The person skilled in the art would like to be able to propose more material lifting slider driving devices with different structures to meet the needs of different customers.
Disclosure of Invention
The utility model provides a material slider drive arrangement that lifts of metal rod material clipper, the utility model discloses the technical problem who solves how to propose another kind of drive arrangement that can drive material lifting slider, and can effectively bear the effort of retreating of material lifting slider.
The to-be-solved technical problem of the utility model can be realized through the following technical scheme: a lifting slide block driving device of a metal bar material cutting machine comprises a headstock and a sliding tool apron connected with the headstock in a sliding manner; the material lifting sliding block is connected with the sliding tool apron in a sliding mode, and the moving direction of the material lifting sliding block relative to the sliding tool apron is parallel to the moving direction of the sliding tool apron relative to the machine head seat; the material lifting slide block driving device comprises a screw and a motor, the motor comprises a shell and a rotating shaft, and the shell is fixed on the sliding tool apron; the axial lead of the screw and the material lifting slide block are arranged in parallel relative to the moving direction of the sliding tool apron;
the first scheme is as follows: one end of the screw rod is in threaded connection with the material lifting sliding block, the middle of the screw rod is in threaded connection with the sliding tool apron, the spiral direction of the middle thread of the screw rod is opposite to that of the end of the screw rod, and the other end of the screw rod is connected with a rotating shaft of the motor.
Scheme II: one end of the screw rod is in threaded connection with the material lifting sliding block, the middle of the screw rod is in axial positioning connection with the sliding tool apron, and the other end of the screw rod is connected with a rotating shaft of the motor.
The third scheme is as follows: one end of the screw rod is connected with the material lifting sliding block in an axial positioning mode, the other end of the screw rod is connected with a rotating shaft of the motor, and the middle of the screw rod is in threaded connection with the sliding tool apron.
Compared with the prior art, the material lifting sliding block of the metal bar material cutting machine is driven by a motor, the motor is an electric motor or a pneumatic motor or a hydraulic motor, and obviously, the rotating shaft of the motor rotates. When the pivot of motor rotated, the pivot drove the screw rod and rotated, first scheme: because the screw rod is in threaded connection with the material lifting sliding block and is also in threaded connection with the sliding tool apron, and the spiral directions are opposite, when the screw rod rotates, the screw rod not only axially moves relative to the sliding tool apron, but also axially moves relative to the material lifting sliding block; the second scheme is as follows: because the screw rod is in threaded connection with the material lifting sliding block and is in axial positioning connection with the sliding tool apron, the screw rod only rotates relative to the sliding tool apron when the screw rod rotates and does not axially move, and the screw rod axially moves relative to the material lifting sliding block. Therefore, under the condition that the motor has the same rotating speed and the screw has the same pitch, the moving stroke of the material lifting slide block in the first scheme is larger than that of the material lifting slide block in the second scheme, in other words, the first scheme is more beneficial to rotating the motor with low speed and high torque.
If the rotating shaft drives the screw rod to rotate in the forward direction, the screw rod enables the space between the material lifting sliding block and the motor to be increased, and the metal bar is clamped by the dynamic shearing die and the material lifting sliding block which are arranged on the sliding tool apron; if the rotating shaft drives the screw rod to rotate reversely, the screw rod enables the space between the material lifting sliding block and the motor to be reduced, and the metal bar material is released.
The middle part of the screw rod is in threaded connection or in axial positioning connection with the sliding tool apron, so that the backward acting force of the material lifting sliding block is borne by the sliding tool apron, and the motor is effectively protected.
Because the threaded connection structure has the self-locking characteristic, the screw rod cannot rotate when the material lifting slide block bears the retreating acting force, so that the stability of clamping the metal bar by the dynamic shearing die and the material lifting slide block is improved, in other words, when the metal bar is sheared, the material lifting slide block cannot retreat, and the end face smoothness of the sheared metal workpiece is improved.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
The first embodiment is as follows: as shown in fig. 1 to 4, the metal bar material cutting machine includes a headstock 1 and a slide tool holder 2 slidably connected to the headstock 1, and the description shows that the slide tool holder 2 moves horizontally relative to the movement direction of the headstock 1.

A support 8 is fixed on the other end face of the sliding tool apron 2, one end of the support 8 penetrates out of the tool apron seat 1, a shell 7a of the motor 7 is fixedly connected with one end of the support 8 through bolts and nuts, so that the shell 7a is fixed on the sliding tool apron 2, and the arrangement structure is convenient for installing and maintaining the motor 7.
The axial lead of the screw 6 and the axial lead of the rotating shaft 7b in the motor 7 are concentric and horizontally arranged, and the axial lead of the screw 6 and the material lifting slide block 9 are arranged in parallel relative to the moving direction of the sliding tool apron 2. One end of the screw 6 has a first thread 6a, and the middle of the screw 6 has a second thread 6b, the first thread 6a having a direction opposite to that of the second thread 6 b.
The material lifting slide block 9 comprises a slide block base 9a and a material lifting chuck 9b fixed on the slide block base 9a through a bolt, a first mounting hole is formed in the slide block base 9a, a first threaded sleeve 9c in threaded connection with one end of the screw rod 6 is arranged in the first mounting hole, and the first threaded sleeve 9c is fixedly connected with the slide block base 9a, so that threaded connection between one end of the screw rod 6 and the material lifting slide block 9 is achieved. The fixing structure between the first threaded sleeve 9c and the slider base 9a is a fixing connection structure which enables the first threaded sleeve 9c to be detachable relative to the slider base 9a, for example, the first threaded sleeve 9c and the slider base 9a are fixedly connected by bolts, so that the first threaded sleeve 9c is replaced according to actual conditions such as the abrasion condition of the first threaded sleeve 9c and the thread pitch of the first threaded sleeve 9 c.
A second mounting hole is formed in the other end of the sliding tool apron 2, a second threaded sleeve 10 in threaded connection with the middle of the screw rod 6 is arranged in the second mounting hole, and the second threaded sleeve 10 is fixedly connected with the sliding tool apron 2, so that threaded connection between the middle of the screw rod 6 and the sliding tool apron 2 is achieved. The fixing structure between the second threaded sleeve 10 and the sliding tool holder 2 is a fixing connection structure which enables the second threaded sleeve 10 to be detachable relative to the sliding tool holder 2, and if the second threaded sleeve 10 is fixedly connected with the sliding tool holder 2 through a bolt, the second threaded sleeve 10 is replaced according to actual conditions such as the abrasion condition of the second threaded sleeve 10 and the thread pitch of the second threaded sleeve 10.
A shaft sleeve 11 is sleeved on a rotating shaft 7b of the motor 7, the shaft sleeve 11 is fixedly connected with the rotating shaft 7b through a bolt, the other end of the screw rod 6 penetrates into the shaft sleeve 11, the other end of the screw rod 6 is circumferentially positioned and connected with the shaft sleeve 11, for example, a strip-shaped positioning hole is formed in the inner wall of the shaft sleeve 11 along the axial direction of the shaft sleeve, and the other end of the screw rod 6 is provided with a convex body embedded into the positioning hole; thereby achieving connection between the other end of the screw 6 and the rotating shaft 7b of the motor 7.
The action and the advantages of each part are further explained by explaining the process that the dynamic shearing die 4 and the material lifting slide block 9 clamp the metal bar 5 and release the sheared metal workpiece: the shearing oil cylinder of the metal bar material cutting machine pushes the sliding cutter holder 2 to move, so that the overlapped part between the inner hole of the movable shearing die 4 and the inner hole of the static shearing die 3 is less and less. In this process, if the motor 7 is the hydraulic motor 7, the hydraulic motor 7 communicates with the shear cylinder to rotate the rotary shaft 7b of the hydraulic motor 7 in the forward direction, and if the motor 7 is the electric motor 7 or the pneumatic motor 7, the shear cylinder operation is detected by a sensor, and the forward rotation of the rotary shaft 7b of the electric motor 7 or the pneumatic motor 7 is controlled by a control circuit. The rotating shaft 7b drives the screw rod 6 to rotate, and due to the threaded connection between the screw rod 6 and the material lifting sliding block 9 and the threaded connection between the screw rod 6 and the sliding tool holder 2, and the opposite spiral directions, the screw rod 6 moves axially relative to the sliding tool holder 2, the screw rod 6 moves axially relative to the material lifting sliding block 9, and the screw rod 6 moves axially relative to the shaft sleeve 11. The distance between the material lifting slide block 9 and the motor 7 is increased, the distance between the material lifting slide block 9 and the dynamic shearing die 4 is reduced, and the dynamic shearing die 4 and the material lifting slide block 9 clamp the metal bar 5 before the metal bar is sheared by the dynamic shearing die 4 and the static shearing die 3.
In the process of shearing the metal bar by the dynamic shearing die 4 and the static shearing die 3, the threaded connection structure has a self-locking characteristic, so that the possibility of reverse rotation of the screw 6 due to the retreating acting force of the material lifting slider 9 is obviously reduced. The motor 7 is controlled to output torque in the process of shearing the metal bar by the dynamic shearing die 4 and the static shearing die 3, so that the possibility of reverse rotation of the screw 6 due to the retreating acting force of the material lifting slide block 9 can be further reduced. The retreating force of the material lifting slide block 9 acts on the sliding tool apron 2 in the process of shearing the metal bar by the dynamic shearing die 4 and the static shearing die 3, so that the motor 7 is effectively protected.
After the metal bar is sheared by the dynamic shearing die 4 and the static shearing die 3, the shearing oil cylinder pulls the sliding tool apron 2 to move, the rotating shaft 7b of the motor 7 drives the screw rod 6 to rotate reversely, the screw rod 6 enables the distance between the material lifting slide block 9 and the motor 7 to be reduced, namely the distance between the material lifting slide block 9 and the dynamic shearing die 4 is increased, and the metal bar 5 is released.
