Abstract

The invention discloses a punching mold, comprising an upper mold and a lower mold. The punching mold is characterized in that the upper mold is provided with an upper mold base, an upper mold washer, a convex mold and an upper punching layer in sequence from top to bottom; and the lower mold is provided with a vibration preventing plate, a lower mold base, a lower mold washer, a concave mold, a pressing plate and a lower punching layer in sequence from bottom to top. The punching mold is high in pass percent of produced samples, low in fault rate and prominent in noise reducing effect.

Description

A kind of diel

Technical field

The present invention relates to technical field of mold, is specifically a kind of diel.

Background technology

Diel is in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product), is called cold punching die (being commonly called as cold-punching mould).Punching press is at room temperature, utilizes the mould be arranged on forcing press to apply pressure to material, makes it produce separation or plastic deformation, thus obtains a kind of pressure processing method of required part.

Conventional ones mould comprises a bed die and a mold, makes sample by both punching presses.In the course of work, can clash between each plate, the noise produced after clashing into not only has harm to staff's human body, but also causes environmental pollution, particularly height diel, and this kind of noise problem is particularly serious; The vibration that punching press causes after clashing into easily causes the damage of sample and diel; In addition, conventional ones mould cannot carry out Real-Time Monitoring in sample making.

In prior art, patent of invention CN201210335102 by arranging poor groove to carry out minimizing noise, but still is metal covering rigidity head-on collision punching press, vibrate comparatively large, and noise reduction is undesirable in actual job; Patent of invention CN201310266230 is by rubber in conjunction with steel ball layer, and noise reduction is imitated, and still shakes larger in actual job.

Summary of the invention

For prior art produced problem, the present invention proposes following technical scheme:

A kind of diel, comprise patrix 1 and counterdie 2, it is characterized in that, described patrix 1 sets gradually patrix base 11, patrix pad 12, punch 13 and nappe de charriage 14 by order from top to bottom; Described counterdie 2 sets gradually shockproof plate 21, counterdie base 22, counterdie pad 23, die 24, pressing plate 25 and lower cushioning layer 26 by order from the bottom to top.

Described nappe de charriage 14 is divided into three layers, is followed successively by wolfram steel layer 141, rubber layer 142 and titanium dioxide granule layer 143 from the bottom to top.

Described lower cushioning layer 26 is divided into three layers, is followed successively by wolfram steel layer 261, rubber layer 262 and titanium dioxide granule layer 263 from top to bottom.

Described die 24 arranges pressure inductor 27; Described counterdie base 22 arranges alarm 28; Described pressure inductor 27 is connected by wire 29 with alarm 28.

Compared with prior art, the present invention has following beneficial effect:

1, buffer layer is set, reduces rocking and damaging of diel and equipment, improve product percent of pass;

2, nappe de charriage and lower cushioning layer are set, according to contact surface, wolfram steel, rubber, titanium dioxide form combination layer successively from inside to outside for both, the moulding power that wolfram steel hardness, intensity is high to sample when can ensure stamping press, the generation of noise when rubber can reduce stamping press, titanium dioxide granule layer is used for the applanation that is uniformly dispersed, avoid pasting mould during part forming poor, improve product percent of pass;

3, pressure inductor and alarm are set, when operation because of the pressure anomaly that defective operation produces, the real-time monitoring to stamping press can be realized.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is nappe de charriage structural representation;

Fig. 3 is undershoot Rotating fields schematic diagram.

In figure, comprise patrix 1, counterdie 2, mould base 11, patrix pad 12, punch 13, nappe de charriage 14, shockproof plate 21, counterdie base 22, counterdie pad 23, die 24, pressing plate 25 and lower cushioning layer 26, nappe de charriage 1 is followed successively by wolfram steel layer 141, rubber layer 142 and titanium dioxide granule layer 143 from the bottom to top, lower cushioning layer 26 is divided into three layers, is followed successively by wolfram steel layer 261, rubber layer 262 and titanium dioxide granule layer 263 from top to bottom.

Detailed description of the invention

Below in conjunction with specific embodiment, the present invention is described in further detail.

Embodiment 1

The technical program is further illustrated as follows below in conjunction with accompanying drawing:

A kind of diel, comprise patrix 1 and counterdie 2, it is characterized in that, described patrix 1 sets gradually patrix base 11, patrix pad 12, punch 13 and nappe de charriage 14 by order from top to bottom; Described counterdie 2 sets gradually shockproof plate 21, counterdie base 22, counterdie pad 23, die 24, pressing plate 25 and lower cushioning layer 26 by order from the bottom to top; Described nappe de charriage 14 is divided into three layers, is followed successively by wolfram steel layer 141, rubber layer 142 and titanium dioxide granule layer 143 from the bottom to top; Described lower cushioning layer 26 is divided into three layers, is followed successively by wolfram steel layer 261, rubber layer 262 and titanium dioxide granule layer 263 from top to bottom; Described die 24 arranges pressure inductor 27; Described counterdie base 22 arranges alarm 28; Described pressure inductor 27 is connected by wire 29 with alarm 28.

Embodiment 2

Using diel described in patent of invention CN201210335102 embodiment as blank group 1, described in CN201310266230 embodiment, diel is as blank group 2, the embodiment of the present invention 1 as a control group, in identical operation environment, make similar sample, carry out noise vs's test.

Object	Make sample number	Ambient noise (decibel)
			Blank group 1	100	55-61
Blank group 2	100	65-70
			Control group	100	45-55

Visible, diel noise reduction of the present invention is more obvious.

Using diel described in patent of invention CN201210335102 embodiment as blank group 1, described in CN201310266230 embodiment, diel is as blank group 2, the embodiment of the present invention 1 as a control group, makes similar sample, sample passes rate and diel number of stoppages contrast test.

Object	Make sample number	Sample passes rate (%)	The mould number of stoppages
				Blank group 1	10000	91.2	16
Blank group 2	10000	89.1	10
				Control group	10000	99.7	0

Visible, it is higher that diel of the present invention makes sample passes rate, and fault rate is lower.
