Description

A rubber expansion machine

technical field

The utility model relates to the field of mechanical processing and manufacturing, in particular to a rubber expansion machine.

Background technique

The processing of rubber is very extensive in the daily production and processing process, especially in today's growing mechanical processing, in many cases it is necessary to expand and then process rubber products, but due to the influence of rubber materials and other aspects, in daily In the process of rubber processing, the expansion of rubber is often due to the thicker rubber material and other factors, resulting in a large force consumption during expansion, which brings great inconvenience to production. In the past, it was all manual processing. Now the rubber expansion machine The expansion of rubber can be realized by machinery, which saves time and labor and improves work efficiency.

At present, the cylinder of the rubber expansion machine of conventional equipment is directly connected to the back chuck. In order to make the expansion process uniform, two cylinders are usually connected to the chuck through movable bolts. If the expansion force is too large, the expansion will not be smooth, which will easily cause the claws to break; if the set cylinder diameter is large, the force of the cylinder body and the force point of the chuck will be on a fixing screw during the expansion process, which will easily cause the screw to break and cause damage to the equipment.

Utility model content

In view of the above situation, the utility model provides a rubber expansion machine.

In order to achieve the above object, the utility model adopts the following technical solutions:

A rubber expansion machine, including expansion chuck, motion chuck, expansion jaws, movable rod, power cylinder and transmission rack connected with the cylinder rod of the power cylinder, the expansion chuck is linked and fixed on the equipment and connected with The moving chucks are connected, and the moving chuck is provided with a plurality of helical first slide grooves, and the expansion chuck is provided with a plurality of first grooves leading to the center of the circle along the radial direction of the expansion chuck. Two chutes, the movable rod is set in the first chute by bolts and can move in the first chute, the end of the movable rod at the center of the circle is fixed with an expansion claw perpendicular to the movable rod , the expansion claw can move along the second chute through the movable rod, the motion chuck is arranged on the transmission rack, and the side of the motion chuck is provided with a protrusion that matches the transmission rack. tooth.

Further, the number of the first chute, the second chute, the movable rod and the expansion claw is the same, all of which are four.

Further, the cylinder rod of the power cylinder is provided with a guide device, and the guide device is provided with a guide groove matching with the cylinder rod of the power cylinder.

Further, an expansion adjustment screw is provided at the end of the guide groove away from the power cylinder.

Beneficial effect:

The rubber expansion machine provided by the utility model makes the expansion movement smooth through the mutual parallel motion power transmission structure of the movement chuck and the rack, and solves the problem of the expansion claws and point force bolts breaking due to unsmooth expansion.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

The utility model provides a rubber expansion machine, which includes an expansion chuck 1, a motion chuck 2, an expansion jaw 3, a movable rod 4, a power cylinder 5 and a transmission rack 6 connected with the cylinder rod of the power cylinder. The disk 1 is linked and fixed on the equipment and connected with the moving chuck 2. The moving chuck 2 is provided with 4 spiral first chute 7, and the expansion chuck 1 is provided with 4 Leading to the second chute 8 arranged radially along the expansion chuck 1 leading to the center of the circle, the four movable rods 4 are arranged in the first chute 7 through bolts 9 and can move in the first chute 7, The end of one end of the movable rod 4 at the center of the circle is fixed with an expansion claw 3 perpendicular to the movable rod 4, and the expansion claw 3 can move along the second chute 8 through the movable rod 4, and the movement The chuck 2 is arranged on the transmission rack 6 , and the side of the moving chuck 2 is provided with convex teeth 10 matched with the transmission rack 6 .

The cylinder rod of the power cylinder 5 is provided with a guide device 11, the guide device 11 is provided with a guide groove 12 matched with the cylinder rod of the power cylinder 5, and the end of the guide groove 12 away from the power cylinder is provided with Expansion adjustment screw 13.

The working principle of the utility model is as follows: in the actual expansion process, the expansion jaws 3 at the ends of the four movable rods 4 are all at the center of the expansion chuck 1, and the rubber tube is first inserted into the expansion jaws 3 to ensure that all Expansion claws 3 are all in the inside of the rubber tube to be expanded, start the power cylinder 5, and the cylinder rod of the power cylinder 5 moves in the guide groove 12, driving the rotation of the motion chuck 2 meshed with the transmission rack 6. At this time, the movable rod 4 will move along the first chute 7 in a direction away from the center of the circle according to the rotation of the motion chuck 2, and drive the expansion claw 3 to move along the second chute in a direction away from the center of the circle, and the expansion claw 3 will expand. Rubber tube for expansion purposes. On the contrary, when the cylinder rod of the power cylinder 5 moves in the other direction in the guide groove 12, the expansion claw 3 returns to the initial state, and the expansion size of the expansion claw 3 can be adjusted in the guide groove by adjusting the adjustment screw 13. to adjust the position within.

For the limitation of the protection scope of the present utility model, those skilled in the art should understand that on the basis of the technical solution of the present utility model, various modifications or deformations that those skilled in the art can make without creative labor are still within the scope of the present utility model. within the scope of protection.
