Description

Technical Field

[0001] The present invention relates to the technical field of elevator bolt processing equipment, and particularly to an automatic forging and pressing processing device for elevator bolts. Background Technique

[0002] Elevator bolt forging and pressing equipment is a key equipment for manufacturing and processing elevator bolts. When shaping the head of the elevator bolt, the forging and pressing equipment mainly works based on the principle of metal plastic forming. By applying an external force, plastic deformation occurs in the upper part of the elevator bolt blank, so as to obtain the required shape and size. This step is crucial for the overall quality and performance of the elevator bolt. Through forging and pressing, the head of the bolt can reach the required shape and size accuracy, and at the same time, the density and strength of the bolt head are improved, thereby improving the subsequent service life of the elevator bolt.

[0003] In the prior art, such as a continuous forging press for bolt production disclosed in the publication number: CN116140538B, which includes an installation frame, a support frame, a hydraulic cylinder, a forging upper die, a forging lower die, a rotating mechanism, etc. The installation frame is connected with a support frame, the support frame is connected with a hydraulic cylinder, the telescopic rod of the hydraulic cylinder is connected with a forging upper die for forming the bolt blank, the installation frame is connected with a forging lower die for forming the bolt blank, and a rotating mechanism is arranged on the installation frame. The conveyor of the present invention can automatically convey the bolt blank to the rotating disk to the right, control the reduction motor to drive the rotating disk and the arc rack to rotate intermittently, and the pressing plate can automatically press the bolt blank into the feeding hole to improve work efficiency. Then, control the hydraulic cylinder to drive the forging upper die to push the bolt blank into the forging lower die for forging. The positioning rod will be stuck in the positioning groove, thereby positioning the rotating disk and improving the accuracy of the forging direction.

[0004] Although the above equipment can perform automatic forging and pressing operations on the bolt blank, when the above bolt forging and pressing equipment performs feeding and positioning on the bolt, it needs a motor to drive the gear for transmission to complete the feeding, resulting in deficiencies in the convenience of feeding the bolt blank and the stability of guiding the blank. At the same time, the linkage between the feeding equipment and the forging and pressing equipment in the above equipment is poor, thereby increasing the bottleneck time of the equipment for the conversion process, thus increasing the overall time for the equipment to perform forging and pressing processing on the bolt blank and reducing the processing efficiency. Therefore, an automatic forging and pressing processing device for elevator bolts is needed to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic forging and pressing processing device for elevator bolts to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: An automatic forging and pressing processing device for elevator bolts, including a blanking slide seat for support, a feeding device for guiding is fixedly arranged on the upper end surface of the blanking slide seat, a fixed clamping seat for support is fixedly arranged at the center of the upper end surface of the feeding device, and a reduction motor is fixedly arranged at the center of the upper end surface of the fixed clamping seat.

The lower end surface of the first gear is meshed with the transmission device through a second gear, and the transmission device is meshed with the feeding device through a first synchronous belt. The transmission device and the feeding device are synchronously driven by the first synchronous belt. By setting the transmission device and the feeding device to follow each other, the processing efficiency of elevator bolt blanks without interruption can be improved.

[0009] A forging and pressing device, the forging and pressing device is elastically and slidably clamped at the inner end surface of the fixed clamping seat through the fixed clamping seat. A feeding device is arranged on the front end surface of the fixed clamping seat, and elevator bolt blanks are equidistantly slidably connected at the inner end surface of the feeding device. The feeding device can store and guide multiple groups of elevator bolt blanks, facilitating subsequent continuous supply of raw materials into the feeding device for forging and pressing.

[0010] Preferably, the feeding device includes a support clamping frame for docking and positioning. A fixed clamping frame is fixedly arranged at the rear end surface of the support clamping frame, and four groups of feeding sliding cylinders are equidistantly arranged at the inner end surface of the fixed clamping frame. Observation guide grooves are opened on the outer end surface of each group of the feeding sliding cylinders. Alignment sliding seats are arranged at the bottom openings of the feeding sliding cylinders directly opposite to the lower end surface of the fixed clamping frame. The alignment sliding seats are used to fit the side walls of the transmission rotating seats, thereby feeding the elevator bolt blanks inside the feeding sliding cylinders one by one. The observation guide grooves can not only facilitate the staff to observe the quantity of elevator bolt blanks in real time but also facilitate subsequent dredging of the stuck elevator bolt blanks, improving the practicability of the equipment.

[0011] Preferably, the transmission device includes a fixed guide shaft for transmission. At both ends of the side of the fixed guide shaft, first synchronous belt pulleys are provided, and third gears are provided inside both ends of the side of the fixed guide shaft. Four groups of forging cams are equidistantly arranged on the outer end face of the fixed guide shaft. The forging cam consists of two parts, an upper part with a large radius and a lower part with a small radius. The guiding mode of the cam can effectively improve the stability of the forging device for forging elevator bolt blanks.

[0012] Preferably, the feeding device includes two supporting side plates for support. In the middle of the inner end faces of the two supporting side plates, a driving shaft for transmission is provided. Four groups of limiting devices are equidistantly arranged on the outer end face of the driving shaft. At both ends of the side of the driving shaft, cam turntables are provided. Six groups of limiting rotating grooves are equidistantly opened on the outer end face of the cam turntable. Positioning sliding grooves are opened on the inner end face of the cam turntable opposite to the adjacent two limiting rotating grooves. At the upper parts of the cam turntables, the outer end faces of the two supporting side plates are rotatably clamped with notch chucks. At the center of the upper end face of the notch chuck, a limiting dial rod is fixedly provided. At the center of the side end face of the notch chuck, a second synchronous belt pulley is fixedly provided. A second synchronous belt pulley is provided on the outer end face of the driving shaft near the cam turntable. At the front part of the inner end face of the supporting side plate, a deflecting device for closing is provided. At the bottom of the front end faces of the two supporting side plates, a transmission guide roller is rotatably clamped. At the side end face of the transmission guide roller near the second synchronous belt pulley, a third synchronous belt pulley is provided. The second synchronous belt pulley and the third synchronous belt pulley are meshed and connected by a second synchronous belt. A cam sliding groove is opened on the outer end face of the transmission guide roller. A guiding device is slidably clamped on the outer end face of the transmission guide roller through the cam sliding groove. The guiding device can drive the falling elevator bolt blanks to be automatically and quickly exported above the blanking slide seat under the drive of the cam sliding groove, improving the blanking efficiency. The intermittent transmission mode between the notch chuck and the cam turntable enables the notch chuck to lock the cam turntable through the limiting rotating groove when the forging device moves down for forging, thereby providing time for the forging device to forge the elevator bolt blanks. At the same time, after the forging device finishes forging, the notch chuck drives the cam turntable and the limiting device to rotate and feed materials through the limiting dial rod, effectively improving the efficiency of the equipment for forging and guiding the elevator bolt blanks;

[0013] The forging device includes a forging clamping seat. At least four groups of positioning baffles are equidistantly arranged on the upper end surface of the forging clamping seat, and four groups of forging punch shafts are equidistantly arranged on the lower end surface of the forging clamping seat. Support springs are fixedly arranged at the coaxial centers of the lower end surface of the forging clamping seat and the forging punch shafts. An internal hexagonal forging die is fixedly installed at the bottom end surface of the forging punch shaft, and positioning clamping shafts are equidistantly arranged outside the lower end surface of the internal hexagonal forging die. The positioning clamping shafts can quickly and accurately position the elevator bolt blank inside the forging bottom die, improving the stability of limiting the elevator bolt blank.

[0014] Preferably, the deflecting device includes an arc-shaped sliding plate for limiting and supporting. Four groups of limiting brackets are equidistantly arranged on the inner end surface of the arc-shaped sliding plate, and positioning clamping seats are fixedly arranged at the end heads of the inner end surfaces of the limiting brackets. A guiding deflecting plate is arranged at the bottom of the side end surface of the positioning clamping seat. The guiding deflecting plate is arranged in an inclined shape, and a fillet is arranged at its bottom, which is convenient for quick reset operation after the guiding of the fixed guide rod is completed. The positioning clamping seat is arranged in a disc shape, which can conveniently perform sliding limit on the end of the fixed guide rod, improving the stability of the guiding displacement of the subsequent fixed guide rod.

[0015] The limiting device includes a transmission rotating seat. At least six groups of fixed clamping grooves are equidistantly opened on the side end surface of the transmission rotating seat. A forging bottom die is fixedly clamped in the inner end surface of the fixed clamping groove. At least six groups of positioning guide grooves are equidistantly opened on the upper end surface of the forging bottom die. Positioning slots for limiting are symmetrically opened on the lower end surface of the forging bottom die. A top-out device is equidistantly arranged at the inner end surface of the transmission rotating seat corresponding to the forging bottom die. The top-out device can not only lock and limit the elevator bolt blank, but also guide and top out the elevator bolt blank, improving the stability of subsequent feeding and the convenience of discharging of the elevator bolt blank. Chamfers for positioning are opened at the front parts of the positioning guide grooves, which is convenient for the quick insertion and positioning of the subsequent positioning clamping shafts.

[0016] The guiding device includes a fixed clamping sleeve for guiding. A support sliding shaft is fixedly arranged at the top of the inner end surface of the fixed clamping sleeve, and a blanking guide plate is fixedly arranged at the lower end surface of the fixed clamping sleeve.

[0017] Preferably, the ejecting device includes a supporting guide plate, on the upper end face of which a clamping guide seat is fixedly arranged. Two spring clamps are elastically and slidably clamped on the inner end face of the clamping guide seat. A guiding slide seat is slidably clamped on the inner end face of the supporting guide plate. A fixed guide rod is fixedly arranged at the center of the side end face of the guiding slide seat, and an ejecting guide shaft is fixedly arranged at the center of the upper end face of the guiding slide seat. Return springs are symmetrically arranged on the upper end face of the guiding slide seat with the ejecting guide shaft as the center, which is convenient for providing sufficient elastic force for the ejection and reset of the ejecting guide shaft in the subsequent process. The ejecting guide shaft can cooperate with the two return springs, which is convenient for ejecting and guiding the elevator bolt blanks locked inside the forging bottom die in the subsequent process. The spring clamp includes a locking clamp for clamping and a connecting spring arranged at the rear of the locking clamp. In the initial state of the spring clamp, it can protrude from the inside of the forging bottom die through the positioning slot, which is convenient for the locking clamp to provide sufficient locking and clamping elastic force for the elevator bolt blank after the elevator bolt blank falls into the forging bottom die, improving the stability of the subsequent guiding of the elevator bolt blank.

[0018] Preferably, the first gear is meshed and connected with the third gear through the second gear. The elevator bolt blanks are equidistantly slidably connected inside the fixed bracket through the material guiding slide cylinder. The alignment slide seat is attached to the outer end face of the transmission rotating seat. The elevator bolt blanks can be introduced into the upper part of the transmission rotating seat through the material guiding slide cylinder. At the same time, since the alignment slide seat is attached to the side part of the transmission rotating seat, it is convenient for the side wall of the transmission rotating seat and the alignment slide seat to form a limiting structure in the subsequent process, so that the elevator bolt blanks can be introduced into the forging bottom die one by one.

[0019] Preferably, the first synchronous pulley is meshed and connected with the second synchronous pulley through the first synchronous belt. The notch chuck is rotationally clamped with the cam turntable through the limiting rotating groove. And the notch chuck is intermittently rotationally connected with the cam turntable through the limiting dial rod and the positioning chute being adapted to each other. The notch chuck and the limiting dial rod can drive the cam turntable to rotate intermittently by a certain degree through the limiting rotating groove and the positioning chute, which is convenient for the subsequent limiting device to cooperate with the forging of the forging device to perform non-stop feeding operation at the bottom of the forging device, improving the processing efficiency of the elevator bolt blanks in the subsequent process. The second synchronous pulley can provide intermittent power for the cam turntable, which is convenient for driving the limiting device to perform intermittent feeding at the bottom of the forging device in the subsequent process.

[0020] Preferably, the blanking guide plate is reciprocally slidably connected to the upper end surface of the blanking slide base through the support sliding shaft adapted to the cam chute. The elevator bolt blank is elastically fixed and clamped inside the forging bottom die through two groups of spring clamps. The fixed guide rod is elastically slidably connected to the guiding deflector. The outer end surface of the transmission rotating base is in fitting connection with the inner wall of the arc-shaped slide plate. When the fixed guide rod rotates circumferentially to the bottommost position, it can be in fitting and guiding connection with the guiding deflector. When the guiding deflector continues to rotate as the fixed guide rod rotates, it can drive the fixed guide rod to move down to the bottommost position, facilitating the ejection and blanking of the elevator bolt blank. When the limiting device intermittently feeds the elevator bolt blank, the drive shaft driving the limiting device can synchronously drive the transmission guide roller and the cam chute to rotate through the second synchronous pulley, the second synchronous belt, and the third synchronous pulley, so that the blanking guide plate can displace back and forth inside the blanking slide base to perform cyclic blanking on the elevator bolt blank. Guide material round corners are provided at both the top and the bottom of the spring clamp, facilitating the feeding and positioning of the subsequent elevator bolt blank.

[0021] Preferably, the outer end surface of the forging cam is elastically and fittingly connected to the forging clamping seat through the positioning baffle. The forging punching shaft and the forging bottom die are coaxially arranged. The internal hexagonal forging die is fixedly clamped to the upper end surface of the forging bottom die through the positioning clamping shaft adapted to the positioning guide groove, effectively improving the stability of pre-positioning and limiting the elevator bolt blank during forging when the internal hexagonal forging die moves down subsequently. The positioning baffle can limit the side part of the forging cam, improving the stability of guiding the forging cam to press and fit the forging clamping seat subsequently.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The present invention is a high-speed non-stop processing mechanism. The feeding device can sequentially introduce multiple groups of elevator bolt blanks into the internal part of the material guiding device through gravity spring clips for feeding. At the same time, the transmission device, the material guiding device, and the forging device can operate synchronously, enabling the material guiding device to feed while the transmission device drives the forging device to forge the elevator bolt blanks fed by the material guiding device, effectively improving the stability and accuracy of the equipment for feeding the elevator bolt blanks, and also improving the forging processing efficiency of the equipment for the elevator bolt blanks.

[0024] 2. When the present invention is in transmission, the reduction motor can synchronously provide power for the transmission device and the feeding device through the first bevel gear, the second bevel gear, the transmission card shaft, the first gear and the second gear. The transmission device can synchronously forge the elevator bolt blanks fed intermittently to the feeding device by the forging device. At the same time, the feeding device can automatically discharge the forged elevator bolt blanks to the upper part of the blanking slide seat through a rotary structure, effectively improving the stability of the linkage between devices, reducing the bottleneck time of each process of the device, improving the utilization efficiency of power by the device, and reducing the processing cost of the elevator bolt blanks.

[0025] 3. When the present invention discharges the forged elevator bolt blanks, the intermittent rotation of the transmission turntable can drive the fixed guide rod and the guiding dial plate to slide and limit one by one, so that the guiding dial plate can drive the ejecting guide shaft through the fixed guide rod to eject the two groups of limited elevator bolt blanks, effectively improving the stability of the device for discharging and guiding the elevator bolt blanks. At the same time, when the transmission turntable rotates, it can synchronously provide power for the transmission guide roller, so that the transmission guide roller can drive the blanking guide plate to reciprocate on the upper part of the blanking slide seat through the cooperation of the cam chute and the support slide shaft, facilitating the quick and convenient discharge of the discharged elevator bolt blanks, and further improving the convenience for the staff to collect the elevator bolt blanks subsequently.

[0047] The present invention will be further described below with reference to the drawings.

[0048] Embodiment 1

[0049] Please refer to Figure 1-17 , an embodiment provided by the present invention: an automatic forging and pressing processing device for elevator bolts, including a blanking slide base 13 for support, a feeding device 4 for guiding materials is fixedly arranged on the upper end surface of the blanking slide base 13, and a fixed clamping seat 8 for support is fixedly arranged at the center of the upper end surface of the feeding device 4, and a reduction motor 9 is fixedly arranged at the center of the upper end surface of the fixed clamping seat 8. A first bevel gear 14 is fixedly arranged at the output end of the reduction motor 9.

[0050] A transmission card shaft 6, the transmission card shaft 6 is rotationally clamped at the top of the inner end surface of the fixed clamping seat 8 through two groups of limit rotating seats 7, and a second bevel gear 15 meshing with the first bevel gear 14 is arranged near the middle of the outer end surface of the transmission card shaft 6. First gears 10 are arranged at both ends of the side part of the transmission card shaft 6. During transmission, the reduction motor 9 can drive the transmission card shaft 6 and two groups of first gears 10 to rotate synchronously through the first bevel gear 14 and the second bevel gear 15, so that the two groups of first gears 10 can provide power for the transmission device 3 through the second gear 11, improving the efficiency of subsequent forging of elevator bolt blanks 1.

[0051] A transmission device 3, the transmission device 3 is rotationally clamped at the middle part of the inner end surface of the fixed clamping seat 8. The lower end surface of the first gear 10 is meshed with the transmission device 3 through a second gear 11, and the transmission device 3 is meshed with the feeding device 4 through a first synchronous belt 12. The transmission device 3 and the feeding device 4 are synchronously driven through the first synchronous belt 12. By setting the transmission device 3 and the feeding device 4 to follow each other, the processing efficiency of the elevator bolt blank 1 without interruption can be improved.

[0052] The forging device 5 is elastically and slidably clamped to the inner end face of the fixed clamping seat 8 through the fixed clamping seat 8. The front end face of the fixed clamping seat 8 is provided with a feeding device 2, and a plurality of elevator bolt blanks 1 are slidably connected at equal intervals to the inner end face of the feeding device 2. The feeding device 2 can store and guide multiple groups of elevator bolt blanks 1, facilitating the subsequent continuous supply of raw materials to the inside of the feeding device 4 for forging.

[0053] As Figure 5 , the feeding device 2 includes a support bracket 25 for docking and positioning. The rear end face of the support bracket 25 is fixedly provided with a fixed bracket 22, and four guide material sliding cylinders 23 are arranged at equal intervals on the inner end face of the fixed bracket 22. Observation guide grooves 24 are formed on the outer end faces of each group of guide material sliding cylinders 23. The observation guide grooves 24 can not only facilitate the staff to observe the quantity of elevator bolt blanks 1 in real time but also facilitate the subsequent dredging of the stuck elevator bolt blanks 1, improving the practicability of the equipment. Alignment sliding seats 21 are arranged at the bottom openings of the guide material sliding cylinders 23 directly below the lower end face of the fixed bracket 22. The alignment sliding seats 21 are used to fit the side walls of the transmission rotating seats 436, thereby feeding the elevator bolt blanks 1 inside the guide material sliding cylinders 23 one by one.

First synchronous belt wheels 31 are arranged at both ends of the side part of the fixed guide shaft 34, and third gears 32 are arranged inside both ends of the side part of the fixed guide shaft 34. Four forging cams 33 are arranged at equal intervals on the outer end face of the fixed guide shaft 34. The forging cams 33 are composed of two parts, an upper part with a large radius and a lower part with a small radius. The guiding mode of the cams can effectively improve the stability of the forging device 5 in forging the elevator bolt blanks 1.

[0055] As Figures 7-10, the material guiding device 4 includes two groups of supporting side plates 412 for support. In the middle of the inner end faces of the two groups of supporting side plates 412, a driving shaft 416 for transmission is provided. Four groups of limiting devices 43 are equidistantly arranged on the outer end face of the driving shaft 416. Cam turntables 47 are arranged at both ends of the side part of the driving shaft 416. Six groups of limiting rotating grooves 413 are equidistantly formed on the outer end face of the cam turntable 47. Positioning sliding grooves 415 are formed on the inner end face of the cam turntable 47 opposite to the adjacent two groups of limiting rotating grooves 413. At the upper parts of the outer end faces of the two groups of supporting side plates 412 opposite to the cam turntable 47, notch chucks 414 are rotatably clamped. At the center of the upper end face of the notch chuck 414, a limiting shifting rod 45 is fixedly arranged. The intermittent transmission mode between the notch chuck 414 and the cam turntable 47 enables the notch chuck 414 to lock the cam turntable 47 through the limiting rotating groove 413 when the forging device 5 moves downward for forging, thereby providing time for the forging device 5 to forge the elevator bolt blank 1. At the same time, after the forging device 5 finishes forging, the notch chuck 414 drives the cam turntable 47 and the limiting device 43 to rotate for feeding through the limiting shifting rod 45, effectively improving the efficiency of the equipment for forging and guiding the elevator bolt blank 1. At the center of the side end face of the notch chuck 414, a second synchronous pulley 46 is fixedly arranged. A second synchronous pulley 48 is arranged on the outer end face of the driving shaft 416 near the cam turntable 47. A deflecting device 42 for closing is arranged at the front part of the inner end face of the supporting side plate 412. A transmission guide roller 411 is rotatably clamped at the bottom of the front end faces of the two groups of supporting side plates 412. A third synchronous pulley 49 is arranged on the side end face of the transmission guide roller 411 near the second synchronous pulley 46. The second synchronous pulley 48 and the third synchronous pulley 49 are meshed and connected through a second synchronous belt 410. A cam sliding groove 41 is formed on the outer end face of the transmission guide roller 411. A guiding device 44 is slidably clamped on the outer end face of the transmission guide roller 411 through the cam sliding groove 41. The guiding device 44 can automatically and quickly export the falling elevator bolt blank 1 above the blanking slide base 13 under the drive of the cam sliding groove 41, improving the blanking efficiency;

[0056] As Figure 17 , the forging device 5 includes a forging clamping seat 52. At least four groups of positioning baffles 51 are equidistantly arranged on the upper end face of the forging clamping seat 52. Four groups of forging punching shafts 55 are equidistantly arranged on the lower end face of the forging clamping seat 52. Support springs 56 are fixedly arranged at the coaxial centers of the lower end face of the forging clamping seat 52 and the forging punching shafts 55. An internal hexagonal forging die 53 is fixedly installed on the bottom end face of the forging punching shaft 55. Positioning clamping shafts 54 are equidistantly arranged outside the lower end face of the internal hexagonal forging die 53. The positioning clamping shafts 54 can quickly and accurately position the elevator bolt blank 1 inside the forging bottom die 434, improving the stability of limiting the elevator bolt blank 1.

[0057] As Figure 11, the dialing device 42 includes an arc-shaped slide plate 422 for limiting and supporting. Four groups of limiting brackets 421 are equidistantly arranged on the inner end face of the arc-shaped slide plate 422. A positioning seat 424 is fixedly arranged at the end of the inner end face of the limiting bracket 421. The positioning seat 424 is arranged in a disc shape, which can facilitate the sliding limit of the end of the fixed guide rod 4324 and improve the stability of the subsequent guiding displacement of the fixed guide rod 4324. A guiding dial 423 is arranged at the bottom of the side end face of the positioning seat 424. The guiding dial 423 is arranged in an inclined shape, and its bottom is provided with a rounded corner, which is convenient for the subsequent quick reset operation after the guiding of the fixed guide rod 4324 is completed;

[0058] As Figure 12 and Figure 13 , the limiting device 43 includes a transmission rotating seat 436. At least six groups of fixed chucks 431 are equidistantly opened on the side end face of the transmission rotating seat 436. A forging bottom die 434 is fixedly clamped on the inner end face of the fixed chuck 431. At least six groups of positioning guide grooves 435 are equidistantly opened on the upper end face of the forging bottom die 434. Chamfers for positioning are opened at the front parts of the positioning guide grooves 435, which is convenient for the quick insertion and positioning of the subsequent positioning card shaft 54. Positioning slots 433 for limiting are symmetrically opened on the lower end face of the forging bottom die 434. A jacking device 432 is equidistantly arranged on the inner end face of the transmission rotating seat 436 opposite to the forging bottom die 434. The jacking device 432 can not only lock and limit the elevator bolt blank 1, but also guide and eject the elevator bolt blank 1, which can improve the stability of the subsequent feeding of the elevator bolt blank 1 and the convenience of discharging;

[0059] As Figure 16 , the guiding device 44 includes a fixed bushing 442 for guiding. A support sliding shaft 441 is fixedly arranged at the top of the inner end face of the fixed bushing 442. A blanking guide plate 443 is fixedly arranged at the lower end face of the fixed bushing 442.

[0060] As Figure 14 and Figure 15, the ejection device 432 includes a support guide plate 4321. A clamping guide seat 4327 is fixedly arranged on the upper end surface of the support guide plate 4321. Two sets of spring clamps 4326 are elastically slidably clamped on the inner end surface of the clamping guide seat 4327. The spring clamp 4326 includes a locking clamp for clamping and a connecting spring arranged at the rear of the locking clamp. In the initial state, the spring clamp 4326 can protrude from the inside of the forging bottom die 434 through the positioning slot 433. After the elevator bolt blank 1 falls into the forging bottom die 434 subsequently, the locking clamp can provide sufficient locking and clamping elastic force for the elevator bolt blank 1, improving the stability of the subsequent guiding of the elevator bolt blank 1. A guiding slide seat 4323 is slidably clamped on the inner end surface of the support guide plate 4321. A fixed guide rod 4324 is fixedly arranged at the center of the side end surface of the guiding slide seat 4323. A top ejection guide shaft 4322 is fixedly arranged at the center of the upper end surface of the guiding slide seat 4323. The top ejection guide shaft 4322 can cooperate with two sets of return springs 4325, facilitating the subsequent top ejection and guiding of the elevator bolt blank 1 locked inside the forging bottom die 434. The return springs 4325 are symmetrically arranged on the upper end surface of the guiding slide seat 4323 with the top ejection guide shaft 4322 as the center, facilitating the subsequent provision of sufficient elastic force for the top ejection and reset of the top ejection guide shaft 4322.

[0061] As Figure 4 , the first gear 10 is meshed and connected with the third gear 32 through the second gear 11, which can effectively improve the stability of the subsequent transmission between devices. The elevator bolt blank 1 is equidistantly slidably connected inside the fixed bracket 22 through the material guiding slide cylinder 23. The alignment slide seat 21 is in fit connection with the outer end surface of the transmission rotating seat 436. The elevator bolt blank 1 can be introduced into the upper part of the transmission rotating seat 436 through the material guiding slide cylinder 23. At the same time, due to the fit connection between the alignment slide seat 21 and the side part of the transmission rotating seat 436, it is convenient to form a limiting structure between the side wall of the subsequent transmission rotating seat 436 and the alignment slide seat 21, enabling the elevator bolt blank 1 to be introduced into the forging bottom die 434 one by one.

[0062] As Figure 6 and Figure 9, the first synchronous pulley 31 is meshed and connected to the second synchronous pulley 46 through the first synchronous belt 12. The second synchronous pulley 46 can provide intermittent power for the cam turntable 47, facilitating subsequent driving of the limiting device 43 to intermittently feed the bottom of the forging device 5. The notch chuck 414 is rotationally clamped to the cam turntable 47 through the limiting rotating groove 413, and the notch chuck 414 is adapted to the positioning sliding groove 415 through the limiting lever 45, thereby driving the cam turntable 47 to be intermittently rotationally connected. The notch chuck 414 and the limiting lever 45 can drive the cam turntable 47 to intermittently rotate by 60 degrees through the limiting rotating groove 413 and the positioning sliding groove 415, which can facilitate subsequent cooperation between the limiting device 43 and the forging of the forging device 5, and perform non-stop feeding operation on the bottom of the forging device 5, improving the efficiency of subsequent processing of the elevator bolt blank 1.

[0063] As Figure 9 and Figure 16 , the blanking guide plate 443 is reciprocally slidably connected to the upper end surface of the blanking slide base 13 through the support sliding shaft 441 and being adapted to the cam sliding groove 41. When the limiting device 43 intermittently feeds the elevator bolt blank 1, the driving shaft 416 of the driving limiting device 43 can synchronously drive the transmission guide roller 411 and the cam sliding groove 41 to rotate through the second synchronous pulley 48, the second synchronous belt 410, and the third synchronous pulley 49, thereby enabling the blanking guide plate 443 to displace back and forth inside the blanking slide base 13 to perform cyclic blanking on the elevator bolt blank 1. The elevator bolt blank 1 is elastically fixed and clamped inside the forging bottom die 434 through two groups of spring clamps 4326. Guide material round corners are provided at the top and bottom of the spring clamps 4326 to facilitate subsequent feeding and positioning of the elevator bolt blank 1. The fixed guide rod 4324 is elastically slidably connected to the guiding dial 423, and the outer end surface of the transmission rotating seat 436 is in fit connection with the inner wall of the arc-shaped slide plate 422. When the fixed guide rod 4324 rotates circumferentially to the bottommost position, it can be in fit and guiding connection with the guiding dial 423. When the guiding dial 423 continues to rotate with the fixed guide rod 4324, it can drive the fixed guide rod 4324 to move down to the bottommost position to facilitate ejecting and blanking of the elevator bolt blank 1.

[0064] As Figure 17 , the outer end surface of the forging cam 33 is elastically in fit connection with the forging clamping seat 52 through the positioning baffle 51. The positioning baffle 51 can limit the side of the forging cam 33, improving the stability of subsequent press-fitting and guiding of the forging cam 33 to the forging clamping seat 52. The forging punch shaft 55 and the forging bottom die 434 are coaxially arranged, and the internal hexagonal forging die 53 is fixedly clamped to the upper end surface of the forging bottom die 434 through the positioning card shaft 54 and being adapted to the positioning guide groove 435, which can effectively improve the stability of pre-positioning and limiting of the elevator bolt blank 1 during forging when the internal hexagonal forging die 53 moves down for forging.

[0065] Working principle: Before use, the staff can import multiple groups of elevator bolt blanks 1 to be forged into the internal part of the feeding device 2 through an external robotic arm, which facilitates the subsequent continuous feeding of the feeding device 2. At the same time, starting the reduction motor 9 can provide power for subsequent forging, thereby improving the efficiency of forging and processing the elevator bolt blanks 1. When forging and feeding the elevator bolt blanks 1, as Figure 1 and Figure 7 , under the action of gravity, multiple groups of elevator bolt blanks 1 inside the material guiding sliding cylinder 23 can move downward. Since the positioning sliding seat 21 fits with the outer circumference of the driving rotating seat 436, and at the same time the forging bottom die 434 is coaxially aligned with the bottom of the material guiding sliding cylinder 23, when the above-mentioned driving rotating seat 436 drives the forging bottom die 434 to rotate intermittently to the bottom of the material guiding sliding cylinder 23, at this time the material guiding sliding cylinder 23 can directly position the elevator bolt blanks 1 inside it into the forging bottom die 434, as Figure 13 and Figure 14 . When the elevator bolt blanks 1 are introduced into the forging bottom die 434 under the action of gravity, at this time the two spring clamps 4326 inside the positioning slot 433 move centrifugally towards both sides under the action of the gravity of the elevator bolt blanks 1. When the elevator bolt blanks 1 are completely positioned inside the forging bottom die 434, at this time the two spring clamps 4326 can limit and fix the screw of the elevator bolt blanks 1 through elastic force, preventing the subsequent elevator bolt blanks 1 from shifting during material guiding or processing. When the feeding of the elevator bolt blanks 1 is completed, at this time the reduction motor 9 continuously provides power output, as Figure 2 and Figure 4 , the reduction motor 9 can drive the transmission card shaft 6 to rotate through the meshing of the first bevel gear 14 and the second bevel gear 15. At the same time, the transmission card shaft 6 can synchronously drive the two first gears 10 at the end to rotate, so that the first gears 10 can synchronously drive the two third gears 32 to rotate through the second gears 11. The third gears 32 can then synchronously drive the forging cam 33 and the first synchronous pulley 31 to rotate through the fixed guide shaft 34, as Figure 7When the elevator bolt blank 1 that has been loaded is guided, the first synchronous pulley 31 can synchronously drive the second synchronous pulley 46 to mesh and rotate through the first synchronous belt 12, and the second synchronous pulley 46 can synchronously drive the notched chuck 414 and the positioning slide groove 415 to rotate in a circle. When the limit lever 45 can pass through the sliding limit with the positioning slide groove 415, it can drive the cam turntable 47 to rotate 60 degrees, and the cam turntable 47 can drive the transmission swivel seat 436 to rotate one station, so that the elevator bolt blank 1 that has just been loaded can be directly positioned directly below the forging device 5. When the positioning slide groove 415 has completed the cam turntable 47 through the limit lever 45, the notched chuck 414 can pass through the limit lever 45 to move the cam turntable 47. The rotation of the rotating groove 413 locks the cam rotating disk 47, thereby providing sufficient limiting basis and time for the subsequent forging device 5 to forge the elevator bolt blank 1. When the elevator bolt blank 1 is guided, the third gear 32 and the forging cam 33 can rotate synchronously, and at the same time, the outer edge of the cam with a smaller diameter of the forging cam 33 fits with the upper part of the forging clamp 52. When the transmission rotating seat 436 drives the elevator bolt blank 1 to be positioned to the bottom of the forging device 5, the outer edge of the large radius of the forging cam 33 begins to be pressed with the top of the forging clamp 52. The forging clamp 52 moves downward under the rigid pressing of the forging cam 33, thereby driving the four groups of supporting springs 56 and the hexagonal forging die 53 to move downward synchronously. Figure 13 and Figure 17 At this time, the multiple groups of positioning clamping shafts 54 at the bottom of the hexagonal forging die 53 can first be inserted into the positioning guide grooves 435 inside the forging bottom die 434, and then the elevator bolt blank 1 can be limited from multiple angles to prevent the elevator bolt blank 1 from shifting during subsequent forging. Subsequently, the four groups of hexagonal forging dies 53 can be directly aligned to the top of the elevator bolt blank 1 inside the forging bottom die 434, thereby completing the forging shaping operation. After the forging is completed, the large radius outer aid of the forging cam 33 is separated from the forging card seat 52, and the small radius outer aid is fitted with the forging card seat 52. At the same time, the four groups of support springs 56 can drive the forging card seat 52 to lift and reset through elastic force. At this time, Figure 8 , the above-mentioned notched chuck 414 and the limiting rotating groove 413 are just limited, and then the notched chuck 414 drives the cam rotating disk 47 to rotate intermittently through the limiting lever 45, and then drives the transmission rotating seat 436 to intermittently load the next group of elevator bolt blanks 1, such as Figure 10 ,、 Figure 11 and Figure 14, when ejecting and blanking the forged elevator bolt blank 1, the driving turntable 436 with the forged elevator bolt blank 1 can rotate intermittently along the inside of the arc-shaped slide plate 422. The arc-shaped slide plate 422 can limit and protect the elevator bolt blank 1 limited inside the driving turntable 436 to prevent the elevator bolt blank 1 from being thrown out due to gravity and rotational inertia subsequently. When the driving turntable 436 rotates to the bottommost working position, such as Figure 10 , at this time, the fixed guide rod 4324 can displace towards the bottom under the guidance of the guiding deflector 423. As the driving turntable 436 rotates, the fixed guide rod 4324 can drive the ejecting guide shaft 4322 to move downward synchronously through the guiding slide block 4323. The ejecting guide shaft 4322 can then press against the bottom of the elevator bolt blank 1 elastically clamped by two sets of 4236, causing the elevator bolt blank 1 to gradually separate from the two sets of spring clamps 4326. When the driving turntable 436 rotates to the bottommost position, at this time, the ejecting guide shaft 4322 completely ejects the elevator bolt blank 1 inside the forging bottom die 434. At the same time, the fixed guide rod 4324 is completely separated from the guiding deflector 423, and the two sets of return springs 4325 can elastically contract to drive the fixed guide rod 4324 and the ejecting guide shaft 4322 to return to their original positions, such as Figure 2 , Figure 10 and Figure 16 , the ejected elevator bolt blank 1 falls to the upper part of the blanking slide block 13. When blanking multiple groups of ejected elevator bolt blanks 1, such as Figure 7 shown, when the above-mentioned cam turntable 47 rotates, it can synchronously drive the second synchronous pulley 48 inside to rotate. The second synchronous pulley 48 can then drive the third synchronous pulley 49 and the driving guide roller 411 to rotate synchronously through the second synchronous belt 410. The driving guide roller 411 can drive the cam chute 41 to rotate. At this time, the driving guide roller 411 can drive the fixed bushing 442 and the blanking guide plate 443 to perform intermittent cyclic displacement on the upper part of the blanking slide block 13 through the sliding limit between the cam chute 41 and the support slide shaft 441, so that the blanking guide plate 443 can export the elevator bolt blank 1 through the two side openings of the blanking slide block 13, facilitating subsequent reprocessing of the elevator bolt blank 1.
