Description
Technical field
The present invention relates to a kind of occasion clamping device that is applied to steel tube gang saw machine and the compound clamping of other sawing needs, particularly the compound clamping device of a kind of comb.
Background technology
What traditional clamping device horizontal-clamping adopted is hydraulic synchronization, easily causes comb center and saw blade misalignment after the clamping.Vertical clamping adopts two oil cylinders, also is to adopt hydraulic synchronization, easily causes vertical clamping jam phenomenon.Simultaneously also do not possess the clamping cutter relieving function, easily scratch section when saw blade lifts, and do not have the saw blade retainer, the sawing cross section quality is unstable.Vertical clamping, horizontal-clamping are not mounted in the casing, and huge structure is difficult for installing, and the stub bar of clamping is longer, and lumber recovery is low etc.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the object of the present invention is to provide the compound clamping device of a kind of comb, the steel pipe that reliably clamping is in a row, but the minimum tube head of clamping is 50mm, by adjustable saw blade retainer, keep the stability of saw blade Lower Half simultaneously, thereby improved the lumber recovery of steel pipe, improved the surface quality of Tube Cutting section, and the noise that produces when having reduced sawing; In addition, this device can make the sawing section separate with saw blade after sawing is finished, and saw blade can not scratch section in lifting process, and automatically resets before next time sawing, has satisfied the full-automatic technological requirement of steel tube gang saw machine; That this device has is simple and compact for structure, good clamping effect and can realize the advantages such as automation control.
In order to achieve the above object, technical scheme of the present invention is achieved in that
The compound clamping device of a kind of comb, comprise fixed clamping device 14 and floating clamping device 13 with same structure, a side that is connected with main frame is fixed clamping device 14, the outside be called floating clamping device 13, floating clamping device 13 and fixed clamping device 14 link together by the piston rod of tool retracting device 12, described fixed clamping device 14 comprises the horizontal-clamping oil cylinder 1 that is fixed on the casing both sides, two horizontal-clamping oil cylinders 1 are respectively by first connecting rod 2, second connecting rod 10 and each self-corresponding first synchronous tooth bar 5, the second synchronous tooth bar 7 connects, and first connecting rod 2 and second connecting rod 10 are respectively in upper and lower sides and synchromesh gear 6 engagements; Be to slide up and down the vertical clamping device 3 that is connected with vertically-guided post 4 directly over the casing, vertically-guided post 4 is fixed on the casing, solid vertical clamping oil cylinder 8 under the casing, and vertical clamping oil cylinder 8 all is connected on the vertical link 9 with vertical clamping device 3; Saw blade retainer 11 and tool retracting device 12 are installed on the vertical clamping device 3.
Advantage of the present invention is:
1. adopt 4 clampings, in the time of can guaranteeing clamping large diameter thin wall pipe, steel pipe can be out of shape.
2. horizontal-clamping adopts hydraulic clamp, and mechanical synchronization has been saved complicated hydraulic synchronization loop.
3. vertical clamping adopts single oil cylinder, makes when clamping and can not produce the jam phenomenon, and having stable behavior is reliable.
4. has the clamping cutter relieving function, protection sawing cross section quality.
5. the saw blade retainer is all installed in the saw blade both sides, and is stable when making saw blade sawing, improves the sawing cross section quality.
6. horizontal-clamping and vertical clamping are in same plane, and the minimum tube head of clamping is 50mm, improves lumber recovery.
7. compact overall structure is convenient to install.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the AA of Fig. 1 is to cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are done and to be described in detail.
With reference to Fig. 1, Fig. 2, the compound clamping device of a kind of comb, comprise fixed clamping device 14 and floating clamping device 13 with same structure, a side that is connected with main frame is fixed clamping device 14, the outside be called floating clamping device 13, floating clamping device 13 and fixed clamping device 14 link together by the piston rod of tool retracting device 12, described fixed clamping device 14 comprises the horizontal-clamping oil cylinder 1 that is fixed on the casing both sides, two first connecting rods 2 that horizontal-clamping oil cylinder 1 passes through respectively, second connecting rod 10 and each self-corresponding first synchronous tooth bar 5, the second synchronous tooth bar 7 connects, first connecting rod 2 and second connecting rod 10 are respectively in upper and lower sides and synchromesh gear 6 engagements, when 1 work of two horizontal-clamping oil cylinders, realize the synchronous of two side cylinders by synchromesh gear 6; To slide up and down the vertical clamping device 3 that is connected with vertically-guided post 4 directly over the casing, vertically-guided post 4 is fixed on the casing, solid vertical clamping oil cylinder 8 under the casing, vertical clamping oil cylinder 8 all is connected on the vertical link 9 with vertical clamping device 3, slides up and down thereby make vertical clamping oil cylinder 8 drive 3 vertical clamping devices; Saw blade retainer 11 and tool retracting device 12 are installed on the vertical clamping device 3, tool retracting device 12 is a nonstandard oil cylinder, cylinder body is fixed on the fixed clamping device 3, tool retracting device 12 piston rods are fixed on the floating clamping device, thereby fixed clamping device 14 and floating clamping device 13 are linked together.
The specific works principle of this device is as follows: whole clamping device is installed on the lathe bed of saw in the integral hoisting of A face.When the saw blade sky proceeds on the steel pipe along 15mm, this moment, tool retracting device 12 was in the state of stretching out, and vertical clamping device 3 low pressure in fixing to clamp are depressed, and the control of passing ratio valve forms secondary pressure, then the horizontal-clamping oil cylinder 1 of the right and left clamps, and drives the first synchronous tooth bar 5 by first connecting rod 2; Another horizontal-clamping oil cylinder clamps simultaneously, drives 7, two tooth bars of the second synchronous tooth bar by second connecting rod 10 and realizes synchronous clamping by synchromesh gear 6, guarantees comb center and saw blade center superposition.Floating clamping mechanism also carries out identical action simultaneously.Last tool retracting device 12 is retracted, and floating clamping device 13 and fixed clamping device 14 closely are close together, and the vertical clamping device 3 that then fixes to clamp in 14 switches to high pressure.This moment, whole clamping device formed an integral body, and pipe clamping in a row is firm, and the saw blade worker advances to cut off pipe.After sawing finished, tool retracting device 12 stretched out, and by floating clamping device 13 pipe that cuts off was hauled out certain distance, and section and saw blade are separated, and then saw blade also stretches out a segment distance by other mechanism, and saw blade and rear section are separated, and then saw blade lifts.Horizontal-clamping is opened, and vertical clamping device 3 is opened, the discharging of pipe leading portion, and back segment continues material loading.Prepare next time sawing.Whole sawing process adopts Automatic Control, repeats sawing.
