[0003] The existing equipment for processing obtuse angles of round steel mostly utilizes a coil to heat the two ends of the round steel first when processing the obtuse angles of round steel, and then utilizes an obtuse angle mold to perform hot obtuse angle forming on the round steel after heating.

[0036] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0037] like Figure 1-Figure 8As shown, an integrated device for round steel obtuse angle includes a frame 100, a heating component 200, a forming component 300 and a conveying component 400. The heating component 200 is arranged on the frame 100, the heating component 200 is used to heat both ends of the round steel 1000, the forming component 300 is used to simultaneously form the two ends of the heated round steel 1000 with the same amount of kinetic energy, and the conveying component 400 is used to convey the round steel 1000 to the location of the heating component 200.

[0038] When in use, the staff transports the round steel 1000 to the location of the heating component 200 through the conveying component 400, and heats the two ends of the round steel 1000 through the heating component 200, so that the two ends of the round steel 1000 are heated to a preset temperature. Next, the staff moves the round steel 1000 from the location of the heating component 200 to the location of the forming component 300, and performs obtuse angle forming on the two ends of the round steel 1000 through the forming component 300, and processes the two ends of the round steel 1000 into an obtuse angle shape. Since the forming component 300 uses the same amount of kinetic energy to heat the heated round steel The two ends of the round steel 1000 are formed at the same time, so the deformation degree caused by the force on the two ends of the heated round steel 1000 is the same, which makes the physical strength of the obtuse angles at both ends of the round steel 1000 basically the same. In addition, since the forming component 300 forms the two ends of the round steel 1000 at the same time, the forces on the two ends of the round steel 1000 are the same in magnitude and opposite in direction during the forming process, which means that the round steel 1000 will not be positionally shifted during the forming process. Therefore, the physical dimensions of the obtuse angles at both ends of the round steel 1000 can be exactly the same, which is conducive to the standardized production of batch round steel 1000.

[0039] It should also be added that the device can simultaneously perform obtuse angle forming on both ends of the round steel 1000, which has higher processing efficiency.

[0040] In a further embodiment, Figure 1 , Figure 2 and Figure 7As shown, the forming assembly 300 includes a forming mold 310, a distance measuring module 320, a speed-changing drive module 330 and a controller. There are two forming molds 310 and they are arranged horizontally at intervals on the frame 100. The forming surface of the forming mold 310 is processed inwardly with a conical ring groove, which is used to squeeze the two ends of the round steel 1000 through the conical ring groove to process the two ends of the round steel 1000 into obtuse angles. The two forming molds 310 can be close to each other or away from each other. The distance measuring module 320 is arranged on the inner side of the forming mold 310, and is used to detect the distance between the two ends of the round steel 1000 and the forming mold 310 on the corresponding side. The speed-changing drive module 330 0 is arranged on the frame 100, the variable speed drive module 330 is used to drive the two forming dies 310 to approach or move away from each other and to adjust the speed of the two forming dies 310 when they approach each other, and the controller is configured to receive the distances between the two ends of the round steel 1000 and the forming dies 310 on the corresponding side measured by the distance measuring module 320, and adjust the speed of the two forming dies 310 when they approach each other according to the distances between the two ends of the round steel 1000 and the forming dies 310 on the corresponding side measured by the distance measuring module 320, so that the speed values ​​of the two forming dies 310 when they contact the end surfaces of the two ends of the round steel 1000 are the same.

[0041] Since the round steel 1000 is prone to move along its axial direction during the process of moving from the location of the heating component 200 to the location of the forming component 300, this will cause different distances between the end faces of the round steel 1000 and the forming mold 310 on the corresponding side. Therefore, it is necessary to measure the distance between the end faces of the round steel 1000 and the forming mold 310 on the corresponding side through the distance measuring module 320, and then the controller matches different accelerations according to the distance measured by the distance measuring module 320, so that the acceleration of the forming mold 310 on the side with a smaller distance is greater than the acceleration of the forming mold 310 on the side with a larger distance, so that the speed values ​​of the two end faces of the round steel 1000 when contacting the forming mold 310 on the corresponding side can be the same, which also enables the two forming molds 310 to stamp the end faces of the round steel 1000 with the same kinetic energy, so that the obtuse angle physical strengths at both ends of the round steel 1000 are basically the same.

[0042] It is understandable that if Figure 8 As shown, the final speed of the two molding dies 310 The time taken for the two forming dies 310 to contact the round steel 1000 is the preset value, the smaller side spacing The distance between the larger side is the measured value, and the unknown number to be determined is the acceleration of the molding die 310 on the side with the smaller spacing. , and the acceleration of the molding die 310 on the side with the larger spacing , and the molding die 310 speed on the side with larger spacing reaches Time required For the side with smaller spacing, the distance moved by the molding die 310 is , from which the acceleration of the molding die 310 on the side with the smaller spacing can be calculated For the side with a larger spacing, the distance that the molding die 310 moves is , from which we can calculate ,Will Substitution , we can find Next, the controller only needs to control the variable speed drive module 330 on the side with the smaller spacing. The acceleration is uniformly accelerated, and the variable speed drive module 330 on the side with a larger spacing is controlled by the controller at the same time. The acceleration of uniform acceleration duration, then keep The two forming dies 310 continue to move at a speed of , so that the speed values ​​when the two forming dies 310 contact the end surfaces of the round steel 1000 are the same.

[0043] It should be further explained that the distance measuring module 320 is a distance measuring sensor, specifically, it can be any one of an ultrasonic distance measuring sensor, a laser distance measuring sensor or a near infrared distance measuring sensor.

[0044] In a further embodiment, Figure 2 As shown, the variable speed drive module 330 includes a toothed plate 331, a gear 332, a connecting column 333, a conical pulley 334, a linear electric cylinder 335, a driving pulley 336 and a tensioning wheel 337. One end of the toothed plate 331 is fixedly connected to the molding die 310 and the toothed plate 331 is slidably connected to the frame 100. The gear 332 is meshed with the toothed plate 331. The gear 332 is coaxially fixedly connected to the connecting column 333. The gear 332 and the connecting column 333 can rotate synchronously and move relatively along the axis of the connecting column 333. The connecting column 333 The end away from the gear 332 is coaxially fixedly connected with the conical pulley 334. The linear electric cylinder 335 is arranged on the frame 100. The telescopic end of the linear electric cylinder 335 and the conical pulley 334 can move synchronously and rotate relatively. The frame 100 is also provided with a driving motor 338. The output end of the driving motor 338 is coaxially fixedly connected with the driving pulley 336. The driving pulley 336 and the conical pulley 334 are connected by a belt 339. The frame 100 is also provided with a tensioning wheel 337, which is in transmission connection with the belt 339.

[0045] During use, when the molding die 310 needs to move at a constant speed, the controller controls the drive motor 338 to start, the output shaft of the drive motor 338 drives the drive pulley 336 to rotate, the drive pulley 336 drives the conical pulley 334 to rotate through the belt 339, the conical pulley 334 drives the connecting column 333 to rotate, the connecting column 333 drives the gear 332 to rotate, the gear 332 drives the tooth plate 331 to move, and the tooth plate 331 drives the molding die 310 to move synchronously at a constant speed; when the molding die 310 needs to move at a constant acceleration, the controller simultaneously controls the telescopic end of the linear electric cylinder 335 to move at a constant speed Contraction, so that the contracted end of the linear electric cylinder 335 drives the conical pulley 334 to move away from the connecting column 333 at a uniform speed. At this time, one end of the friction transmission between the belt 339 and the conical pulley 334 moves along the outer circumference of the conical pulley 334 toward the side of the small cross-sectional size of the conical pulley 334. At this time, the angular velocity of the conical pulley 334 increases at a uniform speed. The increase in the angular velocity of the conical pulley 334 increases the angular velocity of the gear 332. The meshing of the gear 332 and the tooth plate 331 increases the moving speed of the tooth plate 331 at a uniform speed. The tooth plate 331 drives the molding mold 310 to uniformly accelerate linear motion.

[0046] It should also be noted that, in order to enable the gear 332 and the connecting column 333 to rotate synchronously and move relatively along the axis of the connecting column 333, specifically, the gear 332 and the connecting column 333 can be connected in the form of a spline structure.

[0047] It should also be noted that in order to enable the tensioning wheel 337 to tension the belt 339, specifically, an elastic support frame is provided on the frame 100, and the elastic support frame includes a lower support frame and an upper support frame, and the lower support frame and the upper support frame are connected by a spring so that the length of the elastic support frame can be telescopically changed, and the tensioning wheel 337 is arranged on the side of the upper support frame away from the spring.

[0048] It should also be noted that the belt 339 is a transmission belt with a circular cross-section, so that the belt 339 is evenly stressed.

[0049] It should be additionally explained that a limiting groove 112 is provided on the side beam frame 110 , and the tooth plate 331 is slidably connected in the limiting groove 112 . The limiting groove 112 is used to limit the tooth plate 331 to prevent the tooth plate 331 from sliding forward and backward.

[0050] In a further embodiment, Figure 3 As shown, the frame 100 includes a side beam frame 110 and a curved material guide plate 120 . There are two side beam frames 110 and they are horizontally spaced apart. The curved material guide plate 120 is located between the two side beam frames 110 and is fixedly connected to the top of the side beam frames 110 .

[0051] The function of the curved guide plate 120 is to enable the round steel 1000 thereon to roll from the location of the heating assembly 200 to the location of the forming assembly 300 under the action of the round steel 1000's own gravity through the change in the height of its curved surface. The side beam frame 110 is used to support both sides of the curved guide plate 120.

[0052] In a further embodiment, Figure 5 As shown, the curved material guide plate 120 is provided with a first groove 121, and a first stop plate 122 is slidably connected in the first groove 121. The first stop plate 122 can extend upward from the first groove 121 to a preset length. Specifically, a first hydraulic rod is provided inside the first groove 121, and the telescopic end of the first hydraulic rod is fixedly connected to the first stop plate 122. The controller is electrically connected to the first hydraulic rod. The first stop plate 122 stops the round steel moved to the position of the heating component 200, and limits its forward movement along the curved material guide plate 120.

[0053] When in use, before the heating component 200 heats the round steel 1000, the controller causes the first hydraulic rod to drive the first stop plate 122 to extend upward, so that the height of the first stop plate 122 is higher than the curved material guide plate 120. At this time, after the round steel 1000 rolls down from the curved material guide plate 120, it will stop at the position of the heating component 200 under the stopping action of the first stop plate 122, so that the heating component 200 can heat both ends of the round steel 1000.

[0054] In a further embodiment, Figure 1 and Figure 4 As shown, the heating assembly 200 includes a heating platform 210 and a heating coil module 220. There are two heating platforms 210, which are slidably disposed on the side beam frame 110 respectively. The two heating platforms 210 can be close to or away from each other, and the heating coil module 220 is disposed on the heating platform 210.

[0055] After the round steel 1000 is stopped and limited by the first stop plate 122, the two heating platforms 210 are moved closer to each other, and the two heating platforms 210 drive the heating coil module 220 to move until the heating coil module 220 gradually surrounds the two ends of the round steel 1000. At this time, the heating coil module 220 is energized, and under the action of eddy currents, the two ends of the round steel 1000 are rapidly heated to a preset temperature.

[0056] It should also be noted that, in order to enable the two heating tables 210 to approach each other or move away from each other, specifically, a second hydraulic rod is provided on the side beam frame 110, and a slide groove 111 is also provided on the side beam frame 110. The telescopic end of the second hydraulic rod is fixedly connected to the heating table 210, and the axis of the second hydraulic rod moves along the extension direction of the slide groove 111, thereby driving the heating table 210 to move, so that the two heating tables 210 can approach each other or move away from each other.

[0057] In a further embodiment, Figure 1 As shown, the conveying assembly 400 includes a lifting conveyor 410 and a machine base 420. The lifting conveyor 410 is arranged on the machine base 420, and partitions 430 are arranged at equal intervals on the conveyor belt of the lifting conveyor 410.

[0058] When in use, the controller controls the lifting conveyor 410 to start, and the lifting conveyor 410 makes its conveyor belt rotate counterclockwise. Under the action of the partition 430, the round steel 1000 located on the partition 430 moves synchronously with the partition 430, so that the lifting conveyor 410 transports the batch-stacked round steel 1000 to the curved material guide plate 120.

[0059] It should also be noted that the conveyor belt of the lifting conveyor 410 is a soft steel belt, and the partition 430 is also made of soft steel. This is to enhance the load-bearing capacity of the partition 430 and prevent the partition 430 from tilting downward due to the small load-bearing capacity of the partition 430, thereby causing the round steel 1000 on the partition 430 to roll off.

[0060] In a further embodiment, Figure 1 As shown, the integrated equipment for round steel obtuse angles includes a stacking table 500, which is used to stack the round steels and to disperse the round steels one by one on each partition 430.

[0061] In a further embodiment, Figure 1 and Figure 5 As shown, a flip plate 600 is provided between the two side beam frames 110 , and the flip plate 600 can be rotated to the front of the forming assembly 300 to stop the round steel moved to the position of the forming assembly 300 , limiting its forward movement along the curved guide plate 120 .

[0062] Before the forming assembly 300 forms the round steel 1000, the controller controls the flip plate 600 to rotate to the front position of the forming assembly 300, and then the controller causes the first stop plate 122 to move downward, and the heated round steel 1000 rolls to the position of the forming assembly 300, and is limited at the position of the forming assembly 300 under the action of the flip plate 600, and then the forming assembly 300 can perform forming processing on the round steel 1000. After the forming processing, the flip plate 600 is rotated to the top of the forming assembly 300, and the flip plate 600 no longer limits the round steel 1000, and the round steel 1000 rolls forward to be away from the forming assembly 300 under the action of its own gravity.

[0063] In a further embodiment, Figure 1 As shown, the integrated equipment for round steel obtuse angles includes a discharge guide plate 700, and the upper end surface of the discharge guide plate 700 is a downwardly inclined curved surface.

[0064] The unloading guide plate 700 is provided to guide the round steel 1000 rolling forward from the position of the forming assembly 300 to prevent the surface of the round steel 1000 from being deformed during the rolling process.

[0065] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
