Description

A kind of low noise diel

Technical field

The present invention relates to decompressor, particularly a kind of low noise diel.

Background technology

Punching press is that a kind of mould that utilizes is made sheet metal various en plaque parts and housing, container class workpiece on forcing press, or pipe fitting is made to the method for various tubular workpieces.

Punch process is by means of the power of conventional or special-purpose pressing equipment, makes plate in mould, directly be subject to deformation force and be out of shape, thereby obtains definite shape, the production technology of the product parts of size and performance.Plate, mould and equipment are the three elements of punch process.By punch process temperature, be divided into drop stamping and cold stamping.It is high that the former is applicable to resistance of deformation, the Sheet Metal Processing that plasticity is poor; Latter at room temperature carries out, and is the process for stamping that thin plate is conventional.It is one of main method of Metal Forming (or pressure processing), is also under the jurisdiction of forming materials engineering.

The mould that punching press is used is called diel, is called for short punch die.Punch die is that material (metal or nonmetal) batch machining is become to the specific purpose tool of required stamping.Punch die is most important in punching press, there is no satisfactory punch die, and punching production is just difficult to carry out in batches; There is no advanced punch die, advanced Sheet Metal Forming Technology just cannot realize.Sheet Metal Forming Technology and mould, pressing equipment and stamping material form the three elements of punch process, only have them to mutually combine and just can draw stamping parts.Diel has improved production capacity, has saved cost, but in punching course, noise is larger, has a strong impact on operator's physical and mental health.

Summary of the invention

The object of the invention is to overcome the shortcoming of prior art, the diel that a kind of noise is little, efficiency is high, cost is low is provided.

Object of the present invention is achieved through the following technical solutions: a kind of low noise diel, it comprises module, guide pillar and lower module, upper module comprises die shank, cope match-plate pattern, punch and pressing plate, die shank is arranged on cope match-plate pattern upper surface, punch is installed in the middle of cope match-plate pattern lower surface, drift is installed on punch, cope match-plate pattern lower surface surrounding is provided with a plurality of bolts, the outside of each bolt is all set with a spring, spring upper end is connected on the lower surface of cope match-plate pattern, the lower end of spring is connected on the upper surface of pressing plate, described lower module comprises lower bolster and die, die is arranged on lower bolster upper surface, guide pillar is arranged on lower bolster upper surface, described die center starts to have a through hole, lower bolster center offers a dumping pit.

The through hole of described die is concentric with drift.

The through-hole diameter of described die is identical with punch diameter.

The dumping pit of described lower bolster is concentric with drift.

The dumping pit diameter of described lower bolster is greater than the diameter of the through hole of die.

The axial length of described spring is longer than the length of bolt.

The present invention has the following advantages: diel of the present invention, pressing plate slowly contacts with separated with workpiece, make workpiece can not be subject to moment collision, and send loud noise, thereby this diel has advantages of that noise is little, efficiency is high and cost is low.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention

In figure, 1-guide pillar, 2-lower bolster, 3-through hole, 4-drift, 5-dumping pit, 6-die, 7-die shank, 8-pressing plate, 9-bolt, 10-spring, 11-punch, 12-cope match-plate pattern.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:

As shown in Figure 1, a kind of low noise diel, it comprises module, guide pillar 1 and lower module, upper module comprises die shank 7, cope match-plate pattern 12, punch 11 and pressing plate 8, die shank 7 is arranged on cope match-plate pattern 12 upper surfaces, in the middle of cope match-plate pattern 12 lower surfaces, punch 11 is installed, drift 4 is installed on punch 11, cope match-plate pattern 12 lower surface surroundings are provided with a plurality of bolts 9, the outside of each bolt 9 is all set with a spring 10, spring 10 upper ends are connected on the lower surface of cope match-plate pattern 12 through bolt 9, the lower end of spring 10 is connected on the upper surface of pressing plate 8, the axial diameter of spring 10 is longer than the length of bolt 9, described lower module comprises lower bolster 2 and die 6, die 6 is arranged on lower bolster 2 upper surfaces, guide pillar 1 is arranged on lower bolster 2 upper surfaces, described die 6 centers start to have a through hole 3, lower bolster 2 centers offer a dumping pit 5, the through hole 3 of die 6 concentric with drift 4, through hole 3 diameters of die 6 are identical with drift 4 diameters, the dumping pit 5 of lower bolster 2 is concentric with drift 4, dumping pit 5 diameters of lower bolster 2 are greater than the diameter of the through hole 3 of die 6.

The course of work of the present invention is as follows: die shank 7 is connected with hydraulic press, when upper module is descending, pressing plate 8 first contacts with workpiece, and compress workpiece under the effect of spring force, then drift 4 has contacted blanking with workpiece, hydraulic press continues descending, waste material is pushed through to through hole and enter dumping pit, then bolt contacts with pressing plate and realizes spacingly, and then hydraulic press is up, completes processing, in whole process, spring is exerted pressure gradually to pressing plate, and pressing plate slowly contacts with workpiece, makes in whole process noise less.
