Description
Technical field
The utility model relates to a kind of straightener, and more particularly, it relates to a kind of novel aperture structure of straightener.
Background technology
Straightener is mainly used in the sheet material corrected all size sheet material and cut into block, and because it is convenient and simple for operation, range of application spreads all over multiple industries such as machinery, metallurgy, building materials, chemical industry, electronics, electric power, light industry.
Straightener needs to adjust top working roll before aligning workpiece, makes top working roll assembly around center rotating certain angle, namely adjusts straightener opening degree (with reference to accompanying drawing 4).Top working roll assembly can effectively ensure to align the steadily stressed of workpiece after opening has adjusted, when needs adjustment different openings is spent, the aperture structure of traditional straightener as shown in Figure 3, slide mutually at sliding surface in the pommel of top working roll assembly and screw mandrel, all the time be the contact of a some face in this process, in the process of working long hours, easily wear and tear in the pommel of screw mandrel.Cause the problems such as the stressed difference of screw mandrel in straightening operation, adjustment opening is steady, screw mandrel easily damages.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of screw mandrel uniform force, and aperture is steady, the novel aperture structure of the straightener that adaptability is wider.
For achieving the above object, the utility model provides following technical scheme to realize:
A kind of novel aperture structure of straightener, the Worm-gear assembly comprising top working roll, bottom working roll, gland and be arranged on gland, working roller assembly is fixed with between described gland and top working roll, the limited cover that described working roller assembly includes spaced roll stand and is placed in roll stand, cushion pad is fixed with between described roll stand and limited cover, this cushion pad relative limit lid side is provided with deep-slotted chip breaker, described Worm-gear assembly is connected with screw mandrel, one end of this screw mandrel be provided with run through limited cover and with deep-slotted chip breaker abut against spherical support block.
As preferably: be connected with stop nut in described gland, this stop nut to be placed in directly over limited cover and to be spirally connected with described screw mandrel.
As preferably: between described top working roll and bottom working roll, space crossings is arranged.
As shown from the above technical solution, the beneficial effect of this practicality is:
Compared to existing technology, by cushion pad and offer on cushion pad with spherical support that block abuts deep-slotted chip breaker the structure replacing conventional point face and contact is set, have the following advantages, 1 realizes the contact between face and face, make screw mandrel in the process of working long hours, be not easy wearing and tearing, effectively ensure that screw mandrel uniform force; 2, cushion pad has certain buffering effect and effectively ensures steady in aperture process of straightener; 3, cushion pad also has certain contractive effect soon, and the extreme angles that can adjust opening degree is also larger, improves straightener further to the adaptability of different plates thickness.
In the utility model: arranging of stop nut is effectively avoided spinning, guarantee that screw mandrel can axially move in frame, and between top working roll and bottom working roll, space crossings also effectively avoids sheet material to skid in straightening process while being arranged on guarantee straightener aligning degree.

Fig. 1 is the schematic diagram of the novel aperture structure of a kind of straightener of the utility model;
Fig. 2 is the structural representation of the utility model aperture state;
Fig. 3 is the schematic diagram of the aperture structure of traditional straightener.
Fig. 4 is the structural representation of traditional straightener aperture state.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, the embodiment of the novel aperture structure of a kind of straightener of the utility model is described further.
A kind of novel aperture structure of straightener, comprise top working roll 1, bottom working roll 2, gland 3 and the Worm-gear assembly 4 be arranged on gland 3, working roller assembly 5 is fixed with between described gland 3 and top working roll 1, the limited cover 52 that described working roller assembly 5 includes spaced roll stand 51 and is placed in roll stand 51, cushion pad 53 is fixed with between described roll stand 51 and limited cover 52, this cushion pad 53 relative limit lid 52 side is provided with deep-slotted chip breaker 531, described Worm-gear assembly 4 is connected with screw mandrel 6, one end of this screw mandrel 6 be provided with run through limited cover 52 and with deep-slotted chip breaker 531 abut against spherical support block 61, stop nut 7 is connected with in described gland 3, this stop nut 7 to be placed in directly over limited cover 52 and to be spirally connected with described screw mandrel 6, between described top working roll 1 and bottom working roll 2, space crossings is arranged.
On adjusting during the aperture of straightener: rotary worm, worm gear is driven to rotate.By spline joint, screw mandrel 6 is driven to rotate.By being threaded between screw mandrel 6 with stop nut 7, thus screw mandrel 6 is axially moved on gland.Two rhizoid bars 6 move axially relative diverse location, deep-slotted chip breaker 531 on cushion pad 53 relatively rotates around the spherical center supporting block 61 at the slip surfaces of revolution with the spherical block 61 that supports on screw mandrel 6, top working roll assembly 5 presses down while tilt, to obtain different openings degree, the contact of the face that ensures all the time in this process effectively ensure that aligning silk aperture steadily and the uniform force of screw mandrel 6.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
