Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a pressure welding device for necklace production. Background Technique

[0002] When designing a necklace, in order to fit the neck more closely and be more convenient to wear, it is usually set in sections, and then the metal pieces at both ends of the necklace are clamped and squeezed by special pliers and welded together so that the necklace can form a ring-shaped structure to be worn on a person.

[0003] When the necklace is directly squeezed and welded manually, there are certain errors, resulting in uneven product quality. In the prior art, the upper welding rod is toggled upward and the metal pieces at both ends of the gold necklace are placed on the upper end of the lower welding rod. At the same time, the lower welding rod slides down naturally and abuts against the metal piece, and then the impact member is started. The impact member hammers the upper welding rod, and the upper welding rod moves downward, so that the metal pieces at both ends of the gold necklace are deformed under pressure and welded together. In this way, the process of pressure welding is relatively stable and accurate. However, in the actual use process, it is necessary to pull the upper welding rod while placing the necklace, resulting in inconvenient operation for the operator and difficulty in operation, thus lacking a certain practicality.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Refer to Figures 1-4 , a pressure welding device for necklace production, including a main body component 1; the main body component 1 includes a U-shaped plate 11, the inner side of which is fixedly connected with a processing plate 12; a lower welding support rod 13, arranged on the processing plate 12; an upper welding support rod 14, arranged on the U-shaped plate 11; a mounting frame 15, fixedly connected to the top of the U-shaped plate 11; a cylinder 16, fixedly connected to the top of the mounting frame 15, and the output end penetrates through the mounting frame 15; a limit component 2 is arranged on the U-shaped plate 11, and the limit component 2 includes: a box body 21, fixedly connected to the top of the U-shaped plate 11; a moving plate 22, penetrating through the box body 21; a movable plate 23, fixedly connected to the outer side wall of the moving plate 22; a first spring 24, arranged on the movable plate 23; a limiting plate 25, inserted into the box body 21 and symmetrically arranged in two; a fixed plate 26, fixedly connected to the outer side wall of each limiting plate 25; a second spring 27, arranged on each fixed plate 26; a limiting block 5 is fixedly connected to the top of each limiting plate 25; anti-slip patterns are arranged on each limiting plate 25.

[0028] When ready for use, the operator places the U-shaped plate 11 at the designated position. Subsequently, the operator pulls the moving plate 22 to drive the upper welding support rod 14 to move upward. When the moving plate 22 moves, it drives the movable plate 23 to slide upward in the box body 21 and stretches the first spring 24 by the movable plate 23. The continuous movement of the moving plate 22 drives the movable plate 23 to squeeze the two side limiting plates 25, causing the limiting plates 25 to move outward from the box body 21, thereby stretching the second spring 27 through the fixing plate 26 thereon. When the movable plate 23 completely passes the limiting plate 25, at this time, the second spring 27 drives the limiting plate 25 to bounce back to limit the movable plate 23, thereby limiting the upper welding support rod 14, facilitating the operator to place the necklace on the lower welding support rod 13 on the processing plate 12. After placing, the operator simultaneously pulls the two side limiting plates 25 to move outward to cancel the limitation of the movable plate 23, so that the movable plate 23 is pulled by the first spring 24 to drive the upper welding support rod 14 to pre-fix the necklace. Subsequently, the operator activates the cylinder 16 on the mounting bracket 15 to make the cylinder 16 impact the moving plate 22 downward, thereby driving the upper welding support rod 14 to move downward, causing the metal sheets at both ends of the necklace to be deformed under pressure and welded together, thus improving the practicability of the device; a limiting block 5 is fixedly connected to the top of each limiting plate 25. When the limiting plate 25 moves, it drives the limiting block 5 to move simultaneously. The limiting block 5 can limit the moving direction of the limiting plate 25 to prevent the limiting plate 25 from being skewed under the elastic force of the second spring 27 during movement, resulting in the jamming of the limiting plate 25 and requiring the operator to manually correct it, thereby improving the stability of the device; anti-slip lines are provided on each limiting plate 25, and the anti-slip lines can increase the friction between the operator's fingers and the limiting plate 25, thereby preventing the operator's fingers from slipping when pulling the limiting plate 25.

[0029] Embodiment 2

[0030] Refer to Figures 1-4 , an auxiliary function is added on the basis of Embodiment 1;

[0031] An auxiliary component 3 is provided on the U-shaped plate 11. The auxiliary component 3 includes: a mounting plate 31 fixedly connected to the rear surface of the box body 21; a push plate 32 inserted into the mounting plate 31; a rotating rod 33 hinged to the outer side wall of the push plate 32 and symmetrically provided with two; a driving plate 34, with a driving plate 34 hinged to one end of each rotating rod 33; a third spring 35 fixedly connected to the bottom of the push plate 32; a plate body 6 fixedly connected to the outer side wall of the push plate 32; a guide rail cover 4 is provided on each driving plate 34.

[0032] After the necklace is placed, the operator presses the push plate 32 to move the push plate 32 into the interior of the mounting plate 31, and drives the two driving plates 34 to move to both sides through the two rotating rods 33. At the same time, the push plate 32 compresses the third spring 35. When the two driving plates 34 move, they drive the two limiting plates 25 to move to both sides through the fixing plates 26 on the same side, so as to cancel the limitation of the movable plate 23. There is no need for the operator to pull the limiting plates 25 on both sides respectively, thus improving the convenience of the device; A plate body 6 is fixedly connected to the outer side wall of the push plate 32. The plate body 6 can limit the moving range of the push plate 32, prevent the operator from operating by mistake and causing the push plate 32 to completely enter the interior of the mounting plate 31, thus improving the stability of the device; A guide rail guard 4 is arranged on each driving plate 34. When the driving plate 34 moves, it drives the guide rail guard 4 to fold or unfold at the same time. The guide rail guard 4 can always cover the sliding groove of the driving plate 34 on the mounting plate 31, prevent dust and other impurities from entering the interior of the mounting plate 31 and causing blockage of the interior of the mounting plate 31, thus improving the safety of the device.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
