Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a stamping die for the upper section of a C-pillar reinforcement plate. Background Technology

[0002] Cars are a very common means of transportation in modern daily life. Since the C-pillar of a car mainly serves a supporting and protective function, it requires high strength. In the manufacturing process of the C-pillar, reinforcing stamping dies are generally used to assist in the stamping and forming of the C-pillar.

[0003] A search of existing Chinese patent technology reveals a "stamping die for a C-pillar reinforcement plate of an automobile," with publication number "CN221362237U." This device's stamping head overlaps with the interior of the clearance hole, and the lower surface of the reinforcement plate pushes the supporting rubber pad downwards into the mounting hole. The supporting rubber pad supports the edge of the punched hole in the reinforcement plate, reducing wrinkling and deformation caused by uneven force at the punched hole location during the stamping process. However, before placing the stamping material, the operator needs to adjust its angle and position to ensure correct forming during stamping. During the stamping process, misalignment of the material may occur, leading to defects in the reinforcement. Utility Model Content

[0004] Based on this, it is necessary to address the issue that stamping materials require adjustment of their angle and position before placement to ensure proper stamping. During the stamping process, misalignment of the material parts may occur, leading to defects in the reinforcing parts. Therefore, a stamping die for the upper section of a C-pillar reinforcing plate is provided, comprising: two stamping die bases, each with multiple telescopic rods fixedly connected to opposite sides, the telescopic rods arranged in an array; and a guiding mechanism mounted on the surface of the lower stamping die base. The guiding mechanism includes a lifting component mounted on the surface of the lower stamping die base, a guiding component connected to the surface of the lifting component away from the adjacent telescopic rods, and a sliding component disposed on the surface of the guiding component away from the adjacent lifting component.

[0005] In one embodiment, the lifting assembly includes a limiting plate disposed between the two stamping die holders. Two guide rods are fixedly connected to the lower end of the limiting plate. The guide rods are fixedly connected to the upper end of the lower stamping die holder. A sliding tube is slidably connected to the surface of each guide rod, and a spring is sleeved on the surface of each guide rod. The limiting plate restricts the area where the sliding tube slides on the surface of the guide rod.

[0006] In one embodiment, the guiding assembly includes a connecting rod fixedly connected to the side of the two sliding tubes away from the adjacent telescopic rod. Two side guide plates are fixedly connected to the side of the connecting rod away from the sliding tubes, and a guide groove is formed between the two side guide plates. The combination of the connecting rod and the side guide plates provides good guiding effect.

[0007] In one embodiment, the sliding assembly includes a sliding frame slidably connected to the surface of the upper side guide plate. A guide strip is fixedly connected to the inner side of the sliding frame, and a clamping base plate is fixedly connected to the side of the sliding frame away from the guide strip. A clamping upper plate is provided at the upper end of the clamping base plate. The sliding frame and the guide strip can cooperate with the guiding assembly to form a stable guiding effect.

[0008] In one embodiment, a contact disc is fixedly connected to the lower end of the sliding tube, and the contact disc is slidably connected to the surface of the adjacent guide rod. The contact disc moves synchronously with the sliding tube.

[0009] In one embodiment, the upper end of the spring is fixedly connected to the lower end of the contact disc, and the lower end of the spring abuts against the surface of the stamping die base. The spring assists the sliding tube in driving the sliding assembly to move longitudinally.

[0010] In one embodiment, the lower end of the connecting rod is fixedly connected to a plurality of support ribs, which are fixedly connected to the surface of the adjacent side guide plate. The provided support ribs provide good support for the sliding assembly during movement.

[0011] In one embodiment, two connecting bolts are fixedly connected to the lower end of the upper clamping plate, and the lower ends of the connecting bolts penetrate through the lower clamping base plate and extend to the lower end of the lower clamping base plate. The lower clamping base plate and the upper clamping plate can form a good clamping effect on the sheet material to be conveyed. Beneficial effects

[0012] The aforementioned C-pillar reinforcement plate upper stamping die has a limiting plate that restricts the sliding tube's sliding area on the guide rod surface. A spring assists the sliding tube in driving the sliding component to move longitudinally, allowing the material to be moved out after stamping. This maintains the stability of the stamping process and ensures that the material's conveying position does not vary significantly. This reduces the occurrence of misalignment in the stamped material parts and minimizes defects in the stamped workpieces.

[0013] The combination of guide components and sliding components forms a guiding function, while the cooperation of guide grooves, sliding frames, and guide strips forms a stable guiding function. The clamping base plate and clamping top plate can form a good clamping function for the sheet metal to be conveyed, ensuring that the position of the stamped parts does not vary greatly, reducing the misalignment of stamped material parts, and reducing defects in stamped workpieces.

[0023] The following is combined Figures 1-5 This invention describes the upper section stamping die for the C-pillar reinforcing plate.

[0024] In one embodiment, a C-pillar reinforcing plate upper stamping die includes: two stamping die bases 1, each of which is fixedly connected to a plurality of telescopic rods 2, which are arranged in an array; a guide mechanism 3, which is mounted on the surface of the lower stamping die base 1; wherein, the guide mechanism 3 includes a lifting component 31 mounted on the surface of the lower stamping die base 1, a guide component 32 is connected to the surface of the lifting component 31 away from the adjacent telescopic rod 2, and a sliding component 33 is provided on the surface of the guide component 32 away from the adjacent lifting component 31;

[0025] like Figure 1-4 As shown, the lifting assembly 31 includes a limiting plate 312 disposed between two stamping die bases 1. The lower end of the limiting plate 312 is fixedly connected to two guide rods 311. The guide rods 311 are fixedly connected to the upper end of the lower stamping die base 1. A sliding tube 314 is slidably connected to the surface of the guide rods 311. A spring 315 is sleeved on the surface of the guide rods 311. A contact disc 313 is fixedly connected to the lower end of the sliding tube 314. The contact disc 313 is slidably connected to the surface of the adjacent guide rods 311. The upper end of the spring 315 is fixedly connected to the lower end of the contact disc 313. The lower end of the spring 315 abuts against the surface of the stamping die base 1.

[0026] The guide assembly 32 includes a connecting rod 321 fixedly connected to the side of the two sliding tubes 314 away from the adjacent telescopic rod 2. Two side guide plates 322 are fixedly connected to the side of the connecting rod 321 away from the sliding tubes 314. A guide groove 324 is formed between the two side guide plates 322. A plurality of support ribs 323 are fixedly connected to the lower end of the connecting rod 321. The support ribs 323 are fixedly connected to the surface of the adjacent side guide plates 322.

[0027] In this embodiment, the device restricts the sliding area of ​​the sliding tube 314 on the surface of the guide rod 311 by setting the limiting plate 312. The spring 315 can assist the sliding tube 314 in driving the sliding component 33 to move longitudinally, so that the material can be assisted to be removed after the plate is stamped, maintaining the stability of the stamping removal and improving the working effect of the material stamping.

[0028] The contact disc 313 moves synchronously with the sliding tube 314, and the contact disc 313 assists the spring 315 in generating good elastic potential energy. This ensures that the spring 315 deforms under pressure, generating elastic potential energy. The device forms a good guiding effect through the combination of the connecting rod 321 and the side guide plate 322. The supporting rib 323 provides good support for the sliding component 33 during movement, and the guide groove 324 assists in guiding the sliding component 33, ensuring that the material conveying position does not change significantly and improving the material pressing effect.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the sliding assembly 33 includes a sliding frame 331 slidably connected to the surface of the upper guide plate 322. A guide strip 332 is fixedly connected to the inner side of the sliding frame 331. A clamping base plate 333 is fixedly connected to the side of the sliding frame 331 away from the guide strip 332. A clamping upper plate 334 is provided at the upper end of the clamping base plate 333. Two connecting bolts 335 are fixedly connected to the lower end of the clamping upper plate 334. The lower ends of the connecting bolts 335 penetrate the clamping base plate 333 and extend to the lower end of the clamping base plate 333. In this embodiment, the sliding frame 331 and the guide strip 332 can cooperate with the guide assembly 32 to form a stable guiding effect. At the same time, the clamping base plate 333 and the clamping upper plate 334 can form a good clamping effect on the sheet metal to be conveyed, ensuring that the position of the stamped part will not be significantly different.

[0030] Working principle: The limiting plate 312 restricts the sliding tube 314 in the area of ​​sliding on the surface of the guide rod 311. The spring 315 assists the sliding tube 314 in driving the sliding assembly 33 to move longitudinally. The contact disc 313 moves synchronously with the sliding tube 314. The connecting rod 321 and the side guide plate 322 combine to form a guiding function. The support rib 323 strengthens the support of the sliding assembly 33 during movement. The guide groove 324 assists in guiding the sliding assembly 33, ensuring that the material conveying position does not change significantly and improving the material stamping effect. The sliding frame 331 and the guide bar 332 cooperate with the guide assembly 32 to form a stable guiding function. The clamping bottom plate 333 and the clamping top plate 334 form a good clamping function for the plate to be conveyed.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
