DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention will be further described below in conjunction with the embodiments.

[0029] Example: Cold heading machine front-pass mechanism, such as Figure 1-Figure 8As shown, it includes a main body 1 and a driving module 2 for pushing the casting, the driving module 2 is used to drive the front-through mechanism to push the workpiece out; and a sliding plate 3 which is rotatably connected to the main body 1 and has through holes evenly opened on the surface. By setting the sliding plate 3, it can play a role in receiving the workpiece and facilitate the workpiece to slide to the outside. Moreover, through holes are opened on the surface of the sliding plate 3, so that the cold forging oil on the surface of the workpiece can pass through it to the inside of the oil storage tank 4, thereby achieving the purpose of reuse.

[0030] The surface of the slide plate 3 is symmetrically inclined with guide grooves 301, which can play a guiding and limiting role; an oil storage tank 4 is arranged below the slide plate 3, and the oil storage tank 4 is used to store the cold heading oil adhered to the surface of the workpiece during the processing, so as to facilitate reuse;

[0031] Specifically, a first filter screen 401 is fixedly installed on the inner wall of the oil storage tank 4. By setting the first filter screen 401, large debris generated during the processing of the workpiece can be filtered for the first time; a second filter screen 402 is inserted below the first filter screen 401, and the filter hole diameter of the second filter screen 402 surface is smaller than the filter hole diameter of the first filter screen 401. By setting the second filter screen 402 and setting the filter hole specifications on the surface of the second filter screen 402 to be smaller than the filter hole specifications on the surface of the second filter screen 402, the cold heading oil passing through the first filter screen 401 can be filtered for the second time to remove finer debris in the cold heading oil, so that the cold heading oil entering the oil storage tank 4 is purer, avoiding the blockage of the oil pipeline, and at the same time, by inserting the second filter screen 402 below the first filter screen 401, when the second filter screen 402 needs to be taken out for cleaning and replacement, it can be removed and replaced;

[0032] See attached Figure 2 and attached Figure 3 By setting a pusher 5 and setting it inside the main body 1, the action of the driving module 2 can drive its movement, push the workpieces that fall on the slide plate 3, and avoid the accumulation of workpieces. This solves the existing problem that the pushed workpieces will accumulate on the surface of the slide plate 3, and manual cleaning is required, which increases the workload.

[0033] The pusher 5 includes a bending rod 501 fixedly connected to the lower end of the driving module 2. The bending rod 501 is in an L-shaped structure and is rotatably connected to the inner wall of the body 1 through a round rod. By setting the L-shaped bending rod 501, the hinged rod 502 can be driven to move by the action of the driving module 2; the lower end of the bending rod 501 is movably connected to the hinged rod 502, and the hinged rod 502 is provided to play a connecting role. One end of the hinged rod 502 is movably connected to a push plate 503 through a hinge seat, and the push plate 503 is slidably matched with the guide groove 301 through a sliding rod. By providing the push plate 503, the workpieces falling on the sliding plate 3 can be pushed to avoid accumulation.

[0034] Specifically, when the driving module 2 starts to push the workpiece out, it will drive the bending rod 501 to start rotating around the round rod, and then drive the hinged rod 502 hinged to the bending rod 501 to start moving. The moving hinged rod 502 starts to drive the push plate 503 to start shrinking toward the inside of the main body 1. After the driving module 2 pushes the workpiece out, the driving module 2 will start to reset. At this time, the push plate 503 hinged to the hinged rod 502 will start to extend along the guide groove 301 through the bending rod 501, and then the workpiece fallen on the sliding plate 3 will be pushed out, avoiding accumulation and reducing the workload of workers.

[0035] See attached Figure 4 -Attached Figure 6 By setting a vibration mechanism 6 and symmetrically setting it below the slide plate 3, and two sets of vibration mechanisms 6 are installed on the inner wall of the main body 1, the slide plate 3 can be intermittently vibrated following the movement of the pusher 5, and at the same time cooperate with the pusher 5 to avoid the problem that part of the workpiece sticks to the surface of the slide plate 3 and cannot be unloaded due to the excessive viscosity of the cold heading oil.

[0036] Specifically, the vibration mechanism 6 includes a turntable 601 rotatably connected to the inner wall of the main body 1, and a protrusion 602 is provided on the surface of the turntable 601. By providing the protrusion 602, the turntable 601 can rotate along with the rotation of the turntable 601, so as to achieve intermittent vibration of the sliding plate 3; a ratchet 603 is fixedly installed on one side of the turntable 601, and the ratchet 603 is meshed with a pawl 604. By setting the pawl 604, it can mesh with the ratchet 603, so as to drive the ratchet 603 to rotate.

[0037] Among them, a horizontal plate is set on the lower side of the pawl 604, and the end of the horizontal plate contacts the inner wall of the groove opened on the surface of the connecting rod 605. By setting the horizontal plate, the rotation direction of the pawl 604 can be restricted when it is in action, so that it can only rotate counterclockwise but not clockwise.

[0038] Moreover, the pawl 604 is installed in the groove provided on the surface of the connecting rod 605 through the reset member 6041. The reset member 6041 is a torsion spring sleeved on the rotating shaft surface of the pawl 604, and the reaction force generated by its deformation can reset the rotating pawl 604. One end of the connecting rod 605 is fixedly connected to the hinge rod 502. Through the fixed connection between the connecting rod 605 and the hinge rod 502, the connecting rod 605 can be driven to move through the action of the hinge rod 502, so that the vibration mechanism 6 can vibrate the sliding plate 3 and shake off the workpiece stuck on the sliding plate 3. A cleaning mechanism 7 is provided on one side of the connecting rod 605. By providing the cleaning mechanism 7, the surface debris of the first filter screen 401 installed inside the oil storage tank 4 can be cleaned to avoid blockage.

[0039] Specifically, when the hinged rod 502 moves, it will drive the connecting rod 605 to move synchronously. When the connecting rod 605 follows the hinged rod 502 to extend, it will drive the pawl 604 to push the ratchet 603 to start rotating. The rotation of the ratchet 603 will drive the turntable 601 to start rotating, and then drive the protrusion 602 opened on its surface to rotate synchronously. As the hinged rod 502 begins to shrink, the connecting rod 605 will drive the pawl 604 to shrink synchronously. During the shrinkage process, the surface of the pawl 604 will be squeezed with the surface of the ratchet 603, so that it starts to rotate counterclockwise and drives the torsion spring to start to deform and generate a reaction force, so that the pawl 604 can be reset. As the connecting rod 605 moves back and forth, it will drive the protrusion 602 to intermittently vibrate the slide plate 3 to ensure that the workpieces on the slide plate 3 will not accumulate.

[0040] See attached Figure 3 and attached Figure 7 , wherein the cleaning mechanism 7 includes a rack 701 provided on one side of the connecting rod 605, the rack 701 is meshedly connected with a half gear 702, and by setting the half gear 702, the rack 701 is rotated under the reciprocating movement; the half gear 702 is connected and fixed to the first gear 703 through a cylinder installed on the inner wall of the body 1, and by setting the first gear 703, it can rotate following the rotation of the half gear 702; the surface of the first gear 703 is meshedly connected with a second gear 704, and by setting the second gear 704, it can rotate synchronously with the first gear 703 in cooperation with the first gear 703 to realize power transmission.

[0041] The second gear 704 is sleeved on the outer surface of the bidirectional screw rod 705 which is rotatably connected to the inner wall of the oil storage tank 4. By setting the bidirectional screw rod 705, it is possible to drive the parts to reciprocate. The bidirectional screw rod 705 is meshingly connected with a movable plate 706, which is arranged inside the oil storage tank 4, and the movable plate 706 is slidably matched with the sliding groove provided on the inner wall of the oil storage tank 4 through a slider fixedly installed at its end. By setting the movable plate 706, on the one hand, it can reciprocate following the rotation of the bidirectional screw rod 705, and on the other hand, it can drive the parts installed at its lower end to move synchronously.

[0042] Brushes 707 are symmetrically installed on the lower surface of the movable plate 706. The brushes 707 are arranged above the first filter 401, and the lower ends of the brushes 707 are in contact with the upper surface of the first filter 401. By arranging the brushes 707, debris on the surface of the first filter 401 can be cleaned to prevent the filter holes on the surface of the first filter 401 from being blocked. A clearing piece is arranged between the two groups of brushes 707. By arranging the clearing piece, debris stuck inside the filter holes on the surface of the first filter 401 can be cleaned.

[0043] Specifically, when the connecting rod 605 moves back and forth, the rack 701 will drive the first gear 703 to rotate synchronously through the meshing half gear 702. The rotation of the first gear 703 will drive the meshing second gear 704 to rotate synchronously. The rotation of the second gear 704 will drive the bidirectional screw rod 705 plugged in it to rotate synchronously, and then drive the moving plate 706 that slides with the inner wall of the oil storage tank 4 to start reciprocating movement, thereby driving the brush 707 to start cleaning the debris on the surface of the first filter screen 401 to avoid clogging of the filter holes and affecting the filtering effect.

[0044] See attached Figure 8 The dredging component includes a mounting plate 8, which is formed by splicing two groups of identical shells together. By setting the mounting plate 8, it is convenient to install the dredging component to achieve the function of dredging the filter holes of the first filter screen 401.

[0045] The lower surface of the mounting plate 8 is provided with a plurality of mounting grooves at equal intervals, and the mounting grooves are provided to facilitate installation of components for unclogging the filter holes of the first filter screen 401; a unclogging rod 801 is provided inside the mounting groove, and the lower end of the unclogging rod 801 is a spherical structure, and the diameter of the unclogging rod 801 is slightly smaller than the filter holes provided on the surface of the first filter screen 401; by providing the unclogging rod 801, and the diameter of the unclogging rod 801 is slightly smaller than the diameter of the filter holes, the unclogging rod 801 can enter the interior of the filter holes, push out the debris stuck inside the filter holes and drop it onto the surface of the second filter screen 402; the upper surface of the unclogging rod 801 is connected and fixed to the inner wall of the mounting groove by a spring 802, and by providing the spring 802, the unclogging rod 801 can be pushed to move by the reaction force generated by its squeezing.

[0046] Specifically, in the process of the movable plate 706 following the reciprocating movement of the bidirectional screw rod 705, the brush 707 installed on its lower surface and the mounting plate 8 will move synchronously, and the brush 707 will clean the debris on the surface of the first filter screen 401, and the clearing rod 801 installed inside the mounting plate 8 will enter each filter hole opened on the surface of the first filter screen 401 during the movement of the movable plate 706, and the clearing rod 801 with a spherical structure at the end will push out the debris stuck in the filter hole of the first filter screen 401 and drop it onto the surface of the second filter screen 402, ensuring that the first filter screen 401 will not be blocked. When there is too much debris on the surface of the second filter screen 402 and its filtering effect is affected, the handle on the surface of the second filter screen 402 (not shown in the figure) can be directly pulled to pull it out for cleaning and replacement.
