Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe feeding, in particular to a steel pipe feeding device and a feeding method. Background Art

[0002] Steel pipe is a slender tubular rod. In the process of processing it into other parts, it is generally necessary to set up a feeding mechanism to automatically push the steel pipe to move. The steel pipe feeding mechanism can greatly reduce the labor intensity of the staff and greatly improve work efficiency.

[0003] Existing steel pipe feeding devices are prone to confusion when conveying short steel pipes. For example, Publication No. CN107892169A discloses a steel pipe separation feeding mechanism, which uses an inclined conveying plate to achieve rolling unloading of steel pipes. However, when in use, the mechanism does not have a structure to limit the position of the steel pipes, which results in the short steel pipes not being unloaded in an orderly manner.

[0004] In addition, the existing steel pipe feeding device also includes a structure for pushing the steel pipe to move. By pushing the steel pipe to move, it can be easily processed and gradually processed into other parts. The existing structure for pushing the steel pipe to move is mostly a structure combined with a screw rod and a push block, which requires controlling the frequency of the forward and reverse rotation of the servo motor to facilitate the reciprocating movement of the push block, thereby achieving the purpose of automatic processing;

[0005] However, since the servo motor needs to rotate forward and reverse, the service life of the servo motor is shorter than that of an ordinary motor that only rotates in one direction, which in turn increases production costs. In addition, if the servo motor fails during use and causes its forward and reverse frequency to change, the production process will be interrupted, which is not conducive to ensuring orderly and stable production.

[0006] Therefore, a steel pipe feeding device is needed to solve the above problems. Summary of the Invention

[0018] A steel pipe feeding method, comprising:

[0019] Step 1: According to the length of the steel pipe, rotate the screw to adjust the position of the movable plate so that the distance between the movable plate and the limit plate is slightly larger than the length of the steel pipe;

[0020] Step 2: Lay the steel pipe on the storage table and then start the motor;

[0021] Step 3: The motor rotates the driving bevel gear, driving the two driven bevel gears to rotate, and then connects with one of the two docking sleeves through the docking tube, driving the screw to rotate, and the rotation of the screw drives the push frame to move;

[0022] Step 4: The push frame moves, driving the push plate to move, thereby pushing the steel pipe in the feed trough to move;

[0023] Step 5: After the steel pipe in the feed trough is used up, the push frame continues to move, squeezing the relative docking ring. After the spring 3 is compressed to a certain extent, the screw rod moves. During this process, the universal ball first moves into the inner groove and then pops out, causing the universal ball to slide from the original limit ring to the other limit ring;

[0024] During the process, the butt joint tube moves synchronously with the screw rod, so that the butt joint tube can gradually connect with the other butt joint sleeve. At this time, the rotation direction of the screw rod changes and the push frame moves in the opposite direction.

[0025] Step 6: The push frame drives the push plate to move in the reverse direction, gradually squeezing the wedge block, causing the twist rod to drive the worm gear assembly to rotate, thereby driving the shaft tube to rotate. The rotation of the shaft tube can rotate the main baffle and the auxiliary baffle, thereby releasing the steel pipe between the main baffle and the auxiliary baffle, allowing it to slide into the feed chute;

[0026] Step 7: The push frame moves in the reverse direction, squeezing the other opposite docking ring, changing the rotation direction of the screw again, thereby facilitating the forward movement of the push frame, driving the push plate to push the steel pipe in the feed trough to move.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: the steel pipe feeding device can adjust the position of the movable plate according to the length of the steel pipe, and then cooperate with the limit plate to limit the steel pipe to ensure that it enters the feed trough in an orderly manner. In addition, through the adjustable reciprocating pushing mechanism, the motor can rotate in only one direction to achieve the forward and reverse rotation of the screw rod, thereby avoiding the use of servo motors and related equipment, thereby helping to reduce production costs. In addition, since ordinary motors that only rotate in one direction have a long service life and a low failure rate, orderly and stable production operations can be ensured:

[0028] 1. By rotating the screw, the position of the movable plate can be adjusted, and the distance between the movable plate and the limit plate can be changed, so as to facilitate the positioning of steel pipes of different lengths and avoid the problem that the steel pipes may not fall in an orderly manner due to the long distance between the movable plate and the limit plate when the steel pipes are short. In addition, since the shaft tube and the shaft rod are nested and connected, the structure formed by the shaft tube and the shaft rod can be prevented from hindering the movement of the movable plate relative to the limit plate;

[0029] 2. The adjustable reciprocating pusher mechanism changes the direction of rotation of the screw rod after the pusher frame moves to a certain extent, thereby facilitating the reciprocating movement of the push plate. In addition, by adjusting the position of the collar, the reciprocating distance of the push plate can be changed to match steel pipes of different lengths, which is beneficial to improving the pushing efficiency. During the process, there is no need to use a servo motor and related matching equipment, which not only helps to save costs, but also ensures orderly and stable production due to the relatively low failure rate of ordinary motors.

[0030] 3. When the push plate moves back and forth, it can squeeze the wedge block, and then cooperate with spring 2 to realize the positive and negative rotation of the shaft tube, so that the main baffle can intermittently release the steel tube, so that the steel tube can enter the feed trough in an orderly manner.

[0048] The adjustable reciprocating pushing mechanism also includes a screw rod 4 that movably passes through the two driven bevel gears 25, and the driven bevel gear 25 and the screw rod 4 are coaxially arranged. The outer side of the screw rod 4 is threadedly connected to a push rack 5, and the push rack 5 is movably penetrated by a limit rod 30. The limit rod 30 and the screw rod 4 are arranged parallel to each other. A push plate 31 is connected to the push rack 5, and the push plate 31 is arranged in the feed trough 13. The opposite sides of the support cover 2 are slidably penetrated and connected with a sliding tube 44, and the two sliding tubes 44 are respectively connected to the bearings at both ends of the screw rod 4. The reciprocating pusher mechanism also includes a butt joint 27 fixedly connected to the outside of the screw rod 4, and the butt joint 27 is arranged between the two driven bevel gears 25, and the opposite sides of the two driven bevel gears 25 are fixedly provided with a butt joint sleeve 26 coaxial therewith, and the two ends of the butt joint 27 are frustum structures, and the inner side of the butt joint sleeve 26 is also a frustum structure, and the frustum structure on the butt joint 27 is consistent with the frustum structure on the butt joint sleeve 26, and the frustum structures on the butt joint 27 and the butt joint sleeve 26 are provided with rubber pads for increasing In order to increase the friction force after the corresponding frustum structure is docked, the adjustable reciprocating pushing mechanism also includes a limit sleeve 18 fixedly connected to the outside of the screw rod 4, the limit sleeve 18 is arranged at one end of the screw rod 4 farther from the support plate 3, and two limit rings 19 are arranged on the outside of the limit sleeve 18. A mounting ring 22 is installed on the support cover 2 farther from the support plate 3 through a mounting bracket 21, and the mounting ring 22 is coaxially sleeved on the outside of the limit sleeve 18, and inner grooves 23 are distributed at equal angles on the inner side of the mounting ring 22, and the inner grooves 23 are elastically supported. Spring 1 24 is connected to the universal ball 20, and the universal ball 20 is slidably connected to the corresponding limit ring 19. The adjustable reciprocating pushing mechanism also includes a positioning groove 39 provided on the limit rod 30, and two rings 37 and two docking rings 40 are sleeved on the outer side of the limit rod 30.

[0049] according to Figure 3-Figure 5 、 Figure 9-10 as well as Figure 12-13 , start the motor 7, so that the driving bevel gear 17 drives the driven bevel gear 25 to rotate, and then the butt joint 27 can be connected with the butt joint sleeve 26 on one side, so that the screw rod 4 rotates in the positive direction, thereby driving the push frame 5 and the push plate 31 to move synchronously, thereby pushing the steel pipe to move;

[0050] After the steel pipe is used up, the push frame 5 continues to move, squeezing the docking ring 40 on the moving side, compressing the corresponding spring 3 41. When the spring 3 41 is compressed to a certain extent, the screw rod 4 will move, causing the universal ball 20 to first move into the inner groove 23 and then pop out, thereby causing the universal ball 20 to move from the original limit ring 19 to the other limit ring 19;

[0051] During the process, the butt joint 27 will be connected with the butt joint sleeve 26 on the other side, thereby causing the screw rod 4 to rotate in the reverse direction, so that the push frame 5 and the push plate 31 can move in the reverse direction and reset;

[0052] After the push frame 5 contacts the docking ring 40 on its moving side and squeezes the corresponding spring 3 41, the rotation direction of the screw rod 4 will change again, thereby driving the push frame 5 and the push plate 31 to push the next steel pipe to move;

[0053] In the above process, there is no need to use a servo motor or equipment that is compatible with the servo motor to achieve the reciprocating movement of the push plate 31, which can greatly reduce production costs. In addition, the reciprocating stroke of the push plate 31 can be adjusted as needed, which helps to match steel pipes of different lengths. In addition, since there is no need to use a servo motor, its failure rate is relatively lower, which is conducive to orderly and stable production.

[0054] Example 2: In order to solve the problem that the previous steel pipe feeding mechanism was not equipped with a structure to limit the steel pipe, resulting in the inability to unload steel pipes of smaller lengths in an orderly manner, the following technical solution is provided. Specifically, a limiting plate 9 is provided on the storage table 8, and an adjustable discharge mechanism is also installed on the storage table 8. The adjustable discharge mechanism includes a movable plate 10 that is opposite to the limiting plate 9, and a feed trough 13 is provided at the lower end of the storage table 8 near the support cover 2.

[0055] The adjustable feeding mechanism also includes a strip groove 28 provided on the storage platform 8, and the protrusion connected to the movable plate 10 is slidably connected to the strip groove 28, the protrusion is threadedly connected to a screw 29, and the screw 29 is connected to the strip groove 28 in a bearing. The axis of the strip groove 28 is colinear with the axis of the screw 29, which is used to control the movable plate 10 to move along the axis direction of the strip groove 28. The adjustable feeding mechanism also includes a shaft 15 with one end bearing connected to the limit plate 9, one end of the shaft tube 14 is connected to the bearing on the movable plate 10, and the other end of the shaft tube 14 is connected to the shaft tube 14. The other end of the shaft 15 is movably nested, and the part of the shaft 15 extending into the shaft tube 14 is a prismatic structure. The inner side of the shaft tube 14 is provided with a prismatic groove that matches the prismatic structure of the shaft tube 14, so that the shaft tube 14 and the shaft 15 can always rotate synchronously. The end of the shaft tube 14 close to the movable plate 10 and the end of the shaft 15 close to the limit plate 9 are fixedly connected to the main baffle 16, and the main baffle 16 is distributed with magnetic grooves 42, and only one magnetic groove 42 is magnetically connected to the auxiliary baffle 43. The slider 11 is fixedly connected to the movable plate 10, and the feed The side of the groove 13 is provided with a slide groove 12, and the slider 11 is slidably connected to the slide groove 12. The adjustable discharge mechanism also includes a mounting block 32 fixedly connected to the movable plate 10 toward the side of the limit plate 9, and a twist rod 33 is movably penetrated on the mounting block 32. The twist rod 33 is fixedly connected to one end of the slide groove 12 with a wedge block 34, and a spring 2 36 is provided between the other end of the twist rod 33 and the mounting block 32, and the position of the wedge block 34 corresponds to the position of the push plate 31. The outer side of the twist rod 33 is fixedly connected to the wedge block 34. The worm gear assembly 35 is connected to the shaft tube 14. The worm gear assembly 35 consists of a worm and a worm wheel. The worm bearing is connected to the mounting block 32, and the twisted rod 33 is threaded through the worm setting. The worm wheel is mounted on the shaft tube 14. The part of the twisted rod 33 that movably passes through the mounting block 32 is a prismatic rod, and the mounting block 32 is provided with a prismatic through hole that matches the prismatic rod, which is used for the prismatic rod to movably pass through the mounting block 32, thereby limiting the twisted rod 33 and preventing it from rotating. The prismatic rod is a T-shaped structure, which is convenient for supporting the spring 2 36.

[0056] according to Figure 1-Figure 2 、 Figure 6-Figure 8 as well as Figure 11 When in use, the screw 29 can be rotated according to the length of the steel pipe, and the position of the movable plate 10 can be adjusted so that the distance between the movable plate 10 and the limiting plate 9 is slightly larger than the length of the steel pipe, thereby facilitating the positioning of steel pipes of different lengths and avoiding the situation where the steel pipe is too short and the distance between the movable plate 10 and the limiting plate 9 is too large, resulting in the inability to unload the steel pipe in an orderly manner;

[0057] In addition, because the shaft tubes 14 and the shaft tubes 14 are limited and nested, it can be ensured that the structure formed by the two can be extended and retracted, and the two can rotate synchronously;

[0058] During the reciprocating movement of the push plate 31, the wedge block 34 is squeezed, thereby moving the twist rod 33 and causing the second spring 36 to accumulate elastic potential energy. During the movement of the twist rod 33, the worm gear assembly 35 drives the shaft tube 14 to rotate, and the nested shaft 15 thereof rotates synchronously, thereby causing the main baffle 16 to rotate. When the main baffle 16 rotates, it releases the steel pipe between it and the auxiliary baffle 43, and the auxiliary baffle 43 can prevent the subsequent steel pipe from falling, thereby causing only one steel pipe to fall into the feed chute 13, so that the push plate 31 only pushes one steel pipe to move. During the process of the push plate 31 pushing the steel pipe to move, it gradually moves away from the wedge block 34, thereby causing the twist rod 33 to reset under the action of the second spring 36, so that the main baffle 16 can reset;

[0059] By reciprocating the push plate 31 and continuously squeezing the wedge block 34, the steel pipe can be gradually released and pushed to move, thereby automatically feeding the steel pipe.

[0060] A steel pipe feeding method, the method comprising:

[0061] Step 1: According to the length of the steel pipe, rotate the screw 29 to adjust the position of the movable plate 10 so that the distance between the movable plate 10 and the limit plate 9 is slightly larger than the length of the steel pipe;

[0062] Step 2: Lay the steel pipe on the storage platform 8, and then start the motor 7;

[0063] Step 3: The motor 7 rotates the driving bevel gear 17, driving the two driven bevel gears 25 to rotate, and then connects with one of the two docking sleeves 26 through the docking tube 27, driving the screw rod 4 to rotate, and the rotation of the screw rod 4 drives the push frame 5 to move;

[0064] Step 4: The push frame 5 moves, driving the push plate 31 to move, thereby pushing the steel pipe in the feed trough 13 to move;

[0065] Step 5: After the steel pipe in the feed trough 13 is used up, the push frame 5 continues to move, squeezing the opposite docking ring 40, so that the spring 3 41 is compressed to a certain extent, and the screw rod 4 is displaced. During this process, the universal ball 20 first moves into the inner groove 23 and then pops out, thereby causing the universal ball 20 to slide from the original limit ring 19 to the other limit ring 19;

[0066] During the process, the butt joint 27 moves synchronously with the screw rod 4, so that the butt joint 27 can be gradually connected with the other butt joint sleeve 26. At this time, the rotation direction of the screw rod 4 changes, and the push frame 5 moves in the reverse direction.

[0067] Step 6: The push frame 5 drives the push plate 31 to move in the reverse direction, gradually squeezing the wedge block 34, causing the twisted rod 33 to drive the worm gear assembly 35 to rotate, thereby driving the shaft tube 14 to rotate. The rotation of the shaft tube 14 can rotate the main baffle 16 and the auxiliary baffle 43, thereby releasing the steel pipe between the main baffle 16 and the auxiliary baffle 43, allowing it to slide into the feed chute 13;

[0068] Step 7: The push frame 5 moves in the reverse direction, squeezing the other opposite docking ring 40, and changing the rotation direction of the screw rod 4 again, thereby facilitating the push frame 5 to move in the forward direction, driving the push plate 31 to push the steel pipe in the feed trough 13 to move.

[0070] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
