Background

The repair method of the worn working surface of the extrusion die for the existing extrusion honeycomb type products such as a honeycomb type ceramic heat accumulator, a honeycomb type SCR catalyst, a honeycomb type ceramic carrier and the like comprises the following steps: chemical nickel plating method. The method mainly uses hypophosphite as a reducing agent to deposit a layer of nickel-phosphorus alloy with the thickness (single-side thickness) of 0.01-0.1 mm on the surface of the die so as to achieve the purpose of repairing the size of the die. The chemical nickel plating method repairs the disadvantages of the extrusion die: 1. insufficient wear resistance of the plating layer: for example, after a honeycomb SCR catalyst extrusion die repaired by a chemical nickel plating method is used for producing a product of 50-70 cubic meters, the working surface of the die is seriously abraded and needs to be repaired again; 2. the quality stability is poor: because the quality of the chemical nickel plating is influenced by factors such as the environmental temperature, the temperature of the plating solution, the concentration of the plating solution, the cleanliness of the plating solution, the operation process and the like, the quality of the die repaired by the chemical nickel plating is unstable. If the honeycomb type SCR catalyst extrusion die repaired by the chemical nickel plating method is used, only 2-3 sets of the die can meet the production requirement if 10 sets of the die are repaired; 3. the waste liquid causes great pollution to the environment: because the chemical components of the plating solution for chemical nickel plating are complex, waste liquid with great pollution to the environment can be generated in the process of repairing the die, and the waste liquid can be discharged after being treated.

In conclusion, in order to overcome the defects in the prior art, a honeycomb type product extrusion die with a simple structure and good wear resistance needs to be designed.
