Description

Technical Field

[0001] The invention relates to the technical field of ceramic manufacturing and forming equipment, and in particular to a ceramic blank rolling machine. Background Art

[0002] The rolling head of the rolling machine is fixed at the front end of the frame of the rolling machine in a form perpendicular to the frame of the rolling machine. The frame of the rolling machine swings up and down in the form of a lever, so that the rolling head swings up and down and enters and exits the ceramic container to be rolled. The rolling head cooperates with the rotation of the ceramic container to roll the middle of the ceramic container to form a ceramic container with an arc-shaped inner surface. At present, the existing ceramic blank rolling machines rely on the motor to drive the die base shaft through a V-belt or the motor drives a large cam to provide a power source for the rolling head, which causes great damage to the motor. Then, a complex mechanical brake device is used to realize the rolling cycle (rotate-stop-rotate) process, resulting in a high equipment failure rate and difficulty in maintenance. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art. The present invention provides a ceramic body rolling machine to solve the technical problems of high failure rate and great maintenance difficulty.

[0005] (II) Technical solution

[0006] The technical solution of the present invention is a ceramic body rolling machine, comprising: a first rolling head motor, a second rolling head motor, a V-shaped rolling arm composed of a first rolling arm and a second rolling arm, a first die base rolling assembly, a second die base rolling assembly and an electric control cabinet; wherein:

[0007] The first rolling head motor and the second rolling head motor are used to drive the rolling heads to roll the inside of the blank;

[0008] V-shaped rolling arm, used to adjust the stroke of the rolling head;

[0009] The first die base rolling assembly and the second die base rolling assembly are used to drive the blank to rotate;

[0010] Electric control cabinet, used for motor control and stroke adjustment;

[0011] A bearing plate is arranged on the upper part of the electric control cabinet, and the first die base rolling assembly and the second die base rolling assembly are symmetrically installed on both sides of the bearing plate. The first die base rolling assembly and the second die base rolling assembly have the same structure, and a motor support is fixedly installed in the middle of the bearing plate, and a servo motor for rotating the V-shaped rolling arm is fixedly installed on the motor support, and the first rolling arm and the second rolling arm are fixedly connected to the output shaft of the servo motor, and the first rolling head motor is installed at the end of the first rolling arm away from the servo motor, and the second rolling head motor is installed at the end of the second rolling arm away from the servo motor.

[0012] Furthermore, when the output shaft of the first rolling head motor is perpendicular to the horizontal plane, the second rolling arm forms an angle of 60° with the horizontal plane, which facilitates replacement of the blank above the second die base rolling assembly.

[0013] Furthermore, the V-shaped rolling arm can adopt an integrated structure with high stability and an angle range of 110° to 130°. When pressing conventional products, the total stroke of the first rolling arm and the second rolling arm can be greatly shortened.

[0014] Furthermore, the die base rolling assembly includes a fixing nut, a first link key, a die base, a bearing, a plane bearing, a second link key, a spindle and a spindle motor, wherein the bearing plate is fixedly connected to the spindle motor through the second link key by bolts, the second link key and the first link key are movably connected through a bearing, the spindle motor is fixedly connected to the spindle, the spindle is connected to the first link key, the top of the spindle is connected to the fixing nut, and the first link key is detachably connected to the die base by bolts; when damaged, there is no need to replace the entire die base, only components and parts need to be disassembled and replaced.

[0015] Furthermore, the second link key is detachably connected to the bearing plate through bolts, so as to facilitate the replacement of different types of mold bases.

[0016] Furthermore, a plane bearing is provided at the lower part of the bearing, so that the bearing can obtain a high load capacity.

[0017] Furthermore, the main shaft and the output shaft of the rolling head motor in the vertical direction are located on the same axis to form an integral direct drive.

[0018] Furthermore, the electric control cabinet has a built-in power supply and a Siemens PLC, and the Siemens PLC is electrically connected to the power supply and the servo motor for driving the motor to work.

[0019] (III) Beneficial effects

[0020] The advantages of the present invention are:

[0021] 1. The mold base adopts an integrated structure. The motor and the mold base spindle are on the same axis (integrated) and directly driven by a microprocessor (including industrial control PLC) to control its rotation and stop by electric control AC frequency conversion, which greatly realizes high-precision control and reduces power consumption. In addition, the mechanical structure is simple and easy to maintain.

[0022] 2. The unique design of the V-shaped rolling arm can precisely control the up and down stroke of the V-shaped rolling arm through the servo motor; for the rolling of some special-shaped ceramic bodies, the accuracy is higher. The first rolling head motor and the second rolling head motor are respectively set at both ends of the V-shaped rolling arm. The servo motor is used by the microprocessor to control the stroke, realizing double rolling head motor rolling, which is efficient and energy-saving.

[0023] 3. The first rolling head motor and the second rolling head motor are both coaxially designed with the rolling head, so that the first rolling head motor and the second rolling head motor are respectively on the same axis as the rolling head, eliminating the transmission and adjustment system. The motor driver on the motor electronically controls the speed and stops, avoiding the cumbersome material waste and high failure rate caused by the V-belt pulley, thereby achieving the effect of convenient material saving and energy saving.

[0024] 4. Microprocessor servo control rolling machine can realize adjustable working time and working stroke of all motors.

[0025] 5. Products manufactured by V-shaped rolling arms are more precise. BRIEF DESCRIPTION OF THE DRAWINGS

The die base rolling assembly 16 includes a fixed nut 6, a first link key 7, a die base 8, a bearing 9, a plane bearing 11, a second link key 12, a spindle 13 and a spindle motor 14, wherein the bearing plate 10 is fixedly connected to the spindle motor 14 through the second link key 12 by bolts, the second link key 12 and the first link key 7 are movably connected through the bearing 9, a plane bearing 11 is arranged at the lower part of the bearing 9, so that the bearing 9 can obtain a high load capacity, the spindle motor 14 is fixedly connected to the spindle 13, the spindle 13 is connected to the first link key 7, the top of the spindle 13 is connected to the fixed nut 6, the first link key 7 and the die base 8 are detachably connected by bolts, the electric control cabinet 15 has a built-in power supply and Siemens PLC (but not limited to this), the Siemens PLC is electrically connected to the power supply and the servo motor 3, and is used to drive the motor to work, with higher controllability.

[0033] Specifically, when the output shaft of the first rolling head motor 1 is perpendicular to the horizontal plane, the second rolling arm 22 forms a maximum angle with the horizontal plane (i.e., the V-shaped rolling arm 2 forms a 60° angle with the horizontal plane), which is suitable for pressing higher blanks; it is convenient to replace the blank above the second die base rolling assembly.
