[0032] In actual use, the tube 100 is first placed on the sliding forming positioning seat for positioning, and then the driving mechanism 5 drives the sliding forming support seat 4 to move toward the fixed forming seat 3 to realize the forming of the cylindrical groove, and then the metal sphere 2 is placed in the tube 100, and then the extrusion mechanism 6 drives the metal sphere 2 to punch the tube 100, so that the side wall of the tube 100 is opened.

[0033] In the above design, the lateral through hole of the tube 100 can be effectively realized, and the burrs at the opening of the tube 100 after forming are easy to deal with, and the tube 100 will not be easily deformed during the forming process.

[0034] Specifically: Figure 3 and Figure 4 As shown, the sliding forming support seat 4 includes a sliding plate 41 which is slidably connected to the upper end surface of the frame 1, a No. 1 lateral fixing plate 42 which is arranged on the side of the sliding plate 41 away from the fixed forming seat 3, and a positioning column 43 which is arranged on the sliding plate 41. When the tube 100 is positioned by the positioning column 43, the positioning column 43 is coaxial with the tube 100, and the outer wall of the positioning column 43 is against the inner wall of the tube 100. When the metal sphere 2 is placed in the tube 100 positioned by the positioning column 43, it is supported by the positioning column 43. The No. 1 lateral fixing plate 42 is provided with a No. 1 semicircular groove 401 for positioning the outer wall of the tube 100.

[0035] In actual use, the pipe 100 is positioned by the positioning column 43. The positioned pipe 100 abuts against the No. 1 semicircular groove 401. The driving mechanism 5 drives the sliding plate 41 to move toward the side of the fixed forming seat 3, so that the sliding plate 41 drives the positioning column 43 and the No. 1 lateral fixed plate 42 to move synchronously.

[0036] In the above design, the structural design and specific implementation of the sliding forming seat can effectively realize the support and movement of the pipe 100.

[0037] Specifically: Figure 3 As shown, the fixed forming seat 3 includes a fixed block 31 fixedly arranged on the frame 1 and a No. 2 lateral fixing plate 32 fixedly arranged on the side of the fixed block 31 relative to the sliding forming support seat 4, the No. 2 lateral fixing plate 32 is provided with a No. 2 semicircular groove 301 for positioning the outer wall of the pipe 100, the No. 1 semicircular groove 401 and the No. 2 semicircular groove 301 form the cylindrical groove, the No. 1 through hole 320 connected to the semicircular groove is provided on the No. 2 lateral fixing plate 32, and the metal sphere 2 can flow into the No. 1 through hole 320.

[0038] In actual use, the fixed forming seat 3 is fixed on the frame 1. When the sliding forming support seat 4 drives the tube 100 to move toward one side of the fixed forming seat 3 and forms a cylindrical groove through the No. 1 semicircular groove 401 and the No. 2 semicircular groove 301, the fixed forming seat 3 and the sliding forming support seat 4 complete the fixation of the tube 100 and the preparation before punching. Then, the metal sphere 2 is squeezed out of the tube 100 into the No. 1 through hole 320 by the extrusion mechanism 6.

[0039] In the above design, the structural design and specific implementation method of the fixed forming seat 3 can effectively realize the recovery of the metal sphere 2.

[0040] Specifically: Figure 2 As shown, a clearance gap 302 is provided between the lower end of the second lateral fixing plate 32 and the upper end surface of the frame 1 , and the sliding plate 41 can extend into the clearance gap 302 and abut against the fixing block 31 .

[0041] In actual use, when the sliding forming support seat 4 and the fixed forming seat 3 are closed, the sliding plate 41 extends into the avoiding gap 302 .

[0042] In the above design, the structural design and specific implementation of the avoidance gap 302 can effectively realize setting the size of the sliding plate 41 to be larger, thereby meeting the installation requirements of the positioning column 43 and the pipe 100.

[0043] Specifically: Figure 2 and Figure 4As shown, the extrusion mechanism 6 includes a bracket 61 fixedly arranged on the frame 1, a No. 1 cylinder 62 arranged on the bracket 61 with the output end facing downward, and a punch 63 fixedly arranged at the output end of the No. 1 cylinder 62. The lower end of the punch 63 is provided with an inclined surface for extruding the metal sphere 2. The punch 63 can be inserted into the pipe 100 to extrude the metal sphere 2 using the inclined surface. After the punch 63 is inserted into the pipe 100, the cylindrical outer wall of the punch 63 is concentric with the cylindrical inner wall of the pipe 100 and is slidably connected.

[0044] In actual use, after the tube 100 is fixed by the fixed forming seat 3 and the sliding forming support seat 4, the punch 63 is driven downward by the No. 1 cylinder 62, so that the inclined surface of the punch 63 contacts the outer wall of the metal sphere 2 located in the tube 100. As the punch 63 continues to move downward, the metal sphere 2 is squeezed by the inclined surface, and finally the metal sphere 2 breaks through the tube 100 to complete the punching.

[0045] In the above design, the structural design and specific implementation of the extrusion mechanism 6 can effectively realize the rapid punching and forming of the metal sphere 2.

[0046] Specifically: Figure 1 As shown, the driving mechanism 5 includes a mounting seat 51 fixedly arranged on the frame 1 and a No. 2 cylinder 52 fixedly arranged on the mounting seat 51 along the X direction, and the output end of the No. 2 cylinder 52 is fixedly connected to the sliding molding support seat 4.

[0047] During actual use, the output end of the No. 2 cylinder 52 extends to drive the sliding molding support seat 4 to move toward the fixed molding seat 3, and the output end of the No. 2 cylinder 52 contracts to drive the sliding molding support seat 4 away from the fixed molding seat 3.

[0048] In the above design, the structural design and specific implementation of the driving mechanism 5 can effectively realize the rapid and stable movement of the sliding forming carrier 4.

[0050] In actual use, when the metal sphere 2 breaks through the tube 100 and enters the No. 1 through hole 320 , it flows into the No. 2 through hole 310 , and then flows out of the No. 2 through hole 310 into the fenced area 7 .

[0051] In the above design, the design and specific implementation of the second through hole 310 and the fence 7 can enable the metal sphere 2 to be recycled.

[0052] Specifically: Figure 2 As shown, a guide column 8 is further provided between the sliding molding support seat 4 and the fixed molding seat 3 , one end of the guide column 8 is fixedly connected to the fixed molding seat 3 , and the other end of the guide column 8 is slidably connected to the sliding molding support seat 4 .

[0053] In actual use, when the sliding molding support 4 moves relative to the fixed molding support 3 , the guide column 8 guides the sliding molding support 4 .

[0054] In the above design, the design and specific implementation of the guide column 8 can effectively guide the sliding forming support seat 4 and the fixed forming seat 3.

[0055] Specifically: Figure 1 and Figure 2 As shown, a start button 9 is provided on the bracket 61 , and the fence 7 is located in front of the start button 9 .

[0056] In the above design, by pressing the start button 9, the pressing action of the extrusion mechanism 6 is realized. When the pipe 100 is fixed by the sliding forming support seat 4 and the fixed forming seat 3, the metal sphere 2 recovered in the fence 7 is placed into the pipe 100 to be punched.

[0057] In the above design, the design and specific implementation of the start button 9 and the fence 7 can improve the convenience of operation.
