Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-3, the present invention is a continuous automatic stamping apparatus with a feeding device, which includes a feeding device 1, a stamping assembly 2 and a linkage driving assembly 12;
the linkage driving assembly 12 is used for driving the feeding device 1 to convey the material 4 to the punching assembly 2 when the punching assembly 2 punches the material 4.
According to the invention, the feeding device 1 and the punching assembly 2 can be linked through the linkage driving assembly 12, and when the punching assembly 2 punches the material 4, the feeding device 1 is driven to act through the linkage driving assembly 12, so that the material 4 can move while being punched, and the punching treatment efficiency of the material 4 is improved.
The linkage driving assembly 12 comprises an air supply assembly 31, a high-pressure air chamber 32 and a high-pressure air bag 33;
the punching assembly 2 comprises an upper pressing plate 21 and a lower pressing plate 22, and when the upper pressing plate 21 and the lower pressing plate 22 are close to each other, the material 4 is extruded; one surface of the lower pressing plate 22, which is close to the upper pressing plate 21, is provided with a plurality of air outlet holes communicated with the air outlet end of the high-pressure air chamber 32;
the high-pressure air bag 33 is arranged in the high-pressure air chamber 32, the air outlet end of the high-pressure air bag 33 is communicated with the high-pressure air chamber 32, and the air inlet end of the high-pressure air bag 33 is communicated with the air outlet end of the air supply assembly 31;
when the upper platen 21 and the lower platen 22 are close to each other, the air outlet end of the air supply assembly 31 is air-discharged; the air outlet end of the high-pressure air bag 33 is provided with a first one-way air outlet valve 331, the air outlet end of the high-pressure air chamber 32 is provided with a second one-way air outlet valve 321, and the limited air outlet pressure of the first one-way air outlet valve 331 is smaller than that of the second one-way air outlet valve 321.
In the present embodiment of the present invention, the air supply assembly 31 includes a stopper cylinder 311, a stopper piston rod 312, and a one-way vent 313;
the limiting cylinder 311 is fixed on the lower pressing plate 22, one end of the unidirectional piston rod is fixed on one surface of the upper pressing plate 21, which is close to the lower pressing plate 22, and the other end of the unidirectional piston rod is arranged in the limiting cylinder 311 in a sliding sealing manner;
the one-way ventilation member 313 is disposed in the piston of the stopper piston rod 312 for controlling the movement of the external air into the stopper cylinder 311.
When the upper pressing plate 21 and the lower pressing plate 22 are close to each other, the unidirectional piston rod slides in the limiting cylinder 311, gas in the limiting cylinder 311 is sent to the high-pressure air bag 33 through a pipeline built in the lower pressing plate 22, and at the moment, the high-pressure air bag 33 can lift resistance to the pressing process of the upper pressing plate 21 along with the increase of internal air pressure, so that the effect of slowing down instant buffering of the material 4 can be achieved to a certain extent.
When the air pressure in the high-pressure air bag 33 is greater than the limited air outlet pressure of the first one-way air outlet valve 331, the air outlet end of the high-pressure air bag 33 supplies air to the high-pressure air chamber 32, at the moment, the upper pressing plate 21 is in contact with the material 4, and at the moment, the instant air exhaust of the high-pressure air bag 33 can instantly reduce the resistance to the downward pressing process of the upper pressing plate 21, so that the impact force of the downward pressing of the upper pressing plate 21 is fully released;
when the air pressure in the high-pressure air chamber 32 is gradually increased, the expansion trend of the high-pressure air bag 33 is also restrained, the air pressure in the high-pressure air bag 33 is increased more rapidly at this time, so that the air is ejected more rapidly, when the air pressure in the high-pressure air chamber 32 is greater than the limited air outlet pressure of the second one-way air outlet valve 321, the air outlet end of the high-pressure air chamber 32 supplies air to the air outlet hole, at this time, the sliding stroke of the one-way piston rod in the limiting cylinder 311 can reach the maximum (the specific setting can be adjusted according to the requirement), and after the one-way piston rod reaches the maximum sliding stroke, the upper pressing plate 21 is far away from the lower pressing plate 22.
Because the pressure of the stamping can make certain adhesion exist between the material 4 made of certain materials and the lower pressing plate 22, if the material 4 is directly dragged, the material 4 may be affected in quality. Therefore, the position of the air outlet hole can be set at a position close to the material 4, and when the air outlet hole is used for discharging air, the ejected high-pressure air can form a very thin air gap between the material 4 and the lower pressure plate 22, so that the material 4 can be conveniently discharged and the feeding device 1 can be conveniently driven, and the abrasion to the material 4 is reduced.
One side of the lower pressing plate 22, which is close to the upper pressing plate 21, is provided with a limit groove 221 matched with the material 4, and an air outlet hole is formed in the limit groove 221.
The limiting groove 221 in this embodiment may be used for molding the material 4, so that the cross section of the molded material 4 and the cross section of the limiting groove 221 achieve the same effect. So, material 4 need carry and punching press in spacing groove 221, take place the scraping with spacing groove 221 more easily, and the venthole can guarantee to form very thin air gap between the groove surface of material 4 and spacing groove 221 this moment, prevents material 4 wearing and tearing, makes things convenient for material feeding unit 1 to the transport of material 4 after the shaping.
The upper platen 21 is provided with a guide cambered surface 211 on the side close to the lower platen 22. The guiding cambered surface 211 can reduce friction extrusion between the material 4 and the lower pressing plate 22 in the conveying process, and can provide a certain degree of pre-punching for the material 4, so that accidental loss of the material 4 during forming in the limiting groove 221 is avoided as much as possible. This unexpected loss is related to the shape regularity of the raw material 4 because the raw material 4 may have burrs or irregular shapes, and is easily scratched with the edge of the lower pressure plate 22 or the edge of the limiting groove 221 during traveling.
The feeding device 1 comprises a feeding roller assembly 11 and a driving assembly 12;
the driving assembly 12 is used for driving the feeding roller assembly 11 to clamp and convey the material 4.
The feeding device 1 further comprises a starting assembly;
the starting assembly comprises an elastic rotating plate 131, a first electrode 132 and a second electrode 133;
the high-pressure air chamber 32 is communicated with an air supply pipeline, the elastic rotating plate 131 is arranged in the air supply pipeline, and the air supply pipeline is communicated with the air outlet hole;
when the second one-way air outlet valve 321 is out of air, the air flow can overcome the elasticity of the elastic rotating plate 131 to jack up the elastic rotating plate 131, so that the elastic rotating plate 131 conducts the first electrode 132 and the second electrode 133, and the driving assembly 12 is started to work.
In this embodiment, before the unidirectional piston rod reaches the maximum sliding stroke, when the upper pressing plate 21 does not start to extrude the material 4, the second unidirectional air outlet valve 321 is out of air, and at this time, the feeding device 1 is started to work to rapidly convey the material 4 with better ductility, so that the material 4 can be moved in position before being stamped, and deformation of the material 4 caused by stamping and dragging the material 4 is avoided;
of course, the invention can also be set as that when the unidirectional piston rod reaches the maximum sliding distance, the upper pressing plate 21 just begins to extrude the material 4, the second unidirectional air outlet valve 321 is discharged, at this time, the feeding device 1 is started to work so as to drag the material 4 which is not easy to deform, and meanwhile, the high-pressure air flow reduces the friction between the material 4 and the upper pressing plate 21 and the lower pressing plate 22, so as to obtain the shape of the target material 4, and the situation is suitable for the stamping requirement of the material 4 with a special shape, but the stamping type of the material 4 is irregular.
A heating module is provided in the upper platen 21. The heating module and the high-pressure air outlet of the air outlet hole can form a fit, the material 4 is softened to a certain extent by heating, and the material 4 can be rapidly cooled by high-pressure air flow, so that unexpected deformation of the material 4 when being dragged is avoided.
The working principle of the invention is as follows: according to the invention, the material 4 can be dragged under the preset condition through the feeding device 1, when the upper pressing plate 21 and the lower pressing plate 22 are close to each other, the air outlet hole on the lower pressing plate 22 can spray high-pressure air flow, so that an extremely thin air gap is formed between the material 4 and the lower pressing plate 22, the dragging of the material 4 by the feeding device 1 is facilitated, and the high-pressure air flow can play other relevant roles under different punching requirements for different materials 4, so that a good and efficient punching effect can be realized under different punching requirements for different materials 4.
The foregoing describes one embodiment of the present invention in detail, but the disclosure is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
