[0002] At present, in the production process of thermos cups, stamping equipment is widely used in the processing and manufacturing of cup lids, cup bodies and other parts. However, existing stamping equipment usually adopts a single-mold and single-station design, that is, it can only process one stamping part at a time. This design leads to low production efficiency, especially in mass production, the stamping cycle is long, the operation is cumbersome, and the overall efficiency of the production line is difficult to improve. In addition, the unloading process in existing equipment usually requires manual operation, which not only increases the labor intensity, but also may cause product damage or reduce production efficiency due to improper operation or negligence.

The rotating rod is driven by the double-axis motor to rotate, and further drives multiple lower dies to rotate. After the stamping parts inside the lower die are stamped, the lower die is moved to the discharge port at the bottom of the mounting cylinder through the rotation of the rotating rod. The movement of the L-shaped rod drives the swing rod and the ejector rod to swing, which further drives the top plate to move downward, and automatically ejects the stamping parts inside the lower die.

[0014] The stamping method adapted for the thermos cup production line includes the following steps:

[0015] Step 1: First, the thermos cup cover is transported by starting the transport device. At this time, the electric suction cup moves the electric suction cup to the output port of the transport device under the cooperation of the electric guide rail and the electric slider, and the thermos cup cover is moved to the forming cavity inside the lower mold by the electric suction cup. At this time, the upper mold is driven downward by starting the electric telescopic rod until the upper mold and the lower mold are closed, so that a stamping part is formed in the forming cavity of the lower mold;

[0016] Step 2: After the stamping is completed, the output end of the electric telescopic rod drives the upper die to move upward, thereby driving the movable rod to move synchronously, and further moving the rubber piston along the inner wall of the installation cavity, so that the air inside the fixed cylinder is discharged through the connecting pipe, and finally the gas is discharged through the exhaust pipe. The debris on the bottom surface of the upper die is cleaned by the flowing gas. Similarly, when the upper die moves downward, it drives the movable rod to reset. At this time, the outside air enters the interior of the installation cavity through the air intake pipe, preparing for the next cleaning;

Furthermore, when the lower mold in the present invention moves to the output port of the mounting cylinder, the internal ejection assembly can automatically eject the stamping parts, realizing the function of automatic unloading, which not only reduces manual intervention and labor intensity, but also avoids product damage or reduced production efficiency due to improper manual operation. In addition, the present invention also has an automatic loading function, which enables the entire stamping production line to be automated, reduces manual operation links, reduces production costs, and also improves the safety of the production line.

[0020] 2.

[0029] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please see attached Figure 1 -Attached Figure 7The embodiment of the present invention provides a stamping device suitable for a thermos cup production line, including a body 1, a mounting cylinder 901 is installed on the inner side of the body 1, a plurality of lower molds 902 are fixedly connected to the inner side of the mounting cylinder 901 at equal intervals, a mounting groove 903 is provided inside the lower mold 902, an L-shaped rod 904 is slidably connected inside the mounting groove 903, a spring 905 is sleeved on the outer side of the L-shaped rod 904, one end of the L-shaped rod 904 is rotatably connected to a swing rod 906, one end of the swing rod 906 is hinged to a push rod 907, the top of the push rod 907 is fixedly connected to a top plate 908, two through grooves 909 are provided on the outer surface of the lower mold 902, a fixing frame 805 is fixedly installed on the outer side of the body 1, and a fixing frame 805 is fixedly installed on the outer side of the body 1. A dual-axis motor 803 is installed on the outside of the frame 805, and one of the output ends of the dual-axis motor 803 is fixedly connected to a rotating rod 804. The outer surface of the installation cylinder 901 is sequentially provided with an input port and an output port. The dual-axis motor 803 drives the rotating rod 804 to rotate, and further drives the multiple lower molds 902 to rotate. After the stamping parts inside the lower mold 902 are stamped, the lower mold 902 is moved to the discharge port at the bottom of the installation cylinder 901 through the rotation of the rotating rod 804. The movement of the L-shaped rod 904 drives the swing rod 906 and the ejector rod 907 to swing, and further drives the ejector plate 908 to move downward, and the stamping parts inside the lower mold 902 are automatically ejected. One end of the spring 905 is fixedly connected to the inner wall of the installation groove 903, and the other end of the spring 905 is fixedly connected to the inner side of the L-shaped rod 904.

[0031] Specifically, the body 1 serves as the frame of the entire device and provides a stable support. The mounting cylinder 901 is fixedly mounted on the inner side of the body 1. As a carrier of the stamping die, a plurality of lower dies 902 are equidistantly fixedly connected to the inner side of the mounting cylinder 901. This layout design ensures that a plurality of lower dies 902 can work simultaneously, thereby improving the overall work efficiency of the production line. The function of the spring 905 is to ensure that the lower die 902 can return to its initial state after the stamping process and maintain the efficient operation of the system. The swing rod 906 is connected to the L-shaped rod 904, and its function is to convert the movement of the L-shaped rod 904 into a more precise linear or swinging motion, thereby driving the ejector rod 907 and the top plate 908 to move up and down, so as to realize the ejection of the stamping parts in the lower die 902. The downward movement of the top plate 908 automatically ejects the conditions for stamping completion through physical thrust, avoiding manual intervention, which not only reduces the labor intensity, but also improves the safety and accuracy of the operation.

[0032] In order to ensure the efficient movement of the lower die 902 during operation, the equipment drives the rotating rod 804 to rotate through the dual-axis motor 803. When the dual-axis motor 803 is started, the rotating rod 804 drives the multiple lower dies 902 to rotate 60 degrees, so that the lower dies 902 move to different working positions in sequence along the circumferential track of the mounting cylinder 901. This rotation not only optimizes the stamping layout of the workpiece, but also can process multiple stamping parts in the same cycle, greatly improving production efficiency.

[0033] When the lower die 902 completes a stamping operation, it will move to the output port of the mounting cylinder 901. At this time, the device controls the precise positioning of the lower die 902 through the cooperation of the driving gear 801, the driving rack 806 and the limit frame 802. By driving the L-shaped rod 904 to move synchronously, the swing rod 906 begins to swing, and the ejector rod 907 and the top plate 908 move downward accordingly, ejecting the stamping parts inside the lower die 902, and realizing automatic unloading. This process is fully automated, avoiding the uncertainty in manual operation and improving the continuity and stability of the production line.

[0034] The other output end of the dual-axis motor 803 is fixedly connected to the driving gear 801, and two limit frames 802 are fixedly connected to the inner side of the body 1. The top of the limit frame 802 is slidably connected to the driving rack 806, and the outer side of the driving rack 806 is fixedly connected to the fixed tube 807. The outer sides of the two driving racks 806 are meshed with the outer sides of the driving gear 801, and the outer wall diameter of the fixed tube 807 matches the inner wall diameter of the through groove 909.

[0035] Specifically, by starting the other output end of the dual-axis motor 803, the driving gear 801 is driven to move synchronously, and the two driving racks 806 are driven to approach each other along the inner wall of the limit frame 802, and the end of the fixed tube 807 is moved along the inner wall of the through groove 909, thereby driving the L-shaped rod 904 to move, and cooperating with the top plate 908 to eject the stamping part.

[0036] A support frame 2 is fixedly connected to one side of the top of the body 1, an electric telescopic rod 5 is installed on the top of the support frame 2, an upper mold 6 is fixedly connected to the output end of the electric telescopic rod 5, and a cleaning component is installed on the top of the support frame 2, which is used to clean the debris adhering to the outer surface of the upper mold 6 after stamping is completed.

[0037] The cleaning assembly includes a fixed cylinder 703, which is fixedly connected to the top of the support frame 2, and an installation cavity 706 is provided inside the fixed cylinder 703. A rubber piston 705 is slidably connected inside the installation cavity 706, and a movable rod 704 is fixedly connected to the outside of the rubber piston 705. The outside of the fixed cylinder 703 is connected to a connecting pipe 701 and an air inlet pipe 702 in sequence. Both the connecting pipe 701 and the air inlet pipe 702 are provided with a one-way valve, and the conduction directions of the two one-way valves are opposite. The bottom end of the installation cavity 706 is fixedly connected to the top of the upper mold 6, and one end of the connecting pipe 701 is fixedly connected to an air jet pipe, and a plurality of spray holes are provided on the outer surface of the air jet pipe.

[0038] Specifically, the support frame 2 provides a support structure for the installation of the upper die 6. In order to realize the lifting and lowering movement of the upper die 6, an electric telescopic rod 5 is installed on the top of the support frame 2. Driven by the electric telescopic rod 5, the upper die 6 can move up and down accurately. When the output end of the electric telescopic rod 5 drives the upper die 6 to move downward, the upper die 6 and the lower die 902 are closed to complete the stamping operation. After the stamping is completed, the electric telescopic rod 5 lifts the upper die 6 upward to prepare for the next stamping action.

[0039] One-way valves are installed in the connecting pipe 701 and the air inlet pipe 702. The two one-way valves are turned in opposite directions to ensure that the flow direction of air or gas is consistent with the operation requirements. Specifically, the connecting pipe 701 is connected to the installation cavity 706, and an air jet is installed at the other end of the connecting pipe 701. A plurality of spray holes are provided on the outer surface of the air jet for releasing airflow.

[0040] After the upper mold 6 completes the stamping work, the electric telescopic rod 5 drives the upper mold 6 to move upward. As the upper mold 6 rises, the movable rod 704 moves synchronously, thereby pushing the rubber piston 705 to slide in the installation cavity 706, thereby squeezing the air in the fixed cylinder 703 to flow out. Through the connecting pipe 701, the air is discharged and sprayed out through the jet pipe. The sprayed airflow acts on the bottom surface of the upper mold 6 through the spray hole, effectively cleaning the debris and sundries adhering to the surface of the upper mold 6. At the same time, during the upward movement of the upper mold 6, the one-way valve of the air inlet pipe 702 is opened, and the outside air enters the installation cavity 706 through the air inlet pipe 702 to prepare the air source for the next cleaning.

[0041] A transport device 3 is installed on one side of the top of the body 1, and the transport device 3 is used to transport the cup cover of the thermos cup. A collection bucket is arranged at the bottom of the body 1, and the collection bucket is used to collect the completed cup cover stamping parts.

[0042] Two electric guide rails 401 are installed on the top of the body 1 , an electric slider 402 is installed outside the electric guide rail 401 , a connecting frame 403 is detachably connected to the top of the electric slider 402 , and an electric suction cup 404 is installed inside the connecting frame 403 .

[0043] Specifically, the electric slider 402 is installed outside the electric guide rail 401. The electric slider 402 is a component that can move along the electric guide rail 401, and its movement is completed by the driving system of the electric guide rail 401. The main function of the electric suction cup 404 is to absorb the thermos cup cover and move it to a designated position. The working principle of the electric suction cup 404 is generally based on electric control, and the target object can be fixed on its surface through the adsorption force until the handling task is completed.

[0044] When the transport device 3 is started, it starts to drive the transport of the thermos cup cover. During this process, the cooperation of the electric guide rail 401 and the electric slider 402 enables the electric suction cup 404 to accurately move along the track of the guide rail, bringing the suction cup to the output port of the transport device 3. After reaching the output port, the electric suction cup 404 fixes the thermos cup cover through its adsorption function, and then transports it to the molding cavity of the lower mold 902.

[0045] The stamping method adapted for the thermos cup production line includes the following steps:

[0046] Step 1: First, the thermos cup cover is transported by starting the transport device 3. At this time, the electric suction cup 404 moves the electric suction cup 404 to the output port of the transport device 3 under the cooperation of the electric guide rail 401 and the electric slider 402. The thermos cup cover is moved to the molding cavity inside the lower mold 902 by the electric suction cup 404. At this time, the upper mold 6 is driven to move downward by starting the electric telescopic rod 5 until the upper mold 6 and the lower mold 902 are combined, so that a stamping part is formed in the molding cavity of the lower mold 902;

[0047] Step 2: After the stamping is completed, the output end of the electric telescopic rod 5 drives the upper mold 6 to move upward, thereby driving the movable rod 704 to move synchronously, and further moving the rubber piston 705 along the inner wall of the installation cavity 706, so that the air inside the fixed cylinder 703 is discharged through the connecting pipe 701, and finally the gas is discharged through the exhaust pipe, and the debris on the bottom surface of the upper mold 6 is cleaned by the flowing gas. Similarly, when the upper mold 6 moves downward, it drives the movable rod 704 to reset. At this time, the outside air enters the interior of the installation cavity 706 through the air inlet pipe 702, preparing for the next cleaning;

[0048] Step 3. When one of the lower molds 902 located on the inner side of the mounting cylinder 901 is stamped, the dual-axis motor 803 is started to drive the rotating rod 804 to rotate 60°, and the lower mold 902 without stamping parts in the molding cavity is moved to the input port of the mounting cylinder 901, and step 1 is repeated. When the lower mold 902 moves to the output port of the mounting cylinder 901, the other output end of the dual-axis motor 803 is started, so as to drive the driving gear 801 to move synchronously, drive the two driving racks 806 to approach each other along the inner wall of the limit frame 802, and move the end of the fixed tube 807 along the inner wall of the through groove 909, and further drive the L-shaped rod 904 to move synchronously. As the L-shaped rod 904 moves, one end of the swing rod 906 is driven to swing, and under the traction force of the swing rod 906, the ejector rod 907 and the ejector plate 908 are driven to move downward, and the stamping parts inside the lower mold 902 are ejected, thereby realizing automatic unloading.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

At this time, the upper mold (6) is driven to move downward by starting the electric telescopic rod (5) until the upper mold (6) and the lower mold (902) are combined, so that a stamping part is formed in the molding cavity of the lower mold (902); Step 2: After the stamping is completed, the output end of the electric telescopic rod (5) drives the upper mold (6) to move upward, thereby driving the movable rod (704) to move synchronously, and further moving the rubber piston (705) along the inner wall of the installation cavity (706), so that the air inside the fixed cylinder (703) is discharged through the connecting pipe (701), and finally the gas is discharged through the exhaust pipe, and the debris on the bottom surface of the upper mold (6) is cleaned by the flowing gas. Similarly, when the upper mold (6) moves downward, it drives the movable rod (704) to reset, and at this time, the outside air enters the interior of the installation cavity (706) through the air inlet pipe (702), preparing for the next cleaning; Step 3: When the stamping of one of the lower dies (902) located inside the installation cylinder (901) is completed, the dual-axis motor (803) is started to drive the rotating rod (804) to rotate 60 degrees, and the lower die (902) without the stamped part in the molding cavity is moved to the input port of the installation cylinder (901), and step 1 is repeated. When the lower die (902) moves to the output port of the installation cylinder (901), the other output end of the dual-axis motor (803) is started, so that the driving gear (801) is driven to move synchronously, and the belt The two driving racks (806) are moved closer to each other along the inner wall of the limiting frame (802), and the end of the fixed tube (807) is moved along the inner wall of the through groove (909), which further drives the L-shaped rod (904) to move synchronously. As the L-shaped rod (904) moves, one end of the swing rod (906) is driven to swing. Under the traction force of the swing rod (906), the ejector rod (907) and the ejector plate (908) are driven to move downward, and the stamping parts inside the lower die (902) are ejected, thereby realizing automatic unloading.
