Description

Technical Field

[0001] The utility model relates to an automatic feeding device for a seamless steel pipe heating furnace, belonging to the technical field of seamless steel pipe production equipment. Background Art

[0002] A seamless steel pipe heating furnace is a heat treatment device used to heat seamless steel pipe blanks or billets. It is typically used in the steel pipe manufacturing process, such as heating before hot rolling or cold drawing. Currently, seamless steel pipes are typically fed using simple conveying mechanisms with a single function. When the seamless steel pipes are transported on the conveying mechanism, it is necessary to select the appropriate conveying mechanism based on the different seamless steel pipes, which reduces overall processing efficiency. After searching, it was found that Chinese patent No. CN214494811U discloses an automatic feeding device for seamless steel pipe production. In this patent, when the steel pipe needs to be fed, the height of the center of the material is adjusted by adjusting the height of the pneumatic telescopic rod. The hinge shaft motor drives the hinge shaft to drive the push plate to rotate to the rear end of the material, and the material is placed on the feeding plate (the feeding plate is an angle iron). The sprocket motor drives the active sprocket to rotate, causing the two transmission chains to rotate simultaneously. The push plate pushes the material forward along the feeding plate, completing the feeding process. However, in this patent, the steel pipe is placed on the loading plate and pushed by the push plate, which will cause certain wear on the surface of the steel pipe. When pushing a large-diameter steel pipe, the pushing efficiency will be reduced due to the friction between the steel pipe and the loading plate. Summary of the Invention

[0030] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0031] like Figure 1-7 As shown, an automatic feeding device for a seamless steel pipe heating furnace comprises:

[0032] Rack 1;

[0033] A first conveying component, the first conveying component includes a plurality of first rollers 2, and the first rollers 2 are rotatably mounted on the frame 1;

[0034] The second conveying component includes a fixed conveying assembly and a movable conveying assembly. The fixed conveying assembly includes a first conveying bracket 311, a first conveying wheel 312, a second conveying wheel 313 and a first conveyor belt 314. The first conveying bracket 311 is mounted on the frame 1. The first conveying wheel 312 and the second conveying wheel 313 are rotatably mounted on the first conveying bracket 311. The first conveyor belt 314 is suitable for connecting the first conveying wheel 312 and the second conveying wheel 313.

[0035] The movable conveying assembly includes a second conveying bracket 321, a third conveying wheel 322, a fourth conveying wheel 323 and a second conveying belt 324. The second conveying bracket 321 is slidably mounted on the first roller 2. The third conveying wheel 322 and the fourth conveying wheel 323 are rotatably mounted on the second conveying bracket 321. The second conveying belt 324 is adapted to connect the third conveying wheel 322 and the fourth conveying wheel 323.

[0036] A conveying channel 33 is provided between the first conveyor belt 314 and the second conveyor belt 324 . The second conveying bracket 321 is adapted to move on the first roller 2 through an adjustment component, thereby changing the width of the conveying channel 33 to accommodate seamless steel pipes of different sizes.

[0037] Specifically, if Figure 1-5 As shown, the adjustment assembly includes at least one screw-nut pair, which includes a screw 41 rotatably mounted on the frame 1 and a nut mounted on the second conveying bracket 321 . The screw 41 is rotated to drive the second conveying bracket 321 to move on the first roller 2 .

[0038] Specifically, if Figure 1-5 As shown, the adjustment assembly further includes an adjustment handwheel 42 , which is mounted on the lead screw 41 .

[0039] In this embodiment, the adjustment handwheel 42 is connected to the screw 41. When the adjustment handwheel 42 is turned, the screw 41 rotates accordingly. Since the screw 41 cooperates with the nut, rotating the screw 41 causes the nut to move along the axis of the screw. Since the nut is mounted on the second conveying bracket 321, the movement of the nut drives the second conveying bracket to move axially on the first roller 2 along the first roller 2.

[0040] Specifically, if Figure 5-7 As shown, the automatic loading device of the seamless steel pipe heating furnace also includes a driving assembly, which includes a driving motor 51, a driving gear 52, a first driven gear 53, a second driven gear 54 and a synchronous chain 55. The driving gear 52 is connected to the movable end of the driving motor 51, the first driven gear 53 is coaxially arranged with the second conveying wheel 313, the second driven gear 54 is coaxially arranged with the fourth conveying wheel 323, and the synchronous chain 55 is suitable for connecting the driving gear 52, the first driven gear 53 and the second driven gear 54.

[0041] In this embodiment, the driving motor 51 drives the driving gear 52 to rotate counterclockwise. Since the synchronous chain 55 is connected to the driving gear 52, the first driven gear 53 and the second driven gear 54, the first driven gear 53 also rotates counterclockwise. The synchronous chain 55 is not completely wound around the second driven gear 54, and the synchronous chain 55 drives the second driven gear 54 to rotate clockwise.

[0042] Because the first driven gear 53 is coaxially arranged with the second conveyor wheel 313, and the second driven gear 54 is coaxially arranged with the fourth conveyor wheel 323, the second conveyor wheel 313 drives the first conveyor belt 314 to move toward the entrance of the heating furnace, and the fourth conveyor wheel drives the second conveyor belt 324 to move toward the entrance of the heating furnace. The first conveyor belt 314 and the second conveyor belt 324 are in contact with the seamless steel pipe to be loaded, and the seamless steel pipe is driven to move toward the entrance of the heating furnace by the friction force of the first conveyor belt 314 and the second conveyor belt 324.

[0043] Specifically, if Figure 5-7 As shown, the automatic loading device of the seamless steel pipe heating furnace also includes a first tensioning assembly, which includes a tensioning bracket 61 and two tensioning gears 62. The tensioning bracket 61 is installed on the frame 1, and the tensioning gear 62 is installed on the tensioning bracket 61 and abuts against the synchronous chain 55.

[0044] Specifically, if Figure 5-6 As shown, the tensioning bracket 61 is provided with two waist holes 611 , and the two tensioning gears 62 are movably installed in the corresponding two waist holes 611 .

[0045] In this embodiment, the two tensioning gears 62 are installed in the corresponding two waist holes 611 through two fastening nuts. Loosening the fastening nuts allows the tensioning gears 62 to move along the waist holes 611, so that the two tensioning gears 62 move toward or away from each other, and the contact pressure with the synchronization chain 55 changes, thereby changing the tensioning state of the chain, ensuring that the chain maintains appropriate tension, preventing increased wear, and affecting the transmission efficiency and service life of the chain.

[0046] Specifically, if Figure 5 As shown, the second conveying component also includes a second tensioning assembly and a third tensioning assembly. The second tensioning assembly includes a first tensioning wheel 71, and the third tensioning assembly includes a second tensioning wheel 72. The first tensioning wheel 71 is movably mounted on the first conveying bracket 311, and the second tensioning wheel 72 is movably mounted on the second conveying bracket 321.

[0047] Specifically, if Figure 5 As shown, the second tensioning assembly further includes a first tensioning adjustment device, which includes a first adjustment base 731, a first guide rail slider pair, and a first adjustment handle 732. The first adjustment base 731 is mounted on the first conveying bracket 311. The first guide rail slider pair includes a first guide rail and a first slider. The first guide rail is mounted on the first adjustment base 731. The first slider is connected to the first tensioning wheel 71. The first adjustment handle 732 is connected to the first slider.

[0048] The third tensioning assembly also includes a second tensioning adjustment device, which includes a second adjustment base 741, a second guide rail slider pair and a second adjustment handle 742. The second adjustment base 741 is installed on the second conveying bracket 321. The second guide rail slider pair includes a second guide rail and a second slider. The second guide rail is installed on the second adjustment base 741. The second slider is connected to the second tensioning wheel 72. The second adjustment handle 742 is connected to the second slider.

[0049] In this embodiment, the first slider is driven to slide along the first guide rail by gripping the first adjustment handle 732. Since the first slider is connected to the first tensioning wheel 71, when the first slider moves, it drives the first tensioning wheel 71 to move along the direction of the first guide rail, thereby changing the tension state of the first conveyor belt 314.

[0050] By holding the second adjustment handle 742, the second slider is driven to slide along the second guide rail. Since the second slider is connected to the second tensioning wheel 72, when the second slider moves, it drives the second tensioning wheel 72 to move along the direction of the second guide rail, thereby changing the tension state of the second conveyor belt 324.

[0051] Specifically, if Figure 1-4 As shown, at least four universal movable wheels 8 are also installed at the bottom of the frame 1.

[0052] Specifically, if Figure 4 As shown, a connecting bracket 9 is also installed on one side of the frame 1, and the connecting bracket 9 is suitable for connecting to an external heating furnace.

[0053] In this embodiment, the universal movable wheel 8 allows the operator to easily push the equipment to the designated location or within the working area. When the automatic loading device is moved into position, it is connected to the external heating furnace and other equipment through the connecting bracket, ensuring the continuity and efficiency of the production process.

[0054] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
