Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to a front feeding medium-thick plate clamp device for a plate shearing machine. Background Art

[0002] Before the plate shearing machine performs plate shearing work, it is necessary to convey the plate body to the plate shearing station. In the prior art, the plate is generally pushed to the designated position by a pushing method. Pushing requires the rear stop of the plate shearing machine for positioning. Since tearing sarcomas are generated during the shearing of medium-thick plates, the positioning is inaccurate. In the prior art, in order to solve the above problems, a clamp device is also used to clamp the plate and then convey it. However, the clamping force of the clamp device in the prior art is generally insufficient, resulting in unstable conveyance during the conveyance process. Summary of the Utility Model

[0003] The utility model provides a front feeding medium-thick plate clamp device for a plate shearing machine, which can make the clamping mechanism clamp more stably.

[0025] The second clamp part 20, which has at least a second set length, and the front end of the second clamp part 20 is the second clamping part corresponding to the first clamping part. An articulated connection is formed at the middle position between the first clamp part 10 and the second clamp part 20 so that the first clamp part 10 can move relative to the second clamp part 20 in a first direction and a second direction. When the first clamp part 10 moves relative to the second clamp part 20 in the first direction, the first clamping part approaches the second clamping part; when the first clamp part 10 moves relative to the second clamp part 20 in the second direction, the first clamping part moves away from the second clamping part;

[0026] The driving cylinder 100, which is installed at the rear end of the first clamp part 10, and the front end of the telescopic component 120 of the driving cylinder 100 is in sliding contact with the rear end of the second clamp part 20.

[0027] A plate shearing machine front feeding medium-thick plate clamp device provided in this embodiment includes a first clamp part 10, a second clamp part 20 and a driving cylinder 100. An articulated connection is formed at the middle position between the first clamp part 10 and the second clamp part 20. The front ends of the first clamp part 10 and the second clamp part 20 are respectively a first clamping part and a second clamping part. The driving cylinder 100 drives the tails of the first clamp part 10 and the second clamp part 20 so that the fronts of the first clamp part 10 and the second clamp part 20 approach each other to clamp the plate. Moreover, the housing of the driving cylinder 100 is fixed at the tail of the first clamp part 10, and the front end of the telescopic part 120 of the driving cylinder 100 acts on the second clamp part 20. Therefore, it can ensure that the first clamp part 10 and the second clamp part 20 have a large clamping force to clamp the plate, and make the clamped plate more stable.

[0028] In a further implementable manner of this embodiment, the front end of the telescopic part 120 is formed with an arc surface.

[0029] The front end of the telescopic part 120 in this embodiment is an arc surface, which can make it more convenient for the front end of the telescopic part 120 to form a sliding contact with the upper surface of the second clamp part 20.

[0030] In a further implementable manner of this embodiment, a first clamp block 30 is arranged on the side of the first clamping part close to the second clamp part 20, and a second clamp block 40 is arranged on the side of the second clamping part close to the first clamp part 10.

The slope 201 is used to contact the surface of the first clamp part 10, and the slope 201 extends obliquely downward from the front end to the rear end of the second clamp part 20.

[0034] The driving cylinder 100 in this embodiment is fixed at the tail. When the telescopic part 120 of the driving cylinder 100 retracts, under the action of the gravity of the driving cylinder 100, the fronts of the first clamp part 10 and the second clamp part 20 open, so as to no longer clamp the plate. When the first clamp part 10 contacts the slope 201 under the action of the gravity of the driving cylinder 100, the first clamp part 10 is reset.

[0035] In a further implementable manner of this embodiment, a positioning member 60 is provided on the side surface of the second clamp portion 20.

[0036] In a further implementable manner of this embodiment, a lateral bracket 50 is fixed to the side surface of the second clamp portion 20, and the positioning member 60 is installed on the lateral bracket 50.
