Detailed implementation manners

[0024] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present utility model in conjunction with the drawings in the specification. Embodiment 1

[0025] Referring to Figures 1 - 3 , which is the first embodiment of the present utility model, a plastic product forming and punching device is provided. This plastic product forming and punching device includes a placing table 1. On both sides of the inner cavity of the placing table 1, there is a conveyor belt 2. At the top edge of the placing table 1, there is a U-shaped frame 3. At the bottom of the U-shaped frame 3, there is a punching unit 4. On both sides of the U-shaped frame 3, there are two groups of clamping units 5. On one side of the clamping unit 5, there is a fixed unit 6; on one side of the rotating handle 61, there is a cylinder, and the output end of the cylinder is fixedly connected to one end of the driving cavity 51, so that the clamping unit 5 can move back and forth.

[0026] The clamping unit 5 includes a driving cavity 51. An electric push rod 52 is arranged in the inner cavity of the driving cavity 51. One end of the electric push rod 52 is provided with a triangular plate. Two groups of rotating rods 53 are rotatably connected to the surface of the triangular plate. A semi-gear 54 is arranged on one side of the rotating rod 53. A gripper 56 is arranged inside the driving cavity 51, and the semi-gear 54 meshes with the gripper 56.

[0027] Fixed rods 55 are fixedly connected to two sides of the inner cavity of the driving cavity 51 close to each other. The semi-gear 54 is sleeved on the surface of the fixed rod 55. A sliding groove 57 is formed in the inner cavity of the driving cavity 51. A sliding block is arranged on one side of the gripper 56. Multiple groups of saw teeth are arranged at the bottom of the gripper 56 to increase the friction between the plastic product and the gripper 56, so as to clamp more firmly. The gripper 56 is slidably connected to the sliding groove 57 through the sliding block.

[0028] The fixing unit 6 includes a rotating handle 61 fixedly connected to the driving cavity 51. Two groups of fixing columns 62 are arranged on one side of the U-shaped frame 3. A fixing clamp 63 is arranged on the surface of the fixing column 62. Springs 64 are arranged on two sides of the two groups of fixing clamps 63 close to each other.

[0029] During the use process, place the plastic product to be drilled above the conveyor belt 2. When the plastic product moves below the U-shaped frame 3, start the electric push rod 52 to drive the triangular plate on one side of the electric push rod 52 to move, thereby driving the rotating rod 53 to rotate. Since one side of the rotating rod 53 is connected to the semi-gear 54, the semi-gear 54 is driven to rotate. Since the sliding groove 57 meshes with the gripper 56, the sliding block on one side of the gripper 56 is driven to slide inside the sliding groove 57, so that the two grippers 56 approach or move away from each other, thereby clamping the plastic product.

[0030] When the clamping of the plastic product is completed and the drilling device finishes drilling the position to be drilled at the top, pinch the two groups of fixing clamps 63 with the thumb and index finger respectively. Due to the elastic action of the spring 64, the two groups of fixing clamps 63 approach each other, and one end of the fixing clamp 63 leaves the surface of the rotating handle 61. Rotate the rotating handle 61 to drive the plastic product to rotate, align the other surface to be drilled with the drilling unit 4, release the fixing clamp 63, and fix the rotation angle of the rotating handle 61. Embodiment 2

[0031] Refer to Figures 1 - 5 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the drilling unit 4 includes a fixed disk 41. A plurality of folding plates 42 are rotatably connected in a circumferential array on the surface of the fixed disk 41. A hole position is formed on one side of the top of the folding plate 42, and a drill bit connector 43 is arranged on the top of the folding plate 42. The drilling unit 4 includes a column body, and the fixed disk 41 is coaxially arranged with the column body. A plurality of hole positions are arranged on the top of the fixed disk 41.

[0032] The drill bit connector 43 is a key component that connects the drill bit cutting edge to the orifice of the drilling equipment converter, used to achieve a tight connection and gapless engagement between the drill bit and the drilling equipment, giving full play to the processing efficiency and precision of the drill bit, avoiding the degradation and damage of the drilling equipment, and improving the efficiency and quality of drilling operations.

[0033] During use, connect the cylinder on the punching unit 4 to the main body of the drilling rig, connect multiple drill bits to the folding plate 42 through the drill bit connector 43. When in need of use, select the required drill bit, fold the folding plate 42 to align the hole positions on the surface of the folding plate 42 with the hole positions on the surface of the fixed disk 41, fix it with the insertion sheath, and perform punching operations on plastic products. When it is necessary to replace different drill bits, pull out the insertion sheath, fold other folding plates 42, and perform punching operations.

[0034] The remaining structure is the same as that of Embodiment 1.
