Abstract
The invention discloses a cold punching dual-stripping mechanism. The cold punching dual-stripping mechanism comprises a punch fixing plate, a punching discharging crossbeam, punches and a concave punching die. One end of each punch is fixedly mounted on the punch fixing plate, the lower end of the concave punching die is positioned on a lower die base plate, the punching discharging crossbeam is fixedly mounted at the upper end of the concave punching die and provided with through holes allowing the punches to penetrate through, a discharging rubber pad is arranged between the punch fixing plate and the concave punching die and provided with through holes allowing the punches to penetrate through. The punches are wrapped by buffering materials, and the discharging rubber pad is higher than the punches to make it convenient for discharging. In addition, since the buffering materials are added to a portion, contacting with a forged piece body, of the stripping mechanism, discharging and replacement are facilitated.
Description
technical field:
The invention belongs to stamping technology field, especially relate to the dual material removing mechanism in a kind of cold punching hole.
background technology:
General punching forgings adopts heat punching and cold punching two kinds of techniques, and the shortcoming of hot piercing is to make forging distortion or punch size be not easy to control.The advantages such as there is the uniformity that can ensure punch size in cold punching hole, not yielding.But steel are high in room temperature state lower yield point, bad de-material after hole punch, common practices adopts the method installing material removing mechanism on mould additional, but shortcoming easy scratch forging body.
summary of the invention:
Technical problem to be solved by this invention is: in punching forgings discharging, produce excessive power with material removing mechanism, need the power that device unloading is certain, and increase discharging buffering device on material removing mechanism, reach the effect not damaging forging body.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: the dual material removing mechanism in a kind of cold punching hole, described dual material removing mechanism comprises punch fixing plate, punching discharging crossbeam, drift and punching concave die composition, described drift one end is fixedly mounted on punch fixing plate, described punching concave die lower end is placed on bed die backing plate, described punching discharging crossbeam is fixedly mounted on punching concave die upper end, punching discharging crossbeam is provided with the through hole passed for drift, discharging rubber blanket is provided with between described punch fixing plate and punching concave die, described discharging rubber blanket offers the through hole passed for drift.
As preferably, the height of described discharging rubber blanket is greater than the length of drift body.
As preferably, the diameter of the through hole that described discharging rubber blanket is offered is less than the diameter of drift.
Compared with prior art, usefulness of the present invention is: the material that can cushion at the upper parcel of pierce punch, highly exceedes drift body, easy-unloading, add padded coaming in the place of de-material and forging body contacts, discharging of simultaneously working is convenient for changing again simultaneously.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is front view of the present invention.
In figure: 1, punch fixing plate; 2, discharging rubber blanket; 3, punching discharging crossbeam; 4, drift; 5, punching concave die; 6, bed die backing plate.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
The dual material removing mechanism in a kind of cold punching hole as shown in Figure 1, described dual material removing mechanism comprises punch fixing plate 1, punching discharging crossbeam 3, drift 4 and punching concave die 5 form, described drift 4 one end is fixedly mounted on punch fixing plate 1, described punching concave die 5 lower end is placed on bed die backing plate 6, described punching discharging crossbeam 3 is fixedly mounted on punching concave die 5 upper end, punching discharging crossbeam 3 is provided with the through hole passed for drift 4, discharging rubber blanket 2 is provided with between described punch fixing plate 1 and punching concave die 5, described discharging rubber blanket 2 offers the through hole passed for drift 4.Treat that punched product is placed on inside punching concave die 5, drift 4 wraps up padded coaming, during punching campaign, padded coaming first touches product back punching head 4 down punching, and after during reply, drift 4 first leaves product, padded coaming leaves, and utilizes punching discharging crossbeam 3 to peel off product downwards simultaneously.Padded coaming is utilized to make product be in relative static conditions all the time before, during and after punch process.The height of described discharging rubber blanket 2 is greater than the length of drift 4 body.The diameter of the through hole that described discharging rubber blanket 2 is offered is less than the diameter of drift 4.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
