Description

Transmission cross shaft device of press

Technical Field

The utility model relates to a press machine, in particular to a transmission cross shaft device of the press machine.

Background

The press (including punching machine and hydraulic press) is a universal press with exquisite structure. The press has the characteristics of wide application, high production efficiency and the like, and can be widely applied to cutting, punching, blanking, bending, riveting, forming and other processes. The metal is plastically deformed and broken by applying strong pressure to the metal blank to process the part. When the mechanical press works, the motor drives the large belt pulley (usually also used as a flywheel) through the V-belt, and drives the crank slide block mechanism through the gear pair and the clutch, so that the slide block and the male die linearly move downwards. After the forging and pressing work is completed, the mechanical press moves upwards on the slide block, the clutch is automatically released, and an automatic device on the crankshaft is connected to stop the slide block near the top dead center.

The existing simple press machine product comprises a cast iron base, a working pressing plate, a handle, a main shaft, a travel limit screw and the like, and the handle is rotated to drive the interlocking action. However, the handle and the shaft seat mounted on the base are easily damaged, even cracked or broken after long-term use. The two are generally connected by adopting a threaded connection mode, the structure is easy to loosen, and the cracking part is mostly arranged at the tail end boundary line of the external thread of the handle. The lack of a structural design for improving the service life of the product can also ensure the safety in the use process.

Detailed Description

As shown in fig. 1-4, a transmission cross shaft device of a press comprises a cross shaft handle 1 and a shaft head seat 2 which are fixedly connected, wherein a connecting hole 3 for connecting the cross shaft handle 1 is arranged on the shaft head seat 2, the wall of one end of the connecting hole 3 near the bottom of the hole is a threaded surface 4, the wall of one end of the connecting hole 3 near the hole opening is a smooth surface 5, the positions of the cross shaft handle 1 corresponding to the threaded surface 4 and the smooth surface 5 are respectively provided with a threaded section 6 and a smooth section 7, a through groove 8 is arranged on one side of the smooth section 7, which is opposite to the threaded section 6, and the through direction of the through groove 8 is radially parallel to the cross shaft handle 1. The threaded connection part is designed deeper, and a margin or a space is reserved for the main body part to go deep, so that the stress is balanced, and obvious cracks are not easy to generate rapidly under the action of bending stress at the junction. The through groove 8 is symmetrically arranged by taking the axis of the transverse shaft handle 1 as the center, the through groove 8 is designed to facilitate further fastening by using tools such as a spanner, the use stability is improved, and the through groove is more reliable than the traditional product. It should be noted that the through groove 8 is designed to be close to the axle head seat 2, so that the fastening effect is better.

The upper part of the shaft head seat 2 is in a truncated cone-shaped structure, and the connecting hole 3 is arranged on the inclined plane of the side wall of the upper part of the shaft head seat 2. The interlocking device is suitable for an operation environment, and is convenient for rotating the transverse shaft handle 1 so as to drive the interlocking action of the shaft head seat 2. The lower part of the shaft head seat 2 is of a step-shaped structure, the diameter of the shaft head seat 2 is sequentially reduced from top to bottom, the step-shaped structure is favorable for improving the structural installation stability, and the blocking structure can be designed in the axial direction to limit detachment during installation. And in particular, will not be described or limited in detail herein, depending upon the actual manufacturing requirements. The shaft head seat 2 is provided with the key groove 9 on the outer side wall of the lower part, so that key connection is realized, the key connection is one of the modes of limiting and fixing, the assembly is simple and reliable, and the design and use requirements are met.

In the description of the present utility model, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, merely to facilitate description of the present utility model and simplify the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model, while the basic principles, main features, and advantages of the present utility model are shown and described above, and it should be understood by those skilled in the art.
