Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate shearing, more particularly, it relates to a steel plate shearing device. BACKGROUND

[0002] In the field of steel processing, steel plate shearing machines, as key equipment, undertake the important task of accurately cutting steel plates according to preset dimensions, and their performance and efficiency directly affect the operation of the entire steel processing production line. The plate shearing and blanking device of the steel plate shearing machine, as an important part of the plate shearing machine, is mainly responsible for transferring the cut plates from the shearing area and stacking them reasonably for subsequent processing or transportation operations.

[0003] At present, in the actual application scene of many steel plate shearing machines on the market, there are still prominent technical defects in the plate shearing and blanking link. Specifically, the cut plates are mainly processed by manual unloading, and the operator needs to manually carry the plates from the shearing position to the material moving trolley. Due to the randomness of manual operation, the stacking of plates on the material moving trolley is often chaotic and lacks effective arrangement and planning. This chaotic stacking state makes the plates easily collide with other equipment in the factory during the movement of the material moving trolley, resulting in scratches, dents and other damage on the surface of the plates, which seriously affects the quality of the plates and subsequent processing and use, reduces the product qualification rate, and causes economic losses to the enterprise.

[0004] On the other hand, in order to reduce the risk of collision between the plates and the equipment, some operators will try to stack the plates neatly on the material moving trolley. However, manual stacking cannot accurately control the position and height of each layer of plates, and as the plates are continuously stacked, the overall height gradually increases, and the friction between the layers of plates also significantly increases. When unloading is needed, the excessive friction makes it difficult to separate and remove the plates, making the unloading process difficult, consuming a lot of time and manpower, and possibly causing secondary damage to the plates due to forced unloading, further affecting production efficiency and product quality.

DETAILED DESCRIPTION

[0023] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] It should be noted that all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs, unless otherwise specified.

[0025] Referring to Figures 1-9 The present application provides the following technical solutions: In order to solve the problem that the cut-off plate 11 is mainly unloaded by manual and randomly stacked on the material moving trolley 3, resulting in messy stacking and easy collision with the equipment to cause damage to the plate 11; or the plate 11 is too high due to manual stacking, the interlayer friction is increased, and the unloading is difficult.

[0026] The plate shearing machine includes a machine shell 1 and a plate shearing device 2 arranged on the top of the machine shell 1. The plate shearing machine further includes a material moving trolley 3 and an interlaced unloading mechanism 4. The material moving trolley 3 is placed beside the plate shearing device 2 and is used to carry the cut-off plate 11. The interlaced unloading mechanism 4 is arranged beside the machine shell 1 and is used to interlacedly stack the cut-off plate 11. The interlaced unloading mechanism 4 includes a guide portion 41 and a guide abutting portion 42. The guide portion 41 has a pair of guide portions 41 arranged on the two sides of the machine shell 1 respectively, and the pair of guide portions 41 are located on the two sides of the material moving trolley 3. The guide abutting portion 42 has a pair of guide abutting portions 42 slidingly arranged on the two sides of the machine shell 1 respectively, and the pair of guide abutting portions 42 are gap-fitted with the guide portion 41. The pair of guide abutting portions 42 are used to abut the two sides of the cut-off plate 11 after unloading and make the cut-off plate 11 in an interlaced stacking state.

[0027] Firstly, the plate shearing device 2 cuts the plate 11, and the cut-off plate 11 is placed on the material moving trolley 3 by the operator. In order to realize the interlaced stacking of the plate 11 on the trolley, in the present embodiment, when the plate 11 falls onto the material moving trolley 3, one of the guide abutting portions 42 starts to act, and moves to one side of the plate 11 and abuts the plate 11, so as to push the plate 11 to move horizontally. When the next plate 11 falls down, the guide abutting portion 42 is retracted, and the guide abutting portion 42 on the other side starts to act, and pushes the newly fallen plate 11 to move in the opposite direction, so that the plate 11 above is staggered with the plate 11 placed before in the horizontal direction by a certain distance. Through the alternate action of the guide abutting portions 42 on the two sides, each newly fallen plate 11 is arranged in a left-right staggered state with the previous plate 11. The interlaced stacking mode avoids the increase of interlayer friction and the difficulty of unloading caused by the over-high stacking of the plate 11, and prevents the collision with the surrounding equipment in the moving process due to the messy stacking, so as to effectively protect the surface quality of the plate 11 and improve the efficiency and convenience of the subsequent unloading operation.

[0028] Referring to Figures 1-3, the staggered blanking mechanism 4 further comprises a first telescopic cylinder 43; the end faces of the pair of guiding abutting portions 42 are cuboid structures, and the outer sides of the pair of guiding abutting portions 42 are chamfered structures; when the pair of guiding abutting portions 42 moves, the guiding portions 41 in gap fit can be in a moving state close to the material moving trolley 3; the first telescopic cylinder 43 has a pair of and is arranged on the sides of the machine shell 1 respectively, and the pair of first telescopic cylinders 43 are located on the two sides of the material moving trolley 3, and the output ends of the pair of first telescopic cylinders 43 are connected with the pair of guiding abutting portions 42 respectively; when the first telescopic cylinder 43 is started, the guiding abutting portions 42 can be driven to be in a moving state close to the material moving trolley 3.

[0029] Specifically, in the embodiment, the guiding abutting portions 42 and the guiding portions 41 adopt a gap fit mode, and the guiding portions 41 provide guidance and stable support for the movement of the guiding abutting portions 42. When the first telescopic cylinder 43 is started, the output end of the first telescopic cylinder 43 pushes the guiding abutting portions 42 to move stably along the guiding portions 41, so that the guiding abutting portions 42 can move close to the material moving trolley 3 in a stable posture trajectory, until the guiding abutting portions 42 abut against the plate 11, thereby realizing accurate control of the position of the plate 11 and staggered stacking.

[0030] In the embodiment, in order to solve the problem that the position of the trolley is unstable after moving and it is difficult to reliably load the blanking plate 11.

[0031] Referring to Figure 7 The staggered blanking mechanism 4 further comprises a connecting portion 44, a mounting portion 45 and a bolt 46; the connecting portion 44 has a pair of and is arranged on the top of the material moving trolley 3 respectively, and the pair of connecting portions 44 are located on the sides of the machine shell 1 and below the plate shearing device 2; the mounting portion 45 has a pair of and is arranged on the sides of the machine shell 1 respectively, and the pair of mounting portions 45 are located above the connecting portions 44; the bolt 46 is slidingly arranged on the top of the pair of mounting portions 45; when the material moving trolley 3 and the connecting portion 44 move to below the mounting portion 45, the bolt 46 is in a sliding state and connected with the connecting portion 44.

[0032] Specifically, when the material moving trolley 3 is pushed to below the mounting portion 45 on the side of the machine shell 1, the operator first aligns the connecting portion 44 on one side of the trolley with the corresponding mounting portion 45, and realizes preliminary fixation by inserting the bolt 46. Then, the trolley is slightly pushed to adjust the position, so that the other connecting portion 44 is also accurately aligned with the corresponding mounting portion 45, and the second bolt 46 is inserted to complete the bilateral fastening. Through the cooperation of the bolt 46, the connecting portion 44 and the mounting portion 45, the rapid positioning and reliable connection of the material moving trolley 3 are realized, which not only effectively enhances the overall stability of the trolley during the blanking process, but also significantly reduces the time required for repeated position adjustment.

[0033] In order to solve the problem that the guiding abutting portion 42 is difficult to effectively push the plate 11 to realize staggered stacking due to the random position of the plate 11 placed by the operator.

[0034] Referring to Figure 8 , the staggered blanking mechanism 4 further comprises a first transverse guide rail 47, a first transverse sliding table 48 and a fixed portion 49; the first transverse guide rail 47 has a pair of and is respectively slidably arranged on the two sides of the machine shell 1, and a pair of first transverse guide rails 47 are located on the two sides of the blanking position of the plate shearing device 2; the first transverse sliding table 48 has a pair of and is respectively slidably arranged on the pair of first transverse guide rails 47; the fixed portion 49 has a pair of and is respectively arranged on the end face of the pair of first transverse sliding tables 48, and a pair of fixed portions 49 are used for installing the first telescopic cylinder 43 and the guiding portion 41.

[0035] Specifically, when the plate 11 is placed on the material moving trolley 3 and is in an inclined state, the system can respectively control the two first transverse sliding tables 48 to drive the corresponding side guiding abutting portion 42 to move horizontally along the blanking direction, so as to adjust the transverse position thereof. At the same time, by independently controlling the extension and retraction actions of the two first telescopic cylinders 43, the guiding abutting portion 42 is driven to abut against the corresponding position of the inclined end of the plate 11, respectively, so as to gradually correct and flatten the plate 11, and finally make the plate 11 in a regular state under the cooperation of the pair of guiding abutting portions 42, thereby providing a guarantee for the subsequent continuous realization of staggered stacking. In the embodiment, the first transverse guide rail 47 and the first transverse sliding table 48 are driven by a linear motor, and the first transverse guide rail 47 and the first transverse sliding table 48 constitute a linear module, which is a common existing structure of linear motor driving.

[0036] Referring to Figure 8 , the staggered blanking mechanism 4 further comprises a vertical guide rail 491 and a vertical sliding table 492; the vertical guide rail 491 has a pair of and is respectively arranged on the two sides of the machine shell 1; the vertical sliding table 492 has a pair of and is respectively slidably arranged on the pair of vertical guide rails 491, and the end faces of the pair of vertical sliding tables 492 are fixedly connected with the end faces of the pair of first transverse guide rails 47, so that when the vertical sliding table 492 moves, the first transverse guide rail 47 can be driven to be in a synchronous movement state.

[0037] Specifically, in order to make a pair of guide abutting portions 42 push each plate 11 according to the thickness of the stacked plate 11 to achieve the staggered stacking effect of the plate 11. After the guide abutting portion 42 pushes the plate 11 and the lower plate 11 to form a staggered stacking, the vertical guide rail 491 drives the vertical sliding table 492 to move, which can drive the first horizontal guide rail 47, the fixed portion 49, the first telescopic cylinder 43 and the guide abutting portion 42 to move synchronously, thereby adjusting the vertical distance of the guide abutting portion, facilitating the guide abutting portion 42 to rise and prepare for the next abutting of the plate 11. And in this embodiment, the vertical guide rail 491 and the vertical sliding table are driven by a linear motor, and the vertical guide rail 491 and the vertical sliding table 492 form a linear module, which is a common existing structure of linear motor drive.

[0038] Referring to Figures 1-4 , the staggered blanking mechanism 4 further comprises a limiting plate 493; the limiting plate 493 is provided on the top of the material moving trolley 3, and a plurality of limiting plates 493 are arranged at intervals, and the plurality of limiting plates 493 are used to limit the blanking position of the cut plate 11.

[0039] Specifically, in order to prevent the plate 11 from falling out of the material moving trolley. The plate 11 can be in abutting state with the limiting plate 493 when falling, and the plurality of limiting plates 493 are cuboid structures, and the contact surfaces of the plurality of limiting plates 493 and the plate 11 are provided with rubber pads, which can prevent the plate 11 from falling out of the moving trolley, and also reduce the hard contact between the plate 11 and the limiting plate 493 to prevent damage to the plate 11 and the limiting plate 493.

[0040] Referring to Figures 2-5 , the staggered blanking mechanism 4 further comprises a hydraulic cylinder 494 and a pushing portion 495; the hydraulic cylinder 494 is arranged beside the cabinet 1, and the hydraulic cylinder 494 is located below the blanking position of the cut plate 11; the pushing portion 495 is arranged at the output end of the hydraulic cylinder 494, and the pushing portion 495 is located above the material moving trolley 3, which can drive the pushing portion 495 to move when the hydraulic cylinder 494 is started.

[0041] Specifically, in order to make the orderly staggered stacking between the plurality of plates 11. When the guide abutting portion 42 makes the plates 11 form staggered stacking, the hydraulic cylinder 494 is started immediately to drive the pushing portion 495 to move horizontally. In this process, the pushing portion 495 can be matched with a pair of guide abutting portions 42 respectively, so that the plates 11 are in a regular arrangement state. The pushing portion 495 gradually abuts against the plates 11 and applies a pushing force, and pushes the whole stack of plates 11 to move towards the limiting plate 493 until the plates 11 are in close contact with the limiting plate 493 and then stop. The gap and misalignment between the plates 11 are effectively eliminated, and it is ensured that each layer of plates 11 always maintains a neat and stable staggered arrangement state during the blanking and stacking process, thereby improving the overall integrity of the stack and the convenience of subsequent transfer.

[0042] Referring to Figure 5 , the bottom surface of the pushing portion 495 is parallel to the upper surface of the material moving trolley 3, and the pushing portion 495 can move in the horizontal direction under the drive of the hydraulic cylinder 494, and the pushing portion 495 is used to push the blanked plates 11 to be aligned.

[0043] Specifically, after the blanked plates 11 are stacked on the material moving trolley 3, the hydraulic cylinder 494 drives the pushing portion 495 to move in the horizontal direction, and the end surface of the pushing portion 495 can push the plates 11 with the bottom surface parallel to the surface of the trolley, so that the plates 11 are neatly aligned towards the limiting plate 493, and the quick regularity is realized.

[0044] Referring to Figure 6 , the gap width between the end surface contact surfaces of the guide portion 41 and the guide abutting portion 42 is adjustable, and the guide abutting portion 42 is used to contact the end surface of the blanked plates 11 and drive the plates 11 to be in a moving state.

[0045] Specifically, the gap width between the end surfaces of the guide portion 41 and the guide abutting portion 42 is adjusted by the first telescopic cylinder 43, which can adapt to the guiding needs of plates 11 of different thicknesses and stably push the plates 11 to move transversely, thereby realizing precise staggered stacking.

[0046] Referring to Figure 7 , the top of each of the pair of connecting portions 44 is provided with a circular hole for sliding of the pin 46.

[0047] Specifically, the circular hole provided at the top of the connecting portion 44 provides a sliding channel for the pin 46, and when the material moving trolley 3 moves to below the mounting portion 45, the pin 46 is smoothly inserted and passes through the circular hole to realize quick positioning and connection.

[0048] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor should belong to the protection scope of the present application.
