Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, in particular to a bending machine used for steel plate processing. Background Art

[0002] In more and more steel mills, steel plates often need to be bent. The commonly used equipment is a bending machine, which usually consists of a machine base, a mold and a forming knife. At present, when workers bend steel plates, they hold the steel plates by hand, then push the steel plates into the machine base from the feed port, and the forming knife moves vertically downward, and the steel plates are bent through the mold to complete the bending process. The traditional manual holding causes the steel plates to warp when being bent by the forming knife, and even the two sides away from the forming knife shake, which makes it impossible to ensure that the steel plates are stably bent.

[0003] In the prior art, a Chinese patent document with a publication number of CN213968425U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a precision bending machine for steel plate processing, belonging to the technical field of bending machines, which includes a machine base; a mold installed in the machine base; a bottom plate horizontally arranged on the machine base; a drive chamber opened on the bottom plate near the machine base; a roller chamber opened on the bottom plate near the drive chamber; a lifting chamber opened on the bottom plate away from the machine base; a rear plate vertically installed on the bottom plate away from the machine base; a clamping plate slidably installed on the rear plate near the machine base in the vertical direction; a push assembly installed on the bottom plate; and a drive assembly installed on the bottom plate. This application has the effect of improving the stability of the steel plate when it is processed.

[0004] In order to solve the problem that when the steel plate is bent by the forming knife, the edges will warp or even shake on both sides away from the forming knife, and the steel plate cannot be stably bent, the existing technology adopts the method of setting a pushing component, a driving component and a buffer plate. However, there are baffles on both sides of the existing bending machine, and the overall height of the steel plate after bending will change, which makes it inconvenient to bend the long steel plate, and the mold blocks the pushing of the steel plate. Utility Model Content

[0005] The purpose of the utility model is to provide a bending machine for steel plate processing to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A bending machine for steel plate processing, comprising a conveying platform, a lifting device is fixedly installed on the bottom surface of the conveying platform, a conveying device is movably installed inside the conveying platform, a limiting device is fixedly installed on the surface of the conveying platform, and a bending device is fixedly installed on one side of the conveying platform;

[0008] The bending device comprises a box unit and a bending unit, and the bending unit is fixedly installed on the surface of the box unit.

[0009] A further improvement of the technical solution of the utility model is that the conveying platform includes a conveying table plate, a mounting groove is opened on the surface of the conveying table plate, a driving box is fixedly installed on the side of the conveying table plate, and a buffer sheet is fixedly installed on the surface of the conveying table plate.

[0010] A further improvement of the technical solution of the utility model is that the lifting device includes connecting rods fixedly installed at the four ends of the bottom surface of the conveying table, and support rods are movably installed at the bottom of the connecting rods. A lifting cylinder is fixedly installed in the middle of the bottom surface of the conveying table. By setting up the lifting device, the conveying table can be moved up and down by the lifting cylinder, so that the steel plate can be lifted and moved forward after bending, preventing the bent part from being limited by the mold and unable to move forward automatically, requiring manual intervention.

[0011] A further improvement of the technical solution of the utility model is that: the conveying device includes a gear motor fixedly installed inside a driving box, a main conveying roller and an auxiliary conveying roller are movably installed inside the conveying table, and connecting tracks are movably installed on the surfaces of the main conveying roller and the auxiliary conveying roller. The main conveying roller and the auxiliary conveying roller are connected by connecting tracks, so that all rollers have the operating force for conveying, thereby preventing the steel plate from being too heavy, resulting in a slow transmission speed of a single drive affecting the processing efficiency, and long-term negative pressure from easily causing damage.

[0012] A further improvement of the technical solution of the utility model is that the limiting device includes a servo motor fixedly mounted on the surface of the conveying table, a threaded rod is fixedly mounted on the output end of the servo motor, and the surface of the threaded rod and the inner surface of the conveying table are movably connected, a limiting plate is movably mounted on the surface of the threaded rod, and the threaded rod is driven by the servo motor to move the limiting plate downward, so as to limit the steel plate and prevent the steel plate from floating up and down during the bending process.

[0013] A further improvement of the technical solution of the utility model is that the box unit includes an equipment box fixedly installed on one side of the conveying table, the top surface of the equipment box is provided with a slide groove, and the surface of the equipment box is fixedly installed with a positioning block, which can facilitate the replacement of the mold through the slide groove and is fixed by using the positioning block.

[0014] A further improvement of the technical solution of the utility model is that the bending unit includes a support frame fixedly installed on the surface of the equipment box, a forming knife is fixedly installed on the top of the support frame, and a mold is fixedly installed on the surface of the equipment box. The bending operation can be achieved by pressing the steel plate into the mold through the forming knife on the support frame.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] The utility model provides a bending machine for steel plate processing. By changing the structure of a conveying platform and a bending device, both ends of the conveying platform are free of obstruction and shielding, so that long steel plates or continuous bending operations can be realized, the efficiency of the bending processing can be effectively improved, and the problem of processing restrictions caused by limited space can be reduced.

[0017] The utility model provides a bending machine for steel plate processing, which connects the main conveying roller and the auxiliary conveying roller by connecting the crawler, so that all rollers have the operating force for conveying, thereby preventing the steel plate from being too heavy, resulting in a slow single-drive conveying speed affecting the processing efficiency, and long-term negative pressure from easily causing damage.

[0018] The utility model provides a bending machine for steel plate processing. By arranging a lifting device, the up and down movement of the conveying table can be realized by a lifting cylinder, so that the steel plate can be lifted up and moved forward after bending, preventing the bent part from being limited by a mold and unable to move forward automatically, requiring manual intervention.
