Abstract
The utility model relates to a die balance protection device which comprises a spring sleeved with a spring protection hood. A through hole is formed in the top of the spring protection hood, an elastic ejection block is mounted in the through hole, a boss extends from the bottom of the spring protection hood, the boss is connected with a lower die plate through a plurality of screws, and the top of the elastic ejection block connected with an upper die plate in abutting mode. The die balance protection device is reasonable in structure, simple and convenient to operate and mount, safe and reliable, and strong in universality. The die balance protection device is mounted between the upper die plate and the lower die plate of a die, so that the unbalance loading problem of the die in the stamping process is effectively avoided, front-back and left-right size consistence of a product in the stamping process is guaranteed, product machining quality is improved, the die is protected, and the service life of the die and the service life of a punch press are prolonged.
Description
Technical field
The utility model relates to the mould structure technical field, and is especially a kind of for the mould balanced protection device on air-conditioner fin.
Background technology
Air-conditioner fin die is when normal operation; patrix need to be fixed on slider of punch; then open closed stamping products ceaselessly; in actual mechanical process; owing to having in mould in a lot of submodules, spring is arranged; so often can cause mould that the front and back unbalance loading in use occurs; in case mould is unbalance loading in punching course; can cause the product left-right and front-back of rushing out all inconsistent; affect product processing quality; make product defective, long-term use also can make punch press impaired, shortens die life.
The utility model content
Unbalance loading easily occurs for mould in above-mentioned existing production technology in the applicant; cause product processing quality poor; shorten the shortcomings such as die life; a kind of mould balanced protection device rational in infrastructure is provided; thereby make punch press after installation mold, can keep balance all around during continuous punching, make mould can stamp out the good product of dimensional uniformity; improve product processing quality, extend simultaneously the service life of mould and punch press.
The technical scheme that the utility model adopts is as follows:
A kind of mould balanced protection device, comprise spring, and the outer cover of described spring has the spring protection cover, the top of described spring protection cover has through hole, the bullet jacking block is installed in described through hole, and the bottom of described spring protection cover is extended with boss, and described boss place is connected with lower bolster by a plurality of screws; The top of described bullet jacking block and cope match-plate pattern butt.
As further improvement in the technical proposal:
The internal face of the through hole that open at the outer circumference surface of bullet jacking block and the top of spring protection cover adopts matched in clearance;
Between the outer circumference surface of described spring and spring protection cover internal face, monolateral distance is 0.5mm-1mm.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, and operation and simple installation are safe and reliable, highly versatile.By installation mold balanced protection device between the cope match-plate pattern at mould and lower bolster; prevent that effectively mould from the problem of unbalance loading occurring in punching course; the product uniformity of size all around while guaranteeing punching press; improve product processing quality; protect simultaneously mould itself, extended the service life of mould and punch press.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is application drawing of the present utility model.
Wherein: 1, play jacking block; 2, spring protection cover; 3, spring; 4, boss; 5, screw; 6, cope match-plate pattern; 7, lower bolster.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As depicted in figs. 1 and 2, the mould balanced protection device of the present embodiment, comprise spring 3, the outer cover of spring 3 has spring protection cover 2, the top of spring protection cover 2 has through hole, be equipped with in through hole and play jacking block 1, the bottom of spring protection cover 2 is extended with boss 4, and boss 4 places are connected with lower bolster 7 by a plurality of screws 5; Play top and cope match-plate pattern 6 butts of jacking block 1.
The through-hole wall face that open at the outer circumference surface of bullet jacking block 1 and the top of spring protection cover 2 adopts matched in clearance.
Between the outer circumference surface of spring 3 and spring protection cover 2 internal faces, monolateral distance is 0.5mm-1mm.
As shown in Figure 3, in actual use procedure, complete as follows installation.
At first will play pack into the top of spring protection cover 2 of jacking block 1, the spring 3 of then packing in spring protection cover 2, next be fixed on its integral body on the lower bolster 7 of mould by screw 5, play top and cope match-plate pattern 6 butts of jacking block 1.This mounting means is simple and reliable, and safety durable, efficiently solves the problem of the unbalance loading of mould in punch press uses.
The decrement of spring 3 described in the utility model is selected according to practical application.
For example: spring 3 is spring (the diameter 40mm of SWH40-100; length 100mm); the initial length that spring 3 is placed in spring protection cover 2 is 98mm; namely the initial compression amount is 2mm; when closed to mould, the length of spring has become 85mm, is equivalent to compress 15mm, and spring 3 permission maximum compressibility are 21mm; namely can be compressed to length be 79mm to this spring, and this spring 3 also has the compressible amount of 6mm.At this moment, the spring protection cover 2 that adopts is 118mm with the overall length that plays jacking block 1, and the length that plays jacking block 1 is 20mm.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
