Description

[Technical Field]

[0001] The present invention relates to a horizontal multistage pressure molding machine and a receiving and holding mechanism that can be attached to a horizontal multistage pressure molding machine. [Background technology]

[0002] A horizontal multi-stage pressure molding machine is configured to include a plurality of pressure molding stations arranged side by side on a machine base, each consisting of a die and a punch, a material cutting cutter provided on one side of the machine base as a cutting means for cutting rod-shaped material to a predetermined length, and a transfer device for transferring the material to be processed cut by the cutter between the pressure molding stations.The rod-shaped material supplied from one side of the machine base is cut to a predetermined length by the cutter, and the cut blanks are pressure molded in succession in stages in a plurality of pressure molding stations consisting of opposing dies and punches.

[0003] At the start of the work, to prevent any missing parts from occurring during forging and to ensure that the striking surface of the punch can be struck accurately, the cut blanks cut in advance by the cutter are removed without being sent to the forging station, and the shape, length, weight, etc. of the cut surface of the cut blanks are inspected.

[0004] A conventional machine has the following configuration: That is, a chute is provided below the die and punch, at an angle that allows the cut blanks to fall naturally and be discharged outside the machine while the machine is running, so that the operator can remove the cut blanks during inspection. That is, during inspection, when the cut blanks are transferred to the next process between the die and punch by a chuck-type transfer mechanism while the machine is running, the chuck of the chuck-type transfer mechanism is opened by remote control to drop the cut blanks, the falling cut blanks are received by the chute, and the transfer conveyor transports them to the other side of the machine base, and the blanks are then guided downward via the chute toward a tray, which is then raised and lowered to the top of the machine base (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-288679 Summary of the Invention [Problem to be solved by the invention]

[0006] The above-described conventional configuration has disadvantages such as requiring cumbersome operations such as moving the cut blank over a long distance or lifting it to the top of the machine. Furthermore, when inspecting the cut blank, if a test sample is obtained after repeating the cutting operation multiple times, there is a disadvantage that it may be difficult to distinguish whether the cut blank is the test blank obtained by the test or the cut blank intended as the test sample, and improvements have been desired.

[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a horizontal multistage forging machine that can easily inspect cut blanks without any hassle. [Means for solving the problem]

[0008] The characteristic configuration of the horizontal multi-stage pressure forming machine of the present invention is that it is a horizontal multi-stage pressure forming machine equipped with a plurality of rolling stations arranged side by side on a machine base, each consisting of a die and a punch, a cutting means provided on one side of the machine base for cutting a rod-shaped material into workpieces of a predetermined length, and a transfer means for sequentially transferring the workpieces to the plurality of rolling stations, and is equipped with a receiving and holding mechanism for receiving and holding cut blanks that are cut from the workpieces by the cutting means and discharged.

[0009] According to the present invention, when inspecting cut blanks, after the rod-shaped material is cut to a predetermined length by the cutting means, the discharged cut blanks can be received and supported by the receiving and holding mechanism. An operator can then remove the cut blanks supported by the receiving and holding mechanism and inspect the shape, length, weight, etc. of the cut surface of the cut blanks. When the cut and discharged cut blanks are to be received by the receiving and holding mechanism, the operation of the transporting means can be stopped or the transporting means can be removed in advance.

[0010] As a result, there is no need to move the cut blank over a long distance or lift it up to the top of the machine, and this can be done with a small device, making it easy to avoid making the configuration complicated.In addition, the operator only needs to remove the cut blank that is cut by the cutting means and then discharged, eliminating the need for cumbersome work.

[0011] Therefore, it has become possible to provide a horizontal multistage heading molding machine that can easily inspect cut blanks without any hassle.

[0012] In the present invention, it is preferable that the receiving and holding mechanism is provided with a receiving member capable of receiving the cut blank, and that the receiving member is configured to be switchable between an active state in which it is positioned within the downward drop area of ​​the cut blank, and a standby state in which it is retracted outside the downward drop area.

[0013] According to this configuration, when the receiving and holding mechanism is in an active state, the receiving member is located within the downward drop area of ​​the cut blanks, so that the discharged cut blanks can be received properly. On the other hand, when cutting work is performed without receiving the cut blanks, such as when a test run of the cutting means is being performed, by switching the receiving and holding mechanism to a standby state, the receiving and holding mechanism is retracted outside the downward drop area, so that the cut and discharged cut blanks can be prevented from colliding with and damaging the receiving and holding mechanism.

[0014] In the present invention, it is preferable that the receiving member has a recessed groove extending along the longitudinal direction of the cut blank.

[0015] According to this configuration, the cut blank is received in a position in which its longitudinal direction is aligned with the recessed groove, and therefore can be received in a stable and favorable state.

[0016] In the present invention, it is preferable that the receiving and holding mechanism be switchable between the active state and the standby state by swinging the receiving member about a horizontal axis.

[0017] With this configuration, the position of the receiving member is changed by swinging, which makes the switching operation easy and smooth. In addition, since the receiving member swings around a horizontal axis, the position can be changed by moving it vertically and horizontally in one go, so the position can be changed appropriately without any hassle.

[0018] In the present invention, it is preferable that the horizontal axis is an axis along the longitudinal direction of the cut blank.

[0019] According to this configuration, the receiving member moves while maintaining its orientation along the longitudinal direction of the cut blank, and therefore the orientation of the receiving member does not change as it swings, making it easy to stabilize its orientation.

[0020] In the present invention, it is preferable that the receiving and holding mechanism is provided with a receiving actuator that can be switched between the active state and the standby state.

[0021] According to this configuration, by using the actuator, the receiving and holding mechanism can be easily and quickly switched between the active state and the standby state without the hassle of manually switching.

[0022] In the present invention, it is preferable that a protective member be provided to prevent the cut blank from falling toward the receiving and holding mechanism when the receiving and holding mechanism is switched to the standby state.

[0023] According to this configuration, even if the cut blank that has been cut and discharged falls downward toward the receiving and holding mechanism in a standby state, the cut blank is received by the protective member, thereby reliably preventing damage to the receiving and holding mechanism.

[0024] In the present invention, it is preferable that the protective member be movable by swinging around a horizontal axis between a fall prevention position that prevents the cut blank from falling toward the receiving and holding mechanism, and a retracted position that allows the receiving and holding mechanism to switch from the standby state to the active state.

[0025] According to this configuration, by moving the protective member to the retracted position, the protective member does not prevent the receiving and holding mechanism from changing its position, and the receiving and holding mechanism can be smoothly switched from the standby state to the active state.

[0026] In the present invention, it is preferable that a protection actuator is provided that can switch the protection member between the fall prevention position and the retracted position.

[0027] According to this configuration, by using the actuator, the protective member can be easily and quickly switched between the fall prevention position and the retracted position without the hassle of manually switching.

[0028] In the present invention, it is preferable that the receiving and holding mechanism is provided with a weight measuring means for measuring the weight of the cut blank.

[0029] When the receiving and holding mechanism receives and holds the cut blank, the weight of the cut blank can be measured by the weight measuring means, so that the worker does not have to take the trouble of measuring the weight of the cut blank when inspecting it, thereby improving work efficiency.

[0030] In the present invention, it is preferable that the receiving and holding mechanism comprises a receiving member that receives the cut blank and a support arm that supports the receiving member, and that the weight measuring means comprises a load cell positioned between the receiving member and the support arm.

[0031] According to this configuration, the load cell can directly measure the combined weight of the receiving member and the cut blank, and the weight of the cut blank can be measured with high accuracy.

[0032] The receiving and holding mechanism of the present invention is a receiving and holding mechanism that can be attached to a horizontal multi-stage pressure molding machine that is equipped with a plurality of rolling stations arranged side by side on a machine base, each consisting of a die and a punch, a cutting means provided on one side of the machine base for cutting a rod-shaped material into workpieces of a predetermined length, and a transfer means for sequentially transferring the workpieces to the plurality of rolling stations, and that receives and holds cut blanks that are cut from the workpieces by the cutting means and discharged.

[0033] The receiving and holding mechanism according to the present invention can be attached externally to the horizontal multistage pressure molding machine. When inspecting cut blanks, the rod-shaped material is cut to a predetermined length by the cutting means, and the cut blanks discharged can be received and supported by the receiving and holding mechanism. An operator can then remove the cut blanks supported by the receiving and holding mechanism and inspect the shape, length, and weight of the cut surfaces of the cut blanks. When the cut and discharged cut blanks are to be received by the receiving and holding mechanism, the operation of the transport means can be stopped, or the transport means can be removed in advance.

[0034] As a result, there is no need to move the cut blank over a long distance or lift it to the top of the machine, and this can be done with a small device, making it easy to avoid making the configuration complicated.In addition, the operator only needs to remove the cut blank that is cut by the cutting means and then discharged, eliminating the need for cumbersome work.

[0035] Therefore, it has become possible to provide a receiving and holding mechanism that allows inspection of cut blanks to be easily performed without cumbersomeness, without complicating the configuration of the horizontal multistage pressure molding machine.

[Figure 2] 1 is a vertical sectional front view showing a schematic configuration of a horizontal multistage pressure molding machine. FIG. [Figure 3] FIG. [Figure 4] FIG. 10 is a front view showing the receiving and holding mechanism in an operative state. [Figure 5] FIG. 10 is a front view showing the receiving and holding mechanism in a standby state. DETAILED DESCRIPTION OF THE INVENTION

[0037] Hereinafter, an embodiment of a horizontal multistage pressure molding machine according to the present invention will be described with reference to the drawings. Note that the present invention is not limited to the following embodiment, and various modifications are possible without departing from the spirit and scope of the present invention.

[0038] 1 and 2, the horizontal multistage pressure molding machine has a die block 3 fixed at a predetermined position on a machine base 2, and a ram 4 that can move forward and backward between a state of approaching the die block 3 and a state of moving away from the die block 3. A plurality of dies 5 are fixed in front of the die block 3 and arranged side by side at regular intervals.

[0039] On the other hand, a plurality of punches 6 are fixed in a line at regular intervals in front of the ram 4, facing each of the dies 5, and a plurality of heading stations are formed by these opposing punches 6 and dies 5. The ram 4 moves back and forth between a state where it approaches the die block 3 and a state where it is separated from the die block 3 by rotating a crankshaft 7 with a motor 8.

[0040] As shown in Figure 2, one side of the die block 3 is provided with a material supply section 9 for supplying a rod-shaped material X made of wire to a forging station consisting of a die 5 and a punch 6, a cutting cutter 10 as cutting means for cutting the supplied rod-shaped material X into workpieces of a predetermined length, and a pusher 11 (see Figure 3) for pushing the workpieces A cut by the cutter 10 out of the cutter 10.

[0041] 2, a chuck-type transfer device 12 is provided above the die block 3 as a transfer means for sequentially transferring the workpiece A to each forging station. This transfer device 12 is configured to include a cut blank clamping chuck 12a that transfers the cut blank A1 that is cut from the workpiece A by the cutter 10 and discharged, and multiple semi-formed product or final formed product clamping chucks 12b to 12d. Normally, each chuck moves between adjacent forging stations in synchronization with the forward and backward movement of the ram 4, and the cut blank A1 is clamped by the cut blank clamping chuck 12a, and the semi-formed product or final formed product is clamped by the semi-formed product or final formed product clamping chucks 12b to 12d, and the cut blank A1 is sequentially transferred downstream.

[0042] The semi-formed products or final formed products forged at each forging station are ejected from each die 5 by a pusher 11 installed inside each die 5, and are received by each chuck 12a to 12d of the transfer device 12.

[0043] On the other hand, on the other side of the machine base 2, there is provided a work table 14 having an operation unit 13 for remotely operating each operating device such as the material supply unit 9, cutter 10, transfer device 12, ram 4, etc. A transfer conveyor 16 is provided to transfer the final formed product that has been formed by forging in the final forging station and removed by the final formed product clamping chuck 12d of the transfer device 12 to a product recovery unit 15.

[0044] The material A to be processed cut by the cutter 10 is then transported in sequence to each forging station by the transfer device 12, where it is forged in stages, and is then molded into a product of a predetermined shape (final molded product) at the final forging station.

[0045] Below the cutting point by the cutter 10 and below the points corresponding to each forging station, a receiving table 17 is provided to receive, hold, and recover the material to be processed if it falls downward.

[0046] [Receiving and holding mechanism] The horizontal multistage heading molding machine 1 of this embodiment is provided with a receiving and holding mechanism 18 that receives and holds the cut blank A1 that is cut by the cutter 10 and discharged from the workpiece.

[0047] 3 and 4, the receiving and holding mechanism 18 is provided with a receiving member 19 capable of receiving the cut blank A1. The receiving member 19 has a recessed groove 20 that is recessed in the center along the longitudinal direction of the cut blank A1. That is, as shown in FIGS. 3 and 4, the receiving member 19 has a substantially V-shaped cross section in a side view, and is provided so as to extend along the longitudinal direction of the cut blank A1, i.e., the protruding direction of the cut blank A1.

[0048] The receiving and holding mechanism 18 is configured to be switchable between an active state in which the receiving member 19 is positioned within the downward drop area of ​​the cut blanks A1 and a standby state in which the receiving member 19 is retracted outside the downward drop area. The receiving and holding mechanism 18 can be switched between the active state and the standby state by swinging the receiving member 19 around the horizontal axis.

[0049] That is, the receiving member 19 is supported on one end of a pair of left and right support arms 21, and the base end of each of the pair of support arms 21 is fixed to a rotating boss member 22. A horizontally extending shaft member 23 is provided and fixed to the machine base 2, and the rotating boss member 22 is rotatably fitted onto the outside of the shaft member 23. Therefore, the receiving member 19 is supported on the machine base 2 so as to be rotatable about the horizontal axis P1 of the shaft member 23, which is the axis that runs along the longitudinal direction of the cut blank A1, i.e., the direction in which the cut blank A1 projects.

[0050] The receiving and holding mechanism 18 is provided with a first air cylinder 24 as a receiving actuator that can be switched between an active state and a standby state. An operating arm 25 is provided that is integrally connected to the base end of one of the support arms 21 and extends radially outward from the shaft member 23. The first air cylinder 24 is provided to extend in the vertical direction, with one end of the first air cylinder 24 pivotally connected to the radially outer end of the operating arm 25 and the other end of the first air cylinder 24 connected to the machine base 2 via a first support member 26.

[0051] 4 and 5, by operating the first air cylinder 24 to extend or retract, the receiving member 19 can be switched between an active state (FIG. 4) in which it is positioned to receive the cut blanks A1 discharged from the die block 3, and a standby state (FIG. 5) in which it retracts to the back of the lower space. In the active state, the receiving member 19 is positioned within the downward drop area of ​​the cut blanks A1, and in the standby state, the receiving member 19 is retracted outside the downward drop area of ​​the cut blanks A1.

[0052] [Protective member] A protective member 28 is provided to prevent the cut blanks A1 from falling toward the receiving and holding mechanism 18 when the receiving and holding mechanism 18 is switched to a standby state. The protective member 28 can swing about a horizontal axis to move between a fall prevention position that prevents the cut blanks A1 from falling toward the receiving and holding mechanism 18 and a retracted position that allows the receiving and holding mechanism 18 to switch from the standby state to the active state.

[0053] The protective member 28 has a receiving portion 28a made of a rectangular plate, and left and right strip-shaped side wall portions 28b connected to the left and right ends of the receiving portion 28a in a vertical position. The left and right side wall portions 28b are supported by the machine base 2 via support brackets 29 so as to be rotatable about a horizontal axis P2 at their midpoints in the longitudinal direction. Therefore, the protective member 28 is supported by the machine base 2 so as to be rotatable about the horizontal axis P2 as the rotation axis, and is configured to be movable between a fall prevention position and a retracted position by rotating.

[0054] A second air cylinder 30 is provided as a protective actuator that can switch the protective member 28 between a fall prevention position and a retracted position. The second air cylinder 30 is provided to extend horizontally, with one end of the second air cylinder 30 pivotally connected to a location slightly below the horizontal axis P2 for rotation of the protective member 28, and the other end of the second air cylinder 30 pivotally connected to a second support member 31 fixed to the machine base 2.

[0055] When the receiving and holding mechanism 18 is switched to the active state, the second air cylinder 30 is retracted to switch the protective member 28 to the retracted position. When the receiving and holding mechanism 18 is in the standby state, the second air cylinder 30 is extended to switch the protective member 28 to the fall prevention position.

[0056] One of the pair of left and right support arms 21 in the receiving and holding mechanism 18 is provided at a shifted position on the side of the protective member 28. The other support arm 21 is positioned so as to overlap the protective member 28. For this reason, a slit 28c (FIG. 3) is formed in the protective member 28 to allow the other support arm 21 to swing. When the state of the receiving and holding mechanism 18 is switched, the other support arm 21 enters the slit 28c and swings.

[0057] By providing the protective member 28, even if the cut blank A1 falls downward after being cut by the cutter 10 while the receiving and holding mechanism 18 is in a standby state, it is possible to prevent the cut blank A1 from colliding with and damaging the receiving and holding mechanism 18. Furthermore, by switching the protective member 28 to the retracted position, the receiving member 19 of the receiving and holding mechanism 18 will not interfere with the protective member 28 and hinder its movement.

[0058] [Detachable configuration] The receiving and holding mechanism 18 can be retrofitted to a horizontal multistage heading molding machine. That is, the receiving and holding mechanism 18 can be separately installed on an existing horizontal multistage heading molding machine that does not have the receiving and holding mechanism 18 installed.

[0059] More specifically, support brackets 29 on both the left and right sides that support shaft member 23, which integrally supports receiving member 19 and support arm 21 so that they can rotate together, and that rotatably support protective member 28, can be attached to machine base 2 with bolts. In addition, first support member 26 that supports the base end of first air cylinder 24 and second support member 31 that supports the base end of second air cylinder 30 are configured to be fixed to machine base 2 with bolts.

[0060] Therefore, by attaching the support brackets 29 on both the left and right sides that support the shaft member 23 and the protective member 28 to the machine base 2, and attaching the first support member 26 and the second support member 31 to the machine base 2, it is possible to attach the receiving and holding mechanism 18 to the horizontal multi-stage pressure molding machine 1 in an after-market state.

[0061] [Taking a sample of cutting blank A1] At the start of the operation of carrying out the continuous forging process, the cut blank A1 cut by the cutter 10 is removed in advance as an inspection sample using the receiving and holding mechanism 18 without being sent to the forging station, and the shape, length, weight, etc. of the cut surface of the cut blank A1 are inspected. When such an inspection is carried out, the transfer device 12 is kept in an open state or is removed.

[0062] When collecting the cut blank A1 using the receiving and holding mechanism 18, the operator operates the operating unit 13 to perform an inspection sample collection operation that only involves cutting by the cutter 10 and pushing out the cut blank A1. When performing the inspection sample collection operation, the cutter 10 performs two trial cutting processes (blank cuts), and then the operator collects the cut blank A1 that was cut the third time and inspects the shape, length, weight, etc. of the cut surface of the cut blank A1.

[0063] The operating unit 13 is provided with a first operating device 32 that commands a single operation of the material supply unit 9, cutter 10, and pusher 11, and a second operating device 33 that switches the receiving and holding mechanism 18 between a standby state and an active state. When performing a test sample acquisition operation, the operator operates the first operating device 32 twice in succession. Operating the first operating device 32 once performs the following operations: feeding of material X by the material supply unit 9, cutting processing by the cutter 10, and pushing out the cut blank A1 after cutting by the pusher 11. The pushed-out cut blank A1 falls downward and is received by the receiving table 17.

[0064] Next, the operator operates the second operating device 33 to switch the receiving and holding mechanism 18 from the standby state to the operating state, and then operates the first operating device 32 a third time. As a result, the cut blank A1 after being cut is pushed out by the pusher 11 and received and held by the receiving member 19 of the receiving and holding mechanism 18. The operator manually picks up the cut blank A1 received and held by the receiving member 19 using a hand magnet (not shown) or the like, and performs the above-mentioned inspection.

[0065] [Another embodiment] (1) In the above embodiment, the receiving member 19 is configured to be switchable between an operating state and a standby state by swinging about a horizontal axis along the longitudinal direction of the cut blank A1, but instead of this configuration, the receiving member 19 may be configured to swing about a horizontal axis along a direction different from the longitudinal direction of the cut blank A1, or the receiving member 19 may be configured to be switchable between an operating state and a standby state by swinging about a vertical axis. Also, the receiving member 19 may be configured to slide horizontally to be switchable between an operating state and a standby state, and various other configurations can be adopted.

[0066] (2) In the above embodiment, the receiving member 19 is configured to be switchable between an active state in which it is located within the downward drop area of ​​the cut blank A1 and a standby state in which it is retracted outside the downward drop area, but this configuration is not limited thereto, and the receiving member 19 may also be always located in the active state.

[0067] (3) In the above embodiment, the receiving member 19 is configured to have a recessed groove along the longitudinal direction of the cut blank A1. However, instead of this configuration, it can be implemented in various forms, such as a configuration having a circular or rectangular recess.

[0068] (4) In the above embodiment, the receiving and holding mechanism 18 is configured to be equipped with the first air cylinder 24 as a receiving actuator, but instead of this configuration, a hydraulic cylinder, an electric cylinder, etc. may be used as the receiving actuator.

[0069] (5) In the above embodiment, the second air cylinder 30 is provided as a protective actuator capable of switching the protective member 28. However, instead of this configuration, a hydraulic cylinder, an electric cylinder, or the like may be used as the protective actuator.

[0070] (6) In the above embodiment, the receiving member 19 is fixedly supported on the support arm 21. However, instead of this configuration, the receiving member 19 may be supported so as to be slidable in the vertical direction relative to the support arm 21, and a load cell may be provided between the receiving member 19 and the support arm 21 as a weight measuring means for measuring the weight of the cut blank A1. In this case, it is preferable to automatically perform zero point correction when measuring the weight to reduce measurement errors. In addition to this configuration, a torque sensor or the like provided at the base end of the support arm 21 may also be used as the weight measuring means.

[0071] (7) In the above embodiment, the operating unit 13 is configured to include a first operating device 32 that commands a single operation of the material supply unit 9, the cutter 10, and the pusher 11, and a second operating device 33 that switches the receiving and holding mechanism 18 between a standby state and an active state. However, instead of this configuration, a single operating device may be configured to execute a series of operations in one go, such as executing the above-mentioned operations of feeding, cutting, and pushing out (blank shot) twice, switching the receiving and holding mechanism 18 from the standby state to the active state, and further executing the operations of feeding, cutting, and pushing out (sample collection) once. Only one blank shot may be performed. [Industrial Applicability]
