Description

Technical Field

[0001] The invention belongs to the technical field of plate processing, in particular to a lifting shearing machine which is convenient for unloading. Background Art

[0002] In the processing of steel coils and steel plates, the steel coils and steel plates in a complete state need to be sheared into uniform steel sheets by a shearing machine, and then the steel sheets can be bent, punched and processed. When cutting steel coils and steel plates, the automatic lifting shearing machine can quickly and conveniently cut the unfolded steel coils and steel plates into uniform-sized steel sheets.

[0003] When using a lifting plate rolling machine to cut steel coils and steel plates, it is necessary to use a feeding device to transport the steel coils and steel plates to the shearing machine. During the alternating operation of the feeding device and the shearing machine, the steel coils and steel plates are cut into steel sheets of uniform size, and the cut steel coils and steel plates are transported and unloaded. In actual application, it is found that the existing shearing machines lack a guiding and positioning mechanism for the steel coils and steel plates after cutting. The steel sheets formed after cutting are in a free-falling state under the action of gravity, which not only easily leads to the scattered stacking of the steel sheets, increasing the difficulty of later sorting, but also because the edges of the cut steel sheets are relatively sharp, collisions and sliding are likely to occur between multiple steel sheets and between the steel sheets and the ground during the free fall process, which increases the probability of scratches on the surface of the steel sheets, bending and deformation of the steel sheets, and the freely scattered steel sheets also have certain safety hazards.

[0004] In order to enhance the stacking effect of steel sheets formed after cutting in the related art, most of them transport and stack the cut steel sheets by setting a conveying track with a limiting mechanism, thereby enhancing the stacking effect of the cut steel sheets. However, on the one hand, during operation, although the stacking effect of the steel sheets is enhanced, the steel sheets are still in a free fall state during the stacking process. When the steel sheets fall on the stacked steel sheets, they collide with each other, forming extrusion noise pollution. On the other hand, during the falling process, the steel plates not only have relative movement in the vertical direction, but also relative movement in the parallel direction, which causes scratches and deformation on the surface of the steel plates due to friction, scratches, impacts and other reasons.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 6 As shown, the lifting shearing machine for convenient unloading of materials described in the present invention comprises a frame 1, the frame 1 is a frame-type structure, and a hydraulic shearing assembly is installed on the frame 1;

[0039] The hydraulic shearing assembly includes a lift 11, which is mounted on a frame 1 and is a hydraulic lift system;

[0040] A knife holder 12 is fixedly mounted at the bottom of the lift 11, an upper blade is fixedly mounted on the knife holder 12, and a lower blade is fixedly mounted on the frame 1, and the upper blade corresponds to the lower blade;

[0041] It also includes a stacking component, which is installed on the frame 1 and is used to stack the cut plates;

[0042] The stacking assembly includes a guide rod 21, a mounting frame 2 is fixedly mounted on the discharging side of the frame 1, and two parallel sets of guide rods 21 are rotatably connected to the mounting frame 2;

[0043] A rotating belt 22, the two guide rods 21 in the same group are sleeved with a rotating belt 22, and the rotating belt 22 is made of an elastic rubber material with steel wire wrapped inside;

[0044] Support plates 23, the rotating belt 22 is provided with evenly distributed support plates 23, the support plates 23 are used to support the cut plates;

[0045] An adjustment component, which is installed on the frame 1 and the stacking component, and is used to adjust the stacking component to enhance the stacking effect of the plates;

[0046] When shearing steel coils, steel plates, etc., the shearing machine program is adjusted, and then the material is fed into the shearing machine. The material feeding position is observed by sensors or manually, and the hydraulic shearing assembly is started. When the hydraulic shearing assembly is working, the lift 1 is controlled to descend by the hydraulic lifting system, thereby driving the knife frame 12 to move downward. During the downward movement of the knife frame 12, the upper blade and the lower blade gradually approach each other, and finally the material between the upper blade and the lower blade is sheared. When the shearing is completed, the plate formed after the cutting has a tendency to fall under the action of gravity. At this time, the stacking assembly forcibly guides the plate, and then the plate is neatly stacked. Specifically, during the material feeding process, the material extends toward the guide rod 21 through the gap between the upper blade and the lower blade, and finally contacts the support plate 23 on the rotating belt 22. The rotating belt 22 and the support plate 23 limit and support the material. When the material is cut into plates, the plates fall completely on the support plate 23. Since the guide rod 21 is rotatably connected to the mounting frame 2, and the rotating belt 22 The guide rod 21 is sleeved on the guide rod 21. Therefore, when the support plate 23 on one side of the rotating belt 22 is stressed, the rotating belt 22 is unbalanced, causing the rotating belt 22 to drive the guide rod 21 to rotate. During the rotation, the plate gradually approaches the ground until the plate is separated from the support plate 23 and completely falls to the ground. In this embodiment, the middle part of the guide rod 21 is gear-shaped, and the rotating belt 22 is meshed with the guide rod 21. Therefore, when the rotating belt 22 rotates, the guide rod 21 rotates synchronously, thereby causing the guide rod 21 and the rotating belt to rotate. 22 temperature rotates, and in other embodiments of the present invention, the rotating belt 22 and the guide rod 21 can also be slidably connected. When the plate acts on the support plate 23, under the action of gravity, the rotating belt 22 and the guide rod 21 slide. The rotatable setting of the guide rod 21 can further reduce the friction force when the rotating belt 22 and the guide rod 21 slide relative to each other, so that the rotating belt 22 can continuously reciprocate to guide and limit the falling plate, so that the plate falls downward more smoothly.

[0047] The present invention sets a stacking component. Before the plate is cut, the support plate 23 and the rotating belt 22 assist the frame 1 to enhance the supporting effect on the material. After cutting, when the gravity of the plate completely acts on the support plate 23, the rotating belt 22 and the guide rod 21 rotate under the action of gravity, thereby guiding the falling of the plate. In the process of falling, the support plate 23 always supports the plate, so that the plate always falls in a straight state. At the same time, due to the friction between the guide rod 21 and the rotating belt 22 during the rotation process, the falling speed of the plate is buffered, the impact force of the plate when it falls is reduced, and the noise when the plates are stacked and fitted is reduced.

[0048] As a preferred embodiment of the present invention, the adjustment assembly includes a support frame 24, and each group of guide rods 21 is commonly mounted with a support frame 24 at one end away from the mounting frame 2;

[0049] The two support frames 24 are staggered, and the two support frames 24 are provided with a slide groove 25, and a block 26 is slidably installed in the slide groove 25, and the block 26 is used to connect the two support frames 24;

[0050] An adjusting slot 3 and an adjusting block 31, wherein the mounting frame 2 is provided with an adjusting slot 3, wherein an adjusting block 31 is slidably installed in the adjusting slot 3, and the guide rod 21 is rotatably connected to the adjusting block 31;

[0051] Before the cut plate is forcibly guided by the stacking component, since the size and width of the plate cutting vary with the process, an adjustment component is set to adjust the stacking component, thereby making the stacking component and the plate more compatible. Specifically, before cutting, a support frame 24 is set so that both ends of the guide rod 21 are supported by the mounting frame 2 and the support frame 24 respectively, so that the guide rod 21 is relatively stable. Subsequently, when the width of the material to be cut is determined, the guide rod 21 is manually pushed, so that the guide rod 21 drives the adjustment component to move. The node block 31 and the support frame 24 move, and then adjust the distance between the two groups of guide rods 21, so that the distance between the two groups of guide rods 21 is more matched with the width of the material. During the adjustment process, the two support frames 24 move away from or close to each other. The setting of the slide groove 25 makes it more convenient for the two support frames 24 to move relative to each other, and the block 26 is engaged in the slide groove 25 of the two support frames 24. Through the shape restriction between the block 26 and the slide groove 25, the two support frames 24 are connected to each other and can only move in one direction, thereby enhancing the stability of the support frames 24.

[0052] As a preferred embodiment of the present invention, the adjustment assembly further includes a driving screw 4, the driving screw 4 is rotatably connected to the adjustment slot 3, the threads at both ends of the driving screw 4 are in opposite directions, the driving screw 4 and the adjustment block 31 are both spirally driven, one end of the driving screw 4 extends to the outside of the mounting frame 2, and a rotating wheel 41 is fixedly installed at the end of the driving screw 4;

[0053] By setting the driving screw 4 and the rotating wheel 41, when adjusting the spacing between the two groups of guide rods 21, the rotating wheel 41 is manually rotated, so that the rotating wheel 41 drives the driving screw 4 to rotate. Since the adjusting block 31 is restricted by the adjusting groove 3 and is spirally transmitted with the driving screw 4, during the rotation of the driving screw 4, the two adjusting blocks 31 in the same adjusting groove 3 produce relative movement, thereby facilitating the adjustment of the spacing between the two groups of guide rods 21. At the same time, due to the spiral transmission between the driving screw 4 and the adjusting block 31, when the driving screw 4 does not rotate, the driving screw 4 and the adjusting block 31 are self-locking, thereby fixing the spacing of the adjusting blocks 31, thereby enhancing the stability of the guide rods 21 after adjustment.

[0054] As a preferred embodiment of the present invention, the adjusting slot 3 and the driving screw 4 are both designed in plural numbers, and the plurality of driving screws 4 are driven by chains;

[0055] By designing a plurality of adjustment slots 3 and drive screws 4, when adjusting, the drive screws 4 and the adjustment slots 3 correspond to the number of the same group of guide rods 21, and the multiple drive screws 4 are driven by a chain. Therefore, when the rotating wheel 41 connected to one of the drive screws 4 is manually transferred, under the transmission effect of the chain, the multiple drive screws 4 are caused to rotate, and then the distance between the two groups of guide rods 21 is adjusted. Compared with manual adjustment one by one, the synchronous adjustment is not only faster and simpler to operate, but also the distance adjustment between the two groups of guide rods 21 is more precise, thereby avoiding the situation where there is a deviation in the position of the same group of guide rods 21.

[0056] As a preferred embodiment of the present invention, the adjustment assembly further includes a universal wheel 42, and a universal wheel 42 with a locking function is installed at the bottom of the support frame 24;

[0057] The guide rod 21 is composed of an extension tube 27 and a connecting rod 28, the extension tube 27 and the connecting rod 28 are arranged alternately, the connecting rod 28 is slidably connected in the extension tube 27, the rotating belt 22 corresponds to the extension tube 27 one by one, and both are sleeved on the extension tube 27;

[0058] During the adjustment process, the guide rod 21 is composed of an extension tube 27 and a connecting rod 28, so that the guide rod 21 has a telescopic function. Therefore, in the adjustment stage before cutting, the staff manually pulls the support frame 24, and the support frame 24 moves under the action of the universal wheel 42 at the bottom, thereby adjusting the distance between the support frame 24 and the mounting frame 2. During this process, the guide rod 21 located between the support frame 24 and the mounting frame 2 is subjected to a pulling force or a pushing force, thereby causing the distance between two adjacent extension tubes 27 to change, and then by adjusting the gap of the extension tube 27, the gap of the rotating belt 22 is adjusted. When the adjustment is completed, the universal wheel 42 is locked, thereby causing the distance between the mounting frame 2 and the extension frame to be locked, so that the stacking assembly can adapt to plates of different lengths and enhance the application range of the stacking assembly. At the same time, in other embodiments of the present invention, a spring is fixedly installed in the inner cavity of the extension tube 27, and the spring is fixedly connected to the connecting rod 28. On the one hand, the telescopic stability of the guide rod 21 composed of the extension tube 27 and the connecting rod 28 is enhanced, and on the other hand, it is also convenient to adjust the spacing between the extension tubes 27.

[0059] As a preferred embodiment of the present invention, the stacking assembly further includes a deflection slot 5, the deflection slot 5 is opened on the rotating belt 22, the support plate 23 is rotatably connected to the deflection slot 5, and in the initial state, the support plates 23 on one side of the rotating belt 22 close to each other are rotated to the outside of the deflection slot 5;

[0060] By setting the deflection slot 5, during the rotation of the rotating belt 22, after the rotating belt 22 passes over the guide rod 21, under the action of gravity, the support plate 23 connected to the deflection slot 5 rotates, and is finally restricted by the deflection slot 5, so that the support plate 23 and the rotating belt 22 are at a 90-degree angle. At this time, the support plate 23 is parallel to the plate. During the material feeding process, the material moves above the support plate 23. After the plate is cut and formed, the plate completely falls on the support plate 23 under the action of gravity, and is at the support plate 23 and the rotating belt 2 2, they are gradually stacked on the ground. As the stacking height of the plates on the ground increases, the support plate 23 may be hindered by the stacked plates during its downward movement. At this time, under the action of resistance, the support plate 23 rotates into the deflection groove 5, thereby preventing the stacked plates from hindering the operation of the rotating belt 22. At the same time, the support plate 23 is deflectable. During the initial design, the distance between the bottom of the rotating belt 22 and the ground can be as close as possible, thereby extending the guiding and buffering distance for the plates.

[0061] As a preferred embodiment of the present invention, the support plate 23 has a smooth design on the side away from the deflection slot 5 and a rough design on the side close to the deflection slot 5;

[0062] By adjusting the smoothness of both sides of the support plate 23, on the one hand, when the support plate 23 moves downward with the plate, it is prevented from being separated from the plate. On the other hand, when the support plate 23 contacts the stacked plate during the downward movement, the support plate 23 rotates into the deflection groove 5. At this time, the smooth setting of the side of the support plate 23 away from the deflection groove 5 can reduce the friction between the support plate 23 and the plate.

[0063] As a preferred embodiment of the present invention, a friction ring 51 is detachably fixedly mounted on the adjustment block 31, and the friction ring 51 is sleeved on the outer side of the guide rod 21;

[0064] By installing the friction ring 51 on the adjustment block 31, and utilizing the friction ring 51 to be rotatably connected to the guide rod 21, during the adjustment process before material cutting, by replacing the friction ring 51 with different roughness, the friction force between the friction ring 51 and the guide rod 21 is different. When the plate is pressed on the support plate 23, the difficulty of rotating the guide rod 21 is different, thereby adjusting the efficiency of the rotation of the guide rod 21, and then adjusting the buffering effect when the plate descends.

[0065] As a preferred embodiment of the present invention, a push rod 6 is fixedly mounted on the tool holder 12, and the support plate 23 is located on the movement path of the push rod 6;

[0066] By setting the push rod 6, when the lift 1 drives the tool holder 12 to move downward, the push rod 6 pushes the support plate 23, causing the support plate 23 to drive the rotating belt 22 to move. When the plate is too light or the friction between the rotating belt 22 and the guide rod 21 is too large, the support plate 23 will not move downward in time. At this time, the push rod 6 pushes the support plate 23 when moving downward, causing the support plate 23 to move downward a certain distance. When the material is cut into plates, the plates fall onto the support plate 23, thereby avoiding obstruction to the subsequent loading of materials.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
