Description

Technical Field

[0002] The pusher type heating furnace is mainly composed of furnace body, heating system, pusher device, discharging device, temperature detection and control system, etc. The furnace body is generally rectangular, built with refractory materials into a furnace chamber, and supported and reinforced by a steel structure frame on the outside. The heating system includes burners, heating pipes, etc., which are responsible for providing heat to raise the temperature in the furnace to the temperature required for heating the steel billets. The pusher device is used to push the steel billets into the furnace one by one, and the discharging device takes the steel billets out of the furnace after heating is completed. The temperature detection and control system can monitor and control the temperature in the furnace in real time to ensure the heating quality of the steel billets.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 11As shown, the present invention provides an embodiment: an automatic feeding device for a push-steel heating furnace, comprising a device base 1, a heating furnace body 2 is fixedly installed on the top of the device base 1, a material storage box 3 and a support seat 4 are also fixedly connected to the top of the device base 1, a feeding assembly 5 is arranged on the device base 1 and the support seat 4, and the feeding assembly 5 includes a supporting mechanism 51, a pushing mechanism 53, a limiting mechanism 54, a loading mechanism 56 and a feeding mechanism 57, and the supporting mechanism 51, the pushing mechanism 53 and the limiting mechanism 54 are all provided in plurality;

[0037] The support mechanism 51 includes a fixed seat 511 fixedly connected to the inside of the support seat 4, two groups of eight support blocks 512 are symmetrically rotatably connected inside the fixed seat 511, a rack 513 is symmetrically slidably connected to the top of the fixed seat 511, and a positioning block 514 is symmetrically fixedly connected to the outer side of the rack 513;

[0038] The push mechanism 53 includes a slider 536 slidably connected to the inside of the fixed seat 511, a push block 539 is symmetrically fixedly connected to the outside of the slider 536, the push block 539 is slidably connected to the inside of the fixed seat 511, a connecting block 535 is fixedly connected to the inside of the slider 536, a push rod 531 is fixedly connected to the outside of the connecting block 535, a ball screw 537 is arranged inside the push rod 531, and a spiral pair transmission is formed between the push rod 531 and the ball screw 537;

[0039] The feeding mechanism 56 includes a movable seat 561 symmetrically slidably connected to the inside of the fixed seat 511, the movable seat 561 is internally rotatably connected to two movable blocks 563, the fixed seat 511 is internally rotatably connected to a bidirectional screw rod 564, a helical pair transmission is formed between the bidirectional screw rod 564 and the movable seat 561, the top of the bidirectional screw rod 564 is fixedly connected to a gear 562, and the gear 562 and the rack 513 are meshed with each other;

[0040] The limiting mechanism 54 is arranged inside the device base 1, the feeding mechanism 57 is arranged inside the storage box 3 and the support seat 4, the top of the support seat 4 is fixedly connected with the loading seat 52, the bottom of the storage box 3 is fixedly connected with the motor 2 55, the inside of the pushing mechanism 53 is rotatably connected with the driving shaft 58, and the output end of the motor 2 55 is fixedly connected to the driving shaft 58 through a coupling.

[0041] In practical application, the embodiment of the present invention is as follows: Figures 4 to 6 As shown, in the push mechanism 53, since the push rod 531 and the ball screw 537 form a spiral pair transmission, the rotation of the ball screw 537 pushes the push rod 531 to move, driving the connecting block 535 and the push block 539 outside the slider 536 to slide in the fixed seat 511, pushing the steel billet on the fixed seat 511 forward to achieve feeding;

[0042] At the same time, if Figure 5 , Figure 6 , Figure 8 and Fig.12 As shown, the push block 539 pushes the rack 513 under the obstruction of the positioning block 514. As the rack 513 moves with the feeding of the steel billet, the gear 562 in the feeding mechanism 56 meshing with the rack 513 rotates, driving the bidirectional screw rod 564 to rotate. Since the bidirectional screw rod 564 and the movable seat 561 are driven by a spiral pair, the movable seat 561 slides symmetrically in the fixed seat 511, thereby driving the movable block 563 to move. During the feeding process, the movable seat 561 moves downward to drive the movable block 563 to move to the bottom of the next steel billet. When the push rod 531 returns, the movable block 563 moves upward to lift the new steel billet to the fixed seat 511, thereby realizing the feeding cycle of the steel billet.

[0043] In addition, if Figure 2 , Figure 3 and Fig. 9 As shown, the limiting mechanism 54 and the feeding mechanism 57 work together. The limiting mechanism 54 can limit the billet during the billet feeding process to ensure that the billet feeding position is accurate; the feeding mechanism 57 can feed the billets in the storage box 3 into the support seat 4 in sequence, and under the action of the limiting mechanism 54, the billets are separated to ensure that each billet is located directly below the fixed seat 511, so that the feeding mechanism 56 can feed the billets continuously and efficiently, thereby ensuring the overall feeding cycle efficiency and providing a stable and continuous billet feeding process for the heating furnace body 2.

[0044] like Figures 3 to 7 As shown, the pushing mechanism 53 also includes a fixed block 533 fixedly connected to the support seat 4, a motor 534 is fixedly installed on the top of the fixed block 533, the output end of the motor 534 is fixedly connected to the ball screw 537 through a coupling, the top of the fixed block 533 is fixedly connected to a limit ring 538, the ball screw 537 is rotatably connected between the fixed block 533 and the limit ring 538, the top of the support seat 4 is fixedly connected to a guide seat 532, and the push rod 531 is slidably connected to the inside of the guide seat 532.

[0045] In actual application of the embodiment of the present invention, when a pushing operation is required, the motor 534 installed on the fixed block 533 fixedly connected to the support seat 4 is started, and the output end of the motor 534 drives the ball screw 537 to rotate between the fixed block 533 and the limit ring 538 with the help of a coupling. Since a spiral pair transmission is formed between the push rod 531 and the ball screw 537, and the push rod 531 is slidably connected to the inside of the guide seat 532, under the rotation of the ball screw 537, the push rod 531 moves linearly along the guide direction of the guide seat 532, and then pushes the connection block 535 and the push block 539 on the outside of the slider 536 to slide in the fixed seat 511, and pushes the steel billet located on the fixed seat 511 toward the heating furnace body 2, thereby realizing the feeding process of the steel billet.

[0046] like Fig. 9 and Fig.10 As shown, the limiting mechanism 54 includes a cylinder 541 fixedly connected to the inside of the device base 1, a piston 1 544 and a piston 2 547 are slidably connected inside the cylinder 541, a connecting rod 1 543 is fixedly connected to the top of the piston 1 544, a pressure block 542 is fixedly connected to the top of the connecting rod 1 543, a spring 548 is symmetrically fixedly connected between the piston 1 544 and the inner wall of the cylinder 541, a connecting rod 2 546 is fixedly connected to the top of the piston 2 547, and a limiting block 545 is fixedly connected to the top of the connecting rod 2 546.

[0047] In actual application of the embodiment of the present invention, when the steel billet moves to the top of the limiting mechanism 54, the steel billet first contacts the pressure block 542 and applies downward pressure to the pressure block 542. After the pressure block 542 is subjected to the force, it pushes the piston 1 544 to slide downward in the cylinder 541 through the connecting rod 1 543. At this time, the spring 548 is compressed to store elastic potential energy. During the downward movement of the piston 1 544, the pressure change in the cylinder 541 will push the piston 2 547 to move upward. The piston 2 547 drives the limiting block 545 to rise through the connecting rod 2 546, thereby realizing the limiting effect on the steel billet, ensuring the position accuracy of the steel billet during the feeding process, preventing it from being offset or misplaced, providing a stable material basis for the subsequent feeding and heating processes, and ensuring the efficient and accurate operation of the automatic feeding device of the heating furnace body 2.

[0048] like Fig.12 As shown, the support mechanism 51 also includes a fixed shaft 516 rotatably connected to the inside of the support block 512 , both ends of the fixed shaft 516 are fixedly connected to the fixed seat 511 , and a torsion spring 515 is fixedly connected between the fixed shaft 516 and the support block 512 .

[0049] When the embodiment of the present invention is actually used, the steel billet will push the support block 512 to rotate during the upward movement, and drive the torsion spring 515 to store elastic potential energy. When the steel billet moves to the top, the support block 512 is reset under the elastic action to support the steel billet, ensuring that the steel billet is stably supported on the top of the fixed seat 511.

[0050] like Fig. 9 and Fig.11 As shown, the feeding mechanism 57 includes a feeding belt 571, and the support seat 4 and the storage box 3 are rotatably connected to the inside thereof with a transmission wheel 572, the feeding belt 571 is transmission-connected to the two transmission wheels 572, and the driving shaft 58 is fixedly connected to the transmission wheel 572 located in the storage box 3.

[0051] When the embodiment of the present invention is actually applied, the motor 2 55 is started and the power is transmitted to the drive shaft 58 through the coupling, so that the drive shaft 58 drives the transmission wheel 572, and the transmission wheel 572 drives the feeding belt 571 to realize the loading of the steel billet, so as to cooperate with the limiting mechanism 54 to ensure the stability and continuity of the loading.
