DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 3 , Fig.11 In an embodiment of the present invention, a multifunctional integrated forging device is provided for forging a tool holder 6, comprising a base frame 1, a conveying mechanism 2 is installed on the base frame 1, a vertical frame 3 is provided on the base frame 1, a lower die placed on the conveying mechanism 2 can pass through the bottom of the vertical frame 3, an upper die 4 is installed on the top of the vertical frame 3, a clamping mechanism 5 is symmetrically installed on both sides of the vertical frame 3, the clamping mechanism 5 comprises two symmetrically arranged pads 51, one side of the two pads 51 is fixedly connected by a bottom plate 54, a plurality of pulleys are rotatably connected between the two pads 51, a first belt 56 is provided on the outer periphery of the pulley, a second hydraulic telescopic rod 33 is installed on the outer side of the vertical frame 3, and an output end of the second hydraulic telescopic rod 33 is fixedly installed on the bottom plate 54.

[0029] Because of the high hardness of the material of the tool holder 6, a large tonnage is required during the forging production process. The original production process required a 3500T press. The original production process was: blanking-heating-die forging-machining-final inspection. The changed process is: blanking-heating-die forging-secondary reheating-die forging-machining-final inspection. After the process improvement, the production equipment was reduced from the original 3500T to 1600T, the production energy consumption was reduced, and the investment in production equipment was reduced.

[0030] In the present application, preferably, an infrared sensor is provided on the stand 3, and a first hydraulic telescopic rod 32 is installed on the upper end of the stand 3. The output end of the first hydraulic telescopic rod 32 is installed on the upper die 4. When the infrared sensor senses the die transported on the conveying mechanism 2, the second hydraulic telescopic rod 33 first drives the clamping mechanisms 5 on both sides to be relatively close. When the pads 51 on both sides drive the pulleys and the first belt 56 on the upper side to be relatively close, the die is clamped by the structures on both sides to be kept directly below the upper die 4 for forging processing. More importantly, after the first belts 56 on both sides contact the die, the die will not be rigidly limited. The die can still move a distance after contact. After being completely located below the upper die 4, the movement of the first belt 56 can be restricted, thereby maintaining the stability of the die, so as to facilitate forging with the upper die 4. In this way, the upper die 4 can be prevented from directly pressing down on the forging and the displacement between the die and the die, which helps to improve the yield rate. Moreover, it is not easy to cause the die surface to contact with the rigid clamping and cause damage.

[0031] As shown in the bottom frame 1, the vertical frame 3 is symmetrically embedded with side grooves 31 on both sides, and the two ends of the upper mold 4 are slidably connected in the side grooves 31. The vertical columns that slide through the upper mold 4 are symmetrically fixedly connected on both sides of the side grooves 31, so that the first hydraulic telescopic rod 32 is relatively stable when driving the upper mold 4 to move up and down. The clamping mechanism 5 is located at the lower side of the side groove 31, so that the clamping mechanism 5 clamping the mold will not interfere with the processing.

[0032] Preferably, Figure 1-Figure 4As shown, the chassis 1 is two symmetrically arranged plates, the chassis 1 is installed and fixed at the lower inner side of the conveying mechanism 2, the conveying mechanism 2 includes a conveying shaft 21 symmetrically rotatably connected between the two ends of the two groups of chassis 1, the conveying shaft 21 is preferably connected to a driving motor, and a conveying belt 22 is sleeved on the outer periphery of the two groups of conveying shafts 21. The conveying shaft 21 is driven to rotate to drive the conveying belt 22 to convey the mold. A plurality of support shafts 23 are provided on the lower side of the conveying belt 22 between the two groups of conveying shafts 21, and the support shaft 23 is rotatably connected between the two chassis 1. , a pad 24 is provided between the upper and lower sides of the conveyor belt 22, the pad 24 is fixedly connected between the two base frames 1, the pad 24 is arranged opposite to the upper mold 4, the pad 24 can be used for support, the pad 24 and the inner side of the conveyor belt 22 slide and fit, the support shaft 23 belongs to the driven wheel, the conveying shaft 21 belongs to the driving wheel, the conveying shaft 21 rotates and drives the conveyor belt 22 to convey the mold, the support shaft 23 can provide support, and when the mold is conveyed to the top of the pad 24, it is just facing the upper mold 4, at this time, the processing can be carried out, and the pad 24 can provide stable support. Among them, the upper and lower surfaces of the pad 24 are provided with multiple holes, and the multiple holes are internally connected, and the outer array of the opening of the hole is provided with multiple inclined surfaces. Such a setting can facilitate ventilation in the pad 24, so that the pad 24 can be blown from both the upper and lower sides, so that a gap can be formed between the inner side of the conveyor belt 22 and the surface of the pad 24, which can reduce friction during transportation, thereby reducing wear, and only provide support when the upper mold 4 contacts the mold for processing, which can increase the service life of the equipment. Furthermore, a gas nozzle 34 connected to the hole in the cushion block 24 is provided on one side of the stand 3, and gas can be continuously injected into the cushion block 24 through the gas nozzle 34. A gas receiving hole 11 for connecting the gas nozzle 34 and the hole in the cushion block 24 is provided on one side of the base frame.

[0033] like Figure 5-Figure 10As shown, the backing plate 51 has an isosceles trapezoid structure. The bottom plate 54 is fixedly connected to the lower bases (the longer bottom sides) of the two backing plates 51. The pulley includes a first conveying wheel 52, a second conveying wheel 53, and a transmission shaft 55. The first conveying wheels 52 are symmetrically and rotatably connected to both sides of the upper bases (the shorter bottom sides) of the two backing plates 51. Four second conveying wheels 53 are rotatably connected to one side of the lower bases of the two backing plates 51. Two transmission shafts 55 are also rotatably connected to one side of the upper base of the backing plate 51 and are located between the two first conveying wheels 52. The first belt 56 is wound around the outer peripheries of the first conveying wheel 52 and the second conveying wheel 53. The transmission shaft 55 jacks up the lower side of the first belt 56 and approaches the upper side of the first belt 56. That is, the first conveying wheel 52 and the second conveying wheel 53 cooperate with the transmission shaft 55 to tighten the first belt 56 to form an isosceles trapezoid structure, and the bottom of the first belt 56 forms a "Ji" shape by the second conveying wheel 53 and the transmission shaft 55. Preferably, the first belt 56 is located outside the backing plate 51. In this way, during contact, if the mold contacts the hypotenuse position of the first belt 56, it can play a guiding role while the conveyor belt 22 is conveying, and when the mold is clamped by the first belts 56 on both sides, before reaching below the upper mold 4, the first belt 56 can rotate by virtue of the rolling of the first conveying wheel 52, the second conveying wheel 53, and the transmission shaft 55, thus not affecting the conveyance of the mold.

[0034] Among them, the transmission shaft 55 includes a first rotating shaft 5501 rotatably connected between the two backing plates 51. First transmission rings 5502 are sleeved and fixedly arranged around both ends of the first rotating shaft 5501. First tooth patterns 5503 are provided on the outer periphery of the first rotating shaft 5501. A second belt 58 that is in transmission cooperation with the first tooth patterns 5503 is arranged for transmission connection between the two first rotating shafts 5501. A limiting shaft 57 for restricting the conveyance of the first belt 56 is arranged between the two first rotating shafts 5501. The limiting shaft 57 is in transmission cooperation with the second belt 58. In this way, when the first belt 56 contacts the mold, since the conveyor belt 22 drives the mold to move, the mold can drive the first belt 56 to convey through friction. At this time, because the first belt 56 can drive the transmission shaft 55 to rotate, the limiting shaft 57 can be driven to rotate synchronously by the synchronous rotation of the transmission shaft 55 and the second belt 58. As it rotates, the limiting shaft 57 gradually limits the first belt 56. At this time, the friction provided by the first belt 56 can relatively stably restrict the mold, which is convenient for cooperating with the positioning of the mold to facilitate the contact processing between the upper mold 4 and the mold.

[0035] Among them, the limiting shaft 57 includes a second rotating shaft 5701 rotatably connected between the two pads 51, and the second rotating shaft 5701 has a second transmission ring 5702 fixedly arranged on the outer periphery at both ends, and the second transmission ring 5702 is matched with the first belt 56 for transmission, and the second rotating shaft 5701 is provided with a second tooth pattern 5703 for transmission matching with the second belt 58 on the outer periphery, and the second rotating shaft 5701 is provided with a clamping plate 5704 fixedly arranged on the outer periphery, and the clamping plate 5704 is located on the upper side of the second belt 58, and the end of the clamping plate 5704 matches the second belt 58 and the inner side of the conveyor belt 22. Preferably, the inner sides of the conveyor belt 22 and the second belt 58 are both provided with equidistant strips. shaped groove, and the end of the card plate 5704 is in the shape of an inclined surface, so that when the second transmission ring 5702 and the first transmission ring 5502 rotate in coordination with the first belt 56, the second belt 58 can also rotate synchronously, and drive the card plate 5704 to rotate and contact the strip-shaped groove on the back of the first belt 56, thereby limiting the first belt 56 from continuing to rotate. In order to facilitate the retraction of the card plate 5704, a torsion spring is connected between the second rotating shaft 5701 and the pad 51. The torsion spring acts on the end of the card plate 5704 to move away from the first belt 56. In this way, as the second hydraulic telescopic rod 33 drives the clamping mechanism 5 relatively away, the first belt 56 no longer contacts the mold, and then the card plate 5704 can rotate in the opposite direction, thereby no longer limiting the first belt 56.
