Description

Spring painting device

technical field

The invention relates to a painting device, in particular to a spring painting device.

Background technique

The hot press machine is the main equipment in the spring processing process. By heating and keeping the spring warm, the spring is compressed at high temperature, and the spring is rapidly cooled under the spring compression state. Painting on the spring is a special requirement of the engine manufacturer for the spring supplier. The purpose is to identify the supplier. Now there are two main methods of spring painting: manual painting and machine painting. At present, spring painting and hot pressing are two processes in the spring processing process, first painting and then hot pressing.

And existing spring painting device generally all has only one painting head, and work efficiency is lower.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a spring painting device, with double paint heads, high painting efficiency; on the other hand, the painting device can be installed on a hot press to Realize the one-time completion of spring painting and hot pressing.

According to the technical solution provided by the present invention, the spring painting device includes a frame, a horizontally moving cylinder and a guide rail are installed on the upper end of the frame, a slider is arranged on the piston rod of the horizontally moving cylinder, and the slider is arranged on the guide rail, and can Move back and forth along the guide rail; the slider is fixedly connected with the painting cylinder and the paint scraping cylinder, and a paint plate and a paint scraping board are arranged at the end of the piston rod of the paint scraping cylinder. The painting cylinder is a double piston rod cylinder. The piston rod end of the cylinder is connected with two painting heads; a paint plate is installed under the paint scraping cylinder and the paint cylinder, one end of the paint plate is provided with a paint tank, and the other end of the paint plate is a paint plane.

A sensor that can sense the distance between the spring and the paint head is installed on the frame at one side of the paint head.

The present invention has the following advantages: (1) The painting device of the present invention has double painting heads, and the painting efficiency of the spring is relatively high; (2) The painting device of the present invention can be installed on a strong press, and the Painting and hot pressing are completed at one time, which reduces the processing steps of the spring and improves the quality of the spring processing.

Detailed ways

The present invention will be further described below in conjunction with specific drawings.

As shown in Figures 1 to 2: the spring painting device includes a paint board 1, a paint scraper 2, a paint board 3, a paint scraper cylinder 4, a frame 5, a horizontal moving cylinder 6, a guide rail 7, a paint Cylinder 8, sensor 9, paint head 10, slider 11, paint tank 12, paint plane 13, etc.

As shown in Fig. 1 and Fig. 2, the present invention includes a frame 5, a horizontal movement cylinder 6 and a guide rail 7 are installed on the frame 5 upper end, a slide block 11 is arranged on the piston rod of the horizontal movement cylinder 6, and the slide block 11 is arranged on the guide rail 7 and can move back and forth along the guide rail 7; the slider 11 is fixedly connected with the painting cylinder 8 and the paint scraping cylinder 4, and the paint scraping plate 3 and the paint scraping plate 2 are arranged at the end of the piston rod of the paint scraping cylinder 4. The paint cylinder 8 is a double-piston rod cylinder, and the piston rod end of the paint cylinder 8 is connected with two paint heads 10; One end is provided with a paint tank 12, and the other end of the paint board 1 is a paint plane 13; when working, the piston rod of the horizontally moving cylinder 6 moves to drive the slider 11 to move horizontally along the guide rail 7, so that the paint scraping cylinder 4 and The painting cylinder 8 also moves horizontally. When the paint scraping cylinder 4 is positioned above the paint tank 12, the piston rod of the paint scraping cylinder 4 stretches out, and the lacquered plate 3 is stained with paint; Above the paint plane 13, the paint on the band paint board 3 is stained on the paint plane 13; the paint scraping cylinder 4 moves back, and now the paint scraper 2 scrapes the paint on the paint plane 13 evenly; When the paint cylinder 8 moved to the top of the paint plane 13, the piston rod of the paint cylinder 8 stretched out. After the paint head 10 was stained with the paint on the paint plane 13, the paint cylinder 8 moved to the top of the spring, and the paint cylinder 8 The movable stopper rod stretches out, and the painting head 10 is pressed on the spring to paint the spring;

Since the outer diameters of the springs are different, in order to ensure that the springs will not be affected when the springs are painted, the distance between the induction spring and the paint head 10 is installed on the frame 5 on the paint head 10 side. When the paint head 10 is pressed against the spring, the sensor 9 outputs a signal to control the piston rod of the paint cylinder 8 to retract, so as to prevent the paint head 10 from pressing down too much, which will affect the size and quality of the spring.

The painting device of the present invention can be combined with the hot strong press, as shown in Figure 3 and Figure 4, the painting device 20 of the present invention is installed in the middle of the feeding mechanism 40 at one end of the hot strong press 30 , after the springs are arranged in sequence by the feeding mechanism 40, they are automatically painted with paint when passing through the painting device 20, and then transported to the hot and strong press 30 for hot and strong pressing, so as to realize painting and hot and strong pressing at one time, saving The spring processing process.
