Overturning conveying structure for triangular magnesium pipe sintering equipment

Abstract

The invention provides an overturning conveying structure for triangular magnesium pipe sintering equipment. A humid triangular magnesium pipe with an inverted triangular section extruded and formed by an extruding machine is cut into segment-shaped triangular magnesium pipes by a cut-off machine, and air cylinders on sliding seats of conveying devices on two sides drive conveying clamps through telescopic rods to simultaneously move from the two sides to the center to clamp the segment-shaped triangular magnesium pipes. Power mechanisms drive the sliding seats on the two sides to synchronously perform linear motion along a guide rail to convey the segment-shaped triangular magnesium pipes to a drying machine, and the power mechanisms drive the air cylinders to rotate 180 degrees around the axis in the linear motion process at the same time, so that the segment-shaped triangular magnesium pipes with the inverted triangular section are overturned to be with a regular triangle section, and the segment-shaped triangular magnesium pipes can be smoothly discharged and placed horizontally through the bottom surface of the regular triangle and is convenient to convey to the next procedurefor orderly arranging, drying and burning. Conveying clamps can adapt to the section shape of the segment-shaped triangular magnesium pipes, flexible pads cannot scratch and damage the surfaces of the unfixed and shaped segment-shaped triangular magnesium pipes, the supporting and clamping effect is good, and conveying is smooth and reliable.

[0002] The electric heating tube of the electric heater is generally composed of a spiral resistance wire built into the metal tube, and crystalline magnesium oxide powder is filled between the resistance wire and the metal tube. The magnesium powder forms an insulating structure between the heating wire and the tube wall, and has outstanding The heat conduction function; after the traditional electric heating tube is directly filled with granular magnesium powder, the internal gap of the magnesium powder is squeezed by shrinking the tube, the compression density of the magnesium powder is increased, and its thermal conductivity and insulation performance are improved, but the inside of the electric heating tube is squeezed by the shrinking tube Magnesium powder in pure granular state, the compression effect is not good, the magnesium powder cannot be completely squeezed and compacted, and the shrinkage rate is low. A triangular magnesium tube is set between the inner wall of the metal tube and the resistance wire to provide fixed support for the resistance wire. The triangular magnesium The tube needs to be sintered by sintering equipment. Before sintering, it must be extruded by an extruder, cut off and dried, and then sintered. In order to facilitate cutting, the triangular magnesium tube extruded by the extruder is inverted with the tip facing down Triangular output, when transferred to the dryer for drying, it needs to be turned to a regular triangle with the tip facing upwards, so that it can be placed horizontally through the lower side of the regular triangle and arranged neatly to improve space utilization. The transfer fixture of the traditional continuous production line cannot adapt to the triangle. Magnesium tube transportation requires turning over, and it is easy to damage the unfixed wet triangular magnesium tube
