Description
Technical Field
The utility model relates to a balanced cushion with adjustable drawing die.
Background
The drawing die mainly comprises a lower die, an upper die and a blank holder, wherein a balance cushion block is arranged between the blank holder and the upper die, the pressure of a bottom cylinder of the equipment is uniformly distributed on a material pressing surface through the balance cushion block, and the inflow resistance of the sheet material can be controlled by adjusting the height of the balance cushion block, so that the inflow amount of the sheet material is controlled. The adjustment of the balance cushion block is an important means for debugging the drawing die, and has obvious effect on optimizing the defects of wrinkling, cracking, rebound, sliding lines and the like of parts. The balance cushion blocks analyze the blank holder force according to CAE, a certain number of cushion blocks are arranged on the periphery of the blank holder, and each cushion block can independently control the inflow of local materials. Meanwhile, the balance cushion block plays a role in keeping the gap value between the blank holder and the material surface of the upper die pressing stable, and the change caused by the precision fluctuation of the press machine can be eliminated to a certain extent. When the die is checked and accepted to leave a factory, the heights of the cushion blocks are required to be adjusted to be consistent, the specifications and the quantity of the bottom gaskets are consistent, the pressing surface is ground on a new machine tool again after the die is returned to the factory, and the balance cushion blocks are rebalanced after being ground. In the subsequent mass production process, the balance cushion block can be adjusted to optimize the quality of the parts when the quality of the parts is fluctuated. The sizes and the quantities of the cushion blocks adjusted at each time and the added and reduced cushion blocks are inconsistent, so that the quantity of the cushion blocks at the bottom of the balance cushion block is inconsistent, and the cushion blocks cannot be restored after being detached. Therefore, a novel adjustable balance cushion block of the drawing die needs to be invented.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a balanced cushion with adjustable novel drawing die, solve gasket specification, the quantity inconsistent of the balanced cushion increase and decrease after adjusting at every turn in traditional blank holder, lead to the unable scheduling problem that recovers after balanced cushion demolishs.
The utility model provides a technical scheme that its technical problem adopted is:
an adjustable balance cushion block of a drawing die comprises a movable block and a fixed block arranged above the movable block; the upper end surface of the movable block and the lower end surface of the fixed block are both matched inclined surfaces, and the movable block is also provided with an adjusting groove; the position of the fixed block relative to the adjusting groove is provided with an adjusting hole, an adjusting bolt matched with the adjusting groove is arranged in the adjusting hole, and the fixed block can be movably adjusted on the fixed block along the direction of the adjusting groove.
Furthermore, a plurality of lower step surfaces are sequentially and uniformly arranged on the inclined surface of the movable block from top to bottom, and a plurality of upper step surfaces meshed with the lower step surfaces are also arranged on the inclined surface of the fixed block.
Further, the height of the lower step surface and the height of the upper step surface are both 0.1 mm.
Furthermore, the side edges of the lower step surface and the upper step surface are provided with adjusting marks.
Furthermore, the two adjusting grooves are arranged on two sides of the upper end face of the movable block in parallel.
Furthermore, two adjusting holes are also arranged and are respectively positioned at two sides of the fixing block.
The utility model has the advantages that: the adjustable balance cushion block of the utility model has simple structure, strong reliability, simple operation and no need of adjusting gaskets; meanwhile, the adjustment range is wide, the product process parameter change recording table is easier to record, and the fluctuation of the process parameter change to the product quality is convenient to trace.
The present invention will be described in more detail with reference to the accompanying drawings and examples.
Drawings
Fig. 1 is a perspective view of the adjustable balance cushion block of the drawing die of the present invention.
