Description

Technical Field

[0001] This invention relates to the field of bolt processing equipment technology, and more specifically, to a punch press for manufacturing bolts. Background Technology

[0002] Bolts are one of the most widely used basic components in mechanical connections, and their manufacturing quality and production efficiency directly affect the production costs and product quality of downstream industries.

[0003] Traditional manufacturing processes generally suffer from problems such as fragmented processes, numerous pieces of equipment, and large floor space requirements for assembly lines. Traditional bolt forming typically requires separate feeding, cutting, stamping, and unloading equipment, with manual or auxiliary mechanisms needed for transfer and positioning between these devices. This not only results in long production cycles and low overall efficiency but also makes it difficult to guarantee bolt forming accuracy due to the tendency for blanks to shift or misalign during transport. Furthermore, traditional stamping dies lack effective constraint on the blanks, leading to burrs and flash on the bolt heads, resulting in inconsistent forming quality and requiring additional finishing processes, further reducing production efficiency. To address these issues, there is an urgent need to develop a highly integrated, automated bolt manufacturing equipment that provides stable forming quality. Summary of the Invention

The feeding transmission unit drives the cutting unit to cut the steel wire and feed it into the forming mold cavity 4. The stamping mechanism 7 includes a stamping transmission part and a forming part. The stamping transmission part is connected to the support frame 9, and the forming part is connected between the support frame 9 and the support frame 11. The stamping transmission part drives the forming part to stamp and form the steel wire blank in the forming mold cavity 4. The ejector mechanism 8 is connected to the support base 2 and is used to eject the formed bolt from the forming cavity 4. The integrated feeding, stamping, ejection and rotation mechanism 5 realizes the integration of the entire bolt processing process, avoids the transfer of multiple equipment, improves processing efficiency and forming accuracy, and the receiving slider 12 can effectively prevent the bolt from generating flash.

[0026] Support frame 1 (9), support frame 2 (10), and support frame 3 (11) are all fixedly connected to the top surface of the support base plate 1. This forms a stable overall support frame, ensuring the stability of each mechanism during operation and preventing displacement from affecting machining accuracy.

[0027] This invention adopts a multi-station synchronous cyclic operation mode, and the overall process is divided into three stages: feeding and cutting, stamping and forming, and ejection and collection. The device mainly consists of a rotary worktable 3, multiple forming cavities 4, a feeding and cutting station, a stamping and forming station, an ejection station, and corresponding drive mechanisms. Multiple stations are evenly arranged around the circumference of the worktable 3. The worktable 3 is equipped with multiple forming cavities 4 to accommodate blanks and define the bolt head contours. Each forming cavity 4 rotates with the worktable 3 and passes through each station in sequence to complete continuous processing. The first drive motor 13 drives the rotating mechanism 5 and the ejection mechanism 8 simultaneously through the first drive crossbar 14 to synchronize the rotation of the worktable 3 and the ejection action. The second drive motor 15 drives the stamping mechanism 7 through the second drive crossbar 16. The stamping mechanism 7 then drives the feeding mechanism 6 synchronously through belt drive, so that the feeding, cutting, and stamping actions are strictly linked to ensure consistent processing sequence.

[0028] refer to Figures 1-2 A first drive motor 13 is fixedly connected to the top surface of the support base plate 1, and a first drive crossbar 14 is fixedly connected to the output shaft of the first drive motor 13. The first drive motor 13 and the first drive crossbar 14 provide concentrated power to the rotating mechanism 5 and the material feeding mechanism 8, simplifying the power transmission structure and reducing equipment manufacturing costs and failure probability.

[0029] The rotating mechanism 5 includes a first rotating bevel gear 501, a second rotating bevel gear 502, a first mounting plate 503, a first mounting rod 504, a first transmission gear 505, and a gear ring 506. The first rotating bevel gear 501 is fixedly connected to the first drive crossbar 14. The first mounting plate 503 is fixedly connected to the side of the support base 2. The first mounting rod 504 is rotatably connected to the first mounting plate 503. The lower end of the first mounting rod 504 passes through the first mounting plate 503 and is fixedly connected to the second rotating bevel gear 502. The first rotating bevel gear 501 meshes with the second rotating bevel gear 502. The upper end of the first mounting rod 504 passes through the mounting plate and is fixedly connected to the first transmission gear 505. The gear ring 506 is fixedly connected to the outer circumferential wall of the worktable 3. The first transmission gear 505 meshes with the gear ring 506. The timing of the molding cavity 4's dwelling, processing, and rotation at each station is coordinated with the actions of the feeding mechanism 6, the stamping mechanism 7, and the ejection mechanism 8 to achieve synchronous and stable operation of the entire equipment.

[0030] Power is provided by a first drive motor 13 fixed to the support base plate 1. The output shaft of the first drive motor 13 drives the first drive crossbar 14 to rotate, and the rotating bevel gear 501 fixedly connected to the first drive crossbar 14 rotates synchronously. The rotating bevel gear 501 meshes with the rotating bevel gear 502, driving the mounting vertical rod 504 to rotate around its own axis. The upper end of the mounting vertical rod 504 drives the transmission gear 505 to rotate; the transmission gear 505 meshes with the gear ring 506 fixed on the outer circumferential wall of the worktable 3, thereby transmitting power to the worktable 3, causing the worktable 3 to rotate around its central axis.

[0031] refer to Figure 1 , Figure 5 and Figure 6 A second drive motor 15 is fixedly connected to the support frame 9. The output shaft of the second drive motor 15 is fixedly connected to a second drive crossbar 16, and the front end of the second drive crossbar 16 is rotatably connected to the support frame 9. The second drive motor 15 and the second drive crossbar 16 provide concentrated power to the stamping mechanism 7 and the feeding mechanism 6, ensuring that the action sequence of the two mechanisms is synchronized and improving the continuity of processing.

[0032] The feeding mechanism 6 includes a first transmission wheel 601, a second transmission wheel 602, a transmission belt 603, a transmission crossbar 604, a second mounting plate 605, a second mounting vertical rod 606, a first feeding bevel gear 607, a second feeding bevel gear 608, and an incomplete gear 609. The transmission crossbar 604 is rotatably connected to the first support frame 9. The first transmission wheel 601 is fixedly connected to the crank rod 703, and the second transmission wheel 602 is fixedly connected to the transmission crossbar 604. The first transmission wheel 601 and the second transmission wheel 602... The components 602 are connected by a transmission belt 603. A first feeding bevel gear 607 is fixedly connected to the front end of the transmission crossbar 604. A second mounting plate 605 is fixedly connected to a first support frame 9. A second mounting vertical rod 606 is rotatably connected to the second mounting plate 605. The upper end of the second mounting vertical rod 606 is fixedly connected to a second feeding bevel gear 608, and the first feeding bevel gear 607 meshes with the second feeding bevel gear 608. The lower end of the second mounting vertical rod 606 is fixedly connected to an incomplete gear 609. Power is transmitted through belt drive and bevel gear pairs, enabling the feeding mechanism 6 and the stamping mechanism 7 to move in tandem. The incomplete gear 609 is designed to provide power for the reciprocating motion of the cutting blade 613, simplifying the feeding transmission structure.

[0033] The feeding mechanism 6 also includes a discharge plate 610, a discharge hole 611, a cutting groove 612, a cutting blade 613, a connecting frame 614, and a reciprocating rack 615. The discharge plate 610 is fixedly connected to the support frame 10. The discharge plate 610 has a discharge hole 611 and a cutting groove 612. The discharge hole 611 vertically penetrates the discharge plate 610 and is located directly above the forming mold cavity 4. The cutting groove 612 horizontally penetrates the discharge hole 611. The cutting blade 613 is slidably connected in the cutting groove 612. The side of the cutting blade 613 is fixedly connected to the connecting frame 614. Two sets of reciprocating racks 615 are provided. The two sets of reciprocating racks 615 are fixedly connected to the front and rear inner walls of the connecting frame 614, respectively. The incomplete gear 609 meshes with the reciprocating racks 615. The billet is directly fed into the mold, with accurate positioning and no offset. The cutting is continuous and stable, eliminating manual feeding and secondary positioning, and improving feeding efficiency and consistency. The discharge hole 611 is precisely aligned with the forming mold cavity 4. The cutting groove 612 and the cutting blade 613 work together to achieve quantitative cutting of the steel wire. The reciprocating rack 615 and the incomplete gear 609 are linked to ensure uniform cutting size and accurate material dropping, thereby improving the consistency of material supply.

[0034] When the crank 703 rotates, it drives the transmission crossbar 604 to rotate via the transmission wheel 601, transmission wheel 602, and transmission belt 603. This rotation, in turn, drives the mounting vertical rod 606 to rotate via the feeding bevel gear 607 and feeding bevel gear 608, causing the incomplete gear 609 to rotate. The incomplete gear 609 alternately meshes with two sets of reciprocating racks 615 within the connecting frame 614, driving the cutting blade 613 to reciprocate linearly within the cutting groove 612. The continuous steel wire passes through the discharge hole 611 and is cut in real-time by the reciprocating cutting blade 613, forming equal-length blanks that fall directly into the corresponding forming mold cavity 4, achieving continuous automatic feeding.

[0035] refer to Figure 1 and Figure 4 The stamping mechanism 7 includes a second transmission gear 701, a reduction gear 702, a crank 703, a flywheel 704, a first connecting rod 705, a second connecting rod 706, a stamping head 707, a guide frame 708, and a guide sleeve 709. The second transmission gear 701 is fixedly connected to the second drive crossbar 16. The crank 703 is rotatably connected between a first support frame 9 and a third support frame 11. One end of the crank 703 passes through the first support frame 9 and is fixedly connected to the reduction gear 702. The second transmission gear 701 and the reduction gear 702... The two ends of the crank rod 703 are meshed, with the other end passing through the support frame 11 and fixedly connected to the flywheel 704. The upper end of the connecting rod 705 is rotatably connected to the bend of the crank rod 703, and the lower end of the connecting rod 705 is rotatably connected to the upper end of the connecting rod 706. The guide frame 708 is fixedly connected to the top surface of the support base plate 1, and the guide sleeve 709 is fixedly connected to the guide frame 708. The lower end of the connecting rod 706 passes through the guide sleeve 709 and is fixedly connected to the stamping head 707. The connecting rod 706 slides with the guide sleeve 709. The flywheel 704 ensures sufficient stamping energy and full forming. The steel wire blank and the support base 2 are separated by the receiving slider 12, so that the receiving slider 12, which is in close contact with the forming mold cavity 4, and the steel wire blank are in contact, effectively avoiding burrs and flash on the bolts, improving forming accuracy and surface quality, and reducing subsequent finishing processes.

[0036] The forming cavity 4, containing the blank, rotates with the rotary table 3 to below the stamping mechanism 7. The second drive motor 15 drives the crank 703 to rotate through the transmission gear 701 and the reduction gear 702. The crank 703 drives the connecting rod 705 and the connecting rod 706 to move, so that the stamping head 707 performs vertical reciprocating stamping motion under the constraint of the guide sleeve 709. A flywheel 704 is provided at the end of the crank 703, which provides sufficient and stable stamping energy by utilizing the inertia of the flywheel 704 to ensure full forming. The forming cavity 4 is provided with a receiving slider 12, which fits tightly against the inner wall of the cavity. During the stamping process, it constrains the blank around the entire circumference, restricting the outward flow of metal, thereby avoiding the formation of burrs and flash on the bolt head.

[0037] refer to Figures 1-4The ejector mechanism 8 includes an ejector cam 801, a connecting spring 802, a connecting telescopic rod 803, a connecting horizontal plate 804, an ejector rod 805, and an ejector hole 806. The front end of the first driving horizontal rod 14 passes through the support base 2 and is fixedly connected to the ejector cam 801. The support base 2 has an ejector hole 806, the position of which corresponds to the position of the forming cavity 4. There are two sets of connecting springs 802 and connecting telescopic rods 803. The upper ends of connecting springs 802 and connecting telescopic rods 803 are fixedly connected to the bottom surface of the support base 2, and the lower ends of connecting springs 802 and connecting telescopic rods 803 are fixedly connected to the connecting horizontal plate 804. The ejector rod 805 is fixedly connected to the connecting horizontal plate 804 and extends upward. The top end of the ejector rod 805 passes through the ejector hole 806. The connecting horizontal plate 804 abuts against the peripheral side of the cam. The cam-driven ejector rod 805, in conjunction with the spring reset, enables the bolt to be automatically ejected and reset reliably. The ejector hole 806 is set to correspond with the forming mold cavity 4 to ensure accurate ejection and avoid damage to the forming bolt.

[0038] The ejection mechanism 8 also includes a baffle 807 and a guide chute 808, both of which are fixedly connected to the support frame 9. The ejection mechanism responds quickly, ensuring smooth and unobstructed material discharge, achieving automatic detachment and centralized collection of the molded parts, thus improving discharge stability and automation. The addition of the baffle 807 and guide chute 808 guides and limits the ejected bolts, enabling automatic collection, preventing bolt scattering and impact, and improving discharge stability.

[0039] After molding, the bolt rotates with the worktable 3 to the ejection station. The first drive crossbar 14 drives the ejector cam 801 to rotate, the cam lifts the connecting crossbar 804, causing the ejector rod 805 to move upward along the ejector hole 806, pushing the receiving slider 12 to slide upward, ejecting the molded bolt from the molding cavity 4; the connecting crossbar 804 falls back along the cam profile under the action of the connecting spring 802 and the connecting telescopic rod 803, realizing the automatic reset of the ejector rod 805. The ejected bolt slides out of the equipment along the guide groove 808 under the limiting and guiding action of the baffle 807, completing the automatic collection.
