Abstract
The utility model relates to a kind of upper roller of press brake and pressure thick stick draw bail, it is characterized in that: the insertion end of top roll is step-like, first step is screw thread step step, second step is pillow block rank, the end that is inserted into of pressure thick stick is interior step-like, first step is internal thread step, second step is axis hole step, wherein the screw thread step of screw thread step step and the internal thread of internal thread step match, fairlead is laid in axis hole step, pillow block rank are placed in fairlead, the beneficial effect that the utility model can reach is: top roll and pressure thick stick full thread draw bail, be improved to screw thread and pillow block rank connect respectively, total length is constant, but thread size shortens, it effectively overcomes full thread and installs difficulty, be not easy to the shortcoming of demolition and maintenance, its structure is simple, low cost of manufacture, crudy is high, make making and installation simple and convenient, also be convenient to dismounting and safeguard.
Description
technical field:
The utility model relates to a kind of metal forming machinery technical field, specifically a kind of upper roller of press brake and pressure thick stick draw bail field.
background technology:
Veneer reeling machine in the course of the work, its top roll wants close-coupled with pressure thick stick, general employing be full thread connect, such draw bail is compact, and reliability is high, but along with veneer reeling machine is to maximization, large-scale development, the upper roller diameter of veneer reeling machine and length are all in continuous increase, and cause corresponding pressure thick stick to connect the diameter of thread and length also corresponding increase, pressure thick stick is internal thread, difficulty of processing is large, and poor quality ensures; In assembling process, screw thread is without targeting part in addition, and top roll is not easily concentric with pressure thick stick, and installation difficulty is large, and labor intensity of operating staff is high, is difficult to detachable maintaining, causes the reduction of operating efficiency, when going wrong, pressure thick stick screw thread place can only be destroyed, cause pressure thick stick to scrap.
summary of the invention:
Technical problem to be solved in the utility model is: the development of maximizing along with veneer reeling machine, and the full thread between top roll and pressure thick stick connects bad operation, causes operating efficiency to reduce and product rejection.
The utility model provides a kind of upper roller of press brake and pressure thick stick draw bail, and the main step that adopts connects, and shortens reach, is also provided with fairlead in addition, avoids the top roll in installation process and pressure thick stick decentraction.
The purpose of this utility model is achieved in that the insertion end of top roll is step-like, first step is screw thread step step, second step is pillow block rank, the end that is inserted into of pressure thick stick is interior step-like, first step is internal thread step, and second step is axis hole step, and wherein the screw thread step of screw thread step step and the internal thread of internal thread step match, lay fairlead in axis hole step, pillow block rank are placed in fairlead.
The beneficial effect that the utility model can reach is: top roll and pressure thick stick full thread draw bail, be improved to screw thread and pillow block rank connect respectively, total length is constant, but thread size shortens, and it effectively overcomes full thread and installs difficulty, be not easy to the shortcoming of demolition and maintenance, its structure is simple, low cost of manufacture, and crudy is high, make making and installation simple and convenient, be also convenient to dismounting and safeguard.

Detailed description of the invention
Description of symbols in figure: top roll 1(external screw thread step 1.1, pillow block rank 1.2), pressure thick stick 2(internal thread step 2.1, axis hole step 2.2), fairlead 3.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is tradition pressure thick stick and the connecting mode of top roll, and because veneer reeling machine specification is little, this connecting mode is lighter, and processing is also convenient, but along with the increase of veneer reeling machine scale, the drawback of this connecting mode just reveals, such as decentraction, thread damage etc.
A kind of upper roller of press brake that Fig. 2 provides for the utility model and pressure thick stick draw bail, be divided into top roll 1, pressure thick stick 2 and fairlead 3 three part, the insertion end of top roll 1 is step-like, first step is external screw thread step 1.1, second step is pillow block rank 1.2, the end that is inserted into of pressure thick stick is interior step-like, first step is internal thread step 2.1, second step is axis hole step 2.2, wherein the external screw thread of external screw thread step 1.1 and the internal thread of internal thread step 2.1 match, lay fairlead 3 in axis hole step 2.2, pillow block rank 1.2 are placed in fairlead 3.
Top roll 1 is as shown in Figure 3: end is external screw thread step 1.1, pillow block rank 1.2.
Press thick stick 2 as shown in Figure 4: end is internal thread step 2.1, axis hole step 2.2.
Fig. 5, Fig. 6 are the structure of fairlead 3, are annular.
Top roll 1 external screw thread step 1.1 is identical with pressure thick stick 2 internal thread step 2.1 nominal dimension, for threaded engagement connects; Fairlead 3 is arranged in pressure thick stick 2 axis hole step 2.2; Top roll 1 pillow block rank 1.2 and fairlead 3 inner hole connect, and play the guiding role during threaded engagement, play a supportive role when pressing thick stick 2 stressed; Top roll 1 external screw thread step 1.1 is short compared with existing structure by 2/3rds with pressure thick stick 2 internal thread step 2.1 length, and convenient processing and manufacture, Mass accuracy is easy to ensure.
The utility model top roll and pressure thick stick full thread draw bail, be improved to screw thread and pillow block rank connect respectively, and total length is constant, thread size shortens, and it effectively overcomes full thread and installs difficulty, is not easy to the shortcoming of demolition and maintenance, make making and installation simple and convenient, be also convenient to dismounting and safeguard.
