Abstract
The utility model discloses a pneumatic punch with overload protection function, which comprises a punch driving mechanism, a piston, a sliding block and a pressure gage, wherein the piston is connected with the punch driving mechanism by a connecting rod, the piston and the sliding block form a punch head oil cylinder, the pressure gage is communicated with the punch head oil cylinder, the pneumatic punch is characterized in that an overload protection device is arranged between the punch head oil cylinder and the pressure gage and is respectively connected with the punch head oil cylinder and the pressure gage through pipelines. The pneumatic punch with the overload protection function has a simple structure, is convenient to operate and ensures operating personnel to timely find the punch overload situation through the overload protection device between the punch head oil cylinder and the pressure gage, can quickly carry out the shutdown and reset operation, so that the quality of workpieces is ensured, the damage to the equipment is effectively avoided, the source material is saved and the production efficiency is ensured.
Description
Technical field
The utility model relates to a kind of punching machine structure, especially relates to a kind of structure with Pneumatic press of overload protection function, belongs to the technology of die manufacturing field.
Background technology
Punch press, application is very extensive in the Machining Technology field, and it comprises the punch press fuselage body; 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, and 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.
The utility model content
In order to overcome the deficiency of prior art, the purpose of the utility model is to provide a kind of can effectively guarantee product quality, and protection punch press itself guarantees to produce the Pneumatic press with overload protection function that normally carries out in order.
The utility model is realized through following technical scheme:
A kind of Pneumatic press with overload protection function; Comprise the punch press driving mechanism, pass through piston, slide block and Pressure gauge that connecting rod is connected with the punch press driving mechanism; 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; Between drift oil cylinder and Pressure gauge, also be provided with overload protection arrangement, overload protection arrangement is connected with Pressure gauge with the drift oil cylinder respectively through 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 beneficial effect of the utility model is: the utility model is simple in structure, easy to operate; Through between drift oil cylinder and Pressure gauge, overload protection arrangement being set, making 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, practiced thrift raw material, guaranteed production efficiency.
Description of drawings
Fig. 1 is the part-structure sketch map of the utility model one embodiment.
Main Reference numeral implication does 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
To combine accompanying drawing below, specify the specific embodiment of the utility model:
Fig. 1 is the part-structure sketch map of the utility model one embodiment.
As shown in Figure 1: Pneumatic press with overload protection function; Comprise the punch press driving mechanism, pass through piston 5, slide block 6 and Pressure gauge 2 that connecting rod 4 is connected with the punch press driving mechanism; Wherein piston 5 forms drift oil cylinder 1 with slide block 6, 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 through 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, is communicated with between drift oil cylinder 1, 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 the interior pressure of drift oil cylinder 1; And when punch press transships, the 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, and its oily memory space is communicated with punch press oil cylinder 1; Reach the effect of release, 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 utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replacement or the technical scheme that obtained of equivalent transformation mode, all drop within the protection domain of the utility model.
Claims (3)
1. Pneumatic press with overload protection function; Comprise the punch press driving mechanism, pass through piston, slide block and Pressure gauge that connecting rod is connected with the punch press driving mechanism; 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; Between drift oil cylinder and Pressure gauge, also be provided with overload protection arrangement, overload protection arrangement is connected with Pressure gauge with the drift oil cylinder respectively through pipeline.
2. the Pneumatic press with overload protection function according to claim 1 is characterized in that, is provided with oily memory space in the described overload protection arrangement.
