Description

Technical Field

[0001] This invention relates to the field of automotive hinge processing technology, specifically to a non-marking bending device for automotive hinge processing. Background Technology

[0002] Automotive hinge manufacturing refers to the process of using metal materials as raw materials and transforming them into hinge assemblies or parts that meet the connection and opening / closing requirements of automotive door bodies, hoods, trunk lids, seats, and other components through a series of mechanical processing and forming processes such as shearing, stamping, bending, welding, and surface treatment.

[0003] The indentation-free bending device for automotive hinge processing is a specialized piece of equipment designed specifically for the bending process of automotive hinge parts. Its core principle is to avoid rigid compression contact between the upper and lower dies and the workpiece surface during sheet metal bending through floating supports, elastic buffers, multi-segment molds, or auxiliary forming structures. This ensures that the workpiece surface is free of visible indentations, scratches, or plastic deformation while achieving the target bending angle, meeting the stringent requirements of automotive hinges for appearance quality and assembly precision. However, existing indentation-free bending devices are typically placed on a platform, and not all platforms are flat. Since indentation-free bending of automotive hinges is a highly precise operation, tilting the device will affect the processing quality. Summary of the Invention

[0004] The purpose of this invention is to provide a non-marking bending device for automotive hinge processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a non-marking bending device for automotive hinge processing, comprising:

[0006] The machine body includes a non-marking bending machine, the surface of which is provided with a placement block;

A connecting screw is fixedly connected to the surface of the leveling knob. A rotating block is fixedly connected to the end of the connecting screw away from the leveling knob. An inclined block is fitted onto the surface of the rotating block. A movable groove is formed on the surface of the leveling platform. A guide rod is fixedly connected to the surface of the movable groove. A wedge is movably connected to the surface of the guide rod. A connecting shaft is fixedly connected to the surface of the non-marking bending machine.

[0008] Preferably, the leveling knobs are symmetrically distributed in two sets on the surface of the leveling platform, the connecting screws are rotatably connected to the surface of the leveling platform through the leveling knobs, the connecting screws are threaded onto the surface of the leveling platform, and the rotating block is rotatably connected to the inside of the inclined block through the connecting screws.

[0009] Preferably, the movable grooves are symmetrically arranged in two sets on the surface of the leveling platform, and the inclined block is movably connected to the interior of the movable groove through a rotating block.

[0010] Preferably, the wedge is abutted against the surface of the inclined block, the side of the wedge that contacts the inclined block is inclined, the wedge is movably connected to the surface of the inclined block and the movable groove, the wedge is movably connected to the surface of the guide rod through the movable groove, and a limit groove is formed on the surface of the wedge.

[0011] Preferably, the connecting shafts are symmetrically distributed in two sets on the surface of the non-marking bending machine. The connecting shafts are movably connected to the surface of the wedge block and the leveling platform. The connecting shafts are rotatably connected to the surface of the wedge block. The non-marking bending machine is movably connected to the surface of the leveling platform through the connecting shafts.

[0012] Preferably, the replacement mechanism includes a bending block, which is inserted into the surface of the placement block. The surface of the bending block has a slot, the surface of the placement block has an installation groove, the surface of the placement block is fixedly connected to a connecting groove, the surface of the connecting groove is movably connected to a handle, the surface of the handle is fixedly connected to a rod, the surface of the rod is fixedly connected to a limit block, and the surface of the rod is wound with a damping spring.

[0013] Preferably, the connecting grooves are symmetrically distributed in two sets on the surface of the placement block, the insert rod is movably connected to the surface of the mounting groove via a pull handle, and the limiting block is movably connected to the interior of the connecting groove via the insert rod.

[0014] Preferably, the bending block is connected to the surface of the mounting slot and the placement block by interlocking. The slots are symmetrically arranged in two sets on the surface of the bending block. The two ends of the damping spring are fixedly connected to the inside of the connecting slot and the surface of the limiting block. The limiting block is movably connected to the inside of the connecting slot by the damping spring. The insert rod is connected to the surface of the slot by interlocking through the damping spring. The bending block is fixedly connected to the surface of the placement block by the insert rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By connecting the non-marking bending machine to the bubble level, the machine's horizontality can be observed. Then, by connecting the leveling platform and the leveling knob, if the machine is not horizontal, the leveling knob on the downward-tilting side can be rotated for leveling. The leveling knob is connected to the connecting screw, which in turn connects to the rotating block. The rotating block moves as it rotates. The rotating block and the inclined block are connected, as are the leveling platform and the movable groove. The inclined block moves within the movable groove following the rotating block's rotation. The wedge moves as the inclined block moves. The guide rod guides the wedge's movement. Finally, the wedge and the connecting shaft, and the connecting shaft and the non-marking bending machine, lift the downward-tilting side of the machine along with the wedge until the machine is completely horizontal, ensuring the machine's processing accuracy.

[0017] 2. By connecting the handle and the insert rod, and the mounting slot and the insert rod, the movable handle can move the insert rod away from the surface of the mounting slot, allowing the bending block to be inserted and installed on the surface of the placement block. Then, by connecting the insert rod and the limiting block, and the connecting slot and the limiting block, the limiting block can move inside the connecting slot as the insert rod moves, thus limiting the movement position of the insert rod. The damping spring deforms accordingly. By connecting the bending block and the placement block, and the placement block and the mounting slot, the bending block can be inserted and installed on the surface of the placement block through the mounting slot. By connecting the damping spring and the limiting block, and the insert rod and the limiting block, the damping spring can restore its original shape, causing the limiting block and the insert rod to reset. Finally, by connecting the insert rod and the slot, the insert rod can be reset and inserted into the slot, thus fixing the installation position of the bending block. Conversely, the bending block can be disassembled and replaced, achieving the effect of replacing the chamfered surface of the placement block. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-6 One embodiment provided by the present invention:

[0027] A non-marking bending device for automotive hinge processing includes:

[0028] The machine body includes a non-marking bending machine 1. A placement block 11 is provided on the surface of the non-marking bending machine 1. Both the non-marking bending machine 1 and the placement block 11 are existing products and are not considered as technical protection points of this application. They will not be described in detail here.

[0029] The leveling mechanism includes a bubble level 2, which is fixedly connected to the surface of the non-marking bending machine 1 for observing whether the non-marking bending machine 1 is level. A leveling platform 21 is provided below the non-marking bending machine 1 for leveling it. A leveling knob 22 is rotatably connected to the surface of the leveling platform 21 to drive the connecting screw 23 to rotate. The connecting screw 23 is fixedly connected to the surface of the leveling knob 22 for connecting the leveling knob 22 and the rotating block 24. The end of the connecting screw 23 away from the leveling knob 22 is fixedly connected to the rotating block 24 for the inclined block 25 to follow the connecting screw 24. When moving with the rotation of the connecting screw 23, it does not need to rotate with the connecting screw 23. The surface of the rotating block 24 is fitted with an inclined block 25, which is used to drive the wedge block 28 to move by its own movement. The surface of the leveling platform 21 is provided with a movable groove 26 for the movement of the inclined block 25 and the wedge block 28. The surface of the movable groove 26 is fixedly connected with a guide rod 27, which is used to guide the movement of the wedge block 28. The surface of the guide rod 27 is movably connected with the wedge block 28, which is used to connect the connecting shaft 29. The surface of the non-marking bending machine 1 is fixedly connected with the connecting shaft 29, which is used to connect the wedge block 28 and the non-marking bending machine 1.

[0030] Furthermore, the leveling knobs 22 are symmetrically distributed in two sets on the surface of the leveling platform 21. The distribution of the two sets of leveling knobs 22 allows the non-marking bending machine 1 to be leveled by rotating the leveling knobs 22 on different sides. The connecting screw 23 is rotatably connected to the surface of the leveling platform 21 through the leveling knobs 22. The connecting screw 23 is threaded onto the surface of the leveling platform 21. The rotating block 24 is rotatably connected to the inside of the inclined block 25 through the connecting screw 23. The leveling bubble 2 is used to observe whether the non-marking bending machine 1 is level. If the non-marking bending machine 1 is not level, the leveling knob 22 on the side that is tilted downwards can be rotated to drive the connecting screw 23 to rotate, thereby driving the rotating block 24 to rotate and move at the same time, thereby pushing the inclined block 25 to move inside the movable groove 26. The connecting screw 23 is threaded onto the leveling platform 21, so it is a self-locking structure and will not rotate under the action of no external force.

[0031] Furthermore, two sets of movable grooves 26 are symmetrically opened on the surface of the leveling platform 21. The two sets of movable grooves 26 are connected to two sets of inclined blocks 25 and wedges 28. The inclined blocks 25 are movably connected to the inside of the movable grooves 26 through the rotating block 24. The inclined blocks 25 move inside the movable grooves 26 as the connecting screw 23 rotates.

[0032] Furthermore, the wedge 28 abuts against the surface of the inclined block 25, and the side of the wedge 28 that contacts the inclined block 25 is inclined. The wedge 28 is movably connected to the surface of the inclined block 25 and the movable groove 26, and the wedge 28 is movably connected to the surface of the guide rod 27 through the movable groove 26. A limit groove is formed on the surface of the wedge 28. The wedge 28 is lifted as the inclined block 25 moves. The guide rod 27 is configured to guide the movement of the wedge 28 and prevent the wedge 28 from deviating.

[0033] Furthermore, the connecting shafts 29 are symmetrically distributed in two sets on the surface of the non-marking bending machine 1. The connecting shafts 29 are movably connected to the surface of the wedge block 28 and the leveling platform 21. The connecting shafts 29 are rotatably connected to the surface of the wedge block 28. The non-marking bending machine 1 is movably connected to the surface of the leveling platform 21 through the connecting shafts 29. The connecting shafts 29 are lifted up as the wedge block 28 is lifted, thereby raising the non-marking bending machine 1 to the side that is tilted downward. The hinged connection between the wedge block 28 and the connecting shafts 29 ensures that the non-marking bending machine 1 can tend to be horizontal, so that the position of the non-marking bending machine 1 is horizontal, avoiding the impact on the processing accuracy of the automotive hinge due to the unevenness of the platform surface on which the non-marking bending machine 1 is placed.

[0034] Furthermore, the replacement mechanism includes a bending block 3, which is inserted into the surface of the placement block 11 for replacing the chamfered end of the placement block 11. The surface of the bending block 3 has a slot 31 for inserting the rod 35. The surface of the placement block 11 has an installation groove 32 for installing the bending block 3. The surface of the placement block 11 is fixedly connected to a connecting groove 33 for limiting the movement of the handle 34. The surface of the connecting groove 33 is movably connected to the handle 34 for moving the rod 35. The surface of the handle 34 is fixedly connected to the rod 35 for inserting into the slot 31 to limit the position of the bending block 3. The surface of the rod 35 is fixedly connected to a limit block 36 for limiting the movement of the rod 35. The surface of the rod 35 is wound with a damping spring 37 for resetting the rod 35 to insert into the slot 31 through its own deformation.

[0035] Furthermore, the connecting grooves 33 are symmetrically distributed in two sets on the surface of the placement block 11. The symmetrical distribution of the two sets of connecting grooves 33 fixes both sides of the bending block 3, improving the stability of the connection between the bending block 3 and the placement block 11. The insertion rod 35 is movably connected to the surface of the mounting groove 32 through the pull handle 34. The limiting block 36 is movably connected to the inside of the connecting groove 33 through the insertion rod 35. Pulling the pull handle 34 causes the insertion rod 35 to leave the surface of the mounting groove 32, so that the bending block 3 can be inserted and installed on the surface of the placement block 11. The limiting block 36 moves inside the connecting groove 33 as the insertion rod 35 moves, thereby limiting the movement position of the insertion rod 35. The damping spring 37 deforms accordingly.

[0036] Furthermore, the bending block 3 is connected to the surface of the mounting groove 32 and the placement block 11 by interlocking. The slots 31 are symmetrically arranged in two sets on the surface of the bending block 3. The two ends of the damping spring 37 are fixedly connected to the inside of the connecting groove 33 and the surface of the limiting block 36. The limiting block 36 is movably connected to the inside of the connecting groove 33 by the damping spring 37. The insertion rod 35 is connected to the surface of the slot 31 by interlocking through the damping spring 37. The bending block 3 is fixedly connected to the surface of the placement block 11 by the insertion rod 35. Then, the bending block 3 is inserted and installed in the mounting groove 32. The restriction on the pull handle 34 is released. The damping spring 37 drives the limiting block 36 to move inside the connecting groove 33 to restore its original shape, so that the insertion rod 35 is reset and inserted into the slot 31, thereby fixing the installation position of the bending block 3. Conversely, the bending block 3 can be disassembled and replaced so that different chamfering blocks can be used to process the bending end of the car hinge into different angles for use.

[0037] Working principle: When using the non-marking bending machine 1, first pull the handle 34 to move the insert rod 35 away from the surface of the mounting slot 32, so that the bending block 3 can be inserted and installed on the surface of the placement block 11. The limiting block 36 moves inside the connecting slot 33 following the movement of the insert rod 35, thereby limiting the movement position of the insert rod 35. The damping spring 37 deforms accordingly. Then, insert the bending block 3 into the mounting slot 32 and release the restriction on the handle 34. The damping spring 37 moves the limiting block 36 inside the connecting slot 33 to return to its original shape, so that the insert rod 35 resets and inserts into the slot 31, thereby fixing the installation position of the bending block 3. Conversely, the bending block 3 can be disassembled and replaced to use different chamfering blocks to process the bending end of the car hinge into different angles for use. Then, use the level bubble 2 to observe whether the non-marking bending machine 1 is level. If there is no mark, the machine will be level. The non-marking bending machine 1 is not horizontal. The leveling knob 22, which is tilted downwards, rotates to drive the connecting screw 23 to rotate, thereby causing the rotating block 24 to rotate and move simultaneously. This pushes the inclined block 25 to move inside the movable groove 26. The inclined block 25 moves inside the movable groove 26 following the rotation of the connecting screw 23. The wedge block 28 is lifted up as the inclined block 25 moves. The guide rod 27 is set to guide the movement of the wedge block 28 and prevent the wedge block 28 from deviating. The connecting shaft 29 is lifted up as the wedge block 28 is lifted, thereby raising the tilted downward side of the non-marking bending machine 1. The hinged connection between the wedge block 28 and the connecting shaft 29 ensures that the non-marking bending machine 1 can tend to be horizontal, so that the position of the non-marking bending machine 1 is horizontal, avoiding the impact on the processing accuracy of the automotive hinge due to the unevenness of the platform on which the non-marking bending machine 1 is placed.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
