Description

Technical Field

[0001] This utility model relates to the field of sheet metal punching and shearing feeding devices, and in particular to a feeding mechanism for sheet metal punching and shearing equipment. Background Technology

[0002] In the production of steel furniture, a sheet metal feeding device is required to feed the cabinet panels. This device primarily uses a drive mechanism to power a pair of feeding rollers. Existing sheet metal feeding devices have a relatively fixed structure, which leads to the following problems during practical use:

[0003] 1. In the existing sheet material feeding equipment, the upper and lower feeding rollers are directly mounted on the support frame of the sheet material feeding equipment through bearings. The distance between the upper and lower feeding rollers cannot be adjusted. Once the upper and lower feeding rollers are worn, the distance between them will increase, affecting the conveying effect of the sheet material.

[0004] 2. Since the distance between the existing upper and lower feeding rollers cannot be adjusted, in the actual production process, the upper and lower feeding rollers can only meet the conveying of plates of fixed thickness, and cannot meet the feeding and conveying operation of plates of different thicknesses, which limits the production and use needs of enterprises. Summary of the Invention

[0005] The purpose of this utility model is to provide a feeding mechanism for sheet metal punching and shearing equipment. Its overall structure is scientifically designed and easy to install, use and operate. In use, the feeding mechanism of this utility model can adjust the distance and pressure between the upper feeding roller and the lower feeding roller, thereby ensuring the conveying effect of the feeding roller and the working applicability range. To achieve the above objectives, the present invention adopts the following technical solution:

[0030] The installation and use process of the feeding mechanism for a sheet metal punching and shearing equipment according to this utility model is as follows: I. Installation process:

[0031] First, the installer can install the load-bearing frame assembly 1. Specifically, the installer can install the left support 11 together with the right support 12 via the upper connecting rod 13 and the lower connecting rod 14. The upper connecting rod 13 is fixedly connected to the left support 11 and the right support 12 respectively; the lower connecting rod 14 is fixedly connected to the left support 11 and the right support 12 respectively. Then, the working drive assembly 2 is installed. Specifically, the drive motor 21 can be installed on the side of the load-bearing frame assembly 1 to provide rotational torque. The motor shaft is installed on the drive motor 21, and the motor drive wheel 22 is installed on the motor shaft. The synchronous wheel 24 is installed on one side of the lower conveyor roller group 7. The motor drive wheel 22 is connected to the synchronous wheel 24 via the synchronous belt 23. After the installation is completed, the upper conveyor roller assembly 3 and the angle adjustment assembly 4 can be installed. During installation, one side of the hinge shaft 33 can be installed on the load-bearing frame assembly 1, and the other side of the hinge shaft 33 is hinged to the first adjustment frame 31 and the second adjustment frame 32. An upper conveyor roller assembly 34 and a drive rod 35 are installed between an adjustment frame 31 and a second adjustment frame 32. The upper conveyor roller assembly 34 and the lower conveyor roller assembly 7 are in contact via toothed meshing. The two sides of the upper conveyor roller assembly 34 and the drive rod 35 are mounted on the first adjustment frame 31 and the second adjustment frame 32 via bearings. When installing the angle adjustment assembly 4, the upper part of the cylinder mounting seat 42 can be movably mounted on the upper connecting rod 13, and the adjusting cylinder 41 is mounted on the lower part of the cylinder mounting seat 42.

At this time, the upper conveyor roller assembly 34 installed between the first adjusting frame 31 and the second adjusting frame 32 can be adjusted in angle. The distance between the upper conveyor roller assembly 34 and the lower conveyor roller assembly 7 can then be adjusted to accommodate feeding plates of different thicknesses. After the distance adjustment is completed, the operator can rotate the rotating drive part 52 in the first adjusting clamping part 5 and the second adjusting clamping part 6 to drive the clamping screw 53 to rotate and move downwards. When the bottom of the clamping screw 53 contacts the connecting frame 36, the clamping screw 53 can clamp and position the upper conveyor roller assembly 3 through the clamping connecting frame 36.
