Technical realization elements of flanging press-fit tooling for metal heat shield of automobile catalytic converter

Technical realization elements:

4. The purpose of this utility model is to provide a flanging press-fitting tool for the metal heat shield of automobile catalytic converters, which can solve the problem of sealing seams in the metal heat shield of automobile catalytic converters due to technical reasons. There are several vertical flanges left on the side. If they are not processed, it will affect the installation of the metal heat shield on the car. Usually, the flanging is hammered manually with a hammer, and then the car is installed after being flattened. However, a metal heat shield construction worker usually needs to hammer for about 20 minutes, which is labor intensive, slow in work speed, and low in work efficiency. The high cost of enterprises is not conducive to large-scale, large-scale production activities.

5. In order to solve the above technical problems, the present utility model is realized through the following technical solutions:

6. The utility model is a flanging press-fitting tool for the metal heat insulation cover of automobile catalytic converter, which includes a large bottom plate, and the upper surface of the large bottom plate is fixedly installed with a first bracket, a second bracket, two gpf support plates and a number of heat insulation Cover support plate. The heat shield support plate is located on the right side of the gpf support plate. The catalytic converter is placed on the surface of the gpf support plate. The two sides of the catalytic converter are fixedly installed with pipes. The right side of the catalytic converter is wrapped with a catalytic converter heat shield. The heat shield of the catalytic converter is located on the upper surface of the support plate of the heat shield. The heat shield of the catalytic converter is composed of upper and lower shells. The two sides of the lower shell are extended with seam edges, and the upper surface of the seam edge is extended with flanged bosses. After the upper shell is buckled on the upper surface of the lower shell, the exposed part is welded together with the pipe by resistance welding, and the flanged boss on the sealing edge of the lower shell is pressed to the upper surface of the upper shell to match , The front end of the heat shield support plate is fixedly installed with fastening screws, and the upper surface of the fastening screws is fixedly installed with high-strength hinges. The high-strength hinges are matched with the heat shield of the catalytic converter by pressing. The device is fixed on the ground so that the construction personnel can use the device better and improve the stability; by setting high-strength hinges to push and cooperate with the heat shield of the catalytic converter, it is convenient for the construction personnel to quickly flatten the flanging and dispose of the original A metal heat shield needs fifteen minutes to be shortened to two minutes, which is conducive to reducing the labor intensity of construction personnel, increasing work speed, reducing enterprise costs, and enabling large-scale and large-scale production activities.

7. Preferably, a first pressure clamp is installed on the upper surface of the first bracket, and the first pressure clamp is matched with the catalyst by pressing. By installing the first pressure clamp on the upper surface of the first bracket, it is convenient to fix the catalyst, which is beneficial to The staff can better carry out the construction.

8. Preferably, a second pressure clamp is installed on the upper surface of the second bracket, and the second pressure clamp is matched with the heat shield of the catalytic converter by pressing, and the second pressure clamp is installed on the upper surface of the second bracket to facilitate fixing of the catalytic converter The heat shield is conducive to the better construction of the staff.

9. Preferably, the front end surface of the high-strength hinge is welded with a handle, and the handle and the high-strength hinge are matched by pushing and pulling.

10. Preferably, a flange flange is welded on the upper surface of the seam sealing edge, and the flange flange is perpendicular to the seam sealing edge. The flange flange is pressed by a high-strength hinge to become flat and fits the seam edge.

11. Preferably, a connecting plate is fixedly installed at one end of the left pipe of the catalytic converter, and a connecting plate is fixedly installed at one end of the right pipe of the catalytic converter. By providing the connecting plate, it is beneficial for the metal heat shield of the automobile catalytic converter to be better than other parts of the automobile. The connection installation improves the car adaptability of the metal heat shield of the car catalytic converter.

12. This utility model has the following beneficial effects:

13.1. The utility model can well fix the device on the ground by setting a large bottom plate, which is convenient for construction personnel to use the device better and improve stability; by setting a high-strength hinge to push and cooperate with the heat shield of the catalytic converter, it is convenient The construction personnel quickly flattened the flanging, shortening the original 15 minutes to two minutes to process a metal heat shield, which is beneficial to reduce the labor intensity of the construction personnel, increase the work speed, reduce the cost of the enterprise, and can carry out large-scale and large-scale Mass production activities.

14.2. By providing the connecting plate, the utility model facilitates the better connection and installation of the metal heat shield of the automobile catalytic converter with other parts of the automobile, and improves the car adaptability of the metal heat shield of the automobile catalyst.

15. Of course, any product implementing the present utility model does not necessarily need to achieve all the advantages described above at the same time.
