Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1-4 shown, a cooling pipe processing tooling includes a forming tooling and an upsetting tooling. The forming tooling includes a first mounting seat 1 and a first fixture 4. A flaring die 2 and a plurality of forming dies 3 are installed on one side of the first mounting seat 1 close to the first fixture 4. A first forming groove 15 is formed on one side of the forming die 3 close to the first fixture 4, and a core die 8 is arranged in the first forming groove 15. The first fixture 4 includes two first clamping blocks 7. A first mounting groove 5 is formed on the opposite sides of the two first clamping blocks 7, and a first positioning groove 6 is arranged on one side of the first mounting groove 5 close to the first mounting seat 1. As Figure 10 shown, a first positioning ring 33 is arranged on the cooling pipe 32. The cooling pipe 32 is placed in the first mounting groove 5 of one of the first clamping blocks 7, the first positioning ring 33 is placed in the first positioning groove 6, and the other first clamping block 7 is pressed on. The two first clamping blocks 7 are fixed relative to each other to clamp and fix the cooling pipe 32.

[0030] The flaring die 2 moves towards the first fixture 4, and the flaring die 2 flares the pipe end, causing the pipe to deform slightly and the diameter to increase.

[0031] The forming die 3 arranged from top to bottom moves towards the fixture one 4 in sequence, so that the pipe end enters between the core die 8 and the first forming groove 15. The core die 8 and the first forming groove 15 act together to extrude the pipe end, causing the pipe end to deform to form a flat mouth section 34 and a transition section 35, as Figure 11 shown. The widths of the first forming groove 15 and the core die 8 increase in sequence from top to bottom according to the installation position of the forming die 3, and the thicknesses of the first forming groove 15 and the core die 8 decrease in sequence from top to bottom according to the installation position of the forming die 3. Through multiple formations, the amount of deformation each time is smaller, and the cooling pipe 32 is not easily damaged due to severe deformation.

[0032] An introduction block 9 is arranged on one side of the core die 8 close to the fixture one 4. The diameter of one end of the introduction block 9 close to the core die 8 is larger than that of the end far from the core die 8. An introduction inclined surface 14 is arranged on one side of the first forming groove 15 close to the fixture one 4. The width of one end of the introduction inclined surface 14 close to the first forming groove 15 is smaller than that of the end far from the first forming groove 15. The arrangements of the introduction block 9 and the introduction inclined surface 14 form an open structure, enabling the pipe end to better enter between the core die 8 and the first forming groove 15.

[0033] A first fixing groove 13 is opened on one side of the first forming groove 15 far from the fixture one 4. A first fixing block 10 is connected to one side of the core die 8 far from the fixture one 4. The first fixing block 10 is arranged in the first fixing groove 13. A first through hole 12 is opened in the forming die 3. One end of the first through hole 12 is communicated with the first fixing groove 13, and the other end of the first through hole 12 is communicated with one end of the forming die 3 far from the fixture one 4. A threaded hole 11 is opened in the first fixing block 10. A screw rod can be inserted into the first through hole 12, and the screw rod is screwed into the threaded hole 11 in the first fixing block 10 to relatively fix the first fixing block 10 and the forming die 3.

[0034] As Figures 5-9 shown, the upsetting tooling includes a second mounting seat 16 and a second fixture 19. A upsetting die 17 and a necking die 18 are mounted on one side of the second mounting seat 16 close to the second fixture 19. A ring groove 28 is opened on one side of the upsetting die 17 close to the second fixture 19. A second forming groove 27 is opened on one side of the ring groove 28 far from the second fixture 19. The size of the second forming groove 27 is smaller than that of the ring groove 28. A support die 24 is arranged in the second forming groove 27. The support die 24 is arranged according to the shapes of the flat mouth section 34 and the transition section 35. The second fixture 19 includes two clamping blocks two 20. Mounting grooves two 21 are opened on the opposite sides of the two clamping blocks two 20. A support groove 23 is arranged at one end of the mounting groove two 21 close to the second mounting seat 16. A positioning groove two 22 is arranged on one side of the support groove 23 far from the second mounting seat 16.

[0035] The cooling pipe 32 is placed in the installation groove two 21 of one of the clamping blocks two 20. The positioning ring one 33 is located in the positioning groove two 22. The transition section 35 is located in the support groove 23, and the flat mouth section 34 is located outside the clamping block two 20. After the other clamping block two 20 is pressed on, the two clamping blocks two 20 are relatively fixed to clamp the cooling pipe 32. The pier head die 17 moves towards the fixture two 19, and the flat mouth section 34 enters the uniform gap between the forming groove two 27 and the support die 24. The inner end of the forming groove two 27 abuts against the end of the flat mouth section 34 and continues to move towards the flat mouth section 34 to extrude the end of the flat mouth section 34. The flat mouth section 34 is extruded and deformed towards the annular groove 28, so as to form a positioning ring two 31 on the outer periphery of the flat mouth section 34, as Figure 12 shown. The necking die 18 then moves towards the fixture two 19 to perform necking treatment on the flat mouth section 34.

[0036] A mandrel 29 is arranged on one side of the support die 24 close to the fixture two 19. The mandrel 29 can extend into the transition section 35 to support the pipe wall and prevent the transition section 35 from being extruded and deformed.

[0037] A fixing groove two 26 is arranged on one side of the forming groove two 27 away from the annular groove 28. A fixing block two 30 is connected to one side of the support die 24 away from the mandrel 29. The fixing block two 30 is arranged in the fixing groove two 26. A through hole two 25 is opened in the pier head die 17. The through hole two 25 is respectively communicated with the end of the pier head die 17 and the fixing groove two 26. A screw is inserted into the through hole two 25. A threaded hole is opened in the fixing block two 30. The end of the screw can be screwed into the threaded hole of the fixing block two 30, so as to fix the fixing block two 30 and the pier head die 17.
