Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 The present invention provides the following technical solution: a device for realizing the simultaneous completion of tube forming and punching, comprising a base 21 and a cover plate 22 installed above the base 21, a first tube positioning block 1 installed on the top of the base 21, a first driving knife block 2 installed on the top of the base 21 and behind the first tube positioning block 1, a double-acting driving knife 3 installed on both sides of the top of the base 21 and on both sides of the first driving knife block 2, two symmetrically distributed horizontal sliders 4 slidably installed on the top of the base 21, two symmetrically distributed second tube positioning blocks 5 installed on the top of the base 21, two symmetrically distributed forming-punching stripping blocks 6 installed on the top of the base 21, and two symmetrically distributed forming-punching mandrels 7 installed on the top of the base 21.

[0020] The first tube positioning block 1 and the second tube positioning block 5 are used to position the tube in the mechanism. The first drive knife block 2 is used to counteract the lateral force of the double-action drive knife 3. The double-action drive knife 3 drives the horizontal slider 4 and the forming-punching stripper block 6 to move. The forming-punching mandrel 7 is formed and punched inside the tube.

[0021] In this embodiment, a tube support block 8 is provided below each of the two forming-punching mandrels 7, a tube support block 8 is installed on both sides of the top of the base 21, a sliding forming block 9 is installed on both sides of the top of the base 21, and a single-action drive knife 10 is installed on both sides of the top of the base 21.

[0022] Among them, the single-action drive knife 10 drives the sliding forming block 9 to move forward and form.

[0023] In this embodiment, a second drive knife block 11 is installed on both sides of the top of the base 21, a tube pressure block 12 is provided above the forming-punching mandrel 7, and a mandrel guide block 13 is installed on both sides of the top of the base 21.

[0024] The second drive knife block 11 counteracts the lateral force of the single-action drive knife 10, and the mandrel guide block 13 ensures that the forming-punching mandrel 7 moves along the required path.

[0025] The upper pressure block 12 and the lower pipe support block 8 are used to position the pipe vertically.

[0026] In this embodiment, a mandrel connector 14 is installed behind the mandrel guide block 13, and a cylinder 16 is installed behind the base 21 via a support. The end of the cylinder 16 is connected to the rear of the mandrel connector 14.

[0027] The mandrel connector 14 is used to connect the forming-punching mandrel 7 and the cylinder 16. The cylinder 16 is used to drive the forming-punching mandrel 7 to move back and forth.

[0028] In this embodiment, a mandrel travel stop 15 is provided above the support. The mandrel travel stop 15 is used to limit the retraction stroke of the forming-punching mandrel 7.

[0029] In this embodiment, a punching drive block 17 is installed inside the horizontal slider 4. A punching punch 20 is installed on one side of the punching drive block 17 via a punch fixing plate 18. A return polyurethane block 19 is installed on one side of the punch fixing plate 18.

[0030] Among them, the double-acting drive knife 3 and the single-acting drive knife 10 are in contact with the punching drive block 17 and the sliding forming block 9, respectively. The forming-punching mandrel 7, mandrel guide block 13, mandrel connector 14, mandrel connector 15 and cylinder 16 are connected to form a sliding motion assembly.

[0031] In actual operation, when the tube is placed into the mechanism, the first tube positioning block 1, the second tube positioning block 5, and the lower tube support block 8 position the tube in the X / Y direction. The upper tube pressure block 12 moves downward to press the tube, achieving Z-direction positioning. Next, the forming-punching mandrel 7 is propelled into the inner hole of the tube by a cylinder to support the subsequent tube forming and punching. The double-action drive knife 3 and the single-action drive knife 10 continue to move downward in the first stage, pushing the horizontal slider 4, the forming-punching stripper block 6, and the sliding forming block 9 inward to form the tube. The double-action drive knife 3 and the single-action drive knife 10 continue to move downward in the second stage. At this time, the second inclined surface of the double-action drive knife 3 drives the punching drive block 17, the punch fixing plate 18, and the punching punch 20 forward to achieve punching. In the second stage, although the double-action drive knife 3 and the single-action drive knife 10 move downward again, the horizontal slider 4, the forming-punching stripper block 6, and the sliding forming block 9 no longer move. After punching is completed, the double-action drive knife 3 and the single-action drive knife 10 move upward. First, the punching drive block 17, the punch fixing plate 18, and the punching punch 20 retract under the elastic force of the return polyurethane block 19. Then, the other forming mechanisms retract in sequence, completing the forming of the entire tube and the punched workpiece.
