Description

Automatic chaining and welding integrated machine for anti-skid chains and chain processing method

Technical Field

The invention belongs to the technical field of chain processing, and particularly relates to an automatic chaining and welding integrated machine for an anti-skid chain.

Background

The chain is formed by a chain of chain links which are buckled one by one to form a chain link of strip metal. It is used for mechanical transmission and traction. The chain is divided into a transmission chain; a conveyor chain; pulling the chain; special professional chains, etc. The invention mainly focuses on the large chain knitting manufacturing process.

Chain forming is divided into chain knitting and chain welding, and the chain knitting process procedures are roughly divided into straightening, automatic intermittent feeding, cutting, bending and automatic connection; the chain welding can be divided into the procedures of wiring, straightening, pressing, welding, rough edges and the like.

At present, the main modes for the chain knitting process are as follows: the first semi-automatic chain knitting, straightening and cutting process is completed in advance, and workers complete intermittent feeding, control the punch of the chain knitting machine to move up and down to complete chain bending and complete one-by-one connection. The labor intensity is high, the danger degree is high, the automation degree is low, the equipment integration degree is low, and the method is not suitable for a modern processing mode any more. The second cam transmission type chaining machine can complete the chain knitting process, but the equipment is driven by a pure mechanical type, so that the size is large, the transmission process is complex, and the noise generated by the impact of the cam transmission on the core rod is large. When chains of different models are produced, the whole set of forming mechanism is replaced, and the time cost is huge.

At present, the welding process of the chain mainly comprises the following steps: the first semi-automatic chain welding mode is high in labor intensity, low in automation degree and low in efficiency, and large sparks caused by welding cause certain damage to personnel; the second large-scale mechanical transmission type chaining machine adopts transmission modes such as gear and cam, is large in size, needs to be maintained and repaired regularly in severe working occasions in a workshop, and is time-consuming and high in maintenance cost.

Therefore, the design of a novel chain knitting and welding integrated machine which can complete the chain knitting and welding process and overcome the defects of the traditional chain knitting and welding machine is an urgent need for the development of the chain processing field in China.

The invention has the beneficial effects that:

1. the power source for realizing the required functional action adopts a hydraulic and pneumatic mode, the defects of pure mechanical transmission, large volume, complex transmission process and complex maintenance of the traditional chaining machine equipment are overcome, the production noise is reduced, the equipment vibration is reduced, and a better working environment is provided for workers.

2. The invention adopts a mode of two procedures of cutting and forming, the length of the wire rod is controlled by the feeding mechanism, and the wire rod processing of different sizes is realized by only replacing the core rod required by bending forming. Different from the traditional material cutting and forming, the whole set of forming mechanism needs to be replaced when wires with different sizes are processed. Saving mass production time and equipment cost. Is more suitable for unmanned production of production lines.

3. The invention realizes the bending and forming of the wire rod by adopting a hydraulic bending mode. For the traditional chain knitting machine, a cam rotation and cutting and forming integrated mode is adopted, the impact force required by cutting is huge, particularly for a large chain, the cutting and forming integrated mode has huge impact on a mandrel, so that the mandrel is replaced normally, the production cost is improved, and the production efficiency is reduced. The additional impact causes the link itself to be defective at the bend, reducing the chain quality. The hydraulic mode of the invention realizes adjustable pressure for wires with different diameters, and the two procedures of cutting and forming avoid overlarge impact on the core rod, avoid damage to the chain link, reduce the cost and improve the production efficiency.

4. The invention realizes one-step molding of the chain link by designing the molding mechanism. Because the wires are not bent safely at the primary bending joint, the wires need to be formed secondarily. The gear rotates to adjust the angle of the chain links for connection, meanwhile, the chain links enter the vertical groove of the forming sliding block, complete bending forming of the chain links is achieved when the next chain link is bent at one time, and one-time forming of the chain links by the same bending forming mechanism is achieved indirectly.

5. The invention adopts the servo motor to control the wire rod conveying drive, replaces a connecting rod mechanism and accurately controls the wire rod conveying length.

6. The invention adopts the crevasse device, and has the characteristic of larger cutting force required by the large-diameter wire rod, and simultaneously has the positioning function, so that the cutting device can accurately cut the wire rod according to the crevasse position in the cutting process, and the phenomenon of wire rod deviation possibly caused by one-time cutting is avoided.

7. According to the invention, the adopted coil chain servo motor is matched with the triangular chuck and the fixed pulley to realize the routing control of the chain, and the welding of different sizes is realized by controlling the rotating angle. In addition, through the idle running of the control servo motor, compared with the traditional cam claw routing mode, the speed is higher, the function of controlling and skipping chain rings which do not need to be welded is achieved, and the follow-up chain ring picking is more convenient.

8. In the deburring mechanism, the position of the deburring cutter fixed on the cutter holder is asymmetric, certain dislocation exists, two times of semi-annular welding scraps fall off in the one-time deburring process of annular burrs, and the phenomenon that the traditional equipment is used for performing two times of deburring processes or a burr ring is still sleeved on a chain ring is avoided.
