Abstract
The invention discloses an elbow anti-skid device and relates to the technical field of die manufacture. The device comprises a bent die with one side provided with an arc, the upper end of the bent die is provided with a concave arc groove and extends along the arc to the lower end, a clamping die is arranged on the bent die, and the lower end of the clamping die is provided with a concave arc groove corresponding to the concave arc groove at the upper end of the bent die to form a cylindrical hole; a guide die is arranged on one side of the clamping die and is located on the arc of the bent die, the lower end of the guide die is provided with a concave arc groove, and the axis of the concave arc groove of the guide die and that of the concave arc groove of the clamping die are on the same axis; a plurality of grooves are formed in the cylindrical hole radially. Compared with the prior art, the device has the advantages that the friction coefficient of the device and a pipe is increased, skid between the bent die and the clamping die and the pipe during pipe bending is avoided, the bending position of the pipe is accurate, and the qualified rate of the elbow is high.
Description
Technical field
The present invention relates to technology of die manufacturing field, especially a kind of bend pipe shoe.
Background technology
The pipeline of many machinery equipments connects all will use bend pipe, conventionally adopt bend pipe mould to carry out bend pipe, now commonly use a kind of swan neck system, this swan neck system comprises that a side is provided with the curved mould of circular arc, the upper end of described curved mould is provided with concave arc groove and extends to lower end along described circular arc, above described curved mould, be provided with clamping, the lower end of described clamping is provided with concave arc groove, and the concave arc groove of the concave arc groove of described clamping and described curved mould upper end is relative and form a cylindrical hole; In a side of described clamping and above being positioned at the circular arc of described curved mould, be provided with guided mode, the lower end of described guided mode is provided with concave arc groove, and the axis of the axis of described guided mode concave arc groove and described clamping concave arc groove is on same axis.Because the groove part of curved mould and clamping is level and smooth, curved mould and clamping and need between crooked pipe coefficient of friction less, easily produce and slide and be shifted between curved mould and clamping and pipe during bend pipe, causes the position skew of tube bending, and bend pipe qualification rate is low.
Summary of the invention
The position that technical problem to be solved by this invention is to provide a kind of tube bending is bend pipe shoe accurately, solves and between bend pipe mould and pipe, produces the problem of sliding.
In order to address the above problem, the technical solution used in the present invention is: this bend pipe shoe, comprise that a side is provided with the curved mould of circular arc, the upper end of described curved mould is provided with concave arc groove and extends to lower end along described circular arc, above described curved mould, be provided with clamping, the lower end of described clamping is provided with concave arc groove, and the concave arc groove of the concave arc groove of described clamping and described curved mould upper end is relative and form a cylindrical hole; In a side of described clamping and above being positioned at the circular arc of described curved mould, be provided with guided mode, the lower end of described guided mode is provided with concave arc groove, and the axis of the axis of described guided mode concave arc groove and described clamping concave arc groove is on same axis; In described cylindrical hole, be radially provided with a plurality of grooves.
In above-mentioned bend pipe shoe technical scheme, technical scheme can also be more specifically: the lower end of described curved mould is provided with the concave arc groove being connected with the concave arc groove of described circular arc.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention is radially provided with a plurality of grooves in the concave arc groove of the clamping cylindrical hole also forming relative to the concave arc groove of curved mould upper end, increased the coefficient of friction between curved mould and clamping and pipe, while avoiding bend pipe, between curved mould and clamping and pipe, produce and slide, the position of tube bending is accurate, and bend pipe qualification rate is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
A kind of bend pipe shoe as shown in Figure 1 and Figure 2, comprises that a side has the curved mould 1 of circular arc, and the upper end of curved mould 1 has concave arc groove and extends to lower end along circular arc, and the lower end of curved mould 1 has the concave arc groove being connected with the concave arc groove of circular arc; Clamping 2 is housed above curved mould 1, and the lower end of clamping 2 has concave arc groove, and the concave arc groove of the concave arc groove of clamping 2 and curved mould 1 upper end is relative and form a cylindrical hole, radially has seven spaced grooves in cylindrical hole; In a side of clamping 2 and above being positioned at the circular arc of curved mould 1, guided mode 3 is housed, the lower end of guided mode 3 has concave arc groove, and the axis of the axis of guided mode 3 concave arc grooves and clamping 2 concave arc grooves is on same axis.
During work, bend pipe shoe is arranged on bending machine, pipe is put into the concave arc groove of curved mould 1 upper end, guided mode 3 is close to pipe, clamping 2 is with curved mould 1 by tube grip, and contrary with the guided mode 3 in the same way direction of clamping 2 and curved mould 1 one is along the central rotation of curved mould 1 circular arc, and pipe is brake forming thereupon.In the concave arc groove of clamping 2 cylindrical hole that also form relative to the concave arc groove of curved mould 1 upper end, be radially provided with seven grooves, increased the coefficient of friction between curved mould and clamping and pipe, while avoiding bend pipe, between curved mould 1 and clamping 2 and pipe, produce and slide, the position of tube bending is accurate, and bend pipe qualification rate is high.
Claims (2)
1. a bend pipe shoe, comprise that a side is provided with the curved mould (1) of circular arc, the upper end of described curved mould (1) is provided with concave arc groove and extends to lower end along described circular arc, in the top of described curved mould (1), be provided with clamping (2), the lower end of described clamping (2) is provided with concave arc groove, and the concave arc groove of the concave arc groove of described clamping (2) and described curved mould (1) upper end is relative and form a cylindrical hole; In a side of described clamping (2) and the circular arc top that is positioned at described curved mould (1), be provided with guided mode (3), the lower end of described guided mode (3) is provided with concave arc groove, and the axis of the axis of described guided mode (3) concave arc groove and described clamping (2) concave arc groove is on same axis; It is characterized in that: in described cylindrical hole, be radially provided with a plurality of grooves.
