Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a high-precision screw head molding die. Background Technology

[0002] The screw head is the top structure of a screw, used to transmit torque. It is used to tighten or loosen screws with tools such as screwdrivers and wrenches. Its design and shape directly affect installation efficiency, anti-slip properties, and applicable scenarios. Molding is an efficient method for mass production of screw heads.

[0003] Select carbon steel, stainless steel, etc. according to the performance requirements of the screw. The diameter must match the final product size. Remove the surface oxide layer by pickling or mechanical rust removal, and then apply lubricant to reduce friction in subsequent processing. The wire is cut into blanks by a feeder. The blanks are stamped in the mold to form head shapes such as cross grooves and hexagons.

[0004] The forming mold is fixedly installed on the machine frame during use. When the stamping groove of the screw head needs to be adjusted, the stamping mold head needs to be disassembled and reassembled. The process adjustment is cumbersome and time-consuming. To solve this problem, we propose a high-precision screw head forming mold. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a high-precision screw head forming mold.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision screw head forming mold, comprising a base plate, a first motor, a mounting ring, and a mounting tube. The first motor is mounted on the upper end of the base plate, and a turntable is mounted on the upper end of the first motor. A mounting frame is mounted on the upper end of the base plate, and a second hydraulic rod is mounted inside the mounting frame. A pressing head is mounted on the lower end of the second hydraulic rod. A ring seat is mounted on one end of the mounting frame, and a mounting ring is mounted inside the ring seat. Mounting tubes arranged in a circular array are embedded inside the mounting ring. A support ring is mounted inside the lower end of the mounting tubes. A guide rod is slidably mounted inside the support ring, and a punch is mounted on the lower end of the guide rod. A gear ring and a rotating ring rotatably mounted inside the ring seat are sleeved on the outer wall of the mounting ring. The second motor is mounted on one end of the mounting frame, and a gear that meshes with the gear ring is mounted on the output end of the second motor.

[0007] Preferably, the upper end of the support ring is provided with a spring sleeved on the outside of the guide rod, and the upper end of the spring is provided with a mating plate connected to the upper end of the guide rod. The spring structure elastically resets the punch after stamping.

[0008] Preferably, the punches at the lower end of the guide rod are of different specifications. Different specifications of punches are provided at the lower end of the guide rod, and various screw heads such as Phillips head and Torx head can be matched by rotating the mounting ring.

[0009] Preferably, a guide frame is provided at the upper end of the base plate, a guide groove is provided inside the upper end of the guide frame, a hydraulic rod is provided on one side of the guide frame, and a push plate is provided at the telescopic end of the hydraulic rod. The guide frame and the hydraulic rod cooperate to automatically push the billet to the turntable trough.

[0010] Preferably, the turntable has symmetrically distributed baffles fitted onto its outer wall, with an inlet and an outlet between the baffles, and a guide groove corresponding to the inlet. The baffles limit the movement and the guide groove positions the material, ensuring precise feeding and reducing the risk of manual intervention.

[0011] Preferably, a conveyor belt is provided at the upper end of the base plate, and the conveyor belt is located below the discharge port. The conveyor belt receives the finished product after stamping, realizing fully automated material unloading and avoiding manual material handling.

[0012] Preferably, the outer wall of the turntable is provided with material troughs arranged in a ring array, and the upper end of the bottom plate is provided with a support plate fixed to the lower end of the retaining ring. The ring array arrangement of the material troughs on the turntable, together with the retaining ring and the support plate, ensures stable transfer of the billet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a motor to drive a gear meshing with a gear ring on the outer wall of the mounting ring, causing the mounting ring to rotate within the ring seat. This allows the mounting tubes, arranged in a ring array, to switch to the stamping station. The mounting tubes contain punches of different specifications. The punches are connected to the guide rods by springs. When the hydraulic rod is pressed down, it squeezes the guide rods to complete the stamping. When the rod is reset, the spring rebounds and lifts the punches, avoiding manual contact with the stamping area, reducing operational risks, and eliminating the need to disassemble the mold. By rotating the punches, the mold change time is shortened. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, the present invention proposes a high-precision screw head forming mold, including a base plate 1, a motor 2, a mounting ring 9, and a mounting tube 11. The upper end of the base plate 1 is provided with the motor 2, the upper end of the motor 2 is provided with a turntable 12, the upper end of the base plate 1 is provided with a mounting frame 19, the mounting frame 19 is provided with a hydraulic rod 10, the lower end of the hydraulic rod 10 is provided with a pressing head 21, one end of the mounting frame 19 is provided with a ring seat 8, the ring seat 8 is provided with a mounting ring 9, the mounting ring 9 is embedded in the mounting tube 11 arranged in a ring array, the lower end of the mounting tube 11 is provided with a support ring 27, the support ring 27 is slidably installed with a guide rod 25, the lower end of the guide rod 25 is provided with a punch 28, the outer wall of the mounting ring 9 is sleeved with a gear ring 13 and a rotating ring 4 rotatably installed inside the ring seat 8, one end of the mounting frame 19 is provided with a motor 22, the output end of the motor 22 is provided with a gear 23 that meshes with the gear ring 13;

[0023] A spring 26 is provided at the upper end of the support ring 27 and sleeved on the outside of the guide rod 25. A docking plate 24 connected to the upper end of the guide rod 25 is provided at the upper end of the spring 26.

[0024] The specifications of the punch 28 at the lower end of the guide rod 25 are not uniform;

[0025] Based on the implementation steps of Example 1: When the blank enters below the corresponding punch 28, the hydraulic rod 20 drives the extrusion head 21 to descend. After the mating plate 24 is subjected to force, it presses the guide rod 25, thereby applying extrusion force to the spring 26. The spring 26 contracts under force, and the guide rod 25 moves the punch 28 to punch the blank into a specified shape. When the screw head of the same diameter needs to be replaced with a different mounting slot, the motor 22 drives the gear 23 to push the gear ring 13, which drives the mounting ring 9 to rotate inside the ring seat 8 through the rotating ring 4. This adjusts the position of different models of punches 28, quickly achieving the specified position of the corresponding model of punch 28. This avoids the cumbersome problem of disassembling and assembling fixed molds. After the screw head is stamped, the hydraulic rod 20 drives the extrusion head 21 to rise. The elastic force of the spring 26 lifts the mating plate 24 and drives the guide rod 25 and punch 28 to reset. Adjusting the mounting slot or mounting head specifications of the screw head is time-saving and convenient.

[0026] like Figures 1-5 As shown, compared with Embodiment 1, the high-precision screw head forming mold proposed in this utility model further includes: a guide frame 6 is provided on the upper end of the base plate 1, a guide groove 17 is provided inside the upper end of the guide frame 6, a hydraulic rod 5 is provided on one side of the guide frame 6, and a push plate 16 is provided at the telescopic end of the hydraulic rod 5.

[0027] The outer wall of the turntable 12 is fitted with symmetrically distributed baffles 3, and a feed inlet 7 and a discharge outlet 18 are provided between the baffles 3. The guide groove 17 corresponds to the feed inlet 7.

[0028] A conveyor belt 15 is provided on the upper end of the base plate 1, and the conveyor belt 15 is located below the discharge port 18;

[0029] The outer wall of the turntable 12 is provided with material troughs 14 arranged in a ring array, and the upper end of the bottom plate 1 is provided with a support plate 20 fixed to the lower end of the retaining ring.

[0030] In this embodiment, carbon steel, stainless steel, etc. are selected according to the performance requirements of the screw, and the diameter must match the final product size. The surface oxide layer is removed by pickling or mechanical rust removal, and then a lubricant is applied to reduce friction in subsequent processing. The wire is cut into blanks by a feeder, and the blanks are pre-installed inside the guide groove 17. The hydraulic rod 5 drives the push plate 16 to apply extrusion pressure to the blanks. The drive of the hydraulic rod 5 is coordinated with the motor 2. After the motor 2 rotates at an angle, the hydraulic rod 5 drives the push plate 16 to move, conveying the blanks to the material trough 14. The blanks are transferred by the rotation of the turntable 12 and the limiting of the baffle 3. After stamping, the blanks are output through the discharge port 18 and conveyed by the conveyor belt 15. This avoids the frequent loading and unloading of materials by the workers, and prevents the hands from moving directly under the stamped parts, thus improving the safety of the screw head forming process.
