Abstract
The utility model discloses a device for fixing an extrusion stem. The device is characterized by at least comprising an extrusion stem (1), a gland (2), a guide fastening ring (3), a guide sleeve (4), a pressure bearing pad (5) and a movable beam (6). The pressure bearing pad (5) is fixedly connected with the movable beam (6), and a gap is reserved in the radial direction. The extrusion stem (1) is pressed on the pressure bearing pad (5) through the guide fastening ring (3). The guide sleeve (4) is arranged between the guide fastening ring (3) and the movable beam (6). The gland (2) is arranged outside the guide fastening ring (3). The device for fixing the extrusion stem solves the problem that the pressure bearing pad of the extrusion stem is not easy to change after deformation due to long-term use.
Description
Technical field
It is a kind of pressure ram fixture that the utility model relates to, and after solution dummy block pressure-bearing pad uses distortion for a long time, is difficult for splitting out the problem that is difficult to change.
Background technology
The extruder pressure ram is installed on the pressure-bearing pad of the moving beam of extruding; Extruding force is passed moving beam through the pressure-bearing dig pass, and is concentric with recipient and mould in order to guarantee pressure ram, and pressure ram radially must adopt little matched in clearance to be connected with the pressure-bearing pad; Pressure for a long time is squeezed; The pressure-bearing pad can be out of shape, and when needing to change, often can't split out.
Summary of the invention
The purpose of the utility model is a kind of pressure ram fixture of design, after solution dummy block pressure-bearing pad uses distortion for a long time, is difficult for splitting out the problem that is difficult to change.
The utility model solves the technical scheme that its technical problem adopted: a kind of pressure ram fixture; It is characterized in that: which comprises at least pressure ram, gland, guiding binding ring, fairlead, pressure-bearing pad, moving beam; The pressure-bearing pad is fixedly connected with moving beam, radially leaves the gap, and pressure ram is pressed on the pressure-bearing pad through the guiding binding ring; Between guiding binding ring and the moving beam fairlead is arranged, there is gland in the guiding binding ring outside.
Gap between described pressure-bearing pad and the moving beam is 2mm to 5mm.
The characteristics of the utility model are: this device pressure-bearing pad is radially mismatched with moving beam and is stopped enough gaps, even distortion still can split out very easily; The locking guider is not owing to consider the problem on deformation of pressure-bearing pad, and quality of fit can high one-level, and guide effect is better.
Description of drawings
Below in conjunction with implementing illustration the present invention is described further:
Fig. 1 is the utility model example structure figure.
Among the figure: 1, pressure ram; 2, gland; 3, guiding binding ring; 4, fairlead; 5, pressure-bearing pad; 6, moving beam.
The specific embodiment
Embodiment 1
A kind of pressure ram fixture; It is characterized in that: which comprises at least pressure ram 1, gland 2, guiding binding ring 3, fairlead 4, pressure-bearing pad 5, moving beam 6; Pressure-bearing pad 5 is fixedly connected with moving beam 6, radially leaves the gap, and pressure ram 1 is pressed on the pressure-bearing pad 5 through guiding binding ring 3; Between guiding binding ring 3 and the moving beam 6 fairlead 4 is arranged, there is gland 2 in guiding binding ring 3 outsides.
As shown in Figure 1, the utility model comprises pressure ram 1, gland 2, guiding binding ring 3, fairlead 4, pressure-bearing pad 5, moving beam 6 at least.Present embodiment is installed on pressure-bearing pad 5 on the moving beam 6 through bolt; Radially leave the 2mm gap; Pressure ram 1 is pressed on the pressure-bearing pad 5 through guiding binding ring 3, and pressure ram 1 adopts little matched in clearance with guiding binding ring 3, and cooperating through fairlead 4 between guiding binding ring 3 and the moving beam 6 realizes; Gland 2 is used for compressing guiding binding ring 3, thus locking pressure ram 1.
Basic identical with embodiment 2, institute's difference is that the gap between pressure-bearing pad 5 and the moving beam 6 is 5mm.
Extruding force acts on pressure-bearing pad 5 during pressure ram 1 work, and pressure-bearing pad 5 pressure-bearing is only radially mismatched with moving beam 6, leaves enough gaps, even distortion still can split out very easily; The locking guider is not owing to consider the problem on deformation of pressure-bearing pad 5, and quality of fit can high one-level, and guide effect is better.
Parts that present embodiment is not described in detail and structure belong to well-known components and the common structure or the conventional means of the industry, here not narration one by one.
Claims (2)
1. pressure ram fixture; It is characterized in that: which comprises at least pressure ram (1), gland (2), guiding binding ring (3), fairlead (4), pressure-bearing pad (5), moving beam (6); Pressure-bearing pad (5) is fixedly connected with moving beam (6), radially leaves the gap, and pressure ram (1) is pressed on the pressure-bearing pad (5) through guiding binding ring (3); Between guiding binding ring (3) and the moving beam (6) fairlead (4) is arranged, there is gland (2) in guiding binding ring (3) outside.
2. according to right 1 described a kind of pressure ram fixture, it is characterized in that: the gap between described pressure-bearing pad (5) and the moving beam (6) is 2mm to 5mm.
