Description

Riveting forming tool

Technical Field

The utility model belongs to the technical field of machining equipment, and particularly relates to a riveting forming tool.

Background

In the field of machine manufacturing, workpieces are connected with a plurality of tool modes, and a more traditional mode is that two connected areas are punched and riveted by using a rivet gun.

If being connected of cylinder and casing, the casing is the aluminium part, the cylinder is the steel part, it is integrative to connect both zonulae occludens, and there is certain intensity, casing and cylinder combination region need be sealed, and can bear the sealing connection under the certain pressure condition, adopt screw thread connection at present, can have certain intensity, casing and cylinder combination region also can realize sealed, but processing screw thread, the process is comparatively complicated, these two processes need be gone on respectively on forming machine, the riveter bed, lead to production efficiency low, the cost is higher, and the positioning error stack of product can influence the quality of product in the process.

Disclosure of Invention

The utility model aims to solve the problems of complex working procedures, high cost and poor product quality of the existing workpiece connection process such as screw thread connection, and provides a riveting forming tool.

In order to solve the technical problems, the utility model adopts the technical scheme that: the utility model provides a riveting forming frock, includes the bottom plate, its characterized in that: the bottom plate is provided with a guide pillar, the guide pillar is sleeved with a return spring, the top end of the guide pillar is provided with a guide sleeve and a top plate, and the inner surface of the top plate is provided with a riveting head and a fixed seat;

the bottom plate is respectively provided with a limiting block and a bracket, a shell cylinder assembly is arranged on the limiting block and the bracket and comprises a shell and a cylinder, the limiting block is provided with the shell, the bracket is provided with the cylinder, the cylinder is sleeved and butted on the shell, and a butting area between the shell and the cylinder is in clearance fit;

the riveting device is characterized in that a press riveting blind hole is formed in the shell, the top plate and the fixing seat move downwards, the riveting head directly acts on the cylinder sleeve downwards, and the cylinder barrel and the shell are riveted to form and the riveting area is sealed in an interference fit mode.

The utility model has the beneficial effects that:

1. the riveting forming tool is suitable for mass production and low in cost because the guide post is arranged on the bottom plate and the return spring sleeved on the guide post, the top plate is arranged on the guide post, the downward movement of the top plate enables the rivet head and the fixing seat arranged on the top plate to move downwards so as to complete the riveting forming process, the return spring enables the top plate to return upwards, and the top plate is riveted at one time.

2. According to the riveting forming tool, the butt joint area between the shell and the cylinder is in clearance fit, the limiting block and the supporting seat are arranged on the bottom plate and used for fixing the shell and the cylinder of the shell and cylinder assembly respectively, the limiting block is used for positioning the shell, the supporting seat is used for positioning the cylinder, the structure is simple, the positioning is accurate, the machining error is improved, and the product quality is high.

3. According to the riveting forming tool, the riveting blind holes are formed in the shell, the top plate, the fixing seat and the rivet head move downwards, the shell cylinder assembly is placed on the riveting tool after being sleeved, the rivet head directly acts on the cylinder sleeve under the action of the pneumatic press machine and directly aligns to the corresponding blind hole on the shell to be riveted, the cylinder and the shell blind holes are attached to and riveted into a whole, the riveting gap between the cylinder and the shell is forcibly deformed due to the butt joint area of the cylinder, the gap is removed to generate interference and sealing, certain rigidity is achieved, the one-step forming process is achieved, the production efficiency is high, and switching of processing equipment is not needed.

Detailed Description

For a better understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings.

Referring to fig. 1, 2, 3 and 4, the riveting forming tool is adopted in the process of connecting the workpiece shell 11 and the cylinder 12, wherein the shell 11 is an aluminum piece, the cylinder 12 is a steel piece, and the riveting forming tool is adopted.

Four guide posts 3 are fixedly installed on the bottom plate 9, a reset spring 5 is sleeved outside the guide posts 3, a guide sleeve 2 and a top plate 1 are installed at the top ends of the guide posts 3, a fixed seat 4 and a riveting head 6 are installed on the inner surface of the top plate 1, and a pneumatic press machine or a hydraulic press machine is installed on the top plate 1.
