[0038] Please refer to Figures 1 to 6 as shown, which shows the specific structure of the preferred embodiment of the present utility model, including a base 10, an upper cover 20, a mandrel 30, a material pushing component 40, a supporting component 50, a positioning component 60 and a punching component 70.

[0039] The upper cover 20 is arranged on the base 10 so as to be movable up and down under the drive of an external drive mechanism; in this embodiment, a pressing plate 21 is arranged on the upper cover 20, and the pressing plate 21 is arranged directly above the mandrel 30 so as to be movable up and down along with the upper cover 20. The pressing plate 21 is used to press the round tube on the mandrel 30 to prevent the round tube from sliding relative to the mandrel 30 during the punching process, ensuring the accuracy of the punching position.

[0040] The mandrel 30 extends horizontally and is suspended above the upper surface of the base 10, and one end of the mandrel 30 is fixed to the base 10. A plurality of punching holes 301 are recessed in the mandrel 30 at intervals; in this embodiment, a guiding portion 31 is provided at the outer end of the mandrel 30, and the guiding portion 31 is used to facilitate the round tube to be sleeved on the mandrel 30 from the outer end. A waste material groove 302 communicating with the punching holes 301 is formed in the mandrel 30, and the waste material groove 302 penetrates through the lower end surface of the mandrel 30; the waste material groove 302 is used to discharge the waste material formed at the punching opening from the mandrel 30.

[0041] The pushing component 40 is arranged on the base 10 and located at the fixed end of the mandrel 30. The pushing component 40 is used to push the punched round tube off the mandrel 30, facilitating the removal process of the round tube. In this embodiment, the pushing component 40 includes a pushing rod 41 and a pushing driving mechanism 42. There are two pushing rods 41, which are respectively arranged on the base 10 and on both lateral sides of the mandrel 30.

The pushing driving mechanism 42 is arranged on the base 10 and drives the pushing rod 41 to move back and forth. Through the movement of the pushing rod 41, the punched round tube is pushed off the mandrel 30.

[0042] The supporting component 50 is arranged on the base 10 to move back and forth and is located below the other end of the mandrel 30. The supporting component 50 is used to support the suspended end of the mandrel 30, thus playing a supporting role for the suspended end of the mandrel 30 to prevent it from being bent downward due to a downward force. In this embodiment, the supporting component 50 includes a supporting plate 51 and a supporting driving mechanism 52. The supporting plate 51 is arranged on the base 10 to be able to move back and forth and is located below the outer end of the mandrel 30. The supporting driving mechanism 52 is arranged on the base 10 and drives the supporting plate 51 to move back and forth. Through the supporting driving mechanism 52, the supporting plate 51 is moved to the position below the outer end of the mandrel 30, so that the outer end of the mandrel 30 falls on the supporting plate 51, avoiding the suspension of the mandrel 30 during the punching process and resulting in the deformation of the mandrel 30.

[0043] The positioning component 60 is arranged on the base 10 and is located beside the mandrel 30. In this embodiment, the positioning component 60 includes a first mounting base 61, a first sliding seat 62, a positioning head 63 and a mounting plate 64. The first mounting base 61 is arranged on the base 10 and is located beside the mandrel 30. The first sliding seat 62 is matched with the first mounting base 61 and is arranged to slide back and forth on the first mounting base 61. The positioning head 63 is arranged on the first sliding seat 62 and moves back and forth beside the mandrel 30 along with the first sliding seat 62. The mounting plate 64 is arranged on the upper cover 20 and moves back and forth along with the upper cover 20. The mounting plate 64 is matched with the first sliding seat 62 and drives the first sliding seat 62 to slide back and forth. When loading the round tube, the position of the round tube is positioned by the positioning head 63, further ensuring the accuracy of the punching position.

[0044] The punching assemblies 70 are provided in plurality, and the plurality of punching assemblies 70 are all arranged on the base 10 and beside the mandrel 30, and each punching assembly 70 corresponds to the position of the corresponding punching hole 301; in this embodiment, the punching assembly 70 includes a second mounting seat 71, a second sliding seat 72, a punch 73, a movable rod 74 and a spring 75; the second mounting seat 71 is arranged on the base 10 and beside the mandrel 30, and an obliquely extending chute 701 is arranged on the second mounting seat 71; the second sliding seat 72 is arranged in the chute 701 and slides back and forth along the chute 701, and a first guiding surface 721 arranged obliquely is arranged on the second sliding seat 72; the punch 73 is arranged on the second sliding seat 72 and moves back and forth beside the punching hole 301 along with the second sliding seat 72; the movable rod 74 is arranged on the upper cover 20 and moves up and down along with the upper cover 20, the movable rod 74 corresponds to the position of the second sliding seat 72, and a second guiding surface 741 matched with the first guiding surface 721 is arranged on the movable rod 74; one end of the spring 75 is arranged at the outer end of the second sliding seat 72, the other end of the spring 75 is arranged on the second mounting seat 71, and the spring 75 is used for urging the second sliding seat 72 to reset and pulling out the punch 73 from the punching hole 301 through the second sliding seat 72.

[0045] The working principle of this embodiment is described in detail as follows:

[0046] During working, first, the external driving mechanism drives the upper cover 20 to move upward, and at the same time, the supporting driving mechanism 52 drives the supporting plate 51 away from the outer end of the mandrel 30. Then, an operator sleeves the to-be-processed round tube on the mandrel 30 through the guiding portion 31. At the same time, the positioning head 63 in the positioning assembly 60 moves towards the mandrel 30 under the drive of the upper cover 20 and positions the round tube on the mandrel 30. At the same time, the pressing plate 21 on the upper cover 30 presses the round tube, and the supporting driving mechanism 52 drives the supporting plate 51 to move to the lower part of the outer end of the mandrel 30 and support the mandrel 30. Then, the punching assembly 70 completes the punching process of the round tube. After punching is completed, the supporting driving mechanism 52 drives the supporting plate 51 away from the mandrel 30, and the round tube is pushed outwards through the push rod 41 in the pushing assembly 40, and the operator can take down the pushed-out round tube.

[0047] The design focus of the present utility model lies in: by providing a material pushing component and a supporting component, and the material pushing component is arranged on the base and located at the fixed end of the mandrel. After the punching is completed, the round tube is pushed outwards from the fixed end of the mandrel by the material pushing component, facilitating the removal process of the round tube after punching. At the same time, the supporting component is arranged on the base in a reciprocating manner and located below the other end of the mandrel. The supporting component is used to support the suspended end of the mandrel. When loading materials, the supporting component moves to the side of the mandrel. When punching is carried out, the supporting component moves below the mandrel and supports the suspended end of the mandrel, thereby playing a supporting role for the mandrel and avoiding deformation due to the pressing force and the impact force of the punching process, effectively increasing the service life of the punching device.

[0048] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
