Abstract
The utility model belongs to a device for an aluminum and aluminum alloy extrusion machine, in particular to an extrusion stem quick-change device of a large-sized extrusion machine, which is characterized by comprising an extrusion stem press plate (4), a hold-down bolt (3) and an extrusion stem (2), an extrusion stem base plate (5) is connected to an aluminum alloy extrusion machine moving transverse beam (6) through bolts, the extrusion stem press plate (4) is connected with the extrusion stem base plate (5) through the hold-down bolt (3), the extrusion stem (2) is clamped in a clearance between the extrusion stem press plate (4) and the extrusion stem base plate (5), and an extruding cushion (1) is in threaded connection with the extrusion stem (2). The utility model brings convenience for resolving the problem that the extrusion stem quick-change device is not easy to rotate or be changed quickly.
Description
Technical field
The utility model belongs to the device, particularly large-size extruder pressure ram quick replacement device that aluminium and aluminum alloy extruder are used.
Background technology
At existing pressure ram more in the changing device, the mode that adopts motor reducer or oil cylinder rotation pressure ram pressing plate is arranged, this kind structure is in long-term use, because the subsides of faying face extremely often cause motor reducer or oil cylinder to rotate motionless pressure ram pressing plate, what have does not adopt quick replacement device, and causing pressure ram to change wastes time and energy.
Summary of the invention
The purpose of this utility model provides a kind of extruder pressure ram quick replacement device, so that solve the pressure ram more difficult rotation of changing device and quick-replaceable problem.
The purpose of this utility model is to realize like this, the pressure ram quick replacement device, it is characterized in that: comprise pressure ram pressing plate, hold-down bolt and pressure ram, on the aluminum alloy extruder moving beam, connect the pressure ram backing plate by bolt, the pressure ram pressing plate is connected by hold-down bolt with the pressure ram backing plate, and pressure ram is connected in the gap between pressure ram pressing plate and the pressure ram backing plate; Dummy block and pressure ram are threaded.
The cross sectional shape that described pressure ram pressing plate and pressure ram bottom adopt rectangle and circular arc to join.
The utility model has the advantages that: adopt hold-down bolt to compress the pressing plate of pressure ram, the cross sectional shape that pressure ram pressing plate and pressure ram bottom adopt rectangle and circular arc to join, when changing pressure ram, do not need to take out hold-down bolt, only need unclamp hold-down bolt, rotate angle of pressure ram then, can take off pressure ram fast.
Description of drawings
The utility model is described in further detail below in conjunction with example figure.
Fig. 1 is the utility model embodiment structural representation;
Fig. 2 is the right view of Fig. 1.
Among the figure: 1, fixation extrusion pad; 2, pressure ram; 3, hold-down bolt; 4, pressure ram pressing plate; 5, pressure ram backing plate; 6, aluminum alloy extruder moving beam.
The specific embodiment:
As depicted in figs. 1 and 2, comprise pressure ram pressing plate 4, hold-down bolt 3 and pressure ram 2, on aluminum alloy extruder moving beam 6, connect pressure ram backing plate 5 by bolt, pressure ram pressing plate 4 is connected by hold-down bolt 3 with pressure ram backing plate 5, and pressure ram 2 is connected in the gap between pressure ram pressing plate 4 and the pressure ram backing plate 5; Dummy block 1 and pressure ram 2 are threaded.The cross sectional shape that pressure ram pressing plate 4 and pressure ram 2 bottoms adopt rectangle and circular arc to join.When changing pressure ram 2, unclamp hold-down bolt 3, produce the gap between pressure ram pressing plate 4 and the pressure ram backing plate 5, pressure ram 2 is turned an angle, when the rectangle of the rectangle of pressure ram 2 and pressure ram pressing plate 4 overlaps, pressure ram 2 can be taken out.
Claims (2)
1, pressure ram quick replacement device, it is characterized in that: comprise pressure ram pressing plate (4), hold-down bolt (3) and pressure ram (2), go up by bolt connection pressure ram backing plate (5) at aluminum alloy extruder moving beam (6), pressure ram pressing plate (4) is connected by hold-down bolt (3) with pressure ram backing plate (5), and pressure ram (2) is connected in the gap between pressure ram pressing plate (4) and the pressure ram backing plate (5); Dummy block (1) and pressure ram (2) are threaded.
2, pressure ram quick replacement device according to claim 1 is characterized in that: the cross sectional shape that described pressure ram pressing plate (4) and pressure ram (2) bottom adopt rectangle and circular arc to join.
