Abstract
The invention relates to a blanking die for a disk-shaped workpiece, in particular to a blanking die used for punching an initial disk-shaped workpiece during a manufacture process of a cup cylinder block on a right angle valve. The blanking die is characterized by comprising an upper base plate and a lower base plate. Guiding holes are reserved on corresponding positions on two sides of the upper base plate and the lower base plate. A guiding column is disposed in a corresponding pair of guiding holes. Each guiding column is fixedly connected onto the lower base plate and movably connected onto the upper base plate. A punching die is fixed above the lower base plate and a round hole is reserved on the punching die. A cylindrical punch is fixed under the upper base plate, the diameter of the punch is identical with that of the round hole and the punch is concentric with the round hole. By using the blanking die to produce the initial workpiece, energy consumption and production cost are low, quality of the workpiece is fine, and rejection rate is low.
Description
Technical field
The present invention relates to a kind of diel.Specifically, be to be used for the blanking die of the initial disk shape of punching press workpiece on the right angle valve in the cup-shaped cylinder block manufacture process.
Background technology
At present at mechanical processing industry; Being used for making the method that the cup-shaped cylinder block adopts on the right angle valve mainly is casting method; Promptly utilize cup-shaped counterdie and column patrix; When pouring molten metal into the cup-shaped counterdie, the column patrix is got in the cup-shaped counterdie, thereby molten metal is cast into the cup-shaped work piece blank.Then, again metal blank is carried out cut, process required cup-shaped work piece.Come metal is carried out melting owing to adopt casting method need be equipped with smelting furnace, it is more to consume energy, and production cost is high.Impurity content owing to employing casting method requirement molten metal is low especially again, otherwise the workpiece content that casts out is prone to bubble.Therefore, the cylinder block that adopts casting method to produce is second-rate, and percent defective is higher.
Summary of the invention
The problem that the present invention will solve provides a kind of disk shape workpiece blanking die.The workpiece that adopts this disk shape workpiece blanking die to be stamped to form promptly can be made into the cup-shaped cylinder block through follow-up stamping press again, and the power consumption of entire job process is few, and production cost is low.And, adopting the workpiece of this die production, quality is good, and percent defective is low.
For addressing the above problem, the present invention takes following technical scheme:
Disk shape workpiece blanking die characteristics of the present invention are to comprise upper plate and lower shoe, on the relevant position of said upper and lower bottom plate both sides pilot hole are arranged all, in every corresponding a pair of pilot hole a lead are arranged.Be between said lead and lower shoe and be fixedly connected, be between lead and upper plate and be slidingly matched.Said lower shoe upper fixed has punch die, and circular hole is arranged on the punch die.Said upper plate below is fixed with drift, drift be cylindrical and diameter and punch die on Circularhole diameter equate that drift is concentric with the circular hole on the punch die.
In the circular hole that further improvement project of the present invention is said punch die rubber is arranged, there is first top board of disk shape rubber top, and Circularhole diameter equates on the first top board diameter and the punch die.The thickness that the thickness of punch die equals rubber adds the thickness of first top board.Like this, help after stamping press is accomplished, can very easily the disk shape workpiece in the punch die circular hole being taken out.
The outside that further improvement project of the present invention is said drift is with second top board of elastic tape and annular from top to bottom respectively, and the thickness that the thickness of drift equals elastic tape adds the thickness of second top board.Like this, help after stamping press is accomplished, can very easily the sheet material defective material that is enclosed within on the drift be removed.
Take such scheme, have the following advantages:
Can be found out by such scheme, adopt disk shape workpiece blanking die of the present invention required initial workpiece to be provided for cup-shaped cylinder block subsequent job, compare with the conventional cast method, not need smelting furnace, power consumption is few, can reduce production costs.Because the present invention adopts drift, punch die and stamping machine that metallic plate punching is become disk shape workpiece, the quality quality of sheet metal has determined the quality of workpiece, as long as select sheet material such as stainless steel materials preferably for use, just can guarantee the quality of workpiece.Therefore, compare, can avoid the generation of bubble in the workpiece, guarantee the quality of workpiece, reduce the percent defective of workpiece greatly with background technology.
Description of drawings
Fig. 1 is a disk shape workpiece blanking die structural representation of the present invention.
The specific embodiment
As shown in Figure 1, disk shape workpiece blanking die of the present invention comprises upper plate 3 and lower shoe 9, on the relevant position of said upper and lower bottom plate both sides pilot hole is arranged all, in every corresponding a pair of pilot hole a lead 6 is arranged.Said lead 6 is with 9 of lower shoes and is fixedly connected, and 3 of lead 6 and upper plates are and are slidingly matched.In the pilot hole of upper plate 3, be provided with fairlead in the present embodiment, fairlead is enclosed within on the lead 6, thereby realizes being slidingly matched between upper plate 3 and the lead 6.Said lower shoe 9 upper fixed have punch die 5, on the punch die 5 circular hole are arranged.Said upper plate 3 belows are fixed with drift 4, drift 4 be cylindrical and diameter and punch die 5 on Circularhole diameter equate that drift 4 is concentric with the circular hole on the punch die 5.
During work; Earlier the upper and lower base plate with disk shape workpiece blanking die of the present invention is separately fixed on stamping machine footstock, the base, and this moment, upper and lower base plate position should be corresponding, again will sheet metal to be punched be put on the punch die 5 of mould lower shoe 9 and fully with circular hole covering on the punch die 5; Then; Utilize stamping machine to drive mould upper plate 3 and descend fast, make in the circular hole on the drift 4 entering punch dies 5, metallic plate is struck out disk shape workpiece; At last; Utilize stamping machine to drive upper plate 3 and rise with drift 4, rely on the elastic force of rubber 8 in punch die 5 circular holes to drive first top board 7 and disk shape workpiece is ejected punch die 5 and it is taken off, the sheet material defective material that is enclosed within on the drift 4 can drive second top board 1 through the elastic force of elastic tape 2 with its removal.
