Detailed Description

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

The first embodiment is as follows:

as shown in fig. 1 to 2, an environment-friendly punching and punching apparatus provided in an embodiment of the present invention includes a punch located at a rear end of a material conveying direction, and further includes:

the base 50 is used for bearing materials, and the materials move on the base 50;

the power mechanism comprises a driving motor 10, a connecting rod 11, a friction driving rod 12, a sliding support 20 and a sliding block 21, wherein one end of the connecting rod 11 is arranged at the output end of the driving motor 10 in a transmission manner, one end of the friction driving rod 12 is hinged to the other end of the connecting rod 11, the other end of the friction driving rod 12 is hinged to the sliding block 21, the sliding block 21 is slidably arranged on the sliding support 20, the sliding direction of the sliding block 21 is parallel to the conveying direction of the materials, and the sliding block 21 is driven to reciprocate when the motor rotates; as shown in fig. 1, the sliding support 20 is provided with a dovetail groove, and the extending direction of the dovetail groove is consistent with the conveying direction of the material.

In operation, the punch punches through the sheet material, and the hole formed after punching is capable of receiving the free end of the drive block 41. When the driving motor 10 rotates, the connecting rod 11 is driven to rotate, the connecting rod 11 drives the friction driving rod 12 to act when rotating, and because one end of the friction driving rod 12 is hinged on the sliding block 21, the friction driving rod 12 can pull and push the sliding block 21, and the sliding block 21 can be in periodic reciprocating motion along the extending direction of the dovetail groove. When the sliding block 21 moves, the rotating shaft 43 is driven to move, the rotating shaft 43 drives the driving block 41 to move while moving, when the driving block 41 moves backwards, due to no blocking, the sliding block can slide on the material, the material is heavier, the driving block 41 cannot drive the material to move backwards enough, when the sliding block 21 moves to the rearmost end, the free end of the driving block 41 is clamped in a hole punched by the material (which can be realized by adjusting the length of the connecting rod 11 and the distance between punched holes of the material), then the sliding block 21 moves in the reverse direction, that is, when the sliding block moves towards the conveying direction of the material, the driving block 41 rotates due to the blocking of the material, but at this moment, the blocking rod 42 prevents the driving block 41 from rotating, at this moment, the driving block 41 can force the material to move, the conveying of the material is completed, and the material.

Example two:

during punching, punching is realized by shearing materials. During shearing, burrs can be formed on the lower end face of the material, extra secondary grinding is needed, the labor amount is increased, and the efficiency is low.

As shown in fig. 3 to 6, the present embodiment further includes an abdicating slide bar 23, a receiving slide sleeve 22 and a deburring device;

the deburring device comprises a friction wheel 30, a first belt pulley 31, a second belt pulley 32, a first bevel gear 33, a second bevel gear 34, a plurality of synchronous wheels 35 and scrapers 36 which correspond to the synchronous wheels 35 one by one; the friction driving rod 12 is matched with the friction wheel 30, when the friction driving rod 12 is contacted with the friction wheel 30, the friction driving rod 12 can drive the friction wheel 30 to rotate by virtue of friction force, the friction wheel 30 is rotatably arranged on the base 50, the first belt pulley 31 is coaxially and fixedly arranged with the friction wheel 30, and the friction wheel 30 drives the first belt pulley 31 to synchronously rotate when rotating; the second belt pulley 32 is rotatably arranged on the base 50, and the first belt pulley 31 and the second belt pulley 32 are arranged through belt transmission; the first bevel gear 33 and the second belt pulley 32 are coaxially and fixedly arranged, the synchronizing wheel 35 is rotatably arranged on the base 50, and the second bevel gear 34 and any one of the synchronizing wheels 35 are coaxially and fixedly arranged; the synchronous wheels 35 extend along the conveying direction of the material, the synchronous wheels 35 are meshed, when any synchronous wheel 35 rotates, other synchronous wheels 35 can be driven to rotate synchronously, the scraper 36 is coaxially and fixedly arranged on the synchronous wheels 35, when the synchronous wheels 35 rotate, the scraper 36 is driven to rotate, and when the scraper 36 rotates, burrs at the bottom of the material can be cleaned; offer a plurality of grooves of stepping down that are used for holding scraper 36 on base 50, when the material removed along base 50, scraper 36 was used for clearing up the burr on the material. As shown in FIG. 6, the upper end of the scraper 36 is flush with the upper end of the abdicating groove, the material moves on the base 50, and the lower end surface of the material is attached to the working surface of the scraper 36, so that the burr can be cleaned when the scraper 36 rotates.

In operation, as shown in fig. 6, the driving motor 10 rotates to drive the friction driving rod 12 to move, the friction driving rod 12 is driven by the connecting rod 11 to move upwards and leftwards, then move downwards and rightwards, and finally move upwards and rightwards (wherein, the upper, lower, left and right sides are described by taking fig. 6 as an example), when the friction driving rod 12 moves downwards and rightwards, the friction driving rod 12 cooperates with the friction wheel 30, when cooperating, the friction driving rod 12 drives the friction wheel 30 to rotate, the friction wheel 30 drives the second belt pulley 32 to rotate through the first belt pulley 31 when rotating, the second belt pulley 32 drives the synchronizing wheel 35 to rotate through the first bevel gear 33 and the second bevel gear 34, and when the synchronizing wheel 35 rotates, the scraper 36 is driven to rotate, so as to clean burrs. Because the intermittent type nature of punching a hole, only after the material punches a hole, just need carry out the burring, scraper 36 also is intermittent type nature rotation and the cadence keeps unanimous with punching a hole in this scheme, avoids scraper 36 continuous rotation to the damage of material and the increase of load.

The cooperation of the friction driving rod 12 and the friction wheel 30 can avoid the problem that the rack and the gear cannot be effectively engaged in the next process to generate 'top teeth' or 'colliding teeth' due to the inertia rotation offset of the gear relative to the gear engagement. Meanwhile, the friction driving mode can form effective overload protection under abnormal working, and equipment overload damage is avoided.

Further, as shown in fig. 7, the sliding device further comprises a spring 24, one end of the spring 24 is fixedly disposed in the accommodating sliding sleeve 22, and the other end of the spring 24 is fixedly connected to the abdicating sliding rod 23. Since the friction driving rod 12 is squeezed with the friction wheel 30 during the downward movement, the abdicating slide rod 23 moves upward to form an abdicating space. However, when the friction driving rod 12 drives the friction wheel 30 to rotate, the friction driving rod 12 is easy to move upwards due to the large load of the friction wheel 30, and the friction force is insufficient due to insufficient pressure, so that the 'slip' is generated. And through the arrangement of the spring 24, pressure can be generated at the end part of the friction driving rod 12 far away from the connecting rod 11, so that the 'slip' caused by the 'upwarp' of the end part of the friction driving rod 12 far away from the connecting rod 11 is avoided.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
