Description

Technical Field

[0001] The invention relates to the technical field of sheet metal processing equipment, in particular to a feeding mechanism. Background Art

[0002] Sheet metal is a processing technology. So far, there is no complete definition of sheet metal. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold processing technology for metal sheets (usually less than 6mm), including shearing, punching / cutting / compounding, folding, riveting, splicing, forming (such as car body), etc. Its most notable feature is that the thickness of the same part is consistent.

[0003] However, the existing feeding mechanism has a complicated manual process, which requires manual placement of materials at different workstations and adjustment of angles. During this process, workers need to run back and forth, which is a high-intensity work process.

[0004] Moreover, the existing feeding mechanism is time-consuming to position the workpiece, which reduces the overall production efficiency. The bent sheet metal is manually fed to the bending mouth, positioned and then bent. The material is bulky and laborious, and the processing accuracy may be further reduced due to human jitter. Some bent products require workers to work relatively close to the bending mouth, which poses certain safety hazards. Therefore, it does not meet the existing usage needs. Summary of the invention

[0005] The object of the present invention is to provide a feeding mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a feeding mechanism comprises a frame, support tables are installed on both sides of the top of the frame, a feeding rotating mechanism is arranged between the two adjacent support tables, and the feeding rotating mechanism is installed at the inner bottom end of the frame, a positioning mechanism is installed on one side of the top of the frame, and the positioning mechanism is located on one side of the support table, the positioning mechanism comprises a limit block, a cross roller guide, a guide connecting plate, a needle bearing, a right bearing connecting plate, a right connecting seat, a mold spring, a spring stopper, a spring adjusting screw, a movable platform cover and a slide module, the movable platform cover is installed on one side of the top of the slide module, the top of the movable platform cover is installed with a guide connecting plate, the top of the guide connecting plate is installed with a cross roller guide, the top of the cross roller guide is installed with a right connecting seat, the top of the right connecting seat is installed with a right bearing connecting plate, and the top of the right bearing connecting plate is installed with a needle bearing, the feeding rotating mechanism comprises an X-axis screw module, a Y-axis screw module, a rotating module and a suction cup.

[0007] Preferably, a mounting hole is opened on one side outer wall of the right connecting seat, a mold spring is arranged in the mounting hole, and the mounting hole on the outer wall of the right connecting seat is connected to the spring stopper through a spring adjusting screw.

[0008] Preferably, a limit block is installed on one side outer wall of the guide rail connecting plate.

[0009] Preferably, a Y-axis screw module is installed on the slider on the X-axis screw module.

[0010] Preferably, a rotating module is installed on the slider on the Y-axis screw module.

[0011] Preferably, a suction cup is installed on the top of the rotating module.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) The present invention positions the workpiece by setting a positioning mechanism. The material is manually placed on the support table, and the size parameters of the material are set. The mobile platform cover of the positioning mechanism moves under the drive of the slide module to a position X / 2 from the center axis (X is the material width) as a positioning reference; the positioning mechanism will move toward the center, and when the motor senses that the resistance has increased to a certain extent, the slide module stops moving; a mold spring is installed on the structure of the positioning mechanism, so that the bearing connecting plate can play a certain buffering role when it moves toward the center and is pressed tightly, thereby preventing rigid contact and damage to the overall structure. From the above, it can be seen that the present invention keeps workers away from the bending mouth through the setting of the positioning mechanism, greatly improving the safety of the operation. Workers only need to input parameters to bend multiple times without having to adjust the material placement manually, thereby improving work efficiency.

[0014] (2) Through the setting of the feeding rotating mechanism, when the workpiece needs to be placed at different workstations, the feeding rotating mechanism moves toward the direction of the adjacent positioning mechanism to reach the bottom of the material, and then uses the suction cup to absorb the material. The feeding rotating mechanism moves a certain distance to the middle of the support table, and then the feeding rotating mechanism rotates the material to a specified angle as required. The feeding rotating mechanism moves different distances as required to achieve the purpose of transporting to different workstations and meet the material requirements of different workstations. (The motor moving distance is provided by the encoder feedback information of the motor.) Therefore, the present invention simplifies the manual process, does not need to manually adjust the material placement, further improves work efficiency, reduces labor intensity, improves the loading accuracy of the workpiece, improves operation safety, and is highly practical.
