Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, and in particular relates to a semi-automatic welding equipment for diamond composite sheets for drill bits. Background Technology

[0002] The composite diamond drill bit body consists of a polycrystalline diamond (PCD or PDC) layer and a cemented carbide matrix (usually tungsten carbide-cobalt). During machining and welding, silver-based or copper-based brazing filler metal is used as the solder, supplemented with flux (such as borax) to remove the oxide layer. During welding, the filler metal acts as a medium, metallurgically bonding the polycrystalline diamond layer and the cemented carbide matrix under high temperature conditions to form a high-strength composite structure.

[0003] There are two existing welding methods: fully automatic and manual. Fully automatic welding is more efficient, but for small-batch manufacturers, the purchase cost of fully automatic welding equipment is high. Although manual welding can control costs in the short term, it is less efficient and can easily cause safety accidents when welding in high-temperature environments.

[0004] To address the aforementioned issues, this application proposes a semi-automatic welding device for diamond composite sheets used in drill bits. Utility Model Content

[0005] The purpose of this invention is to provide a semi-automatic welding device for diamond composite sheets in drill bits, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a semi-automatic welding equipment for diamond composite sheets for drill bits, comprising a frame, the frame including a base at the bottom and uprights welded to the base, and crossbars fixed to the upper ends of adjacent uprights. A movable frame is provided within the frame, and a chain conveyor belt is provided within the movable frame. A mold for carrying diamond composite sheet material is fixedly installed along the external path of the chain conveyor belt. Above the chain conveyor belt is an electric heating tube that heats and welds the sheet material and is installed at the front end of a heater. An electric cylinder is provided between the movable frame and the uprights to raise the mold to a position close to the electric heating tube.

[0008] Furthermore, a hanger is fixed at the bottom of the movable frame, and a motor is installed on the hanger. The output end of the motor is connected to the sprocket at one end of the chain conveyor belt via belt drive.

[0009] Furthermore, the upper end of the mold is provided with positioning holes for positioning and placing the sheet material, and each mold has at least two positioning holes.

[0010] Furthermore, a support plate for vertical installation of the electric cylinder is fixed on the upright, the output end of the electric cylinder is fixed to the movable frame, and the electric cylinder consists of two symmetrical cylinders that horizontally support the movable frame and the chain conveyor belt.

[0011] Furthermore, several sets of linear tracks are installed between the two sides of the movable frame and the uprights.

[0012] Furthermore, a bracket is installed on the crossbar, and a cooling fan is fixed on the bracket. The cooling fan is located at the rear end of the heating element.

[0013] Furthermore, the cooling fan is tilted and its air outlet faces the welded composite sheet.

[0014] Furthermore, a collection box is placed on the base, located directly below the conveyor end of the chain conveyor belt.

[0015] This utility model has the following beneficial effects:

[0016] This invention enables the composite sheet to be automatically transported to the underside of the heating element by a mold set on the chain conveyor belt. Then, the electric cylinder can automatically send the placed composite sheet to the heating element for welding. Subsequently, the chain conveyor belt can automatically collect it in the collection box, realizing low-cost semi-automatic welding.

[0017] This invention uses a cooling fan to cool and solidify the welded composite sheet, thus accelerating the molding process. The cooling fan is also tilted by a bracket, which helps to cool the sheet while avoiding any impact on the welding position.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figures 1-4 As shown, this utility model is a semi-automatic welding equipment for diamond composite sheets of drill bits, including a frame 1. The frame 1 includes a base 101 at the bottom and uprights 102 welded to the base 101, as well as crossbars 103 fixed to the upper ends of adjacent uprights 102. A movable frame 2 is provided in the frame 1, and a chain conveyor belt 3 is provided in the movable frame 2. A mold 4 for carrying diamond composite sheet material is fixedly installed on the chain conveyor belt 3 along an external path. An electric heating tube 91 is provided above the chain conveyor belt 3 to heat and weld the sheet material and install it at the front end of a heater 9. The heater 9 is placed on another support so that the electric heating tube 91 is directly opposite the mold 4. The accuracy of the alignment between the positioning hole 41 and the electric heating tube 91 can be controlled by a sensor. An electric cylinder 7 is provided between the movable frame 2 and the uprights 102 to raise the mold 4 to be close to the electric heating tube 91.

[0029] The movable frame 2 has a hanging frame 21 fixed at its bottom. A motor 5 is installed on the hanging frame 21. The output end of the motor 5 is connected to the sprocket at one end of the chain conveyor belt 3 through a belt drive 6. The motor 5 and the belt drive 6 are both installed on the movable frame 2 and then cooperate with the chain conveyor belt 3, so that the conveying and lifting of the chain conveyor belt 3 do not interfere with each other.

[0030] The upper end of the mold 4 is provided with positioning holes 41 for positioning and placing the sheet material. Each mold 4 has at least two positioning holes 41, and the number of tube rings on the heating tube 91 should be the same as the number of positioning holes 41.

[0031] Among them, a support plate 104 for vertical installation of electric cylinder 7 is fixed on the upright 102. The output end of electric cylinder 7 is fixed to the movable frame 2. Two electric cylinders 7 are symmetrically arranged to horizontally support the movable frame 2 and the chain conveyor belt 3. The symmetrical arrangement of electric cylinders 7 ensures stable and smooth lifting.

[0032] Among them, several sets of linear rails 8 are installed between the two sides of the movable frame 2 and the upright 102. The linear rails 8 ensure the vertical lifting stability of the movable frame 2.

[0033] The crossbar 103 is equipped with a bracket 1001, and the cooling fan 10 is fixed on the bracket 1001. The cooling fan 10 is located at the rear end of the heating tube 91. The bracket 1001 is fixed to the crossbar 103 by bolts or welding, and the cooling fan 10 is installed to the bracket 1001 by screws, which facilitates assembly and later maintenance, while ensuring a reliable connection.

[0034] Among them, the cooling fan 10 is set at an angle with the air outlet facing the welded composite plate. By adjusting the angle, the cooling effect of the composite plate is ensured while avoiding airflow interference with the welding area.

[0035] Among them, a collection box 11 is placed on the base 101, located directly below the conveying end of the chain conveyor belt 3. The collection box 11 is made of high-temperature resistant metal and can automatically collect the composite sheet after welding and cooling under the action of the chain conveyor belt 3.

[0036] It is understood that this utility model uses a chain conveyor belt in conjunction with a mold to achieve automatic conveying and positioning of composite sheets. The composite sheets are precisely pushed into the heating tube by an electric cylinder for welding, and then automatically transferred to a collection box by the conveyor belt, forming a low-cost semi-automatic welding production line. At the same time, it is equipped with an inclined cooling fan to accelerate the cooling and curing of the welding area. The angle is adjusted to avoid airflow interference in the welding area, effectively improving production efficiency and molding stability.

[0037] A specific application of this embodiment is as follows: A diamond composite sheet is placed in the positioning hole 41 of the mold 4. The motor 5 drives the chain conveyor belt 3 and the mold 4 at its upper end to move through the belt drive 6. After the assembled sheet moves to the position directly below the heating tube 91, the electric cylinder 7 is activated to move upward. The electric cylinder 7 drives the movable frame 2, the chain conveyor belt 3, the mold 4, and the motor 5 to move upward synchronously. The mold 4 directly below the heating tube 91 moves to be close to it. The heater 9 heats the heating tube 91, and the sheet is welded into a diamond composite sheet through high temperature. Then the chain conveyor belt 3 continues to convey the sheet. The welded composite sheet moves to the position below the cooling fan 10. When the cooling fan 10 is working, it cools and solidifies the composite sheet. After the chain conveyor belt 3 continues to convey the sheet, the mold 4 is flipped downward along with the chain conveyor belt 3. The cooled composite sheet automatically falls into the collection box 11, thus completing the welding work.
