Description

Technical Field

[0001] This utility model relates to the field of integrated training technology for hydraulic transmission of presses, specifically to an integrated training system for hydraulic transmission of presses. Background Technology

[0002] Regarding the teaching of hydraulic transmission integrated experimental platforms, existing equipment focuses on the most basic hydraulic principles and the pure theoretical introduction and experiments of hydraulic circuits. The operation of hydraulic components is mostly manually controlled, which prevents students from keeping up with societal developments and truly experiencing the convenience brought by automation. Most teaching equipment emphasizes basic knowledge while neglecting related supporting facilities, making it impossible to truly grasp the equipment conditions in actual factories through practical training. Therefore, we have invented a comprehensive hydraulic transmission training system for presses. Utility Model Content

[0003] The purpose of this invention is to provide a comprehensive training system for hydraulic transmission of a press, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A comprehensive training system for hydraulic transmission of a press includes a test bench. A chassis is placed at the right end of the test bench, and a keyboard and display screen are located at the bottom right end of the test bench. The chassis, keyboard, and display screen are connected. A control panel and hydraulic control components are mounted on the top of the test bench, and both the control panel and hydraulic control components are connected to the chassis.

[0006] It also includes a press model installed on the top left end of the test bench. The press model includes a lower crossbeam, which is fixedly installed on the top of the test bench. Columns are fixedly installed at the four corners of the top of the lower crossbeam. An upper crossbeam is fixedly installed on the top of the columns. A movable crossbeam is slidably connected in the middle of the columns.

[0007] A lower mold is installed at the top of the lower crossbeam, and an upper mold is installed at the bottom of the movable crossbeam;

[0008] An upper hydraulic cylinder is fixedly installed in the middle of the upper crossbeam. The output end of the upper hydraulic cylinder is vertically downward and fixedly connected to the movable crossbeam.

[0009] The upper crossbeam is also equipped with a filling tank and a replenishing oil tank, both of which are connected to the upper hydraulic cylinder.

[0010] The lower crossbeam has a hole in the middle and a lower hydraulic cylinder is installed thereon. The output end of the lower hydraulic cylinder is vertically upward and connected to the ejector block of the lower mold.

[0011] In a preferred embodiment of this utility model, a T-shaped mounting groove is provided on the top of the lower crossbeam, and the lower mold is fixed on the T-shaped mounting groove by a pressure plate.

[0012] In a preferred embodiment of this utility model, guide sleeves are fixedly installed at the four corners of the movable crossbeam, the inner wall of the guide sleeves is connected to the column, and a T-shaped mounting groove is provided at the bottom of the movable crossbeam. The upper mold is fixed to the T-shaped mounting groove by a pressure plate.

[0013] In a preferred embodiment of this utility model, the upper hydraulic cylinder, filling tank, replenishing oil tank and lower hydraulic cylinder are electrically connected to the control panel and control hydraulic components.

[0014] In a preferred embodiment of this utility model, a transparent cover is provided on the outside of the press model.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] In most hydraulic test benches, the hydraulic circuit function is achieved by using the extension and retraction of two single / double piston rod hydraulic cylinders to simulate the switching principle of an electromagnetic directional valve, and the speed of the action to simulate the adjustment of the pressure of a pressure valve and the speed regulation of a speed control valve. However, in reality, the actions ultimately achieved by all hydraulic components and the electrical control system working together are intuitive and visible, such as the stamping action of a press on a product and the straightening action of a bent product.

[0017] Our company's press hydraulic transmission integrated training system integrates hydraulic, PLC electrical control and hydraulic simulation technology. In addition to meeting professional training teaching, it can also carry out skills assessment. Through project-based training, it can cultivate students' professional abilities such as hydraulic pump station installation and debugging, hydraulic system assembly and debugging, electrical control technology, PLC application technology and hydraulic and pneumatic system operation and maintenance.

[0018] Moreover, through the physical movement of the miniature model of the press, trainees can clearly and intuitively see that the functions of different hydraulic components can be directly demonstrated in the moving parts of the press through the control of the hydraulic circuit, just like being in the production site of an enterprise.

[0019] This utility model makes the hydraulic circuit more intuitive, simple, and modular, combines hydraulics and electricity, and also incorporates a training platform for a three-beam four-column hydraulic press simulation device.

[0020] The modular structure design allows modules to operate independently or be combined into a comprehensive control system, facilitating equipment upgrades and expansions.

[0021] Because the overall design adopts a modular approach, various functional modules can be added to it.

[0022] Adding a physical model of the hydraulic press provides a visual demonstration of the operation process, making it easier for users to understand the functions that each hydraulic circuit is meant to perform. Attached Figure Description

A movable crossbeam 300 is slidably connected in the middle of the columns 200.

[0031] The lower crossbeam 100 is equipped with a lower mold 500 at its top, and the movable crossbeam 300 is equipped with an upper mold 600 at its bottom.

[0032] An upper hydraulic cylinder 700 is fixedly installed in the middle of the upper crossbeam 400. The output end of the upper hydraulic cylinder 700 is vertically downward and fixedly connected to the movable crossbeam 300. The upper hydraulic cylinder is a piston-type double-acting cylinder. When the pressurized oil enters the upper working chamber, the piston drives the crossbeam to move downward. Its speed is slow and the pressure is high. When the pressurized oil enters the lower working chamber, the piston moves upward. Its speed is faster and the pressure is lower, which meets the general process requirements of slow pressing and fast return.

[0033] The upper crossbeam 400 is also equipped with a filling tank 710 and a replenishing oil tank 720, both of which are connected to the upper hydraulic cylinder 700.

[0034] The lower crossbeam 100 has a hole in the middle and a lower hydraulic cylinder 800 is installed thereon. The output end of the lower hydraulic cylinder 800 is vertically upward and connected to the ejector block of the lower mold 500. The lower hydraulic cylinder is provided on the lower crossbeam and the formed part can be ejected by the ejector rod.

[0035] The lower crossbeam 100 has a T-shaped mounting groove 110 at its top, and the lower mold 500 is fixed to the T-shaped mounting groove 110 by a pressure plate.

[0036] Guide sleeves 310 are fixedly installed at the four corners of the movable crossbeam 300. The inner wall of the guide sleeve 310 is connected to the column 200. The bottom of the movable crossbeam 300 is provided with a T-shaped mounting groove 320. The upper mold 600 is fixed to the T-shaped mounting groove 320 by a pressure plate. The holes on the four corners of the movable crossbeam are fitted onto the four columns and connected to the upper hydraulic cylinder piston, which drives the crossbeam to move up and down. The machine body bears the entire working load during the operation of the hydraulic press.

[0037] The upper hydraulic cylinder 700, filling tank 710, replenishing oil tank 720 and lower hydraulic cylinder 800 are electrically connected to control the control panel 5 and control the hydraulic components 6.

[0038] The press model is covered with a transparent cover 900.

[0039] The hydraulic transmission integrated training system for presses consists of three main parts: a hydraulic integrated training platform, an industrial dual-pump hydraulic station, and a miniature model of a three-beam four-column hydraulic press.

[0040] The hydraulic integrated training platform mainly consists of a press model, a training platform, hydraulic component modules, a stacked valve training module, an electrical control module, hydraulic simulation software, measurement and control instruments, assembly and adjustment tools, training accessories, and a computer desk. This application mainly provides a detailed description of the press model.

[0041] The working principle of this utility model is as follows: the machine body is composed of an upper crossbeam, a lower crossbeam, and four columns; all components of the hydraulic press are installed on the machine body, wherein the upper hydraulic cylinder is installed in the middle hole of the upper crossbeam, the lower hydraulic cylinder is installed in the middle hole of the lower crossbeam, and a T-shaped mounting groove is opened on the lower crossbeam for installing the mold; the holes on the four corners of the movable crossbeam are fitted onto the four columns, and the upper part is connected to the piston of the upper hydraulic cylinder, which drives the crossbeam to move up and down. The machine body bears the entire working load during the operation of the hydraulic press.

[0042] The upper hydraulic cylinder adopts a piston-type double-acting cylinder. When the pressurized oil enters the upper working chamber, the piston drives the crossbeam to move downward. Its speed is slow and the pressure is high. When the pressurized oil enters the lower working chamber, the piston moves upward. Its speed is faster and the pressure is lower, which meets the general process requirements of slow pressing and fast return.

[0043] The movable crossbeam is the moving part of the column-type hydraulic press. It is located in the middle of the hydraulic press body. The central round hole is connected to the working piston rod of the upper crossbeam. The four corner holes move up and down under the drive of the working piston and guided by the column. The bottom surface of the movable crossbeam also has a T-shaped mounting groove for mounting molds.

[0044] A lower hydraulic cylinder is installed on the lower crossbeam, which can push out the formed part through the push rod;

[0045] The power component of a hydraulic press is a hydraulic pump, which converts mechanical energy into hydraulic energy and supplies high-pressure fluid to the upper and lower hydraulic cylinders of the hydraulic press.

[0046] A replenishing oil tank and a filling tank are installed on the upper part of the upper crossbeam. When the upper hydraulic cylinder descends rapidly, the filling tank replenishes the hydraulic oil into the cylinder in a timely manner. When returning, the oil in the cylinder returns to the filling tank through the filling valve. When the hydraulic cylinder is missing hydraulic oil due to leakage or maintenance, the replenishing oil tank replenishes the hydraulic oil into the filling tank through the liquid level controller.

[0047] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
