Abstract
The invention relates to a hydraulic punching machine, comprising a hydraulic cylinder, a connector with one end arranged in the hydraulic cylinder and the other end provided with a punching member, a pressure sensor communicated with the hydraulic cylinder to detect the pressure of hydraulic oil and convert the pressure into a detection signal, a controller for receiving the detection signal and judging whether the pressure of the hydraulic oil reaches a preset pressure or not according to the detection signal as well as outputting an alarm signal when the pressure of the hydraulic oil does not reach the preset pressure, and an alarm for receiving the alarm signal and alarming after receiving the alarm signal. The invention avoids the damage to products, caused by next step, before the product is incompletely formed or by overlarge punching pressure.
Description
Technical field
The application relates to a kind of punch press, relates in particular to a kind of hydraulic press.
Background technology
Hydraulic press is as former, it is steady to have pressure, noise is little, advantages such as adjustable-speed, but pressure also often appears in hydraulic press when punching press applies situation improperly, bring hidden danger of quality for example to product, for some hand-hydraulic punch press, the operator must press " matched moulds " button and " chain " button simultaneously when mould assembling action, this measure is in order to play " fool proof " effect, avoid operator's both hands to be put into dangerous place and cause security incident, but when mould complete matched moulds on earth time the as yet, as long as there is a hand to loosen button, mould will stop matched moulds and open automatically, and product is moulding fully just.
Summary of the invention
Provide hereinafter about brief overview of the present invention, so that basic comprehension about some aspect of the present invention is provided.Should be appreciated that this general introduction is not about exhaustive general introduction of the present invention.It is not that intention is determined key of the present invention or pith, neither be intended to limit scope of the present invention.Its purpose only is to provide some notion with the form of simplifying, with this as the preorder in greater detail of argumentation after a while.
A main purpose of the present invention is to provide a kind of can avoid the improper product quality problem that causes of stamping pressure.
According to an aspect of the present invention, a kind of hydraulic press comprises:
Hydraulic cylinder;
Connector, an end is installed in the hydraulic cylinder, and the other end is used to install stamping parts;
Pressure sensor is connected with the pressure of hydraulic oil in the detection hydraulic cylinder with hydraulic cylinder, and detected pressure is converted to detection signal;
Controller is connected to pressure sensor, is used to receive detection signal, and judges according to detection signal whether the hydraulic oil in the hydraulic cylinder reaches default pressure, when the pressure of hydraulic oil does not reach default pressure in hydraulic cylinder, and the controller output alarm signal; And
Alarm is connected to controller, to receive alarm signal and to report to the police after receiving alarm signal.
The present invention is by detecting the pressure of hydraulic oil in the hydraulic cylinder, and sends warning at hydraulic fluid pressure improperly the time, and is unusual to remind operator's punching press to occur, avoided product fully moulding just carry out the excessive damage of product that causes of next process or stamping pressure.
Description of drawings
With reference to below in conjunction with the explanation of accompanying drawing, can understand above and other purpose of the present invention, characteristics and advantage more easily to the embodiment of the invention.Parts in the accompanying drawing are just in order to illustrate principle of the present invention.In the accompanying drawings, same or similar technical characterictic or parts will adopt identical or similar Reference numeral to represent.

Embodiments of the invention are described with reference to the accompanying drawings.Element of describing in an accompanying drawing of the present invention or a kind of embodiment and feature can combine with element and the feature shown in one or more other accompanying drawing or the embodiment.Should be noted that for purpose clearly, omitted the parts that have nothing to do with the present invention, those of ordinary skills are known and the expression and the description of processing in accompanying drawing and the explanation.
Please refer to Fig. 1 and Fig. 2, the better embodiment of hydraulic press of the present invention comprises hydraulic cylinder 10, connector 20 and pressure sensor 30, controller 40 and alarm 50.
One end of connector 20 is installed in the hydraulic cylinder 10, and the other end of connector 20 can be installed the stamping parts (not shown in figure 1), and connector 20 can move under the pressure effect of the hydraulic oil in the hydraulic cylinder 10, so that stamping parts carries out the punching press action.
Alternatively, pressure sensor 20 can be connected with hydraulic cylinder 10 by the joint that is communicated with, and when hydraulic cylinder 10 need be connected with miscellaneous equipment, can adopt three-way connection, as the joint among Fig. 2 60.
Alternatively, controller 40 is PLC (Programmable Logic Controller, a programmable logic controller (PLC)).
Alternatively, alarm 50 is a loudspeaker, the police whistle sound that loudspeaker can need by different mode of connection selections.
Please refer to Fig. 3, work schematic diagram for an embodiment of the present invention, among Fig. 3, start oil pump 72 by motor 71, so that oil pump 71 is extracted out from oil cylinder 73, hydraulic oil is taken out to solenoid directional control valve 76 after filter screen 74 filtrations, heat exchanger 75 condensations, and solenoid directional control valve 76 commutation back hydraulic oil flow into hydraulic cylinders 10 and carry out punching press so that connector 20 is exerted pressure, detect the pressure of punching presses during punching press by pressure sensor 40, and report to the police when improper detecting pressure.
Alternatively, pressure sensor 20 can be installed in the inside of the pipeline that connects hydraulic jack 10, as the pipeline among Fig. 3 77.
The present invention is by detecting the pressure of hydraulic oil in the hydraulic cylinder 10, and send warning improperly the time at hydraulic fluid pressure, unusual to remind operator's punching press to occur, avoided the incomplete moulding of product just to carry out the excessive damage of product that causes of next process or stamping pressure.
In equipment of the present invention, obviously, each parts reconfigures after can decomposing, make up and/or decomposing.These decomposition and/or reconfigure and to be considered as equivalents of the present invention.Simultaneously, in the above in the description to the specific embodiment of the invention, can in one or more other embodiment, use in identical or similar mode at the feature that a kind of embodiment is described and/or illustrated, combined with the feature in other embodiment, or the feature in alternative other embodiment.
