The model utility content
In order to solve in the existing press tool because interfered by the mould stiffening rib, the problem of side pin dismounting difficulty, the utility model provides a kind of operating position degree of depth that reduces bolt, elimination instrument and bolt tight bolt of side lock of being convenient to operate that cooperates a difficult problem in the confined space on mould.
The technical solution of the utility model is: a kind of tight bolt of being convenient to operate of side lock, and comprise bolt body and lengthen operating grip, lengthen operating grip and be welded on the bolt body.After the lengthening operating grip is set, need not in dim narrow space, to go for accurate bolt with instrument again, just can directly twist bolt body with hand-screw by lengthening operating grip from the place of bolt body away from, even sight line is bad, lengthening operating grip also gropes easily, so just can the tight bolt of time saving and energy saving ground dismounting side lock, make things convenient for the dismounting of die side pin greatly.
As preferably, lengthen operating grip and comprise handle bar and button, handle bar head axial along bolt body and bolt body welds, and button is fixedly arranged on handle bar free end.Button is made the shape of people's holds, and at handle pole length one regularly, button can be farthest away from bolt body, because handle bar trend is axially identical with bolt body, so the moment of torsion that produces during the turn button can be delivered on the bolt body with maximal efficiency.
As preferably, handle bar free end end face is provided with interior hexagonal nest hole.Sometimes bolt can be locked very tightly because never pulling down for a long time, and may also can't turn lengthen operating grip this moment only according to hand-power, and hexagonal nest hole lengthens on the operating grip, so that more high pulling torque to be provided for instruments such as torque spanner being connected in case of necessity exactly again in arranging.Because the handle bar has certain-length, can dwindle the degree of depth that stretches into of instrument, make instrument not by the mould stiffening rib interfere, circling round freely becomes possibility.
As an alternative, handle bar free end end face is provided with the hexagonal dop.After the hexagonal dop is set, also can help dismounting die side pin with this common tool of hexagonal socket wrench.
As preferably, button is a straight-bar, and this straight-bar is vertical with the handle bar.Button is vertical with the handle bar to be connected and to form T shape, with holds and to reverse augmented thrust ratio more convenient.
The beneficial effects of the utility model are:
Greatly facilitate the dismounting of die side pin.The utility model can directly be operated with hand, and the trouble when having reduced instrument and bolt and finding contraposition accurately has been avoided the interference of mould stiffening rib to instrument, makes that operation is time saving and energy saving.
Spend less and produce effects obviously.The utility model is made very simple, only needs to lengthen operating grip in the plain bolt welding and gets final product, and structure is very simple, and the process and remould expense is extremely low, uses but obviously to increase work efficiency, and reduces labor intensity.
