Description

Technical Field

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

[0002] A bending machine is a device widely used in the field of metal processing. It is mainly used to bend metal sheets into specific shapes and angles. The bending machine bends the metal sheets by applying force. When the applied force exceeds the bending strength of the metal material, the material will undergo plastic deformation and form a curved shape. Traditional bending machines require manual feeding and discharging during operation. Therefore, if the workpiece only needs one bending to be formed, it is more troublesome to manually discharge it. In this solution, a bending machine for processing metal sheets that can be bent and formed once is designed. This makes it convenient for manual feeding and there is no need to worry about the discharging operation. You only need to repeat the feeding operation, which speeds up the discharging efficiency and reduces the difficulty of the work. Utility Model Content

[0027] like Figure 1-3 As shown, the utility model provides an embodiment of a bending machine for processing metal sheets, comprising a tilted processing table 1, wherein the processing table 1 is provided with a push plate 13 and a folding plate 16 hinged to the push plate 13, wherein the push plate 13 is fixedly mounted on the top of the first inner cavity 11 of the processing table 1, and the folding plate 16 is movably arranged on the top of the second inner cavity 12, and the folding plate 16 is driven by the electro-hydraulic push rod 5 to cause the edge of the metal sheet 4 to be processed to bend upward or to bend downward to cause the metal sheet 4 to be processed to be discharged rearward;

[0028] A clamping assembly 2 is installed above the processing table 1. The clamping assembly 2 includes a first pressure block 23. The first pressure block 23 is driven by a first cylinder 21. Specifically, the first cylinder 21 and the first pressure block 23 are connected by a first piston rod 22. The first cylinder 21 is arranged obliquely. The first cylinder 21 is installed on a bracket 14. The bracket 14 is built on the edge of the processing table 1. The inclination of the bracket 14 is consistent with the inclination of the processing table 1.

[0029] The push-in plate 13 is provided with a hollow ejection hole 132 at one end facing the folding plate 16, and a second cylinder 24 is installed below the ejection hole 132. The second cylinder 24 is arranged perpendicular to the processing table 1, and the second piston rod 25 on the second cylinder 24 is movable obliquely upward perpendicular to the processing table 1. The movable end of the second piston rod 25 is provided with a second pressure block 26. The ejection hole 132 is circular, and the area of ​​the ejection hole 132 is larger than the area of ​​the second pressure block 26. In order to facilitate the limited pushing of the metal plate 4 to be processed, the front and rear sides of the push-in plate 13 are provided with clamping plates 131 for limiting.

[0030] The folding plate 16 is provided with an avoidance groove 161 on one side close to the push-in plate 13. The avoidance groove 161 is a rectangular groove. The longitudinal length of the avoidance groove 161 is less than the length of the same side of the metal plate 4 to be processed, and is much less than the length of the metal plate 4 to be processed on the same side. Because the avoidance groove is only used to facilitate flipping and limiting, and the edge of the avoidance groove 161 provides bending pressure to the metal plate 4 to be processed, the avoidance groove 161 is set as small as possible during the setting process. A positioning component 3 is provided on the folding plate 16, and the positioning component 3 includes a fixed mounting The third cylinder 31 on the folding plate 16, the third piston rod 32 of the third cylinder 31 moves toward one end of the avoidance groove 161, and the movable end of the third piston rod 32 is fixedly connected to the third pressure block 33. In order to facilitate the installation of the third cylinder 31, an L-shaped semi-closed hanger 15 is installed under the pushing plate 13, and the second cylinder 24 is installed in the hanger 15; when in use, the edge to be bent of the metal plate 4 to be processed is pushed to one side of the third pressure block 33, and the first pressure block 23 presses the inner side of the metal plate 4 to be processed onto the avoidance groove 161.

[0031] When in use, first start the third cylinder on the folding plate, so that the third cylinder can press the upper end of the edge of the avoidance groove. At this time, the electro-hydraulic push rod is in the first state, and then the metal plate to be processed is pushed along the pushing plate to one side of the folding plate, and the third pressure block above the avoidance groove is pressed against it. Then start the first cylinder, and the first pressure block is driven by the first cylinder to press the metal plate to be processed above the avoidance groove. It should be noted that the edge of the first pressure block is just pressed against the upper end of the other side of the avoidance groove. At this time, the inclined surface of the processing table presents Figure 1 Then start the electro-hydraulic push rod to lift the folding plate, so that the folding plate is folded along the hinge center to the specified angle to achieve the bending effect. At this time, the length of the bent edge is Figure 3The short side length of the middle avoidance groove, at this time the electro-hydraulic push rod is in the second state; when the bending is completed, the electro-hydraulic push rod is closed to restore it to the first state, the processing table is kept in the inclined setting, the first cylinder and the third cylinder are closed, the second cylinder is opened, and the second cylinder is used to drive the second pressure block to jack up outward, and the metal plate is sent out and is higher than the height of the inclined surface + the third cylinder. Under the inertia of the metal plate, the processed metal plate is made to slide backward along the third cylinder to send the metal plate out; the first cylinder and the third cylinder can also be closed, and the second cylinder is opened, and the second cylinder is used to drive the second pressure block to jack up outward. At this time, the electro-hydraulic push rod is retracted to a lower position, that is, the third state, that is, it is recovered to below Figure 1 The height makes it easier for the metal plate to slide out directly after being pushed by the second cylinder, and the sliding out is smoother, solving the problem of manual operation of feeding and discharging.

Any improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention. Therefore, the scope of protection of this utility model patent shall be based on the appended claims.
