Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, and particularly relates to a bolt stamping die. Background Technique

[0002] A bolt stamping machine is generally used for stamping and forming bolts on workpieces to be processed. The stamping machine relies on the power of conventional or special stamping equipment to directly apply a deforming force to the sheet metal in the die and cause deformation, thereby obtaining mechanical equipment for product parts with a certain shape, size, and performance. When using a bolt stamping machine, it is necessary to place the bolt blank into the die, and then use a punch to stamp out the hexagon. After stamping, the bolt needs to be taken out of the die. However, the stamped bolt is easily stuck in the die, making it inconvenient to take out, thus affecting the stamping efficiency. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a bolt stamping die, which can eject the stamped die to improve the stamping efficiency.

[0004] Therefore, the technical solution of the utility model is: a bolt stamping die, including a base, a turntable, a stamping module, and a jacking assembly. The turntable is rotatably installed on the base, and at least two stamping modules are provided on the turntable. A stamping groove is provided in the stamping module, and a circular step surface is provided at the bottom of the stamping groove. A flared mouth is connected below the circular step surface; the jacking assembly includes a jacking rod, the top end of the jacking rod can extend into the stamping groove, and an inclined surface is provided at the top end of the jacking rod, which can be fitted with the inner wall of the flared mouth and is pressed down by the inner wall of the flared mouth.

[0005] Based on the above solution and as a preferred solution of the above solution: when the turntable drives the stamping module to rotate, the inner wall of the flared mouth on the stamping module presses down the inclined surface at the top end of the jacking rod until the jacking rod disengages from the flared mouth.

[0006] Based on the above solution and as a preferred solution of the above solution: the jacking assembly further includes a jacking cylinder and a spring. The lower part of the jacking rod is placed in the jacking cylinder, and a spring is provided below the jacking rod, and the spring is in a compressed state.

[0007] Based on the above solution and as a preferred solution of the above solution: a stamping station and a blanking station are provided on the turntable, and the jacking assembly is located at the blanking station.

[0008] Based on the above solution and as a preferred solution of the above solution: the turntable is installed on the output shaft of a rotating motor, the rotating motor is fixed on the base, and the rotating motor drives the turntable to rotate, driving the stamping module to switch positions between the stamping station and the blanking station.

[0009] When in use, the bolt blank is placed in the stamping groove of the stamping module. Under the action of the turntable, the bolt blank is sent under the stamping head. The stamping head presses the bolt blank downward to form it. Under the restriction of the stamping groove, the bolt blank is formed into a bolt; the stamped bolt is brought to the unloading station by the turntable. After arriving at the unloading station, the jacking rod is opposite to the bell mouth of the stamping groove. Therefore, the jacking rod is lifted upward under the action of the spring, thereby ejecting the stamped bolt from the stamping groove, which is convenient for material removal. After the material removal is completed, a new bolt blank can be directly placed, or another loading station can be set up; at this time, the top of the jacking rod is still in the stamping groove. Since the inner wall of the bell mouth is an inclined structure, when the stamping module moves, the inner wall of the bell mouth will press down the jacking rod until the jacking rod completely leaves the bell mouth, which is convenient for the stamping module to enter the next station.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: multiple stamping modules are arranged on the turntable, which can alternately enter the stamping station to perform bolt stamping work, thereby improving the stamping efficiency; at the same time, a lifting rod is arranged at the unloading station, and the lifting rod can automatically lift the stamped bolts under the action of the spring, thereby reducing the difficulty of taking out the bolts, and the automatic resetting of the lifting rod is achieved through the trumpet mouth at the bottom of the stamping module. It is easy to use, does not require other operations, and saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Referring to the drawings. The bolt stamping die described in this embodiment includes a base 1, a turntable 2, a stamping module 3 and a jacking assembly 4. The turntable 2 is provided with a stamping station and a blanking station. The jacking assembly 4 is located at the blanking station. The turntable 2 is installed on the output shaft of a rotating motor 5, and the rotating motor 5 is fixed on the base 1. The rotating motor 5 drives the turntable 2 to rotate, driving the stamping module 3 to switch positions between the stamping station and the blanking station.

[0019] At least two stamping modules 3 are provided on the turntable 2. A stamping groove 31 is provided in the stamping module 3. A circular step surface 32 is provided at the bottom of the stamping groove 31, and a flared mouth 33 is connected below the circular step surface 32. The jacking assembly 4 includes a jacking rod 41, a jacking cylinder 42 and a spring 43. The lower part of the jacking rod 41 is placed in the jacking cylinder 42, and a spring 43 is provided below the jacking rod 41, and the spring 43 is in a compressed state. The top end of the jacking rod 41 can extend into the stamping groove 31. An inclined surface 44 is provided at the top end of the jacking rod 41, which can be attached to the inner wall of the flared mouth 33 and is pressed down by the inner wall of the flared mouth 33. When the turntable 2 drives the stamping module 3 to rotate, the inner wall of the flared mouth 33 on the stamping module 3 presses down the inclined surface 44 at the top end of the jacking rod 41 until the jacking rod 41 disengages from the flared mouth 33.

[0020] During use, place the bolt blank 6 into the stamping groove 31 of the stamping module 3. Under the action of the turntable 2, the bolt blank 6 is fed under the stamping head, and the stamping head presses down the bolt blank 6 to form it. Restricted by the stamping groove 31, the bolt blank 6 forms a bolt 7. The stamped bolt 7 is carried by the turntable to the blanking station. After reaching the blanking station, the jacking rod 41 is opposite to the flared opening 33 of the stamping groove. Therefore, under the action of the spring 43, the jacking rod 41 jacks up upward, thereby ejecting the stamped bolt 7 from the stamping groove 31, facilitating material taking. After the material taking is completed, a new bolt blank can be directly placed, or a feeding station can be set up. At this time, the top end of the jacking rod 41 is still located in the stamping groove 31. Since the inner wall of the flared opening 33 is an inclined structure, when the stamping module 3 moves, the inner wall of the flared opening 33 will press down the jacking rod 41 until the jacking rod 41 completely leaves the flared opening 33, facilitating the stamping module to enter the next station.
