Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a double-wire guardrail mesh resistance welding machine. Background Art

[0002] As we all know, double-wire guardrail mesh is mainly used as a guardrail. It is mainly produced by superimposing and welding a group of horizontal wires and two groups of longitudinal wires. During the production of existing double-wire guardrail mesh, it is usually welded by manually inserting horizontal and longitudinal wires. At the same time, the mesh needs to be turned over during manual threading to perform double-sided welding. When using this method, the production process is relatively complicated, the manual threading and welding work speed is slow, the efficiency is low, and more manpower is consumed. At the same time, the distribution uniformity of the weld points on the mesh is poor, the mesh welding is irregular, and the mesh strength is low, resulting in poor product quality.

[0003] In recent years, some manufacturers have launched automatic welding machines on the market, which feed two upper and lower longitudinal wires at the same time, and add a device for feeding horizontal wires to the welding machine, which shoots the horizontal wire into the middle of the two longitudinal wires and then welds. The equipment is relatively complex, and welding requires high instantaneous power and high power transformer capacity, which limits the promotion of the equipment. Summary of the invention

[0017] The main functions achieved by the present invention are: automatic wire feeding and welding processing are carried out through the double-wire guardrail mesh, which can effectively simplify its production method, improve the degree of automation, save manpower, and improve work efficiency. At the same time, the uniformity of the distribution of weld points on the mesh is improved, the aesthetics and strength of the mesh are improved, and the production quality of the mesh is effectively improved, and the practicality and reliability are improved.

[0018] The double-wire guardrail mesh resistance welding machine of the present invention, the welding mechanism 18 can be assembled from an upper beam device sealing plate, a pull rod, a spring, an adjusting rod, an adjusting pull rod sleeve, an upper electrode, a lower beam device I-beam, a dovetail plate, a lower electrode seat, a side plate, a main shaft, an eccentric sleeve, a clap, a transformer, a motor, a reducer, a bracket, a cam and a connecting rod.

[0019] The double-wire guardrail mesh resistance welding machine of the present invention, the automatic net dropping device 19 can be assembled from a net delivery hook, a net delivery hook track, two sets of trawl support plates and an automatic net dropping bracket.

[0020] The double-wire guardrail mesh resistance welding machine of the present invention has each set of trawl support plates controlled by two sets of cylinders to support and control the bottom.

[0021] In the double-wire fence mesh resistance welding machine of the present invention, the first longitudinal hopper 5, the transverse hopper 6 and the second longitudinal hopper 14 can all be assembled from a wire holding wheel, a wire blocking plate, a dovetail plate, a speed reducer and a stepping motor.

[0022] The double-wire guardrail mesh resistance welding machine of the present invention, the first net pulling trolley 9 and the second net pulling trolley 17 can be assembled from a net pulling hook, a cylinder, a dovetail plate, a servo motor, a reducer, a transmission shaft, a gear, a bearing wheel, a bracket, a track and a trawl frame.

[0024] The double-wire guardrail mesh resistance welding machine of the present invention has the following specific operation mode:

[0025] 1. The operator prepares the longitudinal and transverse wires of the required specifications for welding mesh in advance;

[0026] 2. Place the longitudinal and transverse threads in the corresponding hopper inside;

[0027] 3. Calculate the size according to the requirements of processing double-wire guardrail mesh, and then input the size data into the corresponding module through the touch screen of the equipment control system. After completing the parameter setting, operate the start button on the control system, select the automatic button, and then press the start button, the equipment can work normally;

[0028] 4. The first longitudinal hopper 5 drops the first layer of longitudinal wires in sequence, and the first longitudinal aligning wire feeding device 4 aligns the longitudinal wires of this layer and sends the first layer of longitudinal wires to the lower electrode of the left welding mechanism 18, and the aligned longitudinal wires stop at the falling position of the first horizontal wire;

[0029] 5. At this time, the horizontal wire automatically falls from the horizontal hopper 6, the left welding mechanism 18 automatically welds, and the net-pulling hook on the first net-pulling trolley 9 has automatically stopped at the position where the first horizontal wire falls;

[0030] 6. When the left welding mechanism 18 completes the first welding, the first mesh-pulling trolley 9 automatically clamps the first horizontal wire by controlling the mesh-pulling hook by the servo motor under the electrical control system. When the upper beam of the left welding mechanism 18 is lifted, the first mesh-pulling trolley 9 moves a grid distance of the horizontal wire spacing. When the left welding mechanism 18 completes the second grid welding, the first mesh-pulling trolley 9 moves the second grid distance again. According to the set parameters, welding and mesh pulling are carried out in sequence;

[0031] 7. When the first layer of longitudinal wires and transverse wires are all welded into semi-finished products, the first net-pulling trolley 9 delivers the semi-finished products to the set position, and the second longitudinal hopper 14 starts to drop the second layer of longitudinal wires in sequence and puts them at the corresponding longitudinal wire positioning positions;

[0032] 8. The second longitudinal wire feeding device 13 starts to work and sends the second layer of longitudinal wires together with the semi-finished mesh to the lower electrode of the right welding mechanism 18. At this time, the second mesh pulling trolley 17 is already waiting between the lower electrodes of the right welding mechanism 18;

[0033] 9. The right welding mechanism 18 automatically welds. After the first welding is completed, the mesh hook of the second mesh-pulling trolley 17 is automatically lifted to clamp the first horizontal wire. At this time, the upper beam of the right welding mechanism 18 is lifted, and the second mesh-pulling trolley 17 pulls the mesh. The mesh pulling distance is the same as the first mesh-pulling trolley 9;

[0034] 10. According to the requirements of the semi-finished product welding mesh, the right welding mechanism 18 and the second mesh pulling trolley 17 perform the same work;

[0035] 11. When the second net-pulling trolley 17 moves to a certain position, the net-transporting hook 20 automatically falls down to grab the net and delivers the net to the net-transporting hook 20. When the net is transported to a certain position, the electrical control system gives a signal to the solenoid valve, the cylinder on the support plate works, the support plate falls down and the net is dropped, completing the production of a double-wire guardrail net.

[0036] The double-wire guardrail mesh resistance welding machine of the present invention has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve its beneficial effects.

[0037] The above is only 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 technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
