Abstract
A spacing type elastic device comprises a flange type bolt, a spring and an adjusting rod, wherein the spring is installed at the top end of the adjusting rod through the flange type bolt. The spacing type elastic device has the advantages that the flange type bolt is adopted to replace traditional double bolts, elasticity of the elastic device does not need to be adjusted when the elastic device is installed again after being dismantled, and maintenance and usage are convenient.
Description
Technical field
The utility model relates to a kind of limit-type elastic device, especially is applied in the limit-type elastic device on the motor iron core progressive die.
Background technology
Along with the development of society, increasing enterprise begins to introduce the progressive die project.Because a lot of enterprises contact progressive die first, require in design convenient for maintaining use of progressive die, more hommization.
Progressive die has a lot of elastic devices: such as pilot pin device, misdelivery checkout gear, buoyant device, stack-press device.The elastic device of foregoing description is general to adopt two plug screws to fix, and sees shown in the figure one.Because elastic device plug screw fixed position is by manually-operated, often cause the elastic force of elastic device inconsistent, more crucial is after the elastic force of elastic device is adjusted, in case mould needs repairing, the plug screw of dismounting resets when readjusting elastic force again, and the difference on the manually-operated technical ability will have influence on the uniformity of elastic device elastic force, mainly be reflected in following several respects: 1, pilot pin device elastic force is not enough, pilot pin can't accurately lead, and does not enter the billot correcting toward contact, has begun retraction; Elastic force is too large, and pilot pin is correcting by force, easily causes the correcting bore deformation, the band material, and product is defective, and mould can not normally be produced; 2, misdelivery checkout gear elastic force is not enough, and the misdelivery test pin easily bounces back, and causes frequent misdelivery; Elastic force is too large, and the misdelivery test pin becomes drift and participates in stamping-out, does not play the misdelivery detection effect; 3, buoyant device elastic force is not enough, and normal buoyant in feeding process affects billot and sends to; Elastic force is too large, and buoyant is sold to toward with the distortion of billot top, causes product size defective; 4, the stack-press device elastic force is not enough, moulding can't be laminated a little eject to laminate die, causes the band material; Elastic force is too large, easily moulding is laminated a top distortion, can not satisfy product and laminate.
Can find out from foregoing description, a lot of elastic devices of progressive die the inside have higher requirements to the elastic force of spring, and two plug screw constant depth of elastic device clearly indicate, can't be spacing, brought inconvenience to the normal use of mould.
Summary of the invention
In order easily to cause the inconsistent problem of elastic force owing to human factor in the elastic device installation process that solves present progressive die, the utility model proposes the inconsistent limit-type elastic device of a kind of elastic force of avoiding human factor to cause.
Limit-type elastic device described in the utility model is characterized in that: comprise flange-type bolt, spring, adjusting rod, described spring is installed in the top of described adjusting rod by the flange-type bolt.
Described spring is Rectangular Spring.
Described limit-type elastic device is arranged on the pilot pin device of electric machine iron core, misdeliver checkout gear, buoyant device, the stack-press device.
During use, adjust the elastic force of spring after, with the flange-type bolt spring is fixed on the adjusting rod that is installed in advance on pilot pin device, misdelivery checkout gear, buoyant device, the stack-press device.
The beneficial effects of the utility model are: adopt the flange-type bolt to replace traditional two bolts, the elastic force that does not need to adjust elastic device is installed after the dismounting again, keep in repair easy to use.
