Description

Technical Field

[0001] The utility model relates to a shearing machine with an external guiding device to form an externally wrapped guiding structure, belonging to the field of shearing equipment. Background Art

[0002] A shearing machine is a commonly used shearing device. By the engagement of a moving knife moving downward and a fixed knife, materials can be cut off, and even directly cut into small pieces.

[0003] Common shearing machines include, for example, the stepped combined shearing edge with the Chinese patent publication number CN103692013A, the continuous edge vertical and horizontal composite shearing machine with the Chinese patent publication number CN103878433A, the hydraulic synchronous gantry shear with the Chinese patent publication number CN205362819U, the gantry type hydraulic scrap steel shearing machine with the Chinese patent publication number CN306342344S, the blade clearance adjustable gantry type shearing machine with the Chinese patent publication number CN114799312A, the detachable multi-edge shear and its gantry shear with the Chinese patent publication number CN214602228U, the vertical and horizontal gantry shear with the Chinese patent publication number CN216177119U, the sheet material shearing system and its serrated multi-knife shear with the Chinese patent publication number CN114012166A, the upper knife seat of a diamond shear and its diamond shear with the Chinese patent publication number CN219986385U, etc.

[0004] For existing gantry type shearing machines, in order to enable the moving knife assembly to move downward smoothly, vertical guiding devices (usually made of wear-resistant steel, with strong stability and reliability) are arranged on both sides of the moving knife seat, and the guiding devices are installed inside the gantry; however, since the guiding devices are arranged inside the gantry, generally groove-shaped guiding grooves are set. During the process of cutting materials, some small material particles are likely to splash during shearing, and thus there is a certain probability of entering the guiding grooves; as the moving knife assembly moves downward, the material particles are extremely easy to be stuck in the guiding devices, and the material particles move along with the guiding devices. Over time, it is easy to cause abnormal wear of the guiding devices; when the guiding devices are severely worn, often only the whole set of guiding devices can be replaced by stopping the machine; the replacement process requires removing the entire moving knife assembly, which is time-consuming and laborious, and after replacement, the guiding devices also need to be adjusted for a long time to ensure high-precision vertical guiding.

[0005] Therefore, the existing guiding devices have the risk of accidental damage, which reduces the service life of the equipment and increases the use and maintenance costs of the equipment.

[0006] In view of the above deficiencies, it is necessary to improve the vertical guiding device of the gantry type shearing machine. Summary of the Utility Model

[0007] The purpose of the present utility model is to provide a guiding outer - wrapped shearing machine. When the vertical guiding device moves outwards and is arranged on the outer sides of both sides of the equipment frame, a guiding outer - wrapped shearing machine is formed. During operation, the guiding device is on the outer side and is not easily affected by the sheared materials, thus reducing the risk of accidental damage to the guiding device.

[0008] To achieve the above - mentioned utility model purpose, the present utility model provides a guiding outer - wrapped shearing machine, which includes a frame, a fixed knife seat, a moving knife seat, a shearing oil cylinder, and a vertical guiding device;

[0009] The frame is a gantry frame, and the fixed knife seat is below. The shearing working part of the fixed knife seat is provided with a replaceable lower shearing blade;

[0010] The upper part of the frame is provided with a vertically liftable moving knife seat, and the moving knife seat is located on the discharge side of the fixed knife seat;

[0011] The shearing working part of the moving knife seat is provided with a replaceable upper shearing blade that matches the lower shearing blade on the fixed knife seat;

[0012] The top of the frame is provided with a shearing oil cylinder. The cylinder body of the shearing oil cylinder is vertically fixed on the top of the frame, and the shearing piston rod of the shearing oil cylinder extends downward and is connected to the top of the moving knife seat;

[0013] A vertical guiding device is arranged between the frame and the moving knife seat, and vertical guiding devices are arranged on both sides of the moving knife seat;

[0014] The guiding device is located on the outer side of the frame.

[0015] As a further improvement of the present utility model, vertical guiding grooves are arranged on the outer sides of both sides of the frame;

[0016] The transverse two sides of the moving knife seat extend outwards to form guiding parts, and the guiding parts wrap the guiding grooves of the frame from the outside;

[0017] The inner side of the guiding part is provided with guiding blocks that match the guiding grooves.

[0018] Further, the guiding groove is a V - shaped groove, and the guiding block is a V - shaped block.

[0019] Further, a guiding lining plate is arranged at the contact part of the guiding groove and the guiding block.

[0020] Still further, a guiding lining plate is arranged on the guiding surface of the guiding groove;

[0021] A guiding lining plate is arranged on the guiding surface of the guiding block.

[0022] As a further improvement of the present utility model, the upper shearing blade is inclined along the vertical direction.

[0023] As a further improvement of the present utility model, the upper part of the frame is provided with a vertically liftable pressing head;

[0024] The pressure head is located directly above the fixed knife seat;

[0025] The shape of the side of the pressure head close to the moving knife seat is consistent with the shape of the shearing working part of the fixed knife seat;

[0026] The pressure head cooperates with the moving knife seat to clamp the material located at the shearing working part;

[0027] A pressure oil cylinder is provided at the top of the frame. The cylinder body of the pressure oil cylinder is vertically fixed at the top of the frame, and the pressure piston rod of the pressure oil cylinder extends downward and is connected to the top of the pressure head.

[0028] For the guiding outer - wrapped shearing machine of the present utility model, the vertical guiding devices on both sides are moved to the outside. In particular, the guiding grooves are far away from the shearing working part, thus avoiding the accidental jamming of the splashing materials generated during shearing into the guiding grooves, resulting in accidental wear of the guiding devices, thereby improving the use reliability and stability of the shearing machine and extending its service life. At the same time, since the guiding devices are arranged outside the frame, when maintaining and replacing spare parts such as guiding liners, the line of sight is better, so the adjustment process is more convenient and fast.

[0036] The following further elaborates on the specific embodiments of the present utility model with reference to the drawings.

[0037] The guiding outer - wrapped shearing machine of the utility model, like the existing gantry shearing machine, also includes a frame 1, a fixed knife seat 2, a moving knife seat 3, a shearing oil cylinder 4, a pressing head 5, a pressing oil cylinder 6, and vertical guiding devices (7, 8). For details, reference can be made to Figures 1 - 3 .

[0038] In this embodiment, a serrated / rhombic multi - knife shear is taken as an example. The frame 1 of the guiding outer - wrapped shearing machine is a gantry. Below is the fixed knife seat 2. The shearing working part of the fixed knife seat 2 is designed according to the structure of the specific shearing machine, and is provided with replaceable lower shearing blades 21. In this embodiment, there are several lower shearing blades 21, which are arranged end - to - end in a serrated shape.

[0039] At the upper part of the frame 1, there is a vertically liftable moving knife seat 3. The moving knife seat 3 is located on the discharge side of the fixed knife seat 2. The shearing working part of the moving knife seat 3 is provided with replaceable upper shearing blades 31 that match the lower shearing blades 21 on the fixed knife seat 2. According to the shearing requirement, the upper shearing blades 31 are generally designed to be inclined in the vertical direction. In this way, it can not only reduce the shearing force (or increase the shearing pressure at the shearing contact part), but also push the material to be sheared outside the fixed knife seat 2 towards the shearing part to achieve reliable shearing. At the same time, it can also generate a thrust away from the fixed knife seat 2 on the moving knife seat 3, avoiding the collision between the upper shearing blades 31 and the lower shearing blades 21 and causing blade damage.

[0040] At the upper part of the frame 1, there is also a vertically liftable pressing head 5. The pressing head 5 is located directly above the fixed knife seat 2. Generally, the shape of the side of the pressing head 5 close to the moving knife seat 3 is consistent with the shape of the shearing working part of the fixed knife seat 2, especially the overall shape of the lower shearing blades 21. Thus, the pressing head 5 can stably and reliably press the material on the moving knife seat 3, and the material located at the shearing working part is reliably clamped from above and below, avoiding the loosening of the material during shearing and affecting the reliability of shearing and avoiding equipment damage.

[0041] At the top of the frame 1, there are 2 groups of driving devices, namely the shearing oil cylinder 4 and the pressing oil cylinder 6 respectively. Among them, the shearing oil cylinder 4 has a larger cylinder diameter and generates a larger pressure; while the pressing oil cylinder 6 has a relatively smaller cylinder diameter and generates a relatively smaller pressure. The cylinder body of the shearing oil cylinder 4 is vertically fixed at the top of the frame 1, and the shearing piston rod 41 of the shearing oil cylinder 4 extends downward and is connected to the top of the moving knife seat 3. Similarly, the cylinder body of the pressing oil cylinder 6 is vertically fixed at the top of the frame 1, and the pressing piston rod 61 of the pressing oil cylinder 6 extends downward and is connected to the top of the pressing head 5.

[0042] Preferably, there are vertical guiding devices between the frame 1 and the moving knife seat 3, and preferably, vertical guiding devices are provided on both sides of the moving knife seat 3, so as to ensure that the moving knife seat 3 can move vertically downward stably and reliably during the shearing process for shearing.

[0043] The improvement of the guiding outer wrapping type shearing machine of the present utility model lies in that, as Figures 1 - 7 shown, the guiding device is located outside the frame 1; specifically, vertical guiding grooves 7 are provided on the outer sides of both sides of the frame 1, and as Figure 5 shown, the lateral sides of the moving knife seat 3 extend outwards to form guiding parts, and the guiding parts wrap the guiding grooves 7 of the frame 1 from the outside and form guiding blocks 8 that match the guiding grooves 7. Preferably, the guiding groove 7 is a V-shaped groove, and the guiding block 8 is a V-shaped block, so that horizontal limiting can also be formed to prevent the moving knife seat 3 from generating excessive displacement in the horizontal direction during operation.

[0044] Both the guiding groove 7 and the guiding block 8 are provided with wear-resistant and adjustable guiding liners, which are convenient for replacement and can also achieve clearance adjustment to ensure reliable vertical guiding between the frame 1 and the moving knife seat 3. For details, reference can be made to the guiding device of the upper knife seat of the slider type shearing machine with the Chinese patent publication number CN101856746A.

[0045] For the guiding outer wrapping type shearing machine of the present utility model, the vertical guiding devices on both sides are moved to the outside, especially making the guiding groove 7 away from the shearing working part, so as to avoid the splashed materials generated during the shearing process from accidentally getting stuck in the guiding groove 7, resulting in accidental wear of the guiding device.

[0046] The preferred embodiments of the present utility model have been specifically described above, but the present utility model is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
