Description

Technical Field

[0001] The invention relates to the technical field of steel pipe processing, in particular to a novel walking furnace. Background Art

[0002] During the processing of steel pipes, the round steel needs to be placed in a walking furnace for high-temperature heating, and then transferred to the next process through the transmission track. When a batch of round steel is placed at the feeding port of the walking furnace, due to the uneven ends of multiple batches of round steel, when the round steel is transferred into the walking furnace, it is easy to be blocked, and it is necessary to manually sort the round steel at the feeding port, which is time-consuming, labor-intensive and inconvenient to operate. After the round steel in the walking furnace is heated, the round steel in the furnace is placed one by one on the output mechanism through the moving bed and transmitted out. Traditionally, the moving bed can only place one round steel on the output mechanism once, and the moving bed takes a long time to move once. In this way, the round steel has problems of slow transmission rate, low output and high energy consumption during the transmission process.

[0003] In addition, since the round steel itself is long and the equipment used to process the round steel is also large, after the round steel passes through the high-temperature furnace, it is transmitted to the next few processes through the straight transmission track of the transmission mechanism to complete a series of processing processes. In this way, the path across in the same direction is long, and the round steel cannot achieve automatic turning and reversing during the transmission process. Therefore, the site is very limited, the waste of site resources is serious, and there is a problem of high cost. Summary of the invention

[0004] The purpose of the present invention is to provide a new walking beam furnace, which has the effects of saving time and labor, convenient operation, fast transmission, high yield and low energy consumption, saving site resources and effectively reducing costs.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a new walking furnace, comprising a walking furnace body, the walking furnace body is provided with a fixed bed, a movable bed and a driving component for driving the fixed bed to move, a feeding mechanism is provided at the feeding port of the walking furnace body, and a discharging mechanism and a turning transmission mechanism are provided at the discharging port of the walking furnace body;

[0006] The feeding mechanism includes a feeding rack and a bracket arranged on the side of the feeding rack, and a regularizing device is arranged on the bracket;

[0007] A discharging cavity is arranged at the discharging port, and the discharging mechanism includes a plurality of rotating shafts rotatably connected to the discharging cavity, a first driving device for driving the rotating shaft to rotate is arranged on the rotating shaft, a large V-shaped roller and a small V-shaped roller are coaxially arranged on each rotating shaft, the large V-shaped rollers on the plurality of rotating shafts form a large roller row, and the small V-shaped rollers on the plurality of rotating shafts form a small roller row;

[0008] The turning transmission mechanism includes an arc-shaped transmission track, which includes an arc-shaped inner wall and an arc-shaped outer wall. An arc-shaped channel is formed between the arc-shaped inner wall and the arc-shaped outer wall. A plurality of tapered rollers are sequentially arranged in the arc-shaped channel along the arc-shaped transmission track. The tapered rollers are rotatably connected to the arc-shaped transmission track through a rotating shaft, and the tapered rollers are driven by a second driving device.

[0009] By adopting the above technical solution, the round steel is placed on the feeding rack. When the round steel rolls down to the feeding port, the tidying device pushes the two ends of the round steel to be arranged so that the ends of several round steels are flush. After the round steel enters the furnace, the driving component drives the movable bed to move. When the movable bed moves relative to the fixed bed, the round steel in the furnace of the walking furnace body can be transferred to the discharge cavity through the movable bed. Two round steels can be transferred each time the movable bed moves. When the movable bed exits the discharge cavity, a round steel is placed in the large On the roller row, another round steel is placed on the small roller row. When the first driving device drives the rotating shaft to rotate, since the large V-shaped roller and the small V-shaped roller on the same rotating shaft have the same rotation speed, and the diameter of the large V-shaped roller at the contact surface with the round steel is larger, and the diameter of the small V-shaped roller at the contact surface with the round steel is smaller, when the rotating shaft rotates, the round steel placed on the large roller row is transmitted out of the discharge cavity first compared to the round steel placed on the small roller row, and then the round steel on the small roller row follows. When the high-temperature heated round steel is sent out from the discharge port and enters the arc transmission track, the second driving device is started, and the corresponding conical rollers are driven to rotate. When the conical rollers convey the round steel, the round steel will generate centripetal force, and the side wall of the conical roller can provide horizontal support for the round steel, so that the round steel can be transmitted in an arc shape with the center of the arc transmission track as the center during the transmission process in the arc channel. The horizontal support force of the conical roller can prevent the round steel from leaving the track due to the centripetal force during the transmission process. In this way, the round steel is arranged by the sizing device during feeding, which has the effect of saving time and labor and convenient operation; when discharging, a large roller row and a small roller row are arranged in the discharging chamber, so that the two round steels transmitted to the discharging chamber through the moving bed each time can be transmitted in sequence. In this way, compared with the existing technology, it has the effect of speeding up transmission, increasing production, and saving energy consumption, and the sized round steel is orderly when the large and small roller rows are transmitted, and it is not easy to collide; it is transmitted through the arc transmission track, and a turn and reversal are formed during the transmission process, which can reduce the overall length of the transmission, greatly reduce the required length of the factory building, have the effect of reducing the floor area, saving site resources, and effectively reducing costs.

In this way, the left and right push plate assemblies can move toward each other and respectively correspond to the two ends of the round steel, and multiple round steels can be regularized at the same time.

[0046] A new type of walking furnace, such as Figure 1 and Figure 7As shown, it includes a walking furnace body 1, a feed port is provided at the front end of the walking furnace body 1, a discharge port is provided at the rear end of the walking furnace body 1, the walking furnace body 1 is provided with a fixed bed 11, a movable bed 12 and a driving component 13 for driving the fixed bed 11 to reciprocate between the feed port and the discharge port, a feeding mechanism 2 is provided at the feed port of the walking furnace body 1, and a discharge mechanism 3 and a turning transmission mechanism 4 are provided at the discharge port of the walking furnace body 1.

[0047] like Figure 1-5 As shown, the feeding mechanism 2 includes an inclined feeding frame 21 and a left bracket 22 and a right bracket 23 arranged on both sides of the feeding frame 21, and a tidying device is arranged on the left and right brackets; a connecting rod 24 is arranged between the left bracket 22 and the right bracket 23, and the tidying device includes a right push plate assembly 26 arranged on the connecting rod 24 and a left push plate assembly 25 arranged on the left bracket 22, and the left push plate assembly 25 and the right push plate assembly 26 are arranged opposite to each other, and the left push plate assembly 25 and the connecting rod 24 are linked by a linkage structure. A sliding cavity is provided on the left bracket 22, and a support roller 221 is rotatably arranged in the sliding cavity. The left push plate assembly 25 includes a horizontally arranged push rod 251 and a left push plate 252 arranged at the right end of the push rod 251, and the push rod 251 is located in the sliding cavity, and the support roller 221 and the bottom surface support of the push rod 251 are rollingly matched. A thrust cylinder 222 for driving the push rod 251 to move is fixedly arranged on the left bracket 22, and a connecting block 2511 is arranged on the push rod 251, and a piston rod of the thrust cylinder 222 is fixedly connected to the connecting block 2511. Two sets of guide rollers 223 symmetrically located on the sides of the push rod 251 are also arranged on the left bracket 22, and the side walls of the guide rollers 223 are in rolling cooperation with the push rod 251. The arrangement of the guide rollers 223 enables the push rod 251 to have a better guiding effect when moving, and prevents the push rod 251 from being offset in the process of moving.

[0048] like Figure 4 and Figure 5 As shown, the linkage structure includes a first rack 2512, a second rack 241 and a gear 224. The first rack 2512 is fixedly connected to the push rod 251, the second rack 241 is fixedly connected to the connecting rod 24, and the gear 224 is rotatably connected to the left bracket 22. The first rack 2512 and the second rack 241 are both meshed with the gear 224. When the push rod 251 moves to drive the gear 224 to rotate, the connecting rod 24 moves in the opposite direction relative to the push rod 251. A pressure roller 225 is rotatably provided on the left bracket 22. The pressure roller 225 is abutted against the top wall of the connecting rod 24. The pressure roller 225 is provided above the connecting rod 24. The pressure roller 225 can prevent the end of the connecting rod 24 from warping up during the movement to a certain extent, so that the connecting rod 24 has a better positioning and stabilizing effect.

After the regularization is completed, the left push plate assembly 25 moves in the opposite direction away from the round steel 10, and the connecting rod 24 can drive the right push plate assembly 26 away from the round steel 10. When the push rod 251 moves, the support roller 221 can play a good supporting role for the push rod 251. The setting of the guide roller 223 enables the push rod 251 to have a good guiding role when moving, preventing the push rod 251 from being offset during the movement. Since the bottom wall of the connecting rod 24 abuts against the side wall of the driven roller 231 , the driven roller 231 can be driven to rotate. The driven roller 231 has a good supporting effect on the connecting rod 24 , reducing the friction when the connecting rod 24 moves.

The V-grooves of the large V-shaped roller 313 and the small V-shaped roller 314 have the same inclination angle. The large V-shaped rollers 313 on several rotating shafts 31 form a large roller row, and the small V-shaped rollers 314 on several rotating shafts 31 form a small roller row.

The front rollers are rotatably connected to the front straight track 6 through rotating shafts. The front rollers include a V-shaped roller 61 and a plurality of straight rollers 62. The V-shaped roller 61 is arranged near the discharge port end. The front straight track 6 is provided with a first transmission motor 63. The output shaft of the first transmission motor 63 drives the plurality of rotating shafts to rotate through a plurality of first belts 64. After the first transmission motor 63 is started, the front roller on the rotating shaft is driven to rotate through the first belt 64. During the rotation of the front roller, the round steel 10 sent out from the stepping furnace can be driven to be transmitted from the entrance of the front straight track 6 to the entrance of the arc transmission track 41. The V-shaped roller 61 can play a central guiding role for the round steel 10 sent out from the discharge port, so that the round steel 10 is transmitted along the middle part of the straight roller 62 in the subsequent straight roller 62, reducing the position deviation of the round steel 10 during the transmission process. The front straight track 6 can provide a certain acceleration and buffering effect for the round steel 10 entering the arc transmission track 41.

[0055] After the first transmission motor 63 is started, the front roller on the rotating shaft is driven to rotate through the first belt 64. During the rotation of the front roller, the round steel 10 transmitted from the stepping furnace can be driven to be transmitted from the entrance of the front straight track 6 to the entrance of the arc transmission track 41. The front straight track 6 can provide a certain acceleration and buffering effect for the round steel 10 to enter the arc transmission track 41. The V-shaped roller 61 can guide the round steel 10 on the large roller row and the small roller row respectively, so that the round steel 10 can always be transmitted in the center of the straight roller 62 without deviation during the transmission process.

[0056] like Figure 2 and Figure 9-10As shown, the turning transmission mechanism 4 includes an arcuate transmission track 41, and the arcuate transmission track 41 includes an arcuate inner wall 411 and an arcuate outer wall 412. An arcuate channel 413 is formed between the arcuate inner wall 411 and the arcuate outer wall 412. The gap width of the arcuate channel 413 is set to 28-35 cm. In the present embodiment, the gap of the arcuate channel 413 is controlled at 30 cm. A plurality of tapered rollers 7 are sequentially arranged along the arcuate transmission track 41 in the arcuate channel 413. The number of tapered rollers 7 can be set to 8-13. The tapered rollers 7 are rotatably connected to the arcuate transmission track 41 through a rotating shaft. The central axis of the rotating shaft is arranged along the radial direction of the arcuate transmission track 41. The arcuate transmission track 41 is provided with a second driving device and an electric control box for controlling the operation of the driving mechanism. The second driving device includes a driving motor 73 connected to the rotating shaft 31 in a one-to-one correspondence. The output shaft of the driving motor 73 is fixedly connected to the rotating shaft. When the driving motor 73 is started, the tapered roller 7 can be driven to rotate through the rotating shaft. The end of the tapered roller 7 close to the arc-shaped inner wall 411 is set as a small head 71, and the end of the tapered roller 7 close to the arc-shaped outer wall 412 is set as a large head 72. The diameter of the tapered roller 7 gradually decreases from the large head 72 to the small head 71. The side wall between the large head 72 and the small head 71 forms an inclined outer wall. The diameter of the cross section of the small head 71 of the tapered roller 7 is set to 10 cm, and the diameter of the cross section of the large head 72 of the tapered roller 7 is set to 12 cm. The inclination angle α between the inclined outer wall of the tapered roller 7 and the central axis of the tapered roller 7 is set to 3.58°.

[0057] like Fig.11 As shown, the arc angle β1 of the arc-shaped inner wall 411 is set to 58°, the arc length s1 of the arc-shaped inner wall 411 is set to 4600 mm, the arc angle β2 of the arc-shaped outer wall 412 is set to 77°, and the arc length s2 of the arc-shaped outer wall 412 is set to 5400 mm.

[0058] The centripetal force provided by the tapered roller 7 is F1 = mgsinα, and the centripetal force required by the round steel 10 being transported is F2 = m(s / t) 2 / R, F1>F2 between F1 and F2, then m is the mass of the round steel, s is the arc length of the arc transmission track, R is the radius of the arc transmission track, t is the total time for the round steel to be transmitted on the arc transmission track, and g is the gravity coefficient. In this embodiment, when s is the length of the arc inner wall 411 of 4600mm, t should be greater than 2.8s; the speed n set by the drive motor 73 satisfies the following formula: L×N×60 / (12π×t)<n<L×N×60 / (10π×t), L is the length of the round steel to be transmitted, N is the number of tapered rollers on the arc transmission track, and t is the time for the round steel to be transmitted on the arc transmission track. In this embodiment, the length L of the round steel to be transmitted is 1.45 meters, the diameter is 5cm, the number of tapered rollers is set to 13, the transmission time is set to 3s, and the speed n is set to 1100 rpm.

[0059] According to the length of the round steel 10 being transported and the number of tapered rollers 7 set, the rotation speed of the drive motor 73 can be adaptively adjusted, so that it can be suitable for transporting round steels 10 of various lengths. It is more flexible to use and there is no need to replace equipment to transport different round steels 10, which can effectively reduce costs.

[0060] like Fig. 9 As shown, the outlet of the arc-shaped transmission track 41 is provided with a rear straight track 8, and a plurality of rear rollers 81 are provided in the rear straight track 8. The rear rollers 81 are rotatably connected to the rear straight track 8 through a rotating shaft. The rear straight track 8 is provided with a second transmission motor 82, and the output shaft of the second transmission motor 82 drives the plurality of rotating shafts to rotate through a plurality of second belts 83. After the second transmission motor 82 is started, the rear rollers 81 on the rotating shafts are driven to rotate through the second belts 83. During the rotation process of the rear rollers 81, the round steel 10 transmitted from the arc-shaped transmission track 41 can be received and transmitted to the next process, playing a transition role.

[0061] like Figure 1 and Fig. 9 As shown, a diverter assembly 9 is provided at the outlet of the rear straight track 8, and the diverter assembly 9 includes a diverter platform 91, and a fixed rod 92 is provided on the diverter platform 91, and the fixed rod 92 is arranged along the outgoing direction of the round steel 10, and a flap is rotatably connected to the fixed rod 92, and the flap includes a first flap 93 and a second flap 94, and the first flap 93 and the second flap 94 are arranged opposite to each other and form a V shape. The diverter assembly 9 also includes a first driving cylinder 95 and a second driving cylinder 96, and the first driving cylinder 95 drives the first flap 93 to flip relative to the fixed rod 92, and the second driving cylinder 96 drives the second flap 94 to flip relative to the fixed rod 92, and guide platforms 97 corresponding to the flaps are provided on both sides of the diverter platform 91.

[0062] In the initial state, the first flap 93 and the second flap 94 are respectively in an upward slanting state, and the two flaps are V-shaped as a whole. The round steel 10 is sent into the V-shaped groove of the two flaps under the transmission action of the rear straight track 8, and the first driving cylinder 95 drives the first flap 93 to flip downward. When the first flap 93 flips below the horizontal line, the round steel 10 rolls along the first flap 93 to the guide platform 97 under the guidance of the inclined surface of the first flap 93. Subsequently, the first driving cylinder 95 drives the first flap 93 to reset. When the next one is transmitted to the V-shaped groove, the second driving cylinder 96 is started to flip the second flap 94, and the round steel 10 can fall onto the guide platform 97 on the other side. In this way, the round steel 10 can be diverted on both sides to improve the processing efficiency and orderly transmission.

[0063] The basic working principle of the present invention is as follows: the round steel 10 is placed on the feed rack 21. When the round steel 10 rolls down to the feed port, the tidying device pushes the two ends of the round steel 10 to be arranged so that the ends of several round steels 10 are flush. After the round steel 10 enters the furnace, the driving component 13 drives the movable bed 12 to move. When the movable bed 12 moves relative to the fixed bed 11, the round steel 10 in the furnace of the stepping furnace body 1 can be transferred to the discharge chamber 14 through the movable bed 12. When the movable bed 12 moves once, two round steels 10 can be transferred. When the movable bed 12 exits the discharge chamber 14, one round steel 10 is placed. One round steel 10 is placed on the large roller row, and the other round steel 10 is placed on the small roller row. When the first driving device drives the rotating shaft 31 to rotate, since the large V-shaped roller 313 and the small V-shaped roller 314 on the same rotating shaft 31 have the same rotation speed, and the diameter of the large V-shaped roller 313 at the contact surface with the round steel 10 is larger, and the diameter of the small V-shaped roller 314 at the contact surface with the round steel 10 is smaller, when the rotating shaft 31 rotates, the round steel 10 placed on the large roller row is transmitted out of the discharge chamber 14 first compared with the round steel 10 placed on the small roller row, and then the round steel 10 on the small roller row follows.

[0064] When the high-temperature heated round steel 10 is sent out from the discharge port and enters the arc-shaped transmission track 41, the second driving device is started, and the corresponding conical rollers 7 are driven to rotate. When the conical rollers 7 convey the round steel 10, the round steel 10 will generate centripetal force, and the side walls of the conical rollers 7 can provide horizontal supporting force for the round steel 10, so that the round steel 10 can be transmitted in the arc channel 413 in an arc shape with the center of the arc-shaped transmission track 41 as the center. The horizontal supporting force of the conical rollers 7 can prevent the round steel 10 from leaving the track due to the centripetal force during the transmission process. In this way, the round steels 10 are arranged by the tidying device during feeding, which has the effect of saving time and labor and convenient operation; when discharging, a large roller row and a small roller row are arranged in the discharging chamber 14, so that the two round steels 10 transmitted to the discharging chamber 14 through the moving bed 12 each time can be transmitted in sequence. In this way, compared with the prior art, it has the effect of speeding up transmission, increasing production, and saving energy consumption, and the tidy round steels 10 are orderly when the large and small roller rows are transmitted, and collision is not easy to occur; they are transmitted through the arc-shaped transmission track 41, and a turn and reversal are formed during the transmission process, which can reduce the overall length of the transmission, greatly reduce the required length of the factory building, have the effect of reducing the floor space, saving site resources, and effectively reducing costs.
