This embodiment provides a mesh reinforcement production facility that can be used to weld together warp and weft reinforcement to form a mesh reinforcement having a plurality of openings. As shown in fig. 1 and 2, the mesh reinforcement production apparatus includes a welding device 400, a blanking device 500, and a reinforcement bar positioning device 100. Wherein, doffer 500 mainly used realizes the transmission to the weft reinforcing bar to make the weft reinforcing bar can accurately slide to the warp reinforcing bar on. The reinforcing bar positioning device 100 is mainly used for realizing accurate positioning between weft reinforcing bars and warp reinforcing bars. The welding apparatus 400 is mainly used to weld the warp and weft reinforcements that are precisely positioned.
Specifically, as shown in fig. 1 and 2, the welding apparatus 400 includes an upper electrode 401 and a lower electrode 402 disposed above and below. Optionally, the upper electrode 401 is disposed directly above the lower electrode 402. The shape of the upper electrode 401 and the lower electrode 402 is preferably the same, in this embodiment, both the upper electrode 401 and the lower electrode 402 are square, but in other embodiments, the upper electrode 401 and the lower electrode 402 may also be circular, oval, or kidney-shaped. The upper electrode 401 and the lower electrode 402 are further connected with a power supply device (not shown in the figure), which can supply power to the upper electrode 401 and the lower electrode 402, so that the upper electrode 401 and the lower electrode 402 can weld warp steel bars and weft steel bars which are arranged between the upper electrode 401 and the lower electrode 402 in a crossed manner.
Because the length of the warp reinforcing steel bar is long, the warp reinforcing steel bar is generally placed between the upper electrode 401 and the lower electrode 402 during welding, and the weft reinforcing steel bar with short length is rolled onto the warp reinforcing steel bar by the blanking device 500. Of course, in other embodiments, the weft steel bars may be disposed between the upper electrode 401 and the lower electrode 402, and the warp steel bars may be rolled down from the blanking device 500 onto the weft steel bars. For convenience of description, the reinforcing bars located between the upper electrode 401 and the lower electrode 402 will be referred to as a first reinforcing bar 200, and the reinforcing bars rolled from the blanking device 500 will be referred to as a second reinforcing bar 300.
As shown in fig. 1 and 2, the blanking device 500 includes a blanking frame (not shown) and a blanking plate 501, and the blanking frame is used to fix the blanking device 500 on a base (not shown) of a mesh reinforcement production facility or other external equipment. Blanking plate 501 is convexly arranged on one side of blanking frame close to welding device 400, and blanking plate 501 is provided with a blanking inclined plane with a guiding function, so that second reinforcing steel bar 300 can smoothly slide down from the blanking inclined plane and fall onto first reinforcing steel bar 200. Under the action of inertia, the second reinforcing bar 300 can roll on the first reinforcing bar 200 in a first direction (the direction indicated by the arrow in fig. 1). In this embodiment, the first direction is parallel to the axial direction of the first steel bar 200, but in other embodiments, if a diamond mesh reinforcement is required to be welded, the first direction may also form an acute angle with the axial direction of the first steel bar 200. In this embodiment, in order to improve the guiding effect of the blanking inclined plane, as shown in fig. 1, a plurality of blanking plates 501 are disposed on the blanking frame, and the blanking inclined planes of the plurality of blanking plates 501 are located in the same plane. Alternatively, the plurality of blanking plates 501 are arranged at equal intervals.
Since the positioning accuracy between the second reinforcing steel bar 300 dropped from the blanking plate 501 and the first reinforcing steel bar 200 located below the second reinforcing steel bar 300 is poor, in order to improve the positioning accuracy between the second reinforcing steel bar 300 and the first reinforcing steel bar 200, the reinforcing steel bar mesh production apparatus in this embodiment further includes a reinforcing steel bar positioning device 100. The reinforcing bar positioner 100 that this embodiment provided can realize the accurate positioning to warp reinforcing bar and weft reinforcing bar, satisfies the customer and to different specification weft reinforcing bar fixed-position welding's demand, avoids the poor weft reinforcing bar of straightness accuracy to fall the condition appearance that the position frequently blocks pause in work.
Specifically, as shown in fig. 1 to 3, the reinforcing bar positioning device 100 includes a positioning mechanism 1 and a wire pushing mechanism, and the positioning mechanism 1 is located at one side of the first reinforcing bar 200 and the welding device 400. In this embodiment, the positioning mechanism 1 may be a magnetic adsorption body or a general positioning block without an adsorption function. When positioning mechanism 1 was the magnetic adsorption body, the magnetic adsorption body can adsorb second reinforcing bar 300 to realize the preliminary location of first reinforcing bar 200 and second reinforcing bar 300. When the positioning mechanism 1 is a common positioning block, it is necessary to ensure that the height of the positioning block is greater than the sum of the height of the lower electrode 402 and the height of the first steel bar 200, so that when the second steel bar 300 rolls from the blanking device 500 to the positioning block or the second steel bar 300 is pushed to the positioning block by the wire pushing mechanism, the second steel bar 300 can be blocked by the positioning block, and the second steel bar 300 cannot roll along the first direction any more.
The wire pushing mechanism is used for pushing the second steel bar 300, and secondary positioning of the first steel bar 200 and the second steel bar 300 is achieved. As shown in fig. 1 to fig. 3, the wire pushing mechanism includes a driving unit and a wire pushing unit, which are in transmission connection, the driving unit can drive the wire pushing unit to move, and the wire pushing unit can push the second steel bar 300 so that the second steel bar 300 is pressed against the positioning mechanism 1. In this embodiment, the driving mechanism is a cylinder 2 fixed on the blanking plate 501, and a cylinder rod 21 of the cylinder 2 is connected to a wire pushing unit, and the wire pushing unit can push the second steel bar 300 to move when the cylinder rod 21 extends and contracts. Of course, in other embodiments, the driving mechanism may also be other mechanisms with a telescopic function, such as a combination of a motor and a screw-nut mechanism, and the like, and is not limited in detail herein.
As shown in fig. 3, the wire pushing unit includes a wire pushing block 3, a wire pushing front end block 4, and an elastic body 5. One end of the push wire front end block 4 is fixedly connected with a cylinder rod 21 of the cylinder 2, and the connection mode can be selected to adopt screw thread connection. The other end of the wire pushing front end block 4 is connected with the wire pushing block 3 in a sliding mode, the sliding connection mode is not limited, for example, a sliding block can be arranged on the wire pushing front end block 4, a sliding groove is arranged on the wire pushing block 3, and the sliding connection of the wire pushing front end block 4 and the wire pushing block 3 is achieved through the sliding of the sliding block in the sliding groove. An accommodating groove 41 is formed in the wire pushing front end block 4, the elastic body 5 is arranged in the accommodating groove 41, one end of the elastic body 5 is abutted against the bottom of the accommodating groove 41, and the other end of the elastic body is abutted against the wire pushing block 3. When the push wire block 3 slides relative to the push wire front end block 4, the amount of deformation of the elastic body 5 can be changed. The elastic body 5 can make the second reinforcing bar 300 act more smoothly in the process of being pushed, thereby playing a role of buffering in the secondary positioning process of the second reinforcing bar 300 and the first reinforcing bar 200. In this embodiment, the elastic body 5 is a spring, and an initial deformation amount of the spring may be adjusted according to the diameter of the second reinforcing bar 300. Of course, in other embodiments, only the wire pushing block 3 may be provided, so that the wire pushing block 3 is directly and fixedly connected to the cylinder rod 21 of the cylinder 2, but this pushing manner is relatively rigid and cannot ensure smooth movement of the second steel bar 300.
Further, in order to simultaneously realize the accurate positioning of different parts on one second steel bar 300 and a plurality of first steel bars 200, in this embodiment, the number of the positioning mechanisms 1 and the wire pushing mechanisms is set to be plural, the plurality of positioning mechanisms 1 are arranged at intervals along the axis direction of the second steel bar 300, the plurality of wire pushing mechanisms are also arranged at intervals along the axis direction of the second steel bar 300, and the positioning mechanisms 1 and the wire pushing mechanisms are arranged at intervals. Alternatively, the number of the positioning mechanisms 1 and the wire pushing mechanisms may be equal or different. The adjacent positioning mechanism 1 and the wire pushing mechanism can be arranged just opposite to each other or arranged in a staggered manner.
In order to prevent the second reinforcing steel bar 300 from being lifted during pushing, a limiting groove 31 for accommodating the second reinforcing steel bar 300 is arranged at one end of the wire pushing block 3 far away from the wire pushing front end block 4. The limiting groove 31 may be a V-shaped groove or an arc-shaped groove, and in this embodiment, a V-shaped groove is selected as the limiting groove 31. In order to facilitate the installation push away a mechanism and in order to reduce the degree of difficulty that promotes second reinforcing bar 300, in this embodiment, with cylinder 2 and push away the equal slope setting of a mechanism, specific restriction is not done to inclination, specifically sets for according to particular case to the direction of promotion that makes push away a mechanism is certain contained angle with first direction. In addition, the wire pushing mechanism is obliquely arranged, and the purpose of preventing the second steel bar 300 from being jacked up in the pushing process can be achieved.
The method for producing the reinforcing mesh by the reinforcing mesh production equipment comprises the following steps:
first, a plurality of first reinforcing bars 200 are arranged in parallel, and a welding device 400 is disposed at each first reinforcing bar 200. Specifically, a lower electrode 402 is arranged below the first steel bar 200, an upper electrode 401 is arranged above the first steel bar, and a positioning mechanism 1 is arranged on one side of the lower electrode 402;
then the second steel bar 300 rolls off from the inclined blanking surface of the blanking device 500, so that the second steel bar 300 falls onto the plurality of first steel bars 200. The axial direction of the first steel bar 200 is vertical to the axial direction of the second steel bar 300, and under the action of inertia or the magnetic adsorption of the positioning mechanism 1, the second steel bar 300 can roll to the positioning mechanism 1 and is blocked by the positioning mechanism 1, so that the primary positioning of the first steel bar 200 and the second steel bar 300 is realized;
finally, the cylinder 2 controls the cylinder rod 21 to extend and push the wire pushing front end block 4 to move, the wire pushing front end block 4 drives the wire pushing block 3 to move synchronously, and the wire pushing block 3 pushes the second steel bar 300 to enable each section of the second steel bar 300 to be pressed on the corresponding positioning mechanism 1, so that secondary positioning of the first steel bar 200 and the second steel bar 300 is achieved, and positioning accuracy of the first steel bar 200 and the second steel bar 300 is improved. In the process that the wire pushing block 3 pushes the second steel bar 300 to move, the elastic body 5 positioned inside the wire pushing front end block 4 can play a role in buffering, so that the second steel bar 300 can move stably, and the positioning accuracy of the second steel bar 300 and the first steel bar 200 can be further improved.
