Description

Technical Field

[0001] The invention relates to the technical field of nut splicing, in particular to a nut splicing device after hot forging. Background Art

[0002] The nut receiving device after hot forging is usually used in the hot forging production process to remove the formed nuts or other parts from the forging die and carry out the next step of processing.

[0003] The patent with patent announcement number CN208390938U relates to a nut receiving device after hot forging, including a mounting base, a receiving groove, a storage basin, a rotating motor, a first connecting rod, a second connecting rod, a telescopic cylinder, a cooling fan, and a mounting bracket. The nut blanks produced by the previous equipment are received through the receiving groove. By setting the receiving groove as a double-layer structure, once the inner groove body is damaged, the inner groove body can be directly replaced, saving costs. By setting a water cooling pipe between the inner groove body and the outer groove body, the groove body can be cooled and protected. The nut blanks received by the receiving groove are stored in the storage basin. A rotating motor is set at the lower end of the storage basin to drive the storage basin to rotate so that the nut blanks flowing out of the receiving groove will not accumulate in one place in the storage basin, which is conducive to cooling and heat dissipation. The cooling fan set at the upper end of the storage basin can cool the nut blanks in the basin. Rollers are set on the mounting base plate and can move freely.

[0004] In the above patent, a water cooling pipe is set between the inner groove body and the outer groove body to cool the groove body and protect the groove body. However, the cooling effect on the nut is limited. The temperature of the nut after cooling treatment may still be too high, thereby affecting subsequent operations. For this reason, a hot forging nut connection device with air cooling and water cooling effects is designed. Summary of the Invention

[0014] The present invention provides a device for connecting nuts after hot forging. It has the following beneficial effects:

[0015] (1) The hot forged nut receiving device is configured to throw the hot forged nut into the interior of the feed plate, at which time the air-cooled heat sink is started, and the air-cooled heat sink performs air-cooling and cooling treatment on the nut passing through the feed plate, and then the nut falls and contacts the surface of the buffer plate 1, and then the nut, in cooperation with the buffer plate 1 and the telescopic elastic rod 1, buffers and absorbs the kinetic energy of the fall, to avoid damage or deformation of the nut surface due to the impact of free fall, and then falls into the water tank, at which time the coolant in the water tank cools the nut for cooling treatment, further improving the cooling effect on the nut, and avoiding the risk of thermal stress concentration or deformation caused by the nut after high-temperature forging directly contacting the coolant, and at the same time, the dual cooling method significantly improves the cooling efficiency, ensuring that the nut is quickly cooled to a suitable processing temperature.

[0016] (2) The nut receiving device after hot forging drives the conveyor plate to rotate by rotating the conveyor belt, and the threads inside the water tank are transported through the conveyor plate to the direction close to the rotating shaft 2. At this time, stable transportation of the nuts is achieved, and the accumulation or retention of nuts is avoided, thereby improving the operating efficiency of the equipment. The rotation of the rotating shaft drives the paddle plate to rotate, and the rotation of the paddle plate stirs the water flow in the direction close to the feed plate, so that the water circulation is accelerated, and the nuts are fully contacted with the coolant, further improving the uniformity of cooling and avoiding local excessive temperature.

[0017] (3) The nut receiving device after hot forging contacts the buffer plate 2 through the nut. At this time, the nut is buffered by the action of the rotating rod and the buffer plate 2, again avoiding damage or deformation of the nut surface due to the impact of free fall. The nut will slide along the surface of the screening plate, and then the nuts that do not meet the standards will fall into the inside of the collection box with the cooperation of the screening plate and the screening block. At this time, the screening effect is achieved along with the nut, which helps to improve the quality and consistency of the overall product and reduce rework and scrap rate. The output end of the electric push rod moves to drive the screening plate to move. The movement of the screening plate adjusts the height that the nut can pass through, thereby adapting to the screening of nuts of different sizes, thereby improving the versatility and adaptability of the equipment.

[0018] (4) The nut receiving device after hot forging drives the sleeve plate to move upward by moving the screening plate upward. At this time, the sleeve plate moves upward to adapt to nuts of different heights, further improving the adaptability and versatility of the equipment. The rotation of the contact wheel drives the cleaning roller to rotate, and the rotation of the cleaning roller drives the brush to rotate. At this time, the rotation of the brush cleans the surface of the nut, avoiding the subsequent screening of the nut due to impurities attached to the surface of the nut and thus affecting the accuracy of the screening. The rotation of the cleaning disk drives the brush to rotate, and the rotation of the brush cleans the top of the nut, further avoiding the subsequent screening work being affected by impurities attached to the top of the nut, ensuring that the impurities are completely removed.

[0019] (5) The nut receiving device after hot forging rotates by contacting and driving the other cleaning disk close to the transmission belt. At this time, the rotation of the two cleaning disks further improves the cleaning effect and efficiency of the top of the nut. The rotation of the half gear drives the tooth plate to move. The tooth plate moves to contact and collide with the surface of the nut. At this time, the nut vibrates under the action of the tooth plate, and the vibration cleaning effect of the attachments on the surface of the nut is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 7 One embodiment of the present invention is: a device for receiving nuts after hot forging, comprising a base 1, a water tank 2 is fixedly installed on the top of the base 1, a feed plate 3 is fixedly penetrated on the surface of the water tank 2, an air-cooled heat sink 4 is fixedly installed on the top of the feed plate 3, and a cooling device for cooling the nuts after hot forging is provided on the inner wall of the water tank 2. The cooling device comprises a fixed plate 51, the fixed plate 51 is fixedly installed on the inner wall of the water tank 2, a buffer plate 52 is slidably installed on the inner wall of the water tank 2, a telescopic elastic rod 53 is fixedly installed on the surface of the fixed plate 51, a rotating shaft 54 is rotatably installed on the inner wall of the water tank 2, a rotating shaft 2 55 is rotatably installed on the inner wall of the water tank 2, a conveyor belt 56 is transmitted between the rotating shaft 54 and the rotating shaft 2 55, and the rotation of the rotating shaft 54 drives the conveyor belt 56 to rotate. A paddle plate 57 is fixedly installed on the circumferential surface of the rotating shaft 54, and a receiving plate 58 is fixedly installed on the surface of the water tank 2.

[0030] The free end of the telescopic elastic rod 1 53 is fixedly connected to the buffer plate 1 52 , and one end of the rotating shaft 1 54 is connected to the output end of the motor. The rotating shaft 1 54 rotates under the action of the output end of the motor.

[0031] The surface of the conveyor belt 56 is provided with a conveying plate for facilitating the conveying of nuts. The angle of the feed plate 3 is set to an inclined angle. The rotation of the conveyor belt 56 drives the second rotating shaft 55 to rotate. At this time, the rotation of the conveyor belt 56 drives the conveying plate to rotate and conveys the threads inside the water tank 2 through the conveying plate toward the direction close to the second rotating shaft 55.

[0032] When this embodiment is working: after hot forging, the nut is thrown into the inside of the feed plate 3, and the air-cooling heat sink 4 is started at this time. The air-cooling heat sink 4 performs air cooling and cooling treatment on the nut passing through the feed plate 3, and then the nut falls and contacts the surface of the buffer plate 52. Then, the nut absorbs the kinetic energy of the fall with the cooperation of the buffer plate 52 and the telescopic elastic rod 53, so as to avoid damage or deformation of the nut surface due to the impact of free fall, and then falls into the water tank 2. At this time, the coolant inside the water tank 2 cools the nut for this cooling treatment, further improving the cooling effect of the nut, avoiding the nut after high-temperature forging directly contacting the coolant, and then causing the risk of thermal stress concentration or deformation. At the same time, the dual cooling method significantly improves the cooling efficiency, ensuring that the nut quickly drops to a suitable processing temperature.

[0033] When the nut falls into the water tank 2 for cooling, the shaft 1 54 rotates under the action of the motor output end. At this time, the rotation of the shaft 1 54 drives the conveyor belt 56 to rotate, and the rotation of the conveyor belt 56 drives the shaft 2 55 to rotate. At this time, the rotation of the conveyor belt 56 drives the conveyor plate to rotate and transports the threads inside the water tank 2 through the conveyor plate toward the direction close to the shaft 2 55. At this time, stable transportation of the nuts is achieved, avoiding the accumulation or retention of nuts, thereby improving the operating efficiency of the equipment. At the same time, the rotation of the shaft 1 54 drives the paddle plate 57 to rotate, and the rotation of the paddle plate 57 stirs the water flow toward the direction close to the feed plate 3, accelerates the water circulation, promotes full contact between the nut and the coolant, further improves the uniformity of cooling, and avoids local excessive temperature. The nut is then transported to the top of the shaft 2 55 under the action of the conveyor belt 56. At this time, the nut falls into the interior of the receiving plate 58 and is then processed in the next step.

[0034] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a discharge device for discharging and screening nuts is provided on the top of the base 1, and the discharge device includes a circular plate 61, a rotating disk 62 is rotatably installed on the top of the circular plate 61, a bevel plate 63 is fixedly installed on the inner wall of the circular plate 61, a screening plate 64 is fixedly installed on the top of the circular plate 61, a screening block 65 is fixedly installed on the top of the circular plate 61, a collecting box 66 is fixedly installed on the surface of the circular plate 61, an electric push rod 67 is fixedly installed on the surface of the circular plate 61, a rotating rod 68 is rotatably installed on the inner wall of the receiving plate 58, and a buffer plate 2 69 is fixedly installed on the circumferential surface of the rotating rod 68. The nut contacts the buffer plate 2 69. At this time, the nut is buffered by the action of the rotating rod 68 and the buffer plate 2 69, and a tension spring 610 is provided between the buffer plate 2 69 and the receiving plate 58.

[0035] The bottom of the rotating disk 62 is connected to the output end of the motor. The surface of the rotating disk 62 is provided with an arc surface 1 for arranging the nuts. The inner wall of the collecting box 66 is provided with an inclined surface 1. The output end of the electric push rod 67 is fixedly connected to the screening plate 64. The inner wall of the bevel plate 63 is provided with a conveying mechanism, and the bevel plate 63 conveys the nuts through the conveying mechanism.

[0036] The surface of the beveled plate 63 is set as arc surface 2, the surface of the screening plate 64 is set with arc surface 3 for screening nuts, the surface of the screening block 65 is set with arc surface 4 for guiding nuts, and a conveying mechanism is set inside the circular plate 61. Nuts that do not meet the standards fall into the inside of the collection box 66 with the cooperation of the screening plate 64 and the screening block 65.

[0037] A cleaning device for cleaning the nut is provided at the top of the circular plate 61, and the cleaning device includes a telescopic rotating rod 71, which is rotatably mounted on the top of the circular plate 61, and a contact wheel 72 is fixedly mounted on the circumferential surface of the telescopic rotating rod 71, and a cleaning roller 73 is fixedly mounted on the circumferential surface of the telescopic rotating rod 71, and a sleeve plate 74 is rotatably mounted on the free end of the telescopic rotating rod 71, and a cleaning disk 75 is rotatably passed through the surface of the sleeve plate 74, and a half gear 76 is fixedly mounted on the circumferential surface of the telescopic rotating rod 71, and a tooth plate 77 is slidably mounted on the surface of the circular plate 61, and the tooth plate 77 moves to contact and collide with the surface of the nut. At this time, the nut vibrates under the action of the tooth plate 77, and a telescopic elastic rod 2 78 is fixedly mounted on the surface of the circular plate 61.

[0038] The circumferential surface of the cleaning roller 73 is provided with bristles, and the bottom of the cleaning disk 75 is provided with bristles. A transmission belt 1 is connected between the telescopic rotating rod 71 and the cleaning disk 75. The free end of the telescopic elastic rod 2 78 is fixedly connected to the tooth plate 77, and the half gear 76 is engaged with the tooth plate 77. There are two cleaning disks 75, and the two cleaning disks 75 are in contact with each other. The screening plate 64 is fixedly connected to the sleeve plate 74, and the screening plate 64 moves upward to drive the sleeve plate 74 to move upward. At this time, the sleeve plate 74 moves upward to adapt to nuts of different heights, further improving the adaptability and versatility of the equipment.

[0039] When this embodiment is working: when the nut is conveyed to the top under the action of the rotating shaft 2 55, the nut then falls into the inside of the receiving plate 58, and then the nut contacts the buffer plate 2 69. At this time, the nut is buffered by the rotating rod 68 and the buffer plate 2 69, again avoiding damage or deformation of the nut surface due to the impact of free fall, and then the rotating disk 62 rotates under the action of the motor output end. The rotating disk 62 rotates and throws the nut inside it to the surroundings through centrifugal force, and then the nut is thrown to the surface of the bevel plate 63 under the action of the rotating disk 62. At this time, the bevel plate 63 conveys the nut through the conveying mechanism. At this time, the circular plate 61 relays the nut through the conveying mechanism, and then the nut reaches the screening under the action of the conveying mechanism. At plate 64, when the nuts that meet the standards pass through the bottom of the screening plate 64, the nuts will then fall into the qualified area. When the nuts do not meet the standards, the screening plate 64 will intercept them, and the nuts will slide along the surface of the screening plate 64. Then, the nuts that do not meet the standards fall into the interior of the collection box 66 with the cooperation of the screening plate 64 and the screening block 65. At this time, the screening effect of the nuts is achieved, which helps to improve the quality and consistency of the overall product, reduce rework and scrap rate, and when the electric push rod 67 is started, the output end of the electric push rod 67 moves to drive the screening plate 64 to move. The screening plate 64 moves to adjust the height at which the nuts can pass, thereby adapting to the screening of nuts of different sizes, thereby improving the versatility and adaptability of the equipment.

[0040] When this embodiment is working: when the screening plate 64 moves upward under the action of the electric push rod 67, the screening plate 64 moves upward and drives the sleeve plate 74 to move upward. At this time, the sleeve plate 74 moves upward to adapt to nuts of different heights, further improving the adaptability and versatility of the equipment. When the nut moves under the action of the conveying mechanism, the nut contacts the circumferential surface of the contact wheel 72. At the same time, the contact wheel 72 rotates under the action of the nut. The rotation of the contact wheel 72 drives the cleaning roller 73 to rotate. The rotation of the cleaning roller 73 drives the bristles to rotate. At this time, the rotation of the bristles cleans the surface of the nut, avoiding impurities adhering to the surface of the nut in the subsequent screening process of the nut, thereby affecting the accuracy of the screening. At the same time, the rotation of the telescopic rotating rod 71 drives the transmission belt to rotate, and the rotation of the transmission belt drives the cleaning The disc 75 rotates, and the rotation of the cleaning disc 75 drives the bristles to rotate. The rotation of the bristles cleans the top of the nut, further avoiding the influence of impurities attached to the top of the nut on the subsequent screening work, ensuring that the impurities are completely removed. Due to the contact between the two cleaning discs 75, the cleaning disc 75 close to the transmission belt rotates and contacts and drives the other cleaning disc 75 to rotate. At this time, the rotation of the two cleaning discs 75 further improves the cleaning effect and efficiency of the top of the nut. At this time, the telescopic rotating rod 71 rotates to drive the half gear 76 to rotate. Because the half gear 76 is engaged with the tooth plate 77, the rotation of the half gear 76 drives the tooth plate 77 to move. The tooth plate 77 moves to contact and collide with the surface of the nut. At this time, the nut vibrates under the action of the tooth plate 77, and the vibration cleaning effect of the attachments on the surface of the nut is achieved.
