Description

Technical Field

[0001] This invention relates to the field of zinc removal devices, and particularly to a one-time rapid zinc removal device for anchor products. Background Technology

[0002] Currently, the main method for removing zinc deposits from hot-dip galvanized products is to use an angle grinder or hand file to grind the zinc deposits individually. Manual grinding is slow, the grinding effect is inconsistent, and it is very easy to damage the coating and grind down to the substrate, affecting the product's anti-corrosion performance.

[0003] refer to Figure 2 As shown, the top center of the product has a concave structure, and a protruding cylindrical block 5 is set in the center of the concave structure. Steel strip holes 6 are set on both sides of the groove for steel strips to pass through. Mounting holes 7 are also set around the product. Due to the complex structure of the product, zinc will accumulate at the cylindrical block, steel strip holes and mounting holes after hot-dip galvanizing, which requires manual polishing, which is inefficient.

[0004] Therefore, it is necessary to design a one-time rapid zinc removal device for anchor products to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a one-time rapid zinc removal device for anchor products, so as to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A one-time rapid zinc removal device for anchor products includes an upper mold mechanism and a lower mold mechanism corresponding to the upper mold mechanism. The upper mold mechanism includes an upper mold frame, an anchor zinc removal block located in the middle of the upper mold frame, and zinc removal shafts with mounting holes around the upper mold frame. The lower mold mechanism includes a lower template, a contour positioning plate on the lower template, an arc-shaped contour block on the contour positioning plate, zinc removal rods on both sides of the arc-shaped contour block to mate with the steel strip mounting holes at both ends of the product, and zinc removal holes with mounting holes corresponding to the zinc removal shafts of the mounting holes, respectively located around the contour positioning plate.

[0008] Preferably, guide posts are provided around both the upper mold mechanism and the lower mold mechanism, and a return spring is sleeved inside the guide posts. The top and bottom of the return spring support the two sides of the upper mold mechanism and the lower mold mechanism, respectively.

[0009] Preferably, the zinc removal block of the anchor protrusion has a groove.

[0010] The beneficial effects of this utility model are: the positioning block that conforms to the shape of the product is used to position the product, and the zinc removal shaft and slot are set at the position where zinc needs to be removed from the product to remove the zinc in the shaft and hole, thereby removing the zinc from the product in one go and greatly improving efficiency.

[0014] Reference Figure 1 and Figure 2 A one-time rapid zinc removal device for anchor products, comprising an upper mold mechanism 1 and a lower mold mechanism 2 corresponding to the upper mold mechanism;

[0015] The upper mold mechanism 1 includes an upper mold frame 11, an anchor protrusion zinc removal block 12 located in the middle of the upper mold frame, and a zinc removal shaft with mounting holes located around the upper mold frame.

[0016] The lower mold mechanism 2 includes a lower mold plate 21, a contour positioning plate 22 disposed on the lower mold plate 21, an arc-shaped contour block 23 disposed on the contour positioning plate, zinc removal rods 24 disposed on both sides of the arc-shaped contour block and used to cooperate with the steel strip mounting holes at both ends of the product, and zinc removal holes 25 disposed around the contour positioning plate and corresponding to the zinc removal shafts 13 of the mounting holes.

[0017] Guide posts 3 are provided around the upper mold mechanism 1 and the lower mold mechanism 2. A return spring 4 is sleeved inside the guide post. The top and bottom of the return spring support the two sides of the upper mold mechanism 1 and the lower mold mechanism 2, respectively.

[0018] The zinc removal block 12 is provided with a groove 14; the groove 14 is used to fit and interlock with the cylindrical block.

[0019] refer to Figure 2As shown, the top center of the product has a concave structure, and a raised cylindrical block 5 is set in the middle of the concave structure. Steel strip holes 6 are set on both sides of the groove for steel strips to pass through. Mounting holes 7 are also set around the product. Due to the complex structure of the product, zinc will accumulate at the cylindrical block, steel strip holes and mounting holes after hot-dip galvanizing, requiring manual polishing.

[0020] The working principle is as follows: the product is placed on the contour block, and the internal structure of the contour block fits and is fixed in place. The zinc removal rods 24 on both sides correspond to the steel strip holes on both sides. The mounting holes around the product correspond to the zinc removal holes 25 on the positioning block. After the product is positioned and installed, the mold is closed, and the upper mold mechanism presses down, causing the arc-shaped contour block 23 to press down. The arc-shaped contour block 23 is attached to the groove on the top of the product. At the same time, the cylindrical block at the top of the product groove is embedded in the groove 14. The zinc removal shafts 13 around the mounting holes are engaged with the mounting holes of the product and the zinc removal holes 25 on the positioning plate. After the top of the product is pressed and fits against the positioning block, the zinc removal shafts 13 of the lower mold mechanism move up and are engaged with the steel strip holes. In this way, the zinc in the cylindrical block, steel strip holes, and mounting holes of the product is removed in one go. Then the mold is opened. If there is residual zinc on the mold surface, it is cleaned with an air gun and the product is removed. The above work can be repeated.

[0021] The advantages of this utility model are that the positioning block that conforms to the shape of the product is used to position the product, and the zinc removal shaft and slot are set at the position of the product where zinc needs to be removed to remove the zinc in the shaft and the hole, thereby removing the zinc on the product in one go and greatly improving efficiency.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
