Abstract
The utility model discloses a hydraulic punching machine tool for steel plates. The machine tool consists of a machine tool body, a hydraulic station, and an electric control cabinet which are connected with one another, wherein a programmable logic controller (PLC) program control system is built in the electric control cabinet; the machine tool body defines an inner cavity through the top, the bottom and left and right side walls; a cylinder is fixed on the top of the machine tool body; the upper part of the cylinder is sequentially connected with an overflowing valve and an oil tank; the lower part of the cylinder is connected with a slide block through a cylinder piston rod; the slide block is arranged in the inner cavity of the machine tool body; two vertical sliding seats which can position the upper and lower travels of the slide block are respectively arranged on two side walls of the inner cavity of the machine tool body; and three induction switches, namely an upper limit switch, a pressurizing switch and a lower limit switch, which can control the travel of the slide block, are sequentially arranged on the sliding seat from top to bottom. The hydraulic punching machine tool is low in construction cost, low in energy consumption, convenient to operate, stable in punch action and high in safety.
Description
Technical field
The utility model relates to machining equipment, specifically a kind of steel plate hydro piercing lathe.
Background technology
Present automobile frame manufacturing, the processing greater than the 60mm diametric hole on the part generally has three kinds of forms: boring, cutting hole, punching.Boring can not be arrived more than the 50mm because of the radial drilling machine processing in the general vehicle frame production, need purchase in addition equipment.The cut quality of cutting hole is not high, and affects the part material performance, and efficient is low.The mechanical press that punching normal operation 200T is above, equipment investment is large, and the punch press noise is large, and security is bad.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of low-power machine that uses to be power, the steel plate hydro piercing lathe of PLC control.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of steel plate hydro piercing lathe, it is by interconnective bed piece, Hydraulic Station, the electrical control cubicles that is built-in with the PLC program control system consists of, described bed piece is by its top, bottom and left and right sides wall surround an inner chamber, top at bed piece is fixed with oil cylinder, the top of oil cylinder is connected with exuberant valve and fuel tank in turn, the bottom of oil cylinder is connected with slide block by cylinder piston rod, slide block places the inner chamber of bed piece, respectively be provided with two settings in the two side of bed piece inner chamber, the slide that can play the role of positioning to the up and down stroke of slide block, the inductive switch that from top to bottom is disposed with three control ram travels on the slide therein is upper limit position switch, add and compress switch and lower position switch.
Operation principle: by the PLC programme-control in Hydraulic Station and the electrical control cubicles, when slide block down when pressurizeing the position of the switch, thereby the oil cylinder topping up to the slide block actual punching to steel plate of pressurizeing, punching is finished rear slider and is automatically return the upper limit position switch position.
Beneficial effect: the utility model small volume and select low power oil pump motor, than large-scale punch press, saved cost; Oil pump is only just worked energy efficient when descent of piston pressurization and up backhaul; Lathe can be realized piston in any adjustment of time, stroke by PLC control and limit switch adjustment, and can realize that upper and lower stroke once finishes automatically, and is easy to operate, and than the stable action of punch press, stable, safe.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail as follows:
Referring to shown in Figure 1, a kind of steel plate hydro piercing lathe, it is by interconnective bed piece 1, Hydraulic Station 2, the electrical control cubicles 3 that is built-in with the PLC program control system consists of, described bed piece 1 is by its top, bottom and left and right sides wall surround an inner chamber 13, be fixed with oil cylinder 4 at the top of bed piece, the top of oil cylinder is connected with exuberant valve 5 and fuel tank 6 in turn, the bottom of oil cylinder 4 is connected with slide block 8 by cylinder piston rod 7, slide block places the inner chamber of bed piece, respectively be provided with two settings in the two side of bed piece inner chamber, the slide 9 that can play the role of positioning to the up and down stroke of slide block, the inductive switch that from top to bottom is disposed with three control ram travels on the slide therein is upper limit position switch, add and compress switch and lower position switch.
Hydraulic Station is realized up and down stroke and the pressurization punching of slide block by the PLC programme-control in the electrical control cubicles, and the oil cylinder upper end is equipped with exuberant valve and is communicated with fuel tank.During work, Hydraulic Station is opened closing of oil return pipe and is compressed switch according to the PLC programme-control in the electrical control cubicles, and open overflow valve, and the oil of oil cylinder lower oil cavitie is back to fuel tank, and the oil of fuel tank enters the oil cylinder upper oil cavitie, slide block is descending under Action of Gravity Field, when slide block down to adding the place that compresses switch, by the feedback of induced signal, PLC regulates and to close the flow that compresses switch, closing outflow valve, and control Hydraulic Station pump is oily to the oil cylinder upper oil cavitie, and cylinder piston rod and slide block pressurize descending under oil pressure, finish the punching to workpiece.When cylinder piston rod went downwards to the lower position switch position, PLC opened to close according to feedback signal and compresses switch, and opens overflow valve, and pump oil is to the oil cylinder lower oil cavitie simultaneously, and cylinder piston rod is up under the effect of oil pressure, realizes backhaul, and stops at the upper limit position switch place.This lathe is selected low power oil pump motor, and oil pump is only just worked energy efficient when descent of piston pressurization and up backhaul.Lathe can be realized piston in any adjustment of time, stroke by PLC control and limit switch adjustment, and can realize that upper and lower stroke once finishes automatically, and is easy to operate, and than the stable action of punch press, stable, safe.
