Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and specifically relates to a steel bar straightening machine. Background Art

[0002] The length of steel bars when they leave the factory is generally one hundred to several hundred meters long. For easy transportation, they are wound into discs (coils) for transportation. Before use, they are straightened by a steel bar straightening machine and cut into appropriate lengths for use. For example, patent CN202223135800.3 discloses a steel bar processing and straightening equipment with a rust removal structure. The steel bars are straightened by rolling friction between the straightening roller group and the steel bars. In order to simultaneously straighten and remove rust from the steel bars, a rust removal component is also provided at the transmission front end of the straightening roller group. The rust on the steel bars is brushed, separated, wiped, etc. in turn by the steel brush roller, extrusion roller and grinding roller of the rust removal component.

[0003] The above patent technical solution also has the following technical problems: the spacing of the straightening roller group and the inner diameter of the mounting ring of the rust removal component are fixed, and can only be applied to steel bars of the same specification. In addition, the straightening roller group will inevitably wear out after long-term use, and if the spacing cannot be adjusted, the straightening effect will be affected. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a steel bar straightening machine to solve the problem that the straightening roller group will inevitably wear out after long-term use, and the straightening effect will be affected under the premise that the spacing cannot be adjusted.

[0005] According to the embodiment of the utility model, the utility model adopts the following technical solution:

[0006] The steel bar straightening machine includes a frame, on which a conveying mechanism, a rust removal mechanism and a straightening mechanism are arranged in sequence, the straightening mechanism includes a straightening assembly for straightening the steel bars, the straightening assembly includes a supporting wheel rotatably connected to the frame, a mounting plate slidably connected to the frame and a pressure wheel rotatably connected to the mounting plate, and a channel for the steel bars to pass through is formed between the supporting wheel and the pressure wheel; the straightening mechanism also includes a detection assembly for detecting wear on the outer walls of the supporting wheel and the pressure wheel, the detection assembly includes a detection rod slidably connected to the frame, the detection rod is used to be inserted between the supporting wheel and the pressure wheel, and pressure sensors are installed on the upper and lower sides of the detection rod, and the pressure sensors are used to detect the pressure of the supporting wheel and the pressure wheel on the detection rod.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] In this solution, when straightening, the mounting plate can be slid according to the outer diameter of the steel bar, so that the mounting plate drives the pressing wheel to change its position, thereby adjusting the distance between the pressing wheel and the supporting wheel to be suitable for different steel bar specifications. Even if the outer walls of the pressing wheel and the supporting wheel are worn to a certain extent, the distance between the pressing wheel and the supporting wheel can be adjusted to make it suitable for steel bar straightening.

[0009] However, when the wear on the outer walls of the pressure wheel and the support wheel is uneven, for example, the wear on one side of the pressure wheel or the support wheel is greater, while the wear on other parts is smaller, it will also cause different squeezing effects on the steel bars when the pressure wheel and the support wheel rotate one circle, affecting the straightening. For this reason, a detection component is designed in this scheme. Before straightening, a detection rod is inserted between the support wheel and the pressure wheel, and the pressure wheel and the support wheel are rotated one circle. Then, a pressure sensor is used to detect whether the pressure generated on the detection rod is consistent during the process of the pressure wheel and the support wheel rotating one circle, and then it is determined whether the wear on the outer walls of the pressure wheel and the support wheel is uniform, so as to choose whether to maintain the pressure wheel and the support wheel based on the detection results to achieve better straightening effect.

[0010] Furthermore, multiple support wheels and pressure wheels are arranged in the transverse direction, and the support wheels and pressure wheels are distributed in an alternating manner.

[0011] Furthermore, the rust removal mechanism comprises a slide plate which is vertically slidably connected to the frame and a frosted ring which is rotatably connected to the slide plate, and a frosted layer is provided on the inner wall of the frosted ring.

[0012] Furthermore, a rust removal ring is rotatably connected to the slide plate, and a plurality of rollers are rotatably connected to the inner wall of the rust removal ring along the circumferential direction. The axes of the rollers are parallel to the axis of the rust removal ring, and steel brushes are arranged on the outer walls of the rollers.

[0013] Further, the rust removal rings and the grinding rings are distributed along the direction from the conveying mechanism to the straightening mechanism.

[0014] Furthermore, there are multiple frosted rings and rust removal rings and they are vertically distributed on the slide. The inner diameters of the multiple frosted rings are different, and the inner diameters of the multiple rust removal rings are different. The frosted rings and rust removal rings correspond to each other one by one and the inner diameters of the corresponding frosted rings and rust removal rings are consistent.

[0015] Furthermore, the detection component also includes a controller and an alarm. The pressure sensor and the alarm are both connected to the controller signal. The signal input end of the controller is used to receive the pressure signal of the pressure sensor, and the signal output end of the controller is used to control the opening and closing of the alarm.

[0016] Furthermore, the detection assembly includes a detection plate connected to the frame in a vertical sliding manner, and the detection rod is connected to the detection plate in a horizontal sliding manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the steel bar straightening machine includes a frame, on which a conveying mechanism, a rust removal mechanism and a straightening mechanism are arranged in sequence, the straightening mechanism includes a straightening assembly for straightening the steel bar 3, the straightening assembly includes a supporting wheel 4 rotatably connected to the frame, a mounting plate 2 slidably connected to the frame, and a pressing wheel 1 rotatably connected to the mounting plate 2, the mounting plate 2 is arranged above the supporting wheel 4 along a vertical sliding manner, a cylinder for driving the mounting plate 2 to slide is installed on the frame, and a plurality of supporting wheels 4 and pressing wheels 1 are arranged in the transverse direction, and the supporting wheels 4 and pressing wheels 1 are staggered, and a channel (i.e., a straightening channel) for the steel bar 3 to pass through is formed between the supporting wheels 4 and the pressing wheels 1, and the steel bar 3 passes through the straightening channel between the supporting wheels 4 and the pressing wheels 1, and is squeezed by the supporting wheels 4 and the pressing wheels 1 to complete the straightening.

[0024] The straightening mechanism also includes a detection component for detecting the wear of the outer wall of the support wheel 4 and the pressure wheel 1. The detection component includes a detection rod 10 slidably connected to the frame. Specifically, the detection component also includes a detection plate 9 slidably connected to the frame in a vertical direction. The detection rod 10 is slidably connected to the detection plate 9 in a horizontal direction. A cylinder for driving the detection plate 9 to slide is installed on the frame. A cylinder for driving the detection rod 10 to slide is also installed on the detection plate 9. The detection rod 10 is used to be inserted between the support wheel 4 and the pressure wheel 1. Pressure sensors 11 are installed on both the upper and lower sides of the detection rod 10. The pressure sensor 11 is used to detect the pressure of the support wheel 4 and the pressure wheel 1 on the detection rod 10.

[0025] In specific use, according to the outer diameter specification of the steel bar 3, the mounting plate 2 is slid so that the mounting plate 2 drives the pressing wheel 1 to change its position, and the spacing of the straightening channel formed between the pressing wheel 1 and the supporting wheel 4 is adjusted so that the steel bar 3 is subjected to a certain degree of squeezing force when passing through the straightening channel. The steel bar 3 is conveyed through the straightening channel by a conveying mechanism to complete the straightening. In actual use, the conveying mechanism can be a conventional mechanical arm or other structure in the prior art, as long as it can push the steel bar 3 into the straightening channel.

[0026] In order to prevent the support wheel 4 and the pressure wheel 1 from affecting the straightening due to wear, before straightening, the detection plate 9 is slid to align the detection rod 10 with the straightening channel, and the detection rod 10 is slid to insert the detection rod 10 into the straightening channel, and then the pressure wheel 1 and the support wheel 4 are rotated one circle. Then, the pressure sensor 11 is used to detect whether the pressure generated on the detection rod 10 during the rotation of the pressure wheel 1 and the support wheel 4 is consistent. For example, when the detection rod 10 is inserted into the straightening channel, the pressure sensor 11 on the upper side of the detection rod 10 detects that the pressure generated by the pressure wheel 1 on the detection rod 10 is F1. When the pressure wheel 1 rotates one circle, the pressure generated on the detection rod 10 at a certain point of the pressure wheel 1 changes from F1 to F2, which means that the wear on the outer wall of the pressure wheel 1 is not uniform, and the operator needs to perform maintenance.

[0027] In another embodiment of the present invention, Figure 1 , Figure 4 As shown, the rust removal mechanism includes a slide plate 5 connected to the frame in a vertical sliding manner and a frosting ring 6 connected to the slide plate 5 in a rotatable manner. A cylinder for driving the slide plate 5 to slide is installed on the frame, and a motor for driving the frosting ring 6 to rotate is installed on the slide plate 5. The inner wall of the frosting ring 6 is provided with a frosting layer, which can be formed by frosting the inner wall of the frosting ring 6, or can be sandpaper bonded to the inner wall of the frosting ring, which is used to grind the outer wall of the steel bar 3. A rust removal ring 7 is also rotatably connected to the slide plate 5, and a motor for driving the rust removal ring 7 to rotate is installed on the slide plate 5. The inner wall of the rust removal ring 7 is connected to a plurality of rollers 8 in a circumferential rotation, and the axis of the rollers 8 is parallel to the axis of the rust removal ring 7. The outer wall of the rollers 8 is provided with a steel brush. When the steel bar 3 passes through the rust removal ring 7, the rollers 8 drive the steel brush to move relative to the steel bar 3 through the rotation of the rust removal ring 7, and the rust on the outer wall of the steel bar 3 is brushed off.

[0028] The rust removal ring 7 and the grinding ring 6 are distributed along the direction from the conveying mechanism to the straightening mechanism, that is, the steel bar 3 first passes through the rust removal ring 7 and then passes through the grinding ring 6. During specific use, the conveying mechanism conveys the steel bar 3 through the rust removal ring 7, the grinding ring 6 and the straightening mechanism in sequence. The rust removal ring 7 and the grinding ring 6 rotate relative to the steel bar 3 to remove and grind the rust on the outer wall of the steel bar 3, and then the steel bar 3 passes through the straightening mechanism for straightening.

[0029] In order to make the frosted ring 6 and the rust removal ring 7 suitable for different outer diameter specifications of the steel bars 3, the frosted ring 6 and the rust removal ring 7 are provided in plurality and are vertically distributed on the slide plate 5, the inner diameters of the plurality of frosted rings 6 are different, the inner diameters of the plurality of rust removal rings 7 are different, the frosted rings 6 and the rust removal rings 7 correspond to each other one by one and the inner diameters of the corresponding frosted rings 6 and the rust removal rings 7 are consistent, so as to Figure 4 As shown in the figure, there are three groups of frosted rings 6 and rust removal rings 7. According to the steel bars 3 of different specifications, the sliding slide 5 can be used to align the axes of the frosted rings 6 and rust removal rings 7 with suitable inner diameters with the straightening channels between the support wheel 4 and the pressure wheel 1.

[0030] In another embodiment of the utility model, the detection component also includes a controller and an alarm. The pressure sensor 11 and the alarm are both connected to the controller signal. The signal input end of the controller is used to receive the pressure signal of the pressure sensor 11, and the signal output end of the controller is used to control the opening and closing of the alarm. The controller can select a single-chip microcomputer or other microcontroller, and the alarm can select an indicator light or a buzzer to remind the operator by emitting light or sound. In this embodiment, when the wear of the pressure wheel 1 and the support wheel 4 is detected by the detection rod 10, when the pressure signal detected by the pressure sensor 11 changes, the alarm can be controlled by the controller to issue a warning to remind the operator.
