[0035] The automatic production device of the perforated steel pipe of the embodiment of the utility model can not only cut the steel pipe into sections into preset lengths, but also punch and bundle the steel pipe, which greatly improves the production efficiency of steel pipe structural parts and is a significant improvement.
[0036] In addition, the automatic production equipment for perforated steel pipes can be applied to both round steel pipes and square steel pipes, and can adapt to more products.
[0037] like Figure 2As shown, on the basis of the above embodiment, in an optional embodiment of the utility model, the feeding assembly 1 includes a steel pipe placement seat 10, and a guide member 11 and a pipe pusher 12 configured on the steel pipe placement seat 10. The guide member 11 extends from the steel pipe placement seat 10 to the steel pipe feeding position of the cutting assembly 2. The pipe pusher 12 is configured to push the initial steel pipes onto the guide member 11 one by one, so that the initial steel pipes can fall into the cutting assembly 2 along the guide member 11 and can be cut into steel pipes of a preset length by the cutting assembly 2.

[0039] The feeding component 1 can supply the initial steel pipes to the cutting component 2 one by one, and a large number of steel pipes can be placed on the feeding component 1 at one time without manually feeding them one by one, which greatly releases human resources.
[0040] like Figure 3 and Figure 4 As shown, based on the above embodiments, in an optional embodiment of the utility model, the side of the first fixing portion 18 facing the first clamping member 16 is set as a plane. The first clamping member 16 is provided with the first clamping plane 17 and the first arc-shaped groove 19 on the side facing the first fixing portion 18. Wherein, the first arc-shaped groove 19 is located in the middle of the first clamping plane 17. Preferably, the number of the clamping assemblies 3 is at least four. Wherein, two clamping assemblies 3 form a pair for clamping a steel pipe. The installation directions of the two pairs of clamping assemblies 3 are opposite, and the openings of the clamping gaps of the two pairs of clamping assemblies 3 are in the same direction.
[0041] In this embodiment, the number of clamping assemblies 3 is four, and in other embodiments, it can be set to other numbers. The utility model does not specifically limit the specific number of clamping assemblies 3. Four clamping assemblies 3 are installed in parallel on a flat plate. The flat plate is used to engage with the mechanical arm 4. Two pairs of clamping assemblies 3 are respectively arranged in the width direction of the flat plate to clamp two steel pipes in parallel at the same time. When working, it is possible to first clamp the un-drilled steel pipe from the unloading place of the cutting assembly 2, and then clamp the drilled steel pipe from the drilling assembly 5, and then place the un-drilled steel pipe on the drilling assembly 5, and finally stack the drilled steel pipe on the stacking bracket 9. There is no need to move the drilled steel pipe to the stacking bracket 9 first, and then move the un-drilled steel pipe to the drilling assembly 5, which reduces the idle time of the drilling assembly 5 and greatly improves the production efficiency during work.
[0042] like Figure 5 As shown, based on the above embodiment, in an optional embodiment of the utility model, the drilling assembly 5 also includes an automatic multi-jaw chuck 23 and a rotating support 29 rotatably coupled to the drilling base 21, a third driving member 22 for driving the automatic multi-jaw chuck 23 to rotate, and a fourth driving member 28 for driving the rotating support 29 to approach or move away from the automatic multi-jaw chuck 23. Wherein, the rotating support 29 is constructed as a conical geometric body. Preferably, the automatic multi-jaw chuck 23 is an automatic three-jaw chuck. The automatic three-jaw chuck is provided with a positioning portion for supporting the end of the steel pipe.
[0043] Specifically, the fourth driving member 28 drives the rotating support member 29 to push the steel pipe onto the automatic multi-jaw chuck 23 and clamp it, and the third driving member 22 drives the automatic multi-jaw chuck 23 to rotate the steel pipe to a predetermined angle, thereby drilling holes at multiple angles of the steel pipe to accommodate steel pipes of more specifications.
[0044] like Figure 5 As shown, based on the above embodiment, in an optional embodiment of the utility model, the drilling assembly 5 further includes a drilling slide 25 configured on the drilling base 21 and movable along the axial direction of the steel pipe. The drilling machine 24 is configured on the drilling slide 25 to adjust the position of the rotary hole. The drilling assembly 5 includes two drilling machines 24, and the axis directions of the rotating shafts of the two drilling machines 24 are not parallel.
[0045] In this embodiment, the position of the drilling machine 24 in the axial direction of the steel pipe is adjusted by the drilling slide 25, so as to further improve the drilling ability of the drilling assembly 5, and the automatic multi-claw chuck 23 of the third driving member 22 rotates the steel pipe, so that drilling can be performed at any position of the steel pipe. In order to further improve the drilling ability of the drilling assembly 5, multiple drilling machines 24 are arranged to perform drilling from different angles or different positions at the same angle, which can greatly improve the drilling efficiency.
[0046] like Figure 6 As shown, based on the above embodiment, in an optional embodiment of the present invention, the baling assembly 7 is a single-head baler. The first conveying assembly 8 and the second conveying assembly are roller conveyor belts, which convey the stacking brackets 9 on both sides of the baling assembly 7 respectively.
[0047] Specifically, the steel pipes are stacked on the stacking bracket 9, and both ends extend outward. When one end of the steel pipe passes through the single-head baler, the single-head baler ties up one end of the steel pipe. After the stacking bracket 9 passes through the single-head baler, the other end of the steel pipe is in a position to cross the single-head baler, and the single-head baler ties up the other end of the steel pipe.
[0048] like Figure 7 and Figure 8 As shown, on the basis of the above embodiments, in an optional embodiment of the utility model, there are two types of stacking brackets 9, and the first type of stacking bracket 9 includes a first bracket base 32 provided with a forklift handling hole 33, and a plurality of first arms 31 extending upward from the first bracket base 32. The first arm 31 is arranged at an angle. A stacking space for stacking steel pipes is formed between the plurality of arms. Preferably, the second type of stacking bracket 9 includes a second bracket base 34, support bars 35 arranged at intervals below the first bracket base 32, a plurality of second arms 36 extending vertically upward from the first bracket base 32, and an inclined support arm 37 obliquely and detachably engaged between the support bar 35 and the second bracket base 34. Among them, a forklift handling gap is formed between the support bars 35.
[0049] Specifically, the first type of stacking bracket 9 is mainly used to stack round steel pipes. The round steel pipes are stacked into a hexagon. The second type of steel pipe can be used to stack square steel pipes when the inclined support arm 37 is removed, and can be used to stack round steel pipes when the inclined support arm is installed, which has a stronger applicability.
[0050] The direction of the support bar 35 can be arranged along the width direction of the stacking bracket 9, or along the length direction of the stacking bracket 9. When arranged along the width direction, it is more suitable for transportation on a belt conveyor. When arranged along the length direction, it is more suitable for transportation on a roller conveyor.
[0051] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
