Abstract
The invention discloses a kind of forming frocks of tension spring drag hook, including die shank, pressure head, forming blocks, bottom plate, pin and locating piece；Wherein forming blocks and locating piece are fixed by a pin on bottom plate, and pressure head is fixed in forming blocks, and die shank is fixed on pressure head；When work, the tension spring for needing to process before the molding of drag hook drag hook is placed in locating piece, punching machine presses die shank, and band dynamic head moves up and down, and the inclined-plane of pressure head extrudes drag hook by separated steel wire, produces drag hook tension spring after molding.The present invention improves the dimensional stability for the tension spring part produced, and improves work efficiency.
Description
One, technical field
The present invention relates to spring manufacturing technology field, especially a kind of forming frock of tension spring drag hook.
Two, background technique
Tension spring is subject to the helical spring of axial tension.Tension spring is generally all manufactured with circular section material, is being not subject to load
When, it is typically all between the circle and circle of extension spring and tight very close to each other.Tension spring is suitable for the building rings such as high/low temperature, corrosion-resistant
Border, material mainly include stainless steel spring line, carbon steel wire, oil hardening tempering alloy spring line, high/low temperature alloy spring line etc..
Currently, in process of production, for the manufacture of tension spring drag hook mostly use manually perpendicular seedling or large-scale automatic torsion machine at
Type can only just take the method for artificial perpendicular seedling to produce the enterprise of no large-scale automatic torsion machine, direct labor's labor intensity
Greatly, low efficiency, different direct labors will cause product size control inconsistent, and seriously affect product quality.
Three, summary of the invention
The purpose of the present invention is to provide a kind of forming frock of tension spring drag hook, the production for being able to solve tension spring drag hook is asked
Topic, guarantees the dimensionally stable of tension spring part produced, drag hook shape is consistent.
The technical solution of existing the object of the invention are as follows: a kind of forming frock of tension spring drag hook, including die shank, pressure head, at
Type block, bottom plate, pin and locating piece；
The forming blocks and locating piece are fixed by a pin on bottom plate, and pressure head is fixed in forming blocks, and die shank is fixed
On pressure head；
When work, the tension spring for needing to process before drag hook molding is placed in locating piece, punching machine presses die shank, on band dynamic head
The inclined-plane of lower movement, pressure head extrudes drag hook by separated steel wire, produces drag hook tension spring after molding.
Further, the pressure head is connected with forming blocks by sliding rail, and pressure head can move up and down relative to forming blocks.
Further, the locating piece can be replaced, and produce different tension spring drag hooks.
Further, the die shank is connect with punching machine, is moved up and down by punched tape dynamic model handle.
The beneficial effects of the present invention are: the power of punching machine is utilized to operate in (1), and it is easy to operate, alleviate operator's
Physical demands improves work efficiency；(2) guarantee that the dimensionally stable for the tension spring part produced is consistent, drag hook shape is consistent, changes
Product quality has been apt to it, has avoided scale error caused by manual operation, has avoided product size caused by different direct labors
Inconsistent situation；(3) it using traditional reliable structure, is easy to make, it is easy to maintain；(4) it is different that locating piece processing can be replaced
The tension spring drag hook of specification.
Four, Detailed description of the invention
Fig. 1 is the structural schematic diagram of the forming frock of tension spring drag hook of the present invention.
Five, specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that, term " on ", "lower", "front", "rear", "left", "right", "top",
The orientation or positional relationship of the instructions such as "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, merely to just
In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation, therefore be not considered as limiting the invention.
In conjunction with Fig. 1, a kind of forming frock of tension spring drag hook of the present invention, including die shank 1, pressure head 2, forming blocks 3, bottom plate 4, pin
Nail 5 and locating piece 6；
The forming blocks 3 and locating piece 6 are fixed on bottom plate 4 by pin 5, and pressure head 2 is fixed in forming blocks 3, mould
Handle 1 is fixed on pressure head 2；
When work, the tension spring 8 for needing to process before drag hook molding is placed in locating piece 6, punching machine presses die shank 1, band dynamic pressure
First 2 move up and down, and the inclined-plane of pressure head 2 extrudes drag hook by separated steel wire, produce drag hook tension spring 7 after molding.
Further, the pressure head 2 is connected with forming blocks 3 by sliding rail, and pressure head 2 can be done up and down relative to forming blocks 3
Movement.
Further, the locating piece 6 can be replaced, and produce different tension spring drag hooks.
Further, the die shank 1 is connect with punching machine, is moved up and down by punched tape dynamic model handle 1.
In summary, a kind of forming frock of tension spring drag hook of the present invention, is utilized the power of punching machine to operate, operation side
Just, the physical demands for alleviating operator, improves work efficiency；Guarantee that the dimensionally stable for the tension spring part produced is consistent,
Drag hook shape is consistent, improves product quality, avoids scale error caused by manual operation, avoids different direct labors
Caused by the inconsistent situation of product size；Using traditional reliable structure, it is easy to make, it is easy to maintain；Locating piece can be replaced
Process the tension spring drag hook of different size.
For those skilled in the art, it is possible to understand that without departing from the principles and spirit of the present invention may be used
To carry out a variety of change, modification, replacement and modification to these embodiments, the scope of the present invention is by appended claims and its is equal
Object limits.
