Description

Technical Field

[0001] The present invention belongs to the technical field of welding devices and welding methods, and particularly relates to a fully automatic front and back mesh welding and stacking device and a method for welding and stacking meshes with this device. Background Art

[0002] For meshes with the horizontal wires on the same side of the vertical wires, during stacking and transportation, in order to reduce the height, generally the meshes are placed with the horizontal wire sides facing each other. In this way, for meshes of the same number of layers, the stacking height of the meshes is reduced, the space occupied is small, and the transportation cost is greatly reduced. To place the meshes facing each other, mainly the following two methods are adopted: First, the method of manual flipping is used, where half of the welded and cut meshes are manually flipped to place the meshes facing each other. This method has low production efficiency, high labor intensity, is prone to injury during the production process, has poor safety performance, and also occupies a large space; Second, an additional mesh flipping mechanism needs to be set up behind the welding and stretching mechanism to flip half of the meshes through the mesh flipping mechanism to place the meshes facing each other. Although this method reduces the labor intensity and improves the safety, the equipment cost is high and the space occupied is large. Summary of the Invention

[0008] To solve the above problems, the technical solution adopted by the method for welding and stacking wire meshes using the above-mentioned fully automatic front and back side wire mesh welding and stacking device in the present invention is as follows:

[0009] The first step is to weld the wire mesh with the horizontal wires above the vertical wires

[0010] Step (1): Feeding the vertical wires

[0011] The ejector rod of the vertical wire lifting cylinder retracts, so that the bottom surface of the vertical wire threading pipe is slightly higher than the upper surface of the lower welding head, and the vertical wire feeding mechanism feeds the vertical wires forward.

[0012] Step (2): Feeding the horizontal wires

[0013] The horizontal wire lifting cylinder jacks up, moving the horizontal wire feeding frame body upward along the vertical slideway, making the horizontal wire inlet opposite to the upper horizontal wire limiting channel. The horizontal wire feeding mechanism sends the horizontal wires into the upper horizontal wire limiting channel through the horizontal wire inlet, and cuts the horizontal wires through the horizontal wire shearing mechanism.

[0014] Step (3): Pushing the horizontal wires onto the positioning calipers

[0015] Push the horizontal wires located in the upper horizontal wire limiting channel onto the positioning calipers through the upper horizontal wire pushing mechanism.

[0016] Step (4): Welding

[0017] The upper welding head of the welding mechanism presses down to weld the vertical wires and the horizontal wires together.

[0018] Step (5): Repeat the above steps until the wire mesh with the horizontal wires above the vertical wires is welded.

[0019] The vertical wire feeding mechanism continues to feed the vertical wires forward. From step (2) of feeding the horizontal wires to step (4) of welding, until the welding of the entire wire mesh is completed, and then enter the next step.

[0020] The second step is that the wire mesh reaches the net dropping platform

[0021] The welded wire mesh with the horizontal wires above the vertical wires reaches above the net dropping platform.

[0022] The third step is net dropping

[0023] Cut the wire mesh, open the net dropping mechanism of the net dropping platform, and the wire mesh with the horizontal wires above the vertical wires horizontally falls on the wire rack.

[0024] The fourth step is to weld the wire mesh with the horizontal wires below the vertical wires

[0025] Step (1): Feeding the vertical wires

[0026] The ejector rod of the vertical wire lifting cylinder pushes upward, so that the bottom surface of the vertical wire threading pipe is at least the height of the horizontal wire diameter higher than the upper surface of the lower welding head, and the vertical wire feeding mechanism feeds the wire forward.

[0027] Step (Two), feeding the horizontal wire

[0028] The horizontal wire lifting cylinder retracts, moving the horizontal wire feeding frame body downward along the vertical slideway, so that the horizontal wire inlet is opposite to the lower horizontal wire limiting channel, and the horizontal wire feeding mechanism feeds the horizontal wire into the lower horizontal wire limiting channel through the horizontal wire inlet.

[0029] Step (Three), pushing the horizontal wire onto the positioning caliper

[0030] The horizontal wire located in the lower horizontal wire limiting channel is pushed onto the positioning caliper by the lower horizontal wire pushing mechanism.

[0031] Step (Four), welding

[0032] The upper welding head of the welding mechanism presses down to weld the vertical wire and the horizontal wire together.

[0033] Step (Five), repeat the above steps until the welding of the mesh with the horizontal wire below the vertical wire is completed.

[0034] The vertical wire feeding mechanism continues to feed the wire forward, from step (Two) of feeding the horizontal wire to step (Four) of welding, until the welding of the entire mesh is completed, and then proceed to the next step.

[0035] Step Five, the mesh reaches the net dropping platform

[0036] The mesh with the horizontal wire below the vertical wire after welding reaches above the net dropping platform.

[0037] Step Six, dropping the net

[0038] Cut the mesh, open the net dropping mechanism of the net dropping platform, and the mesh with the horizontal wire below the vertical wire horizontally falls on the grid frame.

[0039] Step Seven, repeat steps one to six until the stacking height of the mesh reaches the requirement, move away the stacked mesh frame, and start stacking again until the welding is completed.

[0040] The method of welding and stacking wire meshes by the fully automatic front and back wire mesh welding and stacking device provided by the present invention has the following advantages compared with the prior art: First, since it includes a longitudinal wire feeding mechanism, a transverse wire feeding mechanism, a welding mechanism, a wire cutting mechanism, and a wire dropping platform with a wire dropping mechanism, the longitudinal wire feeding mechanism includes a longitudinal wire unwinding reel, a longitudinal wire straightening mechanism, a longitudinal wire feeding frame, a longitudinal wire threading tube, and a transverse wire cutting mechanism.

A clamping groove along the vertical slideway is arranged on the transverse wire feeding frame body. A transverse wire lifting cylinder is arranged below the transverse wire feeding frame body. The transverse wire feeding frame body is connected to the transverse wire feeding base through the transverse wire lifting cylinder.

The longitudinal wire feeding mechanism feeds the wire forward. The transverse wire lifting cylinder jacks up, moving the transverse wire feeding frame body upward along the vertical slideway, making the transverse wire inlet opposite to the upper transverse wire limiting channel. The transverse wire feeding mechanism sends the transverse wire into the upper transverse wire limiting channel through the transverse wire inlet, and cuts the transverse wire through the transverse wire cutting mechanism. Push the transverse wire located in the upper transverse wire limiting channel to the positioning caliper through the upper transverse wire pushing mechanism. The upper welding head of the welding mechanism presses down to weld the longitudinal wire and the transverse wire together. Repeat the above steps until the wire mesh with the transverse wire above the longitudinal wire is welded, and enter the next step.

A connecting spring 86 is used between the upper cover 65 and the lower cover 85.

[0055] The transverse wire feeding mechanism 2 is located on the side of the upper transverse wire limiting channel 63 and the lower transverse wire limiting channel 83.

[0056] First, weld the mesh above the horizontal wire, and the push rod of the longitudinal wire lifting cylinder 16 retracts, so that the bottom surface of the longitudinal wire threading tube 14 is slightly higher than the upper surface of the lower welding head 34. The longitudinal wire feeding mechanism feeds the wire forward, and the horizontal wire lifting cylinder 232 is lifted, and the horizontal wire feeding frame 23 is moved up along the vertical slide 221, so that the horizontal wire inlet 25 is opposite to the upper horizontal wire limiting channel 63, and the horizontal wire feeding mechanism 2 sends the horizontal wire to the upper horizontal wire limiting channel 63 through the horizontal wire inlet 25; the horizontal wire located in the upper horizontal wire limiting channel 63 is pushed onto the positioning caliper 36 through the upper horizontal wire pushing mechanism 7; the upper welding head 35 of the welding mechanism 3 is pressed down to weld the longitudinal wire and the horizontal wire together.

There is a lower wire pushing cylinder 93, which is movably connected to a lower wire pushing frame 92. A lower lifting cylinder 94 is provided above the lower wire pushing frame. When it is necessary to push the upper horizontal wire, the upper lifting cylinder pushes downward while the upper wire pushing cylinder pushes forward, and the upper horizontal wire is pushed onto the positioning caliper.

[0061] The first step is to weld the mesh with the horizontal wires above the vertical wires.

[0062] Step 1: Longitudinal wire feeding

[0064] Step (2): Horizontal wire feeding

[0066] Step (3): Push the horizontal wire onto the positioning caliper

[0067] The upper horizontal wire pushing mechanism 7 pushes the horizontal wire in the upper horizontal wire limiting channel 63 onto the positioning caliper 36;

[0068] Step 4: Welding

[0070] Step (5), repeat the above steps until the welding of the mesh with the horizontal wires above the vertical wires is completed.

[0071] The vertical wire feeding mechanism 1 continues to feed the vertical wires forward, from the horizontal wire feeding in step (2) to the welding in step (4), until the welding of the entire mesh is completed, and then proceed to the next step.

[0072] Step 2, the mesh reaches the net dropping platform.

[0073] The welded mesh with the horizontal wires above the vertical wires reaches above the net dropping platform 5.

[0074] Step 3, drop the net.

[0075] Cut the mesh, open the net dropping mechanism 51 of the net dropping platform 5, and the mesh with the horizontal wires above the vertical wires horizontally lands on the grid frame.

[0076] Step 4, weld the mesh with the horizontal wires below the vertical wires.

[0077] Step (1), feed the vertical wires.

[0078] The ejector rod of the vertical wire lifting cylinder 16 pushes upwards, making the bottom surface of the vertical wire threading pipe 14 at least the height of the horizontal wire diameter higher than the upper surface of the lower welding head, and the vertical wire feeding mechanism 1 feeds the vertical wires forward.

[0079] Step (2), feed the horizontal wires.

[0080] The horizontal wire lifting cylinder 232 retracts, moves the horizontal wire feeding frame body 23 downward along the vertical slideway 221, making the horizontal wire inlet 25 opposite to the lower horizontal wire limiting channel 83, and the horizontal wire feeding mechanism 2 feeds the horizontal wires into the lower horizontal wire limiting channel 83 through the horizontal wire inlet 25.

[0081] Step (3), push the horizontal wires onto the positioning caliper.

[0082] Push the horizontal wires located in the lower horizontal wire limiting channel 93 onto the positioning caliper 36 through the lower horizontal wire pushing mechanism 9.

[0083] Step (4), weld.

[0084] The upper welding head 35 of the welding mechanism 3 presses downwards to weld the vertical wires and the horizontal wires together.

[0085] Step (5), repeat the above steps until the welding of the mesh with the horizontal wires below the vertical wires is completed.

[0086] The vertical wire feeding mechanism 1 continues to feed the vertical wires forward, from the horizontal wire feeding in step (2) to the welding in step (4), until the welding of the entire mesh is completed, and then proceed to the next step.

[0087] Step 5, the mesh reaches the net dropping platform.

[0088] The welded horizontal wires are below the vertical wires, and the mesh sheet reaches above the net-laying platform 5;

[0089] Step 6, net-laying

[0090] Cut the mesh sheet, open the net-laying mechanism 51 of the net-laying platform 5, and the mesh sheet with horizontal wires below the vertical wires horizontally falls on the grid frame;

[0091] Step 7, repeat steps 1 to 6 until the stacking height of the mesh sheets reaches the requirement, move away the stacked mesh sheet rack, and start stacking again until welding is completed.

The vertical wire feeding mechanism feeds the wire forward. The second step, feeding the horizontal wire The horizontal wire lifting cylinder jacks up, moving the horizontal wire feeding frame body upward along the vertical slideway, making the horizontal wire inlet opposite to the upper horizontal wire limiting channel. The horizontal wire feeding mechanism sends the horizontal wire into the upper horizontal wire limiting channel through the horizontal wire inlet, and cuts the horizontal wire through the horizontal wire shearing mechanism. Step (3), pushing the horizontal wire onto the positioning caliper The horizontal wire in the upper horizontal wire limiting channel is pushed onto the positioning caliper by the upper horizontal wire pushing mechanism. Step (4), welding The upper welding head of the welding mechanism presses down to weld the vertical wire and the horizontal wire together. Step (5), repeat the above steps until the welding of the wire mesh with the horizontal wire above the vertical wire is completed The vertical wire feeding mechanism continues to feed the wire forward. From step (2) of feeding the horizontal wire to step (4) of welding, until the welding of the entire wire mesh is completed, and then enter the next step. Step 2, the wire mesh reaches the net dropping platform The welded wire mesh with the horizontal wire above the vertical wire reaches above the net dropping platform. Step 3, net dropping Cut the wire mesh, open the net dropping mechanism of the net dropping platform, and the wire mesh with the horizontal wire above the vertical wire horizontally falls onto the wire rack. Step 4, welding the wire mesh with the horizontal wire below the vertical wire Step (1), feeding the vertical wire The ejector rod of the vertical wire lifting cylinder jacks up, making the bottom surface of the vertical wire threading pipe at least the height of the horizontal wire diameter higher than the upper surface of the lower welding head. The vertical wire feeding mechanism feeds the wire forward. Step (2), feeding the horizontal wire The horizontal wire lifting cylinder retracts, moving the horizontal wire feeding frame body downward along the vertical slideway, making the horizontal wire inlet opposite to the lower horizontal wire limiting channel. The horizontal wire feeding mechanism sends the horizontal wire into the lower horizontal wire limiting channel through the horizontal wire inlet. Step (3), pushing the horizontal wire onto the positioning caliper The horizontal wire in the lower horizontal wire limiting channel is pushed onto the positioning caliper by the lower horizontal wire pushing mechanism. Step (4), welding The upper welding head of the welding mechanism presses down to weld the vertical wire and the horizontal wire together. Step (5), repeat the above steps until the welding of the wire mesh with the horizontal wire below the vertical wire is completed The vertical wire feeding mechanism continues to feed the wire forward. From step (2) of feeding the horizontal wire to step (4) of welding, until the welding of the entire wire mesh is completed, and then enter the next step. Step 5, the wire mesh reaches the net dropping platform The welded wire mesh with the horizontal wire below the vertical wire reaches above the net dropping platform. Step 6, net dropping Cut the wire mesh, open the net dropping mechanism of the net dropping platform, and the wire mesh with the horizontal wire below the vertical wire horizontally falls onto the wire rack.
