Cutting device for sprue gate of tubular casting

Abstract

The invention discloses a cutting device for a sprue gate of a tubular casting. The cutting device comprises a device main body, two groups of workpiece seats are riveted at the bottom of the device main body; a fixed hoop is welded to the upper end faces of the workpiece seats. A movable hoop is arranged above the fixed hoops; arc clamping sleeves are arranged in the middles of the inner side faces of the fixed hoop and the movable hoop correspondingly, a workpiece is placed between the two arc clamping sleeves, long screws are arranged on the two sides of the workpiece, moving grooves allowing the two sets of long screws to move are formed in the fixed hoop and the movable hoop correspondingly, and the upper ends of the long screws are sleeved in nuts. According to the cutting device forthe sprue gate of the tubular casting, a workpiece is clamped in the middle, and meanwhile, the two sets of the long screws can flexibly move to cater to workpieces with different sizes; the arc contact surfaces of the clamping sleeves are in contact with the workpiece, the fixed contact area is increased, and the friction force is increased, so that the fixing effect is improved, different working conditions are adapted, and better use prospects are brought.

Description

technical field [0001] The invention relates to the field of tubular casting processing, in particular to a cutting device for a sprue of a tubular casting. Background technique [0002] During the processing of castings, the smelted liquid metal needs to be injected into the pre-prepared mold by pouring, injection, suction or other casting methods. Before pouring, it is necessary to use a cutting device to open a number of pours on the mold Mouth; when cutting the opening of the current tubular castings, the cutting accuracy is affected because the castings are not easy to fix. At the same time, there are differences in the size of the castings each time, which increases the difficulty of fixing, and the waste generated during cutting cannot be collected in time, causing pollution. Inside the device, for this purpose, we propose a sprue cutting device for tubular castings. Contents of the invention [0003] The main purpose of the present invention is to provide a sprue ...
