Description

Technical Field

[0001] The present invention provides a blank ejecting and reversing mechanism, which relates to the technical field of metal forging, and particularly relates to a blank ejecting and reversing mechanism of a forging press and its usage method. Background Art

[0002] Metal forging is a forming process that uses the hammer head, anvil block, punch of a forging machine or applies pressure to a blank through a die to cause plastic deformation, so as to obtain workpieces with the required shape and size. Through forging, defects such as as-cast porosity in the metal smelting process can be eliminated, and the toughness of the metal can be improved.

[0003] In existing forging production, manual operation of fixtures is usually combined with forging. The fixture operates the blank to extend into the forging range for partial forging, and manual operation of the fixture is combined with the forging press to move and flip the blank. However, in small-scale forging, the operation steps for metal blanks hardly change, and the manual operation can be completely replaced by an automatically controlled blank ejecting and reversing mechanism, which can not only save labor costs, but also unify production specifications and improve production capacity.

[0004] Therefore, those skilled in the art have proposed a blank ejecting and reversing mechanism of a forging press and its usage method, and designed a blank ejecting and reversing mechanism for supporting small forging equipment, which can facilitate the rapid forging production of downward workpieces. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a blank ejecting and reversing mechanism of a forging press and its usage method. The blank ejecting and reversing mechanism designed for supporting a small forging press can perform a blank ejecting and reversing operation at a specified angle on the workpiece during the forging process, and can complete the processes of clamping, lifting, flipping and resetting the workpiece within a complete cycle. In the forging production of small workpieces, the labor intensity of manual work can be significantly reduced, and mechanization can replace manual work for repetitive actions, ensuring processing accuracy and being beneficial to production.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A blank ejecting and reversing mechanism of a forging press includes a forging table, where blank forging is carried out within the range of the forging table, and a limiting structure is provided on the forging table to facilitate the limitation of the workpiece and prevent the forging workpiece from flying off.

[0007] In existing forging presses, the forging punch and the workpiece are manually controlled to cooperate with each other. Especially in the forging production of small workpieces, the worker picks up the workpiece with a tool, and flips the workpiece as the forging progresses to perform all-round forging processing of the workpiece. The progress of manual repetitive actions is slow, and there are operation differences that affect the accuracy. Therefore, it is proposed to replace manual work with mechanization to perform heavy repetitive work in forging production.

[0008] Installation columns are symmetrically and fixedly arranged on the outer side of the forging table, and multiple installation columns are symmetrically fixed on the outer side of the forging table.

[0009] Calipers are arranged on the side surfaces of the installation columns. Two symmetrically arranged calipers are synchronously driven by a power structure to move towards the middle to complete workpiece positioning, and the calipers arranged in different orientations are used for clamping operations of different workpieces.

[0010] The caliper includes a T-shaped clamping arm. The T-shaped clamping arm is inserted and arranged on the side surface of the installation column. The T-shaped clamping arms in the same group move forward synchronously to press against the surface of the workpiece, and then the workpiece is lifted and flipped along the installation column by the T-shaped clamping arm. The whole action process includes moving forward and pressing, lifting, flipping and resetting, and different transmission paths correspond to different processes.

[0011] Drive gears are arranged inside the installation column and the T-shaped clamping arm. The forward and backward, left and right movement and angular flipping of the T-shaped clamping arm relative to the installation column are all realized through the meshing transmission of different drive gears.

[0012] A first forward movement rod is slidably arranged on the side surface of the T-shaped clamping arm. The first forward movement rod moves forward together with the forward movement of the T-shaped clamping arm. When the T-shaped clamping arm moves near the workpiece, the first forward movement rod first contacts the surface of the workpiece. The first forward movement rod is extruded by the surface of the workpiece relative to the forward movement of the T-shaped clamping arm, and then the movement direction of the T-shaped clamping arm is changed through the first forward movement rod.

[0013] A first spring is tightly sleeved on the side surface of the first forward movement rod. During the reset process, the elastic force of the first spring helps the first forward movement rod to reset, and at the same time, it also ensures that the workpiece undergoes a settlement process opposite to the lifting.

[0014] Preferably, a first rotating shaft penetrates through and is connected to the side surface of the installation column through a bearing. The T-shaped clamping arm is meshed and connected to the first rotating shaft. With the driving of the first rotating shaft by the driving structure, the T-shaped clamping arm is driven to move forward accordingly through the meshing relationship.

[0015] A turntable is fixed at the end of the first rotating shaft. A pull rod is hingedly connected to the side surface of the turntable. One end of the pull rod far away from the turntable is hingedly connected to a control pedal. Different control pedals are manually controlled to control the forward movement of the calipers in different orientations. The driving of the turntable by the control pedal for one cycle completes the control of the whole positioning, lifting, flipping and sinking of the workpiece.

[0016] When the control pedal sinks, the turntable is pulled by the pull rod to rotate half a week, and at the same time, the first rotating shaft drives the T-shaped clamping arm to move forward along the horizontal direction through direct meshing.

[0017] Preferably, a fixed block is fixed on the side of the mounting column corresponding to the turntable, a first sliding groove is opened on the side of the fixed block, the pull rod passes through the first sliding groove and is slidably connected to the fixed block, and a second spring is provided on the side of the pull rod to press against the fixed block.

[0018] When the control pedal drives the pull rod to move, there is an angle change, so a first sliding groove is provided on the side of the fixed block, and the second spring is conveniently installed to reset the pull rod through the fixed block and the first sliding groove.

[0019] Preferably, a transmission track is provided on the inner side of the mounting column and is engaged with the first rotating shaft, and the first rotating shaft drives the T-shaped clamp arm to be lifted along the mounting column through the engagement of the transmission track.

[0020] A sleeve is penetrated and slidably arranged on the side of the mounting column, and the T-shaped clamp arm is slidably arranged on the inner side of the sleeve. On the one hand, the sleeve serves as a sliding mounting structure of the T-shaped clamp arm relative to the mounting column to provide an extension basis. On the other hand, the sleeve drives the T-shaped clamp arm to lift the workpiece along the mounting column.

[0021] Preferably, a second rotating shaft is passed through the side of the sleeve and the bearing is provided, and the T-shaped clamp arm is transmitted through the engagement of the second rotating shaft with the transmission track. In the step of positioning the workpiece, the rotational connection relationship between the second rotating shaft and the sleeve is not restricted, and it is an idling state at this time. The advancement of the first advancement rod limits the rotational connection relationship between the second rotating shaft and the sleeve. At this time, the transmission track and the second rotating shaft are in a clamping relationship, and the sleeve and the T-shaped clamp arm advance in the vertical direction together with the transmission track.

[0022] The side of the second rotating shaft is fixedly sleeved with a first ratchet, and the first advancing rod is arranged corresponding to the position of the first ratchet. When the T-shaped clamp arm approaches the workpiece, the first advancing rod contacts the workpiece in advance and is squeezed to advance. The advancing first advancing rod has a limiting relationship with the second rotating shaft fixed to the first ratchet, limiting the rotation of the second rotating shaft. At this time, the second rotating shaft will not drive the T-shaped clamp arm to advance horizontally with the advancement of the transmission track, and then the meshing relationship between the second rotating shaft and the transmission track is changed to a limiting relationship, and the second rotating shaft and the sleeve both advance in the vertical direction with the transmission track.

[0023] Preferably, a second slide groove is penetrated through the side surface of the carrying end of the T-shaped clamp arm, and claws are symmetrically arranged on the inner side of the second slide groove. The two claws symmetrically arranged at the carrying end of the T-shaped clamp arm can make a more stable and tight contact with the side wall of the workpiece.

[0024] The first advancing rod is inserted between two claws, and under the pressing action of a spring, the first advancing rod protrudes from the front end of the claws and contacts and presses against the side wall of the workpiece in front of the claws. As the T-shaped clamping arm continues to advance, the first advancing rod is pressed by the side wall of the workpiece and advances relative to the T-shaped clamping arm, and the relative advancement is used to control the switching of the movement direction of the T-shaped clamping arm.

[0025] Preferably, a reinforcing rod is hinged on one side of the two claws away from each other. The reinforcing rod forms an inclined supporting structure for the claws from one side of the claws to strengthen the strength of the claws.

[0026] A lead screw is slidably arranged inside the second chute. One lead screw is fixedly connected to the claw, and the other lead screw is slidably connected to the reinforcing rod. The lead screw extends to the side of the outer end of the second chute and is threadedly sleeved with a nut, and the installation angle of the claw and the reinforcing rod relative to the T-shaped clamping arm is adjusted through the nut.

[0027] Preferably, a dial rod is hinged inside the sleeve and on one side of the first ratchet wheel. The first ratchet wheel is limited by the deflection of the dial rod.

[0028] A second advancing rod is slidably arranged inside the sleeve corresponding to the dial rod. A wedge block is arranged at one end of the second advancing rod close to the dial rod. When the second advancing rod advances, the wedge block at the end pushes the dial rod to deflect to complete the limiting. A spring is also arranged on the side of the second advancing rod for resetting.

[0029] A convex block is fixedly connected to the side of the T-shaped clamping arm. The first advancing rod passes through the convex block and is slidably arranged parallel to the advancing direction of the T-shaped clamping arm. And a protruding structure for facilitating the pressing installation of the first spring is arranged on the side of the first advancing rod. The first spring is pressed against the side of the convex block, so that the first advancing rod can advance together with the T-shaped clamping arm and can also reset the T-shaped clamping arm and the first advancing rod through the first spring.

[0030] A second ratchet wheel is arranged on the side of the T-shaped clamping arm and at one end of the convex block close to the mounting column. The first advancing rod and the second advancing rod are respectively reversely meshed with the second ratchet wheel. When the first advancing rod advances with the T-shaped clamping arm, it will not drive the second advancing rod to advance. When the first advancing rod advances relative to the T-shaped clamping arm, the first advancing rod generates a reverse driving effect on the second advancing rod through the second ratchet wheel, and further drives the dial rod pressed by the end of the second advancing rod to press against the side of the first ratchet wheel to limit the rotation of the second rotating shaft.

[0031] Preferably, a driving gear is also fixedly sleeved on the side of the T-shaped clamping arm close to one end of the mounting column, and the rotation of the T-shaped clamping arm is driven by the driving gear.

[0032] Another advance end of the first advance rod is provided with a transmission gear. The first advance rod is inserted and arranged on the side of the sleeve along the vertical direction. After the T-shaped clamp arm rises to a certain height and encounters a preset obstacle, it advances. The transmission gear enters the meshing position with the transmission track, so that the transmission track can drive the T-shaped clamp arm to rotate.

[0033] It should be noted that the installation of the driving gear mentioned above on the side of the second rotating shaft and the T-shaped clamp arm is a resistance installation, that is, when encountering an obstacle or being subjected to resistance exceeding the resistance effect, the driving gear will overcome the fixed relationship and rotate, otherwise it will rotate with the second rotating shaft and the T-shaped clamp arm. This arrangement facilitates switching of the driving direction of the T-shaped clamp arm.

[0034] A method for using a forging machine top material reversing mechanism, the working process is as follows:

[0035] S1. Manually control the two symmetrically arranged T-shaped clamp arms to advance by synchronously controlling the control pedal to clamp and position the workpiece on the forging table. During the process, the control pedal pulls the first rotating shaft to rotate through the pull rod, and the first rotating shaft drives the second rotating shaft through the transmission track, and the second rotating shaft directly engages and drives the T-shaped clamp arms to advance along the horizontal direction;

[0036] S2, the first advancing rod arranged in parallel with the T-shaped clamp arm contacts the workpiece before the clamp claw, and as the T-shaped clamp arm continues to advance, the first advancing rod advances relative to the T-shaped clamp arm, and the advancement drives the second advancing rod through the second ratchet, and then drives the lever to rest on the side of the first ratchet to limit the rotation of the second rotating shaft, ending the horizontal advancement of the T-shaped clamp arm, and the second rotating shaft and the transmission track change from a rotational relationship to a clamping relationship, and the sleeve and the T-shaped clamp arm advance in the vertical direction along with the transmission track, and the workpiece lifting step is performed, so that the workpiece leaves the limit of the forging table for easy flipping;

[0037] S3, after the workpiece is lifted to a certain height, the workpiece is restricted in the vertical direction, a driving gear driving the T-shaped clamp arm to lift overcomes the resistance and is installed to idle, and at the same time, the first carry rod installed in the vertical direction contacts the obstacle and moves forward, and the transmission gear arranged at the end of the first carry rod moves between the transmission track and the driving gear on the side of the T-shaped clamp arm, and meshes with the transmission track under the pressing action of the driving gear on the side of the T-shaped clamp arm, and the T-shaped clamp arm flips at a set angle accordingly;

[0038] S4. After the workpiece is flipped by a specified angle, the first half of the movement cycle of the control pedal ends. Each structure of the ejector commutation mechanism resets successively under the action of the spring. First, the T-shaped clamping arm moves downward, and the first carry rod arranged vertically starts to reset. The transmission gear arranged at the end of the first carry rod disengages from the limit of the transmission track, and the workpiece stops flipping. Subsequently, the driving gear on the side of the second rotating shaft comes into play, and the T-shaped clamping arm continues to move downward along with the transmission track. After the workpiece falls onto the forging table, the T-shaped clamping arm starts to retract, and the pressing force of the first carry rod arranged parallel to the T-shaped clamping arm on the workpiece gradually decreases, and finally, a single ejector commutation operation on the workpiece ends.

[0039] The present invention discloses an ejector commutation mechanism of a forging press and its using method, and the beneficial effects thereof are as follows:

[0040] 1. The ejector commutation mechanism of the forging press and its using method are designed in cooperation with the problem of frequent repeated workpiece commutation requirements in small-scale forging production. The ejector commutation mechanism can complete the complete operations of positioning, lifting, commutation, and resetting of the workpiece in one operation cycle, realize the automatic commutation of the forging workpiece, and replace manual labor with mechanical structures for heavy and repetitive work, which not only reduces the labor intensity of workers but also improves the accuracy of forging production.

[0041] 2. The ejector commutation mechanism of the forging press and its using method are respectively provided with a first carry rod in the horizontal carry direction and the vertical carry direction of the caliper. After being squeezed, it makes a carry, restricts the original transmission path through the carry of the first carry rod, and then changes the movement direction of the caliper, and orderly switches and completes the positioning, lifting, and flipping of the workpiece at the specified position.

[0042] 3. The ejector commutation mechanism of the forging press and its using method are that the first carry rod arranged in the horizontal carry direction of the T-shaped clamping arm is tightly installed with the T-shaped clamping arm through a spring, so that the first carry rod moves together with the horizontal carry of the T-shaped clamping arm. The second ratchet fixed to the T-shaped clamping arm will not rotate when the first carry rod does not move relative to the T-shaped clamping arm. After the first carry rod contacts the side wall of the workpiece, it makes a carry relative to the T-shaped clamping arm, drives the second ratchet to rotate, and then drives the second carry rod unidirectionally through the second ratchet, and further pushes the shift lever to limit the first ratchet, so that the second rotating shaft switches from the state of meshing connection with the transmission track to the state of limit clamping connection. Not only does the entire T-shaped clamping arm make a vertical carry along with the rotation of the first rotating shaft, but also the limit of the second rotating shaft stops the horizontal carry of the T-shaped clamping arm.

[0043] 4. The ejector commutation mechanism of the forging press and its usage method. Symmetrical claw structures are slidably arranged at the advancing end of the T-shaped clamping arm to avoid the problem of unstable single-point positioning of the workpiece. In addition, a reinforcing rod of the support structure is hinged on the side of the claw, which can not only strengthen the structural strength of the claw, but also exert a thrust on the claw, so that after the claw abuts against the surface of the workpiece, deformation occurs to generate a continuous elastic force, realizing a more stable positioning effect.

[0054] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative efforts shall fall within the protection scope of the present invention.

[0055] The embodiments of the present invention disclose a blank ejecting and reversing mechanism of a forging press and its using method;

[0056] According to the attached Figure 1 As shown, it includes a forging table 1 for forging a blank within the range of the forging table 1. A limiting structure is provided on the forging table 1 to facilitate the positioning of the workpiece and prevent the forging workpiece from flying off. This device is used for the forging production of small workpieces. The forging table 1 is a device that can be easily obtained in the prior art, and the relevant structures and functions will not be described herein.

[0057] In the prior art, the forging presses are all manually controlled to make the forging punch and the workpiece cooperate with each other. Especially in the forging production of small workpieces, the worker uses tools to clamp the workpiece, and as the forging progresses, the workpiece is flipped to perform all-round forging processing of the workpiece. The manual repetitive actions progress slowly, and there are operation differences that affect the accuracy. Therefore, it is proposed to replace manual labor with mechanization to perform the heavy repetitive work in forging production.

[0058] Mounting columns 2 are symmetrically fixed on the outer side of the forging table 1, and a plurality of mounting columns 2 are symmetrically fixed on the outer side of the forging table 1.

[0059] Calipers 3 are arranged on the side surfaces of the mounting columns 2. The two symmetrically arranged calipers 3 are synchronously driven by a power structure to move towards the middle to complete the positioning of the workpiece. The calipers 3 are symmetrically mounted on the symmetrically arranged mounting columns 2 to clamp and position the workpiece from both sides of the workpiece. The calipers 3 arranged in different orientations are used for the clamping operations of different workpieces.

[0060] According to the attached Figure 4 and the attached Figure 5 As shown, the caliper 3 includes a T-shaped clamping arm 301. The T-shaped clamping arm 301 is inserted and arranged on the side surface of the mounting column 2. The T-shaped clamping arms 301 in the same group synchronously move forward to tightly press against the surface of the workpiece. The fixture involving the T-shaped structure can increase the positioning contact area with the workpiece and can be adjusted according to the use requirements.

[0061] The workpiece is then lifted and flipped along the mounting column 2 by means of the T-shaped clamp arm 301. The entire process includes advancing, tightening, lifting, flipping and resetting. Different processes correspond to different transmission paths. A step of lifting the workpiece is provided during the process to facilitate reversal of irregularly shaped workpieces after they leave the forging table 1.

[0062] A driving gear 302 is provided inside the mounting column 2 and the T-shaped clamp arm 301. The driving gear 302 does not refer to a single gear, but a matching structure of multiple mutually meshing kinetic energy transmission. The forward, backward, left, right, and angular flipping of the T-shaped clamp arm 301 relative to the mounting column 2 are all achieved through the meshing transmission of different driving gears 302. During the equipment operation cycle, the T-shaped clamp arm 301 moves to the specified position to trigger the limit of the previous transmission path and connect the next movement path.

[0063] A first advance rod 303 is slidably provided on the side of the T-shaped clamp arm 301. The first advance rod 303 advances together with the advance of the T-shaped clamp arm 301. When the T-shaped clamp arm 301 moves near the workpiece, the first advance rod 303 first contacts the surface of the workpiece. The first advance rod 303 is squeezed by the surface of the workpiece and advances relative to the T-shaped clamp arm 301, and then the movement direction of the T-shaped clamp arm 301 is changed by the first advance rod 303.

[0064] The side of the first carry rod 303 is tightly sleeved with the first spring 304. During the resetting process, the elastic force of the first spring 304 helps the first carry rod 303 to reset, while also ensuring that the workpiece undergoes a settlement process opposite to the lifting process. The rapid resetting of the first carry rod 303 can allow the equipment to exit the previous operating stage and avoid excessive movement caused by the meshing relationship.

[0065] According to the attached Figure 1 and attached Figure 2 As shown, the side of the mounting column 2 is penetrated by and connected to the first rotating shaft 4 through the bearing, and the T-shaped clamp arm 301 is meshingly connected to the first rotating shaft 4. The external power is transmitted to the movement of the caliper 3 through the first rotating shaft 4. As the driving structure drives the first rotating shaft 4, the T-shaped clamp arm 301 is correspondingly driven by the meshing relationship.

[0066] A turntable 5 is fixed to the end of the first rotating shaft 4, and a pull rod 6 is hingedly connected to the side of the turntable 5. The pull rod 6 is hinged to a non-axial position of the side of the turntable 5, so that the rotation of the turntable 5 can drive the pull rod 6 to perform telescopic movement.

[0067] One end of the pull rod 6 away from the turntable 5 is hinged with a control pedal 7. Manually control different control pedals 7 to perform the carry control of the calipers 3 in different directions. The control pedal 7 completes the control of the entire positioning, lifting, flipping and sinking of the workpiece during one cycle of driving the turntable 5. The control pedal 7 is a manually driven structure and can also be connected to an electronic control device. Through the periodic driving of the electronic control device, manual operation can be completely replaced. Here, the control pedal 7 is set only as a most common and easily available power input method.

[0068] When the control pedal 7 sinks, it pulls the turntable 5 to rotate half a week through the pull rod 6. At the same time, the first rotating shaft 4 drives the T-shaped clamping arm 301 to carry out in the horizontal direction through direct meshing with the T-shaped clamping arm 301, and after the T-shaped clamping arm 301 presses against the workpiece, the movement direction of the T-shaped clamping arm 301 is converted through the first carry rod 303, so that the T-shaped clamping arm 301 moves in the vertical direction. When the T-shaped clamping arm 301 reaches the limit in the vertical direction, the transmission path is switched again through another first carry rod to drive the T-shaped clamping arm 301 to rotate.

[0069] According to the attached Figure 3 As shown in the figure, a fixed block 8 is fixed to the side of the mounting column 2 corresponding to the turntable 5. A first chute 9 is opened on the side of the fixed block 8. The pull rod 6 passes through the first chute 9 and is slidably connected to the fixed block 8. A second spring 10 is sleeved on the side of the pull rod 6 against the fixed block 8.

[0070] When the control pedal 7 drives the pull rod 6 to move, there is an angular change. Therefore, the first chute 9 is opened on the side of the fixed block 8, and the second spring 10 can be conveniently reinstalled on the pull rod 6 through the fixed block 8 and the first chute 9.

[0071] A gasket is provided on the side of the pull rod 6 against the second spring 10, and the gasket slides along the first chute 9.

[0072] According to the attached Figure 4 As shown in the figure, a transmission track 11 is meshed with the first rotating shaft 4 on the inner side of the mounting column 2. The first rotating shaft 4 drives the T-shaped clamping arm 301 to lift along the mounting column 2 through the meshing of the transmission track 11, and drives it to carry out in the vertical direction in the state where the T-shaped clamping arm 301 is clamped with the transmission track 11.

[0073] A sleeve 12 is penetrated and slidably arranged on the side of the mounting column 2. The T-shaped clamping arm 301 is slidably arranged inside the sleeve 12. On the one hand, the sleeve 12 serves as a sliding mounting structure of the T-shaped clamping arm 301 relative to the mounting column 2, providing an extension foundation. On the other hand, the sleeve 12 drives the T-shaped clamping arm 301 to lift the workpiece along the mounting column 2, avoiding the instability problem existing in the multi-phase movement of a single structure.

[0074] According to the attached Figure 5As shown, the side of the sleeve 12 is penetrated and provided with a second rotating shaft 13 through bearings. The T-shaped clamping arm 301 is driven by the engagement of the second rotating shaft 13 with the transmission track 11. During the positioning step of the workpiece, the rotational connection relationship between the second rotating shaft 13 and the sleeve 12 is not restricted, and it is in an idling state at this time. The advancement of the first advancement rod 303 restricts the rotational connection relationship between the second rotating shaft 13 and the sleeve 12. At this time, the transmission track 11 and the second rotating shaft 13 are in a clamping connection relationship, and the sleeve 12 and the T-shaped clamping arm 301 advance vertically together with the transmission track 11.

[0075] A first ratchet wheel 14 is fixedly sleeved on the side of the second rotating shaft 13. The first advancement rod 303 is arranged corresponding to the position of the first ratchet wheel 14. When the T-shaped clamping arm 301 approaches the workpiece, the first advancement rod 303 comes into contact with the workpiece in advance and is squeezed to advance. The advanced first advancement rod 303 has a limiting relationship with the second rotating shaft 13 fixed to the first ratchet wheel 14, restricting the rotation of the second rotating shaft 13. At this time, the second rotating shaft 13 will not drive the T-shaped clamping arm 301 to advance horizontally with the advancement of the transmission track 11. Subsequently, the relationship between the second rotating shaft 13 and the transmission track 11 changes from an engagement relationship to a limiting relationship, and the second rotating shaft 13 and the sleeve 12 both advance vertically with the transmission track 11.

[0076] A second sliding groove 15 is penetrated and opened on the side of the advancing end of the T-shaped clamping arm 301. Claw jaws 16 are symmetrically arranged inside the second sliding groove 15. The two claw jaws 16 symmetrically arranged at the advancing end of the T-shaped clamping arm 301 can make more stable abutting contact with the side wall of the workpiece.

[0077] The first advancement rod 303 is inserted between the two claw jaws 16, and the first advancement rod 303 protrudes in front of the claw jaws 16 under the abutting action of the spring and contacts and abuts against the side wall of the workpiece in front of the claw jaws 16. As the T-shaped clamping arm 301 continues to advance, the first advancement rod 303 advances relative to the T-shaped clamping arm 301 under the abutting force of the side wall of the workpiece, and the movement direction of the T-shaped clamping arm 301 is switched through this relative advancement.

[0078] On the side where the two claw jaws 16 are away from each other, a reinforcing rod 17 is hinged. The reinforcing rod 17 forms an inclined support structure for the claw jaws 16 from one side, strengthening the strength of the claw jaws 16.

[0079] A lead screw 18 is slidably arranged inside the second sliding groove 15. One lead screw 18 is fixedly connected to the claw jaw 16, and the other lead screw 18 is slidably connected to the reinforcing rod 17. The lead screw 18 extends to the side of the outer end of the second sliding groove 15 and is threadedly sleeved with a nut, and the installation angle of the claw jaw 16 and the reinforcing rod 17 relative to the T-shaped clamping arm 301 is adjusted through the nut.

[0080] According to the appendix Figure 6 and the appendix Figure 7As shown, a shift lever 19 is hinged inside the sleeve 12 and on one side of the first ratchet 14, and the first ratchet 14 is limited by the deflection of the shift lever 19.

[0081] A second carry rod 20 is slidably arranged in the sleeve 12 corresponding to the shift lever 19. A wedge block is arranged at one end of the second carry rod 20 close to the shift lever 19. When the second carry rod 20 advances, the wedge block at the end pushes the shift lever 19 to deflect to complete the limitation. A spring is also arranged on the side of the second carry rod 20 for resetting.

[0082] A convex block 21 is fixedly connected to the side of the T-shaped clamping arm 301. The first carry rod 303 passes through the convex block 21 and is slidably arranged parallel to the advancing direction of the T-shaped clamping arm 301. And a protruding structure for conveniently mounting the first spring 304 to abut is arranged on the side of the first carry rod 303. The first spring 304 is abutted and arranged on the side of the convex block 21, so that the first carry rod 303 can advance together with the T-shaped clamping arm 301, and the T-shaped clamping arm 301 and the first carry rod 303 can be reset by the first spring 304.

[0083] A second ratchet 22 is arranged on the side of the T-shaped clamping arm 301 and at the end of the convex block 21 close to the mounting column 2. The first carry rod 303 and the second carry rod 20 are respectively arranged in reverse meshing with the second ratchet 22. When the first carry rod 303 advances along with the T-shaped clamping arm 301, it will not drive the second carry rod 20 to advance. When the first carry rod 303 advances relative to the T-shaped clamping arm 301, the first carry rod 303 generates a reverse driving effect on the second carry rod 20 through the second ratchet 22, and further drives the shift lever 19 abutted by the end of the second carry rod 20 to abut against the side of the first ratchet 14, restricting the rotation of the second rotating shaft 13.

[0084] A driving gear 302 is also fixedly sleeved on the side of the T-shaped clamping arm 301 close to the mounting column 2, and the rotation of the T-shaped clamping arm 301 is driven by the driving gear 302.

[0085] A transmission gear 23 is arranged at the advancing end of another first carry rod 303. The first carry rod 303 is inserted along the vertical direction on the side of the sleeve 12. When the T-shaped clamping arm 301 rises to a certain height and encounters a preset obstacle and advances, the transmission gear 23 enters the meshing position with the transmission track 11, so that the transmission track 11 can drive the T-shaped clamping arm 301 to rotate.

[0086] It should be noted that the above-mentioned driving gear 302 is installed on the side of the second rotating shaft 13 and the T-shaped clamping arm 301 with resistance. That is, when encountering an obstacle or a resistance exceeding the magnitude of the resistance, the driving gear 302 will overcome the fixed relationship and rotate. On the contrary, it will rotate together with the second rotating shaft 13 and the T-shaped clamping arm 301. Such a setting facilitates switching the driving direction of the T-shaped clamping arm 301.

[0087] According to the attached Figure 8 As shown, a fixed shaft is fixed at the end of the T-shaped clamping arm 301. A transmission shaft is also inserted and arranged at a position corresponding to the fixed shaft on the side of the sleeve 12. Transmission gears 23 are also fixedly sleeved on the sides of the fixed shaft and the transmission shaft.

[0088] When the T-shaped clamping arm 301 moves upward to a certain height and encounters an obstacle, the vertically arranged first carry rod 303 makes a carry relative to the sleeve 12. The transmission gears 23 arranged on the side of the carried first carry rod 303, the transmission gears 23 on the side of the fixed shaft, and the transmission gears 23 on the side of the transmission shaft are all in a free state. When the first carry rod 303 arranged vertically makes a carry relative to the sleeve 12, the transmission shaft is in an idling state. Through the transmission gears 23 on the side of the first carry rod 303 arranged vertically, the meshing transmission from the transmission track 11 to the fixed shaft can be realized, that is, the T-shaped clamping arm 301 is driven to rotate through the transmission track 11.

[0089] The transmission gear 23 does not only refer to a gear structure of a certain size or style. Helical gears, bevel gears, etc. of different specifications can be selected according to the transmission needs, as long as the transmission use is satisfied. Those skilled in the art can purchase and use them according to the use needs.

[0090] The usage process of the equipment is as follows:

[0091] S1. Manually control the two symmetrically arranged T-shaped clamping arms 301 to make a carry through the control pedal 7, clamp and position the workpiece on the forging table 1. During the process, the control pedal 7 drives the first rotating shaft 4 to rotate through the pull rod 6, and the first rotating shaft 4 drives the second rotating shaft 13 through the transmission track 11. The second rotating shaft 13 directly meshes to drive the T-shaped clamping arm 301 to make a carry along the horizontal direction.

[0092] S2. The first carry rod 303 arranged parallel to the T-shaped clamping arm 301 contacts the workpiece before the claw 16. As the T-shaped clamping arm 301 continues to make a carry, the first carry rod 303 makes a carry relative to the T-shaped clamping arm 301. This carry drives the second carry rod 20 through the second ratchet 22, and then drives the shift lever 19 to rest on the side of the first ratchet 14 to limit the rotation of the second rotating shaft 13, ending the horizontal carry of the T-shaped clamping arm 301. The second rotating shaft 13 and the transmission track 11 change from a rotating relationship to a clamping connection. The sleeve 12 and the T-shaped clamping arm 301 make a carry in the vertical direction along with the transmission track 11, performing the step of lifting the workpiece to make the workpiece leave the limit of the forging table 1 for convenient flipping.

[0093] S3. After the workpiece is lifted to a certain height, the advancement of the workpiece in the vertical direction is restricted. A driving gear 302 that drives the T-shaped clamping arm 301 to lift idles due to overcoming resistance during installation. At the same time, a first advancement rod 303 installed in the vertical direction contacts an obstacle and makes an advancement. The transmission gear 23 provided at the end of the first advancement rod 303 moves between the transmission track 11 and the driving gear 302 on the side of the T-shaped clamping arm 301 and meshes with the transmission track 11 under the pressing action of the driving gear 302 on the side of the T-shaped clamping arm 301, and the T-shaped clamping arm 301 then flips by a set angle.

[0094] S4. After the workpiece flips by a specified angle, the first half of the movement cycle of the control pedal 7 ends. Each structure of the ejector commutation mechanism resets successively under the action of the spring. First, the T-shaped clamping arm 301 moves downward, and the first advancement rod 303 arranged in the vertical direction starts to reset. The transmission gear 23 provided at the end of the first advancement rod 303 disengages from the limit of the transmission track 11, and the workpiece stops flipping. Then, the driving gear 302 on the side of the second rotating shaft 13 comes into play, and the T-shaped clamping arm 301 continues to move downward along with the transmission track 11. After the workpiece falls onto the forging table 1, the T-shaped clamping arm 301 starts to retract, and the pressing force of the first advancement rod 303 arranged parallel to the T-shaped clamping arm 301 on the workpiece gradually decreases, and finally, a complete operation of ejecting and commuting the workpiece once ends.

[0095] Usage effect of the equipment:

[0096] The ejector commutation mechanism of this forging press and its usage method are designed to meet the problem of frequent repeated workpiece commutation requirements in small-scale forging production. The ejector commutation mechanism can complete a complete operation of positioning, lifting, commuting, and resetting the workpiece in one operation cycle, realizing automatic commutation of the forging workpiece. It replaces manual labor with mechanical structures for heavy repetitive work, not only reducing the labor intensity of workers but also improving the accuracy of forging production.

[0097] Furthermore, first advancement rods 303 are respectively arranged in the horizontal advancement direction and the vertical advancement direction of the caliper 3. After being squeezed, they make an advancement, restricting the original transmission path through the advancement of the first advancement rods 303, thereby changing the movement direction of the caliper 3, and orderly switching and completing the positioning, lifting, and flipping of the workpiece at the specified position.

[0098] Furthermore, the first carry rod 303 arranged in the horizontal carry direction of the T-shaped clamping arm 301 is tightly installed with the T-shaped clamping arm 301 through the first spring 304, so that the first carry rod 303 moves together with the horizontal carry of the T-shaped clamping arm 301. The second ratchet wheel 22 fixed to the T-shaped clamping arm 301 will not rotate when the first carry rod 303 does not move relative to the T-shaped clamping arm 301. After the first carry rod 303 contacts the side wall of the workpiece, it makes a carry relative to the T-shaped clamping arm 301, driving the second ratchet wheel 22 to rotate, and then driving the second carry rod 20 unidirectionally through the second ratchet wheel 22, thereby pushing the shift lever 19 to limit the first ratchet wheel 14, so that the second rotating shaft 13 switches from the state of meshing connection with the transmission track 11 to the state of limit clamping connection. Not only does the entire T-shaped clamping arm 301 make a vertical carry as the first rotating shaft 4 rotates, but also the limit of the second rotating shaft 13 stops the horizontal carry of the T-shaped clamping arm 301.

[0099] Furthermore, symmetric claw 16 structures are slidably arranged at the carry end of the T-shaped clamping arm 301 to avoid the problem of unstable single-point positioning of the workpiece. In addition, a reinforcing rod 17 of the support structure is hinged on the side of the claw 16, which can not only strengthen the structural strength of the claw 16, but also exert a thrust on the claw 16, so that after the claw 16 abuts against the surface of the workpiece, it deforms to generate a continuous elastic force, realizing a more stable positioning effect.
