[0014] Preferably: the sliding assembly includes a guide block installed on one side of the vertical plate, a long rod is slidably matched with one side of the guide block, one end of the two slide cylinders are rotationally matched with one side of the long rod, and one end of the long rod is matched with the waste box, a protrusion is installed on one side of the long rod, and a protrusion rod slidably matched with the long rod is installed on one side of the vertical plate, and a plurality of second springs are installed between the protrusion and the protrusion rod.

[0016] Preferably: a processing method, comprising the sheet metal machining device:

[0017] Step 1: Lay the sheet metal steel plate blank flat and squeeze the first push plate to rotate the first push plate, and continue to push the sheet metal steel plate blank. At this time, one side of the sheet metal steel plate blank squeezes the fixed hemisphere, and the fixed hemisphere slides upward, and the first spring is compressed. When the sheet metal steel plate blank is completely placed on the upper side of the cutting machine, the four fixed hemispheres complete the fixation of the sheet metal steel plate blank, and then the sheet metal steel plate blank can be cut;

[0018] Step 2: After the sheet metal steel plate blank is cut, the two first motors are started. The first motor rotates the threaded rod through the first gear and the second gear, and the threaded rod causes the push block to slide toward the waste box. Under the blocking action of the L-shaped plate, the L-shaped plate pushes the sliding plate to slide along the sliding groove. The sheet metal after cutting will fall onto the upper side of the protection plate under the influence of gravity. When the long rod touches the waste box, the long rod stops moving, and the sliding plate and the vertical plate continue to move to change the relative position of the long rod and the sliding plate. The second spring is compressed by force, so that the slide cylinder and the limit block rotate, driving the slide rod to rotate and partially slide out of the slide cylinder, the first spring recovers, the fixed hemisphere no longer squeezes the steel plate blank waste, and at the same time the limit block rotates the third gear, and the third gear drives the L-shaped plate to slide into the blocking groove, thereby releasing the blocking of the push block.

[0019] Step 3: The push block continues to slide along the limit groove, and the first push plate between the two push blocks will squeeze and push the steel plate blank waste to continue to slide along the sliding plate under the obstruction of the baffle plate. The first push plate will push the steel plate blank waste through the waste opening into the waste box, completing the collection of the steel plate blank waste;

[0020] Step 4: Start the second motor, and the second motor makes the fan-shaped wheel rotate along the rotating wheel. Due to the change in the distance between the rotation center of the fan-shaped wheel and the center of the rotating wheel, the angle between the U-shaped frame and the protection plate and the bottom of the collecting trough gradually decreases until it is flush with the bottom of the collecting trough. At the same time, the push rod on one side of the fan-shaped wheel will squeeze the second push plate, so that the second push plate slides along the limit rod and the guide groove and squeezes the sheet metal molded part, and pushes the sheet metal molded part into the collection box to complete the collection of the sheet metal molded parts. Then, the first motor is rotated in the opposite direction to make the push block and the sliding plate slide to the original position to cut the next sheet metal steel plate blank.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The sliding plate is moved by the first motor and the pushing mechanism, and the separation component is cooperated to complete the collection and protection of the sheet metal molded parts. Then the fixing mechanism and the fixing component release the fixing effect, so that the pushing mechanism pushes the steel plate blank waste into the waste box, which can automatically complete the collection of sheet metal molded parts and steel plate blank waste, facilitate the next step of processing of the sheet metal molded parts, save manpower, and improve work efficiency. At the same time, the fixing mechanism ensures the stability of the sheet metal steel plate blank during cutting, and avoids the movement of the sheet metal steel plate blank during the cutting process, thereby affecting the cutting quality of the sheet metal molded parts.

[0034] The sliding plate 6 is moved by the first motor 17 and the pushing mechanism, and the separation component is cooperated to complete the collection and protection of the sheet metal molded parts.

At the same time, the fixing mechanism ensures the stability of the sheet metal steel plate blank during cutting, and avoids the movement of the sheet metal steel plate blank during the cutting process, thereby affecting the cutting quality of the sheet metal molded parts.

[0035] Embodiment 2

[0036] See also Figure 1 The cutting mechanism in the first embodiment includes a cutting frame 3 that is slidably matched with the two movable grooves 2, and a laser cutting machine 4 is slidably matched with one side of the cutting frame 3. This is an existing laser cutting processing technology and will not be described in detail here;

[0037] As Figure 4As shown, the separation component includes a rotating wheel 31 rotatably engaged in the collection chamber 41, a U-shaped frame 32 rotatably engaged in the collection chamber 41, a protection plate 33 is installed at one end of the U-shaped frame 32, two limiting rods 34 are installed on one side of the protection plate 33, a guide groove 35 is opened on the upper side of the protection plate 33, a second push plate 37 slidably engaged with the limiting rod 34 is slidably engaged in the guide groove 35, two connecting rods 36 are installed between the U-shaped frame 32 and the protection plate 33, a second motor 38 is installed on one side of the connecting rod 36, a fan-shaped wheel 39 rotatably engaged with the rotating wheel 31 is installed at the output end of the second motor 38, a push rod 40 rotatably engaged with the second push plate 37 is rotatably engaged in the middle of the fan-shaped surface of the fan-shaped wheel 39, and the fan-shaped wheel 39 is driven by the second motor 38. 39 rotates, thereby changing the distance between the rotation center of the sector wheel 39 and the center of the rotating wheel 31, thereby changing the angle between the U-shaped frame 32 and the protection plate 33 and the bottom of the collecting trough 30. When the sheet metal molded parts fall onto the protection plate 33 after processing, the protection plate 33 cushions the sheet metal molded parts to avoid the collision caused by the falling of the sheet metal molded parts, which may affect the quality of the sheet metal molded parts. At the same time, when the sector wheel 39 rotates, the angle of the push rod 40 is changed, so that the push rod 40 pushes the second push plate 37, and the second push plate 37 pushes the sheet metal molded parts into the collecting box 42, which can automatically complete the collection of the sheet metal molded parts, facilitate the next step of processing of the sheet metal molded parts, save manpower, and improve work efficiency.

The sheet metal steel plate blank can be fixed by the fixed hemisphere 10, and the sheet metal steel plate blank can be prevented from moving during the cutting process, thereby affecting the cutting quality of the sheet metal formed part;

[0040] As Figure 3As shown, the sliding assembly includes a guide block 14 installed on one side of the vertical plate 7, and a long rod 13 is slidably matched with one side of the guide block 14. One end of the two slide cylinders 12 are rotatably matched with one side of the long rod 13, and one end of the long rod 13 is matched with the waste box 43. A protrusion 26 is installed on one side of the long rod 13, and a protrusion 27 slidably matched with the long rod 13 is installed on one side of the vertical plate 7. A plurality of second springs 28 are installed between the protrusion 26 and the protrusion 27. Through the mutual cooperation between the long rod 13 and the waste box 43, after the long rod 13 contacts the waste box 43, the relative position of the long rod 13 and the sliding plate 6 changes, so that the second spring 28 is compressed, and at the same time, the slide cylinder 12, the slide rod 9 and the limit block 8 are driven to rotate, thereby releasing the fixation of the fixed hemisphere 10 on the steel plate blank waste, facilitating the collection of the steel plate blank waste, saving manpower and improving work efficiency.

[0041] Embodiment 4

[0042] See also Figures 2 to 7 The pushing mechanism in the first embodiment includes a first gear 18 installed at the output end of the first motor 17, a second gear 19 meshing with the first gear 18 is rotatably matched on one side of the cutting machine 1, a threaded rod 20 is installed on one side of the second gear 19, and a push block 16 slidably matched with the limiting groove 15 is threadedly matched on the circumferential side of the threaded rod 20, and a first push plate 23 is rotatably matched between the two push blocks 16, and the fixing component includes a cavity 21 opened in the vertical plate 7, a blocking groove 22 opened in the sliding plate 6 and connected to the limiting groove 15, and the cavity 21 is connected to the blocking groove 22, and the limiting groove 15 is connected to the cavity 21. A third gear 24 located inside the cavity 21 is installed on one side of the positioning block 8, and an L-shaped plate 25 that cooperates with the push block 16 is slidably matched inside the cavity 21 and the blocking groove 22. A rack that meshes with the third gear 24 is installed on one side of the L-shaped plate 25. A baffle 29 that cooperates with the first push plate 23 is installed on one side of the push block 16, and the baffle 29 is located on the side near the waste box 43. The first push plate 23 is consistent in height with the waste opening 44. The threaded rod 20 is rotatably matched with the cutting machine 1, and the cavity 21 and the blocking groove 22 are matched with the limiting block 8 at one end away from the waste box 43;

[0043] By starting the first motor 17 to rotate the first gear 18 and the second gear 19, the threaded rod 20 is rotated, and the threaded rod 20 causes the push block 16 to slide toward the waste box 43. Under the blocking effect of the L-shaped plate 25, the L-shaped plate 25 pushes the sliding plate 6 to slide along the sliding groove 5, thereby pushing the sliding plate 6 and the vertical plate 7 to slide. After the support of the cutting machine 1 on the central part of the sheet metal steel plate blank is lost, the sheet metal molded parts fall from the cut sheet metal steel plate blank, which is convenient for collecting the sheet metal molded parts. At the same time, the remaining steel plate blank waste can be collected, which is convenient for the next step of processing the sheet metal molded parts, saving manpower and improving work efficiency.

[0044] Embodiment 5

[0045] A processing method of a sheet metal machining device comprises the following steps:

[0046] Step 1: Lay the sheet metal steel plate blank flat and squeeze the first push plate 23 to rotate the first push plate 23, and continue to push the sheet metal steel plate blank. At this time, one side of the sheet metal steel plate blank squeezes the fixed hemisphere 10, and the fixed hemisphere 10 slides upward, and the first spring 11 is compressed by force. When the sheet metal steel plate blank is completely placed on the upper side of the cutting machine 1, the four fixed hemispheres 10 complete the fixation of the sheet metal steel plate blank, and then the sheet metal steel plate blank can be cut;

[0047] Step 2: After the sheet metal blank is cut, the two first motors 17 are started. The first motor 17 rotates the threaded rod 20 through the first gear 18 and the second gear 19. The threaded rod 20 causes the push block 16 to slide toward the direction close to the waste bin 43. Under the blocking effect of the L-shaped plate 25, the L-shaped plate 25 pushes the sliding plate 6 to slide along the sliding groove 5. The sheet metal after cutting will fall to the upper side of the protection plate 33 under the influence of gravity. When the long rod 13 touches the waste bin 43, the long rod 13 stops moving, and the sliding plate 6 and the vertical plate 7 continue to move to change the relative position of the long rod 13 and the sliding plate 6. The second spring 28 is compressed, so that the slide 12 and the limit block 8 rotate, driving the slide bar 9 to rotate and partially slide out of the slide 12, the first spring 11 recovers, the fixed hemisphere 10 no longer squeezes the steel plate blank waste, and at the same time the limit block 8 rotates the third gear 24, the third gear 24 drives the L-shaped plate 25 to slide into the blocking groove 22, and the blocking of the push block 16 is released. It should be noted that the elastic force of the second spring 28 cannot push the sliding plate 6 to slide along the sliding groove 5. Therefore, when the push block 16 no longer pushes the sliding plate 6, the sliding plate 6 is in a fixed state under the elastic force of the second spring 28;

[0048] Step 3: The push block 16 continues to slide along the limiting groove 15, and the first push plate 23 between the two push blocks 16 squeezes and pushes the steel plate blank waste to continue to slide along the sliding plate 6 under the obstruction of the baffle plate 29, and the first push plate 23 pushes the steel plate blank waste through the waste opening 44 into the waste box 43, completing the collection of the steel plate blank waste;

[0049] Step 4: Start the second motor 38, and the second motor 38 makes the fan wheel 39 rotate along the rotating wheel 31. Due to the change in the distance between the rotation center of the fan wheel 39 and the center of the rotating wheel 31, the angle between the U-shaped frame 32 and the protection plate 33 and the bottom of the collecting tank 30 gradually decreases, until it is flush with the bottom of the collecting tank 30. At the same time, the push rod 40 on one side of the fan wheel 39 will squeeze the second push plate 37, so that the second push plate 37 slides along the limit rod 34 and the guide groove 35 and squeezes the sheet metal molded part, and pushes the sheet metal molded part into the collection box 42 to complete the collection of the sheet metal molded parts. Then, the first motor 17 rotates in the opposite direction to make the push block 16 and the sliding plate 6 slide to the original position so that the next sheet metal steel plate blank can be cut.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

At this time, one side of the sheet metal steel plate blank squeezes the fixed hemisphere (10), and the fixed hemisphere (10) slides upward, and the first spring (11) is compressed. When the sheet metal steel plate blank is completely placed on the upper side of the cutting machine (1), the four fixed hemispheres (10) complete the fixation of the sheet metal steel plate blank, and then the sheet metal steel plate blank can be cut; Step 2: After the sheet metal blank is cut, the two first motors (17) are started. The first motors (17) rotate the threaded rod (20) through the first gear (18) and the second gear (19). The threaded rod (20) causes the push block (16) to slide toward the waste bin (43). Under the blocking effect of the L-shaped plate (25), the L-shaped plate (25) pushes the sliding plate (6) to slide along the sliding groove (5). After the sheet metal is cut, it falls onto the upper side of the protection plate (33) under the influence of gravity. When the long rod (13) touches the waste bin (43), the long rod (13) 3) the movement stops, the sliding plate (6) and the vertical plate (7) continue to move so that the relative position of the long rod (13) and the sliding plate (6) changes, the second spring (28) is compressed, so that the slide cylinder (12) and the stop block (8) rotate, driving the slide rod (9) to rotate and partially slide out of the slide cylinder (12), the first spring (11) recovers, the fixed hemisphere (10) no longer squeezes the steel plate blank waste, and at the same time the stop block (8) causes the third gear (24) to rotate, and the third gear (24) drives the L-shaped plate (25) to slide into the blocking groove (22), thereby releasing the blocking of the push block (16); Step 3: The push block (16) continues to slide along the limiting groove (15), and the first push plate (23) between the two push blocks (16) squeezes and pushes the steel plate blank waste to continue to slide along the sliding plate (6) under the obstruction of the baffle plate (29). The first push plate (23) pushes the steel plate blank waste through the waste opening (44) into the waste box (43), thereby completing the collection of the steel plate blank waste; Step 4: Start the second motor (38), the second motor (38) causes the fan-shaped wheel (39) to rotate along the rotating wheel (31). As the distance between the rotation center of the fan-shaped wheel (39) and the center of the rotating wheel (31) changes, the angle between the U-shaped frame (32) and the protection plate (33) and the bottom of the collecting tank (30) gradually decreases until it is flush with the bottom of the collecting tank (30). At the same time, the push rod (40) on one side of the fan-shaped wheel (39) squeezes the second push plate (37), causing the second push plate (37) to slide along the limit rod (34) and the guide groove (35) and squeeze the sheet metal molded part, and push the sheet metal molded part into the collection box (42), completing the collection of the sheet metal molded parts, and then the first motor (17) is rotated in the opposite direction to slide the push block (16) and the sliding plate (6) to the original position so that the next sheet metal steel plate blank can be cut.
