DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1-4As shown, the metal frame intelligent stamping forming equipment is composed of a stamping slot 1 as a basic structure. The stamping slot 1 is U-shaped, and the front and rear of the stamping slot 1 are connected. There are flat tables 11 on the left and right sides of the top of the stamping slot 1. The flat table 11 on one side can be connected to the welding platform of the mesh plate frame. The welded mesh plate frame can be directly pushed to the surface of the flat table 11, and the middle part of the mesh plate frame is located on the upper part of the stamping slot 1;

[0030] The structure of the stamping assembly is as follows:

[0031] like Figure 1 , Figure 5 , Figure 6 As shown, a cylinder 3 is vertically installed at the rear of the punching groove 1, and the lifting body 2 is in a square shape. A sliding cavity 21 is provided in the lifting body 2, and a sliding body 7 slides vertically in the sliding cavity 21, and the sliding body 7 is elastically connected to the lifting body 2 through a spring, and the sliding body 7 is connected to the telescopic end of the cylinder 3 through an extension arm 22. A reinforcing arm 23 is symmetrically fixed at the rear of the lifting body 2, and a slider is fixed at the end of the reinforcing arm 23. A slide rail is vertically installed on the inner wall of the punching groove 1, and the slider is slidably connected to the slide rail, so that the lifting body 2 can be stably lifted and lowered, and a support assembly 6 is set at the four top corners of the lifting body 2;

[0032] The oil cylinder 3 is opened and retracted, and the slide body 7 and the lifting body 2 are driven down through the extension arm 22. The two support components 6 at the lower part of the lifting body 2 press the mesh plate frame downward along the inner wall of the stamping groove 1, so that the mesh plate frame forms a U-shaped frame in the stamping groove 1.

[0033] The structure of the flip-press component is as follows:

[0034] like Figure 4 As shown, two flaps 5 are symmetrically rotated and installed at the edge of the stamping slot 1, and a gear 51 is coaxially fixed to the flap 5. A rack 52 is vertically aligned with the edge of the gear 51. The rack 52 is connected to the telescopic end of the oil cylinder 3 through a bracket 53. When the flap 5 is attached to the plane table 11, a flat surface is formed to avoid blocking the movement of the mesh plate frame;

[0035] like Figure 5 , Figure 7 As shown, the locking assembly includes a square rod 72, a plurality of partition grooves 71 penetrating the bottom of the sliding body 7 are provided on the side of the sliding body 7, the square rod 72 is slidably inserted into the lifting body 2 from the rear of the lifting body 2, and the square rod 72 is connected to the lifting body 2 through a spring, the square rod 72 is located on the side of the sliding body 7, and the surface of the square rod 72 has a blocking column 73, the blocking column 73 blocks the bottom of the sliding body 7 so that the sliding body 7 cannot descend in the sliding cavity 21, and a third wedge block 74 is fixed to the outer end of the square rod 72, the inclined surface of the third wedge block 74 is downward, and the fourth wedge block 75 is connected to the side wall of the stamping groove 1 through the mounting bracket 76, the inclined surface of the fourth wedge block 75 is upward, and the third wedge block 74 and the fourth wedge block 75 are vertically aligned;

[0036] When the oil cylinder 3 drives the lifting body 2 to press down the mesh plate frame, the blocking column 73 blocks the bottom of the sliding body 7, so that the sliding body 7 cannot descend in the sliding cavity 21, and the sliding body 7 and the lifting body 2 descend together to punch the mesh plate frame. When the lifting body 2 presses the mesh plate frame to the bottom of the stamping groove 1, the lifting body 2 cannot continue to descend, and the rack 52 just engages with the gear 51. At the same time, the third wedge block 74 is squeezed by the inclined surface of the fourth wedge block 75, so that the square rod 72 overcomes the elastic force and slides in a straight line. The blocking column 73 is aligned with the partition groove 71 to release the obstruction to the sliding body 7, and then the oil cylinder 3 is continuously driven to contract, so that the sliding body 7 overcomes the elastic force and can descend in the sliding cavity 21. The gear 51 is driven to rotate through the rack 52, so that the flap 5 is flipped 180° to bend the tops on both sides of the U-shaped frame toward the middle into a plane. At this time, the square frame is stamped and formed.

[0037] like Figure 4 As shown, a plurality of rollers 54 are arranged and rotatably arranged on one side of the flap 5 that contacts the frame. When the flap 5 turns over to bend the frame, the rollers 54 make the flap 5 roll in contact with the frame, thereby reducing friction and promoting the bending of the frame.

[0038] The structure of the pusher assembly is as follows:

[0039] like Figure 4 As shown, two slideways 41 are provided on the bottom surface of the stamping slot 1, and the slideways 41 extend from the rear portion of the stamping slot 1 to the front portion. A push plate 42 is slidably installed in the slideways 41, and the push plate 42 protrudes from the bottom surface of the stamping slot 1. The first cylinder 4 is installed at the rear portion of the stamping slot 1, and the telescopic end of the first cylinder 4 is connected to the push plate 42;

[0040] like Figure 8 As shown, the support assembly 6 includes a telescopic frame 62, which is slidably inserted into the lifting body 2. A limiting groove 63 is provided on the surface of the lifting body 2. A limiting rod 64 is fixed to the telescopic frame 62. The limiting rod 64 moves in the limiting groove 63 to limit the sliding position of the telescopic frame 62. The limiting rod 64 is connected to the lifting body 2 through a spring. A row of rollers 61 are rotatably provided at the outer end of the telescopic frame 62, and a first wedge block 65 is fixed to the inner end of the telescopic frame 62.

[0041] The linear motion assembly includes an insertion rod 66, which is inserted into the lifting body 2 by sliding from the front side, a second wedge block 67 is fixedly connected to the insertion rod 66, a second wedge block 67 is positioned at the oblique surface of the first wedge block 65, an outer end of the insertion rod 66 is connected to a seat frame 68, a second cylinder 69 is installed on the surface of the seat frame 68, and a telescopic end of the second cylinder 69 is connected to the front part of the lifting body 2;

[0042] During the frame stamping process, the second wedge block 67 squeezes and contacts the first wedge block 65, causing the telescopic frame 62 to slide outward, and the roller 61 supports the bending part of the frame. After the square frame is stamped and formed, the oil cylinder 3 is turned on and extended. Under the action of elastic force, the sliding body 7 rises in the sliding cavity 21, and the height of the lifting body 2 does not change. The rack 52 moves up to drive the gear 51 to rotate, so that the flap 5 rotates to the surface of the flat table 11, and then the second cylinder 69 is turned on and extended, so that the seat frame 68 pulls the insertion rod 66 outward, and the second wedge block 67 gradually releases the first wedge block 65. Under the action of elastic force, the telescopic frame 62 shrinks into the lifting body 2, and the four groups of rollers 61 shrink synchronously without contacting the inner side of the frame. Then the first cylinder 4 is turned on and extended, and the first cylinder 4 pushes the push plate 42 to slide along the slide 41. The push plate 42 pushes the bottom of the frame, and the frame is pushed out from the front side of the stamping groove 1 to complete the discharge.

[0043] like Figure 8 As shown, the roller 61 is aligned one by one with the rods of the square frame, and the edge of the roller 61 has a groove for snapping into the rods of the square frame. During the bending process of the frame, the rods at the bending parts of the frame are snapped into the grooves of the roller 61 one by one, so that the rods can be accurately bent in an arc shape, avoiding excessive deformation of the bending parts of the frame.
