More importantly, the slag baffle is connected with the automatic lifting mechanism in a lever mode, a welding button of the flash welding machine synchronously controls the automatic lifting mechanism to ascend and descend, and then the slag baffle is synchronously controlled to ascend and descend, so that the slag baffle is located on the inner side of the chain ring body to be welded in the flash welding process, and the flash welding efficiency is improved. And after welding is finished, the slag baffle leaves the inner side of the chain ring body to be welded. In this way, the slag stopping requirement can be met, the slag stopping plate does not affect smooth proceeding of the follow-up chain ring manufacturing procedure, and the using time of the slag stopping plate is accurately controlled.

Description

Technical Field

[0001] The invention relates to the technical field of chain link welding equipment, and in particular to an automatic slag blocking device for flash welding chain links. Background Art

[0002] Flash welding is a welding equipment commonly used in the chain link manufacturing industry. During the flash welding process, sparks will be generated, affecting the safety production and environment on site. In order to prevent the adverse effects of spark splashing, baffles are usually added around the flash welder. On the one hand, it can prevent the welding slag from splashing onto the operator and causing safety hazards. On the other hand, it can also prevent the welding slag from splashing onto other equipment and causing adverse effects on the welding machine.

[0003] However, the added baffle can only reduce the impact of the splashing welding slag on personnel and machinery and equipment, but cannot effectively block the splashing welding slag on the anchor chain, especially it cannot prevent the welding slag from splashing to the inside of the chain link. If the welding slag is attached to the inside of the chain link, it will be pressed into the space between the crosspiece and the ring body during the subsequent pressing process, causing the crosspiece and the ring body to not fit tightly due to the inclusion of welding slag, resulting in the crosspiece loosening problem in the later stage.

[0004] At present, it is generally necessary to manually use a semi-arc hook to block the spatter slag generated during flash welding from being sprayed onto the inner side of the chain link. If the semi-arc hook is made of an insulator, its durability is poor; if it is made of a diamagnetic metal material, it is easy to cause sticking or burning of the weld body due to its conductivity when it is hung on the weld body. At the same time, this method of relying on manual hooking not only increases the workload of operators and affects production efficiency, but also has a certain impact on product quality. Summary of the invention

[0005] In order to solve the defects and shortcomings in the above-mentioned prior art, the present invention proposes an automatic slag blocking device for flash welding chain links, which has a simple structure, is economical and practical, convenient and efficient, and can effectively improve production efficiency and reduce labor intensity.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is: an automatic slag blocking device for flash welding chain links, comprising a slag blocking plate, which can move inside the chain link body to be welded and is not in contact with or connected to the chain link. When the chain link welding starts, the slag blocking plate is located inside the chain link body to be welded, separating the weld from the chain link on the opposite side. When the chain link is not welded or the welding is completed, the slag blocking plate leaves the inside of the chain link body to be welded and moves to an area that does not affect the chain link blank entering the welding position of the welding machine and being removed therefrom.

[0007] Furthermore, the automatic slag blocking device of the flash welding machine also includes a lever and an automatic lifting mechanism, one end of the lever is connected to the slag blocking plate, and the other end of the lever is connected to the automatic lifting mechanism, and the automatic lifting mechanism controls the lifting and lowering of the slag blocking plate through the lever; when the chain link welding starts, the automatic lifting mechanism controls the slag blocking plate to descend so that the slag blocking plate is located inside the chain link body to be welded; when the chain link is not welded or the welding is completed, the automatic lifting mechanism controls the slag blocking plate to rise so that the slag blocking plate leaves the inside of the chain link body to be welded.

[0008] Furthermore, the support shaft of the lever is fixed on the body of the flash welding machine.

[0009] Furthermore, the automatic lifting mechanism is an electric hydraulic cylinder, and the lever is connected to the piston rod of the electric hydraulic cylinder through a connecting rod. When the electric hydraulic cylinder is energized, the piston rod of the electric hydraulic cylinder rises and the slag baffle plate descends; when the electric hydraulic cylinder is de-energized, the piston rod of the electric hydraulic cylinder resets and the slag baffle plate rises.

[0010] Furthermore, the working state of the flash welder can simultaneously control the working state of the electric hydraulic cylinder. When the electrode of the flash welder is energized for welding, the electric hydraulic cylinder is in a energized state; when the electrode of the flash welder is not energized, the electric hydraulic cylinder is in a de-energized state.

[0011] Furthermore, the connecting rod includes connecting rod 1 and connecting rod 2, and the lever and connecting rod 1, connecting rod 1 and connecting rod 2, and connecting rod 2 and piston rod are all connected through a rotating pair.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. During the flash welding process of the chain link, a slag blocking plate is set on the inner side of the chain link to effectively block the welding slag ejected from the welding, preventing the welding slag from adhering to the inner side of the chain link, and preventing the welding slag from being pressed into the space between the crosspiece and the ring body in the subsequent pressing process, so as to avoid the crosspiece and the ring body from being unable to fit tightly due to the inclusion of welding slag, resulting in the crosspiece becoming loose after a period of use.

[0014] 2. Placing the slag stopper plate on the inner side of the chain ring through a lever can not only achieve the slag stopper effect, but also avoid the contact between the slag stopper plate and the chain ring and other equipment. It is no longer required that the material of the slag stopper plate be an insulating material, which reduces the material requirements for the slag stopper plate.

[0015] 3. With the use of the automatic lifting mechanism, the lifting and lowering of the slag blocking plate can be conveniently controlled with the help of a lever. When the chain link welding starts and the inner side of the chain link needs to be blocked, the slag blocking plate descends to the inner side of the chain link to achieve the slag blocking function; when the chain link welding is completed and the slag blocking is not needed, the slag blocking plate rises without affecting the placement, alignment and removal of the chain link. The slag blocking plate can play its slag blocking function only when needed, without affecting other production links of the chain link, and well controlling the use time of the slag blocking plate.

[0016] 4. The working state of the automatic lifting mechanism is linked with the working state of the welding machine, which can further realize the automation of the use process of the slag stopper, and no longer need to use manpower to control the position of the slag stopper, so as to achieve the effect of slag stopper and welding at the same time. At the same time, after welding is completed, the slag stopper automatically rises, and does not affect other links of chain link production.

[0017] 5. The slag blocking device is simple in design and does not require large-scale modification of the flash welding equipment. Only levers and automatic lifts need to be added to the existing flash welding equipment to achieve the automatic slag blocking function on the inner side of the chain ring. The equipment modification and subsequent maintenance costs are low. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the use of words such as "exemplary", "for example" or "for example" is intended to present related concepts in a specific way.

[0026] like Figure 1-2 As shown, an automatic slag blocking device for a flash welding chain link of the present invention comprises a slag blocking plate 1, a slag blocking plate lever 2, a lever support shaft 3, a connecting rod 1 4, a connecting rod 2 5, an electric hydraulic cylinder assembly 6, a rotating pair 1 7, a rotating pair 2 8, and a rotating pair 3 9. The slag blocking plate 1 can move inside the chain link body to be welded. The slag blocking plate 1 is connected to one end of the slag blocking plate lever 2, the lever support shaft 3 of the slag blocking plate lever 2 is fixed on the flash welding machine, and the other end of the lever 2 is connected to the electric hydraulic cylinder assembly 6 through the connecting rod 1 4 and the connecting rod 2 5.

[0027] The other end of the slag baffle plate lever 2 is connected to the electric hydraulic cylinder assembly 6 in a connection manner that the other end of the lever 2 is connected to the connecting rod 1 4 through a rotating pair 1 7, the connecting rod 1 4 is connected to the connecting rod 2 5 through a rotating pair 2 8, and the connecting rod 2 5 is connected to the piston rod of the electric hydraulic cylinder assembly 6 through a rotating pair 3 9.

[0028] When the electric hydraulic cylinder assembly 6 is powered on, the piston rod of the electric hydraulic cylinder assembly 6 rises, and then drives the connecting rod 1 4 and the connecting rod 2 5, and under the action of the slag plate lever 2, the slag plate 1 is lowered to the inner side of the chain link body to be welded. When the electric hydraulic cylinder assembly 6 is powered off, the piston rod of the electric hydraulic cylinder assembly 6 is reset, and then drives the connecting rod 1 4 and the connecting rod 2 5, and under the action of the slag plate lever 2, the slag plate 1 is raised to leave the inner side of the chain link body to be welded.

[0029] Further, the welding start button of the flash welder can control the power-on state of the electric hydraulic cylinder assembly 6. When the welding start button of the flash welder is turned on, the electrode of the flash welder is powered on and starts to weld the chain link, and the electric hydraulic cylinder assembly 6 is in the power-on state; when the welding start button of the flash welder is turned off, the electrode of the flash welder is powered off and stops welding the chain link, and the electric hydraulic cylinder assembly 6 is in the power-off state.

[0030] By controlling the welding start button of the flash welder, the piston rod lifting state of the electric hydraulic cylinder assembly 6 can be synchronously realized, and then the lifting and lowering control of the slag stopper plate 1 can be synchronously realized. When the chain link welding starts, the slag stopper plate 1 will be located inside the chain link body to be welded, separating the weld from the chain link on the opposite side, thereby realizing the slag blocking function on the inside of the chain link; when the chain link welding is completed, the slag stopper plate 1 will leave the inside of the chain link body to be welded. After the slag stopper plate 1 is raised, sufficient space can be reserved for the subsequent processes and other operations of the chain link, thereby not affecting the assembly and docking of the two butt-welding end faces of the chain link blank before the chain link welding, and the removal of the chain link.

[0031] The above contents are further detailed descriptions of the present invention in combination with specific / preferred implementations, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can also make several substitutions or modifications to these described embodiments without departing from the concept of the present invention, and these substitutions or modifications should be regarded as belonging to the protection scope of the present invention.
