Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] Depend on Figure 1-4 Provided is a feeding device for continuous stamping of a stamping die, comprising a stamping workbench 1,

[0025] A conveying assembly 2 is assembled on the stamping workbench 1, and a clamping assembly 3 is slidably assembled in the conveying assembly 2;

[0026] The conveying assembly 2 includes a double motor seat 21 disposed on the stamping workbench 1, two screw rods 23 are rotatably disposed in the double motor seat 21, the outer portions of the two screw rods 23 are meshed with sliding sleeves 24, the outer portions of the two sliding sleeves 24 are jointly sleeved with a slider seat 25, and a bearing seat 26 is supported on the slider seat 25;

[0027] The clamping assembly 3 includes four rectangular positioning blocks 31 mounted on the bearing seat 26 , a sliding groove is provided between two adjacent positioning blocks 31 and a squeezing block 34 is slidably provided thereon, and a rubber block 35 is integrally protruded from the side surface of each squeezing block 34 .

[0028] In this embodiment, by cooperating with the components within the clamping assembly 3, when the workpiece is placed between the four extrusion blocks 34, the compression spring 33 pushes the extrusion blocks 34, and the four extrusion blocks 34 can move in a cross shape until the workpiece is clamped. Compared with the direct pushing method in the cited document, the present application clamps the workpiece by adding a clamping assembly 3 in a radial movement manner, so that the restriction of smaller workpieces can be completed through the opposite movement of the four extrusion blocks 34, which is convenient for the stamping mechanism 4 to perform stamping operations on the workpiece, thereby ensuring that the smaller workpiece maintains a stable position and posture during the stamping process; the four rubber blocks 35 for elastic clamping can also be adjusted according to the shape and size of the workpiece to ensure that the clamping force is suitable for the requirements of the workpiece, avoid displacement or deformation of the workpiece during the stamping process, and improve the stamping consistency of the workpiece.

[0029] Specifically, refer to Figure 3-4 A side plate 32 is installed between two adjacent positioning blocks 31 , and the slide groove between the adjacent positioning blocks 31 of the side plate 32 is closed. A compression spring 33 is also hooked at one end of the side plate 32 , and the other end of the compression spring 33 is connected to the extrusion block 34 .

[0030] In this embodiment, in actual use, the provided compression spring 33 can push the extrusion block 34. When the stamped workpiece is placed between the four extrusion blocks 34, the extrusion block 34 can squeeze the compression spring 33 due to the size of the workpiece. When the workpiece is completely placed between the four extrusion blocks 34, the provided compression spring 33 can be reset, thereby driving the extrusion block 34 to move in a straight line until the rubber block 35 on the side of the extrusion block 34 clamps the workpiece. In the preferred setting, the specifications of the four compression springs 33 remain consistent. At the same time, in long-term use, in order to ensure that the elastic coefficient of the compression spring 33 is maintained, the user needs to regularly inspect and replace the compression spring 33 to ensure stable clamping of the workpiece.

[0031] Furthermore, the rubber block 35 can effectively protect the surface of the workpiece from scratches, damage or deformation; the rubber block 35 made of rubber material can provide a gentle clamping method, reduce friction and pressure on the surface of the workpiece, and ensure the quality and appearance of the workpiece during the stamping process.

[0032] Specifically, refer to Figure 3-4 The four positioning blocks 31 are all provided with threaded holes and are assembled with a sealing plate 36 through hexagon socket bolts. The sealing plate 36 is provided with a cross groove 37, and the tops of the four extrusion blocks 34 slide in the cross groove 37.

[0033] In this embodiment, the cross slide groove 37 is provided to allow the extrusion blocks 34 to slide normally during use, and the sealing plate 36 is provided to limit the four extrusion blocks 34 to prevent the extrusion blocks 34 from moving or tipping over.

[0034] Specifically, refer to Figure 3-4 The extrusion block 34 is arranged in an L shape and its top is higher than the positioning block 31 . The vertical size of the extrusion block 34 is compatible with the opening size of the cross slide 37 . The horizontal bottom size of the extrusion block 34 is larger than the cross slide 37 and is against the bottom of the sealing plate 36 .

[0035] In this embodiment, in actual use, when the stamping mechanism 4 is performing a stamping operation on the workpiece between the four extrusion blocks 34, in order to prevent the compression spring 33 and the extrusion block 34 from being offset and misaligned, in the preferred design, the size of the cross slot 37 is adapted to the vertical portion of the extrusion block 34, thereby ensuring the normal sliding of the extrusion block 34, and the size of the cross slot 37 is smaller than the bottom parallel portion of the extrusion block 34, so that the extrusion block 34 can always be in radial sliding in the cross slot 37, and at the same time, one end will not flip, and the workpiece is always clamped radially.

[0036] Specifically, refer to Figure 1-2 Two deep groove ball bearings are assembled in the double motor seat 21, and one end of the two screw rods 23 is rotatably matched with one of the deep groove ball bearings. The conveying assembly 2 also includes a positioning seat 22 arranged on the stamping workbench 1, and one end of the two screw rods 23 is rotated on the positioning seat 22. The bearing seat 26 is detachably assembled on the slider seat 25 by bolts.

[0037] In this embodiment, during use, two groups of motors are assembled in the dual motor seat 21, and the output ends of the motors are respectively connected to one of the screw rods 23 for rotation. When the user connects the power supply to the two groups of motors in the dual motor seat 21, the two screw rods 23 can be driven to rotate synchronously through the two groups of motor output ends. The bearing parts arranged in the dual motor seat 21 can further ensure the rotation stability of the motor output ends and the screw rods 23, and ensure that the screw rods 23 will not vibrate when rotating, thereby stably providing radial displacement power to the sliding sleeve 24.

[0038] Specifically, refer to Figure 1-2 A stamping mechanism 4 is mounted on the stamping workbench 1 . The stamping mechanism 4 is disposed on one side of the conveying component 2 and horizontally disposed vertically above the clamping component 3 .

[0039] In this embodiment, in actual use, the mutual movement and coordination of the multiple components within the conveying assembly 2 can drive the clamping assembly 3 to slide radially along the plane of the stamping workbench 1. The user can drive the clamping assembly 3 to move to the bottom of the stamping mechanism 4, and then use the stamping mechanism 4 to complete the stamping operation of the workpiece on the clamping assembly 3.

[0040] The feeding device for continuous stamping of the stamping die of the utility model:

[0041] Step 1: In actual use, when the user performs stamping processing on a small workpiece, the workpiece to be stamped is placed between the four rubber blocks 35, and the rubber blocks 35 are used to fit and clamp the workpiece. When the workpiece is placed between the four extrusion blocks 34, the compression spring 33 pushes the extrusion block 34, so that the compression spring 33 can push the extrusion block 34 and the rubber block 35 to move radially until the four extrusion blocks 34 clamp the workpiece in a cross shape. At this time, the workpiece can be restricted by the opposite movement of the four extrusion blocks 34, which is convenient for the stamping mechanism 4 to perform stamping operations on the workpiece;

[0042] Step 2: When the user connects the power supply to the two sets of motors in the dual motor seat 21, the two sets of motor output ends can drive the two screw rods 23 to rotate synchronously. At this time, the two sliding sleeves 24 engaged on the outside of the screw rod 23 can move in a straight line within the stroke range of the screw rod 23 due to the limitation of the slider seat 25, thereby driving the slider seat 25 and the bearing seat 26 to move in a straight line. At this time, the bearing seat 26 set can drive the clamping assembly 3 to move to the bottom of the stamping mechanism 4, so that the stamping mechanism 4 performs the stamping operation on the workpiece on the clamping assembly 3.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
