Description

Technical Field

[0001] The invention relates to the field of steel product processing, in particular to a shearing machine for steel product processing which is convenient for blanking. Background Art

[0002] After the steel strip coil is slitting and processed into steel bars, there is a high probability that there will be burrs on the edges of the steel bars, so the burrs on the steel bars need to be processed. The existing technology generally requires first rolling the slit steel bars into smaller steel bar coils, removing them from the slitting device and then transferring them to a removal device for processing the burrs. During the whole process, the steel bars need to be transferred, released and rewound many times, which is rather troublesome. In addition, the removal device generally performs bilateral processing on a single steel bar, which is less efficient. Summary of the invention

[0003] In order to overcome the disadvantage that the removal device can only perform bilateral processing on a single steel bar and has low efficiency, the present invention provides a shearing machine for processing steel products that is convenient for blanking.

[0004] The technical solution of the present invention is: a shearing machine for processing steel products that is convenient for blanking, including a slitting machine, a supporting frame and a limiting frame I; a slitting machine, a limiting frame I and a plurality of supporting frames are arranged in sequence along the material conveying direction; a buffer pool is arranged between the supporting frame and the limiting frame I; it also includes a limiting frame II, a rotating wheel frame I, a mounting frame, a connecting rod and a chamfering knife; a limiting frame II and a rotating wheel frame I are arranged in sequence along the material conveying direction; each supporting frame is rotatably connected to a rotating roller; the limiting frame I, the limiting frame II and the rotating wheel frame I are each provided with two rotating rollers distributed up and down, and the rotating rollers on the limiting frame I, the limiting frame II and the rotating wheel frame I are all connected to a power mechanism; two mounting frames are fixed to the rotating wheel frame I; each mounting frame is connected to a plurality of connecting rods, and all connecting rods installed on the same mounting frame are arranged in a "one" shape; each connecting rod is installed with a chamfering knife, and the chamfering knife is provided with two chamfering grooves and two pressing grooves, and the pressing groove is trumpet-shaped and the wider opening is the entrance, and the narrower opening is the exit.

[0005] More preferably, the mounting bracket is slidably connected to the connecting rod.

[0006] More preferably, empty grooves are provided between all the chamfered grooves and the corresponding pressed grooves.

[0007] More preferably, the surfaces of all rotating rollers on the limiting frame I, limiting frame II and rotating wheel frame I are provided with a rubber layer.

[0008] More preferably, it also includes a supporting round rod; two supporting round rods distributed up and down are fixedly connected to the side of the limiting frame II facing the rotating wheel frame I, and the two supporting round rods both support the upper and lower separated steel bars from below.

[0009] More preferably, a collecting frame is further included; the collecting frame is fixedly connected to the upper supporting round rod.

[0010] More preferably, a storage place is provided on the collection frame, and the storage place is in a circular ring shape as a whole.

[0011] More preferably, the inner surface of the storage place is smooth.

[0012] More preferably, it also includes a blowing plate; the blowing plate is fixedly connected to the collecting frame; the blowing plate has a plurality of air ports, all of which face the empty slots, the air ports above the blowing plate are used for suction, and the air ports below the blowing plate are used for blowing.

[0013] More preferably, a filter is provided at the air outlet above the blowing plate.

[0014] Beneficial effects: The present invention separates the steel bars alternately up and down in sequence to form an alternating distribution pattern, which is then reassembled to expose both sides of a single steel bar in a dispersed state. When the steel bars are still in a separated state, the steel bars are allowed to pass through the chamfering grooves of each chamfering knife in a separated posture. The chamfering knife trims the edge of the steel bar to make the sharp edge smooth, thereby processing the edges of multiple steel bars at the same time.

[0015] The present invention uses the entrance end of the pressing groove to press down the burrs on the edge of the steel bar before trimming the edge of the steel bar in the chamfering groove, so that the burrs on the edge of the steel bar are concentrated and face the opposite direction of their own moving direction, and then are removed by the chamfering groove. This will reduce the resistance of the chamfering groove to the burrs, which is beneficial to the edge trimming process. The removed part has stronger continuity, is more likely to form filamentous waste, and is not easy to form fragmented waste that splashes to other positions, thereby improving the chamfering knife's passivation treatment effect on the edge of the steel bar.

[0016] The present invention adds a supporting round rod at a short distance before the chamfering knife. The supporting round rod supports the suspended steel bar at a position close to the resistance application point, thereby reducing the influence of the resistance on the steel bar and further improving the stability of conveying the steel bar.

[0017] The present invention conveys air through the air port below the blow plate and provides suction force for the air port above the blow plate. The air is blown from the air port below the blow plate to and passes through the empty slots at different positions, guiding the generated filamentary waste to leave the empty slots and avoid contact with the chamfering knife as much as possible to prevent obstruction and stacking problems. After the suction force appears in the air port above the blow plate, the suction force of the air port above the blow plate guides and pulls the filamentary waste, allowing the filamentary waste to transfer to the air port above the blow plate, which is beneficial to the collection of the filamentary waste.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0021] Example 1 A shearing machine for processing steel products that is easy to cut, such as Figure 1-Figure 5 As shown, it includes a slitting machine 3, a carrier frame 4 and a limiting frame Ⅰ5; the slitting machine 3, the limiting frame Ⅰ5 and a plurality of carrier frames 4 are sequentially arranged along the material conveying direction; a buffer pool 11 is arranged between the carrier frame 4 and the limiting frame Ⅰ5; It also includes a limiting frame Ⅱ6, a rotating wheel frame Ⅰ7, a mounting frame 110, a connecting rod 111 and a chamfering knife 112; the limiting frame Ⅱ6 and the rotating wheel frame Ⅰ7 are arranged in sequence along the material conveying direction; each supporting frame 4 is rotatably connected to a rotating roller; the limiting frame Ⅰ5, the limiting frame Ⅱ6 and the rotating wheel frame Ⅰ7 are each provided with two rotating rollers distributed up and down, and the rotating rollers on the limiting frame Ⅰ5, the limiting frame Ⅱ6 and the rotating wheel frame Ⅰ7 are all connected to a power mechanism; two mounting frames 110 are fixedly connected to the rotating wheel frame Ⅰ7; each mounting frame 110 is connected to a number of connecting rods 111, and all the connecting rods 111 installed on the same mounting frame 110 are arranged in a "one" shape; each connecting rod 111 is installed with a chamfering knife 112, and the chamfering knife 112 is provided with two symmetrical chamfering grooves 1121 and two symmetrical crushing grooves 1123, and the crushing groove 1123 is trumpet-shaped and the wider opening is the entrance, and the narrower opening is the exit.

[0022] The surfaces of all rotating rollers on the limiting frame Ⅰ5, limiting frame Ⅱ6 and rotating wheel frame Ⅰ7 are provided with rubber layers, so that the steel bars pressed on the limiting frame Ⅰ5, limiting frame Ⅱ6 and rotating wheel frame Ⅰ7 can move more stably.

[0023] The mounting frame 110 is slidably connected to the connecting rod 111. During installation, you only need to slide the connecting rod 111 into the mounting frame 110. During processing, the force applied by the steel bar to the chamfering knife 112 will not cause the connecting rod 111 to have a tendency to separate from the mounting frame 110, so it will not affect the stability of the connecting rod 111, and it is convenient for installation and disassembly.

[0024] Empty grooves 1122 are provided between all the chamfering grooves 1121 and the corresponding crushing grooves 1123 to facilitate the discharge of the filamentous waste.

[0025] Before processing, the steel coil 1 is placed on the material conveying device 2, and then the free end of the steel coil 1 is placed in the slitting machine 3, and the slitting machine 3 is started to slit the steel coil 1, and the steel coil 1 is cut into steel bars. The material conveying device 2 is controlled to continuously release the steel coil 1, and at the same time, the operator uses a tool to pull the slit steel bar through the limiting frame Ⅰ5, and through the operator's regulation and the support of the carrier frame 4, the part of the slit steel bar located between the limiting frame Ⅰ5 and the slitting machine 3 is not in a taut state, and falls into the buffer pool 11. The buffer pool 11 stores a certain amount of steel strips, thereby playing a regulating role between different links of the production line. When the production speed of the slitting machine 3 is faster than the winding speed of the steel bar, the excess steel strips can be temporarily stored in the buffer pool 11 to avoid production interruption or equipment damage caused by speed mismatch. Under normal circumstances, the steel bar passing through the limiting frame Ⅰ5 symbolizes the completion of the slitting process.

[0026] Considering that after the steel coil 1 is slit into steel bars, there is a high probability that there will be burrs on the steel bars, and the burrs on the steel bars need to be processed. The prior art generally requires the steel bars to be removed from the slitting device and transferred to the removal device for burr processing, which is more troublesome, and the removal device generally processes a single steel bar, which is less efficient. By adding a limiting frame Ⅱ6 and a rotating wheel frame Ⅰ7, the limiting frame Ⅱ6 and the rotating wheel frame Ⅰ7 are arranged successively after the limiting frame Ⅰ5, and the limiting frame Ⅰ5, the limiting frame Ⅱ6 and the rotating wheel frame Ⅰ7 are all provided with two rotating rollers distributed up and down. When the steel bar passes through the limiting frame Ⅰ5, it passes between the two rotating rollers, and then when passing through the limiting frame Ⅱ6, the steel bar needs to be separated up and down alternately in turn, and the steel bar separated upward is pressed on the top of the rotating roller above the limiting frame Ⅱ6, and the steel bar separated downward is pressed on the bottom of the rotating roller below the limiting frame Ⅱ6. The alternating distribution pattern formed is as follows Figure 3As shown, the steel bars are gathered again after passing through the limiting frame Ⅱ6, and are all sent to the rotating wheel frame Ⅰ7, passing between the two rotating rollers of the rotating wheel frame Ⅰ7. In this process, because of the alternating separation effect played by the limiting frame Ⅱ6, both sides of a single steel bar are exposed, and the edges of multiple steel bars can be processed at the same time.

[0027] Before the steel bars leave the limiting frame II6 and pass through the rotating wheel frame I7, they are still in a separated state. The steel bars are allowed to pass through the chamfering grooves 1121 of the chamfering cutters 112 in a separated posture. The chamfering cutters 112 trim the edges of the steel bars to make the sharp edges smooth. Moreover, a pressing groove 1123 is set before the rounded edges are scraped. The steel bars need to pass through the pressing groove 1123 before entering the chamfering groove 1121, and the pressing groove 1123 is adjusted to a state of gradually shrinking from the inlet end to the outlet end. The size of the inlet end of the pressing groove 1123 is only 0.3 mm larger than the untreated edge of the steel bar. Around, in most cases, the shortest burr is this length. The purpose is to use the entrance end of the pressing groove 1123 to press down the burrs on the edge of the steel bar before the chamfering groove 1121 trims the edge of the steel bar, so that the burrs on the edge of the steel bar are concentrated and face the opposite direction of their own moving direction, and then are removed by the chamfering groove 1121. This will reduce the resistance of the chamfering groove 1121 to the burrs, which is beneficial to the edge trimming process, and the removed part has stronger continuity, is more likely to form filamentous waste, and is not easy to form fragmented waste and splash to other locations, thereby improving the chamfering knife 112 on the passivation treatment effect of the steel bar edge.

[0028] If the filamentary waste is not discharged in time, it will easily interfere with the operation of the crushing groove 1123. Therefore, an empty groove 1122 is opened between the chamfering groove 1121 and the crushing groove 1123. Moreover, because the slitting and edge processing are carried out in the same process, the overall movement speed of the steel bar will not be very fast, so that the generated filamentary waste can directly fall down from the empty groove 1122 and be discharged, thereby avoiding it from entering the crushing groove 1123 and interfering with the normal functioning of the crushing groove 1123.

[0029] Example 2 On the basis of Example 1, Figure 2-Figure 4 As shown, it also includes a supporting round rod 201; the limiting frame II6 is detachably connected to one side of the rotating wheel frame I7 with two supporting round rods 201 distributed up and down, and the two supporting round rods 201 both support the upper and lower separated steel bars from below.

[0030] It also includes a collecting frame 202; the collecting frame 202 is fixedly connected to the supporting round rod 201 located above.

[0031] A storage place 2021 is provided on the collection frame 202. The storage place 2021 is in a circular ring shape as a whole, which is convenient for collecting and cleaning the filamentous waste.

[0032] The inner surface of the storage 2021 is smooth, which is conducive to the cleaning of filamentary waste.

[0033] It also includes a blowing plate 203; the blowing plate 203 is fixedly connected to the collecting frame 202; the blowing plate 203 has two air ports, both of which face the empty slot 1122, the upper air port of the blowing plate 203 is used for suction, and the lower air port of the blowing plate 203 is used for blowing.

[0034] A filter screen is provided at the air port above the blowing plate 203 to prevent filamentous waste from entering the air port of the blowing plate 203 .

[0035] Taking into account that during the process of removing the burrs of the steel bar, the chamfering knife 112 and the steel bar are subjected to resistance exerted by each other, the chamfering knife 112 is fixed to the mounting frame 110 by the connecting rod 111 and will not be affected, while the area where the steel bar is processed is in a suspended state and is insufficiently supported. When resistance is applied to the steel bar, the steel bar is affected by the resistance and there is a probability that the steel bar will become unstable, affecting the edge processing of the steel bar. By adding a supporting round rod 201 at a short distance before the chamfering knife 112, the supporting round rod 201 supports the suspended steel bar at a position close to the resistance application point, thereby reducing the influence of the resistance on the steel bar and further improving the stability of conveying the steel bar. In addition, for the steel bar separated upward, a collecting frame 202 is added to the supporting round rod 201. Through the collecting frame 202 The removed filamentary waste is blocked to prevent the filamentary waste from falling downward and contacting the steel bars separated downward to cause entanglement interference problems, and the filamentary waste is guided by the collecting frame 202 and gathered in the storage place 2021. The storage place 2021 is in a circular shape as a whole. When the filamentary waste enters the storage place 2021, the filamentary waste is guided by the storage place 2021 to gather together. When cleaning, only a long rod with a disc that matches the shape of the storage place 2021 is needed to be pushed into the storage place 2021 from one end, so that the filamentary waste can be completely pushed out from the other end of the storage place 2021. The filamentary waste is not dispersed, which is conducive to subsequent cleaning and collection; the filamentary waste produced by the steel bars separated downward can be directly dropped on the ground or into a collection container placed on the ground.

[0036] When the filamentary waste is guided to be discharged from the empty slot 1122, the filamentary waste will be in a hanging shape due to the influence of gravity. Especially for the filamentary waste from the upward separated steel bars, if it hangs down and touches the chamfering knife 112 after being discharged from the empty slot 1122, it is easy to be blocked, resulting in poor discharge and stacking. Therefore, by adding a blowing plate 203 to the collection frame 202, before removing the burrs of the steel bars, the blowing plate 203 is connected to the external air source and the external vacuum pump respectively, and then the external air source and the external vacuum pump are started to deliver air to the air port below the blowing plate 203 and provide suction force for the air port above the blowing plate 203, and the air is blown from the air port below the blowing plate 203 to and through The empty slots 1122 at different positions guide the generated filamentary waste to leave the empty slots 1122 and avoid contact with the chamfering knife 112 as much as possible to prevent obstruction and stacking problems. After the suction force appears at the air port above the blowing plate 203, the wind suction force is controlled not to be very strong, and the filamentary waste will not be sucked at the air port above the blowing plate 203 and unable to move. The filamentary waste is only guided and pulled by the suction force of the air port above the blowing plate 203, so that the filamentary waste can more easily pass through the empty slots 1122 and move downward when discharged instead of running to other places, thereby guiding the filamentary waste to move in the direction of the collection frame 202, which is conducive to the collection of the filamentary waste.

[0037] By adding a filter screen at the air port above the blowing plate 203 , when the filamentary waste is transferred to the air port above the blowing plate 203 , the filamentary waste is prevented from entering the air port of the blowing plate 203 .

Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
