The molding mechanisms correspond one to one with four positions of the shell 19 required for flanging for installing the axle. The molding mechanism includes a molding die slidably connected to the body 1 and a transmission component for driving the molding die to move to complete the flanging of the shell 19.

[0023] The machine body 1 includes a horizontal base 11 and a guide post 12 disposed on the base 11 .

[0024] There are four groups of molding mechanisms in total. The molding dies in each group of molding mechanisms include a molding convex mold 2 and a molding concave mold 3. The molding convex mold 2 and the molding concave mold 3 are arranged opposite to each other and are slidably connected to the base 11. Figure 3 The forming convex die 2 includes a forming rod 21 and a piercing rod 22 connected to one end of the forming rod 21 close to the forming die 3. The center lines of the forming rod 21 and the piercing rod 22 are on the same straight line. The cross-section of the forming rod 21 is larger than that of the piercing rod 22. Before flanging, the hole groove on the shell is just engaged with the piercing rod 22. The forming rod 21 pushes part of the shell toward the side of the forming die 3 to form an outward flanging.

[0025] Reference Figure 2 and Figure 3The forming punch 2 is fixedly connected with a punch slider 4, and the punch slider 4 is fixedly connected to one end of the forming rod 21 away from the penetration rod 22. The punch slider 4 includes a mounting block 41 and a moving block 42 fixedly connected to the bottom of the mounting block 41. Two oppositely arranged limiting guide rails 5 are fixedly installed on the base 11, and the length direction of the two limiting guide rails 5 is parallel to the sliding direction of the forming punch 2. The two limiting guide rails 5 are arranged on both sides of the width direction of the moving block 42 to limit and guide the sliding direction of the moving block 42.

[0026] The bottom of the forming die 3 is fixedly connected with a die slider 6, and one end surface of the forming die 3 facing the forming convex die 2 is provided with a forming cavity 31 for cooperating with the forming convex die 2. In order to allow the die slider 6 to move, a clearance groove 421 is provided along the length direction thereof on the moving block 42, and the die slider 6 is slidably connected in the clearance groove 421 along the length direction of the penetration rod 22.

[0027] In order to enable the transmission assembly to drive the forming punch 2 and the forming die 3 to move toward each other, the transmission assembly includes a driving slider 71 slidably connected to the machine body 1 in the vertical direction, and a transmission slider 72 fixedly connected to the driving slider 71. The driving slider 71 is slidably connected to the guide column 12, and the driving slider 71 moves in the vertical direction. During the actual processing process, the driving slider 71 can be driven to rise and fall by a hydraulic cylinder.

[0028] The transmission slider 72 is fixedly connected to the bottom surface of the driving slider 71. The two vertical side walls of the transmission slider 72 opposite to each other along the sliding direction of the forming die are respectively provided with a first driving inclined surface 721 and a second driving inclined surface 722.

In order to match the second driving inclined surface 722, a push block 20 is fixedly connected to the end of the moving block 42 away from the mounting block 41. The push block 20 is provided with a convex driving inclined surface 201 that matches the second driving inclined surface 722 on the side facing the second driving inclined surface 722. When the driving slider 71 drives the transmission slider 72 to move downward in the vertical direction, the die slider 6 is driven to move by the first driving inclined surface 721, and the convex slider 4 is driven to move by the second driving inclined surface 722, so that the forming die 3 and the forming convex 2 move toward each other, thereby completing the flanging action of the product.

[0029] In order to reset the forming die 3 and the forming punch 2 after the transmission slider 72 rises, a reset bar 23 is fixedly installed on the forming die 3, and both ends of the reset bar 23 are connected to a die reset member 8. The die reset member 8 is made of a spring, and a fixed column 24 is hooked at one end of the die reset member 8 away from the reset bar 23. The fixed column 24 is fixedly connected to the limiting guide rail 5, and the central axis of the die reset member 8 remains parallel to the length direction of the limiting guide rail 5.

[0030] An end plate 10 is fixedly installed between the ends of the two limit guide rails 5 away from the mounting block 41, and the length direction of the end plate 10 is parallel to the length direction of the limit guide rail 5. A sliding column 13 is fixedly connected to the end surface of the moving block 42 away from the mounting block 41 and is penetrated and slidably connected to the end plate 10. The axial direction of the sliding column 13 is parallel to the length direction of the limit guide rail 5. There are a total of 4 sliding columns 13, which form a group of two, and an adjusting bolt 14 threadedly connected to the end plate 10 is arranged between every two sliding columns 13. The outer sleeve of the adjusting bolt 14 A punch reset member 9 is provided, and a spring is selected for the punch reset member 9. Both ends of the punch reset member 9 are fixedly connected with a push plate 15. The push plate 15 close to the end plate 10 abuts against two sliding columns 13 in a group, and the push plate 15 away from the end plate 10 abuts against the bottom end surface of the end of the adjusting bolt 14. Therefore, after the transmission slider 72 rises, the punch reset member 9 drives the moving block 42 and the forming punch 2 to move away from the end plate 10 through the sliding column 13, so that the forming punch 2 and the forming die 3 are separated from each other, and the flanging-completed product can be taken out.

[0031] In order to keep the product stable during the flanging process, the positioning mechanism includes a support member for supporting the shell, a clamping member that can move in the vertical direction and cooperates with the support member to clamp the shell, and the support member includes two groups of support blocks 16 respectively used to abut the inner top wall of the shell near the front and rear wheel axles, and a support disc 17 used to abut the central circular hole of the shell. Both the front and rear groups of support blocks 16 can include multiple curved blocks that match the shape of the inner top wall of the shell. The bottom of the support disc 17 is fixedly installed on the base 11, and the support disc 17 abuts the bottom of the circular hole opened in the center of the shell.

[0032] The clamping member includes a clamping cylinder 181 connected to the driving slider 71 and a clamping block 182 connected to the output shaft of the clamping cylinder 181.
