In order to achieve the purpose, the utility model develops a punching tool switching device, which realizes punching of different contents through two sets of gas circuits. One set of the pneumatic punching mechanism is a main punching cylinder air passage, and a pressure plate and a male die mechanism which are arranged on the linear guide slide rail are driven to realize punching through a large-tonnage pneumatic punching cylinder. The other set is a punch switching gas circuit, a gap is reserved between the punch and the punching cylinder, and a small cylinder is adopted to drive the wedge-shaped sliding plate to fill or leave the gap, so that the ejection and the recovery of the punch are realized, and the punch switching of different configurations is realized.
The utility model comprises a fixed base, a clamp base plate, a positioning mechanism, a main punching cylinder, a male die, a female die, a pressure plate, a linear guide slide rail, a switching device, a switching cylinder and a wedge-shaped slide plate;
the fixed base is arranged on the ground through foundation bolts, and the clamp base plate is fixed on the fixed base;
the main punching cylinder is installed on the surface of the clamp base plate.
The linear guide sliding rail is arranged on the surface of the clamp base plate and is used for assisting the punching mechanism to slide back and forth.
The pressure plate is arranged on the linear guide sliding rail and connected with the main punching cylinder and used for fixing and clamping the parts.
The male die and the limiting device are arranged inside the material pressing plate.
The switching device is arranged at the upper part of the material pressing plate; the switching device comprises a switching cylinder and a wedge-shaped sliding plate; the switching of punching holes with two configurations is realized by driving the wedge-shaped sliding plate to extend and retract through the switching cylinder.
The profiling block is arranged on the surface of the clamp substrate.
The positioning mechanism realizes the positioning of the part to be punched, adopts a positioning pin and a positioning surface structure, and is arranged on the contour block and used for positioning the part to be punched.
The female die is arranged on the contour block, and the position of the female die corresponds to that of the male die.
The utility model has the advantages that:
the utility model discloses the accessible gas circuit is instant, quick (time is less than 1S) switches, need not the many sets of frocks of multichannel process, also need not to carry out manual switching such as die, pressure flitch. The button box can be directly used for realizing automatic switching simply and conveniently.
Drawings
Fig. 1 is a mechanism diagram of the switching type punching table of the present invention.
Fig. 2 is a schematic view of the switching mechanism of the punching table of the present invention.
Detailed Description
Referring to fig. 1 and 2, the present invention includes a fixing base 1, a clamp base plate 2, a positioning mechanism 3, a main punching cylinder 4, a male mold 5, a female mold 6, a pressure plate 7, a linear guide slide rail 8, a switching device 9, a switching cylinder 10 and a wedge-shaped slide plate 11;
the fixed base 1 is arranged on the ground through foundation bolts, and the clamp base plate 2 is fixed on the fixed base 1;
the main ram 4 is attached to the surface of the jig base plate 2.
The linear guide rail 8 is mounted on the surface of the jig base plate 2 to assist the forward and backward sliding of the punching mechanism.
The pressure plate 7 is arranged on the linear guide sliding rail 8, and the pressure plate 7 is connected with the main punching cylinder 4 and used for fixing and clamping parts.
The male die 5 and the limiting device 12 are arranged inside the pressure plate 7.
The switching device 9 is arranged at the upper part of the material pressing plate 7; the switching device 9 comprises a switching cylinder 10 and a wedge-shaped sliding plate 11; the switching of punching holes with two configurations is realized by driving the wedge-shaped sliding plate 11 to extend and retract through the switching cylinder 10.
The contour block 13 is mounted on the face of the jig base plate 2.
The positioning mechanism 3 realizes the positioning of the part to be punched, adopts a positioning pin and a positioning surface structure, and the positioning mechanism 3 is arranged on the contour block 13 and is used for positioning the part to be punched.
The female die 6 is arranged on the contour block 13, and the position of the female die 6 corresponds to that of the male die 5.
The utility model discloses a working process:
as shown in fig. 1, the utility model discloses to punch a hole the mechanism and fix on unable adjustment base 1, the last anchor clamps base plate 2 that is equipped with of unable adjustment base 1, each positioning unit installs on the face of anchor clamps base plate 2, uses the main jar 4 that dashes of 2 tons of specifications to do main drive power.
The parts are fixed on the profiling supporting block 13 through the positioning mechanism 3.
The main punching cylinder 4 is controlled to work through the main air path, the cylinder shaft of the main punching cylinder 4 moves forward to drive the pressure plate 7 on the linear slide rail 8 to start moving forward, when the pressure plate 7 is in contact with a workpiece, the spring inside the pressure plate 7 is compressed, the pressure plate 7 stops moving forward, the punch of the male die 5 continues moving forward and punching into the female die 6, when the limit 12 of the punching table starts working, the main punching cylinder 4 reaches a stop position, and the punching work is completed. And controlling the retraction of the main flushing cylinder 4 through the air path again, and finishing the working procedure.
Fig. 2 shows a punching table switching device 9. A12 mm gap is reserved between the punch and the main punching cylinder 4. The upper part is provided with a switching cylinder 10, and the shaft of the switching cylinder 10 is provided with a wedge-shaped sliding plate 11. The air passage is used for controlling the switching cylinder 10 to extend out to drive the wedge-shaped sliding plate 11 to be plugged into the gap, so that the switching punch also works when the main punching cylinder 4 works.
When the air circuit control switching cylinder 10 retracts, the wedge-shaped sliding plate 11 is driven to slide out of the gap, and when the main punching cylinder 4 works, the punch does not advance to punch holes due to the fact that a gap is formed in the rear portion of the punch. Therefore, the in-out switching of the punch is realized, and further the punching processes with different configurations are realized.
