Furthermore, the rolling body of the rolling guide rail is a cylinder.

Furthermore, the rolling body of the rolling guide rail is a ball.

The utility model discloses the beneficial effect who produces is: the utility model discloses the side guide rail that bears main processing power with the slip thread rolling layer board sets up to rolling guide, sets up bottom guide and top guide into sliding guide. In order to bear larger processing force, the area of the side guide rail is larger, the friction force can be greatly reduced after the rolling guide rail is used, and the bottom guide rail and the top guide rail which are mainly used for constraint action adopt sliding guide rails, so that the adjustment of the whole sliding thread rolling supporting plate becomes very simple, the energy is saved, and the working efficiency is improved.

Detailed Description

The first embodiment is as follows:

the embodiment is a thread rolling machine combining a supporting plate rolling friction and a sliding friction, and is shown in figures 1 and 2. The machine tool comprises a machine tool body 1, wherein a bottom guide rail 2 and a side guide rail 3 are arranged on the machine tool body 1, a sliding thread rolling supporting plate 4 capable of sliding on the bottom guide rail and the side guide rail is arranged on the bottom guide rail and the side guide rail, a top guide rail 5 is arranged on the upper portion of the sliding thread rolling supporting plate, the bottom guide rail and the top guide rail are sliding guide rails, the side guide rail is a rolling guide rail, or the top guide rail is a sliding guide rail, and the bottom guide rail and the side guide rail are rolling guide rails.

The thread rolling machine described in this embodiment has a sliding thread rolling die 6 and a fixed thread rolling die 7, as in the conventional thread rolling machine, between which is a workpiece 8, the sliding thread rolling die is fixed on a sliding thread rolling support plate, and the fixed thread rolling die is fixed on a bed, as shown in fig. 1.

The rolling body of the rolling guide rail can be a cylindrical rolling body because the side guide rail has a large area to bear large processing force. The height of the cylinder (the distance between the two end faces) can be close to the width of the guide rail, i.e. the area of the entire guide rail can be covered by a row of rolling bodies. This has the advantage that it can withstand large machining forces, but the accuracy of the rolling element manufacture is high and it is difficult to find a rolling element of the correct length (height), which most standard cylindrical rollers do not have. It is therefore possible to use a multi-row rolling element arrangement, i.e. to provide more than two rows of rolling elements on the side rail.

The bottom rail also carries a greater load and a greater friction and may therefore also be provided as a rolling rail to reduce friction. Also the bottom rail may be arranged with more than one row of rolling elements, as shown in fig. 2, with two rows of rolling elements.

The rolling bodies can be cylindrical or spherical. And the spherical rolling body is the most economic choice, and the cost of the rolling guide rail can be greatly reduced.

Example two:

this embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment with respect to the rolling elements. The rolling bodies of the rolling guide rail described in this embodiment are cylinders.

The rolling bodies described in this embodiment are cylindrical rolling bodies, and only one row of rolling bodies may be provided, or a plurality of rows of rolling bodies may be provided. When a row of rolling bodies is provided, the length (or height, i.e. the distance between the two end faces) of the rolling bodies should be close to the width of the guide rail, so that the row of rolling bodies can cover the entire bearing surface of the guide rail. If two rows of rolling bodies are adopted, the two rows of rolling bodies need to be respectively arranged on two sides of the bearing surface of the guide rail so as to generate stable bearing effect. When multiple rows of rolling elements are used, then several rows of rolling elements may be added between the two rows of rolling elements on both sides, as shown in fig. 3. Fig. 1 and 2 show the case where the side rail is a row of cylindrical rollers, and fig. 3 shows the case where the side rail is a four-row cylindrical rollers.

Example three:

this embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment with respect to the rolling elements. The rolling bodies of the rolling guide rail according to the present embodiment are balls, as shown in fig. 4. In fig. 4, the case of 5 rows of spherical rolling elements is shown.

The spherical rolling body is commonly called as a steel ball, is the most common rolling body, has mature process, high precision and low price, and is an ideal rolling element. The row installation can bear larger processing force, and the installation and the adjustment are relatively convenient.

Finally, it should be noted that the above is only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred arrangement, it should be understood by those skilled in the art that the technical solutions of the present invention (such as the power form of the thread rolling machine, each connection relationship, etc.) can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
