Description

Punch for spring production

Technical Field

The utility model relates to a technical field of processing accessory, more specifically say, it relates to a drift is used in spring production.

Background

A spring is a mechanical part that works by elasticity. The part made of elastic material deforms under the action of external force and restores to the original shape after the external force is removed. Also used as a "spring". Typically made of spring steel.

When the spring is formed from a steel bar to a specific spring structure, a spring machine is required to bend, the spring machine realizes the bending of the spring through a punch in the production process, but the structure of the existing punch is complex, and the punch is easy to deform under stress, so that the punch needs to be replaced every three months.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a drift is used in spring production of rational in infrastructure simple, the practicality is strong, life is of a specified duration.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a drift is used in spring production, which comprises a body, the shaping has the contact that is used for the extrusion spring of buckling on the end of body, the breach that is used for the centre gripping spring has on the end of contact, the breach is the arc form, it is protruding to be equipped with the arc on the bottom of breach, on the unilateral of body end is arranged in to the contact, be equipped with on a lateral wall of body end and contact and strengthen the angle steel, with connect through the rib between another lateral wall of contact, it includes interconnect's right-angle square and set-square to strengthen the angle steel, the terminal surface of rib is arc form and radian and is 45.

Through adopting above-mentioned technical scheme, the breach on the contact realizes the application of force of buckling to the spring, and to avoid the breach that the breach is worn and torn to be bigger and bigger, so set up the arc arch on the bottom of breach, also can improve the compressive capacity of contact greatly moreover. In order to improve the structural strength and the pressure resistance of the contact, a reinforcing angle steel formed by a right-angle plate and a triangular plate and a reinforcing part formed in an arc shape are arranged between the contact and the end head. The reinforcing part can generate strong internal force when stressed, and the rigid load and the external force are greatly reduced.

The utility model discloses further set up to: the body end has two arc terminal surfaces, and these two radian terminal surfaces are holding surface and extension face respectively, and the terminal surface radian of holding surface is 35, and the terminal surface radian of extension face is 18.

By adopting the technical scheme, the structure of the arc-shaped end surface can further improve the pressure resistance of the contact, particularly the supporting surface, and the supporting surface is the extending end surface at the joint of the contact and the end head of the body, so the arc-shaped structure is adopted, and the rigid load resultant force generated between the contact and the body can be greatly reduced.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1.

The embodiment has the specific structure that: including body 1, the shaping has contact 2 that is used for the extrusion spring of buckling on the end of body 1, the breach 20 that is used for the centre gripping spring has on the end of contact 2, breach 20 is the arc form, be equipped with arc arch 6 on the bottom of breach 20, contact 2 is arranged in on the unilateral of 1 end of body, be equipped with on one side wall of 1 end of body and contact 2 and strengthen the angle steel, connect through rib 4 between another lateral wall of contact 2, strengthen the angle steel and include interconnect's square 31 and set-square 32, the terminal surface of rib 4 is arc form and radian and is 45.

The notch 20 on the contact 2 realizes the bending force application to the spring, so that the arc-shaped bulge 6 is arranged on the bottom of the notch 20 to avoid the worn notch 20 from being larger and larger, and the pressure resistance of the contact 2 can be greatly improved. In order to increase the structural strength and the pressure resistance of the contact 2, a reinforcing angle formed by a square 31 and a triangle 32 and a reinforcing portion 4 having an arc-shaped structure are provided between the contact 2 and the tip. The reinforcing part 4 can generate extremely strong internal force when stressed, and the rigid load and the external force are greatly reduced.

The end of the body 1 is provided with two arc end faces which are respectively a supporting face 51 and an extending face 52, the radian of the end face of the supporting face 51 is 35 degrees, and the radian of the end face of the extending face 52 is 18 degrees.

The structure of the arc-shaped end face can improve the pressure resistance of the contact 2 in one step, particularly the support face 51, and the support face 51 is an extension end face at the joint of the contact 2 and the end of the body 1, so the arc-shaped structure is adopted, and the rigid load resultant force generated between the contact 2 and the body can be greatly reduced.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
