[0029] In order to make the forging plate bracket 6 lightweight, the forging plate bracket 6 is divided into two groups. The top of the forging plate bracket 6 is a horizontal strip structure 61 , and the strip structure 61 is fixed to the mold frame 1 with a support 62 below.

[0030] In order to make the forging raw material plate 10 and the top surface of the forging plate bracket 6 have an inclined downward movement tendency when they are separated; the strip plate structure 61 on both sides of the forging plate bracket 6 is inclined and bent downward.

[0031] In order to ensure that the pushing plate mechanism 2 will only push the lowest forging raw material plate 10 when pushing the forging raw material plate 10, and will not push two or three groups of forging raw material plates 10; the top surface of the pushing forging plate bracket 6 and the bottom surface of the angle steel seat 3 are provided with a distance difference of the thickness of the forging raw material plate 10.

[0032] In order to make the angle steel seat 3 fit the forging raw material plates 10 of different lengths, the angle steel seat 3 is fixed on the mold frame 1 by a length adjustment component 4, and the length adjustment component 4 includes: a support 41, a slide bar 42, a slider 43, a moving plate 44, a cylinder 45, a connecting seat 46, and a fixed plate 48; the fixed plate 48 is horizontally fixed on the mold frame 1 by a support 41, and two groups of parallel slide bars 42 are provided on the fixed plate 48. The movement direction of the slide bars 42 and the servo slide 21 are perpendicular. Each group of slide bars 42 is slidably matched with a slider 43, and the two groups of sliders 43 are fixed on a plate-like structure moving plate 44 above. A cylinder 45 is fixed on the moving plate 44, and the movement direction of the cylinder 45 is parallel to the direction of the slide bar 42. The telescopic end of the cylinder 45 is fixed to the upper surface of the fixed plate 48 by a connecting seat 46, and the two groups of angle steel seats 3 on the same side are fixed to the moving plate 44 through the width adjustment component 5.

[0033] In order to allow the angle steel seat 3 to be fitted with forging raw material plates 10 of different widths, the width adjustment component 5 includes: a mounting seat 51, a horizontal slot 52, a fixing bolt 53, and a connecting sleeve 54; the mounting seat 51 is a block structure, and there are two groups of them respectively fixed on both sides of the moving plate 44, and the mounting seat 51 is provided with two groups of parallel horizontal slots 52, and each group of horizontal slots 52 is provided with a fixing bolt 53, and each group of fixing bolts 53 is screwed with a connecting sleeve 54, and the connecting sleeve 54 is vertically fixedly connected to the adjacent angle steel seat 3.

[0034] In order to prevent the forging raw material plate 10 from shifting due to inertia when it is pushed to the forging channel 8, each group of moving plates 44 is provided with a horizontal mounting strip 47 on the side close to the angle steel seat 3 below, and a limiting component 7 is fixed on the mounting strip 47. The limiting component 7 includes: a sliding beam 71, a plate seat 74, and a limiting plate 75, wherein the sliding beam 71 is fixed in parallel to the mounting strip 47, the plate seat 74 is slidably fitted on the sliding beam 71, and a limiting plate 75 with a plate-like structure is fixed on the plate seat 74, and the limiting plate 75 is perpendicular to the upper surface of the mold frame 1 and perpendicular to the movement direction of the servo slide 21.

[0035] In order to reduce the cantilever pressure of the sliding beam 71 in the limiting assembly 7, a vertically downward support rod 72 is fixed to the end of the sliding beam 71 away from the moving plate 44, and a support wheel 73 is fixed under the support rod 72. The support wheel 73 is tangent to the upper surface of the mold frame 1, and the rolling direction of the support wheel 73 is parallel to the direction of the slide bar 42.

[0036] In order to prevent the deflection block 27 from being limited in movement by the forging raw material plate 10 when it is reset, the deflection block 27 is rotatably embedded in the embedded groove 25 around the rotating shaft 26. When the deflection block 27 is embedded in the embedded groove 25, the top surfaces of the deflection block 27 and the push block 24 are flush, and the top surface of the push block 24 coincides with the top surface of the forging plate bracket 6.

[0037] Brief description of the usage process:

[0038] When in use, a forging machine is fixed above the forging channel 8, and a forging die is fixed below the forging channel 8. Figure 4 As shown, the forging raw material plates 10 are arranged and placed on the top surfaces of all forging plate brackets 6, and all the forging raw material plates 10 are limited at right angles by four groups of angle steel seats 3. When forging is required, the servo slide 21 in the push plate mechanism 2 is started, and the servo slide 22 on the servo slide 21 moves toward the side of the limiting plate 75. The servo slide 22 drives the two groups of push blocks 24 to move through the push plate 23, and the deflection blocks 27 on the two groups of push blocks 24 follow the movement. Under the action of the torsion spring, the deflection block 27 remains inclined, and the push groove 28 on the deflection block 27 is stuck on the side of the lowest forging raw material plate 10, and then the moving deflection block 27 pushes the lowest forging raw material plate 10 away until the forging raw material plate 10 falls into the forging channel 8 and falls into the forging die below the forging channel 8, and then the forging machine fixed above the forging channel 8 passes through the forging channel 8 to forge the forging raw material plate 10 in the forging die.

[0039] The forging raw material plates 10 in the remaining angle steel seats 3 are all moved downward by one unit under the action of gravity, waiting for the next pushing operation; when the forging forming operation of the next group of forging raw material plates 10 is required, the servo slide 21 and the servo slide 22 drive the servo slide 22, the push plate 23, the push block 24, and the deflection block 27 to reset. Because of the establishment of the slope surface 29, when the deflection block 27 is reset, the lowest forging raw material plate 10 will limit the slope surface 29. Under the limiting effect, the deflection block 27 will rotate around the rotating shaft 26, so that the deflection block 27 is embedded in the embedded groove 25, and then the push plate mechanism 2 continues to reset, so that the deflection block 27 is separated from the bottom of the forging raw material plate 10. Under the action of the torsion spring on the rotating shaft 26, the deflection block 27 returns to its original angle. Figure 5 As shown, wait for the next push operation.

[0040] When the length of the forging raw material plate 10 changes, it is necessary to adaptively adjust the length of the projected rectangle between the angle steel seats 3, and the adjustment is performed through the length adjustment component 4. At this time, the driving cylinder 45 contracts or extends, and the contracted or extended cylinder 45 changes the distance between the connecting seat 46 and the driving cylinder 45. Because the driving cylinder 45 is fixed on the moving plate 44, and the connecting seat 46 is fixed on the fixed plate 48, the driving cylinder 45 will drive the moving plate 44 and the fixed plate 48 to slide relative to each other. At this time, the slide bar 42 and the slider 43 provide sliding guidance and assistance. Because the fixed plate 48 is fixed on the mold frame 1 with a support 41, the moving moving plate 44 will drive the width adjustment component 5 and the angle steel seat 3 on the same side to move in the length direction, thereby completing the length of the rectangle projected by the angle steel seat 3, and then making the projected length between the angle steel seats 3 adapt to the changed length of the raw material plate 10.

[0041] When the width of the forging raw material plate 10 changes, it is necessary to adaptively adjust the rectangular width of the angle steel seat 3, and adjust it through the width adjustment component 5. At this time, loosen the fixing bolt 53, change the horizontal position of the fixing bolt 53 in the horizontal slot 52, and then change the width between the two groups of angle steel seats 3 on the same side. Adjust the width between the two groups of angle steel seats 3 on both sides of the push plate mechanism 2 to be consistent and make their positions correspond, and then re-lock the fixing bolt 53 to complete the change in the width of the rectangle projected by the angle steel seat 3, so that the projected width between the angle steel seats 3 can adapt to the changed width of the raw material plate 10.

[0042] When the width of the forging raw material plate 10 changes, it is necessary to adaptively adjust the position of the limit plate 75 in the limit assembly 7 to prevent the falling position of the forging raw material plate 10 from deviating from the forging channel 8; because the sliding beam 71 is fixed to the moving plate 44 by the mounting strip 47, the sliding beam 71 will follow the movement of the moving plate 44 when adjusting the length, so it will not cause limitation to the forging raw material plate 10 whose size has changed. At this time, the sliding beam 71 slides the plate seat 74, and the plate seat 74 drives the limit plate 75 to slide on the sliding beam 71, thereby changing the position of the limit plate 75 to adapt to the size of the forging raw material plate 10. When the forging raw material plate 10 falls, the limit plate 75 will limit the farthest horizontal displacement of the forging raw material plate 10, thereby preventing the falling position of the forging raw material plate 10 from deviating from the forging channel 8.

[0043] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
