Large-size frame type roll-over machine

Abstract

The invention relates to a large-size frame type roll-over machine. The large-size frame type roll-over machine comprises an upper transverse beam, a suspension arm and overturning frames. The large-size frame type roll-over machine is characterized in that a rack oil cylinder is mounted at the lower end of the suspension arm; a gear shaft of the rack oil cylinder is connected with the overturning frames; profile steel inner cavities of the overturning frames are provided with a first synchronizing shaft, a second synchronizing shaft, a first clamping oil cylinder and a second clamping oil cylinder; two clamping plates are arranged between the overturning frames; the first synchronizing shaft and the second synchronizing shaft are parallel to each other; the first clamping oil cylinder and the second clamping oil cylinder are parallel to each other; a first synchronizing chain is wound on a chain wheel at one end of the first synchronizing shaft and a chain wheel at one end of the second synchronizing shaft; a second synchronizing chain is wound on a chain wheel at the other end of the first synchronizing shaft and a chain wheel at the other end of the second synchronizing shaft; front and rear trunnions of the first clamping oil cylinder and the second clamping oil cylinder are connected with the clamping plates; the front and rear trunnions of the first clamping oil cylinder are connected with the two ends of the first synchronizing chain; the front and rear trunnions of the second clamping oil cylinder are connected with the two ends of the second synchronizing chain. The large-size frame type roll-over machine is suitable for various sand moulds and is convenient and reliable to use.

Description

technical field [0001] The invention relates to a large-scale frame-type mold turning machine, in particular to an equipment suitable for turning, flow-coating and mold-fitting medium and large sand molds in a foundry after boxless molding. Background technique [0002] In casting production, boxless molding is widely used because of less tooling, but medium and large sand molds cannot be hoisted, hung, and turned over, which has become a problem. There is no ideal utensil up to now, and the development of a suitable turning machine has become the focus of attention of many foundry enterprises and foundry workers. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies in the prior art and provide a large-scale frame-type turning machine. [0004] According to the technical solution provided by the present invention, the large-scale frame-type turning machine includes a gantry hanger and an overturning frame arranged under the gantr...
