Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1-5, a robot chassis punching die comprises an upper punching die and a lower punching die;
the upper punching die comprises an upper die bottom plate 11, an upper guide post 12, an upper die 13, a guide sleeve 14 and an upper punching knife;
the lower punching die comprises a lower die bottom plate 21, a lower die supporting plate 22, a lower guide post 23, a guide rail seat 24 and a lower punching knife 25;
the upper die 13 is mounted at the bottom of the upper die bottom plate 11, and the upper punch is arranged on the upper die bottom plate 11 or the upper die 13;
the guide sleeves 14 are respectively arranged at two ends of the upper guide pillar 12, and the upper guide pillar 12 is arranged between the upper die base plate 11 and the guide rail seat 24; in this embodiment, the number of the rail holders 24 is two, and the rail holders are located on two sides of the lower punch die;
the lower die supporting plate 22 can be slidably arranged on the guide rail seat 24;
the lower die bottom plate 21 is positioned below the guide rail seat 24;
the lower guide post 23 is arranged between the lower supporting plate 22 and the lower die bottom plate 21;
the lower punch 25 is disposed on the lower die base plate 21.
In the embodiment, the robot chassis punching die is positioned by adopting the shape of the casting blank on the basis of the size of the casting blank, and the pouring channel is removed, so that the pouring channel excess material of the product can reach less than or equal to 0.5 mm.
Before punching, the sprue of the casting blank is not contacted with the upper punching cutter or the lower punching cutter 25; when the upper die is pressed downwards (the upper die is pressed downwards by an external force and can be driven by an oil cylinder generally), the upper die 13 contacts with a product to apply pressure to the product, the lower die supporting plate 22 is pressed to move downwards, the upper die bottom plate 11 and the upper punch synchronously press downwards, and the knife edges of the upper punch and the lower punch 25 are contacted with a casting blank sprue to break the sprue.
The specific stamping process is as follows: and (3) placing the movable die blank surface of the casting blank downwards on the lower die, positioning the casting blank through the profiling positioning module on the lower die supporting plate 22, wherein in the process of pressing the upper die, the upper die 13 firstly touches the casting blank to enable the casting blank to be gradually pressed in the range of a planeness tolerance zone, the upper die cutter presses downwards to cut off the sprue, and the punching process is completed along with the return of the upper die. The upper guide post 12 is matched with the guide sleeve 14, and plays a role in guiding when the upper punch is pressed down and returned; likewise, the lower guide post 23 also serves as a guide.
The principle of stamping: the lower die bears the pressure of the casting blank transmitted by the upper die, so that the casting blank can generate micro deformation under the 0.2mm clearance of the profiling positioning module; under the condition of ensuring that the casting blank deforms under pressure, the position of a blank sprue is still within the range of 0.5mm, and the residual quantity of a punching sprue is ensured to be less than or equal to 0.5 mm; the design of the punching cutter adopts a split combination mode, and the maintenance cost of the punching cutter is reduced through the distribution of the cutter types.
Therefore, through the utility model discloses a die-cut mould in robot chassis can directly get rid of the product runner, avoids the manual work to get rid of the runner and causes the product to warp, saves the back process and handles, avoids polishing the dust that the foundry goods produced and produces the influence to the environment.
