[0063] The material strip 300 includes a plurality of groups of plates 303, the punching assembly 204 punches, cuts and stamps the plates 303 on the material strip 300 to form the through hole 111 and the abutting piece 112, and each group of plates 303 is stamped into a planar support 301. The punching process acts on the center position of the plate 303. The cutting process and the stamping process act on the periphery of the center position of the plate 303 to stamp the mounting portion 11, the first side plate 2, the second side plate 3 and the fixing portion 4 on the base plate 1. The cutting process forms the first connecting arm 42 and the second connecting arm 43 which are not connected on the planar support 301; the cutting process acts on the connection between the center position of the plate 303 and the first connecting arm 42 and the second connecting arm 43 to cut the first stamping portion 421 on the first connecting arm 42; and the second stamping portion 431 is cut on the second connecting arm 43.

[0068] As shown in Figures 8 to 10 In the pressing process, in some embodiments, the bottom of the pressing member 2061 is provided with a pressing protrusion 2611 corresponding to the splicing position of the first stamping part 421 and the second stamping part 431. The pressing member 2061 is pressed to the splicing position of the first stamping part 421 and the second stamping part 431, and the pressing member 2061 continues to press to the pressing protrusion 2611 to form a stamping groove 5 at the splicing position.

[0069] In other embodiments, the bottom of the sliding block 2642 is provided with a pressing protrusion 2611 corresponding to the splicing position of the first stamping part 421 and the second stamping part 431. The pressing member 2061 is pressed to the splicing position of the first stamping part 421 and the second stamping part 431, and the pressing member 2061 continues to press to the pressing protrusion 2611 to form a stamping groove 5 at the splicing position.​

[0070] In other embodiments, the base 2062 is provided with a pressing protrusion 2611 corresponding to the joint of the first stamping part 421 and the second stamping part 431. The pressing rivet 2061 presses down the sliding block 2642 to drive the sliding block 2642 to move downward to abut the joint of the first stamping part 421 and the second stamping part 431. The pressing rivet 2061 continues to press down to form a stamping groove 5 at the joint by the pressing protrusion 2611 on the sliding block 2642.

[0071] Please refer to Figure 9 and Figure 10 In the present embodiment, the pressing rivet 2061, the sliding block 2642 and the two bases 2062 are all provided with two pressing protrusions 2611 corresponding to the joint of the first stamping part 421 and the second stamping part 431.

[0072] On the side close to the gap 113, the pressing rivet 2061 presses down to abut the joint of the first stamping part 421 and the second stamping part 431 on the same side. The pressing rivet 2061 continues to press down to form two stamping grooves 5 at the joint on the upper surface by the two pressing protrusions 2611 on the pressing rivet 2061, and to form two stamping grooves 5 at the joint on the lower surface by the two pressing protrusions 2611 on the base 2062. Each stamping groove 5 is located on the joint edge 4211, so that the first stamping part 421 and the second stamping part 431 are more tightly combined at the joint, thereby increasing the strength of the connection.

[0073] On the other side away from the gap 113, the pressing rivet 2061 presses down the sliding block 2642 to drive the sliding block 2642 to move downward to abut the joint of the first stamping part 421 and the second stamping part 431. The pressing rivet 2061 continues to press down to form two stamping grooves 5 at the joint on the upper surface by the two pressing protrusions 2611 on the sliding block 2642, and to form two stamping grooves 5 at the joint on the lower surface by the two pressing protrusions 2611 on the base 2062. Each stamping groove 5 is located on the joint edge 4211, preferably, the length of the stamping groove 5 is the same as or slightly greater than the length of the joint edge 4211, so that the stamping groove 5 can cover the joint edge 4211.

[0074] The pressing rivet assembly 206 is used to splice and rivet the first stamping part 421 and the second stamping part 431, and to form a stamping groove 5 at the joint, so that the first stamping part 421 and the second stamping part 431 can be firmly spliced without welding. Compared with the traditional manual welding of the first connecting arm 42 and the second connecting arm 43, the pressing rivet assembly 206 can complete the fixed connection of the first connecting arm 42 and the second connecting arm 43 during the assembly production, greatly improving the production efficiency and reducing the production cost, without manual welding.

[0075] Please refer toFigure 8 、 Figure 12 、 Figure 13 and Figure 14 As shown, further, when the rivet 2061 presses down the first connecting arm 42 and the second connecting arm 43, the pressing protrusion 2611 punches out a punching groove 5 at the joint of the first punching portion 421 and the second punching portion 431, which causes the joint to bulge. In order to improve this phenomenon, the rivet assembly 206 is provided with limiters 2063 on both sides of the length direction corresponding to the joint of the first punching portion 421 and the second punching portion 431. The limiters 2063 are arranged on both sides of the base 2062. The limiters 2063 press against both sides of the first connecting arm 42 and the second connecting arm 43 in the width direction to prevent the joint of the first connecting arm 42 and the second connecting arm 43 from being deformed under the action of external force, so that the limiters 2063 limit the width of the first connecting arm 42 and the second connecting arm 43 in the width direction.

[0076] The cutting assembly 209 is disposed in the upper die holder 201 and is located above the discharge port 208. The feeding assembly 203 delivers the plate 303 on the material strip 300 to the cutting assembly 209, which cuts off the connection between the mounting bracket 100 and the material strip 300, causing the mounting bracket 100 to fall into the discharge port 208.

[0077] See also Figures 4 to 17 As shown, the manufacturing process of the mounting bracket 100 is described below. In this embodiment, the mounting bracket 100 is manufactured by continuous stamping, which mainly includes the following steps:

[0079] The second process: the feeding component 203 transports the plate 303 on the material belt 300 to the stamping component 204, and the stamping component 204 stamps the plate 303 into a planar bracket 301, and stamps a first stamping portion 421 on the first connecting arm 42 of the planar bracket 301, and stamps a second stamping portion 431 on the second connecting arm 43 of the planar bracket 301.

[0080] The third step: the feeding assembly 203 transports the plate 303 to the forming assembly 205 , and the forming assembly 205 bends the flat bracket 301 into an X-shaped bracket 302 , and sets the first punching part 421 and the second punching part 431 in a stacked shape.

[0081] The fourth procedure: the feeding assembly 203 transports the plate 303 to the riveting assembly 206, and the riveting assembly 206 rivets the first stamping part 421 and the second stamping part 431 to splice in the same horizontal plane; and the pressing protrusion 2611 on the riveting assembly 206 forms the stamping groove 5 at the splicing position of the first stamping part 421 and the second stamping part 431.

[0082] The fifth procedure: the feeding assembly 203 transports the plate 303 on the material belt 300 to the cutting assembly 209, and the cutting assembly 209 cuts the connecting position between the mounting bracket 100 and the material belt 300, so that the mounting bracket 100 is discharged.

[0083] Preferably, the embodiment can add an empty step in any of the above procedures, so that there is enough space and time for adjustment between each working component (such as the feeding assembly 203, the stamping assembly 204, the forming assembly 205, the riveting assembly 206, and the cutting assembly 209, etc.), so as to avoid damage or failure caused by mutual interference between the working components.

[0084] The manufacturing process of the mounting bracket 100 is as follows:

[0085] Firstly, the material belt 300 is sent from the feeding port 207 to the feeding assembly 203, and is transported by the feeding assembly 203 to the next working position. Secondly, the stamping assembly 204 punches, forms, and cuts the plate 303 on the material belt 300 to form a planar bracket 301 with a first connecting arm 42 and a second connecting arm 43. The first connecting arm 42 and the second connecting arm 43 are cut to form a first stamping part 421 and a second stamping part 431, as shown in FIG. 4B. Figure 15 Thirdly, the feeding assembly 203 transports the plate 303 to the third procedure, and the forming assembly 205 bends the planar bracket 301 into a U-shaped bracket 302, and sets the first stamping part 421 and the second stamping part 431 in a stacked manner, as shown in FIG. 4C. Figure 16 In the fourth procedure, the riveting assembly 206 rivets the first stamping part 421 and the second stamping part 431 to splice in the same horizontal plane. Then, the feeding assembly 203 transports the plate 303 to the next working position, and the first stamping part 421 and the second stamping part 431 are riveted, and the pressing protrusion 2611 forms the stamping groove 5 at the splicing position of the first stamping part 421 and the second stamping part 431, as shown in FIG. 4D. Figure 17The riveting process: the first connecting arm 42 and the second connecting arm 43 are placed on the base 2062, wherein one riveting piece 2061 is pressed against the first connecting arm 42 and the second connecting arm 43 on the side close to the gap 113 to splice them in the same horizontal plane. The other riveting piece 2061 presses the slider 2642 downward to drive the slider 2642 to move downward to abut against the first connecting arm 42 and the second connecting arm 43 on the side away from the gap 113, and the slider 2642 is pressed against the first connecting arm 42 and the second connecting arm 43 to splice them in the same horizontal plane. The riveting process: on the side close to the gap 113, the riveting piece 2061 is pressed downward to abut against the splicing position of the first stamping part 421 and the second stamping part 431 on the same side. The riveting piece 2061 continues to be pressed downward, so that the two pressing protrusions 2611 on the riveting piece 2061 form two stamping grooves 5 at the splicing position of the upper surface, and at the same time, the two pressing protrusions 2611 on the base 2062 form two stamping grooves 5 at the splicing position of the lower surface. On the other side away from the gap 113, the slider 2642 is pressed downward by the other riveting piece 2061 to drive the slider 2642 to move downward to abut against the splicing position of the first stamping part 421 and the second stamping part 431. The riveting piece 2061 continues to be pressed downward to the splicing position of the two pressing protrusions 2611 on the slider 2642 to form two stamping grooves 5 at the upper surface, and at the same time, the two pressing protrusions 2611 on the base 2062 form two stamping grooves 5 at the splicing position of the lower surface.

[0086] In summary, the mounting bracket 100 is spliced and fixed by the first stamping part 421 and the second stamping part 431, so that the first connecting arm 42 and the second connecting arm 43 are fixedly connected to increase the connection strength of the mounting bracket 100. The splicing design of the protrusion and the groove makes the first connecting arm 42 and the second connecting arm 43 flat at the connection position without protruding parts, which improves the overall appearance of the product. In addition, the first connecting arm 42 and the second connecting arm 43 are fixedly connected without welding through the splicing of the protrusion and the groove, which simplifies the process and reduces the production cost.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
