Description

Technical Field

[0001] The present application relates to the field of steel grating welding equipment, and in particular to a steel rod feeding equipment for steel grating welding. Background Art

[0002] At present, steel grating welding is one of the common processes in modern industrial production, and is widely used in construction, transportation, chemical industry and other fields. In order to improve production efficiency and product quality, automatic feeding equipment has gradually become a research hotspot in this field. At present, there are many automatic feeding equipment for different application scenarios on the market. These equipment not only improve production efficiency, but also reduce the risk of manual operation, which greatly promotes the progress and development of the industry.

[0003] In practical applications, in order to solve the problem of accurate transportation of steel rods, the existing technical means mainly include manual pushing, pneumatic push rods and belt transmission. Although the manual pushing method is simple and easy, it is labor-intensive and difficult to achieve continuous operation; pneumatic push rods can achieve long-distance transportation, but there are deficiencies in precision control; belt transmission can better meet the requirements of short-distance high precision, but still requires a complex adjustment mechanism to ensure that the steel rods are accurately in place. In addition, some manufacturers have adopted a chain transmission system, which drives the rollers to rotate through the chain to achieve smooth transportation of steel rods.

[0004] However, there are still some problems with the above method in actual use. For example, after a long period of operation, manual push and pneumatic push rods are prone to inaccurate positioning, resulting in weld point offset, affecting product quality and stability. The maintenance cost of belt drive and chain transmission systems is high, and the adjustment time is long when switching between multiple stations, which reduces the overall production efficiency. Therefore, how to design a steel rod feeding equipment for steel grating welding that can ensure high-precision transportation and reduce maintenance costs has become a technical problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0027] The inventor of the present application discovered that the existing steel rod feeding equipment for steel grating welding has problems of low precision and high maintenance cost during the conveying and positioning processes. For this reason, the present application mainly adopts the following steel rod feeding equipment for steel grating welding, including: a bracket, a conveying device installed on the bracket, a positioning device arranged at the end of the conveying device, and a driving device, which achieves the effects of high-precision conveying and low maintenance cost. The present application is further described in detail below.

[0028] Example 1 The steel bar feeding equipment for steel grating welding provided in the embodiment of the present application comprises a bracket, a conveying device installed on the bracket, a positioning device arranged at the end of the conveying device, and a driving device. The conveying device is used to convey the steel bar along a predetermined path, the positioning device is used to accurately position the steel bar conveyed to the end, and the driving device is connected to the conveying device to drive the conveying device to move, thereby achieving the effect of high-precision conveying and low maintenance cost.

[0029] Specifically, the conveying device includes a plurality of rollers and chains, and the rollers are driven to rotate by the driving device through the chains. The rollers are made of wear-resistant materials, such as stainless steel or carbide, to extend the service life. The chains can be selected from standard industrial chains or special customized chains with higher durability. This design not only ensures the smooth conveying of the steel rods, but also effectively reduces the accumulation of errors caused by wear.

[0030] Specifically, the positioning device includes at least one pair of clamping claws with adjustable spacing, and the clamping claws can move in the horizontal direction to clamp or release the steel rod. One end of the clamping claw is fixed to the bracket, and the other end is provided with a spring, which is used to reset the clamping claw. The material of the clamping claw can be selected from high-strength aluminum alloy or steel to ensure sufficient rigidity and durability. In addition, the surface of the clamping claw can be covered with a layer of anti-slip rubber to increase friction and prevent the steel rod from slipping.

[0031] Specifically, the guide device is arranged on both sides of the conveying device to guide the steel rod to move along a predetermined path. The guide device includes two sets of parallel guide rails, and a gap is left between the guide rails for the steel rod to pass through. The guide rails can be made of stainless steel or aluminum alloy materials to resist corrosion and wear. The cross-sectional shape of the guide rail can be designed to be square, round or other special shapes according to actual needs to adapt to steel rods of different specifications.

[0032] Specifically, the driving device includes an electric motor and a gear box, and the electric motor is connected to the conveying device through the gear box. The electric motor can be a stepper motor, which can accurately control the speed and position of the conveying device. The function of the gear box is to convert the high-speed rotation of the electric motor into a low-speed and high-torque rotation suitable for the operation of the conveying device. Lubricating oil can be added inside the gear box to reduce friction between gears and improve transmission efficiency.

[0033] Specifically, the detection unit is installed near the positioning device to detect the position of the steel rod and generate a signal. The detection unit can use a photoelectric switch, which can send an electrical signal when the steel rod reaches the specified position to notify the control system to perform the next operation. The selection of the photoelectric switch needs to consider its sensitivity and response speed to ensure that the position of the steel rod is detected in a timely and accurate manner.

[0034] The implementation principle of this embodiment is: by reasonably configuring the conveying device, positioning device, guiding device and driving device, high-precision conveying of steel rods is achieved. In particular, the combination of rollers and chains is used to enable the steel rods to maintain stable linear motion during the conveying process, avoiding the inaccurate positioning problems existing in traditional manual pushing and pneumatic push rod methods. At the same time, the design of the clamping claw increases the flexibility and reliability of the system, and can be quickly adjusted according to steel rods of different lengths and diameters. In addition, the application of photoelectric switches further improves the automation level and work efficiency of the system. In general, this embodiment significantly improves the reliability and production efficiency of the steel rod feeding equipment for steel grating welding, and reduces maintenance costs.

[0035] Embodiment 2 This embodiment is different from the above embodiment in that: Specifically, in addition to the roller and chain, the conveying device may also be provided with a buffer device. The buffer device is located at the front end of the conveying device and is used to absorb the impact energy generated when the steel rod enters the conveying device. The buffer device may be an elastic gasket or a flexible tube with a certain elasticity. This not only protects the roller and chain from damage, but also reduces noise and improves the comfort of the working environment.

[0036] Specifically, in addition to the clamping claws, the positioning device may also include a clamping mechanism. The clamping mechanism is disposed above the clamping claws and is used to press the steel rod downward while the clamping claws clamp the steel rod, to ensure that the steel rod does not jump or deviate during the clamping process. The clamping mechanism may be driven by a pneumatic cylinder or a hydraulic cylinder to provide stable pressure.

[0037] Specifically, in addition to the guide rail, the guide device can also be equipped with a set of auxiliary guide wheels. The auxiliary guide wheels are distributed on both sides of the guide rail, forming a closed space with the guide rail to better guide the steel rod along the predetermined path. The auxiliary guide wheels can also be made of wear-resistant materials, such as nylon or polyurethane, to reduce friction with the steel rod.

[0038] Specifically, in addition to the motor and gearbox, the drive device can also be equipped with a transmission. The transmission can adjust the power output of the motor, thereby achieving more precise speed control. This is very useful for occasions where the conveying speed needs to be changed frequently, and can greatly improve the scope of application of the equipment.

[0039] The implementation principle of this embodiment is: by adding a buffer device, a clamping mechanism, an auxiliary guide wheel and a transmission, the function and performance of the steel rod feeding equipment for steel grating welding are further optimized. The buffer device effectively reduces the impact when the steel rod enters the conveying device, extending the life of the equipment; the clamping mechanism ensures the stability of the steel rod during the clamping process and reduces the possibility of weld point deviation; the auxiliary guide wheel enhances the guiding ability of the guide device and ensures the accurate positioning of the steel rod; the transmission provides more flexible speed control options and expands the application scenarios of the equipment. In summary, this embodiment not only solves the problems existing in the prior art, but also greatly improves the overall performance and reliability of the equipment.

[0040] Embodiment 3 The difference between this embodiment and the above embodiment is that: Specifically, in addition to rollers and chains, the conveying device can also adopt a screw conveying method. The screw conveying device includes a screw shaft and blades arranged around the screw shaft. The screw shaft is driven to rotate by a driving device, driving the steel rod to move forward along the screw shaft. The advantage of screw conveying is that it can achieve long-distance continuous conveying, which is particularly suitable for production lines that require a large number of steel rods to be continuously supplied.

[0041] Specifically, in addition to the clamping claws, the positioning device can also be equipped with a visual recognition system. The visual recognition system is installed near the positioning device, and monitors the position of the steel rod in real time through a camera, and calculates the actual position of the steel rod through an image processing algorithm. The visual recognition system is connected to the control system. When it detects that the steel rod deviates from the predetermined position, the control system will automatically adjust the position of the clamping claw to ensure that the steel rod is accurately in place. This method can greatly improve the accuracy and reliability of positioning.

[0042] Specifically, in addition to the guide rail, the guide device can also add a magnetic levitation guide system. The magnetic levitation guide system uses the repulsive effect of the electromagnetic field to make the steel rod hover in the air and move forward through a specific path. The magnetic levitation guide system can reduce the friction between the steel rod and the guide rail, and improve the conveying speed and accuracy. In addition, since there is no physical contact, the maintenance cost is relatively low.

[0043] Specifically, in addition to the electric motor and gearbox, the drive device can also use a linear motor. The linear motor can directly drive the conveying device to move in a straight line without the need for intermediate transmission components, simplifying the structure and improving efficiency. The working principle of the linear motor is to directly generate thrust through the change of the electromagnetic field, making it very suitable for high-precision and high-speed conveying tasks.

[0044] The implementation principle of this embodiment is: by introducing spiral conveying, visual recognition system, magnetic levitation guide system and linear motor, the advancement and intelligence level of the steel rod feeding equipment for steel grating welding are further improved. The spiral conveying device enables the equipment to have stronger long-distance transportation capabilities to meet the needs of large-scale production; the combination of the visual recognition system and the intelligent control system realizes highly automated precise positioning, improves production efficiency and product quality; the magnetic levitation guide system and the linear motor jointly improve the operating speed and accuracy of the equipment and reduce maintenance costs. Overall, this embodiment shows the development trend of future high-end manufacturing equipment and brings new solutions and technological breakthroughs to the industry.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
