Detailed description of the invention
By describing technology contents of the present utility model in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
The design of the utility model most critical is: damping blanking device adopts fluid damping to cushion blanking retaining screw, the wearing and tearing that frictional damping causes can be avoided, thus raising life of product, the operation kinetic energy of workpiece can also be offset by the part kinetic energy that syn-collision does not utilize workpiece to run simultaneously.
Refer to Fig. 3 and Fig. 4, a kind of damping blanking device of stamping strip part, comprise patrix 205 and counterdie 201, the peripheral region described counterdie 201 being positioned at the punching press station of blank 101 is provided with many group damping blanking assemblies 301, and described damping blanking assembly 301 comprises damping blanking assembly 303 and fluid storage space 302; Described damping blanking assembly 303 comprises blanking retaining screw 304, and described blanking retaining screw 304 is arranged in counterdie 201; Described fluid storage space 302 is located in counterdie 201, is filled with fluid damping medium in fluid storage space 302; Blanking retaining screw 304 is stretched out from the upper surface of counterdie 201 through fluid storage space 302.
From foregoing description, the beneficial effects of the utility model are: after blank enters punching press station, under the effect of inertia, warp collides with the blanking retaining screw of damping blanking assembly, thus the operation kinetic energy of absorptive hair blank, the kinetic energy of its collision rift is offset in the damped motion of blanking retaining screw in fluid damping medium, on the one hand can avoid or reduce the resilience of blank, can reduce on the other hand or collision free to the injury at blank edge; Meanwhile, employing fluid damping medium is conducive to blanking retaining screw and blank realizes multiple impacts, is offset the operation kinetic energy of workpiece by the part kinetic energy that syn-collision does not utilize workpiece to run; Avoid the wearing and tearing adopting frictional damping to cause simultaneously; This device is easy to manufacture, and interchangeability is good, easy to use.
Further, described damping blanking assembly 303 also comprises reset portion 305, and described reset portion 305 to be located in the installing hole 313 bottom described counterdie 201 and to be positioned at the below in described fluid storage space 302, and the lower end of described blanking retaining screw 304 is connected with reset portion 305.
Further, with reference to Fig. 9 to Figure 12, described reset portion 305 comprises fixed part 307 and flexible connecting member 306, described fixed part 307 is fixed in the installing hole 313 in described counterdie 201, the lower end that one end of described flexible connecting member 306 is installed on fixed part 307, the other end is connected to described blanking retaining screw 304.
Preferably, the flexible connecting member 306 in Fig. 9 and Figure 10 is spring, and the flexible connecting member 306 in Figure 11 and Figure 12 is resilient sleeve, and spring or resilient sleeve are all that one end is socketed on fixed part 306, and the other end is socketed in the lower end of blanking retaining screw 304.
Seen from the above description, adopt flexible connecting member to realize parts as what realize reset function, structure is simple, easy for installation and cheap; Particularly, after blanking retaining screw is promoted by blank, flexible connecting member produces distortion, and the impact that blanking retaining screw receives from blank is absorbed in fluid damping medium, and blanking retaining screw is conducive to repeatedly moving under the effect of flexible connecting member.
Further, with reference to Figure 13 and Figure 14, described reset portion 305 comprises a spatial accommodation 317, and the lower end of described blanking retaining screw 304 is provided with spherical termination 309, and the spherical termination 309 of blanking retaining screw 304 is installed in described spatial accommodation 317.
Seen from the above description, spherical termination can be rotated in spatial accommodation, thus blanking retaining screw can be moved in installing hole, and when patrix is descending, blanking retaining screw upper end realizes mobile and reset function under the effect at the reset position 314 of patrix reset components 204.
Further, with reference to Figure 15 and Figure 16, described reset portion 305 comprises support spring 310 and supporting sephere 318, the lower end of described blanking retaining screw 304 is provided with shoulders 308, described support spring 310 is installed in described installing hole 313, described supporting sephere 318 is located on support spring 310, and the shoulders 308 of blanking retaining screw 304 is located on supporting sephere 318.
Seen from the above description, when blanking retaining screw is promoted backward by blank, blanking retaining screw presses down supporting sephere by shoulders, supporting sephere presses down support spring makes support spring be compressed, reset upwards jack-up supporting sephere, supporting sephere of Compress Spring supports shoulders, thus is conducive to blanking retaining screw and repeatedly moves.
Comprehensive above-mentioned multiple scheme with reset portion is known, the beneficial effect arranging reset portion is: for quick feeding, resilience is inevitable, majority needs multiple impacts, and blanking retaining screw bottom be provided with reset portion after by with the coordinating of the backgauge retaining assembly that counterdie is arranged, be conducive to the multiple impacts realizing blank.For the blank that large momentum runs, blanking retaining screw can design by little striking momentum, blanking retaining screw and blank collision rift move forward fast and to rebound with mold component collision rift, bounce-back after and blank again collide, blank and blanking retaining screw are slowed down gradually through multiple impacts, thus the operation kinetic energy of blank pieces is offset by the part kinetic energy that syn-collision does not utilize blank to run, blanking is stablized, little to the injury of workpiece.
Further, described fluid storage space 302 also comprises overflow launder 311 and backup fluid storage area 312, described overflow launder 311 to be located in described counterdie 201 and to be communicated with the top in fluid storage space 302, and the below in fluid storage space 302 is located in described backup fluid storage area 312.Spatial joint clearance between described backup fluid storage area 312 and described damping blanking assembly 303 is larger.
