Abstract

The invention discloses a floating type cutting device, which comprises a rack. A support plate is connected to the rack. A lower cutter mounting plate is fixedly arranged on a cushion block. A lower cutter is fixedly arranged on the lower cutter mounting plate. Cutter frame body upright posts are connected to the lower cutter mounting plate. A cutter frame body cover plate is connected to the cutter frame body upright posts. A cutting cylinder is fixedly arranged on the cutter frame body cover plate. An upper cutter is arranged on an upper cutter mounting plate. The cutting cylinder is connected with the upper cutter mounting plate through a floating joint. The two ends of the upper cutter are in a guide foot form, and the middle part of the upper cutter is a cutting edge part. The lateral surfaces of guide feet at the two ends of the upper cutter contact with guide devices to guide upward-downward movement, so that the cutting edge part of the upper cutter is positioned outside a cutting edge of the lower cutter. The upper cutter is inclined by 3 to 4 degrees relative to the lower cutter. The floating type cutting device is rational in structure; the cutting accuracy of a polyvinyl chloride/polyethylene glycol terephthalate (PVC/PET) heat-shrinkable T bush and the like is improved; and the shortcomings of burrs, beveling and the like of cut edges are overcome.

Description

Floating type cutting means

Technical field

The present invention relates to automatic cutting apparatus field, especially the device that cuts of the fixed length of heat-shrinkable T bush such as aluminium electrolutic capacitor PVC/PET.

Background technology

High speed development along with converter technique; The automated production of big-and-middle-sized aluminium electrolutic capacitor has also obtained corresponding progress; Fixed length at big-and-middle-sized aluminum electrolytic capacitor casing cuts in the fully-automatic equipment; To the quite high required precision that cuts of capacitor casing, every cuts the casing length of getting off and will equate, and cutting edge can not be jagged, defective such as hypotenuse.Sleeve pipe cut outward appearance and the serviceability that quality directly influences product.

Existing cutting method mainly contains manually and cuts, rigidity (fixing) gap cutting means, regulate the cutting means in cutter gap up and down etc. based on wedge mechanism.The disclosed cutting means of patent CN 201783697 U, on it cutting knife be installed in the joining installing plate of line slideway slide block on to realize moving up and down guiding.The disclosed tab cutting device of another patent CN 101774041 B, cutting knife is installed on the upper cutter frame that links through linear bearing and two guide rods to realize moving up and down guiding on it.But these two kinds of cutting means gap of cutter up and down must guarantee through accurate assembling; Assemble the improper edge of a knife excesssive gap or too small up and down that is prone to cause; When process of cutting and replacing cutting knife, adjustment difficulty in the gap of the edge of a knife is consuming time many up and down; Also be prone to cause cutter edge of a knife rigidity contact up and down, produce the tool setting phenomenon.The disclosed plate shearing machine of patent CN 201833057 U is gap blade uniformity adjusting device up and down; Gap blade adjustment is up and down realized in position through adjusting a plurality of tapered wedges change bottom knife; On this method rigidity gap, high to adjustment personnel specification requirement is installed, along with the wearing and tearing that cut the process blade, replacing etc.; Need real-time adjusting play, adjust the improper cutter tool setting phenomenon up and down that also is prone to cause.Disclosed shear gap adjustment of patent CN 101905353 B and blade pressing and locking device; Gap blade adjustment is up and down realized in position through changing adjustment pad change bottom knife; Adjust for the rigidity gap that level is arranged between the bottom knife on this method, adjust the improper cutter tool setting phenomenon up and down that is prone to cause.It is thus clear that existing cutting method requires height with device to assembly precision, be rigidity (fixing) gap between the cutter up and down, be not easy to adjustment, there are hidden danger such as cutter tool setting up and down, the improper defectives such as object is jagged, hypotenuse that are prone to cause cut are adjusted in the cutter gap up and down.

Summary of the invention

The object of the present invention is to provide a kind of rational in infrastructurely, improve the precision that cuts of heat-shrinkable T bush such as PVC/PET, avoid the floating type cutting means of defectives such as cutting edge burr, hypotenuse.

Technical solution of the present invention is:

A kind of floating type cutting means is characterized in that: comprise frame, gripper shoe is connected on the frame; Following cutting knife installing plate is fixed on the cushion block; Following cutting knife is fixed on down on the cutting knife installing plate, and the tool-post structure column is connected in down on the cutting knife installing plate, and the tool-post structure cover plate is connected on the tool-post structure column; Cut cylinder and be fixed on the tool-post structure cover plate, last cutting knife is installed on the cutting knife installing plate, cuts cylinder and connects through floating junction with last cutting knife installing plate; Last cutting knife two ends are guiding pin form, middle cutting edge part for cutting; The guiding pin side maintenance at last cutting knife two ends contacts with guider and realizes moving up and down guiding, makes the outside of the cutting edge part of cutting knife at following cutting knife cutting edge; Last cutting knife tilts 3 ° ~ 4 ° to following cutting knife.

Said guider has two, cooperates with last cutting knife two ends respectively, is symmetrical set with respect to cutting cylinder; Each guider includes three bulb plungers, two guide pin bushings going up cutting knife pressing plate, two guide pillars and be arranged above and below; Guide pin bushing is enclosed within on the guide pillar; Guide pillar is connected on the cutting knife adjustment installing plate that floats with soket head cap screw, and the cutting knife adjustment installing plate that floats is connected on the gripper shoe; The bulb plunger surface has external screw thread, and the bulb plunger is screwed on the cutting knife adjustment installing plate that floats; The steel ball of bulb plunger front end is pressed on the cutting knife pressing plate through spring, and last cutting knife pressing plate is pushed down the front end face of cutting knife; On cut two ends guiding pin side keep contacting the realization guiding that moves up and down with two guide pin bushings.

The present invention is rational in infrastructure, and last cutting knife two ends are designed with the guiding pin, and two survey the guiding pin remains at down outside the cutting edge of cutting knife, is assembling when adjusting with tool changing like this, and tool setting and hidden danger such as stuck can not take place; Cylinder drive to be gone up cutting knife up and down during rectilinear motion through floating junction, and the guiding pin side of last cutting knife both sides keeps respectively contact realization to the guiding that last cutting knife moves up and down with 2 guide pin bushings, and it is steady to move up and down; With respect to cutting the guider that cylinder is symmetrical set; Go up cutting knife on the cutting knife pressing plate elastic compression through the contact of 3 bulb plungers of every side front end steel ball point; Make the cutting edge of going up cutting knife and following cutting knife keep elastic compression, the size that can conveniently change thrust through adjusting bulb plunger realizes the elastic gap adjustment; The said said relatively cutting knife down of cutting knife of going up tilts 3 ° ~ 4 °, makes to put gradually when cutting and cuts.The present invention is carrying out tool changing and when adjustment assembling, and tool setting and phenomenon such as stuck can not take place, and the quality that cuts of heat-shrinkable T bush such as aluminium electrolutic capacitor PVC/PET can be effectively improved in the adjustment gap between the cutter up and down easily, effectively avoids defectives such as burr, hypotenuse.
