Description

Technical Field

[0001] This application relates to the field of bolt molds, and more specifically, to a bolt forming mold. Background Technology

[0002] Bolts and screws are the most basic mechanical components, widely used in various industries such as automobiles, industrial machinery and construction. Unlike welding and riveting, the biggest feature of bolts is that they can be easily removed even after being tightened, and can be reused by tightening them again.

[0003] When processing and producing bolts, forming molds are required. Existing forming molds have complex structures and are not convenient to operate, especially for forming a small number of bolts.

[0004] Chinese patent application CN202120543724.6 discloses a bolt forming mold, including a base, a column, a connecting rod, a telescopic rod, and a fixing plate, with the column mounted on the upper end of the base. This invention places the bolt to be formed on two lower pressure rollers, aligning their centers with the center of the line connecting the two rollers. The telescopic rod is activated, extending and moving the upper pressure roller downwards until it contacts the bolt. The bolt is held by hand, and the upper pressure roller continues to move downwards until it contacts the support. At this point, the telescopic rod stops extending and begins to retract, disengaging the upper pressure roller from the bolt. This continues until the upper pressure roller returns to its initial position, and the formed bolt is removed from the support. The upper and lower pressure rollers, as well as the support, are all detachable and replaceable, improving the device's practicality and application range. The overall structure is simple, easy to operate, and has strong potential for widespread use.

[0005] The above solution has the following shortcomings: When using it, the bolt to be formed needs to be placed on two pressure rollers and its center needs to be aligned with the center of the line connecting the two pressure rollers. At the same time, the bolt to be processed needs to be held by hand, which makes it difficult to place and position it quickly, thus reducing work efficiency and the practicality of the device.

The U-shaped fixing frame 125 is located on one side of the worktable 110, and the two pressure rollers 124 are rotatably connected to the U-shaped fixing frame 125. The configuration of the hydraulic cylinder 121, slider 122, pressure block 123, two pressure rollers 124, and U-shaped fixing frame 125 facilitates bolt forming.

[0032] In the specific configuration, grooves 140 are provided on one side of slider 122, pressure block 123, two pressure rollers 124 and U-shaped fixing frame 125. By providing grooves 140 on one side of slider 122, pressure block 123, pressure rollers 124 and U-shaped fixing frame 125, it is convenient for bolts to enter the grooves 140 during bolt forming, which facilitates forming.

[0033] In a specific configuration, the demolding assembly 130 includes an electric push rod 131 and a top block 132. The electric push rod 131 is installed on one side of the U-shaped fixing frame 125, and the top block 132 is connected to the movable end of the electric push rod 131. The top block 132 is slidably connected to the U-shaped fixing frame 125. The electric push rod 131 and the top block 132 facilitate the demolding of the formed bolts.

[0034] Please see Figure 1 , Figure 2 and Figure 4 The positioning structure 20 includes an adjustment component 210, two L-shaped support plates 220, a slide plate 230, and a spring 240. The adjustment component 210 is disposed inside the worktable 110. The two L-shaped support plates 220 are connected to the adjustment component 210. The slide plate 230 is slidably connected to the L-shaped support plates 220. The two ends of the spring 240 are respectively connected to the slide plate 230 and the L-shaped support plates 220.

[0035] In a specific configuration, the adjustment assembly 210 includes a bidirectional lead screw 211 and two lead screw nut pairs 212. The bidirectional lead screw 211 is rotatably connected to the worktable 110, and the two lead screw nut pairs 212 are threadedly connected to the bidirectional lead screw 211. The L-shaped support plate 220 is connected to the lead screw nut pairs 212. The bidirectional lead screw 211 and the two lead screw nut pairs 212 facilitate the positioning of bolts of different lengths, thus improving the practicality of the device.

[0036] In specific settings, a rotating block is provided at one end of the bidirectional lead screw 211. By providing a rotating block at one end of the bidirectional lead screw 211, the user can easily rotate the bidirectional lead screw 211, saving time and effort.

[0037] In the specific setup, a limiting groove is provided on one side of the L-shaped support plate 220, and the slide plate 230 is slidably connected to the limiting groove.

The outer ring of the bolt is attached to the groove 140 opened on one side of the two pressure rollers 124, which facilitates the quick placement and positioning of the bolt to be formed. By opening the hydraulic cylinder 121, the slider 122 and the pressure block 123 are driven to move, so that the pressure block 123 is attached to the bolt. At this time, the pressure block 123 continues to move until the bolt is attached to the U-shaped fixing frame 125. During the movement, the two ends of the bolt push the slide plate 230 to move and squeeze the spring 240. The elasticity of the spring 240 can facilitate the limiting and the displacement, and prevent the two ends of the bolt from getting stuck. The electric push rod 131 drives the top block 132 to move, which facilitates the pushing of the formed bolt and facilitates demolding. By rotating the rotating block, the bidirectional lead screw 211 is driven to rotate, so that the two lead screw nut pairs 212 and the two L-shaped support plates 220 move closer or further apart, which facilitates the positioning of bolts of different lengths and improves the practicality of the device.
