DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 , the utility model provides a technical solution:

[0021] A bending press comprises a bracket 1, wherein the four corner ends of the bracket 1 are fixedly connected with supporting frames 2, and the middle position of the top of the bracket 1 is fixedly connected with a bending table body 3, the front and rear ends of both sides of the bending table body 3 are fixedly connected with guide stands 5, a metal plate workpiece 6 is placed above the bending table body 3, an upper push plate 7 is provided at the top of the guide stand 5, an auxiliary push plate 8 is fixedly connected to the top of the upper push plate 7, and a slider 9 is fixedly connected to the middle position of the bottom end of the upper push plate 7, a first telescopic rod 10 is connected to the front end of the slider 9, guide rods 11 are slidably connected to the two sides of the upper push plate 7, and the guide rods 11 are fixedly connected to the bending table body 3.

[0022] like Figure 1 , Figure 3 and Figure 5As shown, the support stand 2 has an "L"-shaped structure, and there are two groups of support stands 2. The horizontal ends of the support stands 2 are fixedly connected to the auxiliary top plate 12. When the equipment is started, the two groups of support stands 2 mainly support the auxiliary top plate 12. Second telescopic rods 13 are fixedly installed on both sides of the auxiliary top plate 12, and the movable ends of the second telescopic rods 13 are connected to the limiting clamping seat 14. A bending die body 15 is fixedly installed at the middle position of the bottom end of the limiting clamping seat 14, and the shape of the limiting clamping seat 14 is a "cross"-shaped structure. The second telescopic rod 13 is connected to the limiting clamping seat 14 and the bending die body 15. The die body 15 is provided with a transmission connection. When the equipment is stamping and processing the metal plate, the setting of the "cross"-shaped limiting holder 14 mainly plays a role in assisting the second telescopic rod 13 to transfer to the bending die body 15; a shaping groove 4 is provided in the middle position of the bending table body 3 through integral molding, and the inner end of the shaping groove 4 and the lower half of the bending die body 15 are arranged in a shape-matching manner, and the shaping groove 4 and the metal plate workpiece 6 are arranged adjacent to each other in the upper and lower positions. Under the setting of matching shapes, the equipment will use the stamping force to press the part of the metal plate to be bent into the inside of the shaping groove 4 when it is actually started, so that it can be plastically shaped.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the connection between the upper push plate 7 and the slider 9 constitutes a "T"-shaped structure, and the upper push plate 7 is symmetrically arranged along the transverse central axis of the bending table body 3 as an axis of symmetry. The top of the upper push plate 7 is fixedly connected with an auxiliary push plate 8 with a semicircular structure. The first telescopic rod 10 is embedded in the upper part of the guide stand 5. The two groups of upper push plates 7 are respectively arranged at the front and rear ends of both sides of the metal plate workpiece 6. By respectively arranging second telescopic rods 13 at the upper parts of the front and rear groups of guide stands 5, the second telescopic rod 13 after startup will push the upper push plate 7 and the auxiliary push plate 8 back and forth, so that they can use the generated unidirectional thrust to push the metal plate to the center processing position.

[0024] Working process: When the bending press needs to be used to process metal plates, the metal plates to be processed can be placed horizontally on the bending table body 3 first. Then, as the two sets of first telescopic rods 10 move toward the placement direction of the metal plates, the upper push plate 7 and the auxiliary push plate 8 are pushed back and forth by the slider 9, so that the equipment can push the metal plates to the middle position of the bending table body 3, that is, inside the shaping groove 4. The second telescopic rod 13 will pass through the limiting seat 14 and carry the bending die body 15 to punch the metal plate downward, so that the middle end can be plasticized inside the shaping groove 4, and a single metal plate bending operation can be completed.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
