Description

Technical Field

[0001] This utility model belongs to the field of stamping equipment technology, specifically relating to a continuous stamping equipment with waste material punching. Background Technology

[0002] In modern industrial production, continuous stamping equipment is widely used in many fields such as automobiles, electronics, and home appliances to achieve efficient and precise metal sheet processing. Its working principle is to complete multiple processes such as punching, blanking, and forming on the sheet through continuous stamping action, thereby quickly mass-producing various parts.

[0003] However, some irregularly shaped or large-area waste materials get stuck and blocked in the waste trough, unable to be discharged smoothly. This causes them to bounce around on the workpiece and the stamping machine due to vibration, interfering with subsequent stamping operations. These abnormal waste phenomena not only seriously affect the normal operation of the equipment, increase the frequency of equipment shutdown for cleaning, and reduce production efficiency, but may also cause damage to the equipment and increase maintenance costs due to accidental impacts of the waste materials on the mold or other parts of the machine tool.

[0004] In view of the shortcomings of the existing technology, it is necessary to propose a continuous stamping equipment with waste punching. Utility Model Content

[0005] The purpose of this invention is to provide a continuous stamping equipment with waste material punching, which can pre-stamp the waste material so that it no longer remains in a whole state, thus making it easier and smoother to fall from the waste material trough on the stamping machine, effectively preventing waste material from jumping around and other abnormal situations.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A continuous stamping device for punching waste material includes a stamping machine tool, an mounting plate is mounted on the upper side of the stamping machine tool, a hydraulic cylinder is fixed on one side of the mounting plate, a telescopic rod is provided at the bottom end of the hydraulic cylinder, and a mounting column is mounted at the bottom end of the telescopic rod.

[0008] The mounting column is equipped with a lower mounting groove, and a waste material stamping structure is installed in the lower mounting groove.

[0009] The waste stamping structure includes a push rod motor fixed at the top of the lower mounting groove. A stamping plate is fixed vertically downward on the stroke rod of the push rod motor. An upper mounting groove is provided inside the mounting column and at the bottom of the lower mounting groove. The upper mounting groove is connected to the lower mounting groove. The stamping plate is assembled in the upper mounting groove. Both ends of the stamping plate are strip-shaped structures and are in contact with the inner wall of the upper mounting groove.

[0010] The inner wall of the upper mounting groove is provided with blocking plates on both sides of the stamping sheet, and the blocking plates are in contact with the stamping sheet.

[0011] The bottom end of the upper mounting groove is provided with an annular conical surface.

[0012] The top of the mounting column is provided with a threaded column, the inside of the telescopic rod is provided with a threaded groove, and the threaded column is threadedly connected to the threaded groove. The telescopic rod is provided with a mounting chamber inside and outside the mounting column. A sliding frame is slidably connected inside the mounting chamber and is located outside the mounting column. A spring is installed inside the mounting chamber and abuts against the sliding frame.

[0013] A snap-fit ​​structure is installed between the mounting column and the sliding frame.

[0014] The snap-fit ​​structure includes at least one second snap-fit ​​block fixed to the outside of the mounting post and a plurality of first snap-fit ​​blocks fixed to the inner wall of the sliding frame, wherein the second snap-fit ​​block and the first snap-fit ​​block snap-fit ​​each other.

[0015] The technical effects achieved by this utility model are as follows:

[0016] When stamping a workpiece, this invention first pre-stamps the waste material of the pre-stamped structure through a push rod motor and a stamping plate, so that it no longer maintains a whole state, thus making it easier and smoother to fall from the waste tray on the stamping machine tool. This effectively prevents the waste material from jumping around and other abnormal situations, thereby significantly improving the operational stability, production efficiency and service life of the continuous stamping equipment.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-6 As shown, a continuous stamping equipment with waste punching includes a stamping machine tool 1, an mounting plate 2 is mounted on the upper side of the stamping machine tool 1, a hydraulic cylinder 3 is fixed on one side of the mounting plate 2, a telescopic rod 4 is provided at the bottom end of the hydraulic cylinder 3, and a mounting column 5 is mounted at the bottom end of the telescopic rod 4. The hydraulic cylinder 3 can be other equipment or structures that can punch holes.

[0027] The stamping machine tool 1 is provided with threaded rods on both the left and right sides for moving the truss on it. The mounting plate 2 can be mounted on the truss when it is movable, so that the position of the mounting plate 2 can be adjusted to perform continuous stamping action. The stamping machine tool 1 is existing technology and will not be described in detail here.

[0028] When punching a workpiece, the hydraulic cylinder 3 can be driven, which in turn causes the lower telescopic rod 4 to move downward and move the mounting column 5, so that the mounting column 5 contacts the workpiece, thereby enabling the workpiece to be punched.

[0029] The mounting column 5 is fitted with a lower mounting groove 10, and a waste material stamping structure is installed in the lower mounting groove 10.

[0030] See attached document Figure 3 The waste stamping structure includes a push rod motor 6 fixed at the top of the lower mounting groove 10. The push rod motor 6 can be other punching equipment or structures. The stroke rod of the push rod motor 6 is vertically fixed with a stamping plate 7. An upper mounting groove 9 is provided inside the mounting column 5 and located at the bottom of the lower mounting groove 10. The upper mounting groove 9 is connected to the lower mounting groove 10. The stamping plate 7 is assembled in the upper mounting groove 9. The two ends of the stamping plate 7 are strip-shaped structures and are in contact with the inner wall of the upper mounting groove 9.

[0031] When stamping a workpiece, the scrap material at the center of the pre-stamped workpiece is first stamped. At this time, the push rod motor 6 is driven, causing the push rod motor 6 to move the stamping plate 7 downwards. This allows the stamping plate 7 to stamp the center of the workpiece, removing a portion of the scrap material. Both ends of the stamping plate 7 contact the inner wall of the upper mounting groove 9. (Refer to the attached...) Figure 3 The bottom of the upper mounting groove 9 is provided with an annular conical surface, so that the diameter of the stamped scrap is approximately the same as the diameter of the inner wall of the upper mounting groove 9, thus achieving a separation effect of the scrap. Then, the hydraulic cylinder 3 is driven, so that the output end of the hydraulic cylinder 3 drives the telescopic rod 4 and the mounting column 5 to stamp the workpiece. At this time, the overall structure of the scrap stamped by the stamping sheet 7 is close to being separated, making it easy to fall from the evenly arranged scrap groove on the stamping machine tool 1, avoiding the scrap remaining on the stamping machine tool 1, preventing the scrap from jumping, and avoiding interference with subsequent stamping steps.

[0032] See attached document Figure 4 The inner wall of the upper mounting groove 9 and both sides of the stamping sheet 7 are provided with blocking plates 8, and the blocking plates 8 are in contact with the stamping sheet 7. This arrangement allows the blocking plates 8 to prevent stamping waste or other dust from entering the upper side of the upper mounting groove 9 or the interior of the lower mounting groove 10, thereby protecting the components inside the lower mounting groove 10.

[0033] See attached document Figure 5 The top of the mounting column 5 is provided with a threaded column 11, and the inside of the telescopic rod 4 is provided with a threaded groove 12. The threaded column 11 and the threaded groove 12 are threadedly connected. The telescopic rod 4 is provided with a mounting chamber 13 inside and outside the mounting column 5. A sliding frame 14 is slidably connected inside the mounting chamber 13 and is located outside the mounting column 5. A spring 15 is installed inside the mounting chamber 13 and abuts against the sliding frame 14. A snap-fit ​​structure is installed between the mounting column 5 and the sliding frame 14. (See attached diagram) Figure 6 The snap-fit ​​structure includes at least one second snap-fit ​​block 17 fixed to the outside of the mounting post 5 and a plurality of first snap-fit ​​blocks 16 fixed to the inner wall of the sliding frame 14, and the second snap-fit ​​block 17 and the first snap-fit ​​block 16 snap-fit ​​each other.

[0034] When installing the mounting post 5, the threaded post 11 can be screwed into the threaded groove 12 until the second locking block 17 contacts the first locking block 16. At this time, in order to avoid the first locking block 16 obstructing the upward movement of the second locking block 17, the sliding frame 14 can be moved upward, thereby causing the sliding frame 14 to retract into the mounting chamber 13 and compress the spring 15. Continue to screw the threaded post 11 until the mounting post 5 abuts against the telescopic rod 4. At this time, the sliding frame 14 can be released, allowing the sliding frame 14 to reset through the spring 15, and causing the first locking block 16 and the second locking block 17 to engage with each other. Through this setting, the vibration generated during operation that could cause the mounting post 5 to rotate will be blocked by the first locking block 16, thereby preventing the threaded post 11 from rotating out of the threaded groove 12 and ensuring the firmness of the mounting post 5.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
