The utility model discloses a die lifting device used for a pipe-bending machine. The die lifting device used for the pipe-bending machine comprises a machine body, a die seat which can slide up and down is arranged on the machine body, a wedge block which can slide horizontally is arranged at the bottom of the machine body, steps are arranged on the surface of the wedge block, the die seat is provided with rolling wheels, and the rolling wheels are arranged on the steps of the wedge block. The wedge block horizontally slides to push the rolling wheels to be arranged on the steps of different layers, the rolling wheels which are arranged on the steps of the different layers push the die seat to slide up and down, and a fixed manner that tail portions of two sets of oil cylinders are connected is adopted by the wedge block, horizontal movement of the wedge block is utilized to push the die seat to move up and down, compared with a lead screw manner, the fixed manner is stable and not easy to abrade, the fixed manner that the tail portions of two sets of the oil cylinders are connected is adopted by the wedge block, and the wedge block is guaranteed to be stable, solid and in place.

Description

The die lifting device that is used for bending machine

Technical field

The utility model relates to a kind of die lifting device for bending machine.

Background technology

Existing die lifting device for bending machine, its mold base mainly rely on motor and leading screw effect along the fuselage oscilaltion, and mold base is mainly used in filling the critical pieces such as mould, head, bending pipe arm.Yet, this use leading screw carries out the form of lifting, on the one hand, leading screw uses easy damaged for a long time, on the other hand, and when elbow radius is smaller, need to use core-pulling device, this moment, core-pulling device can play to leading screw the power of vertical direction, and the servomotor that link to each other with leading screw this moment will be subject to the power above its rated load, caused servomotor to be reported to the police.Servomotor is shut down, and causes the follow-up several procedures of bend pipe to move.And elbow member is stuck in bend pipe mould, thereby causes pipe fitting to be scrapped.In addition, servomotor works long hours its power can be not enough, causes the leading screw mobile accuracy not enough.

The utility model content

Technical problem to be solved in the utility model is: a kind of die lifting device for bending machine is provided, and its mold base oscilaltion is stable.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the die lifting device that is used for bending machine, comprise fuselage, the up and down mold base of slippage is installed on the described fuselage, but described fuselage bottom is equipped with the voussoir of horizontal sliding, the voussoir upper surface has the sloping step of one deck one side band at least, and the lower end of mold base is provided with roller, and roller contacts with the upper surface of voussoir.

Described voussoir has 2 layers of step.

Described voussoir horizontal sliding pushing rolling wheels is positioned at the step of different layers, and the step that described roller is positioned at different layers impels up and down slippage of mold base.

The fixed form that described voussoir adopts 2 cover oil cylinder afterbodys to link to each other.

Described mold base is installed on the fuselage by the slide rail on both sides.

The ramp angles of described step is 30 °～45 °

The beneficial effects of the utility model are: the utility model utilizes moving horizontally of voussoir to promote mold base and moves up and down, and the promotion of this form is comparatively stablized than the leading screw form and is difficult for impaired.Voussoir horizontal sliding pushing rolling wheels is positioned at step and then so that the up and down slippage of mold base of different layers.The fixed form that voussoir adopts 2 cover oil cylinder afterbodys to link to each other like this, guarantees that voussoir stops at single cylinder extreme position to put in place, can sideslip or excessive, and guarantee that voussoir is firm, put in place.

The specific embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.

Shown in Figure 3 such as Fig. 1 Fig. 2, a kind of die lifting device for bending machine, comprise fuselage 1, the up and down mold base 2 of slippage is installed on the fuselage 1, but fuselage 1 bottom is equipped with the voussoir 3 of horizontal sliding, and voussoir 3 upper surfaces are provided with at least sloping step of one deck one side band, and the concrete quantity of step is decided according to the actual requirements, adopt two steps in the present embodiment, namely voussoir 3 has 3 layers of platform that can supply roller 3 to roll.Mold base 2 lower ends are provided with roller 4, and roller 4 contacts and can be rolled on the step from the upper surface of voussoir 3 with the upper surface of voussoir 3.Mold base 2 is installed on the fuselage 1 by the slide rail on both sides.Reduce the resistance that voussoir 3 is received roller 3 in the situation for the mobile space of reasonable arrangement voussoir 3, the ramp angles of described step is 30 °～45 ° as far as possible.

Voussoir 3 horizontal sliding pushing rolling wheels 4 are positioned at the step of different layers, and the step that roller 4 is positioned at different layers impels mold base slippage about in the of 2.As shown in Figure 1, roller 4 is positioned at the upper surface of voussoir 3, when voussoir 3 slippage left, roller 4 is moved upward on the ground floor step 6 along the slope of ground floor step 6, because voussoir 3 moves horizontally, therefore mold base 2 is subjected to the slippage that makes progress of voussoir 3 thrusts, just can realize the mould on the mold base 2 is once switched this moment---Fig. 2, if also will another mould on the mold base 2 be switched, voussoir 3 can be moved to the left again, so that roller 4 goes another step---second step 7, thereby so that mold base 2 moves up again the switching mould---such as Fig. 3.In like manner, voussoir 3 slippage to the right can realize mold base 2 downward slippages, thereby realizes that mold base 2 is with respect to the elevating movement of fuselage 1.

The fixed form that voussoir 3 adopts 2 cover oil cylinders, 5 afterbodys to link to each other.Like this, guarantee that voussoir 3 stops at single cylinder 5 extreme positions to put in place, can sideslip or excessive, guarantee that voussoir is 3 firm, put in place.

The utility model utilizes moving horizontally of voussoir 3 to promote mold base 2 and moves up and down, and the promotion of this form is comparatively stablized than the leading screw form and is difficult for impaired.
