Abstract
The utility model provides a waste rebound preventing structure for punching, which comprises a punch, wherein the punch is fixed on a punch fixing plate; a stripper plate is arranged below the punch fixing plate; a concave sleeve is arranged right below the punch and is arranged on a lower backing plate; and a channel is arranged in the lower backing plate. The waste rebound preventing structure is characterized in that the channel is communicated with a gas inlet channel arranged in the lower backing plate, and the gas inlet channel is connected with a gas tube through a joint. According to the equipment provided by the utility model, gas is utilized to prevent waste from rebounding, the waste rebound preventing structure is suitable for small holes, and the defect rate of parts in the production process and the fault rate of a mould are reduced.
Description
Technical field
The utility model relates to the structure that a kind of punching prevents the waste material rebound.
Background technology
As shown in Figure 1, for common punching at present prevents waste material rebound structure, comprise primary and secondary drift 1, primary and secondary drift 1 is fixed on the drift fixed head 2, below drift fixed head 2, be provided with stripper 3, be provided with recessed cover 4 under primary and secondary drift 1, recessed cover 4 is located on the lower bolster 5, has the passage 6 of allowing that waste material 7 passes through in lower bolster 5.
Said structure adopts the form that adds push rod on drift to prevent the waste material resilience by push rod, but only is fit to macropore, and aperture can't add push rod on drift.
Summary of the invention
The purpose of this utility model provides a kind of anti-waste material rebound structure that can be fit to aperture.
In order to achieve the above object, the technical solution of the utility model has provided the anti-waste material rebound of a kind of punching structure, comprise drift, drift is fixed on the drift fixed head, is provided with stripper below the drift fixed head, is provided with recessed cover under drift, recessed being sheathed on the lower bolster, have passage in lower bolster, it is characterized in that: passage communicates with the inlet channel of opening in lower bolster, and inlet channel connects tracheae by joint.
The equipment utilization gas that the utility model provides prevents the waste material resilience, can be applicable to aperture, reduces the fraction defective of part in the production process, reduces the spoilage of mould.
Description of drawings
Fig. 1 prevents waste material rebound structural representation for former punching;
The anti-waste material rebound of a kind of punching structural representation that Fig. 2 provides for the utility model.
The specific embodiment
Provide a preferred implementation of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 2, the utility model provides a kind of anti-waste material rebound structure, comprise drift 8, drift 8 is fixed on the drift fixed head 2, is provided with stripper 3 below drift fixed head 2, is provided with recessed cover 4 under drift 8, recessed cover 4 is located on the lower bolster 5, have passage 6 in lower bolster 5, passage 6 communicates with the inlet channel of opening in lower bolster 5 11, and inlet channel 11 connects tracheae 9 by joint 10.
The utility model mainly is to connect gas in the material spilling hole side of recessed cover 4, and gas is given vent to anger along leaking the material direction downwards, and waste material is attracted downwards, and waste material is not knock-oned.Gas is on the equipment of being connected, and produces air pressure by equipment, and punch press work one stroke blows once gas automatically in punching course.
The equipment that the utility model provides is applicable to the hole of regular geometry, and the aperture is less than 3.5mm, and item number is less than below the 3mm.
