Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a punching device for a steel pipe rod. Background Art

[0002] Steel pipes are open at both ends and have a hollow section, and the ratio of their length to the circumference of the section is large. When the ratio of the length to the circumference of the section is small, it can be called a pipe section or a pipe fitting, both of which belong to the category of pipe fittings. Modern production is inseparable from steel pipes, and steel pipes often need to be processed when they are installed or connected to other accessories.

[0003] A Chinese patent with publication number CN219074101U discloses a punching device for steel pipe processing. Through the cooperation of a guide rail and a slider, the spacing between two sets of drilling machines is adjusted so that the distance of the spacing is the same as the hole spacing to be punched, thereby achieving multiple drilling of the steel pipe at one time; when drilling holes in different steel pipes, the connecting plate is pulled, and the connecting plate drives the two sets of first plug rods to move. When the two sets of first plug rods are no longer inserted into the slots, the clamping block is rotated. After rotating 180°, the force on the connecting plate is canceled, and the two sets of first plug rods are inserted into the slots again to complete the fixation of the clamping block.

[0004] In the above technical solution, the device places the drilling machine on the slider, and changes the position of the punching by sliding the slider on the guide rail. However, due to different requirements for steel pipes, the number of punching holes is also different. The device can only change the number of punching holes by removing the drilling machine together with the slider from the guide rail, and the process is relatively cumbersome.

[0005] Based on this, the utility model proposes a punching device for a steel pipe rod. Utility Model Content

The punching assembly makes the device more efficient and convenient.

[0007] The technical solution to achieve the purpose of the utility model is: a punching device for steel pipe rods, comprising a workbench, two support plates are fixedly connected to the workbench, two motors are fixedly connected to the two support plates, two threaded rods are fixedly connected to the output shafts of the two motors, two threaded rods are threadedly connected to the cross bars, a punching assembly is provided on the cross bar, the punching assembly comprises a sliding frame, a sliding frame, a drilling machine, a spring and a stopper, a plurality of the sliding frames are slidably connected to the cross bar, a plurality of the sliding frames are respectively slidably connected to a plurality of sliding frames, a plurality of the drilling machines are respectively fixedly connected to the sliding frames, a plurality of the stoppers are respectively slidably connected to a plurality of sliding frames, the two ends of a plurality of the springs are respectively fixedly connected to a plurality of sliding frames and a plurality of stoppers, and a positioning assembly and a fixing assembly are provided on the workbench.

[0010] Preferably, the fixing assembly comprises a slide groove and a bidirectional screw, the slide groove is opened on the workbench, and the bidirectional screw is rotatably connected in the slide groove.

[0011] Preferably, the fixing assembly also includes a lower pressure plate and a fixing rod, the two lower pressure plates are slidably connected in the slide groove, the two lower pressure plates are respectively threadedly connected to the two ends of the bidirectional screw, and the four fixing rods are respectively fixedly connected to the two lower pressure plates.

[0014] First, in the utility model, the punching assembly is fixed to the upper end or lower end of the sliding frame by the cooperation of the sliding frame, the sliding frame, the spring and the stopper. When the sliding frame is located at the lower end, the drilling machine can punch holes. When the sliding frame is located at the upper end, the drilling machine cannot punch holes because the bottom of the drilling machine is higher than the bottom of the sliding frame, thereby reducing the number of punching holes and making the device more convenient to operate.

[0025] Further, such as Figure 1-Figure 3 As shown, the positioning assembly 7 includes a connecting plate 71, a pointer 72, a scale 73 and a telescopic rod 77. The multiple telescopic rods 77 are respectively fixedly connected to the multiple sliding frames 61, and the multiple connecting plates 71 are respectively fixedly connected to the multiple telescopic rods 77. The cross-section of the connecting plate 71 is "L" shaped, and the multiple pointers 72 are respectively fixedly connected to the multiple connecting plates 71. The scale 73 is arranged on the workbench 1.

[0026] Further, such as Figure 1 and Figure 2 As shown, the positioning assembly 7 also includes a limit slot 74, a slide rod 75 and a limit column 76. A plurality of limit slots 74 are opened on the workbench 1. A plurality of slide rods 75 are respectively slidably connected to a plurality of connecting plates 71. A plurality of limit columns 76 are respectively fixedly connected to a plurality of slide rods 75. The diameter of the limit column 76 is slightly smaller than the diameter of the limit slot 74.

[0027] Further, such as Figure 1 and Figure 2 As shown, the fixing assembly 8 includes a slide groove 81 and a bidirectional screw 82 . The slide groove 81 is opened on the workbench 1 .

At this time, the sliding frame 62 can be pushed up. When the sliding frame 62 moves up, it will push the uppermost stopper 65 to embed into the sliding frame 61. When the bottom of the sliding frame 62 is higher than the stopper 65 When the position of the punching hole needs to be adjusted, the slide bar 75 is moved upward so that the limit column 76 is disengaged from the limit groove 74. At this time, the connecting plate 71 is no longer fixed. The connecting plate 71 can be pushed according to the cooperation of the scale 73 and the pointer 72 so that the corresponding pointer 72 reaches the appropriate position. The sliding frame 61 moves along with the telescopic rod 77, thereby changing the position of the punching hole. After adjusting to the appropriate position, the slide bar 75 is pushed downward so that the limit column 76 is embedded in the limit groove 74, that is, the fixation is completed, and the motor 3 and the drill 63 can be started to start punching holes in the steel pipe rod.
