Description
Technical field
The present invention relates to field of machining, particularly the location processing mold of hole of spoke.
Background technology
Spoke is the protection wheel rim of wheel of vehicle, the device of spoke; it is characterized in that a pair circular cover plate; the diameter of cover plate and the diameter of wheel rim are close; there are the hole being greater than axis of wheel rotation in the central authorities of cover plate; connect antermarginal part at cover plate and have aperture; there is annular wheel plate at the edge of cover plate, and the curved surface of wheel plate can fit tightly with the curved surface of wheel rim.Along with the fast development of automobile industry, the product quality of spoke also receives much concern, and hole of spoke is the key factor of the serviceability affecting spoke.At present, each wheel shop, being utilize the active force between wheel spoke mesopore and blanking die positioning disk to hole of spoke processing, carries out list to spoke or diplopore punch press process obtains.
Chinese patent publication No. CN103736826A discloses a kind of hole of spoke diplopore processing mold, comprise stamping machine patrix and the counterdie for tilting to install spoke, on counterdie, front side is provided with for the tilting wheel disc of locating and drive spoke to rotate, the punching projection matched with spoke curved edge bottom surface is provided with on rear side of wheel disc, be provided with two drifts below patrix, punching projection upper surface is provided with two counterbores in order to the descending cooperating of drift.This patent can carry out diplopore processing to the air holes of spoke, and location is reliable, and working (machining) efficiency is high, and the air holes that processing obtains is evenly distributed.But, there is following problem: in this patent, wheel disc is ratchet, blocks ratchet by ratchet, ratchet is located, prevent ratchet backwards rotation simultaneously.In order to carry out punching to spoke, being fixed on by spoke above the ratchet be obliquely installed, then carrying out punching by the drift of patrix to it, drift applies, greatly to lower punch power, ratchet easily to be rotated clockwise to spoke, and punching location goes wrong.
Summary of the invention
The object of this invention is to provide the location processing mold of hole of spoke, accurately can locate spoke, prevent ratchet from rotating clockwise.
The invention provides a kind of base case: the location processing mold of hole of spoke, comprise upper bolster, upper die and lower die seat and counterdie, patrix cooperatively interacts with upper bolster and is connected, and is provided with support bar and the drift being fixedly connected on support bar end below patrix; Counterdie cooperatively interacts with die shoe and is connected, on counterdie, front side is provided with for the tilting wheel disc of locating and drive spoke to rotate, the punching projection matched with spoke curved edge bottom surface is provided with on rear side of wheel disc, triggering block is provided with above the end sidewalls of support bar, the top of punching projection is provided with electromagnet, be positioned at travel switch and power circuit that punching projection side is provided with fixed mount and is positioned at fixed mount end above counterdie, travel switch is electrically connected with electromagnet.
Operation principle and beneficial effect are: be arranged on by spoke back-off to be processed and position above wheel disc and fix, the curved edge of spoke is placed on above punching projection, then promote upper bolster to move downward, patrix moves downward, and support bar drives drift to move downward, when triggering block above support bar touches travel switch, travel switch cuts out, and power circuit has electric current to pass through, electromagnet conducting and hold spoke, drift is when spoke curved edge top rushes air holes, and wheel disc can not rotate.When punching is complete, upper bolster drives patrix and drift to move upward, and triggering block leaves travel switch, and travel switch is opened, and power circuit no current passes through, and the magnetic of electromagnet disappears.Rotating wheel disk, makes it turn to next punching position, repeats above action, until the air holes punching above spoke curved edge is complete.
Beneficial effect in the present invention: 1, adopt wheel disc to position spoke, because the air holes surface of spoke is inclination cambered surface, in order to punching hole when is in horizontal plane, be conducive to punching, so be obliquely installed by wheel disc, just the curved edge of spoke is on horizontal plane, facilitates punching.2, the punching projection that arranges below of wheel disc, facilitate the descending punching of drift, punching projection is to curved edge support force of spoke, electromagnet inside the projection of punching simultaneously, for when drift is descending, electromagnet holds spoke, when making the impulsive force of punching larger, wheel disc can not rotate clockwise, and ensures the accurate location of punching.3, the cooperation of triggering block wherein and travel switch, is to make power circuit have electric current to pass through, thus electromagnet energising.
Further prioritization scheme one for base case: power circuit comprises protective resistance, single-phase bridge type rectification circuit and alternating current steady voltage plug.Be energized to make electromagnet; be provided with power circuit; wherein alternating current steady voltage plug mainly provides alternating current; and single-phase bridge type rectification circuit utilizes the rectifier cell with unilateal conduction performance; the positive and negative sinusoidal voltage rectification replaced is become unidirectional pulsating volage; it is made to become DC current, and the main dividing potential drop of protective resistance thus circuit is played a protective role.
Further prioritization scheme two for base case: wheel disc upper surface is provided with the protruding pin coordinated with spoke mesopore and the alignment pin matched with spokes.By protruding pin and alignment pin, the mesopore of spoke and bolt hole are positioned, the free degree of mesopore and bolt hole can be limited, thus location is reliable.
Further prioritization scheme three for base case: counterdie is provided with the tilting projection seat be positioned on rear side of wheel disc, wheel disc is connected with the bore rotatable engagement in projection seat by its lower surface.Arrange the rotation that projection seat is convenient to wheel disc, projection seat can by wheel disc inclined shore simultaneously.
Further prioritization scheme four for base case or prioritization scheme two: wheel disc is ratchet, and counterdie is provided with the convex axle being positioned at described ratchet side, convex axle upper end is rotatably connected the ratchet matched with described ratchet, is folded with torsion spring between ratchet and described convex axle.Wherein ratchet can position ratchet, is evenly provided with ratchet above ratchet, as even index dial, can ensure that the position of air holes in spoke punching is uniformly distributed.Meanwhile, between ratchet and convex axle, be folded with torsion spring, conveniently can rotate ratchet, thus block ratchet.
Further prioritization scheme five for base case: die shoe both sides are provided with lead, patrix is provided with the pilot hole matched with described lead.Die shoe arranges lead, being mainly used in guiding, its punching direction can not being departed from, simultaneously for supporting upper bolster and die shoe.
Further prioritization scheme six for prioritization scheme five: be provided with stage clip above the lead being positioned at die shoe both sides.In order to ensure completing smoothly of punching, the reset after punching simultaneously terminates, arranges stage clip for this reason on lead.
Further prioritization scheme seven for base case: patrix lower surface is provided with stripper, and stripper is connected by spring with patrix, drift is through described stripper.Because drift carries out punching to spoke border, its waste material can be bonded at nose of punch, arranges stripper and spring for this reason, can after drift punching completes, and spring sets back, and drift moves upward, and promotes stripper and moves downward, thus carry out discharging to it.
