Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of thread rolling machine technology, and more specifically, to a high-speed thread rolling machine for bolt production. Background Technology

[0002] Anchor bolts are a type of fastener consisting of a head and a shank (a cylinder with external threads). They are used in conjunction with nuts to fasten two parts with through holes. In the production of bolts, high-speed thread rolling machines are used to roll the threads on the bolt blanks. Thread rolling machines are specialized equipment for producing screws and are mainly used in the fields of machinery manufacturing, automobiles, aerospace, and mold processing. They adopt a cold forming process using thread rolling plates, and the thread processing is achieved through the reciprocating motion of two parallel thread rolling plates. The thread accuracy can reach level two. Compared with traditional lathe tapping, it has the characteristics of being lightweight and flexible, highly efficient, and having low tap wear. In existing high-speed thread rolling machines for bolt production, the threaded bolts roll directly out of the machine through a discharge frame and fall directly onto the ground. After multiple bolts have been threaded, they are scattered haphazardly on the ground. Currently, a receiving box is used to collect the bolts after they are discharged, but the bolts inside the receiving box are quite messy, requiring workers to re-sort them afterward, which increases the workload of the workers.

The protective shell is provided with a drive component for driving the turntable to rotate. The drive component is a forward and reverse rotating motor. The T-shaped transmission seat is installed on one of the two sides of the turntable and is located inside the slide groove. When the turntable drives the T-shaped transmission seat to rotate, the swing hammer can be driven to swing through the sliding of the T-shaped transmission seat inside the slide groove.

[0006] As a preferred embodiment of the high-speed thread rolling machine for bolt production described in this utility model, in order to achieve buffering between the swing hammer and the receiving table and avoid direct impact between the swing hammer and the receiving table, a buffer pad is provided on the hammer head of the swing hammer.

[0007] In a preferred embodiment of the high-speed thread rolling machine for bolt production described in this utility model, in order to limit the movement of the L-shaped adjusting plate and ensure the stability of the L-shaped adjusting plate during movement, square blocks are installed on both sides of the inner wall of the receiving box, and square grooves are opened on both sides of the L-shaped adjusting plate. The L-shaped adjusting plate is sleeved on the square blocks through the square grooves.

[0008] In a preferred embodiment of the high-speed thread rolling machine for bolt production described in this utility model, in order to block and limit the connecting seat and prevent the connecting seat from detaching from the guide post, a limiting plate is installed on one side of the guide post, and a rubber ring is provided on the side of the limiting plate near the guide post.

[0009] As a preferred embodiment of the high-speed thread rolling machine for bolt production described in this utility model, in order to limit the movement of the connecting seat and ensure the stability of the connecting seat during movement, a T-shaped block is installed on the lower side of the connecting seat, and multiple T-shaped grooves are opened on the inner bottom wall of the L-shaped adjusting plate, the width of the T-shaped grooves being adapted to the width of the T-shaped block.

[0010] As a preferred embodiment of the high-speed thread rolling machine for bolt production described in this utility model, in order to achieve orderly arrangement of bolts falling onto the receiving platform, the receiving platform is trapezoidal in shape, and the installed receiving platform is located directly below the discharge port.

[0011] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the trapezoidal design of the receiving platform allows the bolts falling onto the receiving platform to roll in an orderly manner, thus enabling the bolts to be arranged in an orderly manner on the receiving platform. Through the cooperation between the L-shaped adjusting plate, the connecting seat and the mounting plate, the receiving platform can be quickly installed or disassembled, allowing the staff to quickly replace the receiving platform and ensuring the receiving platform's bolt receiving effect.

[0021] like Figures 1-5 As shown, this invention illustrates a high-speed thread rolling machine for bolt production according to an embodiment of the present disclosure. The machine includes a main body 1, with a receiving box 2 mounted on one side of the main body 1 via a support plate. The receiving box 2 has a discharge port on its upper side. It also includes an L-shaped adjusting plate 3, a guide post 4, a connecting seat 5, a return spring 6, a mounting plate 7, a receiving platform 8, and a swinging striking mechanism. Compared to existing high-speed thread rolling machines for bolt production, which struggle to neatly arrange bolts after discharge, this embodiment addresses this issue by using a trapezoidal design for the receiving platform 8. This design allows the bolts falling onto the receiving platform 8 to roll orderly, thus ensuring the bolts are properly positioned on the receiving platform 8. The bolts are arranged in an orderly manner. Through the cooperation between the L-shaped adjusting plate 3, the connecting seat 5 and the mounting plate 7, the bolt docking platform 8 can be quickly installed or disassembled, allowing the staff to quickly replace the bolt docking platform 8 and ensuring the receiving effect of the bolt docking platform 8 on the bolts. Through the cooperation between the guide post 4, the connecting seat 5, the return spring 6, the mounting plate 7 and the swinging and tapping mechanism, the swinging and tapping of the bolt docking platform 8 is realized. This allows the staff to swing and tap the bolt docking platform 8 when the bolts get stuck on the rolling of the bolts, reducing the probability of the bolts getting stuck on the bolt docking platform 8 and affecting the normal rolling of other bolts, and ensuring the smooth rolling of the bolts on the bolt docking platform 8. like Figure 1 As shown, the L-shaped adjusting plate 3 is provided with an observation window 9. The observation window 9 can be used to observe the number of bolts placed on the material receiving platform 8, so that the staff can replace the material receiving platform 8 in a timely manner. A baffle frame 10 is installed on the upper side of the receiving box 2. The baffle frame 10 covers the upper side of the discharge port. The baffle frame 10 can block the bolts rolling off the discharge frame, so that the bolts can fall into the discharge port better. like Figure 1 and Figure 2 As shown, the L-shaped adjusting plate 3 is inserted into the receiving box 2. The L-shaped adjusting plate 3 is fixed to the receiving box 2 by bolts. Square blocks are installed on both sides of the inner wall of the receiving box 2. Square slots are opened on both sides of the L-shaped adjusting plate 3. The L-shaped adjusting plate 3 is fitted onto the square blocks through the square slots. The square blocks can limit the movement of the L-shaped adjusting plate 3 through the square slots, thus ensuring the stability of the L-shaped adjusting plate 3 during movement. Two guide posts 4 are installed at the bottom of the inner wall of the L-shaped adjusting plate 3. A limiting plate is installed on one side of the guide post 4. A rubber ring is set on the side of the limiting plate near the guide post 4. The limiting plate can block and limit the connecting seat 5 on the guide post 4, preventing the connecting seat 5 from detaching from the guide post 4. The two guide posts 4 are symmetrically arranged, as shown. Figure 3 and Figure 4As shown, a connecting seat 5 is sleeved on the guide post 4, and a T-shaped block is installed on the lower side of the connecting seat 5. Multiple T-shaped grooves are formed on the inner bottom wall of the L-shaped adjusting plate 3. The width of the T-shaped grooves matches the width of the T-shaped blocks. The L-shaped adjusting plate 3 can limit the movement of the connecting seat 5 through the T-shaped blocks and T-shaped grooves, thus ensuring the stability of the connecting seat 5 during movement. A return spring 6 is sleeved on the guide post 4, and its two ends are connected to the guide post 4 and the connecting seat 5 respectively. A mounting plate 7 is inserted into the upper side of the connecting seat 5 and fixed to the connecting seat 5 by bolts. A receiving platform 8 is installed on the upper side of the mounting plate 7. The receiving platform 8 is trapezoidal in shape. The receiving platform 8 is located directly below the material discharge port. The trapezoidal design of the receiving platform 8 allows the bolts falling into it to roll in an orderly manner, thus ensuring that the bolts are arranged in an orderly manner on the receiving platform 8. The cooperation between the L-shaped adjusting plate 3, the connecting seat 5, and the mounting plate 7 enables the quick installation or removal of the receiving platform 8, allowing workers to quickly replace the receiving platform 8. The cooperation between the guide post 4, the connecting seat 5, the return spring 6, and the mounting plate 7 enables the automatic return of the receiving platform 8, ensuring that the receiving platform 8 inside the receiving box 2 remains below the material discharge port. like Figure 2 As shown, the oscillating striking mechanism is located inside the receiving box 2, as... Figure 5 As shown, the swinging striking mechanism includes a swing assembly and a drive assembly. The swing assembly includes a hinge seat 101, a swing hammer 102, and a slide 1021. The drive assembly includes a mounting plate 201, a protective shell 202, a turntable 203, and a T-shaped transmission seat 204. A buffer pad is provided on the hammer head of the swing hammer 102. The buffer pad can buffer the swing hammer 102 and the receiving platform 8, avoiding collision between the swing hammer 102 and the receiving platform 8, and extending the service life of the receiving platform 8. The swinging striking mechanism can realize the swinging striking of the receiving platform 8, and can make the bolts that are stuck on the receiving platform 8 roll again, ensuring the smooth rolling of the bolts on the receiving platform 8.

[0022] Working principle: When the bolts processed by the main body 1 of the thread rolling machine are discharged from the discharge frame, the bolts roll down through the discharge frame to the discharge port on the upper side of the receiving box 2, and then fall from the discharge port to the trapezoidal receiving platform 8. The bolts roll on the receiving platform 8, rolling from the top to the bottom. After subsequent processing, the bolts that fall onto the receiving platform 8 roll in an orderly manner on the receiving platform 8, realizing the orderly arrangement of multiple bolts. When the bolt gets stuck while rolling on the receiving table 8, the main body 1 of the thread rolling machine is shut down, and the forward and reverse motor is started. The forward and reverse motor drives the turntable 203 to rotate. When the turntable 203 drives the T-shaped transmission seat 204 to rotate synchronously, the T-shaped transmission seat 204 slides inside the slide groove 1021, causing the swing hammer 102 to swing. During the swinging process, the swing hammer 102 strikes the receiving table 8. The bolt stuck on the receiving table 8 is affected by the strike and rolls again on the receiving table 8. The receiving table 8 is displaced by the strike. The receiving table 8 drives the connecting seat 5 to move along the guide post 4 through the mounting plate 7. The connecting seat 5 compresses the return spring 6. When the strike of the swing hammer 102 on the receiving table 8 disappears, the receiving table 8 returns to its original position under the action of the return spring 6. When there are too many bolts on the receiving platform 8 and the receiving platform 8 needs to be replaced, the worker turns the bolts used to fix the receiving box 2 and the L-shaped adjusting plate 3 counterclockwise to remove the bolts fixing the receiving box 2 and the L-shaped adjusting plate 3. After removal, the worker pulls the L-shaped adjusting plate 3 out of the receiving box 2. The L-shaped adjusting plate 3 drives the receiving platform 8 to move out of the receiving box 2 at the same time. Then, the worker turns the bolts used to fix the connecting seat 5 and the mounting plate 7 counterclockwise to remove the bolts fixing the connecting seat 5 and the mounting plate 7. After removal, the worker removes the receiving platform 8 from the connecting seat 5 and then installs the new receiving platform 8 on the connecting seat 5, thus completing the replacement of the receiving platform 8.
