The structural representation of the pressing frock of the back axle bag longitudinal seam that Fig. 1 provides for the embodiment of the invention;
Fig. 2 is depression bar main body structure schematic diagram.
Among above Fig. 1-2:
The specific embodiment
The embodiment of the invention discloses a kind of pressing frock of back axle bag longitudinal seam, with under the prerequisite that guarantees smoothing back axle bag longitudinal seam quality, solution labor strength height, the problem that the working site noise pollution is big.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Please refer to Fig. 1, the pressing frock that the embodiment of the invention provides comprises support component 1 and platen parts 2.
Comprise depression bar body 31, spring 32 and nut 33 in the levelling depression bar 3.An end that passes the depression bar body 31 of strut kong 4 is provided with pressure head, and the other end then is thread segment.Nut 33 is set on the thread segment.Spring 32 and pressure head and base plate 11 or platen 21 location that offsets.
When the pressing frock of using present embodiment to provide, attach it on pneumatic, hydraulic pressure or the forcing press of other types.Support component 1 is installed on the workbench of forcing press, platen parts 2 is installed on the action post of forcing press, and the relevant position that the corresponding pending back axle in position of push-down head 12, seaming chuck 22 and levelling depression bar 3 is wrapped.After being placed into pending back axle bag on the support component 1, utilizing forcing press that platen parts 2 are pressed in back axle and wrap; In the process that platen parts 2 press down, the spring 32 in the levelling depression bar 3 is compressed, makes pending back axle bag being placed between support component 1 and the platen parts 2 by level; Afterwards, 12 pairs of back axles of seaming chuck 22 and push-down head are wrapped longitudinal seam warpage place and are contacted, and after through extruding and pressurize, warpage portion is smoothed, thereby has eliminated the buckling deformation that back axle is wrapped.
Compare with the existing mode of manpower smoothing that adopts, pressing frock provided by the present invention makes this work can utilize forcing press to finish, thereby has alleviated working strength of workers.Simultaneously, compare with manually knocking, the noise that produces in the forcing press course of work is littler, thereby has solved the big problem of working site noise pollution.
As can be seen; when being subjected to external pressure and making that deformation take place for spring 32, because the radius of first body of rod section 311 is greater than the radius of strut kong 4, even when the end face of first body of rod section 311 contacts with the end face of strut kong 4; spring 32 is just no longer further compressed, thus the spring 32 of protection.
Preferably, in the pressing frock that above-described embodiment provides, base plate 11 and platen 12 are provided with many group strut kongs 4, and levelling depression bar 3 is removably disposed in these strut kongs 4.
It will be appreciated by persons skilled in the art that the back axle bag for different model, its size can change.By many group strut kongs 4 are set, operating personnel can be installed to levelling depression bar 3 in these strut kongs 4 as required, can mate the back axle bag of different model so that flatten frock.
Same, seaming chuck 22 also can mate the back axle bag of different model by selecting the form of different installation positions with push-down head 12.
Concrete, in the platen frock that above-described embodiment provides, comprise four groups of levelling depression bars 3 in support component 1 and the platen parts 2 respectively.
Keep static in the smoothing process for back axle is wrapped in, further, in the pressing frock that above-described embodiment provides, also be provided with back axle bag backstay.
Back axle bag backstay is arranged on the base plate 11, and the position relation between many back axle bag backstays is determined according to the actual size of back axle bag.After being placed into pending back axle bag on the support component 1, many back axle bag backstays tighten it, prevent that pending back axle bag from rotating or being offset, thereby make it keep static in the smoothing process.
Preferably, also can be applicable to the back axle bag of different model in order to make back axle bag backstay, the same employing arranges a plurality of backstay installing holes, and back axle bag backstay is removably disposed in mode in the backstay installing hole.
In the process of smoothing back axle bag, in order to prevent that support component 1 and platen parts 2 are too approaching and cause the back axle bag to be damaged, on base plate 11, also be provided with height gag lever post 13.Understandable, the concrete highly also size with pending back axle bag of height gag lever post 13 is relevant, so it is not specifically highly limited.In the process of smoothing back axle bag, height gag lever post 13 makes and keeps the minimal security spacing between base plate 11 and the platen 21, causes the back axle bag to be damaged thereby avoid both too to approach.
Concrete, in the pressing frock that above-described embodiment provides, platen 21 is connected with forcing press by dismountable lining 23.
Another embodiment of the present invention also provides a kind of pressing equipment of back axle bag longitudinal seam.Concrete, comprising the pressing frock in forcing press and above-described embodiment, support component 1 is arranged on the workbench of forcing press, and platen parts 2 are arranged on the bottom of the column of forcing press.
Pressing equipment utilization forcing press provided by the present invention drives the pressing frock back axle bag is handled, and with the longitudinal seam of smoothing back axle bag, thereby has alleviated working strength of workers.Simultaneously, noise was less when the forcing press that utilizes invention to provide was smoothed, and had avoided noise that the working site is produced dysgenic problem.
Concrete, the forcing press in the above-mentioned platen equipment is hydraulic press or pneumatic press.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments herein.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
