Description

Technical Field

[0001] This utility model relates to the field of electroslag pressure welding technology, specifically a clamp-type electroslag pressure welding slag collection device. Background Technology

[0002] Electroslag pressure welding is a widely used rebar connection technology in building construction, suitable for vertical or oblique connections of Grade I to III rebars with diameters ranging from 12mm to 40mm. This welding method utilizes an electric arc and electroslag process generated between the end faces of two rebars to heat the ends to a molten state, followed by pressure to tightly bond the rebars together. Electroslag pressure welding is favored for its high efficiency, low cost, and stable weld quality, and is particularly suitable for thick plate welding, finding wide application in boilers, heavy machinery, and shipbuilding industries. During the welding process, electroslag pressure welding ensures that the mechanical properties of the joint meet requirements, providing a uniform and stable connection effect. The bending angles and protrusions at the joint must meet strict quality standards to ensure the stability and safety of the structure. Currently, during electroslag pressure welding, the welding slag is directly poured into a container held by the operator. This practice not only fails to ensure complete slag collection but also poses a risk of burns to the operator. Furthermore, improper handling of the welding slag can also create a fire hazard.

Detailed Implementation

[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0025] See Figures 1 to 6 This embodiment proposes a clamp-type electroslag pressure welding slag collection device, which includes a right collection shell 1, a left collection shell 2, a left handle 3, a right handle 4, and a collection filling block 5.

[0026] The right collecting shell 1 and the left collecting shell 2 have the same structure, both being semi-circular trough structures with open tops and sides; the right collecting shell 1 and the left collecting shell 2 can be combined to form a circular trough structure with an open top; an arc-shaped right clamping groove 13 is provided at the center of the bottom of the right collecting shell 1, and the right clamping groove 13 is flush with and fixedly connected to the lower surface of the right collecting shell 1; an arc-shaped left clamping groove 6 is provided at the center of the bottom of the left collecting shell 2; the left clamping groove 6 is flush with and fixedly connected to the lower surface of the left collecting shell 2, and the right clamping groove 13 and the left clamping groove 6 work together to clamp the steel bar to be welded.

[0027] The left collection housing 2 is welded to the right handle 4, and the right collection housing 1 is welded to the left handle 3. A connecting shaft 7 is provided at the end of the right handle 4 near the left collection housing 2, and a connecting hole 14 is provided at the end of the left handle 3 near the right collection housing 1. The connecting shaft 7 is rotatably connected in the connecting hole 14, so that the right handle 4 and the left handle 3 are hinged at the connecting shaft 7. The opening and closing of the right collection housing 1 and the left collection housing 2 can be controlled by the right handle 4 and the left handle 3.

[0028] A sliding groove 9 is provided along its axial direction at the bottom of the right handle 4. A slider assembly 10 is slidably connected in the sliding groove 9. A positioning bolt 11 is connected to the slider assembly 10. The positioning bolt 11 passes through the slider assembly 10 and can be pressed against the inner wall of the sliding groove 9. The slider assembly 10 can be positioned by tightening the positioning bolt 11. In order to prevent the slider assembly 10 from coming out of the sliding groove 9, an end cap 8 is provided at the end of the sliding groove 9.

[0029] The bottom of the left handle 3 is connected to one end of the stepless connecting rod 15 via a fixing bolt 16. The other end of the stepless connecting rod 15 is connected to the slider assembly 10 via a positioning bolt 11. A shim 12 is provided between the stepless connecting rod 15 and the positioning bolt 11. The shim 12 is a buffer structure set between the positioning bolt 11 and the stepless connecting rod 15 to adjust the tightness of the stepless connecting rod 15 and absorb impact force. The collection filling block 5 is a movable block placed between the right collection shell 1 and the left collection shell 2 to fill the gap.

[0030] The slag collection device is designed as a clamp-type structure. The opening and closing of the left clamping groove 6 and the right clamping groove 13 are achieved by the relative movement of the left handle 3 and the right handle 4, facilitating the collection of slag generated during the welding process. Both the left collection shell 2 and the right collection shell 1 are made of wear-resistant materials to improve the device's durability and high-temperature resistance. The inner diameter of both the left clamping groove 6 and the right clamping groove 13 is 40mm. In the fully closed state, the distance between the tops of the arcs inside the left and right clamping grooves is 12mm, accommodating the welding requirements of vertical reinforcing bars with diameters ranging from 12mm to 40mm.

[0031] The method of using the clamp-type electroslag pressure welding slag collection device proposed in this embodiment is as follows:

[0032] First, the operator loosens the positioning bolt 11 clockwise and opens the left handle 3 and right handle 4 to an appropriate angle with both hands. Then, the steel bar to be welded is inserted from one side into the wide gap formed between the right collection shell 1 and the left collection shell 2 of the collection device.

[0033] The second step is to adjust the collecting device so that the steel bar to be welded is located between the left clamping groove 6 and the right clamping groove 13. Squeeze the left handle 3 and the right handle 4 and shake them left and right to ensure that the steel bar to be welded is clamped. Squeeze the left handle 3 and the right handle 4 with your left hand and tighten the positioning bolt 11 counterclockwise with your right hand. Then, fix the collecting filling block 5 in the gap between the right collecting shell 1 and the left collecting shell 2 to ensure that there are no gaps at the bottom and sides of the collecting device, forming a complete collecting trough.

[0034] The third step is to open the electroslag pressure welding device and shake the electroslag pressure welding slag into the collection device, namely the tank formed by the right collection shell 1, the left collection shell 2 and the collection filling block 5; to achieve complete collection of electroslag pressure welding slag, without spillage or injury to operators.

[0035] Fourth step: After welding is completed, loosen the positioning bolt 11 on the lower side of the right handle 4 clockwise, open the left handle 3 and the right handle 4 with both hands, take out the collection device, and pay attention to recycling the collection filling block 5 when pouring out the welding slag.

[0036] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
