Abstract

The invention relates to a winding shaft bracket in a slitting machine. The invention adopts a cylinder, a connecting rod and a pair of guide rails to realize the translation and support of the rewinding shaft bracket, and connects the two brackets into one body, and fixes the rewinding shaft with the bracket cylinder and clamping plate. In the past, it not only relied on the large arc of the cylinder to move the rewinding shaft bracket but also relied on the cylinder to support the bracket, and the product quality was affected by the vibration of the bracket caused by the instability of the gas in the cylinder, that is, the pulsation of the gas source, and the two brackets Defects that damage product quality due to errors caused by inconsistencies in movement and support. The structure of the invention is simple, stable and reliable, and the product quality is guaranteed, and the processing difficulty of the bracket is greatly reduced, the cost is also greatly reduced, the strength of the upper and lower rolls is reduced, it is not easy to be damaged, and the maintenance cost is saved.

Description

The cutting machine of improved coiling shaft bearer

Technical field

The present invention relates to a kind of machinery, particularly a kind of cutting machine of coiling shaft bearer.

Background technology

Before the present invention, the coiling shaft bearer on the existing cutting machine is to adopt the cylinder that is installed on the drawbar frame to connect connecting rod, and connecting rod is connected with a coiling shaft bearer, connects another coiling shaft bearer by another connecting rod again.After the rolling material has been loaded onto coiling shaft bearer, in order to hold coiling shaft bearer, need cylinder coiling shaft bearer with the air pressure holder always, and gas is extremely unsettled, i.e. the pulsating nature of source of the gas is in Scroll high-speed cruising process, will produce the shake of coiling shaft bearer, make Scroll running state instability, influence the rolling quality, cause product loss.Simultaneously, because cylinder directly is connected with a coiling shaft bearer, be connected with another coiling shaft bearer by connecting rod, make two coiling shaft bearer can't accomplish synchronized operation, will produce error, and the direct result that this nonsynchronous error is brought is exactly product design decline, even the defect ware increase, causes economic loss.In addition, the processing of coiling shaft bearer is the work of a difficulty always, where processes slightly to make mistakes, and will influence whole coiling shaft bearer quality, even can only scrap.In addition, the loading of Scroll, unload also very painstakingly down, labour intensity is big.Above-mentioned these problems are insurmountable in the material cutting machine for many years always, to the influence of entire product quality much larger than other factors.

Summary of the invention

Purpose of the present invention just is to overcome above-mentioned defective fully, designs, develops a kind of non-jitter, zero-error and simple and practical coiling shaft bearer.

Technical scheme of the present invention is: the cutting machine of improved coiling shaft bearer, cylinder is installed on the drawbar frame, cylinder one end connects connecting rod, its major technique is characterised in that connecting rod connects coiling shaft bearer, two coiling shaft bearer link into an integrated entity, coiling shaft bearer and guideway sliding block joint, guideway is installed on the drawbar frame.

Advantage of the present invention and effect are to utilize cylinder, connecting rod and guide rail, and the large-scale running orbit of circular arc of volume, last volume on the past coiling shaft bearer is changed into parallel moving, and make the coiling shaft bearer volume dwindle greatly; Behind last volume, utilize the drawbar frame itself to bear the weight of Scroll, avoided always with the cylinder rolling product design that the coiling shaft bearer shake that brings because of unstable gas of supporting that coiling shaft bearer causes brought disaster to of ventilating; Make an integral body owing to two coiling shaft bearer are united two into one, avoided the influence that error caused of two coiling shaft bearer the rolling product design; Two coiling shaft bearer are made one and parallel moving, make that the relative prior art of structure of coiling shaft bearer is simple, difficulty of processing reduces greatly, and cost also descends a lot; Last roll up, unload when volume also be very easy to, simple, labour intensity reduces, and the damage that is difficult for, and has saved maintenance time and expense.

The specific embodiment

As shown in Figure 1, 2, 3, cylinder 1 is installed on the drawbar frame 6, and an end of cylinder 1 connects an end of connecting rod 2, connecting rod 2 comprises several link members, synthetic connecting rod 2, and its other end connects coiling shaft bearer 4, coiling shaft bearer 4 has comprised that two carriages unite two into one, and link into an integrated entity; The parallel of coiling shaft bearer 4 moved in the scope of guideway 7, and promptly it can only translation on guide rail 7 pairs, and guideway 7 is fixedly connected on the drawbar frame 6; At two Scrolls 9 of coiling shaft bearer 4 two ends carrying, clamp 3 is set herein, clamp 3 one sides are provided with clamp cylinder 5 and are attached thereto.

During work, originally coiling shaft bearer 4 does not contact with Scroll 9, and then connecting rod 2, coiling shaft bearer 4 are all on the long and two-short dash line position in Fig. 1; When needs carry Scroll 9 (upper and lower each), cylinder 1 makes connecting rod 2 left, promoting coiling shaft bearer 4 moves with a left side is parallel along guide rail 7, its upper/lower terminal carries Scroll 9 (solid line position among Fig. 1) respectively, promote the long and two-short dash line position (Fig. 3) of clamp 3 by the carriage cylinder on the coiling shaft bearer 45 from long and two-short dash line position to the right on the left side, clamp 3 just in time blocks the spindle nose of Scroll 9, and Scroll 9 is completely fixed.During unloading, at first clamp cylinder 5 is return, this moment, clamp 3 was in free state, and Scroll 9 no longer is stuck, and promoted cylinder 1 again, make the long and two-short dash line position in connecting rod 2, the coiling shaft bearer 4 to Fig. 1, then coiling shaft bearer 4 breaks away from Scroll 9, at this moment, and along with moving of coiling shaft bearer 4, clamp 3 is opened, and can take off the material of rolling.During carrying, repeat above-mentioned steps again.

Principle of the present invention is not limited to the present invention.

Claims
