[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a metal material processing machine for bending and crushing a metal wire or a metal bar.

[0002]

[Prior art]

 In general, metal wires and metal rods were processed by a manual method, a method using a dedicated jig, or a method using an NC machine. The most common method using manual work is to use a vise, etc., in which a metal wire or a metal rod is fixed with a vise and then bent or crushed by hand or a tool.

A method using a dedicated jig uses a processing jig as shown in FIG. 4, so that a metal rod as a workpiece W is brought into contact with guides 31 and 31 ′ of a main body 30. After being fixed by the holding lever 32, the bending handles 33, 33 'are rotated by hand, and the metal rod is bent by bending bearings 34, 34' attached to the bending handles 33, 33 '.

The method of using an NC machine uses a fully automatic forming machine or a bender machine (not shown). The machine performs all processes from material supply to removal after processing under the control of a computer. It is expensive and can be processed in large quantities.

[0005]

[Problems to be solved by the invention]

 However, the conventional metal material processing apparatus described above has the following problems. In the manual processing method, there was variation in the work depending on the person performing the processing work, and there was a problem in the processing accuracy and the processing quantity was limited. The method using a dedicated jig is advantageous in terms of machining accuracy and machining quantity compared to manual work, but since it is a machining work that is performed manually, the machining accuracy decreases when the worker becomes tired. There was a problem that the processing quantity fell. The method using an NC machine is excellent in processing accuracy and processing quantity, but its price is high in the millions to tens of millions, and it requires considerable knowledge to handle it and can be easily introduced. However, there is a problem in the correction of curled materials such as coil materials.

[0006] The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to be able to accurately process a metal wire or a metal rod having a complicated shape, and to improve productivity. This is to provide a dedicated machine for processing metal materials that is expensive and is overwhelmingly cheaper than NC machines.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention relates to a metal processing machine dedicated to bending or crushing a rod-shaped or linear metal workpiece in which two independent processing stages are connected on the same plane. A guide plate fixed to a base plate to guide the workpiece, a fixed die fixed to the base plate, a bending die fixed to a turntable, and rotating the turntable. And a slide mechanism. The slide mechanism is an air cylinder, an arm having one end attached to a rod of the air cylinder, and the other end attached to the turntable, and an air controller for controlling air supplied to the air cylinder.

[Embodiment of the invention]

 Hereinafter, an embodiment of a metal material processing machine according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the metal material processing machine of the present invention, FIG. 2 is a side view of a partial cross section of the metal material processing machine of FIG. 1, and FIG. 3 is processing of the metal material processing machine of FIG. It is a schematic diagram which shows a process.

As shown in FIGS. 1 and 2, the dedicated machine for processing metal material according to the present invention has two independent processing stages A and A ′ connected and fixed by a connecting member C on the same plane. The two processing stages A and A 'have the same structure and are formed symmetrically to the left and right, and are fixed to the base plates 1 and 1' and guide plates 2 and 2 'for guiding the workpiece W and side gauges 3 and 3. 3 ', fixed bearing plates 4, 4' fixed to the base plates 1, 1 ', bending dies 6, 6' fixed to turntables 5, 5 ', and turntables 5, 6'. And slide mechanisms 20 and 20 'for rotating 5'. The operation of the slide mechanisms 20 and 20 'causes the turntables 5 and 5' to rotate and the bending dies 6 and 6 'to move. Bending metal rods and wires that are workpieces W This is to perform the work or crushing.

Further, in this machine for processing metal materials, the angles of the two processing stages A and A ′ with respect to the plane can be adjusted by releasing the connecting member C 2 as shown in FIG. In addition, the workpiece W can be bent not only on the same plane but also at a predetermined angle.

Further, a take-out lever 7 for taking out the processed workpiece W is attached to the metal material processing machine, so that the workpiece W can be easily taken out. Sensors 8 and 8 'are attached by two optical fibers to detect the set position of the workpiece W. If the workpiece W is not set properly, a display lamp 12 of the controller 10 described later is turned on. Without this, processing defects are prevented. As shown in FIG. 2, a base metal plate 15 is attached to the lower part of the machine dedicated to metal material processing, so that the machine dedicated to metal material processing can be installed on the work bench 16 or the like.

The metal material processing machine is provided with a counter 9 for counting the number of processed workpieces W. The counter 9 counts the number of operations of the air cylinder 21 as a processing quantity of the workpiece W by counting up. In order to make it clear that the workpiece W has been processed, a check marker 13 is attached, and the workpiece W that has been processed normally is marked by the tip of the check marker 13 contacting it. Is what is done. The processed marking may be engraved.

Further, the control box 10 for operating the metal material processing machine is provided with a start button 11 and an indicator lamp 12, and when the start button 11 is pressed, the apparatus operates. The display lamp 12 is turned on only when the workpiece W is correctly set by the sensors 8, 8 ', and the operator only needs to turn on the start button 11 when the display lamp 12 is turned on. The structure is designed to prevent machining defects.

Next, since the two processing stages A and A ′ have the same structure, the structure of the processing stage A will be mainly described. The base plate 1 is formed of a steel plate having a predetermined thickness. An operation hole 1a of the movable die 6 is formed near the center, and the turntable 5 is rotatable below the operation hole 1a. Has been fitted. Further, screw holes are formed at predetermined positions of the base plate 1 so that the guide plate 2, the side gauge 3, and the bearing plate 4 can be attached, and the guide plate 2, the side gauge 3, and the bearing plate 4 are respectively attached. I have.

The guide plate 2 is attached to the base plate 1 with mounting screws, and includes an upper guide plate 2a and a lower guide plate 2b. The workpiece W is sandwiched between the upper guide plate 2a and the lower guide plate 2b from both sides. Therefore, the upper guide plate 2a is movable so that the distance between the upper guide plate 2a and the lower guide plate 2b can be adjusted according to the thickness of the workpiece W, and the upper guide plate 2a is guided. It is designed to be supported by the plate holder 2c. In addition, since the lower guide plate 2b also serves as a bending guide for the workpiece W, it can also be adjusted in the length direction of the workpiece W.

The side gauge 3 guides the workpiece W in the longitudinal direction, and determines the inner distance between the processing stage A and the side gauges 3 and 3 ′ of the processing stage A ′ by the length of the workpiece W. It can be adjusted accordingly. The bearing plate 4 has a bearing 4a attached to a tip end side (workpiece W side) of a plate attached to the base plate 1 with attachment screws. A guide groove (not shown) is formed in the bearing 4a so that the workpiece W can move smoothly along the guide groove when the tip position moves during bending.

The turntable 5 is rotatably fitted in an operation hole a formed in the base plate 1. As shown in FIG. 2, the turntable 5 is rotatably supported by a turntable guide 5a fixed to the base plate 1 by two upper and lower bearings 5b and 5c. One end of an arm 23 is connected to the turntable 5, and the other end of the arm 23 is connected to a tip of a rod 22 of the air cylinder 21. Then, the turntable 5 is rotated by the sliding operation of the air cylinder 21.

Next, the operation of the slide mechanism will be described with reference to FIG. First, FIG. 3A shows a start state. In this state, the rod 22 of the air cylinder 21 is retracted, and the turntable 5 is also rotated to the initial position by the arm 23. The bending die 6 is retracted to a position where it does not hit the workpiece W. The workpiece W before bending is in a linear state, and both ends of the workpiece W are guided by the side gauges 3, 3 '. The workpiece W is also guided and fixed in the radial direction by the guide plates 2a and 2b. In this state, the set state is checked by the sensors 8 and 8 ', and if it is normal, the display lamp 12 is turned on.

Next, when the start button is pressed, the air controller 24 operates and air is sent to the air cylinder 21 as shown in FIG. 3B, and the rod 22 moves forward. Then, the turntable 5 is rotated clockwise by the arm 23, and the bending die 6 starts bending the workpiece W. The workpiece W is set to have a predetermined bending dimension at a full stroke position of the air cylinder 21.

Next, as shown in FIG. 3B, when the air cylinder 21 reaches the full stroke position, the air controller 24 operates to switch the air circuit (not shown) to move the rod 22 of the air cylinder 21 to the initial state. Retract to position. Then, since the arm 23 also retreats, the turntable 5 rotates counterclockwise, and the bending die 6 returns to the initial position. Then, the worker takes out the workpiece W with the take-out lever 7 and ends the bending.

The metal material processing machine configured as described above employs a small slide mechanism, so that metal materials such as metal wires and metal rods can be bent and crushed with high precision similarly to the NC machine. Despite this, the price is 1/10 that of an NC machine, making it extremely low.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various embodiments can be made within the scope of the utility model registration claims. For example, a ball screw mechanism using a motor instead of an air cylinder for the slide mechanism can be employed. Further, in the above-described embodiment, the case where the two independent stages A and A 'have the same structure has been described. However, even when the two independent stages A and A' do not have the same structure, it is possible to do so. Of course.

[0024]

[Effect of the invention]

 As described above, the present invention is directed to a machine dedicated to metal material processing in which two independent processing stages are connected on the same plane to bend or crush a rod-shaped or linear metal material. A guide plate and a side gauge fixed to the base plate and guiding the metal bar; a fixed type fixed to the base plate; a movable type fixed to the turntable; and a slide for rotating the turntable. With the means, it is possible to provide a dedicated metal processing machine with high accuracy, low cost, and excellent productivity.

Further, the slide means includes an air cylinder, an arm having one end attached to a rod of the air cylinder, and the other end attached to the turntable, and an air for controlling air supplied to the air cylinder. By using the controller, a relatively small and inexpensive air cylinder can be used to rotate the turntable with a large torque, so that highly accurate machining can be efficiently performed. Furthermore, since the two processing stages can adjust the angle relative to each other, not only bending processing in the same plane but also bending processing in which the bending portion has a relative angle with respect to the central axis can be performed. The effect is that processing can be performed.
