DETAILED DESCRIPTION

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0020] Reference Figure 1-Figure 4 As shown, an embodiment of the present invention provides a shearing device, comprising: Rack 1; A lower knife seat 2 and an upper knife seat 5, wherein the lower knife seat 2 can be slidably mounted on the frame 1 and driven by a first crank connecting rod assembly 3, a lower shearing blade 4 is mounted on the lower knife seat 2, and the upper knife seat 5 is movably mounted on the frame 1, and an upper shearing blade 6 is mounted on the upper knife seat 5, and the lower shearing blade 4 and the upper shearing blade 6 are arranged correspondingly; A shearing gap adjustment component is used to adjust the lateral gap between the upper shearing blade 6 and the lower shearing blade 4. The shearing gap adjustment component includes a driving mechanism and a first inclined wedge group and a second inclined wedge group respectively arranged on both sides of the upper knife seat 5. The first inclined wedge group includes a first fixed wedge block 10 and a first movable wedge block 11. The second inclined wedge group includes a second fixed wedge block 13 and a second movable wedge block 14. The first fixed wedge block 10 and the second fixed wedge block 13 are respectively fixedly connected to the frame 1. The first movable wedge block 11 and the first fixed wedge 10 are slidably matched through an inclined surface inclined in the up and down direction. The first movable wedge The side of the second movable wedge 11 away from the first fixed wedge 10 abuts against one side of the upper tool seat 5, the second movable wedge 14 and the second fixed wedge 13 are slidably matched through an inclined surface inclined in the up and down directions, and the side of the second movable wedge 14 away from the second fixed wedge 13 abuts against the other side of the upper tool seat 5, and the driving mechanism is respectively connected to the first movable wedge 11 and the second movable wedge 14, and is used to drive the first movable wedge 11 and the second movable wedge 14 to move respectively, so that the upper tool seat 5 can drive the upper shear blade 6 to move in the direction of increasing or decreasing the lateral gap.

[0021] It should be noted that the upper tool seat 5 is used to install the upper shear blade 6. The length direction of the upper tool seat 5 is consistent with the length direction of the upper shear blade 6, and the width direction of the upper tool seat 5 is consistent with the thickness direction of the upper shear blade 6. In this embodiment, the first inclined wedge group and the second inclined wedge group are respectively located on both sides of the upper tool seat 5, which means that they are respectively located at the two ends of the width direction of the upper tool seat 5.

[0022] Specifically, when the strip material is to be sheared, the strip material is fed into the frame 1 from one side along the feeding direction, and the lower shearing blade 4 is driven by the first crank connecting rod assembly 3 to achieve rapid shearing.

[0023] Before shearing, if the lateral clearance between the upper shearing blade 6 and the lower shearing blade 4 is to be adjusted, the first movable wedge 11 and the second movable wedge 14 can be driven to move by the driving mechanism. Since the first fixed wedge 10 and the second fixed wedge 13 are fixed to the frame 1, the first movable wedge 11 and the first fixed wedge 10 slide against each other with an inclined surface, and the second fixed wedge 13 and the second movable wedge 14 slide against each other with an inclined surface (one side of the first movable wedge 11 is an inclined surface and it slides with the first fixed wedge 10, therefore, the side of the first fixed wedge 10 close to the first movable wedge 11 is also an inclined surface , one side of the second movable wedge block 14 is an inclined surface and it slides with the second fixed wedge block 13, so the side of the second fixed wedge block 13 close to the second movable wedge block 14 is also an inclined surface). Therefore, when the first movable wedge block 11 and the second movable wedge block 14 slide along the inclined surface relative to the first fixed wedge block 10 and the second fixed wedge block 13 respectively, they can simultaneously realize the movement in the vertical and horizontal directions, and then the upper tool holder 5 can be driven to move horizontally by the first movable wedge block 11 and the second movable wedge block 14 to realize the adjustment of the lateral clearance; for example, for the same movable wedge block, its opposite sides are an inclined surface and a vertical surface respectively, such as Figure 1 As shown in the figure, the inclined surface and the vertical surface are arranged roughly in the vertical direction, and the distance between the two surfaces in the horizontal direction is the width of the movable wedge. It can be seen that the width of the movable wedge gradually changes in the up and down direction. Therefore, when the first movable wedge 11 and the second movable wedge 14 move relative to each other in the vertical direction, the change in the width of the movable wedge will cause the upper tool holder 5 to be squeezed in the horizontal direction, so that the upper tool holder 5 will be squeezed and pushed by the first inclined wedge group and the second inclined wedge group in the horizontal direction, as shown in FIG. Figure 1 As shown, the first movable wedge block 11 moves downward and pushes the upper tool seat 5 to the left. At this time, the second movable wedge block 14 can move upward to form an avoidance space for the upper tool seat 5, thereby completing the leftward movement of the upper tool seat 5 to drive the upper shear blade 6 to move to the left. At this time, the lateral gap between the upper shear blade 6 and the lower shear blade 4 is reduced. If the lateral gap between the upper shear blade 6 and the lower shear blade 4 is to be increased, the first movable wedge block 11 and the second movable wedge block 14 can be driven in reverse. The first inclined wedge group and the second inclined wedge group cooperate with the upper tool seat 5, thereby converting the vertical movement brought by the driving mechanism into horizontal movement, thereby adjusting the lateral gap between the upper shear blade 6 and the lower shear blade 4.

[0024] In this embodiment, the lower knife seat 2 is slidably mounted on the frame 1, and driven to slide up and down by the first crank connecting rod assembly 3, the lower knife seat 2 is equipped with a lower shear blade 4, the upper knife seat 5 is movably mounted on the frame 1, and the upper shear blade 6 is mounted on the upper knife seat 5, and the lower shear blade 4 and the upper shear blade 6 are arranged correspondingly. In this way, the lower knife seat 2 and the upper knife seat 5 are both movable, which improves the shearing flexibility. In order to achieve the purpose of adjusting the lateral gap of the shear blade, a shearing gap adjustment component is provided, and the shearing gap adjustment component includes The driving mechanism and the first inclined wedge group and the second inclined wedge group are respectively arranged between the two sides of the upper knife seat 5 and the frame 1. Since the second inclined wedge group includes a second fixed wedge block 13 and a second movable wedge block 14, the first fixed wedge block 10 and the second fixed wedge block 13 are respectively fixedly connected to the frame 1, and the first movable wedge block 11 and the first fixed wedge block 10 slide against each other using inclined surfaces. The side of the first movable wedge block 11 away from the first fixed wedge block 10 is a vertical surface and abuts against one side of the upper knife seat 5. The second fixed wedge block 13 and The second movable wedge blocks 14 slide against each other with inclined surfaces, and the side of the second fixed wedge block 13 away from the second movable wedge block 14 is a vertical surface and abuts against the other side of the upper tool seat 5. When the first movable wedge block 11 and the second movable wedge block 14 are driven by the driving structure to move in the vertical direction, the upper tool seat 5 will be squeezed by the first movable wedge block 11 in the first inclined wedge group or the second movable wedge block 14 in the second inclined wedge group in the width direction. Correspondingly, at this time, the second movable wedge block 14 in the second inclined wedge group or the first movable wedge block 11 in the first inclined wedge group An avoidance space for the upper knife seat 5 will be formed synchronously, thereby converting the vertical sliding of the first movable wedge 11 and the second movable wedge 14 driven by the driving mechanism into horizontal movement of the upper knife seat 5, so that the upper knife seat 5 drives the upper shear blade 6 to move in the direction of increasing or decreasing the lateral gap, thereby accurately adjusting the lateral gap between the upper shear blade 6 and the lower shear blade 4 to meet the shearing requirements of strips including high-end high-strength alloys, ensuring the neatness of the edges of the sheared part, and not requiring manual shutdown operations, thereby improving shearing efficiency and shearing quality.

[0025] The special properties of high-strength alloys such as titanium alloys require that the shear blades must be adjusted accurately and stably with an error within 0.5 mm to ensure that the edges of the sheared parts are flush and the cut length is accurate. The present invention can meet the "harsh" requirements of high-strength alloys for shearing equipment. While meeting the same functional requirements, the shearing equipment in the present invention can adopt a crank-connecting rod mechanism, and the lower knife seat 2 and the upper knife seat 5 are both sports-type. Compared with similar shearing equipment, the weight can be reduced by more than 20%, the cost performance is high, and it has a strong market promotion value.

[0026] like Figure 6 and Figure 7As an optional embodiment of the present invention, the upper tool holder 5 is symmetrically provided with slide grooves on both sides, and the slide grooves extend in the vertical direction. The first movable wedge 11 is slidably connected to the slide groove on one side of the upper tool holder 5, and the side of the first movable wedge 11 away from the first fixed wedge 10 abuts against the bottom surface of the slide groove. The second movable wedge 14 is slidably connected to the slide groove on the other side of the upper tool holder 5, and the side of the second movable wedge 14 away from the second fixed wedge 13 abuts against the bottom surface of the slide groove. That is, the upper tool holder 5 is slidably matched with the first movable wedge 11 and the second movable wedge 14.

[0027] Specifically, along the width direction, sliding grooves are symmetrically opened on both sides of the upper knife seat 5, and for each inclined wedge group, a corresponding sliding groove is provided on the upper knife seat 5. Since the second movable wedge block 14 and the first movable wedge block 11 are respectively abutted against the side surfaces of the two sides of the upper knife seat 5, the second movable wedge block 14 and the first movable wedge block 11 are abutted against the inner end surfaces of the sliding groove. In this way, by moving the first movable wedge block 11 and the second movable wedge block 14, the upper knife seat 5 can be moved in the direction of increasing or decreasing the lateral gap with the upper shearing blade 6. Before shearing, if the vertical spacing between the lower shearing blade 4 and the upper shearing blade 6 is to be adjusted, since the first movable wedge block 11 is slidably connected to the sliding groove on one side of the upper knife seat 5 and the sliding groove on the other side of the upper knife seat 5 is slidably connected, the upper knife seat 5 is slidably arranged between the first movable wedge block 11 and the second movable wedge block 14, so that it can be moved vertically (such as vertical spacing between the first movable wedge block 11 and the second movable wedge block 14) along the first movable wedge block 11 and the second movable wedge block 14. Figure 7 , or swipe up or down in the

[0028] In this optional embodiment, the first movable wedge 11 and the second movable wedge 14 cooperate with the sliding groove of the upper tool seat 5 to achieve abutment and sliding cooperation. In this way, the upper tool seat 5 and the first movable wedge 11 and the second movable wedge 14 achieve mutual sliding cooperation, and the first movable wedge 11 and the second movable wedge 14 can be driven to move by the driving mechanism to achieve horizontal lateral movement of the upper tool seat 5 to increase or decrease the lateral gap between the upper shear blade 6 and the lower shear blade 4.

[0029] like Figure 3As shown, as an optional embodiment of the present invention, the inclined surface of the first movable wedge block 11 and the inclined surface of the second movable wedge block 14 are parallel to each other, or the inclined surface of the first movable wedge block 11 and the inclined surface of the second movable wedge block 14 form a fixed angle. When the inclined surface of the first movable wedge block 11 and the inclined surface of the second movable wedge block 14 are parallel to each other, the driving mechanism is used to drive the first movable wedge block 11 and the second movable wedge block 14 to move in the same direction respectively, or when the inclined surface of the first movable wedge block 11 and the inclined surface of the second movable wedge block 14 form a fixed angle, the driving mechanism is used to drive the first movable wedge block 11 and the second movable wedge block 14 to move in opposite directions respectively.

[0030] Specifically, in Figure 3 In (a), when the inclined surface of the first movable wedge block 11 and the inclined surface of the second movable wedge block 14 are parallel to each other, if the upper tool holder 5 is to be pushed to one side, the second movable wedge block 14 and the first movable wedge block 11 should move in the same direction, and the subsequent corresponding driving units 16 should generally be arranged on different sides. If the upper tool holder 5 is to be pushed to the right, the second movable wedge block 14 and the first movable wedge block 11 should both move downward. Conversely, if the upper tool holder 5 is to be pushed to the left, the second movable wedge block 14 and the first movable wedge block 11 should both move upward.

[0031] Specifically, in Figure 3 In (b), when the inclined surface of the first movable wedge block 11 and the inclined surface of the second movable wedge block 14 form an angle opening upward, if the upper tool holder 5 is to be pushed to one side, the second movable wedge block 14 and the first movable wedge block 11 should move toward each other, and the corresponding driving unit 16 can be set on the same side. If the upper tool holder 5 is to be pushed to the right, the second movable wedge block 14 should move downward and the first movable wedge block 11 should move upward. Conversely, if the upper tool holder 5 is to be pushed to the left, the second movable wedge block 14 should move upward and the first movable wedge block 11 should move downward.

[0032] The difference in moving directions of the first movable wedge block 11 and the second movable wedge block 14 caused by the above vertical and inclined surface distribution can be selected for practical applications. The above-mentioned methods can meet the requirement of making the upper tool seat 5 drive the upper shear blade 6 to move in the direction of increasing or decreasing the lateral gap.

[0033] It should be noted that a window 24 is provided in the middle portion of the frame 1, and the lower knife seat 2 and the upper knife seat 5 are both arranged in the window 24 to ensure a compact structure.

[0034] like Figure 1As shown, as an optional embodiment of the present invention, the first inclined wedge group and the second inclined wedge group are symmetrically arranged with the central axis of the upper tool seat 5 as the symmetry axis, and the driving mechanism includes a first screw rod 12 threadedly connected to the first movable wedge block 11, a second screw rod 15 threadedly connected to the second movable wedge block 14, and a driving unit 16, and the driving unit 16 is used to drive the first screw rod 12 and the second screw rod 15 to rotate synchronously.

[0035] Specifically, in Figure 1 In the figure, along the thickness direction of the frame 1, the left side is the second inclined wedge group, and the second inclined wedge group is symmetrically arranged along both ends. Similarly, the right side is the first inclined wedge group, and the first inclined wedge group is symmetrically arranged along both ends. The driving unit 16 can drive the first screw rod 12 and the second screw rod 15 to rotate synchronously, thereby realizing the same direction movement or opposite direction movement of the first movable wedge block 11 and the second movable wedge block 14.

[0036] In this optional embodiment, the driving unit 16 can be provided separately to ensure the same direction or opposite direction movement of the first movable wedge 11 and the second movable wedge 14, such as providing a driving motor and a reducer separately.

[0037] According to the above statements, two of the second inclined wedge group and two of the first inclined wedge group can be provided, and each is symmetrically distributed at the two ends of the frame 1, so as to ensure that the upper tool holder 1 is subjected to uniform force.

[0038] like Figure 8 As shown, as a preferred embodiment of the present invention, the driving unit 16 includes a driving motor 161, a gear group and a coupling group. The coupling group is rotatably installed on the frame 1, and the coupling group is respectively connected to the first screw rod 12 and the second screw rod 15 through the gear group. The driving motor 161 is used to drive the coupling group to rotate.

[0039] The connecting shaft group includes a first connecting shaft 162, an intermediate connecting shaft 163 and a second connecting shaft 164. Since the second inclined wedge group and the first inclined wedge group can be provided with two each, correspondingly, the first screw rod 12 and the second screw rod 15 can be provided with two each. The first connecting shaft 162 and the second connecting shaft 164 are respectively provided with two each and each is symmetrically arranged with the central axis of the upper tool holder 5 as the symmetry axis. The driving motor 161 is also connected to one of the two first connecting shafts 162 through a gear group to transmit torque. One end of each second connecting shaft 164 is connected to one end of each first connecting shaft 162 through a gear group, and the other end of the second connecting shaft 164 is connected to the second screw rod 15 through a gear group. The intermediate connecting shaft 163 is provided between the two first connecting shafts 162. The two first connecting shafts 162 are connected to the intermediate connecting shaft 163 through a gear group, and the intermediate connecting shaft 163 is also connected to the two first screw rods 12 through a gear group transmission connection.

[0040] Specifically, by starting the driving motor 161, it drives the first connecting shaft 162 directly connected to it to rotate, and then drives the second connecting shaft 164 at one end and the middle connecting shaft 163 to rotate, and then drives the first connecting shaft 162 and the second connecting shaft 164 at the other end to rotate, so as to achieve driving Figure 8 The synchronous rotation between the two first screw rods 12 and the two second screw rods 15, the rotation directions of the first screw rods 12 and the second screw rods 15 are consistent, but the rotation directions of the first screw rods 12 and the second screw rods 15 are opposite, so that during the synchronous rotation, one of the first movable wedge block 11 and the second movable wedge block 14 rises and the other falls. It should be noted that since the first movable wedge block 11 and the second movable wedge block 14 are both slidably matched with the upper tool holder 5, it is generally not necessary to separately set a device for limiting the rotation of the first movable wedge block 11 and the second movable wedge block 14. Of course, a guide rod can be set vertically, and the guide rod passes through the first movable wedge block 11. As for the limit of the up and down feeding of the first movable wedge block 11 and the second movable wedge block 14, limit blocks (not shown in the figure) can be set at the upper and lower ends.

[0041] In this optional embodiment, the gear set used for transmission between the two shafts involved in the drive motor 161, the first connecting shaft 162, the intermediate connecting shaft 163 and the second connecting shaft 164 can be completed by a bevel gear pair (including an active bevel gear and a passive bevel gear, Figure 8 (not shown), and the transmission ratios of all bevel gear pairs can be selected to be the same, and ultimately it is necessary to ensure that the rotation speeds of the first screw rod 12 and the second screw rod 15 are consistent. The above only requires one drive motor 161 to drive the transmission of at least 4 screw rods.

[0042] like Figure 4 , Figure 5As shown, as an optional embodiment of the present invention, it also includes a pinch roller assembly 18, and the pinch roller assembly 18 includes a first mounting plate 181, a feeding cylinder 182, a second mounting plate 183, a pinch roller 184, a guide rack shaft 185 and a synchronous gear 186. The first mounting plate 181 is fixedly mounted on the frame 1. Optionally, the first mounting plate 181 is fixedly mounted on the frame 1 via a pinch roller assembly seat 17.

[0043] The feeding cylinder 182 is fixedly mounted on the first mounting plate 181, the second mounting plate 183 is fixedly mounted on the protruding end of the feeding cylinder 182 and is slidably connected to the first mounting plate 181 through the guide rack shaft 185, the pinching roller 184 is rotatably mounted on the second mounting plate 183, an encoder is mounted on the second mounting plate 183, a conveying roller 19 is also provided on the frame 1, at least an entrance active roller 20 is mounted on the conveying roller 19, and the pinching roller 184 and the entrance active roller 20 are used to pinch and convey materials such as strips.

[0044] Specifically, after the incoming strip passes through the pinch roller 184, the pinch roller 184 moves downward to clamp the strip (such as steel strip), and the strip moves forward under the drive of the entrance active roller 20 of the conveyor roller 19, that is, the pinch roller 184 and the entrance active roller 20 are linked and controlled to achieve smooth feeding. The encoder can identify the speed of the strip passing through the pinch roller 184, and then feed back to the controller. The controller increases or decreases the rotation speed of the entrance active roller 20 based on the speed, that is, determines the feeding speed to ensure that the subsequent incoming strip can enter and be sheared in an orderly manner as set in advance.

[0045] In this optional embodiment, by setting the pinching roller assembly 18 and cooperating with the inlet active roller 20, it is possible to achieve orderly and smooth feeding to the inlet, which is convenient for shearing and achieves the function of precise pinching and feeding.

[0046] As an optional embodiment of the present invention, the clamping roller assembly 18 also includes a synchronization gear 186 rotatably mounted on the first mounting plate 181, and at least two guide rack shafts 185 are provided. The synchronization gear 186 is arranged in a one-to-one correspondence with the guide rack shaft 185 and meshes with the guide rack shaft 185.

[0047] Both ends of the guide rack shaft 185 are rod-shaped structures, with a rack in the middle, the rack is meshed with a synchronous gear 186, and at least two of the synchronous gears 186 are coaxially rotatably mounted on the first mounting plate 181 (can be indirectly fixed relative to the first mounting plate 181).

[0048] Specifically, in order to improve the effect of clamping the strip after the clamping roller 184 is pressed down, it is necessary to ensure that the bottom of the clamping roller 184 is horizontal, or flush with the top of the inlet active roller 20. At this time, by setting a synchronous gear 186, the synchronous gear 186 is engaged with the guide rack shaft 185, so that under the action of the feeding cylinder 182, the two ends of the second mounting plate 183 can be extended synchronously, and then the two ends of the clamping roller 184 can also be extended synchronously.

[0049] In this optional embodiment, in order to prevent the feeding cylinders 182 on both sides from extending inconsistently, a guide rack shaft 185 and a synchronous gear 186 are provided, so that the clamping roller 184 can always be extended in a horizontal state, and the strip is flatly clamped between the clamping roller 184 and the inlet active roller 20.

[0050] like Fig.10 and Fig.12 As shown, as an optional embodiment of the present invention, it also includes a material pushing assembly, which includes a tail material flattening assembly 21 and a tail material pushing assembly 22. The tail material flattening assembly 21 is used to flatten the tail of the material entering from the feeding direction, and the tail material pushing assembly 22 is used to push the flattened tail of the material to the position of the inlet active roller 20.

[0051] Specifically, the material pusher consists of two parts. First, the material tail flattening component 21 completes the up and down vertical movement, and then the material tail pushing component 22 completes the horizontal movement after it is in place, thereby achieving smooth shearing of the material tail after flattening, which is beneficial for processing uneven material tails such as warping, realizing automatic pushing of the material tail, and improving the utilization rate of the material tail.

[0052] like Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown in FIG. 1 , as an optional embodiment of the present invention, the tail pushing assembly 22 includes an adjusting cylinder 221 , a movable seat 222 , a transfer seat 224 , a pushing cylinder 225 and a pushing plate 227 . The regulating cylinder 221 is fixedly connected to the frame 1 (through the first mounting seat), the movable seat 222 is fixedly installed at the protruding end of the regulating cylinder 221 and slidably cooperates with the first mounting seat, and the transfer seat 224 is fixedly connected to the movable seat 222. Therefore, it is equivalent to that the transfer seat 224 is fixedly connected to the protruding end of the regulating cylinder 221 and slidably cooperates with the frame 1, the pushing cylinder 225 is fixedly installed on the transfer seat 224, and the pushing plate 227 is fixedly installed on the protruding end of the pushing cylinder 225 and slidably connected to the transfer seat 224. The push plate 227 is arranged vertically, and the tail flattening assembly 21 includes a pressure cylinder 211 and a pressure plate 214. The pressure cylinder 211 is fixedly connected to the upper knife seat 5 (through a second mounting seat), and the pressure plate 214 is fixedly installed on the protruding end of the pressure cylinder 211 and slidingly cooperates with the second mounting seat (equivalent to the pressure plate 214 being fixedly installed on the protruding end of the pressure cylinder 211 and slidingly cooperates with the upper knife seat 5). Along the feeding direction, the push plate 227 and the pressure plate 214 are arranged sequentially. In layman's terms, the pressure plate 214 is arranged on the inner side opposite to the push plate 227.

[0053] For the tail pushing assembly 22, the movable seat 222 and the transfer seat 224 are fixedly connected by a column, and a second guide member 223 is vertically fixed on the movable seat 222, and the second guide member 223 is slidably connected to the second guide sleeve 228 fixed on the second mounting seat, so that the movable seat 222 and the first mounting seat can be slidably matched, and multiple groups of the second guide member 223 and the second guide sleeve 228 can be set; in addition, a third guide member 226 is vertically fixed to the push plate 227, and the third guide member 226 is slidably connected to the guide slide fixed on the transfer seat 224.

[0054] For the tail flattening assembly 21, a first guide member 212 is vertically fixed on the material pressing plate 214, and a first guide sleeve 213 is fixed on the second mounting seat. The first guide member 212 is slidably connected with the first guide sleeve 213 to achieve sliding cooperation between the material pressing plate 214 and the second mounting seat. Multiple groups of the first guide member 212 and the first guide sleeve 213 can be set.

[0055] Specifically, Fig.12 As shown, since the tail of the material may present different shapes such as curling, first start the pressing cylinder 211, adjust the protruding end of the pressing cylinder 211 to extend downward, drive the pressing plate 214 to move downward, so that the curled tail of the material is pressed downward, and the end formed downward by the pressing plate 214 is higher than the height of the inlet active roller 20 (which can be the thickness of the strip plus 1~2mm).

[0056] Then, through the action of the material tail pushing component 22, when the material tail needs to be pushed, the transfer seat 224 is first extended downward to a position roughly flush with the inlet active roller 20 through the action of the adjusting cylinder 221, and then the pushing cylinder 225 controls the pushing plate 227 to extend, pushing the material tail forward (towards the discharge direction). At this time, the bottom of the pushing plate 227 is slightly higher than the top of the inlet active roller 20. Since the material tail has been pressed down, the material tail is directly pushed to the top of the inlet active roller 20 through the action of the pushing plate 227, so that it can smoothly enter between the lower shear blade 4 and the upper shear blade 6 to complete the shearing. After the material tail is sheared, it generally slides through the discharge chute 23 to the designated container (not shown in the figure).

[0057] In this optional embodiment, the material pusher consists of two parts. First, the material tail flattening component 21 completes the up and down vertical movement, and then the material tail pushing component 22 completes the horizontal movement after it is in place. Both can be controlled by a cylinder to achieve smooth shearing of the material tail.

[0058] like Figure 2 , Figure 4 and Figure 8 As an optional embodiment of the present invention, it also includes a second crank-connecting rod assembly 7, which is used to drive the upper tool seat 5 to move up and down to adjust the vertical distance between the upper tool seat 5 and the lower tool seat 2.

[0059] Specifically, the second crank-connecting rod assembly 7 includes a third connecting rod 71, a fourth connecting rod 72 and a second driving connecting rod 73, one end of the third connecting rod 71 is hinged to the frame 1, and the other end is hinged to one end of the fourth connecting rod 72, and the other end of the fourth connecting rod 72 is hinged to the upper tool holder 5, the third connecting rod 71 and the fourth connecting rod 72 are provided with two parallel groups (the second driving connecting rod 73 is also parallel to the upper tool holder 5), one end of the second driving connecting rod 73 is coaxially hinged to the positions where the third connecting rod 71 and the fourth connecting rod 72 are connected (two hinge points), and the other end is installed on the protruding end of the second hydraulic cylinder 8, and the second hydraulic cylinder 8 is installed on the frame 1. Through the extension and retraction of the protruding end of the second hydraulic cylinder 8, the third connecting rod 71 and the fourth connecting rod 72 can be driven to swing through the second driving connecting rod 73, thereby driving the upper tool holder 5 to move up and down to complete the adjustment of the position of the upper tool holder 5.

[0060] It should be noted that there is a certain axial margin at the position where the fourth connecting rod 72 and the upper tool holder 5 are coaxially hinged, so as to meet the requirement of horizontal movement (displacement) of the upper tool holder 5 .

[0061] In this embodiment, the running speed of the second crank connecting rod assembly 7 is faster than the vertical moving speed of the shears. When shearing is required, the upper knife seat 5 is first moved to the limit position by the second hydraulic cylinder 8. After it is in place, the lower knife seat 2 runs to complete the shearing, which reduces the movement stroke of the upper and lower shear blades 4 of the lower knife seat 2. After it is in place, the lower shear blade 4 can achieve rapid shearing under the drive of the first crank connecting rod assembly 3 to complete the rapid shearing of strips including high-strength alloys, thereby improving the shearing efficiency. In an optional embodiment, the first crank-connecting rod assembly 3 includes a first connecting rod 31, a second connecting rod 32 and a first driving connecting rod 33, one end of the second connecting rod 32 is hinged to the frame 1, and the other end is hinged to one end of the first connecting rod 31, the other end of the first connecting rod 31 is hinged to the lower knife seat 2, the first connecting rod 31 and the second connecting rod 32 are provided with two parallel groups (the first driving connecting rod 33 is also parallel to the lower knife seat 2), one end of the first driving connecting rod 33 is coaxially hinged to the positions where the first connecting rod 31 and the second connecting rod 32 are connected (two hinge points), and the other end is installed on the protruding end of the first hydraulic cylinder 9, the first hydraulic cylinder 9 is installed on the frame 1, and through the extension and retraction of the protruding end of the first hydraulic cylinder 9, the first driving connecting rod 33 can drive the first connecting rod 31 and the second connecting rod 32 to swing, thereby driving the reciprocating movement of the lower knife seat 2, driving the lower shear blade 4 to reciprocate, and with the cooperation of the predetermined upper shear blade 6, completing the shearing of materials such as strips.

[0062] It should be noted that both the first hydraulic cylinder 9 and the second hydraulic cylinder 8 are preferably hydraulically driven, and the driving force generated by the first hydraulic cylinder 9 is greater than the driving force generated by the second hydraulic cylinder 8 .

[0063] In summary, the shearing equipment of the present invention can be lightweight, have stable and reliable performance, and have a novel structure. It can also realize functions such as automatic, accurate and efficient adjustment of the shear blade gap, rapid shearing, automatic tail pushing, and precise feeding, and can meet the shearing requirements for high-strength alloy plates in the unit process.
