[0026] The present application will be further described in detail below in combination with the drawings and specific embodiments: Example 1

[0027] Reference Figures 1-7 ,

[0028] The single machine multi-station linkage type press comprises a press 1, the press 1 comprises a bearing table 11 for fixing a mold and a lower pressing plate 12 for fixing a mold punch, the lower pressing plate 12 is designed in parallel with the bearing table 11, and the lower pressing plate 11 can move up and down in parallel with the bearing table 11 when the press 1 is running.

[0029] The bearing table 11 is provided with a plurality of bottom molds 2, the bottom mold 2 is provided with a mold cavity for forming, a plurality of blow holes 21 are uniformly arranged on the bottom surface of the mold cavity, the blow holes 21 can upwardly spray high-pressure airflow, thereby blowing the particulate matter or dust in the mold cavity upwardly out of the mold cavity, and a ring groove 22 is arranged on the peripheral wall at the middle position of the mold cavity, the ring groove 22 is communicated with the dust suction port of the dust suction device, thereby forming a negative pressure suction force around the ring groove 22, sucking the dust or particulate matter around into the dust suction device, thereby reducing the dust in the mold cavity, and the ring groove 22 cooperates with the blow holes 21 at the bottom to remove most of the dust and particulate matter.

[0030] The annular groove 22 is arranged in the circumferential direction of the mold cavity, so that the particles or dust at the middle position of the mold cavity cannot be adsorbed, and then blown out of the upper surface of the bottom die 2 and dispersed in the surrounding air, and finally fall back into the mold cavity or fly outwards. The dust and particles falling back to the bottom of the mold cavity will accumulate during each stamping process, and then the dust and particles blown out each time will increase in turn.

[0031] The bottom die 2 is provided with a detection member 3 for detecting dust and particles. The detection member 3 can be a laser dust detector, which can detect the dust in the airflow flowing through the detection member 3 when the high-pressure airflow is injected upward through the blowing hole 21, and identify the concentration of dust or particles above the bottom die 2.

[0032] When the content of dust or particles in the mold cavity is high, the more dust or particles dispersed above the bottom die 2 by the airflow, the larger the value measured by the detection member 3. Therefore, the dust detection is performed by the detection member 3, and when the set value is reached, the cleaning device 4 arranged on the press can be controlled to clean the mold cavity.

[0033] The cleaning device 4 includes a cleaning member 41, a moving device 42, a feeding member 43, a collecting member 44, a sealing member 45, an expansion device 46, and a main body frame 47. The moving device 42 includes a track group 421 and a moving block 422. The track group 421 is arranged on the bearing table 11, and the moving block 422 is slidingly arranged on the track group 421. A servo motor is arranged on the moving block 422, so that the moving block 422 can move accurately forward and backward on the track group 421. The track group 421 and the moving block 422 belong to large bearing type moving assemblies, which can bear a large load.

[0034] The main body frame 47 is elastically connected with the moving block 422 through an elastic guide sliding member. One end of the elastic guide sliding member is arranged at the bottom of the main body frame 47, and the other end is connected with the upper end of the moving block 422. The elastic guide sliding member can be elastically contracted under pressure, so that the main body frame 47 can be guided to move downward as a whole under downward pressure, and can return to the initial state upward when the pressure disappears.

[0035] The main frame 47 is provided with a punching hole 471, a channel cavity 472, a material cavity 473 and a material receiving cavity 474. The material cavity 473 and the material receiving cavity 474 are respectively located at the left and right ends of the main frame 47 and are communicated with each other through the channel cavity 472. The punching hole 471 is vertically arranged and perpendicular to the channel cavity 472. The feeding member 43 and the material receiving member 44 are both roller shafts. Two feeding members 43 are arranged in the material cavity 473 and rotate in a damping manner, and the material receiving member 44 is arranged in the material receiving cavity 474. The material receiving member 44 is provided with a power member which can rotate under the control of an electric control unit. The cleaning member 41 is a single-sided adhesive elastic film which can be elastically deformed, stretched, blown and so on when subjected to pressure. Two cleaning members 41 are arranged, and one end of each of the two cleaning members 41 is wound around a feeding member 43, and the other end is arranged on the material receiving member 44. The middle connecting part passes through the channel cavity 472. The channel cavity 472 is parallel to the lower pressing plate 12. When the punching head descends, the lower end of the punching head 121 presses the cleaning member 41 and drives the cleaning member 41 into the mold cavity.

[0036] The sealing member 45 includes a ring-shaped pressing ring 451 and four guide contact rods 452 arranged on the four corners of the lower end surface of the ring-shaped pressing ring 451. The lower end surface of the channel cavity 472 is provided with guide holes. The sealing member 45 is guided and slidably arranged in the guide holes through the four guide contact rods 452, so that the ring-shaped pressing ring 451 is slidably arranged in the channel cavity 472. An elastic sealing ring 4511 is arranged on the upper surface of the ring-shaped pressing ring 451. An elastic sealing ring 4511 is also arranged on the upper end wall of the channel cavity 472 corresponding to the ring-shaped pressing ring 451. The upper and lower elastic sealing rings 4511 are aligned. Four electromagnets are uniformly distributed in the upper end wall of the channel cavity 472 above the ring-shaped pressing ring 451. The electromagnets can attract the ring-shaped pressing ring 451 upward. The two cleaning members 41 pass between the two elastic sealing rings 4511. When the electromagnets are electrified, the two elastic sealing rings 4511 seal and close the area of the two cleaning members 41 in the elastic sealing ring 4511.

[0037] Wherein since two cleaning pieces 41 have sticky material on the outer surface, and the surface pressed by the elastic sealing ring 4511 also has sticky material, thus after the electromagnet is powered off, two cleaning pieces 41 are still adhered to the upper and lower elastic sealing rings 4511 respectively, therefore a plurality of small holes are arranged on the plane of the elastic sealing ring 4511, and oily material is stored in the elastic sealing ring 4511, when two elastic sealing rings 4511 are in contact and deformed to seal and close the area of two cleaning pieces 41 in the elastic sealing ring 4511, the stored oily material is squeezed out from the plurality of small holes and flows on the surface of the elastic sealing ring 4511, so that the position of the elastic sealing ring 4511 in contact with the cleaning piece 41 is not adhered.

[0038] The expansion device 46 includes an inflation nozzle 461 and a docking head 462, the inflation nozzle 461 is in a C-shaped structure, a sliding groove 4521 is arranged on the guide contact rod 452, the lower end of the C-shaped inflation nozzle 461 is slidingly arranged in the sliding groove 4521 and connected with one end of a flexible pipe arranged in the guide contact rod 452, a docking hole is arranged at the lower end of the guide contact rod 452, and the other end of the flexible pipe is in communication with the docking hole, and the docking head 462 is arranged on the upper end surface of the bottom die 2.

[0039] The lower pressing plate 12 is further provided with a top contact block 122, after the punch head 121 is lowered in place, the top contact block 122 is in contact with the main frame 47, at this time the docking hole at the lower end of the guide contact rod 452 is inserted into the docking head 462 on the bottom die 2, thereby realizing the supply of compressed air, so that the inflation nozzle 461 can spray compressed air.

[0040] The upper end of the C-shaped inflation nozzle 461 is flat, and the two cleaning pieces 41 are located between the two cleaning pieces 41 from the side of the two cleaning pieces 41, that is, one of the two cleaning pieces 41 passes above the inflation nozzle 461, and the other passes below the inflation nozzle 461, wherein when the lower pressing plate 12 starts to descend, the electromagnet is powered on, thereby the annular pressing ring 451 is adsorbed upward, the two elastic sealing rings 4511 seal and close the area of the two cleaning pieces 41 in the elastic sealing ring 4511, and at this time the inflation nozzle 461 is also located between the two, at this time the lower pressing plate 12 continues to descend, and the punch head 121 is in contact with the cleaning piece 41, at this time the cleaning piece 41 around the contact position is pressed tightly, thereby in the process of continuous descent of the punch head 121, the cleaning piece 41 is elastically deformed and enters the mold cavity together with the punch head 121.

[0041] After the lower plate 12 is lowered into position, the abutting hole at the lower end of the guide contact rod 452 is inserted into the abutting head 462 on the bottom die 2, and then the supply of compressed air is realized, so that the inflation nozzle 461 can spray compressed air, and then the two pieces of cleaning piece 41 are inflated under the action of the intermediate compressed air, and then the upper cleaning piece 41 is tightly attached to the stamping head 121, and the lower cleaning piece 41 is tightly attached to the die cavity wall, and the sticky material on the surface of the cleaning piece 41 adheres the dust or particles on the stamping head 121 and the die cavity.

[0042] The working principle or method of use is as follows:

[0043] The lower plate 12 moves downward, and the stamping head of the plurality of stations is driven to perform the stamping forming work.

[0044] After each forming is completed, the blowing hole 21 at the bottom of the die cavity can spray high-pressure airflow upward, and the annular groove 22 can adsorb the high-speed airflow under negative pressure to hit the dust, and part of the dust cannot be removed and will fall back into the die cavity. After the stamping operation is performed for many times, the dust and particles on the bottom surface of the die cavity are accumulated, and then the dust and particles blown out each time will increase in turn. The more the dust or particle content dispersed by the airflow above the bottom die 2, the more the dust detection is performed by the detection piece 3, and when the set value is reached, the cleaning device 4 arranged on the press can be controlled to clean the die cavity.

[0045] The moving block 422 is controlled to move, and the main body frame 47 is sent to below the stamping head 121. The lower plate 12 starts to descend, the electromagnet is energized, and then the annular pressing ring 451 is adsorbed upward. The two elastic sealing rings 4511 seal and close the area where the two cleaning pieces 41 are located in the elastic sealing ring 4511, and at this time the inflation nozzle 461 is also located between the two. The lower plate 12 continues to descend, and the stamping head 121 contacts the cleaning piece 41. At this time, the cleaning piece 41 around the contact position is pressed tightly, and then the stamping head 121 drives the cleaning piece 41 to deform elastically in the subsequent continuous descending process, and enters the die cavity together with the stamping head 121.

[0046] After the lower plate 12 is lowered into position, the abutting hole at the lower end of the guide contact rod 452 is inserted into the abutting head 462 on the bottom die 2, and then the supply of compressed air is realized, so that the inflation nozzle 461 can spray compressed air, and then the two pieces of cleaning piece 41 are inflated under the action of the intermediate compressed air, and then the upper cleaning piece 41 is tightly attached to the stamping head 121, and the lower cleaning piece 41 is tightly attached to the die cavity wall, and the sticky material on the surface of the cleaning piece 41 adheres the dust or particles on the stamping head 121 and the die cavity.

[0047] After the lower plate 12 is pressed for a period of time, it starts to recover upwardly, in the process of recovery, the docking hole is disconnected from the docking head 462, and then the compressed air stops being supplied, the two layers of cleaning pieces 41 recover to the close state under the action of the elastic force, the air filled in the inside is discharged outwardly through the air filling nozzle 461, the punch head 121 recovers upwardly, and the cleaning piece 41 recovers to the initial flat state.

[0048] The surface finish of the punch head 121 and the die cavity is high, so the cleaning piece 41 cannot adhere to the surfaces of the punch head 121 and the die cavity, and can be separated by the elastic recovery force, and the dust or particles adhere to the surface of the cleaning piece 41.

[0049] When the lower plate 12 recovers to the initial height, the electromagnet is powered off, the two cleaning pieces 41 are separated, the material collecting piece 44 starts to rotate, and the used part is wound on the material collecting piece 44, while the two feeding pieces 43 are pulled to rotate and feed the unused part to below the punch head 121, so as to prepare for the next cleaning, the moving block 422 moves backward to drive the main body frame 47 to move away from below the punch head 121, and then a complete cleaning work is completed. Embodiment 2

[0050] Referring to Figures 1-7 The difference between the embodiment and the embodiment 1 is that the operation time of the material collecting piece 44 is different, and the rest is the same.

[0051] In the embodiment, after the cleaning piece 41 completes the cleaning of the die cavity, the equipment is reset, the material collecting piece 44 does not rotate, that is, the used part continues to be located in the punch hole, and then when the air flow is injected upwardly in the blowing hole 21, part of the dust and particles blown upwardly will impact on the position of the used cleaning piece 41, and then continuously adhere to the dust and particles.

[0052] When the detection piece 3 detects that the dust content increases, the material collecting piece 44 starts to work, and the used part is wound on the material collecting piece 44, and the unused part enters the punch hole, so that the cleaning piece for cleaning the die cavity and the punch head is unused, and the adhesion of the surface of the cleaning piece 31 is ensured.

[0053] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
