TECHNICAL FIELD

[0001] The utility model relates to the technical field of heat shield edge covering, in particular to an engine heat shield edge covering die. BACKGROUND

[0002] The engine heat shield edge covering die is a specially designed tool used to cover the edges of the engine heat shield during the manufacturing process. This die bends the edge material of the heat shield and covers it to the other side by applying pressure, forming a closed edge, enhancing the structural strength, sealing performance, and aesthetics of the heat shield. It is a key link in the production of engine heat shields.

[0003] Currently, during the edge covering process of the engine heat shield, left and right clamps are commonly used to fix and hold the heat shield, thereby improving the quality of edge covering. This method can ensure the accuracy and consistency of edge covering to a certain extent. However, existing clamps have certain limitations in design and use. These clamps often lack adjustment structures. When the engine heat shield is subjected to uneven pressure during the edge covering process, the clamps cannot be adjusted accordingly, which not only leads to a decrease in edge covering accuracy but also may be damaged due to excessive pressure, resulting in wrinkles, distortion, or gaps. Therefore, an engine heat shield edge covering die is proposed. SUMMARY

[0004] To overcome the shortcomings of the prior art, the utility model provides an engine heat shield edge covering die, which has the advantages of improving the quality of engine heat shield edge covering, and solves the problem of uneven pressure on the engine heat shield during the edge covering process, which cannot be adjusted accordingly, resulting in a decrease in edge covering accuracy and possible damage due to excessive pressure, resulting in wrinkles, distortion, or gaps.

A clamping plate is fixedly installed on the top outer wall of the connecting seat. A limit sliding rod is fixedly installed on the outer walls of opposite sides of the two adjusting clamping seats.

[0007] Furthermore, three pressure detectors are fixedly installed inside the clamping plate, with the detection end of the pressure detector located on the side of the clamping plate away from the rubber plate.

[0008] Furthermore, the support side plate has a threaded hole inside, a limit hole inside, an adjusting threaded rod is threadedly connected inside the threaded hole and is of a suitable size, and a limit sliding rod is slidably connected inside the limit hole and is of a suitable size.

[0009] Furthermore, the reinforcing frame is X-shaped, and the mounting plate is fixedly installed on the side of the reinforcing frame closest to the adjusting spring, away from the adjusting spring.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This engine heat shield edging mold uses an adjustable threaded rod and a limiting slide rod to adjust the clamping seat. An electric telescopic rod, connecting seat, clamping plate, and pressure detector clamp the engine heat shield and detect and adjust the position of the clamping plate. The mounting plate, adjusting spring, and rubber plate absorb the pressure generated during the edging process, ensuring the heat shield remains stable and preventing deformation or damage due to uneven pressure.
