Abstract
The utility model discloses a punching device for an isolating insertion plate to be hole-knocked of a plastic shell circuit breaker, which comprises an air cylinder, a connecting rod, a cam, a lateral plate, a lever, a bracket, a top plate, a punch, a base, a bottom plate, a base and the like. A spring and a screw are arranged in the punch. The punch which can vertically slide in the base is fixedly connected with the top plate by the screw in the punch and is embedded in the base. When in punching, the air cylinder horizontally moves forwards, and the cam jacks the lever so as to lead one end of the lever to be in contact with the screw in the punch and meanwhile press the punch, thereby smoothly punching out the needed hole on the insertion plate fixed on the base through knocking.
Description
Technical field
The utility model relates to a kind ofly isolates plate hole to be struck to low-pressure plastic shell circuit breaker and excises the blanking units of processing, belongs to machinery manufacturing technology field.
Background technology:
Breaker of plastic casing need excise processing to its hole to be struck that isolates plate when installing hand behaviour, electrically operated institution additional.What tradition was isolated plate waits that striking hole excision processing way is with pliers this hole to be struck to be cut by hand, and then handles smooth with instruments such as files to the hole.Though it is simple that this method seems, but have the following disadvantages: (one) working (machining) efficiency is low, and the inserting plate hole size that security is lower, (two) are processed into is difficult to unified, and influence is installed, (three) are easily manual, it is attractive in appearance to be assembled on the breaker influence, and is easy to generate waste product.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of working (machining) efficiency height, and is easy to use, and the breaker of plastic casing that can not destroy the plate surface is isolated plate and waited to strike the blanking units in hole.
A kind of breaker of plastic casing described in the utility model is isolated plate and is waited to strike the blanking units in hole, includes parts such as cylinder, connecting rod, cam, side plate, lever, support, top board, drift, pedestal, base plate, base.Be provided with spring and screw in the drift; Drift is fixedlyed connected with top board by the drift screw, and is embedded among the pedestal, and drift can vertically slide in pedestal; When die-cut, the level by cylinder travels forward, and utilizes cam to push lever, makes an end of lever contact and drift is pressed down with the drift screw, like this, can go out hole needed to be struck at the plate that will be fixed on the base smoothly.
Through the utility model after the above-mentioned design, simple in structure, easy to operate, it is compared with traditional manual processing mode, not only processing safety has obtained effective assurance, and the precision of working (machining) efficiency and processing effectively improves, and guarantees that the hole to be struck that is processed accomplishes 100% qualification rate.

Wherein: 1-cylinder 2-connecting rod 3-cam 4-side plate 5-lever 6-support 7-top board 8-plate 9-drift screw 10-spring 11-screw 12-drift 13-pedestal 14-base plate 15-base
The specific embodiment:
A kind of breaker of plastic casing described in the utility model is isolated plate and is waited to strike the blanking units in hole, includes parts such as cylinder 1, connecting rod 2, cam 3, side plate 4, lever 5, support 6, top board 7, drift 12, pedestal 13, base plate 14, base 15.Wherein cylinder 1 is connected with connecting rod 2 one end hinges, and connecting rod 2 other ends are connected with cam 3 one end hinges, and the other end of cam 3 is hinge with side plate 4 and is connected.One end of lever 5 contacts with cam 4, and the other end is hinge with support 6 and is connected.In drift 12, be provided with spring 10 and screw 11; Drift 12 is fixedlyed connected with top board 7 by drift screw 9, and is embedded among the pedestal 13, and drift 12 can vertically slide in pedestal 13.Drift 12 can wait that the needs that strike the different bores in hole change according to isolating plate.
When die-cut, at first will need die-cut plate 8 it accurately to be installed and be positioned on the base 15, and make drift 12 over against its processing plane by pedestal 13.Level by cylinder 1 travels forward, driving cam 3 through connecting rod 2 rotates counterclockwise around the hinge place of side plate 4 with cam 3, utilize the difference of cam 3 eccentric throws, pushing lever 5 makes it to clockwise rotate around the hinge place of lever 5 with support 6, lever 5 one ends are pressed under contacting with drift screw 9 and inciting somebody to action, like this, can on plate 8, go out hole needed to be struck smoothly.After this process finishes, cylinder 1 level retraction, pulling cam 3 is got back to initial position, and lever 5 is also got back to initial position under the gravity effect, and drift 12 is also got back to initial position under the effect of compression spring, and the time processing process is finished at this point.
If need the hole to be struck of die-cut different bores on the plate 8,, can on same blanking units, can realize by same working method by changing the drift of different bores.
