Description
Technical field
The invention belongs to technical field of forging and pressing equipment, especially relates to a kind of novel forging drift.
Background technology
Drift is for punching on press forging.Under normal circumstances, in order to ensure the intensity of drift, the length of drift is all shorter, but when the hole that working depth is larger, the scope of attack of drift and the upper surface of press forging concordant after, drift cannot hit down by steam hammer again, and this makes deep hole processing on press forging very difficult.If just do long by punch length at ordinary times, not only the intensity of drift reduces, and drift is easy to be rushed askew.In addition, the drift that overwhelming majority producer of China uses is integrated member, once surface abrasion is overproof, whole drift is just caused to be scrapped, particularly imported large-scale die casting machine punch, because size is comparatively large, material body is expensive, the discarded waste caused is comparatively large, often more renews drift and adds production cost.
Summary of the invention
The problem that the invention will solve is to provide a kind of novel forging drift, adopts fabricated structure, when needs deep hole processing, punch body can be extended, and change punch body convenient, cost is low.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: comprise punch holder and punch body; Described punch holder comprises the holder of upper end and the depression bar of lower end; Described punch body comprises the alloy-layer of inner core and inner core arranged outside; On described depression bar, symmetry is provided with two locating dowels; Described punch body upper end is provided with connection heavy stand, and on the sidewall of connection heavy stand, symmetry is provided with two groups of link slots; Described depression bar lower end is stretched into and is connected in heavy stand, and locating dowel is stuck on link slot, and described link slot comprises vertical groove and vertically and be communicated with several translots of vertical groove, and described locating dowel is placed in translot.
Further, described holder is provided with connecting hole.
Further, the length of described locating dowel is 2 ~ 5mm.
Further, the thickness of described alloy-layer is 1.5 ~ 3mm.
Further, the thickness of described sidewall is greater than 5mm.
Further, described inner core is cast iron or carbon steel.
The advantage that the invention has and good effect are:
1) adopt unique fabricated structure, when needs deep hole processing time, punch body can be extended.When punch body damages, it is convenient to change, and use cost is low.
2) locating dowel is fastened in link slot, and locating dowel does not protrude from the sidewall connecting heavy stand, connects reliable, for convenience detach.
3) inner core is common cast iron or carbon steel, arranged outside alloy steel layer, while guarantee drift intensity, effectively reduce cost.

Fig. 2 is the structural representation of adjusting seat in the invention;
Fig. 3 is the sectional view of punch body in the invention;
Fig. 4 is the structural representation of punch body in the invention.
Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
A kind of novel forging drift, as shown in Figure 1, Figure 2 and Figure 4, comprises punch holder 1 and punch body 2; Described punch holder 1 comprises the holder 3 of upper end and the depression bar 4 of lower end; As shown in Figure 3, described punch body 2 comprises the alloy-layer 6 of inner core 5 and inner core 5 arranged outside; Described depression bar 4 is along the circumferential direction gone up and symmetrical is provided with two locating dowels 41; Described punch body 2 upper end is provided with and connects heavy stand 7, along the circumferential direction symmetrically on the sidewall 8 connecting heavy stand 7 is provided with two groups of link slots 9.Described depression bar 4 lower end is stretched into and is connected in heavy stand 7, and locating dowel 41 is stuck on link slot 9.Adopt fabricated structure, when punch body 2 damages, it is convenient, cost-saving to change.
Described holder 3 is provided with connecting hole 31.By connecting hole 31, these forging and stamping drift is connected on forging equipment.
The length of described locating dowel 41 is 2 ~ 5mm.The thickness of described sidewall 8 is greater than 5mm.Described link slot 9 comprises vertical groove 91 with vertical and be communicated with several translots 92 of vertical groove 91.Locating dowel 41 is fastened in link slot 9, and locating dowel 41 does not protrude from the sidewall 8 connecting heavy stand 7, connects reliable, for convenience detach.
Described inner core 5 is cast iron or carbon steel.The thickness of described alloy-layer 6 is 1.5 ~ 3mm.Inner core 5 is common cast iron or carbon steel, arranged outside alloy steel layer, while guarantee punch body 2 intensity, effectively reduce cost.
In forging and stamping process, the punch holder 1 be connected on forging equipment drives punch body 2 to move down, and punch body 2 touches the moment of the workpiece of below, and the depression bar 4 of punch holder 1 lower end impacts to punch body 2, and punch body 2 pairs of workpiece are hit.
The wear-resisting alloy-layer due to punch body 2 arranged outside, not easy to wear, thus make drift average life span improve, in addition, punch body 2 be worn serious or damage time, only need replace with new punch body 2, it is convenient to change, and saves necessary overall maintenance cost of exchanging drift originally to greatest extent, decreases trouble and workload that staff exchanges drift, ensure that the normal table of die casting machine is produced, enhance productivity.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
