Sand core trimming device

Abstract

The invention discloses a sand core trimming device. The sand core trimming device comprises a machine frame, a portal frame, a left working table, a right working table and a protection frame are fixedly arranged at the top of the machine frame, the portal frame is fixed at the rear end of the top of the machine frame, a mounting block is arranged on the top of the portal frame in a sliding mode,a left pneumatic sliding table and a right pneumatic sliding table are arranged on the two sides of the front end of the mounting block respectively, the left pneumatic sliding table and the right pneumatic sliding table are respectively provided with a left main shaft and a right main shaft, the left pneumatic sliding table and the right pneumatic sliding table control the rise and fall of the left main shaft and the right main shaft respectively to achieve the switching of working states, the left working table and the right working table are located below the left main shaft and the rightmain shaft, a sand discharging groove is formed in the top of the machine frame between the left working table and the right working table, and a discharging hole is formed in the middle of the sand discharging groove. According to the device, the burrs of two sand cores can be trimmed at the same time, and different grinding heads can be installed according to requirements to deal with differenttypes of burrs.

Description

technical field [0001] The invention relates to the technical field of casting processing, in particular to a sand core trimming device. Background technique [0002] With the continuous development and renewal of casting technology, castings are becoming more and more complex. Due to the complexity of the internal shape and structure of castings, the sand cores that form the internal structure of castings are becoming more and more difficult to make. The original manual operation cannot effectively solve difficult sand cores. The problem of burrs, so integrated manipulators are used more and more, but the cost of integrated manipulators is high, the efficiency is average, and it takes up a lot of space, resulting in waste of cost and difficulty in trimming burrs. In view of this, it is necessary to improve the traditional sand core trimming equipment . Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invent...
