Description

A kind of mechanical equipment for sheet punching and punching

technical field

The invention relates to the field of machining, in particular to a mechanical device for punching and punching a plate.

Background technique

Stamping is a forming and processing method that applies external force to sheets, strips, pipes and profiles by means of presses and dies to cause plastic deformation or separation to obtain workpieces (stampings) of desired shape and size. Stamping processing is a production technology of product parts with a certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the sheet is directly subjected to deformation force in the mold and deformed. Sheet material, mold and equipment are the three elements of stamping processing. According to the stamping temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is performed at room temperature and is a commonly used stamping method for thin sheets. It is one of the main methods of metal plastic working (or pressure working), and also belongs to material forming engineering technology.

In decorative sheet metal processing, it is often necessary to punch holes of various patterns on the sheet as needed to be used as metal decorative components. And this is generally continuous stamping on the plate, and the plate needs to be periodically moved a fixed distance. Due to the small distance, the control of the distance is relatively high. In the prior art, manual feeding is used, and it is difficult to control the distance, and the stamping operation is noisy and dangerous.

Detailed ways

A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

As shown in FIGS. 1 to 6 , a mechanical device for punching and punching a plate 11 provided by an embodiment of the present invention includes:

The support 10 is used to support the plate 11, as shown in FIG. 1, it has a C-shaped structure, including a bottom wall and two side walls, a groove for accommodating the plate 11 is formed between the two side walls, and the plate 11 move within the groove;

The driving wheel 30 is rotatably arranged on the support 10, and a plurality of driving blocks 31 are arranged on the driving wheel 30. In this embodiment, four driving blocks 31 are used as an example. It is set that the driving block 31 is adapted to the punching groove of the plate 11. When the driving wheel 30 rotates, the driving block 31 is gradually inserted into the punching groove, and then when the driving wheel 30 continues to rotate, the driving block 31 toggles the plate 11 and drives the plate 11 to move. , the device is arranged on the rear side of the punch press along the feeding direction, so that the unprocessed area of the sheet 11 enters the processing area of the punch press;

The driving device is used to drive the driving wheel 30 to rotate periodically, and the driving device may specifically be a power device such as a motor and an internal combustion engine.

Specifically, the driving device includes a driving motor 20 , a cam 21 , a swing rod 23 , a connecting rod 24 , a slider 25 , a driving rod 22 and a gear 26 , the driving motor 20 is fixedly arranged on the support 10 , and the cam 21 is drivingly connected to the driving motor At the output end of 20, the middle of the swing rod 23 is hinged to the support 10, one end of the swing rod 23 abuts on the cam 21, the other end is hinged to one end of the connecting rod 24, and the slider 25 is hinged to the other end of the connecting rod 24; One end of the driving rod 22 is hinged to the cam 21, the driving rod 22 is provided with a chute 221, and the sliding block 25 is slidably arranged in the chute 221; , the gear 26 is rotatably arranged on the support 10 , and the gear 26 is coaxially connected to the driving wheel 30 .

During operation, the motor drives the cam 21 to rotate. When the cam 21 rotates, because one end of the swing rod 23 abuts on the cam 21, when the cam 21 rotates to a high point, the side of the swing rod 23 close to the cam 21 is raised, and the other side is raised. Lowering, the swing rod 23 drives the connecting rod 24 to descend. Since the sliding block 25 is hinged on the connecting rod 24, the sliding block 25 will force the driving rod 22 to move down under the driving of the connecting rod 24, so that the rack and gear on the driving rod 22 26 are engaged. In this process, one end of the driving rod 22 is hinged on the cam 21, and the driving rod 22 is eccentrically hinged on the cam 21. When the cam 21 rotates, it will drive the driving rod 22 to move, so the driving rod 22 will drive the gear during this process. 26 rotates, the gear 26 and the driving wheel 30 are coaxially driven and arranged, which will drive the driving wheel 30 to rotate, and the driving wheel 30 will drive the driving block 31 to drive the plate 11 to move. When the drive rod 22 returns, the cam 21 just enters the low point area, the end of the pendulum rod 23 close to the cam 21 descends, and the other end rises, driving the connecting rod 24 to rise, the connecting rod 24 drives the slider 25 to rise, and the slider 25 forces the drive The rod 22 moves upward, so the driving rod 22 is disengaged from the gear 26 in the process of returning. During this process, the gear 26 does not rotate, and the driving wheel 30 also does not rotate. Then go to the next itinerary.

Of course, the above-mentioned gear 26 can also be a friction wheel, and the driving rod 22 is a friction rod, and the friction wheel is driven to rotate by the friction rod.

Further, a runner 232 is also included, and the runner 232 is rotatably disposed at one end of the swing rod 23 , and the runner 232 abuts on the cam 21 . The cam 21 is made of magnetically attractive material, and the runner 232 is made of magnetic material. The moment generated by the suction force between the runner 232 and the cam 21 can overcome the part of the pendulum rod 23, the connecting rod 24, the slider 25 and the The sum of the gravitational force of the driving rod 22 is used as the generated moment, so as to keep the runner 232 and the cam 21 in a state of being in contact with each other all the time.

In other embodiments, a counterweight block 231 is also included. The counterweight block 231 is fixedly arranged on the side of the swing rod 23 close to the cam 21 . The runner 232 is always in contact with the cam 21 . In this embodiment, the preparation materials of the cam 21 and the runner 232 can be flexibly set according to actual needs.

As shown in FIG. 6 , arc-shaped guide surfaces are provided on both sides of the driving block 31 along the moving direction of the plate 11 , so that the driving block 31 can smoothly cut into the punching groove and escape smoothly.

The above disclosures are only a few specific embodiments of the present invention, however, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
