Pan hanging device for salt bath nitrogen treatment on casting iron pan

Abstract

The invention relates to a pan hanging device for salt bath nitrogen treatment on a casting iron pan. The pan hanging device comprises a pan hanging bracket, bolts, nuts and round holes, wherein the pan hanging bracket comprises a base, supporting pillars and a plurality of hanging rings; the hanging rings and the base are all provided with supporting beams; five supporting pillars are vertically welded on the supporting beams of the base; the hanging rings are fixed at intervals on the supporting pillars from top to bottom through the supporting beams; the round holes are formed in the hanging rings; the bolts penetrate through the round holes from top to bottom; the ends, penetrating through the round holes, of the bolts are fastened on the hanging rings through the nuts. As the supporting beams are arranged on the hanging rings and the base, and the five hanging pillars are vertically welded on the supporting beams of the base to fasten the whole pan hanging bracket, the pan hanging device is difficult to twist and deform during transfer; meanwhile, the fastening manner that the bolts and the nuts penetrate through the round holes in the hanging rings from top to bottom increases strength of the pan hanging device, so that the condition that the production schedule is influenced because steel wires are broken during previous connection is avoided, the arranging manner of the bolts ensures that the nuts are still hung on the hanging rings after being dismounted, and the pan hanging device is time-saving and labor-saving.

Description

technical field [0001] The invention relates to the technical field of metal salt bath nitriding treatment equipment, in particular to a hanging pot device for salt bath nitriding treatment of cast iron pans. Background technique [0002] In recent years, for cast iron pan blanks, fatigue resistance, wear resistance, high strength and aesthetics are the basic requirements for the metal surface. The existing surface treatment of metal parts is mainly salt bath nitriding treatment method. [0003] Salt bath nitriding treatment of cast iron pots The general method of hanging the pot is to use a pin with a round hole, first use the pin to put the untreated cast iron pot blank on the simple hanging pot support, and then use the steel wire to pass through the round hole of the pin. It is time-consuming and labor-intensive to wear the pins every time the cast iron pan is put on and off the shelf, and reduces the production efficiency. When the steel wire fixing the pin breaks, the...

Problems solved by technology

[0004] In order to solve the problem that when the steel wire of the fixing pin breaks, the pot billet is easy to fall into the salt bath furnace, and it is difficult to remove it, which affects the production progress. The simple hanging pot bracket cannot bear too much weight because of the unstable structure between the parts, which limits each The processing quantity of the cast iron pan during salt bath nitriding affects the production progress, and when the cast iron pan is overweight, it is prone to distortion and deformation. The purpose of this invention is to propose a hanging device for cast iron pan salt bath nitriding treatment , this device replaces the pins and steel wires that fix the pan blanks with bolts and nuts, and at the same time reinforces the overall pan hanging bracket, so as to avoid the pan blank falling into the salt bath furnace and the pan hanging bracket being overstressed due to broken steel wires The situation that greatly causes distortion and deformation and affects the production schedule
