Description

Technical Field

[0001] The present application relates to the technical field of forging dies, and in particular to a discharge device. Background Art

[0002] Back-extrusion forgings often tend to cling to the upper die and be carried out of the die along with it. This typically requires a discharge device to facilitate the separation of the forging from the die. Conventional discharge devices are typically located on the upper or lower die and typically utilize a spring-loaded structure. This results in a longer punch die design, shortening its service life and increasing replacement costs. To address this issue, the inventors have proposed a discharge device. Utility Model Content

[0028] In order to make the purpose, technical solutions and advantages of this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0029] Example 1

[0030] In the related art, reverse extrusion forgings are usually easy to hold the upper die tightly and be carried out of the die along with the upper die. Generally, a unloading device needs to be provided to facilitate the separation of the forgings from the die. Conventional unloading devices are usually provided on the upper die or the lower die, and they are usually a structure with a spring, which results in the punch die needing to be designed longer, resulting in a short service life of the punch die and high replacement cost.

[0031] This embodiment provides a discharge device, which can reduce space occupation, facilitate the short design of the punch die, and help to increase the service life of the punch die and reduce costs.

[0032] See also Figure 1-Figure 2 In this embodiment, a unloading device includes a plate 10, and the plate 10 has a discharge hole 11 and a positioning hole 12. The discharge hole 11 corresponds to the mold cavity of the lower mold 30. The discharge hole 11 allows the forging 50 to pass through. The positioning hole 12 is penetrated by a bolt 20 connected to the lower mold 30. The plate 10 can move relative to the bolt 10 to press the forging 50 into the mold cavity.

[0033] By adopting the technical solution of this embodiment, the forging 50 is pressed into the die cavity of the lower die 30 by moving the plate 10 relative to the bolt 20, which can prevent the forging 50 from being carried out of the die cavity by the punch die 40. The plate 10 can reduce the space occupied along the axial direction of the die cavity, facilitate the short design of the punch die 40, and help to increase the service life of the punch die 40 and reduce costs.

[0034] In this embodiment, the plate 10 is constructed into a longitudinal plate shape, and the plate 10 has a certain thickness. The positioning hole 11 is a circular through hole formed in the middle position of the plate 10. The positioning hole 11 is arranged corresponding to the mold cavity of the lower mold 30, and is used to allow the forging 50 to be placed into the mold cavity through the positioning hole 11.

[0035] In addition, two positioning holes 12 are provided on the plate 10, and the positioning holes 12 are constructed as long straight holes. The positioning holes 12 are arranged along the radial direction of the discharge hole 11, and the two positioning holes 12 are symmetrically arranged on both sides of the discharge hole 11. The two positioning holes 12 are arranged parallel to each other. A bolt 20 is passed through the inside of each positioning hole 12, and the bolt 20 is screwed on the top surface of the lower mold 30. The two bolts 20 fix the plate 10 to the top surface of the lower mold 30, and after loosening the bolts 20, the plate 10 can be moved as a whole along the extension direction of the positioning holes 12, thereby covering part of the top surface of the forging 50, so as to press the forging 50 into the mold cavity of the lower mold 30.

[0036] It should be noted that when the positioning hole 12 is coaxial with the mold cavity, the bolt 20 is located at the rightmost end of the positioning hole 12. In order to increase the crimping area of ​​the plate 10 on the forging 50, a longitudinal slide 13 is provided on the left outer edge of the discharge hole 11, and the extension direction of the slide 13 is on the same straight line as the extension direction of the positioning hole 12. The width of the slide 13 is smaller than the diameter of the forging 50, and the width of the slide 13 is slightly larger than the outer diameter of the punch of the punch die 40. When the plate 10 moves to the right as a whole until the bolt 20 is located at the left end of the positioning hole 12, the aforementioned punch is located inside the slide 13, and the forging 50 is crimped under the slide 13.

[0037] It should be understood that this embodiment restricts the forging 50 inside the die cavity of the lower die 30 by the movement of the plate 10 relative to the bolt 20, and can form a blocking effect on the forging 50 at the top of the die cavity to prevent the forging 50 from being carried out of the die cavity by the punch die 40; and the plate 10 can achieve a lightweight design while ensuring structural strength, thereby reducing the space occupied between the lower die 30 and the punch die 40, facilitating the realization of a short design of the punch die 40, and helping to increase the service life of the punch die 40 and reduce costs.

[0038] Example 2

[0039] See also Figure 3-Figure 4 The difference between this embodiment and embodiment 1 is that the configuration of the positioning hole is different.

[0040] In this embodiment, the positioning hole 12 is constructed as a circular hole as a whole, and the axis of the positioning hole 12 is parallel to the axis of the mold cavity. The bolt 20 is passed through the inside of the positioning hole 13, and the plate 10 as a whole can rotate around the bolt 20, so that the discharge hole 11 is misaligned with the mold cavity, thereby crimping the forging 50 inside the mold cavity.

[0041] In order to improve the stability of the plate 10 after it is fixed, an arc groove 14 coaxially arranged with the positioning hole 12 can be further provided on the plate 10, and the arc groove 14 and the positioning hole 12 are respectively placed on both sides of the discharge hole 11, and a bolt 20 is also passed through the inside of the arc groove 14. When the discharge hole 11 is coaxial with the mold cavity, the bolt 20 is located at the lower end of the arc groove 14. After the forging 50 is placed into the mold cavity through the discharge hole 11, the plate 10 is rotated counterclockwise so that the bolt 20 moves relatively to the top of the arc groove 14. At this time, the discharge hole 11 and the mold cavity are misaligned, and the forging 50 is pressed into the mold cavity by the plate 10.

[0042] Example 3

[0043] See also Figure 5The difference between this embodiment and embodiment 1 is that a rectangular mounting groove 15 is opened on the side of the plate 10, and avoidance holes 16 penetrating the plate 10 are provided on the upper and lower sides of the mounting groove 15. A module 17 is inserted into the mounting groove 15. The module 17 is constructed as a rectangular plate that is adapted to the shape of the mounting groove 15. The discharge hole 11 and the slide groove 13 are arranged on the module 17. The avoidance hole 16 is also constructed in a rectangular shape. The discharge hole 11 and the slide groove 13 are located as a whole in the space formed by the avoidance hole 16. By replacing different modules 17 (different modules refer to different apertures of the discharge hole 11 and widths of the slide groove 13), the applicability of the unloading device can be improved.

[0044] In this embodiment, the punch die 40 will bring the forging 50 upwards to contact the die block 17 when being pushed out, and then the punch die 40 is separated from the forging 50 under the obstruction of the die block 17 .

[0045] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
