Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline production equipment and relates to a trap welding device. Background Art

[0002] In plastic processing, hot melt connection is a common welding technology applicable to the connection between non-metallic materials. This connection method involves heating to the melting point of the material to melt the plastic and then joining them together. Hot melt connection has the advantages of simple connection, long service life, and corrosion resistance, and is widely used in the connection of pipeline systems and other plastic products.

[0003] Chinese Patent with application publication number CN115284616A discloses a PTFE pipe welding method, which involves docking the two butting edges of the bent PTFE plate so that the bent PTFE plate basically forms a circular PTFE pipe, passing an arc-shaped support plate through the PTFE pipe, and clamping the butting edges of the PTFE pipe to be welded with the arc-shaped upper pressing plate and the arc-shaped support plate that are opposite to each other up and down; two electric heating devices corresponding to the two butting edges are arranged on the lower surface of the support plate, and the electric heating devices extend in the direction parallel to the axial direction of the support plate; by pressing the upper pressing plate to clamp the butting edges of the PTFE pipe located between the upper pressing plate and the support plate, the two electric heating devices heat and weld the butting edges to be welded, and the welded PTFE pipe is obtained after cooling.

[0004] When the above device is welding, it first aligns and fixes the butting edges, and then heats and melts the butting position, so that the butting edges are self-fused. However, it is difficult for the molten material to flow sufficiently only relying on its own potential energy, often resulting in some positions of the weld still having voids, leading to a decline in welding quality. Summary of the Invention

[0005] Aiming at the above-mentioned existing technical problems, the utility model provides a trap welding device. The technical problem to be solved by the utility model is that it is difficult for the existing pipeline welding device to ensure the welding quality of the trap.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A trap welding device includes a frame. It is characterized in that an upper lifting plate and a lower lifting plate capable of lifting are respectively arranged on the frame. The upper lifting plate and the lower lifting plate are respectively provided with positioning holes one and two for positioning different trap components. A moving plate capable of translating to the outside of the upper lifting plate and the lower lifting plate is arranged between the upper lifting plate and the lower lifting plate. The moving plate is connected to the frame, and horizontal electric heating plates are respectively arranged on the upper and lower sides of the moving plate.

[0008] By arranging an upper lifting plate and a lower lifting plate that can both move up and down on the rack, and respectively arranging a first positioning hole and a second positioning hole on the upper lifting plate and the lower lifting plate to position different trap pipe components to be welded. At the same time, a moving plate that can translate outwards is arranged between the upper lifting plate and the lower lifting plate, and electric heating plates are arranged on both the upper and lower sides of the moving plate. In this way, during production, different components of the trap pipe are first positioned into the first positioning hole and the second positioning hole respectively, then the moving plate drives the electric heating plates to translate to a position vertically opposite to the trap pipe components. After that, the upper lifting plate and the lower lifting plate move downwards and upwards respectively, so that the trap pipe components contact the high-temperature electric heating plates and the parts to be welded of the trap pipe components are melted. Subsequently, the upper lifting plate and the lower lifting plate can move separately to separate from the electric heating plates, the moving plate then translates to the outside of the upper lifting plate and the lower lifting plate, and finally the upper lifting plate and the lower lifting plate move towards each other and the welded parts of different trap pipe components are vertically contacted and extruded to form a weld, which is beneficial to making the joint part more fully compact. In addition, even after the joint part is melted, it can still maintain its original shape under the influence of gravity, which can avoid misalignment during joining and affecting the welding effect, thereby improving the welding quality of the trap.

[0009] In the above-mentioned trap welding equipment, the lower lifting plate includes a positioning plate and a clamping plate that can reciprocally translate relative to the positioning plate. The clamping plate abuts against the positioning plate and forms the second positioning hole therebetween. When the clamping plate separates from the positioning plate, it is convenient to place the trap component in a larger space between the clamping plate and the positioning plate. After that, when the clamping plate moves towards the positioning plate to form an abutment, it can automatically clamp and position the trap component, and the operation is convenient and safe.

[0010] In the above-mentioned trap welding equipment, the top surface of the upper lifting plate has a plurality of guide grooves circumferentially arranged at intervals around the first positioning hole. The guide grooves are all communicated with the first positioning hole, and a clamping block that can reciprocally translate into the inner cavity of the first positioning hole is arranged in the guide grooves. In this way, when the operator puts the trap component into the first positioning hole, the clamping block can translate and clamp and position the outer circumference of the trap component, ensuring the stable position of the trap component. At the same time, the moving position of the clamping block can be separated from the position of the operator's hand, avoiding pinching the operator and ensuring safety.

[0011] In the above-mentioned trap welding device, a first substrate is connected above the ascending and descending plate. A number of first limiting rods vertically arranged downward are fixedly connected to the first substrate. The first limiting rods are arranged around the periphery of the ascending and descending plate and their lower ends extend beyond the bottom surface of the ascending and descending plate. A second substrate is connected below the descending and ascending plate. A number of second limiting rods vertically arranged upward are fixedly connected to the second substrate. The second limiting rods are arranged around the periphery of the descending and ascending plate and their upper ends extend beyond the top surface of the descending and ascending plate. In this way, when the trap components on the ascending and descending plate and the descending and ascending plate are respectively brought into contact with the corresponding heating plates, the first limiting rods and the second limiting rods can respectively abut against the moving plate to form a limit, thereby restricting the moving stroke to avoid excessive melting of the trap components, and further improving the welding quality.

[0012] In the above-mentioned trap welding device, the first limiting rods and the second limiting rods are both arranged in a staggered manner. This is beneficial to avoid interference and obstruction between the first limiting rods and the second limiting rods when the ascending and descending plate and the descending and ascending plate move towards each other to weld different trap components, ensuring a smooth welding process.

[0013] In the above-mentioned trap welding device, strip-shaped sliding rails are respectively provided on the two horizontal sides of the frame. The two sliding rails are arranged in parallel and along the translation direction of the clamping plate. The moving plate is slidably connected to the two sliding rails. This is beneficial to ensure the stability of the moving direction of the moving plate. At the same time, the moving direction of the clamping plate is the same as that of the moving plate, which is beneficial to utilize the vertically overlapping space and make the structure more compact.

[0014] In the above-mentioned trap welding device, a number of vertically arranged guiding rods are provided on the frame. The first substrate and the second substrate are simultaneously slidably connected to the guiding rods. This is beneficial to further provide vertical guidance for the ascending and descending plate and the descending and ascending plate fixedly connected to the first substrate and the second substrate through the guiding rods, ensuring their stable and precise movement and improving the trap welding quality.

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] This trap welding device first melts the joint position of the trap components and then performs vertical docking, which is beneficial to make the joint part more fully compact. In addition, even if the joint part is affected by gravity after melting, it can still maintain its original shape, avoiding misalignment during jointing and affecting the welding effect, and improving the welding quality of the trap.
