Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, specifically a nut cold heading forming device. Background Technology

[0002] Cold heading is a novel chipless metal forming process. It utilizes the plastic deformation of metal under external force, and with the aid of a die, redistributes and transfers the metal volume to form the desired part or blank. Cold heading is best suited for producing standard fasteners such as bolts, screws, nuts, rivets, and pins.

[0003] When using existing nut cold heading forming equipment, after the nut is formed, the operator needs to remove the formed nut before placing the material to be processed at the processing position. This not only poses a certain degree of danger, but also has low processing efficiency, making it difficult to meet production needs. Utility Model Content

[0004] The purpose of this invention is to provide a nut cold heading forming device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the nut cold heading forming device includes a processing table, a support plate on the upper surface of the processing table, a mounting frame on the upper surface of the support plate, a hydraulic press on the mounting frame, an upper cold heading block at the output end of the hydraulic press, a groove on the upper surface of the support plate, a lower cold heading block inside the groove, a push rod slidably connected to the lower cold heading block, a fixing plate at the lower end of the push rod, the fixing plate being located below the support plate, a housing below the support plate, a spring inside the housing, the fixing plate being located above the spring, a notch on one side of the bottom of the mounting frame, a rotating shaft inside the notch of the mounting frame, a feeding disc on the rotating shaft, a motor inside the support plate, the output end of the motor passing through the support plate and fixedly connected to the rotating shaft, feeding grooves evenly distributed on the feeding disc, and a discharge hole on the support plate.

[0006] Preferably, the mounting frame is provided with a connecting frame on its side, and the connecting frame is provided with a guide cylinder on its side, with the lower end face of the guide cylinder located above the upper end face of the feeding tray.

[0007] Preferably, an observation slit is provided on the side of the feed cylinder.

[0008] Preferably, a guide groove is provided on the lower surface of the support plate and below the discharge hole, and the guide groove is inclined.

[0009] Preferably, the upper end of the top rod is provided with a limiting block, and the upper surface of the lower cold heading block is provided with a slot for accommodating the limiting block.

[0010] The beneficial effects of this utility model are:

[0011] When in use, this device can place new material into other feeding troughs during the cold heading process, thereby realizing the simultaneous cold heading and material placement to improve processing efficiency. At the same time, since the position of cold heading and the position of material placement are different, it can reduce the danger during production and has good results.

Detailed Implementation

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-3 As shown, a nut cold heading forming device includes a processing table 1, a support plate 2 on the upper surface of the processing table 1, a mounting frame 3 on the upper surface of the support plate 2, a hydraulic press 4 on the mounting frame 3, an upper cold heading block 5 at the output end of the hydraulic press 4, a groove on the upper surface of the support plate 2, a lower cold heading block 6 inside the groove, a push rod 7 slidably connected to the lower cold heading block 6, a fixing plate 8 at the lower end of the push rod 7, and the fixing plate 8 located below the support plate 2. Below plate 2 is housing 9, inside which is spring 10. Fixing plate 8 is located above spring 10. One side of the bottom of mounting bracket 3 is provided with a notch, inside which is rotating shaft 11. A feeding tray 12 is provided on rotating shaft 11. Inside support plate 2 is motor 13. The output end of motor 13 passes through support plate 2 and is fixedly connected to rotating shaft 11. Feeding tray 12 is provided with feeding grooves 14 evenly distributed. Support plate 2 is provided with discharge holes 15.

[0018] When processing nuts, the worker places the material for processing nuts into the feeding groove 14 on the feeding pan 12, and then starts the motor 13. The motor 13 drives the feeding pan 12 to rotate through the rotating shaft 11. As the feeding pan 12 rotates, it moves the material in the feeding groove 14. When the material in the feeding groove 14 enters the position directly above the lower cold heading block 6, the motor 13 stops. Then the hydraulic press 4 starts, and the hydraulic press 4 drives the upper cold heading block 5 to move downward. The upper cold heading block 5, by squeezing the material in the feeding groove 14 and cooperating with the lower cold heading block 6, can process the material into a nut blank. After the nut processing is completed, the hydraulic press 4 drives the upper cold heading block 5 to move upward. At the same time, under the action of the spring 10, it pushes the fixed plate 8 and the push rod 7. Moving upwards, the push rod 7 pushes the nut from the lower cold heading block 6 to the inside of the feeding groove 14. At this time, the upper end face of the push rod 7 is on the same plane as the upper end face of the support plate 2. Since the outer side of the formed nut has a curvature, when the motor 13 drives the feeding plate 12 to rotate through the rotating shaft 11, it can transfer the nut located on the push rod 7 from above the lower cold heading block 6. At the same time, it transfers the material to be processed back to above the lower cold heading block 6 so that the material can continue to be processed. When the processed nut enters the position of the discharge hole 15 with the rotation of the feeding plate 12, the nut in the feeding groove 14 will fall downwards under the action of gravity, so that the processed nut is removed from the feeding groove 14 so that the material can continue to be placed into the feeding groove 14.

[0019] When the feeding groove 14 on the feeding tray 12 is located between the upper cold heading block 5 and the lower cold heading block 6, one of the feeding grooves 14 on the feeding tray 12 will be aligned with the discharge hole 15. When processing the material, the nut in the feeding groove 14 can fall down through the discharge hole 15 during the processing time. If the nut gets stuck, it can be manually or with a screwdriver or other tools to push the nut out of the feeding groove 14. The feeding groove 14 should be inspected and impurities in the feeding groove 14 should be cleaned to ensure that the nut can fall down normally.

[0020] The operation of motor 13 and hydraulic press 4 is controlled by PLC, and the staff only need to be responsible for feeding materials.

[0021] Furthermore, a connecting frame 16 is provided on the side of the mounting frame 3, and a guide cylinder 17 is provided on the side of the connecting frame 16. The lower end face of the guide cylinder 17 is located above the upper end face of the feeding tray 12. The guide cylinder 17 is used to store the material to be processed. When there are no nuts or materials in the feeding trough 14, the material in the guide cylinder 17 can automatically fall into the feeding trough 14 under the action of gravity, thereby improving the accuracy and efficiency of material placement. In addition, the guide cylinder 17 can store multiple materials to ensure that materials can be stably placed into the feeding trough 14.

[0022] Furthermore, an observation slit is provided on the side of the guide cylinder 17 to facilitate observation and adjustment of the material inside the guide cylinder 17, and to avoid blockage.

[0023] Furthermore, a guide groove 18 is provided on the lower surface of the support plate 2 and below the discharge hole 15. The guide groove 18 is inclined so that the processed nuts will be discharged outward from the guide groove 18, making it convenient to collect the nuts.

[0024] Furthermore, a limiting block 19 is provided at the upper end of the push rod 7, and a slot for accommodating the limiting block 19 is provided on the upper surface of the lower cold heading block 6. When the upper cold heading block 5 presses the material downward, the push rod 7 has difficulty in effectively supporting the material, causing a bulge to appear at the center of the lower end face of the material, which affects the quality of the nut. By providing the limiting block 19, the push rod 7 can be prevented from moving downward continuously, keeping the lower end face of the cold-headed nut flat and ensuring the forming quality of the nut.
