Technical Field

[0001] The present invention relates to the technical field of stamping machines, and in particular to a stamping machine with a rapid die detection and replacement mechanism. Background Art

[0002] A stamping machine is an industrial device that applies pressure to materials through a die to form or process them. Due to its processing characteristics, it is widely used in the precision manufacturing fields of materials such as metals and plastics. Its core operation is to apply extrusion pressure to the outer side of a metal sheet through a die, causing it to undergo plastic deformation and precisely manufacturing complex-shaped parts. The dimensional error after processing and forming can be controlled within a few tenths of a millimeter.

[0003] As is well known, a stamping machine needs to cooperate with upper and lower dies to process materials. Different dies are required for different materials and products, and the dies may be damaged to varying degrees due to processing wear and improper operation. Once it is necessary to replace the manufactured product or the die is damaged, the die needs to be replaced. Currently, the die replacement for stamping machines on the market can only be completed through manual operation, which not only has low replacement efficiency but also high costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the die replacement for stamping machines on the market can only be completed through manual operation, which not only has low replacement efficiency but also high costs.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a stamping machine with a rapid die detection and replacement mechanism, including a stamping base and a reciprocating stamping head installed at the upper end of the impact base. A ring-shaped guide seat is fixedly assembled on the rear side wall of the stamping base. An electrically controlled adjustment ring is movably assembled inside the ring-shaped guide seat. A plurality of upper die mounting grooves for installing upper dies and a plurality of lower die mounting grooves for installing lower dies are opened inside the electrically controlled adjustment ring. An embedded optical detection module for detecting upper and lower dies is fixedly assembled on the inner side surface of the ring-shaped guide seat.

[0006] A bottom-mounted assembly seat for installing the lower die is fixedly assembled on the inner bottom surface of the stamping base, and a top-mounted assembly seat is axially fixed at the lower end of the reciprocating stamping head.

[0007] Electrically controlled bottom support plates are installed on the inner bottom surfaces of the upper die mounting grooves and the lower die mounting grooves. The extended ends of the electrically controlled bottom support plates are movably assembled with electrically controlled end flipping limit plates.

[0008] The electrically controlled adjustment ring includes a ring-shaped adjustment frame movably assembled inside the ring-shaped guide seat, an adjustment wheel, and a support wheel fixed inside the ring-shaped guide seat.

[0009] Inside the annular adjustment frame, electric telescopic control mechanisms are installed above the upper die mounting groove and on both sides of the lower die mounting groove.

[0010] The electric telescopic control mechanism includes an embedded adjustment guide rail, an embedded electric screw rod, an internally threaded adjustment seat, a horizontally extended cylinder, and an electric screwdriver.

[0011] A side-mounted drive cover is fixedly assembled on the annular guide seat.

[0012] Inside the side-mounted drive cover, a centrifugal drive fan and an external dust collection box are assembled.

[0013] At the upper end of the bottom-mounted assembly seat, bottom side limit seats are provided on both sides of the lower die.

[0014] Horizontally telescopic limit mechanisms are installed inside both the bottom side limit seat and the top-mounted assembly seat, and lateral limit holes matching the horizontally telescopic limit mechanisms are provided on the assembly surfaces of the upper die and the lower die.

[0015] Optical monitoring modules for monitoring the stability and position of the upper die are symmetrically installed on the inner walls of both sides of the stamping base.

[0027] The present invention will now be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8A stamping machine with a rapid die detection and replacement mechanism as shown includes a stamping base 1 and a reciprocating stamping head 2 installed at the upper end of the impact base 1. A circular guide seat 3 is fixedly assembled on the rear side wall of the stamping base 1. An electronically controlled adjustment ring 4 is movably assembled inside the circular guide seat 3. Three upper die mounting grooves 5 for installing the upper die 7 and three lower die mounting grooves 6 for installing the lower die 8 are provided inside the electronically controlled adjustment ring 4. An embedded optical detection module 9 for detecting the upper die 7 and the lower die 8 is fixedly assembled on the inner side surface of the circular guide seat 3.

[0030] To cooperate with the installation of the upper die 7 and the lower die 8, a bottom-mounted assembly seat 10 for installing the lower die 8 is fixedly assembled on the inner bottom surface of the stamping base 1, and a top-mounted assembly seat 11 is axially fixed at the lower end of the reciprocating stamping head 2.

[0031] Adjustment principle: The electronically controlled adjustment ring 4 drives the upper die 7 and the lower die 8 to perform synchronous displacement by rotating. When the displaced upper die 7 aligns with the top-mounted assembly seat 11, the corresponding lower die 8 will align with the bottom-mounted assembly seat 10. At this time, the electronically controlled adjustment ring 4 will automatically control the upper die 7 to be translated and assembled on the top-mounted assembly seat 11, and control the lower die 8 to move to the bottom-mounted assembly seat 10; Similarly, when it is necessary to replace the upper and lower dies, the empty upper die mounting groove 5 and the lower die mounting groove 6 are respectively aligned with the upper die 7 and the lower die 8 to be replaced, and then controlled to be translated and guided back into the upper die mounting groove 5 and the lower die mounting groove 6. Then, repeat the above loading process. During adjustment, the cavity dimensions of the removed upper die 7 and the lower die 8 are synchronously detected by optical scanning through the embedded optical detection module 9. The optical scanning detection method is the prior art. Then, it is judged whether the internal cavity has deformed compared with the initial data. If deformation occurs, the warning device is controlled to warn the operator to replace the unqualified die.

[0032] The lower die 8 is directly placed and supported on the upper end of the bottom-mounted assembly seat 10, and a splicing groove is provided at the upper end of the upper die 7. The upper die 7 is sleeved on the upper end of the top-mounted assembly seat 11 through the splicing groove to make the upper die 7 be spliced and fixed with the lower end of the reciprocating stamping head 2.

[0033] Infrared positioning probes are provided on the side wall of the electronically controlled adjustment ring 4 corresponding to the positions of the upper die mounting groove 5 and the lower die mounting groove 6, which is convenient for positioning in cooperation with the rotation of the electronically controlled adjustment ring 4 and improves the feeding accuracy during replacement.

[0034] To cooperate with driving the upper die 7 and the lower die 8 to translate and feed, electronically controlled bottom support plates 12 are installed on the inner bottom surfaces of the upper die mounting groove 5 and the lower die mounting groove 6. The extended ends of the electronically controlled bottom support plates 12 are movably assembled with electronically controlled end flipping limit plates 13.

[0035] The electric control type bottom support plate 12 includes bottom side guide rails installed on the inner bottom surfaces of the upper die installation groove 5 and the lower die installation groove 6, a translation lead screw installed inside the bottom side guide rails, an internally threaded translation block threadedly sleeved on the translation lead screw, and an external translation support plate fixed to the upper end of the internally threaded translation block. The internally threaded translation block and the external translation support plate are controlled to perform translation adjustment by rotating the translation lead screw.

[0036] The electric control type end flipping limiting plate 13 includes a flipping limiting plate movably installed at the extending end of the external translation support plate and a bottom side adjusting strut for controlling the flipping limiting plate. The flipping limiting plate is controlled to perform flipping adjustment by the telescopic movement of the bottom side adjusting strut, so as to facilitate controlling the separation of the die from the punching machine.

[0037] In order to cooperate with the electric control adjustment rotation, the electric control type adjusting ring 4 includes an annular adjusting frame 41 movably assembled inside the annular guide seat 3, an adjusting wheel 42 and a supporting wheel 43 fixed inside the annular guide seat 4.

[0038] In order to cooperate with the electric control telescopic adjustment, electric control type telescopic control mechanisms 14 are installed above the upper die installation groove 5 and on both sides of the lower die installation groove 6 inside the annular adjusting frame 41.

[0039] In order to cooperate with the electric control adjustment for loading and unloading, the electric control type telescopic control mechanism 14 includes an embedded adjusting guide rail 141, an embedded electric control lead screw 142, an internally threaded adjusting seat 143, a horizontally placed extension cylinder 144 and an electric control screwdriver 145.

[0040] The embedded adjusting guide rail 141 is fixed above the upper die installation groove 5 or on both sides of the lower die installation groove 6.

[0041] The embedded electric control lead screw 142 drives the internally threaded adjusting seat 143 to translate along the embedded adjusting guide rail 141 by rotation, drives the horizontally placed extension cylinder 144 fixed on the outside of the internally threaded adjusting seat 143 to perform translation adjustment, and thus drives the electric control screwdriver 145 fixed inside the horizontally placed extension cylinder 144 to perform movement adjustment, facilitating controlling the separation and tightening of the upper and lower dies.

[0042] In order to cooperate with the external function expansion, a side-mounted drive cover 15 is fixedly assembled on the annular guide seat 3.

[0043] In order to cooperate with blowing and removing impurities inside the upper die 7 and the lower die 8, a centrifugal drive fan 151 and an external dust collection box 152 are assembled inside the side-mounted drive cover 15.

[0044] The centrifugal drive fan 151 blows high-pressure air to one side inside the cavities of the upper die 7 and the lower die 8, and then blows the impurities inside the cavities of the upper die 7 and the lower die 8 into the external dust collection box 152, thus completing rapid slag removal.

[0045] To cooperate with the lateral limit and internal limit, bottom-side limit seats 16 are provided on both sides of the upper end of the bottom-loading assembly seat 10 and located on both sides of the lower mold 8.

[0046] To cooperate with the assembly limit, horizontal telescopic limit mechanisms 17 are installed inside both the bottom-side limit seat 101 and the top-loading assembly seat 11, and lateral limit holes 18 that cooperate with the horizontal telescopic limit mechanisms 17 are provided on the assembly surfaces of the upper mold 7 and the lower mold 8.

[0047] The horizontal telescopic limit mechanism 17 includes an internal transmission shaft movably installed inside the bottom-side limit seat 101 and the top-loading assembly seat 11, an internally threaded adjustment cylinder drivingly connected to the end of the internal transmission shaft, an internal adjustment screw rod threadedly inserted inside the internally threaded adjustment cylinder, and an external telescopic limit head axially fixed to the extended end of the internal adjustment screw rod.

[0048] An internal hexagonal control groove that cooperates with the electric screwdriver 145 is provided at the outer end of the internal transmission shaft, and the internally threaded adjustment cylinder is rotationally adjusted by inserting the electric screwdriver 145 into the internal hexagonal control groove.

[0049] The electric telescopic control mechanism 14 controls the end of the telescopic control electric screwdriver 145 to be inserted into the outer control end of the horizontal telescopic limit mechanism 17, and then the electric screwdriver 145 adjusts the rotation of the horizontal telescopic limit mechanism 17. The inner end of the horizontal telescopic limit mechanism 17 is inserted into the lateral limit hole 18 through extension, so that both sides of the lower mold 8 are fixedly limited with the bottom-side limit seat 101, and the upper mold 7 is fixedly limited with the top-loading assembly seat 11.

[0050] Optical monitoring modules 19 for monitoring the stability and position of the upper mold are symmetrically installed on the inner walls of both sides of the stamping base 1.

[0051] The optical monitoring module 19 monitors the state of the upper mold 7 from both sides. When the upper mold 7 descends, the optical monitoring module 19 monitors the distance between the two walls of the upper mold 7 through infrared. When the distance changes by a set amount, it indicates that the upper mold 7 is deformed, which means that the upper mold 7 needs to be replaced or corrected.

[0052] A bottom stability frame 20 is fixedly installed at the lower end of the annular guide seat 3.
