[0002] A mechanical locking ring is a fastener with a special design and function, commonly used in mechanical assembly. It mainly achieves locking and fixing functions through the characteristics of its internal structure and materials. It is widely used in various fields such as automobiles, ships, aerospace, and mechanical manufacturing. The locking ring forming machine is a mechanical equipment specially used for integrally forming this type of locking ring.

[0003] The prior art publication number CN213701420U provides a stamping and forming device for producing staggered tooth locking rings, which relates to a mechanical device, specifically including a base, a support plate, and an external punch. The four corners of the upper surface of the base are respectively fixedly connected to the bottom end of a vertically installed support rod, the top end of the support rod is fixedly connected to the bottom surface of the support plate, and a horizontal lifting plate is slidably installed between the support rods. The two ends of the bottom surface of the lifting plate are respectively fixedly connected to the top end of a vertical hydraulic rod, the bottom end of the hydraulic rod is fixedly connected to the upper surface of the base, and the external punch is welded and fixed to the middle part of the upper surface of the lifting plate. During the implementation of the utility model, the annular structure of the locking ring is formed by a single stamping process, which reduces the molding process of the locking ring, saves the production cost of the locking ring, and improves the practicality of the molding device.

[0004] In the above patent, the locking ring is directly formed by a one-time stamping process using a hydraulic rod. However, this stamping process can only stamp the smooth surface of the locking ring, so the operator has to manually operate to make the double threads of the locking ring. As a result, the forming process of the double-threaded locking ring is too cumbersome and complicated, which greatly reduces the practicality of the lock ring forming machine. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a double-thread lock ring forming machine to solve the technical problems such as the double-thread lock ring forming process being too complicated.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Example

[0025] The following is combined with Figure 1 -Attached Figure 7The application is further described in detail. A double thread locking ring forming machine comprises a forming assembly 1, a machine body assembly 2, and a controller 3. The machine body assembly 2 is fixedly installed at one end of the forming assembly 1 away from the ground, and the controller 3 is located at the right side of the machine body assembly 2 and electrically connected thereto. A lower mold is fixedly installed at the center of the support plate of the forming assembly 1, and a feeding groove 13 is formed in the lower mold. The machine body assembly 2 comprises a pouring assembly 21, a fixed plate 22, a stamping assembly 23, and a mold assembly 24. The pouring assembly 21 is fixedly installed at one end of the fixed plate 22 away from the ground. The stamping assembly 23 is fixedly installed at one end of the fixed plate 22 away from the pouring assembly 21. The mold assembly 24 is located at the telescopic end of the stamping assembly 23. The mold assembly 24 comprises a top mold 241. An outer thread ring 243 is formed in the inner ring of the top mold 241. An inner thread column 242 is fixedly installed at the center of the top mold 241. The top mold 241 is rotatably installed on the stamping assembly 23. The mold assembly 24 further comprises a fixed block 248 and a passive gear 246. The fixed block 248 is L-shaped. The long side of the fixed block 248 is fixedly installed on the stamping assembly 23. The short side of the fixed block 248 is fixedly installed with a motor 247 near one side of the stamping assembly 23. The output end of the motor 247 is connected with a driving gear 245. The driving gear 245 is used to drive the passive gear 246 to rotate. The stamping assembly 23 comprises a moving plate 232 and a moving rod 233. The moving plate 232 is movably penetrated and installed on the moving rod 233. An electric push rod 231 is fixedly installed on one side of the moving plate 232 away from the top mold 241. A plurality of protruding shafts are fixedly installed on the outer edge of the top mold 241. A plurality of recessed grooves are formed at the edge of the lower mold. The protruding shafts and the recessed grooves are matched and inserted to seal and fix the upper and lower molds. A cylindrical protruding part is integrally protruded on one side of the lower mold near the controller 3. A flow-through hole 16 is formed at the center of the protruding part. A plurality of clamping grooves 15 are formed on the outer ring of the protruding part. An injection head is installed at one end of the pouring assembly 21 closest to the ground. A through hole 214 is formed at the center of the injection head. A plurality of clamping parts 215 are movably installed on the outer side of the injection head. The clamping parts 215 are inserted into the clamping grooves 15. The through hole 214 and the flow-through hole 16 are in flow communication. The pouring assembly 21 further comprises a material barrel 211. An on-off device 212 for controlling the flow of materials is fixedly installed on one side of the material barrel 211 near the through hole 214. A hollow hose 213 is fixedly installed on one side of the on-off device 212 away from the material barrel 211. The hose 213 is fixedly connected with the injection head. The hose 213 is made of stainless steel.

[0026] The tail end of the electric push rod 231 is fixedly installed on the fixed plate 22. Thus, when the electric push rod 231 is stretched and contracted, the entire mold assembly 24 can be directly moved, and the material stamping effect is achieved.

[0027] Among them, the entire top mold 241 can rotate around its outer ring and on the movable plate 232, so that after the double-threaded lock ring in the mold is die-cast, it can be quickly demolded with the help of the electric push rod 231, thereby improving the demolding efficiency in the double-threaded lock ring molding machine.

[0028] Among them, the protrusions on the outer ring of the top mold 241 and the stabilizing groove 14 are of the same size, so that when the upper and lower molds are combined together, a sealing effect can be achieved by the mutual embedding of the protrusions and the stabilizing groove 14.

[0029] The hose 213 can be bent and stored, so that the normal operation of the hose 213 will not be affected when the stamping assembly 23 and the entire mold assembly 24 are extended or retracted.

[0030] The engaging members 215 can be plugged in and out, so that when the through hole 214 is inserted into the outer ring of the flow hole 16, the purpose of sealing the hose 213 for transmission can be achieved by first pulling out several engaging members 215 and inserting them into the engaging groove 15.

[0031] The working principle of the present invention is described below: Unless otherwise specified, the various mechanical structures inside the double-threaded lock ring forming machine are all fixed by threads. In order to observe the professional and technical features more intuitively, the bolt connections are appropriately hidden in the figure. When the double-threaded lock ring forming machine is in use, the operator can intelligently control all the electronic devices in the forming component 1 and the body component 2 through the controller 3. When the double-threaded lock ring forming machine is performing lock ring forming, the operator places all the molten materials for lock ring forming into the pouring component 21, and then the operator starts the shutter 212 to control the inflow and outflow of the internal molten liquid. The operator starts the electric push rod 231 and allows the electric push rod 231 to move downward with the moving plate 232 on the moving rod 233. When the protrusion on the outer ring of the top mold 241 is inserted into the stabilizing groove 14, the extension of the electric push rod 231 is stopped. At this time, since the engaging member 215 is in the engaging groove 15 and the through hole 214 is aligned with the flow hole 16, the shutter 212 The molten material is controlled to be poured into the mold through the hose 213. At this time, the electric push rod 231 in the stamping assembly 23 runs again and stamps the material in the mold. Due to the presence of the internal thread column 242 and the external thread ring 243, a double-threaded lock ring can be directly formed in the mold. When the double-bolt lock ring is cooled, the motor 247 rotates the active gear 245, causing the passive gear 246 to rotate accordingly, and causing the top mold 241 to rotate continuously in the movable plate 232. Combined with the upward movement of the electric push rod 231 with the top mold 241, the threads in the double-threaded lock ring can be slowly rotated along the internal thread column 242 and the external thread ring 243, so that the internal mold of the double-threaded lock ring forming machine can be quickly demoulded, so that the double-threaded lock ring forming machine can perform integrated molding of the double-threaded lock ring and perform rapid demoulding when in use, greatly improving the practicality of the double-threaded lock ring forming machine and the efficiency of making double-threaded lock rings.

[0032] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
