Description
Technical field
The present invention relates to the make-up machine of polytetrafluoroethylsteel steel bar.
Background technology
Polytetrafluoroethylplastic plastic is a kind of engineering plastics of excellent performance, and it is good that it has self-lubricating property, and coefficient of friction is low, high-low temperature resistant, corrosion-resistant and good insulation performance performance and non-viscosity are widely used in machinery, electronics, oil, chemical industry, industries such as food, light industry.
Existing polytetrafluoroethylplastic plastic bar generally adopts hot pressing to extrude preparation.Existing bar hot pressing extrusion machine mainly is horizontal.As shown in Figure 1, extruder is made up of following several parts: hydraulic system 1, oil cylinder 2, hopper 6, fuselage 8, push rod 3 etc.This horizontal machine structure, the shortcoming of existence mainly contains following several respects: (1), yield poorly, and once can only release a bar, speed can not satisfy the customer order demand too slowly; (2), blanking is not smooth, is easy to occur stopping up the hopper phenomenon, makes the bar fracture of release; (3), the too high workman of the hopper labour intensity of feeding is big, blanking is inconvenient to be difficult for blanking; (4), machine take up room greatly many, and complex structure easily assembling not.
For this reason, Chinese invention patent application (application number: 200710067130.7 applyings date: 2007-01-31) disclose a kind of polytetrafluoroethylsteel steel bar hot pressing and extruded special hot pressing extrusion machine, comprise frame, fuselage, push rod, hopper, extruding pipe, described fuselage vertically is provided with, hopper is arranged on body upper, extruding pipe is arranged in the fuselage, and push rod is arranged on above the hopper and over against extruding pipe.This hot pressing extrusion machine is simple in structure, can be upper and lower floor install, solved the too high workman of the hopper big technical problem of labour intensity of feeding, blanking is convenient, is easy to blanking.But this device is because extruding pipe is welding is arranged in the fuselage, more whole fuselage need be unloaded in the mold exchange carrying out, and fuselage is very heavy often, is divided into up and down floor again and installs, so the trouble of mold exchange ten minutes more.
Summary of the invention
In order to solve the technical problem of the die change trouble that above-mentioned hot pressing extrusion machine exists, the purpose of this invention is to provide a kind of polytetrafluoroethylmolding molding pushing press of being convenient to change core rod, that this device has is simple in structure, implement characteristics easily.
In order to realize above-mentioned purpose, the present invention has adopted following technical scheme:
Be convenient to change the polytetrafluoroethylmolding molding pushing press of core rod, this pushing machine comprises frame, pressing device, batching dish and fuselage, and pressing device, batching dish and fuselage all are fixed on the frame, and pressing device is arranged on batching dish top, and the batching dish connects fuselage; Fuselage comprises core rod, core rod top board, bottom block, core rod location-plate and heating jacket; Described core rod location-plate is fixedly installed on the bottom block, and core rod location-plate and heating jacket link into an integrated entity by stay bolt, and core rod location-plate and heating jacket are provided with first installing hole that is interconnected; Described core rod top board is arranged on the below of batching dish, and the batching dish is provided with connector, and the top of core rod top board is arranged in the connector, and the core rod top board is provided with second installing hole; Described core rod is provided with nib, the outer ring of core rod is provided with positioning convex ring, the core rod of positioning convex ring bottom is arranged in first installing hole, and the core rod on positioning convex ring top is arranged in second installing hole, and described nib is communicated with the batching dish and the pushing plug on the pressing device.
As further improvement, above-mentioned core rod is many.As preferably, the diameter difference of the nib of many core rod.The core rod of employing plurality of specifications can be extruded the polytetrafluoroethylsteel steel bar of multiple diameter size in a pushing machine, improved the range of application of pushing machine, and the bar of having avoided producing different size needs the trouble that more mold exchange brought.
As further improvement, between above-mentioned core rod top board and core rod location-plate, be provided with the first cooling water pond, the first cooling water pond is set in the top of positioning convex ring.By being set, the first cooling water pond avoids the heat of bottom to pass to feeder making powder caking make powder when entering core rod, need keep more complete particle, be beneficial to blanking.
As further improvement, be arranged with the second cooling water pond in the outer ring of above-mentioned core rod location-plate.The purpose of the second cooling water pond is to avoid the high temperature of the heating jacket of below upwards to transmit.
As further improvement, above-mentioned pressing device comprises oil cylinder, slide plate chair, sliding sleeve and guide rail, slide plate chair is arranged on the guide rail by sliding sleeve, the upper end of slide plate chair is connected with the piston rod of oil cylinder, the slide plate chair below is provided with location-plate, location-plate is fixed by clamping plate, and described pushing plug is arranged on the location-plate.Above-mentioned structure provides a kind of pushing plug fixed form.
As further improvement, it is excessive that the upper end of above-mentioned nib is provided with circular arc chamfering.Circular arc chamfering helps the powder blanking.
The present invention is owing to adopted above-mentioned technical scheme, when needing more mold exchange, only need take off batching dish and core rod top board earlier, just can advance whole core rod taking-up and change, and do not need whole fuselage is taken off replacing, so just greatly facilitate the replacing of mould.Further, many core rod can adopt the nib of different size, just can carry out the production of different size like this on a loom, and the bar of having avoided producing different size needs the trouble that more mold exchange brought.That the present invention has is simple in structure, implement characteristics easily.
