Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a metal pipe punching machine. Background Art

[0002] Metal pipes are widely used in daily life and industrial production. Generally, when installing and using metal pipes, holes need to be punched on the circumferential surface so that the metal pipes can be connected and fixed to other workpieces.

[0003] Existing punching technology mostly uses machines to punch holes in metal tubes. During the punching process of metal tubes and other tubular objects, the metal tubes are difficult to fix due to their cylindrical shape, and most of the existing punching machines have relatively complex structures, resulting in many movements in the punching process. The punching needle is subjected to force and shakes during the punching process, which easily results in rough holes, unqualified hole shapes, and inaccurate positioning, resulting in low punching efficiency and pass rate. Utility Model Content

[0005] According to the utility model, a metal pipe punching machine includes a frame, a linear guide rail arranged on the bottom wall of the frame, and a driving assembly arranged on the frame. Two symmetrically arranged clamping members are slidably provided on the linear guide rail. Punching assemblies are slidably provided on the opposite side walls of the two clamping members along the vertical direction. Positioning blocks corresponding to the punching assemblies are provided at the bottoms of the opposite side walls of the clamping members. The punching assembly is used to cooperate with the positioning blocks to perform a punching operation on the metal pipe.

[0006] The driving assembly includes a pressing frame slidably arranged between the two clamping members, the pressing frame having a connecting portion, the connecting portion being formed with a through slot for the punching assembly to move laterally, and a guide portion being formed at the corresponding side walls of the pressing frame and the two clamping members, the guide portion being formed by the connecting portion having a lateral length that gradually decreases upward in the vertical direction;

[0007] The two clamping members are provided with small brackets at the corresponding positions of the guide part, and the small brackets are used to slide in contact with the guide part so as to enable the clamping members to adjust the spacing and guide the punching assembly to move up and down under the drive of the pressing frame.

[0008] Preferably, the driving assembly further comprises a cylinder and a connecting piece provided at the top wall of the frame, and the pressing frame is fixedly provided at the telescopic end of the cylinder via the connecting piece.

[0009] Through the above structure, the extension and retraction distance and speed can be accurately controlled, thereby achieving accurate control of the position of the pressing frame and the applied pressure.

[0010] Preferably, the clamping member has a slide plate at one end away from the positioning block, the slide plate is fixed at the moving end of the linear guide rail, and tension springs are fixed between adjacent slide plates, which are used to provide elastic force to keep the two clamping members always in a direction toward each other.

[0011] Through the above structure, the two clamping members are always in a tendency to face each other, so that the small bracket is always in close contact with the guide part.

[0012] Preferably, a pulley that contacts the guide portion is rotatably provided at a position corresponding to the small bracket and the guide portion.

[0013] Through the above structure, the pulley can ensure that the small bracket slides smoothly on the guide part, reducing the bumps and vibrations caused by uneven friction or uneven guide part, and improving the stability and reliability of the entire punching process.

It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0022] Example 1

[0023] See also Figure 1-3 This embodiment provides a metal pipe punching machine, which includes a frame 100, a linear guide rail 110 provided on the bottom wall of the frame 100, and a driving assembly provided on the frame 100. Two symmetrically arranged clamping members are slidably provided on the linear guide rail 110. Punching assemblies are slidably provided on the opposite side walls of the two clamping members along the vertical direction. Positioning blocks 120 corresponding to the punching assemblies are provided at the bottom of the opposite side walls of the clamping members. The punching assembly is used to cooperate with the positioning blocks 120 to perform a punching operation on the metal pipe.

[0024] The driving assembly includes a pressing frame 130 slidably disposed between the two clamping members. The pressing frame 130 has a connecting portion formed with a through slot for the punching assembly to move laterally. The pressing frame 130 and the two clamping members have guide portions formed at corresponding side walls. The guide portions are formed by the connecting portion having a lateral length that gradually decreases upward in the vertical direction.

[0025] The two clamping members are provided with small brackets 210 at the corresponding positions of the guide part. The small brackets 210 are used to slide in contact with the guide part so that the clamping members can adjust the spacing and guide the punching assembly to move up and down under the drive of the pressing frame 130.

[0026] When the present invention is in use, the two ends of the metal tube are sleeved on the corresponding positioning blocks 120, and the cylinder 220 drives the pressure frame 130 connected to the connecting piece 230 to move downward, and at the same time drives the slide 310 to move on the linear guide 110 through the small bracket 210, and the clamping piece connected to the slide 310 prompts the corresponding positioning block 110 to push the metal tube inward at the same time, playing a role of positioning restriction. When the small bracket 210 reaches the lateral limit position, the pressure frame 130 is driven by the cylinder 220 to continue to push the punch needle mounting seat 320 to drive the punch needle 330 to impact the metal tube downward to form a punching hole, and then under the action of the driving force of the cylinder 220, the mechanical linkage drives the punch needle 330 to withdraw upward, the two positioning blocks 110 open outward, and the punching of the metal tube is completed.

[0027] Compared with the prior art, the present invention only uses one cylinder as the power source, and the structure and movement are simple.

[0030] In this embodiment, the clamping member has a slide 310 at one end away from the positioning block 120. The slide 310 is fixed at the moving end of the linear guide rail 110. A tension spring is fixed between adjacent slides 310 to provide elastic force to keep the two clamping members always in a direction toward each other.

[0031] Through the above structure, the two clamping members are always in a direction toward each other, so that the small bracket 210 is always in close contact with the guide part.

[0032] In this embodiment, a pulley that contacts the guide portion is rotatably provided at a position of the small bracket 210 corresponding to the guide portion.

[0033] Through the above structure, the pulley can ensure that the small bracket 210 slides smoothly on the guide part, reducing the bumps and vibrations caused by uneven friction or uneven guide part, and improving the stability and reliability of the entire punching process.

[0034] In this embodiment, the punching assembly includes a punch needle mounting seat 320 slidably arranged on the side wall of the clamping member, and a punch needle 330 is provided at the corresponding end of the punch needle mounting seat 320 and the positioning block 120.
