Description
Technical Field
The utility model belongs to the technical field of auto parts makes, specifically speaking, the utility model relates to a take hollow structure's extra income to cut sealing strip.
Background
The outer water cutting sealing strip is one of important sealing parts of an automobile, is arranged on the outer sides of an automobile door and an automobile window, and has the functions of dust prevention, water prevention, noise prevention, appearance decoration and the like; as an appearance decorative part, the requirement on the appearance is high.
The design that the sealing strip was cut to extra income is received the figurative influence of door panel beating great, and the figurative difference of door panel beating leads to the different structure of installing the extra income and cutting the sealing strip, leads to the different outward appearance molding structure of extra income cutting the sealing strip.
There are two broad categories that can be broadly classified: one type is a straight external water cut sealing strip, as shown in fig. 1; another type is a curved profile of the outer water cut seal strip as shown in fig. 2. The bending-shaped external water cutting sealing strip can be divided into: 1) bending in the Y direction; 2) bending in the Z direction; 3) three-dimensional bending (i.e., the X \ Z directions exist in a bending state at the same time).
The flat-shaped external horizontal cutting sealing strip is generally formed by extrusion molding by taking a flat steel strip or a double-rib steel strip as a core material. The flat steel belt can effectively prevent the product from shrinking and has the appearance decoration effect.
The outer water cutting sealing strip with the bending shape is generally formed by extruding a flat steel strip and then subjected to secondary stretch bending processing to form a bending radian to be assembled with a vehicle door metal plate in a matching way.
In order to support and clamp the external water-cut sealing strip, a steel strip is used as a core material in a common product to be co-extruded, and then secondary processing is performed as shown in fig. 3. The steel strip has two forms, a flat steel strip and a double-rib steel strip. The secondary processing procedure can also be different by selecting different types of steel strips:
1) the flat steel strip shown in fig. 4 is selected as a core material to be co-extruded, and a stretch bending forming process is added in the secondary processing production process, so that the cost of the product is greatly increased, for example: mould, examine utensil, cost of labor.
In addition, the product formed by stretch bending needs to be assembled by matching with a bent vehicle door metal plate, the assembly can be completed only when the bending radian is consistent with the bent vehicle door metal plate, so that the precision requirement on the product is high, and the yield of the product can be reduced when the stretch bending forming process is performed on the product.
2) The double-rib steel belt shown in the figure 5 is selected as a core material to be co-extruded, and due to the fact that certain bending performance exists after the double-rib steel belt is formed, a stretch bending forming process of secondary processing can be omitted, the double-rib steel belt is directly installed on a car door metal plate, but due to the fact that the double-rib steel belt is adopted, shrinkage marks can be generated on the surface of an outer water cutting sealing strip, the appearance quality of a product is affected, the overall quality is reduced, and attractiveness is affected.
SUMMERY OF THE UTILITY MODEL
The utility model provides an external water cutting sealing strip with a hollow structure, which avoids the secondary stretch bending forming process of the external water cutting sealing strip by adopting a flat steel strip to perform coextrusion, reduces the production cost and ensures the product percent of pass; the external water cutting sealing strip which is formed by co-extruding the double-rib steel strip has certain three-dimensional bending property, avoids a secondary stretch bending forming process and reduces the production cost; solves the problem of surface sink marks of the product obtained by co-extruding the double-rib steel belt.
In order to realize the purpose, the utility model discloses the technical scheme who takes does: the outer water cut sealing strip with the hollow structure comprises a vehicle door outer plate, a vehicle door inner plate and vehicle door glass, wherein the upper end of the vehicle door outer plate wraps the vehicle door inner plate, the outer water cut sealing strip is further arranged, the vehicle door glass is in contact with the outer water cut sealing strip, the outer water cut sealing strip is composed of a metal framework and a wrapping soft rubber, and the metal framework is wrapped by the wrapping soft rubber and then extruded and molded; the metal framework adopts a double-rib steel belt; a cavity is arranged in the coated soft rubber.
Preferably, a plurality of sawtooth projection structures are arranged on the surface, close to the metal framework, in the cavity at equal intervals.
Preferably, the sawtooth protrusion structure is intersected with the rib groove on the double-rib steel belt.
Preferably, the sawtooth protrusion structure is perpendicular to the rib groove on the double-rib steel belt.
The beneficial effect of adopting above technical scheme is:
1. this take sealing strip is cut to hollow structure's extra income, metal framework adopt two muscle steel bands, because have certain three-dimensional bending property after two muscle steel bands carry out the coextrusion shaping, can satisfy the crooked radian of installation of door panel beating, so need not carry out the secondary stretch bending shaping to the product, can practice thrift the manufacturing cost of product greatly, avoided the problem that the qualification rate that the stretch bending process caused is low simultaneously, improved the qualification rate of product.
2. The coating soft rubber is internally provided with a cavity, so that the generated shrinkage mark is hidden on the surface close to the metal framework in the cavity, and the appearance surface of the outer water cut sealing strip is separated from the double-rib steel belt by the cavity, so that the shrinkage mark cannot be generated on the appearance surface of the outer water cut sealing strip, and the quality of the appearance surface is ensured.
A plurality of sawtooth projection structures are arranged on the surface, close to the metal framework, in the cavity at equal intervals, the action effect of contraction force is reduced through the sawtooth projection structures, and the depth of contraction marks is reduced; the sawtooth protruding structure is intersected with the rib groove on the double-rib steel belt, and further the sawtooth protruding structure is perpendicular to the rib groove on the double-rib steel belt, so that the depth of a shrinkage mark is reduced to the greatest extent.
