Description

Technical Field

[0001] This application relates to the technical field of metal processing equipment, and particularly to an automatic production equipment for embossing. Background Art

[0002] In modern industrial production, metal sheet processing technology has been widely applied, especially in industries such as automobile manufacturing, household appliance production, and building decoration. As an important part of metal sheet forming, the embossing process forms a raised structure by stamping specific parts of the workpiece to meet the functional requirements of different products. In recent years, with the continuous change of market demand and the improvement of product design complexity, higher requirements have been put forward for the accuracy, efficiency, and adaptability of the embossing process. To meet this challenge, the industry has gradually developed towards automation and integration, striving to break through the limitations of traditional processes through technological innovation.

[0003] Currently, when solving the problem of embossing at the bent part of the workpiece, common practices in the industry include various means. First, traditional manual operation is still an option in certain scenarios, that is, workers manually complete steps such as positioning, clamping, and stamping with the help of simple tools; second, semi-automatic single-station punching presses are also widely used. This equipment is equipped with fixed die modules and can achieve a certain degree of mechanized operation, but manual participation is still required for loading and unloading; furthermore, some enterprises have adopted a multi-station cooperation mode, using manipulators or other transmission systems to sequentially feed the workpiece into each workstation to perform different processes such as pre-bending and precise shaping.

[0004] However, these existing methods still face a common technical bottleneck, that is, how to ensure good consistency and stability throughout the processing flow. Especially when dealing with long or other special-shaped components, due to the lack of effective synchronous control measures, uneven stress on both sides often occurs, which in turn leads to a series of adverse consequences such as asymmetric deformation or decreased surface quality. Summary of the Invention

[0005] To solve the above technical problems, this application provides an automatic production equipment for embossing.

[0006] The automatic production equipment for embossing provided by this application adopts the following technical solutions: An automatic production equipment for embossing, comprising: An automatic production line for automatically feeding workpieces to be processed, including a production line for conveying workpieces and a driving device for driving the workpieces to feed along the length direction of the production line to the processing position; The convex hull machine is arranged on one side of the automatic production line and is used to punch convex hulls at the bent parts of workpieces. The convex hull machine includes a frame, an upper die head inclined above the frame, a die base horizontally arranged in the middle of the frame, and a lower die head inclined below the frame; the die base is provided with a guiding hole that slidably cooperates with the lower die head; when the workpiece is fed to the machining position of the die base under the action of the driving device, the lower die head is exposed outside the guiding hole and cooperates with the upper die head to form the convex hull at the bent part of the workpiece.

[0007] By adopting the above technical solution, the automatic feeding of workpieces to be machined and the efficient punching of convex hulls are realized. The automatic production line can stably convey workpieces to the machining position, ensuring the continuity of the production process and improving work efficiency; the design of the convex hull machine enables the upper die head and the lower die head to form a convex hull structure at the bent part of the workpiece, ensuring the consistency of product quality.

[0008] Preferably, a convex die is arranged on the end face of the upper die head, a concave die is arranged on the end face of the lower die head, the upper die head is detachably connected to a first driving component inclined at the upper end of the frame, and the lower die head is detachably connected to a second driving component inclined at the lower end of the frame.

[0009] By adopting the above technical solution, the detachable connection of the upper die head and the lower die head to the first driving component and the second driving component respectively is realized, which is convenient for quickly replacing the corresponding dies or adjusting equipment parameters according to the needs of different workpieces; at the same time, the design of the convex die and the concave die makes the convex hull formed at the bent part of the workpiece more accurate, improving the machining accuracy and efficiency. This modular design improves the flexibility and adaptability of the equipment, reduces the maintenance cost, and ensures the stability and reliability of the production process.

[0010] Preferably, a step is arranged on one side wall of the die base facing the upper die head, and the guiding hole penetrates through the corner of the step; the two bent walls at the bent part of the workpiece are attached to the two step surfaces of the step.

[0011] By adopting the above technical solution, a step is arranged on one side wall of the die base facing the upper die head, so that the two bent walls at the bent part of the workpiece can be attached to the two step surfaces of the step, thereby realizing the precise positioning of the workpiece during the machining process. At the same time, the guiding hole penetrates through the corner of the step, ensuring that the lower die head can stably slide in the guiding hole and cooperate with the upper die head, further improving the quality and accuracy of convex hull forming.

[0012] Preferably, the included angle between the axis of the guiding hole and the horizontal plane of the step is greater than 15 degrees and less than 60 degrees.

[0013] By adopting the above technical solution, the optimized design of the angle between the axis of the guiding hole and the horizontal plane of the step is realized. Specifically, the effective setting of this angle range can ensure that the lower die head has an appropriate inclination angle when stamping the workpiece, thereby improving the stability of the stamping process and effectively avoiding the phenomenon of the workpiece shifting or jamming during the processing. At the same time, this design can also improve the quality and consistency of the convex hull forming, making the convex hull formed at the bending part of the workpiece more precise and meeting higher production process requirements.

[0014] Preferably, the assembly line includes a wire rack, a long groove arranged along the length direction of the wire rack, and limiting roller wheels arranged on both sides of the long groove; the limiting roller wheels are adjustable along the width direction of the wire rack.

[0015] By adopting the above technical solution, the optimized design of the assembly line structure is realized. The assembly line consists of a wire rack, a long groove and limiting roller wheels, which can effectively support and guide the workpiece to be stably conveyed along a predetermined path. The limiting roller wheels are adjustable along the width direction of the wire rack, enabling the equipment to adapt to workpieces of different sizes or specifications, and improving the flexibility and compatibility of production.

[0016] Preferably, the driving device includes a guide rail fixed to the wire rack below the long groove, a rack arranged on the side wall of the guide rail, and a driving component that reciprocates along the length direction of the long groove and meshes with the rack.

[0017] By adopting the above technical solution, the precise control and efficient transmission of the driving device can be realized. The combined design of the guide rail and the rack ensures the stable operation of the driving component on the wire rack. At the same time, by using the meshing relationship between the rack and the driving component, the precise positioning of the feeding position of the workpiece is achieved. This structure not only improves the overall stability of the equipment, but also effectively reduces the problem of error accumulation that may be brought by traditional transmission methods, thereby significantly improving the production efficiency and product quality.

[0018] Preferably, the driving component includes a sliding seat slidably matched with the guide rail, a driving motor arranged at one end of the sliding seat, and a clamping component arranged at the other end of the sliding seat; a gear meshing with the rack is arranged at the power output end of the driving motor.

[0019] By adopting the above technical solution, the driving component can achieve precise and stable power transmission, ensuring the accurate positioning of the workpiece on the assembly line. The sliding fit between the sliding seat and the guide rail ensures the smooth operation of the entire driving component. The driving motor drives the gear to mesh with the rack, further improving the reliability and controllability of power transmission. This design not only improves the stability during the feeding process of the workpiece, but also effectively reduces the processing deviation caused by power transmission errors, thereby significantly improving the processing accuracy and consistency of the product.

[0020] Preferably, the clamping assembly includes a clamping table fastened to the sliding seat, a clamping seat slidably arranged on the clamping table, a first cylinder fastened to the clamping table for driving the clamping seat to reciprocate in the height direction of the assembly line, and a clamping mechanism arranged on the clamping seat for clamping and feeding the workpiece.

[0021] By adopting the above technical solution, the height-adjustable function of the clamping assembly is realized. The clamping seat can reciprocate relative to the clamping table in the height direction of the assembly line, which is driven by the first cylinder. This design enables the clamping assembly to adapt to workpieces of different thicknesses or sizes, improving the versatility and flexibility of the equipment. At the same time, the clamping mechanism is arranged on the clamping seat, ensuring stable clamping of the workpiece during feeding, thereby improving the machining accuracy and efficiency.

[0022] Preferably, the clamping mechanism includes a clamping jaw pivotally connected to one end of the clamping seat, and a second cylinder pivotally connected to the other end of the clamping seat; the piston rod of the second cylinder is pivotally connected to the clamping jaw and is used to drive the clamping end of the clamping jaw to turn up and down around the pivot axis of the clamping jaw; when the clamping jaw is driven by the second cylinder to turn downwards, the workpiece is clamped; when the clamping jaw is driven by the second cylinder to turn upwards, it is separated from the workpiece; the clamping mechanism cooperates with the long groove and reciprocates along the long groove; the pivot axis of the clamping jaw is arranged at the clamping end of the clamping jaw and the clamping jaw is arc-shaped.

[0023] By adopting the above technical solution, the pivot axis of the clamping jaw being arranged at the clamping end of the clamping jaw can make the force arm shorter, requiring less driving force when the second cylinder drives the clamping jaw to turn, thereby improving the action efficiency and reducing energy consumption; at the same time, designing the clamping jaw as arc-shaped not only facilitates the connection with the pivot end of the second cylinder, but also can better control the clamping force, making the clamping more stable and reliable, reducing the risk of workpiece surface damage caused by excessive local pressure. In addition, this structure cooperates with the long groove and reciprocates therein, ensuring the smoothness and accuracy of the entire clamping process, further improving the accuracy and quality of the equipment's automated production.

[0031] The embodiments of the present application disclose an automatic production device for punching convex hulls. This device is mainly used for punching convex hulls at the bending parts of bending parts similar to bridge frames, so as to increase the strength of the bending parts of the bridge frame through the convex hulls.

[0032] Combined with Figure 1 As shown, the automatic production device includes an automatic production line and a convex hull machine. Among them, the convex hull machine 2 is installed on one side of the automatic production line 1 and is used for punching convex hulls on the workpieces conveyed to the processing position; preferably, the automatic production line 1 includes a production line 11 and a driving device 12 for driving the workpieces on the production line 11 to automatically feed forward according to the punching frequency of the convex hull machine 2, so as to efficiently and automatically complete the punching of the convex hull 31 at the bending part of the workpiece. The convex hull 31 punched in this way has accurate punching positions and good consistency, and is time-saving and efficient.

[0033] Furthermore, combined withFigures 2 to 6 As shown, the above-mentioned bulging machine 2 includes a frame 21, an upper die head 22, a die base 23, a lower die head 24, and a first driving component 25 and a second driving component 26 for respectively driving the corresponding upper die head 22 and lower die head 24 to move; as Figure 4 shown, since the bulging position is at the bending part of the U-shaped workpiece, in order to accurately punch this position, an inclined surface for installing the above-mentioned first driving component 25 is provided at the upper end of the frame 21, so that the upper die head 22 connected to the driving end of the first driving component 25 can more accurately punch the bending part of the workpiece.

[0034] Furthermore, as Figure 2 shown, a die base 23 is horizontally installed in the middle of the frame 21. A step 232 is provided on one side wall of the die base 23 facing the upper die head 22, so that the two bending walls at the bending part of the workpiece can be closely attached to the two step surfaces of the step 232, thereby realizing accurate positioning of the workpiece during the processing; in addition, a guiding hole 231 is penetrated through the corner of the step 232, so as to ensure that the lower die head 24 can stably slide in the guiding hole 231 and cooperate with the upper die head 22, further improving the quality and accuracy of the bulging forming.

[0035] The included angle between the axis of the above-mentioned guiding hole 231 and the horizontal plane of the step 232 is greater than 15 degrees and less than 60 degrees. Preferably, the included angle is set to 45 degrees, which can ensure that the lower die head 24 has an appropriate inclination angle when punching the workpiece, thereby improving the stability of the punching process and effectively avoiding the phenomenon of the workpiece shifting or jamming during the processing. At the same time, this design can also improve the quality and consistency of the bulging forming, making the bulging formed at the bending part of the workpiece more accurate and meeting the higher production process requirements.

[0036] Similar to the installation of the above-mentioned first driving component 25, an inclined surface for installing the second driving component 26 is also provided below the frame 21, and a lower die head 24 capable of smoothly sliding along the above-mentioned guiding hole 231 is provided at the driving end of the second driving component 26; in order to be able to drive the upper die head 22 and the lower die head 24 to efficiently and quickly punch the required-shaped bulge 31 at the bending part of the workpiece, both the first driving component 25 and the second driving component 26 are set as air cylinders, so as to reduce the waiting time and efficiently and quickly punch on both sides of the bending part of the workpiece.

[0037] In addition, in order to facilitate adapting to the modular design of the upper die head 22 and the lower die head 24, the upper die head 22 and the lower die head 24 are respectively detachably connected to the corresponding first driving component 25 and second driving component 26. At the same time, a convex die is provided on the end face of the upper die head 22, and a concave die is provided on the end face of the lower die head 24, so as to conveniently and quickly replace the corresponding die according to the different shapes of the bulges of different workpieces.

[0038] Furthermore, in combination with Figure 7 As shown, the above-mentioned pipeline 11 includes a wire rack 111, a long groove 112 arranged along the length direction of the wire rack 111, and limiting roller wheels 113 vertically installed on both sides of the long groove 112; among them, the limiting roller wheels 113 can be adjustably arranged along the width direction of the wire rack 111, that is, a plurality of mounting holes are distributed on the cross beam arranged along the width direction of the wire rack 111. When applying to workpieces of different sizes or specifications, only the distance between the roller wheels on both sides of the long groove 112 needs to be adjusted, thereby effectively improving the flexibility and compatibility of the pipeline 11.

[0039] Furthermore, in order to better cooperate with the convex hull machine 2 to complete the automatic feeding of workpieces, the above-mentioned driving device 12 includes a guide rail 121 arranged under the long groove 112 and fastened to the wire rack 111, a rack 122 arranged on one side wall of the guide rail 121, and a driving component 123 that reciprocates along the length direction of the long groove 112 and meshes with the rack 122. Preferably, the driving component 123 includes a sliding seat 1231 slidably matched with the guide rail 121, a driving motor 1232 installed at one end of the sliding seat 1231, and a clamping component 1233 installed at the other end of the sliding seat 1231; wherein a gear meshing with the above-mentioned rack 122 is arranged at the power output end of the driving motor 1232. Preferably, the driving motor 1232 can preferably be a stepping motor, thereby realizing the precise positioning of the clamping component 1233.

[0040] Through the above structural design, not only can the precise control and efficient transmission of the driving device 12 be realized, but also through the combined design of the guide rail 121 and the rack 122, the stable operation of the driving component 123 on the wire rack 111 can be effectively ensured. At the same time, by using the meshing relationship between the rack 122 and the driving component 123, the precise positioning of the workpiece feeding position is realized. This structure not only improves the overall stability of the equipment, but also effectively reduces the problem of error accumulation that may be brought by the traditional transmission method, thereby significantly improving the production efficiency and product quality.

[0041] Furthermore, in combination with Figure 9 and Figure 10As shown in the figure, the above-mentioned clamping assembly 1233 includes a clamping table 12331 fastened to the sliding seat 1231, a clamping seat 12332 slidably arranged on the clamping table 12331, a first cylinder 12333 fastened to the clamping table 12331 for driving the clamping seat 12332 to move back and forth in the height direction of the assembly line 11, and a clamping mechanism 12334 arranged on the clamping seat 12332 for clamping and feeding the workpiece; through the first cylinder 12333, the clamping seat 12332 is driven to move back and forth in the height direction of the assembly line 11 relative to the clamping table 12331. This design enables the clamping assembly 1233 to adapt to workpieces of different thicknesses or sizes, thereby improving the versatility and flexibility of the equipment; at the same time, by arranging the clamping mechanism 12334 on the clamping seat 12332, the clamping mechanism can be driven to move back and forth along the long groove 112 through the fastening of the clamping table 12331 and the sliding seat 1231, and then drive the workpiece to feed to the processing position of the bulging machine 2.

[0042] Furthermore, in combination with Figure 10 As shown in the figure, the above-mentioned clamping mechanism 12334 includes a claw 123341 pivotally connected to one end of the clamping seat 12332, and a second cylinder 123342 pivotally connected to the other end of the clamping seat 12332; wherein, the piston rod of the second cylinder 123342 is pivotally connected to the claw 123341 and is used to drive the clamping end of the claw 123341 to turn up and down around the pivot axis of the claw 123341; that is, when the claw 123341 is driven by the lever thrust of the second cylinder 123342 to turn downwards, the workpiece is clamped; when the claw 123341 is driven by the lever traction of the second cylinder 123342 to turn upwards, it is separated from the workpiece; in order to further control the clamping force of the claw 123341, the pivot axis of the claw 123341 is arranged at the clamping end of the claw 123341, so that the force arm of the clamping end is shorter, and the driving force required when the second cylinder 123342 drives the claw 123341 to turn is smaller, thereby improving the action efficiency and reducing the energy consumption; at the same time, the claw 123341 is designed as an arc shape, which not only facilitates the connection with the pivot end of the second cylinder 123342, but also can better control the clamping force, making the clamping more stable and reliable, and reducing the risk of workpiece surface damage caused by excessive local pressure.

[0043] The implementation principle of this application is as follows: When the automatic production equipment is working, the workpiece is placed on the assembly line 11, and the distance between the limit rollers 113 on the assembly line 11 is adjusted according to the width of the workpiece, so that the workpiece can move along the assembly line 11 without deviation; at the same time, the sliding seat 1231 of the driving device 12 moves back and forth along the long groove 112 under the cooperation of the guide rail 121 and the rack 122, and the jaws 123341 of the clamping assembly 1233 clamp the end of the workpiece away from the bulging machine 2 under the drive of the second cylinder 123342. At the same time, the clamping seat 12332 can be lifted by the first cylinder 12333, so that the lower bottom surface of the workpiece can be kept flush with the step 232 surface of the die base 23. Then, under the drive of the drive motor 1232 in the driving device 12, the workpiece is sent to the processing position of the bulging machine 2. After that, the first driving component 25 of the bulging machine 2 pushes the upper die head 22, and the second driving component 26 pushes the lower die head 24. The two cooperate to punch the bending part of the workpiece to form a bulge; after the punching is completed, the jaws 123341 release the workpiece, and the sliding seat 1231 drives the clamping assembly 1233 to return, preparing for the feeding of the next workpiece. The whole process is completed automatically, improving the production efficiency and product quality.

[0044] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
