Description
Technical field
The present invention relates to the technical field of component of machine processing, specifically a kind of plane reshaping tool, particularly relate to a kind of apparatus for shaping for die casting product plane rapid shaping.
Background technology
At present, less than in the thin plate class die casting hot procedure of 5mm thickness, inevitably produce cold events deformation and cause the phenomenon of product plane degree instability, need the product that die casting is completed to carry out re-shaping exercise to meet prescription.In the prior art, the artificial manual operations of general employing, utilize the instruments such as easy rubber hammer that product surface is tapped repeatedly, carry out estimating smooth process in the way of unaided eye discrimination.It is disadvantageously, operator are in reforming process: on the one hand the operating time is long, even the shaping completing a part under skilled worker's general status is minimum wants 3 ~ 5 minutes, causes wasting that the substantial amounts of working time goes repeatedly to tap, eye is surveyed, and causes the wasting of resources；On the other hand quality is unstable, the proficiency level relying on people in batch production process goes the flatness after differentiating shaping to be insecure, the quantitative degree of operative, careful degree are the biggest on the impact of product quality, working sense of responsibility and the state of people also can play critically important factor simultaneously, and the quality of the most whole product is poor in the convenient controllability of flatness.
Summary of the invention
It is an object of the invention to provide the plane reshaping tool of a kind of improvement, it can overcome, and artificial smooth efficiency in prior art is low, the some shortcomings of unstable product quality.
To achieve these goals, the technical scheme is that a kind of plane reshaping tool, it is characterized in that: described plane reshaping tool includes one group of upper and lower fixing plate being correspondingly arranged, upper and lower fixing plate is all rectangle, the upper surface of bottom plate is provided with one group of location guide pin bushing, upper mounted plate lower surface is provided with one group of positioning guide column matched with location guide pin bushing, and location guide pin bushing and positioning guide column are respectively arranged at office in the both sides minor face of upper and lower fixing plate；
The upper surface of bottom plate is provided with four plane guiding mechanisms, and the lower surface of upper mounted plate is provided with four the pressure head reshaping devices matched with four plane guiding mechanisms, and the lower surface medium position of upper mounted plate is provided with an auxiliary and compresses guide pillar；
Pressure head reshaping device is formed by connecting by cylindrical standing part and shaping pressure head, and shaping pressure head is provided with compact heap, and compact heap is provided with seal face and avoiding hollow groove；
The upper surface of bottom plate is provided with a set product detent mechanism, and in bottom plate upper surface long side, office is provided with mistake proofing guide pillar.
During use, this tool is arranged on external pressing equipment, this pressing equipment comprises the stationary work-table of upper and lower mould, to treat that it is coordinated with product orientation mechanism by shaping product by product orientation hole, the interior an actor's rendering of an operatic tune face making product contacts with the loading surface of plane guiding mechanism, start external pressing equipment power supply, its upper table drives the downward punching press of upper mounted plate, by location guide pin bushing and the location of positioning guide column, plane guiding mechanism loading surface docks with pressure head reshaping device, pressure head reshaping device carries out punching press to the product being placed on plane guiding mechanism loading surface, then the time relay installed additional by equipment is rested on product surface and within 15 seconds, is carried out pressurize (depending on the time of staying is according to product attribute).After completing a shaping, punching press equipment belt moves the pressure head reshaping device of this device and plane guiding mechanism is opened, and takes out product, is reentered into immediately and treats that shaping product repeats above-mentioned flow process to needing shaping product to carry out shaping.
The present invention compared with prior art has the advantage that
1. the plane guiding mechanism of bottom plate upper surface is the most applicable, after location guide pin bushing and being accurately positioned of positioning guide column, no matter how die casting plane changes, and plane guiding mechanism and pressure head reshaping device can make quickly adjustment, to reach the plane prescription of client；
2. improve the yield of trimming: manual shaping needs 3 ~ 5 minutes, and uses the training time of this tool to connect lifting workpiece time-consuming 30s altogether, and efficiency at least improves more than 6 times, is especially suitable for large batch of production operation；
3. reducing production cost, shaping effect is good simultaneously, and flatness is better than manual smooth.
