Description

Technical Field

[0001] The utility model relates to the technical field of fastener forming dies, and more specifically to a fastener hot upsetting anti-deformation forming die. Background Art

[0002] The fastener hot upsetting anti-deformation forming die is a forming die used to manufacture fasteners. Fasteners include bolts, nuts, screws, etc., which are used to connect and fix parts of mechanical equipment. Since fasteners usually need to have a certain strength and durability, hot upsetting is required to increase the strength of fasteners during the manufacturing process. Hot upsetting is a process in which a metal bar is heated to a certain temperature and then pressure is applied in a die to deform it.

[0003] Among them, after searching, it was found that the patent application number CN202022037484.0 discloses a fastener forming mold, which involves the field related to fastener production, and is to solve the problem in the prior art that multiple fasteners of different specifications cannot be produced synchronously. A connecting card slot is arranged inside the mold shell, and the mold shell is arranged in a circular ring shape. There are multiple connecting card slots, and the diameters of the multiple connecting card slots gradually decrease from top to bottom. A forming mold is arranged inside the connecting card slot, and the number of forming molds is set to be consistent with the number of connecting card slots;

[0004] When this structure is in use, during the process of the fastener forming mold, the user can quickly install and replace the entire column through the threaded installation groove and the installation column, thereby reducing the user's required use cost of the entire fastener forming mold. However, when the fastener is formed, it is not easy to perform hot upsetting on it, causing the fastener to cool quickly, thereby causing the fastener to deform. Utility Model Content

[0009] It can be seen that in the above technical solution, the forming die body is displaced downward and stuck in the forming cavity, and the material is squeezed by the pressure of the displacement of the forming die body to form it. At the same time, the forming die body is heated by the heating wire, so that the material is deformed by heat in the forming cavity. Combined with the pressure of the displacement of the forming die body and the limitation of the forming cavity, the material can be effectively prevented from being deformed during hot upsetting, thereby improving the material molding quality.

[0010] Optionally, in a possible implementation, a gasket is provided on the top of the shaping mold, a molding cavity matching the molding die body is opened on the gasket, a gasket for support is provided on the top of the pressing block and the bottom of the shaping mold, and each of the gaskets is detachably connected to the pressing plate and the supporting plate, respectively, a hydraulic rod for driving is provided on the top and bottom of the support frame, and the output end of each of the hydraulic rods extends to the pressing plate and the supporting plate respectively and is detachably connected to the pressing plate and the supporting plate, the pressing plate and the supporting plate are both slidably connected to the support frame, and the pressing block and the shaping mold are both on the same axis;

[0011] It can be seen that in the above technical solution, the material is in the molding cavity, and the hydraulic rod on the top of the pressure plate is used to drive the pressure plate downward, and the pressure block and the molding die body are moved downward. Through the setting of the limit sleeve and the limit plate, the molding die body can be supported to prevent the molding die body from being deformed due to pressure and affecting the molding quality of the material in the molding cavity.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] As attached Figure 1-4 The fastener hot upsetting anti-deformation forming die shown in the figure can move the forming die body 8 downward and be stuck in the forming cavity 12 through the hot upsetting pressurizing assembly set on the support frame 1, and the material is squeezed by the pressure when the forming die body 8 is displaced to form it. At the same time, the forming die body 8 is heated by the heating wire 10, so that the material is deformed by heat in the forming cavity 12. Combined with the pressure of the displacement of the forming die body 8, the material is limited by the forming cavity 12, which can effectively prevent the material from being deformed during hot upsetting, and improve the material molding quality. The specific structure of the assembly is set as follows;

[0023] The hot upsetting and pressurizing assembly includes a pressing plate 2 arranged at the top of the inner cavity of the support frame 1, a supporting plate 3 located at the bottom of the inner cavity of the support frame 1 is arranged at the bottom of the pressing plate 2, a pressing block 4 is arranged at the bottom of the pressing plate 2, and a shaping die 5 is arranged at the top of the supporting plate 3;

[0024] A molding die body 8 for pressurizing is arranged at the bottom of the pressing block 4, a center column 6 located in the middle of the pressing block 4 is arranged inside the molding die body 8, a limiting sleeve 7 is arranged at the bottom of the center column 6, a limiting plate 9 is arranged in the middle of the limiting sleeve 7, and a heating wire 10 for heating is arranged on the outside of the limiting plate 9 and at the bottom of the limiting sleeve 7.

[0025] A gasket 11 is provided on the top of the shaping mold 5, and a molding cavity 12 matching the molding die body 8 is opened on the gasket 11. The top of the pressing block 4 and the bottom of the shaping mold 5 are both provided with gaskets 11 for support, and each gasket 11 is detachably connected to the pressing plate 2 and the support plate 3 respectively. A hydraulic rod 14 for driving is provided on the top and bottom of the support frame 1, and the output end of each hydraulic rod 14 extends to the pressing plate 2 and the support plate 3 respectively and is detachably connected to the pressing plate 2 and the support plate 3. The pressing plate 2 and the support plate 3 are both slidably connected to the support frame 1, and the pressing block 4 and the shaping mold 5 are both on the same axis.

[0026] According to the above structure, when in use, the staff installs the device at a designated position. When the fastener is hot-forged, the material is in the forming cavity 12, and the hydraulic rod 14 on the top of the pressing plate 2 is driven to move downward, and the pressing block 4 and the forming die body 8 are moved downward;

[0027] The forming die body 8 moves downward and is stuck in the forming cavity 12. The pressure of the forming die body 8 when it moves is used to extrude the material to form it. At the same time, the forming die body 8 is heated by the heating wire 10, so that the material is deformed by heat in the forming cavity 12. Combined with the pressure of the forming die body 8 when it moves, the material is limited by the forming cavity 12 to effectively avoid deformation during hot upsetting, thereby improving the material forming quality.

[0028] Furthermore, by providing the limiting sleeve 7 and the limiting plate 9 , the forming die body 8 can be supported to prevent the forming die body 8 from being deformed due to pressure and affecting the forming quality of the material in the forming cavity 12 .

[0029] Different from the prior art, the present application discloses a fastener hot upsetting anti-deformation forming die, in which the forming die body 8 is displaced downward and stuck in the forming cavity 12, and the material is extruded and formed by the pressure of the displacement of the forming die body 8. At the same time, the forming die body 8 is heated by the heating wire 10, so that the material is deformed by heat in the forming cavity 12. Combined with the pressure of the displacement of the forming die body 8 and the limitation of the forming cavity 12, the material can be effectively prevented from being deformed during hot upsetting, thereby improving the material molding quality.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
