Description

Technical Field

[0001] This invention relates to the technical field of bottom hole forming equipment for tank containers, specifically to a bottom hole forming device for tank containers, and also to a forming method for the bottom hole forming device for tank containers. Background Technology

[0002] As the core transport carrier for bulk liquids, the development of tank containers is a microcosm of logistics standardization and safety technology upgrades. Tank containers mainly consist of a frame, a tank body (including two heads and a cylindrical body), and frame-tank body connecting components. The bottom hole is located at the center of the bottom of one of the heads, where a valve seat will be welded and a valve will be installed to discharge the liquid inside the tank.

[0003] Before the bottom hole is pressed, there is a certain upward curve at this position, which will leave residual liquid during drainage. After the bottom hole is pressed, the upward curve is flattened, and the residual liquid will be greatly reduced during drainage. In order to ensure the consistency of pressing and the efficiency of operation, the pressing device should be able to reach the pressing position quickly and accurately.

[0004] Chinese invention patent CN112278617A, entitled "A Tank Unloading Device and a Tank Head Opening Process," uses a spinning machine to repeatedly press vertically downwards and spin left and right to achieve the effect of flattening the bottom hole. However, this repeated pressing and multiple measurements result in extremely low efficiency and poor consistency, making it unsuitable for mass production. Furthermore, repeated pressing causes significant changes in local mechanical properties, affecting subsequent use.

[0005] Other processes involve using a wrench-like tool to manually flatten the bottom hole from both sides towards the middle, but this is inefficient, inconsistent, and requires high labor intensity for workers, and can easily damage the outer surface of the tank. Summary of the Invention

[0006] The purpose of this invention is to provide a bottom hole forming device for tank containers, which solves the problem of low bottom hole forming efficiency in the prior art.

[0007] Another object of the present invention is to provide a forming method for a tank bottom hole forming device.

[0008] The technical solution adopted in this invention is as follows: the bottom hole forming device of the tank box includes a base, a moving mechanism is connected to the base through a support component, the moving mechanism is connected to a frame, the frame is connected to a hydraulic component, the top of the hydraulic component is connected to a forming mold, and the frame is also connected to a monitoring unit. It also includes a control system, which is electrically connected to the moving mechanism, hydraulic components, and monitoring unit.

[0009] The invention is further characterized in that, The support assembly includes two support frames, both of which are connected to the base and to the moving mechanism. One of the support frames is located near the end of the moving mechanism.

[0010] The base has a groove along its length, and both support frames are set in the groove.

[0011] The moving mechanism includes a lead screw, which is connected to two support frames. One of the support frames is located near the end of the lead screw. The end of the lead screw is connected to a motor via a reducer. A lead screw nut pair is connected to the lead screw and is connected to the frame. A guide device is also connected to the bottom of the frame. The motor is connected to the control system.

[0012] The guiding device includes two parallel guide rails connected to the inner walls of the base. The length of the two guide rails is consistent with the length of the base. A guide plate is connected to the bottom of the frame. The two sides of the guide plate are respectively set inside the two guide rails. The bottom of the guide plate is connected to the lead screw and nut pair.

[0013] The hydraulic assembly includes a hydraulic cylinder, which is connected to the bottom surface of the frame, and the piston rod of the hydraulic cylinder is connected to the forming mold.

[0014] The monitoring unit includes laser emitters connected to the rack, and all laser emitters are connected to the control system.

[0015] The frame is configured as an "L" shaped mechanism. The laser emitter is connected to the inner bottom surface of the frame, the lead screw and nut pair is connected to the bottom of the frame, and the hydraulic cylinder is also connected to the inner bottom surface of the frame.

[0016] Another technical solution adopted in this invention is a forming method of the tank bottom hole forming device, which is implemented according to the following steps: Step 1. Based on the real-time feedback data from the laser emitter, the control system starts the motor, drives the frame to the first designated position, and then stops the motor. Step 2. The piston rod of the hydraulic cylinder extends, driving the forming mold to move to the front end of the bottom hole; Step 3. The frame continues to move forward, causing the forming die to move above the position to be pressed; Step 4. The piston rod of the hydraulic cylinder retracts, and the forming mold forms the bottom hole; Step 5. After the forming process is completed, the piston rod of the hydraulic cylinder rises, and the frame and hydraulic cylinder return to their original positions.

[0017] The beneficial effects of this invention are as follows: The present invention relates to a tank bottom hole forming device. The forming mechanism can accurately determine the relative position with the tank, ensuring that the forming mechanism can accurately reach the forming position. It has a high degree of automation, greatly improves efficiency, requires less human intervention, ensures the consistency of forming, and is safer and more reliable. The forming mold is easy to replace and has strong adaptability. Attached Figure Description
