Abstract
The utility model discloses a stamping part ejecting device, which can be used for conveniently and rapidly adjusting the magnitude of ejecting force in order to overcome the defect that the magnitude of the ejecting force cannot be adjusted rapidly in the conventional stamping part ejecting device. The stamping part ejecting device comprises a piston and a gas-enclosed base, wherein the piston is connected with the base in a sliding way; the piston is provided with a carrier rod which is vertical to the piston; one end, which is far away from the piston, of the carrier rod is provided with an ejecting head; one end, which is close to the ejecting head, of the base is provided with outer threads. The stamping part ejecting device is suitable for occasions where the conventional stamping part ejecting device is suitable for, and has the advantages of capability of conveniently and rapidly changing the magnitude of the ejecting force, small interference with surrounding objects, difficulty in causing collision and damages, and the like.
Description
Technical field
The utility model belongs to mould accessory field, relates in particular to a kind of stamping parts bullet ejection device.
Background technology
In die industry, especially at the automatic production line of stamping factory.Due to stamping parts in process of production, can there is complicated deformation in steel plate materials, add, steel plate materials has certain plastic property, so cause steel plate materials after punching press is complete, be especially easily stuck in the die cavity of mould, cause robot to capture or cannot blanking.In order to prevent that stamping parts is stuck on the die cavity of mould, need on the die cavity of mould, increase such as Lifting Device such as springs.Yet, although existing Lifting Device can realize the function of liftout, can not adjust comparatively easily bullet top power, when needs are adjusted bullet top power, can only adopt and change different springs or to adopting other compressing structures to apply the method for external force to bullet ejection device, waste time and energy, very inconvenient.
China Patent Publication No. CN202348879U, open day on July 25th, 2012, the name of utility model is called bullet ejector pin, this application case discloses a kind of bullet ejector pin, it is characterized in that, described bullet ejector pin is provided with cylinder base, and described base is provided with cylindrical body supports platform, the top of described brace table is provided with hemispherical plunger, and the diameter of described brace table is less than the diameter of base; The upper and lower periphery of described cylinder base is equipped with the chamfering of 45 degree.If this utility model weak point is to be made into elastic device for bullet top stamping parts, in the time need to changing bullet top power big or small, need to change and play head part or increase compressing structure, operation inconvenience, wastes time and energy.
Utility model content
The utility model has overcome the deficiency that existing stamping parts bullet ejection device can not quick adjustment bullet top power size, and a kind of stamping parts bullet ejection device that can regulate quickly and easily bullet top power size is provided.
The utility model is achieved through the following technical solutions:
A kind of stamping parts bullet ejection device, comprise piston, be closed with the base of gas, described piston is connected with base sliding, and described piston is provided with the push rod vertical with piston, described push rod is liftout head away from one end of piston, and described base is provided with external screw thread near one end of liftout head.Base inner sealing has gas, therefore, after push rod is under pressure, can drive piston compression gas, and gas can apply reaction force to piston.While using the utility model, offer the screw corresponding with external screw thread on mould, base can be screwed in screw, push rod, towards stamping parts place direction, can contact and withstand stamping parts when punching press.Because push rod length is certain, the gas flow of sealing is certain, therefore when base screw-in length changes, the overhang of push rod also changes, and when push rod touches stamping parts and pushed back, different screw-in amounts cause piston stroke also different, maximum bullet top power has also just changed size naturally thereupon, therefore when needs change bullet top power size, only need to adjust the degree of depth that base screws in screw on mould, screw in deeplyer, bullet top power is larger, screw in more shallowly, bullet top power is less.
As preferably, described liftout head is hemispherical, and described liftout head and push rod are integral type structure.Liftout head is hemispherical, is therefore that point contacts with stamping parts, and the laminate surface that is difficult for liquidating causes scrapes damage, can effectively realize liftout function again.
As preferably, described base is cylindrical, and the length that described external screw thread covers is greater than 1/10th of base length.The interference of columnar base and periphery object is less, is difficult for bumping, no matter simultaneously turn to which angle, does not have sharp-pointed angle, limit is exposed, and is difficult for the damage that bumps.
Therefore, the beneficial effects of the utility model are: (1) only needs the screw-in depth of adjusting base, just can change easily the size of bullet top power; (2) little with the interference of periphery object, damage is difficult for bumping.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: piston 1, base 2, push rod 3, liftout head 4.
The specific embodiment
Below by embodiment, by reference to the accompanying drawings the technical solution of the utility model is described further:
A kind of stamping parts bullet ejection device as shown in Figure 1, comprise piston 1, be closed with the base 2 of gas, described piston 1 is slidably connected with base 2, described piston 1 is provided with the push rod vertical with piston 13, described push rod 3 is liftout head 4 away from one end of piston 1, and described base 2 is provided with external screw thread near one end of liftout head 4.Base 2 inner sealings have gas, therefore, after push rod 3 is under pressure, can drive piston 1 Compressed Gas, and gas can apply reaction force to piston 1.While using the utility model, offer the screw corresponding with external screw thread on mould, base 2 can be screwed in screw, push rod 3, towards stamping parts place direction, can contact and withstand stamping parts when punching press.Because push rod 3 length are certain, the gas flow of sealing is certain, therefore when base 2 screw-in lengths change, the overhang of push rod 3 also changes, and when push rod 3 touches stamping parts and pushed back, different screw-in amounts cause piston 1 stroke also different, maximum bullet top power has also just changed size naturally thereupon, therefore when needs change bullet top power size, only need to adjust the degree of depth that base 2 screws in screw on moulds, screw in deeplyer, bullet top power is larger, screw in more shallowly, bullet top power is less.Described liftout head 4 is hemispherical, and described liftout head 4 is integral type structure with push rod 3.Liftout head 4 is hemispherical, is therefore that point contacts with stamping parts, and the laminate surface that is difficult for liquidating causes scrapes damage, can effectively realize liftout function again.Described base 2 is cylindrical, and the length that described external screw thread covers is greater than 1/10th of base 2 length.Columnar base 2 is less with the interference of periphery object, is difficult for bumping, no matter turn to which angle, does not have sharp-pointed angle, limit is exposed, and is difficult for the damage that bumps simultaneously.
