Description

Technical Field

[0001] This utility model relates to the field of punching device technology, and in particular to a punching device for seamless steel pipes. Background Technology

[0002] In the preparation of seamless steel pipes, the steel pipes need to be cold-drawn and pickled. To ensure the effect of cold drawing and pickling, the head of the steel pipe needs to be punched. CN207592553U discloses a seamless steel pipe punching device, including an upper die and a lower die. The upper die and the lower die are respectively provided with an upper extrusion chamber and a lower extrusion chamber on opposite sides. The upper die is provided with a through hole. On the side of the upper die away from the lower die, there is a cleaning component, a lifting component and a rotating component. The lifting component includes a first drive motor and a lifting plate. The lifting plate is provided with a lifting threaded hole whose surface thread is adapted to the lifting screw. The first drive motor drives the lifting screw connected to its output end. One end of the lifting screw is inserted into the lifting threaded hole, and the lifting screw drives the lifting plate to move up and down. The rotating component includes a second drive motor. The output end of the second drive motor is connected to a rotating shaft, and the rotating shaft is connected to a punch.

[0003] In the existing technology, when punching a steel pipe, the steel pipe needs to be fixed by a clamp before punching. However, since the punching position is located at the head of the steel pipe, it is easy to cause uneven force on both sides of the steel pipe during punching, resulting in unilateral deformation of the steel pipe and affecting the punching work. In addition, it is not easy to clean the punching debris that falls into the steel pipe during punching. Utility Model Content

[0004] This invention provides a seamless steel pipe punching device to solve the problems mentioned in the background art.

[0005] In view of this, the present invention aims to provide a seamless steel pipe punching device. In the present invention, the punching device includes a machine body and a conveying mechanism, a pushing mechanism, a fixing mechanism and a punching mechanism disposed in the machine body; the punching mechanism is disposed on the top of the fixing mechanism; the pushing mechanism is located on the side of the conveying mechanism away from the fixing mechanism, and is capable of pushing the steel pipe on the pushing mechanism into the fixing mechanism;

[0006] The fixing mechanism includes a first sleeve and a second sleeve. The first sleeve is disposed between the second sleeve and the conveying mechanism and allows the steel pipe to pass through. A punching area is formed between the first sleeve and the second sleeve, and the punching area is used by the punching mechanism to punch holes in the steel pipe.

[0007] This utility model, through the arrangement of a conveying mechanism, a pushing mechanism, and a fixing mechanism, enables the steel pipe on the conveying mechanism to be pushed into the fixing mechanism for punching, thereby achieving continuous punching and improving punching efficiency. In conjunction with the arrangement of the first sleeve, the second sleeve, and the punching area, the two ends of the steel pipe are limited on both sides of the punching area to ensure the uniformity of force on both sides when punching the steel pipe and improve the stability of punching.

[0008] Furthermore, one side of the second sleeve is for inserting the steel pipe, and the other side is provided with an adsorption port; the adsorption port is connected to a negative pressure device; the interior of the second sleeve is provided with a moving block, a return spring, a transmission gear, a sector gear, and an opening and closing block;

[0009] One side of the movable block can abut against the steel pipe and be driven to move by the steel pipe. The return spring is located on the side of the movable block away from the steel pipe. The side of the movable block is provided with teeth so that the movable block meshes with the transmission gear, and the other end of the transmission gear meshes with the sector gear.

[0010] The opening and closing block is slidably disposed inside the second sleeve and is capable of opening and closing the adsorption port; the side of the opening and closing block is provided with teeth so that the opening and closing block meshes with the sector gear.

[0011] By connecting a negative pressure device to one side of the second sleeve, the opening and closing block moves when the steel pipe is inserted into the second sleeve, causing the adsorption port to open, so that the adsorption port can directly adsorb the inside of the steel pipe, and can stably and timely clean the punching debris inside the steel pipe.

[0012] Furthermore, an arc-shaped guide plate is provided on the side of the moving block, and a protective cavity is formed between the arc-shaped guide plate and the moving block. The transmission gear and the sector gear are located inside the protective cavity.

[0013] By setting up the arc-shaped guide plate, the debris inside the steel pipe is stably discharged, and the arc-shaped plate can form a protective cavity during punching to prevent debris from adhering to the transmission gears and other structures, thus ensuring the stability of the transmission.

[0014] Furthermore, the first sleeve is installed inside the machine body through a connecting mechanism. The connecting mechanism includes a first fixing plate, a second fixing plate, and a locking screw. The first fixing plate is located at the upper end of the first sleeve, the second fixing plate is fixed at the bottom of the first sleeve, and the locking screw passes through the first fixing plate and the second fixing plate in sequence to lock and fix the first sleeve inside the machine body.

[0015] A positioning ring is fitted onto the locking screw; the positioning ring is located between the first fixing plate and the second sleeve, and is clamped and fixed by the first fixing plate and the second fixing plate; the positioning ring is connected to the second sleeve through a connecting rod.

[0016] The first and second fixed plates, locking screws, positioning rings, and connecting rods are used to position the first and second sleeves, ensuring coaxial installation and improving installation accuracy.

[0017] Furthermore, the pushing mechanism includes a pushing cylinder and a pushing plate. The pushing cylinder is installed in the machine body on the side of the conveying mechanism away from the fixed mechanism. The pushing plate is connected to the pushing cylinder and is controlled by the pushing cylinder to move on the conveying mechanism.

[0018] The pusher cylinder drives the pusher plate to move the steel plate on the conveying mechanism, saving manpower and ensuring the accuracy of pushing the steel pipe.

[0019] Furthermore, the punching mechanism includes a lifting cylinder, a lifting plate, and a punching unit. The lifting plate is slidably disposed inside the machine body. The lifting cylinder is connected to the lifting plate to control the movement of the lifting plate. The punching unit is mounted on the lifting plate.

[0020] By setting up a lifting cylinder and a lifting plate, the punching unit is placed on the lifting plate. During punching, the lifting plate is first controlled to descend, reducing the punching stroke of the punching unit and facilitating the maintenance of the connecting mechanism.

[0021] The seamless steel pipe punching device disclosed in this utility model fixes both sides of the steel pipe in the punching area with a first sleeve and a second sleeve, keeping the steel pipe under uniform stress in the punching part, improving the punching quality, and can stably adsorb the punching debris inside the steel pipe.

Detailed Implementation

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices. "Fixed" or "fixed connection" generally refers to common mechanical connection methods, such as threaded connections, welding, or bonding.

[0034] In the existing technology, when punching a steel pipe, the steel pipe needs to be fixed by a clamp before punching. However, since the punching position is located at the head of the steel pipe, it is easy to cause uneven force on both sides of the steel pipe during punching, resulting in unilateral deformation of the steel pipe and affecting the punching work. In addition, it is not easy to clean the punching debris that falls into the steel pipe during punching.

[0035] This utility model provides a punching device for seamless steel pipes, such as... Figure 1 As shown, in this embodiment, the punching device includes a body 100 and a conveying mechanism 200, a pushing mechanism 300, a fixing mechanism 400, and a punching mechanism 500 disposed within the body 100. The conveying mechanism 200 is configured as a steel pipe conveyor belt, at least partially located inside the body 100, for feeding and feeding steel pipes in and out, and the conveying mechanism 200 stops conveying during punching operations. The fixing mechanism 400 is used to fix the head of the steel pipe, and the punching mechanism 500 is provided on the top of the fixing mechanism 400 to punch the fixed steel pipe. The pushing mechanism 300 is located on the side of the conveying mechanism 200 away from the fixing mechanism 400, and the pushing mechanism 300 can push the steel pipe on the pushing mechanism 300, and at least push the head of the steel pipe into the fixing mechanism 400.

[0036] The pushing mechanism 300 includes a pushing cylinder 310 and a pushing plate 320. The pushing cylinder 310 is installed inside the machine body 100 and is located on the side of the conveying mechanism 200 away from the fixed mechanism 400. The pushing plate 320 is located at the upper end of the conveying mechanism 200 and is at the same height as the steel pipe on the conveying mechanism 200. The pushing plate 320 is connected to the pushing cylinder 310 and moves on the conveying mechanism 200 under the control of the pushing cylinder 310.

[0037] The punching mechanism 500 includes a lifting cylinder 510, a lifting plate 520, and a punching unit 530. The lifting plate 520 is horizontally arranged inside the machine body 100, and slide rails are provided on both sides inside the machine body 100 so that the lifting plate 520 can slide inside the machine body 100. The lifting cylinder 510 is connected to the lifting plate 520 to control the movement of the lifting plate 520. The punching unit 530 is installed on the lifting plate 520. During punching, the lifting cylinder 510 first drives the lifting plate 520 and the lifting unit to approach the steel pipe, and then the lifting unit punches the steel pipe.

[0038] like Figure 2 and Figure 3As shown, the fixing mechanism 400 is configured as a first sleeve 410 and a second sleeve 420. The first sleeve 410 is located between the second sleeve 420 and the conveying mechanism 200. The steel pipe first passes through the first sleeve 410 and then is inserted into the second sleeve 420. The first sleeve 410 and the second sleeve 420 are spaced apart, forming a punching area 430 between the first sleeve 410 and the second sleeve 420. The punching mechanism 500 punches the steel pipe in the punching area 430. By setting the first sleeve 410 and the second sleeve 420, the two ends of the steel pipe are limited on both sides of the punching area 430 to ensure the uniformity of the force on both sides when punching the steel pipe.

[0039] In order to enable the removal of impurities from the punching inside the steel pipe, such as Figure 4 As shown, a steel pipe is inserted into one side of the second sleeve 420, and an adsorption port 421 is provided on the other side; the adsorption port 421 is connected to a negative pressure device, and the adsorption work is carried out on the inside of the steel pipe through the negative pressure device.

[0040] In addition, such as Figure 5 As shown, a movable block 422, a return spring 423, a transmission gear 424, a sector gear 425, and an opening / closing block 426 are arranged inside the second sleeve 420. When the steel pipe is inserted into the second sleeve 420, the steel pipe abuts against one side of the movable block 422 and pushes the movable block 422 to move. After the movable block 422 is pushed to the point where it can no longer move, it indicates that the steel pipe is in place and the punching operation begins. The return spring 423 is located on the side of the movable block 422 away from the steel pipe. When the movable block 422 moves... The compression return spring 423 drives the moving block 422 to reset after the steel pipe is disengaged from the second sleeve 420. The moving block 422 is provided with teeth on its side, so that the moving block 422 meshes with the transmission gear 424, and the other end of the transmission gear 424 meshes with the sector gear 425. The opening and closing block 426 is slidably disposed in the second sleeve 420 and can open and close the suction port 421. The opening and closing block 426 is provided with teeth on its side, so that the opening and closing block 426 meshes with the sector gear 425.

[0041] In addition, an arc-shaped guide plate 427 is provided on the side of the moving block 422, and a protective cavity is formed between the arc-shaped guide plate 427 and the moving block 422. The transmission gear 424 and the sector gear 425 are located inside the protective cavity. With the setting of the arc-shaped guide plate 427, the debris inside the steel pipe is stably discharged, and the arc-shaped plate can form a protective cavity during punching to prevent debris from being adsorbed onto the transmission gear 424 and other structures.

[0042] In this invention, when punching a steel pipe, the conveying mechanism 200 first transports the steel pipe to a position flush with the pushing mechanism 300. The pushing cylinder 310 drives the pushing plate 320 to push the steel pipe in the opposite direction toward the fixing mechanism 400, causing the head of the steel pipe to pass through the first sleeve 410 and insert into the second sleeve 420. This pushes the moving block 422 to compress the return spring 423. As the moving block 422 moves, it drives the transmission gear 424 to rotate, which in turn drives the sector gear 425 to rotate. When the sector gear 425 rotates, the opening and closing block 42... 6. Move the two opening and closing blocks 426 away from each other, open the suction port 421, and at this time the negative pressure device is connected to the inside of the steel pipe. At this time, the punching mechanism 500 performs punching work, and the negative pressure device sucks out the punching debris inside the steel pipe. After the punching work is completed, the pushing mechanism 300 retracts and no longer applies pushing force to the steel pipe. Under the action of the return spring 423, the steel pipe is driven to return to its original position and pass through the first sleeve 410 and the second sleeve 420. The steel pipe returns to the conveying mechanism 200, and the conveying mechanism 200 restarts to send out the punched steel pipe.

[0043] By incorporating a moving block 422, a return spring 423, a transmission gear 424, a sector gear 425, and an opening / closing block 426 within the second sleeve 420, the adsorption port 421 automatically opens when the steel pipe enters the second sleeve 420 and automatically closes when the steel pipe detaches from the fixing mechanism 400, stopping the adsorption of the inside of the steel pipe. This automatic opening and closing mechanism eliminates the need for frequent control of the negative pressure equipment, ensuring stable operation of the negative pressure equipment and extending its service life.

[0044] To ensure the stability of the steel pipe inserted into the first fixing mechanism 400 and to prevent the steel pipe from shifting; such as Figure 2 As shown, the first sleeve 410 is installed inside the machine body 100 via a connecting mechanism. The connecting mechanism includes a first fixing plate 440, a second fixing plate 450, and a locking screw 460. The first fixing plate 440 is located at the upper end of the first sleeve 410, and the second fixing plate 450 is fixed at the bottom of the first sleeve 410. That is, the position of the first sleeve 410 is determined when the second fixing plate 450 is installed and fixed. The locking screw 460 passes through the first fixing plate 440 and the second fixing plate 450 in sequence to lock and fix the first sleeve 410 inside the machine body 100. A fixed screw is sleeved on the locking screw 460. Positioning ring 470; The positioning ring 470 is located between the first fixing plate 440 and the second sleeve 420, and is clamped and fixed by the first fixing plate 440 and the second fixing plate 450; The positioning ring 470 is connected to the second sleeve 420 through the connecting rod 480, and the positioning ring 470 is fixed on the first sleeve 410 through the first fixing plate 440 and the second fixing plate 450. With the setting of the connecting rod 480, the second sleeve 420 is installed and fixed, ensuring the coaxial installation of the first sleeve 410 and the second sleeve 420, improving the installation accuracy, and thus improving the accuracy of steel pipe punching.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
