Description

Technical Field

[0001] This utility model relates to the technical field of elastic centralizer tooling for stamping equipment, specifically to elastic centralizer tooling for stamping equipment. Background Technology

[0002] Elastic centralizer fixtures for stamping equipment are specially designed devices for assisting in the processing, positioning, and fixing of workpieces. They are widely used in various industrial manufacturing fields. Their core purpose is to improve processing efficiency, reduce manual operation, and protect workpieces from damage. Examples include elastic centralizer fixtures for wheelset stamping equipment, elastic centralizer fixtures for automatic spring loading machines, drill tool centralizer processing fixtures, and reference fixtures for centralizer sleeve processing. Elastic centralizer fixtures for stamping equipment play an important role in improving production efficiency, reducing manual operation, and protecting workpieces.

[0003] However, the existing stamping equipment's elastic stabilizer tooling usually resets the outer support assembly by the elastic contraction of the blank itself after the workpiece is fixed. However, the blank will deform after a long period of use, which will cause the outer support assembly to reset slowly or not reset properly, affecting the removal of the workpiece. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible centralizer tooling for stamping equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A stamping equipment elastic stabilizer fixture includes a mounting plate 101. The mounting plate 101 has mounting holes 102 at its four corners. A spring return cylinder 103 is fixedly installed at the center of the top of the mounting plate 101. A nitrogen spring 104 is fixedly installed inside the spring return cylinder 103. A stabilizing mechanism 105 is provided inside the spring return cylinder 103. The stabilizing mechanism 105 includes a central rod 106. The bottom end of the central rod 106 is movably installed inside the spring return cylinder 103. A nut 201 is fixedly installed on the upper side of the central rod 106.

[0025] With the above solution, the mounting plate can be fixed through the mounting holes, thereby fixing the rebound cylinder. The compression and rebound of the nitrogen spring can drive the center rod to reset. The pressure on the center rod can drive the overall assembly to perform external support work. The upper connecting rod can be fixed by fixing the nut to the center rod.

[0026] In this embodiment, preferably, the straightening mechanism 105 further includes an upper connecting plate 202, which is fixedly installed at the bottom of the nut 201. An upper rotating plate 203 is fixedly installed at the bottom of the upper connecting plate 202, and an upper pull rod 204 is movably installed on the outer side of the upper rotating plate 203.

[0027] The above solution allows the upper rotating plate to be supported by the upper connecting plate, and the upper tie rod to be installed via the upper rotating plate.

[0028] In this embodiment, preferably, an upper rotating hole 205 is provided in the middle of the upper side of the upper pull rod 204, an upper rotating pin 206 is movably installed through the upper rotating plate 203 in the upper rotating hole 205, and an upper arc mold 301 is fixedly installed on the outer side of the upper pull rod 204.

[0029] With the above scheme, an upper rotating pin is movably installed through the upper rotating hole through the upper rotating plate, which allows the upper side of the upper pull rod to rotate on the outside of the upper rotating plate via the rotating pin. The upper arc mold can support the blank externally when the upper pull rod is stretched outward, thereby fixing the workpiece to be processed.

[0030] In this embodiment, preferably, an upper gear 302 is fixedly installed at the bottom end of the upper pull rod 204, an upper connecting rotating hole 303 is provided in the middle of the upper gear 302, and a lower gear 304 is movably installed at the bottom end of the upper gear 302, with a lower connecting rotating hole 305 provided in the middle of the lower gear 304.

[0031] The above scheme allows the upper and lower connecting rods to expand outwards when under pressure by meshing and rotating the upper and lower gears.

[0032] In this embodiment, preferably, a connecting pin 306 is movably installed in the upper connecting pivot hole 303 and the lower connecting pivot hole 305, a pull rod 401 is fixedly installed at the bottom end of the lower gear 304, and a lower arc mold 402 is fixedly installed on the outside of the pull rod 401.

[0033] With the above scheme, connecting pins are movably installed in the upper and lower connecting holes, so that the upper and lower gears can remain stable and not fall off when they mesh and rotate. When the pull rod is extended outward, the lower arc mold can be extended outward to support the blank, thereby fixing the workpiece to be processed.

[0034] In this embodiment, preferably, the pull rod 401 is movably mounted on the lower side of the lower rotating plate 403, and a lower rotating hole 404 is provided in the middle of the lower side of the pull rod 401. A lower rotating pin 405 is movably mounted through the lower rotating plate 403 in the lower rotating hole 404.

[0035] With the above scheme, a lower rotating pin is movably installed through the lower rotating plate via the lower rotating hole, so that the lower side of the pull rod can rotate on the outside of the lower rotating plate through the rotating pin.

[0036] In this embodiment, preferably, the lower rotating plate 403 is fixedly installed on the top of the lower connecting plate 406, the lower connecting plate 406 has a central rod 106 movably installed in the middle, and the lower connecting plate 406 has a locking groove 501 in the middle.

[0037] The above solution allows the lower rotating plate to be supported and fixed by the lower connecting plate, and the bottom end of the blank to be engaged by the locking groove to keep it stable when supported externally.

[0038] In this embodiment, preferably, the lower connecting plate 406 has an assembly hole 502 at its top end, an assembly screw 503 is fixedly installed in the assembly hole 502, and a base plate 504 is fixedly installed at the bottom end of the lower connecting plate 406, with fixing holes 505 at the four corners of the top end of the base plate 504.

[0039] With the above solution, assembly screws can be used to fix the assembly through the assembly holes. The assembly screws can be used to assemble and fix the lower connecting plate to the base plate. The base plate can support the entire component, and the fixing holes can be used to fix the base plate.

[0040] In this embodiment, when using the elastic centralizer tooling for the stamping equipment, the user fixes the mounting plate 101 through the mounting hole 102 and the base plate 504 through the fixing hole 505 to the bottom of the hydraulic equipment. After fixing, the spring return cylinder 103 is located at the bottom of the base plate 504 and is centrally engaged with the center rod 106. At this time, the user inserts the blank through the upper connecting plate 202 and engages the bottom of the blank with the engaging groove 501. Then, the hydraulic equipment is started to press down on the center rod 106. The center rod 106 is pressed, causing the upper pull rod 204 and the lower pull rod 401 to be squeezed. The squeezing causes the upper gear 302 and the lower gear 304 to mesh and rotate through the connecting pin 306. During rotation, the upper side of the upper pull rod 204 rotates outside the upper rotating plate 203 through the upper rotating pin 206, and the lower side of the lower pull rod 401 rotates through the lower rotating pin 206. Pin 405 rotates on the outside of the lower rotating plate 403, causing the upper pull rod 204 and lower pull rod 401 to expand through the meshing rotation of the upper gear 302 and lower gear 304. During expansion, the upper arc mold 301 and lower arc mold 402 are driven to expand to the inside of the blank, so that the blank generates external support to achieve the required shape, which can fix and position the workpiece to be processed. After the center rod 106 is pressed down, its bottom end will slide inside the spring cylinder 103 and drive the nitrogen spring 104 to contract. When the workpiece is processed, the hydraulic equipment resets, causing the downward pressure of the center rod 106 to disappear. At this time, the contracted nitrogen spring 104 will reset and drive the center rod 106 and the external support assembly to reset. The reset of the nitrogen spring 104 can make the whole assembly quickly reset and ensure that the reset is in place, so that the processed workpiece can be quickly removed.
