Description

Technical Field

[0001] The utility model belongs to the technical field of fork processing, and in particular relates to a fork bending and flattening device. Background Art

[0002] The fork is a forklift attachment, which is equivalent to a manipulator mounted on a forklift. It is widely used in warehousing, papermaking, packaging, printing, tobacco, home appliances, wine and beverages, wool and cotton textiles, port terminals, railways, automobile manufacturing, steel smelting, chemicals and construction industries. Traditional forks are "L" shaped. In the process of fork production, a bending and flattening device is usually used to process the fork straight blank.

[0003] According to a bending device for fork production with authorization announcement number CN211489146U, it can be known that this patent is a known prior art, and although this patent has the advantages of reducing the difficulty of fixing the upper mold and improving the efficiency of fixing the upper mold, the technical solution of this patent still has the following defects in actual use: when the fork straight blank is bent, the two ends of the fork will be tilted and inclined, and the movement direction of the push plate is vertically upward, that is, the end of the push plate will contact the inclined surface of the fork. Since the contact between the two is point contact (that is, the contact area is small), it is easy for the fork to shake when it is taken out, or even fall, which will cause inconvenience to the subsequent fork removal. For this reason, we proposed a fork bending and flattening device. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] See also Figure 1 and Figure 3 The utility model provides a fork bending and flattening device, including a lower mold 1, a roller is fixedly installed at the bottom of the lower mold 1, and an anti-skid component 2 is arranged at the bottom of the side of the lower mold 1, and the anti-skid component 2 includes a mounting plate 21, the mounting plate 21 is fixedly connected to the bottom of the side of the lower mold 1, and the internal thread of the mounting plate 21 is sleeved with an adjusting rod 22, the bottom end of the adjusting rod 22 is fixedly connected with an anti-skid plate 23, and the bottom of the anti-skid plate 23 is provided with anti-skid patterns;

[0021] In this embodiment, when the fork bending and flattening device is pushed, the roller rolls due to the force, and the lower mold 1 moves, so that the fork bending and flattening device can be moved for use. If the fork bending and flattening device is moved to the working area, the adjusting rod 22 is rotated to rotate and move downward, and the adjusting rod 22 will drive the anti-skid plate 23 to rotate and move downward, so that the bottom of the anti-skid plate 23 is in close contact with the ground, increasing the friction between the two, thereby improving the stability of the fork bending and flattening device.

[0022] See also Figure 1 and Figure 2 A fork bending cavity 3 is provided at the top of the lower mold 1, a support plate 4 is fixedly connected to the top of one side of the lower mold 1, a cross plate 5 is fixedly connected to the top of the support plate 4, an electric hydraulic rod 6 is fixedly sleeved inside the cross plate 5, a fixing plate 7 is fixedly connected to the bottom end of the electric hydraulic rod 6, the bottom end of the electric hydraulic rod 6 and the top of the fixing plate 7 are perpendicular to each other, the fixing plate 7 and the upper mold 8 are fixedly connected by bolts, an upper mold 8 is fixedly installed at the bottom of the fixing plate 7, the upper mold 8 is located directly above the fork bending cavity 3, and the upper mold 8 and the fork bending cavity 3 are adapted to each other;

[0023] In this embodiment, the fork blank is first placed on the top of the lower mold 1, and then the electric hydraulic rod 6 is started to cause an extension movement, and the electric hydraulic rod 6 will drive the upper mold 8 to move vertically downward, so that the bottom of the upper mold 8 is in contact with the top of the fork blank. As the upper mold 8 continues to move downward, the fork blank will gradually bend and enter the interior of the fork bending cavity 3 until the bent fork is tightly fitted with the inner wall of the lower mold 1 and the outside of the upper mold 8, thereby facilitating the bending and flattening of the fork blank.

[0024] See also Figure 2A through opening 9 is provided on the inner side of the lower mold 1, and an electric push rod 10 is fixedly connected to the bottom of the inner cavity of the lower mold 1, and a push plate 11 is fixedly connected to the top of the electric push rod 10. The push plate 11 is located inside the through opening 9, and the push plate 11 is inclined;

[0025] In this embodiment, when the straight fork blank is bent, the electric hydraulic rod 6 is started to retract, and the electric hydraulic rod 6 will drive the upper mold 8 to move vertically upward until the upper mold 8 returns to its original position, and then the electric push rod 10 is started to extend, and the electric push rod 10 will drive the push plate 11 to move vertically upward. Since the push plate 11 in the inclined state can fit closely with the inclined surface of the bent fork, the contact area between the two can be increased, which makes it convenient to use the push plate 11 to smoothly push the bent fork out of the inside of the lower mold 1, thereby bringing convenience to the subsequent removal of the fork.

[0026] The working principle and use process of the utility model are as follows: first, the fork straight blank is placed on the top of the lower mold 1, and then the electric hydraulic rod 6 is started to extend, and the electric hydraulic rod 6 drives the upper mold 8 to move vertically downward, so that the bottom of the upper mold 8 and the top of the fork straight blank are in contact, and as the upper mold 8 continues to move downward, the fork straight blank will gradually bend and enter the interior of the fork bending cavity 3, so as to facilitate the bending and flattening of the fork straight blank;

[0027] Then, when the bent fork is tightly fitted with the inner wall of the lower mold 1 and the outer part of the upper mold 8, it means that the fork straight blank has been bent. At this time, the electric hydraulic rod 6 is started to retract, and the electric hydraulic rod 6 drives the upper mold 8 to move vertically upward until the upper mold 8 returns to its original position.

[0028] Finally, the electric push rod 10 is started to extend, and the electric push rod 10 drives the push plate 11 to move vertically upward. Since the push plate 11 in the inclined state can fit closely with the inclined surface of the bent fork, the contact area between the two can be increased, making it convenient to use the push plate 11 to smoothly push the bent fork out of the lower mold 1, thereby facilitating the subsequent removal of the fork.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
