Abstract
The utility model relates to a welding/gas-quenching integrated stove used for a lengthened cutter. A welding bin and a quick-cooling bin are fixedly installed on a stove frame in a coaxial mode, an engine driven lifting door is arranged on the quick-cooling bin and positioned between the welding bin and the quick-cooling bin, a conveying belt is arranged on the welding bin and the quick-cooling bin and used for communication the welding bin and the quick-cooling bin, a welding machine is installed on the side of the conveying belt in the welding bin, and a nitrogen nozzle is installed in a welding cover of the welding machine. According to the integrated stove, welding and heat treatment of the cutter are completed on one device, technical processes are simplified, energy is saved, the welding/gas-quenching integrated stove used for the lengthened cutter is an energy-saving and environment-friendly device, wherein a brazing technology is used for the welding, a quick gas-quenching technology is used for the heat treatment, the cutter with waste heat after welding directly enters the quick-cooling bin, the nitrogen nozzle arranged in the quick-cooling bin ejects nitrogen to the cutter, the temperature of the cutter instantaneously drops below room temperature form welding temperature, and therefore the purpose of quenching is achieved. Due to the fact that the medium for quenching is nitrogen, the cutter after the quenching is bright on surface and relatively high in hardness and intensity, and the metallographical quality of the lengthened cutter is effectively improved.
Description
Technical field
The utility model belongs to welding field, relates to the welding that lengthens cutter, and especially a kind of lengthening cutter is with the welding/gas all-in-one oven of quenching.
Background technology
Along with the develop rapidly of economy, China's all trades and professions have all entered the free way of development.Especially the equipment manufacture of China has obtained fast development especially.But nearly all run into bottleneck in development.As in mechanical processing industry, indispensable lengthening cutter more than two meters has just run into such problem.Because welding and heat treatment technics do not pass a test, have a greatly reduced quality service life, and according to incomplete data statistics, China cutter life hangs down 30% than the life-span of the cutter that the developed countries such as Japan and Germany produce.
Traditional cutter production technology is after blade, solder and cutter hub are assembled, put into coke-fired furnace heating welding, after visual solder fusing, cutter is taken out in coke-fired furnace, press on forcing press, purpose is with blade and cutter hub compacting and orthopedic, then is placed on the electric fan canyon and lowers the temperature to reach heat treated purpose.This mode makes cutter undesirable on physical property, causes thus service life and result of use relatively poor.
For this reason, research lengthens the new technology of cutter to improve service life, is very necessary.
The utility model content
The purpose of this utility model is to overcome the prior art deficiency, provides a kind of Welding of cutters and integrated lengthening cutter of heat treatment of lengthening with the welding/gas all-in-one oven of quenching.
The technical solution adopted in the utility model is:
A kind of lengthening cutter is characterized in that with the welding/gas all-in-one oven of quenching: coaxial welding chamber and the fast cold storehouse of being fixed with on grate, a motor-driven lift slide door is installed on the fast cold storehouse between welding chamber and fast cold storehouse, and welding chamber and fast cold storehouse are communicated with conveyer belt are installed; Conveyer belt side in welding chamber is equipped with a bonding machine, and the nitrogen nozzle is installed in the welding enclosure of this bonding machine.
And described motor-driven lift slide door adopts air motor.
Advantage of the present utility model and good effect are:
1, this all-in-one oven is the welding of cutter and heat treatment to be placed on an equipment complete, simplification of flowsheet and saved the energy, belong to energy saving and environment friendly equipment, wherein welding is to adopt soldering processes, heat treatment is adopted is the quick air technique of quenching, cutter after welding directly enters snap-chill cabinet with the waste heat of welding, the nitrogen nozzle that is arranged in snap-chill cabinet sprays nitrogen on cutter, cutter moment is down to below room temperature by welding temperature, thereby reach the purpose of quenching, because the medium that quenches is nitrogen, cutter is at quenching rear surface light, hardness and intensity are higher, effectively improved the metallographic quality that lengthens cutter.
2, this all-in-one oven technique is simple, and design science is rational in infrastructure, lengthen cutter the heat treatment utilization be the waste heat of welding temperature, saved thus mass energy.
Description of drawings:
Fig. 1 is structural front view of the present utility model.
The specific embodiment:
The utility model is described in further detail in conjunction with specific embodiments below by accompanying drawing, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of lengthening cutter is with the welding/gas all-in-one oven of quenching, and a motor-driven lift slide door 6 is installed in coaxial welding chamber 2 and the fast cold storehouse 8 of being fixed with on grate 1 on the fast cold storehouse between welding chamber and fast cold storehouse, and welding chamber and fast cold storehouse are communicated with conveyer belt 3 is installed.
Conveyer belt side in described welding chamber is equipped with a bonding machine 4, and this bonding machine lengthens cutter and complete welding in welding chamber.Nitrogen nozzle 5 is installed in the welding enclosure of this bonding machine, and this nitrogen has been the protection Welding of cutters and has guaranteed carbon potential.Lengthening cutter after welding is before conveyer belt is delivered to the motor-driven lift slide door in fast cold storehouse.
The cold storehouse of described speed arranged outside has refrigeration unit, and this refrigeration unit forms the low temperature of-5 ℃-0 ℃ in speed cold storehouse, makes thus through lengthening cutter that conveyer belt sends to quench in speed cold storehouse.Lengthening cutter after process is quenched is outside conveyer belt is sent fast cold storehouse.
Described motor-driven lift slide door adopts air motor 7 to carry out, and promotes and closing velocity to improve.
Claims (2)
1. a lengthening cutter with the welding/gas all-in-one oven of quenching, is characterized in that: coaxial welding chamber and the fast cold storehouse of being fixed with on grate, a motor-driven lift slide door is installed on the fast cold storehouse between welding chamber and fast cold storehouse, and welding chamber and fast cold storehouse are communicated with conveyer belt are installed; Conveyer belt side in welding chamber is equipped with a bonding machine, and the nitrogen nozzle is installed in the welding enclosure of this bonding machine.
2. lengthening cutter according to claim 1 is with the welding/gas all-in-one oven of quenching, and it is characterized in that: described motor-driven lift slide door adopts air motor.
