Abstract
The present invention relates to a kind of gear rack molding die, shell is rushed including punch die and with what punch die was used cooperatively, it is described rush to be provided in shell rush benevolence, it is characterised in that：Mode is provided in the punch die, the gear rack type hole for penetrating through the mode is provided in the mode, the threaded hole for penetrating into the mode is provided at the top of the punch die, the screw pitch of the gear rack type hole is identical with the screw pitch of the threaded hole, is additionally provided in the punch die and the gear rack type hole and the matched adjusting bolt of the screw thread.The present invention can adjust the active length of gear rack type hole by the precession and back-out of adjusting bolt, to adapt to the production needs of different length gear rack.
Description
Technical field
The present invention relates to gear rack former fields, and in particular to a kind of gear rack molding die.
Background technology
Gear rack is that one kind of full thread stud is commonly called as, and is a kind of common fastener.At present, cooling formation technic is widely used
Carry out the processing and forming of gear rack, both by specific punch die by bar punch process into required gear rack.
Mold is all to be designed to process according to retaining element fixed dimension, and mold is typically unadjustable when in use
's.Most of existing gear rack molding die can only correspond to the gear rack of a model, and producing different gear racks needs to manufacture mostly pair
Gear rack molding die.This certainly will reduce gear rack production efficiency, add gear rack production cost.
Therefore, how designing one kind and adapting to the molding mold of different model gear rack is that those skilled in the art are urgently to be resolved hurrily
A problem.
The content of the invention
The technical problems to be solved by the invention are for the prior art, and providing one kind has the function of longitudinally adjust, can fit
Answer the molding gear rack molding die of different length gear rack.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of gear rack molding die, including punch die with
And rush shell with what punch die was used cooperatively, it is described rush to be provided in shell rush benevolence, it is characterised in that：Mode is provided in the punch die,
The gear rack type hole for penetrating through the mode is provided in the mode, the screw thread for penetrating into the mode is provided at the top of the punch die
Hole, the screw pitch of the gear rack type hole is identical with the screw pitch of the threaded hole, is additionally provided in the punch die and the gear rack type hole
The adjusting bolt closed with the corresponding threaded holes.The work that gear rack type hole can be adjusted by the precession and back-out of adjusting bolt is grown
Degree, makes the mold have the function of longitudinally adjust, to adapt to the production needs of different length gear rack.
As an improvement, the adjusting bolt includes preceding thread portion, connecting portion and rear thread portion, the preceding thread portion and described
Gear rack type hole is engaged, the connecting portion connection preceding thread portion and rear thread portion, the rear thread portion and the corresponding threaded holes
It closes；The gear rack type hole diameter is less than the screw thread bore dia.This structure can guarantee that rear thread portion and threaded hole bear bigger
Pressure, with reduce because punching press and caused by gear rack type hole damage.
Preferably, the preceding thread portion is equal to the length of the threaded hole plus the length of the connecting portion, after described
Threaded portion is equal to the length of the threaded hole plus the length of the connecting portion.Such setting can make the preceding spiral shell in adjusting bolt
Line portion and rear thread can be screwed into bottom with gear rack type hole and threaded hole respectively or screw out simultaneously simultaneously, and adjusting is facilitated to carry out longitudinal tune
Section.
Preferably, the length in the preceding thread portion is less than the length of the gear rack type hole.Ensure that preceding thread portion will not be because
Gear rack type hole is passed completely through to be long, causes to be unable to punching press.
Compared with prior art, the advantage of the invention is that：Pass through the gear rack type hole of setting, threaded hole and adjusting bolt
Cooperation enables adjusting bolt precession and back-out on punch die, carries out longitudinally adjust, changes effective active length of gear rack type hole,
To adapt to the shaping of different length gear rack.
Description of the drawings
Fig. 1 is the structure diagram of the embodiment of the present invention；
Fig. 2 is the exploded structure diagram of the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with attached drawing embodiment.
As shown in Fig. 1~2, the gear rack molding die of the present embodiment includes punch die 3 and rushes shell with what punch die was used cooperatively
1, it rushes in shell 1 to be provided with and rushes benevolence 2, punching press is carried out to gear rack bar by rushing benevolence 2.Mode 4 is provided in punch die 3, among mode 4
The gear rack type hole 41 of entire mode 4 is provided through, 3 top of punch die is provided with the threaded hole 31 for penetrating into mode 4, wherein gear rack
The screw pitch of type hole 41 is identical with the screw pitch of threaded hole 31.It is additionally provided in punch die 3 and is engaged with gear rack type hole 41 and threaded hole 31
Adjusting bolt 5, adjusting bolt include preceding thread portion 51, connecting portion 52 and rear thread portion 53, wherein, preceding thread portion 51 and gear rack
Type hole 41 is engaged, and connecting portion 52 connects preceding thread portion 51 and rear thread portion 53, rear thread portion 53 are engaged with threaded hole 31.
In addition, 41 diameter of gear rack type hole is less than 31 diameter of threaded hole, when ensureing punching press, rear thread portion 53 and threaded hole 31 are held
By the pressure of bigger, to reduce to damage caused by gear rack type hole 41；Preceding thread portion 51 is equal to spiral shell plus the length of connecting portion 52
The length of pit 31, rear thread portion 53 are equal to the length of threaded hole 31 plus the length of connecting portion 52, facilitate the tune of adjusting bolt
Section；The length in preceding thread portion 51 is less than the length of gear rack type hole 41, meets actual punching press requirement.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art,
Without departing from the structure of the invention, various modifications and improvements can be made, these all do not interfere with implementation of the present invention
Effect and practical applicability.
