Description

Technical Field

[0001] The invention relates to the field of mechanical equipment parts processing, in particular to an anti-scratch punching machine for mechanical equipment parts processing. Background Art

[0002] The stamping process in mechanical processing has many significant advantages, which have made it widely used in industrial production. The following are the main benefits of stamping processing: High production efficiency: The production efficiency of stamping processing is very high because it relies on stamping dies and stamping equipment to complete the processing. The number of strokes of ordinary presses is dozens of times per minute, while high-speed presses can reach hundreds or even thousands of times per minute. Easy to operate, easy to mechanize and automate: Since stamping processing relies on dies and equipment, the operation is relatively simple, and it is easy to mechanize and automate, which is particularly suitable for batch mass production. Stable quality and good interchangeability: The size and shape accuracy of stamping parts are guaranteed by the mold, so their quality is stable, interchangeability is good, and they have the characteristics of "exactly the same". Stamping processing can greatly reduce production costs, especially in mass production, because the long life of the mold further reduces production costs. Complex shapes can be processed: Stamping can process workpieces with reinforcing ribs, ribs, undulations or flanging that are difficult to manufacture by other methods to improve their rigidity. Good surface quality: Due to the effect of the mold, the surface quality of stamping parts is usually good, and generally does not damage the surface quality of the material. Applicable to a variety of materials: Stamping is not only suitable for metal materials, but also for non-metallic materials, with a wide range of applications. Stamping is a form of energy-saving and emission-reducing processing that does not require other heating equipment and is a green and environmentally friendly production method. Stamping processing has significant advantages in improving production efficiency, reducing costs, ensuring product quality, saving materials and energy, and is an indispensable and important process in modern industrial production.

[0013] The present invention provides a scratch-proof punching machine for machining mechanical equipment parts. It has the following beneficial effects: 1) The anti-scratch punching machine for processing spare parts of the mechanical equipment is equipped with a feeding device. When in use, the operator places the mechanical parts in the plug-in board in advance, and then the operator starts the drive motor, which drives the incomplete gear to rotate. Since the incomplete gear is intermittently engaged with the teeth on both sides of the inner wall of the movable frame, the movable frame will intermittently move left and right. The movement of the movable frame drives the moving block to slide on the moving track, thereby driving the mechanical parts of the plug-in board to move to the stamping position, realizing automatic loading and expanding the distance between the staff and the stamping device.

[0014] 2) The anti-scratch punching machine for processing spare parts of mechanical equipment sets a buffer mechanism to place the workpiece to be processed on the inverted U-shaped lower template. The cylinder generates telescopic movement to push the gear below. The side rack and the rack slide under the meshing of the gear, causing the lifting plate to press the pressure plate downward to punch the workpiece below. After the workpiece is under pressure, the inverted U-shaped lower template is also under pressure, and the inverted U-shaped lower template presses the two support plates below. After the support plate is under pressure, it presses the driving arm, causing the limiting wheel at the bottom of the driving arm to push the side push plate outward, and the push plate presses the side compression spring.

[0015] 3) The anti-scratch punching machine for processing spare parts of the mechanical equipment has a connectable battery installed on the machine through a clamping mechanism, and a motor is driven by an external control or battery, and the motor drives the threaded rod to rotate. Among them, since the internal threaded barrel is sleeved on the threaded rod, and the bottom of the force plate is just embedded in the lock groove to limit the internal threaded barrel, when the threaded rod rotates, the internal threaded barrel sleeved on it will move forward. When the side of the internal threaded barrel moves to the side of the inverted U-shaped lower template and presses against the side of the inverted U-shaped lower template, the motor is stopped, and the side end of the force plate also presses against the side of the inverted U-shaped lower template, and the clamping block just clamps the workpiece placed on the inverted U-shaped lower template firmly, thereby leaving a gap between the support seat and the inverted U-shaped lower template, so that the force generated by the workpiece during the processing will be disconnected, and the force transmitted to the inverted U-shaped lower template will go downward, ensuring the stability of the workpiece above.

[0016] 4) The anti-scratch punching machine for processing spare parts of mechanical equipment is equipped with a punching mechanism and a feeding mechanism. After the workpiece is clamped, as the punching is performed, the bottom of the inverted U-shaped lower template is pressed against the fixed column after being subjected to pressure. The fixed column has a buffering effect under the action of the elastic plate and the supporting spring below. After the punching is completed, the mechanical parts fall into the feeding frame under the action of gravity, and fall into the receiving box through the feeding plate for easy storage.

[0029] When in use, the operator places the mechanical parts in the plug board 113 in advance, and then the operator starts the driving motor 54, which drives the incomplete gear 133 to rotate. Since the incomplete gear 133 is intermittently meshed with the teeth 132 on both sides of the inner wall of the movable frame 131, the movable frame 131 will intermittently move left and right. The movement of the movable frame 131 drives the moving block 111 to slide on the moving track 112, thereby driving the mechanical parts of the plug board 113 to move to the stamping position, realizing automatic loading, expanding the distance between the staff and the stamping device, and The workpiece to be processed is placed on the inverted U-shaped lower template 4, and the cylinder generates telescopic movement, pushing the gear below.

At the same time, a connectable battery is installed on the machine, and the motor 54 is driven by an external control or battery, and the motor drives the threaded rod 55 to rotate. Among them, since the internal threaded tube is sleeved on the threaded rod 55, and the bottom of the force distribution plate is just embedded in the lock groove to limit the internal threaded tube, when the threaded rod 55 rotates, the internal threaded tube sleeved on it will move forward. When the side of the internal threaded tube moves to the side of the inverted U-shaped lower template 4 and presses against the side of the inverted U-shaped lower template 4, the motor is stopped, and the side end of the force distribution plate also presses against the side of the inverted U-shaped lower template 4, and the clamping block just clamps the workpiece placed on the inverted U-shaped lower template 4 firmly, thereby leaving a gap between the support seat 53 and the inverted U-shaped lower template 4, so that the force generated by the workpiece during the processing will be disconnected, and the force transmitted to the inverted U-shaped lower template 4 will be downward, thereby ensuring the stability of the workpiece above. At the same time, when the workpiece is clamped, as the punching is performed, the bottom of the inverted U-shaped lower template 4 will be pressed against the fixed column 51 after being subjected to pressure. The fixed column 51 has a buffering effect under the action of the elastic plate 97 and the support spring 93 below. After the punching is completed, the mechanical parts fall into the blanking frame 124 under the action of gravity, and fall into the receiving box 125 through the blanking plate 121 for convenient storage.
