[specific embodiment]
Consult Fig. 3,4,5, one preferred embodiment of cutoff device of the present invention is to cut a not shown wire rod with moving back and forth, comprise: what a basal wall unit 1, a cutting knife tube 2, a resetting means 3, were erected at cutting knife tube 2 front ends cuts unit 4, and one is used for driving this cutting knife tube 2 and cuts the drive plate 5 that direction 20 moves back and forth along one.
This basal wall unit 1 comprises: a basal wall 11, a cutting knife cylinder base 12, four can be adjusted the briquetting assembly 13 that this cutting knife cylinder base 12 reaches position, the left and right sides up and down, and a skew side plate 14 that is installed in cutting knife cylinder base 12 rears adjustably.Wherein basal wall 11 has basal plane before one 111, with at interval back basal plane 112 of preceding basal plane 111 front and back, always put on assembly hole 113, the one vertical assembly hole 113 of stating basal plane 111,112 and the lines passage 114 of bootable wire rod travel path, and one from after basal plane 112 be arranged with and be parallel to the supporting surface 115 of this back basal plane 112 forward.
And this cutting knife cylinder base 12 is can adjust in the assembly hole 113 that is installed in to the position basal wall 11 up and down, comprise: a barrel 121 around a central axis, one by this barrel 121 define the tube hole that forms 122, one from barrel 121 radially outstanding one first pushed away projection 123, and one is pushed away projection 124 at second of barrel 121 rears.Wherein barrel 121 has minor diameter part 125, a large-diameter portion 126, in the wings forwardly and is engaged between the two shoulder 127, and several tanks 128 that are arranged with from shoulder 127, each tank 128 all has one and is parallel to first of supporting surface 115 and supports portion 129.This briquetting assembly 13 of the present invention is to be erected at the outer peripheral edges that first of cutting knife cylinder base 12 is pushed away projection 123 jointly, and what be used for fixing or adjust this cutting knife cylinder base 12 reaches position, the left and right sides up and down.14 of this skew side plates are the rears that is installed in cutting knife cylinder base 12 disassembledly, because focusing on of the present invention's improvement: how cutting knife tube 2 resets, how to drive 12 adjustment of cutting knife cylinder base as for briquetting assembly 3 and reach position, the left and right sides up and down, and how skew side plate 14 drives structures such as cutting knife tube 2 adjustment front and back positions, be not feature of the present invention, no longer explanation.
Consult Fig. 3,6,7, this cutting knife tube 2 can cut direction 20 along this and reciprocatingly be erected on the tube hole 122 of cutting knife cylinder base 12, comprise: minor diameter part 125 interior cutting knife assembled portion 21, that are through cutting knife cylinder base 12 radially enlarge also installation portion 22, a roller bearing 23 of the large-diameter portion 126 of corresponding cutting knife cylinder base 12, and two saddles 24 that roller bearing 23 are erected at installation portion 22 rears with rotary way.Wherein cutting knife assembled portion 21 has a front end 211, and the diameter of installation portion 22 is greater than cutting knife assembled portion 21, have one and shoulder 127 front and back of cutting knife cylinder base 12 opposite face 221 at interval on it, on opposite face 221, offer the docking groove 222 of several and tank 128 straight line correspondences, each docking groove 222 all have one and first support portion 129 front and back corresponding at interval second support portion 223.
This resetting means 3 is to make cutting knife tube 2 tool elastic load ground perseverances pushing tow backward, comprise: several elastic components 31 that quantity and tank 128 are identical, it is to be installed in respectively in this tank 128 and the axial corresponding docking groove 222, and contact is supported 129,223 in portion at first and second.
This cuts the action that unit 4 is used for carrying out the severing wire rod, comprise: one is fixed on the Cutter apron 41 of the front end 211 of cutting knife tube 2, and one and Cutter apron 41 fixing and have one and hold the cutting knife 42 in line hole 421, this holds line hole 421 can moving because of Cutter apron 41, and and cable channel 114 is corresponding or dislocation, because this design that cuts unit 4 is not feature of the present invention, below no longer explanation.
This drive plate 5 is to be subjected to not shown power set to drive, and can reciprocally move along workmanship's direction 50, above-mentioned workmanship's direction 50 is perpendicular to cutting direction 20, and this drive plate 5 comprises: one toward the outstanding tabular cam 51 of cutting knife tube 2 directions, this tabular cam 51 has one and the drive surface 511 that reclines of the roller bearing 23 of cutting knife tube 2, this drive surface 511 has a starting point 512, and one and the propelling movement point 513 of starting point 512 with difference in height.How aforementioned drive plate 5 moves back and forth that to improve emphasis also irrelevant with the present invention, no longer explanation.
Cutoff device of the present invention position non-when cutting the position shown in Fig. 3,4, be subjected to the pushing tow of resetting means 3, these cutting knife tube 2 perseverances move (being exactly the figure right side) backward, and and the drive surface 511 of drive plate 5 recline, that is to say, the roller bearing 23 of this cutting knife tube 2 is resisted against on the starting point 512 of drive plate 5 accordingly, at this moment, and the appearance line hole 421 of this cutting knife 42 and cable channel 114 correspondences on the basal wall 11.
Consult Fig. 3,8, when cutoff device of the present invention will cut the position when being transformed into one of Fig. 8 and cutting the position by Fig. 3 non-, the propelling movement point 513 of this drive plate 5 little by little moves toward the direction of roller bearing 23, because this starting point 512 and 513 of propelling movement points have one section difference in height, therefore, when pushing the corresponding roller bearing 23 of point 513, whole cutting knife tube 2 can overcome the elastic force of resetting means 3 to be given prominence to forward, and the appearance line hole 421 and the cable channel on the basal wall 11 114 that therefore drive on the cutting knife 42 misplace, and with the wire rod severing, simultaneously resetting means 3 also can be compressed and accumulates reseting elasticity.Identical reason, when drive plate 5 is activated, and when starting point 512 was moved toward roller bearing 23 directions gradually, this cutting knife tube 2 will be subjected to resetting means 3 and disengage shoring of elastic force, and by the non-position that cuts that the position is transformed into Fig. 3 that cuts of Fig. 8.
In design, the present invention also can be designed to tank 128 and docking groove 222 around the ring concavity in tube hole 122, as long as and that this resetting means 3 has an elastic component 31 that is set in this tank 128 and the docking groove 222 is just passable, perhaps directly supporting portion 129 with first is located on the supporting surface 115 of basal wall 11, and this second supports portion 223 and is directly arranged on the installation portion 22 of cutting knife tube 2, borrow elastic component 31 directly to pull on the opposite face 222 of basal wall 11 and cutting knife tube 2 on the top, can reach the purpose of hiding resetting means 3 equally.That is to say that the present invention is in design having docking groove 222, tank 128, and number elastic component 31 be necessary, is not necessity to have this cutting knife cylinder base 12, briquetting assembly 13 and to be offset side plate 14 also in the design.
By above explanation as can be known, the present invention is located at resetting means 3 first and second design to 129,223 in portion of basal wall unit 11 and cutting knife tube 2 hidingly, not only do not see the cutoff device of part forming machine in the past, this design has more dwindles overall volume, and saves advantage such as placing space.
