Description

Technical Field

[0001] This utility model belongs to the technical field of stamping forming equipment, specifically relating to a continuous stamping forming equipment with waste discharge. Background Technology

[0002] In modern industrial production, continuous stamping is widely used in many fields such as automobile manufacturing, electronic equipment manufacturing, and hardware processing due to its high efficiency and high precision. As the market demand for stamped products continues to increase, higher requirements are also placed on the performance and efficiency of continuous stamping equipment. In traditional continuous stamping equipment, the removal of waste material during the stamping process has always been a problem that needs to be solved. If waste material cannot be removed in a timely and effective manner during continuous stamping, it will cause many serious problems. First, the accumulation of waste material in the die holder will affect the normal opening and closing of the die holder, causing the stamping action to be obstructed, reducing production efficiency, and may even cause damage to the die holder, increasing maintenance costs and downtime. Second, if waste material remains on the surface of the workpiece, it will cause scratches, indentations and other defects on the surface of the workpiece in subsequent stamping processes, seriously affecting product quality and increasing the scrap rate.

[0003] Currently, existing stamping forming equipment uses manual waste removal, which is not only inefficient and labor-intensive, but also difficult to guarantee the timeliness of manual cleaning, failing to meet the high-efficiency production requirements of continuous stamping and making it difficult to achieve stable and reliable waste discharge. Utility Model Content

[0004] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a continuous stamping forming device with waste discharge.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A continuous stamping forming apparatus with waste discharge includes a worktable, a lower die base mounted on the top of the worktable, a stamping groove for placing stamping sheet metal inside the lower die base, sheet metal conveying mechanisms mounted on both sides of the worktable, support columns mounted on the four sides of the top of the worktable, a top plate mounted on the top of the support columns, a hydraulic cylinder mounted at the center of the top plate, an upper die base mounted at the power output end of the hydraulic cylinder, several stamping heads of different shapes mounted at the bottom of the upper die base, a discharge groove provided at the corresponding stamping head of the lower die base, a discharge cavity provided on the inner side of the worktable, the output end of the discharge groove communicating with the discharge cavity, a base mounted on the four sides of the bottom of the discharge cavity, a spring mounted on the top of the base, a lock seat mounted on the top of the spring, a vibration guide plate mounted on the top of the lock seat, the vibration guide plate being inclined, a vibration motor mounted at the bottom of the vibration guide plate, and a discharge port provided at the output end of the discharge cavity of the worktable.

[0007] Further defining the sheet metal conveying mechanism, it includes a frame installed at the input and output ends of the lower die base. A drive roller is rotatably mounted on the lower side of the frame, and a synchronization assembly is installed between the two drive rollers. One drive roller is connected to a drive wheel, which is connected to a drive belt. A rotating wheel is connected to the other side of the drive belt, and the rotating wheel is connected to a coupling. The coupling is connected to a drive motor, which is mounted on a worktable. Clearance grooves are provided on both sides of the top of the frame. Telescopic rods are installed within these grooves, and bearing seats are connected to the telescopic rods. The bearing seats are slidably disposed within the clearance grooves. An auxiliary roller is rotatably mounted between the two bearing seats, and a pressing spring is installed on the top of each bearing seat. The free end of the pressing spring is installed on the top of the clearance groove. This structural design allows for automatic and continuous conveying, facilitating continuous stamping.

[0008] Furthermore, the synchronization assembly includes synchronization pulleys mounted outside the two drive rollers, with a synchronization belt installed between the two synchronization pulleys. This structural design enables the sheet metal conveying mechanisms on both sides to move synchronously.

[0009] Furthermore, the top of the discharge chute is designed in a trumpet shape. This structural design facilitates the guidance of waste material after stamping.

[0010] Furthermore, the upper mold base has guide rods installed on its four bottom sides, and the lower mold base has guide grooves at the corresponding guide rods. A spring seat is installed in each guide groove, and a buffer spring is installed in each spring seat. A buffer plate is installed at the free end of each buffer spring. This structural design ensures the vertical movement of the upper mold base while also providing a buffering effect.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model adopts a sheet metal conveying mechanism to automatically convey stamping sheets, and uses a hydraulic cylinder to drive the upper die base and stamping head to perform stamping work, replacing manual operation and realizing continuous stamping and forming operations. This greatly reduces the labor intensity of workers and improves the automation level of the production process. At the same time, the active roller in the sheet metal conveying mechanism is driven by a drive motor through components such as a drive belt to rotate, and the auxiliary roller can be automatically adjusted according to the sheet metal thickness under the action of the pressing spring to press the sheet metal, ensuring the accuracy and stability of sheet metal conveying, which in turn helps to improve stamping precision.

[0013] 2. This utility model, by setting up a discharge chute, discharge chamber, vibrating guide plate and vibrating motor, allows the waste material generated by stamping to automatically enter the discharge chamber through the discharge chute. Under the action of the vibrating motor and spring, the vibrating guide plate vibrates to transport the waste material, avoid waste accumulation, ensure that the waste material is smoothly output from the discharge port, facilitate centralized collection, achieve stable and reliable waste material discharge, and meet the high-efficiency production requirements of continuous stamping.

[0014] 3. This utility model uses the guide rod at the bottom of the upper die base and the guide groove of the lower die base to play a guiding role in the stamping process, thereby improving the stamping accuracy. At the same time, the buffer spring and buffer plate in the guide groove can reduce the impact force during stamping, reduce the damage caused by sudden impact, and assist in pushing the guide rod upward when the die is reset, thereby extending the service life of the equipment and improving the use effect.

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a continuous stamping forming device with waste discharge is described. A lower die base 2 is mounted on the top of a worktable 1. The lower die base 2 has a stamping groove 3 for placing stamping sheets. Sheet material conveying mechanisms 4 are mounted on both sides of the lower die base 2 on the worktable 1. Support columns 5 are mounted on the four sides of the top of the worktable 1. A top plate 6 is mounted on the top of the support columns 5. A hydraulic cylinder 7 is mounted at the center of the top plate 6. An upper die base 8 is mounted at the power output end of the hydraulic cylinder 7. Several stamping heads 9 of different shapes are mounted at the bottom of the upper die base 8. The lower die base 2... A discharge chute 10 is provided at the stamping head 9, and a discharge cavity 11 is provided on the inner side of the worktable 1. The output end of the discharge chute 10 is connected to the discharge cavity 11. A base 12 is installed on the four sides of the bottom of the discharge cavity 11. A spring 13 is installed on the top of the base 12. A lock seat 14 is installed on the top of the spring 13. A vibration guide plate 15 is installed on the top of the lock seat 14. The vibration guide plate 15 is set at an inclination. A vibration motor 16 is installed at the bottom of the vibration guide plate 15. A discharge port 17 is provided at the output end of the discharge cavity 11 of the worktable 1.

[0024] In this embodiment, during use, the stamping sheet is first placed in the sheet conveying mechanism 4 at the input end of the lower die base 2, and the sheet conveying mechanism 4 is started to automatically convey the stamping sheet. After the stamping sheet is conveyed into the stamping groove 3 in the lower die base 2, the hydraulic cylinder 7 is started. The hydraulic cylinder 7 pushes the upper die base 8, and the upper die base 8 pushes the stamping head 9 to move down to stamp the stamping sheet. The waste generated after stamping falls into the discharge groove 10 and is guided by the discharge groove 10 into the vibrating guide plate 15 in the discharge chamber 11. At this time, by starting the vibration motor 16, the vibrating guide plate 15 vibrates under the effect of the vibration motor 16 and the spring 13, and the waste on the vibrating guide plate 15 is vibrated and conveyed to prevent the waste from accumulating on the vibrating guide plate 15. The conveyed waste is output from the discharge port 17 for easy collection in subsequent work.

[0025] The sheet metal conveying mechanism 4 automatically conveys the stamping sheet metal, and the hydraulic cylinder 7 pushes the upper die holder 8. The upper die holder 8 pushes the stamping head 9 down to perform stamping work on the sheet metal, which enables continuous stamping and forming operations, improves the automation level of the device, and reduces labor intensity.

[0026] Example 2, as Figure 2 , Figure 3 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: The sheet material conveying mechanism 4 includes a frame 18 installed at the input and output ends of the lower mold base 2. An active roller 19 is rotatably installed on the lower side of the frame 18. A synchronization component 20 is installed between the two active rollers 19. One active roller 19 is connected to a drive wheel 21, and the drive wheel 21 is connected to a drive belt 22. The other side of the drive belt 22 is connected to a rotating wheel 23, and the rotating wheel 23 is connected to a coupling 24. The coupling 24 is connected to a drive motor 25, and the drive motor 25 is installed on the worktable 1. The top two sides of the frame 18 are provided with clearance grooves 26. A telescopic rod 27 is installed in the clearance groove 26. The telescopic rod 27 is connected to a bearing seat 28. The bearing seat 28 is slidably disposed in the clearance groove 26. An auxiliary roller 29 is rotatably installed between the two bearing seats 28. A pressing spring 30 is installed on the top of the bearing seat 28, and the free end of the pressing spring 30 is installed on the top of the clearance groove 26.

[0027] In this embodiment, during use, the drive motor 25 is started, causing the drive motor 25 to drive the coupling 24, the coupling 24 to drive the rotating wheel 23, the rotating wheel 23 to drive the drive belt 22, the drive belt 22 to drive the drive wheel 21, and the drive wheel 21 to drive the active roller 19 on one side to rotate. When the active roller 19 on one side rotates, the other side of the rotating active roller 19 will synchronously drive the active roller 19 on the other end to rotate through the synchronization component 20, so that the active rollers 19 on both sides of the lower die base 2 perform rotational motion. When the stamping sheet is placed... When the sheet metal is conveyed on the drive roller 19, the auxiliary roller 29 is lifted upwards. After the auxiliary roller 29 moves upwards, it drives the bearing seats 28 on both sides to slide in the clearance groove 26. At the same time, the bearing seats 28 squeeze the telescopic rod 27 and the pressing spring 30, causing the telescopic rod 27 to contract and the pressing spring 30 to compress and deform, and at the same time generate a rebound force on the bearing seats 28. This causes the bearing seats 28 to drive the auxiliary roller 29 to press on the sheet metal, ensuring the accuracy and stability of the sheet metal conveying and improving the stamping precision.

[0028] Example 3, as Figure 1 As shown, this embodiment adds the following structure to the embodiment 2: the synchronization component 20 includes a synchronization belt 32 installed between the two synchronization pulleys 31 and the outside of the two side drive rollers 19.

[0029] In this embodiment, when the active roller 19 on one side rotates, it will synchronously drive the synchronous wheel 31 to rotate. The synchronous wheel 31 drives the synchronous belt 32, and the synchronous belt 32 drives the synchronous wheel 31 on the other side to rotate, thereby causing the synchronous wheel 31 on the other side to drive the active roller 19 to rotate, ensuring that the active rollers 19 on both sides of the lower mold base 2 can rotate synchronously.

[0030] The synchronous pulley 31 and synchronous belt 32 ensure that the active rollers 19 on both sides of the lower die base 2 rotate synchronously during the sheet material conveying process, avoiding sheet material conveying deviation due to inconsistent rotation speeds of the active rollers 19 on both sides, and further improving the stability of sheet material conveying and stamping.

[0031] Example 4, as Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: the top of the discharge trough 10 is set in a trumpet shape.

[0032] In this embodiment, by setting the top of the discharge trough 10 as a funnel-shaped structure, the waste generated after the stamping head 9 stamps the stamping plate can quickly fall into the discharge trough 10, preventing the waste from accumulating and not falling into the discharge trough 10.

[0033] Example 5, as Figure 4As shown, this embodiment adds the following structure based on embodiment 1: guide rods 33 are installed on the four sides of the bottom of the upper mold base 8, and guide grooves 34 are provided on the lower mold base 2 at the corresponding guide rods 33. A spring seat 35 is installed in the guide groove 34, a buffer spring 36 is installed in the spring seat 35, and a buffer plate 37 is installed on the free end of the buffer spring 36.

[0034] In this embodiment, when the upper die holder 8 pushes the stamping head 9 downward to stamp the sheet metal, the upper die holder 8 will simultaneously drive the guide rod 33 to slide along the guide groove 34 of the lower die holder 2, which will guide the movement and improve the stamping accuracy. At the same time, the guide rod 33 will push the buffer plate 37 downward, and the buffer plate 37 will push the buffer spring 36 to compress, reducing the damage caused by the sudden impact. Moreover, when the upper die holder 8 is reset, the rebound force generated by the buffer spring 36 will assist in pushing the guide rod 33 upward, improving the performance.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
