Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic metal welding, in particular to an ultrasonic metal welding half-wave T-shaped welding head. Background Art

[0002] The amplitude of the ultrasonic metal welding machine is a key parameter for the material to be welded, which is equivalent to the temperature of ferrochrome. If the temperature is not reached, it will not be welded. If the temperature is too high, the raw materials will be burned or the structure will be damaged and the strength will deteriorate. Because each company chooses different transducers, the amplitude of the transducer output is different. By adapting the amplitude rods and welding heads with different transformation ratios, the working amplitude of the welding head can be corrected to meet the requirements.

[0003] Because of the 20KHz frequency design requirement of conventional welding heads, a slight change of more than 0.5mm in the lateral dimension of the welding area of ​​the welding head will change the required frequency of the welding head, which will cause the dimensions of the entire welding head to change in order to design the required 20KHz frequency requirement. The welding points of conventional welding heads are designed to be very short, and usually the height between two welding points will not exceed 75mm. Due to the short welding points of the welding head, when welding high-power products, the heat energy of the welding area will quickly transfer to the entire welding head. The welding head heats up and the frequency is not within the 20KHz frequency range. This vicious cycle continues until the welding head is damaged. Therefore, we propose an ultrasonic metal welding half-wave T-shaped welding head. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides an ultrasonic metal welding half-wave T-shaped welding head, which has the function of changing the lateral size of the welding area within 6mm by setting the welding head while keeping the overall size unchanged, and still does not affect the welding head within the required 20KHz frequency range, thereby reducing the design time, and being able to prepare uniform standard size blanks in advance to reduce production time and improve production efficiency, thereby achieving cost reduction and efficiency increase. The welding head has a high welding point, which effectively avoids welding of foreign workpieces. The "K"-shaped structure welding point design of the welding head can more fully and effectively transmit the ultrasonic vibration energy to the welding area, making the welding quality more stable and energy consumption The advantages of lower welding head solve the problem that due to the 20KHz frequency design requirement of conventional welding heads, the lateral size of the welding area of ​​the welding head will change the required frequency of the welding head as long as it changes slightly by more than 0.5mm, thereby causing the dimensions of the entire welding head to change in order to design the required 20KHz frequency requirement. The welding points of conventional welding heads are designed to be very low, and usually the height between the two welding points will not exceed 75mm. Due to the low welding points of the welding head, when welding high-power products, the heat energy of the welding area will quickly transfer to the entire welding head, and the welding head will heat up, resulting in the frequency being out of the 20KHz frequency range, and a vicious cycle will occur until the welding head is damaged.

The welding head has a high welding point, which effectively avoids welding of foreign workpieces.

By setting the size of the insulation area to be small, it can effectively insulate and dissipate heat, and effectively solve the problem of heat energy conducted from the welding area to the welding head, causing damage to the welding head.

[0010] As a preferred technical solution of the utility model, the plurality of welding teeth are all in a step-step shape. By setting the welding teeth in a step-step shape, the welding teeth can perform welding better and conduct heat.

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-6 , which is the first embodiment of the present utility model, provides a half-wave T-shaped welding head for ultrasonic metal welding, including a connection end 1. To the right of the connection end 1, there are:

[0027] A welding head main body 2, the welding head main body 2 is integrally set in the shape of "king". The welding head main body 2 includes a central welding end 21, the central welding end 21 is set as a rectangle, both the upper and lower ends of the central welding end 21 are fixedly connected with connection welding ends 22. The connection parts of the two connection welding ends 22 and the central welding end 21 are all rounded. At the opposite ends of the two upper connection welding ends 22, main welding ends 23 are fixedly connected respectively. The lengths of the two main welding ends 23 are longer than the length of the central welding end 21. The connection part of the main welding end 23 and the connection welding end 22 is rounded. On the opposite sides of the two main welding ends 23, a plurality of welding teeth 24 are fixedly connected respectively. The plurality of welding teeth 24 are evenly distributed on the surface of the main welding end 23.

[0028] Heat insulation areas 221 are provided on both the front and back sides of the two connection welding ends 22. The heat insulation areas 221 are recessed on the surface of the connection welding ends 22.

[0029] The plurality of welding teeth 24 are all in the shape of a trapezoid. The end of the plurality of welding teeth 24 far from the main welding end 23 is smaller than the end close to the main welding end 23, and the outer end of the welding tooth 24 protrudes.

[0030] Limit slots 11 are provided on both the front and back sides of the connection end 1. The connection parts of the limit slots 11 and the central welding end 21 are all rounded.

[0031] During the use process, after installing the connection end 1 on the ultrasonic metal welding machine through the installation main body 3, the welding head main body 2 is used to weld the device to be welded;

[0032] When welding, place the welding head main body 2 at the welding position. Through the limit slots 11 on the connection end 1, the welding head main body 2 can be stuck at the welding position to keep the welding head main body 2 stable during welding. The heat on the ultrasonic metal welding machine is conducted to the welding head main body 2 through the installation main body 3 and the connection end 1. After the central welding end 21 senses the heat, the central welding end 21 conducts the heat to the main welding end 23 through the connection welding end 22, so that the welding teeth 24 on the main welding end 23 can generate heat, and the welding part is welded through the welding teeth 24. When the welding head main body 2 is welding, part of the heat can be insulated through the heat insulation areas 221 on the connection welding end 22, thereby preventing other positions from contacting the connection welding end 22 and conducting the heat to other positions. At the same time, the heat dissipation effect between other positions and the connection welding end 22 is increased, and other positions of the device are prevented from being damaged by heat;

[0033] After the installation body 3 senses the high-frequency vibration energy of the ultrasonic metal welding machine, the high-frequency vibration energy is transmitted to the welding head body 2 through the connecting end 1. The high-frequency vibration energy of the welding head body 2 and the high-frequency vibration friction between the weldment cause the friction point to generate heat and transfer heat outward, thereby welding the weldment.

[0034] Example 2

[0035] Reference Figure 1-6 , which is the second embodiment of the utility model, a mounting body 3 is fixedly connected to the left side of the connecting end 1, the right end of the mounting body 3 and the left side of the connecting end 1 are rounded, and a threaded mounting groove 31 is opened on the left side of the mounting body 3.

[0036] During use, the installation body 3 is installed on the ultrasonic metal welding machine, so that the installation body 3 is threadedly installed on the output end of the ultrasonic metal welding machine through the threaded installation groove 31 to keep the installation body 3 stable.

[0037] The remaining structures are the same as those of Example 1.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
