Abstract
Disclosed is quenching equipment for caterpillar track, which comprises a roller hearth quenching heating furnace, an automatic distributing mechanism, a pneumatic double-work-station force quenching machine with and a roller hearth backfire heating furnace. Wherein, the roller hearth quenching heating furnace and the automatic distributing mechanism are arranged in front of the pneumatic double-work-station force quenching machine, and the roller hearth backfire heating furnace is arranged behind the pneumatic double-work-station force quenching machine. The pneumatic double-work-station force quenching machine comprises two sets of upper pressure difference spraying devices, an upper oppressing positioning device, a lower oppressing positioning device and a lower pressure difference spraying device. Compared with single work station, the production efficiency is improved by one time. The utility model uses forced quenching. When the workpiece enters the pneumatic double-work-station force quenching machine, the workpiece is given a 3 to 6 ton pressure. With quenching under pressure, the misshaping occurrence is decreased, so that the labor intensity is decreased and the production efficiency is improved. With a roller hearth quenching and backfire heating furnace in the utility model, the workpieces are heated equally without abrasion and distortion and with stable transmission and stable product quality.
Description
Technical field:
The utility model relates to mechanical quenching device, relates in particular to the quenching device of dozer, excavator usefulness grip-pad.
Background technology:
Workpiece after heat treatment all may produce distortion, mainly be that reasons such as thermal stresses, structural stress and workpiece features of shape cause distortion, wherein serious with quenching strain, often bigger in the production because of the quenching strain amount, need expend a large amount of man-hours and proofread and correct or repair, even owing to overproof the scrapping of distortion.Therefore, manage to control and reduce the important content that the workpiece quenching strain is thermal treatment work, the method for control workpiece quenching strain has many, as heat-processed control, forces quenching, process of cooling control etc.Dozer, excavator grip-pad, workpiece is big, wall is thin, and the cross section is asymmetric, quenching easily produces distortion, and factory adopts the discontinuous running furnace apparatus to carry out the quenching of grip-pad mostly at present, and labor strength is big, the product distortion is big, of poor quality, need proofread and correct or repair after the thermal treatment, production efficiency is low.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of grip-pad quenching device is provided, and can effectively solve the problem of grip-pad quenching strain.
Grip-pad quenching device described in the utility model, include roller bottom type quenching process furnace, automatic placement material mechanism, pneumatic quenching machine and the roller bottom type tempering process furnace composition of forcing of double, the pneumatic quenching machine that forces of said double is the main part of grip-pad quenching device described in the utility model, is made up of two pneumatic quenching machines that force arranged side by side.The pneumatic quenching machine that forces of said double disposes counterweight and descaling mechanism.Be provided with roller bottom type quenching process furnace and automatic placement material mechanism before forcing quenching machine in that double is pneumatic, be provided with roller bottom type tempering process furnace after forcing quenching machine in that double is pneumatic.Said double is pneumatic force quenching machine include two put the pressure reduction waterworks, on oppress locating device, lower compression locating device and following pressure reduction waterworks and form, compare with single station, can enhance productivity nearly one times.
Grip-pad quenching device described in the utility model, the device that provide a kind of grip-pad heating, quenches, the technical measures of taking are: 1, for solving in the workpiece quenching heat-processed, inhomogeneous and the problem of damaging, in conjunction with the grip-pad features of shape, the utility model has been selected roller bottom type quenching process furnace, and roller hearth furnace is to be provided with the many laterally rollers of rotation at straight-through burner hearth bottom, drives the furnace charge that is placed on the roller and moves along roller-way.Furnace charge moves in heat-processed continuously, does not have the fixed point of contact with roller-way, so homogeneous heating, nothing damage, be out of shape little, and overcome the deficiency of primitive period quenching furnance charging mode: workpiece is stacked, and heats the irregular and problem of damaging.2, for solving the quenching strain problem, the utility model has adopted the quenching mode of forcing, workpiece enters that double is pneumatic force quenching machine after, workpiece is applied the pressure of 3～6T, under pressure state, quench, can significantly reduce workpiece deformation.3, according to the track plate structure characteristics: the above and below is asymmetric, causes the inconsistent problem on deformation that causes of cooling rate.The utility model is regulated the above and below cooling rate by adjusting top and bottom water spray pressure reduction respectively, and it is consistent that both cooling rates are realized, reaches the purpose of control grip-pad quenching strain.4, for reducing labor strength, boost productivity, adopt automatic production.
The technical scheme that its technical problem that solves the utility model adopts is: adopted roller bottom type Q-tempering process furnace, workpiece homogeneous heating, nothing are damaged, are out of shape little, and stable drive realizes automatization, reduces human factor; Quench and adopt pressure spacing, force quenching, cooperate the pressure reduction of spraying water up and down, reach the purpose of control quenching strain.
The beneficial effects of the utility model are, the level of automation height, and constant product quality, simple in structure.
