Description

Technical Field

[0001] This application relates to the technical field of rebar marking, and in particular to a marking device for rebar. Background Technology

[0002] In the field of rebar quality inspection, marking devices are widely used to mark rebars to facilitate subsequent classification, identification, and management. With the increasing requirements for rebar quality inspection, higher demands are placed on the clarity, durability, and accuracy of rebar markings. Traditional marking technology plays an important role in the rebar processing flow, not only improving work efficiency but also providing a reliable basis for rebar quality traceability.

[0003] In existing technologies, dot marking machines are typically used to mark rebars. Dot marking machines create dot-shaped marks on the surface of the rebars through impact to meet basic marking requirements.

[0004] The aforementioned dot-marking machines suffer from unclear or easily erased markings. Especially during inspection, environmental factors or human error can cause the dot marks to become blurred or even disappear, making it difficult to identify the original gauge length of the rebar and affecting the acquisition of inspection data. Therefore, there is an urgent need for a device capable of providing clear and durable markings to address the shortcomings of existing rebar markings that are easily erased and insufficiently noticeable. Utility Model Content

[0005] In order to overcome the aforementioned defects, this application provides a marking device for reinforcing bars.

[0006] The marking device for reinforcing bars provided in this application adopts the following technical solution:

[0007] A marking device for reinforcing bars includes an upper mold and a lower mold. A scale is detachably connected to the upper mold, and multiple cutting slits corresponding to the scale positions on the scale are opened on the outer surface of the upper mold.

[0008] By adopting the above technical solution, the combined use of the upper and lower molds provides a stable working platform for marking rebars; the scale can be detachably connected to the upper mold for easy replacement and adjustment, and the scale on the scale corresponds one-to-one with the cutting position on the outer surface of the upper mold, ensuring the accuracy of marking at specific positions on the rebars; this design enables the marking device to accurately mark the rebars with lines, and compared with the existing dot marking, line marking has a clearer and more durable effect.

[0009] Preferably, the upper mold is provided with a positioning element that connects to the lower mold, and the positioning element enables the same end face of the upper mold and the lower mold to be flush.

[0010] By adopting the above technical solution, the positioning component enables the upper and lower molds to be precisely aligned, ensuring that their end faces are flush. This design effectively improves the stability of the marking device and reduces the problem of inaccurate marking caused by mold position deviation, thereby improving the accuracy and consistency of marking.

[0011] Preferably, the mold has horizontally extending extensions formed on opposite sides.

[0012] By adopting the above technical solution, the extension can increase the contact area between the lower mold and the table, ground or desktop, so that the lower mold can be placed more stably on the table, ground or desktop.

[0013] Preferably, the scale is detachably connected to the inclined surface of the upper mold via a locking component.

[0014] By adopting the above technical solution, the locking component allows the scale to be securely connected to the inclined surface of the upper mold, thus ensuring that the scale will not loosen or shift during use. At the same time, since the scale is detachably connected to the upper mold, it is easy to replace or adjust the scale, thus improving the flexibility and practicality of the marking device.

[0015] Preferably, the top surface of the lower mold and the bottom surface of the upper mold are provided with placement grooves for placing reinforcing bars.

[0016] By adopting the above technical solution, the placement grooves on the top surface of the lower mold and the bottom surface of the upper mold can be used to place the reinforcing bars, making the reinforcing bars more stable during the marking process and effectively reducing the displacement of the reinforcing bars during cutting; the placement grooves can also ensure that the relative position between the reinforcing bars and the upper and lower molds is fixed, thereby improving the accuracy of marking.

[0017] Preferably, the cross-section of the placement groove is V-shaped.

[0018] By adopting the above technical solution, on the one hand, the V-shaped cross-section placement groove can automatically adjust the contact point according to the diameter of the steel bar, ensuring that the steel bar will not shake during the marking process, thus improving the marking accuracy and stability; on the other hand, this design enables the marking device to adapt to steel bars of various sizes, enhancing the versatility and applicability of the device.

[0019] Preferably, the positioning element is fixedly connected to one end of the bottom surface of the upper mold, and a positioning groove corresponding to the position of the positioning element is provided on the top surface of the extension.

[0020] By adopting the above technical solution, the positioning components and positioning grooves enable the upper and lower molds to achieve precise positioning through the cooperation of the positioning components and positioning grooves, ensuring that the same end face of the two is flush. This design effectively improves the stability of the marking device and avoids marking errors caused by inaccurate alignment of the upper and lower molds, thereby improving the marking accuracy and reliability.

[0021] Preferably, there are two positioning elements, which are symmetrically arranged on the upper mold, and the number of positioning slots is consistent with the number of positioning elements and corresponds one-to-one.

[0022] By adopting the above technical solution, two symmetrical positioning components and corresponding positioning grooves are set up, making the positioning between the upper and lower molds more stable and accurate. This design effectively improves the stability of the marking device and effectively reduces the error caused by inaccurate positioning during the marking process, thereby ensuring that the line marks on the surface of the rebar are clearer, more obvious and less likely to be erased. In addition, the symmetrically set positioning components also improve the structural balance of the device and further enhance the reliability of operation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The combined use of the upper and lower molds provides a stable working platform for marking rebars; the scale is detachably connected to the upper mold for easy replacement and adjustment, and the scale on the scale corresponds one-to-one with the cut position on the outer surface of the upper mold, ensuring the accuracy of marking at specific locations on the rebars; this design enables the marking device to accurately mark the rebars with lines, and compared with the existing dot marking, line marking has a clearer and more durable effect;

[0025] 2. The V-shaped cross-section placement groove can automatically adjust the contact point according to the diameter of the reinforcing bar, ensuring that the reinforcing bar will not shake during the marking process, thus improving the marking accuracy and stability. On the other hand, this design allows the marking device to adapt to reinforcing bars of various sizes, enhancing the device's versatility and applicability.

[0026] 3. The design incorporates two symmetrical positioning components and corresponding positioning slots, resulting in more stable and precise positioning between the upper and lower molds. This design effectively improves the stability of the marking device and reduces errors caused by inaccurate positioning during the marking process, thereby ensuring that the line marks on the rebar surface are clearer, more obvious, and less likely to be erased. In addition, the symmetrically arranged positioning components enhance the structural balance of the device, further improving the reliability of operation. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a marking device for reinforcing bars. (Refer to...) Figure 1 and Figure 2 The marking device for steel bars includes an upper mold 1 and a lower mold 2. A scale 3 is detachably connected to the upper mold 1, and multiple cutting holes 11 corresponding to the scale positions on the scale 3 are opened on the outer surface of the upper mold 1. The upper mold 1 and the lower mold 2 are of equal length, and a positioning component connected to the lower mold 2 is provided on the upper mold 1. The positioning component can make the same end face of the upper mold 1 and the lower mold 2 flush.

[0033] The reinforcing bar is placed between the upper mold 1 and the lower mold 2, and the same end face of the upper mold 1 and the lower mold 2 is made flush by the positioning component. When it is necessary to mark a specific position on the reinforcing bar, the cutting part of the saw can be extended into the corresponding cutting opening 11, and the cutting part of the saw can be used to cut the surface of the reinforcing bar located between the upper mold 1 and the lower mold 2 to mark the surface of the reinforcing bar. Moreover, the mark is a line mark. Compared with the dot mark formed by the existing dot mark, the line mark is not easy to be erased and the mark is clearer and more obvious.

[0034] Reference Figure 2 and Figure 3 In this embodiment, the upper mold 1 and the lower mold 2 include, but are not limited to, iron blocks and stainless steel blocks, so that the upper mold 1 and the lower mold 2 have cutting parts that are more durable and resistant to cutting by knives and saws.

[0035] The lower mold 2 has horizontally extending extensions 21 formed on opposite sides, and the bottom surface of the extensions 21 is flush with the bottom surface of the lower mold 2. The extensions 21 can extend the contact area between the lower mold 2 and the table, ground or desktop, so that the lower mold 2 can be placed more stably on the table, ground or desktop.

[0036] The upper mold 1 has an isosceles trapezoidal cross-section, with the larger cross-sectional area facing downwards. A scale 3 is detachably connected to one inclined surface of the upper mold 1, with the side of the scale 3 closest to the upper mold 1 fitting against the inclined surface. The scale 3 is detachably connected to the inclined surface of the upper mold 1 via a locking member 31. One end of the locking member 31 passes through the scale 3 and is threadedly connected to the inclined surface of the upper mold 1, thus enabling the scale 3 to be detachably connected to the upper mold 1. To ensure a more secure installation of the scale 3 on the upper mold 1, two locking members 31 are provided, located at opposite ends of the scale 3. In this embodiment, the locking members 31 include, but are not limited to, screws and bolts.

[0037] The top surface of the lower mold 2 and the bottom surface of the upper mold 1 are provided with placement grooves 4 for placing reinforcing bars. The placement groove 4 on the lower mold 2 extends laterally through both end faces of the lower mold 2, and the placement groove 4 on the upper mold 1 extends laterally through both end faces of the upper mold 1, so that the ends of the reinforcing bars placed between the two placement grooves 4 can extend outside the upper mold 1. The cross-section of the placement groove 4 is V-shaped, so that the placement groove 4 can support reinforcing bars of different sizes, thereby realizing the marking of reinforcing bars of different sizes.

[0038] The positioning component is a positioning block 12, which is fixedly connected to one end of the bottom surface of the upper mold 1. A positioning groove 22 corresponding to the position of the positioning block 12 is provided on the top surface of the extension 21. When the positioning block 12 is inserted into the positioning groove 22, the end face of the upper mold 1 and the end face of the lower mold 2 are flush. To achieve better positioning, in this example, two positioning blocks 12 are provided, symmetrically arranged on the upper mold 1. The number of positioning grooves 22 is the same as the number of positioning blocks 12 and corresponds one-to-one.

[0039] The implementation principle of the marking device for reinforcing bars in this application embodiment is as follows: the upper mold 1 and the lower mold 2 cooperate to achieve stable clamping of the reinforcing bars; the setting of the scale 3 allows the user to accurately find the position of the reinforcing bars that need to be marked, and the design of the cutting opening 11 makes it easy for the cutting part of the saw to extend to the designated position, thereby realizing the line marking on the surface of the reinforcing bars; compared with the traditional dot marking, the line marking has the advantages of being less likely to be erased and the marking is clearer and more obvious. At the same time, through the design of the V-shaped placement groove 4, this device can adapt to reinforcing bars of different sizes, thus improving the applicability.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
