Description

Technical Field

[0001] The present application belongs to the technical field of casting auxiliary tool manufacturing, and more specifically, to an automatic local heating bending mechanism for steel bars. Background Art

[0002] Casting companies need to perform shot blasting on castings after casting and sand cleaning. On the one hand, it further cleans the surface of the castings, and on the other hand, it is beneficial to improve the surface hardness of the castings. When shot blasting such castings, fishing hooks or hanging baskets made of steel bars are required. Since fishing hooks or hanging baskets need to be replaced when they are worn to a certain extent by the impact of steel shots, they are consumable parts. When repairing or making new fishing hooks or hanging baskets, the steel bars need to be partially bent and formed. In the traditional local heating and bending method of steel bars, manual operation is usually relied on, and flames are used to heat specific areas of the steel bars, and then external forces are used to bend them to the desired angle and shape. However, this method has many limitations, such as uneven heating, low operating efficiency, harsh working environment, and difficulty in ensuring bending accuracy. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a steel bar automatic local heating and bending mechanism to solve the technical problem of poor steel bar heating and bending effect in the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is: to provide a steel bar automatic local heating bending mechanism, comprising:

[0005] A feeding mechanism, forming a feeding hole capable of reciprocatingly feeding the steel rod;

[0006] Induction heaters, which have induction coils for heating the steel rod;

[0007] The bending mechanism comprises a main shaft and a rotating wheel rotatably mounted on the main shaft, wherein the rotating wheel is provided with spaced support columns in a radial direction, wherein the space between the support columns is located between the feeding hole and the induction coil and can face the feeding hole and the induction coil during the rotation of the rotating wheel;

[0008] A driving motor is transmission-connected to the rotating wheel and is used to drive the rotating wheel.

[0009] Optionally, the rotating wheel comprises an inner disc and an outer ring which is spaced apart from the inner disc and is used for transmission connection to the driving motor, and the inner disc and the outer ring are connected by spokes;

[0010] The supporting column is arranged on the inner plate.

[0011] Optionally, one of the support columns is coaxially connected to the main shaft.

[0012] Optionally, the height of the support column connected to the main shaft in the axial direction of the rotating wheel is lower than the height of another support column.

[0013] Optionally, the support column connected to the main shaft is hollow and coaxially sleeved on the main shaft.

[0014] Optionally, the support column connected to the main shaft forms a flange on a side close to the rotating wheel and abuts against the rotating wheel through the flange.

[0015] Optionally, the drive motor further includes a drive gear connected to the power end, and the outer ring and the drive gear form a gear transmission pair.

[0016] Optionally, the spokes are U-shaped channel steels.

[0017] Optionally, six spokes are evenly arranged around the central axis of the rotating wheel.

[0018] Optionally, the feeding mechanism, the induction heater and the driving motor are communicatively connected.

[0019] The beneficial effect of the automatic local heating and bending mechanism for steel bars provided in the present application is that: compared with the prior art, in the automatic local heating and bending mechanism for steel bars provided in the present application, since the feeding mechanism can reciprocate the steel bars through the feeding hole and the feeding hole is directly opposite to the gap between the support columns and the induction coil in the induction heater, the steel bars can be driven by the feeding hole and sequentially pass through the gap between the support columns and extend into the induction coil for heating; after the steel bars are heated, the steel bars can be pulled back through the feeding hole and the heated part of the steel bars can be delivered to the gap between the support columns, so that when the rotating wheel rotates, the steel bars can be conveniently bent and formed. Since the delivery of the steel bars in the present application is automatically controlled by the feeding mechanism, the consumption of manpower and material resources is greatly reduced and a better bending and forming effect can be formed, which is far superior to the prior art. In addition, the steel bars in the present application are heated by the induction coil, which greatly avoids the harsh working environment caused by the traditional heating method, significantly reduces the labor intensity of the enterprise's mechanics, and can also better protect the health of the operators.

[0027] See also Figure 1 Now, an automatic local heating bending mechanism for steel bars provided in an embodiment of the present application is described. The automatic local heating bending mechanism for steel bars comprises a feeding mechanism 100, an induction heater 200, a bending mechanism 300 and a driving motor 400. Among them:

[0028] The feeding mechanism 100 forms a feeding hole 101 capable of reciprocatingly feeding a steel bar, the induction heater 200 has an induction coil 201 for heating the steel bar, the bending mechanism 300 comprises a main shaft 301 and a rotating wheel 302 rotatably mounted on the main shaft 301, the rotating wheel 302 is radially provided with spaced support columns 303, the space between the support columns 303 is located between the feeding hole 101 and the induction coil 201 and can be directly opposite to the feeding hole 101 and the induction coil 201 during the rotation of the rotating wheel 302, the driving motor 400 is transmission-connected to the rotating wheel 302 and is used to drive the rotating wheel 302, here, it can be It is understood that the feeding mechanism 100 can be a mechanism driven by a linear drive source in the prior art for reciprocating direct motion, such as a sliding seat having a linear guide (not shown) for sliding guidance and driven by a cylinder, the longitudinal direction of the linear guide faces the induction coil 201, a feeding hole 101 is formed on the sliding seat and the feeding hole 101 faces the induction coil 201, a clamping block (not shown) controlled by a cylinder is radially arranged in the feeding hole 101, when the steel rod is fed into the feeding hole 100 by the feeding device and the front end of the steel rod extends a set distance, the clamping block clamps the steel rod, and then the sliding seat advances a set distance, so that the front end of the steel rod enters the induction coil for heating.

[0029] According to the above structure provided in the present embodiment, in the automatic local heating and bending mechanism for steel bars provided in the present embodiment, since the feeding mechanism 100 can reciprocate the steel bars through the feeding hole 101 and the feeding hole 101 is directly opposite to the gap between the support columns 303 and the induction coil 201 in the induction heater 200, the steel bars can be driven by the feeding hole 101 and sequentially pass through the gap between the support columns 303 and extend into the induction coil 201 for heating; after the steel bars are heated, they can be pulled back through the feeding hole 101 and the heated part of the steel bars can be fed to the gap between the support columns 303. Since the feeding hole 101 feeds the unheated steel bars to the steel bars, the steel bars can be heated to the gap between the support columns 303. The degree of freedom of the heated end in the radial direction is limited, so that when the rotating wheel 302 rotates, the steel bar can be easily bent into shape through the action of the support column 303. After completion, the feeding mechanism 100 continues to retreat a set distance to make the end of the steel bar leave the surface of the feeding port 101, that is, the partially bent steel bar can be taken out from above the rotating wheel 302 by the material taking mechanism or manually, and then the local bending operation of the next steel bar can be performed according to the above process; since the transportation of the steel bar in this embodiment is automatically controlled by the feeding mechanism 100, it greatly reduces the consumption of manpower and material resources and can form a better bending and forming effect, which is far better than the existing technology. In addition, in this embodiment, the steel bar is heated by the induction coil 201, which greatly avoids the harsh working environment caused by the traditional heating method, and can also better protect the health of the operator.

[0030] In another embodiment of the present application, see Figure 1The rotating wheel 302 includes an inner disk 321 and an outer ring 322 which is arranged concentrically with the inner disk 321 and is used for transmission connection with the driving motor 400. The inner disk 321 and the outer ring 322 are connected by spokes 323, and the support column 303 is arranged on the inner disk 321. According to the above structure provided in this embodiment, on the one hand, the driving motor 400 is connected to the outer ring 322 of the rotating wheel 302 by transmission, which is conducive to increasing the rotation torque of the rotating wheel 302, so that the steel rod can be bent more conveniently and the technical effect of energy saving and emission reduction can be achieved; on the other hand, the rotating wheel 302 adopts the method of connecting the inner ring and the outer ring 322 by spokes 323, which can further reduce the dead weight, which is conducive to further reducing the power of the driving motor 400.

[0031] In another embodiment of the present application, see Figure 1 , one of the support columns 303 is coaxially connected to the main shaft 301. According to the above structure provided in this embodiment, one of the support columns 303 is connected to the main shaft 301 so that the interval between the support columns 303 is closer to the center of the rotating wheel 302, which is conducive to the support column 303 outside the center bending and extruding the steel rod when the rotating wheel 302 rotates. At this time, the support column 303 connected to the main shaft 301 plays the role of a fulcrum, so that the local bending angle of the steel rod can be conveniently controlled by controlling the rotation angle of the rotating wheel 302, making the bending and forming of the steel rod easier.

[0032] In another embodiment of the present application, see Figure 1 , the height of the support column 303 connected to the main shaft 301 in the axial direction of the rotating wheel 302 is lower than the height of the other support column 303. According to the above structure provided in this embodiment, since the support column 303 connected to the main shaft 301 is on the inner side of the steel bar bending, and the support column 303 not connected to the main shaft 301 is on the outer side of the steel bar bending, increasing the height of the support column 303 not connected to the main shaft 301 is conducive to better adapting to the bending of the steel bar and ensuring that the steel bar can be stably clamped between the support columns 303 during the bending process. In addition, the support columns 303 with different heights can also facilitate the removal of the steel bar after the bending, and have a good use effect.

[0033] In another embodiment of the present application, see Figure 1 The support column 303 connected to the main shaft 301 is hollow and coaxially mounted on the main shaft 301. According to the above structure provided in this embodiment, the support column 303 coaxially mounted on the main shaft 301 can not only form a more stable connection with the main shaft 301, but also further improve its own structural strength, so that the bending process of the steel bar can be carried out more stably.

[0034] In another embodiment of the present application, see Figure 1 The support column 303 connected to the main shaft 301 forms a flange 331 on the side close to the rotating wheel 302 and abuts against the rotating wheel 302 through the flange 331. According to the above structure provided in this embodiment, the support column 303 connected to the main shaft 301 abuts against the rotating wheel 302 through the flange 331 to achieve further stability, which is conducive to further facilitating the bending of the steel bar.

[0035] In another embodiment of the present application, see Figure 1 The driving motor 400 further includes a driving gear 401 connected to the power end, and the outer ring 322 and the driving gear 401 form a gear transmission pair. According to the above structure provided in this embodiment, the driving motor 400 can more stably drive the rotating wheel 302 to rotate around the main shaft 301 through the gear transmission pair composed of the driving gear 401 and the outer ring 322, which is conducive to further facilitating the bending of the steel bar. Here, the preferred driving motor 400 uses a servo motor to control the bending angle of the steel bar.

[0036] In another embodiment of the present application, see Figure 1 , the spokes 323 are U-shaped channel steels. According to the above structure provided in this embodiment, the spokes 323 made of U-shaped channel steels can significantly improve the structural strength of the rotating wheel 302, which is conducive to making the bending process of the steel bar more stable.

[0037] In another embodiment of the present application, see Figure 1 , six spokes 323 are evenly arranged around the central axis of the rotating wheel 302. According to the above structure provided in this embodiment, evenly arranging six spokes 323 can further increase the structural strength of the rotating wheel 302.

[0038] In another embodiment of the present application, see Figure 1 The feeding mechanism 100, the induction heater 200 and the driving motor 400 are in communication connection. According to the above structure provided in this embodiment, the feeding mechanism 100, the induction heater 200 and the driving motor 400 in communication connection are conducive to making the steel bar automatic local heating bending mechanism provided in this embodiment run more automatically.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
