Fully automatic continuous extruding and continuous coating machine utilizing front-hinged locking shoe system

Abstract

The present invention relates to an equipment capable of making continuous extrusion and continuous cladding operation, in the concrete, it relates to a full-automatic continuous extruding and continuous cladding machine by using front-hinged shoe-locking system. It is characterized by that the extruding wheel is mounted on the bearing of machine frame, the shoe seat and shoe-locking arm are respectively fixed in the positioning hole of machine frame by means of jointed shaft, the shoe seat driver and shoe-locking arm driver are used for driving shoe seat and shoe-locking arm, and said jointed shaft is positioned is the front of said shoe seat.

Description

Technical field: [0001] The invention belongs to the field of metal plastic forming and relates to equipment for continuous extrusion and continuous cladding. Background technique: [0002] Existing oscillating shoe presses see figure 1 As shown, the extrusion wheel is installed on the frame and rotates with a fixed axis driven by power. The shoe seat is fixed on the machine frame by the lock shoe cylinder and the limit stop when the extrusion machine is working, so as to realize the production of continuous extrusion products. When the extruder is not in working condition, at first the handle of the lock shoe cylinder is manually pulled, and then the lock shoe cylinder swings around the hinge axis in the A direction to make room for the shoe seat to swing out. Then pull the shoe seat drive cylinder to make the shoe seat rotate around the hinge shaft, and make the shoe seat swing out along the B direction, then mold replacement or equipment maintenance can be carried out. ...

AI Technical Summary

Problems solved by technology

The disadvantages of this rear hinge lock shoe mechanism are:

[0003] 1. The shoe lock cylinder needs to be operated manually, which is labor-intensive and cannot be automated

[0004] 2. The drive cylinder of the shoe seat is set at the exit of the product, which brings a lot of inconvenience and safety hazards to the workers.

[0005] 3. When switching between extruding and cladding modes, it is very difficult to arrange and fix the shoe drive cylinder

[0006] 4. Due to the limitation of the structure, the required lock shoe force is large and the pressure is high

[0007] 5. The hinge shaft of the lock shoe cylinder is behind the shoe seat, and the frame must have an "ear" structure to fix the hinge shaft, so the frame needs a large blank, and the material cost is high

At the same time, the "ear"-shaped structure will bring inconvenience and safety hazards to the workers when replacing the cavity and mold, and the appearance of the equipment is not beautiful.

[0008] 6. The locking shoe mechanism itself does not constitute a closed force system. Excessive locking shoe force will be transmitted to the frame to cause deformation and affect the accuracy of the equipment

[0009] 7. The ratio of common parts for extrusion and cladding mode is low
