Abstract

This utility model discloses an automatic unloading mechanism for a continuous stamping die, relating to the field of stamping die unloading structures. This automatic unloading mechanism for a continuous stamping die includes a lower die base fixed to a frame. Four uprights are fixed to the four corners of the top surface of the lower die base. A support plate is fixed to the top of the four uprights. A cylinder is fixedly installed on the top surface of the support plate, with the extended end of the cylinder penetrating the support plate and extending below it. This automatic unloading mechanism utilizes the inclined surface of the drive bar to push the cylinder and drive the unloading push sleeve to avoid the punch when the upper die is closed. When the die is opened, a second spring pulls the unloading push sleeve to push out the part, which then slides down guided by a guide rail. This eliminates the need for manual unloading, achieving automatic unloading of the formed parts, solving the problem of reliance on manual unloading in existing technologies, and improving production efficiency and production line continuity.

Description

Technical Field

[0001] This utility model relates to the field of blanking structure for stamping dies, and in particular to an automatic blanking mechanism for continuous stamping dies. Background Technology

[0002] There is a side-push stamping die that can achieve a composite processing of axial pressing and lateral forming of the substrate, and complete the precise forming of parts through structures such as wedges and side-pressing sliders.

[0003] However, after forming, the parts often rise synchronously with the upper die because they are wrapped around the outside of the punch. Existing technology relies on manual removal of the parts from the punch for unloading, which increases the number of manual operation steps and is also prone to unstable unloading efficiency due to manual intervention. It is difficult to adapt to the needs of continuous and automated batch production, and affects the continuity of operation and production efficiency of the entire stamping production line. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an automatic unloading mechanism for continuous stamping dies, which solves the problem that traditional side-push stamping dies require manual unloading.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows: An automatic unloading mechanism for a continuous stamping die includes a frame, a lower die base on the top surface of the frame, an upper die plate above the lower die base that can be adapted to fit the die, a punch for forming parts on the bottom surface of the upper die plate, and an unloading component between the upper die plate and the lower die base. The unloading component is linked with the opening and closing action of the upper die plate and the lower die base to complete the unloading of the parts. The unloading assembly includes at least a pusher structure for pushing the part to separate from the punch, a drive structure for driving the pusher structure, and a guide unloading structure for guiding the part to slide down. The pusher structure is located on the upper mold plate, the drive structure is located on the lower mold base and is adapted and linked with the pusher structure, and the guide unloading structure is located on the upper mold plate and corresponds to the part separation path.

[0006] Optionally, the pushing structure includes a sliding member slidably mounted on the bottom surface of the upper template. A blanking push sleeve adapted to the shape of the punch is fixed at one end of the sliding member near the punch. An elastic member for driving the sliding member to reset is connected between the sliding member and the upper template. Specifically, the sliding member is a horizontally placed regular hexagonal prism, and the elastic member is a second spring. The second spring is sleeved on one end of the regular hexagonal prism away from the blanking push sleeve, and the two ends of the second spring are respectively fixed to the outer wall of the regular hexagonal prism and the outer wall of the upper template.

[0007] Optionally, the driving structure includes a driving bar fixed to the top surface of the frame. The top surface of the driving bar is inclined. A horizontally placed cylinder is fixed to one end of the regular hexagonal prism away from the unloading push sleeve. When the upper mold plate and the lower mold base separate, the cylinder is located directly above the inclined surface of the driving bar. During the mold closing process, the cylinder slides along the inclined surface of the driving bar, causing the unloading push sleeve to slide off the punch to expose the punch. A clearance cavity is formed in the middle of the driving bar, which is directly opposite the regular hexagonal prism and the second spring.

[0008] Optionally, the guide unloading structure includes an inclined guide rail fixed to the bottom surface of the upper template. The position of the guide rail corresponds to the falling path of the part after separation. The lower mold base is provided with a relief groove opposite to the guide rail. When the mold is closed, the guide rail is embedded in the relief groove.

[0009] Compared with the prior art, the advantages of this utility model are as follows: This invention features a regular hexagonal prism, a blanking ejector sleeve, and a second spring on the upper mold plate. These elements, along with the drive bar of the lower mold base and the inclined guide rail of the upper mold plate, allow the drive bar's inclined surface to push the cylinder during mold closing, causing the blanking ejector sleeve to avoid the punch. During mold opening, the second spring pulls the blanking ejector sleeve out of the part, which then slides down guided by the guide rail. This eliminates the need for manual blanking, achieving automatic blanking of molded parts, solving the problem of reliance on manual blanking in existing technologies, and improving production efficiency and production line continuity.

[0010] This invention transforms the lifting motion of the upper die into the sliding motion of the unloading push sleeve by setting up a mechanical linkage structure. This makes the unloading action and the stamping die opening and closing action mechanically linked, eliminating the need for additional control components. This simplifies the equipment structure while ensuring that the unloading action and the stamping process are synchronized, improving the stability and reliability of the mechanism and reducing equipment maintenance costs.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 6 This embodiment provides an automatic unloading mechanism for a continuous stamping die, including a lower die base 2 fixed on a frame 1. Uprights 3 are fixed at each of the four corners of the top surface of the lower die base 2. A support plate 4 is fixed to the top of the four uprights 3. A cylinder 5 is fixedly installed on the top surface of the support plate 4. The extended end of the cylinder 5 passes through the support plate 4 and extends below it, with an upper die plate 6 fixedly connected to the extended end. The four uprights 3 slide through the four corners of the upper die plate 6 via sliding holes. By driving the cylinder 5 to extend or retract, the upper die plate 6 can be lowered to close with the lower die base 2, or it can be raised to separate from the lower die base 2, thus realizing the opening and closing control of the stamping action.

[0020] The lower mold base 2 is also provided with two side pressure sliders 201. The top surface of the side pressure slider 201 is provided with a workpiece positioning cavity. The side pressure slider 201 is slidably connected to the lower mold base 2 through the guide column 202. The outer side of the guide column 202 is provided with a reset first spring 203. The two ends of the reset first spring 203 are fixed to the outer wall of the guide column 202 and the outer wall of the lower mold base 2, respectively. The upper mold plate 6 has a punch 601 fixed in the middle of the bottom surface, and two wedges 602 corresponding to the side pressure sliders 201 are fixed on both sides of the bottom surface. During the stamping operation, the substrate to be processed is first placed in the workpiece positioning cavity of the two side pressure sliders 201 to complete the pre-positioning of the substrate. Then, the drive cylinder 5 extends and pushes the upper template 6 down along the guide rod 3. The punch 601 in the middle of the bottom surface of the upper template 6 first contacts the substrate and performs stamping, causing the substrate to bend under the pressure of the punch 601 and gradually squeeze into the gap between the two side pressure sliders 201.

[0021] As the upper template 6 continues to descend, the wedges 602 on both sides of its bottom surface move down synchronously until the inclined surfaces of the wedges 602 contact the inclined surfaces of the side pressure sliders 201 and generate a pushing effect, forcing the two side pressure sliders 201 to slide along the guide column 202 toward each other (at this time, the reset first spring 203 is compressed) until the side pressure sliders 201 complete the lateral extrusion of the substrate, so that the substrate is fully formed and wrapped around the outside of the punch 601.

[0022] After molding, the drive cylinder 5 retracts, causing the upper template 6 to rise and reset along the upright 3. The wedge 602 moves upward and disengages from the inclined surface of the side pressure slider 201. At this time, the reset first spring 203 releases its elastic force, pushing the guide column 202 to drive the side pressure slider 201 to slide and reset in the opposite direction. The molded part, because it is wrapped around the punch 601, will rise synchronously with the punch 601, preparing for subsequent material cutting.

[0023] To achieve automatic unloading of the molded parts, a regular hexagonal prism 7 is slidably installed in the middle of one side of the bottom surface of the upper template 6. The regular hexagonal prism 7 is horizontally positioned, with its end facing the punch 601. A blanking push sleeve 8 is fixed on the side of the regular hexagonal prism 7 near the punch 601. After the blanking push sleeve 8 slides towards the punch 601, the cylindrical part 14 of the punch 601 can be precisely inserted into the blanking push sleeve 8. In this way, the molded parts fitted on the outside of the punch 601 can be pushed out by the blanking push sleeve 8, so that the parts are separated from the punch 601 for unloading. The end of the regular hexagonal prism 7 opposite to the punch 601 is fitted with... The second spring 9 has its two ends fixed to the outer wall of the regular hexagonal prism 7 and the outer wall of the upper template 6, respectively. Under the action of the second spring 9, the blanking push sleeve 8 can be kept on the outside of the punch 601. After the formed part is pushed out, the second spring 9 is in the normal state. Pulling the blanking push sleeve 8 away from the punch 601 will allow the blanking push sleeve 8 to slide to one side of the punch 601. At this time, the second spring 9 is stretched and stored. It should be emphasized that after the upper template 6 descends and the lower mold base 2 is stamped and closed, the blanking push sleeve 8 is between the upper template 6 and the lower mold base 2.

[0024] To automatically pull the blanking pusher 8 towards the side of the punch 601 during the descent of the upper mold plate 6, a drive bar 10 is fixed on the top surface of the frame 1 near the side of the regular hexagonal prism 7. The top surface of the drive bar 10 is inclined, and the side of the drive bar 10 away from the side pressure slider 201 is longitudinally straight. A horizontally placed cylinder 14 is fixed on the side of the regular hexagonal prism 7 away from the blanking pusher 8. When the upper mold plate 6 and the lower mold base 2 are in the mold separation state, the cylinder 14 is located directly above the inclined surface of the drive bar 10. During the mold closing process, the cylinder 14 descends and gradually contacts the inclined surface of the drive bar 10, and a clearance is formed in the middle of the drive bar 10. The hexagonal prism 7 and the second spring 9 will enter the clearance cavity 11. Finally, under the pushing action of the inclined surface of the drive bar 10, the blanking push sleeve 8 will be pulled to slide towards the side of the punch 601. After the punch 601 is completely exposed to the blanking push sleeve 8, the cylinder 14 will reach the longitudinal straight surface of the drive bar 10. Then the upper template 6 will continue to descend a certain distance, and the punch 601 will then stamp the part to perform the forming work. After the forming is completed, the upper template 6 will rise. Under the action of the rebound force of the second spring 9, the hexagonal prism 7 will be pulled to slide, pushing the blanking push sleeve 8 into the outside of the punch 601 until the formed part is separated.

[0025] In order to guide the unloading of the molded parts after they are detached, an inclined guide rail 12 is fixed in the middle of the bottom surface of the upper mold plate 6 on the side opposite to the regular hexagonal prism 7, and a relief groove 13 is provided in the position of the lower mold base 2 opposite to the guide rail 12. When the mold is closed, the guide rail 12 is embedded in the relief groove 13, and after the molded parts are pushed to separate from the punch 601, the parts fall onto the guide rail 12 and slide to one side along the guide rail 12, so as to achieve the effect of automatic unloading.

[0026] 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.
