Description

Technical Field

[0001] The utility model relates to the technical field of embedded structural parts for rail transit, in particular to a punching device for embedded channel filling strips. Background Art

[0002] The filling strips in the embedded channel are usually made of foam materials, such as polyethylene filled square strips or foam strips, which are characterized by light weight, heat preservation, sound insulation, and good waterproof performance. During construction, it is necessary to process positioning holes on the filling strips. At present, the positioning holes of the embedded channel filling strips are usually made by electric heating.

[0003] Before processing, the filling strip must be installed inside the groove, and then electric heating is used to burn the hole. The positioning hole after heating in this way is irregular in shape, which affects the accuracy of the later embedded groove and the positioning bolt of the pipe segment. Moreover, the positioning hole of the filling strip is electrically heated, and the positioning hole of the groove is too small. The surface coating of the groove is easily burned during the heating and burning process of the electric soldering iron. In addition, the filling strip is electrically heated, and the packaging personnel need to place the workpiece in advance (with the anchor part facing downward), press the filling strip into the groove, and then flip the groove 180°. After adjusting the groove positioning hole to the top, the electric soldering iron is used to heat the hole, resulting in high labor intensity, low packaging efficiency, and high labor costs.

Figure 2 , Figure 4 As shown, the punching assembly 1 includes a driving mechanism and a punch 14, the driving mechanism is installed on the fixed block 21 and can drive the punch 14 to pass through the punching hole; the ruler 6 is installed on one side of the fixed block 21 and is parallel to the positioning groove, the supporting assembly 3 is arranged on both sides of the fixed block 21 and the back side of the ruler 6, and the top surface of the supporting assembly 3 is flush with the bottom surface of the groove 22 of the fixed block 21.

[0031] When punching, first place one end of the filling strip 4 into the positioning groove and move from right to left. The first hole spacing is positioned using the left end face of the filling strip 4. One end of the filling strip 4 is moved to the corresponding position of the ruler 6. Press the punching switch to perform the punching process. The second hole is positioned using the first hole, and so on for the processing of other holes.

[0032] The utility model adopts a filling strip punching device to replace the original electric heating hole processing, and the filling strip 4 can be punched in advance, without filling the inside of the groove and then burning the hole. The pre-punching makes the processing operation of the filling strip positioning hole convenient, and there is no need for the packaging personnel to repeatedly place and transport the workpiece, which reduces the handling waste and improves the production efficiency. In addition, the filling strip punching device is used to punch the positioning hole, replacing the original electric heating hole, and the positioning groove and the ruler 6 greatly improve the processing accuracy of the filling strip positioning hole. The punching size of the filling strip 4 is accurate, which is consistent with the size and precision tolerance of the groove positioning hole, solves the problem of the irregular hole type of the original electric heating hole, and improves the matching accuracy of the later embedded groove positioning hole and the pipe segment positioning bolt. In addition, the filling strip punching device is used to punch the positioning hole, replacing the original electric heating hole, which avoids the problem of scalding the groove surface coating during the electric soldering iron heating hole.

[0033] like Figure 3As shown, the fixing block 21 is C-shaped, and the groove 22 is formed in the middle of the C-shaped fixing block 21. The positioning bar 24 is detachably installed in the groove 22 of the fixing block 21 and is located at the outer end of the groove 22. There are two positioning bars 24, which are arranged in parallel, and there is a set distance between the two positioning bars 24 to form a positioning groove, and the positioning groove is perpendicular to the groove 22. The cross-sectional shape of the positioning groove formed by the two positioning bars 24 in the filling bar punching device matches the cross-sectional shape of the filling bar 4, ensuring the processing accuracy of the filling bar positioning hole position and avoiding deviation or size out-of-tolerance.

[0034] A through hole is provided on the fixed block 21 at the bottom side of the groove 22, and the through hole is aligned with the positioning groove.

[0042] 2. The positioning holes are punched by the filling strip punching device instead of the original electric heating holes, and the positioning groove and the ruler 6 are used to greatly improve the processing accuracy of the filling strip positioning holes. The punching size of the filling strip 4 is accurate, which is consistent with the size and precision tolerance of the slot positioning hole, solving the problem of the irregular hole type of the original electric heating, and improving the matching accuracy of the later embedded slot positioning holes and the positioning bolts of the pipe segments.

[0043] 3. Use a filling strip punching device to punch positioning holes instead of the original electric heating holes, avoiding the problem of scalding the groove surface coating during the electric soldering iron heating process.
