Description

TECHNICAL FIELD

[0001] The utility model relates to soldering tin strip production equipment technical field, specifically for a kind of automatic cutting device for producing soldering tin strip. BACKGROUND

[0002] In the process of metal parts processing, welding is often used, because the physical properties of soldering tin strip are very suitable for welding, so most of the welding equipment uses soldering tin strip as welding material.

[0003] In the process of soldering tin strip production, the soldering tin strip produced is generally cut, and the soldering tin strip is cut into a length suitable for use by using the cutting device, but when cutting the soldering tin strip, the soldering tin strip is generally pulled forward by a traction roller, but the traction effect of the traction roller is poor, and the length of the soldering tin strip cut each time cannot be accurately controlled, and the soldering tin strip is easily offset when being cut by the cutting knife, so manual adjustment is required, and the automation is low.

[0014] Compared with the prior art, the present invention provides an automatic cutting device for producing solder bars, which has the following advantages:

[0015] 1. This utility model, through the cooperation of a set of mounting blocks, rollers, transmission sliders, and cutting blades, allows for manual rotation of the adjusting handwheel at the start of production. This rotation drives the lead screw, causing the two second transmission sliders to move closer together. Consequently, the two mounting blocks move closer together, and the distance between the rollers mounted on the two mounting blocks is adapted to the width of the solder bar to be produced. This restricts the position of the solder bar and guides its movement, preventing positional deviation during the cutting process. A servo motor drives the threaded rod to rotate, causing the first transmission slider to slide along the sliding groove. Simultaneously, this causes the bottom electric telescopic rod and cutting blade to slide along the sliding groove, adjusting the distance between the cutting blade and the mounting blocks, thereby adjusting the cut length of the solder bar.

[0024] Please see Figures 1-4An automatic cutting device for producing solder bars includes a main body 1, four support columns 2 mounted on the bottom of the main body 1, a frame 3 arranged on the main body 1, a sliding groove 22 opened on the frame 3, a threaded rod 12 rotatably mounted in the sliding groove 22, a servo motor 13 arranged on one side of the frame 3, the threaded rod 12 mounted on the action output shaft of the servo motor 13, a first transmission slider 11 threadedly connected to the threaded rod 12, an electric telescopic rod 14 mounted on the bottom of the first transmission slider 11, an installation strip 15 connected to the bottom of the electric telescopic rod 14, a cutting blade 18 inserted into the installation strip 15, a transmission cavity 19 opened on the main body 1, a lead screw 20 rotatably mounted in the transmission cavity 19, two mutually symmetrical second transmission sliders 21 threadedly connected to the lead screw 20, an installation block 8 mounted on the top of the second transmission sliders 21, and a roller 9 rotatably mounted on the installation block 8.

[0025] By cooperating with the mounting blocks 8, rollers 9, transmission sliders, and cutting blades 18, at the start of production, manually rotating the adjusting handwheel 10 drives the lead screw 20 to rotate, causing the two second transmission sliders 21 to move closer together. This, in turn, brings the two mounting blocks 8 closer together, ensuring that the distance between the rollers 9 mounted on the two mounting blocks 8 matches the width of the solder bar to be produced. This restricts the position of the solder bar and guides its movement, preventing positional deviation during cutting. The servo motor 13 drives the threaded rod 12 to rotate, causing the first transmission slider 11 to slide along the sliding groove 22. Simultaneously, this causes the bottom electric telescopic rod 14 and the cutting blade 18 to slide along the sliding groove 22, adjusting the distance between the cutting blade 18 and the mounting blocks 8, thereby adjusting the cut length of the solder bar.

[0026] Specifically, in this embodiment, one end of the lead screw 20 passes through the main body 1 of the device and is connected to an adjusting handwheel 10, the outer surface of which is covered with a rubber anti-slip sleeve.

[0027] The rubber anti-slip sleeve ensures friction between the user's hand and the adjustment handwheel 10, and improves user comfort.

[0028] Specifically, in this embodiment, a guide groove 23 is provided on the device frame 3, and a connecting rod 24 is slidably arranged in the guide groove 23. The connecting rod 24 is installed on the first transmission slider 11, and a pointer 5 is connected to the end of the connecting rod 24 away from the first transmission slider 11.

[0029] Through the cooperation of the guide groove 23, connecting rod 24 and pointer 5, the connecting rod 24 can be driven to slide along the sliding groove 22 while the first transmission slider 11 slides along the sliding groove 22, thereby causing the pointer 5 to move horizontally.

[0030] Specifically, in this embodiment, a scale bar 6 is provided on the side of the device frame 3 near the pointer 5, and the scale bar 6 corresponds to the position of the pointer 5.

[0031] The scale bar 6 allows the operator to visually observe the distance the first transmission slider 11 moves within the sliding groove 22, thereby enabling precise adjustment of the cutting length of the solder bar by the cutting blade 18.

[0032] Specifically, in this embodiment, a T-shaped groove 16 is provided on the mounting strip 15, and a T-shaped strip 17 is slidably arranged in the T-shaped groove 16. The T-shaped strip 17 is located on the top of the cutting blade 18.

[0033] The T-slot 16 and T-strip 17 allow for easy insertion of the cutting blade 18 into the mounting strip 15 along the T-slot 16, and conversely, enable quick disassembly of the cutting blade 18.

[0034] Specifically, in this embodiment, the main body 1 of the device is provided with a feeding groove 7, which is inclined. The top opening is located at the middle of the top surface of the main body 1 directly below the cutting blade 18, and the side opening is provided with the side of the main body 1.

[0035] With the provided feeding trough 7, after the solder bar is cut, it can slide down from the feeding trough 7 to one side of the main body 1 under the influence of gravity, which makes it convenient for operators to collect the cut solder bar.

[0036] Specifically, in this embodiment, a stop block 4 is installed on the side of the device body 1 away from the mounting block 8 and the device frame 3, and the stop block 4 is arranged at the center line of the device body 1.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
