Environment-friendly punching and drilling equipment

[0024] Example one:

[0025] Such as Figure 1 to Figure 2 As shown, an environmentally-friendly punching and punching device provided by an embodiment of the present invention includes a punching machine, which is located at the rear end of the material conveying direction, and further includes:

[0026] The base 50 is used to carry materials, and the materials move on the base 50;

[0027] The power mechanism includes a drive motor 10, a connecting rod 11, a friction drive rod 12, a sliding bracket 20, and a sliding block 21. One end of the connecting rod 11 is driven and arranged at the output end of the drive motor 10, and one end of the friction drive rod 12 is hinged to the connection The other end of the rod 11 and the other end of the friction drive rod 12 are hinged to the slider 21. The slider 21 is slidably arranged on the sliding bracket 20 and the sliding direction of the slider 21 is parallel to the conveying direction of the material. When the motor rotates , Drives the slider 21 to move back and forth; such as figure 1 As shown, the sliding support 20 is provided with a dovetail groove, and the extension direction of the dovetail groove is consistent with the conveying direction of the material.

[0028] Drive device, such as figure 1 with figure 2 As shown, it includes a rotating shaft 43, a driving block 41 and a gear lever 42, one end of the rotating shaft 43 is fixedly arranged on the slider 21, the driving block 41 is rotatably arranged on the rotating shaft 43, and the driving block 41 can rotate along the axis of the rotating shaft 43 One end of the gear lever 42 is fixedly connected to the slider 21, and the drive block 41 is located on one side of the gear lever 42 along the material advancing direction. The gear lever 42 is used to block the drive block 41 from moving in a direction away from the material conveying.

[0029] During operation, the punch punches the plate, and the hole formed after the punch can accommodate the free end of the driving block 41. When the driving motor 10 rotates, it drives the connecting rod 11 to rotate. When the connecting rod 11 rotates, it drives the friction drive rod 12 to move. Since one end of the friction drive rod 12 is hinged on the slider 21, the friction drive rod 12 will pull and push the slider 21. The slider 21 will periodically reciprocate along the extending direction of the dovetail groove. When the sliding block 21 moves, it will drive the shaft 43 to move. The shaft 43 moves while driving the drive block 41 to move. When the drive block 41 moves backward, it will slide on the material because it is not blocked. The material is heavy and the drive block 41 is not enough to drive The material moves backward. When the slider 21 moves to the rearmost end, the free end of the drive block 41 is stuck in the hole punched by the material (this can be achieved by adjusting the length of the connecting rod 11 and the spacing of the material punching), and then slides When the block 21 moves in the reverse direction, that is, when it moves toward the conveying direction of the material, the driving block 41 will rotate due to the blocking of the material at this time, but at this time the gear lever 42 prevents the driving block 41 from rotating, and the driving block 41 will now Force the material to move and complete the transportation of the material. The material under the punch die moves exactly one punching distance.

[0030] Embodiment two:

[0031] Because when punching, punching is realized by cutting the material. When cutting, burrs will be formed on the lower end surface of the material, which requires additional secondary grinding, resulting in increased labor and low efficiency.

[0032] Such as Figure 3 to Figure 6 As shown, therefore, this embodiment also includes a retreating sliding rod 23, a receiving sliding sleeve 22 and a deburring device;

[0033] The receiving sliding sleeve 22 is fixedly arranged on the sliding block 21, and the giving way sliding rod 23 is slidably arranged in the receiving sliding sleeve 22; the end of the friction drive rod 12 away from the connecting rod 11 is hinged to the giving way sliding rod 23, and the giving way sliding When the rod 23 moves up and down, a space is formed for the friction drive rod 12;

[0034] The deburring device includes a friction wheel 30, a first belt wheel 31, a second belt wheel 32, a first bevel gear 33, a second bevel gear 34, a number of synchronous wheels 35 and a scraper 36 corresponding to the synchronous wheel 35 one-to-one; a friction drive rod 12 Cooperating with the friction wheel 30, when the friction drive rod 12 is in contact with the friction wheel 30, the friction drive rod 12 can drive the friction wheel 30 to rotate by virtue of friction. The friction wheel 30 is rotatably arranged on the base 50, and the first pulley 31 Coaxially fixed with the friction wheel 30, the friction wheel 30 drives the first pulley 31 to rotate synchronously when the friction wheel 30 rotates; the second pulley 32 is rotatably arranged on the base 50, and the first pulley 31 and the second pulley 32 are set through belt transmission; A bevel gear 33 and the second belt pulley 32 are fixed coaxially, the synchronization wheel 35 is rotatably disposed on the base 50, and the second bevel gear 34 is fixed coaxially with any synchronization wheel 35; several synchronization wheels 35 are conveyed along the material The synchronizing wheel 35 is arranged in an extended direction. When any synchronizing wheel 35 rotates, it will drive the other synchronizing wheels 35 to rotate synchronously. The scraper 36 is coaxially fixed on the synchronizing wheel 35. When the synchronizing wheel 35 rotates, the scraper 36 is driven When the scraper 36 rotates, the burr on the bottom of the material will be cleaned; the base 50 is provided with a number of relief slots for accommodating the scraper 36. When the material moves along the base 50, the scraper 36 is used to clean the burr on the material. Such as Image 6 As shown, the upper end of the scraper 36 is flush with the upper end of the relief groove, the material moves on the base 50, and the lower end of the material fits the working surface of the scraper 36, so that the scraper 36 can clean the burrs when it rotates.

[0035] When working, such as Image 6 As shown, the rotation of the drive motor 10 will drive the friction drive rod 12 to move. Driven by the connecting rod 11, the friction drive rod 12 will move up and to the left, then move down to the left, and then down to the right. Move, and finally move up to right (where up, down, left, and right are facing Image 6 As an example description), when the friction drive rod 12 moves downward and rightward and upward and rightward, the friction drive rod 12 will cooperate with the friction wheel 30. When the friction drive rod 12 is engaged, the friction wheel 30 will be driven to rotate. When the friction wheel 30 rotates, the first pulley 31 drives the second pulley 32 to rotate. The second pulley 32 drives the synchronous wheel 35 to rotate through the first bevel gear 33 and the second bevel gear 34. When the synchronous wheel 35 rotates, it drives the scraper 36 to rotate. The cleaning of burrs. Due to the intermittent punching, deburring is only required after the material is punched. In this solution, the scraper 36 also rotates intermittently and the pace is consistent with the punching, so as to avoid the continuous rotation of the scraper 36 to damage the material and Increase in load.

[0036] The cooperation of the friction drive rod 12 and the friction wheel 30, relative to the gear meshing, can prevent the gear from shifting due to inertial rotation, so that the rack and gear cannot mesh effectively in the next process, resulting in the problem of "top teeth" or "tooth collision" . At the same time, the friction drive method can also form an effective overload protection under abnormal operation to avoid equipment overload damage.

[0037] Further, as Figure 7 As shown, a spring 24 is also included. One end of the spring 24 is fixedly arranged in the receiving sliding sleeve 22 and the other end is fixedly connected to the retreating sliding rod 23. As the friction drive rod 12 moves downwards, it will form a squeeze with the friction wheel 30. At this time, the yield sliding rod 23 moves upward to form a yield space. However, when the friction drive rod 12 drives the friction wheel 30 to rotate, it is easy to cause the friction drive rod 12 to move upward due to the heavy load of the friction wheel 30. Due to insufficient pressure, the friction force is insufficient and "skidding" occurs. With the arrangement of the spring 24, pressure can be generated at the end of the friction drive rod 12 away from the connecting rod 11, so as to avoid the "slip" caused by the end of the friction drive rod 12 away from the connecting rod 11.
