Abstract
The invention discloses a method for manufacturing ramming plates of a ramming machine and belongs to the technical field of mechanical manufacturing. The method comprises the following processing steps: (1) preparing materials of the ramming plates of a ramming machine; (2) forging the ramming plates of the ramming machine; (3) annealing the ramming plates of the ramming machine; (4) carrying out fine processing on the ramming plates of the ramming machine; (5) quenching the ramming plates of the ramming machine; and (6) tempering the ramming plates of the ramming machine. By the method, the problem that the service life of the ramming machine is affected due to not high strength and toughness of the ramming plates during the working of the existing ramming machine is solved and the method has the advantages of simplicity in process, low cost and easiness in processing.
Description
Technical field
The invention belongs to machinery manufacturing technology field, more particularly, relate to the processing of a kind of ramming machine tamping plate and heat-treating methods.
Background technology
In construction work, need to carry out sufficient compacting to foundation soil, to reduce the space between soil particle, increase its compaction rate, ensure the stability of ground, obtain enough supporting capacitys.Compacting for ground adopts ramming machine usually, and its principle of work utilizes weight at the potential energy of certain altitude, changes kinetic energy into impact by pressure layer, to make to be pressed the compaction rate of layer to be increased after falling.And in the course of the work, when the potential energy of eccentric block changes kinetic energy into impact by pressure layer, shock action being directly passed to by the component of pressure layer is tamping plate, therefore tamping plate serves the effect of transmitting surging force in whole process, it needs enough intensity and toughness, to ensure having good work-ing life.
Summary of the invention
For existing ramming machine in the course of the work, because of the intensity of tamping plate and toughness not high, and then affect the problem in its work-ing life, the invention provides a kind of manufacture method of ramming machine tamping plate, it is by reconfiguring ramming machine tamping plate material, and coordinate suitable thermal treatment process, its intensity and toughness are improved, reach the object improving its work-ing life.
For solving the problem, the present invention adopts following technical scheme.
A manufacture method for ramming machine tamping plate, comprises the following steps:

(2) forging of ramming machine tamping plate;
(3) anneal of ramming machine tamping plate:
Ramming machine tamping plate is heated to 650-750 DEG C, and the laggard sector-style of held for some time is cold;
(4) precision work of ramming machine tamping plate;
(5) quench treatment of ramming machine tamping plate:
Ramming machine tamping plate is heated to 820-850 DEG C, insulation 2
hafter carry out oil quenching;
(6) temper of ramming machine tamping plate:
Ramming machine tamping plate is heated to 450-500 DEG C and carries out tempering, tempering twice, the laggard line space of tempering is cold.
Preferably, in described step (1), the mass percent of ramming machine tamping plate material component is: C:0.90%, Cr:1.40%, Mn:1.35%, Si :≤0.60%, S :≤0.40%, and all the other are Fe.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention is by reconfiguring ramming machine tamping plate material, and coordinates suitable thermal treatment process, and its intensity and toughness are improved.
