Description

Technical Field

[0001] This utility model relates to the field of copper tube stamping technology, and in particular to a copper tube stamping die. Background Technology

[0002] Copper tubing, as a key component for connection, flow guidance, or structural support, is widely used in refrigeration, sanitary ware, hardware, and many industrial fields. To meet specific functional requirements, copper tubing often needs to undergo stamping and forming processes such as end flattening, punching, and flanging.

[0003] Currently, the industry commonly uses single-station stamping dies or semi-automated equipment for copper tube stamping. A typical operation involves the operator manually placing a single copper tube into the die's positioning slot, then starting the stamping machine to complete the stamping process. Afterward, the formed part is manually removed and a new piece is placed in. Even equipment equipped with simple feeding mechanisms is primarily designed for single-piece, intermittent production cycles, requiring a complete manual or mechanical cycle (part pick-up and unplacing) to be completed before the next cycle can begin.

[0004] Therefore, the existing technical models described above have significant drawbacks in actual production: First, whether operated manually or relying on a single-feeding mechanism, the workflow is dominated by sequential processing of individual parts. That is, the next copper tube cannot be fed and stamped until the previous one has been stamped, demolded, and removed. The waiting time and manual intervention between processes account for an excessively high percentage of the entire production cycle, severely restricting output per unit time and failing to meet the demands of high-efficiency, high-volume production. Second, the equipment has limited functionality and cannot form a continuous workflow. The structural design of existing molds or equipment often focuses on the single stamping action, failing to integrate functions such as material storage, automatic feeding, and finished product ejection. Therefore, further improvement is needed. To this end, we propose a copper tube stamping mold. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and to propose a stamping die for copper tubes.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a stamping die for copper tubes, including a base with a hollow bottom. Multiple support rods are fixed to one side of the upper surface of the base, and a top plate is fixedly connected to the top ends of the multiple support rods. A hydraulic rod is fixed to the upper surface of the top plate, and the telescopic end of the hydraulic rod passes through the top plate and is fixed to a stamping assembly. Multiple punch holes are formed on the top wall of the base below the stamping assembly. A positioning seat is fixed to the upper surface of the base near the punch holes. Multiple transverse positioning grooves aligned with the punch holes are formed at the bottom of the positioning seat. A material storage assembly is fixed to the upper surface of the base near the positioning seat. A strip-shaped opening is formed on the top wall of the base near the material storage assembly. A pushing assembly is arranged on the upper surface of the base above the strip-shaped opening. An electric telescopic rod for driving the pushing assembly is fixed to the inner top wall of the base.

[0007] Furthermore, the stamping assembly includes a lifting plate fixed to the bottom of the telescopic end of the hydraulic rod, and a punch rod is fixed on the lower surface of the lifting plate and directly above each punch hole.

[0008] Furthermore, multiple springs are fixed to the lower surface of the lifting plate, and a pressure plate is fixed to the bottom of the multiple springs. The pressure plate has multiple through holes for the punch to pass through.

[0009] Furthermore, the storage assembly includes a vertical box fixed to the upper surface of the base, with multiple vertical storage slots in the middle of the vertical box, each storage slot aligned with a positioning slot, and side holes on both sides of the bottom of each storage slot, and copper tubes stacked inside the storage slot.

[0010] Furthermore, the pushing assembly includes a slide rod slidably connected inside the strip-shaped opening, with the bottom end of the slide rod fixedly connected to the telescopic end of the electric telescopic rod. A horizontal plate is fixedly connected to the top end of the slide rod, and a plurality of push rods aligned with side holes are fixed on the surface of the horizontal plate. A push plate is fixed to one end of the push rod near the side hole.

[0011] Furthermore, a rubber sleeve is fixed to the inner wall of the positioning groove.

[0012] The beneficial effects of this utility model are:

[0013] This invention achieves continuous, fully automated copper tube stamping through an integrated linkage structure that combines material storage, automatic feeding, stamping, and finished product ejection. Specifically, multiple copper tubes to be processed are first vertically stacked in multiple storage slots of the material storage assembly. Upon startup, the electric telescopic rod drives the feeding assembly, which pushes the bottom copper tube horizontally out of the storage slot and precisely into the positioning slot at the bottom of the positioning seat through a side hole. Then, the hydraulic rod drives the stamping assembly downwards, where the stamping rod completes the stamping of the copper tube. After stamping, the stamping assembly resets, and the electric telescopic rod drives the feeding assembly again for the next cycle of feeding. At this time, the newly ejected copper tube enters the positioning slot while simultaneously pushing forward the previously formed copper tube, thus simultaneously completing the new material loading and finished product ejection. This design integrates discrete processes into a continuous mechanical flow driven by two actuators (hydraulic rod and electric telescopic rod), achieving uninterrupted continuous production.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a stamping die for copper tubes is disclosed, comprising a base 1 with a hollowed-out bottom. Multiple support rods 2 are fixed to one side of the upper surface of the base 1, and a top plate 3 is fixedly connected to the top ends of the multiple support rods 2. A hydraulic rod 4 is fixed to the upper surface of the top plate 3, and the telescopic end of the hydraulic rod 4 passes through the top plate 3 and is fixed to a stamping assembly 5. Multiple punch holes 6 are provided on the top wall of the base 1 below the stamping assembly 5. A positioning seat 7 is fixed to the upper surface of the base 1 near the punch holes 6. Multiple transverse positioning grooves 71 aligned with the punch holes 6 are provided at the bottom of the positioning seat 7. A material storage assembly 8 is fixed to the upper surface of the base 1 near the positioning seat 7. A strip-shaped opening 10 is provided on the top wall of the base 1 near the material storage assembly 8. A pushing assembly 9 is provided on the upper surface of the base 1 above the strip-shaped opening 10. An electric telescopic rod 11 for driving the pushing assembly 9 is fixed to the inner top wall of the base 1.

[0022] The stamping assembly 5 includes a lifting plate 51 fixed to the bottom of the telescopic end of the hydraulic rod 4, and a punch 52 is fixed on the lower surface of the lifting plate 51 and directly above each punch 6.

[0023] By driving the hydraulic rod 4 to extend and retract, the lifting plate 51 can be moved up and down. When the lifting plate 51 descends, it drives multiple punch rods 52 to descend, which, together with the punch holes 6 below, punch the copper tube 12 located below the punch rods 52.

[0024] Multiple springs 53 are fixed on the lower surface of the lifting plate 51, and the bottom ends of the multiple springs 53 are jointly fixed to a pressure plate 54. Multiple through holes 55 are provided on the pressure plate 54 for the punch rod 52 to pass through.

[0025] When the lifting plate 51 descends, in addition to the punching rod 52 pressing the copper tube 12, the pressure plate 54 will also flatten the part of the copper tube 12 located below the pressure plate 54 under the pressure of the spring 53, forming a terminal block.

[0026] The material storage assembly 8 includes a vertical box 81 fixed to the upper surface of the base 1. Multiple vertical storage slots 82 are formed in the center of the vertical box 81, each aligned with a positioning slot 71. Side holes 83 are formed on both sides of the bottom of each storage slot 82. Copper tubes 12 are stacked inside the storage slot 82. The height of the side holes 83 is greater than the diameter of a single copper tube 12 but less than the diameter of two copper tubes 12. Therefore, the pushing assembly 9 can only push out the bottommost copper tube 12 at a time.

[0027] The pusher assembly 9 includes a slide rod 91 that is slidably connected inside the strip opening 10, and the bottom end of the slide rod 91 is fixedly connected to the telescopic end of the electric telescopic rod 11. A horizontal plate 92 is fixedly connected to the top end of the slide rod 91. A plurality of push rods 93 aligned with the side holes 83 are fixed on the surface of the horizontal plate 92. A push plate 94 is fixed to one end of the push rod 93 near the side hole 83.

[0028] Each shortening and extension of the electric telescopic rod 11 constitutes a feeding action. When the electric telescopic rod 11 shortens, it drives the slide rod 91 and the horizontal plate 92 to move towards the vertical box 81, thereby pushing the push plate 94 at the end of the multiple push rods 93 into the side hole 83 on the side of the corresponding storage tank 82, pushing the copper tube 12 at the bottom of the corresponding storage tank 82 into the corresponding positioning groove 71. The part of the copper tube 12 passing through the positioning groove 71 is located directly below the stamping assembly 5, waiting for stamping. Then, the electric telescopic rod 11 extends, driving the pushing assembly 9 to reset, and the copper tube 12 in the storage tank 82 falls freely under gravity, ready for the next round of feeding.

[0029] A rubber sleeve is fixed to the inner wall of the positioning groove 71. When the pushing assembly 9 pushes the copper tube 12 into the positioning groove 71, the rubber sleeve can increase the friction between the inner wall of the positioning groove 71 and the copper tube 12, and prevent the copper tube 12 from sliding down when pushed by the push plate 94.

[0030] Working principle: First, multiple copper tubes 12 are stacked in each storage tank 82 of the storage assembly 8. The side hole 83 at the bottom of the storage tank 82 is designed to allow only the bottommost single copper tube 12 to be pushed out horizontally.

[0031] After startup, the electric telescopic rod 11 shortens, driving the slide rod 91 of the pushing assembly 9 to move along the strip opening 10, causing the horizontal plate 92 and its push rod 93 and push plate 94 to move towards the vertical box 81. Each push plate 94 inserts into the corresponding side hole 83, simultaneously pushing the bottom copper tube 12 of each storage tank 82 horizontally into the corresponding positioning slot 71 of the positioning seat 7. After feeding is completed, the electric telescopic rod 11 immediately extends, driving the pushing assembly 9 to reset. The remaining copper tube 12 in the storage tank 82 falls to fill the gap under the action of gravity.

[0032] At this point, the copper tube 12 is positioned, and its part to be processed aligns with the stamping assembly 5 above. The hydraulic rod 4 then extends downwards, driving the lifting plate 51 of the stamping assembly 5 to descend. The pressure plate 54 at the bottom of the lifting plate 51, under the action of the spring 53, first contacts and presses against the copper tube 12. Then, each punch 52 continues to descend, penetrating the copper tube 12 to complete the stamping process, while the pressure plate 54 partially flattens and shapes it. After stamping is completed, the hydraulic rod 4 drives the lifting plate 51, punch 52, and pressure plate 54 to rise and reset.

[0033] When the next work cycle begins, the electric telescopic rod 11 drives the pusher assembly 9 to push out a new copper tube 12. As the new copper tube 12 enters the positioning groove 71, it pushes the previous formed copper tube 12, which has already been stamped, forward out of the groove, thereby realizing automatic and continuous feeding, stamping and ejection operations.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
