Description

Technical Field

[0001] This invention belongs to the technical field of automotive parts processing equipment, and in particular relates to an automotive parts stamping and forming device. Background Technology

[0002] Stamping is one of the most widely used processing technologies in the manufacturing of automotive parts. It offers high processing efficiency and good forming results, meeting the demands of large-scale automotive parts production. However, existing automotive parts stamping equipment still suffers from numerous technical shortcomings in practical use, making it difficult to adapt to modern processing requirements. 1. The upper die's punch module is mostly an integrated fixed structure, which cannot flexibly adjust the position and height according to the stamping requirements of automotive parts of different specifications and sizes. The device has poor adaptability, and the entire upper die assembly needs to be replaced when processing parts of different specifications. This not only increases the procurement and replacement cost of the die, but also significantly reduces the processing efficiency. 2. The bottom module of the lower die is fixed in position, making it difficult to adjust precisely according to the stamping depth requirements of the parts. This makes it difficult to control the stamping accuracy and can easily lead to problems such as stamping too deep or too shallow, affecting the forming quality of automotive parts. 3. After stamping, most of the parts are unloaded manually, which is inefficient. In addition, the close contact between the stamping dies and the workers poses a safety hazard of being pinched or bumped by the dies, which does not meet the requirements of safe production. 4. The stamping guide structure of the device is poorly designed and lacks stability. During the stamping process, the moving plate that drives the cam module is prone to deviation and shaking, which directly affects the stamping accuracy of the parts and reduces the yield.

[0003] To address the shortcomings of the existing technology, this invention designs a stamping forming device for automotive parts. By optimizing the design of the mold structure, guiding structure, and unloading structure, the above-mentioned technical problems are solved, and the adaptability, stamping accuracy, and processing safety of the device are improved. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping and forming apparatus for automotive parts, thereby solving the existing problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a stamping forming device for automotive parts, comprising a base plate, which is a rectangular thick plate structure made of stainless steel with a thickness of 8-12cm to ensure the overall load-bearing capacity of the device; support rods are fixed to the four corners of the upper surface edge of the base plate by welding, the support rods are high-strength alloy cylindrical rods, the four support rods are distributed in a rectangular array, and the upper ends are connected to a bearing plate, which is a rectangular steel plate matching the base plate with a thickness of 6-8cm, used to support the lower die assembly and the column.

[0006] Each of the four corners of the upper surface of the support plate is fixed with a column. The column is an alloy rod with a chrome-plated anti-rust treatment. A mounting plate is fixed to the upper end of the column. A hydraulic telescopic rod is fixed to the middle of the upper surface of the mounting plate by bolts. The hydraulic telescopic rod is a double-acting hydraulic push rod with a rated thrust of 5-20T, which is suitable for the stamping requirements of metal parts of different thicknesses. The output end of the hydraulic telescopic rod extends to the lower part through a through hole in the mounting plate and is fixedly connected to the moving plate by a flange. Guide holes are opened at each of the four corners of the moving plate. Guide rings matching the column are fixed in the guide holes by interference fit. The guide rings are made of polytetrafluoroethylene, which has self-lubricating and wear-resistant properties and reduces sliding friction with the column. The upper mold assembly is fixed to the middle of the lower surface of the moving plate by bolts.

[0007] The upper die assembly includes an adjustment seat fixed to the center of the lower surface of the movable plate by bolts, and a convex module movably installed in the adjustment seat.

Its two opposite surfaces are welded with a slide rod that matches the straight slot hole. One end of the slide rod has an internal thread hole. The other end of the internal thread hole is fixedly connected to a limit toothed plate through an adjustment screw. The end of the adjustment screw is equipped with an anti-slip handwheel for easy manual adjustment.

[0008] The shape and size of the limiting tooth plate are adapted to the tooth plate, and the limiting tooth plate and the tooth plate are engaged to achieve the limiting and fixing of the convex module after adjustment; the shape and size of the convex module are adapted to the mounting cavity of the adjusting seat, and the convex module and the adjusting seat cooperate with each other; the shape and size of the straight slot hole are adapted to the slide rod, and the straight slot hole and the slide rod are engaged to ensure the smoothness of the convex module lifting and lowering adjustment.

[0009] A mounting groove is provided in the middle of the support plate. A lower die assembly is fixed in the mounting groove by bolts. The lower die assembly includes a die sleeve that matches the convex module and is fixed in the middle of the support plate by bolts, and a bottom module that is movably set in the die sleeve. The shape and size of the die sleeve are adapted to the bottom module. There is a clearance fit between the die sleeve and the bottom module with a clearance value of 0.05-0.1mm, which ensures the smooth lifting of the bottom module and prevents the blank from overflowing during the stamping process. The concave die formed by the die sleeve and the bottom module is adapted to the convex module to ensure the consistency of stamping.

[0010] A support plate is welded to the lower surface of the base module. Adjustment screw holes are provided on both sides of the upper surface of the support plate. An adjustment screw is connected to the internal thread of the adjustment screw hole. The adjustment screw is a precision ball screw with a transmission accuracy of 0.01mm / revolution, ensuring the accuracy of the lifting adjustment of the base module. The upper end of the adjustment screw is rotatably connected to the lower surface of the support plate through a bearing, and the lower end of the adjustment screw is rotatably connected to the upper surface of the base plate through a bearing. A transmission wheel is fixed to the lower end of the peripheral side of the adjustment screw through a flat key. A drive wheel meshes between the two transmission wheels. Both the transmission wheel and the drive wheel are precision spur gears with hardened tooth surfaces to improve wear resistance.

[0011] The shape and size of the transmission wheel are adapted to the drive wheel, and there is a clearance fit between the transmission wheel and the drive wheel; a rotating shaft is fixed in the middle of the drive wheel by a flat key, and the lower end of the rotating shaft extends through the through hole opened in the base plate to the bottom, and is fixedly connected to the output end of the servo motor A by a coupling. The servo motor A is a stepper servo motor with adjustable speed and a self-locking function to prevent the bottom module from being displaced due to the stamping pressure.

[0012] A bracket is bolted to the rear of the base plate. The bracket is a welded metal frame structure with good structural strength. An electric telescopic rod is bolted to one side of the bracket. The electric telescopic rod is an electric push rod. A push plate is bolted to the output end of the electric telescopic rod. The push plate is an elastic plate made of polyurethane. A rubber pad is fixed to its contact surface by adhesive. The rubber pad is made of wear-resistant nitrile rubber with a thickness of 3-5mm to prevent the push plate from making hard contact with the parts and causing scratches.

[0013] A material ejection assembly is bolted to the base plate located in front of the lower mold assembly. The material ejection assembly includes a transmission frame bolted to the base plate. The transmission frame is a metal frame structure, and its height is slightly lower than the upper surface of the mold sleeve to ensure smooth pushing of parts. Rollers are connected to the upper surface of the transmission frame by bearings. The rollers are polyurethane-coated rollers to prevent scratching of the surface of the parts. The shaft of the roller near the lower mold assembly extends through the transmission frame to the outside and is fixedly connected to the output end of servo motor B through a coupling. Servo motor B is a speed-regulating motor, and its speed is matched with the pushing speed of the electric telescopic rod.

[0014] The transmission wheel and drive wheel are covered with a protective shell. The protective shell is a closed shell made of stainless steel and is fixed to the upper surface of the base plate with bolts. This can effectively prevent metal debris and oil from entering the transmission structure. The upper surface of the protective shell has clearance holes on both sides that match the adjusting screw. The upper end of the rotating shaft is rotatably connected to the inner wall of the protective shell through a bearing, which improves the rotational stability of the rotating shaft.

[0015] Support legs are fixed to the four corners of the bottom surface of the base plate with bolts; rubber anti-slip pads are fixed to the lower end of the support legs by adhesive bonding. The rubber anti-slip pads are made of butyl rubber with anti-slip texture, which not only has good anti-slip performance, but also effectively absorbs the vibration generated during the stamping process, reducing the vibration and noise of the device.

[0016] A controller is bolted to one side of the upper surface of the support plate. The controller is a PLC programmable controller with a touch screen and an emergency stop button, which can realize parameter setting, process control and emergency stop. The controller is electrically connected to the hydraulic telescopic rod, servo motor A, servo motor B and electric telescopic rod to control the operation of the entire device and realize the automated linkage control of processes such as stamping, mold adjustment and unloading.

[0017] The shape and size of the column are adapted to the guide ring. The column and the guide ring slide together to provide precise guidance for the up and down movement of the moving plate and prevent the moving plate from deviating or shaking.

[0018] The present invention has the following beneficial effects: The upper die assembly of this invention adopts an adjustable structure design. The convex module slides with the straight slot hole of the adjusting seat through the sliding rod, which can realize the flexible adjustment of the height and position of the convex module. With the locking fit of the limiting tooth plate, the adjusted convex module can be stably limited. It can adapt to the stamping requirements of different specifications of automotive parts without replacing the entire upper die assembly, effectively reducing the cost of mold procurement and replacement and improving processing efficiency.

[0019] The lower die assembly of this invention is equipped with a liftable bottom module. The servo motor A drives the drive wheel and transmission wheel to rotate, which in turn drives the adjusting screw to rotate, so as to achieve precise lifting and lowering of the support plate and the bottom module. The position of the bottom module can be flexibly adjusted according to the stamping depth requirements of the parts, effectively improving the stamping accuracy and ensuring the forming quality of the parts.

[0020] This invention features an automatic unloading structure consisting of an electric telescopic rod, a push plate, and an unloading assembly. After stamping, the electric telescopic rod pushes the push plate to place the stamped parts onto the rollers of the unloading assembly. The servo motor B drives the rollers to rotate, achieving automatic conveying and unloading of the parts. This replaces manual unloading operations, not only improving unloading efficiency but also avoiding safety hazards caused by manual contact with the mold, thus meeting safety production requirements.

[0021] The present invention provides a guide ring matching the column in the guide hole of the moving plate. The column and the guide ring slide together to provide precise guidance for the up and down movement of the moving plate, effectively preventing the moving plate from deviating or shaking during the stamping process, ensuring the precise alignment of the convex module and the lower die assembly, further improving the stamping forming accuracy of the parts and increasing the processing yield.

[0022] The transmission wheel and drive wheel of this invention are covered with protective shells, which can effectively prevent debris and foreign matter from entering the transmission structure during processing, ensuring the stability and smoothness of transmission and extending the service life of the device; the lower surface of the base plate is provided with support legs with rubber anti-slip pads, which can effectively improve the stability of the device and prevent the device from slipping during stamping; the rubber pads on the push plate can avoid hard contact between the push plate and the parts, preventing the parts from being scratched or bumped, and ensuring the appearance quality of the parts.

[0023] This invention enables centralized control of the hydraulic telescopic rod, servo motor A, servo motor B, and electric telescopic rod through a controller, which can realize the automated operation of processes such as stamping, mold adjustment, and unloading, greatly improving the overall processing efficiency and reducing the intensity of manual operation.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Example 1 Please see Figures 1-7 As shown, this invention is a stamping forming device for automotive parts. Before actual use, it needs to be precisely adjusted according to the material, specifications, stamping depth, and other requirements of the automotive parts to be processed. The specific adjustment steps are as follows: Step S1, Device Leveling Adjustment: Place the device on a flat production site, screw on the support legs 7 on the lower surface of the base plate 1 to adjust the height of the four support legs 7 so that the base plate 1 and the bearing plate 102 of the device are level. After adjustment, ensure that the rubber anti-slip pads 701 at the lower end of the support legs 7 are in close contact with the ground to prevent the device from slipping.

[0032] Step S2, Adjustment of upper mold component 2: 1. The operator loosens the adjusting screw 208 by using the anti-slip handwheel to separate the limiting toothed plate 209 from the toothed plate 205, thereby releasing the limiting of the convex module 202; 2. According to the specifications of the parts to be processed, push the convex module 202 to slide up and down in the mounting cavity of the adjusting seat 201, and the slide rod 206 moves synchronously along the straight slot hole 204 to adjust the height and position of the convex module 202 until the convex module 202 matches the stamping requirements of the parts to be processed. 3. Tighten the adjusting screw 208 to ensure that the limiting toothed plate 209 and the toothed plate 205 are tightly engaged, thereby achieving a stable limiting of the convex module 202 and preventing displacement of the convex module 202 during the stamping process.

[0033] Step S3, Adjustment of lower mold assembly 3: 1. Input the stamping depth parameters of the parts to be processed and set the number of rotations of the servo motor A309 through the controller touch screen on the support plate 102; 2. Start the controller's debugging mode. Servo motor A309 drives the rotating shaft 308 and drive wheel 307 to rotate. Drive wheel 307 meshes with two transmission wheels 306, driving the adjusting screw 305 to rotate. 3. The support plate 303 is threadedly connected to the adjusting screw 305 through the adjusting screw hole 304. It rises and falls with the rotation of the adjusting screw 305, driving the bottom module 302 to move precisely within the mold sleeve 301 until the bottom module 302 reaches the preset stamping depth position. 4. The servo motor A309 is self-locking, fixing the position of the bottom module 302 and completing the adjustment of the lower mold assembly 3.

[0034] Step S4, setting unloading structure parameters: Set the extension speed and stroke of the electric telescopic rod 401 and the rotation speed of the servo motor B603 through the controller touch screen to match the unloading speed with the stamping rhythm and ensure smooth pushing and conveying of parts.

[0035] Step S5, Stamping pressure adjustment: Adjust the hydraulic system pressure of the hydraulic telescopic rod 105 according to the thickness of the material of the parts to be processed, such as cold-rolled steel plate, aluminum alloy plate, etc., and set an appropriate stamping thrust to avoid deformation of parts due to excessive pressure and substandard forming due to insufficient pressure.

[0036] Example 2 This embodiment describes the actual processing operation steps of a stamping forming device for automotive parts. After the device is debugged, stamping forming of automotive parts can be performed. The specific operation steps are as follows: Feeding: The metal blank to be processed is placed stably in the cavity formed by the mold sleeve 301 and the bottom module 302 of the lower mold assembly 3 to ensure that the blank and the cavity are accurately aligned. It can be used with manual feeding or automated feeding equipment to achieve continuous feeding.

[0037] Stamping: The stamping program is started by the controller. The output end of the hydraulic telescopic rod 105 extends downward, pushing the moving plate 106 to move downward along the column 103. The guide ring 108 slides along the column 103 to provide precise guidance for the moving plate 106. The moving plate 106 drives the convex module 202 of the upper die assembly 2 to move downward synchronously. The convex module 202 performs cold stamping on the blank in the die. After stamping is completed, the hydraulic telescopic rod 105 drives the moving plate 106 and the convex module 202 to return to the initial position.

[0038] Automatic unloading: After the convex module 202 is reset, the controller automatically starts the unloading program. The support plate 303 is threadedly connected to the adjusting screw 305 through the adjusting screw hole 304. The adjustment screw 305 rotates to achieve lifting and lowering, thereby ejecting the stamped parts through the bottom module 302. Then, the output end of the electric telescopic rod 401 extends forward, pushing the push plate 402 to move towards the discharge assembly 6. The push plate 402 smoothly pushes the stamped parts onto the roller 602 of the discharge assembly 6. At the same time, the servo motor B603 starts, driving the roller 602 to rotate, conveying the parts along the transmission frame 601 away from the lower die assembly 3, realizing automated unloading. After unloading is completed, the electric telescopic rod 401 drives the push plate 402 to reset to the initial position.

[0039] Continuous processing: After completing one stamping and unloading process, repeat the above steps of feeding, stamping, and automatic unloading to achieve continuous stamping processing of automotive parts; if it is necessary to change the processing specifications, simply readjust the parameters of the upper die assembly 2 and the lower die assembly 3 according to the device debugging steps, without having to replace the entire mold.

[0040] Routine maintenance and upkeep of the equipment To ensure the operational stability and service life of the equipment, regular daily maintenance and upkeep are required. Specific requirements are as follows: Guide structure maintenance: Apply high-temperature resistant lubricating oil to the column 103 and guide ring 108 once a week to maintain the smooth sliding of the guide structure. At the same time, clean the metal debris and oil stains on the surface of the column 103 to prevent wear on the guide ring 108.

[0041] Transmission structure maintenance: Open the protective shell 5 monthly, apply precision gear grease to the transmission wheel 306, drive wheel 307 and adjusting screw 305, clean the debris in the transmission clearance, check the meshing of the gears, and replace them in time if the tooth surface is severely worn.

[0042] Hydraulic system maintenance: The hydraulic system of the hydraulic telescopic rod 105 should be inspected quarterly, the hydraulic oil should be replenished, and the hydraulic lines should be checked for leaks. If leaks are found, the seals should be replaced in time.

[0043] Inspection of vulnerable parts: Check the wear of vulnerable parts such as guide ring 108, bearing, rubber pad 403, and roller 602 monthly. If wear, deformation, aging or other problems are found, replace the standardized parts in time.

[0044] Electrical system inspection: Check the electrical wiring connections of the controller, servo motor, and electric telescopic pole weekly to ensure that the wiring is not loose or short-circuited, and check the sensitivity of the emergency stop button to ensure the safe operation of the electrical system.

[0045] Overall cleaning: After processing, promptly clean the metal debris and oil stains from the surface of the device and inside the mold to keep the device and mold clean and prevent rust.
