Description

Technical Field

[0001] The invention belongs to the field of water electrolysis hydrogen production equipment, and in particular relates to an automatic cutting machine for cutting a nickel mesh of an electrolytic cell and a cutting method thereof. Background Art

[0002] The core components of the electrolyzer mainly include end pressure plates, large insulating plates, three major parts, plates, nickel mesh and diaphragm cloth. Due to the low gas production and small number of chambers of traditional electrolyzers, less nickel mesh is required in the production process. The cutting of nickel mesh is mainly done manually. This method of cutting nickel mesh is time-consuming and labor-intensive, which increases the production cost of electrolyzer equipment and limits the development of hydrogen energy to a certain extent. With the rapid development of hydrogen energy, traditional small electrolyzers can no longer meet the current market demand, and large electrolyzers have gradually become a major trend in the future development of electrolyzers.

[0003] Compared with small electrolytic cells, large electrolytic cells have a higher gas production per unit time and a larger volume, which results in an increase in the number of small chambers, an increase in the diameter of the nickel mesh, and an increase in the number of nickel meshes required for a single electrolytic cell. The traditional manual method of cutting the nickel mesh is no longer suitable for the production of existing large electrolytic cells. Summary of the invention

[0056] Use the control panel 9 to start the lifting reducer 10 to move the chassis 4 downward and press the nickel mesh evenly on the workbench 5.

The method of cutting using the above-mentioned cutting machine is as follows:

[0059] When the cutting operation is in progress, when the middle disc 17 is selected, the control panel 9 is used to start the lifting reducer 10, so that the chassis 4 moves downward, and the nickel mesh is evenly pressed on the workbench 5. The slider 15 on the tool bar arm 13 is adjusted to move the tool holder 3 to the middle disc 17, and the slider 15 is fixed with bolts, and the hob is fixed to the tool holder 3 with bolts. The control panel 9 is used to start the spindle reducer 1, and the tool bar arm 13 on the tool bar 2 is driven to rotate to complete the cutting of the nickel mesh.

Since the height of the second outer disc is lower than the middle chassis 17, the hob is fixed on the second row of bolt holes on the rectangular groove 16 of the tool holder 3. The control panel 9 is used to start the spindle reducer 1, and the tool bar arm 13 on the tool bar 2 is driven to rotate to complete the cutting of the nickel mesh.

[0061] When the size of the trimmed nickel mesh is reduced and the first outer disc is needed, start the lifting reducer 10 to move the chassis 4 upward, remove the stepped structure on the second outer disc and the first outer disc, take out the second outer disc with a large size, start the lifting reducer 10 to move the chassis 4 downward, press the nickel mesh evenly on the workbench 5, adjust the slider 15 on the tool bar arm 13 to move the tool holder 3 to the position of the first outer disc, and fix the slider 15 with bolts.
