Abstract
The invention discloses a clamp for plane milling of an upper die plate of a stamping die. The clamp comprises a rack, a fixing seat, lug plates, a pressure plate, a push rod, a steel ball and a pull rod, wherein the fixing seat is positioned on the top of the rack; the lug plates are positioned on two sides of the fixing seat; the middle of the pressure plate is pivotally arranged on the lug plates; the push rod is hinged to the lower end of the pressure plate; a horizontal channel is formed in the bottom of the rack; the pull rod slides along the horizontal channel; two inclined channels which are inclined relative to the horizontal direction are formed in the middle of the rack; the two inclined channels and the horizontal channel are connected to one another at a position of a connecting opening; the steel ball is positioned at the position of the connecting opening; the lower end of the push rod is abutted to the steel ball; a notch is formed in the middle of the pull rod; and the steel ball can move in the up-down direction through the notch. The clamp is simple in structure and easy to operate, facilitates clamping and is suitable to be popularized.
Description
Technical field
The present invention relates to part manufacture field, a kind of upper die of stamping die plate of specific design milling flat fixture.
Background technology
Diel is in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product), is called cold punching die (being commonly called as cold-punching mould).Punching press is at room temperature, utilizes the mould be arranged on forcing press to apply pressure to material, makes it produce separation or plastic deformation, thus obtains a kind of pressure processing method of required part.
Diel generally comprises die shank, cope match-plate pattern, upper die and lower die and lower bolster, because patrix will be fixed on cope match-plate pattern, so the fineness of cope match-plate pattern is just important, directly affects the precision of mould; And the fixture more complicated of current cope match-plate pattern milling flat, clamping inconvenience.
Summary of the invention
The invention is intended to provide a kind of upper die of stamping die plate milling flat fixture, so that clamping cope match-plate pattern.
Upper die of stamping die plate milling flat fixture in this programme, otic placode, the middle part of the holder both sides that comprise frame, are positioned at the holder of frame top, are positioned at are hubbed on the pressing plate on otic placode, the push rod being hinged on pressing plate lower end, steel ball and pull bar; Be provided with horizontal channel bottom frame, pull bar slides along horizontal channel; Central rack is provided with two ramp ways tilted with horizontal direction, and two ramp ways and horizontal channel are communicated in connected entrance place, and steel ball is positioned at connected entrance place, and push rod lower end is against on steel ball, are provided with the breach that steel ball can be made to move up and down in the middle part of pull bar.
Compared with prior art, the invention has the advantages that: otic placode, the middle part of the holder both sides that comprise frame, are positioned at the holder of frame top, are positioned at are hubbed on the pressing plate on otic placode, the push rod being hinged on pressing plate lower end, steel ball and pull bar, pressing plate one end can be made to press to the cope match-plate pattern be positioned on holder under push rod promotes, thus cope match-plate pattern is fixed, be provided with horizontal channel bottom frame, pull bar slides along horizontal channel, central rack is provided with two ramp ways tilted with horizontal direction, two ramp ways and horizontal channel are communicated in connected entrance place, steel ball is positioned at connected entrance place, push rod lower end is against on steel ball, the breach that steel ball can be made to move up and down is provided with in the middle part of pull bar, steel ball is stuck in pull bar indentation, there, pull pull bar that steel ball can be made to move upward along pull bar breach, now pull bar breach plays the effect of cam, when steel ball moves upward, when can promote push rod, pressing plate lower end upwards swings, be hubbed on otic placode in the middle part of pressing plate simultaneously, forming is pivoted a little for the lever of fulcrum with pressing plate, pressing plate upper end can compress downwards the cope match-plate pattern be positioned on holder, milling flat can be carried out, structure of the present invention is simple, and processing ease, is convenient to clamping, is suitable for promoting.
Further, pull bar bottom one end and horizontal channel of horizontal channel between be connected with the first spring.
Further, push rod convexes to form top near steel ball one end, increases the lifting surface area of push rod.
Further, between top and ramp way, be provided with abrasive rubber cover, avoid phase mutual friction between top with ramp way.
Further, described ramp way threaded upper ends is connected with dust cap, and dust cap can prevent from dust from dropping in ramp way causing push rod to wear and tear, and is provided with the second spring, is convenient to automatically reset when push rod unclamps workpiece between dust cap and top.
Further, be provided with anti-rotation groove bottom pull bar, side, horizontal channel is connected with anti-turn screw, and anti-turn screw extend in anti-rotation groove, prevents pull bar from rotating, and affects fixture and uses.
