Description

Small thompson press device {Mini thompson press device}

The present invention relates to a small Thomson press device, and more particularly, to a small Thomson press device in which the installation space is minimized and cutting of a bio material or a fiber material can be precisely made.

Thompson press is a type of press device that cuts and forms a work piece by a pressing action of the other side that moves a work piece placed on a fixed side.

In general, the Thompson press is used to cut thin materials such as paper or film, but recently there is a demand to use it for the development of biomaterials used for medical or textile purposes.

Conventional Thompson press was an equipment that occupied a large proportion of factory space as the driving equipment was composed of large size for mass production and production of large products, but as described above, recently, materials for small production or research and development such as biomaterials and fibers. In order to play the role of cutting, there is a large demand for miniaturized products.

In order to meet these demands, a small product has been developed that is configured as a cam-type driving device inside the housing and operates well using the generally supplied power, but can be installed on a table in an office or laboratory or in a narrow space.

However, these products are made for simple use, and in the case of products for small quantity production or research and development, the shape of the cutting knife or the workpiece applied to it is not uniform, so it is difficult to set the exact position for each shape and precise cutting work. There was a side where this couldn't be done.

To explain in detail, in the case of small-scale production or research and development products, the shape may be different for each processed object. In general, it does not have a structure to fix these various shapes, so the processed object is properly placed in a position corresponding to the cutting knife. It is placed and pressed.

In this case, in the end, it is forced to perform press processing around the widest surface of the workpiece, resulting in a large number of workpieces being lost after the primary press processing, and inaccurate flow due to the flow of the unfixed workpiece. There is a high probability that a cut will occur.

In particular, in the case of biomaterials, since the workpiece is made of very expensive materials, it is necessary to minimize materials consumed after cutting such as scrap. There is an urgent need for development of Korea.

The present invention is invented to solve the above problems, and is easily applied to a variable shape of a workpiece to be fixed, and to provide a compact Thompson press device that allows press processing at a precise location and minimizes the installation space. There is a purpose.

The object of the present invention is not limited to the above-mentioned object, and other objects not mentioned will be clearly understood from the following description.

In the Thomson press apparatus according to the present invention for achieving the above object, a sliding portion is inserted between an upper pressing portion and a lower pressing portion of the housing portion to be press-processed, wherein the sliding portion includes: a fixed plate; A rotating plate installed opposite to the fixed plate and having a cutting knife provided while rotating on one side thereof; And a connecting shaft to which the rotating plate and the fixed plate are connected.

In addition, it is a technical feature that a fixing tool that is movable in a width and length direction is further provided on the surface of the fixing plate so that the work piece is fixed.

In addition, the rotating plate is made of a transparent synthetic resin material, it is characterized in that a plurality of through-holes are formed in the position where the cutting knife is attached and formed.

In addition, the connection shaft is formed to be perpendicular to the fixing plate and the rotating plate, it is characterized in that the buffer pin is provided.

The present invention by the above configuration can expect the following effects.

As the conventional Thompson press is composed of large equipment and requires a large installation space, a separate factory facility must be provided, but the small Thompson press can be installed on a desk in a laboratory or office, and can also be installed with power that is normally supplied. It can be movable, allowing for flexible installation.

The position of the fixture can be variably deformed even in various shapes of the workpiece, so precise press processing can be performed by firmly fixing the workpiece, and processing at the correct position can eventually maximize the use of the workpiece. It can bring about reduction of the cost required for this.

In the case of biomaterials, since the surface is often made of a moist material, it is adsorbed to the cutting knife after press processing, so it takes additional work to separate it, but it is easily removed through the through hole provided in the rotating means provided with the cutting knife It becomes possible.

In particular, in the case of biomaterials, since the cutting of the workpiece is often small, the process of separating it after cutting is often difficult, and the problem can be solved with a simple structure.

The sliding part where the work piece is located is secured with a space by the buffer pin, so that the user who seats and separates the work piece can easily contact it, which in turn prevents the occurrence of safety accidents such as constriction. It works.

It is a block diagram showing a rotating plate and a cutting knife of a press device.

A small Thompson press device according to a preferred embodiment of the present invention is a general Thompson consisting of a housing part 10, an upper pressing part 20, a lower pressing part 30, and a sliding part 40, as shown in FIG. It can be configured as a press device.

Before looking at the unique technical features of each configuration, let's take a look at a typical Thomson press configuration and how it works.

The Thompson press may be composed of a housing unit 10, an upper pressing unit 20, a lower pressing unit 30, and a sliding unit 40.

The housing unit 10 is formed with a space in which the entire configuration of the Thompson press can be provided, and the upper pressing unit 20 and the lower pressing unit 30 are provided therein, and the upper pressing unit 20 and the lower pressing unit ( A driving unit 11 for driving any one of 30) may be provided.

The housing unit 10 may be preferably configured in a closed type so that safety accidents due to the internal configuration can be prevented, but one side may be configured in an open state to facilitate insertion and discharge of the sliding unit 40. have.

A guide plate 13 for inserting and discharging the sliding part 40 may be extended in a horizontal direction in the opened portion of the housing part 10.

The sliding part 40 may be seated on the upper part of the guide plate 13, and the guide plate 13 itself slides and moves into the interior of the housing part 10, or the guide plate 13 is a fixed type and the sliding part 40 ) May move into the interior of the housing unit 10, and any other form may be possible.

The upper pressurization unit 20 and the lower pressurization unit 30 are formed to be spaced apart, and any one of the upper pressurization unit 20 and the lower pressurization unit 30 may be movable by the driving unit 11.

Preferably, the lower pressurization unit 30 moves upward by the driving unit 11 to press the fixed upper pressurization unit 20, so that the driving unit 11 is positioned under the housing unit 10. This allows you to obtain a stable layout of the entire configuration.

A sliding part 40 is located between the lower pressing part 30 and the upper pressing part 20, and the inside of the sliding part 40 is pressed by the pressure of the lower pressing part 30 to the upper pressing part 20. A work in which the workpiece is processed by the cutting knife 50 may be performed.

A driving unit 11 may be provided for the movement of the lower pressing unit 30. By means of a cam 15 having an eccentric rotation axis so that a Thompson press is provided in a small size and maintenance is easily achieved. The lower pressing part 30 may be moved.

By making the rotation radius of the cam 15 in contact with the lower surface of the lower pressing part 30, the rotational motion of the cam 15 is converted into a linear motion of the lower pressing part 30, so that the upper part of the lower pressing part 30 Movement to the pressing unit 20 is to be pulled.

The workpiece is positioned between the above-described lower pressurization unit 30 and the upper pressurization unit 20, but in a state located inside the sliding unit 40, the lower pressurization unit 30 from the outside of the housing unit 10 After being inserted between the upper pressurization unit 20 and the lower pressurization unit 30 or the upper pressurization unit 20, the sliding unit 40 is pressed by the movement of the lower pressurization unit 30, and the cutting is performed by the cutting knife 50. This is how a typical Thompson press works.

In each of the above-described general components, the sliding unit 40 having unique technical characteristics will be described.

The sliding part 40 may be composed of a fixed plate 100, a rotating plate 200, and a connection shaft 300.

First, look at the fixing plate 100.

The fixed plate 100 is a configuration capable of providing a base so that the workpiece is positioned, and does not mean a fixed position with limited movement, but means having a fixed position in the reference of the rotational operation of the rotating plate 200 to be described later. I can.

The fixing plate 100 may be located on the upper surface of the guide plate 13, and as described above, the guide plate 13 on which the fixing plate 100 is located may move into the interior of the housing 10, or the fixing plate 100 ), it may be possible to move into the interior of the housing unit 10 by sliding from the upper surface of the guide plate 13.

The fixing plate 100 is any material having strength that is not deformed by the pressure of the upper pressing unit 20 and the lower pressing unit 30 or damaged by the cutting knife 50 provided in the rotating plate 200 to be described later. It is possible, but it may be preferably made of a metal material or a synthetic resin material.

The work piece may be located on the upper surface of the fixing plate 100, and a fixture 110 may be further provided to fix the work piece.

The fixture 110 may serve to fix the workpiece by compressing one side of the workpiece to the fixing plate 100 so that the workpiece does not flow on the upper surface of the fixing plate 100.

The shape of the fixture 110 may be formed in a form in which two vertical pieces intersect, so that the movement in the vertical direction is prevented when the workpiece is fixed.

The principle that the fixture 110 is fixed to the fixing plate 100 is a method in which the fixing plate 100 is made of a metal material and the fixture 110 is made of a magnet, but a separate air inhaler is formed by forming a plurality of holes in the fixing plate 100. By using a method of fixing by forming a contact surface with the fixture 110 in a vacuum may also be used.

In the case of a workpiece to which the present invention is applied, it is made of a bio material or a fiber material, and is not affected by a magnet as a nonmagnetic material, and has voids, so it is not affected by air intake of the fixing plate 100, so that the fixture ( The workpiece may be fixed by the fixing force of 110) and the fixing plate 100.

Due to this configuration, since the fixture 110 can be fixed at any position of the fixing plate 100, a bar that can fix the workpiece despite various shapes of the workpiece, the bottom surface of the fixture 110 is a magnet It may be provided or made of a material without voids to achieve a vacuum.

Next, the rotating plate 200 is looked at.

The rotating plate 200 is configured to have a shape corresponding to the fixed plate 100, and may rotate with one side hinged to the connection shaft 300 to be described later.

A cutting knife 50 may be coupled to the rotating plate 200. In general, the cutting knife 50 may be seated in the center of the rotating plate 200.

The rotating plate 200 has a strength that is not deformed even when the upper pressing portion 20 and the lower pressing portion 30 are pressed, but may preferably be made of a transparent synthetic resin material.

For example, the rotating plate 200 can be made of a transparent acrylic material, and the operator visually checks whether the cutting knife 50 and the object to be processed are set at an appropriate position during press processing. For this, it may be desirable to be made of a transparent material.

One side of the rotating plate 200 coupled to the connection shaft 300 to be described later is hinged to be rotatable, but a head 210 inserted into the vertical groove 310 formed in the connection shaft 300 may be provided. .

Specifically, the head 210 may be configured to be vertically movable by being inserted into the vertical groove 310, but it may be hingedly coupled with the rotating plate 200 to enable the rotation of the rotating plate 200.

When there is no resistance, the hinge coupling between the rotating plate 200 and the head 210 may be preferably made such that the rotating plate 200 is tightened enough to maintain a parallel state with the fixing plate 100.

A plurality of through holes 230 may be formed in the rotating plate 200 around a portion to which the cutting knife 50 is attached.

In general, in the case of a biomaterial or a fiber material, the property of the material is moist, so it may have a property that is easily adsorbed to the cutting knife 50.

After the press processing of the workpiece is completed, the workpiece adsorbed by the cutting knife 50 must be removed by the operator, and the cutting knife 50 is located between the rotating plate 200 and the fixed plate 100. The operator may be troublesome to remove it from the lower part or to remove the rotating plate 200 by standing vertically.

The operator can remove the workpiece adsorbed by the cutting knife 50 through a plurality of through holes 230 from the upper surface of the rotating plate 200, which is by using a separate jig that penetrates the through holes 230 or It can be easily operated using an air blower, and in addition, it can also play a role of discharging partial pores that may occur during the press processing of the upper pressurization unit 20 and the lower pressurization unit 30.

Additionally, the through hole 230 may serve to allow the cutting knife 50 to be attached to the rotating plate 200.

Since the cutting knife 50 attached to the rotating plate 200 is generally smaller than the area of the rotating plate 200, conventionally, it is located in the center of the rotating plate 200 but adhered with an adhesive or the rotating plate 200 It was manufactured integrally with each cutting knife 50, it was necessary to be provided with a rotating plate 200.

Thus, in order for the cutting knife 50 to be easily detached from the rotating plate 200, a separate coupling hole that can be inserted into the through hole 230 on the surface of the cutting knife 50 in contact with the rotating plate 200 (51) can be provided.

The coupling hole 51 of the cutting knife 50 is fitted into the through hole 230, or the coupling hole 51 penetrated to the opposite side of the surface in contact with the cutting knife 50 is fixed by a method such as screwing. It may be possible to combine various cutting knives 50 to one rotating plate 200 may be possible.

In addition, since the through hole 230 may be provided in a wide area of the rotating plate 200, it may be possible for an operator to arbitrarily adjust the coupling position of the cutting knife 50.

Next, look at the connection shaft 300.

The connecting shaft 300 serves to connect the rotating plate 200 and the fixed plate 100, and when the rotating plate 200 and the fixed plate 100 are opposed to each other so as to be parallel, the rotating plate 200 and the fixed plate (100) It can be positioned in a vertical shape on all.

In detail, the connection shaft 300 is made in a form fixed to the fixing plate 100, and a vertical groove 310 into which the head 210 provided on the rotating plate 200 can be inserted and coupled may be provided. have.

A buffer pin 330 may be vertically inserted into the lower side of the vertical groove 310. The buffer pin 330 may serve to separate the rotating plate 200 from the fixing plate 100.

In detail, the head 210 receives a force spaced apart from the fixing plate 100 by the elastic force of the buffer pin 330, and as a result, the rotating plate 200 is spaced apart from the fixing plate 100 in a state where it is not pressed. You can keep it.

In general, when the rotating plate 200 and the fixed plate 100 are directly hinged without the same configuration as the connection shaft 300, the cutting knife 50 is positioned on the fixed plate 100 through the rotation of the rotating plate 200. When is in contact with the fixed workpiece, an incidence angle other than vertical may occur, which in turn leads to a horizontal force on the workpiece, so the workpiece may move and precise cutting may not be made.

By the buffer pin 330, the rotating plate 200 is in a parallel state while being spaced apart from the fixed plate 100, and the rotating plate 200 is pressed by the upper pressing part 20 and the lower pressing part 30. The cutting knife 50 of the fixed plate 100 can be vertically incident on the workpiece.

In addition, the separation between the rotating plate 200 and the fixing plate 100 by the buffer pins 330 may also prevent constriction of a part of the operator's body between the rotating plate 200 and the fixing plate 100.

The buffer pin 330 is configured in a pin shape, and a case 331 having a hole thereon is provided, and a protruding protrusion 333 protruding from the inside of the case 331 to the outside and a protruding protrusion from the inside of the case 331 ( It may be composed of an elastic body 335 giving elastic force to the 333.

The lower part of the case 331 is configured with a sealing stopper 337 that can be coupled by a thread, and the elastic body 335 is elastically supported by the sealing stopper 337 on one side inside the case 331, and the other side is a protruding protrusion. It may be elastically supported under the 333.

The protruding protrusion 333 may be composed of a protrusion 333a protruding outward on one side and an elastic groove 333b recessed into the other side so that the elastic body 335 is inserted.

Since the elastic body 335 is elastically supported in a state inserted into the elastic groove 333b, the protrusion of the protruding protrusion 333 is consistently made without shaking, and the length of the elastic body 335 can be maximized, thereby increasing the elastic force. It can be maximized.

The head 210 of the rotating plate 200 and the vertical grooves 310 of the connection shaft 300 may be provided in the same number, and the buffer pins 330 may be provided in the same number.

In the drawing, the buffer pin 330 and the vertical groove 310 are consciously expressed largely for clear confirmation, but the uppermost surface of the case 331 of the buffer pin 330 is formed at the same level as the upper surface of the fixing plate 100. It may be desirable, and due to this shape, only the protrusion 333a of the buffer pin 330 and the protruding protrusion 333 may appear when viewed horizontally with respect to the upper surface of the fixing plate 100.

When the head 210 of the rotating plate 200 is inserted into the vertical groove 310 of the connection shaft 300 and is pressed by the upper pressing unit 20 and the lower pressing unit 30, the head 210 Is descended along the vertical groove 310, and at this time, the elastic body 335 of the buffer pin 330 is compressed into the elastic groove 333b, so that the rotating plate 200 and the fixing plate 100 come into contact with each other. The workpiece is cut by the cutting knife 50.

After the pressing of the upper pressing part 20 and the lower pressing part 30 is released, the head 210 rises along the vertical groove 310 by the elastic force of the elastic body 335 of the buffer pin 330, The rotating plate 200 and the fixed plate 100 may be spaced apart.

The above-described embodiments are merely exemplary, and other embodiments variously modified therefrom are possible by those of ordinary skill in the art.
