Postponing mold for cutting of hollow rubber hose

Abstract

The invention relates to a postponing mold for cutting of a hollow rubber hose. An upper mold with a diagonal plane I and a lower mold with a diagonal plane II are connected. The P-shaped rubber hose is effectively supported through clamping and fixation of the P-shaped pipe with the upper mold, the lower mold and a positioning pin. It is guaranteed that the hose is not deformed during cutting of a cutter, work efficiency is improved, and the phenomenon of excess of difference is avoided.

Description

technical field [0001] The invention relates to a mold and its application, in particular to a hollow rubber hose cutting and positioning mold and its application, belonging to the field of processing. Background technique [0002] During the installation process of the Q400 fuselage system, a hollow P-shaped rubber hose needs to be bonded to the groove-shaped protective bracket to protect the product structure. The P-shaped rubber hose needs to be cut at 45 degrees and placed on the Apply adhesive on the cross-section to bond the two hoses. During the operation, it is necessary to ensure that the cutting angles of the two rubber hoses to be bonded are consistent, so that the same cross-sectional area can be obtained. At the same time, the cutting angle must be ensured. There is no deformation, protrusion or depression on the surface, ensuring that the cross-section can be fully contacted. In actual operation, use an angle ruler for positioning. The angle error is large, and...

[0002] During the installation process of the Q400 fuselage system, a hollow P-shaped rubber hose needs to be bonded to the groove-shaped protective bracket to protect the product structure. The P-shaped rubber hose needs to be cut at 45 degrees and placed on the Apply adhesive on the cross-section to bond the two hoses. During the operation, it is necessary to ensure that the cutting angles of the two rubber hoses to be bonded are consistent, so that the same cross-sectional area can be obtained. At the same time, the cutting angle must be ensured. There is no deformation, protrusion or depression on the surface, ensuring that the cross-section can be fully contacted. In actual operation, use an angle ruler for positioning. The angle error is large, and it is difficult to obtain a completely consistent cross-sectional area. After bonding, the two pieces of rubber are soft. There is a step difference in the axial direction of the tube, which cannot meet the customer's requirements. During the cutting process, because the P-shaped rubber hose used is a hollow material and is very soft, the pressure on the tool will cause the hose to break down during the cutting process. Deformation affects the surface quality of the cut cross-section, and produces certain sharp-edged protrusions and depressions on the cut surface. Such hose surfaces cannot be fully contacted during the bonding process, which reduces the bonding strength and is easy to be used in subsequent assembly or use. Shedding occurs in
