[0054] Example 2

[0055] In order to solve the problem of how to improve the processing accuracy of the edge drawing wheel in the prior art and improve the forming quality of the glass ribbon, the second aspect of this embodiment provides an edge drawing wheel, see Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.12 , Fig.14 , Fig.15 The hemming wheel obtained by the above-mentioned hemming wheel processing equipment also includes a mounting shaft, a gear ring is fixed at the end of the mounting shaft, an end panel 1 is fixed inside the gear ring, a water dividing plate 2 is installed at the end of the end panel 1, a mounting plate 3 is installed at the end of the water dividing plate 2, and a pipe sleeve 4 is installed on the central axis of the mounting plate 3.

[0056] In this embodiment, the first fixture 7, the second fixture, the third fixture and the wire-cut toothed fixture 100 are used for processing, and the processing involves the whole process of processing the workpiece in the blank state into the edge drawing wheel. The specific processing steps are as follows:

[0057] In the first step, the steel plate is cut by laser automatic cutting equipment, and parts are processed according to the prefabricated shape to obtain the formed water distribution plate 2, the installation plate 3, the pipe sleeve 4 and the end panel 1.

[0058] Specifically, prepare the blank to be processed in advance, place it on the processing table and fix it, select the electrode wire of suitable diameter and material according to the required size and shape, and then set the appropriate cutting parameters according to the material and thickness of the blank, including discharge current and discharge time, install the electrode wire in the wire cutting machine's wire pulley, and adjust the cutting parameters on the control panel of the wire cutting machine, including the distance between the cutting head and the blank, and finally cut the blank.

[0059] According to the above cutting operation steps, the water divider plate 2 can be processed first, and then Figure 5 The shape of the middle water divider 2 is set with corresponding parameters of the wire cutting machine tool, and a rectangular water divider 2 with a protruding portion is obtained; Figure 6 The mounting plate 3 is then processed, and the corresponding parameters are set on the machine tool according to the shape of the mounting plate 3, so as to obtain a circular mounting plate 3 with a central through hole and a plurality of grooves 31 along the outer circumference. Figure 7 Processing sleeve 4 and according to Figure 8 The end panel 1 is processed, and the corresponding parameters are set on the machine tool to obtain a pipe sleeve 4 with a stepped through hole inside and a stepped shaft 41 outside, and an end panel 1 with a stepped circular plate. The processing sequence of the water divider 2, the mounting plate 3, the pipe sleeve 4 and the end panel 1 can be adjusted according to the size of the specific plate and the specific needs, and is not limited to the above processing sequence. In this embodiment, it is necessary to strictly control the concentricity of the pipe sleeve 4 and the end panel 1, and a vernier caliper, a manual image measuring instrument, a roundness measuring instrument, a three-coordinate measuring machine, a fully automatic image measuring instrument and other equipment can be used for detection. In addition, the coaxiality of the stepped through hole of the pipe sleeve 4 must be ensured, and the optional setting range is 0-0.1mm.

[0060] For the second step, please refer to Figure 1 , Fig.11 , Fig.12 , the water distribution plate 2, the mounting plate 3 and the pipe sleeve 4 are positioned by the first fixture 7, and the water distribution plate 2, the mounting plate 3 and the pipe sleeve 4 are welded together. The specific processing steps are as follows:

[0061] The center hole 32 of the mounting plate 3 is sleeved on the positioning core 72 of the clamp, and the protrusion of the water diversion plate 2 is clamped into the groove 31 of the mounting plate 3; wherein, the main body of the water diversion plate 2 is a rectangular plate, and the protrusion is a trapezoidal plate; the mounting plate 3 is evenly provided with a plurality of grooves 31 along the circumferential direction, and the corresponding water diversion plate 2 should also be multiple, which can be 8 different numbers, and the specific number can be set according to specific needs. The side of the water diversion plate 2 is fixed with the fixing piece which is the clamp limiting concave platform 73, and the fixing piece which is the clamp cover plate 71 is pressed and fixed with the top of the water diversion plate 2, wherein it can be fixed with bolts, and then the welding operation is performed. The joint between the water diversion plate 2 and the mounting plate 3 can be welded first, and then the external stepped shaft 41 of the pipe sleeve 4 is welded to the end face close to the center hole 32 of the mounting plate 3 to obtain the water diversion plate assembly. In addition, in the prior art, after the edge drawing wheel processing is completed, a stepped through hole 42 is drilled in the pipe sleeve 4. When the pipe sleeve 4 is processed, a stepped through hole 42 is provided inside. While ensuring the coaxiality of the through hole of the pipe sleeve 4, drilling before machining prevents iron filings from remaining in the inner cavity of the water dividing plate 2 and being unable to be cleaned, affecting the use of the product, thereby improving the processing accuracy.

[0062] In the prior art, during the process of welding the hemming wheel, the end panel 1 is prone to be dented and deformed, resulting in insufficient machining allowance of the outer dimensions. The hemming wheel obtained by the machining method of the utility model avoids the occurrence of the above situation.

[0063] The third step is to weld the water distribution plate assembly to the end panel 1. The specific processing steps are as follows:

[0064] Please refer to Figure 3 , Figure 4 , Fig.13 , using the third fixture in the above embodiment, place the base 81 on the bottom of the end panel 1, and fix the stepped outer circular plate of the end panel 1 to the fixture;

[0065] Place the water distribution plate assembly on the end plate 1, and place the circumferential surface of the pipe sleeve 4 in the fixture;

[0066] The water distribution plate 2 and the end panel 1 are gap welded to obtain an end panel assembly.

[0067] Specifically, the fixture in the processing steps of this embodiment can take the form of a V-shaped block, the bottom of the end panel 1 is placed on the base 81, the stepped outer circular plate of the end panel 1 is tightly fitted on the first V-shaped block 82, and then the end of the water dividing plate 2 in the water dividing plate assembly is placed on the end panel 1, and the second V-shaped block 83 is tightly fixed through the circumferential surface of the pipe sleeve 4 connected thereto, and the coaxiality between the pipe sleeve 4 and the step of the end panel 1 is adjusted, and the joints of the water dividing plate 2 and the end panel 1 are welded. In addition, the end panel assembly obtained by the above-mentioned clamping and installation method has a complete structure, and the processing allowance can meet the preset requirements.

[0068] Conventional processing methods for the gear ring 5 mainly involve turning. Since the gear ring 5 has a thin wall, a small clamping contact surface, and is prone to vibration, the processing quality is poor. The processing of the gear ring 5 adopted by the present invention avoids the problems existing in conventional methods.

[0069] The fourth step is to process the gear ring 5 and the mounting shaft 6. The specific processing steps are as follows:

[0070] Please refer to Fig.14 , Fig.15 , prepare steel parts, lathes, cutting tools and auxiliary tools in advance, fix the steel parts to the lathe tool holder by clamping and chucks, select corresponding turning tools according to the drawings of the gear ring 5 and the mounting shaft 6 to be processed, including rough turning tools, cutting tools, wheels and other tools, set turning parameters for the machine tool, including parameters such as the tool holder movement speed, feed speed and axial depth of the lathe.

[0071] The steel part to be processed is turned to obtain a gear ring 5, wherein the two ends of the gear ring 5 have different diameters, and the curved surface formed outwardly at the large-diameter end extends to the small-diameter end, and the gear ring 5 is provided with a space for accommodating an end panel assembly; in addition, the turning process of the gear ring 5 needs to strictly ensure the coaxiality of the cavity and each step hole relative to the center. In addition, since the wall thickness of the gear ring 5 is relatively thin and the clamping contact area is small, a process clamping reference fixture is added in this embodiment, which is set close to the curved surface of the gear ring 5 to ensure turning stability, thereby improving the processing quality of the gear ring 5.

[0072] Another steel part to be processed is turned to obtain the installation shaft 6, which includes a plurality of turned stepped shafts 41, wherein the shaft diameter of the stepped shaft 41 can be set to be gradually decreased, and the aperture of the center hole 32 of the stepped shaft 41 is consistent, and the smallest stepped shaft 41 on the installation shaft 6 is assembled with the small-diameter gear ring 5.

[0073] The fifth step is to weld the end panel assembly, the gear ring 5 and the mounting shaft 6. The specific processing steps are as follows:

[0074] Please refer to Figure 2 , Fig.16, use the second clamp for assembly welding to obtain the welded edge wheel, more specifically, weld the matching grooves of the mounting shaft 6 and the gear ring 5 to obtain a welded assembly, and place the welded assembly on the clamp, and the center hole 32 of the mounting shaft 6 can be fixed to the clamp limit block 93, and the bottom surface of the mounting shaft 6 fits with the surface of the clamp base, and then the end panel assembly is placed in the space provided with an accommodation space on the gear ring 5, and fixed with the internal circumferential groove 31; an auxiliary pressing plate 92 is set on the end surface where the end panel assembly and the gear ring 5 cooperate, and the area of ​​the auxiliary pressing plate 92 is larger than the area outside the gear ring 5, and an external force is applied to press the auxiliary pressing plate 92, and the gear ring 5 and the end panel assembly are welded, wherein the external force applied can be a rotary pressing cylinder 91, and rotary pressing cylinders 91 can be respectively set at both ends of the auxiliary pressing plate 92 of the gear ring 5, so as to further improve the pressing effect of the auxiliary pressing plate 92, thereby improving the welding air tightness of the gear ring 5 and the end panel assembly.

[0075] The sixth step is to perform fine turning on the installation shaft 6, gear ring 5 and end panel assembly after installation and welding. The specific processing steps are as follows:

[0076] Please refer to Fig.17 , 18 , set a spacer 60 in the hole of the stepped shaft 41 near the end of the gear ring 5; and turn the edge wheel according to a certain precision. Here, before turning and clamping, set a spacer 60 in the hole of the stepped shaft 41 to prevent iron filings from the inner hole of the axle from entering the inner cavity of the edge wheel. The spacer 60 here can be a plugged polyurethane plug. After turning, use a pin puller to pull out the plug.

[0077] The seventh step is to cut the edge wheel. The specific processing steps are as follows:

[0078] Please refer to Figure 5 , Figure 6 , Fig.19 , 20 This embodiment uses the wire cutting toothed fixture 100 in the above embodiment to process the edge drawing wheel after assembly welding. First, the electrode wire is wound, and then the height of the wire rack is adjusted according to the thickness of the edge drawing wheel, the wire is tightened and the verticality of the electrode wire and the workbench is corrected. Next, the center line is drawn, and a wire threading hole 101 is prefabricated. The edge drawing wheel is correctly placed at a suitable position on the mounting table. The cutting range of the edge drawing wheel should be within the stroke allowed by the machine tool, and the edge drawing wheel and the fixture should not touch any part of the wire rack during the cutting process. The reference is aligned, the program is transferred to the processing lathe, and processing is performed according to a certain processing route to obtain the edge drawing wheel after wire cutting tooth shape.
