[0048] See also Figures 1 to 6 This embodiment provides a stamping workpiece transfer mechanism, including a base 10, a material transfer cylinder 20, a grid 30, a gas delivery device and a driving mechanism 40.

[0049] The transfer barrel 20 is rotatably arranged on the base 10, one end of the transfer barrel 20 is an air inlet 21, and the other end of the transfer barrel 20 is an air outlet 22. The transfer barrel 20 can be rotated and switched between vertical and horizontal states. The grille 30 is arranged in the transfer barrel 20 to block the workpiece from entering the transfer barrel 20 from the air outlet 22 when the transfer barrel 20 is in the vertical state.

[0050] Specifically, the vertical and horizontal states of the material transfer barrel 20 refer to: the vertical state is a state in which the axis of the material transfer barrel 20 is perpendicular to the horizontal plane, the air outlet 22 of the material transfer barrel 20 is located directly below the lower end of the blanking hole of the continuous stamping die, and the workpiece in the blanking hole can fall into the material transfer barrel 20 from the air outlet and be blocked by the grille 30; the horizontal state is a state in which the axis of the material transfer barrel 20 is parallel to the horizontal plane.

[0051] The gas delivery device (not shown) is used to input gas into the air inlet 21 to push the workpiece in the transfer barrel 20 to move. The driving mechanism 40 is used to drive the transfer barrel 20 to rotate. Specifically, the gas delivery device adopts the existing technology, and can input air with higher kinetic energy from the air inlet 21 of the transfer barrel 20 into the transfer barrel 20 to push the workpiece in the transfer barrel 20.

[0052] In this embodiment, the material transfer barrel 20 is driven to rotate by the driving mechanism 40, so that the material transfer barrel 20 is in a vertical state and a horizontal state. When the material transfer barrel 20 is in a vertical state, the workpiece at the blanking hole on the lower die of the continuous stamping die falls into the material transfer barrel 20 from the air outlet 22 of the material transfer barrel 20 and is blocked by the grille 30, and then the driving mechanism 40 drives the material transfer barrel 20 to rotate to a horizontal state, and the gas conveying device conveys gas from the air inlet 21 to the material transfer barrel 20 to push the workpiece in the material transfer barrel 20 to move and then be ejected from the air outlet 22. A material frame is placed on one side of the machine, and the ejected workpiece is transferred from the bottom of the continuous stamping die to the material frame. There is no need for workers to always pay attention to the accumulation of workpieces, nor is there any need to manually transfer the workpieces, which is more convenient.

[0053] In one embodiment, the stamping workpiece transfer mechanism further includes an air inlet cylinder 50 and a discharge cylinder 51 .

[0054] The inlet cylinder 50 and the outlet cylinder 51 are both arranged on the base 10. The gas delivery device is connected to one end of the inlet cylinder 50; when the transfer cylinder 20 is in a horizontal state, the end of the inlet cylinder 50 away from the gas delivery device is connected to the inlet port 21, and the outlet cylinder 51 is connected to the outlet port 22.

[0055] In this embodiment, the gas delivery device delivers gas to the horizontal transfer cylinder 20 through the gas inlet cylinder 50, pushing the workpiece in the transfer cylinder 20 to be ejected from the discharge cylinder 51. The discharge cylinder 51 can maintain the gas kinetic energy output by the gas delivery device, so that the workpiece can be moved farther when being pushed.

[0056] In one embodiment, a support rod 23 is connected to the middle of the transfer barrel 20 and arranged along its radial direction. The support rod 23 is rotatably connected to the base 10. The air inlet barrel 50 and the discharge barrel 51 are arc-shaped and concave toward one end of the transfer barrel 20. The two ends of the transfer barrel 20 are arc-shaped and convex, and respectively fit with the corresponding ends of the air inlet barrel 50 and the discharge barrel 51. In addition, the air inlet barrel 50 and the discharge barrel 51 are arranged horizontally, that is, the axes of the two are parallel to the horizontal plane.

[0057] In this embodiment, the transfer barrel 20 rotates around the axis of the support rod 23. In the process of the transfer barrel 20 changing from a vertical state to a horizontal state, the two ends of the transfer barrel 20 gradually align with the ends of the air inlet barrel 50 and the ends of the discharge barrel 51 on both sides. Since the ends of the air inlet barrel 50 and the discharge barrel 51 are arc-shaped and concave, and the two ends of the transfer barrel 20 are arc-shaped and convex, the transfer barrel 20 can maintain a close distance with the two after being aligned, so that the gas in the air inlet barrel 50 loses as little kinetic energy as possible in the process of pushing the workpiece, so that the workpiece can be stably pushed out of the machine and fall into the material basket on the outside.

[0058] In one embodiment, the stamping workpiece transfer mechanism further includes a first leakproof sleeve 60 and a second leakproof sleeve 61, which are respectively slidably sleeved on both ends of the material transfer barrel 20, and the first leakproof sleeve 60 can partially slide onto the end of the air inlet barrel 50, and the second leakproof sleeve 61 can partially slide onto the end of the material discharge barrel 51, and the driving mechanism 40 can drive the first leakproof sleeve 60 and the second leakproof sleeve 61 to slide on the material transfer barrel 20. Specifically, the inner wall of the first leakproof sleeve 60 and the second leakproof sleeve 61 can be partially or entirely made of rubber material. In addition, the inner wall of the first leakproof sleeve 60 and the second leakproof sleeve 61 is provided with an axial groove, and the outer wall of the material transfer barrel 20 is provided with a protrusion, and the groove and the protrusion are slidably matched along the axial direction of the material transfer barrel 20, so that the first leakproof sleeve 60 and the second leakproof sleeve 61 can slide on the material transfer barrel 20.

[0059] In this embodiment, when the material transfer barrel 20 is in a horizontal state, the first leakproof sleeve 60 and the second leakproof sleeve 61 are driven by the driving mechanism 40 to slide on the material transfer barrel 20 to the corresponding air inlet barrel 50 and the discharge barrel 51, so as to cover the gap between the air inlet barrel 50 and the material transfer barrel 20 and the gap between the discharge barrel 51 and the material transfer barrel 20 to a certain extent, reduce the amount of gas leakage there, and thus minimize the thrust loss of gas on the workpiece caused by gas leakage. The rubber on the inner wall of the first leakproof sleeve 60 and the second leakproof sleeve 61 can further enhance this effect.

[0060] In one embodiment, the driving mechanism 40 includes a first bar-shaped trigger block 41 , a second bar-shaped trigger block 42 , a driving gear 43 and a motor 44 .

[0061] The first strip-shaped trigger block 41 is arranged along the axis of the material transfer barrel 20, one end of the first strip-shaped trigger block 41 is connected to a side of the first leak-proof sleeve 60 facing the second leak-proof sleeve 61, and the other end of the first strip-shaped trigger block 41 can abut against the second leak-proof sleeve 61. The second strip-shaped trigger block 42 is arranged along the axis of the material transfer barrel 20, one end of the second strip-shaped trigger block 42 is connected to a side of the second leak-proof sleeve 61 facing the first leak-proof sleeve, and the other end of the second strip-shaped trigger block 42 can abut against the first leak-proof sleeve 60.

[0062] The driving gear 43 is arranged between the first bar-shaped trigger block 41 and the second trigger block. The motor 44 is arranged on the base 10, and the output end of the motor 44 is coaxially connected with the driving gear 43; the first bar-shaped trigger block 41 and the second bar-shaped trigger block 42 are respectively meshed with the driving gear 43 by setting racks. The driving gear 43 is coaxial with the support rod 23.

[0063] In this embodiment, the motor 44 drives the driving gear 43 to rotate, thereby driving the first bar-shaped trigger block 41 and the second bar-shaped trigger block 42 to move, so that the first leak-proof sleeve 60 and the second leak-proof sleeve 61 can slide on the material transfer barrel 20 .

[0064] In one embodiment, a first guide protrusion 62 is connected to an outer wall of the first leak-proof sleeve 60 on a side facing away from the motor 44, and a second guide protrusion 63 is connected to an outer wall of the second leak-proof sleeve 61 on a side facing away from the motor 44;

[0065] The driving mechanism 40 further includes a guide plate 45 disposed on the base 10; the guide plate 45 is provided with two centrally symmetrical guide grooves 46. Specifically, the two guide grooves 46 are centrally symmetrical with the axis of the support rod 23 as the center. The first guide protrusion 62 and the second guide protrusion 63 can be inserted into the corresponding guide grooves 46 and slide along the guide grooves 46. The end surface of the guide plate 45 is perpendicular to the axis of the support rod 23.

[0066] The guide groove 46 includes an arc segment 461 and a horizontal segment 462 .

[0067] The arc segment 461 is opened along the circumferential direction of the support rod 23. The horizontal segment 462 is connected to one end of the arc segment 461, and the horizontal segment 462 is opened along the radial direction of the support rod 23.

[0068] In this embodiment, when the transfer barrel 20 is in a horizontal state, the first guide protrusion 62 and the second guide protrusion 63 are in the horizontal section 462 of the guide groove 46. Figure 1 At this time, the driving gear 43 rotates clockwise, and the first strip trigger block 41 and the second strip trigger block 42 respectively drive the first leak-proof sleeve 60 and the second leak-proof sleeve 61 to move outward, thereby covering the gaps between the material transfer barrel 20 and the air inlet barrel 50, and between the material transfer barrel 20 and the material discharge barrel 51, thereby achieving a certain effect of preventing gas leakage, and the first guide protrusion 62 and the second guide protrusion 63 both slide in the horizontal section 462.

[0069] When the driving gear 43 rotates counterclockwise, the first strip trigger block 41 and the second strip trigger block 42 respectively drive the first leak-proof sleeve 60 and the second leak-proof sleeve 61 to move inward, until the end of the first strip trigger block 41 away from the first leak-proof sleeve 60 abuts against the second leak-proof sleeve 61, and the end of the second strip trigger block 42 away from the second leak-proof sleeve 61 abuts against the first leak-proof sleeve 60, at which time the first guide protrusion 62 and the second guide protrusion 63 slide to the position of the arc segment 461.

[0070] As the driving gear 43 further rotates counterclockwise, the first strip trigger block 41 and the second strip trigger block 42 cannot move further, and the entire transfer barrel 20 connected to the first leak-proof sleeve 60 and the second leak-proof sleeve 61 rotate counterclockwise. At this time, the first guide protrusion 62 and the second guide protrusion 63 slide in the arc segment 461 until the transfer barrel 20 is in a vertical state. The transfer barrel 20 can receive the workpiece dropped from the blanking hole of the lower die of the upper continuous stamping die. The rotation of the transfer barrel 20 can be realized by the driving gear 43, and the gap between the transfer barrel 20 and the air inlet barrel 50, and the gap between the transfer barrel 20 and the discharge barrel 51 can also be leak-proof.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
