Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a sheet metal bending machine provided with a clamp for clamping a sheet. Background Art

[0002] A bending machine is a common sheet metal processing device. The bending machine can be used to bend the sheet metal, so as to bend the sheet metal into the required shape and angle. When the bending machine bends the sheet metal, it usually clamps it with a clamp. One is to increase the safety during operation, and the other is to avoid displacement of the sheet metal during bending, thereby affecting the bending effect. However, the existing sheet metal bending machine with a clamp still has some shortcomings. For example, although it can clamp and fix the sheet metal, some sheets will warp at both ends when they are bent, and the existing clamp cannot adjust the angle according to the warping of the sheet metal, which makes it impossible to effectively cooperate with the bending machine to bend the sheet metal. For this reason, we propose a sheet metal bending machine provided with a clamp for clamping the sheet metal. Utility Model Content

[0010] Furthermore: the length of the movable slot from left to right is greater than half of the length of the operating table from left to right.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The sheet metal bending machine is provided with a clamp for clamping a plate. When the bending machine body bends the plate through the bending mechanism inside it, the plate is pressed and the two ends thereof will be warped. A pin shaft is provided between the bending machine body and the operating table, so that a hinge effect can be achieved.

In this way, the telescopic rod can support the operating table without affecting its angle adjustment. In this way, the entire clamp can not only clamp and fix the plate, but also change the angle as the plate is warped. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Embodiment 1:

[0018] See also Figure 1-2 The utility model provides a technical solution: a sheet metal bending machine provided with a clamp for clamping a plate, comprising a bending machine body 1, an operating table 2 is provided in the middle of the right side of the bending machine body 1, when the plate is bent, the plate is first placed on the top of the operating table 2, and then the staff can push the plate to the right side of the feeding port of the bending machine body 1, so that the bending part of the plate moves to the bending mechanism inside the bending machine body 1, and the front and rear end surfaces of the right middle part of the bending machine body 1 are both provided with connecting blocks 3, and the connecting blocks 3 are connected to the front and rear ends of the operating table 2. A pin 4 is hingedly provided between the rear end surfaces, and the pin 4 can achieve a hinged effect between the bending machine body 1 and the operating table 2, so that when bending a large plate, the operating table 2 can adjust the angle simultaneously with the warping of the plate. Support blocks 5 are provided on the front and rear end surfaces of the right bottom of the bending machine body 1, and telescopic rods 6 are provided on the inner sides of the support blocks 5. Pins 2 7 are hingedly provided between the telescopic rod 6 and the support blocks 5. Through the connection of the pins 2 7, the telescopic rod 6 and the support blocks 5 can achieve a hinged effect, so that The telescopic rod 6 can be adjusted in angle. A moving groove 8 is horizontally arranged on the right side of the front and rear end surfaces of the operating table 2. A clamping block 9 matching the moving groove 8 is arranged on the inner end of the telescopic rod 6 away from the support block 5. When the operating table 2 is adjusted in angle, the clamping block 9 will move left and right in the moving groove 8. At the same time, the clamping block 9 will drive the telescopic rod 6 to adjust the angle and stretch its length. The front and rear end surfaces of the right middle part of the bending machine body 1 are both provided with a limit block 10, and the limit blocks 10 are respectively fitted on the front and rear end surfaces of the left bottom of the operating table 2. The limit block 10 provided can play the effect of supporting the operating platform 2, so that the operating platform 2 can reach a right angle of 90 degrees with the bending machine body 1 at normal times. A mounting plate 11 is provided in the middle of the front and rear end surfaces of the top of the operating platform 2, and an electric push rod 12 is provided on the opposite surface of the mounting plate 11.

[0019] Among them, preferably, a plurality of groups of ball grooves are evenly arranged on one end of the clamping plate 13 away from the electric push rod 12, and a plurality of groups of balls 14 are arranged through the ball grooves on the other end of the clamping plate 13 away from the electric push rod 12.
