Embodiment Construction

[0011] The specific embodiment of the present invention will be described below in conjunction with the drawings.

[0012] Such as figure 1 As shown, the processing device includes a mandrel 1, a rubber hoop lower hoop 8, a rubber hoop upper hoop 2, a spherical stopper 4, a positioning plate 3, a stabilizing body 5, and a screw 9.

[0013] Such as figure 2 As shown, install the positioning disc 3 at one end of the mandrel 1, and install the lower hoop 8 of the rubber hoop onto the positioning disc 3, so that the spherical stopper 4 inside the lower hoop 8 of the rubber hoop is closely aligned with the groove 13 on the positioning disc 3. Cooperate well, and the screw 9 is screwed in the positioning hole 6, and the stabilizing body 5 is welded on the lower end of the mandrel. When vulcanizing, put the rubber tube 10 into the mandrel 1, make one end of the rubber tube 10 fit closely with the positioning boundary 11, and then install the rubber hoop 2 on the other end of the m...

Abstract

The invention relates to a rubber band core rod processing device without stub bars. The device consists of a core rod, a lower rubber band, an upper rubber band, a spherical baffle block, a locating disk and a screw, wherein, a groove is arranged on one end of the core rod and is correspondingly assembled with and fixed to a boss of the upper rubber band, and an endpoint of a hose is located; and the locating disk is arranged on the other end of the core rod and is equipped with a locating hole, a locating groove and a hose locating interface, the other end of the hose and the locating disk are sequentially located according to the hose locating interface, the locating groove of the locating disk and a boss of the lower rubber band are assembled and fixed together correspondingly, and the locating hole on the locating disk is locked by the screw so that the locating disk is fixed on the core rod. Through the adoption of the rubber band core rod processing device, the stub bars on two ends of the original hose are not used any more; the operation procedure of cutting off the hose is not needed, thus saving precious cost of unit production time; and the outer diameter of two ends of the vulcanized finished hose can be controlled, thus greatly improving the dimensional precision and the qualification rate of the product and avoiding waste of raw materials.

Description

technical field [0001] The invention relates to a clamp for a processing device of a rubber hose for automobiles, in particular to a processing device for a mandrel with a rubber hoop without a head. Background technique [0002] At present, in the production process of the rubber hose, after the rubber hose is vulcanized, it is necessary to cut off the excess material at both ends of the rubber hose. The main reason is that the rubber hose will shrink during vulcanization, and the shrinkage ratio is not easy to control, so the vulcanized product is longer than the actual one, and then the excess part is cut. The rubber hose produced by the current production method will not affect the use of the product, but will waste raw materials and increase the cost. In today's world where resources are limited, savings are unlimited, and the development of a conservation-oriented society is advocated, it is obvious that it is necessary to control the waste of raw materials, so the ru...
