Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door panel rubber strip forming tooling, in particular to a door panel rubber strip forming tooling for vehicle doors. Background Technique
[0002] As a rubber seal, the rubber strip can be cut into different lengths according to needs and then glued together. Compared with the integral rubber seal, the glued rubber seal has a lower cost and can achieve a good sealing effect. Therefore, the rubber strip is widely used in the rail transit industry and is often used as a seal for door panels and windows. However, when cutting the rubber strip, if the cutting edge is not properly processed, the bonding effect of the butt joint will be poor, and there will be a gap, thus affecting its sealing effect.
[0003] When the door panel rubber strip forming tooling for vehicle doors is in use, the following defects still exist: At present, using a utility knife to cut the rubber strip easily causes the cutting plane to be uneven, and the cutting angles vary greatly each time. Especially when cutting a rubber strip with a larger diameter, it is more difficult to cut with a utility knife, the joint forming is poor, and it needs to be cut and corrected repeatedly, resulting in an unsatisfactory sealing effect.
