Description

Technical Field

[0001] This utility model relates to the field of mold production and processing technology, specifically to a movable and convertible inclined budding stamping device. Background Technology

[0002] Angled budding stamping technology, through the angled structure design of the die or punch, decomposes the vertical main driving force of the stamping equipment into axial extrusion force and radial shear force. Utilizing the plastic flow characteristics of materials under combined stress, it achieves progressive forming in localized areas. Currently, angled budding stamping technology faces challenges in the localized forming of thin-walled parts, including material flow instability and dynamic springback control. Furthermore, the diverse range of stamped parts makes it prone to issues arising from non-compliance. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a movable and convertible inclined plane budding punching device. The punch press normally descends vertically, first pressing the semi-finished product. Then, through components such as the slider and wedge, the downward pressure of the punch press is transmitted to the budding mechanism assembly. Through force transmission, the downward pressure is converted into an upward, inclined punching force. The budding punch then reverses its direction along the inclined plane to pre-punch the workpiece.

[0004] To achieve the above objectives, a movable and convertible inclined plane budding stamping device is designed, including an upper die base and a lower die base. The upper die base is connected to an upper clamping plate, and an inclined wedge is inserted below the upper clamping plate. A pressure plate is located below the upper clamping plate, and a lower die slider is located below the pressure plate. A lower pad is connected below the lower die slider, and a lower die base is connected below the lower pad. A guide block is connected to one side of the lower die slider, and a budding stripping plate is connected to the other side of the lower die slider. A spring is horizontally embedded in the lower die slider, and the left end of the spring abuts against the guide block. An inner positioning device is inserted in the center of the lower die slider. A budding base is connected to the lower die slider, and a budding punch is connected above the budding base. The front end of the budding punch penetrates the budding stripping plate, and a spring is embedded in the budding stripping plate, with the other end of the spring abutting against the budding base.

[0005] The upper surface of the lower mold slider is provided with groove one and groove two. Groove one and groove two are respectively provided with inclined surface one and inclined surface two. Inclined surface one cooperates with the lower surface of the inclined wedge. The budding base is fixed above the inclined surface two by equal height sleeve screw one.

[0006] The upper right side of the pressure plate is connected to one end of the inner guide post via a stud. The other end of the inner guide post passes through the upper clamping plate and the inner guide post and protrudes above the inner guide post. One end of the equal height sleeve screw is inserted into the upper left side of the pressure plate. The other end of the equal height sleeve screw passes through the upper clamping plate and is fixed to the upper mold base.

[0007] The budding punch has a cylindrical structure, with a front cutting edge at the top and a rear punch in the middle section.

[0008] The upper mold base is connected to the upper support plate via an upper pad, and the lower mold base is connected to the lower support plate via a lower pad.

[0009] One end of a spring three is located on the top of the pressure plate, and the other end of the spring three passes through the upper clamping plate and the upper mold base and abuts against the upper support plate.

[0010] An external independent guide post is provided on the right side between the upper mold base and the lower mold base, an upper limit post is provided on the lower left side of the upper mold base, and a lower limit post is provided on the upper left side of the lower mold base to cooperate with the upper limit post.

[0011] Compared with the prior art, the special budding mechanism of this utility model, which converts the oblique reverse motion into the straight forward motion, can better adjust and control the budding angle and position when dealing with complex and special oblique budding, thereby taking into account both product appearance and size requirements.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1As shown, an upper clamping plate 11 is connected below the upper mold base 10. A wedge 4 is inserted below the upper clamping plate 11.

A lower mold base 13 is connected below the lower pad 12. A guide block 5 is connected to one side of the lower mold slider 1. A stripping plate 2 is connected to the other side of the lower mold slider 1. A spring 19.1 is horizontally embedded inside the lower mold slider 1. The left end of the spring 19.1 abuts against the guide block 5. The spring 19.1 can buffer the impact of the wedge 4. The impact force, and at the same time, after the workpiece is processed, the spring 19.1 can drive the lower die slider 1 to reset. The lower die slider 1 has an inner positioning 20 inserted in the center. The lower die slider 1 is connected to the budding base 6. The budding punch 7 is connected above the budding base 6. The front end of the budding punch 7 penetrates the budding stripper plate 2. The budding stripper plate 2 is embedded with the spring 2 19.2. The other end of the spring 2 19.2 abuts against the budding base 6. After forming, the budding base 6 is reset by the spring 2 19.2, separating the workpiece and the punch to prevent adhesion.

[0018] The upper surface of the lower mold slider 1 is provided with groove 1.1 and groove 1.2. Grooves 1.1 and 1.2 are respectively provided with inclined surface 23 and inclined surface 24. Inclined surface 23 fits with the lower surface of the inclined wedge 4. The budding base 6 is fixed above the inclined surface 24 by equal height sleeve screw 18.1. The inclined wedge 4 and inclined surface 23 cooperate to convert the vertical downward pressure into an inclined force, driving the lower mold slider 1 to move laterally, realizing the conversion of the budding motion trajectory.

[0019] The upper right side of the pressure plate 3 is connected to one end of the inner guide post 17 via a stud. The other end of the inner guide post 17 passes through the upper clamping plate 11 and the inner guide post 17 and protrudes above the inner guide post 17. One end of the equal height sleeve screw 18.2 is inserted into the upper left side of the pressure plate 3. The other end of the equal height sleeve screw 18.2 passes through the upper clamping plate 11 and is fixed to the upper mold base 10.

[0020] like Figure 3 As shown, the budding punch 7 has a cylindrical structure. The top of the budding punch 7 is provided with a front cutting edge 7.1, and the middle section of the budding punch 7 is provided with a rear punch 7.2. The front cutting edge 7.1 is used for pre-punching, and the rear punch 7.2 completes the budding forming. The cylindrical structure optimizes the uniformity of material stress.

[0021] The upper mold base 10 is connected to the upper support plate 8 via the upper pad 9, and the lower mold base 13 is connected to the lower support plate 15 via the lower pad 14.

[0022] One end of a spring 3 19.3 is located on the top of the pressure plate 3. The other end of the spring 3 19.3 passes through the upper clamping plate 11 and the upper die holder 10 and abuts against the upper support plate 8. The spring 3 19.3 can ensure that the pressure force is evenly distributed, prevent the workpiece from shifting during the stamping process, and also buffer the force on the equipment and extend the service life of the equipment.

[0023] An external independent guide post 16 is provided on the right side between the upper mold base 10 and the lower mold base 13. An upper limit post 21 is provided on the lower left side of the upper mold base 10, and a lower limit post 22 that cooperates with the upper limit post 21 is provided on the upper left side of the lower mold base 13.

[0024] The specific implementation process of this utility model is as follows: The technician places the workpiece to be processed flat above the lower die slider 1 and the stripper plate 2, determines the flat position through the inner positioning 20, and then starts the punch press. The punch press descends, and the pressure plate 3 first contacts and presses the workpiece to be processed. The punch press continues to descend, and the wedge 4 cooperates with the inclined surface 23 of the lower die slider 1. Under the guidance of the guide block 5, the lower die slider 1 moves along a straight line in the positive direction, and the stripper base 6 receives a downward pressure. Under the action of the stripper base 6 Downward, the front cutting edge 7.1 of the budding punch 7 pre-punches the workpiece along the oblique upward direction. As the punch press continues to descend, the rear punch 7.2 of the budding punch 7 continues to bud the workpiece. Guided by the pre-punching, the workpiece can be precisely budded, converting the vertical punching force into an oblique punching force. When the punch press descends to its dead point, the workpiece is budded on the oblique surface. At this time, springs 19.1 and 19.2 work together to buffer the impact force and reset the budding punch 7, completing the stripping process. This device achieves a single-stroke compound action, avoiding multi-station sequential processing. It can better handle complex and special oblique surface budding and better adjust and control the budding angle and position, thus taking into account both the appearance and dimensional requirements of the product.
