Abstract
The invention discloses a pneumatic punch press with an overload protecting function, and the pneumatic punch press comprises a punch press driving mechanism, a piston connected with the punch press driving mechanism by virtue of a connecting rod, a sliding block and a pressure gauge, wherein the piston and the sliding block form a plunger oil cylinder; and the pressure gauge is communicated with the plunger oil cylinder. The pneumatic punch press is characterized in that an overload protecting device is further arranged between the plunger oil cylinder and the pressure gauge; and the overload protecting device is respectively connected with the plunger oil cylinder and the pressure gauge by virtue of pipelines. The pneumatic punch press provided by the invention has a simple structure, and is convenient to operate; by arranging the overload protecting device between the plunger oil cylinder and the pressure gauge, an operator can discover the overload of the punch press in time and can quickly carry out stopping and resetting work, therefore, the quality of a workpiece is ensured, the damage to equipment is effectively avoided; raw materials are saved; and the production efficiency is ensured.
Description
Technical field
The present invention relates to a kind of punching machine structure, especially relate to a kind of structure, belong to the technology of die manufacturing field with Pneumatic press of overload protection function.
Background technology
Punch press, use very extensive in the Machining Technology field, it comprises the punch press fuselage body, and punch press fuselage body middle part caves inward and forms the workspace, and the punch press fuselage body on top, workspace is provided with the connecting rod that is connected with the piston of cylinder, the bottom of connecting rod is connected with drift, the bottom, workspace then is a workbench, and workbench is provided with the die that matches with drift, and drift is under the effect of cylinder, pump, the workpiece that is placed on the die is carried out punching press.
We know that the drift pressure overload of punch press is punch press recurrent thing in the work engineering, very easily causes the workpiece waste material this moment, or even damages punch press itself, not only wastes raw material, increases maintenance of equipment and renewal cost, also has a strong impact on production efficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind ofly can effectively guarantee product quality, protection punch press itself guarantees to produce the normal Pneumatic press with overload protection function that carries out in order.
The present invention is achieved through the following technical solutions:
A kind of Pneumatic press with overload protection function; the piston, slide block and the Pressure gauge that comprise the punch press driving mechanism, be connected with the punch press driving mechanism by connecting rod; wherein piston and slide block form the drift oil cylinder; and Pressure gauge is communicated with the drift oil cylinder; it is characterized in that; also be provided with overload protection arrangement between drift oil cylinder and Pressure gauge, overload protection arrangement is connected with Pressure gauge with the drift oil cylinder respectively by pipeline.
Further, be provided with oily memory space in the overload protection arrangement, and manometric height is higher than the height of overload protection arrangement.
The invention has the beneficial effects as follows: the present invention is simple in structure, easy to operate; by between drift oil cylinder and Pressure gauge, overload protection arrangement being set; make operating personnel can in time find the punch press overload; and can shut down rapidly and the work that resets; guaranteed the quality of workpiece; effectively avoid the damage of equipment itself, saved raw material, guaranteed production efficiency.
Description of drawings
Fig. 1 is the part-structure schematic diagram of one embodiment of the invention.
Main Reference numeral implication is among the figure: 1, drift oil cylinder 2, Pressure gauge 3, overload protection arrangement
4, connecting rod 5, piston 6, slide block.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
Fig. 1 is the part-structure schematic diagram of one embodiment of the invention.
As shown in Figure 1: Pneumatic press with overload protection function; comprise the punch press driving mechanism; the piston 5 that is connected with the punch press driving mechanism by connecting rod 4; slide block 6 and Pressure gauge 2; wherein piston 5 and slide block 6 form drift oil cylinder 1; and Pressure gauge 2 is communicated with drift oil cylinder 1; in addition; between drift oil cylinder 1 and Pressure gauge 2, also be provided with overload protection arrangement 3; overload protection arrangement 3 is connected with Pressure gauge 2 with drift oil cylinder 1 respectively by pipeline; in overload protection arrangement 3, be provided with oily memory space, and the height of above-mentioned Pressure gauge 2 is higher than the height of overload protection arrangement 3.
When punch press under normal duty; drift oil cylinder 1; be communicated with between overload protection arrangement 2 and the Pressure gauge 3; the force value that Pressure gauge 3 shows less than the punch press regulation; what promptly show is pressure in the drift oil cylinder 1; and when punch press transships; pressure moment increase in the punch press oil cylinder 1, pressure surpasses the force value of regulation, Pressure gauge 2 output alarm signals; and overload protection arrangement 3 is under the control of control system simultaneously; its oily memory space is communicated with punch press oil cylinder 1, reaches the effect of release, and overload protection arrangement 3 cuts out and being communicated with of oily memory space then; this moment machine down; after treating manual reset, start again, and normal operation.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
