[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0031] Combine the following Figures 1 to 6 The utility model describes a hydraulic support top beam bending plate mold.

[0032] Specifically, the hydraulic support top beam bending plate mold includes an upper mold 2 and a lower mold 1.

[0033] The end surface of the lower mold 1 used to cooperate with the upper mold 2 is provided with an arc-shaped groove 101 and a first inclined surface 102. The end surface of the lower mold 1 used to cooperate with the upper mold 2 refers to the side of the lower mold 1 used to dock with the upper mold 2. The first inclined surface 102 is connected to the side wall of one side of the arc-shaped groove 101, and when the upper mold 2 and the lower mold 1 are in a state of cooperation, along the end of the first inclined surface 102 close to the arc-shaped groove 101 to the end away from the arc-shaped groove 101, the first inclined surface 102 is inclined in a direction away from the upper mold 2. Specifically, refer to Figure 1 As shown, the width direction of the arc groove 101 is along Figure 1 The arc groove 101 is arranged in the vertical direction, the length direction of the arc groove 101 is arranged in the direction perpendicular to the paper surface, and the annular groove passes through the lower mold 1 along the length direction, so that the arc groove 101 is convenient for milling and the processing difficulty of the arc groove 101 is reduced. Figure 1 In the embodiment, the first inclined surface 102 is arranged below the arc-shaped groove 101 and is connected to the side wall of the arc-shaped groove 101 below. Figure 1 The left side is tilted.

[0034] The upper die 2 is used to connect with a pressure device, for example, the pressure device can be a press. An end of the upper die 2 away from the pressure device is provided with an arc-shaped protrusion 201 for docking with the arc-shaped groove 101 and a second inclined surface 202 for docking with the first inclined surface 102. It should be noted that the size of the arc-shaped protrusion 201, the size of the arc-shaped groove 101, the position size of the first inclined surface 102 relative to the arc-shaped groove 101, and the position size of the second inclined surface 202 relative to the arc-shaped protrusion 201 can be determined based on the material, thickness, bending radius and springback angle of the blank of the bent plate 3.

[0035] The hydraulic support top beam bending plate mold provided in the embodiment of the utility model is connected to the pressure equipment through the upper mold 2. During the preparation process, the blank is placed between the upper mold 2 and the lower mold 1, and the upper mold 2 is driven by the pressure equipment to dock with the lower mold 1. The arc-shaped protrusion 201 of the upper mold 2 is placed in the arc-shaped groove 101 of the lower mold 1, so that the arc-shaped groove structure 301 of the bent plate 3 is formed between the arc-shaped protrusion 201 and the arc-shaped groove 101, and the second inclined surface 202 of the upper mold 2 is docked with the first inclined surface 102 of the lower mold 1, so that the flanging structure 302 of the bent plate 3 is formed between the first inclined surface 102 and the second inclined surface 202.

[0036] With such an arrangement, the bent plate 3 can be formed in one step through the upper die 2 and the lower die 1, which can not only improve the forming consistency of the bent plate 3, thereby improving the continuity of the subsequent automatic welding process, but also improve the forming efficiency of the bent plate 3, saving working hours and manpower.

[0037] In some embodiments provided by the present invention, a threaded hole 203 is provided on the end surface of the upper mold 2 for connecting with the pressure equipment, and the upper mold 2 is connected to the pressure head of the pressure equipment through the threaded hole 203. Specifically, the threaded connector can pass through the pressure head of the pressure equipment and connect with the threaded hole 203, thereby fixing the upper mold 2 on the pressure head of the pressure equipment.

[0038] Such an arrangement makes it easy to install the upper mold 2 on the pressure head of the pressure equipment, or to remove it from the pressure head of the pressure equipment.

[0039] In some embodiments provided by the utility model, both sides of the end surface of the upper mold 2 for connecting with the pressure equipment are provided with a limit plate 204, and the limit plate 204 is used to limit the pressure head of the pressure equipment. During use, the pressure head of the pressure equipment is placed between the limit plates 204 on both sides. In this way, through the cooperation of the limit plates 204 and the pressure head of the pressure equipment, on the one hand, the upper mold 2 can be accurately positioned relative to the pressure head, and on the other hand, the upper mold 2 can be prevented from shifting during the cooperation between the upper mold 2 and the lower mold 1.

[0040] In some embodiments provided by the present invention, the upper mold 2 is configured as a plate machining structure. Figure 3 and Figure 4 As shown, in the process of manufacturing the upper mold 2, a plate is first prepared, and an arc-shaped protrusion 201 and a second inclined surface 202 are processed on one side of the plate, and a limit plate 204 and a threaded hole 203 can also be processed on the other side of the plate. In this way, the upper mold 2 is set as an integrated structure, so that the overall strength of the upper mold 2 is higher.

[0041] Of course, the upper mold 2 is not limited to being set as a plate machining structure. For example, in other embodiments provided by the present invention, the upper mold 2 is set as a plate welding structure. Specifically, the upper mold 2 may include two side plates, a bottom plate and a top plate.

The two side plates can also protrude from the side of the top plate away from the bottom plate, so that the part of the side plate protruding from the top plate serves as a limit plate 204, for example, the arc-shaped protrusion 201 and the second inclined surface 202 can be processed on the bottom plate by bending or machining with a press. With such a configuration, for a larger upper mold 2, its processing difficulty and its own weight can be reduced.

[0042] In some embodiments provided by the present invention, the upper die 2 is quenched, so as to increase the hardness of the upper die 2, avoid the problem that the upper die 2 is scratched or damaged by the bent plate 3, and extend the service life of the upper die 2.

In this way, a smooth curved transition is also formed between the arc-shaped groove structure 301 and the flange structure 302 of the bent plate 3, thereby reducing the stress of the bent plate 3 and improving the strength of the bent plate 3.

[0044] In some embodiments provided by the present invention, the lower die 1 is configured as a plate machining structure. Figure 1 and Figure 2 As shown, in the process of manufacturing the lower mold 1, a plate is prepared first, and an arc groove 101 and a first inclined surface 102 are processed on one side of the plate. In this way, the lower mold 1 is set as an integrated structure, so that the overall strength of the lower mold 1 is higher.

For example, in other embodiments provided by the present utility model, the lower mold 1 is set as a plate welding structure. Specifically, the lower mold 1 may include two side plates and a top plate. Figure 1 and Figure 2 As shown, the two side panels are arranged opposite to each other, for example, the two side panels are arranged Figure 2The top plate is connected between the two side plates, and the top plate can form an arc groove 101 and a first inclined surface 102. For example, the arc groove 101 and the first inclined surface 102 can be processed on the top plate by bending or machining with a press. In this way, for a lower die 1 with a larger size, its processing difficulty and its own weight can be reduced.

[0046] In some embodiments provided by the present invention, the lower die 1 is quenched, so as to increase the hardness of the lower die 1, avoid the problem that the lower die 1 is scratched or damaged by the bent plate 3, and extend the service life of the lower die 1.
