Description

Technical Field

[0001] This utility model belongs to the field of nickel starting sheet processing technology, and relates to a nickel starting sheet lifting lug processing device. Background Technology

[0002] In the nickel electrolytic refining process, the starting electrode sheet needs to be riveted with two conductive lugs before being inserted into the electrolytic cell to produce electrolytic nickel. The lugs are made by cutting thin, uniformly thick nickel sheets. Currently, to improve efficiency, many companies use substandard starting electrode sheets to cut and support the lugs. The thickness of these lugs is 2 to 3 times that of the specially produced thin nickel sheets for lugs, with fluctuations reaching ±1mm. If traditional riveting heads are used during processing, the large variation in nickel sheet thickness leads to significant tension variations between the two riveting holes, easily causing stress concentration at the riveting head neck and subsequent breakage. Furthermore, due to the high elasticity and brittleness of the nickel sheet, the riveted edges may break during bending, resulting in unstable riveting quality, lug detachment, and loose riveting, leading to increased contact resistance during electrolysis and affecting the final product quality. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where stress concentration during the riveting of nickel starter sheet lifting lugs easily leads to rivet head breakage, and to provide a nickel starter sheet lifting lug processing device.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A nickel starting sheet lifting lug processing device includes a guide rod, one end of which is detachably mounted with two rivet head bodies. Each rivet head body includes a rod portion and an end portion with a quadrangular prism structure. The end portion includes a first end face and a second end face with an isosceles triangle structure. The first end face and the second end face are arranged opposite to each other. The base angle of the first end face is smaller than that of the second end face. Each side of the first end face is provided with a side end face with a triangular structure.

[0006] Furthermore, one end of the guide rod along its length is provided with two locking grooves that are adapted to the rod portion. The rod portion is located in the locking grooves. The side wall of the guide rod is provided with a screw hole, which passes through the locking groove. The rod portion is provided with a through hole corresponding to the screw hole. A bolt is provided in the screw hole, and the bolt passes through the through hole.

[0007] Furthermore, a guide groove is provided between the first end face and the guide rod.

[0008] Furthermore, the guide groove has an arc-shaped structure.

[0009] The beneficial effects of this utility model are as follows: setting the end of the rivet head body as a four-sided pyramid structure can effectively prevent the rivet head neck from breaking due to large tension changes between the nickel sheet rivet holes of the lifting lug during the riveting process, thus effectively improving the riveting quality and extending the service life of the rivet head; setting a guide groove between the end and the rod can effectively prevent the nickel sheet from breaking due to the pressure of the rod when it is turned over; the structure is simple and the cost is low.

[0015] The present invention will now be described in detail with reference to the accompanying drawings:

[0016] like Figure 1-4As shown, a nickel starting sheet lifting lug processing device includes a guide rod 1. Two rivet head bodies are detachably mounted on one end of the guide rod 1 along its length. The guide rod 1 can be installed on a corresponding device, and the rivet head bodies are moved by the guide rod 1 to perform riveting. The rivet head body includes a rod portion 2 and an end portion 3 with a quadrangular prism structure. The end portion 3 is fixed to one end of the rod portion 2 along its length. The rivet head body can be installed on the guide rod 1 through the rod portion 2, and the rivet head body can be moved by the guide rod 1 to complete the riveting. Specifically, one end of the guide rod 1 along its length is provided with two locking grooves 4 that are adapted to the rod portion 2. The rod portion 2 is located in the locking grooves 4, and the end portion 3 is located outside the locking grooves 4. The side wall of the guide rod 1 is provided with screw holes 5, which pass through the locking grooves 4. The rod portion 2 is provided with through holes 6 corresponding to the screw holes 5. Bolts 7 are provided in the screw holes 5. The bolts 7 are internal hex head bolts, and bolts 8 pass through the through holes. The rod 2 is fixed in the locking groove 4 of the guide rod 1 by bolt 7 through the bolt 6. A countersunk hole can be set at one end of the bolt hole 5 so that the end of the bolt 7 is located in the countersunk hole. The end 3 is used to press and fold the punched hole to complete the riveting. The end 3 includes a first end face 301 and a second end face 302 in the shape of an isosceles triangle. The first end face 301 and the second end face 302 are arranged opposite to each other. The base angle of the first end face 301 is smaller than the base angle of the second end face 302. Each side of the first end face 301 is provided with a side end face 303 in the shape of a triangle (that is, a side end face 303 is formed between the first end face 301 and the second end face 302). Setting the end 3 as a quadrangular prism structure can effectively prevent stress concentration at the end 3 of the rivet head during the riveting process, thereby preventing the rivet head from breaking. During installation, the first end faces 301 of the two rivet head bodies are arranged opposite to each other.

[0017] To prevent the nickel sheet at the riveting joint from breaking during bending, an arc-shaped guide groove 8 is provided between the first end face 301 and the second end face 302 and the rod 2. The guide groove 8 is located at the end of the rod 2. When the end of the nickel sheet enters the guide groove 8, it can be flipped under the action of the guide groove to prevent one end of the rod 2 from squeezing the nickel sheet, causing the nickel sheet to break and affecting the riveting quality.

[0018] The method of using this utility model is as follows:

[0019] First, punching operations are performed at the corresponding positions of the nickel starting sheet and the lifting lug using appropriate equipment to form rivet holes. During the pressing process, the first end face 301 and the second end face 302 of the end 3 contact the nickel sheet at the rivet hole and apply external force, causing the nickel sheet to rotate. When the end of the nickel sheet enters the guide groove 8, the nickel sheet continues to rotate, effectively preventing the end of the nickel sheet from being squeezed against the end of the rod 2 and causing breakage. After the nickel sheet is flanged, the lifting lug can be riveted to the nickel starting sheet.

[0020] The rivet head end 3, which adopts a quadrangular prism structure, can effectively prevent the end 3 from breaking due to stress caused by uneven thickness of the lifting lug nickel sheet during the riveting process, thus effectively improving the service life of the rivet head and the riveting effect.
