Technical Field

[0001] The utility model relates to the technical field of automobile component processing equipment, in particular to a bending machine for processing carriage railings. Background Art

[0002] The railings of a carriage are usually plate-like structures made of metal materials (such as light steel, stainless steel, steel, aluminum, etc.). They are mainly used to fix or separate different types of goods to prevent the goods from moving, rolling or colliding with each other during transportation, thereby protecting the goods from damage.

[0003] The production process of railings often involves the use of a bending machine, which creates a corrugated shape. This corrugated design, through a change in physical structure, enhances the overall strength and impact resistance of the railings. Compared to flat railings, corrugated railings are better able to disperse and absorb impact forces, thereby protecting the carriage and cargo. This design principle is similar to that of corrugated guardrails, which utilize a wavy structure to enhance impact resistance.

[0004] In the prior art, in order to process a plate-like structure into a corrugated shape, the steel plate is basically placed manually on a bottom mold, and then the steel plate can be bent by the upper mold and the bottom mold, and then the steel plate is turned over and the above operations are repeated to process the steel plate into a corrugated shape. Although the above method can complete the processing of the car railing, the processing efficiency is slow. If the steel plate can be processed into a corrugated shape at one time, the efficiency of the car railing processing can be greatly improved. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-3 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0024] like Figure 1 、 2 3: It includes a die 100, which has a plurality of pits arranged linearly on the die 100. A connecting block 200 is further provided above the die 100. The connecting block 200 is set as a square structure in this embodiment, and a plurality of groups of chutes 201 are vertically provided on the connecting block 200. The bottom of the chutes 201 is connected to the bottom of the connecting block 200. The number of each group of chutes 201 is consistent with the number of pits, and each group of chutes 201 is located above the pits. A slide rod 202 is also provided in the slide groove 201, and the slide rod 202 can slide up and down in the slide groove 201. A punch 203 is also provided at the bottom of the slide rod 202, so that the slide rod 202 can drive the punch 203 to move up and down. The punch 203 moves into the pit on the die 100 to complete the bending of the steel plate, and a driving mechanism 300 is provided on the connecting block 200 corresponding to the multiple slide rods 202. The driving mechanism 300 is used to drive the multiple slide rods 202 to move downward successively.

[0025] When the carriage railing is bent, the steel plate is placed on the upper surface of the die 100, and then the driving mechanism 300 can indirectly drive multiple groups of slide rods 202 to move downward successively. The downward movement of each group of slide rods 202 can drive the punch 203 to move downward. The downward movement of the punch 203 can push a part of the steel plate into the die 100, thereby bending the steel plate. Moreover, since the steel plate is partially pushed into the die 100, the steel plate body will be deformed, so that the two adjacent punches 203 will not affect the steel plate when they move downward successively. Therefore, after multiple punches 203 move downward, the steel plate can be stamped and bent to form a wavy carriage railing.

[0026] like Figure 2 、 3 As shown,

[0027] The driving mechanism 300 includes a movable hole 301 arranged horizontally on the connecting block 200. The movable hole 301 is located above the multiple groups of slide grooves 201 and is connected to the top of the multiple groups of slide grooves 201. When the slide rod 202 slides up and down in the slide groove 201, the top of the slide rod 202 will also move into the movable hole 301. A movable rod 302 is also slidably provided in the movable hole 301. The movable rod 302 can slide back and forth in the movable hole 301. The movable rod 302 is connected to an external driving member. The driving member can be set as an electric push rod or a pneumatic push rod to facilitate driving the movable rod 302 to slide back and forth in the movable hole 301. The movable rod 302 is also provided with a first inclined surface 303 at one end close to the connecting block 200. The first inclined surface The surface 303 is located on one end of the movable rod 302 close to the connecting block 200, and the first inclined surface 303 is arranged toward the sliding rod 202. Corresponding to the first inclined surface 303, a second inclined surface 304 is further provided at the end of the sliding rod 202. The second inclined surface 304 is located on one end of the sliding rod 202 close to the movable hole 301, and the second inclined surface 304 is arranged toward the movable plate. At the same time, the angles between the first inclined surface 303 and the second inclined surface 304 on the movable rod 302 or the sliding rod 202 are both 45 degrees, so that the first inclined surface 303 can fit with the second inclined surface 304 during the movement of the movable rod 302, and then the movable rod 302 can successively move down during the movement of the movable rod 302.

[0028] That is, the driving member on the driving mechanism 300 drives the movable rod 302 to move toward the movable hole 301. During the movement of the movable rod 302, the first inclined surface 303 can successively contact the second inclined surface 304 of the slide bar 202. When the first inclined surface 303 contacts the second inclined surface 304, the slide bar 202 can be driven downward in the slide groove 201 by friction. The downward movement of the slide bar 202 can drive the punch 203 to move downward to bend the steel plate, and when the movable rod 302 continues to move in the movable hole 301, the first inclined surface 303 on the movable rod 302 can contact the next second inclined surface 304, and then the movable rod 302 slides in the movable hole 301, which can successively cause multiple punches 203 to move downward to bend the steel plate.

[0029] like Figure 2 、 3 As shown,

[0030] The cross-sections of the movable rod 302 and the sliding rod 202 are both polygonal structures, and the cross-sections of the movable hole 301 and the sliding groove 201 are also polygonal structures, so that the movable rod 302 will not rotate during the sliding process in the movable hole 301, and the sliding rod 202 will not rotate during the sliding process in the sliding groove 201, thereby not affecting the movable rod 302 to indirectly drive the multiple groups of sliding rods 202 to move downward.

[0031] like Figure 2 、 3 As shown,

[0032] The connecting block 200 is also provided with multiple groups of storage grooves 204. The number of the multiple groups of storage grooves 204 is consistent with the number of the multiple groups of slide grooves 201. In this embodiment, the number of each group of storage grooves 204 or slide grooves 201 is two. Each storage groove 204 is located on the peripheral side of the slide groove 201. A positioning component 400 is provided in the storage groove 204 for driving the slide rod 202 to reset. That is, after the slide rod 202 moves downward, it can also be automatically reset by the positioning component 400, thereby facilitating the equipment to bend the steel plate again.

[0033] like Figure 2 、 3 As shown,

[0034] The positioning assembly 400 includes a snap ring 401 disposed transversely around the side of the slide bar 202. A plurality of telescopic rods 402 are vertically disposed within the storage slot 204. The ends of the telescopic rods 402 are connected to the snap ring 401. The telescopic rods 402 provide support to the slide bar 202 through the snap ring 401. A spring 403 is also sleeved on the telescopic rods 402 to guide the spring 403, preventing it from bending during extension. One end of the spring 403 is connected to the snap ring 401, while the other end is connected to the end of the storage slot 204. In other words, the spring 403 always pushes the end of the snap ring 401 away from the die 100. Consequently, after the movable rod 302 is reset, there is no external force exerting pressure on the slide bar 202. The spring 403, via the snap ring 401, can drive the slide bar 202 to reset, thereby indirectly driving the punch 203 to reset.

[0035] like Figure 2 、 3 As shown,

[0036] The second inclined surface 304 is further provided with a groove 305, and a plurality of rollers 306 are provided for rolling in the groove 305. In this embodiment, there are two rollers 306 and they can rotate in the groove 305, and the outer surface of the roller 306 can extend out of the groove 305, so that the first inclined surface 303 can contact the roller 306 when moving, so that the movable plate can be smoother when indirectly driving the slide rod 202 to move downward, and thus no jamming or sticking occurs.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
