Description

Technical Field

[0001] This utility model relates to the field of hardware processing equipment technology, specifically a hardware parts bending machine. Background Technology

[0002] A metal bending machine is a specialized piece of equipment used for the automated bending of metal parts (such as electronic component leads and metal housing pins). In the manufacturing fields of electronics and home appliances, metal parts often need to be assembled and fixed to plastic housings through bending processes. Traditional production methods rely on manual bending, which is simple to operate but inefficient and cannot meet the needs of large-scale production.

[0003] Existing metal parts bending operations mainly rely on manual operation. Uneven force applied manually leads to inconsistent bending angles. In addition, single-piece operations are time-consuming and require frequent manual intervention, making continuous operation impossible and resulting in low production efficiency. Furthermore, repetitive operations can easily lead to worker fatigue and safety hazards, further increasing labor intensity. Therefore, a metal parts bending machine is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hardware folding machine, which has the advantages of integrated design without manual intervention, increased workpiece stability, and improved production efficiency without repetitive manual operation. It solves the problems of long single-piece operation time, inconsistent bending angles of the feet leading to poor stability, and repetitive operation causing worker fatigue.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hardware part bending machine, comprising a frame, an upper mold device and a lower mold device, wherein the upper mold device is located above the lower mold device, and both the upper mold device and the lower mold device are disposed inside the frame for processing hardware parts;

[0006] The frame includes a body, a top plate, a frame cylinder, and a cooling fan;

[0007] The upper mold device includes an upper fixed plate connected to the frame cylinder, a hardware pressing device, and pressing teeth;

[0008] The lower mold device includes a fixed base, a base plate, a slide rail fixing plate, a lower top cylinder, a folding foot cylinder, a folding foot push block, a slider, and a slide rail. The slide rail fixing plate is slidably connected to the folding foot push block through the slide rail and the slider. The lower top cylinder drives the slide rail fixing plate to rise and fall, and the folding foot cylinder drives the folding foot push block to move horizontally.

[0009] Furthermore, the piston rod of the lower cylinder (205) passes through the bottom plate and connects to the slide rail fixing plate.

[0010] Furthermore, the frame cylinder is mounted on the top plate, and a cooling fan is mounted on the back of the frame, with the air vent located at the bottom of the machine body near the control components.

[0011] Furthermore, the slide rail fixing plate is provided with a push block clearance groove, and the folding foot push block is placed in the push block clearance groove.

[0012] Furthermore, the folding foot cylinder is fixed to the side of the slide rail fixing plate, and the piston rod is connected to the folding foot push block.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This metal parts bending machine achieves efficient integrated operation by pressing the workpiece with the upper die and bending the foot simultaneously with the lower die. The guide rail ensures precise movement of the bending foot pusher, improving bending consistency. The lifting of the lower top cylinder provides support for the guide rail fixing plate, preventing workpiece displacement and enhancing stability. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The hardware folding machine in this embodiment includes a frame 300, an upper mold device 100 and a lower mold device 200. The upper mold device 100 is located above the lower mold device 200, and both the upper mold device 100 and the lower mold device 200 are arranged inside the frame 300 for processing hardware parts.

[0023] The frame 300 includes a body 301 that mounts the entire folding machine frame, a top plate 303 that supports the frame cylinder 304, and the frame cylinder 304 that drives the upper mold device 100 to descend as a whole.

[0024] The cooling fan 302 continuously cools down the heat-generating components inside the folding foot cylinder 201 and the frame 300.

[0025] The upper mold device 100 includes an upper fixed plate 101 connected to the frame cylinder 304, a hardware pressing device 102, and a pressing tooth block 103, which are used to embed into the gap of the workpiece foot. The pressing tooth block 103 increases the friction force and prevents the workpiece from shifting.

[0026] The lower mold device 200 includes a fixed base 203, the surface of which is provided with a positioning groove that matches the contour of the hardware to ensure that the workpiece is placed accurately.

[0027] The base plate 206, slide rail fixing plate 204, lower top cylinder 205, and folding foot cylinder 201 provide horizontal thrust, and the front end of the folding foot push block 202 bends and protrudes to precisely press the hardware foot position.

[0028] Slider 208 and slide rail 209 guide the folding foot pusher 202 to move in a straight line.

[0029] The slide rail fixing plate 204 is slidably connected to the folding foot push block 202 through the slide rail 209 and the slider 208. The output end of the lower cylinder 205 rises to hold the fixing plate 204 in place, thereby achieving a limiting function. The folding foot cylinder 201 drives the folding foot push block 202 to move horizontally.

[0030] It should be noted that the front of the frame 300 is equipped with a control unit that controls multiple cylinders.

[0031] In this embodiment, the frame cylinder 304 is installed on the top plate 303, the cooling fan 302 is installed on the back of the frame 300, and the air vent is located at the bottom of the body 301 in the direction of the control element.

[0032] In this embodiment, the slide rail fixing plate 204 is provided with a push block clearance groove 207, which is provided in the through groove of the slide rail fixing plate 204, allowing the folding foot push block 202 to move horizontally, and the folding foot push block 202 is placed in the push block clearance groove 207.

[0033] In this embodiment, the folding foot cylinder 201 is fixed to the side of the slide rail fixing plate 204, and the piston rod is connected to the folding foot push block 202.

[0034] The working principle of the above embodiments is as follows:

[0035] First, place the hardware-plastic shell assembly into the positioning groove of the fixed base 203. Then, start the switch and start the frame cylinder 304 to extend the piston rod, driving the upper mold device 100 to move down as a whole. The pressing teeth 103 of the hardware pressing device 102 are embedded in the gap of the workpiece foot position, resisting the lateral thrust of the folding foot push block 202. After the upper mold presses the workpiece, the piston rod of the lower push cylinder 205 extends, and the piston rod passes through the base plate 206, pressing against the slide rail fixing plate 204 to the preset height. The slide rail fixing plate 204 provides a rigid guide rail base for the folding foot push block 202, eliminating the vibration caused by the bending reaction force. The piston rod of the folding foot cylinder 201 extends, pushing the folding foot push block 202 to move horizontally forward along the slide rail 209. The front end of the push block bends and protrudes to press against the hardware foot position. The slide rail 209 and the slider 208 form a high-precision linear guide pair. The push block clearance groove 207 provides interference-free movement space.
