[0002] In the processing of finished metal pipes, double-sided punching is also one of the processing technologies. The newly manufactured metal pipes need to be punched at both ends according to specific usage requirements.

[0003] There are many types of punching devices on the market, but most of them cannot punch holes on both ends of metal pipes one by one and in an orderly manner, which makes the overall punching efficiency low. In addition, during the punching process, when loading metal pipes, most of them use a loading cylinder to drive the push block to lift the metal pipe to the top surface of the baffle frame before unloading. Although this can also complete the loading of metal pipes, the metal pipes are prone to shaking during the loading process, resulting in an unstable loading process. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a double-sided punching device for metal pipes to solve the problems of low punching efficiency and unstable feeding process of existing double-sided punching devices for metal pipes.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0016] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0017] Combination Figure 1-3As shown, the double-sided punching device for metal pipes includes a machine platform 1, on which a pair of left and right bases 2 are provided, a blanking trough 3 is provided on the inner side of the base 2, a guide seat 4 is provided on the base 2 corresponding to the blanking trough, a puncher 5 is provided on the base 2 and facing the front and rear positions of the guide seat, and the drill bit of the puncher 5 penetrates into the guide seat 4, and a loading mechanism is provided on the front side of the two bases 2, and the loading mechanism includes a loading rack 6 respectively installed on the two bases, and a stopper 7 is provided on the inner side and the end of each loading rack 6, and a push block 8 is slidably provided on the front wall of the stopper 7, and a short column 9 is provided on the side wall of the push block 8, and a loading cylinder 10 is also provided on the base 2, and a driving shaft of the loading cylinder 10 is provided with a pusher 11 and the pusher is arranged adjacent to the stopper 7, and a forward and upward inclined slot 12 is provided on the pusher 11, and the short column 9 is located in the inclined slot 12. A blanking rack 13 is provided on the inner side of the base 2 corresponding to the blanking trough 3 and facing backward.

[0018] After the metal pipe fittings are produced according to the requirements, in order to meet some specific use requirements, it is necessary to use this device to punch holes at the ends of both sides of the metal pipe fittings.

[0019] When the device is used to punch holes in batches of metal pipe fittings, the metal pipe fittings are first placed on the feeding mechanism as required, and the metal pipe fittings are fed into the two guide seats one by one and in an orderly manner through the feeding mechanism. After the two ends of the metal pipe fittings are clamped, a pair of punchers located on the left and right bases respectively move toward the ends of the metal pipe fittings and punch holes. When the punching is completed, the two pairs of punchers are reset, and the metal pipe fittings fall from the blanking chute to the blanking rack for unloading.

[0020] When the feeding mechanism is used to feed the metal pipe fittings one by one and in an orderly manner, the two ends of the lowest metal pipe fitting on the feeding rack are respectively located on the two pushing blocks, and the two feeding cylinders simultaneously drive the corresponding pushing rack to move toward the guide seat. Since the short column is installed on the inclined groove on the pushing rack, the pushing rack moves toward the guide seat, and the pushing block will move upward. The metal pipe fitting moves along the height direction of the baffle frame under the pushing of the pushing block, and the top surface of the baffle frame is a backward slope. When the metal pipe fitting is pushed to the top surface of the baffle frame, the metal pipe fitting will roll into the two guide seats and fall on the two receiving plates.

[0021] And as Figure 3 A clamping cylinder 14 is provided on the outer wall of each guide seat 4 , and a driving shaft of the clamping cylinder 14 passes through the guide seat 4 and is provided with a clamping column 15 .

[0022] When the metal pipe falls on the two receiving plates, the pipe openings on both sides of the metal pipe correspond to the clamping columns on the same side. Then, the two clamping cylinders simultaneously drive their respective clamping columns to clamp the metal pipe. After the metal pipe is clamped, the push frame is reset under the drive of the loading cylinder, and the push block is reset. The next metal pipe slides onto the two push blocks and is ready for loading. In this process, two pairs of punching machines punch holes on the ends of both sides of the metal pipe at the same time. After the punching is completed, all the punching machines are reset, and the clamping cylinder drives the clamping column to reset. The metal pipe falls from the blanking chute to the unloading rack for unloading. The entire punching process of the metal pipe is relatively continuous, which makes the device more efficient in punching metal pipes.

[0023] As a preferred structure, the blocking frame 7 is provided with a guide hole 16, and the pushing frame 11 is provided with a guide rod 17, and the guide rod 17 penetrates the guide hole 16. When the feeding cylinder drives the pushing frame to move forward and backward, the guide rod also moves forward and backward and is always located in the guide hole. In this way, it can play a guiding role, making the pushing frame more stable during the forward and backward movement.

[0024] like Figure 1 In this structure, a pair of slide bars 18 are provided on the machine 1, wherein the left base is fixedly mounted on the slide bar, and the right base is slidably mounted on the slide bar through a slide seat (blocked in the figure). A screw rod 19 is rotatably provided on the machine 1, and a screw rod sleeve is sleeved on the screw rod 19, and the screw rod sleeve is connected to the slide seat. The machine 1 is also provided with a driving motor 20 for driving the screw rod 19 to rotate.

[0025] In this structure, the distance between the two bases can be adjusted according to the different lengths of metal pipes, so that holes can be punched on both ends of metal pipes of different lengths, thereby improving the applicability of the device. When adjustment is required, the drive motor drives the screw rod to rotate, and the screw rod sleeve moves along the length direction of the screw rod. Driven by the slide seat, the right base moves along the length direction of the slide rod until the adjustment is completed.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
