Description

Vertical shaping machines for shaping bushes with flanges

technical field

The present invention relates to shaping machines, in particular to a vertical shaping machine for shaping sleeves with flanges used for processing sliding bearings.

Background technique

Now the output of sliding bearings in the market is increasing rapidly, and sliding bearings are divided into straight-through bushings, bushings with flanges, gaskets, sliders, etc. from their structural forms. Due to the compact structure of sliding bearings, strong load capacity, low manufacturing cost, simple manufacturing process, and the advent of various new materials in recent years, the advantages of sliding bearings will gradually appear, and they are more and more recognized by users. The output of shaft sleeves is increasing year by year. Improvement, the production method is gradually moving towards automated mass and efficient production. However, the shaping process of the flanged shaft sleeve still remains on the manual shaping now, the shaping mold is large, the labor intensity of manual operation is large, and the shaping efficiency is low.

Contents of the invention

The purpose of the present invention is to provide a vertical shaping machine for shaping bushes with flanges, which is simple in structure, easy to manufacture and use, and fast in shaping speed.

In order to achieve the above object, the technical solution of the present invention is: it includes a vertical underframe, on which is fixed a frame consisting of four uprights and the upper connecting plate and the lower connecting plate, which is characterized in that it is connected on the upper A hydraulic cylinder is installed on the board, and the hydraulic cylinder is connected with the hydraulic system. A movable plate is fixed on the head of the piston rod of the hydraulic cylinder, and a shaping mandrel is fixed in the middle of the movable plate. Two compression springs are respectively installed between the movable plate and the binder plate on both sides of the shaping mandrel. The lower end of the tie rod is connected with the pusher rod through a span to play a role in discharging the material. A shaping die is fixed on the lower connecting plate, and the center of the die hole of the shaping die is concentric with the center of the shaping mandrel.

The compression spring is a nitrogen gas spring.

A jack-up spring is installed at the joint between the lower end of the push rod and the span, and the jack-up spring bears against the shoulder on the push rod.

According to the above scheme designed for the vertical plastic machine with flange sleeve plastic, the piston rod of the hydraulic cylinder reciprocates under the control of the hydraulic system. The material plate presses the shaft sleeve to be shaped into the shaping die, and the shaping mandrel fixed on the movable plate performs shaping to the shaft sleeve to be pressed into the hole of the shaping die. When the piston rod is upwards, the push rod connected with the span pushes the reshaped bushing out of the shaping mold, takes out the reshaped bushing, and puts in the bushing to be reshaped at the same time, and enters the next cycle of shaping. 3 times. And the shaping machine can be incorporated into the shaping tooling in the sliding bearing production line, which has changed the current situation that the sliding bearing cannot be fully automated due to the manual shaping.

Detailed ways

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

Fig. 1 is a schematic structural diagram of a vertical shaping machine for shaping a shaft sleeve with a flange. As can be seen from the figure, it includes a vertical underframe 1, and the underframe 1 is fixed with a frame 5 composed of four columns 2, an upper connecting plate 3 and a lower connecting plate 4. On the upper connecting plate 3 A hydraulic cylinder 6 is installed, and the hydraulic cylinder 6 is connected with the hydraulic system. At the head of the piston rod 7 of the hydraulic cylinder 6, a movable plate 9 is fixed through a connecting plate 8, and a shaping mandrel 10 is fixed in the middle of the movable plate 9. Bolt 11 is connected with binder plate 12 below, and two nitrogen springs 13 are respectively installed between movable plate 9 and binder plate 12 on both sides of shaping mandrel 10, and shaping mandrel 10 passes binder plate 12, and Two pull rods 14 are fixed on the binder plates 12 on the left and right sides of the shaping mandrel 10, and the lower ends of the pull rods 14 are connected with the pusher rod 16 through the span 15 to play a discharging effect. On the lower connecting plate 4, a shaping die 17 is fixed, and the die hole center of the shaping die 17 is concentric with the center of the shaping mandrel 10. A jacking spring 18 is installed at the joint between the lower end of the push rod 16 and the span 15, and the jack spring 18 bears against the shoulder on the push rod 16. When the pull rod 14 and the span 15 moved downward, the push rod 16 Under the effect of the jack-up spring 18, it is still in the jack-up position, so that the axle sleeve 19 placed on the push rod 16 does not topple over.

During use, the piston rod 7 drives the movable plate 9 to reciprocate. When the piston rod 7 moved downward, the movable plate 9 also moved downward together, and the two nitrogen springs 13 on the movable plate 9 pushed the clamping plate 12 to move downward under the action of elastic force. After the axle sleeve 19 that needs shaping is pressed in the shaping mold 17, the movable plate 9 overcomes the elastic force of the nitrogen spring 13 and continues to move down, and drives the shaping mandrel 10 to implement shaping on the axle sleeve 19 as shown in Figure 2. When the piston rod 7 returns, the binder plate 12 still presses the axle sleeve 19 under the elastic force of the nitrogen spring 13, so as to prevent the shaping mandrel 10 from bringing the axle sleeve 19 out of the shaping die 17 during the return stroke. When the shaping mandrel 10 comes out of the shaft sleeve 19, the movable plate 9 drives the pressure plate 12 to move upward through the bolt 11, and at the same time, the pull rod 14 drives the span 15 to move upward, and the span 15 overcomes the elastic force of the jacking spring 18 to push the push rod 16 to move upward , push the reshaped shaft sleeve 19 out of the plastic mold 17 as shown in Figure 1, then remove the reshaped shaft sleeve 19, add the shaft sleeve 19 that needs to be reshaped, enter the next cycle, and perform a single cycle through the electrical switch, so reciprocating The shaft sleeve 19 is continuously shaped.
