Description

Technical Field

[0001] The utility model belongs to the technical field of metal plate bending, and particularly relates to a material pushing component for metal plate bending. Background Art

[0002] In the field of metal plate processing, bending is one of the common processes. A bending machine is needed in the bending process. A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base is composed of a seat shell, a coil and a cover plate. The coil is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by a wire, and after power is turned on, gravity is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base.

[0003] Then during the bending process, a pushing device is needed to transport the workpiece. Traditional pushing components generally place the workpiece on a workbench and then push it through an electric telescopic rod.

[0004] Existing sheet metal bending and pushing components may have the following limitations when used:

[0005] 1. Poor adaptability: Traditional pusher components may only be able to fix workpieces of one or several specific sizes and cannot flexibly adapt to metal plates of different sizes and shapes, limiting their versatility.

[0006] 2. Unstable fixation: Some pusher components may not be able to effectively limit the movement of the workpiece, causing the workpiece to shift during the bending process, affecting the bending accuracy and quality.

[0007] 3. Easy to fall off problem: If the pushing component cannot firmly fix the workpiece, the workpiece may fall off during the pushing process, which not only affects the production efficiency but also may cause safety hazards.

[0008] 4. Bending quality is affected: The deviation and falling off of the workpiece will directly lead to the decline of bending quality, and problems such as uneven creases and angle deviation may occur, which requires rework or scrapping, increasing costs.

[0009] To this end, we proposed a metal plate bending pusher, which is not only suitable for the limit fixation of different workpieces, but also can prevent deviation and falling off during pushing, thereby improving the quality of the processing. Utility Model Content

[0010] The purpose of the utility model is to provide a pushing member for bending a metal plate, which is not only suitable for limiting and fixing different workpieces, but also can prevent deviation and falling off from occurring during pushing, thereby improving the quality of the produced processing.

[0011] The technical solutions adopted in this utility are as follows:

[0012] A pusher member for bending a metal plate, comprising a support leg and a workbench arranged on the top of the support leg, a pusher assembly is arranged on one side of the workbench, a slide groove and a through hole are opened on the workbench, a rotating rod is arranged inside the through hole, a driving assembly is arranged at the bottom of the rotating rod, and a semicircular extrusion block is arranged on the top of the rotating rod;

[0013] A sliding assembly is arranged inside the slide groove, a first U-shaped limit block is arranged on the sliding assembly, the outer side of the first U-shaped limit block is in contact with the vertical surface of the semicircular extrusion block, and a first roller is rotatably arranged inside the U-shaped groove of the first U-shaped limit block;

[0014] A rotating assembly is arranged on the top of the first U-shaped limit block, a second U-shaped limit block is arranged on the rotating assembly, and a second roller is arranged inside the U-shaped groove of the second U-shaped limit block.

[0015] Furthermore, the pushing assembly includes a connecting plate connected to the workbench, an electric telescopic rod is provided on the connecting plate, and a pushing plate is installed at the telescopic end of the electric telescopic rod.

[0016] Furthermore, the driving assembly includes a bracket fixedly arranged at the bottom of the workbench, a motor is arranged on the bracket, and an output end of the motor is connected to the rotating rod.

[0017] Furthermore, the rotating rods are provided in two groups, and the two groups of rotating rods are connected by a transmission belt.

[0018] Furthermore, the sliding assembly includes a fixed shaft arranged inside the sliding groove, a sliding block and a spring are sleeved on the fixed shaft, the springs are arranged on both sides of the sliding block, and the top of the sliding block is connected to the first U-shaped limit block.

[0019] Furthermore, the rotating assembly is arranged on a rotating seat at the top of the first U-shaped limit block, a threaded rod is arranged on the rotating seat, a rotating disk is arranged on the top of the threaded rod, and a threaded sleeve is sleeved on the threaded rod, and one side of the threaded sleeve is connected to the second U-shaped limit block through a connecting rod.

[0021] The technical effects achieved by this utility model are:

DETAILED DESCRIPTION

[0030] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0031] like Figure 1-4As shown, the technical solution adopted by the utility model is specifically as follows: a pushing member for bending a metal plate, comprising a supporting leg 1 and a workbench 2 arranged on the top of the supporting leg 1, a pushing component is arranged on one side of the workbench 2, and a slide groove 3 and a through hole are opened on the workbench 2, a rotating rod 4 is arranged inside the through hole, a driving component is arranged at the bottom of the rotating rod 4, and a semicircular extrusion block 5 is arranged on the top of the rotating rod 4;

[0032] A sliding assembly is arranged inside the slide groove 3, and a first U-shaped limit block 6 is arranged on the sliding assembly. The outer side of the first U-shaped limit block 6 is in contact with the vertical surface of the semicircular extrusion block 5, and a first roller 7 is rotatably arranged inside the U-shaped groove of the first U-shaped limit block 6;

[0033] A rotating assembly is arranged on the top of the first U-shaped limit block 6 , a second U-shaped limit block 20 is arranged on the rotating assembly, and a second roller 8 is arranged inside the U-shaped groove of the second U-shaped limit block 20 .

[0034] Its working principle is as follows: first, the workpiece to be bent is placed on the workbench 2, and then the driving assembly drives the rotating rod 4 to rotate the semicircular extrusion block 5. When rotating, the arc surface of the semicircular extrusion block 5 contacts the first U-shaped limit block 6 and drives the sliding assembly to move inside the slide groove 3, thereby limiting the left and right sides of the workpiece. The rolling of the first roller 7 can not only fix the workpieces of different widths, but also prevent the workpieces from deviating to the left and right sides when pushed by the pushing assembly, resulting in the phenomenon of reduced bending quality. At the same time, by rotating the rotating assembly, the second U-shaped limit block 20 is driven to move downward when the rotating assembly rotates, thereby limiting the top of the workpiece. The rolling of the second roller 8 can not only fix the workpieces of different thicknesses, but also prevent the workpieces from falling off when pushed by the pushing assembly, resulting in the phenomenon of reduced bending quality. The device is not only suitable for the limit fixation of different workpieces, but also can prevent the deviation and falling off when pushed, thereby improving the quality of the processing.

[0035] Among them, in order to ensure the stability between the arc surface of the semicircular extrusion block 5 and the first U-shaped limit block 6 and prevent sliding, an anti-slip surface is provided at the joint between the arc surface of the semicircular extrusion block 5 and the first U-shaped limit block 6. The anti-slip surface can increase the friction force when pushing and prevent it from sliding when limiting.

[0036] like Figure 1 As shown, the pushing assembly includes a connecting plate 9 connected to the workbench 2, on which an electric telescopic rod is provided, and a pushing plate 11 is installed at the telescopic end of the electric telescopic rod, and the pushing plate 11 is driven by the electric telescopic rod to push the workpiece.

[0037] By providing the first roller 7 and the second roller 8, the friction force of pushing can be reduced, thereby improving the pushing effect. At the same time, the first roller 7 and the second roller 8 can be limited when rotating to prevent the pushing deviation phenomenon from occurring.

[0038] like Figure 4 As shown, the driving assembly includes a bracket fixedly arranged at the bottom of the workbench 2, on which a motor 12 is arranged, and the output end of the motor 12 is connected to the rotating rod 4. The rotating rod 4 is driven to rotate by the motor 12, thereby causing the semicircular extrusion block 5 to rotate.

[0039] Among them, the utility model is provided with two groups of rotating rods 4, and the two groups of rotating rods 4 are connected by a transmission belt 13. When the motor 12 drives one of the rotating rods 4 to rotate, the other rotating rod 4 is driven to rotate by the transmission belt 13. By setting two semicircular extrusion blocks 5, the extrusion force can be evenly applied, thereby improving the limiting effect.

[0040] like Figure 2 As shown, the sliding assembly includes a fixed shaft 14 arranged inside the slide groove 3, a slider 15 and a spring 16 are sleeved on the fixed shaft 14, springs 16 are arranged on both sides of the slider 15, and the top of the slider 15 is connected to the first U-shaped limit block 6. When the first U-shaped limit block 6 moves, the slider 15 is driven to squeeze the spring 16, thereby limiting and fixing the left and right sides of the workpiece. The purpose of setting the spring 16 is not only to reduce the pressure, but also to enable the first U-shaped limit block 6 to quickly return to its original position through the elastic force of the spring 16.

[0041] like Figure 2 As shown, the rotating assembly is arranged on a rotating seat at the top of the first U-shaped stopper 6, a threaded rod 17 is arranged on the rotating seat, a rotating disk is arranged on the top of the threaded rod 17, and a threaded sleeve 18 is sleeved on the threaded rod 17, and one side of the threaded sleeve 18 is connected to the second U-shaped stopper 20 through a connecting rod. The threaded rod 17 is driven to rotate on the rotating seat by the rotating disk, and then the threaded sleeve 18 drives the connecting rod to move the second U-shaped stopper 20 downward, thereby limiting and fixing the top of the workpiece.

[0042] In order to enable the threaded sleeve 18 to move downward, an L-shaped limit rod 19 is provided on the other side of the threaded sleeve 18, and the bottom of the L-shaped limit rod 19 is arranged inside the first U-shaped limit block 6. Such a setting can limit the threaded sleeve 18 and will not cause the threaded sleeve 18 to rotate but only move downward.

[0043] The working principle of the utility model is as follows: firstly, the workpiece to be bent is placed on the workbench 2, and then the driving assembly drives the rotating rod 4 to rotate the semicircular extrusion block 5. When rotating, the arc surface of the semicircular extrusion block 5 contacts the first U-shaped limit block 6 and drives the sliding assembly to move inside the slide groove 3, thereby limiting the left and right sides of the workpiece. The rolling of the first roller 7 can not only fix the workpieces of different widths, but also prevent the workpieces from deviating to the left and right sides when being pushed by the pushing assembly, resulting in the phenomenon of reduced bending quality. At the same time, by rotating the rotating assembly, the second U-shaped limit block 20 is driven to move downward when the rotating assembly rotates, thereby limiting the top of the workpiece. The rolling of the second roller 8 can not only fix the workpieces of different thicknesses, but also prevent the workpieces from falling off when being pushed by the pushing assembly, resulting in the phenomenon of reduced bending quality. The device is not only suitable for the limit fixation of different workpieces, but also can prevent the deviation and falling off when being pushed, thereby improving the quality of the processing.

[0044] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
