Description

Technical Field

[0001] The utility model relates to the technical field of nut processing, and in particular to a raw material cold heading machine for processing flange nuts. Background Art

[0002] Cold heading machine is a special equipment mainly used for mass production of nuts, bolts and other fasteners. It is a forging and forming equipment that thickens the top of bars or wires at room temperature. It is a special equipment mainly used for mass production of nuts, bolts and other fasteners. Cold heading machine uses cold heading method to upset the heads of bolts and screws, which can minimize cutting work and directly form them into the required shape and size, which can not only save a lot of materials, but also greatly improve production efficiency and significantly improve the mechanical strength of upset parts.

[0003] The processing steps generally include feeding, cutting, forming and discharging. First, the strip raw material is fed into the equipment, then the strip raw material is cut into segments, the segmented strip raw material is extruded and formed under the action of the mold, and finally the material is discharged to the designated position. In the forming process, the semi-finished product is transferred between each cold heading mold in sequence through a clamp for processing in sequence. The chamfering mold is the last cold heading mold, that is, the last processing step. Its mold closing time is different from other molds. The mold closing drive assembly needs to have different driving time for the chamfering mold. Therefore, the traditional mold closing device includes a frame, a main motor, a drive shaft and a rocker shaft. The rocker shaft and the driving shaft are respectively coordinated with the frame for rotation, the rocker shaft is provided with a passive rocker corresponding to each cold heading mold, the driving shaft is provided with a driving block corresponding to each passive rocker, one end of the passive rocker is linked to the cold heading mold, and the other end is against the driving block, the driving block is provided with an undulating ramp against the passive rocker arm, when the main motor drives the driving shaft to rotate, different positions of the ramp are against the passive rocker arm, and the passive rocker arm can be pushed to swing according to the different spacings of the ramp relative to the central axis of the driving shaft, because the undulating shape of the driving block corresponding to the chamfering mold is different from other driving blocks, the chamfering mold can have different clamping times.

[0004] However, in the process of extrusion molding, the traditional clamping method is usually used to pick up and move the nut, and nuts of different specifications are subjected to different forces when picking up. If the program does not adjust the stroke of the clamping clamp properly, the nut will be clamped with too much force, or the clamping force will be insufficient, causing it to fall. In view of this, a raw material cold heading machine for processing flange nuts was developed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1~Figure 4 As shown, this embodiment provides a raw material cold heading machine for processing flange nuts, including

[0028] A support rod 1, wherein a bottom plate 2 is arranged on the support rod 1;

[0029] A material storage component 3, wherein the material storage component 3 is arranged on the support rod 1;

[0030] A feeding assembly 4, wherein the feeding assembly 4 is arranged on the inner side of the support rod 1;

[0031] The material storage assembly 3 includes a force frame 3-1, which is arranged on the support rod 1, and an operation port 3-2 is arranged on the force frame 3-1. A No. 1 cylinder 3-3 is mounted on the base plate 2, and a force groove 3-4 is arranged on the No. 1 cylinder 3-3. A shaping base frame 3-5 is arranged in the force groove 3-4. A mounting frame 3-6 is arranged on the support rod 1, and a mounting plate 3-7 is arranged on the mounting frame 3-6. A motor 3-8 is arranged on the mounting plate 3-7, and a lead screw 3-9 is arranged at the output end of the motor 3-8.

[0032] In this embodiment, the No. 1 cylinder 3-3 can drive the force frame 3-1 to move up and down against the inner wall of the support rod 1 for stamping and forming, and the molding base frame 3-5 can be arbitrarily replaced with a mold of the required stamping shape.

[0033] Specifically, bearings 3-10 are mounted on the opposite ends of the lead screw 3-9, a nut 3-11 is movably screwed on the lead screw 3-9, a slider 3-12 is arranged at the lower end of the nut 3-11, a slide groove 3-13 is arranged on the mounting frame 3-6, and a connecting plate 3-14 is arranged on the nut 3-11.

[0034] In this embodiment, after the motor 3-8 drives the screw 3-9 to rotate, the screw 3-9 rotates in the bearing 3-10 and drives the nut 3-11. The nut 3-11 is limited by the slider 3-12, and the slider 3-12 is embedded in the slide groove 3-13, causing the nut 3-11 to be unable to rotate and can only translate following the screw 3-9, thereby driving the translation of the connecting plate 3-14.

[0035] Furthermore, the feeding assembly 4 includes a No. 2 cylinder 4-1, and the No. 2 cylinder 4-1 is arranged on the connecting plate 3-14, and a placing plate 4-2 is arranged on the output end of the No. 2 cylinder 4-1, and a feeding rod 4-3 is arranged on the placing plate 4-2, and a nut suction cup 4-4 is arranged at the end of the feeding rod 4-3, and a vacuum pump 4-5 is arranged on the placing plate 4-2, and a vacuum tube 4-6 is connected to the vacuum pump 4-5.

[0036] In this embodiment, the nut suction cup 4-4 sucks the nut and moves it to the molding base frame 3-5, the No. 2 cylinder 4-1 drives the placement plate 4-2 to move downward, and the No. 1 cylinder 3-3 and the No. 2 cylinder 4-1 operate simultaneously to stamp the nut.

[0037] Furthermore, the force groove 3-4 is arranged on the No. 1 cylinder 3-3, the force groove 3-4 is arranged in the operating port 3-2, the bearing 3-10 is arranged on the mounting frame 3-6, a part of the slider 3-12 is arranged in the slide groove 3-13, one end of the vacuum tube 4-6 is connected to the nut suction cup 4-4, the support rod 1 is a door-type structure, and the motor 3-8 is arranged on the outside of the support rod 1.

[0038] When the nut needs to be formed, the right side of the support rod 1 is placed above the conveyor belt in advance. The conveyor belt conveys the semi-finished nut. When the nut is directly below the support rod 1, it moves downward through the No. 2 cylinder 4-1, driving the nut suction cup 4-4 to absorb the semi-finished nut. After the motor 3-8 drives the screw 3-9 to rotate, the screw 3-9 rotates in the bearing 3-10 and drives the nut 3-11. The nut 3-11 is limited by the slider 3-12, and the slider 3-12 is embedded in the slide groove 3-13, resulting in the nut 3-11 being unable to rotate and can only follow the screw 3-9 for translation, thereby driving the translation of the connecting plate 3-14. The nut suction cup 4-4 absorbs the nut and moves it to the top of the shaping base frame 3-5, and the No. 2 cylinder 4-1 drives the placement plate 4-2 to move downward. The No. 1 cylinder 3-3 and the No. 2 cylinder 4-1 operate simultaneously to stamp the nut.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
