[0001] This utility model relates to the field of leather bowl processing technology, and in particular to an automated punching tool. Background Technology

[0002] A piston cup is a lip seal installed on the piston of the master cylinder or wheel cylinder of the brake system. When the brake or clutch pedal is depressed, hydraulic oil pushes the piston forward, and the lip of the piston cup presses tightly against the inner wall of the cylinder body, creating a seal and building up hydraulic pressure to engage the brake or clutch wheel cylinders. When the pedal is released, the lip of the piston cup allows a small amount of hydraulic fluid to flow back, releasing the brake. It is a core component in hydraulic braking / clutch systems, ensuring sealing and generating pressure; its quality directly affects driving safety.

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] Example 1

[0021] like Figures 1 to 2 As shown in the figure, the present invention provides an automated punching tooling, including an upper mold assembly 1 and a lower mold assembly 2. In this embodiment, the sheet-like composite material to be punched can be placed between the upper mold assembly 1 and the lower mold assembly 2, and the sheet-like composite material can be punched into a cup structure by the upper mold assembly 1 and the lower mold assembly 2.

[0022] In this embodiment, please refer to Figures 2-5 The lower mold assembly 2 includes a base plate 201, on which a lower mold platform 202 is fixedly arranged, and a number of lower mold rods 401 are arranged in a matrix on the lower mold platform 202. Specifically, in this embodiment, the number of lower mold rods 401 is not limited, as long as it meets the actual application requirements. For example, in this embodiment, nine sets of lower mold rods 401 are provided. The upper mold assembly 1 includes a top plate 102 disposed on the lower mold assembly 2. An upper mold platform 103 is fixedly arranged on the top plate 102 in the direction of the lower mold assembly 2. On the side of the upper mold platform 103 away from the top plate 102, there are several sets of upper mold rods 302 that correspond one-to-one with the lower mold rods 401. The upper mold assembly 1 is connected to the lifting module that drives its lifting and lowering. It can be explained that in this embodiment, the sheet-like composite material to be punched can be placed on the lower mold rod 401. During punching, the upper mold assembly 1 can be driven to move towards the lower mold assembly 2 through the lifting module. The composite material is punched into a cup structure by the cooperation of the upper mold rod 302 and the lower mold rod 401. It should also be noted that this embodiment does not limit the specific structure of the upper mold rod 302 and the lower mold rod 401, as long as the actual cup structure required for molding is met.

[0023] As one embodiment of this invention, in order to facilitate the unloading of the punched leather cup structure, the upper mold assembly 1 is also provided with an ejection mechanism to eject the formed leather cup structure. It can be noted that after the leather cup structure of this embodiment is punched and formed, it can be ejected from the upper mold assembly 1 by the ejection mechanism to facilitate unloading and avoid the leather cup structure getting stuck on the mold rod.

[0024] Example 2

[0025] Based on Example 1, please refer to Figures 3-5 The lower mold assembly 2 also includes a lower support plate 4 disposed on the lower mold table 202. The lower support plate 4 has a lower mold groove 407 for the lower mold rod 401 to pass through. The lower mold table 202 is provided with a first buffer guide mechanism, which is connected to the lower support plate 4. It can be explained that in this embodiment, when punching the sheet composite material, as the lifting module drives the upper mold assembly 1 to move towards the lower mold assembly 2, the lower support plate 4 is displaced downwards by a certain distance under pressure, thereby causing the lower mold rod 401 to be pushed out from the lower mold groove 407, and then cooperates with the upper mold rod 302 to punch the sheet composite material. At this time, the first buffer guide mechanism is compressed by the pressure of the lower support plate 4 and generates elastic force. As the lifting module drives the upper mold assembly 1 to reset, the first buffer guide mechanism can drive the lower support plate 4 to reset. During the reset process, the lower support plate 4 can lift the formed cup structure to separate from the lower mold rod 401 to avoid it getting stuck on the lower mold rod 401.

[0026] As one possible implementation of this embodiment, the upper mold assembly 1 further includes an upper support plate 301, which is disposed on the side of the upper mold platform 103 near the lower mold assembly 2. The upper support plate 301 has an upper mold groove 303 for the upper mold rod 302 to pass through. A second buffer guide mechanism is provided between the upper mold platform 103 and the upper support plate 301. It can be noted that during the punching process, the upper support plate 301 moves towards the lower support plate 4 under the driving action of the lifting module to press the sheet composite material between the upper support plate 301 and the lower support plate 4. Between the support plates 4, during the process of the lower mold rod 401 being pushed out from the lower mold groove 407, the upper mold rod 302 is simultaneously pushed out from the upper mold groove 303. During this process, the upper support plate 301 is displaced a distance toward the upper mold table 103 to compress the second buffer guide mechanism and generate elastic force. Therefore, when the lifting module drives the upper mold assembly 1 to reset, the second buffer guide mechanism can simultaneously drive the upper support plate 301 to reset. During the reset process, the formed cup structure is pushed to separate from the upper mold rod 302 to avoid it getting stuck on the upper mold assembly 1.

[0027] In this embodiment, an upper pressure plate 3 is also provided on the side of the upper support plate 301 near the upper mold table 103. The upper pressure plate 3 is connected to the upper mold table 103 through a third buffer guide mechanism. It can be explained that during the process of the lower mold rod 401 and the upper mold rod 302 cooperating to stamp the composite material profile cup structure, the upper pressure plate 3 can play the role of pressing and limiting the convex ring on the cup structure to ensure the quality of the cup structure forming. In the initial state, the upper pressure plate 3 and the upper support plate 301 are in a close fit. During the mold closing process, the lower mold rod 401 can push the upper pressure plate 3 to separate from the upper support plate 301. At this time, the third buffer guide mechanism contracts and generates elastic force. After the forming is completed, the third buffer guide mechanism can drive the upper pressure plate 3 to reset, and then push the formed cup structure to separate from the upper mold rod 302 through the upper pressure plate 3.

[0028] Specifically, the first buffer guide mechanism includes a first guide rod 402 fixed on the lower mold plate 202, a lower support plate 4 slidably sleeved on the first guide rod 402, and a first limiting block 404 fixedly arranged at the top end of the first guide rod 402. The first guide rod 402 is provided with a first spring 403, one end of the first spring 403 is fixed to the lower support plate 4, and the other end is fixed to the lower mold plate 202. It can be explained that when the lower support plate 4 moves downward, it can compress the first spring 403 and generate elastic force, which facilitates subsequent driving of its reset.

[0029] In addition, the upper support plate 301 is provided with a first through groove 309 for embedding the first limiting block 404; specifically, when the upper support plate 301 and the lower support plate 4 are stamping the composite material, the first limiting block 404 can be embedded in the first through groove 309 to avoid interference.

[0030] The second buffer guide mechanism includes a second guide rod 304 fixed on the upper die table 103. The other end of the second guide rod 304 slides through the upper support plate 301 and is fixedly connected to the second limiting block 310. A second spring 305 is provided on the second guide rod 304. One end of the second spring 305 is fixed to the upper support plate 301, and the other end is fixed to the upper die table 103. It can be explained that during the punching process, as the upper support plate 301 moves toward the upper die table 103, the upper support plate 301 can compress the second spring 305 and generate elastic force, so as to drive it to reset in the future.

[0031] In this embodiment, the lower support plate 4 is provided with a second through groove 405 for embedding the second limiting block 310; specifically, during punching, the second limiting block 310 can be embedded in the second through groove 405 to prevent interference.

[0032] Please see Figures 3-5 The third buffer guide mechanism includes a limiting cylinder 306 fixed on the upper mold table 103, an upper pressure plate 3 slidably sleeved on the limiting cylinder 306, a third spring 307 provided on the limiting cylinder 306, one end of the third spring 307 fixed to the upper mold table 103, and the other end fixed to the upper pressure plate 3. A limiting rod 311 that is inserted into the limiting cylinder 306 is fixedly arranged on the upper support plate 301. The limiting rod 311 is fixed to the upper support plate 301 by a locking block 308. It can be noted that when the upper pressure plate 3 moves away from the upper support plate 301 in this embodiment, the upper pressure plate 3 can compress the limiting cylinder 306 and generate elastic force, so as to facilitate the subsequent driving of the upper pressure plate 3 to reset.

[0033] As one embodiment of this invention, the lower support plate 4 is also provided with a third through groove 406 for embedding the locking block 308; specifically, during punching, the locking block 308 can be embedded in the third through groove 406 to prevent interference.

[0034] In this embodiment, the lifting module includes a lifting plate 101 fixed on the top plate 102. The lifting plate 101 is connected to the lifting mechanism to drive the upper mold assembly 1 to lift. Specifically, the lifting mechanism in this embodiment can be an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. This embodiment does not limit the specific type of cylinder.

[0035] It should also be noted that the base plate 201 of the lower mold assembly 2 in this embodiment is slidably mounted on the worktable via a slide rail; specifically, during the loading and unloading process, the operator can pull the lower mold assembly 2 horizontally along the slide rail to facilitate loading and unloading.

[0036] The working principle of this utility model is as follows: the operator pulls the lower mold assembly 2 out along the slide rail, then places the sheet-like composite material to be punched on the lower support plate 4, then resets the lower mold assembly 2, and drives the upper mold assembly 1 to move towards the lower mold assembly 2 through the lifting module. The upper mold rod 302 and the lower mold rod 401 cooperate to punch the composite material into a cup structure. Finally, the lower mold assembly 2 is pulled out again to complete the material unloading.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
