[0025] Specifically, the adjustment component 4 includes an adjusting screw 41, a turning handle 42, a moving block 43, a guide block 44, a damping block 45 and a threaded rod 46, wherein an adjusting screw 41 is provided at one end inside the workbench 1, a turning handle 42 is provided at one end of the adjusting screw 41, a moving block 43 is threadedly connected to the surface of the adjusting screw 41, a guide block 44 is provided below the moving block 43, a damping block 45 is abutted at the turning rod of the turning handle 42, and a threaded rod 46 is provided above the damping block 45.

[0026] By adopting the above technical solution, the turning handle 42 is rotated, and the turning handle 42 drives the adjusting screw rod 41 to rotate. The adjusting screw rod 41 rotates, and under the action of the guide block 44, the moving block 43 is driven to move, thereby driving the limit clamping assembly 5 to move, and the position of the workpiece is adjusted. After the adjustment is completed, the threaded rod 46 is rotated to move the damping block 45 downward, and the turning rod of the turning handle 42 is tightened to prevent it from loosening, so that when the device is used, it is convenient to clamp and fix the workpiece, and the position of the workpiece can be adjusted according to the bending position, thereby improving the practicality of use.

[0027] Specifically, the surface of the turning handle 42 is covered with an anti-skid rubber sleeve, and the turning block of the threaded rod 46 is also covered with an anti-skid rubber sleeve.

[0028] By adopting the above technical solution, the anti-skid rubber sleeve can prevent the surface of the turning handle 42 from skidding.

[0029] Specifically, a rubber bellows 47 is sleeved on the surface of the adjusting screw rod 41 , and a sealing plug 48 is provided above one side of the moving block 43 .

[0031] When the present embodiment is in use: the turning handle 42 is rotated, and the turning handle 42 drives the adjusting screw rod 41 to rotate. The adjusting screw rod 41 rotates, and thereby drives the moving block 43 to move under the action of the guide block 44, thereby drives the limit clamping assembly 5 to move, and adjusts the position of the workpiece. After the adjustment is completed, the threaded rod 46 is rotated to move the damping block 45 downward, and the turning rod of the turning handle 42 is tightened to prevent it from loosening, so that when the device is in use, it is convenient to clamp and fix the workpiece, and the position of the workpiece can be adjusted according to the bending position, thereby improving the practicality of use.

[0032] Example 2

[0033] The present embodiment is different from the embodiment 1 in that: specifically, the lubrication assembly 6 comprises a liquid storage tank 61, a submersible pump 62, a delivery pipe 63, an atomizing nozzle 64, a liquid adding pipe 65, a blocking cover 66, a limit block 67, a push rod 68 and a clamping spring 69, wherein a liquid storage tank 61 is arranged on one side of the limit clamping assembly 5, a submersible pump 62 is arranged inside the liquid storage tank 61, a delivery pipe 63 is arranged at one end of the submersible pump 62, an atomizing nozzle 64 is arranged at one end of the delivery pipe 63, a liquid adding pipe 65 is arranged above the liquid storage tank 61, a blocking cover 66 is arranged above the liquid adding pipe 65, a limit block 67 is arranged above the blocking cover 66, and the limit block 67 and the liquid adding pipe 65 are rotatably connected, push rods 68 are abutted on both sides below the limit block 67, and a clamping spring 69 is arranged below the push rod 68.

[0034] By adopting the above technical solution, the submersible pump 62 is started to deliver the lubricating liquid to the delivery pipe 63, and then the components of the limit clamping assembly 5 are lubricated through the atomizing nozzle 64. When lubricating liquid needs to be added, the limit block 67 is rotated to separate it from the blocking cover 66, and then the spring 69 is pressed to reset, driving the push rod 68 to move upward, thereby pushing out the blocking cover 66 and adding lubricating liquid to the inside, so that when the device is in use, it is easy to lubricate the components of the limit clamping assembly 5, thereby improving the practicality of use.

[0035] Specifically, a limit slider is provided on one side of the push rod 68, and the middle of the limit slider is slidably connected to the limit slider rod.

[0036] By adopting the above technical solution, the limit slider and the limit slide rod cooperate with each other, so as to limit the moving range of the push rod 68.

[0037] When this embodiment is in use: start the submersible pump 62 to deliver the lubricating liquid to the delivery pipe 63, and then lubricate the components of the limit clamping assembly 5 through the atomizing nozzle 64. When it is necessary to add lubricating liquid, rotate the limit clamping block 67 to separate it from the blocking cover 66, and then press the spring 69 to reset it, drive the push rod 68 to move upward, thereby pushing out the blocking cover 66 and adding lubricating liquid to the inside, so that when the device is in use, it is easy to lubricate the components of the limit clamping assembly 5, thereby improving the practicality of use.

[0038] The submersible pump 62 in the present invention is an existing disclosed technology, and the selected model is JN.

[0039] The structure and use principle of the bending component 3 and the limit clamping component 5 in the utility model have been disclosed in a limit clamping mechanism of a bending machine disclosed in Chinese patent application No. 202321359703.4. Its working principle is that the conical rotor motor is started, and the conical rotor motor drives the drive shaft and the drive gear to rotate. Since the upper transmission rack and the lower transmission rack are both engaged with the drive gear, and the guide sliders provided on the upper transmission rack and the lower transmission rack are movably connected to the inner wall of the fixed base, the driving gear can drive the upper transmission rack and the lower transmission rack to move toward each other during rotation. When the upper transmission rack and the lower transmission rack move toward each other, the adjacent clamping plate can be driven to move laterally until the clamping plate clamps the plate, so that the clamping plate limits the plate.

[0040] Working principle and use process of the utility model: When the utility model is used, the plate is placed, the limit clamping assembly 5 is used to clamp the limit position, and then the position of the plate is adjusted by the adjusting assembly 4 according to the bending position, and finally the plate can be bent by the bending assembly 3. When the parts in the limit clamping assembly 5 need to be lubricated for a long time, the lubrication assembly 6 can be used to facilitate lubrication. When the adjusting assembly 4 is in use, the turning handle 42 is rotated, and the turning handle 42 drives the adjusting screw rod 41 to rotate. The adjusting screw rod 41 rotates, and thus under the action of the guide block 44, the moving block 43 is driven to move, thereby driving the limit clamping assembly 5 to move, and the position of the workpiece is adjusted. After the adjustment is completed, the threaded rod 46 is rotated so that the damping block 4 5 is moved down to tighten the turning rod of the turning handle 42 to prevent it from loosening, so that when the device is in use, it is convenient to clamp and fix the workpiece, and the position of the workpiece can be adjusted according to the bending position, thereby improving the practicality of use. When the lubricating component 6 is in use, the submersible pump 62 is started to transport the lubricating liquid to the delivery pipe 63, and then the components of the limit clamping component 5 are lubricated through the atomizing nozzle 64. When it is necessary to add lubricating liquid, the limit clamping block 67 is rotated to separate it from the blocking cover 66, and then the spring 69 is pressed to reset, driving the push rod 68 to move up, thereby pushing out the blocking cover 66, and adding lubricating liquid to the inside, so that when the device is in use, it is convenient to lubricate the components of the limit clamping component 5, thereby improving the practicality of use.

[0041] Although 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 and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
