Abstract
The utility model relates to the technical field of screw sleeves and particularly relates to a sleeve composite member for producing a long shank screw, comprising a safety sleeve and a punch bar, wherein the punch bar is arranged in the safety sleeve; the sleeve composite member also comprises an ejector rob arranged at the rear of the punch bar; the safety sleeve is provided with a channel matched with the ejector rob in shape; the punch bar is matched with the channel; and the ejector rod pushes the punch bar to movably stretch in the channel. The safety sleeve provided by the utility model is used for completely sleeving the ejector rod tightly, the punch bar is matched with the channel, and thus, the diameter of the punch bar is indirectly increased, the contact area between the punch bar and the safety sleeve is increased, the supporting force of the punch bar is greatly increased to ensure that the punch bar is not easy to be blasted to be cracked, the sleeve composite member can be used for producing products with longer specifications or larger stress, and a machine stand is safer and more stable in operating and running when overlong-specification products are produced.
Description
Technical field
The utility model relates to the screw nut technical field, relates in particular to a kind of sleeve combination part of producing the stock screw.
Background technology
Screw is to utilize the inclined-plane circular rotating of object and physics and the mathematical principle of frictional force, the instrument of fastening implements parts by easy stages, it is indispensable industrial necessity in the daily life, of a great variety, main purpose is industrial product to be formed be fixed as one, and the quality of screw and the mould of its production, technique are closely bound up.
At present, produce over-long specification or the stressed larger screw of mould, bolt product in the industry, usually have and adopt the condom tubular construction to strengthen and to support punching excellent stressed, but the condom tubular construction that generally adopts at present can not entangle the punching rod well firm, punching rod only has in safe sleeve pipe and rushes excellent base and contact with safe sleeve pipe, it is unsettled rushing excellent stock position, do not contact with safe sleeve pipe, if resistance is bigger than normal a little, rush excellent bar section and may burst because lacking support force, damage board or mould.Therefore, safe sleeve pipe remains to be improved.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art, and a kind of sleeve combination part of producing the stock screw is provided, and it is simple in structure, reasonable in design, and safe sleeve pipe can entangle the punching rod fully firm, greatly improve the support force of punching rod, guarantee that board processing is safer, more stable.
The utility model is realized by following technology.
A kind of sleeve combination part of producing the stock screw, comprise safe sleeve pipe and punching rod, described punching rod is arranged at the inside of described safe sleeve pipe, described sleeve combination part also comprises push rod, described push rod is arranged at the rear of described punching rod, described safe sleeve pipe offers the passage with the form fit of described push rod, and described punching rod cooperates with described passage, the described punching of described push rod promotion excellent in described passage movable telescopic.
Wherein, described punching rod comprises bar section and bottom, and described bar section is arranged at the top of described bottom, and described safe sleeve pipe stretches out in described bar section.
Wherein, the middle part of described safe sleeve pipe is provided with endoporus, and described bar section and described endoporus are connected.
Wherein, the form fit of described bottom and described passage, described bottom and described passage are slidingly connected.
Wherein, the top of described safe sleeve pipe is provided with chamfering.
The beneficial effects of the utility model are: a kind of sleeve combination part of producing the stock screw, comprise safe sleeve pipe and punching rod, described punching rod is arranged at the inside of described safe sleeve pipe, described sleeve combination part also comprises push rod, described push rod is arranged at the rear of described punching rod, described safe sleeve pipe offers the passage with the form fit of described push rod, and described punching rod cooperates with described passage, the described punching of described push rod promotion excellent in described passage movable telescopic.The cross section of push rod of the present utility model is flower shape, can push rod be designed to according to the needs of actual production the colored shape of various shape, applied widely, simultaneously, with the channels designs one-tenth of safe sleeve pipe and the colored shape of the form fit of push rod, push rod thereby fully contact with safe sleeve pipe, make safe sleeve pipe entangle push rod fully firm, and the punching rod cooperates with passage, quite indirectly increased and rushed excellent diameter, increased the contact area of punching rod and safe sleeve pipe, greatly improved the support force of punching rod and be difficult for bursting, make the utility model can produce before more long size or stressed larger product, board operation and move safer when producing the over-long specification product, more stable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is decomposing schematic representation of the present utility model.
Reference numeral comprises:
1-safe sleeve pipe, 11-passage, 2-punching rod, 21-bar section, 22-bottom, 3-push rod.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of sleeve combination part of producing the stock screw of the present embodiment, comprise safe sleeve pipe 1 and punching rod 2, described punching rod 2 is arranged at the inside of described safe sleeve pipe 1, described sleeve combination part also comprises push rod 3, and described push rod 3 is arranged at the rear of described punching rod 2, and described safe sleeve pipe 1 offers the passage 11 with the form fit of described push rod 3, described punching rod 2 cooperates with described passage 11, and described push rod 3 promotions described punching excellent 2 is at described passage 11 interior movable telescopics.The cross section of push rod 3 of the present utility model is flower shape, can push rod 3 be designed to according to the needs of actual production the colored shape of various shape, applied widely, simultaneously, the passage 11 of safe sleeve pipe 1 is designed to colored shape with the form fit of push rod 3, push rod 3 thereby fully contact with safe sleeve pipe 1, make safe sleeve pipe 1 entangle push rod 3 fully firm, and punching rod 2 cooperates with passage 11, quite indirectly increased the diameter of punching rod 2, increased the contact area of punching rod 2 with safe sleeve pipe 1, greatly improved the support force of punching rod 2 and be difficult for bursting, make the utility model can produce before more long size or stressed larger product, board operation and move safer when producing the over-long specification product, more stable.
In the present embodiment, described punching rod 2 comprises bar section 21 and bottom 22, described bar section 21 is arranged at the top of described bottom 22, described safe sleeve pipe 1 stretches out in described bar section 21, the middle part of described safe sleeve pipe 1 is provided with endoporus, described bar section 21 and described endoporus are connected, the form fit of described bottom 22 and described passage 11, and described bottom 22 is slidingly connected with described passage 11.Bar section 21 and the bottom 22 of punching rod 2 are one-body molded; the diameter of the bar section 21 of the diameter specific impulse rod 2 of the endoporus of safe sleeve pipe 1 is slightly large; bar section 21 can insert in the endoporus and slide; be convenient to it and stretch out safe sleeve pipe 1; and then blank headed in the master mold; and bar section 21 because of with the cooperating of endoporus; avoid it to be difficult to touch the inwall of safe sleeve pipe 1 and be vacant state; therefore indirectly increased the diameter of punching rod 2; greatly improved the holding capacity of punching rod 2; how movable in the inside of safe sleeve pipe 1 regardless of rushing rod 2, can both give and rush excellent 2 larger support forces, play the effect of protection punching rod 2.
