Abstract
The invention discloses a method for manufacturing a pin bush of a bulldozer track. The method comprises the following steps of: (1) blanking: intersecting a bar; (2) upsetting, reversely squeezing and punching; (3) annealing: cooling at normal temperature; (4) performing ball-throwing treatment; (5) roughly turning the shape; (6) integrally quenching and tempering; (7) carburizing; and (8) finely turning the outer circle and the end face. In the method, the utilization rate of raw materials is high and the production cost is low. As the raw materials are reheated and reannealed, inner stress of the raw materials is eliminated; furthermore, the grade of the particle size of the pin bush is increased; therefore, by the method, the structural performance of the pin bush can be improved and the service life of the pin bush can be prolonged.
Description
Technical field
The present invention relates to a kind of preparation method of guide, especially a kind of preparation method of bull-dozer crawler belt guide.
Background technology
The method of producing now bull-dozer crawler belt guide is quench tempering, carburizing, finish turning cylindrical and an end face of directly rough turn by steel pipe, cylindrical, because steel pipe price height causes the cost of manufacture of crawler belt guide higher, the whole cost of track rail assembly is higher.
Summary of the invention
The preparation method that the purpose of this invention is to provide a kind of bull-dozer crawler belt guide solves the raw material steel pipe high shortcoming of guide cost that causes on the high side in the prior art, can improve steel utilization ratio, working (machining) efficiency, raising structural behaviour, prolongs its service life.
The objective of the invention is to adopt following steps to realize:
(1) blanking, the intercepting bar;
(2) jumping-up, oppositely extruding, punching are heated to temperature 900-1000 ℃ with bar, the open die forging jumping-up, then in extrusion die, blank is oppositely pushed, make and be formed centrally the round barrel shape endoporus in the blank, in punching die, wash away an end endoporus gross weight again, form steel pipe;
(3) annealing, the normal temperature cooling;
(4) Shot Blasting;
(5) rough turn profile is located rough turn endoporus with cylindrical earlier, locatees rough turn cylindrical and end face with endoporus again;
(6) integral quenching tempering;
(7) carburizing;
(8) finish turning cylindrical and end face.
Utilization rate of raw materials height of the present invention, production cost is low.Because raw material are through heating once more and annealing, eliminated the raw material internal stress, and the guide grain size number increases, so the present invention can improve the structural behaviour of guide, increase the service life.
The specific embodiment
This bull-dozer crawler belt guide adopts following steps to realize:
(1) blanking, the intercepting bar;
(2) jumping-up, oppositely extruding, punching are heated to temperature 900-1000 ℃ with bar, the open die forging jumping-up, then in extrusion die, blank is oppositely pushed, make and be formed centrally the round barrel shape endoporus in the blank, in punching die, wash away an end endoporus gross weight again, form steel pipe;
(3) annealing, the normal temperature cooling;
(4) Shot Blasting;
(5) rough turn profile is located rough turn endoporus with cylindrical earlier, locatees rough turn cylindrical and end face with endoporus again;
(6) integral quenching tempering;
(7) carburizing;
(8) finish turning cylindrical and end face.
Claims (1)
