Description

Technical Field

[0001] The present invention relates to the technical field of bending and punching equipment, in particular to a bending, forming and punching device for processing beryllium copper shrapnel. Background Art

[0002] Beryllium copper is a specially treated, high-strength, corrosion-resistant alloy composed primarily of copper, beryllium, aluminum, and manganese. Beryllium copper shrapnel, a shielding cover made of this alloy, possesses numerous excellent properties and is widely used. Stamping dies are a common process equipment used in metalworking. They apply external forces to metal sheets, causing them to plastically deform or separate, thereby creating parts of desired shapes and sizes. Bending stamping dies apply external forces to beryllium copper sheets, causing them to plastically deform, achieving the desired bent shape and size. The die design must take into account the characteristics of beryllium copper and its processing requirements to ensure the precision and quality of the finished product. During processing, the die's punch presses the beryllium copper sheet, bending it along a predetermined trajectory. Simultaneously, die components such as guide pins and sleeves ensure a precise fit between the punch and die, ensuring stability and accuracy during the process.

[0003] The prior art also has the following defects during use: When the bending and forming stamping dies in the prior art are being processed, due to the influence of the workshop environment, a lot of dust and fine particles will inevitably appear on the bending processing platform. In the process of bending and stamping the beryllium copper shrapnel, the product is easily damaged, resulting in a certain degree of production loss. In addition, during the process of transporting the beryllium copper shrapnel for bending and stamping, if the position of the beryllium copper shrapnel cannot be effectively fixed, it is easy to cause errors in the processing of the beryllium copper shrapnel, which will also cause damage to the product to a large extent, and will have an overall adverse impact on the work cost and work efficiency.

[0017] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments. Example

[0018] like Figures 1-6 As shown, a bending forming and punching device for processing beryllium copper shrapnel proposed by the present invention comprises a working platform 1, on which a bending platform 13 and a movable protective cover 4 are provided, and a placement track 5 is provided at the front and rear ends of the working platform 1, a dual-axis control motor 14 is installed at the rear of the working platform 1, and both ends of the dual-axis control motor 14 are connected to a push cover assembly, which is fixed at the lower end of the movable protective cover 4, a sliding track 23 is provided inside the working platform 1, and the bending platform 13 is slidably installed on the sliding track 23, and a lifting mechanism is connected between the bending platform 13 and the movable protective cover 4, and connecting blocks 27 are connected at both ends of the movable protective cover 4, and a first moving tooth 26 is installed on the connecting block 27, and the first moving tooth 26 is meshedly connected to a control gear 29, and the control gear 29 is meshedly connected to a second moving tooth 25, and an auxiliary clamping rod 24 is connected between the second moving teeth 25 on one side; The dual-axis control motor 14 can control the mobile protective cover 4 to move toward both sides. When the mobile protective cover 4 moves, due to the connection relationship between the mobile protective cover 4 and the bending platform 13, the mobile protective cover 4 will drive the bending platform 13 to move upward along the sliding track 23 to the bending processing platform during the movement, and the mobile protective cover 4 will drive the movement of two sets of moving teeth during the movement, so that in the process of opening both sides of the mobile protective cover 4, the auxiliary clamping rod 24 moves toward the middle, and can pass through the side slots of the placement track 5, and cooperate with the placement track 5 to position and clamp the beryllium copper shrapnel in the placement track 5, so that it can maintain a stable conveying state during the subsequent transportation and bending process, and no conveying deviation will occur.

[0019] The dual-axis control motor 14 controls the push cover assembly to drive the movable protective cover 4 to open to both sides so that the bending platform 13 can be moved to the bending processing position, and the movable protective cover 4 simultaneously drives the auxiliary clamping rod 24 to move close to the placement rail 5, thereby clamping and positioning the beryllium copper shrapnel in the placement rail 5.

[0020] Furthermore, a bending and fixing block 12 is provided on the bending platform 13, and a positioning and stabilizing groove 11 is provided on the outer side of the bending and fixing block 12. A positioning and stabilizing block 28 is provided in the middle of the auxiliary clamping rod 24 in the direction toward the bending platform 13, and the positioning and stabilizing block 28 is fitted and connected with the positioning and stabilizing groove 11; During the inward movement of the auxiliary clamping rod 24, the bending platform 13 will also rise synchronously. The positioning and stabilizing block 28 driven by the auxiliary clamping rod 24 can achieve a certain degree of engagement with the bending platform 13 during the movement. Because the bending platform 13 rises through the lifting mechanism, the platform may not be very stable during the bending process. The interlocking cooperation of the positioning and stabilizing block 28 and the positioning and stabilizing groove 11 can further improve the reinforcement of the bending platform 13, thereby realizing the bending processing of the beryllium copper spring.

[0021] When the auxiliary clamping rod 24 drives the positioning and stabilizing block 28 to move toward the bending platform 13 , the positioning and stabilizing block 28 will be engaged and connected with the positioning and stabilizing groove 11 on the bending platform 13 , thereby reinforcing the bending platform 13 .

[0023] The dual-axis motor is installed at the rear of the working platform 1 and does not interfere with the lifting mechanism. The dual-axis control motor 14 controls the rotation of the screw rod 15, so that the mounting block 17 starts to move. During the movement of the mounting block 17, the connecting rod 16 drives the mobile protective cover 4 to open and close.

[0024] Furthermore, the lifting mechanism includes a connecting shaft 18, a moving shaft 21, a second connecting rod 20 and a rotating connecting part 22. The connecting shaft 18 is fixed on both sides of the bottom of the bending platform 13. The moving shaft 21 is installed at the lower end of the connecting shaft 18. The moving shaft 21 and the movable protective cover 4 are connected by the second connecting rod 20. The rotating connecting part 22 is connected to the inner side of the moving shaft 21.

[0025] The second connecting rod 20, the moving shaft 21 and the rotating connecting part 22 are all relatively fixed, and the connecting shaft 18 and the moving shaft 21 are connected by a rotating shaft. When the protective cover 4 moves toward both sides, the second connecting rod 20 is used to synchronously drive the movement of the moving shaft 21 and the rotating connecting part 22, thereby driving the movement of the connecting shaft 18, thereby controlling the bending platform 13 to make it rise along the sliding track 23.

[0026] Furthermore, the rotating connection part 22 is a fan-shaped part, and the inner side of the fan-shaped part is provided with equidistant teeth, and the two groups of rotating connection parts 22 are connected by tooth meshing.

[0027] The rotating connection parts 22 are connected to each other through tooth engagement, which can better stabilize the movement of the lifting mechanism.

[0028] Furthermore, a first connecting rod 19 is provided near the second connecting rod 20 , one end of the first connecting rod 19 is connected to the bottom of the movable protective cover 4 , and the other end of the first connecting rod 19 is installed inside the working platform 1 .

[0030] Furthermore, a top mounting frame 2 is installed at the upper end of the working platform 1 , and a bottom mounting frame 3 is provided at the lower end of the working platform 1 .

[0031] The top mounting frame 2 and the bottom mounting frame 3 can well constitute the equipment frame of the entire working platform 1.

[0032] Furthermore, the bending and forming assembly 8 is fixed at the upper end of the top mounting frame 2.
