Manual adjustment tapered wedge type closed die height adjusting device

Abstract

The invention discloses a manual adjustment tapered wedge type closed die height adjusting device. The manual adjustment tapered wedge type closed die height adjusting device comprises a rack assembly, a sliding block assembly, a connecting rod assembly, a tapered wedge assembly, an oil cylinder assembly, a transmission adjusting assembly and an auxiliary guide assembly. The sliding block assembly is mounted on the rack assembly through the connecting rod assembly, and the tapered wedge assembly is connected with the sliding block assembly through the oil cylinder assembly and the auxiliary guide assembly; the oil cylinder assembly, the auxiliary guide assembly and the transmission adjusting assembly are all connected to the sliding assembly; power drives the connecting rod assembly to move, and the connecting rod assembly further drives the sliding block assembly to do reciprocating operation along the assembling position of the rack assembly; and when the transmission adjusting assembly is affected by external force, the tapered wedge assembly is adjusted, and therefore the sliding block assembly, the oil cylinder assembly and the auxiliary guide assembly are adjusted, and finally, fine adjustment of die filling height can be achieved. Through cooperative use of an upper tapered wedge, a lower tapered wedge and a sliding block, the adjustment precision, stability and portability of the closed die height can be improved, and accurate die adjusting of different materials can be achieved.

Description

technical field [0001] The invention relates to the field of punching machines, in particular to a device for adjusting the height of a closed mold with manual adjustment of wedge blocks. Background technique [0002] According to the different adjustment methods, the press die height adjustment mechanism mainly includes eccentric worm wheel adjustment, eccentric pin adjustment, eccentric bearing sleeve adjustment, wedge-shaped table adjustment, etc. Different adjustment mechanisms are suitable for different working conditions. [0003] However, in recent years, the demand for plastic processing, powder forming, forming of difficult-to-form materials, forming of complex-shaped parts, composite forming of symmetrical linkages, and high-precision forming has become increasingly strong. When clearly seeing the broad development prospects of the press, higher requirements are put forward for the mold height adjustment mechanism of the press. However, in the prior art, the adjus...

Problems solved by technology

When clearly seeing the broad development prospects of the press, higher requirements are put forward for the height adjustment mechanism of the press. However, in the prior art, the adjustment accuracy of the closed mold height is not high, the stability is poor, and the most important The problem is that it is impossible to achieve accurate mold adjustment for different materials, and it is extremely inconvenient to use
