Description
Technical Field
The invention belongs to the technical field of roller structures, and particularly relates to a press special for producing high-strength escalator rollers.
Background
Along with economic development, more and more public places set up automatic escalator, if at airport, railway station, subway station and market, automatic escalator convenient to use is swift, receives liking of passenger deeply. Because the escalator circularly rotates in a chain type rolling manner, a large number of rollers are needed to be used for supporting rotating parts of the escalator, and because the escalator is generally used in occasions with large passenger flow, the escalator generally rotates continuously and plays an important role as the rollers for ensuring the safe operation of the escalator. Most of elevator rollers in the existing market are made of metal, the manufacturing cost of the metal rollers is very high, certain noise can be generated during use, the wear resistance is poor, and the damage rate is very high. Some elevator rollers also have an elastic wear-resistant layer which is formed by injection molding on the cylindrical surface of a metal rolling bearing, but the process of injection molding the wear-resistant layer on the metal is difficult to realize kneading firmness and is easy to fall off when in use.
In the prior art, patent publication No. CN108502690B "a high-strength escalator roller" provides a high-strength escalator roller, which can achieve the purpose of high-strength connection between the roller and the roller shaft by arranging a clamping disc unit, a connecting column unit and an electromagnet unit on the inner ring of the roller. The structure has the defects of complex process, high cost and the like.
In addition, in the prior art, in the manufacturing process of the rubber-coated roller, the rolling bearing needs to be pressed into the wear-resistant bearing wrapping ring. The previous process needs a large amount of manual operation, the production efficiency is low, and the quality is difficult to ensure.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the press which is special for escalator roller production and has a simple and efficient structure. The technical scheme of the invention is as follows:
the utility model provides a press of staircase gyro wheel production which characterized in that: the device consists of a hydraulic cylinder 10, a pressure rod 20, a pressure head 30, a storage table 40, a support 50 and a controller. The pressure rod 20 is connected to a piston rod 60 of the hydraulic cylinder 10. The pressure head 30 is located at the bottom end of the pressure lever 20 and is in a cone-shaped structure. The object placing table 40 is located under the pressure head 30, and the center of the object placing table 40 and the center of the pressure head 30 are located on the same vertical line. The center of the object placing table 40 is provided with a hole 70. The diameter of the hole 70 of the object placing table 40
Greater than the inner diameter of the bearing ring
Smaller than the outer diameter of the bearing wrapping ring
The diameter of the object placing table 40
Not less than the outer diameter of the bearing packing ring
Has the advantages that:
the press special for escalator roller production improves the rubber coating operation speed, improves the rubber coating roller production efficiency, reduces labor, and has stable rubber coating quality.

Detailed Description
The invention is further described with reference to the following figures and specific examples.
As shown in fig. 1, the escalator roller structure of the embodiment is schematically illustrated. The escalator roller wheel of the embodiment is composed of a bearing wrapping ring 1 and a rolling bearing 2, wherein the inner diameter phi 3 of the bearing wrapping ring 1 is smaller than the outer diameter of the rolling bearing 2, and the difference between the inner diameter phi 3 of the bearing wrapping ring 1 and the outer diameter of the rolling bearing 2 is 2mm-5 mm; the bearing retainer 1 is made of thermoplastic elastic plastics. The section of the bearing retainer ring 1 is concave, the rolling bearing 2 is matched with the bearing retainer ring 1, and part of the ring body of the rolling bearing 2 is embedded in a concave ring groove of the bearing retainer ring 1. The outer diameter phi 3 of the bearing retainer 1.
The production method of the escalator roller comprises the following specific process steps:
step one, manufacturing a wear-resistant layer: manufacturing a bearing wear-resistant wrapping ring in an injection molding machine by using a mold;
step two, pressing in: pressing the rolling bearing into the wear-resistant wrapping ring by using external force;
step three, polishing: polishing the outer surface of the wear-resistant packing ring to make the surface smoother and meet the requirement of the required overall outer diameter;
step four, checking: and (5) carrying out smoothness and size inspection.
The press special for escalator roller production in the embodiment comprises a hydraulic cylinder 10, a pressure rod 20, a pressure head 30, a placing table 40, a support 50 and a controller. The pressure rod 20 is connected to a piston rod 60 of the hydraulic cylinder 10. The pressure head 30 is located at the bottom end of the pressure lever 20 and is in a cone-shaped structure. The object placing table 40 is located under the pressure head 30, and the center of the object placing table 40 and the center of the pressure head 30 are located on the same vertical line. The center of the object placing table 40 is provided with a hole 70. The hydraulic cylinder 10 and the object placing table 40 are both mounted on the bracket 50. The diameter of the hole 70 of the object placing table 40
Greater than the inner diameter of the bearing ring
Smaller than the outer diameter of the bearing wrapping ring
The diameter of the object placing table 40
Not less than the outer diameter of the bearing packing ring
The working principle is as follows:
the press of this embodiment is composed of a hydraulic cylinder 10, a pressure lever 20, a pressure head 30, a placing table 40 and a support 50. The bearing ring 1 is placed in the center of the object placing table 40, and the rolling bearing 2 is placed in the center of the bearing ring 1. The hydraulic cylinder 10 is started, the piston rod 60 drives the press rod 20 to move downwards, the press head 30 pushes the rolling bearing 2 to move downwards, and finally the rolling bearing 2 is pressed into the bearing wrapping ring 1. The piston rod 60 stops moving downward and moves upward, thereby lifting the plunger 20. And finishing the encapsulation operation.
