Description

A tooling for processing T-shaped guide bars for tire molds

technical field

The utility model relates to a tool for processing T-shaped guide bars for tire moulds.

Background technique

In the tire mold processing, due to the connection of the mold combination, a strip-shaped T-bar tooling with a T-shaped cross-section needs to be used. The T-bar has a reference surface, and two surfaces need to be processed. The T-shaped bar is processed on a milling machine. When guiding the bar, it is necessary to find the center of the blank every time. The current practice is to first process a reference T-shaped bar. The reference T-shaped bar is processed with regular materials. First, a surface is milled as the reference surface, and then a L-shaped profile, use screws to install the L-shaped profile on the magnetic chuck, put the reference guide bar against the positioning angle of the L-shaped profile, the magnetic chuck sucks the reference T-shaped profile, find out the reference T profile After the center is processed, the machined surface is processed, and the subsequent T-bars do not need to find the machining center, and directly use the center given by the reference bar as the center of other T-bars to be processed. This method requires the suction cup to suck the T-shaped bar to be processed. If the force is too large during processing, the suction cup will not be able to suck, the T-shaped bar to be processed moves, and the tool and the workpiece may be damaged. Only one T-bar can be processed in one operation, and the efficiency is also low.

Utility model content

The purpose of the utility model is to provide a tooling for processing T-shaped guide bars for tire molds, which does not need to find the center every time, and has high efficiency.

The utility model adopts the following technical solutions:

A tooling for processing T-shaped guide bars for tire molds, including a rectangular steel plate, a plurality of rectangular grooves are opened on the steel plate, and the size of the rectangular grooves is matched with the blank of the T-shaped guide bar, which is suitable for T The machining blank of the shaped guide bar is put in, the four corners of the rectangular groove are respectively cleaned by the milling machine, and there are four round holes in the square groove, three of which are used for screw fixing, and one hole is Positioning pin hole, one side of the rectangular slot has an operation notch, which is convenient for the operator to put his hand into the bottom of the workpiece, and the entire steel plate can be sucked on the magnetic chuck for processing;

Further, it also includes a plurality of Z-shaped pressing plates. Through screws, the pressing plates can press the tooling on the workbench for processing, which can be used as an auxiliary pressing of the magnetic chuck, and can also be used to directly press the magnetic chuck when the magnetic chuck is not used. The tooling is pressed against the workbench.

The utility model is designed according to the needs of processing T-shaped bars for tire molds, and can put in multiple T-shaped bars at one time, which is not easy to shift during processing, not only improves the production efficiency, but also does not need to process the reference T-shaped bars.

Detailed ways:

Below in conjunction with accompanying drawing and specific embodiment, the utility model will be further described:

In Figures 1 and 2, the tooling 1 includes a rectangular steel plate with a plurality of rectangular grooves 11 (three rectangular grooves in the figure), the size of which is matched with the blank of the T-shaped guide bar, The processing blank suitable for the T-shaped guide bar is placed. The four corners of the rectangular groove are respectively equipped with clear corners 14 processed by the milling machine. There are four round holes in the square groove, of which three holes 13 are used for screw fixing. , a hole 12 is a positioning pin hole, and one side of the rectangular groove is provided with an operation gap 15, which is convenient for the operator to put his hand into the bottom of the workpiece, and the entire steel plate can be sucked on the suction cup for processing;

In Figure 3, there is a Z-shaped pressing plate 2. There are many Z-shaped pressing plates 2. Through screws, the pressing plate 2 can press the tooling 1 on the workbench for processing. When the suction cup is used, directly press the tooling on the workbench.

Figure 4 is a cross-sectional view of the T-shaped bar. A and B are the machined surfaces, and C is the reference surface. The processing requirements of the T-shaped bar are to process the A and B surfaces to ensure that the dimensions of H1-H2 meet the requirements.

Figure 5 is a schematic diagram of the original processing plan. The original processing plan requires an L-shaped backing die 4. The first step is to use a regular profile to process the reference T-shaped guide bar. The center of the base T-bar is used as the machining center of the milling machine. After that, the machining of the T-bar blank no longer needs to find the machining center, and only one T-bar can be processed at a time.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection of the utility model.
