Description

Technical Field

[0001] This utility model relates to the field of electrolyte cleaning technology, specifically to a shearing composite tool for residual electrode pressure stripping. Background Technology

[0002] In electrolytic aluminum production, the anode consists of a guide rod and an anode. A steel claw is located at the front end of the guide rod to fix the anode. After electrolysis, residual anode remains on the steel claw. Currently, a shearing-type residual anode press is commonly used to dismantle the residual anode, which uses upper and lower blades to shear the residual anode, causing it to break. However, the shearing effect of the upper and lower blades in existing technology is not ideal; the residual anode is not easily sheared, and the blades wear out easily. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a shearing composite tool for residual electrode pressing and stripping, which can improve residual electrode shearing efficiency and reduce wear on the upper and lower tools.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a shearing composite tool for residual electrode debonding, comprising an upper tool and a lower tool arranged opposite to each other, the upper tool having an L-shaped structure and an upper cutting edge at the bottom, the lower tool comprising a base and a lower blade body mounted on the base, the lower blade body having a zigzag lower cutting edge, the zigzag lower cutting edge being divided into a low cutting edge section and a high cutting edge section and arranged obliquely upward.

[0005] The low-cutting edge and the high-cutting edge are transitioned by rounded corners.

[0006] The lower blade has reinforcing ribs evenly distributed on both sides.

[0007] The front end of the upper cutting tool is chamfered.

[0008] The upper cutting edge and the zigzag lower cutting edge are coated with wear-resistant welding rods.

[0009] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model sets a zigzag-shaped lower cutting edge on the lower cutting tool and uses the height difference between the high cutting edge and the low cutting edge to distribute the shearing force that was originally concentrated at one point or one line to different stages and positions, effectively reducing the force on the entire cutting surface, forming staged shearing, thereby improving shearing efficiency and reducing tool wear.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0015] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments. Example

[0016] like Figures 1 to 2 As shown, this utility model provides a shearing composite tool for residual electrode pressing and stripping, including an upper tool 1 and a lower tool 2 arranged opposite to each other. The upper tool 1 has an L-shaped structure and an upper cutting edge 11 is provided at the bottom. The lower tool 2 includes a base 21 and a lower blade 22 mounted on the base 21. The lower blade 22 is provided with a zigzag lower cutting edge 221, which is divided into a low cutting edge section 2211 and a high cutting edge section 2212 and is inclined upward.

[0017] By utilizing the height difference between the low-cutting section 2211 and the high-cutting section 2212 in the zigzag-shaped lower cutter 221, the shearing force that was originally concentrated at one point or along one line is distributed to different stages and positions, effectively reducing the force on the entire blade surface, forming staged shearing, thereby improving shearing efficiency and reducing the wear of the upper cutter 1 and the lower cutter 2.

[0018] Specifically, the low-cutting section 2211 and the high-cutting section 2212 are transitioned by rounded corners. The rounded corner transition can reduce stress concentration and improve the durability of the lower tool 2.

[0019] Specifically, reinforcing ribs 23 are evenly distributed on both sides of the lower blade 22. During the shearing process, the lower blade 22 needs to withstand large shearing forces and impact forces. The presence of reinforcing ribs 23 can effectively disperse these forces and prevent the lower blade 2 from being damaged due to stress concentration.

[0020] Specifically, the upper cutter 1 has a chamfer at its front end. The chamfer is provided to facilitate the upper cutter 1 entering the guide rod gap for guidance.

[0021] Specifically, in order to improve the wear resistance of the upper cutting tool 1 and the lower cutting tool 2 and extend the tool service life, wear-resistant welding rods are deposited on the upper cutting edge 11 and the zigzag lower cutting edge 221.

[0022] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
