Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to a tooling for quick assembly of bending machine forgings. Background Technology

[0002] Existing bending machine feeding fixtures are mostly linear conveyor structures, which, together with clamping fixtures, can complete the processing of sheet metal. However, when dealing with curved forging structures, traditional linear conveyor and clamping equipment cannot effectively fix and feed them. Utility Model Content

[0003] The purpose of this utility model is to provide a quick assembly tooling for forgings in a bending machine. The rotating structure of the side-extension bending frame, combined with the angle locking of the horizontal carrier plate, forms a spatial dual-degree-of-freedom adjustment, allowing the suction cup assembly to conform to complex curved surface contours. This solves the problem that traditional linear tooling cannot fix non-planar forgings and addresses the issues in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly bending machine forging fixture, comprising a fixture bracket, a side-bending frame, and a forging suction cup assembly, wherein the side-bending frame is installed on both sides above the fixture bracket, the fixture bracket includes a positioning locking shaft and a damping hinge, the positioning locking shaft is welded to the damping hinge, the side-bending frame is rotatably connected to the damping hinge, and both ends of the side-bending frame are provided with horizontal carrier plates, the horizontal carrier plates being rotatably connected to the side-bending frame through toothed limiters.

[0005] Through the above solution, the toothed limiter 202 provides quick angle locking without the need for repeated bolt tightening, thus shortening tooling preparation time.

[0006] Preferably, the forging suction cup assembly is located above the horizontal carrier plate, and the forging suction cup assemblies are arranged horizontally.

[0007] Preferably, the forging suction cup assembly includes a silicone disc and a support shaft, the support shaft being a hollow structure, and the silicone disc and the support shaft being connected by a slot.

[0008] Preferably, one end of the support shaft is provided with an exhaust valve hole located inside the silicone disc, and the other end of the support shaft is provided with an adjusting bottom valve, which is rotatably connected to the support shaft.

[0009] The above scheme enables differentiated control of single-point adsorption force by independently adjusting the bottom valve 305, thus avoiding adsorption failure of curved forgings due to local suspension.

[0010] Preferably, the outer surface of the support shaft is provided with an air pipe interface, which is interconnected with the exhaust valve hole.

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

[0012] 1. In this utility model, the rotation structure of the side-extension curved frame, combined with the angle locking of the horizontal carrier plate, forms a spatial dual-degree-of-freedom adjustment, allowing the suction cup assembly to conform to complex curved surface contours, thus solving the problem that traditional linear tooling cannot fix non-planar forgings.

[0013] 2. In this utility model, the positioning locking shaft at the bottom of the tooling bracket is connected to the feed rail of the bending machine to achieve linear conveying of the entire tooling. During the bending process, the elastic deformation of the silicone disc compensates for the slight displacement of the forging, avoiding surface damage caused by rigid clamping. After processing, the vacuum is turned off, the adsorption force is released, and the forging can be quickly unloaded. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To address the issue that existing bending machine feeding fixtures, which are mostly linear conveyor structures, can effectively fix and feed curved forgings when used with clamping fixtures, while capable of processing sheet metal, please refer to [link to relevant documentation]. Figure 1-3 The present invention provides the following solution:

[0020] A quick-assembly bending machine forging fixture includes a fixture bracket 1, a side-bending frame 2, and a forging suction cup assembly 3. The side-bending frame 2 is installed on both sides above the fixture bracket 1. The fixture bracket 1 includes a positioning lock shaft 101 and a damping hinge 102. The positioning lock shaft 101 is welded to the damping hinge 102. The side-bending frame 2 is rotatably connected to the damping hinge 102. Horizontal carrier plates 201 are provided at both ends of the side-bending frame 2. The horizontal carrier plates 201 are rotatably connected to the side-bending frame 2 through toothed limiters 202.

[0021] In this embodiment, the positioning lock shaft 101 at the bottom of the tooling bracket 1 is connected to the feed rail of the bending machine to achieve linear conveying of the entire tooling. During the bending process, the elastic deformation of the silicone disc 301 compensates for the small displacement of the forging, avoiding surface damage caused by rigid clamping. After processing, the vacuum is turned off, the adsorption force is released, and the forging can be quickly unloaded.

[0022] The forging suction cup assembly 3 is located above the horizontal carrier plate 201. The forging suction cup assemblies 3 are arranged horizontally. The forging suction cup assembly 3 includes a silicone disk 301 and a support shaft 303. The support shaft 303 is a hollow structure. The silicone disk 301 and the support shaft 303 are connected by a slot. One end of the support shaft 303 is provided with an exhaust valve hole 302, which is located inside the silicone disk 301. The other end of the support shaft 303 is provided with an adjusting bottom valve 305, which is rotatably connected to the support shaft 303. The outer surface of the support shaft 303 is provided with an air pipe interface 304, which is connected to the exhaust valve hole 302.

[0023] In this embodiment, the operator manually adjusts the rotation angle of the two side-mounted curved frames 2 around the damping hinge 102 according to the curvature of the forging surface. The toothed limiter 202 locks the horizontal tilt angle of the horizontal carrier plate 201 to ensure that the bearing surface of the suction cup assembly matches the local curvature of the forging. The damping hinge 102 provides rotational resistance to prevent the side-mounted curved frames from deflecting unexpectedly due to gravity, thereby improving positioning stability. The forging is placed on the forging suction cup assembly 3. The external vacuum equipment injects negative pressure airflow into the cavity of the support shaft 303 through the air pipe interface 304. The negative pressure is transmitted through the cavity of the support shaft to the exhaust valve hole 302, causing the silicone disk 301 to generate an adsorption force and stick tightly to the surface of the forging. The bottom valve 305 can be rotated to adjust the cross-sectional area of ​​the airflow channel inside the support shaft, thereby achieving fine adjustment of the single-point adsorption force and adapting to the force requirements of different areas of the curved surface.
