Description

Technical Field

[0001] The present invention relates to the technical field of feeding for forging equipment, and specifically relates to an automatic feeding mechanism for forging equipment. Background Art

[0002] Forging is the combination of forging and stamping. It is a forming processing method that uses the hammer head, anvil block, punch of forging machinery or applies pressure to the blank through a mold to make it plastically deformed, so as to obtain the workpiece with the required shape and size.

[0003] Forging equipment is mainly used for metal forming. By applying pressure to the metal to make it formed, generally, the feeding of forging equipment adopts manual feeding. Manual feeding not only has low work efficiency, but also has certain risks during the feeding process. Therefore, a feeding mechanism needs to be set on the forging equipment. The existing feeding devices of forging equipment are very inconvenient to use during the process. The existing feeding devices are only suitable for using one kind of forging equipment or one kind of forgings, thus increasing the cost of forging; and the feeding process is relatively complex and the work efficiency is not ideal; especially during the process of feeding and transporting the forgings to be forged, the stability of the material feeding cannot be guaranteed, resulting in the forgings to be forged not being accurately located directly above the mold cavity, causing the forgings to be forged to shift or misalign, thus affecting the forging effect. Summary of the Invention

[0009] Preferably, the adjusting mechanism includes a bidirectional transmission screw arranged on the side surfaces of the two positioning seats.

One end of the bearing block is in a slope shape, a lower edge strip is fixedly connected to the lower end of the slope on the bearing block, and an L-shaped transmission plate is movably inserted into one end of the L-shaped support seat.

[0013] Preferably, one end of the L-shaped drive plate passes through the L-shaped support seat and extends into the contraction groove and is fixedly connected to the side surface of the load-bearing block. The L-shaped drive plate is arranged between two return springs. On the upper end of the forging table, extrusion blocks are symmetrically and fixedly connected to both sides of the lower die. A slope is provided at the upper end of the extrusion block. The L-shaped drive plate and the extrusion block are distributed corresponding to each other vertically and horizontally.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, and has the following advantages:

[0015] 1. When feeding the workpiece to be forged, place the workpiece to be forged between the two positioning seats, and place the lower end of the workpiece to be forged on the upper end of the load-bearing block. At this time, the V-shaped positioning grooves on the side surfaces of the two positioning seats are stuck on both ends or both sides of the workpiece to be forged. The positioning of the workpiece to be forged is realized through the cooperation of the provided positioning mechanism and the load-bearing assembly.

[0016] 2. When feeding workpieces to be forged with different sizes, first separate the locking block in the locking mechanism from the positioning card slot on the side surface of the annular block. At this time, the rotary handle can be rotated arbitrarily; by rotating the rotary handle to drive the bidirectional transmission screw to rotate forward or backward, the two convex sliders approach or move away from each other, and the two positioning seats are driven by the two convex sliders to approach or move away from each other, adjusting the distance between the two positioning seats, so that the positioning mechanism can position workpieces to be forged with different sizes and models, improving the applicable range of the feeding device; after adjusting the positioning mechanism, lock the adjusting mechanism by the locking mechanism, so as to stably feed the workpiece to be forged.

[0017] 3. By rotating the output shaft of the stepping motor by half a circle, the output shaft drives the regular polygon column to rotate 180 degrees, the regular polygon column drives the rotating plate to rotate 180 degrees, the rotating plate drives the L-shaped support seats at both ends to rotate 180 degrees, and the rotating plate drives the limit card seat to rotate along the annular groove inside the annular lifting seat, so that the rotating plate can rotate stably, and the positioning mechanisms and load-bearing assemblies at both ends of the rotating plate exchange positions with each other. The workpiece to be forged is driven by the positioning mechanism and the load-bearing assembly to rotate to directly above the lower die, so as to stably move the workpiece to be forged, complete the rapid feeding of the workpiece to be forged, and there is no need for staff to manually send the workpiece to be forged into the forging equipment body, ensuring the safety of the staff.

[0018] 4. The inner rod of the hydraulic cylinder contracts downward to drive the support plate to move downward, causing the annular lifting seat to drive the rotating plate downward through the limit clamping seat. The rotating plate drives the bearing assembly and the positioning mechanism to move downward through the L-shaped support seat. At this time, the workpiece to be forged above the lower die moves downward with the bearing assembly and the positioning mechanism. At this time, the lower end of the L-shaped transmission plate in the bearing assembly slides downward along the extrusion block, causing the L-shaped transmission plate to slide outward along the L-shaped support seat. The L-shaped transmission plate drives the bearing block to move into the contraction groove. During forging, the hydraulic cylinder of the forging equipment body drives the upper die to move downward, and the upper die presses the workpiece to be forged downward. The lower end of the workpiece to be forged slides down along the slope surface of the bearing block, the side surface of the bearing block, and the lower edge strip into the cavity of the lower die. The upper die and the lower die cooperate to forge and form the workpiece to be forged. The positioning seat, bearing block, and lower edge strip ensure that the workpiece to be forged can accurately slide into the lower die, guaranteeing the forging quality of the workpiece to be forged.

[0019] 5. When forging a workpiece to be forged, feeding operation can be carried out in the positioning mechanism at the other end of the rotating plate at this time. Place the workpiece to be forged between the two positioning seats and support it through the bearing assembly. Then, the output shaft of the stepping motor rotates half a circle, and the rotating plate is driven to rotate 180 degrees by the regular polygon column, causing the positioning mechanisms and bearing assemblies at both ends of the rotating plate to exchange positions with each other. The workpiece to be forged is rotated to directly above the lower die through the positioning mechanism and the bearing assembly, waiting for the next forging operation. In this way, during the forging process of the previous workpiece to be forged, the next workpiece to be forged can be placed on the bearing assembly and clamped and fixed through the positioning mechanism at the same time, greatly improving the feeding efficiency.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 10, the present invention provides a technical solution: an automatic feeding mechanism for a forging equipment, including a forging equipment body 1 and a forging table 2. The forging table 2 is arranged below the upper die of the forging equipment body 1. A regular polygon column 22 is rotatably connected to the upper end of the forging table 2, and the regular polygon column 22 is driven by the output shaft of a stepping motor fixedly installed at the lower end of the forging table 2. One end of the top of the forging table 2 is fixedly installed with a lower die 23. The upper end of the regular polygon column 22 is sleeved with a rotating plate 3 and an annular lifting seat 4 from top to bottom in sequence. Support plates 42 are symmetrically and fixedly connected to the cylindrical surface of the annular lifting seat 4. Hydraulic cylinders 43 are symmetrically and fixedly connected to the lower ends of the support plates 42, and the hydraulic cylinders 43 are fixedly installed at the upper end of the forging table 2. Two L-shaped support seats 33 are symmetrically and fixedly connected to both ends of the rotating plate 3. A positioning mechanism for forging parts is installed between the two L-shaped support seats 33. An annular block 6 is fixedly connected to the side of one of the L-shaped support seats 33. A plurality of positioning slots 61 are arranged in an annular array on the side of the annular block 6. An adjusting mechanism for adjusting the position of the positioning mechanism is installed on the side of the annular block 6. Loading components are installed in both L-shaped support seats 33, and the two loading components are symmetrically distributed.

[0033] Please refer to Figures 2 to 5 , a regular polygon groove 31 is vertically penetrated through the upper end of the rotating plate 3, and the upper end of the regular polygon column 22 penetrates upward through the regular polygon groove 31. The regular polygon groove 31 of the rotating plate 3 is slidably connected to the regular polygon column 22 up and down.

[0034] During operation, the output shaft of the stepping motor rotates once and then stops for a period of time and then continues to rotate. In this way, the output shaft of the stepping motor rotates half a circumference each time, that is, the output shaft drives the regular polygon column 22 to rotate 180 degrees each time. The regular polygon column 22 drives the rotating plate 3 to rotate 180 degrees, and the rotating plate 3 drives the L-shaped support seats 33 at both ends to rotate half a circumference, so that the two positioning mechanisms exchange positions with each other.

[0035] The lower end of the rotating plate 3 is in rotational contact with the upper end of the annular lifting seat 4. A plurality of limit clamping seats 32 are fixedly connected to the lower end of the rotating plate 3 in an annular array. An annular groove 41 is opened inside the annular lifting seat 4. The side profile of the limit clamping seat 32 is L-shaped. The plurality of limit clamping seats 32 are annularly distributed inside the annular lifting seat 4. The protruding end on the side of the limit clamping seat 32 is clamped with the annular groove 41, and the end of the limit clamping seat 32 is rotatably connected to the annular groove 41.

[0036] The inner rod of the hydraulic cylinder 43 moves up and down to drive the support plate 42 to move up and down. The support plate 42 drives the annular lifting seat 4 to move up and down. The annular lifting seat 4 drives the rotating plate 3 to move up and down through the limit clamping seats 32. The regular polygon groove 31 on the rotating plate 3 slides up and down along the regular polygon column 22;

[0037] When the rotating plate 3 rotates, the rotating plate 3 drives the limit card seat 32 to rotate along the annular groove 41 inside the annular lifting seat 4, so that the rotating plate 3 can rotate stably, and then can move the forging workpiece to be processed stably, completing the rapid feeding of the forging workpiece to be processed, and there is no need for staff to manually send the forging workpiece to be processed into the forging equipment body 1, ensuring the safety of the staff.

[0038] Please refer to Figure 2 、 Figure 4 、 Figure 6 and Figure 9 As shown in, the positioning mechanism includes a positioning seat 5 symmetrically distributed between two L-shaped support seats 33, and convex sliders 51 symmetrically and fixedly connected to both sides of the positioning seat 5. A convex groove 34 is formed on the side surface of the L-shaped support seat 33. The two convex sliders 51 on the side surface of the positioning seat 5 are respectively slidably connected to the convex grooves 34 on the side surfaces of the two L-shaped support seats 33. V-shaped positioning grooves are formed on one side of the two positioning seats 5 close to each other.

[0039] By placing the forging workpiece to be processed between the two positioning seats 5, and clamping the two ends or two sides of the forging workpiece to be processed through the V-shaped positioning grooves on the side surfaces of the two positioning seats 5, the positioning of the forging workpiece to be processed is realized.

[0040] Please refer to Figure 6 and Figure 9 As shown in, the adjusting mechanism includes a bidirectional transmission screw 52 arranged on the side surfaces of the two positioning seats 5. Both ends of the bidirectional transmission screw 52 protrude from the rotating shaft. The bidirectional transmission screw 52 is installed in the convex groove 34 on the side surface of an L-shaped support seat 33. The bidirectional transmission screw 52 is rotatably connected to the two side walls of the convex groove 34 through the rotating shaft. Threaded holes are formed through the side surfaces of the convex sliders 51 on one side of the two positioning seats 5. The two convex sliders 51 provided with threaded holes are symmetrically sleeved on the bidirectional transmission screw 52. One end of the rotating shaft of the bidirectional transmission screw 52 sequentially passes through the inside of the L-shaped support seat 33 and the annular block 6 and is fixedly connected to the connecting block 53. A rotating handle 54 is fixedly connected to the end of the connecting block 53. Locking mechanisms are symmetrically installed on the side surface of the connecting block 53.

[0041] By rotating the rotating handle 54 to drive the bidirectional transmission screw 52 to rotate forward or backward, the rotation of the bidirectional transmission screw 52 drives the two convex sliders 51 thereon to approach or move away from each other. The two convex sliders 51 drive the two positioning seats 5 to approach or move away from each other, adjusting the distance between the two positioning seats 5, so that the positioning mechanism can position forging workpieces of different sizes and models, improving the application range of the feeding device.

[0042] Please refer to Figure 6 、 Figure 7 and Figure 10, the locking mechanism includes concave brackets 7 symmetrically and fixedly connected to the side of the connecting block 53, a pressing block 71 rotatably connected to the inside of the concave bracket 7 through a round shaft, 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 rotary handle 54. The locking block 72 is clamped with the positioning slot 61, and one end of the locking spring 73 abuts against the connecting block 53.

[0043] When the adjustment mechanism needs to adjust the positioning mechanism, it is necessary to first release the locking of the adjustment mechanism by the locking mechanism. Press the pressing ends of the two pressing blocks 71 towards the connecting block 53. The pressing ends of the pressing blocks 71 squeeze the locking spring 73. At this time, the other end of the pressing block 71 tilts up. The pressing block 71 drives the locking block 72 to separate from the positioning slot 61 on the side of the annular block 6. At this time, the rotary handle 54 can be rotated freely;

[0044] After the positioning mechanism is adjusted, stop the rotary handle 54, and then release the pressing of 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 snap into the positioning slot 61 on the side of the annular block 6, making the rotary handle 54 and the connecting block 53 unable to rotate, thereby locking the adjustment mechanism.

[0045] Please refer to Figure 3 , Figure 8 and Figure 9 , a contraction groove 35 is formed on the side of the L-shaped support base 33. The bearing assembly includes a bearing block 8 slidably connected to the contraction groove 35, and a return spring 82 symmetrically and fixedly installed on the side of the bearing block 8. 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 in a slope shape. A lower edge strip 81 is fixedly connected to the lower end of the slope on the bearing block 8. The outer side of the lower edge strip 81 and the end surface of the bearing block 8 with the slope shape are on the same side plane. The lower end surface of the lower edge strip 81 and the lower end surface of the L-shaped support base 33 are on the same horizontal plane. One end of the L-shaped support base 33 is movably inserted with an L-shaped transmission plate 83. One end of the L-shaped transmission plate 83 passes through the L-shaped support base 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 the two return springs 82. On the upper end of the forging table 2, extrusion blocks 21 are symmetrically and fixedly connected to both sides of the lower die 23. A slope is formed on the upper end of the extrusion block 21. The L-shaped transmission plate 83 and the extrusion block 21 are distributed corresponding to each other up and down.

[0046] The lower end of the positioning seat 5 is in sliding contact with the upper end of the bearing block 8. The bearing block 8 supports the workpiece to be forged. The two positioning seats 5 and the two bearing blocks 8 can cooperate to well position and support the workpiece to be forged;

[0047] When the L-shaped support base 33 moves downward, it drives the bearing assembly 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. By pushing the L-shaped transmission plate 83 through the extrusion block 21, the L-shaped transmission plate 83 slides outward along the L-shaped support base 33, and the L-shaped transmission plate 83 drives the bearing block 8 to move into the contraction groove 35;

[0048] When the lower end of the L-shaped support base 33 and the upper end of the lower die 23 are at the same horizontal plane, the downward movement of the L-shaped support base 33 is stopped. At this time, the slope surface of the bearing block 8 contacts the lower end of the workpiece to be forged. During forging, the hydraulic cylinder of the forging equipment body 1 drives the upper die to move downward, and the upper die squeezes the workpiece to be forged to move downward. The lower end of the workpiece to be forged slides downward along the slope surface of the bearing block 8. At the same time, the workpiece to be forged 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 base 33. At this time, the workpiece to be forged slides downward along the side surface of the bearing block 8 and the lower edge strip 81 into the mold cavity of the lower die 23;

[0049] The upper die and the lower die 23 cooperate to forge and form the workpiece to be forged. Through the arranged positioning seat 5, bearing block 8 and lower edge strip 81, the workpiece to be forged can accurately slide into the lower die 23, ensuring the forging quality of the workpiece to be forged.

[0050] Working principle: When it is necessary to load the workpiece to be forged, place the workpiece to be forged between the two positioning seats 5, and place the lower end of the workpiece to be forged 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 on both ends or both sides of the workpiece to be forged, and the workpiece to be forged is positioned through the cooperation of the arranged positioning mechanism and the bearing assembly;

[0051] 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 bases 33 at both ends to move upward. The L-shaped support bases 33 drive the bearing assembly and the positioning mechanism to move upward, and drive the workpiece to be forged to move upward through the bearing assembly and the positioning mechanism;

[0052] By rotating the output shaft of the stepper motor by a half circle, the output shaft drives the regular polygon column 22 to rotate 180 degrees. The regular polygon 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 inside the annular lifting seat 4, so that the rotating plate 3 can rotate stably, enabling the positioning mechanisms and the bearing components at both ends of the rotating plate 3 to exchange positions with each other. The positioning mechanisms and the bearing components drive the workpiece to be forged to rotate above the lower die 23, and then the workpiece to be forged can be stably moved, completing the rapid feeding of the workpiece to be forged, and there is no need for staff to manually send the workpiece to be forged into the forging equipment body 1, ensuring the safety of the staff.

[0053] By the inner rod of the hydraulic cylinder 43 contracting downward, the support plate 42 is driven to move downward. 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. The rotating plate 3 drives the bearing components and the positioning mechanisms to move downward through the L-shaped support seats 33. At this time, the workpiece to be forged above the lower die 23 moves downward along with the bearing components and the positioning mechanisms.

[0054] At this time, the lower end of the L-shaped transmission plate 83 in the bearing component first contacts the upper end of the extrusion block 21. By the continuous contraction of the inner rod of the hydraulic cylinder 43, the L-shaped transmission plate 83 slides downward along the extrusion block 21. The extrusion block 21 is used to push 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.

[0055] When the lower end of the L-shaped support seat 33 is at the same horizontal plane as the upper end of the lower die 23, the L-shaped support seat 33 stops moving downward. Under the action of the gravity of the workpiece to be forged, at this time, the slope surface of the bearing block 8 contacts the lower end of the workpiece to be forged. During forging, the hydraulic cylinder of the forging equipment body 1 drives the upper die to move downward. The upper die squeezes the workpiece to be forged to move downward. The lower end of the workpiece to be forged slides downward along the slope surface of the bearing block 8. At the same time, the workpiece to be forged 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 workpiece to be forged slides downward along the side surface of the bearing block 8 and the lower edge strip 81 into the die cavity of the lower die 23.

[0056] The upper die and the lower die 23 cooperate to forge and form the workpiece to be forged. By setting the positioning seat 5, the bearing block 8 and the lower edge strip 81, the workpiece to be forged can accurately slide into the lower die 23, ensuring the forging quality of the workpiece to be forged.

[0057] When performing a forging operation on a forging workpiece to be processed, at this time, a feeding operation can be carried out inside the positioning mechanism at the other end of the rotating plate 3, and the forging workpiece to be processed is placed between the two positioning seats 5 and supported by the bearing assembly.

[0058] After the forging is completed, the upper die of the forging equipment body 1 moves upward to reset. At this time, the inner rod of the hydraulic cylinder 43 extends upward, causing the rotating plate 3 to drive the bearing assemblies and positioning mechanisms at both ends upward, so that the lower end of the L-shaped transmission plate 83 in the bearing assembly moves away from the extrusion block 21. Under the action of the elastic force of the return spring 82, the bearing block 8 moves outward along the contraction groove 35, so that the bearing block 8 resets and waits for the feeding of the next forging workpiece to be processed;

[0059] At this time, the output shaft of the stepping motor rotates by a half circle again, and the rotating plate 3 is driven to rotate by 180 degrees through the regular polygon column 22, so that the positioning mechanisms and bearing assemblies at both ends of the rotating plate 3 exchange positions with each other, and the forging workpiece to be processed is rotated to directly above the lower die 23 through the positioning mechanism and the bearing assembly, waiting for the next forging operation. In this way, during the forging process of the previous forging workpiece to be processed, the next forging workpiece to be processed can be placed on the bearing assembly at the same time and clamped and fixed by the positioning mechanism, greatly improving the feeding efficiency.

[0060] When feeding forging workpieces of different sizes, press the two pressing blocks 71. The pressing ends of the pressing blocks 71 squeeze the locking spring 73. At this time, the other ends of the pressing blocks 71 drive the locking blocks 72 to separate from the positioning slots 61 on the side of the annular block 6, and at this time, the rotating handle 54 can be rotated arbitrarily;

[0061] By rotating the rotating handle 54 to drive the bidirectional transmission screw 52 to rotate forward or backward, the two convex sliders 51 approach or move away from each other. The two convex sliders 51 drive the two positioning seats 5 to approach or move away from each other, adjusting the distance between the two positioning seats 5, so that the positioning mechanism can position forging workpieces of different sizes and models, improving the application range of the feeding device;

[0062] After the positioning mechanism is adjusted, stop rotating the rotating handle 54, and then release the pressing of the two pressing blocks 71. Under the action of the elastic force of the locking spring 73, the pressing blocks 71 reset. At this time, the ends of the pressing blocks 71 drive the locking blocks 72 to snap into the positioning slots 61 on the side of the annular block 6, making the rotating handle 54 and the connecting block 53 unable to rotate, thus locking the adjusting mechanism, and further being able to stably feed the forging workpiece to be processed.

[0063] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
