Abstract
The utility model relates to a push-and-pull rod device for an electronic torch melting furnace, which comprises a push rod, a cushion block and pins, wherein, the upper part of the push rod is provided with a cylinder with a dovetail groove; a pin hole which is perpendicular to the shaft line of the dovetail groove is arranged on the dovetail groove; the lower part of the cushion block is a dovetail shape which is matched with the dovetail groove of the push rod; a pin hole which is perpendicular to the shaft line of the dovetail is arranged on the dovetail; the size of the pin hole is the same as the size of the pin hole on the dovetail groove; the side of the pin is matched with the size of the pin holes on the push rod and the cushion block; the pins are inlaid in the pin holes of the push rod and the cushion block to be connected with the dovetail groove and the dovetail. The utility model solves the phenomenon of the frequent breaking occurrence of the push rod and the cushion block; therefore, the phenomena of the unevenness of smelting materials and smelting interruption. The utility model has the advantages of the improvement of product quality and the consumption reduction of the original auxiliary materials.
Description
Technical field
The utility model relates to a kind of electron beam furnace pull bar device.
Background technology
At present, the drawing mechanism of small-power electronics bundle smelting furnace mostly adopts rectilinear push-pull device at fixed, and this device comprises push rod, cushion block and pin.Push rod top is circular sleeve.And have a pin-and-hole, cushion block be one the band pin-and-hole boss, push rod is connected by pin with cushion block.When discharging; push rod is rotating and is moving downward; drive melting material on cushion block and the cushion block to bottom offset by pin; when the high metal of melting fusing point; the temperature of pin is subjected to the influence of high temperature, also often reaches 1000 ℃, and pin originally experience stress and shearing stress; thereby usually can make the pin fracture, cause melting interruption and melting material problem of non-uniform.
Summary of the invention
The purpose of this utility model is that the pin for the above-mentioned existence that overcomes electron beam furnace ruptures to cause to production and interrupts and the uneven problem of melting material and propose a kind of electron beam furnace pull bar device.
A kind of electron beam furnace pull bar device is characterized in that this device comprises:
Push rod-its top is the cylinder that has dovetail groove, and the pin-and-hole perpendicular with its axis arranged on dovetail groove;
Cushion block-its underpart has on the dovetail and the perpendicular pin-and-hole of its axis for the swallow-tail form that the dovetail groove with push rod matches, and this pin-and-hole size is consistent with the pin-and-hole size on the dovetail groove;
Pin-its size cooperates with pin-and-hole size on push rod and the cushion block, is embedded in the pin-and-hole of push rod and cushion block to be connected dovetail groove and dovetail.
Owing to taked technique scheme, the utility model has successfully solved electron beam furnace pin fracture and the interruption of the melting that causes and problem of non-uniform of melting material in producing fusion process, thereby improved the quality of product, reduced the consumption of supplementary material.

The specific embodiment
A kind of electron beam furnace pull bar device, it is characterized in that this device comprises: its top of push rod 3-is the cylinder that has dovetail groove, is provided with thereon and the perpendicular pin-and-hole of dovetail groove axis; Cushion block 1-its underpart for and the swallow-tail form that matches of the dovetail groove on push rod top, the assembling that matches with the dovetail groove on push rod top of its dovetail is provided with pin-and-hole axis and the corresponding to pin-and-hole of size on its axis and size and the push rod in its dovetail bottom; Its size of pin 2-matches with pin-and-hole size on push rod and the cushion block, inlays in the pin-and-hole of push rod and cushion block, connects dovetail groove and dovetail, stops the relative slip between them.Because push rod and cushion block adopt dovetail wedge type connected mode, and adopt pin prevent slip between throw-out lever and the cushion block, push rod rotates when moving downward like this, make push rod and cushion block to contact lifting surface area big, be difficult for taking place fracture accident, thereby guarantee normally carrying out of melting.
