[0010] The rolling mill is configured to roll the steel strip into shape, the input end of the rolling mill is connected to the output end of the stamping mechanism, and the steel strip can pass through the leveling mechanism, the welding mechanism, the stamping mechanism and the rolling mill in sequence.

[0011] Preferably, a buffer zone is provided between the welding mechanism and the stamping mechanism, and when the speed of the steel strip at the output end of the welding mechanism is inconsistent with the speed of the input end of the stamping mechanism, the steel strip can bend and sag in the buffer zone.

[0014] Preferably, the buffer area is provided with a first monitoring mechanism, and the position of the first monitoring mechanism is lower than the output end of the welding mechanism and the input end of the stamping mechanism. When the steel strip contacts the first monitoring mechanism, the leveling mechanism and the welding mechanism stop operating.

[0015] Preferably, a second monitoring mechanism is further provided in the buffer area, and the second monitoring mechanism is located above the first monitoring mechanism. The steel strip is passed between the first monitoring mechanism and the second monitoring mechanism. When the steel strip contacts the second monitoring mechanism, the stamping mechanism and the rolling mill stop operating.

[0016] Preferably, it further comprises a discharge mechanism, the steel strip is wound on the discharge mechanism, the output end of the discharge mechanism is connected to the input end of the leveling mechanism, and the discharge mechanism can feed the steel strip into the input end of the leveling mechanism.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, it can be a mechanical connection or an electrical connection, it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above", "above" and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0042] like Figure 1 As shown, the present invention provides a welding-before-punching steel strip processing equipment, which is used to process a steel strip 100, and the welding-before-punching steel strip processing equipment includes a leveling mechanism 1, a welding mechanism 2, a punching mechanism 3 and a rolling mill 4. Among them, the leveling mechanism 1 is configured to level the bent steel strip 100; the welding mechanism 2 is configured to weld the tail of one steel strip 100 to the head of another steel strip 100, and the input end of the welding mechanism 2 is connected to the output end of the leveling mechanism 1; the punching mechanism 3 is configured to punch holes on the steel strip 100; the rolling mill 4 is configured to roll the steel strip 100 into shape, and the input end of the rolling mill 4 is connected to the output end of the punching mechanism 3, and the steel strip 100 can pass through the leveling mechanism 1, the welding mechanism 2, the punching mechanism 3 and the rolling mill 4 in sequence.

[0043] The leveling mechanism 1 and the welding mechanism 2 cooperate with each other so that the two leveled steel strips 100 can be connected end to end, thereby improving the utilization rate of the steel strips 100 and reducing waste. At the same time, the stamping mechanism 3 and the rolling mill 4 cooperate with each other to first punch holes on the steel strip 100 and then roll the steel strip 100 into shape. The leveling mechanism 1, the welding mechanism 2, the stamping mechanism 3 and the rolling mill 4 work together to ensure processing efficiency.

[0044] It can be understood that the leveling mechanism 1, the welding mechanism 2, the stamping mechanism 3 and the rolling mill 4 are all existing technologies disclosed in the art, and their working principles are not described in detail here.

[0045] Preferably, in this embodiment, the welding mechanism 2 adopts argon arc welding.

[0046] Specifically, a buffer zone is provided between the welding mechanism 2 and the punching mechanism 3. When the speed of the steel strip 100 at the output end of the welding mechanism 2 is inconsistent with the speed of the input end of the punching mechanism 3, the steel strip 100 can bend and sag in the buffer zone. The provision of the buffer zone can prevent the steel strip 100 from breaking or equipment damage when the speed of the steel strip 100 at the output end of the welding mechanism 2 is inconsistent with the speed of the input end of the punching mechanism 3, thereby improving safety.

[0047] Preferably, in this embodiment, the length of the buffer area is 3000 mm. In other embodiments, the length of the buffer area can also be adjusted according to the operation requirements, which is not specifically limited here.

[0048] Specifically, the welding-before-punching steel strip processing equipment further includes a feeding mechanism 5, which is arranged at one end of the buffer area close to the punching mechanism 3, and the feeding mechanism 5 can feed the steel strip 100 into the punching mechanism 3, and detect and adjust the length of the steel strip 100 fed into the punching mechanism 3. The setting of the feeding mechanism 5 enables the steel strip 100 to have a certain initial velocity when entering the punching mechanism 3, thereby preventing the transmission speed from being too slow due to excessive dead weight, and ensuring the working efficiency.

[0049] More specifically, the feeding mechanism 5 can feed in steps, and the step distance of the feeding mechanism 5 is consistent with the hole spacing of the punching mechanism 3. The above arrangement can improve the accuracy of the holes of the punching mechanism 3 and prevent the steel strip 100 from bending in the punching mechanism 3.

[0050] Preferably, in this embodiment, the step length of the feeding mechanism 5 is adjustable to adapt to different processing requirements, and has strong versatility.

[0051] Specifically, the buffer area is provided with a first monitoring mechanism 6, which is located lower than the output end of the welding mechanism 2 and the input end of the stamping mechanism 3. When the steel strip 100 contacts the first monitoring mechanism 6, the leveling mechanism 1 and the welding mechanism 2 stop working. The setting of the first monitoring mechanism 6 can prevent the length of the steel strip 100 retained in the buffer area from being too long, thereby causing the bent steel strips 100 to stack on each other or equipment damage, thereby ensuring the safety of the operation, the coordination between equipment and the operation efficiency.

[0052] More specifically, a second monitoring mechanism 7 is also provided in the buffer area, and the second monitoring mechanism 7 is located above the first monitoring mechanism 6. The steel strip 100 is arranged between the first monitoring mechanism 6 and the second monitoring mechanism 7. When the steel strip 100 contacts the second monitoring mechanism 7, the stamping mechanism 3 and the rolling mill 4 stop working. The provision of the second monitoring mechanism 7 can prevent the length of the steel strip 100 retained in the buffer area from being too small, thereby causing the steel strip 100 to be broken or the equipment to be damaged, thereby ensuring the safety of the operation, the coordination between the equipment and the operation efficiency.

[0053] Preferably, in this embodiment, both the first monitoring mechanism 6 and the second monitoring mechanism 7 are contact sensors in the prior art, and their specific structures are not described in detail herein.

[0054] Specifically, the welding-before-punching steel strip processing equipment further includes a feeding mechanism 8, on which the steel strip 100 is rolled up, and the output end of the feeding mechanism 8 is connected to the input end of the leveling mechanism 1, and the feeding mechanism 8 can feed the steel strip 100 into the input end of the leveling mechanism 1. The setting of the feeding mechanism 8 can unfold the steel coil into the steel strip 100, thereby improving the working efficiency.

[0055] More specifically, a receiving area is provided between the unloading mechanism 8 and the leveling mechanism 1, a third monitoring mechanism 9 is provided in the receiving area, the steel strip 100 can be bent in the receiving area, the third monitoring mechanism 9 is provided with a detection range, and when the distance between the steel strip 100 in the receiving area and the third monitoring mechanism 9 is less than the detection range, the unloading mechanism 8 stops operating. The provision of the third monitoring mechanism 9 can prevent the steel strip 100 from being retained too much in the receiving area, resulting in damage to the steel strip 100.

[0056] Preferably, in this embodiment, the third monitoring mechanism 9 is specifically a laser ranging sensor in the prior art, and its specific structure is not described in detail here.

[0057] Specifically, the input end of the welding mechanism 2 is provided with a fourth monitoring mechanism 21. When the tail of a steel strip 100 enters the input end of the welding mechanism 2, the fourth monitoring mechanism 21 can monitor whether the head of another steel strip 100 also enters the input end of the welding mechanism 2. If the head of another steel strip 100 does not enter the input end of the welding mechanism 2, the stamping mechanism 3 and the rolling mill 4 stop working. The above arrangement can prevent damage to the welding mechanism 2, the stamping mechanism 3 and the rolling mill 4, and improve the safety of the equipment.

[0058] Preferably, in this embodiment, the fourth monitoring mechanism 21 is a proximity switch commonly used in the art, and the specific structure is not described in detail here.

[0059] The present invention also discloses a processing method, which uses the above-mentioned welding-before-punching steel strip processing equipment and has all the beneficial effects of the above-mentioned welding-before-punching steel strip processing equipment, which will not be described in detail here. The processing method comprises the following steps:

[0060] S1 . The leveling mechanism 1 leveled the bent steel strip 100 .

[0061] In the above steps, the unwinding mechanism 8 unwinds the steel coil to form a steel strip 100 and passes it through the leveling mechanism 1. If the distance between the steel strip 100 in the accommodating area and the third monitoring mechanism 9 is less than the detection range, the unwinding mechanism 8 stops operating.

[0062] S2. The welding mechanism 2 welds the tail of one steel strip 100 to the head of another steel strip 100.

[0063] In the above steps, the steel strip 100 corrected by the leveling mechanism 1 passes through the welding mechanism 2. When the tail of one steel strip 100 enters the input end of the welding mechanism 2, the fourth monitoring mechanism 21 can monitor whether the head of another steel strip 100 also enters the input end of the welding mechanism 2. If the head of the other steel strip 100 does not enter the input end of the welding mechanism 2, the stamping mechanism 3 and the rolling mill 4 stop operating.

[0064] S3 , the punching mechanism 3 punches holes in the steel strip 100 .

[0065] In the above steps, the steel strip 100 passes through the buffer area and enters the input end of the feeding mechanism 5. If the steel strip 100 contacts the first monitoring mechanism 6, the leveling mechanism 1 and the welding mechanism 2 stop working; if the steel strip 100 contacts the second monitoring mechanism 7, the stamping mechanism 3 and the rolling mill 4 stop working.

[0066] S4. The rolling mill 4 rolls the steel strip 100 into shape.

[0067] In the above steps, different types of rolling mills 4 can be replaced according to processing requirements.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
