Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe processing equipment, and particularly relates to a stainless steel pipe cold rolling processing device. BACKGROUND

[0002] Before cold rolling processing, a stainless steel pipe needs to be sequentially fed into a cold rolling device for processing. The feeding stability of the steel pipe when entering the cold rolling device directly affects the continuity of the cold rolling process and the quality of the finished product. In the prior art, the steel pipe is usually rolled on an inclined conveying table by gravity or is fed into the cold rolling device by cooperating with a driving conveying structure.

[0003] However, in the feeding mode of only relying on gravity rolling or a simple blocking structure, the steel pipe lacks a clear rhythm control mechanism before entering the cold rolling device, and multiple steel pipes may enter the feeding area at the same time, thereby causing stacking or mutual interference at the entrance of the cold rolling device, affecting the orderly feeding of the steel pipe. To avoid this problem, the prior art often needs to set multiple independent driving mechanisms to control the blocking and feeding actions of the steel pipe, which not only increases the structural complexity, but also easily causes the problem of asynchronous action in the process of multiple driving cooperation, and it is difficult to ensure that the steel pipe can enter the cold rolling device continuously and stably, one by one. Therefore, we propose a stainless steel pipe cold rolling processing device. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a stainless steel pipe cold rolling processing device, which overcomes the deficiencies of the prior art, is reasonable in design, compact in structure, and solves the problems raised in the background art.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme:

[0006] A stainless steel pipe cold rolling processing device, characterized in that it comprises:

[0007] a table top arranged obliquely and used for carrying the steel pipe and enabling the steel pipe to roll along the longitudinal direction by gravity;

[0008] a steel pipe limiting mechanism arranged at the head of the table top and used for controlling the release of the steel pipe one by one after being unpacked in bundles;

[0009] a steel pipe blocking mechanism arranged at the tail of the table top and used for temporarily blocking or releasing the steel pipe which is released from the steel pipe limiting mechanism and rolls down along the table top;

[0010] a feeding mechanism arranged at the tail of the table top and located downstream of the steel pipe blocking mechanism, and used for receiving the released steel pipe and lifting and conveying it to the entrance of the cold rolling device;

[0011] The driving mechanism is in transmission connection with the steel pipe blocking mechanism and the feeding mechanism respectively, so that the driving mechanism synchronously completes the blocking and releasing of the steel pipe and the lifting and feeding action in one driving process, thereby making the steel pipe enter the cold rolling equipment one by one and orderly.

[0012] Preferably, the steel pipe limiting mechanism comprises a limiting rod provided rotatably at the head of the table top and a limiting cylinder for driving the limiting rod to rotate, and the limiting rod selectively abuts against or is separated from the surface of the table top under the driving of the limiting cylinder, so as to release the steel pipe one by one.

[0013] Preferably, the limiting rod is rotatably connected to the head extension rod provided at the head of the table top through a connecting shaft, and the connecting shaft is fixedly connected with a rod connecting plate and a driven plate.

[0015] Preferably, the steel pipe blocking mechanism comprises a fixed rod fixedly provided at the tail of the table top, a rotating rod rotatably provided around the fixed rod, and a blocking cylinder for driving the rotating rod to deflect around the fixed rod.

[0016] Preferably, one side of the rotating rod is connected with the fixed rod through a first rotating shaft, and the other side of the rotating rod is connected with a blocking connecting rod through a second rotating shaft, and the blocking connecting rod is connected with the output end of the blocking cylinder.

[0017] Preferably, the feeding mechanism comprises a connecting block fixedly connected at the tail of the table top, a connecting shaft vertically provided and penetrating through the connecting block, and an extension plate fixedly connected at the top end of the connecting shaft, and the distal end of the extension plate is provided with a limiting column for receiving the steel pipe.

[0018] Preferably, a power rod is rotatably provided on the connecting shaft, and the tail of the table top is provided with a feeding rotating shaft rotatably provided around the shaft body, and the outer edge of the feeding rotating shaft is fixedly connected with a feeding guide rod and a feeding rotating plate.

[0019] Preferably, the feeding rotating plate is hingedly connected with the power rod through a transmission rod, and the power rod is hingedly connected with the blocking connecting rod, so that the blocking cylinder drives the rotating rod to deflect and simultaneously drives the feeding rotating shaft to rotate.

[0020] Preferably, a plurality of head extension rods and tail extension rods are provided at intervals along the transverse direction on the table top, and mounting gaps are formed between adjacent extension rods, and the head extension rod is provided with a concave surface matched with the outer wall of the bundled steel pipe, and the tail extension rod is provided with a mounting plate, and the blocking cylinder is mounted on the mounting plate.

[0021] The present application provides a stainless steel pipe cold rolling processing device.

[0022] 1. The application realizes the controllability of the steel pipe feeding rhythm from the source, avoids multiple steel pipes entering the subsequent mechanism at the same time, and improves the continuity and stability of the overall feeding process by setting a rotatable steel pipe limiting mechanism at the head of the inclined table top, and selectively lifting or resisting the limiting stop rod relative to the table top by a limiting cylinder, so that the bundled and disassembled steel pipes change from a continuous stacking state to a controllable single release state under the action of gravity.

[0023] 2. The application sets a steel pipe blocking mechanism driven by a blocking cylinder in the middle of the steel pipe rolling path, controls the temporary storage and flow separation of downstream steel pipes by deflecting the rotating rod around the fixed rod, so that the steel pipes released by the limiting mechanism are subjected to secondary rhythm adjustment before entering the feeding station, effectively weakening the concentrated falling trend of the steel pipes when relying on gravity to roll down, and reducing the mutual collision and attitude instability between the steel pipes.

[0024] 3. The application sets a rotatable feeding mechanism, uses the limiting column to position the steel pipe, and through the lifting action of the feeding guide rod, guides the steel pipe from the rolling state to the pulley in the cold rolling push rod groove, so that the steel pipe completes the conversion of attitude and height before entering the cold rolling equipment, realizes the smooth transition of the steel pipe from passive gravity transportation to active cold rolling feeding, and improves the position consistency of the steel pipe entering the cold rolling equipment.

[0025] 4. The application connects the blocking mechanism and the feeding mechanism in structure, so that the single driving action of the blocking cylinder completes the release, receiving and lifting of the steel pipe, and the steel pipe completes the continuous action of blocking-receiving-feeding in the order according to the predetermined sequence in time and space, so as to realize the purpose of the steel pipe entering the cold rolling equipment in a single rhythm without adding additional driving source, the overall structure is simplified and the action coordination is strong, and the reliability of the cold rolling feeding system is significantly improved.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, what is described is part of the present application, not the whole. Based on the present application, all other obtained by those skilled in the art without creative labor shall fall within the protection scope of the present application.

[0036] Referring to the drawings Figures 1-8 A stainless steel pipe cold rolling device, the present application provides a stainless steel pipe cold rolling device, which comprises a tabletop 1 arranged obliquely, used for bearing and guiding the longitudinal rolling conveying of the stainless steel pipe.

[0037] A plurality of head extension rods 11 are arranged at the highest part of the tabletop 1 along the transverse direction thereof, and installation gaps for mounting the steel pipe limiting mechanism 2 are formed between adjacent head extension rods 11. A concave surface 12 is formed on each head extension rod 11, which is used for cooperating with the convex surface of the bundled steel pipe outer wall, so as to form preliminary positioning and limiting for the bundled steel pipe.

[0038] The steel pipe limiting mechanism 2 comprises a connecting shaft 21 rotatably connected to the side of the head extension rod 11, and the connecting shaft 21 is fixedly connected with a stop rod connecting plate 22 and a driven plate 24. The top of the stop rod connecting plate 22 is fixedly connected with a limiting stop rod 23, which extends from the stop rod connecting plate 22 to the lower side of the tabletop 1, and the extending end thereof abuts against the upper surface of the tabletop 1, used for forming blocking for the steel pipe located at the highest part of the tabletop 1.

[0039] A cylinder mounting base 27 is also fixedly installed on the desktop 1. A limit cylinder 26 is installed on the cylinder mounting base 27. The output end of the limit cylinder 26 is hinged to a drive rod 25. The other end of the drive rod 25 is fixedly connected to the driven plate 24.

[0040] See attached document Figure 4 When the limiting cylinder 26 retracts, it drives the driven plate 24 to rotate clockwise around the connecting shaft 21 via the driving rod 25. This causes the stop connecting plate 22 and the limiting stop 23 to rotate clockwise simultaneously, causing the extension end of the limiting stop 23 to detach from the surface of the table 1. Its height is slightly greater than the diameter of the steel pipe section, which can be set according to the specific situation or the diameter of the steel pipe section, thus removing the obstruction to the steel pipe. At this time, the unbundled steel pipes can roll down the table 1 one by one under their own weight, realizing the release of individual steel pipes.

[0041] The tail of the desktop 1 is connected to multiple tail extension rods 13, and a mounting plate 14 is fixedly connected to one of the tail extension rods 13. A mounting groove is formed between adjacent tail extension rods 13, and a steel pipe blocking mechanism 3 and a feeding mechanism 4 are arranged in the mounting groove.

[0042] The steel pipe blocking mechanism 3 includes a fixed rod 31 that passes through and is fixedly connected to the tail extension rod 13. A first rotating shaft 32 is rotatably connected to the fixed rod 31. A rotating rod 33 that can deflect along the rolling direction of the steel pipe is connected to one side of the first rotating shaft 32, and a second rotating shaft 34 is connected to the other side of the rotating rod 33. Multiple second rotating shafts 34 are connected to the same blocking link 35. A blocking cylinder 36 is connected to the mounting plate 14, and the output end of the blocking cylinder 36 is connected to the end of the blocking link 35. When the blocking cylinder 36 is activated, the rotating rod 33 can be driven to deflect around the first rotating shaft 32 through the blocking link 35, thereby selectively blocking or allowing the steel pipe to pass, so as to prevent multiple steel pipes from falling at the same time.

[0043] The feeding mechanism 4 in the installation slot includes a connecting block 41 fixedly connected to the tail extension rod 13. A connecting shaft 42 is vertically connected to the connecting block 41. The connecting shaft 42 passes through the connecting block 41 and is fixedly connected to the top of the shaft. An extension plate 43 is fixedly connected to the top end of the extension plate 43. An upwardly extending limiting post 44 is connected to the far end of the extension plate 43 for receiving and limiting the steel pipe that rolls to the tail.

[0044] A shaft is provided at the end of the tail extension rod 13, and the feeding shaft 45 is rotatably connected to the tail extension rod 13 through this shaft. A hook-shaped feeding guide rod 46 is fixedly connected to the outer edge of the feeding shaft 45, and a feeding plate 47 is also fixedly connected to its outer edge. A transmission rod 48 extending towards the connecting shaft 42 is hinged to the feeding plate 47. A power rod 49 is rotatably connected to the connecting shaft 42. One end of the power rod 49 is hinged to the extension end of the transmission rod 48, and the other end of the power rod 49 is hinged to the blocking connecting rod 35.

[0045] Working principle: when the steel pipe is released by the steel pipe limiting mechanism 2, it is first temporarily blocked by the rotating rod 33 in the steel pipe blocking mechanism 3 to prevent the steel pipe from falling too much at one time. At this time, the blocking cylinder 36 is driven, the blocking cylinder 36 drives the rotating rod 33 to deflect through the blocking connecting rod 35, releases the blocked steel pipe, and makes it roll and be received by the limiting column 44 in the feeding mechanism 4.

[0046] Subsequently, the blocking cylinder 36 resets, and the rotating rod 33 again limits the upper layer of steel pipes; at the same time, the resetting action of the blocking cylinder 36 drives the power rod 49 to rotate around the connecting shaft 42 through the blocking connecting rod 35, the power rod 49 pulls the transmission rod 48, the feeding shaft 45 generates counterclockwise rotation, and further drives the feeding guide rod 46 to deflect upward, lifting the steel pipe stopped at the limiting column 44.

[0047] The lifted steel pipe rolls along the feeding guide rod 46 to its hook-shaped position, and when the blocking cylinder 36 is driven again, the feeding guide rod 46 moves downward, placing the steel pipe stably on the multiple pulleys arranged in the cold rolling push rod groove, and finally pushing the steel pipe on the pulley into the cold rolling equipment by the push rod to complete feeding.
