DETAILED DESCRIPTION
[0029] The following will be described in detail in combination with the drawings Figures 1-3 The present application will be further described in detail.
[0030] The embodiment of the present application discloses a counter-positioning die cutting device for metal processing. Referring to Figure 1The metal processing opposite positioning die cutting device comprises a workbench 1, a longitudinal positioning mechanism 2, a transverse positioning mechanism 3 and a die cutting mechanism 4 arranged on the workbench 1. The longitudinal positioning mechanism 2 is used for positioning the metal plate longitudinally, the transverse positioning mechanism 3 is used for positioning the metal plate transversely, and the die cutting mechanism 4 is used for die cutting the metal plate placed on the workbench 1.
[0031] With reference to Figures 1-2 The longitudinal positioning mechanism 2 comprises a positioning baffle 21 and a locking assembly. A first sliding groove 11 is longitudinally arranged on the upper surface of the workbench 1, and the bottom of the positioning baffle 21 is slidably arranged in the first sliding groove 11. The locking assembly comprises a screw rod 22 and a rotary driving member 23. The screw rod 22 is rotationally connected to the first sliding groove 11 along the sliding direction of the positioning baffle 21, and the screw rod 22 is arranged through the positioning baffle 21 and is threadedly connected with the positioning baffle 21. The rotary driving member 23 is a hand wheel, which is coaxially connected to the screw rod 22.
[0032] The hand wheel is rotated to drive the screw rod 22 to rotate. The threaded connection between the screw rod 22 and the positioning baffle 21 enables the positioning baffle 21 to slide along the first sliding groove 11, so as to adjust the position of the positioning baffle 21. When the metal plate is placed, one end of the metal plate is abutted against the positioning baffle 21, so as to position the metal plate longitudinally.
[0033] With reference to Figure 3 The transverse positioning mechanism 3 comprises a first sliding block 31, a second sliding block 32 and a driving assembly. The first sliding block 31 and the second sliding block 32 are slidably connected to the workbench 1, and the driving assembly is arranged on the workbench 1. The driving assembly is used for driving the first sliding block 31 and the second sliding block 32 to move close to or away from each other. The sliding directions of the first sliding block 31 and the second sliding block 32 are perpendicular to the sliding direction of the positioning baffle 21. In use, after one end of the metal plate is abutted against the positioning baffle 21, the first sliding block 31 and the second sliding block 32 are driven to move close to each other by the driving assembly until the first sliding block 31 and the second sliding block 32 are abutted against the two sides of the metal plate, so as to clamp and fix the metal plate, thereby achieving accurate positioning of the metal workpiece.
[0034] For example, the driving assembly comprises a first rack 33, a second rack 34, a gear 35 and a power component. The gear 35 is rotationally connected below the workbench 1. The first rack 33 is fixedly welded to the first sliding block 31. The extension direction of the first rack 33 is the same as the sliding direction of the first sliding block 31. The first rack 33 is meshed with the lower teeth of the gear 35. The second rack 34 is fixedly welded to the second sliding block 32. The extension direction of the second rack 34 is the same as the sliding direction of the second sliding block 32. The second rack 34 is meshed with the upper teeth of the gear 35. The power component is arranged on the workbench 1, and is used for driving the gear 35 to rotate.
[0035] When the power component drives the gear 35 to rotate, the first rack 33 and the second rack 34 can be simultaneously moved in opposite directions, thereby driving the first slider 31 and the second slider 32 to approach or move away from each other, the structure is relatively simple, the manufacturing cost is reduced, and the stability of the movement of the first slider 31 and the second slider 32 is improved.
[0036] For example, the power component includes a rotating motor 36, a worm gear 37 and a worm 38, the worm gear 37 is coaxially connected with the gear 35, the rotating motor 36 is fixedly installed on the workbench 1, the rotating shaft of the rotating motor 36 is coaxially connected with the worm 38, and the worm 38 is engaged with the worm gear 37. When it is necessary to adjust the positions of the first slider 31 and the second slider 32, the rotating motor 36 is started and drives the worm 38 to rotate, the worm 38 is engaged with the worm gear 37, so that the worm gear 37 is driven to rotate, and since the worm gear 37 is coaxially connected with the gear 35, the gear 35 is also driven to rotate. By utilizing the self-locking characteristics of the worm gear 37 and the worm 38, when the rotating motor 36 stops rotating, the worm gear 37 can be locked, thereby the positions of the first slider 31 and the second slider 32 are locked, the positioning accuracy and stability are improved.
[0037] Further, in order to reduce the damage probability of the first slider 31 and the second slider 32 to the plate when clamping and fixing the plate, the side of the first slider 31 and the second slider 32 approaching each other is provided with an elastic element 39, and the elastic element 39 specifically adopts a spring in the application. The two elastic elements 39 are connected with a buffer plate 310 at the end approaching each other. The buffer plate 310 replaces the first slider 31 and the second slider 32 to contact the plate, so that a buffer can be provided when clamping the plate, and the damage to the plate is reduced. In addition, in order to increase the friction between the buffer plate 310 and the plate to prevent the plate from sliding, the buffer plate 310 is provided with anti-skid lines.
[0038] For example, the die-cutting mechanism 4 includes a support 41, a die-cutting plate 42 and a linear driving element 43, the support 41 is welded and fixed on the workbench 1, the support 41 is in the shape of an inverted U as a whole, the linear driving element 43 is fixedly installed on the support 41 in the vertical direction, the linear driving element 43 adopts a telescopic cylinder, and the die-cutting plate 42 is fixedly connected to the output end of the linear driving element 43. The up-down reciprocating movement of the die-cutting plate 42 is realized by driving the telescopic cylinder to elongate or retract, thereby realizing the die-cutting operation on the plate.
[0039] Further, the limit rod 44 is welded and fixed on the top of the die-cutting plate 42 in the vertical direction, the limit rod 44 is arranged through the support 41, the limit rod 44 is provided with a bump block 45, the support 41 is provided with a travel switch 46, and the bump block 45 is used to abut against the contact of the travel switch 46. In this way, when the die-cutting plate 42 is lowered to the set position, the bump block 45 will trigger the travel switch 46, a stop signal is sent out, and the safety and reliability of the die-cutting process are ensured.
[0040] The implementation principle of the counter-positioning die-cutting device for metal processing is as follows: in use, the wire rotates the hand wheel to drive the screw 22 to rotate, so as to adjust the positioning baffle 21 to a suitable position. Then the metal plate is directly placed on the workbench 1, and one end of the plate is abutted against the positioning baffle 21, at this time the positioning baffle 21 precisely positions the plate vertically. Then the rotating motor 36 is started to drive the worm 38 to rotate, drive the worm wheel 37 to rotate, drive the gear 35 to rotate, drive the first rack 33 and the second rack 34 to move in opposite directions at the same time, thereby drive the first slider 31 and the second slider 32 to approach each other, until the buffer plate 310 abuts against the plate to form clamping and fixing of the plate, realizing precise positioning of the plate horizontally. Then the linear drive 43 is started to drive the die-cutting plate 42 to move downward, until the die-cutting plate 42 is pressed against the plate to realize die-cutting work of the plate. The cooperation of the longitudinal positioning mechanism 2 and the transverse positioning mechanism 3 in the application realizes precise and stable positioning of the plate, and improves the problem that the direct placement of the metal plate requires higher experience of workers, there is human error, and the processing quality is affected.
[0041] The above are optional embodiments of the application, and do not limit the protection scope of the application, therefore: equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
