[0040] In order to make the technical means, the creation features, the purposes and the effects realized by the utility model easy to understand, the technical scheme of the utility model will be further explained in detail below in combination with the drawings and the specific embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0041] Embodiment 1: the actual use process steps of the pipe feeding mechanism for the automatic welding production of the structural pipe core material plate are as follows:

[0042] After the metal plate 1 enters the welding station, the pipe inserting and welding mechanism is also horizontally moved to the position, is aligned with the through hole on the metal plate 1, and is ready for pipe inserting and welding. At this time, the push head of the telescopic push rod cylinder for controlling discharging on the pipe inserting and welding mechanism is in contact with the push plate 746 and is aligned, and waits for pipe inserting.

[0043] The metal pipes 2 are vertically stacked in the open-top pipe storage bin 71, and the discharging passage 72 at the bottom of the pipe storage bin 71 is sized to match the length and diameter of the metal pipes 2, so that the metal pipes 2 can orderly enter the discharging passage 72.

[0044] The hanging lug-type chute 714 on both sides of the pipe storage bin 71 is installed on the transverse slide rail 35 on both sides of the gantry 31, and is connected to the first pipe storage bin 71 through the transverse driving device 36 such as a motor or a pneumatic cylinder at one end of the gantry 31, so as to adjust the position of the pipe storage bin 71. If the capacity of the pipe storage bin 71 needs to be increased, a plurality of pipe storage bins 71 can be installed in series through the linkage component 37 at both ends of the top of the pipe storage bin 71.

[0045] The discharging passage 72 and the discharging port 73 are connected and installed through the connecting plate 76, so that one discharging passage 72 corresponds to one discharging port 73, and the limiting installation plate 712 is installed below the outlet at the bottom of the pipe storage bin 71 for installing the linkage valve mechanism.

[0046] Under normal circumstances, the push plate 746 of the push rod component 74 is in the initial position under the action of the return spring 748, and the pushing plate 75 is close to the inner wall of the side plate of the limiting installation plate 712. At this time, the limiting installation plate 712 receives and limits one metal pipe 2 falling out of the discharging passage 72, and the main metal pipe 2 limits the next metal pipe 2 from falling into the limiting installation plate 712. The metal pipes 2 in the pipe storage bin 71 are orderly rolled into the discharging passage 72 under the action of gravity and the guide of the bottom inclined surface structure.

[0047] When the pipe inserting and welding mechanism receives a control instruction, the telescopic push rod cylinder performs a push rod movement to push the push plate 746 to compress the spring. After the push plate 746 is subjected to a longitudinal thrust, the return spring 748 is compressed, and the L-shaped folding slide plate of the push rod component 74 is driven to move longitudinally along the waist-shaped slide groove 742.

[0048] During the longitudinal displacement of the push rod component 74, the pin 745 is obliquely slid in the oblique groove 744 and drives the pushing plate 75 to move laterally along the transverse groove 713 due to the combined action of the transverse groove 713 on the bottom plate of the limiting installation plate 712, the oblique groove 744 below the L-shaped folding slide plate, and the pin 745.

[0049] The pushing plate 75 pushes the metal pipe 2 on the limiting installation plate 712 to be pushed out laterally, and the metal pipe 2 rolls and slides out of the lateral gap between the limiting installation plate 712 and the discharging passage 72, completing a feeding action and delivering the metal pipe 2 to the pipe inserting and welding mechanism for pushing the metal pipe 2 into the through hole of the metal plate 1 for welding operation.

[0050] After the insertion and welding of the metal pipe 2 by the insertion and welding mechanism and the reset, the push rod of the telescopic push rod cylinder is retracted, the push plate 746 of the push rod part 74 loses the pushing force and is reset along the waist-shaped sliding groove 742 under the action of the reset spring 748, and the push plate 75 is also returned to the initial position.

[0051] After the reset of the push plate 75, the next metal pipe 2 falls on the limiting installation plate 712 from the feeding channel 72 and waits for the next feeding instruction, and the cycle is repeated to continuously provide the metal pipe 2 for the insertion and welding mechanism.

[0052] In the above process, the transverse driving device 36 controls the feeding of the pipe feeding mechanism to match the transverse movement of the insertion and welding mechanism, so that it can cover the transverse movement range of the insertion and welding mechanism and feed in the range. Of course, this is only applicable to the case where the coverage range of a single insertion and welding mechanism is greater than that of one pipe storage bin 71. If the coverage range of the pipe storage bin 71 can meet the transverse movement range of the insertion and welding mechanism, the transverse driving device 36 can not be configured.

[0053] Finally, it should be noted that the above has clearly and completely described the concept, specific structure and generated technical effects of the utility model with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the utility model. In addition, all the coupling and connection relationships mentioned in the text do not mean that the components are directly connected, but that a better coupling structure can be composed by adding or reducing coupling auxiliary components according to the specific implementation situation. The various technical features in the utility model creation can be interactively combined without mutual contradiction and conflict.
