Technical Field
[0001] The utility model relates to the technical field of reinforced concrete product industry, in particular to a device for detecting the curvature of a slender component. Background Art
[0002] In the reinforced concrete products industry, fixed-length cutting machines are commonly used. Fixed-length cutting machines are important machines used to form the steel skeleton of cement products (such as drainage pipes, prefabricated piles for high-rise buildings, and some chemical products). They are used to cut rolled steel bars into several fixed-length steel bars. For example, when producing prefabricated piles, the main reinforcement cage must be manufactured first. The main reinforcement cage consists of several main bars distributed in a ring shape and spiral bars roll-welded on the periphery of several main bars. The main reinforcement is a PC steel bar obtained by cutting it with a fixed-length cutting machine. Therefore, the fixed-length cutting machine is the main reinforcement cutting equipment for main reinforcement cage formation, and is widely used in cement products and construction fields.
[0003] In the prior art, a small number of the cut-to-length steel bars obtained by the cut-to-length machine are bent. However, the existing cut-to-length machine does not have the function of screening or detecting the bending of the steel bars, resulting in the flow of the cut-to-length steel bars with excessive bending into the subsequent production process, which is likely to cause the subsequent processing equipment to fail or the quality of the formed cage reinforcement to be poor. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a slender component bending detection device, which can effectively detect whether the cut fixed-length steel bars are bent beyond the standard.

[0011] A preferred embodiment of the above technical solution is that the slender component curvature detection device also includes several sensor fixing brackets that are fixedly arranged and correspond one-to-one to the several detection sensors, the sensor fixing bracket includes a bottom horizontal plate portion, a vertical plate portion that is bent upward and extended from one end of the bottom horizontal bracket, and a top horizontal plate portion that is horizontally bent and extended from one end of the vertical plate portion, the bottom horizontal plate portion and the top horizontal plate portion are distributed on both sides of the vertical plate portion, and the detection sensor is fixed on the top horizontal plate portion.
[0012] As described above, the slender component curvature detection device involved in the utility model has the following beneficial effects:
[0013] In the present application, after the slender component falls into the blanking trough of the blanking component, it is determined whether the bending of the slender component exceeds the standard by determining whether several detection sensors arranged in a straight line along the length direction of the slender component have detected the slender component: when several detection sensors all detect the slender component, it is determined that the curvature of the slender component is within the acceptable range, the slender component is qualified, and can flow into the subsequent production process; when one or more of the several detection sensors do not detect the slender component, it is determined that the curvature of the slender component exceeds the acceptable range, the slender component is unqualified, and at this time, the slender component can be disposed of as waste.

[0030] The present application provides a slender component curvature detection device, which is used to detect whether the curvature of the slender component exceeds the standard, that is, to detect whether the curvature of the slender component is within an acceptable range. In the following embodiment, the slender component curvature detection device is used in the field of prefabricated pile production and manufacturing. At this time, the slender component is a fixed-length steel rod 50 cut by a fixed-length cutting machine. At the same time, for the convenience of description, the length direction of the steel rod 50 is defined as the front-to-back direction.
[0031] like Figure 1 and Figure 2 As shown, the slender component curvature detection device involved in the present application includes a plurality of blanking components 10 and a plurality of detection sensors 20. Each blanking component 10 is provided with a blanking groove 11 for accommodating a steel rod 50. The plurality of blanking components 10 are arranged in a straight line front to back along the length direction of the steel rod 50. The plurality of detection sensors 20 are also arranged in a straight line front to back along the length direction of the steel rod 50. The detection sensors 20 are used to detect whether there are steel rods 50 around them.
[0032] When rolling the main reinforcement cage of the prefabricated pile, a fixed-length cutting machine is first used to process several fixed-length steel bars 50. The blanking component 10 is distributed directly below the output end of the fixed-length cutting machine, and the steel bars 50 cut by the fixed-length cutting machine fall into the blanking trough 11 of the blanking component 10 under the action of gravity. Afterwards, it is determined whether the steel bar 50 is bent beyond the standard by whether several detection sensors 20 arranged in a straight line along the length direction of the steel bar 50 detect the steel bar 50. When several detection sensors 20 all detect the steel bar 50, it is determined that the curvature of the steel bar 50 is within the acceptable range, the steel bar 50 is qualified, and can flow into the subsequent production process; when one or more of the several detection sensors 20 do not detect the steel bar 50, it is determined that the curvature of the steel bar 50 exceeds the acceptable range, the steel bar 50 is unqualified, and the steel bar 50 can be discharged for waste treatment. Therefore, the present application can well detect whether the curvature of the steel rod 50 exceeds the standard, and discard the steel rod 50 that fails the bending test, thereby preventing the fixed-length steel rod 50 that exceeds the bending standard from entering the subsequent production process, thereby avoiding subsequent processing equipment failures, and also effectively improving the quality of the formed cage reinforcement.
[0033] Preferably, the slender component curvature detection device further includes a buzzer, an indicator light, a display screen and a control cabinet, and the plurality of detection sensors 20, the buzzer, the indicator light and the display screen are all connected to the control cabinet in communication. When the control cabinet determines that the curvature of the steel bar 50 exceeds the acceptable range according to the output signal of the data detection sensor 20, the control cabinet triggers the buzzer and the indicator light, and displays the alarm information on the display screen. At the same time, the buzzer sounds an alarm and the indicator light turns on, thereby reminding the workers on site to remove the current steel bar 50 in the blanking chute 11 to complete the waste treatment.
[0034] Furthermore, there are many types of detection sensors 20; in this embodiment, the detection sensor 20 is a proximity switch sensor, which can be triggered by the steel rod 50. When the steel rod 50 is located in the blanking chute 11, as shown in FIG. Figure 1 and Figure 2 As shown, the sensing end of the proximity switch sensor is distributed directly below the steel rod 50.
[0035] Furthermore, if Figure 1 and Figure 2 As shown, the blanking component 10 is a V-shaped component, and the blanking groove 11 is a V-shaped groove, so the plurality of proximity switch sensors and the groove bottoms of the plurality of V-shaped grooves are aligned front and back. In this way, the cut steel rod 50 can slide downward along the inclined inner wall of the V-shaped component to the bottom of the V-shaped groove, and the inclined groove walls on the left and right sides of the V-shaped groove play a certain buffering role, and the V-shaped groove itself plays a certain limiting role, limiting the left and right movement of the steel rod 50 that slides to the bottom of the V-shaped groove.
[0036] Furthermore, if Figure 1 As shown, a plurality of blanking components 10 are arranged at equal intervals front to back, a plurality of proximity switch sensors are arranged at equal intervals front to back, and at least one proximity switch sensor is provided between two adjacent blanking components 10 . Figure 1 In the embodiment shown, a proximity switch sensor is provided between two adjacent blanking parts 10, that is, several blanking parts 10 and several proximity switch sensors are distributed at intervals. In a specific embodiment, in the front-to-back direction, the spacing between two adjacent proximity switch sensors is 1000 mm, and the diameter of the proximity switch sensor detection area is 30 mm, then the angle A of the steel rod 501m is: tanA = 30 / 2 / 1000 = 0.015, and the angle A of the steel rod 501m is obtained to be ≈ 1°. Therefore, in this embodiment, unqualified steel rods 50 with a bending degree exceeding 1° can be detected, so that the unqualified steel rods 50 are discharged, avoiding subsequent equipment failure problems and product quality problems. Of course, in other embodiments, proximity switch sensors of other specifications can also be selected, and the spacing between two adjacent proximity switch sensors can be set to other values, thereby controlling the detection accuracy.
[0037] Furthermore, if Figure 1 and Figure 2As shown, the slender component curvature detection device also includes a plurality of flip drive sources 30, each blanking component 10 can rotate around the same rotation center axis parallel to the steel rod 50, and the plurality of flip drive sources 30 correspond to the plurality of blanking components 10 one by one and are transmission-connected to drive the blanking components 10 to rotate. In this embodiment, the flip drive source 30 is a cylinder, and the rotation center axis of the steel rod 50 is distributed on the lower left side of the bottom of the blanking trough 11. The flip drive source 30 drives the blanking component 10 to rotate around the rotation center axis, so that the steel rod 50 in the blanking trough 11 can be tilted out, which is convenient for the transfer operation of the steel rod 50.
[0038] Furthermore, the installation structure of the plurality of detection sensors 20 is preferably: Figure 1 and Figure 2 As shown, the slender component curvature detection device also includes a plurality of sensor fixing brackets 40 that are fixedly arranged and correspond one-to-one to a plurality of detection sensors 20. The sensor fixing bracket 40 includes a bottom horizontal plate portion 41, a vertical plate portion 42 that is bent upward and extended from the left end of the bottom horizontal bracket, and a top horizontal plate portion 43 that is bent horizontally to the left and extended from the upper end of the vertical plate portion 42. The bottom horizontal plate portion 41 and the top horizontal plate portion 43 are distributed on the left and right sides of the vertical plate portion 42, and the detection sensor 20 is fixed on the top horizontal plate portion 43.
[0039] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
