Description

Technical Field

[0001] The utility model relates to the technical field of composite material hydraulic presses, in particular to a composite material hydraulic press with a safety protection mechanism. Background Art

[0002] Composite hydraulic presses are used for compression molding of thermosetting and thermoplastic composite materials such as SMC, BMC, DMC, GMT, D-LFT, and G-LFT. The safety protection of traditional large composite hydraulic presses uses sealing plates on the left and right sides and front and rear vertical gratings to protect the operator. The grating will be triggered during the loading and unloading process of the hydraulic press. The operator needs to manually determine the safety when operating the equipment again. Press the grating reset button, and the front and rear vertical gratings will detect whether there are any obstructions in the two vertical directions. After confirming that there are no obstructions in the two vertical directions, the electronic control system will release the grating alarm, and the operator will press the down button of the hydraulic press. The hydraulic press will move down and automatically complete the action set by the program.

[0003] However, it still has the following disadvantages in actual use:

[0004] Since the safety protection of traditional large-scale composite hydraulic presses mostly requires manual observation, judgment and operation, there are great safety hazards in manual judgment of safety. There are blind spots in the operator's operating position when viewing the entire working area, and the molds placed in the working area will also have a certain impact on the operator's line of sight.

[0005] Therefore, a new composite hydraulic press with a safety protection mechanism is proposed to solve the above problems. Utility Model Content

[0041] The protection assembly 2 also includes a sealing plate 28 fixedly connected to the upper ends of both sides of the rolling shutter frame 21 and an air outlet 29 opened at the outer side of the sealing plate 28;

[0042] The hydraulic assembly 1 also includes a hydraulic press 12 fixedly connected to an inner position of the outer shell 11;

[0043] The outer surface of the linear guide rail 24 has a slide groove opened relative to the slide group 25, and the laser scanner 27 is composed of two groups of identical structures;

[0044] The vertical safety grating 23 is located on the inner side of the rolling shutter frame 21, and the vertical safety grating 23 does not contact the rolling shutter door 22;

[0045] The air outlet 29 is connected to the interior of the outer shell 11, and an exhaust fan is fixedly installed on the outer end surface of the air outlet 29;

[0046] Working principle:

[0047] The unused areas at the high places on both sides of the hydraulic press 12 are fixed with sealing plates 28, and an exhaust port 29 is opened on the top to extract the waste smoke and waste gas generated during the pressing process for subsequent treatment.

[0048] Rolling shutter doors 22 and vertical safety gratings 23 are installed on the front and rear sides. The vertical safety gratings 23 are installed on the inner side of the rolling shutter frame 21. Before loading and unloading, the rolling shutter door 22 is quickly opened to allow operators to enter the working area of ​​the hydraulic press 12; when the hydraulic press 12 moves up and down, the rolling shutter door 22 is closed, and operators are not allowed to enter the inner side of the outer shell 11. A laser scanner 27 is installed on the outer side of the hydraulic press 12 to monitor the lateral area in the working area. The laser scanner 27 can be adjusted up and down within a certain range according to the mold height to be about 20mm higher than the lower mold. Before the hydraulic press 12 moves, the laser scanner 27 monitors the lateral area. The lateral area can be programmed through software to detect whether there is any obstruction in the working area of ​​the hydraulic press 12 (there are maintenance tools on people or the lower mold). After confirming that the working area is safe, the hydraulic press 12 performs relevant actions to ensure the safety of personnel and avoid misoperation caused by the failure to remove the maintenance tools, effectively protecting the mold and extending the service life of the mold.

[0049] This step improves the safety and reliability of large composite hydraulic presses, meets environmental protection requirements, and optimizes the operating environment for operators.
