[0003] Forging equipment is mainly used for metal forming, which is formed by applying pressure to the metal. Generally, forging equipment uses manual feeding, which is not only inefficient but also dangerous in the feeding process.

[0025] The lower end of the rotating plate 3 is in rotational contact with the upper end of the annular lifting seat 4. The lower end of the rotating plate 3 is fixedly connected with a plurality of limit clamping seats 32 in an annular array.

[0027] See also Figure 2 , Figure 4 , Figure 6 and Fig. 9 The positioning mechanism includes a positioning seat 5 symmetrically distributed between two L-shaped support seats 33, and convex sliders 51 symmetrically fixedly connected to both sides of the positioning seat 5.

[0028] The forged piece is placed between the two positioning seats 5 and the two ends or both sides of the forged piece are clamped by the V-shaped positioning grooves on the sides of the two positioning seats 5, so as to achieve positioning of the forged piece.

[0029] See also Figure 6 and Fig. 9 The adjusting mechanism includes a two-way transmission screw 52 arranged on the side of the two positioning seats 5, both ends of the two-way transmission screw 52 are protrudingly arranged on the rotating shaft, the two-way transmission screw 52 is installed in a convex groove 34 on the side of an L-shaped support seat 33, and the two-way transmission screw 52 is rotatably connected to the two side walls of the convex groove 34 through the rotating shaft. The sides of the convex sliders 51 on one side of the two positioning seats 5 are penetrated with threaded holes, and the two convex sliders 51 with threaded holes are symmetrically sleeved on the two-way transmission screw 52. The end of the rotating shaft at one end of the two-way transmission screw 52 passes through the inner side of the L-shaped support seat 33 and the annular block 6 in turn and is fixedly connected to the connecting block 53.

[0030] The bidirectional transmission screw 52 is driven to rotate forward or reversely by rotating the rotating handle 54. The rotation of the bidirectional transmission screw 52 drives the two convex sliders 51 thereon to move closer to or away from each other. The two convex sliders 51 drive the two positioning seats 5 to move closer to or away from each other. The distance between the two positioning seats 5 is adjusted, so that the positioning mechanism can position the forged parts of different sizes and models, thereby improving the application range of the feeding device.

[0031] See also Figure 6 , Figure 7 and Fig.10 The locking mechanism includes a concave bracket 7 symmetrically fixedly connected to the side of the connecting block 53, a pressing block 71 rotatably connected to the concave bracket 7 through a circular axis, a locking block 72 fixedly connected to one end of the pressing block 71, and a locking spring 73 fixedly connected to the pressing end of the pressing block 71. The pressing end of the pressing block 71 is close to the rotating handle 54, the locking block 72 is engaged with the positioning slot 61, and one end of the locking spring 73 is in contact with the connecting block 53.

[0032] When the adjusting mechanism needs to be adjusted to adjust the positioning mechanism, the locking mechanism needs to first release the locking of the adjusting mechanism, and press the pressing ends of the two pressing blocks 71 toward the connecting block 53, so that the pressing ends of the pressing blocks 71 squeeze the locking spring 73. At this time, the other end of the pressing block 71 rises, and the locking block 72 is driven by the pressing block 71 to separate from the positioning slot 61 on the side of the annular block 6. At this time, the rotating handle 54 can be rotated at will; After the positioning mechanism is adjusted, stop rotating the handle 54 and release the pressure on the two pressing blocks 71. Under the action of the elastic force of the locking spring 73, the pressing block 71 is reset. At this time, the end of the pressing block 71 drives the locking block 72 to be clamped into the positioning groove 61 on the side of the annular block 6, so that the rotating handle 54 and the connecting block 53 cannot rotate, thereby locking the adjustment mechanism.

[0033] See also Figure 3 , Figure 8 and Fig. 9 A contraction groove 35 is provided on the side of the L-shaped support seat 33, and the bearing assembly includes a bearing block 8 slidably connected in the contraction groove 35, and a return spring 82 symmetrically fixed to the side of the bearing block 8 of the mounting seat, the return spring 82 is installed in the contraction groove 35, one end of the return spring 82 abuts against the contraction groove 35, one end of the bearing block 8 is a slope, and a lower edge strip 81 is fixedly connected to the bearing block 8 at the lower end of the slope, and the outer side surface of the lower edge strip 81 is in the same side plane as the end surface of the bearing block 8 with the slope, and the lower end of the lower edge strip 81 is The surface is in the same horizontal plane as the lower end surface of the L-shaped support seat 33, one end of the L-shaped support seat 33 is movably connected with an L-shaped transmission plate 83, one end of the L-shaped transmission plate 83 passes through the L-shaped support seat 33 and extends into the contraction groove 35 and is fixedly connected to the side of the bearing block 8, the L-shaped transmission plate 83 is arranged between two return springs 82, the upper end of the forging table 2 is symmetrically fixedly connected with the extrusion blocks 21 on both sides of the lower die 23, the upper end of the extrusion block 21 is provided with a slope, and the L-shaped transmission plate 83 and the extrusion block 21 are distributed correspondingly up and down.

[0034] The lower end of the positioning seat 5 is in sliding contact with the upper end of the bearing block 8, and the bearing block 8 supports the forged part. The two positioning seats 5 and the two bearing blocks 8 cooperate to well position and support the forged part. When the L-shaped support seat 33 moves downward, the bearing assembly is driven to move downward. When the lower end of the L-shaped transmission plate 83 in the bearing assembly contacts the upper end of the extrusion block 21, the L-shaped transmission plate 83 abuts against the extrusion block 21. At this time, the bearing assembly continues to move downward, and the L-shaped transmission plate 83 slides along the extrusion block 21. The extrusion block 21 pushes the L-shaped transmission plate 83 to move, so that the L-shaped transmission plate 83 slides outward along the L-shaped support seat 33, and the L-shaped transmission plate 83 drives the bearing block 8 to move into the contraction groove 35. When the lower end of the L-shaped support seat 33 and the upper end of the lower die 23 are in the same horizontal plane, the L-shaped support seat 33 stops moving downward. At this time, the slope of the bearing block 8 contacts the lower end of the forged piece. During forging, the upper die is driven downward by the hydraulic cylinder of the forging equipment body 1, and the forged piece is pressed downward by the upper die. The lower end of the forged piece slides downward along the slope of the bearing block 8. At the same time, the forged piece pushes the bearing block 8 to continue sliding into the contraction groove 35, and the lower edge strip 81 contracts into the L-shaped support seat 33. At this time, the forged piece slides downward along the side of the bearing block 8 and the lower edge strip 81 into the die cavity of the lower die 23. The forging piece is forged by the cooperation of the upper die and the lower die 23. The positioning seat 5, the bearing block 8 and the lower edge strip 81 are arranged so that the forging piece can accurately slide into the lower die 23 to ensure the forging quality of the forging piece.

[0035] Working principle: When the forging piece needs to be loaded, the forging piece is placed between the two positioning seats 5, so that the lower end of the forging piece is placed on the upper end of the bearing block 8. At this time, the V-shaped positioning grooves on the sides of the two positioning seats 5 are stuck at the two ends or both sides of the forging piece, and the positioning mechanism and the bearing assembly are used to coordinate to achieve the positioning of the forging piece. The inner rod of the hydraulic cylinder 43 extends upward to drive the support plate 42 to move upward, the support plate 42 drives the annular lifting seat 4 to move upward, the annular lifting seat 4 drives the rotating plate 3 to move upward, the rotating plate 3 drives the L-shaped support seats 33 at both ends to move upward, the L-shaped support seats 33 drive the bearing assembly and the positioning mechanism to move upward, and the bearing assembly and the positioning mechanism drive the forged parts to move upward; By rotating the output shaft of the stepper motor by half a circle, the output shaft drives the regular polygonal column 22 to rotate 180 degrees, the regular polygonal column 22 drives the rotating plate 3 to rotate 180 degrees, the rotating plate 3 drives the L-shaped support seats 33 at both ends to rotate 180 degrees, the rotating plate 3 drives the limit clamping seat 32 to rotate along the annular groove 41 on the inner side of the annular lifting seat 4, so that the rotating plate 3 can rotate stably, and the positioning mechanisms and bearing assemblies at both ends of the rotating plate 3 exchange positions with each other, and the positioning mechanisms and bearing assemblies drive the forged parts to rotate to the top of the lower die 23, so that the forged parts can be stably moved, and the rapid loading of the forged parts can be completed, and the staff does not need to manually send the forged parts to the forging equipment body 1, thereby ensuring the safety of the staff.

[0036] The inner rod of the hydraulic cylinder 43 contracts downward to drive the support plate 42 to move downward, and the support plate 42 drives the annular lifting seat 4 to move downward. The annular lifting seat 4 drives the rotating plate 3 to move downward through the limit clamping seat 32, and the rotating plate 3 drives the bearing assembly and the positioning mechanism to move downward through the L-shaped support seat 33. At this time, the forged part above the lower die 23 moves downward along with the bearing assembly and the positioning mechanism. At this time, the lower end of the L-shaped transmission plate 83 in the bearing assembly first contacts the upper end of the extrusion block 21, and the inner rod of the hydraulic cylinder 43 continues to shrink, so that the L-shaped transmission plate 83 slides downward along the extrusion block 21, and the extrusion block 21 pushes the L-shaped transmission plate 83 to move, so that the L-shaped transmission plate 83 slides outward along the L-shaped support seat 33, and the L-shaped transmission plate 83 drives the bearing block 8 to move into the shrinkage groove 35; When the lower end of the L-shaped support seat 33 and the upper end of the lower die 23 are in the same horizontal plane, the L-shaped support seat 33 stops moving downward. Under the action of the gravity of the forged piece, the slope of the bearing block 8 contacts the lower end of the forged piece. During forging, the upper die is driven downward by the hydraulic cylinder of the forging equipment body 1, and the forged piece is pressed downward by the upper die. The lower end of the forged piece slides downward along the slope of the bearing block 8. At the same time, the forged piece pushes the bearing block 8 to continue sliding into the contraction groove 35, and the lower edge strip 81 contracts into the L-shaped support seat 33. At this time, the forged piece slides downward along the side of the bearing block 8 and the lower edge strip 81 into the die cavity of the lower die 23. The forging piece is forged by the cooperation of the upper die and the lower die 23. The positioning seat 5, the bearing block 8 and the lower edge strip 81 are arranged so that the forging piece can accurately slide into the lower die 23 to ensure the forging quality of the forging piece.

[0037] When a forging operation is performed on a piece to be forged, the positioning mechanism at the other end of the rotating plate 3 can be loaded with materials, and the piece to be forged can be placed between the two positioning seats 5 and supported by the bearing assembly.

[0038] After forging is completed, the upper die of the forging equipment body 1 moves upward and resets. At this time, the inner rod of the hydraulic cylinder 43 extends upward, so that the rotating plate 3 drives the bearing components and the positioning mechanism at both ends to move upward, so that the lower end of the L-shaped transmission plate 83 in the bearing component is away from the extrusion block 21. Under the action of the elastic force of the reset spring 82, the bearing block 8 moves outward along the contraction groove 35, so that the bearing block 8 is reset to wait for the loading of the next forged part; At this time, the output shaft of the stepper motor rotates half a circle, and the rotating plate 3 is driven to rotate 180 degrees through the regular polygonal column 22, so that the positioning mechanisms and bearing components at both ends of the rotating plate 3 exchange positions with each other, and the forging piece to be forged is rotated to the top of the lower die 23 through the positioning mechanism and the bearing component, waiting for the next forging operation, and so on. During the forging process of the previous forging piece, the next forging piece can be placed on the bearing component at the same time and clamped and fixed by the positioning mechanism, which greatly improves the efficiency of loading.

[0039] When it is necessary to load forged parts of different sizes, the two pressing blocks 71 are pressed, and the pressing end of the pressing block 71 squeezes the locking spring 73. At this time, the other end of the pressing block 71 drives the locking block 72 to separate from the positioning groove 61 on the side of the annular block 6. At this time, the rotating handle 54 can be rotated at will; By rotating the rotating handle 54, the bidirectional transmission screw 52 is driven to rotate forward or reverse, so that the two convex sliders 51 are moved closer to or away from each other, and the two convex sliders 51 drive the two positioning seats 5 to move closer to or away from each other, and the distance between the two positioning seats 5 is adjusted, so that the positioning mechanism can position the forged parts of different sizes and models, thereby improving the application range of the feeding device; After the positioning mechanism is adjusted, stop rotating the handle 54, and then release the pressure on the two pressing blocks 71. Under the action of the elastic force of the locking spring 73, the pressing block 71 is reset. At this time, the end of the pressing block 71 drives the locking block 72 to be clamped into the positioning groove 61 on the side of the annular block 6, so that the rotating handle 54 and the connecting block 53 cannot rotate, thereby locking the adjustment mechanism, and then the forging parts can be stably loaded.
