Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic machinery, in particular to a device for assembling and processing rubber baffle plates. Background Art

[0002] Four rubber baffle plates are installed on the barrel through keys for use. As Figure 1 shown, the rubber baffle plate is a core part in an extrusion press, which is crucial for the overall quality of the extrusion press.

[0003] The existing key grooves of the four rubber baffle plates are all processed into finished products individually, and then installed and positioned on the barrel through keys. Due to the combined action of the precision errors of the key grooves of the rubber baffle plates and the barrel, after the rubber baffle plates are assembled and installed, the joint surfaces between the rubber baffle plates will have problems of excessive clearance. Therefore, it is necessary to quickly develop a new device for assembling and processing rubber baffle plates to solve the above problems.

[0004] Combined with Figure 2 , the position indicated by the arrow in the figure is the clearance position of the joint surface of the rubber baffle plate, which is caused by the precision error of the key groove processed individually during the processing of the rubber baffle plate. Secondly, the structure of the rubber baffle plate (lower rubber baffle plate) is thin, and the stress and thermal deformation errors generated during processing cause deformation. Due to the above two reasons, it is very difficult to ensure the technical requirements (<0.1 mm) for the joint surface clearance after the rubber baffle plates are assembled.

[0007] The device body 1 is mainly composed of a bottom plate and a vertical plate welded at 90°; on the vertical plate of the device body 1, there are respectively provided a rubber baffle plate fixing and fastening hole 7, a rubber baffle plate key groove processing hole 8, and a rubber baffle plate assembly positioning "∞" reference hole 9;

[0008] The rubber baffle plate is adjusted by rotating the adjusting screw rod 6; four rubber baffle plates are pre-assembled on the vertical plate of the device body 1. After confirming that the clearance between the joint surfaces of the rubber baffle plates is <0.1 mm, the rubber baffle plates are fixed on the vertical plate of the device body 1, and then the key grooves are processed integrally.

[0009] The rubber baffle keyway machining hole 8 is arranged around the rubber baffle assembly positioning "∞" reference hole 9.

[0010] The rubber baffle fixing bolt hole 7 is arranged around the rubber baffle keyway machining hole 8.

[0011] Four rubber baffle keyway machining holes 8 are provided.

[0012] Three or four bolt holes are arranged around each rubber baffle keyway machining hole 8.

[0013] The advantage of the present utility model lies in that a device is provided, and the rubber baffle can be integrally machined for the rubber baffle keyway after pre-assembly. By arranging the barrel keyway and the rubber baffle keyway on the same machine tool, the keyway machined by one-time positioning and clamping has high precision (≤±0.025mm), fully meeting the requirement of the clearance precision of the rubber baffle joint surface (<0.1mm), successfully solving the problem of material leakage caused by excessive clearance of the rubber baffle joint surface, and improving the overall operation quality of the extrusion tablet press.
