Further, how to provide a processing device capable of linking the preamble step and the subsequent heat treatment step, so as to realize full automation of the preamble step and the subsequent heat treatment step is still another technical problem faced by the prior art.

Disclosure of Invention

In view of the above problems, the present invention provides a processing apparatus capable of automatically heating both end portions of a rod-like material.

A first aspect of the present invention provides a processing apparatus for processing a rod-shaped material, comprising: the first ejector pin extends in parallel along the axial direction of the rod-shaped material; the second thimble is coaxially arranged with the first thimble, and the second thimble and the first thimble can be mutually close to/far away from each other; the heating coil is sleeved on the first thimble or the second thimble, and the first thimble and the second thimble are respectively abutted with the two end parts of the rod-shaped material, and when the two end parts of the rod-shaped material move along the same direction of the axis, the two end parts of the rod-shaped material can be sequentially arranged on the inner side of the heating coil.

According to the processing equipment provided by the invention, the processing equipment comprises the first thimble extending along the axial direction of the rod-shaped material and the second thimble coaxially arranged with the first thimble, and the rod-shaped material can be stably fixed by respectively abutting the first thimble and the second thimble with the two end parts of the rod-shaped material, so that the smooth proceeding of the heating process is ensured. Because the first thimble and the second thimble can be mutually close to/far away from each other, the first thimble and the second thimble can be used for fixing rod-shaped materials with different lengths, thereby realizing heating of the end parts of the rod-shaped materials with various lengths. And keep away from between first thimble and the second thimble, just can make the bar-shaped material after heating and first thimble and second thimble separation, be convenient for the quick unloading after the heating finishes, be favorable to improving the smoothness and the efficiency of whole heating step.

The first thimble extends in parallel along the axial direction of the rod-shaped material, which means that the first thimble has a length extending along the axial direction of the rod-shaped material. The second ejector pin also has a length extending in the axial direction of the rod-like material.

Preferably, the axis of the first thimble, the axis of the second thimble, the axis of the rod-shaped material, and the axis of the heating coil are all on the same straight line.

In the processing apparatus according to an alternative aspect of the present invention, further comprising: linear guide rails extending in parallel along the axial direction; the sliding block is connected with the linear guide rail and is connected with the first thimble or the second thimble.

According to the above preferred technical scheme, as the first ejector pin or the second ejector pin is connected with the linear guide rail through the sliding block, the moving direction of the first ejector pin or the second ejector pin can be guided, so that the first ejector pin or the second ejector pin is accurately abutted with the position, close to the center, of the end part of the rod-shaped material, and therefore the rod-shaped material is stably fixed, and the rod-shaped material driven by the ejector pin can smoothly pass through the heating coil without interference with the heating coil.

In the processing apparatus according to an alternative embodiment of the present invention, the heating coil is a high-frequency heating coil for heating both end portions of the rod-like material to an annealing temperature.

By the above preferred technical scheme, the high-frequency heating coil has high heating temperature and high heating speed, and is suitable for the annealing process of the end part of the rod-shaped material.

In the processing apparatus according to an alternative aspect of the present invention, further comprising: a lifting loading table which extends in parallel along the axis direction; and a third thimble and a fourth thimble which are respectively arranged at two ends of the feeding table and are coaxially arranged, and the fourth thimble is arranged in a mode of being close to/far away from the third thimble.

Through the above preferable technical scheme, the loading platform extending along the axis direction is included, so that the loading platform can bear rod-shaped materials under the condition of small occupied space. Because the rod-shaped material feeding device comprises the third thimble and the fourth thimble which are coaxially arranged, and the fourth thimble can be close to/far away from the third thimble, when the fourth thimble approaches to the third thimble, the third thimble and the fourth thimble can respectively abut against the two end parts of the rod-shaped material arranged on the feeding table, and the rod-shaped material is fixed at a specified position, so that the rod-shaped material feeding device is favorable for positioning and grabbing the rod-shaped material under the condition of optional automatic control. Since the loading table is liftable, when the rod-shaped material is fixed between the third ejector pin and the fourth ejector pin, by lowering the loading table, it is possible to stably hold the rod-shaped material in the direction perpendicular to the axis of the rod-shaped material under optional automatic control.

The lifting loading table is capable of descending in a linear motion or rotary motion mode to separate the loading table from the rod-shaped material originally placed on the loading table.

In the processing apparatus according to an alternative aspect of the present invention, further comprising: the carrying grabbing clamp capable of walking between the area where the third thimble and the fourth thimble are located and the area where the first thimble and the second thimble are located is provided with a material loading block and a material pressing block which are oppositely arranged in the direction perpendicular to the axis direction.

Through the above preferred technical scheme, because the carrying grabbing clamp is provided with the loading blocks and the pressing blocks which are oppositely arranged in the direction perpendicular to the axis, the rod-shaped material can be clamped more stably in the direction perpendicular to the axis of the rod-shaped material, so that the rod-shaped material is not easy to fall in the process of walking from the area where the third thimble and the fourth thimble are located to the area where the first thimble and the second thimble are located in the carrying grabbing clamp.

The area where the third thimble and the fourth thimble are located is an area where the carrying material loading block and the pressing block which are used for carrying the grabbing clamp can grab the rod-shaped material originally located on the feeding table from the position between the third thimble and the fourth thimble.

The area where the first thimble and the second thimble are located is an area where the carrying grabbing clamp can contact rod-shaped materials between the loading block and the pressing block with the end parts of the first thimble/the second thimble.

In the processing apparatus according to an alternative embodiment of the present invention, the surface of the loading table and/or the loading block for loading the rod-like material is provided with V-grooves. The V-shaped groove is a groove extending in the axial direction of the rod-shaped material and having a V-shaped cross section. Because the V-shaped groove is arranged, the rod-shaped material is not easy to roll when being loaded on the loading table or the loading block, so that the operation process of the processing equipment is more controllable.

In the processing apparatus according to an alternative aspect of the present invention, further comprising: a receiving groove which is arranged in a mode of extending out to receive the rod-shaped material which falls between the first thimble and the second thimble and retracting; and the pushing block slides in the receiving groove along the axis direction.

By the above preferred technical scheme, the rod-shaped material can be simply and rapidly stored and transferred after being heated due to the material receiving groove capable of extending and receiving the rod-shaped material and retracting and the pushing block sliding in the material receiving groove.

By including the liftable cooling basket in the cooling tank, the cooling basket and the rod-shaped materials therein can be immersed in the cooling liquid in the cooling tank together by descending the cooling basket, and the cooled rod-shaped materials can be taken out more easily by ascending the cooling basket. The wide edge of the transition plate is in butt joint with the receiving groove, so that the rod-shaped material can move onto the transition plate from the receiving groove under the pushing of the pushing block. Because one long side of the transition plate is in butt joint with the cooling basket, and the other long side of the transition plate is hinged with the periphery of the cooling tank, after the rod-shaped material is pushed onto the transition plate, the transition plate rotates around the hinge shaft after being acted by the gravity of the rod-shaped material above the transition plate, and the transition plate forms a slope along which the rod-shaped material falls into the cooling basket and is immersed into cooling liquid. Because the transition plate forms a slope, one side of the transition plate, which is in butt joint with the cooling basket, is close to the surface of the cooling liquid, so that the cooling liquid is not easy to splash when the rod-shaped material falls into the cooling liquid.

In the processing apparatus according to an alternative aspect of the present invention, further comprising: the feeding device is provided with a roller and a movable vice which are sequentially arranged along the feeding direction; the cutting device is provided with a fixed vice and a cutting tool arranged opposite to the fixed vice; the feeding jig transfers the rod-shaped material cut into a predetermined length to the feeding table.

According to the above preferred technical scheme, the roller and the movable vice are arranged, the movable vice can clamp the rod-shaped material and move along the feeding direction, and the rod-shaped material placed on the roller can be easily driven by the movable vice and move along the feeding direction. Due to the fixed vice and the cutting tool arranged opposite to the fixed vice, the fixed vice can clamp and stabilize the rod-shaped material, so that the cutting tool can stably cut the rod-shaped material, and the cutting precision is improved. The feeding clamp for transferring the rod-shaped material cut into the specified length to the feeding table is arranged, so that the preamble step and the subsequent heat treatment step can be connected, and the full automation of the preamble step and the subsequent heat treatment step is realized.

Preferably, the movable jaw is connected to the servo motor, in other words, the movable jaw is controlled by the servo motor, so that the accuracy of feeding can be improved, and thus the rod-shaped material can be cut within a tolerance range.

Preferably, both the fixed jaw and the cutting tool are connected to a servo motor, in other words, the fixed jaw and the cutting tool are controlled by the servo motor, so that the cutting accuracy can be improved, thereby ensuring the finish and verticality of the cut end face.

The second aspect of the present invention also provides a processing method, using the processing apparatus, comprising: a fixing step of enabling one end of the rod-shaped material to be abutted against the first thimble, and enabling the second thimble to move along the direction close to the first thimble and to be abutted against the other end of the rod-shaped material; and a heating step, wherein the first thimble and the second thimble are respectively abutted with two end parts of the rod-shaped material and move in the same direction along the axis direction, so that the two end parts of the rod-shaped material are sequentially arranged at the inner side of the heating coil.

In the processing method according to an alternative embodiment of the present invention, before the fixing step, the method further includes: a material taking step, namely enabling the fourth thimble to move along the direction close to the third thimble, contact with one end part of the rod-shaped material arranged on the feeding table and push the rod-shaped material, enabling the other end part of the rod-shaped material to be in contact with the third thimble, and enabling the feeding table to descend; and a carrying step, namely enabling the carrying grabbing clamp to move to the area where the third thimble and the fourth thimble are located, enabling the rod-shaped material to be placed between the carrying material block and the pressing material block of the carrying grabbing clamp, enabling the pressing material block to press down and clamp the rod-shaped material, and enabling the carrying grabbing clamp clamping the rod-shaped material to move to the area where the first thimble and the second thimble are located.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Fig. 1 is a schematic structural view of the processing apparatus provided in the present embodiment, showing a state in which the first thimble 11 and the second thimble 12 are away from each other. The processing apparatus shown in fig. 1 is for processing a rod-like material 10 and is capable of heating an end portion of the rod-like material 10, and includes: a first thimble 11 extending in parallel along the axial direction of the rod-like material 10; the second thimble 12 is coaxially arranged with the first thimble 11, and the second thimble 12 and the first thimble 11 can be mutually close to or far from each other; the heating coil 13 is sleeved on the first thimble 11, and is configured such that when the first thimble 11 and the second thimble 12 respectively contact with two ends of the rod-shaped material 10 and move in the same direction along the axis direction, the two ends of the rod-shaped material 10 can be sequentially placed inside the heating coil 13.

Since the rod-shaped material 10 includes the first thimble 11 extending in the axial direction of the rod-shaped material 10 and the second thimble 12 provided coaxially with the first thimble 11, the rod-shaped material 10 can be stably fixed by the first thimble 11 and the second thimble 12 respectively abutting against both end portions of the rod-shaped material 10, thereby ensuring smooth progress of the heating process. Since the first thimble 11 and the second thimble 12 can be moved closer to/away from each other, it is possible to fix the rod-shaped materials 10 of different lengths by the first thimble 11 and the second thimble 12, thereby heating the end portions of the rod-shaped materials 10 of various lengths. And the rod-shaped material 10 which is heated can be separated from the first thimble 11 and the second thimble 12 by keeping away the first thimble 11 and the second thimble 12, so that the quick unloading after the heating is finished is convenient, and the smoothness and the efficiency of the working procedure are improved.

The first thimble 11 extends in parallel along the axial direction of the rod-shaped material 10 means that the first thimble 11 has a length extending in the axial direction of the rod-shaped material 10. The second ejector pin 12 also has a length extending in the axial direction of the rod-like material 10. The lengths and shapes of the first and second pins 11 and 12 in the axial direction are not particularly limited as long as portions of the first and second pins 11 and 12 that are in contact with both end portions of the rod-like material 10 can be placed inside the heating coil 13, in other words, the maximum diameter length of the first and second pins 11 and 12 at least at portions near the end portions is smaller than the diameter length of the heating coil 13.

In the present embodiment, as shown in fig. 2, the first ejector pin 11 has a first ejector pin end 111, a first ejector pin stem 112 having the same diameter as the first ejector pin end 111, a first ejector pin tail 113 having a gradually increasing diameter, and a first ejector pin fixing portion 114. Wherein the first thimble end 111 is made of metallic copper and has a diameter smaller than that of the end of the rod-shaped material 10, and the first thimble end 111 is used for abutting with the end of the rod-shaped material 10. Since metallic copper has good heat conduction performance, the first thimble end 111 made of copper and having a smaller diameter is used to fix the end of the rod-shaped material 10, which is beneficial to ensure that each region of the end of the rod-shaped material 10 can be heated to a specific temperature, so that the heat treatment process of the end of the rod-shaped material 10 can be optimized. Referring to FIGS. 1 and 2, first needle mount 114 may be embedded within first needle mount 115 to function to mount first needle 11. First needle holder 115 may be coupled to a cylinder (not shown) that may urge first needle holder 115 to move in a direction away from second needle 12 in the axial direction, thereby enabling first needle 11 to move in the axial direction.

In this embodiment, the second thimble 12 has a length smaller than that of the first thimble 11, as shown in fig. 1. Since the heating coil 13 is fitted over the first pin 11 in the present embodiment, the first pin 11 needs to have a certain length. However, it is sufficient that the heating coil 13 is sleeved on the first thimble 11 or the second thimble 12, but it is preferable that the heating coil 13 is sleeved on a thimble with a longer length. In this embodiment, the length of the second thimble 12 may be smaller, so that the furthest distance between the first thimble 11 and the second thimble 12 may be increased, so that the first thimble 11 and the second thimble 12 may be used to fix the rod-shaped material 10 with a longer length. With continued reference to FIG. 1, second needle 12 is fixed to one end of second needle mount 121, and the other end of second needle mount 121 is connected to a cylinder (not shown) so that second needle 12 can move in the axial direction. The second ejector pin holder 121 is connected to the slider 15 on the linear guide 14. In this way, the movement of the second thimble 12 can be guided so as to be accurately abutted against the end portion of the rod-shaped material 10 near the center, thereby fixing the rod-shaped material 10 more stably.

In the present embodiment, the heating coil 13 is a high-frequency heating coil that heats both end portions of the rod-like material 10 to an annealing temperature. The high-frequency heating coil is suitable for the annealing process of the end of the rod-shaped material 10 because of its high heating temperature and high heating speed.

In the present embodiment, as shown in fig. 3, the heating coil 13 is fixed in a through hole of a plane perpendicular to the axial direction of the coil bracket 17.

The length, shape and fixing mode of the first thimble 11 and the second thimble 12 can be set according to practical situations. For example, in other embodiments, the lengths of first and second thimbles 11 and 12 may be the same; the cross-sectional shapes of the first ejector pin 11 and the second ejector pin 12 may be polygonal instead of circular; the cross section of each of the first ejector pin 11 and the second ejector pin 12 in the length direction may be the same.

Those skilled in the art may also choose whether to provide separate first and second needle holders 115, 121 depending on the particular situation. For example, in other embodiments, both the cylinder and the slider 15 may be directly coupled to either the first needle 11 or the second needle 12.

The operation of the first thimble 11, the second thimble 12, and the heating coil 13 of the processing apparatus provided in the present embodiment will be described below:

under the operation of a worker or an automated machine, one end of the rod-shaped material 10 is brought into contact with the end of the first thimble 11, and then the second thimble 12 is moved in the direction (direction a) of the first thimble 11 along the guide rail 14 by the pushing of the cylinder, and is brought into contact with the other end of the rod-shaped material 10. At this time, the axis of the first thimble 11, the axis of the second thimble 12, the axis of the rod-like material 10, and the axis of the heating coil 13 are substantially collinear. Then, the first thimble 11 is moved in a direction (direction a) away from the second thimble by the pushing of the cylinder, and the second thimble 12 is moved in the same direction and at the same speed as the first thimble 11. The end of the rod-shaped material 10, which is in contact with the first thimble 11 sleeved with the heating coil 13, reaches the inside of the heating coil 13, and the first thimble 11 and the second thimble 12 are stopped moving, and at this time, the end of the rod-shaped material 10, which is in contact with the first thimble 11, is heated in the heating coil 13 for about 15 to 25 seconds. The first thimble 11 and the second thimble 12 continue to move in the same direction (direction a) as before, and in this process, the rod-shaped material 10 passes through the heating coil 13, and after the end portion of the rod-shaped material 10 abutting against the second thimble 12 reaches the inside of the heating coil 13, the first thimble 11 and the second thimble 12 again suspend moving, and at this time, the end portion of the rod-shaped material 10 abutting against the second thimble 12 is heated in the heating coil 13 for a time of about 15 to 25 seconds as well. After both ends of the rod-shaped material 10 are heated, the first ejector pin 11 and the second ejector pin 12 move together in the direction B, and the rod-shaped material 10 is returned to a predetermined position.

Referring to fig. 4, the processing apparatus in the present embodiment further includes: a feeding table 23 extending in parallel along the axial direction and being liftable; and a third thimble 21 and a fourth thimble 22 which are respectively arranged at two ends of the feeding table 23 and are coaxially arranged, and the fourth thimble 22 is arranged in a mode of being close to/far away from the third thimble 21.

By including the loading table 23 extending in the axial direction, the loading table 23 can carry the rod-like material 10 with a small space occupation. Because the rod-shaped material feeding device comprises the third thimble 21 and the fourth thimble 22 which are coaxially arranged, and the fourth thimble 22 can be close to or far from the third thimble 21, when the fourth thimble 22 is close to the third thimble 21, the third thimble 21 and the fourth thimble 22 can respectively abut against two end parts of the rod-shaped material 10 arranged on the feeding table 23, so that the rod-shaped material 10 is fixed at a specified position through the third thimble 21 and the fourth thimble 22, and the rod-shaped material 10 can be positioned and grabbed under the condition of automatic control. Since the loading table 23 is liftable, when the rod-shaped material 10 is fixed by the third ejector pins 21 and the fourth ejector pins 22, by lowering the loading table 23, it is advantageous to hold the rod-shaped material 10 relatively stably in the direction perpendicular to the axis of the rod-shaped material 10 under automatic control.

The loading table 23 may be lowered by a linear motion, a rotational motion, or the like to separate the loading table 23 from the rod-like material 10 originally mounted thereon.

In this embodiment, the third thimble 21 and the fourth thimble 22 are both disposed at the outer end of the loading table 23, and the farthest distance between the third thimble 21 and the fourth thimble 22 is greater than the length of the loading table 23. In other embodiments, the third ejector pin 21 and the fourth ejector pin 22 are disposed at the inner ends of the loading platform 23, and the furthest distance between the third ejector pin 21 and the fourth ejector pin 22 may be smaller than the length of the loading platform 23.

In this embodiment, the surface of the loading table 23 and/or the surface on which the rod-shaped material 10 is placed is provided with V-grooves, so that the rod-shaped material 10 is not likely to roll when being placed on the loading table 23, and the operation process of the processing equipment is more controllable.

In the present embodiment, the lower surface of the fourth thimble 22 is V-shaped and matches the shape of the loading table 23, so that when the length of the rod-shaped material 10 is short, the fourth thimble 22 can slide in the V-shaped groove of the loading table and contact with one end of the rod-shaped material 10.

The length of the feeding table 23 and the shape of the surface thereof, and the shapes of the third thimble 21 and the fourth thimble 22 can be set according to practical situations.

Referring to fig. 5 and 6, the present embodiment further includes: the transporting gripper 60 is movable between a region (M) where the third ejector pin 21 and the fourth ejector pin 22 are located and a region (N) where the first ejector pin 11 and the second ejector pin 12 are located, and the transporting gripper 60 includes a carrier block 61 and a presser block 62 which are disposed opposite to each other in a direction perpendicular to the axial direction.

Since the carrying grip 60 has the carrier block 61 and the presser block 62 oppositely disposed in the direction perpendicular to the axis, it is possible to achieve more stable gripping of the rod-like material 10 in the direction perpendicular to the axis of the rod-like material 10, thereby ensuring that the rod-like material 10 is not easily dropped during the travel of the carrying grip 60 from the region (M) where the third ejector pin 21 and the fourth ejector pin 22 are located to the region (N) where the first ejector pin 11 and the second ejector pin 12 are located.

The region (M) where the third ejector pin 21 and the fourth ejector pin 22 are located is a region where the carrier block 61 and the presser block 62 of the conveyance gripping clamp 60 can grip the rod-like material 10 originally located on the loading table 23 from between the third ejector pin 21 and the fourth ejector pin 22. The region (N) where the first ejector pin 11 and the second ejector pin 12 are located is a region where the conveyance grip 60 can bring the rod-shaped material 10 located between the carrier block 61 and the presser block 62 into contact with the end portions of the first ejector pin 11 and the second ejector pin 12.

In the present embodiment, the surface of the carrier block 61 for placing the rod-like material 10 is provided with V-grooves. In this way, the rod-like material 10 is less likely to roll when it is mounted on the carrier block 61, thereby allowing for more controlled operation of the processing apparatus.

In the present embodiment, the traveling mechanism of the transport gripper 60 includes the first traveling rail 36 and the first link plate 33 connected to the first traveling rail 36, and the gear of the first drive motor 381 connected to the first link plate 33 is engaged with the rack on the first traveling rail 36 to move the first link plate 33 on the first traveling rail 36. The running gear further comprises a second connecting plate 34 connected perpendicularly to the first connecting plate 33, and a third connecting plate 35 arranged parallel to the second connecting plate 34. The gear of the second driving motor 382 connected to the second connection plate 34 is engaged with the rack gear of the rear side of the third connection plate 35 so that the third connection plate 35 and the second connection plate 34 can slide relatively. The running gear further comprises a first driving cylinder 391 located behind the first running rail 36, the first driving cylinder 391 being able to push the first running rail 36 such that the first running rail 36 moves on the second running rail 37.

The handling gripper 60 is disposed on the third connecting plate 35, the handling gripper 60 has a carrier block 61 and a presser block 62 disposed opposite to each other, and the presser block 62 is driven by a second driving cylinder 63 to move in the direction of the carrier block 61, so as to grasp the rod-like material 10.

In other embodiments, the movement of the presser 62 in the direction of the carrier block 61 is achieved so as to grasp the rod-shaped material 10, either by carrying a crank-slider mechanism or by controlling the transmission of a rack and pinion mechanism by means of a hydraulic/pneumatic cylinder.

In other embodiments, the handling gripper 60 is configured to travel in different areas, either by a gear crank mechanism with stops, a rocker slide mechanism, a crank link mechanism, a sprocket feed mechanism, or the like.

The following will describe the operation of the carrying grip 60 and the traveling mechanism of the processing apparatus provided in the present embodiment:

the rod-shaped material 10 is placed on the loading table 23 under the operation of a worker or an automated machine. The fourth ejector pin 22 is moved in the direction of the third ejector pin 21, and the fourth ejector pin 22 is brought into contact with one end portion of the rod-shaped material 10, and then continues to move in the direction of the third ejector pin 21 to push the rod-shaped material 10. The other end of the rod-shaped material 10 is abutted against the third ejector pin 21 by the pushing of the fourth ejector pin 22. At this time, the third ejector pin 21 and the fourth ejector pin 22 are respectively abutted against both end portions of the rod-shaped material 10 to fix the rod-shaped material 10 between the third ejector pin 21 and the fourth ejector pin 22. The conveyance grip 60 is moved to a position intermediate the third ejector 21 and the fourth ejector 22. The presser block 62 is pressed down, and the conveyance gripper 60 grips the rod-like material 10 at an intermediate position. By the relative sliding of the second connecting plate 34 and the third connecting plate 35, the carrying gripper 60 moves upward, and after the rod-shaped material 10 is lifted up and moved along the first traveling rail 36 to a position opposite to the region between the first ejector pin 11 and the second ejector pin 12, the first driving cylinder 391 pushes the first traveling rail 36 to move forward along the second traveling rail 37, so that the carrying gripper 60 moves to the region between the first ejector pin 11 and the second ejector pin 12. By the relative sliding of the second link 34 and the third link 35 and the movement of the first link 33 on the first travel rail 36, one end of the rod-shaped material 10 gripped by the conveyance gripper 60 is brought into contact with the first ejector pin 11. Then, the second ejector pin 12 is moved in the direction of the first ejector pin 11 and is brought into contact with the other end of the rod-shaped material 10. At this time, the first thimble 11 and the second thimble 12 are respectively abutted against both end portions of the rod-shaped material 10 to fix the rod-shaped material 10 between the first thimble 11 and the second thimble 12. Then, the presser 62 is moved away from the carrier 61, and the transport gripper 60 releases the rod-like material 10 and returns to a predetermined position under the drive of the travelling mechanism.

Referring to fig. 7 and 8, the processing apparatus according to the present embodiment further includes: a receiving groove 41 provided in a form capable of extending and retracting to receive the rod-shaped material 10 dropped between the first ejector pin 11 and the second ejector pin 12; and a pusher block 42 sliding in the axial direction in the receiving slot 41. In this way, the heated rod-shaped material 10 can be easily transferred and stored.

The present embodiment further includes: a cooling tank 51; and a cooling basket 52 which is located in the cooling bath 51 and is liftable; and a transition plate 53 having a wide side abutting against the receiving groove 41, a long side abutting against the cooling basket 52, and the other long side hinged to the periphery of the cooling bath 51.

By including the cooling bath 51, the heated rod-like material 10 can be cooled by the cooling liquid in the cooling bath 51, thereby completing the entire heat treatment step (annealing step). Since the cooling basket 52 is provided in the cooling bath 51 and is vertically movable, the cooling basket 52 is lowered to allow the cooling basket 52 to be immersed in the cooling liquid in the cooling bath 51 together with the rod-shaped material 10 therein, and the cooled rod-shaped material 10 can be easily taken out by raising the cooling basket 52. Since the transition plate 53 is included, the wide side of the transition plate 53 is abutted with the receiving groove 41 so that the rod-shaped material 10 can be moved from the receiving groove 41 to the transition plate 53 under the pushing of the pushing block 42, and since one long side of the transition plate 53 is abutted with the cooling basket 52 and the other long side is hinged with the periphery of the cooling tank 51, when the rod-shaped material 10 is pushed onto the transition plate 53, the transition plate 53 rotates around the hinge shaft under the action of the gravity of the rod-shaped material 10 above the transition plate 53, the transition plate 53 forms a slope along which the rod-shaped material 10 falls into the cooling basket 52 and is immersed in the cooling liquid. Since the transition plate 53 forms a slope such that the side of the transition plate 53 that interfaces with the cooling basket 52 approaches the surface of the cooling liquid, the cooling liquid is less likely to splash out when the rod-like material 10 falls into the cooling liquid.

In other embodiments, a mechanical gripper may be used to grasp the heated rod-shaped material 10 and place it in the cooling bath 51.

The following will describe the operation of the receiving chute 41, the pusher block 42, the transition plate 53, the cooling bath 51, and the cooling basket 52 of the processing apparatus provided in the present embodiment:

the receiving groove 41 fixed to the slide plate 43 is slid and protruded in the direction of the region (N) between the first ejector pin 11 and the second ejector pin 12. The second thimble 12 is moved away from the first thimble 11, and the rod-shaped material 10 originally fixed between the first thimble 11 and the second thimble 12 falls into the receiving groove 41. After the receiving chute 41 containing the rod-like material 10 is retracted, the pusher block 42 is caused to enter the inside of the receiving chute 41 from one end of the receiving chute 41 and slide therein to push the rod-like material 10 from the other end of the receiving chute 41 to the transition plate 53. The transition plate 53 is hinged to the periphery of the cooling bath 51 in a door-like manner. The transition plate 53 rotates under the influence of the gravity of the rod-shaped material 10 and forms a slope, by which the rod-shaped material 10 is thus rolled into the cooling basket 52 and immersed in the cooling liquid of the cooling bath 51 together with the cooling basket 52.

Referring to fig. 5 and 9, the processing apparatus in the present embodiment further includes: a feeding device, a roller 71 and a movable vice 72 which are sequentially arranged along the feeding direction; a cutting device having a fixed jaw 81 and a cutting tool 82 disposed opposite to the fixed jaw 81; the feeding jig 90 transfers the rod-like material 10 cut into a predetermined length to the feeding table 23.

Since the roller 71 and the movable jaw 72 are provided, the movable jaw 72 can clamp the rod-shaped material 10 and move in the feeding direction, and the rod-shaped material 10 placed on the roller 71 can be easily moved in the feeding direction by the movable jaw 72. Since the fixed jaw 81 and the cutting tool 82 provided opposite to the fixed jaw 81 are provided, the fixed jaw 81 can clamp and stabilize the rod-shaped material 10, so that the cutting tool 82 can smoothly cut the rod-shaped material 10, thereby being advantageous in improving the cutting accuracy. The feeding jig 90 for transferring the rod-like material 10 cut into a predetermined length to the feeding table 23 is provided, so that the preceding cutting step and the subsequent heat treatment step are joined together, and the preceding cutting step and the subsequent heat treatment step are fully automated.

The feeding jig 90 in the present embodiment is formed as a pair of jaws extending in the axial direction of the rod-like material 10 and parallel to each other for holding the rod-like material 10 from the side portions thereof.

In the present embodiment, the movable vice 72 is connected to a servo motor, in other words, the movable vice 72 is controlled by the servo motor, so that the accuracy of feeding can be improved, and the rod-shaped material 10 can be cut within a tolerance range.

In the present embodiment, the fixed jaw 81 and the cutting tool 82 are connected to a servo motor, in other words, the fixed jaw 81 and the cutting tool 82 are controlled by the servo motor, so that the cutting accuracy can be improved, and the finish and verticality of the cut end face can be ensured.
