Description

Technical Field

[0001] This invention relates to the field of progressive die technology, specifically to a progressive die for an automotive support bracket. Background Technology

[0002] As a key connecting component of automobiles, automotive support brackets require high precision and efficiency in their production and processing. Continuous die technology can complete multiple stamping processes such as punching, bending, blanking, and forming on a single die, enabling continuous step-by-step stamping of the material strip. This significantly improves the production efficiency of parts and has become the core die equipment for the large-scale stamping production of automotive support brackets, which is widely used in the field of automotive parts processing.

[0003] However, in actual stamping production, existing progressive dies for automotive support brackets have the following drawbacks: the high-speed continuous stamping characteristics of progressive dies cause the waste generated from punching and blanking to accumulate continuously. The waste discharge structure of traditional dies is simple in design, resulting in low discharge efficiency and untimely discharge, which easily leads to blockage of waste in the collection groove and discharge channel inside the die. Scrap blockage not only interferes with the normal feeding of the strip and the die closing and stamping, leading to a decrease in stamping accuracy and a lower product qualification rate, but also forces the production line to stop for cleaning. Frequent shutdowns not only interrupt the continuous production rhythm and significantly reduce the overall stamping production efficiency, but also increase the workload and operating costs of manual cleaning, seriously affecting the large-scale production process of automotive support brackets. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous mold for an automotive support bracket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A continuous mold for an automotive support bracket includes: The frame has a lower mold base fixedly connected to the upper surface of the base plate, and a lower mold is detachably installed on the lower mold base. A hydraulic cylinder is fixedly connected to the upper surface of the top plate of the frame. The output end of the hydraulic cylinder passes through the top plate of the frame and is fixedly connected to the lifting plate. An upper mold base is fixedly connected to the lower surface of the lifting plate, and an upper mold adapted to the lower mold is detachably installed below the upper mold base. The bottom of the lower die is provided with multiple waste collection grooves to collect waste generated during the stamping and forming of the automobile support bracket. The rear end face of the lower mold is provided with a waste rapid discharge component for rapidly discharging waste from the waste collection trough; the upper end face of the base plate of the frame is provided with a collection box in front of the lower mold base for collecting waste discharged by the waste rapid discharge component. The rear end face of the lower mold is also provided with an air blowing component, which is used to blow out the waste debris remaining in the waste collection tank to ensure that the inside of the waste collection tank is clean.

[0006] Preferably, the waste rapid discharge assembly includes a mounting plate and a drive motor. The mounting plate is fixedly welded to the rear end face of the lower mold. Three upright plates arranged in a straight line are fixedly welded to the mounting plate. A sliding groove is opened horizontally on the upright plate, and a slider is slidably fitted in the sliding groove. The drive motor is fixedly connected to the outer wall of the middle upright plate by bolts. The output end of the drive motor passes through the upright plate and is fixedly connected to the rotating wheel. A connecting rod is hinged between the eccentric position of the rotating wheel and the slider. The sliders of adjacent upright plates are fixedly connected by a drive rod.

[0007] Preferably, the waste rapid discharge assembly further includes a receiving plate, which is inclinedly disposed in the waste collection trough. A hinge rod is fixedly connected to the rear end of the receiving plate. The hinge rod and the drive shaft are hinged together by a connecting plate. Through the transmission of the rotating wheel, connecting rod and slider, the rotational motion of the drive motor is converted into the reciprocating sliding of the slider in the slide groove, thereby driving the inclined receiving plate to perform reciprocating oscillating motion. By utilizing the dual effect of the inclined structure and reciprocating oscillation, the waste on the receiving plate is quickly slid out and discharged from the waste collection trough.

[0008] Preferably, a hinge seat I is fixedly connected to the lower end face of the receiving plate, and a hinge seat II is fixedly connected to the corresponding position at the bottom of the waste collection trough. The hinge seat I and the hinge seat II are hinged together to provide rotational support and movement limit for the reciprocating oscillation of the receiving plate, ensuring the stability of the receiving plate's movement trajectory.

[0009] Preferably, the air blowing assembly includes a connector and a flat nozzle. The connector is fixedly connected to the rear end face of the lower mold and is connected to an external air source. The flat nozzle is fixedly connected to the inner rear end face of the waste collection trough, and the installation position of the flat nozzle is lower than the receiving plate. An inclined waste receiving plate is fixedly connected to the bottom of the front end face of the lower mold to guide the waste discharged from the waste collection trough to the collection box and prevent the waste from scattering.

[0010] Preferably, the bottom sides of the lower mold are fixedly connected with fixing ear plates, and the upper end face of the lower mold base is provided with an installation groove whose shape is adapted to the bottom of the lower mold and the fixing ear plates for positioning and installing the lower mold. The upper end face of the lower mold base is provided with an avoidance groove in front of the installation groove to avoid the waste material receiving plate at the bottom of the lower mold and ensure the installation fit of the lower mold.

[0011] Preferably, the fixing ear plate is fixedly connected to the mounting groove of the lower mold base by fixing bolts, so as to realize the detachable fixing of the lower mold and the lower mold base, which facilitates the replacement and maintenance of the lower mold.

[0012] Preferably, the lower die base is made of high-strength alloy structural steel, which can withstand high pressure impact and repeated loads during the stamping process. A guide rod is fixedly connected to the lower end face of the lifting plate of the frame, and a guide cylinder is fixedly connected to the upper end face of the base plate of the frame at the position corresponding to the guide rod. The guide rod and the guide cylinder slide together to provide guidance and limit for the up and down movement of the lifting plate, ensuring the mold closing accuracy of the upper and lower dies.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting up a waste rapid discharge component, converts the rotational motion of the motor into the reciprocating oscillation of the receiving plate. Combined with the inclined structure of the receiving plate, it utilizes the dual effects of gravity and inertia to achieve rapid discharge of large pieces of waste, thereby improving waste discharge efficiency and preventing waste accumulation from clogging the discharge channel.

[0014] This invention, by setting up an air blowing component and a waste rapid discharge component for use together, uses high-pressure air blowing to clean up fine waste debris and dust that cannot be carried out by the receiving plate, thoroughly cleaning the inside of the waste collection tank, avoiding blockage caused by the adhesion and accumulation of fine waste, and further ensuring continuous operation of the equipment.

[0015] This invention, by setting up a waste collection tank corresponding to the stamping station, can collect various types of waste generated during the stamping process, preventing waste from scattering inside the equipment and causing accumulation, thus reducing equipment blockage problems from the source.

[0018] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please see Figures 1 to 6 The present invention provides a technical solution: A progressive die for automotive support brackets is used for stamping and forming of automotive support brackets. It also integrates automatic waste collection, rapid discharge and residual chip removal functions, effectively solving the problems of waste accumulation and cumbersome chip removal in traditional progressive die stamping processes, and improving stamping efficiency and equipment operation stability.

[0020] The frame 1 is made of welded steel, with a solid overall structure and strong compressive strength, which can withstand the high pressure impact and vibration during the stamping process.

[0021] The lower die base 4 is fixedly connected to the upper surface of the base plate of the frame 1 by a combination of bolts and welding. The lower die base 4 is preferably made of high-strength alloy structural steel through forging and tempering, which has excellent compressive strength, wear resistance and fatigue resistance, and can withstand high pressure impact and repeated loads during the stamping process for a long time, ensuring the stability and non-deformation of the die base structure. The lower die 6 is detachably installed on the lower die base 4. The upper surface of the top plate of the frame 1 is fixedly connected to the hydraulic cylinder 2 by a flange. The hydraulic cylinder 2 provides power output for the stamping operation. Its output end passes vertically downward through the top plate of the frame 1 and is coaxially fixedly connected to the lifting plate 104. The lower end of the lifting plate 104 is fixedly connected to the upper die base 3 by bolts. The upper die 301, which is compatible with the lower die 6, is detachably installed below the upper die base 3 by bolts. The hydraulic cylinder 2 drives the lifting plate 104 to move the upper die base 3 and the upper die 301 up and down in a reciprocating motion, which works with the lower die 6 to complete the continuous stamping forming operation of the automobile support bracket.

[0022] In this embodiment, the bottom plate of the frame 1 is also provided with an inclined discharge plate 7 by means of a bracket. The discharge plate 7 is correspondingly set at the side discharge station of the lower die 6. Its high end is connected to the stamping and forming discharge port of the lower die 6, and its low end extends outward and downward at an inclination. The finished car support bracket after stamping can slide directly from the discharge port of the lower die 6 onto the discharge plate 7. With the help of the inclined structure of the discharge plate 7, the finished product is guided and transported in an orderly manner, and the finished product and waste are separated and collected, avoiding the mixing of finished product and stamping waste, and improving the continuity and efficiency of the overall stamping production.

[0023] It should be noted that progressive dies are a type of die used in stamping production to perform continuous step-by-step stamping of material strips. They can complete multiple stamping processes such as punching, bending, blanking, and forming on a single die, significantly improving the stamping production efficiency of parts. They are a commonly used die type in the large-scale stamping of automotive parts. Progressive dies are usually used in conjunction with industry-standard material conveying systems. The continuous stamping operation is achieved through the step-by-step feeding of the material strip system. The dimensions of the lower die 6 and the upper die 301, as well as the type, number, and arrangement of stamping stations, can be flexibly selected and designed according to the specific production process requirements of automotive support brackets. Their compatibility with the material strip only needs to conform to the specifications and dimensions of common material strips in the industry. The conventional stamping feeding structure and operating principle of progressive dies that cooperate with the upper and lower dies are existing, mature, and conventional technologies, which do not need to be elaborated on here.

[0024] The bottom of the lower die 6 has multiple waste collection slots 602 corresponding to the stamping stations. The size of the waste collection slots 602 is adapted to the shape of the stamping waste, which can accurately receive various wastes generated during the stamping and blanking process of automotive support brackets, avoiding the accumulation of waste inside the equipment and causing blockages. To address the waste discharge problem in the waste collection slots 602, a waste rapid discharge component 8 is provided on the rear end face of the lower die 6, which is used to quickly and automatically discharge the waste accumulated in the waste collection slots 602. A collection box 5 is placed on the upper surface of the base plate of the frame 1 in front of the lower die base 4. The collection box 5 is a slot-shaped structure with an open top, which is used to receive all the waste discharged by the waste rapid discharge component 8, realizing centralized collection and subsequent unified processing of waste.

[0025] In this embodiment, the waste rapid discharge assembly 8 includes a mounting plate 801, a drive motor 806, a vertical plate 802, a slider 804, a rotating wheel 805, a connecting rod 807, a drive rod 808, a receiving plate 809, a hinge rod 811, a connecting plate 810, and a hinge seat assembly. The components work together to achieve automated vibration discharge of waste. The mounting plate 801 is fixedly welded to the rear end face of the lower mold 6 by full welding. Three upright plates 802 are fixedly welded to the mounting plate 801 at equal intervals in a straight line. The upright plates 802 are made of high-strength steel plates to ensure the stability of the structural support. Each upright plate 802 has a horizontally opened sliding groove 803. A slider 804 slides in the sliding groove 803. The mating surface between the slider 804 and the sliding groove 803 is polished to reduce sliding friction resistance. The drive motor 806 is fixedly connected to the outer wall of the middle upright plate 802 by a motor mounting seat and bolts. The output end of the drive motor 806 passes horizontally through the upright plate 802 and is fixedly connected to the rotating wheel 805 on the same axis. A connecting rod 807 is hinged between the eccentric position of the rotating wheel 805 and the slider 804 of the middle upright plate 802. The sliders 804 of adjacent upright plates 802 are fixedly connected by a drive rod 808, so that the sliders 804 on the three upright plates 802 can slide back and forth synchronously.

[0026] The receiving plate 809 is inclinedly set in the waste collection trough 602. The inclination angle of the receiving plate 809 is adapted to the waste sliding out requirements. Its surface is smoothed to prevent waste from adhering. The rear end of the receiving plate 809 is vertically fixedly connected to a hinge rod 811. The hinge rod 811 and the drive rod 808 are hinged through a connecting plate 810. Through the transmission cooperation of the rotating wheel 805, the connecting rod 807 and the slider 804, the rotational motion of the drive motor 806 is converted into the back-and-forth sliding motion of the slider 804 in the slide groove 803. The slider 804 drives the drive rod 808 to move synchronously. Then, through the connecting plate 810 and the hinge rod 811, the inclined receiving plate 809 is driven to perform a back-and-forth oscillating motion. Utilizing the dual effect of the inclined structure and the back-and-forth oscillation of the receiving plate 809, the stamping waste received on the receiving plate 809 slides forward quickly under the action of inertia and gravity and is smoothly discharged from the waste collection trough 602.

[0027] An inclined waste receiving plate 601 is fixedly connected to the bottom of the front end face of the lower mold 6. The upper end of the waste receiving plate 601 is connected to the front opening of the waste collection trough 602, and the lower end is inclined toward the collection box 5. This is used to smoothly guide the waste discharged from the waste collection trough 602 to the collection box 5, prevent the waste from scattering to the outside of the equipment during the discharge process, and ensure the cleanliness and integrity of the waste collection.

[0028] It should be noted that, in order to ensure the stability of the oscillating motion of the receiving plate 809, a hinge seat I 812 is fixedly connected to the lower end face of the receiving plate 809, and a hinge seat II 813 is fixedly connected to the corresponding position at the bottom of the waste collection trough 602. The hinge seat I 812 and the hinge seat II 813 are hinged together. This hinge structure provides stable rotational support and motion trajectory limit for the reciprocating oscillating motion of the receiving plate 809, preventing the receiving plate 809 from deviating or shaking during the motion, and ensuring the smoothness of the waste discharge action.

[0029] To enable rapid disassembly and replacement of the lower die 6 and adapt to the stamping processing of automotive support brackets of different specifications, the lower die 6 has integrally formed or welded fixed ear plates 603 on both sides of its bottom. The upper surface of the lower die base 4 has an installation groove 401 whose shape matches the bottom of the lower die 6 and the fixed ear plates 603. The installation groove 401 provides precise positioning for the installation of the lower die 6, ensuring coaxiality and fit after installation. An avoidance groove 402 is also provided on the upper surface of the lower die base 4 in front of the installation groove 401 to avoid the scrap receiving plate 601 at the bottom of the lower die 6, preventing interference between the scrap receiving plate 601 and the lower die base 4, and ensuring smooth installation and fixation of the lower die 6. The fixed ear plates 603 are fixedly connected to the installation groove 401 of the lower die base 4 by fixing bolts 605. This bolt connection allows for detachable fixing of the lower die 6 and the lower die base 4, simplifying disassembly and facilitating replacement, maintenance, and repair of the lower die 6.

[0030] The lower end face of the lifting plate 104 of the frame 1 is symmetrically connected with guide rods 102. The upper end face of the base plate of the frame 1 is fixedly connected with guide cylinders 103 at the corresponding positions of the guide rods 102. The guide rods 102 and guide cylinders 103 are slidably engaged, and wear-resistant bushings are provided on the mating surfaces. The guiding structure of the guide rods 102 and guide cylinders 103 provides stable guidance and limit for the up and down movement of the lifting plate 104, effectively preventing the lifting plate 104 from swaying or tilting during the movement, ensuring the alignment accuracy of the upper die 301 and the lower die 6 during die closing and stamping, and improving the processing quality of the stamped products.

[0031] Example 2: Please see Figures 7 to 8 The present invention also provides a technical solution that is basically the same as that in Embodiment 1, except that: In this embodiment, the waste discharge component 8 is used to prevent waste from accumulating in the collection tank and blocking the discharge channel, thereby preventing the equipment from shutting down due to waste jamming. However, in addition to the large pieces of waste that can be discharged by the vibration of the receiving plate 809, a large amount of fine waste and dust are also generated during the stamping process. These fine wastes are easy to adhere to the inner wall of the waste collection tank 602 and the gaps of the receiving plate 809. They are difficult to be completely removed by the reciprocating vibration of the receiving plate 809, which can easily cause the tank to be blocked by accumulated debris.

[0032] The rear end face of the lower mold 6 is also equipped with an air blowing component, which is used to blow out the fine waste and dust remaining in the waste collection tank 602, so as to ensure the cleanliness of the inside of the waste collection tank 602 and avoid the accumulation of waste to affect subsequent stamping operations and waste discharge.

[0033] In this embodiment, the air blowing assembly includes a connector 9 and a flat nozzle 901. The connector 9 is preferably a pneumatic quick connector, which is fixedly connected to the rear end face of the lower mold 6. One end of the connector 9 is connected to an external air source 10, and the other end is connected to the flat nozzle 901. The flat nozzle 901 is fixedly connected to the inner rear end face of the waste collection tank 602, and the installation position of the flat nozzle 901 is lower than the receiving plate 809. Its air outlet direction is towards the front opening of the waste collection tank 602. The high-pressure airflow is blown out in a flat shape through the flat nozzle 901, which can fully cover the bottom of the waste collection tank 602, efficiently blow away the fine waste residue in the tank, and avoid the accumulation of waste residue.

[0034] It should be noted that the drive motor 806 in this device is preferably a Jingyan MG80A075Y38HT5 three-phase 380V servo geared motor with a power of 0.75kW and a reduction ratio of 1:5. Its output torque and speed are adapted to the working conditions of waste material vibration discharge, and it operates stably and adjusts precisely. The hydraulic cylinder 2 is preferably a Hander hydraulic HSG100 / 55-300 heavy-duty single-rod double-acting hydraulic cylinder with a cylinder diameter of 100mm and a stroke of 300mm. It can withstand the high pressure impact under stamping conditions and meet the stamping power requirements of automotive support brackets. The PLC controller is preferably a Mitsubishi FX3U-32MT / ES-A industrial programmable logic controller with sufficient I / O points, which can stably realize the linkage control of multiple components. The MG80A075Y38HT5 servo geared motor, HSG100 / 55-300 hydraulic cylinder, and external air source 10 are all electrically connected to the Mitsubishi FX3U-32MT / ES-A PLC controller. After receiving the stamping start and stop signal, the PLC synchronously controls the up and down stamping and lifting of the hydraulic cylinder 2, the reciprocating oscillation of the drive motor 806, and the intermittent chip removal blowing of the air blowing component, so as to realize the automated and coordinated operation of stamping, waste discharge, and chip removal. The circuit wiring, signal transmission, and on-site installation and fixing methods between each component and the PLC are all conventional and mature technologies in the field of industrial control, and there is no need to elaborate on them here.

[0035] In use, this invention first assembles the upper mold 301 and lower mold 6 precisely according to the production process requirements of the automotive support bracket. The material conveying system is then aligned and adapted with the continuous die. The collection box 5 is placed below the waste receiving plate 601 in front of the lower mold base 4. The pneumatic quick connector 9 is connected to the external air source 10. After starting the equipment, the PLC controller synchronously triggers the hydraulic cylinder 2, causing the upper mold 301 to reciprocate up and down with the lifting plate 104. This, in conjunction with the lower mold 6, continuously stamps and forms the material strip. The stamped finished product slides from the lower mold 6's outlet onto the inclined discharge plate 7 for orderly conveying. Large pieces of waste generated during stamping fall into the waste collection trough 602. On the receiving plate 809, the drive motor 806 drives the rotating wheel 805 to rotate and converts the rotational motion into the reciprocating oscillation of the receiving plate 809 through the connecting rod 807 and the slider 804. This causes large pieces of waste to slide into the collection box 5 through the waste receiving plate 601 under the action of gravity and inertia. At the same time, the flat nozzle 901 of the air blowing component continuously blows out high-pressure airflow, blowing the fine waste and dust that the receiving plate 809 cannot carry out in the waste collection trough 602 into the collection box 5. This realizes the automated and coordinated operation of stamping, finished product discharge, large waste vibration discharge, and fine waste blowing and cleaning. The entire process does not require manual intervention and completes the continuous and efficient stamping processing of the automotive support bracket.

[0036] All other parts of this invention not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
