrust generated by the baffles 307 when the conveyor belt 308 rotates is used to scrape the waste material to the outlet.

[0040] As another preferred embodiment, in order to facilitate the cleaning of the collected waste, the collection trough 4 is movably placed below the bottom wall of the transport housing 301. The opening of the collection trough 4 is located directly below the output end of the conveyor belt 308, and the size of the collection trough 4 is designed to be larger than the size of the transport trough 302 to ensure that the falling waste is completely caught. Rollers can be added to the bottom of the collection trough 4 as needed to facilitate movement.

[0041] Working principle: When it is necessary to fix the stamped sheet, the hydraulic push rod 204 is activated. The hydraulic push rod 204 drives the slider 1 203 to slide longitudinally on the slide rail 1 202. Since the slider 1 203 is hinged to the rotating plate 206 through the fixed rod 207, and the other end of the rotating plate 206 is connected to the slider 2 208, the longitudinal movement of the slider 1 203 forces the slider 2 208 to slide laterally on the slide rail 209 through the transmission of the rotating plate 206. This causes the clamping plate 210 fixed on the slider 2 208 to move inward to clamp the sheet, or move outward to release the sheet. The linkage transmission structure converts the unidirectional linear drive into a vertical clamping action, effectively ensuring the positional stability of the sheet during the stamping process.

[0042] When the stamping machine 1 produces scrap during the stamping operation, the scrap falls through the transport trough 302 onto the conveyor belt 308 inside the transport housing 301. At this time, the servo motor 303 is started, and the servo motor 303 drives the sprocket 304 to rotate, which in turn drives the chain 305 and the conveyor belt 308 connected to the chain 305 to rotate synchronously. The baffle 307 on the surface of the conveyor belt 308 moves accordingly and scrapes the fallen scrap towards the end of the conveyor belt 308. Finally, the scrap falls from the end of the conveyor belt 308 and enters the collection trough 4 placed below. Through the above-mentioned automated collection process, the waste is centrally processed and the working environment is kept clean.
