Detailed description of the invention
Advantage of the present utility model is set forth further below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, the utility model discloses a kind of dummy block device, comprise pressure ram 1, extruding cushion cover 2 and extruding cushion block 3.The right-hand member of extruding cushion cover 2 is connected with the left end of pressure ram 1; Extruding cushion block 3 is roughly truncated cone-shaped, and the left end of extruding cushion cover 2 is provided with and the depression extruding cushion block 3 form fit, and extruding cushion block 3 is removably plugged in the depression of the left end of extruding cushion cover 2; The left end of pressure ram 1 is provided with accommodation section 11, and extruding cushion cover 2 runs through vertically and is fixed with connecting rod 4, and the right-hand member of connecting rod 4 stretches in accommodation section 11, is connected, thus is connected with pressure ram 1 by extruding cushion cover 2 by connecting rod 4 with pressure ram 1.In the recessed accommodation section 11 of the left end of pressure ram 1, an external connecting rod 4 on extruding cushion cover 2, by the connection of connecting rod 4 with pressure ram 1, extruding cushion cover 2 and pressure ram 1 are linked together, further, accommodation section 11, connecting rod 4, pressure ram 1, extruding cushion cover 2 and extruding cushion block 3 are coaxially arranged.
As shown in Figure 2, meeting in dummy block device of the present utility model, extruding cushion cover 2 opposing compression bar 1 can move to second place B from primary importance A, when extruding cushion cover 2 and being positioned at primary importance A, extruding cushion cover 2 can freely grafting or depart from pressure ram 1, when extruding cushion cover 2 and being positioned at second place B, extruding cushion cover 2 interfixes with pressure ram 1.
As shown in Figure 2, meeting in dummy block device of the present utility model, the left end opening of accommodation section 11 is arranged to internal spline (not shown), and accordingly, the right-hand member of extruding cushion cover 2 is set to external splines 21.Preferably, when extruding cushion cover 2 and being positioned at primary importance A, internal spline and external splines 21 coincide.Internal spline and external splines 21 are quincunx.
As shown in Figure 3, in dummy block device, also comprise alignment pin 5, when extruding cushion cover 2 and being positioned at second place B, alignment pin 5 locks pressure ram 1 and connecting rod 4 along the radial direction of pressure ram 1.This is one and rotates fixing snap-in structure, when primary importance A, the external splines 21 of extruding cushion cover 2 aims at the breach of the internal spline of accommodation section 11, then the accommodation section 11 of pressure ram 1 is injected by this breach, until the extruding right-hand member of cushion cover 2 and the left end of pressure ram 1 are fitted, then rotary squeezing cushion cover 2, makes extruding cushion cover 2 move to second place B from primary importance A, then by alignment pin 5, pressure ram 1, connecting rod 4 are connected in series fixing, thus realize the fixing of dummy block device.
As shown in Figure 3, the right-hand member of extruding cushion block 3 is threaded with the left end of connecting rod 4, the surface of the right-hand member of extruding cushion block 3 is provided with positioning step 31, more specifically, positioning step 31 is arranged on the edge of extruding cushion block 3 right end face, by positioning step 31, extruding cushion block 3 does not rotate relative to extruding cushion cover 2.
Preferably, the internal diameter of external diameter slightly larger than extruding cushion cover 2 of cushion block 3 is extruded.When extruding cushion block 3 pressurized, extruding cushion cover 2 produces and small extends out deformation, and extruding cushion cover 2 is coordinated with recipient (not shown) better.
Preferably, the left end center of extruding cushion block 3, namely there is circular protrusions 32 at compression face center.
The dummy block device fixed is installed and namely can be used for profile extrusion, when extruding, the extruding cushion block 3 of dummy block device directly contacts with ingot blank, the external diameter of extruding cushion block 3, slightly larger than the internal diameter of extruding cushion cover 2, after extruding cushion cover 2 is under pressure, produces miniature deformation, preferably, the deflection of extruding cushion cover 2 is 0.75mm, and extruding cushion cover 2 is extended to complete sealing extrusion cylinder, guarantees that aluminium can not flow out from recipient rear end.When extruding completes, when pressure ram 1 retreats, pressure reduces, and extruding cushion cover 2 recovers original dimension, exits recipient.
Have employed after meeting dummy block device of the present utility model, can use for a long time after dummy block device of the present utility model installation, operating personnel, without the need to each extrusion cycle carrying and installation pad, save manpower and time; Extruding cushion block 3 can not drop and be clashed into, and weares and teares little, long service life; The external diameter of extruding cushion block 3 is slightly larger than the internal diameter extruding cushion cover 2, and when cushion block pressurized, cushion cover generation is small extends out deformation, makes it better to coordinate with internal diameter of the container, prevents recipient end and run aluminium.
