Abstract
The invention relates to a press machine punch producing method. The method includes the steps of Step one, machining a punch body internally provided with a form cavity with medium carbon steel serving as a base; Step two, smelting high-carbon ferrochrome, molybdenum, copper and scrap steel, subjecting Cr, C and Mo components to optimization control during smelting and performing intensified smelting; Step three, producing a solution obtained in Step two into an alloy ingot according to the form cavity in the punch body; Step four, placing the alloy ingot heated to a temperature value into the form cavity of the punch body and simultaneously filling liquid steel into the form cavity to enable the liquid steel to be fused with the alloy block and the punch body interface. By means of the press machine punch producing method, a produced press machine punch has good impact toughness, avoids breaking during working, provides a guarantee for safe production, is high in hardness, has good wear resistance, prolongs the service life, accordingly reduces the production and use costs and improves production efficiency.
Description
Technical field
The present invention relates to a kind of processing method, be specifically related to a kind of processing method of press ram.
Background technology
Forcing press carries out punching press by drift to workpiece, the existing drift for forcing press becomes one, it is for adding man-hour to workpiece, damaging largely easily appears in the position of drift and absorption surface, because drift becomes one, its local damage is scrapped with regard to entirety, and generally adopts steel alloy for the drift of punching press, cost is higher, once scrap the raising that will cause production cost.
Summary of the invention
The present invention seeks to the processing method that a kind of press ram is provided to overcome the deficiencies in the prior art, by this processing method can obtain there is higher toughness and also hardness high, avoid the excessive press ram causing drift to damage of impulse force.
For achieving the above object, the technical solution used in the present invention is: a kind of processing method of press ram, step one, take medium carbon steel as the drift body that matrix processes the tangible chamber of its inner band; Step 2, adopts high carbon ferro-chrome, molybdenum, copper, steel scrap to carry out melting, in fusion process, is optimized control to Cr, C, Mo composition, implement intensified smelting; Step 3, is processed into alloy block according to the intrinsic shape chamber of drift by the solution of step 2; Step 4, when alloy block is heated to a temperature value, is inserted in this bodily form of drift chamber, meanwhile in this shape chamber, is injected molten steel, and molten steel and alloy block, this body interface of drift are fused.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The processing method of a kind of press ram of the present invention program, the press ram that can be obtained by this processing method not only has good impact flexibility, in the course of the work, drift can not rupture, and provides guarantee to safety in production, and its hardness is high, there is good anti-wear performance, improve the service life of drift, thus reduce manufacture and usage cost, improve production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation being obtained press ram by the processing method of a kind of press ram of the present invention;
Wherein: 1, drift body; 2, drift shell; 3, clamping platform; 4, hard alloy blocks; 5, urethane pad.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
A processing method for press ram, step one take medium carbon steel as the drift body 1 that matrix processes the tangible chamber of its inner band; Step 2, adopts high carbon ferro-chrome, molybdenum, copper, steel scrap to carry out melting, in fusion process, is optimized control to Cr, C, Mo composition, implement intensified smelting; Step 3, is processed into hard alloy blocks 4 according to the shape chamber in drift body 1 by the solution of step 2; Step 4, when hard alloy blocks 4 is heated to a temperature value, is inserted in drift body 1 shape chamber, meanwhile in this shape chamber, is injected molten steel, and molten steel and alloy block, this body interface of drift are fused.The press ram for adopting processing method of the present invention obtained as shown in Figure 1, this press ram comprises the drift shell 2 of drift body 1 and fixing drift body 1, described drift body 1 upper end is provided with clamping platform 3, described drift body 1 adopts carbon steel to be matrix, is interval with many group hard alloy blocks 4 in the matrix of described drift body 1; Between described clamping platform 3 and drift shell 2 inwall, be provided with urethane pad 5, play the effect of punching press buffering; Described hard alloy blocks material is 4Cr22MoCu.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
Claims (1)
1. for processing a processing method for a kind of press ram according to claim 1, it is characterized in that: step one, take medium carbon steel as the drift body that matrix processes the tangible chamber of its inner band; Step 2, adopts high carbon ferro-chrome, molybdenum, copper, steel scrap to carry out melting, in fusion process, is optimized control to Cr, C, Mo composition, implement intensified smelting; Step 3, is processed into alloy block according to the intrinsic shape chamber of drift by the solution of step 2; Step 4, when alloy block is heated to a temperature value, is inserted in this bodily form of drift chamber, meanwhile in this shape chamber, is injected molten steel, and molten steel and alloy block, this body interface of drift are fused.
