Abstract
The utility model relates to a kind of gear rack mould, comprise punch die and with punch die with the use of rush shell, described rush in shell to be provided with rush benevolence, it is characterized in that: in described punch die, be provided with die, the gear rack nibs of through described die is provided with in described die, described punch die top is provided with the screwed hole penetrating into described die, and the pitch of described gear rack nibs is identical with the pitch of described screwed hole, is also provided with the adjusting bolt matched with described gear rack nibs and described screw thread in described punch die.The utility model, can regulate the active length of gear rack nibs, to adapt to the need of production of different length gear rack by precession and the back-out of adjusting bolt.
Description
Technical field
The utility model relates to gear rack former field, is specifically related to a kind of gear rack mould.
Background technology
Gear rack is that the one of full thread stud is commonly called as, and is a kind of conventional securing member.At present, widely use the processing and forming that cooling formation technic carries out gear rack, both by specific punch die by bar punch process become needed for gear rack.
Mould is all according to retaining element fixed dimension design processing, and mould is generally all uncontrollable in use.Existing gear rack mould great majority can only the gear rack of a corresponding model, and producing different gear racks needs to manufacture how secondary gear rack mould.This certainly will reduce gear rack production efficiency, adds gear rack production cost.
Therefore, how designing a kind of shaping mould of different model gear rack that can adapt to is those skilled in the art's problems urgently to be resolved hurrily.
Utility model content
Technical problem to be solved in the utility model is for prior art, provides one to have longitudinal regulatory function, can adapt to the gear rack mould that different length gear rack is shaping.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of gear rack mould, comprise punch die and with punch die with the use of rush shell, described rush in shell to be provided with rush benevolence, it is characterized in that: in described punch die, be provided with die, the gear rack nibs of through described die is provided with in described die, described punch die top is provided with the screwed hole penetrating into described die, the pitch of described gear rack nibs is identical with the pitch of described screwed hole, is also provided with the adjusting bolt of closing with described gear rack nibs and described corresponding threaded holes in described punch die.By the precession of adjusting bolt with screw out the active length that can regulate gear rack nibs, this mould is made to have longitudinal regulatory function, to adapt to the need of production of different length gear rack.
As improvement, described adjusting bolt comprises preceding thread portion, connecting portion and rear thread portion, and described preceding thread portion and described gear rack nibs match, and described connecting portion connects preceding thread portion and rear thread portion, and described rear thread portion and described corresponding threaded holes close; Described gear rack type hole diameter is less than described screwed hole diameter.This structure can ensure that rear thread portion and screwed hole bear larger pressure, to reduce the damage caused gear rack nibs because of punching press.
As preferably, described preceding thread portion adds that the length of described connecting portion equals the length of described screwed hole, and described rear thread portion adds that the length of described connecting portion equals the length of described screwed hole.Arranging like this can make the preceding thread portion in adjusting bolt and rear thread be screwed into the end with gear rack nibs and screwed hole respectively simultaneously or to screw out simultaneously, facilitates adjustment to carry out longitudinal adjustment.
As preferably, the length in described preceding thread portion is less than the length of described gear rack nibs.Ensure that preceding thread portion can not pass completely through gear rack nibs because of long, causing can not punching press.
Compared with prior art, the utility model has the advantage of: by the cooperation of the gear rack nibs that arranges, screwed hole and adjusting bolt, make adjusting bolt can precession and back-out on punch die, carry out longitudinal adjustment, change effective active length of gear rack nibs, shaping to adapt to different length gear rack.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the exploded structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Fig. 1 ~ 2, the gear rack mould of the present embodiment comprise punch die 3 and with punch die with the use of rush shell 1, rushing in shell 1 to be provided with and rush benevolence 2, carrying out punching press by rushing benevolence 2 pairs of gear rack bars.Be provided with die 4 in punch die 3, be provided with the gear rack nibs 41 running through whole die 4 in the middle of die 4, punch die 3 top is provided with the screwed hole 31 penetrating into die 4, and wherein the pitch of gear rack nibs 41 is identical with the pitch of screwed hole 31.The adjusting bolt 5 matched with gear rack nibs 41 and screwed hole 31 is also provided with in punch die 3, adjusting bolt comprises preceding thread portion 51, connecting portion 52 and rear thread portion 53, wherein, preceding thread portion 51 and gear rack nibs 41 match, connecting portion 52 connects preceding thread portion 51 and rear thread portion 53, and rear thread portion 53 matches with screwed hole 31.
In addition, gear rack nibs 41 diameter is less than screwed hole 31 diameter, and when ensureing punching press, rear thread portion 53 and screwed hole 31 bear larger pressure, to reduce the damage caused gear rack nibs 41; Preceding thread portion 51 adds that the length of connecting portion 52 equals the length of screwed hole 31, and rear thread portion 53 adds that the length of connecting portion 52 equals the length of screwed hole 31, facilitates the adjustment of adjusting bolt; The length in preceding thread portion 51 is less than the length of gear rack nibs 41, meets actual punching press requirement.
Above-described is only preferred embodiment of the present utility model, should be understood that for a person skilled in the art, under the prerequisite not departing from the utility model structure, can also make some distortion and improvement, these all can not affect effect and the practical applicability of the utility model enforcement.
