[0038] A method for manufacturing an inlaid riveted aluminum block, the process flow is as follows: Figure 7 As shown, it includes a first material strip 4 and a second material strip 5. In the direction of the first material strip 4 being fed forward, there are respectively provided a punching guide hole station 100, a punching first cutting edge hole station 101, a punching center hole station 102, a punching second cutting edge hole station 103, an inlay station 104, a forming step station 105, a forming protrusion and groove station 106, a blanking station 107, and a waste material 8 removal station 108.
[0039] The material belt is sent into the stamping equipment to be continuously conveyed to the blanking direction in a continuous step-by-step manner, and the blanking is sequentially performed on the first material belt 4 through the corresponding blanking die to form the material belt base on the first material belt 4. The thickness of the material belt base is 0.4 mm. The second material belt 5 is arranged above the first material belt 4. The first material belt 4 and the second material belt 5 are arranged in vertical interlacing. The second material belt 5 is arranged above the inlaying station 104 of the first material belt 4. When the first material belt 4 reaches the inlaying station 104, the product 7 blank punched out from the second material belt 5 falls onto the material belt base of the first material belt 4, and then subsequent operations are performed.
[0040] The manufacturing method of the inlaid riveted aluminum block specifically includes the following steps:
[0041] Step 1, edge cutting and punching: the first material belt 4 is sent into the stamping equipment. The edge cutting and punching are performed on the first material belt 4 during the forward feeding of the first material belt 4 to form the material belt base.
[0042] In step 1, the specific steps of edge cutting and punching are as follows:
[0043] Step 101, punching guide hole 4.1: the guide hole 4.1 is punched on the left side of the preformed product 7 blank during the forward feeding of the first material belt 4;
[0044] Step 102, punching first edge cutting hole 4.2: the first edge cutting hole 4.2 is punched on the left and right sides of the preformed product 7 blank during the forward feeding of the first material belt 4;
[0045] Step 103, punching center hole 4.3: the center hole 4.3 is punched at the preformed product 7 blank during the forward feeding of the first material belt 4;
[0046] Step 104, punching second edge cutting hole 4.4: the second edge cutting hole 4.4 is punched on the upper and lower sides of the preformed product 7 blank during the forward feeding of the first material belt 4.
[0047] Step 105, forming material belt base: after steps 102, 103 and 104, the material belt base is formed between the first edge cutting hole 4.2 and the center hole 4.3 and between the second edge cutting hole 4.4 and the center hole 4.3 on the first material belt 4.
[0048] After the edge cutting and punching of steps 101, 102, 103 and 104, four material belt bases are formed between the first edge cutting hole 4.2 and the center hole 4.3 and between the second edge cutting hole 4.4 and the center hole 4.3 on the first material belt 4. The material belt base can stably place the product 7 blank punched out on the second material belt 5 on the first material belt 4, and facilitate subsequent inlaying and riveting operations.
[0049] After step 102 and step 104, a deformation zone 4.5 is arranged between the first trimming hole 4.2 and the second trimming hole 4.4 formed on the first material strip 4, and a back-off amount of product 7 deformation is reserved through the deformation zone 4.5 to prevent the product 7 from being deformed by material expansion during subsequent forming, so as to affect the subsequent operation.
[0050] In step 103, the clearance area of the product 7 blank is cut out when the center hole 4.3 is punched out, so that the product 7 blank is only in contact with the four riveting positions during the performance of step 2 and step 3. When the center hole 4.3 is punched out, the clearance of the product 7 is cut out to ensure that the product 7 blank is only in contact with the four riveting positions when it is riveted to the material strip base, preventing the product 7 blank from being damaged by friction between the product 7 blank and the first material strip 4, thereby affecting the final quality of the product 7.
[0051] Step 2, perform inlaying: during the forward feeding of the first material strip 4, the second material strip 5 also performs forward feeding, and the sub-mold punches out the product 7 blank on the second material strip 5, continuously punches down and inlays onto the underlying first material strip 4, so that the product 7 blank is placed on the material strip base of the first material strip 4.
[0052] The second material strip 5 is placed above the first material strip 4, and the lower end surface of the product 7 blank punched out by the second material strip 5 abuts against the material strip base, and the abutting area of the product 7 blank and the material strip base forms a riveting position.
[0053] Step 3, perform riveting: during the forward feeding of the first material strip 4, the circular step 7.2 below the product 7 blank is formed by stamping, and the four riveting positions are embedded into the product 7 blank by under-pressing the product 7 blank and the four riveting positions to complete riveting. The front recess 7.1 and the back protrusion 7.3 of the pre-formed product 7 blank are formed, and the surrounding of the product 7 blank is half-cut.
[0054] The specific steps of riveting the product 7 blank are as follows:
[0055] Step 301, form the step 7.2: during the forward feeding of the first material strip 4, the circular step 7.2 is formed on the side of the product 7 blank away from the second material strip 5 by stamping, and at this time, the product 7 blank and the four riveting positions are continuously under-pressed to rivet the copper-aluminum joint of the product 7 blank;
[0056] Step 302, form the recess 7.1: during the forward feeding of the first material strip 4, the recess 7.1 is formed on the side of the product 7 blank away from the second material strip 5, and the protrusion 7.3 is formed on the side close to the second material strip 5, and at this time, the product 7 blank and the four riveting positions are further under-pressed to further rivet the copper-aluminum joint of the product 7 blank;
[0057] Step 303, semi-cutting: during the feeding of the first material strip 4, semi-cutting is performed around the product 7 blank.
[0058] As shown in Figure 8 and Figure 9 After the above steps, the two layers of the product 7 blank can be better riveted together, and when the forming step 7.2, the protrusion 7.3 and the groove 7.1 are formed, the riveting effect between the product 7 blanks can be further improved, thereby improving the final quality of the product 7.
[0059] When the forming step 7.2 is formed, the product 7 blank is subjected to interference pressing, and the material strip base always abuts against the lower end surface of the product 7 blank; during the traveling riveting, the double-layer product 7 blank is riveted together by interference pressing, and the material strip base always abuts against the lower end surface of the product 7 blank, so that an upward reaction force is generated at the riveting position during the pressing, and the product 7 blanks are better riveted together.
[0060] Step 4, blanking: during the feeding of the first material strip 4, the product 7 blank is cut to form the product 7 shape to obtain the final product 7.
[0061] The area of the product 7 shape cut during the final blanking is smaller than the area of the product 7 blank during the inlaying.
[0062] Step 5, waste 8 cutting: after the blanking of the product 7, the waste 8 is obtained on the first material strip 4, and the waste 8 is cut off.
[0063] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above embodiment. Any technical solution falling within the scope of the present application is within the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, some improvements and decorations without departing from the principles of the present application are also considered as the protection scope of the present application.
