Description

Technical Field

[0001] This utility model relates to the field of metal product manufacturing, and in particular to a metal sheet production equipment. Background Technology

[0002] Existing sheet metal production equipment uses a moving upper blade and a fixed lower blade with a suitable blade gap to apply shearing force to metal sheets of various thicknesses, causing the metal billet to break and separate to the required dimensions. However, when cutting the metal billet, the blades move from top to bottom, causing the cut edge of the metal billet to bend due to the pressure of the blades. This results in uneven cut edges on the finished sheet metal, affecting its usability. Therefore, there is an urgent need for sheet metal production equipment that can apply equal shearing force to both sides of the metal billet. Utility Model Content

[0003] The purpose of this utility model is to provide a metal sheet production equipment to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] Metal sheet production equipment, including:

[0006] frame;

[0007] A transmission component, which is mounted on the rack;

[0008] A shearing assembly is mounted on the frame and located at the output end of the transmission assembly. The shearing assembly includes an upper mounting plate, a lower mounting plate, and a driving member. The lower mounting plate is located directly below the upper mounting plate. The driving member is used to drive the upper mounting plate and the lower mounting plate to move towards each other or away from each other in the vertical direction of the frame. Each of the upper mounting plate and the lower mounting plate has a cutter on its side that is close to each other, and a shearing gap is formed between the cutter on the upper mounting plate and the cutter on the lower mounting plate.

[0009] This technical solution has at least the following beneficial effects: After the metal billet to be sheared is placed on the conveying assembly and the shearing assembly is started, the metal billet moves through the conveying assembly to the shearing gap. Under the action of the driving component, the upper mounting plate and the lower mounting plate move simultaneously toward each other, so that the cutters on both sides of the shearing gap cut into the metal billet synchronously. At this time, the metal billet is subjected to shearing forces of the same magnitude but opposite directions on both sides. The two shearing forces cancel each other out, so that the metal billet is only cut off instead of being squeezed by the blades and bent, thereby improving the flatness of the cut metal sheet edge and improving the use effect of the metal sheet.

[0010] As a further improvement to the above technical solution, the upper mounting plate is provided with a first connecting plate, the end of the first connecting plate away from the upper mounting plate being a first free end, which extends downwards. The lower mounting plate is provided with a second connecting plate, the end of the second connecting plate away from the lower mounting plate being a second free end, which extends upwards. During shearing, the upper mounting plate drives the first connecting plate to move synchronously, and the lower connecting plate drives the second connecting plate to move synchronously, so that the first free end and the second free end abut against the metal billet transmitted to the shearing gap from the upper and lower sides, forming a stable clamping of the metal billet and reducing the stress-induced torsional deformation of the metal billet.

[0011] As a further improvement to the above technical solution, both the first free end and the second free end are provided with elastic strips. These elastic strips increase the friction between the first and second free ends and the metal billet placed within the shearing gap, thereby reducing the movement of the metal billet within the shearing gap and improving the effectiveness of the shearing assembly. Simultaneously, the elastic deformation of the elastic strips allows the cutters located on the upper and lower sides of the shearing gap to press more firmly against the metal billet surface after contacting it. Compared to the first free end directly and rigidly contacting the metal billet, this provides more travel distance for the cutters at each location, reducing the impact of each free end on the movement of each cutter.

[0012] As a further improvement to the above technical solution, the projections of the elastic strips at the first and second free ends onto the vertical plane are both located within the projection of the shearing gap onto the same vertical plane. This design ensures that both elastic strips are positioned between the two cutters. After the first and second mounting plates move, the two elastic strips first abut against the metal blank to be sheared, thereby positioning the metal blank. Then, the driving component drives the first and second mounting plates to continue moving closer to each other, causing the two cutters to begin cutting the metal blank. At this point, the two elastic strips effectively fix the metal blank, allowing the cutters to stably shear it.

[0013] As a further improvement to the above technical solution, the first free end is located directly above the second free end. When the first free end and the second free end are directly opposite each other, and the first free end and the second free end move, they can press the metal billet on the same vertical axis, thereby achieving stable clamping of the metal billet. At the same time, the two directly opposite ends can cancel each other out the force on the metal billet, reducing the bending deformation of the metal billet under the pressure of the first free end and the second free end.

[0014] As a further improvement to the above technical solution, both the first free end and the second free end are located on the side of the shearing assembly away from the transmission assembly. The first and second free ends clamp and fix the uncut metal billet on one side, while the transmission assembly fixes the uncut metal billet on the other side. This allows the metal billet to be clamped before being sheared, and also allows for clamping of the sheared portion, reducing the bending of the sheared metal sheet.

[0015] As a further improvement to the above technical solution, the conveying assembly includes conveying rollers, and multiple conveying rollers are arranged in a front-to-back direction on the frame, with all of the conveying rollers rotating on the frame. The rotation of the conveying rollers stably conveys the metal billet to the shearing assembly.

[0016] As a further improvement to the above technical solution, the transmission assembly further includes a moving frame and pressing rollers. The moving frame has multiple pressing rollers arranged at intervals along its front-to-back direction, with the pressing rollers positioned above the transmission rollers. During the transport of the metal billet, the pressing rollers press the metal billet against the transmission rollers, working together with the first and second free ends to clamp the metal billet onto the frame.

[0017] As a further improvement to the above technical solution, the movable frame can move and be positioned within the frame in the vertical direction. During the transport of metal billets, the movable frame moves towards or away from the conveyor rollers, causing the pressing rollers to move synchronously, changing the distance between the conveyor rollers and the pressing rollers. This allows the production equipment to confine the metal billets within the conveyor assembly while accommodating metal billets of different sizes, thus improving the practicality of the production equipment.

[0018] As a further improvement to the above technical solution, the frame is provided with multiple pairs of limiting rollers arranged along the front-to-back direction. Two limiting rollers from the same pair are respectively installed on both sides of the frame along the left-to-right direction. The two limiting rollers in the same pair can move towards or away from each other in the left-to-right direction. After the limiting rollers move, they restrict the movement of the metal billet on both sides, cooperating with the transmission assembly to simultaneously position the metal billet from the top-to-bottom and left-to-right directions, improving the stability of the metal billet's movement within the production equipment.

[0028] In existing metal sheet production equipment, a certain length of sheet is cut from a whole piece of metal billet by shearing. This typically involves a moving upper blade and a fixed lower blade. When the metal billet is placed between the upper and lower blades, the upper blade exerts a downward shearing force on the billet. While shearing the billet, the side of the cut metal sheet that is close to the billet experiences pressure bending, resulting in uneven cuts on the final metal sheet and affecting its usability. Therefore, this application provides a metal sheet production device that can provide shearing forces from both sides of the metal billet, allowing the two shearing forces to cancel each other out and reducing bending in the final cut metal sheet.

[0029] Reference Figure 1 and Figure 2 This application provides a metal sheet production equipment, which includes:

[0030] Rack 1;

[0031] Transmission component 2, which is mounted on rack 1;

[0032] The shearing assembly 3 is mounted on the frame 1 and is located at the output end of the transmission assembly 2. The shearing assembly 3 includes an upper mounting plate 31, a lower mounting plate 32, and a driving member 34. The lower mounting plate 32 is located directly below the upper mounting plate 31. The driving member 34 is used to drive the upper mounting plate 31 and the lower mounting plate 32 to move in the vertical direction in a direction that approaches or moves away from each other. A cutter 33 is provided on the side of the upper mounting plate 31 and the lower mounting plate 32 that approaches each other, and a shearing gap is formed between the cutter 33 of the upper mounting plate 31 and the cutter 33 of the lower mounting plate 32.

[0033] The technical solution has at least the following beneficial effects: After the metal billet to be sheared is placed on the transmission component 2 and the shearing component 3 is started, the metal billet moves to the shearing gap through the transmission component 2. Under the action of the drive component 34, the upper mounting plate 31 and the lower mounting plate 32 move towards each other at the same time, so that the cutters 33 on both sides of the shearing gap cut into the metal billet synchronously. At this time, the metal billet is subjected to shearing forces of the same magnitude but opposite directions on both sides. The two shearing forces cancel each other out, so that the metal billet is only cut off instead of being squeezed by the blades and bent, thereby improving the flatness of the cut metal sheet edge and improving the use effect of the metal sheet.

[0034] Specifically, in this embodiment, the driving component 34 includes a bidirectional lead screw 341 and a drive motor. The bidirectional lead screw 341 is rotatably mounted on the frame 1 and extends vertically. The upper mounting plate 31 and the lower mounting plate 32 are respectively threaded to two opposite threaded sections of the bidirectional lead screw 341. The drive motor is fixedly mounted on the frame 1, and the bidirectional lead screw 341 is fixedly connected to the output end of the drive motor. By starting the drive motor, the bidirectional lead screw 341 is rotated, thereby driving the upper mounting plate 31 and the lower mounting plate 32 to move synchronously toward each other or away from each other.

[0035] Furthermore, the frame 1 is provided with driving components 34 on both sides along the left and right directions. The two driving components 34 are respectively connected to the two ends of the upper mounting plate 31 and the lower mounting plate 32 along the left and right directions. The two driving components 34 drive the upper mounting plate 31 and the lower mounting plate 32, thereby improving the stability of the movement of the upper mounting plate 31 and the lower mounting plate 32.

[0036] In other embodiments, the drive component 34 includes a drive cylinder. A corresponding drive cylinder is provided at both the upper mounting plate 31 and the lower mounting plate 32. The drive cylinder is installed in the frame 1. The upper mounting plate 31 is fixedly connected to the drive end of the corresponding drive cylinder, and the lower mounting plate 32 is fixedly connected to the drive end of the corresponding drive cylinder, so that the two blades can move toward each other or away from each other.

[0037] In this embodiment, the transmission assembly 2 includes transmission rollers 21. Multiple transmission rollers 21 are arranged at intervals along the front-to-back direction on the frame 1. The axes of the multiple transmission rollers 21 are parallel to the straight line in the left-to-right direction. Each transmission roller 21 is fitted with a connecting gear, and the connecting gears on the multiple transmission rollers 21 are fitted with the same transmission chain. A transmission motor is fixedly mounted on the frame 1. One transmission roller 21 is fixedly connected to the output shaft of the transmission motor. This transmission roller 21 connected to the transmission motor drives the remaining transmission rollers 21 to rotate on the frame 1 via the transmission chain. After the metal billet is placed on the surface of the transmission roller 21, starting the transmission motor will move the metal billet on the frame 1.

[0038] In other embodiments, the transmission component 2 can be a push cylinder and a push plate. The push cylinder is fixedly installed on the frame 1, and the output end of the push cylinder extends in the front-back direction. The push plate is installed on the output end of the push cylinder and extends in the left-right direction. After the metal billet is placed on the end of the push plate away from the push cylinder, the metal billet can be stably pushed to the shearing component 3.

[0039] When the metal billet moves on the transfer roller 21, in order to reduce the offset of the metal billet on the transfer roller 21 and improve the transfer stability, the transfer assembly 2 also includes a moving frame 23 and a pressing roller 24. The moving frame 23 is installed on the frame 1, and multiple pressing rollers 24 are arranged at intervals along the front-back direction. The length direction of each pressing roller 24 is parallel to the left-right direction. The pressing roller 24 is located above the transfer roller 21. When the metal billet is placed on the transfer roller 21 for transfer, the pressing roller 24 presses against the metal billet from above, increasing the pressure of the metal billet on the transfer roller 21 below, thereby increasing the friction between the two, so that the actively rotating transfer roller 21 can better transfer the metal billet.

[0040] To enable the sheet metal production equipment of this application to adapt to metal billets of different sizes, the movable frame 23 can move and be positioned in the vertical direction of the frame 1. During the transport of the metal billet, the movable frame 23 moves toward or away from the transfer roller 21, causing the pressing roller 24 to move synchronously, changing the distance between the transfer roller 21 and the pressing roller 24. This allows the production equipment to confine the metal billet within the transfer assembly 2 while adapting to metal billets of different sizes, thus improving the practicality of the production equipment.

[0041] Specifically, a lifting cylinder 25 is fixedly installed on the frame 1. The output end of the lifting cylinder 25 extends in the vertical direction. The movable frame 23 is connected to the output end of the lifting cylinder 25. Activating the lifting cylinder 25 can drive the movable frame 23 to move up and down on the frame 1.

[0042] To restrict the movement of the metal billet in the left and right directions, the frame 1 is provided with multiple pairs of limiting rollers 4 arranged at intervals along the front and back directions. The two limiting rollers 4 of the same pair are rotatably installed on both sides of the frame 1 in the left and right directions. The rotation axis of each limiting roller 4 extends in the up and down direction. The two limiting rollers 4 of the same pair can move and be positioned in the left and right directions toward each other or away from each other. After the limiting rollers 4 move, they restrict the two sides of the metal billet. In cooperation with the transmission component 2, the metal billet is positioned synchronously in the up and down and left and right directions, thereby improving the stability of the metal billet movement in the production equipment.

[0043] In this embodiment, multiple pairs of first mounting slots are arranged along the front-back direction on the frame 1. The two first mounting slots of the same pair are located on both sides of the frame 1 along the left-right direction. Each first mounting slot has a connecting block slidably installed in it. Each of the multiple connecting blocks is equipped with a limit roller 4. Each of the two connecting blocks of the same pair is provided with an elastic element. The end of the elastic element away from the connecting block is connected to the bottom of the first mounting slot along the left-right direction.

[0044] In other embodiments, multiple second mounting slots are arranged along the front-to-back direction inside the frame 1. Each of the multiple second mounting slots is equipped with a transverse lead screw. The transverse lead screw corresponds to each pair of limit rollers 4. The transverse lead screw extends in the left-to-right direction and has two threaded segments with different directions on both sides along its own length direction. The two threaded segments are threadedly connected to sliders. The top sidewall of the second mounting slot is provided with an upwardly extending mounting hole. Each slider extends upward out of the frame 1 through the mounting hole. The two limit rollers 4 of the same pair are respectively installed on the two sliders of the corresponding transverse lead screw. A transverse motor is provided on the frame 1. The transverse motor corresponds to each transverse lead screw. The output end of the transverse motor is connected to the corresponding transverse lead screw. Starting the transverse motor can drive the transverse lead screw to rotate forward or backward, so that the slider moves and drives the limit rollers 4 to move.

[0045] The upper mounting plate 31 is provided with a first connecting plate 5, the end of the first connecting plate away from the upper mounting plate 31 being a first free end 51, which extends downward. The lower mounting plate 32 is provided with a second connecting plate 6, the end of the second connecting plate 6 away from the lower mounting plate 32 being a second free end 61, which extends upward and is located directly below the first free end 51. Both the first free end 51 and the second free end 61 are provided with elastic strips 7.

[0046] First, the first free end 51 and the second free end 61, which are directly opposite each other, can clamp the metal billet, reducing the stress and torsional deformation of the metal billet. Second, through the elastic strip 7, both the first free end 51 and the second free end 61 can increase the friction force on the metal billet placed in the shearing gap, thereby reducing the movement of the metal billet in the shearing gap and improving the effect of the shearing assembly 3. At the same time, through the elastic deformation of the elastic strip 7, when the cutters 33 located on the upper and lower sides of the shearing gap continue to cut after contacting the surface of the metal billet, the elastic strip 7 can press more firmly against the surface of the metal billet. Compared with the first free end 51 and the second free end 61 directly and rigidly contacting the metal billet, it can provide the cutting 33 with a stroke at each point, reducing the influence of each free end on the movement of each cutting 33.

[0047] As a further preferred embodiment, the projections of the elastic strip 7 on the first free end 51 and the elastic strip 7 on the second free end 61 onto the vertical plane are both located within the projection of the shearing gap onto the same vertical plane. This arrangement ensures that both elastic strips 7 are located between the two cutters 33. After the first mounting plate and the second mounting plate move, the two elastic strips 7 first abut against the metal blank to be sheared, thereby positioning the metal blank. Then, the driving member 34 drives the first mounting plate and the second mounting plate to continue moving towards each other, causing the two cutters 33 to begin cutting the metal blank. At this time, the two elastic strips 7 achieve the fixation of the metal blank, and the cutters 33 can stably shear the metal blank.

[0048] As a further preferred embodiment, both the first free end 51 and the second free end 61 are located on the side of the shearing assembly 3 away from the transmission assembly 2. The first free end 51 and the second free end 61 clamp and fix the uncut metal billet on one side, while the transmission assembly 2 fixes the uncut metal billet on the other side. This allows the metal billet to be clamped before being sheared, and also allows for clamping of the sheared and separated portions, reducing the occurrence of bending in the sheared metal sheet.

[0049] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
