Technical Problem

[0002]卡箍骨架的普通折弯工艺在操作时有以下缺点:卡箍骨架的材料厚度比较厚,产品在折弯的过程中,由于折弯成型的角度比较大,呈现接近90度的折弯角度,导致产品在折弯的尾端和凹模会出现剐蹭现象,产品表面剐蹭的痕迹,导致表面的R角损坏,导致R角强度减弱,影响产品性能

Benefits of technology

[0016] By separately setting a fixed die plate and a movable die, the punch assembly bends the material during its downward movement, while the movable die flows with the material. This avoids the problem of excessive bending angles seen in clamp frames. The gap at the bending end of the clamp frame is a negative material thickness gap, preventing scraping and the formation of wire marks on the product. Furthermore, because both the material and the die are in dynamic flow, the friction between the die and the product material is reduced, increasing the lifespan of the movable die. Simultaneously, the improved material flow results in fuller, more rounded corners.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-2 This utility model provides a technical solution: a movable rotating mold, comprising:

[0022] Punch assembly, used to apply pressure to the clamp frame for stamping and bending;

[0023] Die fixing plate 7 is located below the punch assembly, and a mounting groove is provided on the die fixing plate 7.

[0024] There are two movable dies 5, which are symmetrically arranged in the mounting groove and are rotatably connected to the mounting groove. The movable dies 5 are used to bend the clamp frame during stamping. The movable dies 5 are composed of a right-angled part 51 and a rounded part 52.

[0025] Before stamping, the clamp frame is positioned using the right-angle portion 51. During stamping, the clamp frame is chamfered using the rounded corner portion 52. By separately setting the die fixing plate 7 and the movable die 5, the punch assembly bends the material during its downward movement. The movable die 5 can flow with the material, preventing problems caused by excessive bending angle of the clamp frame. The gap at the end of the clamp frame bend is a negative material thickness gap, preventing scraping and the formation of wire marks on the product. Furthermore, because both the material and the die are in dynamic flow, the friction between the die and the product material is reduced, increasing the lifespan of the movable die 5. Simultaneously, the better material flow results in a fuller R-angle.

[0026] In this embodiment, the punch assembly is provided with an upper fixing plate 1, an upper pad plate 2, a die shank 3 and a punch module 4 from top to bottom. The upper fixing plate 1 and the upper pad plate 2 are fixedly connected, the upper pad plate 2 and the die shank 3 are fixedly connected, the die shank 3 and the punch module 4 are fixedly connected, and the bottom end of the punch module 4 is rounded.

[0027] In use, the external stamping equipment is connected through the die handle 3, which drives the punch assembly to move downward, and the rounded corner part at the bottom of the punch module 4 is used to stamp and bend the clamp frame.

[0028] In this embodiment, a lower fixing block 6 is also provided on any opposite side wall of the mounting groove, and the lower fixing block 6 is fixedly connected to the mounting groove.

[0029] By setting the lower fixing block 6, the rotation of the movable die 5 is limited, so as to prevent the right angle part 51 of the movable die 5 from rotating excessively.

[0030] In this embodiment, a reset spring 12 is fixedly connected to the top end of the lower fixing block 6, and the other end of the reset spring 12 is fixedly connected to the movable die 5.

[0031] During stamping, the movable die 5 rotates to stretch the return spring 12. After stamping is completed, the return spring 12 retracts and drives the movable die 5 to return to its original position.

[0032] In this embodiment, a forming die 8 is provided in the center of the bottom wall of the mounting groove of the die fixing plate 7. The forming die 8 is used to abut against the bottom of the clamp frame during stamping.

[0033] The clamp frame is stamped by the cooperation of the forming die 8 and the punch assembly.

[0034] In this embodiment, the bottom end of the die fixing plate 7 is connected to the bottom plate 11, and the bottom end of the bottom plate 11 is provided with a material unloading assembly.

[0035] In this embodiment, the unloading assembly includes a punching rod 10 and an elastic reset member arranged from top to bottom. The elastic reset member is fixedly connected to the lower base plate 11 by bolts. The top and bottom ends of the elastic reset member are respectively fixedly provided with clamping plates. The bottom four corners of the forming die 8 are provided with sliding grooves. There are four punching rods 10. One end of the punching rod 10 passes through the lower base plate 11 and corresponds to the sliding groove at the bottom of the forming die 8. The other end of the punching rod 10 is connected to the clamping plate.

[0036] During stamping, the forming die 8 slides down along the punch rod 10 under the pressure of the external stamping equipment, squeezing the clamping plate above the elastic reset part. After stamping, the deformation of the elastic reset part is restored, driving the forming die 8 to reset, and at the same time ejecting the processed clamp.

[0037] In this embodiment, the elastic reset component is the unloading spring 9.

[0038] Working principle: By starting the external stamping equipment, the cam module 4 is driven to move downward to stamp the clamp frame. At the same time, the movable die 5 rotates, which is coordinated with the material movement of the clamp frame. After the stamping is completed, the return spring 12 retracts to drive the movable die 5 to reset, and the unloading spring 9 drives the forming die 8 to reset, thus ejecting the stamped clamp frame.

[0039] 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.
