Description
Technical Field
The utility model relates to a forging and pressing equipment technical field, concretely relates to press knockout device.
Background
Forging is the combination of forging and stamping, and is a forming method for obtaining a product with a required shape and size by applying pressure to a blank by using a hammer head, an anvil block, a punch head or through a die of a forging and stamping machine to generate plastic deformation. The mould is often used in casting, forging, punching press production process, and the mechanism of beating is the mechanism of pushing out work piece or sheet material from the mould, and the lower most part of the knockout bar of current knockout device is cylindrical or annular generally, and under some special circumstances, can appear taking off the problem that the product is damaged because the atress area is little when expecting, influences product quality.
SUMMERY OF THE UTILITY MODEL
The utility model aims at above problem, provide a press knockout device, the pole of beating the material designs to be convenient for change, and the design of beating the stub bar becomes multiple shape, is favorable to increasing the lifting surface area when beating the material.
The utility model is realized in such a way that a pressing machine ramming device comprises a ramming cylinder which is arranged on a slide block through a connecting flange, wherein a piston rod is arranged in the ramming cylinder, and a guide sleeve is arranged between the inner lower part of the ramming cylinder and the piston rod; the method is characterized in that: the two sides of the lowest end of the piston rod are respectively provided with a connecting plate, the uppermost end of the knockout rod is also correspondingly provided with a connecting plate, and the connecting plate on the piston rod is connected with the connecting plate on the knockout rod through a bolt; the material beating head at the lowest part of the material beating rod consists of a semicircular part and an arc-shaped concave part.
Further, the pressing machine knockout device is characterized in that arc chamfers are arranged at two ends of the arc concave surface part.
Further, the pressing machine knockout device is characterized in that the width of the connecting plate is smaller than the pipe radius of the piston rod.
Further, the pressing machine ramming device is characterized in that the bottom surfaces of the semicircular part and the arc-shaped concave part are in the same plane.
The utility model discloses a knockout device, before the use, the staff is according to the product shape characteristics in the mould, and thickness degree, confirm the installation direction of knockout head, both selected semicircle portion and the concave facial orientation of arc, then will knockout the pole through the connecting plate, bolted connection is to the piston rod on, afterwards, the drive arrangement who starts the jar of knockout beats the material operation, can be to the product of special shape like this, and the position of easy damage, increase the lifting surface area of knockout head and mould as far as possible, avoid the damage of product, guarantee product quality.
The utility model has the advantages that: 1. the utility model discloses a knockout device can be according to the product shape characteristics in the mould and thickness degree, confirms the installation direction of beating the stub bar, can be to the product of special shape like this to and the position of damaging easily, increase the lifting surface area of beating stub bar and mould as far as possible, avoid the damage of product, guarantee product quality. 2. The knockout pin is convenient to replace, and the design impact force bearing capacity of the connecting plate is stronger, which is beneficial to increasing the service time of the knockout device.
