Description

Technical Field

[0001] The present invention relates to the technical field of induction heating furnaces, and in particular to a feeding and transferring device and method for an induction heating furnace. Background Art

[0002] Hot forging, also known as hot die forging or hot forging, is a forging process performed in a high temperature environment above the metal recrystallization temperature. The process mainly includes three stages: preheating, forging and cooling. In the preheating stage, induction heating furnace has become the mainstream equipment for pre-forging heating.

[0003] The current induction heating furnace's feed conveyor has poor flexibility when conveying billets and cannot adapt to the transmission of billets of different specifications and sizes. When conveying billets of different specifications and sizes, the conveyor needs to be interrupted and the production line needs to be adjusted. The process is cumbersome and the production efficiency is low. At the same time, frequent adjustments to the production line lead to poor feeding stability and continuity, resulting in inconsistent heating time of the billets in the induction heating furnace, resulting in inconsistent temperature of the billets when they are taken out of the induction heating furnace, which often causes the billets to be scrapped due to overburning at high temperature.

[0004] Therefore, we propose an induction heating furnace feeding and conveying device and method. Summary of the invention

[0033] In this article, terms such as "left, right, up, down, front, and back" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they cannot be understood as absolute limitations on the scope of protection.

[0034] See also Figures 1 to 8The present embodiment provides a feeding and conveying device for an induction heating furnace, comprising two relatively parallel mounting plates 14, the upper end of which is fixedly provided with a center distance adjustment mechanism, which is used to adjust the center distance between the upper feeding wheel 13 and the lower feeding wheel 7. The lower end of the mounting plate 14 is provided with a driving mechanism, which is used to drive the upper feeding wheel 13 and the lower feeding wheel 7 to rotate. The lower end of the mounting plate 14 is provided with a supporting mechanism, which is used to support the blank 26.

[0035] Specifically, the center distance adjustment mechanism includes a first driving component, which includes a pressing cylinder 16. Cylinder side ear shafts 19 are fixed on both sides of the pressing cylinder 16. The cylinder side ear shafts 19 are rotatably installed on the cylinder fixing plate 18. The cylinder fixing plate 18 is welded and fixed to the upper end of the mounting plate 14. The pressing cylinder 16 can rotate on the cylinder fixing plate 18 through the cylinder side ear shafts 19. The upper roller rotates to drive the crank arm 15 to make an arc motion when the crank swing arm shaft 8 rotates. The piston rod of the pressing cylinder 16 needs to swing in a small range with the rotation of the upper roller crank arm 15. The pressing cylinder 16 rotates on the cylinder fixing plate 18 through the cylinder side ear shafts 19 to meet the demand for piston rod swinging.

[0036] Specifically, the output end of the pressing cylinder 16 is fixedly connected to a cylinder connector 20, and the end of the cylinder connector 20 away from the pressing cylinder 16 is hinged to the upper roller rotation driving crank arm 15, and the end of the upper roller rotation driving crank arm 15 away from the pressing cylinder 16 is fixedly connected to a crank swing arm shaft 8, and the crank swing arm shaft 8 is rotatably arranged on two mounting fixed plates 14 through bearings 24, and an upper roller pressing force arm 12 is fixedly arranged on the crank swing arm shaft 8, and a certain angle is formed between the upper roller pressing force arm 12 and the upper roller rotation driving crank arm 15, and the angle formed between the upper roller pressing force arm 12 and the upper roller rotation driving crank arm 15 ranges from 45° to 75°. In the present embodiment, the angle formed between the upper roller pressing force arm 12 and the upper roller rotation driving crank arm 15 is 60°.

[0037] Specifically, during operation, the pressing cylinder 16 drives the upper roller rotation driving crank arm 15 to move. Since the upper roller rotation driving crank arm 15 and the crank swing arm shaft 8 are fixedly connected, the upper roller rotation driving crank arm 15 drives the crank swing arm shaft 8 to rotate on the mounting fixed plate 14. The upper roller pressing force arm 12 is fixedly connected to the crank swing arm shaft 8, and the crank swing arm shaft 8 rotates together with the crank swing arm shaft 8. The upper roller transmission shaft 11 and the upper feeding wheel 13 installed at the end of the upper roller pressing force arm 12 away from the crank swing arm shaft 8 also rotate together, thereby realizing the adjustment of the center distance between the upper feeding wheel 13 and the lower feeding wheel 7.

[0038] Specifically, the crank swing arm shaft 8 is a three-stage shaft, including a first shaft section 81, a second shaft section 82 and a third shaft section 83. The upper roller pressing force arm 12 is fixedly installed on the second shaft section 82, and the upper roller rotation driving crank arm 15 is fixedly installed on the third shaft section 83. The third shaft section 83 is provided with an arc groove 84 on the side away from the upper roller rotation driving crank arm 15, which expands the space and is conducive to the passage of blanks 26 of different specifications and sizes.

[0039] Specifically, the driving mechanism includes an input drive shaft 2, which is rotatably arranged on two mounting plates 14 through bearings 24, and both ends of the input drive shaft 2 extend outward through the mounting plates 14. One end of the input drive shaft 2 is keyed to a second drive member. In this embodiment, the second drive member is a reduction motor, which includes a transmission motor and a gear box (reducer). The reduction motor provides power for the rotation of the input drive shaft 2.

[0040] Specifically, a driving pinion 1 is fixedly provided at one end of the input drive shaft 2 away from the driving motor, and the driving pinion 1 is meshed with the transition gear 1 3 for transmission, and the transition gear 1 3 is meshed with the lower roller driving gear 5 and the transition gear 2 9 for transmission. In this embodiment, the transition gear 1 3 and the transition gear 2 9 use gears of the same specification. The transition gear 13 is rotatably mounted on one end of the mounting fixed shaft 4 through a bearing 24, and the mounting fixed shaft 4 is fixedly mounted on the mounting fixed plate 14. A lower roller bearing arm 21 is fixedly arranged on the mounting fixed shaft 4, and a sleeve 23 is fixedly mounted on the end of the lower roller bearing arm 21 away from the mounting fixed shaft 4, and a bearing 24 is fixedly mounted in the sleeve 23. The lower roller transmission shaft 6 is rotatably connected to the end of the lower roller bearing arm 21 away from the mounting fixed shaft 4 through the bearing 24, and one end of the lower roller transmission shaft 6 is key-connected with the lower roller driving gear 5, and the other end of the lower roller transmission shaft 6 is fixedly connected with the lower feeding wheel 7. The transition gear 29 is rotatably mounted on one end of the crank swing arm shaft 8 through a bearing 24, and the transition gear 29 is meshed and transmitted with the upper roller driving gear 10. In this embodiment, the lower roller driving gear 5 and the upper roller driving gear 10 use gears of the same specification. The end of the upper roller transmission shaft 11 away from the upper feeding wheel 13 is key-connected with the upper roller driving gear 10.

[0041] Specifically, during operation, the reduction motor drives the input drive shaft 2 to rotate counterclockwise, the input drive shaft 2 drives the drive pinion 1 to rotate counterclockwise, the drive pinion 1 is meshed with the transition gear 3 for transmission, the transition gear 3 rotates clockwise with the installation fixed shaft 4 as the center, the lower roller drive gear 5 and the transition gear 2 9 are both meshed with the transition gear 3 for transmission, the lower roller drive gear 5 rotates counterclockwise, the lower roller drive gear 5 drives the lower roller drive shaft 6 and the lower feeding wheel 7 to rotate counterclockwise, the transition gear 2 9 rotates counterclockwise with the crank arm shaft 8 as the center, the upper roller drive gear 10 is meshed with the transition gear 2 9 for transmission, the upper roller drive gear 10 rotates clockwise, and the upper roller drive gear 10 drives the upper roller drive shaft 11 and the upper feeding wheel 13 to rotate clockwise.

[0042] Specifically, the supporting mechanism includes a feed support rotating wheel 17, which is fixedly mounted on the input drive shaft 2. When the reduction motor drives the input drive shaft 2 to rotate counterclockwise, the feed support rotating wheel 17 rotates counterclockwise along with the input drive shaft 2. When the blank 26 enters from the feeding direction, the feed support rotating wheel 17 can support the blank 26, and at the same time, the feed support rotating wheel 17 rotates to push the blank 26 forward.

[0043] Specifically, the upper feeding wheel 13, the lower feeding wheel 7 and the feed support rotating wheel 17 all include a steel inner ring 25 and a polyurethane rubber ring layer 22. The upper feeding wheel 13, the lower feeding wheel 7 and the feed support rotating wheel 17 all use the polyurethane rubber ring layer 22 as the outer ring, which plays a role in light weight. The polyurethane rubber ring layer 22 is sleeved on the outer peripheral surface of the steel inner ring 25. Usually, the blanks 26 shipped from the steel plant are all round bars, so the outer peripheral surface of the polyurethane rubber ring layer 22 is higher on both sides and lower in the middle, and the outer peripheral surface cross-section of the polyurethane rubber ring layer 22 is a semicircular arc structure, so that the upper feeding wheel 13, the lower feeding wheel 7 and the feed support rotating wheel 17 can match the blank 26, so that the upper feeding wheel 13 and the lower feeding wheel 7 can push the blank 26 to move forward stably through rotation and extrusion. The outer peripheral surface of the polyurethane rubber ring layer 22 is provided with grooves, which can increase the friction between the upper feeding wheel 13, the lower feeding wheel 7, the feed support rotating wheel 17 and the blank 26, making it easier for the upper feeding wheel 13, the lower feeding wheel 7 and the feed support rotating wheel 17 to push the blank 26 forward.

[0044] Specifically, the feeding device has a simple structure, low cost, easy maintenance, strong anti-interference ability, can effectively control the conveying process of the blank 26, has the characteristics of adjustable speed, precise feeding and stable output, and can accurately, stably and continuously convey blanks 26 of different specifications and sizes. The extruded billet 26 is fed forward stably by rotating the upper feeding wheel 13 and the lower feeding wheel 7. The center distance between the upper feeding wheel 13 and the lower feeding wheel 7 can be directly adjusted through the cooperation of the pressing cylinder 16, the upper roller rotation driving crank arm 15, the crank swing arm shaft 8 and the upper roller pressing force arm 12, so as to meet the transmission of billets 26 of various specifications and sizes, increase the flexible adjustment of the conveying device, so that when conveying billets 26 of different specifications and sizes, there is no need to interrupt the transmission and adjust the production line, simplify the process, and convey billets 26 of different specifications and sizes according to the rhythm required by the process, effectively ensuring the stability and continuity of the transmission of billets 26 of different specifications and sizes, and realizing the continuous production of billets 26 of different specifications and sizes. The heating time of the billets 26 in the induction heating furnace is consistent, and the furnace discharge temperature is consistent, thereby improving the production efficiency and the qualified rate of the billets 26.

[0045] Specifically, this embodiment further provides an induction heating furnace feeding and conveying method, the method using the above-mentioned induction heating furnace feeding and conveying device, comprising the following steps:

[0046] S1: When the blank 26 enters from the feeding direction, the feeding support rotating wheel 17 supports the entering portion of the blank 26, and at the same time, the feeding support rotating wheel 17 rotates to push the blank 26 to move forward.

[0047] S2: When the blank 26 moves to the position of the upper feeding wheel 13 and the lower feeding wheel 7, the upper feeding wheel 13 and the lower feeding wheel 7 rotate to extrude the blank 26, pushing the blank 26 to move forward, so that the blank 26 enters the induction heating furnace.

[0048] S3: After the blank 26 enters the induction heating furnace, the next blank 26 enters from the feeding direction. If the specifications of the next blank 26 are different from those of the previous blank 26, the pressing cylinder 16 drives the upper roller to rotate and drive the crank arm 15 to move. The upper roller rotates and drives the crank arm 15 to drive the crank swing arm shaft 8 to rotate. The upper roller pressing force arm 12, the upper roller transmission shaft 11 and the upper feeding wheel 13 rotate together with the crank swing arm shaft 8. The center distance between the upper feeding wheel 13 and the lower feeding wheel 7 changes until the center distance matches the specifications of the blank 26 that is about to enter.

[0049] S4: The blank 26 moves forward. When the blank 26 moves to the position of the upper feeding wheel 13 and the lower feeding wheel 7, the upper feeding wheel 13 and the lower feeding wheel 7 rotate to extrude the blank 26, pushing the blank 26 to move forward, so that the blank 26 enters the induction heating furnace, and then the next round of feeding begins.

[0050] The above embodiments are only to illustrate the basic principles and characteristics of the present invention, but are not limited to the above embodiments. It should be understood that for ordinary technicians in this field, various changes and modifications can be made to the present invention without departing from the spirit and scope of the present invention, and these changes and modifications fall within the scope of the present invention to be protected.
