Detailed Description
The invention will be described in further detail below with reference to the figures and specific examples.
An automatic temperature measurement and selection device for a casting rod for extrusion is shown in figures 1-2 and comprises a casting rod heating furnace 1, a casting rod V-shaped track 3, a support 8, a temperature measurement mechanism, a casting rod pushing mechanism 4 and a PLC (programmable logic controller) 6. The bar heating furnace 1 is used to heat the bar. The casting bar V-shaped track 3 is arranged between the casting bar heating furnace 1 and the extruder and is used for the casting bar to pass through. The bracket 8 is an inverted L-shaped bracket and is arranged at the side of the cast bar V-shaped track 3. The temperature measuring mechanism is arranged on the bracket 8 above the casting bar V-shaped track 3 and is used for measuring the temperature of the casting bar. The casting rod pushing mechanism 4 is arranged on the inner side of the bracket 8 and is used for pushing unqualified casting rods. The PLC 6 is used for controlling the temperature measuring mechanism to measure the temperature of the casting rod. The output end of the temperature measuring mechanism is connected with the input end of the PLC controller, and the output end of the PLC controller is connected with the input end of the cast rod pushing mechanism 4.
A roller way is arranged between the cast rod heating furnace 1 and the extruder, a cast rod V-shaped rail 3 is arranged on the roller way, and the heated cast rod is pushed by the cast rod heating furnace to move forwards along the roller way.
An infrared start-stop switch 5 is arranged on the inner side of the support at the front end of the cast rod pushing mechanism 4 and used for controlling the cast rod to stop advancing, and the output end of the infrared start-stop switch is connected with the input end of the PLC. When the cast rod moves to the infrared start-stop switch, the infrared start-stop switch sends a stop signal to the PLC controller to the cast rod heating furnace, and the cast rod is stopped to be pushed.
The temperature measuring mechanism comprises a thermocouple 7 and a vertical cylinder. Perpendicular cylinder sets up to 3, all sets up on the support of casting excellent V type track 3 tops, and the telescopic link of perpendicular cylinder is located casting excellent V type track 3's top, and 3 thermocouples 7 all set up the tip at perpendicular cylinder telescopic link for measure the temperature of casting excellent 2, and the input of PLC controller is connected to the output of thermocouple 7, and the controlled end of perpendicular cylinder is connected to the output of PLC controller. When the temperature of the cast rod is measured, the PLC sends a control instruction to the vertical cylinder, the telescopic rod of the vertical cylinder moves downwards to drive the thermocouple to move downwards, the temperature is measured when the thermocouple contacts the surface of the cast rod, and the measured temperature is transmitted to the PLC for analysis processing.
The support above the casting rod 2 is provided with a slide rail, the slide rail and the casting rod are arranged in parallel, the slide rail is internally provided with 3 slide blocks, the slide blocks are assembled with the slide rail, the slide blocks can move back and forth in the slide blocks, each slide block is internally provided with a driving motor for driving the slide block to move, and the controlled end of each driving motor is connected with the output end of the PLC.
An infrared induction sensor is arranged on the inverted L-shaped bracket close to the cast rod heating furnace 1 and used for detecting the tail end position of the cast rod, and the output end of the infrared induction sensor is connected with the input end of the PLC. When the cast rod moves to the infrared start-stop switch and stops, the infrared induction sensor detects the tail end position of the cast rod and sends the tail end position of the cast rod to the controller, and the controller controls the moving distance of the driving motor on the sliding block according to the distance of the cast rod, so that the thermocouples respectively detect the temperature of the head, the middle and the tail of the cast rod.
The vertical cylinder is arranged on the sliding block, when the sliding block moves, the vertical cylinder also correspondingly moves along with a follower, so that the thermocouple 7 at the end part of the vertical cylinder is driven to move, the thermocouple 7 moves left and right on the sliding rail, and the temperature of the head, the middle and the tail of the cast rod can be measured.
When the cast rod moves to the infrared start-stop switch to stop moving, the position of the tail of the cast rod is detected through the infrared induction sensor, the PLC judges the moving position of the sliding block according to the length of the cast rod, and then controls the driving motor to move to the corresponding position, so that the thermocouples are positioned at the three positions of the head, the middle and the tail of the cast rod, and the temperature of the three positions of the head, the middle and the tail of the cast rod is measured. After the sliding block moves in place, the PLC controls the thermocouple to move downwards through the vertical cylinder, the thermocouple measures the temperature when contacting the surface of the cast rod, and the measured temperature is transmitted to the PLC for analysis processing.
The pushing mechanism 4 comprises a pushing plate and a pushing cylinder. The push cylinder sets up in the inside of support 8, and the height of push cylinder is the same with the height of casting stick 2, and the push pedal setting is at the tip of push cylinder telescopic link, is used for promoting to cast the stick, and the push cylinder is used for controlling the push pedal action. The controlled end of the pushing cylinder is connected with the output end of the PLC controller. When the thermocouple detects that the temperature of the cast rod is unqualified, the PLC controls the pushing cylinder to push forwards, the cast rod is pushed to an unqualified area through the push plate, the cast rod is automatically selected, and potential safety hazards caused by manual carrying of the cast rod are avoided.
According to the working principle of the invention, after being heated in the cast rod heating furnace, the cast rod moves forwards along the roller way, when the cast rod moves to the infrared start-stop switch, the cast rod stops moving, 3 thermocouples respectively move to the head, middle and tail positions of the cast rod, the thermocouples descend and are contacted with the cast rod to measure the temperature, and the measured temperature is transmitted to the PLC for analysis. If the temperature of the cast rod meets the requirement, the cast rod continues to move forwards and enters an extruder for extrusion; and if the temperature of the cast rod does not meet the requirement, the cast rod pushing mechanism acts, and the cast rod is pushed to an unqualified area through the push plate, so that the selection work of the cast rod is completed. The invention improves the precision of the temperature detection of the cast rod, not only ensures the working efficiency, but also avoids the potential safety hazard caused by manually carrying the cast rod.
