Description

Technical Field

[0001] This utility model relates to the technical field of protective bracket production tools, and in particular to a bending device used in the production and processing of heavy truck protective brackets. Background Technology

[0002] As a key component for ensuring driving safety, heavy truck protective brackets have extremely high requirements for bending angle and position accuracy, which directly affects the subsequent installation compatibility. Traditional heavy truck protective bracket bending devices lack a dedicated angle adjustment structure, resulting in obvious defects in angle control and position positioning, which seriously restricts bending accuracy. Traditional bending devices require adjusting the bracket angle by moving the entire bracket or replacing positioning blocks of different sizes. The adjustment method lacks fine-tuning capabilities. For example, when adjusting the bending angle from 90° to 91°, traditional devices cannot achieve this through fine adjustments. They can only approximate the adjustment by replacing shims with minimal thickness differences or raising a portion of the bracket. This method is not only cumbersome but also prone to uneven stress on the bracket, leading to localized deformation after bending. Furthermore, the adjustment process requires repeated trial bending and measurement, making it impossible to achieve the design standard on the first attempt, severely impacting mass production efficiency. Therefore, these problems need to be addressed. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 6 The bending device for manufacturing heavy-duty truck protective brackets in this utility model includes a body 1. A through-type processing groove is horizontally opened on the side wall of the body 1. A lower pressing block is slidably provided on one side of the top of the processing groove. A hydraulic cylinder 2 is fixedly connected to the side wall of the lower pressing block. The hydraulic cylinder 2 facilitates precise adjustment of the bending force according to the material and thickness of the protective bracket, avoiding insufficient force leading to incomplete bending or excessive force damaging the bracket. An upper die mounting seat 3 is fixedly connected to one end of the bottom of the lower pressing block. The upper die mounting seat 3 facilitates efficient transmission of the driving force of the hydraulic cylinder 2 to the bending knife 5. A bending component is installed on the upper die mounting seat 3. A lower die mounting seat 8 is fixedly connected to the bottom of the processing groove. An adjustment component for changing the bracket angle is installed on the bottom side wall of the processing groove. The lower die mounting seat 8 facilitates accurate installation of the bending die 9 and high alignment accuracy with the bending knife 5.

[0015] In this utility model, the adjusting component includes a mounting plate disposed on the bottom side wall of the processing tank and a push plate 14 slidably disposed on the bottom of the processing tank. Two motors 10 are mounted on one side of the mounting plate, and threaded rods 11 are coaxially fixed to the output ends of the two motors 10 extending to the other side of the mounting plate. Push sleeves 12 are sleeved on the other end of the threaded rods 11, and sliding hinge seats 13 are hinged on the two push sleeves 12. The adjusting component facilitates the adjustment of the placement angle and position of the heavy truck protective bracket, providing precise positioning for bending processing. A slide groove is opened on one side of the push plate 14, and the sliding hinge seat 13 is slidably engaged in the slide groove. A baffle plate 16 is provided on the other side of the push plate 14, and two buffer springs 15 are installed between the push plate 14 and the baffle plate 16. The baffle plate 16 facilitates the positioning and limiting of the bracket, ensuring accurate bending position. The bending component includes two connecting seats 4 fixed to the upper mold mounting base 3 and two slidingly disposed on the two... The bending blade 5 inside the connecting seat 4 is screwed to the top of the connecting seat 4 with a bolt for fixing. The bending blade 5 has a connecting hole 7 in the middle that extends to the outer wall of the connecting seat 4. A locking wedge 6 is rotatably engaged in the connecting hole 7. The bending component helps to enhance the fixing strength of the bending blade 5 and prevent the bending blade 5 from loosening due to impact during bending. The lower die mounting seat 8 has multiple positioning holes on its top. The lower die mounting seat 8 is equipped with a bending die 9. The bottom of the bending die 9 is fixed with a positioning pin that matches the positioning hole. Locking bolts are screwed on both sides of the top of the bending die 9. The ends of the locking bolts abut against the lower die mounting seat 8. The bending die 9 works in coordination with the bending blade 5 to ensure that the protective bracket is regular in shape and accurate in size after bending. The other end of the bottom of the lower pressure block has a receiving groove for accommodating the adjustment component. The receiving groove helps to prevent spatial interference between the lower pressure block and the adjustment component when it moves downward.

[0016] Working principle: When using this utility model, firstly, connect each electrical component in this application to the power supply. Then, according to the bending angle and thickness of the protective bracket to be processed, select the matching bending die 9 and bending blade 5. Precisely align the bending die 9 with the positioning hole of the lower die mounting base 8 through the bottom positioning pin, and tighten the locking bolt on the top of the die to ensure the die is firmly fixed. Slide the bending blade 5 between the two connecting seats 4 of the upper die mounting base 3, tighten the fixing bolt on the top of the connecting seat 4 to initially fix the blade, and then insert the locking wedge 6 through the connecting hole 7 and rotate to lock it, achieving double fixing of the bending blade 5 and preventing the blade from being damaged during bending. The displacement is checked, and the receiving groove at the other end of the bottom of the lower pressure block is inspected to ensure that there are no foreign objects inside and that the size of the groove is compatible with the movement trajectory of the adjusting component, so as to reserve sufficient space for the subsequent lifting and lowering of the lower pressure block and avoid spatial interference. Then, the operator places the protective bracket to be bent on the bending die 9 of the lower die mounting base 8, so that one end of the bracket is in contact with the reference surface of the bending die 9; the adjusting component of the bottom side wall of the processing tank is activated, and the two motors 10 operate synchronously, driving the threaded rod 11 to rotate. The threaded rod 11 drives the push sleeve 12 on the surface to move axially. The push sleeve 12 drives the push plate 14 to slide along the bottom of the processing tank through the sliding hinge seat 13. Until the baffle plate 16 on one side of the push plate 14 is in contact with the other end of the bracket, the buffer spring 15 between the push plate 14 and the baffle plate 16 is compressed to generate elastic force. This not only avoids hard contact that could scratch the bracket surface, but also adaptively adjusts the limiting force according to the bracket thickness to ensure stable clamping of the bracket. If it is necessary to adjust the bending angle of the bracket, the speed difference between the two motors 10 can be controlled to create a slight difference in the pushing distance of the threaded rods 11 on both sides. The sliding hinge seat 13 slides flexibly in the groove of the push plate 14, causing the baffle plate 16 to deflect slightly, thereby achieving precise micro-adjustment of the bracket angle until the bracket is in the optimal bending position. After confirming that the bracket is correctly positioned, the hydraulic cylinder 2 on the side wall of the machine body 1 is started. The hydraulic cylinder 2 outputs high-pressure driving force to push the lower pressure block to slide along the top of the processing tank. The lower pressure block drives the upper mold mounting seat 3 and bending knife 5 at the bottom to move downwards synchronously. The bending knife 5 continues to descend with the lower pressure block, forming a pressing structure with the bending die 9 of the lower mold. Finally, after the bracket is bent and formed, the hydraulic cylinder 2 rotates in the opposite direction, driving the lower pressure block and bending knife 5 to return to their original position. The receiving groove at the bottom of the lower pressure block moves upwards and gradually disengages from the adjusting components. The operator removes the formed protective bracket from the bending die 9. At this point, the use of the bending device for the production and processing of heavy truck protective brackets is completed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
