The invention discloses a pressure withstanding test device of a corrugated board longitudinal cutting blade. The test device consists of an upper fixing block, a lower fixing block, a blade placing disc, a blade clamp disc, a vertical driver, an ejector rod, a pressure sensor and a controller. The blade clamp disc is fixedly connected through a hole in the middle of the corrugated board longitudinal cutting blade. The blade placing disc is arranged on the upper end of an output shaft of the vertical driver, and a signal output line of the pressure sensor is connected with the controller. In the pressure withstanding test device of a corrugated board longitudinal cutting blade, the driver, the blade clamp disc and the ejector rod are adopted to apply pressure on the corrugated board longitudinal cutting blade and bend the corrugated board longitudinal cutting blade, and the pressure withstood by the corrugated board longitudinal cutting blade is recorded in real time and visually displayed by the pressure sensor and the controller.

Description
Technical field:
The present invention relates to mechanical field, relate in particular to corrugated board rip cutting blade, particularly a kind of corrugated board rip cutting blade pressure resistant testing device.
Background technology:
In the automatic tinuous production of corrugated board, the operation that cardboard is cut is finished by thin blade paper cutter, paper cutter utilizes the single cutter of high-speed driving to carry out on the assigned address of corrugated paper board production line; The speed of slitter and the speed of cardboard should be complementary.In the prior art, used thin blade is the wolfram steel alloy blade, if speed does not match or unusual condition takes place for assembling, equipment or the like when using, thin blade may be subjected to external shock load and produce shearing and moment of flexure, when its bending stress of bearing reached its yield limit, thin blade will collapse the cutter fracture; Because of blade is to be in the state of running up, the blade that the breaks accident such as hurt sb.'s feelings that may fly out.Therefore the bending strength to thin blade requires very high, promptly require blade can bear certain force value, make blade strength accomplish that its bending stress is not when reaching its designed or extreme pressure of requiring, therefore phenomenon of rupture can not take place, and the maximum pressure value desired value that thin blade moment be can bear when crooked is very crucial.But do not check the device of its withstand voltage at present.
Summary of the invention:
The object of the present invention is to provide a kind of corrugated board rip cutting blade pressure resistant testing device, described this corrugated board rip cutting blade pressure resistant testing device will solve the technical matters that can not detect corrugated board rip cutting blade withstand voltage in the prior art.
This corrugated board rip cutting blade pressure resistant testing device of the present invention is by last fixed block, following fixed block, the blade holding tray, the blade clamping disk, vertical driver, push rod, pressure transducer, controller and frame constitute, wherein, described fixed block down is arranged on the frame, described go up fixed block by a support be arranged on down abreast fixed block directly over, described vertical driver is arranged in the frame, vertically the output shaft of driver is upward through down fixed block, described blade holding tray is arranged on the upper end of the output shaft of vertical driver, be provided with a groove in the upper surface of blade holding tray, described blade clamping disk is arranged on the top of blade holding tray, the central authorities of blade clamping disk are provided with portion protruding upward, described pressure transducer is arranged on the downside of fixed block, described push rod is connected the downside of pressure transducer, push rod, the central axes of blade clamping disk and blade holding tray, the output line of pressure transducer is connected with a controller.
Further, the periphery of last fixed block, following fixed block, blade holding tray and vertical driver is provided with a protective cover.
Further, described vertical driver is made of a hydraulic cylinder, and described hydraulic cylinder links to each other with a hydraulic pump by oil circuit, and described hydraulic pump links to each other with an operating grip.
Further, described controller is a programmable controller, and described programmable controller is arranged in the switch board, and described switch board is provided with a display screen, and the signal input line of described display screen is connected with programmable controller.
Further, described support is made of two stud bolts, and described stud bolt is connected with following fixed block with last fixed block respectively at two ends up and down.
Principle of work of the present invention is: blade clamping disk, blade holding tray, down fixed block, go up parts such as fixed block, stud bolt, nut, hydraulic pump and all pacify and join with frame, thin blade to be measured is arranged between blade clamping disk and the blade holding tray, after each coupling part assembling of inspection and affirmation accurately, firmly finishes, assemble safty shield.When promoting the handle of hydraulic pump repeatedly, the hydraulic pressure of its transmission makes the bracket at hydraulic cylinder top slowly move upward, the thin blade, blade clamping disk, the blade holding tray that drive the support above it are also slowly done upward movement together, when rising to the certain altitude position, the end of push rod will contact with the protrusion end of blade clamping disk and produce pressure, and its pressure can make blade produce downward pressure and produce bending simultaneously.The actual pressure value that blade bears is obtained by the pressure transducer that is installed in push rod top.Convert force value to analog input module that voltage signal transfers to electrical control cubicles programmable controller (PLC) by pressure transducer.By the internal processes calculation actual pressure value is shown on touch-screen, and reach the pressue-graph real time record if having time and show the pressure dynamic changing process that blade bears.Along with the slowly rising of hydraulic cylinder top bracket, the pressure that its blade can bear will slowly increase thereupon; When reaching the extreme pressure of bearing, blade will burst apart suddenly.The extreme pressure that begins to set up, slowly increases until blade breakages moment from pressure is all shown and record intuitively by touch-screen, by the qualified datum line that is provided with on the screen curve, realizes judging whether blade is withstand voltage qualified automatically.After test process finishes, can remove old record, wait for test next time by the reset button on the touch screen curtain.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention adopts driver, blade clamping disk and push rod that corrugated board rip cutting blade is exerted pressure in corrugated board rip cutting blade pressure resistant testing device and makes its bending, by pressure transducer and controller the suffered pressure real time record of corrugated board rip cutting blade is also demonstrated visually, can detect and judge different size, thickness and force value that the thin blade of material can become to bear, to calibrate the withstand voltage of corrugated board rip cutting blade, provide reference when actual condition being set to the user.
