Description

Technical Field

[0001] The invention belongs to the technical field of steel strip processing, and more specifically relates to a steel strip and processing equipment and method thereof. Background Art

[0002] During the processing of cold-rolled steel strips, burrs often exist on both sides of the steel strips because the entire steel plate needs to be pressed and cut into steel strips, which need to be polished and removed. When the edge of the steel strip needs to be trimmed into a specific shape, it is necessary to trim the edge of the steel strip again after the burrs are removed so that the edge of the steel strip can present a corresponding shape, such as a semicircular shape to avoid workers cutting their hands during movement, a straight shape for easy stacking, and a positive and negative V-shape for easy splicing. The existing burr removal mechanism mainly removes burrs through a scraper fixed on the slide rail, and it is impossible to trim the edge of the steel strip at the same time. When the shape of the steel strip edge needs to be trimmed, the edge of the steel strip needs to be processed twice, which is a complicated process. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a steel strip and a processing device and method thereof, the beneficial effect of the present invention is that the present invention can remove burrs on the edge of the steel strip and trim the edge of the steel strip into different shapes according to requirements.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A steel strip processing equipment comprises a pushing frame, which is slidably connected to two symmetrically arranged cutting parts, and the two cutting parts can be fixed to the pushing frame by bolts. The two cutting parts each comprise a trimming blade and a limit block, and the limit block is slidably connected to the pushing frame. Two symmetrically arranged pushing parts are installed between the trimming blade and the limit block. The pushing part comprises an inner slide plate, which is slidably connected to the pushing frame, an outer clamping plate is fixedly connected to the outer side of the inner slide plate, a fixing strip is fixedly connected between the inner slide plate and the outer clamping plate, the lower end of the fixing strip is rotatably connected to one side of the trimming blade, and the other side of the trimming blade is rotatably connected to one end of a movable strip, the other end of the movable strip passes through between the inner slide plate and the outer clamping plate and is slidably connected to the limit block, and a locking screw is threadedly connected to the outer clamping plate.

[0006] The trimming blade is provided with four connection ports, and the fixed bar and the movable bar in the pushing part can be rotatably connected inside the corresponding connection ports.

[0007] The trimming blades are arranged in groups of two in a plurality of groups, and the curvatures of the trimming blades in the plurality of groups are different.

[0008] A steel strip processing method comprises the following steps:

[0009] S1: Pressing and cutting the obtained steel strip sheet to obtain a semi-finished steel strip;

[0010] S2: According to the requirements of steel belt edge trimming, install the appropriate trimming blade on the lower side of the pusher;

[0011] S3: The processing equipment is clamped on one side of the semi-finished steel strip, so that the edge of the trimming blade is clamped on the edge of the semi-finished steel strip;

[0012] S4: Push the processing equipment so that the trimming blade can move forward along the edge of the steel strip, remove the burrs on the edge of the steel strip and trim the edge of the steel strip at the same time;

[0025] like Figure 1-4 As shown:

[0026] A steel strip processing device includes a push frame 000, on which two symmetrically arranged cutting parts 100 are slidably connected, and the two cutting parts 100 can be fixed to the push frame 000 by bolts, and the two cutting parts 100 both include a trimming blade 110 and a limit block 120, and the limit block 120 is slidably connected to the push frame 000, and two symmetrically arranged pushing parts 200 are installed between the trimming blade 110 and the limit block 120, and the pushing part 200 includes an inner slide plate 210, and the inner slide plate 210 slides The inner slide 210 is rotatably connected to the push frame 000, and an outer clamping plate 220 is welded on the outer side of the inner slide 210. A fixing strip 230 is connected between the inner slide 210 and the outer clamping plate 220 by bolts. The lower end of the fixing strip 230 is rotatably connected to one side of the trimming blade 110, and the other side of the trimming blade 110 is rotatably connected to one end of a movable strip 240. The other end of the movable strip 240 passes through between the inner slide 210 and the outer clamping plate 220 and is slidably connected to the limit block 120. A locking screw 250 is threadedly connected to the outer clamping plate 220.

[0027] When the steel strip processing equipment is used to trim the edge of the steel strip, the processing equipment can be placed on one side of the steel strip so that the trimming blades 110 on the lower side of the two symmetrically arranged cutting parts 100 can be close to the edge of the steel strip. Figure 1 As shown, the push frame 000 can then be pushed from both sides, and the trimming blade 110 can be pushed forward by the push frame 000, so that the trimming blade 110 can remove the burrs left by cutting on both sides of the edge of the steel strip, and can directly cut the single-side edge of the steel strip, thereby completing the shape trimming work of the edge of the steel strip;

[0028] When it is necessary to trim the edges of steel strips with different thicknesses, the two cutting parts 100 can be slid so that the two cutting parts 100 can accurately place the trimming blades 110 close to both sides of the edge of the steel strip, and then the cutting parts 100 can be fixed with bolts, thereby preventing the cutting parts 100 from sliding during the pushing process, thereby causing the trimming blades 110 to move to both sides of the edge of the steel strip, and thus causing the edge of the steel strip to be unable to be trimmed normally;

[0029] When the shape of the edge of the steel strip needs to be adjusted, the limit block 120 can be slid, and the movable bar 240 can be moved left and right close to the push frame 000 by the movement of the limit block 120, so that the corresponding trimming blade 110 can be rotated with the rotation point of the lower end of the fixed bar 230 as the axis, and then the outer clamping plate 220 can be pressed toward the inner slide plate 210 by screwing in the locking screw 250, so that the movable bar 240 can be clamped and limited by the outer clamping plate 220 and the inner slide plate 210, and then the angle of the trimming blade 110 can be adjusted, so that the cutting angle of the steel strip can be adjusted according to the trimming requirements, and then the trimming shape of the edge of the steel strip can be adjusted;

[0030] Secondly, since the movable bars 240 in the two corresponding pushing parts 200 are slidably connected to the corresponding positions of the same limiting block 120, the limiting block 120 can synchronously push and limit the movable bars 240 in the two corresponding pushing parts 200 when moving, thereby ensuring that the two movable bars 240 can be in the same position during the movement process, thereby ensuring that the thrust directions applied by the two pushing parts 200 to the trimming blade 110 are the same, thereby preventing the trimming blade 110 from being deformed or offset due to uneven force during the pushing process, thereby causing the processing equipment to fail to operate normally. The trimming process of the edge of the steel strip occurs; at the same time, since the trimming blade 110 and the limit block 120 are both connected to the two pushing parts 200 at the same time and can remain relatively fixed, that is, after the connection is completed, the trimming blade 110, the limit block 120 and the two pushing parts 200 can form a relatively fixed and stable whole. When the position of the cutting part 100 needs to be adjusted, the trimming blade 110, the limit block 120 and the two pushing parts 200 can move at the same time and remain relatively still, further avoiding deformation or displacement of the trimming blade 110 due to uneven force during the pushing process;

[0031] In addition, since the limit block 120 is fixed to the pushing frame 000 by bolts, the movable bar 240 can be fixed to the inner side of the pushing portion 200 by the limit of the limit block 120, that is, the trimming blade 110 can be fixed by the fixed bar 230 and the movable bar 240 in the same pushing portion 200 at the same time, thereby ensuring that the left and right tilt angles of the trimming blade 110 are fixed; at the same time, the plurality of front and rear arranged pushing portions 200 can fix and limit the front and rear angles of the trimming blade 110, that is, the trimming blade 110 can be fixed by the plurality of fixed bars 230 and the movable bars 240 in the plurality of pushing portions 200 at the same time, thereby avoiding the deviation of the trimming blade 110 when individual fixed bars 230 or movable bars 240 are accidentally damaged, and at the same time, when trimming the steel strip, it can ensure that the trimming blade 110 can be stably connected to the lower side of the cutting portion 100, thereby ensuring the trimming effect of the edge of the steel strip;

[0032] Secondly, during the pushing and moving process of the trimming blade 110, the two pushing parts 200 can simultaneously provide moving support force for the trimming blade 110, that is, during the moving process of the processing equipment along the edge of the steel strip, when the downward pressure on the rear pushing part 200 is greater than that on the front pushing part 200, the lower side of the trimming blade 110 can always fit with the edge of the steel strip that has been trimmed, that is, the trimming blade 110 can move smoothly along the edge of the steel strip without being offset due to uneven cutting of the edge of the steel strip;

[0033] Secondly, the setting of the pushing frame 000 enables the user to push the processing equipment by grasping the edges at both ends of the pushing frame 000 with both hands, thereby reducing the driving force required to push the processing equipment to move, thereby reducing the use requirements of the processing equipment.

[0034] like Figure 4 and 8 As shown:

[0035] The trimming blade 110 is provided with four connecting ports 111, and the fixed strips 230 and movable strips 240 in the pushing portion 200 can be rotatably connected to the corresponding connecting ports 111; the arrangement of the four connecting ports 111 can prevent the trimming blade 110 from interfering with the corresponding fixed strips 230 or movable strips 240 when adjusting the angle. At the same time, since the steel strip is relatively long, the trimming blade 110 is easily damaged due to improper operation when trimming the edge of the steel strip. At this time, the connection of multiple fixed strips 230 and movable strips 240 can share the pressure on a single fixed strip 230 or movable strip 240 when pushing the trimming blade 110 forward to cut burrs or trim edges, thereby extending the service life of a single fixed strip 230 or movable strip 240 and improving the edge trimming of the steel strip by the processing equipment. The continuous service life of the trimming can be prolonged and the failure rate of the processing equipment can be reduced during use. At the same time, the inclination angle of the trimming blade 110 can be adjusted by changing the width between the corresponding connecting ports 111 on both sides of the trimming blade 110, that is, the fixing point of the trimming blade 110 installed on the pushing part 200 can be adjusted by changing the installation position of the fixing bar 230 and the movable bar 240, thereby changing the trimming angle of the trimming blade 110 on the edge of the steel strip, thereby expanding the trimming range of the processing equipment on the edge of the steel strip. At the same time, when there is a need to trim the middle position of the edge of the steel strip, by replacing the trimming blade 110 with a different position of the connecting port 111, the inner sides of the two trimming blades 110 can be completely close together, thereby avoiding the situation where the processing equipment cannot perform shape trimming on the middle side of the edge of the steel strip.

[0036] Further:

[0037] The trimming blades 110 are arranged in groups of two, and the trimming blades 110 of the groups have different curvatures. Thus, by replacing different trimming blades 110 , the trimming requirements of edges with curvatures or other special shapes can be met.

[0038] like Figure 5-6 As shown:

[0039] The inner slide plate 210 is provided with a plurality of threaded holes 201, the outer clamping plate 220 is provided with a plurality of through holes 202 corresponding to the threaded holes 201, and two locking screws 250 are provided, and both of the two locking screws 250 pass through the through holes 202 and are fixedly connected to the corresponding threaded holes 201 through threads; the arrangement of the two locking screws 250 and the plurality of threaded holes 201 enables the locking screws 250 screwed into the threaded holes 201 to be respectively arranged on both sides of the movable bar 240, and then the movable bar 240 can be further limited by the two locking screws 250, so as to avoid the movable bar 240 from being offset during the movement, thereby causing the trimming blade 110 to be offset;

[0040] At the same time, after being screwed into the threaded hole 201, the locking screw 250 can continue to rotate inward, so that the locking screw 250 presses against the side of the pushing frame 000, so that the cutting part 100 can be fixed by the locking screw 250 to prevent the cutting part 100 from continuing to move after the position is adjusted.

[0041] like Fig. 9 As shown:

[0042] A pressure strip 251 is welded on the outside of the locking screw 250, and the length of the pressure strip 251 is less than the distance between two adjacent threaded holes 201; thereby, the outer splint 220 can be further pressed by the pressure strip 251, increasing the area where the outer splint 220 is deformed by force and pressed toward the inner slide 210, thereby increasing the friction between the movable bar 240 and the outer splint 220. At the same time, since the length of the pressure strip 251 is less than the distance between two adjacent threaded holes 201, when the two locking screws 250 need to be screwed into two adjacent threaded holes 201, the two locking screws 250 can be screwed in by rotating the locking screws 250 in sequence without causing interference between the two locking screws 250.

[0043] like Figure 7 As shown:

[0044] The limit block 120 is provided with a limit screw hole 121 , so that the limit block 120 can be fixed by screwing a positioning bolt into the limit screw hole 121 , further ensuring that the cutting part 100 will not move on the pushing frame 000 after the position adjustment is completed.

[0045] Further:

[0046] The limiting block 120 also has two limiting holes 122, and the two movable bars 240 slide inside the limiting holes 122. The two limiting holes 122 are consistent in size with the cross-sections of the corresponding movable bars 240, so that the movable bars 240 can be limited by the limiting holes 122 to ensure that the movable bars 240 always remain vertical during the movement, thereby facilitating the limiting of the movable bars 240 by the limiting block 120.

[0047] like Figure 2 As shown:

[0048] The pushing frame 000 has handles 010 bonded to both ends, so that the user's grip on the pushing frame 000 can be increased through the handles 010. When the user pushes the pushing frame 000 forward, the torque of the pushing frame 000 can be adjusted by holding the handles 010 to ensure that the lower side of the trimming blade 110 can always fit the edge of the steel belt.

[0049] A steel strip processing method comprises the following steps:

[0050] S1: Pressing and cutting the obtained steel strip sheet to obtain a semi-finished steel strip;

[0051] S2: According to the requirements for trimming the edge of the steel strip, a suitable trimming blade 110 is installed on the lower side of the pushing part 200;

[0052] S3: The processing equipment is clamped on one side of the semi-finished steel strip, so that the edge of the trimming blade 110 is clamped on the edge of the semi-finished steel strip;

[0053] S4: Pushing the processing equipment so that the trimming blade 110 can move forward along the edge of the steel strip, removing burrs on the edge of the steel strip and trimming the edge of the steel strip at the same time;

[0054] S5: Repeat steps S3-S4 to process the other side of the semi-finished steel strip, reel in the steel strip with trimmed edges, and complete the processing of the finished steel strip.

[0055] A steel strip is produced by screening and processing through the steel strip processing method.
