[0010] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0011] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0012] like Figures 1-3As shown, the rear press device of the all-steel forming machine includes a frame. From top to bottom, the frame is equipped with an upper press roller mechanism, a middle press roller mechanism, and a lower press roller mechanism. The upper press roller mechanism includes a first base plate, to which a first linear motor module is connected. The linear motor module includes a motor, a lead screw, and a slide rail, used to drive other components to move linearly. The first linear motor module is connected to a first slide table, which moves the first slide table closer to / away from the tire body. Two rear bearing seats and two front bearing seats are fixedly connected to the first slide table. A rear bidirectional lead screw is rotatably connected between the two rear bearing seats, and a front bidirectional lead screw is rotatably connected between the two front bearing seats. The rear bidirectional lead screw is the same length as the front bidirectional lead screw and is parallel to it. A bidirectional lead screw is a lead screw with helical grooves in both directions. A servo motor is connected to each of the rear and front bidirectional lead screws via a chain connection. Two first angle adjustment units are arranged above the rear bidirectional lead screw, and the two first angle adjustment units are... The first angle adjustment unit, located on both sides of the center of the rear bidirectional lead screw, includes a rear slide block threaded to the rear bidirectional lead screw and a front slide block threaded to the front bidirectional lead screw. The rear and front slide blocks are slidably connected to the first slide table. Rotation of the rear bidirectional lead screw can move the two rear slide blocks closer to each other, and rotation of the front bidirectional lead screw can move the two front slide blocks closer to each other. A support seat is rotatably connected above the rear slide block, and a first steering plate is slidably connected above the support seat. A rotating shaft is rotatably connected to the end of the first steering plate away from the rear bidirectional lead screw, and the lower end of the rotating shaft is rotatably connected to the front slide block. A first cylinder is fixedly connected above the first steering plate, and a stabilizing bracket is slidably connected above the first steering plate. The first cylinder can push the stabilizing bracket closer to or away from the tire body. The first cylinder includes a retractable movable end, which is fixedly connected to the stabilizing bracket. A first pressing wheel for pressing the tire tread is rotatably connected to the end of the stabilizing bracket closer to the tire body. The first pressing wheel is vertically arranged.

[0013] The working principle of the upper pressure roller mechanism of this utility model is as follows: The first linear motor module drives the first slide to move closer to / away from the tire body. When the two first pressure rollers are parallel, the following actions are achieved by rotating the front and rear double-acting screws: 1. When the rear slide seat moves a greater distance than the front slide seat, the first steering plate rotates, thereby forming an angle between the two first pressure rollers, with the apex of the angle facing the tire body; 2. When the rear slide seat moves a less distance than the front slide seat, the first steering plate rotates, thereby forming an angle between the two first pressure rollers, with the apex of the angle away from the tire body; 3. When the rear slide seat moves a distance equal to the front slide seat, the first steering plate does not rotate, and the two first pressure rollers remain parallel, but the distance between the two first pressure rollers increases / decreases. After the angle adjustment is completed, the first cylinder pushes the first pressure roller closer to the tire tread. The tire body is rotated by other equipment. There is tread rubber between the first pressure roller and the tire tread, so the first pressure roller presses the tread rubber onto the tire tread.

[0014] Furthermore, the intermediate pressure roller mechanism includes a second base plate, a second linear motor module fixedly connected above the second base plate, a second slide table connected above the second linear motor module, two second bearing seats fixedly connected above the second slide table, a second bidirectional lead screw rotatably connected between the two second bearing seats, a servo motor connected to the second bidirectional lead screw via a chain connection, and two second angle adjustment units disposed above the second bidirectional lead screw on both sides of the second bidirectional lead screw. Each second angle adjustment unit includes an axial sliding seat, and the axial sliding seat is connected to the second bidirectional lead screw. The system is threaded and slidably connected to the second slide. The rotation of the second bidirectional lead screw can drive the two second angle adjustment units to move closer to or further away from each other. The end of the axial sliding seat away from the tire body is rotatably connected to the second electric push rod, and the end close to the tire body is rotatably connected to the second steering plate. The end of the second steering plate away from the tire body is rotatably connected to the second electric push rod. The second steering plate is fixedly connected to the second cylinder. The end of the second cylinder close to the tire body is fixedly connected to the support arm, which is also slidably connected to the second steering plate. The end of the support arm close to the tire body is rotatably connected to the second pressure wheel, which presses against the side of the tire body.

[0015] The working principle of the pressure roller mechanism in this utility model is as follows: the second linear motor module drives the second slide table to move closer to / away from the tire body, the second electric push rod drives the second steering plate to rotate, so that the angle between the second pressing roller and the side of the tire body changes, and the second cylinder pushes the second pressing roller to press against the side of the tire body.

[0016] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
