Abstract
The utility model relates to a structure for solving the problem of the blockage of a push broach of a circular cutter, which comprises a cutter changing tower shaft, a circular cutter sleeved on the cutter changing tower and a circular cutter shaft, wherein a transition taper sleeve with a large end sleeved at the end part of the circular cutter shaft is arranged between the cutter changing tower shaft and the circular cutter shaft, the outer diameter of the large end of the transition taper sleeve is equal to that of the circular cutter shaft, and the outer diameter of the small end of the transition taper sleeve is equal to that of the cutter changing tower shaft. When the structure can realize tool changing, the disc cutter is stably pushed between the tool changing tower shafts and the disc shear shafts with different diameters, and the problem of blocking of the disc cutter cannot occur.
Description
Technical Field
The utility model relates to a structure for solving the problem of blockage of a push broach of a circular cutter.
Background
In the processing of the non-ferrous metal plate strip, according to the requirements of customers, a wide strip needs to be longitudinally cut, and a wide strip is cut into a plurality of narrow strip coils. The purpose of the disc shear is to use a device of the disc shear, which utilizes an upper group of circular disc cutters and a lower group of circular disc cutters to cut and strip the strip material, thereby realizing the purpose that the wide strip material is changed into the narrow strip material.
The disc cutter needs to be replaced frequently because the width of the cut strip required by different customers is different. In order to increase the tool changing efficiency, a tool changing tower is usually arranged beside the machine train, the disc cutters needing to be changed are arranged on a shaft of the tool changing tower in advance, and then the whole set of disc cutters are pushed onto a shaft of the disc shear.
It is sometimes the case that the tool turret shaft diameter is smaller than the diameter of the disc shear shaft due to wear or manufacturing reasons (see fig. 1), with a step at the point where the two shafts meet. Therefore, when the disc cutter is pushed to the disc shear shaft from the tool changing tower shaft during tool changing, the disc cutter can generate blocking at the step position, the situation that the push cutter is not smooth can occur, even the situation that the push cutter is manually lifted to the disc shear shaft is needed, and the tool changing efficiency is seriously influenced.
In general, to solve the above problem, it is necessary to rework the tool turret shaft to ensure that the shaft diameter is consistent with the diameter of the disc shear shaft, but it takes a high manufacturing cost and a long waiting time.
Disclosure of Invention
The utility model aims to provide a structure for solving the problem of blocking of a push broach of a circular cutter.
The technical scheme of the utility model is as follows: the utility model provides a solve structure that circle disc cutter push-type broach card hinders, includes that tool changing tower axle and cover put the circle disc cutter on the tool changing tower to and circle disc scissors axle, the one end that is provided with the major part between tool changing tower axle and the circle disc scissors axle cup joints the transition taper sleeve at circle disc scissors axle tip, the one end external diameter of transition taper sleeve major part equals with the external diameter of circle disc scissors axle, and the one end external diameter of the little head of transition taper sleeve equals with the external diameter of tool changing tower axle.
Furthermore, a shaft neck sleeved with the transition taper sleeve is arranged on the end head of the disc shear shaft, and a shaft head used for extending into a shaft hole of the tool changing tower is arranged on the end head of the shaft neck.
Furthermore, the outer diameter of one end of the big end of the transition taper sleeve is 200mm, and the outer diameter of one end of the small end of the transition taper sleeve is 198 mm.
Compared with the prior art, the utility model has the following advantages: when the structure can realize tool changing, the disc cutter is stably pushed between the tool changing tower shafts and the disc shear shafts with different diameters, the problem of blocking of the disc cutter cannot occur, and the operation and the use are simple and convenient.

Detailed Description
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to FIGS. 1 and 2
The utility model provides a solve structure that circle disc cutter push-out tool card hinders, includes that tool changing tower axle 10 and cover put the circle disc cutter 20 on the tool changing tower to and circle disc shear axis 30, the one end that is provided with the major part between tool changing tower axle and the circle disc shear axis cup joints the transition taper sleeve 40 at circle disc shear axis tip, the one end external diameter of transition taper sleeve major part equals with the external diameter of circle disc shear axis, and the one end external diameter of the little head of transition taper sleeve equals with the external diameter of tool changing tower axle to make circle disc cutter can follow the tool changing tower axle and get into circle disc shear axis through the transition taper sleeve smoothly, avoid producing the card at two joint position 41 and hinder.
In this embodiment, in order to fit the transition taper sleeve, a shaft neck 31 is provided at the end of the circular scissors shaft and is fitted with the transition taper sleeve. The end of the shaft neck is provided with a shaft head 32 which is used for extending into the shaft hole 11 of the tool changing tower shaft so as to ensure the stability when the tool changing tower shaft is connected with the disc shear shaft.
In the embodiment, the outer diameter of one end of the big end of the transition taper sleeve is 200mm and is equal to the outer diameter of the disc shear shaft; the outer diameter of one end of the small end of the transition taper sleeve is 198mm and is equal to the outer diameter of the tool changing tower shaft.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
