Generally, a mechanical cutting device is required when grooving the top of a hardware plate.

[0003] The existing mechanical cutting devices for hardware processing have the following disadvantages during use:

[0004] Generally, a single fixture table for clamping hardware plate components is set on the cutting device, and manual operation is required to fix the hardware plate components through the set clamping structure. After the hardware plate components are clamped and fixed, the hardware plate components are manually controlled to approach the cutting device, or the cutting device is manually controlled to approach the hardware plate components to achieve the purpose of cutting and grooving. However, in such a cutting method, the clamping operation requires manual intervention, resulting in very low cutting efficiency and unable to double the cutting efficiency. Therefore, a mechanical cutting device for hardware processing is needed. Content of the Utility Model

[0023] Embodiment

[0024] Generally, a single fixture table for clamping hardware plate components is set on the cutting device, and manual operation is required to fix the hardware plate components through the set clamping structure. After the hardware plate components are clamped and fixed, the hardware plate components are manually controlled to approach the cutting device, or the cutting device is manually controlled to approach the hardware plate components to achieve the purpose of cutting and grooving. However, in such a cutting method, the clamping operation requires manual intervention, resulting in very low cutting efficiency and unable to double the cutting efficiency.

[0025] Therefore, please refer to Figures 1-3 , the present utility model provides a mechanical cutting device for hardware processing, including: a cutting table 1, a motor a 2 is fixedly connected to the middle of the bottom end of the cutting table 1, the output shaft of the motor a 2 penetrates the cutting table 1 and is fixedly connected with a cutting knife 21. Two symmetrically arranged horizontal sliding grooves are opened at the top of the cutting table 1. A sliding seat 41 with a cross-section in an I-shaped structure is respectively slidably connected in the two horizontal sliding grooves. The two sliding seats 41 are in a left-right state, and an L-shaped workpiece seat 3 is fixedly connected to the top end of each of the two sliding seats 41.

[0026] It further includes a bidirectional synchronous driving structure 4 and a linkage type double synchronous clamping and loosening structure 5. The bidirectional synchronous driving structure 4 is installed on the cutting table 1 and is connected to the two sliding seats 41.

[0027] The linkage type double synchronous clamping and loosening structure 5 is installed on the cutting table 1 and is connected to the two L-shaped workpiece seats 3.

[0028] Further as Figures 1-3 shown, specifically, in order to enable the two L-shaped workpiece seats 3 to achieve synchronous movement in opposite directions, the bidirectional synchronous driving structure 4 is set to include screws 42 threadedly connected to the two sliding seats 41. Both ends of the two screws 42 are rotatably connected to the corresponding sliding grooves. The thread directions of the two screws 42 are opposite. The same ends of the two screws 42 extend to the outside of the cutting table 1 and are fixedly connected with chain wheels 43. A chain 44 is drivingly connected between the two chain wheels 43. One end of one of the screws 42 away from the chain wheel 43 extends to the outside of the cutting table 1 and is connected to the output shaft of a motor b 45. The motor b 45 is fixedly connected to the outside of the cutting table 1.

[0029] Further as Figures 1-3As shown, it is worth specifically explaining that in order to actively clamp and fix the hardware plate components on the two L-shaped workpiece seats 3 during the operation of the above-mentioned bidirectional synchronous drive structure 4 without manual operation interference, a linkage double synchronous clamping and loosening structure 5 is provided, including convex grooves opened at the centers of the tops of the two L-shaped workpiece seats 3. A transmission block 51 with a convex cross-section slides in each of the two convex grooves. Symmetrically arranged push-pull rods 54 are hinged to the tops of the two transmission blocks 51. The other ends of the two push-pull rods 54 are hinged to the top of the Z-shaped clamping block 55. Sliding portions with a convex cross-section are provided at the bottoms of the Z-shaped clamping blocks 55, and the sliding portions are slidably connected to the sliding grooves provided on the L-shaped workpiece seats 3. Transmission columns 52 are fixedly connected to the ends of the two transmission blocks 51 facing away from the middle of the cutting table 1. The bottoms of the transmission columns 52 are movably inserted into the transmission channels 53. The two transmission channels 53 are symmetrically opened on the cutting table 1. The middle cross-section of the transmission channel 53 is in a V-shaped structure, and the two ends of the transmission channel 53 are horizontally arranged.

[0030] The middle of the transmission channel 53 is in a sunken horizontal structure, which is the key to causing the two Z-shaped clamping blocks 55 to move actively towards each other. The diameter of the transmission column 52 is equal to the width of the transmission channel 53 to prevent the transmission column 52 from moving inside it.

[0031] In summary: When using this mechanical cutting device for hardware processing, first place the two hardware plate components on the corresponding L-shaped workpiece seats 3 respectively. By starting the motor b45, the motor b45 drives the screw 42 to rotate. With the transmission setting of the sprocket 43 and the chain 44, the two screws 42 rotate simultaneously. However, the thread directions of the two screws 42 are opposite, so that the two L-shaped workpiece seats 3 move in opposite directions. At this time, the two transmission columns 52 will move in the transmission channels 53. Due to the shape design of the transmission channels 53, the transmission rods will drive the transmission blocks 51 to move away from the middle of the cutting table 1. With the setting of the two push-pull rods 54, the two Z-shaped clamping blocks 55 move towards each other and actively clamp and fix the placed hardware plate components. During the movement, the clamping state is still maintained. Finally, the two Z-shaped clamping blocks 55 move away from each other to actively release the hardware plate components after cutting and grooving, thus achieving the purpose of automatically clamping, fixing and cutting the hardware plate components without manual interference, greatly improving the cutting efficiency and doubling the cutting efficiency.
