[0015] (III) Beneficial Effects

[0016] This utility model provides a fully hydraulic four-cylinder synchronous horizontal downward adjustment three-roll plate bending machine. It has the following beneficial effects:

[0017] 1. The base and crossbar are used to set the dimensions. After the test run is completed, the base is fixed by drilling and tapping to facilitate on-site installation. After the entire equipment is installed and adjusted, the base is welded to the embedded steel plate, so that the base frame is designed to be integrated front and back. Therefore, there is no need for horizontal division and bolt connection, which achieves a very compact design. No dynamic rolling force will be generated in the foundation.

The lower roller utilizes an intermediate gearbox, meaning the frame structure is enclosed. This ensures high frame stability. Four identical hydraulic cylinders raise and lower the upper rollers. Furthermore, all upper rollers operate without levers, enabling very high synchronization accuracy and facilitating later maintenance. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This is the first embodiment of the present utility model. This embodiment provides a fully hydraulic four-cylinder synchronous horizontal downward adjustment three-roll plate rolling machine, including a base 1, a support seat 2 fixedly connected to the top of the base 1, a hydraulic cylinder 3 disposed inside the support seat 2, a lower roller 4 rotatably disposed on the opposite side of the support seat 2, a tilting bearing seat 6 fixedly connected to the top of the support seat 2, an upper roller 5 rotatably disposed on the opposite side of the two tilting bearing seats 6, the ends of the hydraulic cylinder 3 and the upper roller 5 are symmetrically arranged, and one end of the upper roller 5 passes through the tilting bearing seat 6 and extends outward.

[0031] A cross 101 is fixedly welded to the bottom of the base 1, and the cross 101 is used to determine the length and is welded to the embedded steel plate. The cross 101 is arranged in a cross shape, and the material of the cross 101 is carbon structural steel.

[0032] Specifically, there are four hydraulic cylinders 3, all of which are vertically arranged and symmetrically arranged in pairs inside the support base 2.

[0033] Furthermore, through the setting of base 1 and cross 101, cross 101 serves as a dimensional guide. After the trial run is completed, it is fixed by drilling and tapping to facilitate on-site installation. After the entire equipment is installed and adjusted, base 1 is welded together with the embedded steel plate, making the base 1 frame designed as a front and rear integrated unit. Therefore, there is no need for horizontal division and bolt connection, thus achieving a very compact design. No dynamic rolling force is generated in the foundation. Only the minimum machine pit is required, achieving maximum cost savings. The symmetrical design of the machine can achieve the best bending effect and the highest precision. The symmetrical structure between the end of the upper roller 5 and the hydraulic cylinder 3 makes the device design compact. The foundation size of the device is relatively small and simple, resulting in a smaller foundation size, thereby reducing the operating cost of the device and enabling the machine to achieve the best working effect. Moreover, all four symmetrical hydraulic cylinders 3 are rodless chambers, giving the device good synchronization accuracy.

[0034] Example 2

[0035] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] The tilting bearing seat 6 is located between two hydraulic cylinders 3, and a hydraulic rod 7 is hinged to the outer surface of the tilting bearing seat 6, and the other end of the hydraulic rod 7 is fixedly connected to the support seat 2.

[0037] Specifically, the lower roller 4 is fitted with a first bearing 401 at its end, and the first bearing 401 is fixedly connected to the inner wall of the support base 2. The tilting bearing base 6 is provided with a second bearing 601 inside. One of the tilting bearing bases 6 has a through hole 602 inside. The upper roller 5 is rotatably connected to the tilting bearing base 6 through the second bearing 601. One end of the upper roller 5 passes through the through hole 602 and extends to the outside. There are two lower rollers 4, and the two lower rollers 4 and the upper roller 5 form a triangular structure. The upper roller 5 and the lower roller 4 are both made of stainless steel.

[0038] Furthermore, through the cooperation of the upper roller 5 and the lower roller 4, and using four loaded hydraulic cylinders 3, machine balance is achieved, thereby obtaining the best bending effect. The lower roller 4 uses an intermediate gearbox, which means that the frame structure is closed. This ensures the high stability of the frame. The four identical hydraulic cylinders 3 raise and lower the upper roller 5. In addition, all the upper rollers 5 operate without rods, thus achieving very high synchronization accuracy, which is convenient for later maintenance purposes.

[0039] Working Principle: During use, the base 1 and cross 101 are used. Cross 101 serves as a measuring tool. After trial operation, holes are drilled and tapped for fixation, facilitating on-site installation. After the entire machine is installed and adjusted, the base 1 is welded to the embedded steel plate, making the base 1 frame a single unit. Therefore, horizontal division and bolt connections are unnecessary, resulting in a very compact design. No dynamic rolling force is generated in the foundation, requiring only a minimal machine pit for maximum cost savings. The symmetrical machine design achieves optimal bending effect and highest precision. Furthermore, the newly developed and programmed software used in the device... The machine is controlled by hydraulic cylinders 3, lower roller 4, and upper roller 5. Through the cooperation of the upper and lower rollers 5 and the four loaded hydraulic cylinders 3, machine balance is achieved. When the upper roller 5 rotates, all four hydraulic cylinders 3 provide upward support. All four identical hydraulic cylinders 3 operate in rodless chambers, improving the synchronization of the device. Furthermore, the symmetrical arrangement of the four hydraulic cylinders 3 allows for the transmission of maximum stiffness along the shortest path of force flow, resulting in better plate rolling and optimal bending performance. The lower roller 4 uses an intermediate gearbox, meaning the frame structure is enclosed. This ensures high frame stability. The four identical hydraulic cylinders 3 raise and lower the upper roller 5. Moreover, all upper rollers 5 operate rodless, achieving very high synchronization accuracy and facilitating later maintenance.
