Description

Technical Field

[0001] The present application relates to the technical field of metal sheet processing equipment, and in particular to a lifting mechanism for a shearing machine. Background Art

[0002] A shearing machine is a machine for shearing plates. It includes a moving upper blade and a fixed lower blade. When in use, a reasonable blade gap is used to apply shearing force to metal plates of various thicknesses so that the plates are broken and separated according to the required size.

[0003] In the related art, the plates used in container manufacturing need to be pre-treated, and the main process flow of the pre-treatment is: loading and uncoiling, clamping and leveling, cut-to-length shearing (cutting the head and tail), automatic welding of the panels, sandblasting, roller coating, drying, etc. Among them, when the panels are automatically welded, because the welding part is the tail of the front roll leveling plate and the head of the rear roll leveling plate, the flatness of the joint of the plates is required to be high. Usually, a cut-to-length shearing machine is used in the previous process to remove the head and tail parts. The shearing machine includes a shearing machine body, a plurality of feed rollers located on one side of the shearing machine body, and a plurality of discharge rollers located on the other side of the shearing machine body. The plate is placed on the feed roller, and the feed roller rotates to convey the plate into the shearing machine body. The shearing machine body shears the plate to remove the head of the plate. When the sheared plate is conveyed to the discharge roller, the discharge roller flips so that the tail of the plate enters the shearing machine body. The shearing machine body cuts the tail of the plate, and then the discharge roller rotates forward to convey the cut plate to the next processing position.

[0004] With regard to the above-mentioned related technologies, the plates are relatively long and their own weight will cause the head and tail to bend downward. Since the height of the bent plates is lower than the front and rear positions of the shearing machine body, the forward or backward movement of the discharge roller will cause the bent plates to be unable to fit into the shearing machine. The plates can only be lifted up manually using tools and then moved onto the shearing machine, resulting in low work efficiency, high labor costs, and easy damage to the surface of the plates. Utility Model Content

[0005] In order to make it easier for the plate to enter the shearing machine body when the discharge roller moves forward or backward, the present application provides a lifting mechanism for the shearing machine.

[0006] The present application provides a lifting mechanism for a shearing machine, which adopts the following technical solution:

[0007] A lifting mechanism for a shearing machine comprises a shearing machine body, a lifting cylinder and a support plate, wherein a mounting plate is provided on one side of the shearing machine body, the lifting cylinder is fixedly connected to the mounting plate, the support plate is located on a side of the mounting plate away from the lifting cylinder and is used to support the plate, the piston rod of the lifting cylinder passes through the mounting plate and is fixedly connected to a side of the support plate close to the mounting plate, and the piston rod of the lifting cylinder and the support plate are arranged perpendicular to each other.

[0008] By adopting the above technical solution and setting the support plate of the lifting cylinder, the lifting cylinder can push the support plate to move so that the height of the support plate is greater than or equal to the feed port of the shearing machine body, and the downward bent part of the tail of the plate can be lifted, thereby facilitating the rear end of the plate to move back into the feed port of the shearing machine, thereby improving the process smoothness of the shearing machine body, increasing the overall production efficiency, and reducing damage to the surface of the plate and the labor intensity of employees.

[0009] Optionally, a guide column is fixedly connected to one side of the support plate close to the lifting cylinder, the guide column and the piston rod of the lifting cylinder are arranged parallel to each other, and the guide column passes through the mounting plate and extends to the outside of the side of the mounting plate away from the support plate.

[0010] By adopting the above technical solution and setting the guide column, the support plate can move along the length direction of the guide column, thereby avoiding the support plate from tilting and improving the stability of the support plate movement process.

[0011] Optionally, a side of the support plate away from the mounting plate is rotatably connected to a rotating roller.

[0012] By adopting the above technical solution and setting the rotating roller, the rotating roller can rotate so that the tail of the plate can be more easily inserted into the shearing machine body, and there is rotational friction between the plate and the rotating roller, which reduces the wear of the plate and increases the service life of the plate.

[0013] Optionally, two ears are fixedly connected to the side of the support plate away from the mounting plate, and the two ears are located at both ends of the support plate. A rotating shaft is rotatably connected to the rotating roller, and the rotating shaft and the rotating roller are coaxially arranged and both ends of the rotating shaft extend outside the rotating roller. A placement groove is provided on the side of the ear away from the support plate, which passes through two opposite side walls of the ear, and the two ends of the rotating shaft are respectively embedded in the two placement grooves in a one-to-one manner.

[0014] By adopting the above technical solution, the arrangement of the support ears and the placement groove enables the rotating shaft on the rotating roller to be placed in the placement groove. When the rotating roller is worn out after long-term use, the rotating roller can be taken out from the placement groove for replacement or maintenance, thereby improving the disassembly efficiency and service life of the rotating roller.

[0015] Optionally, bearings are sleeved on both ends of the rotating shaft, and the bearings are embedded in the placement grooves.

[0016] By adopting the above technical solution, the bearing is set so that the rotating roller and the rotating shaft can rotate relative to each other, and the rotating shaft can also rotate relative to the bearing, so that the rotating roller can rotate forward and reverse more flexibly under the drive of the plate, thereby improving the rotation efficiency of the rotating roller.

[0017] Optionally, a plurality of buffer blocks are fixedly connected to one side of the support plate close to the mounting plate.

[0018] By adopting the above technical solution and setting the buffer block, when the lifting cylinder pushes the support plate to move and reset, it can prevent the support plate from directly colliding with the mounting plate, thereby providing a buffer for the contact between the support plate and the mounting plate, reducing the wear of the support plate and the mounting plate, and increasing the service life of the support plate and the mounting plate.

[0019] Optionally, both ends of the mounting plate are slidably connected to the shearing machine body, a sliding frame is fixedly connected to the shearing machine body, a guide rod is fixedly connected to the sliding frame, a screw rod is passed through the sliding frame, the screw rod and the guide rod are arranged parallel to each other, one end of the screw rod extends outside the sliding frame, and a moving block that moves toward the shearing machine body is provided on the sliding frame, the moving block is sleeved and slidably connected to the screw rod and the guide rod, and the lifting cylinder is fixedly connected to the moving block on the side away from the mounting plate.

[0020] By adopting the above technical scheme, the sliding frame, the screw rod and the moving block are arranged, so that when the shearing machine body shears plates with different toughness, the screw rod is rotated to make the moving block move along the length direction of the screw rod, so that the lifting cylinder and the rotating roller on the moving block move toward the direction of the shearing machine body. The rotating roller can make the plates with greater flexibility closer to the feed port on the shearing machine body, thereby improving the movement efficiency and transmission efficiency of the rotating roller.

[0021] Optionally, one end of the screw rod extending outside the sliding frame is fixedly connected to a rotating handle.

[0022] By adopting the above technical solution and setting the rotating handle, the employee can hold the rotating handle to rotate it, thereby reducing the damage caused by the friction between the employee's hand and the thread on the screw rod, and improving the rotation efficiency of the screw rod.

[0023] Optionally, a pad is fixedly connected to a side of the shearing machine body away from the support plate.

[0024] By adopting the above technical solution, the setting of the pad makes the side of the shearing machine body away from the support plate have a support point, shortening the distance between the feed roller and the shearing machine body. When the feed roller conveys the plate into the shearing machine body to cut the head of the plate, it can enter the shearing machine body more easily.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The setting of the support plate of the lifting cylinder makes it easier for the tail of the plate to move back into the feeding port of the shearing machine, which improves the process fluency of the shearing machine, increases the overall production efficiency, and reduces the damage to the surface of the plate and the labor intensity of employees;

[0027] 2. The arrangement of the lugs and placement slots facilitates the removal of the rotating roller from the placement slot for replacement or maintenance, thereby improving the removal efficiency and service life of the rotating roller;

[0028] 3. The setting of the buffer block can provide a buffer for the contact between the support plate and the mounting plate when the support plate is reset, thereby reducing the wear of the support plate and the mounting plate and increasing the service life of the support plate and the mounting plate.

A plurality of discharge rollers 5 are installed on the side of the shearing machine body 1 away from the feed rollers 4, and the plurality of discharge rollers 5 are arranged in parallel to each other, so as to convey the plate with the head cut back into the shearing machine body 1 or convey the plate with the head and tail cut out of the shearing machine body 1. A pad 12 is fixedly connected to the side of the shearing machine body 1 close to the feed rollers 4, so as to facilitate the head of the plate to enter the feed port 11.

[0036] Combination Figure 2 The lifting assembly 2 includes a lifting cylinder 21, a support plate 22 and a rotating roller 23. A mounting plate 13 is installed on the side of the shearing machine body 1 close to the discharge roller 5. The mounting plate 13 is located below the feed port 11. The mounting plate 13 and the discharge roller 5 are arranged parallel to each other for installation of the lifting assembly 2. The lifting cylinder 21 is fixedly connected to the side of the mounting plate 13 away from the feed port 11. The support plate 22 is located on the side of the mounting plate 13 close to the feed port 11.

The sliding frame 31 is fixedly connected to the shearing machine body 1, and both ends of the guide rod 32 are fixedly connected to the sliding frame 31. The screw rod 33 is inserted into the sliding frame 31 and one end of the screw rod 33 extends outside the sliding frame 31. The screw rod 33 and the guide rod 32 are arranged parallel to each other. The moving block 34 is sleeved and slidably connected to the screw rod 33 and the guide rod 32. Rotating the screw rod 33 enables the moving block 34 to move toward the feed port 11. The side of the lifting cylinder 21 away from the mounting plate 13 is fixedly connected to the moving block 34, so that the moving block 34 can drive the lifting cylinder 21 to move synchronously. In the embodiment of the present application, the screw rod 33 and the rotating roller 23 are arranged perpendicular to each other. The end of the screw rod 33 extending outside the sliding frame 31 is fixedly connected to a rotating handle 331, so that the staff can rotate the screw rod 33 conveniently.

[0041] The implementation principle of a lifting mechanism for a shearing machine in an embodiment of the present application is as follows: a plate is located on a feed roller 4, which rotates so that the head of the plate enters the shearing machine body 1, and after the head of the plate is cut, it leaves the feed port 11 and moves to the discharge roller 5, and then the lifting cylinder 21 works to lift the rotating roller 23 on the support plate 22 to a level slightly higher than the feed port 11, and then the discharge roller 5 reverses, and the tail of the plate is synchronously lifted up with the rotating roller 23 and moves toward the feed port 11, and then the tail of the plate enters the feed port 11 for cutting, and after cutting is completed, the discharge roller 5 rotates forward to transport the cut plate; when the plate to be cut has a greater flexibility, the rotating handle 331 is rotated to move the movable plate and the lifting assembly 2 toward the feed port 11, so that the tail of the plate enters the feed port 11.
