specifically, according to the technical scheme of the embodiment, after the mold head 5 is taken out through the quick-change handle 10, the new mold head is placed through the quick-change handle 10 to enable the positions of the annular pin 8 and the limiting hole to correspond to each other one by one, the control platform controls the sliding block to shrink to fix the mold head 5 and the mold base 3, the replacement process of the mold head 5 is completed, and compared with an operation mode of completely depending on manual experience and hand feeling, the operation mode is more accurate and rapid.
in another specific embodiment of the present invention, the control platform is further configured to obtain a buckling instruction, obtain the size of the outer diameter of the finished product to be buckled in real time after the buckling instruction is obtained, and control the movement of the slider to make the aperture surrounded by the mold head and the outer diameter of the finished product have the same size after the outer diameter of the finished product is obtained.
specifically, the movement of the slide block (the upper seat body 1 or the lower seat body 2) causes the die seat 3 to contract or expand, wherein the distance that the slide block moves in the vertical direction and the distance that the die seat 3 contracts, that is, the size of the aperture surrounded by the die head 5, have a corresponding relationship, that is, the distance that the slide block moves in the vertical direction and the distance that the die head 5 forms (for accommodating a metal head) contracts have a proportional relationship, and this relationship is determined by the die seat 3 and the shape in contact with the seat body, for example, when the angle formed by the sliding contact surfaces of the die seat 3 and the seat body is 135 degrees (45 degrees from the vertical direction), the distance that the slide block moves in the vertical direction is equal to the distance that the die seat contracts, so that the size of the aperture formed by the die head can be adjusted by controlling the distance that the slide block moves.
As the implementation of above-mentioned embodiment, withhold the outer diameter of finished product and be the distance of the diameter + fine setting of mould, the position of slider can be gathered every 2 milliseconds to control platform, in case withhold to the external diameter size of settlement, control platform will control the drive arrangement of slider and get into the static pressure state to open after the static pressure is accomplished, and control platform can carry out corresponding storage to the external diameter size of this model product and make things convenient for next use, directly call when using next time can. The control platform also gives corresponding prompts. Wherein, the precision of the size of the external diameter of the buckled finished product is 0.1 mm. Can meet the requirements of most application environments.
Refer to the withhold in-process control flow diagram that fig. 7 shows, detect the position of slider in real time at the position sensor of withholding concrete implementation in-process, set up certain reserve volume, control withhold drive arrangement and carry out quick motion when the distance in mould aperture is greater than withholding off-the-shelf external diameter 4 millimeters, realize the quick shrink of mould and save time, and get into at a slow speed after being less than 4 millimeters and withhold, realize accurate withholding when avoiding the mould damage, and the mould aperture is the same with withholding off-the-shelf external diameter again, it gets into static pressure holding state and fixes the metal button after, the expansion mould takes out the finished product after withholding and accomplishes this withholding.
In some embodiments of the present invention, the control platform may comprise a main controller, a display, an alarm, and a button, the main controller is used for driving a slider of the crimping machine, the position sensor is connected to control corresponding actions, the display may display corresponding operating states and conditions, the driving device of the slider of the crimping machine generally comprises an oil cylinder and a piston, the piston is driven by the oil cylinder to move, and the slider connected to the piston moves to crimp, which requires monitoring of the oil temperature of the oil cylinder
Further comprising: and the temperature sensor is used for monitoring the oil temperature in the oil cylinder of the crimping machine and sending the oil temperature to the control platform, and when the control platform detects that the oil temperature is too high, the sliding block stops moving to stop crimping.
Specifically, if the system pressure is small due to the fact that the oil temperature is too high, and the buckling is not in place or the buckling pressure is not in place due to the fact that the force required by buckling the pipe is larger than the highest pressure of the system, the system keeps high-pressure delay time at a high-pressure position, the buckling is automatically stopped after unit second, and meanwhile, the touch screen prompts that the buckling is not in place at this time. Otherwise, the buckling is stopped when the buckling is successfully in place.
In other embodiments of the present invention, the control platform may also perform real-time monitoring on other sensors in each crimping machine, and if there is an abnormal situation, the control platform may immediately send an alarm prompt message through a display screen or other alarm devices to perform corresponding reminding. And the input and the output of other switching values in the crimping machine are also displayed in real time, so that the user can conveniently and quickly maintain the crimping machine. The control system also has an automatic shutdown function, and the control platform enters a standby state to save electric energy when not receiving any operation instruction or data input by the keys within a fixed time.
Referring to fig. 5, as a specific implementation manner of the present invention, the gate frame 11 and the slide block 12 as shown in the figure may be used to form an accommodating space of the mold base, and the integrated design form of the gate frame 11 has higher strength, so as to meet the requirement of higher pressure strength of the product.
And a gasket 6 is arranged between the die seat and the door-shaped frame or between the upper seat body and the lower seat body, so that the die seat is prevented from being worn, and the durability of the die seat is improved.
