Description

Technical Field

[0001] This utility model relates to a stamping die, and more particularly to a precision stamping die used in stamping equipment. Background Technology

[0002] Precision stamping dies are tooling equipment used for precision machining of metal or non-metal materials. By cooperating with stamping equipment (such as hydraulic presses and mechanical presses), they cause the material to undergo plastic deformation or separation under pressure, thereby obtaining high-precision, high-surface-quality finished parts. In modern manufacturing, precision stamping is a key process for parts production and is widely used in electronics, automobiles, aerospace and other fields.

[0003] Chinese patent CN114378168A discloses a stamping forming machine tool for precision mold production that facilitates automatic material unloading. It includes a fixed assembly with a movable plate inside. The movable plate has a transverse groove inside, and a rotating disk is slidably connected inside the groove. After stamping, an electromagnet is energized, further ejecting the mold from the lower die. This achieves automatic material unloading, preventing overheating of the mold and potential burns to workers, thus improving manufacturing safety.

[0004] Chinese patent CN210676613U discloses a precision stamping mold, including a lower mold base and an upper mold base. The lower mold base has mounting grooves at its four corners, and guide posts are fixedly connected inside each of the four mounting grooves. The upper mold base has guide sleeves fixedly connected at its four corners, which are sleeved around the guide posts. A mounting plate is slidably mounted on the top of the lower mold base, and a punch is mounted on the mounting plate. The punch is mounted on the mounting plate by passing bolts through the mounting plate and tightening them into the mounting holes. When replacing the punch, the bolts are unscrewed to remove and replace it.

[0005] When existing precision stamping molds use a direct free-fall collection method, the lack of buffer and guiding devices results in a large impact force when the finished part lands. This not only generates high-decibel impact noise but also easily causes damage to the internal structure. Especially for precision stamping parts, such damage can directly lead to functional failure. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that when existing precision stamping forming dies adopt the direct free fall collection method, due to the lack of buffer and guiding devices, the impact force of the finished parts is large when they land. This not only generates high-decibel impact noise, but also easily causes damage to the internal structure. Especially for precision stamping parts, such damage will directly lead to functional failure.

[0007] To solve the above problems, this utility model provides a precision stamping forming mold, including a protective chamber assembly, a stamping assembly at the inner end of the protective chamber assembly, a material storage assembly below the protective chamber assembly, a receiving assembly between the material storage assembly and the protective chamber assembly, and a noise reduction and sound insulation assembly in cooperation with the protective chamber assembly and the material storage assembly.

[0008] The protective chamber assembly includes an outer frame of the chamber and a stamping assembly including a stamping equipment body disposed on the lower inner wall of the outer frame of the chamber. A hydraulic actuator is fixedly connected to the upper end of the outer frame of the chamber. A mold body is fixedly connected to the inner end of the stamping equipment body. An electric pusher rod is fixedly connected to the rear inner wall of the outer frame of the chamber. The output end of the hydraulic actuator is connected to the mold body. A discharge port is opened on the lower front side of the outer frame of the chamber. The finished part is disposed inside the mold body.

[0009] The receiving assembly includes L-shaped crossbars fixedly connected to the left and right sides of the lower end of the outer frame of the hopper. A rotating horizontal shaft is installed between the two L-shaped crossbars. A motor is connected to the rotating horizontal shaft. Multiple convex fan plates arranged in a ring at equal intervals are fixedly connected to the outer end of the rotating horizontal shaft. Multiple arc-shaped electromagnetic strips are fixedly connected to the outer end of the rotating horizontal shaft. The multiple arc-shaped electromagnetic strips are located between two adjacent convex fan plates. Protruding contact columns are symmetrically fixedly connected to the left and right ends of the lower side of the L-shaped crossbars. Multiple protruding inductive switches are fixedly connected to the left and right sides of the rotating horizontal shaft. The multiple protruding inductive switches and the corresponding arc-shaped electromagnetic strips are interconnected. The two protruding contact columns correspond to the protruding inductive switches directly above them.

[0010] In the aforementioned precision stamping mold, efficient, safe, and low-noise production is achieved through the coordinated operation of the protective chamber assembly, stamping assembly, receiving assembly, storage assembly, and noise reduction and sound insulation assembly.

[0011] As a further improvement of this application, the left and right ends of the outer frame of the warehouse are symmetrically hinged with side panels, and the lower ends of the side panels are fixedly connected with multiple shielding curtains, which are arranged horizontally at equal intervals.

[0012] As a further improvement of this application, the storage assembly includes a storage base frame, and a plurality of follower spring supports are fixedly connected to the lower inner wall of the storage base frame, and the plurality of follower spring supports are distributed in a rectangular manner.

[0013] As a further improvement of this application, the rotating horizontal axis is located directly below the discharge port, and the finished part falls through the hydraulic device into the arc-shaped electromagnetic strip and is collected in the storage bottom frame.

[0014] As another improvement of this application, the rotating horizontal axis is located directly below the discharge port, and the finished part falls through the hydraulic device into the arc-shaped electromagnetic strip and is collected in the storage bottom frame.

[0015] As a further improvement to this application, the noise reduction and sound insulation component includes a noise reduction panel fixedly connected to the outer frame of the silo and the bottom frame of the storage material, the noise reduction panel including a sound insulation layer.

[0016] As a further improvement to this application, a sound-absorbing cotton layer is fixedly connected to the outer side of the sound insulation board layer, and a buffer contact surface layer is fixedly connected to the outer end of the sound-absorbing cotton layer.

[0017] In summary, this solution ensures finished product accuracy through the cooperation of hydraulic units and the die body in the stamping assembly; improves efficiency through an electric pusher and unloading rod; reduces the risk of debris splashing and blocks equipment operating noise through the side panels and shielding curtains of the protective chamber assembly; achieves automated transmission through a rotating horizontal shaft drive structure in the receiving assembly, combined with inductive control for precise material unloading, reducing unloading noise and finished product defect rate; absorbs the impact energy of unloading through the elastic buffer structure of the material receiving assembly, reducing unloading noise and improving the finished product qualification rate; and significantly reduces the overall noise of the equipment through the three-layer composite structure of the noise reduction and sound insulation assembly, meeting industrial noise standards while reducing the impact of vibration on stamping accuracy, thus comprehensively improving the overall performance and production efficiency of the die.

[0027] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] First implementation method:

[0029] Figures 1-7 A precision stamping die is shown, including a protective chamber assembly 1, a stamping assembly 2 is provided at the inner end of the protective chamber assembly 1, a material storage assembly 4 is provided below the protective chamber assembly 1, a material receiving assembly 3 is provided between the material storage assembly 4 and the protective chamber assembly 1, and a noise reduction and sound insulation assembly 5 is provided in cooperation with the protective chamber assembly 1 and the material storage assembly 4.

[0030] The protective chamber assembly 1 includes a chamber outer frame 100, and the stamping assembly 2 includes a stamping equipment body 200 disposed on the lower inner wall of the chamber outer frame 100. A hydraulic actuator 203 is fixedly connected to the upper end of the chamber outer frame 100, and a mold body 201 is fixedly connected to the inner end of the stamping equipment body 200. An electric pusher and unloading rod 205 is fixedly connected to the rear inner wall of the chamber outer frame 100. The output end of the hydraulic actuator 203 is connected to the mold body 201. A discharge port 202 is opened on the lower front side of the chamber outer frame 100, and a finished part 204 is disposed inside the mold body 201.

[0031] The receiving assembly 3 includes L-shaped crossbars 300 fixedly connected to the left and right sides of the lower end of the outer frame 100 of the hopper. A rotating horizontal shaft 301 is installed between the two L-shaped crossbars 300. A motor is connected to the rotating horizontal shaft 301. Multiple convex fan plates 302 arranged in a ring at equal intervals are fixedly connected to the outer end of the rotating horizontal shaft 301. Multiple arc-shaped electromagnetic strips 303 are fixedly connected to the outer end of the rotating horizontal shaft 301. The multiple arc-shaped electromagnetic strips 303 are respectively located between two adjacent convex fan plates 302. Protruding contact columns 305 are symmetrically fixedly connected to the left and right ends of the lower side of the L-shaped crossbars 300. Multiple protruding induction switches 304 are fixedly connected to the left and right sides of the rotating horizontal shaft 301. The multiple protruding induction switches 304 and the corresponding arc-shaped electromagnetic strips 303 are linked together. The two protruding contact columns 305 correspond to the protruding induction switches 304 directly above them.

[0032] The left and right ends of the outer frame 100 of the warehouse are symmetrically hinged with side panels 101, and the lower ends of the side panels 101 are fixedly connected with multiple curtains 102, which are arranged horizontally at equal intervals.

[0033] The storage assembly 4 includes a storage base frame 400. Multiple follower spring supports 401 are fixedly connected to the lower inner wall of the storage base frame 400. The multiple follower spring supports 401 are arranged in a rectangular pattern. The rotating horizontal axis 301 is located directly below the discharge port 202. The finished product 204 passes through the hydraulic device 203, falls above the arc-shaped electromagnetic strip 303, and is collected in the storage base frame 400. The rotating horizontal axis 301 is located directly below the discharge port 202. The finished product 204 passes through the hydraulic device 203, falls above the arc-shaped electromagnetic strip 303, and is collected in the storage base frame 400.

[0034] Figures 1-6 The stamping assembly 2 is shown with the outer frame 100 of the storage chamber as the mounting base. The hydraulic actuator 203 is fixed to the upper end of the outer frame 100 of the storage chamber, and its output end is connected to the mold body 201 to provide power for stamping. When the raw material is placed into the mold body 201, the hydraulic actuator 203 drives the mold body 201 to apply pressure to the raw material. The finished part 204 formed by stamping is temporarily stored in the mold body 201. After stamping is completed, the electric pusher rod 205 is activated to push the finished part 204 out of the mold body 201 and let it fall through the discharge port 202 on the lower front side of the outer frame 100 of the storage chamber assembly 1. The side panels 101 and the lower shielding curtain 102 hinged to the left and right ends of the outer frame 100 of the storage chamber assembly 1 can prevent debris from flying during the stamping process, protect the safety of the operators and maintain the cleanliness of the working environment, and initially reduce the noise transmission during equipment operation.

[0035] The L-shaped crossbars 300 of the receiving assembly 3 are fixed to both sides of the lower end of the outer frame 100 of the hopper. The rotating horizontal shaft 301 is installed between the two L-shaped crossbars 300 and is driven to rotate by an external motor. The outer end of the rotating horizontal shaft 301 has equidistantly distributed annular convex fan plates 302 and arc-shaped electromagnetic strips 303. They work together during rotation. When the finished product 204 falls from the discharge port 202, the arc-shaped electromagnetic strips 303 use electromagnetic force to attract the falling finished product 204 and rotate with the rotating horizontal shaft 301 for transmission. At the same time, the convex fan plates 302 on both sides of the rotating horizontal shaft 301... The induction switch 304 is linked with the arc-shaped electromagnetic strip 303. When the arc-shaped electromagnetic strip 303 rotates to the position corresponding to the protruding contact column 305 on the lower side of the L-shaped crossbar 300, which is directly above the direction of the material storage, the protruding induction switch 304 is triggered, controlling the arc-shaped electromagnetic strip 303 to turn off the electromagnetic force, so that the finished part 204 falls accurately into the material storage component 4 below. The electromagnetic adsorption and release mechanism avoids the finished part 204 falling freely and impacting, eliminates some of the impact noise caused by the height difference of the falling material, and at the same time ensures the safety of the finished part 204 falling.

[0036] Within the storage base frame 400 of the storage assembly 4, multiple rectangularly distributed follower spring supports 401 provide elastic support for the height-adjustable top plate 402. As finished parts 204 continuously fall from the receiving assembly 3 into the storage base frame 400 and stack on the height-adjustable top plate 402, the top plate compresses the follower spring supports 401 under the action of gravity and moves downward. The follower spring supports 401 and the height-adjustable top plate 402 of the storage assembly 4 form an elastic buffer structure, which can dynamically adapt to the stacking of different numbers of finished parts, further eliminating high drop difference, thereby reducing the drop impact noise caused by it, and avoiding deformation and damage of finished parts due to hard landing. It is especially suitable for storing precision parts.

[0037] Second implementation method:

[0038] Figure 1 , Figure 7This invention discloses a precision stamping die. A noise reduction and sound insulation component 5 includes a noise reduction plate 500 fixedly connected within the outer frame 100 of the storage chamber and the bottom frame 400 of the storage chamber. The noise reduction plate 500 includes a sound insulation layer 501, a sound-absorbing cotton layer 502 fixedly connected to the outer side of the sound insulation layer 501, and a buffer contact surface layer 503 fixedly connected to the outer end of the sound-absorbing cotton layer 502. The noise reduction plate 500 of the noise reduction and sound insulation component 5 is respectively disposed within the outer frame 100 of the storage chamber and the bottom frame 400 of the storage chamber. The sound insulation layer 501 blocks the propagation of sound waves, the sound-absorbing cotton layer 502 absorbs sound wave energy through its porous structure, and the buffer contact surface layer 503 further reduces the impact of external vibrations on the equipment. The three layers work synergistically to effectively reduce the noise and vibration generated during the stamping process, significantly improve the acoustic environment of the workshop, reduce noise pollution to the surrounding area, and reduce the impact of equipment vibration on the precision stamping accuracy. The noise reduction and sound insulation component 5 can be used as an optional component in specific environments of noise-sensitive areas.

[0039] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
