Description

Technical Field

[0001] This utility model relates to the field of dual-station hardware mold technology, and in particular to a dual-station cold extrusion hardware mold. Background Technology

[0002] A dual-station hardware mold is a type of mold used for stamping processing. Its core feature is that it integrates two stations (workstations) within one mold, completing two different processes in one stamping stroke. The mold contains two independent processing areas (stations), and the automatic transfer of materials between different stations is usually achieved through a feeding mechanism or a rotary table.

[0003] For some hardware bending operations, a single stamping is insufficient to directly form parts of the required size, thus requiring two stamping operations. Traditional mold structures are relatively bulky and complex to adjust. Therefore, a dual-station cold extrusion hardware mold is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a dual-station cold extrusion hardware mold, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of the present invention provides a dual-station cold extrusion hardware mold, including a T-shaped base, two horizontally placed guide rails installed on the side of the base, and a horizontally sliding die mounting seat installed inside the two guide rails. The two die mounting seats are stepped in shape, and a die is installed at each step position. Two lower supports are installed on the bottom surface of the inner wall of the base, and height adjustment components are threaded on the top of both supports. The top of each of the two height adjustment components is threaded to an upper support, and the top of each of the two upper supports is fixedly connected to the bottom surface of the two guide rail overhang positions respectively. Both sides of the top surface of the base are equipped with vertically placed pneumatic cylinders, and both of them have punch mounting seats installed at their output ends. The bottom surfaces of the two punch mounting seats are equipped with punches.

[0006] Preferably, as described in any of the above solutions, the base has two mounting slots on its side, and each mounting slot has a connecting plate installed on its bottom wall. The two connecting plates are fixedly connected to the center of the bottom surface of the guide rail by bolts. This solution facilitates the provision of mounting positions for the two guide rails. The ends of the two guide rails away from the base are designed with openings and have a stepped structure, thereby avoiding interference with the engagement of the punch and die and ensuring stability during part processing. The two connecting plates are made of steel plate profiles, and their top surfaces are on the same plane. The bottom surface of the guide rail in the middle is thickened and then fixedly connected to the connecting plates by bolts, facilitating initial installation and subsequent replacement.

[0007] Preferably, in any of the above solutions, a limiting frame is installed on the side of the base near the mounting slot, and limiting posts are installed on both sides of the top surface of the two punch mounting seats. The four limiting posts are slidably connected to the ends of the limiting frames. In this solution, one end of the two limiting frames is fixedly connected to the side of the base by bolts, which facilitates the stable installation of the limiting frames. The slidable connection between the limiting posts and one end of the limiting frames facilitates the limitation of the vertical movement of the two punch mounting seats. The punch is installed on the bottom surface of the punch mounting seat by bolts. After the pneumatic cylinder extends, it pushes the punch mounting seat and the punch to move vertically downward, so that the punch cooperates with the die at the designated position, which facilitates the stamping operation of the hardware parts.

[0008] Preferably, in any of the above solutions, two servo motors are installed on the side of the base near the mounting slot, and drive gears are installed on the output ends of both motors. Racks are installed on adjacent sides of the two die mounting seats. Through slots are opened on the sides of the two guide rails near the drive gears. The two drive gears pass through the through slots and mesh with the racks. This solution facilitates the formation of a precise drive structure. The two servo motors are controlled by an external servo controller, which has high control accuracy. The whole system is controlled by a PLC. Through parameter settings, the PLC can control the servo motors to rotate by a specified angle through the servo controller, driving the die mounting seats to move a specified distance, so that the die and punch are aligned vertically, improving the accuracy of subsequent stamping.

[0009] The bottom ends of the adjacent sides of the two guide rails are recessed inward to provide a mounting position for the rack. The through slots on both sides of the guide rails allow the rack to be exposed and the drive gear to mesh with the rack, thereby driving the two die mounting seats to move horizontally and change the position of different dies. The variable position is more numerous and meets the stamping processing of hardware parts of different sizes.

[0010] Preferably, in any of the above embodiments, both height adjustment components include double-ended studs, with adjusting nuts threaded to both sides of the middle portion of the double-ended stud. The threads at both ends of the double-ended stud rotate in opposite directions and are threaded to the upper and lower supports, respectively. This design facilitates relative rotation between the two ends of the double-ended stud and the upper and lower supports by rotating the stud, thereby providing stable support for the upper support. Subsequently, the two adjusting nuts are turned with a wrench to lock the mating positions of the double-ended stud with the upper and lower supports, thus providing stable support for the overhanging portion of the guide rail. It also serves to withstand the impact force during the stamping process of the parts, ensuring the overall smooth operation.

[0011] This utility model has the following advantages: 1. This dual-station cold extrusion hardware mold, by setting two guide rails, a servo motor and a die mounting base, the die mounting base is slidably connected to the guide rails, a rack is installed on the side of the die mounting base, and a drive gear meshing with the rack is installed on the output end of the servo motor. Thus, by energizing the servo motor to rotate forward and reverse, the die mounting base is driven to move horizontally, changing the position of different dies. By installing the corresponding punch on the punch mounting base, it is convenient to use two pneumatic cylinders to alternately extend, so that the punches and dies at different positions can cooperate, and the parts can be stamped on different punches and dies. The overall structure is simple, the mold is easy and quick to change, and it effectively solves the problems existing in the prior art.

[0012] 2. This dual-station cold extrusion hardware mold features two limiting frames and two punch mounting seats. Each punch mounting seat has a limiting post mounted on its top surface. The four limiting posts are slidably connected to the limiting frames, thus guiding the vertical movement of the punch mounting seats and aligning the punch and die vertically. An upper support, a lower support, and a height adjustment assembly are threaded together. Rotating the height adjustment assembly provides stable support for the overhanging portion of the guide rail and withstands the impact force during stamping, ensuring the stability of the parts during the stamping process.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0016] like Figures 1 to 6 As shown, a dual-station cold extrusion hardware mold includes a T-shaped base 1. Two horizontally placed guide rails 9 are installed on the side of the base 1, and a horizontally sliding die mounting seat 5 is installed inside the two guide rails 9. The two die mounting seats 5 are stepped in shape, and a die is installed at each step position. Two lower supports 2 are installed on the bottom surface of the inner wall of the base 1, and height adjustment components 4 are threaded on the top of both. Three support legs are installed on the outer wall of the two lower supports 2. The bottom ends of the three support legs are fixedly connected to the base 1 by bolts, thereby locking the position of the two lower supports 2. The top ends of the two height adjustment components 4 are threadedly connected to upper supports 3. The top ends of the two upper supports 3 are fixedly connected to the bottom surface of the overhanging position of the two guide rails 9 respectively. Both sides of the top surface of the base 1 are equipped with vertically placed pneumatic cylinders 8, and both of them are equipped with punch mounting seats 6 at their output ends. The bottom surfaces of the two punch mounting seats 6 are equipped with punches.

[0017] When installing the base 1, a level must be used to measure and ensure that the bottom surface of the base 1 is horizontal and the middle is vertically upward. This facilitates the installation of the guide rails 9 inside the two mounting slots 14 and fixes them with bolts, thereby providing the two guide rails 9 with the installation positions for the two mold mounting seats 5.

[0018] The base 1 has two mounting slots 14 on its side. The bottom wall of each mounting slot 14 is fitted with a connecting plate. The two connecting plates are fixedly connected to the middle of the bottom surface of the guide rail 9 by bolts. As an optional technical solution of this utility model, this facilitates the provision of installation positions for the two guide rails 9. The ends of the two guide rails 9 away from the base 1 are designed with openings and have a stepped structure, thereby avoiding interference with the fit of the punch and die and ensuring the stability of the parts during processing. The two connecting plates are made of steel plate profiles, and the top surfaces of the two are on the same plane. The bottom surface of the middle part of the guide rail 9 is thickened and then fixedly connected to the connecting plate by bolts, which facilitates the initial installation and subsequent replacement.

[0019] A limiting bracket 7 is installed on the side of the base 1 near the mounting slot 14. Limiting posts 10 are installed on both sides of the top surface of the two punch mounting seats 6. The four limiting posts 10 are slidably connected to the ends of the limiting bracket 7. As an optional technical solution of this utility model, one end of the two limiting brackets 7 is fixedly connected to the side of the base 1 by bolts, which facilitates the stable installation of the limiting brackets 7. The limiting posts 10 are slidably connected to one end of the limiting brackets 7, which facilitates the vertical movement of the two punch mounting seats 6. The punch is installed on the bottom surface of the punch mounting seat 6 by bolts. After the pneumatic cylinder 8 extends, it pushes the punch mounting seat 6 and the punch to move vertically downward, so that the punch cooperates with the die at the designated position, which facilitates the stamping operation of the hardware parts.

[0020] Two servo motors 13 are installed on the other side of the base 1 near the mounting slot 14, and drive gears 11 are installed on the output ends of both. Racks 12 are installed on the adjacent sides of the two die mounting seats 5. Through slots are opened on the sides of the two guide rails 9 near the drive gears 11. The two drive gears 11 pass through the through slots and mesh with the racks 12. As an optional technical solution of this utility model, this facilitates the formation of a precise drive structure. The two servo motors 13 are controlled by an external servo controller, which has high control accuracy. The whole system is controlled by a PLC. Through parameter settings, the PLC can control the servo motors 13 to rotate a specified angle through the servo controller, drive the die mounting seats 5 to move a specified distance, so that the die and punch are aligned vertically, and improve the accuracy of subsequent stamping.

[0021] The bottom ends of the adjacent sides of the two guide rails 9 are recessed inward to provide a mounting position for the rack 12. The through slots on both sides of the guide rails 9 allow the rack 12 to be exposed and the drive gear 11 to mesh with the rack 12, thereby driving the two die mounting seats 5 to move horizontally and change the position of different dies. The variable position is more numerous and meets the stamping processing of hardware parts of different sizes.

[0022] Both height adjustment components 4 include double-ended studs 401. Adjusting nuts 402 are threadedly connected to both sides of the middle portion of the double-ended stud 401. The threads at both ends of the double-ended stud 401 rotate in opposite directions and are threadedly connected to the upper support 3 and the lower support 2, respectively. As an optional technical solution of this utility model, this facilitates relative rotation between the two ends of the double-ended stud 401 and the upper and lower supports 3 and 2, thereby facilitating stable support of the upper support 3. Then, by using a wrench to rotate the two adjusting nuts 402, the mating positions of the double-ended stud 401 with the upper and lower supports 3 and 2 are locked, thus facilitating stable support of the overhanging portion of the guide rail 9. Simultaneously, it is used to bear the impact force during the stamping process of the parts, ensuring overall operational stability.

[0023] This type of dual-station cold extrusion hardware mold requires the following steps for use: 1) When in use, install multiple dies of different sizes on the die mounting base 5, and install the punch of the specified size on the punch mounting base 6. 2) Control the two servo motors 13 to be powered on and run, drive the two die mounting bases 5 to move horizontally, so that the die of the specified size moves directly below the punch; 3) The operator places the hardware blank on a die, controls the extension of the pneumatic cylinder 8 at this position, pushes the punch down the height, and performs the first stamping of the hardware. After completion, the pneumatic cylinder 8 shortens and resets. 4) The operator transfers the metal parts processed in one step to another die, controls the extension of the pneumatic cylinder 8 at this position, pushes the punch to descend, and performs a second stamping on the metal parts.

[0024] In summary, during operation, the user utilizes two guide rails 9, a servo motor 13, and a die mounting base 5. The die mounting base 5 is slidably connected to the guide rails 9. A rack 12 is mounted on the side of the die mounting base 5. A drive gear 11 meshing with the rack 12 is mounted on the output end of the servo motor 13. By energizing the servo motor 13 and causing it to rotate forward and backward, the die mounting base 5 is driven to move horizontally, changing the position of different dies. By mounting the corresponding punches on the punch mounting base 6, the alternating extension of two pneumatic cylinders 8 facilitates the engagement of punches and dies at different positions, allowing the part to undergo stamping processing on different punches and dies. The structure is simple, the mold can be changed quickly and easily, and it effectively solves the problems existing in the prior art. By setting two limit frames 7 and two punch mounting seats 6, and the top surface of each punch mounting seat 6 is equipped with limit posts 10, the four limit posts 10 are slidably connected to the limit frames 7, which facilitates the vertical movement of the punch mounting seats 6 and makes the punch and die aligned vertically. By setting an upper support 3, a lower support 2 and a height adjustment component 4, the three are threadedly connected. By rotating the height adjustment component 4, the cantilevered part of the guide rail 9 can be stably supported and the impact force during the stamping of parts can be borne, ensuring the stability of the parts during the stamping process.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
