Machine shell punching and burr trimming device

Abstract

The invention provides a machine shell punching and burr trimming device. A machine shell base is fixed to a base. A machine shell is installed on the machine shell base. An outer die is installed on the outer side of each position, where a hole is to be machined, on the machine shell, and a burr trimming tool rest is installed on the inner side of each position, where a hole is to be machined, on the machine shell. The outer dies and outer die bases are movably connected. The outer die bases are fixed to the base. The burr trimming tool rests are movably connected with a support. During work, an upper base moves downwards, thrust acting faces of thrust mechanisms act on the stress faces of the outer dies, punching cutters act on the machine shell to form the holes, waste materials obtained through punching are discharged through discharge holes and discharge channels, the upper base continues to move downwards, a straight stamping rod acts on tool rest stress faces, the burr trimming tool rests move to the two sides, and burr trimming of the inner side faces of the holes is completed. The work is completed, the upper base moves upwards, the thrust mechanisms contact under the effect of oil cylinders, and the thrust mechanisms are prevented from colliding with the outer dies. Various types of combined movement is adopted, the punching and burr trimming of the machine shell are completed at one station through one-time stamping, the machining precision of products is improved, and meanwhile the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a stamping device, in particular to a casing punching and deburring device. Background technique [0002] At present, due to the low cost of stamping products, as the application of punching machines is becoming more and more popular at home and abroad, and the precision of stamping is improved, many products are produced by stamping by punching machines, and many workpieces with complex shapes are also produced by stamping. Invented casing punching and deburring, how to punch a certain number of holes on the shell of the casing, and how to deburr the inner side of the holes. In the past, after punching, manual deburring was used, so the processing efficiency of the product was not high, and the quality of deburring was not good. [0003] The casing punching and deburring device mentioned in the present invention makes the punching and deburring of the casing at one station through multiple combined movements, and is completed...
