Description

Technical Field

[0001] This utility model relates to the field of tin bar production technology, specifically a support structure for a tin bar production line. Background Technology

[0002] Solder bars are a type of soldering product, mainly used for electronic, circuit board, and metal soldering. They are divided into two categories: leaded solder bars and lead-free solder bars. Leaded solder bars use a tin-lead alloy with a melting point of 183℃, suitable for wave soldering or hand dip soldering. Lead-free solder bars comply with RoHS standards and commonly use tin-copper or tin-silver-copper alloys with a melting point of 227℃, used in environmentally friendly and export electronic products. Both types of products have their performance improved by adding antioxidants, resulting in good wettability, excellent fluidity, bright and full solder joints, and low dross. During the production of lead-free solder bars, molten material needs to be poured into a mold, requiring a special support structure to support and fix the mold, ensuring the quality of the solder bar forming.

[0003] In existing support structures, the mold is usually fixed on the support structure. When casting solder bar raw materials, the product cast in the mold needs to be demolded before casting, which affects the production efficiency of solder bar casting. At the same time, the existing solder bar support structure cannot adjust the length of the forming groove in the mold, thus it cannot cast solder bar products of different lengths, which cannot meet the actual application needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a support structure for a tin bar production line. By setting two molds, support rollers, limiting grooves, push-pull plates, push-pull cylinders and limiting sensors, the push-pull cylinders drive the molds to slide laterally along the support rollers in the limiting grooves through the push-pull plates. When the forming groove in one mold is poured and moves to one side, the push-pull cylinder on the other side can push the other mold to the position where it needs to be poured, so that continuous pouring can be carried out. The first mold is demolded, so that the demolding and pouring processes do not interfere with each other, improve production efficiency, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support structure for a tin bar production line, including a support frame, a limit groove provided on the upper side of the support frame, support rollers equally spaced on the bottom side of the limit groove, two molds provided on the upper side of the support rollers, limit sensors installed at the center of opposite sides of the molds, a forming groove formed on the upper side of the molds, a stripping template placed on the upper side of the forming groove, a liquid-blocking protrusion installed on the lower side of the stripping template corresponding to the position of the forming groove, a bottom plate formed below the liquid-blocking protrusion, a limit protrusion formed on the upper side of the bottom plate, a push-pull plate fixedly installed on the side of the mold away from the limit sensor, and a push-pull cylinder fixedly connected to the lower part of the end of the push-pull plate away from the mold.

[0006] Furthermore, a fixing seat is fixedly installed on the upper side of the template, and a fixing groove is opened in the fixing seat, and a handrail is installed in the fixing groove.

[0007] Furthermore, bolt holes are provided at the connection positions of the fixed base and the handrail, and the support roller is connected to the support frame through bearings.

[0008] Furthermore, the end of the push-pull cylinder away from the push-pull plate is fixedly connected to the support frame, and the liquid-blocking protrusion is slidably connected to the forming groove.

[0009] Furthermore, the liquid-blocking protrusion is bolted to the demolding template, and the fixing seat is welded to the demolding template.

[0010] Furthermore, the bottom plate of the groove is in contact with the bottom surface of the forming groove, and the mold and the support frame are slidably connected through the support roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses two molds, support rollers, limiting grooves, push-pull plates, push-pull cylinders, and limiting sensors to enable the push-pull cylinders to drive the molds to slide laterally along the support rollers in the limiting grooves via the push-pull plates. When the forming groove in one mold is poured and moves to one side, the push-pull cylinder on the other side can push the other mold to the position where it needs to be poured, thus enabling continuous pouring. The first mold is demolded, so that the demolding and pouring processes do not interfere with each other, improving production efficiency. 2. This utility model, through the setting of a stripping template, a liquid-blocking protrusion, a bottom plate of the mold, and a limiting protrusion, allows the liquid-blocking protrusion on the lower side of the stripping template to move along the molding groove, thereby adjusting the position of the liquid-blocking protrusion in the molding groove, so that the length of the solder bar formed in the molding groove can be adjusted to meet production requirements.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a support structure for a tin bar production line, including a support frame 1. A limit groove 3 is provided on the upper side of the support frame 1. Support rollers 2 are provided at equal intervals on the bottom side of the limit groove 3. Two molds 14 are provided on the upper side of the support rollers 2. Limit sensors 15 are installed at the center of opposite sides of the molds 14. A forming groove 4 is formed on the upper side of the molds 14. A stripping template 7 is placed on the upper side of the forming groove 4. A liquid-blocking protrusion 16 is installed on the lower side of the stripping template 7 corresponding to the position of the forming groove 4. A bottom plate 12 is formed at the lower part of the liquid-blocking protrusion 16. A limit protrusion 13 is formed on the upper side of the bottom plate 12. A push-pull plate 5 is fixedly installed on the side of the mold 14 away from the limit sensor 15. A push-pull cylinder 6 is fixedly connected to the lower part of the end of the push-pull plate 5 away from the mold 14.

[0016] like Figure 1-4 As shown, during the molding and casting process, the push-pull cylinder 6 drives one of the molds 14 to move along the support roller 2 in the limiting groove 3 to the upper center position of the support frame 1 via the push-pull plate 5. The casting device pours the molten raw material into the molding groove 4 of the mold 14. After casting, the push-pull cylinder 6 drives the cast mold 14 away from the casting position via the push-pull plate 5. At the same time, another push-pull cylinder 6 drives another mold 14 to move towards the upper center position of the support frame 1 via another push-pull plate 5, so that the other mold 14 can be cast. The mold 14 that has been cast can be demolded at the same time, so that the production of solder bars can be carried out continuously, improving production efficiency. The liquid-blocking protrusion 16 on the lower side of the demolding plate 7 can move along the molding groove 4, thereby adjusting the position of the liquid-blocking protrusion 16 in the molding groove 4 and adjusting the molding length of the molding groove 4, so that the molding length of the solder bars can be adjusted to meet the actual use requirements.

[0017] A fixing seat 8 is fixedly installed on the upper side of the demolding template 7. A fixing groove 10 is opened in the fixing seat 8. A handrail 9 is installed in the fixing groove 10. The handrail 9 makes it convenient for the operator to pry up the molding tin strip in the molding groove 4 through the bottom plate 12 on the lower side of the demolding template 7 to demold.

[0018] Bolt holes 11 are provided at the connection positions of the fixed base 8 and the handrail 9. The support roller 2 is connected to the support frame 1 through a bearing. After the bolt is inserted into the bolt hole 11, the handrail 9 can be firmly connected to the fixing groove 10 in the fixed base 8.

[0019] The end of the push-pull cylinder 6 away from the push-pull plate 5 is fixedly connected to the support frame 1. The liquid-blocking protrusion 16 is slidably connected to the forming tank 4. The liquid-blocking protrusion 16 can block the liquid dilute raw material in the forming tank 4, thereby adjusting the forming length of the solder bar.

[0020] The liquid-blocking protrusion 16 is connected to the demolding template 7 by bolts, and the fixing seat 8 is welded to the demolding template 7.

[0021] The bottom plate 12 of the groove is in contact with the bottom surface of the forming groove 4, and the mold 14 and the support frame 1 are slidably connected through the support roller 2.

[0022] The working principle of the support structure for a tin bar production line provided by this utility model is as follows: Figures 1-4 As shown, during the molding and casting process, the push-pull cylinder 6 drives one of the molds 14 to move along the support roller 2 in the limiting groove 3 to the upper center position of the support frame 1 via the push-pull plate 5. The casting device pours the molten raw material into the molding groove 4 of the mold 14. After casting, the push-pull cylinder 6 drives the cast mold 14 away from the casting position via the push-pull plate 5. At the same time, another push-pull cylinder 6 drives another mold 14 to move towards the upper center position of the support frame 1 via another push-pull plate 5, so that the other mold 14 can be cast. The mold 14 that has been cast can be demolded at the same time, so that the production of solder bars can be carried out continuously, improving production efficiency. The liquid-blocking protrusion 16 on the lower side of the demolding plate 7 can move along the molding groove 4, thereby adjusting the position of the liquid-blocking protrusion 16 in the molding groove 4 and adjusting the molding length of the molding groove 4, so that the molding length of the solder bars can be adjusted to meet the actual use requirements.
