[0002] The solder bar is a kind of product in soldering tin. The solder bar can be divided into two types: leaded solder bar and lead-free solder bar, both of which are used for the soldering of circuit boards. It is made of pure tin, with good wettability and fluidity, and is easy to solder. The solder joints are bright, plump, and there will be no bad phenomena such as false soldering. A sufficient amount of antioxidant elements are added, and the antioxidant ability is strong. It is made of pure tin, with less solder dross and reduced unnecessary waste.

[0003] During the production process of the lead-free solder bar, a cutting device is needed to perform cutting operations on it. When the lead-free solder bar is cut, the cutting surface of the lead-free solder bar will be in a burr state and needs to be shaped. However, the existing cutting device only has the function of cutting the lead-free solder bar and does not have the function of grinding and shaping the cutting surface of the lead-free solder bar. Therefore, corresponding improvements need to be made according to the above problems. Content of the Utility Model

Placing grooves are opened inside the placing seats, and sliding grooves are opened on both sides of the placing seats. Two groups of mounting plates are installed at one end of both sides of the placing seat, and electric push rods are installed on one side of each mounting plate. Sliders are slidably arranged inside the sliding grooves, and screw rods are movably screwed inside the sliders. One end of the screw rod is installed with a clamping plate through a bearing, and the other end of the screw rod is installed with a mounting disc. A hand-held rod is installed on one side of the mounting disc. A support column is installed at the inner position of the top end of the base, and a top plate is installed at the top end of the support column. An electric hydraulic rod is installed at the end position of the bottom end of the top plate, and a mounting frame is installed at the bottom end of the electric hydraulic rod.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] according to Figure 1 - Figure 2As shown in the figure, it includes a base 1. Installation columns 2 are installed at both sides near the top of the base 1, and placement seats 21 are installed at the tops of the installation columns 2. Placement grooves 22 are formed inside the placement seats 21, and sliding grooves 23 are formed on both sides of the placement seats 21. The placement grooves 22 penetrate through the interior of the placement seats 21, and the sliding grooves 23 penetrate through the inner walls on both sides of the placement seats 21. The placement grooves 22 and the sliding grooves 23 are communicated with each other. Two groups of mounting plates 24 are installed at both sides near one end of the placement seats 21, and electric push rods 25 are installed on one side of each mounting plate 24.

[0018] Sliders 3 are slidably arranged inside the sliding grooves 23, and screw rods 31 are movably screwed inside the sliders 3. One end of each screw rod 31 is installed with a clamping plate 32 through a bearing, and the other end of each screw rod 31 is installed with a mounting disc 33. The number of clamping plates 32 is four. The four clamping plates 32 are all arranged inside the placement groove 22, and the shapes of the four clamping plates 32 are all circular. A hand-held rod 34 is installed on one side of the mounting disc 33. One end of the slider 3 near the side of the mounting disc 33 is installed with a connecting plate 35, and one side of the connecting plate 35 is installed with one end of the two electric push rods 25.

[0019] A support column 4 is installed at the position near the inner side of the top of the base 1, and a top plate 41 is installed at the top of the support column 4. An electric hydraulic rod 42 is installed at the position near the end of the bottom of the top plate 41, and a mounting frame 43 is installed at the bottom of the electric hydraulic rod 42. A through hole is formed in the inner wall on one side of the mounting frame 43 near the transmission shaft, and one end of the transmission shaft penetrates through the inner wall on one side of the mounting frame 43 through the through hole. The other end of the transmission shaft is installed with the other inner wall of the mounting frame 43 through a bearing. The shape of the mounting frame 43 is in a shape of a capital C, and a cutting and grinding knife 45 is placed at the position between the inner walls on both sides of the mounting frame 43. A motor 44 is installed on one side of the mounting frame 43, and the output end of the motor 44 is installed with a cutting and grinding knife 45 through the transmission shaft.

[0020] During use, the operator can place the lead-free solder bar horizontally inside the two sets of placement seats 21, and make the two ends of the lead-free solder bar respectively lap inside the corresponding placement grooves 22. After that, the operator can rotate the corresponding mounting plate 33 and the corresponding screw 31 through the four sets of handheld rods 34, so that the corresponding clamping plates 32 can move towards the lead-free solder bar respectively, so that the inner surfaces of the clamping plates 32 can be closely attached to one side surface of the lead-free solder bar, so that both ends of the lead-free solder bar can be fixed. After that, the operator can start the electric hydraulic rod 42, so that under the operation of the electric hydraulic rod 42, the mounting frame 43 can move downward. At the same time, the motor 44 can be started, so that the cutting and grinding knife 45 can rotate at a high speed under the operation of the motor 44. When the cutting and grinding knife 45 contacts the lead-free solder bar, the lead-free solder bar can be cut. When the lead-free solder bar is completely cut off, since the two ends of the lead-free solder bar are respectively clamped and fixed by the corresponding two sets of clamping plates 32, the lead-free solder bar will not fall. At this time, the cutting and grinding knife 45 continues to rotate at a high speed, so that the cutting surfaces of the two lead-free solder bars can be polished and shaped. When the polishing operation is completed, the cutting and grinding knife 45 can be moved upward to the initial height through the electric hydraulic rod 42, and the motor 44 can be turned off. At this time, the electric push rod 25 can be started, so that under the operation of the electric push rod 25, the connecting plate 35 can move towards one side direction accordingly, so that the sliders 3 can move correspondingly inside the corresponding sliding grooves 23 respectively, so that the two sets of clamping plates 32 and the lead-free solder bar clamped and fixed by the two sets of clamping plates 32 move correspondingly together, so that the end of the lead-free solder bar far from the cutting and grinding knife 45 can move out of the inside of the placement groove 22. Finally, the screw 31 can be moved in the reverse direction, so that the inner surface of the clamping plate 32 can be far from one side surface of the lead-free solder bar. At this time, the lead-free solder bar can be taken out of the inside of the placement groove 22, so as to avoid contacting the cutting and grinding knife 45 when taking out from the end of the lead-free solder bar close to the cutting and grinding knife 45, thus causing unnecessary injuries.

[0021] 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 principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
