Detailed Description

The embodiment of the present invention will be described with reference to the accompanying drawings, and as shown in fig. 1, a withholding machine with an automatic pressure maintaining function is characterized by comprising a cabinet (1), a withholding machine cylinder (2), a motor (3), a hydraulic cylinder, a plurality of groups of hydraulic pipes, a plurality of electromagnetic hydraulic valves (4), a mold, a start button (k 1), a process parameter adjusting knob (k2), and a control module; the control module is electrically connected with the motor (3), the electromagnetic hydraulic valve (4), the starting button (k 1) and the process parameter adjusting knob (k 2). The control module comprises any controller of a PLC and a singlechip.

When the automatic pressure maintaining device works, a worker inputs a proper value through a process parameter adjusting knob (k2) according to the process requirement of a workpiece, the controller determines the pressure maintaining time through comparison with the stored process parameter based on the input value, after the worker presses a starting button (k 1), the controller can automatically work through controlling the action of a motor and an electromagnetic valve, and can accurately control the pressure value and the pressure maintaining time, and the pressure curve is shown in the following figure 4.

When the same type of workpieces are continuously machined, a worker only needs to input process parameters once, then the workpieces are machined each time, and all the operation procedures can be completed only by pressing a button once after the workpieces to be machined are in place. In order to further control the pressure precision, an electromagnetic flow valve can be selected, so that the pressure on the workpiece can be controlled more accurately.

Still include foot switch (5), with start button (k 1) function is unanimous for liberation workman's both hands promote work efficiency. However, when the foot control switch (5) is placed on the ground, if no obvious reminding is given, the false touch is easy to cause, and the personal injury can be seriously caused.

Therefore, the utility model designs a low-cost reminding scheme, and a containing groove (11) of the foot control switch (5) is arranged on the cabinet (1); a reminding lamp belt (51) is arranged on the foot control switch (5). Accomodate recess (11) with foot switch (5) are trapezoidal, accomodate the recess and slightly be greater than in height foot switch (5), foot switch (5) top is provided with switch (k 3) that outwards popped out, works as foot switch (5) are placed when accomodating recess (11), switch (k 3) are by the recess wall extrusion, remind lamp area (51) to close, work as foot switch (5) are followed when taking out during accomodating recess (11), switch (k 3) break away from the recess wall extrusion, are opened by the bullet under the effect of spring, remind lamp area (51) to open.

The functions can be realized through sensor design such as a proximity switch, or a specific protrusion is arranged on the storage groove (11), the protrusion is used for prompting a switch (k 3) of the lamp strip (51) on the foot control switch (5), when the foot control switch (5) is taken out of the storage groove, the switch of the lamp strip (51) is activated, and the lamp strip (51) is normally on. As shown in fig. 5, the protrusion may be an insulating sheet, and when the foot control switch (5) is placed in the accommodating groove, the protrusion is inserted into a circuit of the reminding lamp strip (51), and the reminding lamp strip (51) is controlled by the blocking circuit.
