Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hardware part bending, and specifically relates to a hardware part bending machine. Background Art
[0002] Hardware parts refer to various small metal parts or standard parts made of metal materials (such as iron, copper, aluminum, stainless steel, etc.) through processing technologies such as stamping, casting, cutting, and bending. They are widely used in industries such as machinery, electronics, construction, furniture, and automobiles. The bending process is one of the key processes for shaping metal components. Especially for workpieces with complex bending structures such as a "Ji" shape in the middle and an "Ba" shape at both ends, this kind of hardware part with such a shape can be used as a buckle in some hardware furniture and luggage accessories, and can be snapped into the corresponding slot to realize the connection and fixation of components.
[0003] Reference patent document: Patent Publication No. CN106734400A, Patent Publication Date: May 31, 2017, discloses an automobile hardware part bending machine, including a bending machine body, a bending punch, and a hydraulic mechanism. A lower plate body is provided at the bottom of the bending machine body, and the lower plate body is connected to a shock pad through lower cylindrical pins on both left and right sides. The shock pad is connected to an upper plate body through upper cylindrical pins on both left and right sides, and a vertical plate is provided at the top of the upper plate body. The vertical plate is connected to a bending groove seat by welding, and blanking mechanisms are provided on both sides of the vertical plate. The punch base is provided at the rear of the top of the upper plate body, and a hydraulic mechanism is provided at the top of the punch base. In this bending machine, a design with two material retaining plates arranged in the front and back is adopted at the top of the bending groove seat. The pressing plate is connected to the hydraulic mechanism through a hydraulic rod, and the pressing plate is arranged on both left and right sides of the hydraulic mechanism and on the same axis as the blanking mechanism, effectively solving the problems of poor positioning, unstable fixation, large bending error, and inability to meet the use requirements.
[0004] Based on the search for the patent number and combined with the deficiencies in the prior art, it is found that:
[0005] Traditional hardware part bending equipment mainly uses hydraulic or mechanical bending machines to bend metal plates at a single angle through a mold. However, in actual production, many hardware parts such as brackets, connectors, and clamping blocks require complex multi-angle bending. For example, a structure with a "Ji" shape in the middle and an
[0006] "Ba" shape at both ends, which requires multiple adjustments of the workpiece position and multiple bending operations to form its structure, resulting in low work efficiency. And due to multiple adjustments of the workpiece position, the bending angle and position are prone to change, resulting in the bent workpiece not meeting the use requirements.
[0007] Therefore, the utility model provides a hardware part bending machine. Content of the Utility Model
[0008] To address the problem that traditional hardware bending equipment requires multiple adjustments to the workpiece position for bending at multiple angles, resulting in low work efficiency and difficulty in guaranteeing bending accuracy, the purpose of this utility model is to provide a hardware bending machine.

A drive assembly is provided on one side of the movable frame. A fixed platform is fixedly mounted on one side of the top of the processing table. Two limit rods are provided on the upper part of the fixed platform.

[0017] Beneficial effects
[0018] The utility model provides a hardware part bending machine. Compared with the prior art, it has the following beneficial effects:

Moreover, when the limiting rod is worn, it can be quickly disassembled and replaced, reducing the equipment maintenance time and cost, and enhancing the flexibility and practicality of the bending machine in actual production.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0029] Please refer to Figure 1-6 , the present invention provides a technical solution: a hardware bending machine, including a processing table 1 and a workpiece to be processed 3. The workpiece to be processed 3 is as Figure 6 shown, which is the shape after processing. The middle part is a "U" - shaped structure, and both ends are in an "eight" - shaped structure. A bending mechanism 2 is provided in the middle of the top surface of the processing table 1 for bending metal hardware. The bending mechanism 2 includes:
[0030] The execution component 21 includes a lower rotary table 215 rotatably mounted on the center of the top surface of the machining table 1. An upper rotary table 216 is rotatably mounted on the center of the top of the lower rotary table 215. Both the upper rotary table 216 and the lower rotary table 215 have a bent rod 217 on one side of their top surfaces, and a positioning rod 218 on the other side of the top surface of the upper rotary table 216. A lower rotating shaft 2151 is fixedly mounted on the center of the bottom of the lower rotary table 215, and an upper rotating shaft 2161 is fixedly mounted on the center of the bottom of the upper rotary table 216. The upper rotating shaft 2161 slides through the center of the lower rotary table 215 and the lower rotating shaft 2151. A frame 211 is fixedly mounted on the center of the bottom of the machining table 1. A lower gear 2141 is rotatably mounted on the center of the top of the frame 211, and an upper gear 2151 is rotatably mounted on the top of the lower gear 2141. 31. The bottom end of the upper rotating shaft 2161 slides through the middle of the upper gear 2131 and is fixedly installed at the top middle of the lower gear 2141. The bottom end of the lower rotating shaft 2151 is fixedly installed at the top middle of the upper gear 2131. A movable frame 212 is slidably attached to the middle of the frame 211. An upper gear plate 213 is fixedly installed on the upper side of one side of the movable frame 212. The upper gear 2131 and the upper gear plate 213 are meshed with each other. A lower gear plate 214 is fixedly installed on the other side of the upper part of the movable frame 212. The lower gear plate 214 and the lower gear 2141 are meshed with each other. A drive assembly is provided on one side of the movable frame 212. A fixed table 219 is fixedly installed on one side of the top of the processing table 1. Two limit rods 2191 are provided on the upper part of the fixed table 219.
[0031] The quick-release assembly 22 is located on the upper part of the fixed platform 219 and is used to quickly adjust the position of its limit rod 2191.
[0032] The quick-installation assembly 22 includes multiple slots 221 on the upper part of the fixing platform 219. Each slot 221 has a screw 222 fixedly installed in the middle. Two limiting rods 2191 are threaded onto the upper part of the screw 222. By rotating the limiting rods 2191, they can move up and down along the screw 222, thereby realizing the quick adjustment of the position of the limiting rods 2191 on the upper part of the fixing platform 219, which is suitable for bending in different requirements. At the same time, it can facilitate the replacement of worn limiting rods 2191.
[0033] Two symmetrically distributed grooves 2111 are provided in the middle of the frame 211. The two sides of the movable frame 212 are slidably locked in the middle of the grooves 2111. The grooves 2111 have a T-shaped cross-section, and the two sides of the movable frame 212 are equipped with T-shaped structures that match the grooves 2111. This allows the two sides of the movable frame 212 to be tightly locked in the middle of the grooves 2111, thereby ensuring the stability of the movable frame 212 sliding in the middle of the frame 211 and effectively reducing shaking and displacement during movement.
[0034] The driving component includes a cylinder 2121 fixedly installed on one side of the bottom end of the processing table 1.

[0035] On the top side of both the upper turntable 216 and the lower turntable 215, key shafts 223 corresponding to the bending rods 217 and positioning rods 218 are fixedly installed. By sliding and clamping the lower parts of the bending rods 217 and positioning rods 218 on the upper parts of the key shafts 223 and fixing them by friction, it is convenient to install and fix the bending rods 217 and positioning rods 218.
[0036] Four uniformly distributed support columns 11 are fixedly installed at the bottom end of the processing table 1. A plurality of uniformly distributed mounting holes are opened in the lower parts of the four support columns 11. Through the support columns 11 and the mounting holes, the processing table 1 can be quickly installed and fixed, ensuring the bending stability of the processed workpiece 3.
[0037] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0038] During operation, when bending, the processed workpiece 3 to be bent is horizontally placed between its two bending rods 217 and positioning rods 218, and the middle position of the processed workpiece 3 corresponds to the position of the positioning rod 218. At this time, the cylinder 2121 is started to drive the movement of the moving frame 212, and then the upper tooth plate 213 and the lower tooth plate 214 can be driven to move synchronously, and then the upper gear 2131 and the lower gear 2141 meshed with them can be driven to rotate synchronously and in opposite directions. Then, under the transmission of its upper rotating shaft 2161 and lower rotating shaft 2151, the upper turntable 216 and the lower turntable 215 rotate synchronously and in opposite directions, that is, the two bending rods 217 are driven to move synchronously. Then, under the limitation of the positioning rod 218, the processed workpiece 3 is bent around the positioning rod 218. When the two ends of the processed workpiece 3 encounter the limiting rods 2191, the middle parts of the two ends of the processed workpiece 3 will be bent synchronously around its bending rods 217, making the middle section of the processed workpiece 3
[0039] in a "U" - shaped structure, and the two ends are in an "eight" - shaped structure. By rotating the two limiting rods 2191, the positions of the two limiting rods 2191 can be adjusted, and then the inclination angle of the "eight" - shaped structure at both ends can be adjusted during bending, so as to be suitable for bending requirements of different needs. At the same time, it is convenient to replace the worn limiting rods 2191.
