Description

Technical Field

[0001] This utility model relates to the field of steel ring stamping and forming, and more specifically, to a stamping and forming die for steel ring processing. Background Technology

[0002] Steel rims (such as automotive rims, industrial transmission rims, and engineering machinery rims) are typical products made by stamping metal sheets into ring-shaped or disc-shaped parts. Their processing accuracy (such as roundness, radial runout, and wall thickness uniformity) directly affects the operational stability and safety of the equipment. Stamping is the core process in steel rim manufacturing. Steel rim stamping uses metal sheets (such as cold-rolled steel sheets, galvanized sheets, stainless steel sheets, and spring steel) as raw materials, applies pressure to the sheets using stamping dies, causing plastic deformation, and ultimately obtaining a ring-shaped steel rim with specific shape, size, and mechanical properties.

[0003] However, in the existing steel ring processing stamping die, after the steel ring is stamped, it is removed manually. This method is convenient for removing the steel ring directly. If tools are used to remove it, the steel ring is easily damaged. Furthermore, after multiple stamping operations, the punch and cutting tool of the steel ring processing stamping die are easily damaged, resulting in insufficient die closing accuracy and affecting the stamping effect of the steel ring. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for stamping and forming dies used in steel ring processing.

[0005] According to a first aspect of this utility model, a stamping die for steel ring processing is provided, comprising: a base plate, a side plate, a top plate, a support column, and a base. An ejection mechanism is provided below the base plate, and a protective mechanism is provided above the base plate. The ejection mechanism includes a lower die, which is fixedly connected to the upper end of the base plate. A cylinder is fixedly connected to the bottom end of the top plate, and an upper die is connected to the bottom output end of the cylinder. An ejection plate is provided in the internal cavity of the lower die. A housing is fixedly connected to the upper end of the base, and a servo motor is mounted on the upper end of the housing. A main gear is fixedly connected to the output end of the servo motor. A secondary gear is connected to the surface of the main gear through tooth meshing. A threaded rod is fixedly connected to the upper end of the secondary gear. The upper end of the threaded rod is rotatably disposed at the bottom end of the base plate. A movable seat is threadedly connected to the surface of the threaded rod, and a push rod is fixedly connected to the upper end of the movable seat. The push rod and the ejection plate are assembled and connected by bolts.

[0006] Preferably, a support plate is fixedly connected to the bottom end of the movable seat, a telescopic support rod is fixedly connected to the bottom end of the support plate, and the telescopic support rod is fixedly connected to the upper end of the base.

[0007] Preferably, the bottom ends of the main gear and the auxiliary gear are connected to the inner wall of the housing via a supporting rotating column and a bearing seat.

[0008] Preferably, the protective mechanism includes a punch mold, which is assembled at the bottom end of the upper mold. A mounting post is fixedly connected to the upper end of the upper mold. The mounting post is engaged in a mounting cavity opened inside the upper mold. A mounting groove is opened inside the mounting post and is located inside the upper mold. A fastening bolt is installed inside the mounting groove.

[0009] Preferably, a ball bearing guide seat is fixedly connected to the side wall of the upper mold. The ball bearing guide seat is slidably disposed inside the slide rail by ball bearings. The slide rail is opened inside the guide rail body, and the guide rail body is fixedly connected to the upper end of the base plate.

[0010] Preferably, the guide rail body is provided in two sets, and the guide rail bodies are symmetrically arranged along the central axis of the upper mold.

[0011] 1. This utility model utilizes the cooperation of a lower mold, cylinder, upper mold, housing, servo motor, main gear, secondary gear, threaded rod, moving seat, and ejector rod to place the steel ring material inside the lower mold. Activating the cylinder causes the upper mold to move downwards to close the mold, stamping the steel ring. After stamping, the servo motor is activated, driving the main gear to rotate. Through gear meshing, the secondary gear rotates synchronously, which in turn drives the threaded rod to rotate. The threaded rod, in turn, causes the moving seat to move upwards, causing the ejector rod to move upwards synchronously, pushing the ejector plate to eject the steel ring. This allows for convenient ejection of the steel ring, avoiding the inconvenience of removing stamped steel rings. The steel ring processing and stamping mold allows for convenient ejection of the steel ring. The bottom ejection unit facilitates the ejection of the ejector plate inside the lower mold, making it easy to remove the steel ring and preventing the stamped steel ring from being difficult to remove for processing in a timely manner. This improves the practicality and functionality of the device.

[0012] 2. This utility model uses the cooperation of a punch, mounting column, mounting groove, fastening bolt, ball bearing guide seat, slide rail and guide rail body to assemble and set up the upper die and punch, which can be easily disassembled and replaced. This avoids wear of the punch due to repeated stamping, which may cause failure in the next die closing stamping. During disassembly and assembly, the fastening bolt can be directly moved out of the mounting groove with a tool for easy disassembly and assembly. This allows the punch of the steel ring processing stamping die to be replaced, avoiding the impact of punch wear on stamping, and improving the practicality and convenience of the device.

[0022] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0023] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0024] like Figure 1-4 As shown, one embodiment of this utility model is provided:

[0025] A stamping die for steel ring processing. The base plate 111, side plate 112, top plate 113, support column 114, base 115, cylinder 212 and servo motor 215 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art.

[0026] The system includes: a base plate 111, side plates 112, a top plate 113, support columns 114, and a base 115. An ejection mechanism 2 is located below the base plate 111, and a protective mechanism 3 is located above the base plate 111. The ejection mechanism 2 includes a lower mold 211, which is fixedly connected to the upper end of the base plate 111. A cylinder 212 is fixedly connected to the bottom end of the top plate 113, and the bottom output end of the cylinder 212 is connected to the upper mold 213. An ejection plate is located in the internal cavity of the lower mold 211. A housing 2 is fixedly connected to the upper end of the base 115. 14. A servo motor 215 is installed on the upper end of the housing 214. A main gear 216 is fixedly connected to the output end of the servo motor 215. A secondary gear 217 is connected to the surface of the main gear 216 through tooth meshing. A threaded rod 218 is fixedly connected to the upper end of the secondary gear 217. The upper end of the threaded rod 218 is rotatably set at the bottom end of the base plate 111. A movable seat 219 is connected to the surface of the threaded rod 218 through threads. A push rod 220 is fixedly connected to the upper end of the movable seat 219. The push rod 220 is assembled and connected to the ejector plate by bolts.

[0027] When using this steel ring to process the stamping die, the steel ring material is injected into the lower die 211, and the cylinder 212 is started to drive the upper die 213 to move downward to close the die and stamp the steel ring. After stamping, the servo motor 215 can be started to drive the main gear 216 to rotate. Under the meshing of the teeth, the auxiliary gear 217 is driven to rotate synchronously, which in turn drives the threaded rod 218 to rotate. Under the action of the thread, the moving seat 219 is driven to move upward, and the ejector rod 220 moves upward synchronously, which pushes the ejector plate to perform the ejection operation. This allows the steel ring to be easily ejected and removed, avoiding the inconvenience of removing the stamped steel ring.

[0028] The bottom of the movable base 219 is fixedly connected to a support plate 221, and the bottom of the support plate 221 is fixedly connected to a telescopic support rod 222, which is fixedly connected to the upper end of the base 115.

[0029] When the movable seat 219 moves, the telescopic support rod 222 extends and retracts to provide stable support and prevent the movable seat 219 from rotating.

[0030] The bottom ends of the main gear 216 and the auxiliary gear 217 are connected to the inner wall of the housing 214 via a supporting rotating column and a bearing seat.

[0031] The bottom ends of the main gear 216 and the auxiliary gear 217 are connected to the inner wall of the housing 214 through a support rotating column and a bearing seat, making the rotation of the main gear 216 and the auxiliary gear 217 more stable.

[0032] The protective mechanism 3 includes a punch 311, which is assembled at the bottom of the upper mold 213. The upper end of the upper mold 213 is fixedly connected to a mounting post 312, which is engaged in a mounting cavity opened inside the upper mold 213. The mounting post 312 has a mounting groove 313 inside, which is opened inside the upper mold 213. A fastening bolt 314 is installed inside the mounting groove 313.

[0033] When using this steel ring to process stamping molds, the upper mold 213 and the punch 311 are assembled and set up for easy disassembly and replacement, avoiding wear of the punch 311 after multiple stampings, which could cause failure in the next mold closing stamping. During disassembly and assembly, the fastening bolt 314 can be directly moved out of the mounting slot 313 using tools for easy disassembly and assembly.

[0034] The upper mold 213 has a ball guide rail seat 315 fixedly connected to its side wall. The ball guide rail seat 315 is slidably disposed inside the slide rail 316 by ball. The slide rail 316 is opened inside the guide rail body 317. The guide rail body 317 is fixedly connected to the upper end of the base plate 111.

[0035] When the cylinder 212 drives the upper mold 213 to move downward to close the mold, two linear ball bearing guides are added between the lower mold 211 and the upper mold 213. The linear ball bearing guides are composed of a servo motor 215 and a secondary gear 217, which eliminates the clearance error of traditional guide pillars and guide sleeves.

[0036] Two sets of guide rail bodies 317 are provided, and the guide rail bodies 317 are symmetrically arranged along the central axis of the upper mold 213.

[0037] Working principle:

[0038] When using this steel ring to process the stamping die, the steel ring material is injected into the lower die 211, and the cylinder 212 is started to drive the upper die 213 to move downward to close the die and stamp the steel ring. After stamping, the servo motor 215 can be started to drive the main gear 216 to rotate. Under the meshing of the teeth, the auxiliary gear 217 is driven to rotate synchronously, which in turn drives the threaded rod 218 to rotate. Under the action of the thread, the moving seat 219 is driven to move upward, and the ejector rod 220 moves upward synchronously, which pushes the ejector plate to perform the ejection operation. This allows the steel ring to be easily ejected and removed, avoiding the inconvenience of removing the stamped steel ring.

[0039] When using this steel ring to process stamping molds, the upper mold 213 and the punch 311 are assembled and set up for easy disassembly and replacement, avoiding wear of the punch 311 after multiple stampings, which could cause failure in the next mold closing stamping. During disassembly and assembly, the fastening bolt 314 can be directly moved out of the mounting slot 313 using tools, and the operation is then complete.
