Description

Novel glass pipe autoamtic cutter
Technical field
The present invention relates to glass tube technical field of processing equipment, in particular disclose a kind of novel glass pipe automation cutting dress It sets.
Background technique
Glass is important articles indispensable in home life.In general, the glass of single layer is used a root long glass After glass pipe is cut off and burns bottom, that is, it can be made into.Processing a step important in such glass is carried out to glass tube Cutting, in the past, the pick-and-place for glass tube is all by being accomplished manually, and is that single glass tube is processed into two glasses One glass tube of operation format namely artificial loading, removes the mode of two glasses, when for batch production, feeding and takes For material or very slow, efficiency is not high enough.
In view of the above-mentioned problems, my company provides a kind of cutting feeding station of glass production line, including feeding The side of frame body, the feeding frame body is provided with so that the rotating mechanism of glass tube rotation is (referring specifically to Patent No. CN201820368457.1), the other side is provided with the cutting mechanism that glass tube is cut into length to be processed, the rotating machine First driving machine of structure, the fixed part for being arranged in parallel and rotating in same direction including at least two and the driving fixed part rotation Structure, the cuvette holder are set between the fixed part;Cutting mechanism is cut described in cutting member, drive including glass-cutting pipe The control of the second driving mechanism that cutter member is axially moved back and forth along glass tube and controllable cutting member along the radial motion of glass tube Portion processed;The cutting member is provided with cutting head, and when radial motion of the cutting member to glass tube, the cutting head can touch institute State glass tube;Further include positioning region, be set between rotating mechanism and cutting mechanism, including by a positioning plate, glass to be cut One end of glass pipe peaks on the positioning plate.
The movement of the device cutting member to glass tube be by pulling operating stick downwards manually so that control fixed part with Cutting member movement, glass-cutting pipe.Actually there is no realize to be fully automated for such operation position.In addition cutting mechanism Whether vertical lifting so that cutting member can only axially move back and forth the glass tube of cutting different length, to different-diameter The king-sized glass tube of glass tube especially internal diameter cannot adjust well the height of cutting member to be adapted to.
Thus the present invention devises a kind of novel glass tube autoamtic cutter, in this cutting equipment, cutting Component is moved forward and backward by the sliding rail sliding on platform, and cutting operation frequent in this way is certainly to the abrasion ratio of sliding rail It is larger, it requires that sliding rail wearability is high.
Present some materials for being commonly used to make sliding rail are mostly cast iron materials, and cast iron materials hardness is big, such as Patent No. A kind of wear-resistant cast iron material is provided in 201310085150.2 patent of invention, it is by steel scrap, chromium steel, manganese iron, ferrosilicon, molybdenum Iron, vanadium iron, ferronickel, ferro-boron, ferrotianium and the various components of rhenium iron are made after being smelted, cast and being heat-treated by a certain percentage, should Cast iron materials wear-resisting property is high, but needs the precious metals such as molybdenum, nickel, rhenium, at high cost.So how to provide a kind of at low cost Good sliding rail material is the task of top priority to honest and clean, wearability again.Application No. is propose Metal Substrate in 02106782.1 patent of invention Wear-resisting reinforced phase is added in body to improve the thinking of material wear ability, application No. is mention in 200910144386.2 patent of invention Go out with nano-ceramic powder disperse and strengthened casting alloy, has improved the thinking of material wear ability.On the other hand, it sends out in the prior art The carbon-boron compound of existing high rigidity can effectively improve the wearability of ferrous alloy, and if into one in this kind of ferro-boron base alloy material Ceramic enhancement phase is added in step, will further improve the wearability of material.
Summary of the invention
The present invention lacks glass tube autoamtic cutter for the prior art, and what device sliding rail wearability needed to improve lacks Point provides a kind of novel glass pipe autoamtic cutter.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:
A kind of novel glass pipe autoamtic cutter, including rack, the side of rack is provided with so that glass tube rotates Rotating mechanism, the other side is provided with the cutting mechanism that glass tube is cut into length to be processed, it is characterised in that: cutting mechanism Including the platen being arranged on the rack, platen length direction is parallel to rack length direction, slides the bracket being fixed on platen, The strut being movably fixed on bracket, the cutting member positioned at strut front end, strut can be pressed downward by, which being fixed on bracket, to cut Part contacts the first driving mechanism cut with glass tube, and is fixed on bracket and entire bracket can be driven along rack length The second driving mechanism that direction moves forward or back, is further fixed on limiting block on the position among strut front cutting part and bracket Block, the rear end of strut are further fixed on countersunk head, and countersunk head balances each other with limited block, guarantee not to be pressed downward propping up in the first driving mechanism When bar, strut be it is horizontal positioned, the cutting member of strut front end does not contact glass tube;
