Description

Technical Field

[0001] This utility model relates to the field of high-frequency welding induction coil manufacturing technology, specifically to a tooling for manufacturing high-frequency welding induction coils for saw blade welding teeth. Background Technology

[0002] In the saw blade manufacturing process, the welding quality of the saw teeth is crucial. Traditional high-frequency welding induction coils often only heat one side of the saw blade when welding the saw teeth, resulting in unsatisfactory welding effects, insufficient bonding strength between the saw teeth and the saw blade, and impacting the saw blade's lifespan and working efficiency. To improve welding quality, a new type of high-frequency welding induction coil capable of heating both sides of the saw blade simultaneously is needed.

[0003] like Figure 1 As shown, the existing novel high-frequency welding induction coil 100 is made by bending a hollow square tube, including a first bending part 101, two second bending parts 102, two third bending parts 103, a fourth bending part 104, a fifth bending part 105, and a sixth bending part 106. The first bending part 101 and the two second bending parts 102 form an upward-turned head 107; the two second bending parts 102 and the two third bending parts 103 form two parallel side heating parts 108; the fourth bending part 104 forms a first upward-turned connector 109 at one end of the square tube, which is turned upward and away from the two side heating parts 108; the fifth bending part 105 and the sixth bending part 106 form a second upward-turned connector 110 at the other end of the square tube, which is turned upward and away from the two side heating parts 108 and is arranged on the same side as the first upward-turned connector 109. In use, the heating device is connected through the first upturned connector 109 and the second upturned connector 110 to allow the heating circulating fluid to flow inside the square tube. The two side heating parts 108 heat and weld the saw teeth on both sides of the saw blade. During the heating and welding process, the upturned head 107 can pass through the saw teeth, so that the welding will not be hindered by the excessive length of the saw teeth.

[0004] However, there is a lack of tooling available for manufacturing induction coils of this special shape, making it difficult to meet production needs. Therefore, it is particularly necessary to design a new type of high-frequency welding induction coil manufacturing tooling that can easily and accurately bend hollow square tubes into the required shape.

[0010] Preferably, the rear center of the second plate has a gripping opening that extends through its thickness direction to facilitate gripping by the worker, and has a diamond-shaped cross-section.

[0011] Preferably, the tooling further includes a sand container for injecting sand into the square tube under external force to prevent the square tube from being flattened during bending.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] A tooling for fabricating high-frequency welding induction coils for welding saw blade teeth, combined with... Figures 2 to 5 As shown, the assembly includes a first tool 1, a second tool 2, a sand container 3, and flat-nose pliers. The sand container 3 is used to fill the square tube with sand, thus preventing the tube from being flattened during bending. The first tool 1 is used to bend the square tube, thereby creating a first bent section 101, a second bent section 102, and a third bent section 103. The second tool 2 is used in conjunction with the first tool 1 to create the first bent section 101 and the third bent section 103. The flat-nose pliers are used to bend the square tube, thereby creating a fourth bent section 104, a fifth bent section 105, and a sixth bent section 106. During the manufacturing process, the use of the first tool 1, the second tool 2, the sand container 3, and the flat-nose pliers all require external force, specifically the force applied by the worker's hands.

[0029] The sand container 3 includes a cylinder 31 and a syringe 32. The cylinder 31 is used to hold fine sand. The syringe 32 is inserted through the top of the cylinder 31 and is used to inject an appropriate amount of sand into the square tube. Before filling the square tube with sand, one end of the square tube is sealed, and after filling the square tube with sand, the other end of the square tube is sealed to prevent the sand from leaking out of the square tube.

[0030] The first plate tool 1 includes a first plate body 11. A plurality of first bending posts 12 are erected on the front end of the upper surface of the first plate body 11. A first bending inlet 13 is formed between the plurality of first bending posts 12. The first bending inlet 13 is arranged along the width direction of the first plate body 11 and is used to insert a square tube to process a first bending part 101. A slot 16 is opened on the side of the front end of the first plate body 11. The slot 16 is opened through the width direction of the first plate body 11 and is used to insert the first bending part 101 to process a second bending part 102, forming an upturned head 107. A plurality of second bending posts 14 are erected in the middle of the upper surface of the first plate body 11. A second bending inlet 15 is formed between the plurality of second bending posts 14. The second bending inlet 15 is arranged along the length direction of the first plate body 11 and is used to insert a square tube to process a third bending part 103, forming a side heating part 108.

[0031] Specifically, the slot 16 includes a trapezoidal slot 161 and a rectangular slot 162. The trapezoidal slot 161 is located on the outer side and has a cross-section that is wider on the outside and narrower on the inside. The rectangular slot 162 is located on the inner side and communicates with the trapezoidal slot 161. When the first bend 101 end of the square tube forming the first bend 101 is inserted into the slot 16, the square tube is manually bent upwards. Under the limitation of the trapezoidal slot 161, a flip-up head 107 with a specific angle can be formed.

[0032] The second tool 2 includes a second plate body 21. The front end of the second plate body 21 is a trapezoid that gradually narrows on both sides, and a rectangular clamping groove 22 is provided in the middle of its front end along its length direction and extending through its thickness direction. The rectangular clamping groove 22 is used to clamp the square tube after it is inserted into the first bending socket 13. A pinching opening 23 is provided in the middle of the rear end of the second tool 2. The pinching opening 23 extends through the thickness direction of the second tool 2. The pinching opening 23 makes it easy for the worker to pinch the second plate body 21. After the rectangular clamping groove 22 clamps the square tube, the worker can easily pinch the pinching opening 23 to apply force to the second plate body 21 and bend the square tube.

[0033] Flat-nose pliers are existing technology. By holding the flat-nose pliers and applying force with their hands, workers can bend the square tube from one end to form the fourth bend 104, forming the first upturned connector 109; and bend the square tube from the other end to form the fifth bend 105 and the sixth bend 106, forming the second upturned connector 110.

[0034] In use, this invention involves first sealing one end of a straight square tube, then filling the tube with sand using a sand-filling cylinder 3, and finally sealing the other end of the square tube; then... Figure 6 As shown, insert the square tube into the first bending socket 13 from a suitable position. Then, insert the rectangular clamping groove 22 of the second plate 21 into the square tube from a suitable position, and pinch the second plate 21 from the pinching opening 23, forcefully rotating the second plate 21 to bend the square tube to a suitable angle. At this point, the bending angle is less than the bending angle of the first bending section 101. The square tube can be further bent using flat-nose pliers until the first bending section 101 is formed. Figure 7 As shown, during this process, the square tube can be tapped to make the first bend 101 of the square tube horizontal so that it can be inserted into the slot 16 in the next step; then, as Figure 8 As shown, the first bent portion 101 is inserted into the slot 16, and the exposed square tube is turned upwards by hand until it fits against the trapezoidal slot 161, thus forming the second bent portion 102 and creating the upturned head 107. Figure 9 As shown; then, as Figure 10 As shown, the square tube forming the upturned head 107 is inserted into the second bending socket 15 and adjusted to a suitable position. The second plate 2 is placed against the bottom of the square tube from the side away from the upturned head 107. The square tube is then flipped upwards by 180° by hand against the second plate 2, forming the third bending part 103 and the side heating part 108. Figure 11 As shown; finally, use flat-nose pliers to bend a fourth bend 104 from one end of the square tube to form a first upturned connector 109, and bend a fifth bend 105 and a sixth bend 106 from the other end of the square tube to form a second upturned connector 110. Cut off both ends of the square tube and pour out the sand.
