Summary of the invention
The purpose that the utility model is created is to provide a kind of processing technology simple, and solves the pressing equipment of hydraulic tappet housing residual technical problem of burr behind hole forming.
For achieving the above object, the utility model adopts following technical scheme:
Hydraulic tappet inner walls outwash formula punching apparatus is characterized in that this punching apparatus comprises
The tappet shell clamping device: be used for the device of clamping tappet shell workpiece,
And hole punched device: be used for the device of hydraulic tappet inwall outwash formula punching,
Described hydraulic tappet shell clamping device comprises a V-arrangement base that is fixed in base plate, and one is in V-type briquetting on the same level face with the V-type base, and this V-type briquetting is connected with the cylinder of punching press clamping work pieces;
Described hole punched device comprises
A drift base plate mechanism that connects firmly with base plate, the wobbler action when being used for offsetting punching press,
A plunger mechanism of being located in the tappet housing, contain one with housing shaft to consistent drift, for radially impulse force is provided;
A punching pin mechanism that is located in the tappet housing, contain one with housing shaft to vertical punching pin, the radially impulse force for accepting plunger mechanism makes it to change into the horizontal impulse force for the tappet inner walls.
Further, described ram bottom end face is an inclined-plane, and described punching pin one end contains one and draws the inclined-plane with corresponding the connecing in drift inclined-plane, realizes that by the shear action between two inclined-planes radially impulse force is to the transformation of horizontal impulse force.
Further, described drift base plate mechanism comprises drift base plate, bearing plate and connection square key between the two, and drift base plate and base plate are affixed, bearing plate support tappet housing outer wall.
Further, described plunger mechanism comprises a drift, and drift top cover has the drift spring, and the drift upper end connects the cylinder connector, and the end socket of this cylinder connector is used for filling up the interstage sleeve in space between cylinder connector and the tappet housing.
Further, described punching pin mechanism comprises punching pin and supporting punching pin spring.
The utility model is controlled respectively two cover winding machine hydraulic tappet housings with two cylinders and is clamped and hydraulic tappet inner walls outwash.Clamping cylinder is realized Workpiece clamping under the thrust of cylinder by the V-type briquetting of activity and the V-type base that connects firmly.Stamping cylinder promotes drift by the cylinder connector under the thrust of cylinder, drift slides and promotes punching pin realization workpiece inwall outwash.
Compare with outside measuring punching mode with outboard boring, this structure punching mode is that its beneficial effect is by the punching of hydraulic tappet inwall to cylindrical:
1, can effectively avoid occurring burr or punching after burr stay (if jagged) on the external diameter, remove easily burr;
2, can be with centrifugal polishing machine together roll cast after punching is finished, efficient is high, reduces in a large number process time and cost, and can fully get rid of burr.
Description of drawings
Fig. 1 is that the utility model is implemented structural representation.
The local enlarged diagram in A place of Fig. 1 when Fig. 2 is place work piece.
Among the figure: clamping cylinder head 1, V-type briquetting 2, tappet workpiece 3, punching pin mechanism 40, punching pin interstage sleeve 41, punching pin 42, punching pin spring 43, drift 44, cylinder connector 45, drift interstage sleeve 46, drift spring 47, drift base plate mechanism 50, V-type base 6, base plate 7, drift base plate 8, square key 9, bearing plate 10.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
