Description

Technical Field

[0001] This utility model relates to the field of handle production technology, and in particular to a bending device for producing curved handles. Background Technology

[0002] In the production of curved handles, bending is a crucial forming process, its quality directly affecting the handle's appearance, curvature consistency, and installation suitability. Currently, common bending processes mostly employ traditional mechanical or hydraulic bending equipment, using an upper die pressing down and a lower die supporting the material to plastically deform the sheet metal. However, these types of equipment still have several problems in practical use:

[0003] First, due to the lack of an effective board positioning mechanism, the board is prone to slippage or displacement during bending, resulting in inaccurate bending position and asymmetrical arc surface, which affects product consistency and yield. This problem is particularly prominent for curved handles with high arc accuracy requirements.

[0004] Secondly, traditional bending equipment usually separates the bending and unloading processes. After bending, the parts need to be picked up manually or transferred with the help of an additional robotic arm. This not only increases the labor intensity of the operators but also reduces production efficiency, making it difficult to meet the requirements of modern production lines for continuity and automation.

[0005] In addition, although some existing equipment attempts to use pneumatic or vacuum adsorption methods for auxiliary positioning, there are still problems such as complex structure and poor coordination with bending action. It is impossible to achieve stable adsorption and reliable demolding throughout the bending process. In particular, during the return process, products often fall off or deviate in position, affecting subsequent material collection and stacking.

[0006] Therefore, it is necessary to design an arc-shaped handle bending device that is structurally sound, easy to operate, combines bending and automatic feeding functions, and can reliably position the sheet material during the bending process, in order to improve product quality and production efficiency. Utility Model Content

[0028] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.

[0029] This utility model provides an improved bending device for producing curved handles. The technical solution of this utility model is as follows:

[0030] like Figure 1-4 As shown, a bending device for producing arc-shaped handles includes a main body 1, a stamping and bending assembly, and a bending head 4.

[0031] The stamping and bending assembly includes a lower upright plate 6 fixed to the bottom side of the main body 1 of the equipment. A lower die base 601 is fixedly installed on the top of the lower upright plate 6. A bending die cavity 602 is opened on the lower die base 601. It should be noted that the lower die base 601 and the bending pressure head 4 can be replaced according to the shape of different arc handles to improve versatility and adaptability; for example Figure 1As shown, when the bending head 4 moves downward, it can press the raw material, causing the raw material to bend and fit against the inner wall of the bending die cavity 602, thereby completing the pressing and bending process of the raw material.

[0032] The bending head 4 is adapted to the bending die cavity 602. The bending head 4 is equipped with a negative pressure adsorption component. The negative pressure adsorption component is activated when the bending operation is completed, so as to adsorb the bent material under negative pressure. As the bending head 4 moves upward, it can directly adsorb, lift and unload the product. The top of the bending head 4 is connected to a hydraulic drive component, which is used to push and pull the bending head 4.

[0033] Furthermore, the hydraulic drive assembly includes a mounting plate 101 fixedly installed on the top of the equipment body 1, and a hydraulic rod 2 is fixedly connected to one side of the mounting plate 101, with the extension rod of the hydraulic rod 2 movably penetrating through the top of the equipment body 1.

[0034] Furthermore, a connecting slider 201 is fixedly installed at the end of the extension rod of the hydraulic rod 2; with the above structure, when the hydraulic rod 2 is running, it can directly drive the connecting slider 201 to move vertically.

[0035] As a further embodiment of this utility model, the negative pressure adsorption assembly includes a connecting column 401 fixedly connected to the top of the bending head 4. The connecting column 401 and the bending head 4 are provided with an air cavity 404. The inside of the bending head 4 is provided with a mother cavity 405 that communicates with the air cavity 404. The bottom of the bending head 4 is provided with a plurality of negative pressure ports 406 that communicate with the mother cavity 405, and a rubber gasket 407 is attached to the opening of the negative pressure port 406.

[0036] Furthermore, a small air pump 7 is fixedly installed on one side of the connecting column 401, and the input end of the small air pump 7 is connected to the air chamber 404. Through the above structure, when the small air pump 7 is running, it can continuously keep the air chamber 404 and the mother chamber 405 in a negative pressure state, and achieve adsorption of the product through the negative pressure port 406 and the rubber gasket 407.

[0037] Furthermore, a sliding plate 403 is fixedly connected to the top of the connecting column 401, and the sliding plate 403 is slidably connected to the connecting slider 201. Symmetrically arranged guide columns 402 are fixed on both sides of the connecting column 401, and guide rail grooves 3 are fixed on both inner walls of the main body 1. The guide columns 402 and guide rail grooves 3 form a sliding fit. Through the above structure, when the connecting slider 201 moves vertically, under the guidance of the guide columns 402 and guide rail grooves 3, the bending head 4, the connecting column 401, and the sliding plate 403 move synchronously along their trajectory, facilitating convenient subsequent product unloading.

[0038] Furthermore, an operation control panel 5 is fixedly installed on one side of the main body 1 of the equipment. The operation control panel 5 is electrically connected to the small air pump 7 and the hydraulic rod 2. It should be noted that in this application, the small air pump 7 only stops operating when the hydraulic rod 2 is fully retracted. During the extension and retraction of the hydraulic rod 2, the small air pump 7 is started, and by continuously generating negative pressure, in conjunction with the air chamber 404, the mother chamber 405 and the negative pressure port 406, the product is adsorbed. When the hydraulic rod 2 is extended, the negative pressure can be used to first adsorb and fix the middle of the raw material to prevent the raw material from shifting when bending. When the hydraulic rod 2 is retracted, the already bent product is adsorbed and lifted synchronously. When fully retracted, the small air pump 7 stops starting, and the product falls on its own under its own gravity to the external transmission belt device set below, realizing convenient unloading.

[0039] The specific working method is as follows: During use, the hydraulic rod 2 is in the retracted state, and the bending head 4 is located on the upper part of the lower die base 601; the small air pump 7 is not started, and the negative pressure port 406 has no suction force; the plate to be bent is placed above the bending die cavity 602 of the lower die base 601; the hydraulic rod 2 and the small air pump 7 are started through the operation control panel 5; the small air pump 7 starts to work, and a negative pressure is formed through the air chamber 404, the mother chamber 405 and the negative pressure port 406, which adsorbs the middle of the plate and prevents it from shifting; then, the hydraulic rod 2 pushes the connecting slider 201 downward, and the connecting column 401 and the bending head 4 move downward through the slide plate 403; during the process, the guide column 402 slides along the guide rail groove 3 to ensure the stability of the movement trajectory; the bending head 4 presses into the bending die cavity 602 and bends the plate into shape;

[0040] After bending is completed, the hydraulic rod 2 begins to retract, causing the bending head 4 to move upward. At this time, the small air pump 7 continues to work, and the negative pressure port 406 continues to absorb the bent handle product, causing it to move upward with the pressure head; when the bending head 4 rises to the highest point, the operation control panel 5 controls the small air pump 7 to stop working, the negative pressure disappears, and the finished product automatically falls off under the action of gravity, landing on the conveyor belt below the equipment, completing the unloading process;

[0041] Finally, the hydraulic rod 2 retracts completely, the bending head 4 returns to its initial position, and the equipment returns to standby mode, ready for the next bending operation.

[0042] The entire process, through the synergistic effect of hydraulic drive and negative pressure adsorption, achieves automated operation from positioning and bending to unloading, which not only improves production efficiency but also ensures product consistency and quality.

[0043] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
