As a kind of preferred scheme, said power set comprise shift cylinder, and the piston rod of said shift cylinder is connected with die holder.
As a kind of preferred scheme, the bearing of trend of said slide rail is vertical with the moving direction of the draw mould of machine for shrinking.
As a kind of preferred scheme, said frame is provided with die holder is slided into the positioner that the clamping station positions.
As a kind of preferred scheme, said positioner comprises and the vertically arranged location-plate of slide rail that said clamping cylinder is installed on this location-plate.
As a kind of preferred scheme, said slide rail is two parallel slide rails, and said two one slide rails have constituted a wedge shape chute, and the bottom of wedge shape chute is equipped with smooth plate, and said die holder is slidingly mounted in the wedge shape chute and the die holder bottom contacts with smooth plate.
After having adopted technique scheme; The effect of the utility model is: because this clamping assembly comprises die holder, the upper clamp formwork that cooperatively interacts and lower clamp formwork; Frame is provided with slide rail, and die holder is slidingly mounted on the slide rail, and said lower clamp formwork is fixedly installed on the die holder; Said upper clamp formwork is installed on the lower clamp formwork through guide pillar and the vertical Elastic Sliding of back-moving spring, is equipped with on said upper clamp formwork and the following shut die to cooperate the clamping cavity that clamps tubing; Said die holder is connected with the power set that the driving die holder moves, and therefore, can drive die holder through power set and move; Make upper clamp formwork and lower clamp formwork leave the below of clamping cylinder; Upper clamp formwork and lower clamp formwork are to be in die opening state under the effect of back-moving spring like this, like this, no matter are when maintenance or more during mold exchange or during material loading; All can not have the accident of accidentally injuring and take place, thus the personal safety of assurance operation.
Because said slide rail is two parallel slide rails, and said two one slide rails have constituted a wedge shape chute, the bottom of wedge shape chute is equipped with smooth plate again; Said die holder is slidingly mounted in the wedge shape chute and the die holder bottom contacts with smooth plate; Therefore, die holder slides very smooth and easy, reduces friction.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation on the length direction of the utility model embodiment;
Fig. 2 is the structure cutaway view of Fig. 1 on the A-A direction;
In the accompanying drawing: 1. frame; 2. lower clamp formwork; 3. upper clamp formwork; 4. clamping cylinder; 5. steel pipe; 6. draw mould; 7. slide rail; 8. die holder; 9. location-plate; 10. shift cylinder.
The specific embodiment
Through specific embodiment the utility model is done further to describe in detail below.
Like Fig. 1, shown in Figure 2, a kind of machine for shrinking comprises frame 1; Be installed on the clamping assembly on the frame 1, be installed on the frame 1 and be positioned at the clamping cylinder 4 of clamping assembly top, wherein clamping cylinder 4 is to be fixedly installed on the installing plate.This clamping cylinder 4 drives the clamping assembly and clamps tubing, upper clamp formwork 3 and lower clamp formwork 2 that this clamping assembly comprises die holder 8, cooperatively interacts, and frame 1 is provided with slide rail 7, and the bearing of trend of said slide rail 7 is vertical with the moving direction of the draw mould 6 of machine for shrinking.Die holder 8 is slidingly mounted on the slide rail 7, and said frame 1 is provided with die holder 8 is slided into the positioner that the clamping station positions.Preferably; This positioner is the installing plate of clamping cylinder 4, and this installing plate is vertical with the direction that slide rail 7 extends, and installing plate was both used as the installation of clamping cylinder 4; Make location-plate 9 usefulness again positioning action is played in the motion of clamping assembly, guarantee that the clamping assembly is retracted to work station.Said lower clamp formwork 2 is fixedly installed on the die holder 8, and said upper clamp formwork 3 is installed on the lower clamp formwork 2 through guide pillar and the vertical Elastic Sliding of back-moving spring, is equipped with on said upper clamp formwork 3 and the following shut die to cooperate the clamping cavity that clamps tubing; Said die holder 8 is connected with the power set that driving die holder 8 moves.Said power set comprise shift cylinder 10, and the piston rod of said shift cylinder 10 is connected with die holder 8.
