Detailed description of the invention
The embodiment of the invention discloses a kind of pressing frock of back axle bag longitudinal seam, with under the prerequisite ensureing smoothing back axle bag longitudinal seam quality, solve the problem that labor strength is high, working site noise pollution is large.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, the pressing frock that the embodiment of the present invention provides comprises support component 1 and platen parts 2.
Support component 1 comprises base plate 11, levelling depression bar 3 and push-down head 12.Base plate 11 is provided with multiple strut kong 4, levelling depression bar 3 is arranged in strut kong 4, and push-down head 12 is arranged on the end face of base plate 11.
Platen parts 2 comprise platen 21, levelling depression bar 3 and seaming chuck 22.Platen 21 is provided with equally multiple strut kong 4, levelling depression bar 3 is arranged in strut kong 4, and seaming chuck is arranged on the bottom surface of platen.
Levelling depression bar 3 comprises depression bar body 31, spring 32 and nut 33.One end through the depression bar body 31 of strut kong 4 is provided with pressure head, and the other end is then thread segment.Nut 33 is set on thread segment.Spring 32 and pressure head and base plate 11 or platen 21 offset and locate.
When the pressing frock using the 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 are installed on the action post of forcing press, and make the relevant position that the corresponding pending back axle in the position of push-down head 12, seaming chuck 22 and levelling depression bar 3 is wrapped.After pending back axle bag is placed on support component 1, utilizes 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 levelling depression bar 3 is compressed, and makes pending back axle bag be placed between support component 1 and platen parts 2 by level; Afterwards, seaming chuck 22 and push-down head 12 pairs of back axles are wrapped longitudinal seam warpage place and are contacted, and after extruding and pressurize, warpage portion is leveling, thus eliminates the buckling deformation that back axle wraps.
Compared with the mode of smoothing with existing employing manpower, pressing frock provided by the present invention makes this work that forcing press can be utilized to complete, thus alleviates the labour intensity of workman.Meanwhile, compared with manually knocking, the noise produced in the forcing press course of work is less, thus solves the large problem of working site noise pollution.
Produce excessive deformation in order to avoid the spring 32 in levelling depression bar 3 and damage, depression bar body 31 is provided with position limiting structure.As shown in Figure 2, depression bar body 31 includes successively pressure head 310, first body of rod section 311, second body of rod section 312 and thread segment 313.Wherein, the cross-sectional area of pressure head 310 is greater than the cross-sectional area of the first body of rod section 311, and the radius of the first body of rod section 311 is also greater than the radius of strut kong 4.
Can find out; when being subject to external pressure and making spring 32 that deformation occur, the radius due to the first body of rod section 311 is greater than the radius of strut kong 4, even if when the end face of the first body of rod section 311 contacts with the end face of strut kong 4; spring 32 is not just 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 arranging many group strut kongs 4, levelling depression bar 3 can be installed in these strut kongs 4 by operating personnel as required, with the back axle bag making pressing frock can mate different model.
Same, seaming chuck 22 and push-down head 12 also by selecting the form of different installation positions, can mate the back axle bag of different model.
Concrete, in the platen frock that above-described embodiment provides, in support component 1 and platen parts 2, comprise four groups of levelling depression bars 3 respectively.
Wrap in smoothing process to make back axle and keep static, further, in the pressing frock that above-described embodiment provides, be also provided with back axle bag backstay.
Back axle bag backstay is arranged on base plate 11, and the position relationship between many back axle bag backstays is determined according to the actual size of back axle bag.After being placed on support component 1 by pending back axle bag, many back axle bag backstays are clamped, and prevent pending back axle bag from rotating or offseting, thus make it in smoothing process, keep static.
Preferably, in order to the back axle bag making back axle bag backstay also can be applicable to different model, same employing arranges multiple backstay installing hole, back axle bag backstay is removably disposed in the mode in backstay installing hole.
In the process of smoothing back axle bag, cause back axle bag damaged to prevent support component 1 and platen parts 2 too close, base plate 11 is also provided with height limit bar 13.Understandable, height limit bar 13 concrete highly also relevant to the size of pending back axle bag, does not therefore specifically highly limit it.In the process of smoothing back axle bag, height limit bar 13 to make between base plate 11 and platen 21 minimally safe spacing, thus avoids both too close to causing back axle bag damaged.
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 additionally provides a kind of flattening equipment of back axle bag longitudinal seam.Concrete, comprise 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.
Flattening equipment provided by the present invention utilizes forcing press to drive pressing frock to process back axle bag, to smooth the longitudinal seam of back axle bag, thus alleviates the labour intensity of workman.Meanwhile, when the forcing press utilizing invention to provide is smoothed, noise is less, avoids noise and produces dysgenic problem to working site.
Concrete, the forcing press in above-mentioned platen equipment is hydraulic press or pneumatic press.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
