[0002] The liner is used to protect the cylinder from direct impact and friction between the grinding body and the material. At the same time, different forms of liners can also be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material. There are many process steps in the processing of the liner, among which bending is an important step.

[0003] When existing bending equipment bends liner plates, workers often place the liner plates into the bending die cavity and use stamping to bend the liner plates, and then take them out manually. Due to cost constraints, the punch heads used for stamping have a long service life and lack regular maintenance. Structural and functional damage to the punch heads can easily affect subsequent bending work. For this reason, we have designed a bending device for producing composite wear-resistant liners to solve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1

[0022] Reference Figure 1-3 , a bending device for producing composite wear-resistant linings, comprising a workbench 1, a supporting plate 7, a workpiece 3 to be bent and a punching head 14, a placing table 2 is fixedly connected to the workbench 1, and two reset assemblies are symmetrically provided in the placing table 2, and the workpiece 3 to be bent is placed on the two reset assemblies, wherein the reset assembly is convenient for pushing the workpiece 3 to be bent out of the placing table 2 after processing is completed, thereby facilitating the removal of the workpiece 3 to be bent, a cylinder 8 is installed at the bottom of the supporting plate 7, and the telescopic end of the cylinder 8 is fixedly connected to the U-shaped plate 11, and a driving assembly is provided in the U-shaped plate 11. Grooves 15 are provided on the side walls of both ends of the punching head 14, and the inner side walls of both ends of the U-shaped plate 11 are provided with pressing assemblies, which extend into the two grooves 15 to fix the punching head 14, and a driving assembly engaged with the two pressing assemblies is installed on the inner rear side wall of the U-shaped plate 11. The driving assembly drives the two pressing assemblies, and then the punching head 14 is disassembled and replaced.

[0023] Here’s how it works:

[0024] In the natural state, the support column is against the ground, which can ensure the stability of the workbench 1 and the support plate 7;

[0025] When performing bending work, the punch head 14 is placed between the two moving blocks 13 and is abutted against the inner rear side wall of the U-shaped plate 11 and the upper end is abutted against the bottom of the two abutting blocks 17;

[0026] Start the motor 9, which drives the second bevel gear 18 to rotate. Under the meshing action, the two first bevel gears 10 drive the threaded rods 12 on both sides to rotate together. Under the meshing action of the threaded rods 12, the two moving blocks 13 can be moved closer to each other and the two fixed blocks 16 can be extended into the two grooves 15 respectively to clamp and fix the punch head 14, thereby completing the installation of the punch head 14.

[0027] Similarly, performing the above operation in reverse can facilitate the removal of the punch head 14, and thus facilitate the replacement of the punch head 14, and can meet different bending requirements of the bend part 3 by using different punch heads 14;

[0028] Place the workpiece 3 to be bent on the two reset blocks 4, then start the cylinder 8. Through the expansion and contraction of the cylinder 8, the U-shaped plate 11 is driven downward, and then the workpiece 3 to be bent is bent by the punch head 14.

[0029] After the part to be bent 3 is subjected to the impact force, the reset block 4 at the bottom is first driven to move downward, so that the two sides of the part to be bent 3 enter the interior along the two sides of the placement table 2, which plays a limiting role for the part to be bent 3, facilitates the bending work, and avoids its displacement during the bending process. The punching head 14 continues to move downward to bend the part to be bent 3. After the bending is completed, the cylinder 8 drives the U-shaped plate 11 to move upward and reset, and then the spring 6 can push the reset block 4 to move upward, making it easier for 3 to take out the part to be bent from the placement table 2.

[0030] Example 2

[0031] Based on embodiment one, the placement table 2 is U-shaped, and its upper end is tilted so that its upper end gradually narrows toward its internal opening, that is, the placement table 2 is tilted to facilitate the positioning of the part to be bent 3 entering the placement table 2, thereby avoiding shaking during the bending process and ensuring the normal progress of the bending work.

[0032] Example 3

[0033] Based on Example 1, the reset assembly includes a telescopic rod 5 fixedly connected to the placement table 2, the telescopic end of the telescopic rod 5 is fixedly connected to a reset block 4, the part to be bent 3 is placed on the reset block 4, and a plurality of springs 6 are connected between the reset block 4 and the inner bottom of the placement table 2. The spring 6 is a tension spring, which can push the reset block 4 to move upward after the bending work is completed, so that the part to be bent 3 is moved to the outside of the placement table 2, thereby facilitating the removal of the part to be bent 3.

[0034] Example 4

[0035] Based on embodiment one, the pressing assembly includes a threaded rod 12 rotatably connected to the inner wall of the U-shaped plate 11, the end of the threaded rod 12 is fixedly connected to the first bevel gear 10, and the side wall of the threaded rod 12 is provided with a moving block 13 threadedly connected thereto. The moving block 13 is abutted against the inner rear side wall of the U-shaped plate 11 to prevent the moving block 13 from rotating with the threaded rod 12. The side wall of the moving block 13 is fixedly connected to a fixed block 16 extending into the groove 15, that is, the moving block 13 is driven to move horizontally under the rotation of the threaded rod 12, and then the punching head 14 is fixed by the joint action of the moving block 13 and the fixed block 16.

[0036] Example 5

[0037] Based on embodiment one, the drive assembly includes a motor 9 installed on the inner rear side wall of the U-shaped plate 11, and the end of the output shaft of the motor 9 is fixedly connected to the second bevel gear 18, and the second bevel gear 18 is engaged with the first bevel gear 10, that is, the second bevel gear 18 is driven to rotate by the driving action of the motor 9, and then engaged with the first bevel gear 10 for transmission, thereby ensuring the subsequent fixing work.

[0038] Example 6

[0039] Based on embodiment one, the opposite side walls of the two moving blocks 13 are fixedly connected with a pressing block 17, and the two pressing blocks 17 are both pressed against the upper end of the punching head 14, that is, when the pressing block 17 is pressed against the punching head 14, the punching head 14 is limited so that it is stably located on both sides of the moving block 13 and cannot move upward, and the punching head 14 is pressed against the inner rear side plate of the U-shaped plate 11, and can work together to limit the punching head 14, so that the two fixed blocks 16 can correspond horizontally to the two grooves 15 respectively, and then the fixed block 16 and the groove 15 connected by a snap are used to fix the punching head 14.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
