Abstract
The utility model discloses a backing plate of a rubber punching sheet forming test piece, which comprises a backing plate whole, magnetic beads and a square frame, wherein the backing plate whole is divided into two layers, the backing plate whole comprises a rubber layer and a plastic layer, the plastic layer is arranged at the lower part of the rubber layer, the square frame is arranged at the upper part of the plastic layer, and the magnetic beads are arranged at the lower part of the plastic layer. According to the utility model, by utilizing the characteristic that the rubber hardness is lower than that of plastic and wood boards, the loss of the cutting edge of the cutter is reduced when the cutter contacts the rubber layer. The backing plate is integral, the local rubber contacting the cutter is replaceable, the local rubber is worn, and the whole backing plate is not needed to be replaced. The magnet is embedded in the lower part of the backing plate and attracts the metal in the lower part of the punching machine, so that the backing plate is fixed.
Description
Technical Field
The utility model relates to a rubber backing plate technology, in particular to a backing plate of a rubber punching sheet forming test piece.
Background
Typically, test pieces for rubber testing are made by cutting with a cutter on a rubber sheet molding machine, and the test pieces are placed on a flat backing plate. The cutter penetrates the test piece and is necessarily contacted with the base plate, and the base plate becomes a wearing part. The backing plate is usually made of plastic plates and wood plates, so that the loss of the materials is high, and the cutting edge of the cutting knife is also lost when the materials contact the cutting knife.
Aiming at the problems, the utility model provides a gasket of a rubber punching sheet forming test piece for reducing the loss of the cutting edge of a cutter.
Disclosure of Invention
The utility model provides a gasket of a rubber punching sheet forming test piece for reducing the loss of a cutting edge of a cutting knife.
The utility model aims to provide a backing plate of a rubber punching sheet forming test piece, which comprises a backing plate whole, magnetic beads and a square frame, wherein the backing plate whole is divided into two layers, the backing plate whole comprises a rubber layer and a plastic layer, the plastic layer is arranged at the lower part of the rubber layer, the square frame is arranged at the upper part of the plastic layer, and the magnetic beads are arranged at the lower part of the plastic layer.
Further, the rubber layer is divided into four rubber gaskets, and the rubber gaskets are arranged in the square frame.
Further, the number of the magnetic beads is five.
Furthermore, the frame of the square frame is composed of an outer sleeve frame and an inner sleeve frame, and the inside of the square frame is hollow.
The utility model has the following advantages: according to the utility model, by utilizing the characteristic that the rubber hardness is lower than that of plastic and wood boards, the loss of the cutting edge of the cutter is reduced when the cutter contacts the rubber layer. The backing plate is integral, the local rubber contacting the cutter is replaceable, the local rubber is worn, and the whole backing plate is not needed to be replaced. The magnet is embedded in the lower part of the backing plate and attracts the metal in the lower part of the punching machine, so that the backing plate is fixed.

In the figure: 1. a rubber layer; 2. a plastic layer; 3. a rubber gasket; 4. magnetic beads; 5. an outer sleeve frame, 6 and an inner sleeve frame.
Detailed Description
The utility model provides a backing plate of a rubber punching sheet forming test piece, which comprises a backing plate whole, magnetic beads 4 and a square frame 5, wherein the backing plate whole is divided into two layers, the backing plate whole comprises a rubber layer 1 and a plastic layer 2, the plastic layer 2 is arranged at the lower part of the rubber layer 1, the square frame is arranged at the upper part of the plastic layer 2, and the magnetic beads 4 are arranged at the lower part 2 of the plastic layer.
In this embodiment, the rubber layer 1 is divided into four rubber gaskets 3, and the rubber gaskets 3 are all arranged in the frame 5.
In this embodiment, the number of the magnetic beads 4 is five.
In this embodiment, the frame of the square frame is composed of an outer casing 5 and an inner casing 6, and the square frame is hollow.
In this embodiment, the frame is provided to be extendable and retractable, so that the frame can be provided on the pad plates having different sizes when in use.
In this embodiment, when in use, the outer sleeve frame is slid outwards, so that the overall length and width of the frame are increased, and when the frame needs to be contracted, the inner sleeve frame is pushed inwards, so that the overall length is shortened.
In this embodiment, by integrally setting the backing plate as the upper rubber layer 1, the lower plastic layer 2 and the upper rubber layer 1 are replaceable, after the single rubber gasket 3 is worn out, only the rubber gasket 3 can be replaced or not replaced, when all the rubber gaskets 3 are worn out, the rubber gaskets 3 can be replaced together, and the upper rubber layer 1 is not hardened basically, but is supported by the lower plastic layer 2, the working state is not easy to sink, and the cutting edge of the cutter is not damaged.
In this embodiment, the magnetic beads 4 are embedded in the plastic layer 2, so that the base plate is fixed during use.
Although specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, it should not be construed as limiting the scope of protection of the present patent. Various modifications and variations which may be made by those skilled in the art without the creative effort are within the scope of the patent described in the claims.
