Description

Circuit breaker and method and equipment for automatically assembling contact and copper sheet of circuit breaker

Technical Field

The invention relates to the technical field of circuit breaker production, in particular to automatic assembling equipment for a contact and a copper sheet of a circuit breaker.

Background

The circuit breaker is a switching device capable of closing, carrying, and opening/closing a current under a normal circuit condition and a current under an abnormal circuit condition within a prescribed time. A circuit breaker generally includes a contact system, an arc extinguishing system, an operating mechanism, a trip unit, a case, and the like. The contact is an electric contact material used for switches, relays, electric connection and electric plug elements, is also called as an electric contact material and is generally divided into two types, namely a strong electric contact material and a weak electric contact material. The contact material should have suitable hardness, and less hardness can increase the contact area under certain contact pressure, reduce contact resistance, reduce contact heating and static fusion welding tendency during static contact, and can reduce moving contact bounce during closing. Higher hardness can reduce the weld area and improve the mechanical wear resistance. The contact material should have a suitable elastic modulus. Higher elastic modulus is easy to reach the limit value of plastic deformation, so the surface film is easy to break, which is beneficial to reducing the resistance of the surface film, and lower elastic deformation can increase the contact area of elastic deformation. The contact material should have a high electrical conductivity to reduce contact resistance, low secondary emission and light emission to reduce arc current and arcing time. The contact material should have a high thermal conductivity so that heat generated by the arc or joule heat source is transferred to the contact base as quickly as possible. High specific heat capacity, high latent heat of fusion, vaporization and decomposition. High ignition and boiling points to reduce the tendency to arcing. The low vapor pressure limits the metal vapor density in the arc.

Contact subassembly mainly has three kinds of forms, and one is traditional riveting type, with rivet type contact riveting on five metals terminal: the other is welding type, the sheet contact is welded on a hardware terminal or a bimetallic strip; and thirdly, stamping parts, namely stamping the silver-copper composite belt into required components. Need decide the copper sheet area in the contact subassembly welding process of welding type, will decide the copper sheet equipment welding to the contact again, present equipment has following several problems in the course of working: the deburring method comprises the following steps that (A) before a copper sheet is welded on a contact, the contact needs to be deburred, the two ends of the contact are clamped by a clamping cylinder in the deburring process through the existing equipment, and then deburring is carried out through a deburring cutter, so that clamping force is inconvenient to control in the clamping process, indentation appears on the contact due to too high force, and looseness appears in the deburring process due to too low recovery force, so that burrs cannot be completely removed; the existing equipment directly conveys the contact subjected to deburring to the position where the contact is assembled with the copper sheet through a conveyor belt for assembly processing, so that the conveyor belt only conveys the contact, the equipment space is wasted, and the processing efficiency is reduced; the existing equipment does not have a coating link between the deburring process and the assembly of the copper sheet, so that the position of the copper sheet is easy to change in the welding process after the copper sheet and the contact are assembled, the welding precision of the copper sheet and the contact is low, and the rejection rate of products is improved; and (IV) in the process of cutting the copper sheets one by one, only one end of each copper sheet is fixed and clamped, and the copper sheets cannot be clamped and positioned well, so that the other end of each copper sheet is loosened in the cutting process, the shape of the cut copper sheet is incomplete, and the cutting quality and the overall product quality of the copper sheet are reduced.
