[0030] Through the following detailed description of the exemplary embodiments of the present utility model with reference to the accompanying drawings, other features and advantages of the present utility model will become clear. Description of the Drawings

[0031] The drawings incorporated in and forming a part of this specification illustrate embodiments of the present invention and, together with the description thereof, serve to explain the principles of the present invention.

[0032] Figure 1 It is a schematic structural diagram of a head drawing tool provided for the present invention. Detailed implementation manners

[0033] Now, various exemplary embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention.

[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation on the present invention, its application, or its use.

[0035] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0036] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0037] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0038] An embodiment of the present invention provides a head drawing tool. Referring to Figure 1 As shown, an embodiment of the present invention provides a head drawing tool, including: a female die 1, a male die 2, a female die base 3, a die ejector ring 4, and a pull rod 5 with coincident rotation centers.

[0039] It should be noted that the workpiece 6 before processing and the product after processing are generally circular, so the female die 1, the male die, and the die ejector ring 4 of the drawing tool are also circular. Of course, the workpiece 6 can also be polygonal, and correspondingly, the female die 1, the male die, and the die ejector ring 4 are also polygonal. Whether it is circular or polygonal, the rotation centers or geometric centers of the female die 1, the male die 2, the female die base 3, the die ejector ring 4, and the pull rod 5 coincide on the same vertical line to ensure the uniformity of the applied force during processing.

[0040] The female die 1 is disposed on the female die base 3, and the die ejector ring is disposed on the top of the female die 1;

[0041] The workpiece 6 is placed inside the female die 1;

[0042] The punch 2 is arranged on the top of the workpiece 6;

[0043] The punch 2 is provided with a through hole, and the pull rod 5 passes through the through hole and passes through the workpiece 6, the die 1 and the die base 3;

[0044] The outer wall of the punch 2 is in contact with the inner walls of the die 1 and the die ejecting ring 4.

[0045] It can be understood that the die 1 is placed on the die base 3, and then the workpiece 6 is placed in the die 1. It should be noted that the diameter of the bottom of the die 1 is not less than the outer diameter of the workpiece 6. Generally speaking, the outer wall of the workpiece 6 is in contact with the inner wall of the lower part of the die 1. The inner diameter of the workpiece 6 is larger than the inner diameter of the die base 3 to achieve the downward limiting and constraining effect on the workpiece 6. The die 1 is connected to the die base 3 by welding or fixing pins for lateral constraint to ensure that the die 1 and the die base 3 are always concentric. The punch 2 is arranged on the top of the workpiece 6, and moreover, the diameter of the bottom of the punch 2 is not greater than the inner diameter of the workpiece 6. Therefore, when the pull rod 5 passes through the through hole of the punch 2 and passes through the workpiece 6, the die 1 and the die base 3, the head of the pull rod 5 is clamped by the hoop 9 so that it is stuck in the second hole diameter of the punch 2. When the pull rod 5 is pulled downward, the pull rod 5 drives the punch 2 to press downward, and the workpiece 6 is pressed into the space between the die 1 and the punch 2. When the top of the workpiece 6 is in contact with the die ejecting ring 4, the pulling is stopped, and the pull rod 5 is lifted, and the punch 2 is hoisted to take out the processed workpiece 6.

[0046] It should be noted that the outer wall of the punch 2 is in contact with the inner walls of the die 1 and the die ejecting ring 4, and the gap between the punch 2 and the die 1 is not less than the wall thickness of the workpiece 6. In this way, the die 1 can shape the workpiece 6 into the required shape under the drive of the pull rod 5. Generally speaking, the method of mutual extrusion between the die 1 and the punch 2 is more easily used in the processing of the necked head. The shape of the head, that is, the shapes of the die 1 and the punch 2, can be set according to the actual application scenario.

[0047] Furthermore, both the die 1 and the punch 2 are provided with lifting lug screws 7;

[0048] The lifting lug screw 7 of the die 1 is arranged on the outer wall of the die 1;

[0049] The lifting lug screw 7 of the punch 2 is arranged on the top of the punch 2.

[0050] It can be understood that the die 1 needs to be hoisted and installed on the die base 3. Therefore, setting the lifting lug screw 7 on the outer wall of the die 1 is beneficial to the installation of the die 1. And when shaping the workpiece 6, it is also necessary to hoist the punch 2 onto the workpiece 6 first and then remove it after the workpiece 6 is shaped. Therefore, it is also necessary to set the lifting lug screw 7 to facilitate the movement of the punch 2.

[0051] Furthermore, the head drawing tooling further includes a fixing pin 8;

[0052] The fixing pin 8 is arranged between the female die 1 and the die ejecting ring 4.

[0053] Before the workpiece 6 is shaped, after the female die 1 is installed on the female die base 3, the die ejecting ring 4 is installed on the top of the female die 1 and connected by the fixing pin 8. After the workpiece 8 is extruded to be flush with the top of the die ejecting ring 4, the downward drawing is stopped. Therefore, the shape of the inner wall of the die ejecting ring 4 needs to be adapted to the shape of the workpiece 6 to be shaped together with the female die 1. Secondly, after the punch 2 is removed, the workpiece 6 still fits tightly with the female die 1 and the die ejecting ring 4 and is not easy to remove. At this time, first remove the fixing pin 8 and then remove the die ejecting ring 4. At this time, the edge of the workpiece 6 is exposed, which is convenient for removing the workpiece 6 from the female die 1.

[0054] Furthermore, the through hole of the punch 2 includes a first diameter hole and a second diameter hole located at the top of the first diameter hole; the aperture of the second diameter hole is larger than that of the first diameter hole.

[0055] The head drawing tooling further includes a hoop 9;

[0056] The hoop 9 is arranged in the second diameter hole;

[0057] The diameter of the pull rod 5 is adapted to the aperture of the first diameter hole;

[0058] The outer diameter of the hoop 9 is adapted to the aperture of the second diameter hole, and the inner diameter of the hoop 9 is adapted to the diameter of the pull rod 5. The pull rod 5 includes a straight rod and a rod head arranged at the end of the straight rod;

[0059] The diameter of the bottom of the rod head 5 is larger than the inner diameter of the hoop 9.

[0060] It can be understood that the through hole of the punch 2 for the pull rod 5 to pass through includes two sections, the first diameter hole located below and the second diameter hole located above. The apertures of the first diameter hole and the second diameter hole are different, and the aperture of the second diameter hole is larger than that of the first diameter hole. The female die 1, the female die base 3 and the pull rod 5 are relatively fixedly arranged. Therefore, after the workpiece 6 is placed in the female die 1, it is necessary to hoist the punch 2 through the pull rod 5 and place it on the workpiece 6. The diameter of the pull rod 5 is adapted to the aperture of the first diameter hole. Specifically, the aperture of the first diameter hole is slightly larger than the diameter of the pull rod 5 (the diameter of the pull rod 5 here refers to the diameter of the thickest position of the pull rod 5). Also, since the aperture of the second diameter hole is larger than that of the first diameter hole, it can be ensured that the pull rod 5 can pass through the punch 2 smoothly.

[0061] In addition, the pull rod 5 acts on the punch 2 to pull it to extrude the workpiece 6, so the pull rod 5 must be in contact with the punch 2. However, the diameter of the through hole for the pull rod 5 to pass through is larger than the diameter of the pull rod 5. Therefore, a ferrule 9 is provided between the pull rod 5 and the punch 2. The ferrule 9 can be two semi-circular rings, and the diameter of the second diameter hole of the outer diameter of the ferrule 9 is adapted. Preferably, the ferrule 9 just fits into the second diameter hole, and the inner diameter of the ferrule 9 is adapted to the diameter of the pull rod 5 (the diameter of the pull rod 5 here refers to the diameter of the thinnest position of the pull rod 5, which is also the diameter of the straight rod). The pull rod 5 also includes a thin straight rod and a thick rod head, and the diameter of the bottom of the rod head 5 is larger than the inner diameter of the ferrule 9. In this way, after the punch 2 is hoisted through the pull rod 5, the ferrule 9 is snapped between the pull rod 5 and the punch 2. The pull rod 5 can apply a force to the punch 2 through the ferrule 9, and then the punch 2 is extruded downward to shape the workpiece 6.

[0062] The head drawing tooling further includes a hydraulic mechanism, and the hydraulic mechanism is connected to the pull rod 5. The hydraulic mechanism can be connected to the bottom of the pull rod 5 to pull the pull rod 5 downward, and then drive the punch 2 to shape the workpiece 6. The hydraulic mechanism can also be connected to the top of the pull rod 5 to press the pull rod 5 downward, and can also drive the punch 2 to shape the workpiece 6.

[0063] In summary, the head drawing tooling provided by the present utility model at least achieves the following beneficial effects:

[0064] In the embodiment provided by the present utility model, through the female die and the male die with the inner and outer shapes fitting each other, and the pull rod capable of driving the male die to move, after the workpiece is placed on the female die, the pull rod drives the male die to extrude the workpiece, so that it is shaped into a shape fitting the female die and the male die. And by setting the die withdrawal ring, it is convenient for the workpiece to be demolded. The head drawing workpiece structure provided by the present utility model is simple, can process standard workpieces (such as cylinders) into the required shapes according to actual application scenarios, has a wide application range and high economy.
