Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a cutting device for formwork in building engineering. Background Technology

[0002] In formwork construction, formwork cutting is a critical process. It often requires cutting the formwork at different angles (such as vertical, 45°, etc.) according to design requirements to meet splicing and installation needs. Existing traditional formwork cutting devices generally suffer from the following problems:

[0003] Inconvenient angle adjustment: The angle positioning structure of most cutting equipment is fixed or the adjustment is complicated. It requires manual measurement with the aid of a protractor or repeated calibration through complex bolts, clips and other structures. The operation is time-consuming and the accuracy is difficult to guarantee.

[0004] Insufficient flexibility: Some devices only support fixed angles (such as the default vertical cutting). If special angles (such as 30°, 60°, etc.) are required, additional parts or external auxiliary tools are needed, resulting in poor versatility.

[0005] Low positioning accuracy: Traditional angle adjustment relies on manual experience or simple scales, lacking a reliable positioning benchmark. During the cutting process, factors such as vibration and uneven force can easily cause angle deviation, affecting the quality of template splicing.

[0006] To address the aforementioned issues, this invention utilizes a rotating connection structure between the angle positioning plate and the cutting table, along with angle indicator lines, positioning bolts, and multiple sets of positioning holes, to achieve rapid adjustment and precise positioning of the cutting angle. No additional measuring tools are required, and multiple preset angles can be switched as needed, significantly improving cutting efficiency and accuracy, and meeting the diverse template cutting needs in construction engineering.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A cutting device for formwork in construction engineering includes a cutting table and a reciprocating saw, wherein the upper surface of the cutting table is provided with an angle positioning component and a cutting guide component;

[0010] The angle positioning component includes an angle positioning plate. One end of the bottom surface of the angle positioning plate is rotatably connected to the upper surface of the cutting table via a mounting shaft. The upper surface of the cutting table is provided with an angle indicator line centered on the mounting shaft. A positioning bolt is threaded through the upper surface of the angle positioning plate. A positioning hole adapted to the positioning bolt is opened on the upper surface of the cutting table.

[0011] The cutting guide assembly includes a guide rail, the longitudinal extension line of the angle positioning plate is perpendicular to the transverse extension line of the guide rail, the base of the reciprocating saw is slidably connected to the inner wall of the guide rail, an auxiliary groove is provided at the bottom of the inner wall of the guide rail, and a cutting groove corresponding to the auxiliary groove is provided on the upper surface of the cutting table.

[0012] A further improvement of this utility model is that: the bottom end of the positioning bolt is threadedly connected to the inner wall of the positioning hole, a limiting wheel is fixedly connected to the outer wall of the reciprocating saw near the bottom end, and the limiting wheel is slidably connected to the inner wall of the guide rail.

[0013] A further improvement of this utility model is that: the bottom end of the reciprocating saw is provided with a saw blade, and the bottom end of the saw blade is inserted into the inner wall of the cutting groove.

[0014] A further improvement of this utility model is that: the bottom surface of the guide slide rail is detachably and fixedly connected to a slide rail pad by bolts, and the slide rail pad is fixedly connected to the upper surface of the cutting table.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] This utility model provides a cutting device for formwork in construction engineering. The angle positioning plate in the angle positioning assembly can rotate on the cutting table via a mounting shaft. Combined with an angle indicator line centered on the mounting shaft, positioning bolts, and positioning holes, the cutting angle can be easily adjusted. Positioning holes at different angles can be opened on the cutting table as needed to meet various cutting requirements. Whether cutting the side of the formwork perpendicularly or cutting at a specific angle, it can be easily achieved.

[0019] This utility model provides a cutting device for formwork in construction engineering. The guide rail of the cutting guide component provides a clear path for the movement of the reciprocating saw. The setting of the limiting wheel ensures that when the reciprocating saw moves laterally within the guide rail, the movement path always remains parallel to the guide rail, avoiding saw blade deviation during the cutting process, ensuring the accuracy of the cutting effect, and improving the cutting quality.

[0020] This invention provides a cutting device for formwork in construction engineering. The mounting shaft, using bolts as an axle, allows the angle positioning plate to be detached from the cutting table when not in use. The guide rail can also be quickly disassembled. This design facilitates the storage and transportation of the device, reduces space occupation, and also makes maintenance and component replacement convenient when needed.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] Example 1

[0029] like Figure 1-4 As shown, this utility model provides a cutting device for formwork in construction engineering, including a cutting table 1 and a reciprocating saw 6. The upper surface of the cutting table 1 is provided with an angle positioning component and a cutting guide component.

[0030] The angle positioning assembly includes an angle positioning plate 2. One end of the bottom surface of the angle positioning plate 2 is rotatably connected to the upper surface of the cutting table 1 via a mounting shaft 9. The upper surface of the cutting table 1 is provided with an angle indicator line 11 centered on the mounting shaft 9. The angle indicator line can be accurate to 1° as needed, using a numerical scale with a larger scale mark every 5° for easy angle reading by the operator. A positioning bolt 10 is threaded through the upper surface of the angle positioning plate 2, and a positioning hole 12 adapted to the positioning bolt 10 is provided on the upper surface of the cutting table 1. The positioning holes 12 are evenly distributed on the cutting table at 5° intervals, centered on the mounting shaft 9. For example, when cutting a 30° angle, the angle positioning plate 2 can be rotated until the positioning bolt 10 aligns with the positioning hole 12 corresponding to 30°.

[0031] The upper surface of the angle positioning plate 2 is threaded with a positioning bolt 10, and the upper surface of the cutting table 1 is provided with a positioning hole 12 that is compatible with the positioning bolt 10.

[0032] The cutting guide assembly includes a guide rail 3, the longitudinal extension line of the angle positioning plate 2 is perpendicular to the transverse extension line of the guide rail 3, the base of the reciprocating saw 6 is slidably connected to the inner wall of the guide rail 3, an auxiliary groove 15 is provided at the bottom of the inner wall of the guide rail 3, and a cutting groove 8 corresponding to the auxiliary groove 15 is provided on the upper surface of the cutting table 1.

[0033] The bottom end of the positioning bolt 10 is threaded to the inner wall of the positioning hole 12, and the outer wall of the reciprocating saw 6 near the bottom end is fixedly connected to the limiting wheel 14, which is slidably connected to the inner wall of the guide rail 3.

[0034] Example 2

[0035] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the bottom end of the reciprocating saw 6 is provided with a saw blade 13, and the bottom end of the saw blade 13 is inserted into the inner wall of the cutting groove 8.

[0036] The bottom surface of the guide slide rail 3 is detachably fixedly connected to the slide rail pad 4 by bolts, and the slide rail pad 4 is fixedly connected to the upper surface of the cutting table 1.

[0037] A handle 7 is fixedly connected to the outer wall of the reciprocating saw 6, and a plate clamping assembly 5 is provided on the side of the cutting table 1.

[0038] The working principle of the formwork cutting device for this construction project will be explained in detail below.

[0039] like Figure 1-4As shown, when cutting the template, the angle positioning plate 2 can be adjusted according to the desired shape. When the cutting path is perpendicular to the side of the template, the angle positioning plate 2 is kept perpendicular to the guide rail 3. At this time, one side of the template is placed against the side of the angle positioning plate 2, and then fixed on the cutting table 1 by the plate clamping assembly 5. Then, the reciprocating saw 6 is started, moving forward along the path of the guide rail 3, and the template is cut by the saw blade 13. At this time, the cutting path is perpendicular to the side of the template.

[0040] When it is necessary to adjust the angle between the cutting path and the side of the template, the positioning bolt 10 is removed and rotated around the mounting shaft 9. When the positioning bolt 10 aligns with the positioning hole 12, it has rotated exactly 45 degrees. Then, the template is moved back to the previous position to complete the cutting operation.

[0041] Positioning holes 12 at different angles can be made on the cutting table 1 as needed to meet different cutting requirements.

[0042] When the reciprocating saw 6 moves laterally along the inner wall of the guide rail 3, the limiting wheel 14 limits the movement of the reciprocating saw 6, so that the movement path of the reciprocating saw 6 always remains parallel to the guide rail 3, thereby ensuring the cutting effect.

[0043] The mounting shaft 9 can be installed using bolts as a shaft, allowing the angle positioning plate 2 to be disassembled from the cutting table 1 when not in use, and the guide rail 3 can also be quickly disassembled.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
