Description

Technical Field

[0001] The utility model relates to a rolling piece cutting tool. Background Art

[0002] A roller press is a device or component used to apply roller pressure or extrusion force. It is usually composed of one or more rollers or drums, and can apply continuous pressure to the surface of the material or workpiece to achieve processes such as extrusion, pressing, flattening, and embossing.

[0003] Rolled parts are widely used in various industrial fields and processes, including metal processing, plastic processing, paper processing, printing, coating, etc. Their functions include flattening surfaces, changing the shape of materials, increasing the density of materials, improving surface quality, and achieving coating or printing.

[0004] In the traditional roll-formed part cutting process, a cutting punch fixed to the upper die is typically used to separate the rolled workpiece into the front and rear sections, generating waste at the joint. This waste falls downward and requires continuous collection using a chute tooling. However, this can easily clog the cutting edge, damaging the die and increasing investment costs. Furthermore, the large amount of waste and residue negatively impacts costs and production efficiency. Therefore, a roll-formed part cutting tooling has been proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a roll-pressed part cutting tool to solve the problems in the above background technology that in the traditional roll-pressed part cutting process, waste materials easily clog the cutting edge, damage the mold, and the investment cost is high.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a rolling part cutting tool, comprising a carrier frame, the carrier frame comprising an upper support plate and a lower support plate, the upper support plate and the lower support plate are connected by a bearing column,

[0007] The upper part of the carrier is provided with a power assembly, the output end of the power assembly is connected to a die-cutting assembly for cutting the rolling piece, and the carrier is provided with a reset assembly at the die-cutting assembly.

[0012] The fixed template is provided with a passage for the upper inserting knife to be inserted directly below the upper inserting knife;

[0013] The fixed template is located on both sides of the cutting mold core and is provided with guide plates, and the guide plates are arranged diagonally, and the guide plate located on the upper part is located on the side of the cutting mold core away from the upper inserting knife.

[0014] Preferably, a plug-in plate for introducing a rolling piece is provided on one side of the fixed template, and a through groove cooperating with the rolling piece is provided in the middle of the plug-in plate and the cutting die core.

[0015] Preferably, the reset assembly includes a reset cover plate, a retaining plate is provided on one side of the reset cover plate, a channel is opened at the retaining plate, a connecting rod is provided inside the channel, and the side of the connecting rod away from the retaining plate is connected to the force plate through an extrusion plate, and the shape of the force plate is trapezoidal.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model can realize efficient cutting of rolled parts by providing a power component and a die-cutting component. The power component outputs power to the die-cutting component position in a directional manner, ensuring the accuracy and stability of the cutting process.

[0021] The waste and slag generated in the traditional cutting process can easily clog the cutting edge and damage the mold. However, this tooling can effectively collect waste by setting a fixed template and guide plate, preventing waste and slag from clogging the cutting edge and protecting the mold, thereby improving the waste processing and collection effect.

[0022] The design of the guide assembly and guide plate in the tooling ensures that the rolled parts are correctly positioned and guided during the cutting process, thereby improving the cutting process.

A connecting plate 203 is provided above the power cylinder 201 to connect the power cylinder 201 to external equipment through the connecting plate 203.

[0033] The output end of the power assembly 2 is connected to a die-cutting assembly 3 for cutting the rolled piece, and the die-cutting assembly 3 includes a fixed plate 301 arranged at the guide plate 501, and the lower part of the fixed plate 301 is connected to the upper inserting knife 302, and a fixed template 303 is arranged directly below the upper inserting knife 302, and a cutting core 304 is arranged in the middle of the fixed template 303, and a channel 305 for the upper inserting knife 302 is opened on the fixed template 303 directly below the upper inserting knife 302; the fixed template 303 is provided with guide plates 306 on both sides of the cutting core 304, and the guide plates 306 are arranged diagonally, and the upper guide plate 306 is located on the side of the cutting core 304 away from the upper inserting knife 302. A plug-in plate 307 for guiding the roller is located on one side of the fixed die plate 303. Both the plug-in plate 307 and the center of the cutting die core 304 are provided with a through slot 308 that mates with the roller. A channel is provided in the fixed die plate 303 for the connecting rod 403 to pass through, allowing the force-bearing plate 405 to drive the connecting rod through the channel. The cutting die core 304 is polygonal in shape, with beveled surfaces on all sides to ensure a close fit between the cutting die core 304, the guide plate 306, and the force-bearing plate 405.

[0034] The carrier frame 1 is provided with a reset assembly 4 located at the die-cutting assembly 3. The reset assembly 4 includes a reset cover plate, one side of which is provided with a retaining plate 401. The retaining plate 401 is provided with a channel 402. A connecting rod 403 is disposed within the channel 402. The side of the connecting rod 403 away from the retaining plate 401 is connected to a force-bearing plate 405 via an extrusion plate 404. The force-bearing plate 405 is trapezoidal in shape. A reset spring 406 is provided on the outer circumference of the connecting rod 403, located between the extrusion plate 404 and the retaining plate 401.

[0035] A guide assembly 5 is provided below the power assembly 2 to direct the power output of the power assembly 2 to the die-cutting assembly 3. The guide assembly 5 includes a guide plate 501 located at the output end of the ejector 202. A guide rod 502 is connected to one side of the guide plate 501, and the guide rod 502 is provided through the upper support plate 101.

[0036] The working principle of the roller cutting tool provided by the utility model is as follows: when in use, the cylinder is connected to the external equipment through the connecting plate 203,

[0037] The rolling piece is inserted into the through slot 308 of the cutting die core 304 through the plug-in plate 307. At this time, the control cylinder pushes out the ejector rod 202, driving the upper inserting knife 302 to move downward. At the same time, it moves linearly downward under the guidance of the guide mechanism.

[0038] The upper inserting knife 302 fits the inclined surface of the cutting core 304, driving the cutting core 304 to move along the two sets of guide plates 306, so that the plug-in plate 307 and the cutting core 304 are misaligned, and then the rolled part is cut off;

[0039] At the same time, the cut-off mold core 304 squeezes the force-bearing plate 405 at the bottom, and the force-bearing plate 405 squeezes the return spring 406 located on the periphery of the connecting rod 403 through the extrusion plate 404, and the return spring 406 contracts under the force.

[0040] When the fixed plate 301 is pulled back by the cylinder, the upper inserting knife 302 also moves back and away from the cutting die core 304. At this time, the return spring 406 is weakened and elastically elongates, driving the force-bearing plate 405 to return to its original position. At this time, the cutting die core 304 is pushed back by the elastic force of the return mechanism and returns to its original position. The above steps can be repeated for repeated operations.

[0041] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
