Description

Technical Field

[0001] This application relates to the field of angle steel production technology, and in particular to an automated angle steel processing production line. Background Technology

[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an L-shape in cross-section. As a basic structural steel material, angle steel is widely used in numerous fields such as construction engineering, power transmission towers, bridges, machinery manufacturing, and warehouse racking due to its advantages of simple structure, good load-bearing capacity, and relatively low cost. Therefore, the production efficiency and product quality of angle steel directly affect the engineering quality, safety, and economic benefits of downstream industries.

[0003] Traditional angle steel production processes often rely on segmented operations and extensive manual labor. Typically, the production process is divided into multiple independent steps, such as billet heating, multi-pass rolling, length shearing, cooling, and collection. The transfer and connection of materials between these steps often require manual intervention, preventing the production line from achieving continuous and smooth automated operation. Significant waiting and material turnaround times create production bottlenecks, limiting overall output. Furthermore, the high frequency and intensity of manual operation make it difficult to meet the demands of large-scale, fast-paced modern production. Summary of the Invention

[0004] To improve production efficiency, this application provides an automated production line for angle steel processing.

[0005] The automated processing production line for angle steel provided in this application adopts the following technical solution:

[0006] An automated processing production line for angle steel includes a heating mechanism for heating the raw material;

[0007] The forming mechanism includes vertical and horizontal rolling mills arranged alternately along the rolling path, used to roll the stock into L-shaped angle steel from rectangular cross-section stock.

[0008] A shearing mechanism is used to cut the formed angle steel.

[0009] A cooling mechanism includes a support frame and a transfer assembly. The support frame supports angle steels so that multiple angle steels are spaced apart along the width direction of the support frame. The transfer assembly is used to intermittently transport the cut angle steels.

[0010] The flipping mechanism includes a support block and a first driving component. The support block comprises two interconnected blocks, both of which abut against the angle steel. When one block abuts against the angle steel, the other block is separated from it. The support block is rotatably connected to the support frame about an axis parallel to the length direction of the support frame. The first driving component drives the support block to rotate, thereby causing the support block to flip the angle steel.

[0011] By adopting the above technical solution, this application integrates the core processes of heating, forming, shearing, and cooling required for angle steel production into an organic whole. The billet automatically flows between various mechanisms, realizing continuous and automated production from billet to finished angle steel. This solution effectively solves the problems of poor process connection and long material turnover waiting time caused by traditional segmented operations, and eliminates the need for manual intervention between processes, thereby reducing labor intensity and improving overall production efficiency.

[0012] This solution also includes a flipping mechanism. When the angle steel is located on the bearing block, the first driving component drives the bearing block to rotate around the axis, which can smoothly drive the angle steel to flip. Since the included angle between the two blocks is an obtuse angle, the two blocks will not contact the angle steel at the same time. Therefore, during the cooling and conveying process, by completing the flipping action, all surfaces of the angle steel can fully contact the air, which helps to achieve more uniform and faster cooling, avoids internal stress and deformation caused by uneven cooling, and thus improves the final mechanical properties and straightness of the angle steel.

[0013] In addition, the flipping motion provides a slight vibration and impact to the angle steel, which helps to crack and peel off any loosely attached oxide scale. The detached oxide scale can fall directly into the gap below the cooling mechanism, rather than accumulating between the angle steel and the support surface. Furthermore, since the support block itself rotates periodically, even if a small amount of oxide scale falls onto its support surface, the next time it is flipped, this support surface will become the side or bottom surface, and the oxide scale on it will slide off due to gravity or inertia. This gives the support block a certain degree of self-cleaning ability, preventing a large accumulation of oxide scale at the support point, thereby ensuring the long-term stability of the contact state and heat transfer conditions between the angle steel and the support block.

[0014] Optionally, the vertical rolling mill is used to laterally roll the billet to control the leg height and leg width of the angle steel, and the horizontal rolling mill is used to planarly roll the billet to control the thickness of the angle steel.

[0015] By adopting the above technical solution, vertical and horizontal rolling mills are arranged alternately, which can control the plastic deformation of the billet in two directions. The vertical rolling mill is mainly responsible for the precise processing of the leg dimensions of the angle steel, such as leg height and leg width, while the horizontal rolling mill focuses on controlling the overall thickness of the angle steel. This collaborative operation method decomposes the complex forming task, which helps to achieve precise control of the cross-sectional dimensions of the angle steel, thereby improving the dimensional accuracy and forming quality of the final product.

[0016] Optionally, the vertical rolling mill includes a first frame, a rotating power component, a bidirectional lead screw, and a first bearing housing. There are two first bearing housings, and a vertical roll is rotatably connected to each first bearing housing. The first bearing housing is slidably connected to the first frame. The two ends of the bidirectional lead screw are threadedly connected to the two first bearing housings respectively. The rotating power component is used to drive the bidirectional lead screw to rotate so that the two first bearing housings slide in opposite directions.

[0017] By adopting the above technical solution, when the rotating power component drives the bidirectional lead screw to rotate, the two first bearing seats connected by threads will move synchronously and in opposite directions in a straight line. This structural design cleverly utilizes a single power source to achieve symmetrical adjustment of the two vertical rolls, which not only simplifies the transmission system but also ensures that the rolling centerline remains unchanged during the adjustment process. This facilitates the stable alignment of the billet during the rolling process and further improves the accuracy of the control of the leg height and leg width dimensions.

[0018] Optionally, the horizontal rolling mill includes a second frame, a second bearing housing, a third bearing housing, and a pressing assembly. The second bearing housing is slidably connected to the second frame, and horizontal rolls are rotatably connected to both the second and third bearing housings. The pressing assembly is connected to the second frame and is used to drive the second bearing housing to move and lock it.

[0019] By adopting the above technical solution, the second bearing seat is slidably adjustable, while the third bearing seat is relatively fixed. A specialized pressing assembly drives and locks the movable bearing seat, making the operation of the horizontal rolling mill more direct and convenient when adjusting the position of the upper roll to change the rolling thickness. The locking function provided by the pressing assembly ensures that the position of the upper roll remains stable under enormous rolling forces, thereby guaranteeing the uniformity and consistency of the angle steel thickness.

[0020] Optionally, the support frame includes a frame body and support rods disposed on the frame body. Multiple support rods are spaced apart along the length of the frame body, and the multiple support rods are arranged in parallel and spaced apart. The transfer assembly includes a bearing plate and a second driving component. Multiple bearing plates are provided, and the bearing plates and support rods are arranged in an alternating manner. The top wall of the bearing plate is used to support angle steel. The second driving component is used to drive the bearing plates to move along the height and width directions of the frame body.

[0021] By adopting the above technical solution, the bearing plate and support rod are arranged in an alternating manner, and the bearing plate is driven by the second driving component to move in the height and width directions, which can realize the step-by-step conveying of angle steel. This conveying method allows the angle steel to move intermittently laterally on the cooling bed, which not only ensures that the angle steel has sufficient time to contact the air for natural cooling during the movement, but also realizes the orderly arrangement and conveying of angle steel on the cooling bed, creating favorable conditions for the automated collection and sorting of subsequent processes, and improving the automation level of the cooling and conveying links.

[0022] Optionally, the cooling mechanism is provided in two sets, and the two sets of cooling mechanisms are arranged in parallel.

[0023] By adopting the above technical solution and setting up two sets of parallel cooling mechanisms, the capacity and processing capacity of the cooling area can be doubled. The production line can alternately or selectively distribute the angle steel to the two cooling beds as needed. This effectively avoids the problem that a single cooling bed becomes a production bottleneck because its processing speed cannot keep up with the output speed of the previous process. It is especially suitable for high-volume production needs and helps to improve the collaborative work capability and overall capacity of the entire production line.

[0024] Optionally, a guide mechanism is provided between the shearing mechanism and the cooling mechanism. The guide mechanism includes a main track, sub-tracks, and a deflection block. One end of the main track faces the shearing mechanism, and the other end of the main track is connected to the sub-tracks. Two sub-tracks are provided. The first sub-track leads to one group of cooling mechanisms, and the second sub-track leads to another group of cooling mechanisms. The deflection block is rotatably connected to the connection between the main track and the sub-tracks so that the main track is connected to one of the two sub-tracks.

[0025] By adopting the above technical solution, the rotating deflector block can flexibly guide the angle steel conveyed from the main track to either of the two sub-tracks. This structure achieves precise control and intelligent allocation of the angle steel flow direction, which is a prerequisite for the coordinated operation of the two cooling mechanisms. The automated system can control the deflector block according to the real-time occupancy of the cooling bed, efficiently allocating the angle steel to idle or more suitable cooling mechanisms, thereby realizing automated diversion of production materials and optimizing the production cycle.

[0026] Optionally, each of the two blocks is provided with a support member, which includes a support column and an elastic member. The support column is slidably inserted through the block, one end of which is used to abut against the angle steel, and the elastic member is connected between the block and the support column.

[0027] By adopting the above technical solution, before the bearing block begins to rotate, the top of the support column and the angle steel are in a spaced-out state. When the bearing block drives the angle steel to rotate at a small angle, the top of the support column will abut against the angle steel. As the angle steel rotates, the angle steel will gradually press down the top of the support column and stretch the elastic element. Therefore, the support column can support the angle steel during the rotation process, preventing the angle steel from moving laterally without rotating, thus ensuring the smooth progress of the angle steel rotation process. In addition, during the rotation process of the angle steel, one of the elastic elements will be stretched, thus providing elastic support for the angle steel and playing a certain buffering role, thereby protecting the angle steel and the rotation mechanism.

[0028] In summary, this application includes the following beneficial technical effects:

[0029] 1. Through integrated design, the heating, forming, shearing, cooling and flipping processes are integrated into one, realizing full automation of the angle steel production process. This solves the problems of low efficiency and high dependence on manual labor caused by traditional segmented production, improves production efficiency and reduces labor intensity.

[0030] 2. By adopting a combination of vertical and horizontal rolling mills, along with bidirectional screw symmetrical adjustment and independent pressing components, precise control of multiple dimensions such as leg height, leg width, and thickness of the angle steel is achieved, improving the product forming quality; by setting up a flipping mechanism, uniform cooling of the angle steel is promoted, improving the mechanical properties of the finished angle steel.

[0031] 3. By setting up a dual cooling mechanism and a turnout-type guiding mechanism, intelligent diversion of production materials and doubling of cooling capacity are achieved, solving the cooling bottleneck problem under high output, enhancing the flexibility and overall capacity of the production line, and making the whole line run more efficiently and smoothly.

Detailed Implementation

[0043] The following combination Figures 1-10 This application will be described in further detail.

[0044] This application discloses an automated angle steel processing production line. The function of this production line is to process rectangular cross-section blanks into L-shaped angle steels that meet specific specifications using a series of automated devices. (Refer to...) Figure 1The automated angle steel processing production line includes a heating mechanism 1, which uses a regenerative natural gas heater. Heating mechanism 1 is used to heat the billet at the beginning of the production process, bringing it to a plastic state suitable for rolling deformation. Once the billet is heated to the predetermined temperature, it automatically enters the subsequent forming mechanism 2.

[0045] The forming mechanism 2 is the core component that transforms the billet from a rectangular cross-section to an L-shaped cross-section. The forming mechanism 2 includes a vertical mill 21 and a horizontal mill 22 arranged alternately along the rolling direction. The vertical mill 21 and the horizontal mill 22 work together: when the billet passes through the vertical mill 21, a pair of vertical rolls 215 squeeze both sides of the billet (see reference). Figure 2 This process is mainly used to precisely control the leg height and leg width dimensions of the final angle steel; when the billet passes through the horizontal rolling mill 22, a pair of horizontal rolls 224 will roll the upper and lower surfaces of the billet (refer to...). Figure 3 This process is mainly used to precisely control the thickness of the angle steel's legs. This clearly defined and alternating rolling method allows for precise adjustment of the angle steel's cross-sectional dimensions, ensuring the quality of the forming process.

[0046] Reference Figure 2 To achieve precise adjustment of the rolling dimensions, the vertical rolling mill 21 includes a first frame 211, a rotating power component 212, a double-acting lead screw 213, and two first bearing seats 214. The two first bearing seats 214 can slide left and right on the first frame 211, and each first bearing seat 214 has a vertical roll 215 rotatably mounted on it. The double-acting lead screw 213 is horizontally positioned between the two first bearing seats 214, with one end having a left-hand thread and the other end having a right-hand thread. Both ends of the double-acting lead screw 213 are threaded into the two first bearing seats 214 respectively. The rotating power component 212 is a motor, which is fixedly mounted on the first frame 211. The double-acting lead screw 213 is coaxially connected to the output shaft of the rotating power component 212. During operation, the rotating power component 212 drives the bidirectional lead screw 213 to rotate, and the two first bearing seats 214 will slide synchronously, towards each other or away from each other because the threads rotate in opposite directions, thereby precisely and symmetrically adjusting the distance between the two vertical rolls 215, ensuring the stability of the rolling center line, and facilitating the improvement of the accuracy of angle steel leg size control.

[0047] Reference Figure 3The horizontal rolling mill 22 includes a second frame 221, a movable second bearing seat 222, a relatively fixed third bearing seat 223, and two sets of pressing assemblies 225. The second bearing seat 222 is located above the third bearing seat 223 and is vertically slidably connected to the second frame 221; the third bearing seat 223 is fixedly mounted on the second frame 221. Horizontal rolls 224 are rotatably connected to both the second bearing seat 222 and the third bearing seat 223. The pressing assemblies 225 are mounted on the top of the second frame 221, located at both ends of the second bearing seat 222. The pressing assemblies 225 can drive the second bearing seat 222 downward to reduce the roll spacing or upward to increase the spacing. After adjustment, the pressing assemblies 225 can also firmly lock the second bearing seat 222 in its current position to resist the huge rolling force and ensure the stability of the angle steel thickness during rolling.

[0048] Reference Figure 4 The pressing assembly 225 includes a first motor 2251, a worm gear 2252, a worm wheel 2253, and a screw 2254. The first motor 2251 is fixedly mounted on the second frame 221, and its output shaft is horizontally positioned and coaxially connected to the worm gear 2252. The screw 2254 is vertically positioned and rotatably connected to the second frame 221 around its own axis. The bottom end of the screw 2254 is threadedly connected to a slidingly positioned second bearing seat 222. The worm wheel 2253 is coaxially fixedly connected to the top end of the screw 2254 and meshes with the worm gear 2252. Therefore, after the first motor 2251 starts, it drives the worm 2252 to rotate, which in turn drives the worm wheel 2253 to rotate. The worm wheel 2253 then drives the screw 2254 to rotate, causing the second bearing seat 222 to move vertically, thereby adjusting the distance between the upper and lower horizontal rolls 224. The thread helix angle on the screw 2254 is less than the equivalent friction angle, thus giving the screw 2254 a self-locking capability. Furthermore, the worm wheel 2253 and the worm 2252 can achieve self-locking, further ensuring the stability of the second bearing seat 222 after its position is adjusted.

[0049] Reference Figure 1 The forming mechanism 2 is equipped with a shearing mechanism 3 at its end. After the angle steel is rolled into shape, the shearing mechanism 3 cuts the angle steel to a preset length. The shearing mechanism 3 uses a flying shear, which can cut the angle steel while it is moving, thus ensuring the continuity of the production process and guaranteeing work efficiency.

[0050] The flying shear machine consists of upper and lower blade holders, each equipped with shear blades that match the cross-sectional shape of the angle steel. Detection devices within the system, such as speed measuring wheels or laser velocimeters, monitor the speed of the angle steel being conveyed in real time. When shearing is required, the control system drives the blade holder's operating mechanism, accelerating the shear blades horizontally until their horizontal speed perfectly matches the angle steel's speed, achieving synchronous tracking. During this brief period of synchronous movement, the mechanism driving the blade holder's vertical movement quickly actuates, causing the upper and lower shear blades to close, completing the shearing of the angle steel. After the shearing action is complete, the shear blades quickly open and decelerate back to their initial position, awaiting the next shearing command. Through this series of high-speed, coordinated actions, the flying shear machine achieves precise, length-limited cutting of the angle steel without stopping its conveying. The flying shear machine is a device in the prior art; the illustration only shows its position relative to other components.

[0051] Reference Figure 1 and Figure 5 A cooling mechanism 4 is provided at the end of the shearing mechanism 3. The cut high-temperature angle steel is conveyed to the cooling mechanism 4 for cooling. The cooling mechanism 4 includes a large support frame 41 and a transfer assembly 42. The support frame 41 includes a frame body 411 and support rods 412 disposed on the frame body 411. The length direction of the frame body 411 is parallel to the conveying direction of the angle steel. The support rods 412 are arranged along the width direction of the frame body 411. Multiple support rods 412 are provided and are arranged parallel to each other at intervals along the length direction of the frame body 411. The top wall of the support rods 412 is used to support the angle steel.

[0052] Reference Figure 5 and Figure 6 The transfer assembly 42 is used to intermittently move the angle steel along the width direction of the frame 411. The transfer assembly 42 includes a support plate 421 and a second drive component 422. The support plate 421 is arranged parallel to the support rod 412, and the top wall of the support plate 421 is used to temporarily support the angle steel. Multiple support plates 421 are provided, and each support plate 421 is located between two adjacent support rods 412. The second drive component 422 is arranged below the support plate 421 and is used to drive the support plate 421 to move along the height and width directions of the frame 411.

[0053] Reference Figure 7The second driving component 422 includes a sliding seat 4221, a lifting frame 4222, a first hydraulic cylinder 4223, and a second hydraulic cylinder 4224. The sliding seat 4221 is slidably arranged along the width direction of the frame 411. The first hydraulic cylinder 4223 is horizontally arranged, and the end of the piston rod of the first hydraulic cylinder 4223 is connected to the sliding seat 4221, thus the first hydraulic cylinder 4223 can drive the sliding seat 4221 to slide horizontally. The lifting frame 4222 is vertically slidably connected to the top wall of the sliding seat 4221. The second hydraulic cylinder 4224 is vertically arranged, and the cylinder body of the second hydraulic cylinder 4224 is fixedly installed on the sliding seat 4221. The end of the piston rod of the second hydraulic cylinder 4224 is fixedly connected to the lifting frame 4222. The bearing plate 421 is fixedly installed on the top of the lifting frame 4222. The second hydraulic cylinder 4224 can drive the lifting frame 4222 and the bearing plate 421 to slide vertically. Therefore, with the cooperation of the first hydraulic cylinder 4223 and the second hydraulic cylinder 4224, the bearing plate 421 can move along the height direction and the width direction of the frame 411 respectively.

[0054] Initially, the support plate 421 is located below the support rod 412, and the freshly cut hot angle steel is placed on the top wall of the support rod 412. During operation, the second drive component 422 drives all the support plates 421 to move upward first, lifting the angle steel from the support rod 412; then, the support plates 421 move the angle steel horizontally a short distance; next, the support plates 421 move the angle steel downward, placing it back on the support rod 412; finally, the support plates 421 return to their initial horizontal position. Through this cyclical action of lifting, translating, lowering, and retracting, the angle steel is conveyed laterally step by step on the cooling bed, making full contact with air during the movement, achieving the dual purpose of intermittent conveying and efficient cooling.

[0055] Reference Figure 1 To handle mass production, two sets of cooling mechanisms 4 are arranged side-by-side. To accurately distribute the angle steel to these two sets of cooling mechanisms 4, a guiding mechanism 6 is also provided between the shearing mechanism 3 and the cooling mechanism 4. The guiding mechanism 6 includes a main track 61 and two branch tracks 62. A rotatable deflector block 63 is located at the intersection of the main track 61 and the branch tracks 62. Below the deflector block 63 is a drive motor (not shown in the figure) for rotating the deflector block 63. The high-speed angle steel exiting the shearing mechanism 3 first moves along the main track 61. The control system can drive the deflector block 63 to rotate according to the current operating state of the two sets of cooling mechanisms 4, aligning the main track 61 with one of the branch tracks 62, thereby guiding the angle steel to the designated cooling mechanism 4. This automated diversion design avoids congestion in a single cooling channel, making the material flow of the entire production line smoother and increasing production capacity.

[0056] Reference Figure 8 and Figure 9Furthermore, the frame 411 is also equipped with a flipping mechanism 5 for driving the angle steel to flip. Multiple sets of flipping mechanisms 5 are provided, each corresponding to a support rod 412. Each flipping mechanism 5 includes a bearing block 51 and a first driving component 52. Multiple bearing blocks 51 are provided and evenly spaced along the length of the support rod 412. Each bearing block 51 includes two symmetrically arranged blocks, which are fixedly connected together to form a V-shaped block, with an obtuse angle between the open sides of the two blocks. The bearing block 51 is rotatably connected to the support rod 412, and its rotation axis is set along the length of the frame 411. The inner side of the bearing block 51 is used to support the angle steel. The first driving component 52 is located on one side of the support rod 412 and is used to drive multiple bearing blocks 51 on the same support rod 412 to rotate synchronously.

[0057] Reference Figure 9 and Figure 10 The first driving component 52 includes a sprocket 521, a chain 522, and a second motor 523. One end of the bearing block 51 is provided with a rotating rod 511, and the sprocket 521 is coaxially fixedly connected to the rotating rod 511. The chain 522 is wound between the sprockets 521, and the sprocket 521 at one end of the chain 522 is connected to the output shaft of the second motor 523. Therefore, after the second motor 523 is started, it can drive the corresponding sprocket 521 to rotate, so that the chain 522 runs. Multiple sprockets 521 rotate synchronously, so that multiple rotating rods 511 rotate synchronously, thereby driving multiple bearing blocks 51 to rotate synchronously, and flipping multiple angle steels placed on the frame 411 together.

[0058] When the angle steel needs to be flipped, the first driving component 52 drives the bearing blocks 51 to rotate around their axis by an angle. Since the angle steel is placed on these bearing blocks 51, the rotation of the bearing blocks 51 smoothly flips the angle steel. By flipping, it is possible to avoid a certain part of the angle steel continuously contacting the support rod 412, so that all parts of the angle steel can be exposed to the air, thereby achieving more uniform and thorough cooling. This helps to reduce the internal stress of the angle steel, improve the straightness of the finished product, and also reduce the amount of subsequent straightening. Since the included angle between the two blocks is an obtuse angle, the two blocks will not contact both sides of the angle steel at the same time. Therefore, after the angle steel is flipped, the parts of the angle steel that were originally supported can be exposed to the air, thereby achieving better cooling.

[0059] Reference Figure 9 Furthermore, each block is equipped with a support member 8, which includes a support column 81 and an elastic member 82. A through hole is formed in the block, and the support column 81 slides through the through hole; the elastic member 82 is a spring, fixedly connected between the side of the block near the support rod 412 and the bottom end of the support column 81. Under normal conditions, the elastic member 82 is at its original length, thus the top end of the support column 81 protrudes from the block. Figure 9 As shown, the angle steel is placed on the top wall of the left block, so the support column 81 on the left block is pushed to the bottom of this block, and the corresponding elastic element 82 is in a stretched state; the right block is in an inclined state, the top of the support column 81 on this block is spaced apart from the right side of the angle steel, and the elastic element 82 on this support column 81 is at its original length.

[0060] When the bearing block 51 rotates to the right, the block on the left will push the angle steel to rotate to the right as well. After the angle steel rotates to a small angle, the right side of the angle steel will abut against the top of the support column 81. As the rotation continues, the support column 81 on the right will be pushed downward. When the block on the right rotates to a horizontal position, due to the inertia of the angle steel itself, the angle steel will not stop immediately and will continue to rotate, thus continuing to push the support column 81 on the right downward until the right side of the angle steel rotates to a horizontal position. At this time, the angle steel has rotated 90° as a whole. Before flipping, the bearing block 51 supports the left outer wall of the angle steel. After flipping, the bearing block 51 supports the right outer wall of the angle steel, thereby preventing one side of the angle steel from continuously contacting the metal frame 411, which would cause this part to cool at a different rate than other parts, resulting in a large bending of the angle steel during the cooling process.

[0061] The support rod 412 has a clearance groove for the bottom end of the support column 81 to pass through, thus ensuring the smooth rotation of the bearing block 51.

[0062] Reference Figure 1 A feeding mechanism 7 is provided on one side of the cooling mechanism 4. The feeding mechanism 7 includes multiple conveying rollers 71, which are arranged along the length of the support rod 412 and are rotatable. Multiple conveying rollers 71 are provided and evenly spaced along the length of the frame 411. A drive sprocket is provided at the end of the conveying roller 71, and a drive chain is provided between two adjacent drive sprockets 521. The drive sprocket is driven by a motor, thereby driving the conveying roller 71. The top wall of the conveying roller 71 is used to support the angle steel. Therefore, after the transfer assembly 42 transfers the angle steel placed on the bearing block 51 on the frame 411 to the top wall of the conveying roller 71, the rotation of the conveying roller 71 can drive the angle steel to move along its own length.

[0063] Among them, conveying rollers are provided between heating mechanism 1 and forming mechanism 2, between forming mechanism 2 and shearing mechanism 3, and between shearing mechanism 3 and cooling mechanism 4. The conveying rollers are driven by motor, transmission sprocket and transmission chain, so as to realize the conveying of angle steel between each process.

[0064] The implementation principle of an automated angle steel processing production line according to an embodiment of this application is as follows: Rectangular billets are first heated to a suitable rolling temperature by a heating mechanism 1, and then fed into a forming mechanism 2 consisting of alternating vertical and horizontal rolling mills 21 and 22. After multiple passes of precise rolling, they are formed into L-shaped angle steel. Next, the continuously conveyed angle steel is cut to length by a shearing mechanism 3. The cut angle steel segments are automatically distributed to one of two parallel cooling mechanisms 4 via a guiding mechanism 6. In the cooling mechanism 4, the angle steel is conveyed laterally in a step-by-step manner by a transfer assembly 42, and during the conveying process, it is flipped by a flipping mechanism 5 integrated on a support rod 412 to achieve uniform and rapid cooling. Finally, the cooled angle steel is conveyed to the end of the production line, awaiting collection and packaging. The entire process is closely coordinated, achieving a high degree of automation.

[0065] The above are optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
