Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, and more specifically to a B-pillar inner plate stamping device capable of reducing a roughening effect. Background Art

[0002] The stamping process is a process that separates or forms sheet metal to obtain a product. Stamping is a metal processing method that is based on the plastic deformation of metal. It uses molds and stamping equipment to apply pressure to the sheet metal to cause plastic deformation or separation of the sheet metal, thereby obtaining parts (stampings) with a certain shape, size and performance.

[0003] In the stamping production process, the burrs and marks on the sheet metal not only affect the quality of the stamping parts, but also affect the production efficiency, and have a certain impact on the service life of the mold. To solve the burr problem in the stamping part production process, the cause of the burr should be found. In the stamping process of the inner plate of the B-pillar, when there is foreign matter between the sheet metal and the mold surface, during the sheet metal stamping process, the foreign matter will slide on the surface of the sheet metal and cause burrs, and the forming surface of the mold will also have pits, affecting the quality of the inner plate of the B-pillar and the mold. The existing methods to reduce this kind of burr phenomenon are: first, before the stamping process, ensure the cleanliness of the sheet metal surface; second, use an air gun to sweep the inside of the concave surface of the mother mold before stamping to ensure the cleanliness of the mold and reduce the burrs. For the use of air gun sweeping, since the mother mold is usually fixed and installed with the concave surface facing up, when the air gun is used to sweep the foreign matter, it is difficult to quickly and smoothly discharge the foreign matter from the inside of the concave surface of the mother mold, and there is a defect of difficulty in sweeping, which reduces the efficiency of the overall stamping process.

The upper surfaces of the two conversion tables 8 are rotatably connected with a flip shaft 9, a stamping die 10 is fixedly installed on the surface of the flip shaft 9, and a flip assembly is arranged between the conversion table 8 and the flip shaft 9.

[0028] The processing table 1 is provided with a stamping station and a cleaning station corresponding to the two stamping dies 10 , respectively. The stamping punch 6 corresponds to the position of the stamping die 10 located at the stamping station.

[0029] When the present invention is in use, the whole device is connected to the external power control system in advance, and then the sheet material of the B-pillar inner panel after cleaning is placed in the inside of the stamping die 10, and the corresponding stamping die 10 is transferred to the stamping station, and the stamping punch 6 is driven down by the hydraulic telescopic rod 4 to close the mold with the stamping die 10, so as to achieve the purpose of stamping the B-pillar inner panel.

[0030] A vertical slide bar 21 is fixedly mounted on the top of the lifting plate 5 , and the vertical slide bar 21 is slidably connected to the surface of the top frame 5 .

[0042] Furthermore, when cleaning the surface of the stamping die 10, the stamping die 10 can be flipped by rotating it with the turning shaft 9 and the conversion table 8 so that the concave surface of the stamping die 10 faces downward. At this time, the crankshaft 23 is driven to rotate by the driving motor 22, and the vibration plate 13 is driven to vibrate under the transmission action of the transmission rod 24 and the pull rod 25. The inner wall of the stamping die 10 can be brushed by the bristles 14, and the air pump 16 blows the air flow to the concave surface of the stamping die 10 through the air outlet 15, so as to flush and sweep the inner wall of the stamping die 10, thereby ensuring the cleanliness of the inner concave surface of the stamping die 10, thereby achieving the purpose of reducing the roughening effect.
