[0001] This utility model relates to the field of stamping, and in particular to a stamping equipment for the production of safety tubes. Background Technology

[0002] The safety pipe is a key safety component in the high-pressure pipeline of automotive air conditioning. Its core function is to automatically release pressure when the system pressure rises abnormally, preventing damage to components such as the compressor, condenser, and pipelines due to high pressure, and avoiding safety hazards such as refrigerant leakage or system rupture.

[0003] Existing equipment for stamping metal round tubes generally adopts a one-time forming process. This stamping method results in a large amount of deformation of the metal round tubes, which easily leads to cracks and wrinkles, thereby reducing the production qualification rate.

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0020] This utility model provides a stamping device for the production of safety pipes, such as... Figure 1 As shown, it includes a feeding mechanism 1, four stamping dies 2, a hydraulic system 3, a truss 4, and four moving grippers 5.

[0021] Four stamping dies 2 are arranged in a row, with the stamping size of the four dies increasing sequentially from left to right, so that an initial circular tube is formed into the shape of an air conditioning safety pipe through four stamping processes. A hydraulic system 3 is equipped at the rear end of each stamping die 2 for stamping the safety pipe held inside the die 2. A truss 4 is positioned above the four stamping dies 2, and four movable grippers 5, corresponding one-to-one with each stamping die 2, are installed on the truss 4 to clamp and transport the safety pipe from the previous process to the next process. A feeding mechanism 1 is also provided on one side of the first stamping die 2, which is used to arrange the stacked safety pipes horizontally in an orderly manner for the first movable gripper 5 to clamp and feed them.

[0022] During stamping, the first moving gripper 5 clamps and transports the tube from the feeding mechanism 1 to the first stamping die 2. The first stamping die 2, in conjunction with the hydraulic system 3 behind it, performs the first stamping. Then, the second moving gripper 5 clamps and transports the tube stamped by the first stamping die 2 to the second stamping die 2. The second stamping die 2, in conjunction with the hydraulic system 3 behind it, performs the second stamping. This process is repeated until the stamping by the fourth stamping die 2 is completed. The fourth moving gripper 5 then clamps and transports the stamped safety tube off the production line.

[0023] This safety pipe stamping equipment produces safety pipe products through four stamping processes, replacing the traditional one-time stamping process. This divides the deformation amount from one step into four steps, effectively reducing cracks and wrinkles that occur during the stamping process, thus ensuring the pass rate of safety pipe production. At the same time, by controlling the deformation amount through step-by-step stamping, the pipe diameter and wall thickness tolerances are guaranteed, thereby improving the accuracy of safety pipe stamping.

[0024] In this embodiment, as Figure 4 As shown, the stamping die 2 includes a die frame 21 and two clamping dies 22. The two clamping dies 22 are both located inside the die frame 21 on both sides. An opening and closing mechanism is provided on one side of one of the clamping dies 22 to push the clamping die 22 closer to the other clamping die 22 to complete the closing / opening operation.

[0025] It can be noted that each of the four stamping dies 2 is provided with a set of clamping dies 22, and the stamping die cavities provided by the clamping dies 22 gradually increase in size from left to right.

[0026] One of the two clamping molds 22 is fixedly installed inside one side of the mold frame 21, and the other is movably installed inside the other side of the mold frame 21. The two clamping molds 22 are arranged symmetrically. The mold opening and closing mechanism drives the movably installed clamping mold 22 to move closer to or away from the fixedly installed clamping mold 22 to realize the mold closing / opening operation.

[0027] Furthermore, the mold opening and closing mechanism includes a cylinder 23, a wedge block A24, a guide rail 25, a wedge block B26, and a shaft 27. One of the clamping molds 22 is mounted on the shaft 27, and one end of the shaft 27 passes through the mold frame 21 and is connected to the wedge block B26. The cylinder 23 is mounted on one side of the mold frame 21, and its movable end is connected to the wedge block A24. The wedge block A24 is horizontally slidably mounted on the guide rail 25, and the inclined surface of the wedge block A24 is slidably mounted with the inclined surface of the wedge block B26.

[0028] It can be explained here that wedge block A24 is provided with a T-shaped protrusion, and wedge block B26 is provided with a sliding groove that matches the T-shaped protrusion, so that wedge block A24 and wedge block B26 are slidably assembled on the inclined surfaces.

[0029] When the mold is closed, the piston end of the cylinder 23 extends out and, guided by the guide rail 25, causes the wedge block A24 to move forward. Since the inclined surface of the wedge block A24 slides and mates with the inclined surface of the wedge block B26, as the thicker rear end of the advancing wedge block A24 pushes the wedge block B26 to move to the left, thereby pushing the movable clamping mold 22 to move towards the fixed clamping mold 22 through the provided shaft 27 until the two clamping molds 22 are completely fitted together.

[0030] When the mold opens, the piston end of the cylinder 23 retracts, and under the guidance of the guide rail 25, it pulls the wedge block A24 to move backward. Since the inclined surface of the wedge block A24 slides and mates with the inclined surface of the wedge block B26, as the thinner front end of the retracting wedge block A24 pulls the wedge block B26 to move to the right, the movable clamping mold 22 is pulled away from the fixed clamping mold 22 by the shaft 27 until the two clamping molds 22 are completely separated, so that the movable jaw 5 can clamp the pipe.

[0031] In this embodiment, as Figure 3 As shown, the hydraulic system 3 includes a fluid supply system 32 and a hydraulic cylinder 31. A punch head is detachably installed on the piston end of the hydraulic cylinder 31, and the punch head is aligned with the two clamping dies 22 at the front and back.

[0032] When the liquid supply system 32 works with the hydraulic cylinder 31 to extend and press, the punch head is embedded in the two clamping dies 22 to squeeze the tube inside, thereby achieving the punching process of the tube.

[0033] In this embodiment, as Figure 3 As shown, the movable gripper 5 includes a transverse module 51, a lifting module 52, and a pneumatic clamp 53. The transverse module 51 moves horizontally on the truss 4, and the lifting module is mounted on the transverse module 51 to drive the pneumatic clamp 53 assembled at its end to move up and down.

[0034] It should be noted that both the transverse module 51 and the lifting module 52 employ a rack and pinion motion module, which mainly includes a motor, motor mount, gears, rack, support components, and guide components. The principle is as follows: the rack is fixedly mounted, and the teeth of the rotating gear interact with the teeth of the fixed rack. Because the rack is fixed, the gear receives a reaction force, which, under the action of the support components and guide components, drives the motor and motor mount to move linearly along the rack. The device that needs to move is generally mounted on the motor mount. For example, in this embodiment, the lifting module is mounted on the motor mount of the transverse module, while the pneumatic clamp 53 is mounted on the motor mount of the lifting module.

[0035] In this embodiment, as Figure 4 As shown, the feeding mechanism 1 includes a hopper 11, a chain lifting belt 12, an L-shaped carrying plate 13, and a platform 14. The chain lifting belt 12 is arranged obliquely inside the hopper 11, and the end of the chain lifting belt 12 extends to the top side of the platform 14. Several carrying plates are evenly connected on the chain lifting belt 12, so that the running chain lifting belt 12 can orderly lift the individual safety tubes onto the platform 14 through the carrying plates.

[0036] The L-shaped carrier plate 13 has space to accommodate only pipes. When the chain lifting belt 12 lifts the L-shaped carrier plate 13, the pipes piled up inside the hopper 11 slide onto the L-shaped carrier plate 13 and gradually rise with the L-shaped carrier plate 13 until they reach the top and slide onto the material platform 14, thus realizing the individual and orderly arrangement of the pipes, which facilitates the gripping of the moving claw 5.

[0037] Furthermore, the feeding mechanism 1 also includes two baffles 15, a screw 16, and a guide rod 17. The two baffles 15 are vertically placed inside the hopper 11, the guide rod 17 horizontally passes through the two baffles 15 and is placed on both sides of the hopper 11, one end of the screw 16 is threadedly connected to the hopper 11, and the end of the screw 16 extends to one side of one of the baffles 15 and is rotatably connected to it.

[0038] Two baffles 15 are used to store safety tubes. One baffle 15 is fixedly installed on one side of the hopper 11 by two guide rods 17, and the other baffle 15 is slidably installed on the guide rod 17 and connected to the screw 16. A handle is provided at one end of the screw 16. Rotating the handle causes the screw 16 to rotate, thereby causing the screw 16 to move axially on the hopper 11, which in turn pushes the movable baffle 15 to move, changing the gap between the two baffles 15, and thus making adaptive adjustments according to the length of the safety tube to improve the practicality of the feeding mechanism 1.

[0039] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0040] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
