Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a steel pipe processing loading machine. Background Art

[0002] During the processing of steel pipes, processing procedures such as heating, piercing, rolling, sizing, and finishing are required. Before processing, several steel pipes need to be fed into the processing or production area. Correct loading operations can ensure production efficiency and product quality, and avoid raw material losses and production accidents.

[0003] However, when the conventional loading device feeds steel pipes, due to the limitation of the size at the limit groove, generally only steel pipes of a single specification can be conveyed. However, during the processing, the specifications of steel pipes are diverse. Especially for steel pipes of different diameters, different types of cutting equipment are required for processing, and different specifications of loading mechanisms are required for loading, resulting in a relatively high cost of the loading equipment. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a steel pipe processing loading machine to solve the problem that when loading steel pipes of different diameter specifications, different specifications of loading mechanisms are required for loading, resulting in a relatively high cost of the loading equipment.

[0005] To achieve the above object, the basic scheme of the utility model is as follows: A steel pipe processing loading machine includes a hopper and a transfer table. The hopper is in a triangular prism shape, with the rectangular end face of the hopper facing a set direction. There is a discharge port at the lower side of the hopper opposite to the upper surface of the transfer table. It further includes:

[0006] A number of transfer pipes of different specifications, which are horizontally installed on the transfer table. There is a feed port on the side wall of the transfer pipe for the steel pipe to enter, and the feed port can be aligned with the discharge port. The distance between the bottom of the inner wall of the transfer pipe and the discharge port is greater than the diameter of the steel pipe, and the distance between the bottom of the inner wall of the transfer pipe and the discharge port is less than twice the diameter of the steel pipe;

[0007] A pushing unit for pushing the steel pipe in the transfer pipe, which is horizontally arranged at one end of the transfer pipe.

[0008] The technical principle of the present utility model is as follows: When loading steel pipes, first select a transfer pipe with a suitable specification according to the specification of the steel pipe, install the transfer pipe on the transfer table so that the feed inlet on the transfer pipe is vertically aligned with the discharge outlet on the hopper; then place the steel pipes to be loaded in batches into the hopper. Under the guidance of the hopper in the shape of a triangular prism, several steel pipes are kept in a horizontal state, and the axis of the steel pipe is parallel to the axis of the transfer pipe. At this time, the lowermost steel pipe passes through the discharge outlet and enters the feed inlet, and then enters the transfer pipe; at this time, since the distance between the bottom of the inner wall of the transfer pipe and the discharge outlet is greater than the diameter of the steel pipe and less than twice the diameter of the steel pipe, the transfer pipe limits the single falling steel pipe, and the steel pipe in the transfer pipe abuts against the steel pipe in the hopper, preventing the second steel pipe from transferring into the transfer pipe or falling out through the gap between the feed inlet of the transfer pipe and the discharge outlet of the hopper, so that there is one steel pipe to be transferred remaining in the transfer pipe, which is convenient for the subsequent pusher unit to cooperate with the processing process to push the steel pipe intermittently.

[0009] When the specification of the steel pipe changes, only the transfer pipe on the transfer table needs to be replaced, which can reduce the cost required for replacing the overall structure and improve the loading replacement efficiency of steel pipes with different specifications.

[0010] Furthermore, the longitudinal section profile at the discharge outlet of the hopper is arc-shaped, and the arc at the discharge outlet is concave towards the rectangular end face of the hopper.

[0011] Through the above setting, the arc at the discharge outlet of the hopper can also limit the steel pipe during the loading process, making the limitation of the steel pipe during the transfer process more stable.

[0012] Furthermore, the central angle of the arc of the longitudinal section profile at the feed inlet of the transfer pipe is less than or equal to 180° and greater than or equal to 90°.

[0013] Through the above setting, it can ensure that the steel pipe enters the transfer pipe, and at the same time ensure that the longitudinal section profile at the feed inlet of the transfer pipe is large enough to support and position the steel pipe.

[0014] Furthermore, the end of the transfer pipe away from the pusher unit is cylindrical.

[0015] Through the above setting, when transferring the steel pipe, the cylindrical end of the transfer pipe can limit and guide the horizontal transfer of the steel pipe, making the transfer of the steel pipe more stable.

[0016] Furthermore, the pusher unit includes:

[0017] A support frame;

[0018] The pneumatic telescopic rod, one end of the pneumatic telescopic rod is fixedly connected to the support frame, the other end of the pneumatic telescopic rod faces the end of the transfer pipe, the axis of the pneumatic telescopic rod is parallel to the axis of the transfer pipe, and the pneumatic telescopic rod near the transfer pipe horizontally extends into the cylindrical end of the transfer pipe.

[0019] Through the above settings, the pneumatic telescopic rod can push the steel pipe in the transfer pipe to move horizontally under the support of the support frame, realizing the horizontal one-by-one transfer of the steel pipe. The pneumatic telescopic rod is more convenient to control the transfer timing of the steel pipe; when the end of the pneumatic telescopic rod can replace the removed steel pipe and abut against the steel pipe at the discharge port; when controlling the pneumatic telescopic rod to shorten and retract, the next steel pipe to be loaded automatically falls into the transfer pipe, and the feeding preparation for the next steel pipe can be completed.

[0020] Furthermore, an elastic push block that can penetrate into the transfer pipe is coaxially and fixedly installed at one end of the pneumatic telescopic rod near the transfer pipe.

[0021] Through the above settings, the elastic push block can be embedded at the end of the transfer pipe and stably abut against the end of the steel pipe, so that the fit between the steel pipe and the elastic push block is stable during the pushing process, and the transfer of the steel pipe is stable.

[0022] Furthermore, it further includes a switching unit, and the switching unit includes:

[0023] A rotatable conveyor belt, the conveyor belt is horizontally installed in the middle of the transfer table, and the conveying direction of the conveyor belt is perpendicular to the axis direction of the transfer pipe;

[0024] Several mounting members installed on the conveyor belt, and the mounting members are detachably connected to the side of the transfer pipe away from the hopper.

[0025] Through the above settings, when the specification of the steel pipe changes, install a transfer pipe with a suitable specification at the end of the conveyor belt, and then control the conveyor belt to move so that the transfer pipe is opposite to the discharge port of the hopper, and the replacement use of the transfer pipe can be quickly completed. The feeding replacement efficiency of steel pipes with different specifications is improved, and the feeding cost of different steel pipes is reduced. Brief Description of the Drawings

[0029] The technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] This embodiment is basically as Figure 1 and Figure 2 shown. An upper feeding machine for steel pipe processing is proposed in an embodiment of the present utility model, which includes a hopper 10, a conveying table 20, a plurality of conveying pipes 30 of different specifications, a pushing unit for pushing the steel pipes in the conveying pipe 30, and a switching unit. As Figure 1 shown, the hopper 10 is in a triangular prism shape, the rectangular end face of the hopper 10 is arranged facing, a discharge port 101 opposite to the upper surface of the conveying table 20 is provided below the hopper 10, the longitudinal section contour at the discharge port 101 of the hopper 10 is arc-shaped, and the arc at the discharge port 101 is recessed towards the rectangular end face of the hopper 10.

[0031] As Figure 1 and Figure 2 shown, the switching unit includes a rotatable conveyor belt 40 and two mounting members mounted on the conveyor belt 40. The mounting members are magnetic attraction blocks capable of magnetically attracting the conveying pipe 30. At the same time, the conveyor belt 40 is horizontally installed in the middle of the conveying table 20, the conveying direction of the conveyor belt 40 is perpendicular to the axial direction of the conveying pipe 30, and the mounting members magnetically attract the side of the conveying pipe 30 away from the hopper 10.

[0032] As Figure 1 and Figure 2 shown, the conveying pipe 30 is horizontally installed on the conveying table 20. A feeding port 301 for the steel pipe to enter is provided on the side wall of the conveying pipe 30. The feeding port 301 can be directly opposite to the discharge port 101. The end of the conveying pipe 30 away from the pushing unit is cylindrical. The distance between the bottom of the inner wall of the conveying pipe 30 and the discharge port 101 is greater than the diameter of the steel pipe, and the distance between the bottom of the inner wall of the conveying pipe 30 and the discharge port 101 is less than twice the diameter of the steel pipe. The arc central angle of the longitudinal section contour at the feeding port 301 of the conveying pipe 30 is equal to 180°.

[0033] As Figure 1 and Figure 2 shown, the pushing unit includes a support frame and a pneumatic telescopic rod 50. The right end of the pneumatic telescopic rod 50 is welded to the support frame. The left end of the pneumatic telescopic rod 50 faces the right end of the conveying pipe 30. The axis of the pneumatic telescopic rod 50 is parallel to the axis of the conveying pipe 30. The pneumatic telescopic rod 50 horizontally extends near the conveying pipe 30 to the cylindrical end of the conveying pipe 30. An elastic push block 501 that can extend into the conveying pipe 30 is coaxially fixed and glued to the left end of the pneumatic telescopic rod 50 near the conveying pipe 30.

[0034] When the steel pipe feeding machine in this embodiment is in use, first select a conveying pipe 30 with a suitable specification according to the specification of the steel pipe, connect the conveying pipe 30 to the mounting part, and then control the conveyor belt 40 to drive the corresponding conveying pipe 30 to move horizontally, so that the feeding port 301 on the conveying pipe 30 is vertically aligned with the discharging port 101 on the hopper 10; then batch place the steel pipes to be fed into the hopper 10. Under the guidance of the hopper 10 in the shape of a triangular prism, several steel pipes are kept in a horizontal state, and the axis of the steel pipe is parallel to the axis of the conveying pipe 30. At this time, the lowermost steel pipe passes through the discharging port 101 and enters the feeding port 301, and then enters the conveying pipe 30. The conveying pipe 30 limits the single falling steel pipe, and the steel pipe in the conveying pipe 30 abuts against the steel pipe in the hopper 10, preventing the second steel pipe from transferring into the conveying pipe 30 or falling out through the gap between the feeding port 301 of the conveying pipe 30 and the discharging port 101 of the hopper 10, so that there is a state of retaining one steel pipe to be conveyed in the conveying pipe 30, which is convenient for the subsequent pushing unit to cooperate with the processing procedure to push the steel pipe intermittently.

[0035] When conveying the steel pipe in the conveying pipe 30, control the pneumatic telescopic rod 50 to extend. One end of the pneumatic telescopic rod 50 close to the conveying pipe 30 pushes the elastic push block 501 to move into the conveying pipe 30 and abut against the end of the steel pipe, and then pushes the steel pipe out of the left end of the conveying pipe 30 and into the next processing procedure, realizing the feeding of the steel pipe; during this process, the end of the pneumatic telescopic rod 50 can replace the removed steel pipe and abut against the steel pipe at the discharging port 101. At the same time, the steel pipe during the removal process can be limited at the cylindrical part of the conveying pipe 30, so that the steel pipe can be stably and horizontally introduced onto the device of the processing procedure; then control the pneumatic telescopic rod 50 to shorten and retract. During this process, the next steel pipe to be fed automatically falls into the conveying pipe 30, and the feeding preparation for the next steel pipe can be completed, realizing the cycle of automatic feeding of the steel pipe and improving the single feeding efficiency of the steel pipe.

[0036] When the specification of the steel pipe changes, such as Figure 1 shown, first install a conveying pipe 30 with a suitable specification on the right side of the conveyor belt 40, and then control the conveyor belt 40 to move leftward again so that the conveying pipe 30 is opposite to the discharging port 101 of the hopper 10, and the replacement use of the conveying pipe 30 can be quickly completed, which can reduce the cost required for the replacement of the overall structure, and improve the feeding replacement efficiency of steel pipes with different specifications.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
