Description

Technical Field

[0001] The utility model relates to the technical field of continuous extrusion forming, in particular to a cavity assembly, a boot seat assembly and a continuous extruder. Background Technique

[0002] A continuous extruder is the core equipment for realizing metal extrusion processing. As Figure 1 shown, it mainly includes structures such as a boot seat 1, a cavity 2, a feeding guide plate 3, a pressing plate 4, a stop block 5, an extrusion wheel 6 and a compaction wheel 7. Among them, the stop block 5 is embedded in the extrusion wheel groove, and there is a small gap between the two sides and the extrusion wheel 6. The cavity 2 is installed in the boot seat 1 and is pressed by the pressing plate 4 through the feeding guide plate 3. The extrusion wheel 6 is driven by a motor. The raw material copper rod 8 enters the extrusion wheel groove, is pressed by the compaction wheel 7, and is tractioned by the frictional force of the extrusion wheel groove wall along the closed arc-shaped cavity into the cavity 2, and the product 9 is extruded under the action of high temperature and high pressure.

[0003] Among them, as Figure 2 and Figure 3 shown, the feeding guide plate 3 is a strip-shaped structure as a whole. The center of the boot seat 1 is provided with a groove matching the width dimension of the feeding guide plate 3, which plays a positioning role and can ensure that the feeding guide plate 3 is located at the center of the boot seat 1, that is, the center line of the feeding guide plate 3 is collinear with the center line 101 of the boot seat. The lower end of the feeding guide plate 3 is a plane, and the upper end of the cavity 2 is also correspondingly provided with a groove at the contact position with the feeding guide plate 3. During the production of the continuous extruder, especially for large extruders, it is necessary to heat the cavity 2 for a long time in advance, and the heating temperature is above 500 °C. Due to thermal expansion, the width of the groove on the cavity 2 that cooperates with the feeding guide plate 3 becomes larger, and then it is impossible to ensure that the cavity 2 is located at the center of the boot seat 1 after assembly, resulting in friction between the stop block 5 and the extrusion wheel 6 and causing losses.

[0004] Therefore, there is an urgent need to provide a cooperation scheme for the feeding guide plate and the cavity to solve the above problems existing in the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cavity assembly, a boot seat assembly and a continuous extruder to solve the problems existing in the above prior art, and can ensure the accurate positioning of the cavity, prevent the stop block from rubbing against the extrusion wheel due to the position deviation of the cavity, and cause losses.

The opening of the limiting groove faces the material guiding plate, so that the limiting portion can enter the limiting groove to achieve limiting. Wherein, there is an included angle between the side walls on both sides in the width direction of the limiting portion.

[0008] Preferably, the limiting portion is a V-shaped limiting portion, and the limiting groove is a V-shaped limiting groove.

[0009] Preferably, the included angle between the side walls on both sides in the width direction of the limiting portion is 60° - 120°.
