Description

Technical Field

[0001] The invention relates to a process for forging a crosspiece blank. Background Art

[0002] The anchor chain crosspiece is an indispensable component in anchor chain processing. In the process of using anchor chains on various ships and platforms, the crosspiece is an important component to increase and maintain the mechanical strength of the anchor chain.

[0003] At present, the processing of crossbar blanks into crossbars mainly includes three steps: loading, heating, and extrusion molding. The original equipment requires workers to manually operate each step, which has high labor costs, high labor intensity, and low efficiency. In addition, the temperature of the crossbar blank is high during the hot forging process, and workers are at risk of injury. After extrusion molding, there is a problem that the crossbar is adhered to the lower die of the forging and is difficult to remove. Summary of the invention

[0004] The technical problem to be solved by the present invention is generally to provide a fully automatic crossbar forging machine and method. The parent case is automatic crossbar forging machine and method CN202210020306.8, the application date of fully automatic crossbar forging machine and method is 20220110; the sub-case is the invention name: components and process of crossbar forging machine: 202311388979.X.

[0005] To solve the above problems, the technical solution adopted by the present invention is:

[0006] A crossbar billet forging process, performing the following steps;

[0007] S1, the material finishing machine stores the cross-piece blanks and outputs them one by one in a directional manner;

[0008] In S1, first, the material sorting machine stores the cross-bar blanks and outputs them one by one in a directional manner; then, when the movable plate frame moves to the upper dead center as the piston rod of the movable plate cylinder extends, the cross-bar blanks on the upper end surface of the movable plate roll to the upper end surface of the fixed plate behind the movable plate under the action of gravity and gradually rise; secondly, the cross-bar blanks on the upper supporting platform I roll onto the conveying chain of the material conveyor.

[0009] As a further improvement of the above technical solution:

[0010] The conveyor outputs the cross-gear blank axially; in S2, when the cross-gear blank reaches the input end of the V-shaped trough, the downward swing driving push rod drives the input end of the conveyor beam to swing downward, and the cross-gear blank slides in the V-shaped trough in the opposite direction and contacts with the rear stop positioning plate to achieve axial positioning; then, the V-shaped trough swings upward to reset; secondly, the adjustable positioning rod passes through the rear stop process slot hole and enters the V-shaped trough; thirdly, the adjustable positioning rod passes the cross-gear blank through the inner tapered hole of the conical claw sleeve and moves forward, and the outer wall of the cross-gear blank contacts with the side wall of the inner tapered hole, so that the three front elastic claw arms overcome the spring force of the reset retaining spring and open, and the three-point contact probe contacts with the outer wall of the cross-gear blank to detect whether there are defects on the outer wall of the cross-gear blank; then, the qualified products are fed into the induction heating furnace, and the unqualified ones are discharged by the robot.

[0011] The present invention solves the shortcomings of unstable manual feeding and potential safety hazards of manually operated equipment, and realizes automatic screening, automatic feeding, automatic heating of crossbar blanks, and then the robot grabs the crossbar blanks, feeds them into the forging machine, forges them, and takes out the crossbars. The entire process is fully automated, reducing production costs. The lower die seat of the forging machine is changed from the original fixed mode to an up and down movable form, which solves the problem that the crossbar of the original fixed die sticks to the die, causing the robot to be unable to take out the crossbar. The present invention has a reasonable design, low cost, durability, safety and reliability, simple operation, time and labor saving, money saving, compact structure and easy use.

DETAILED DESCRIPTION

[0025] like Figure 1-12The purpose of the present invention is to automatically complete the entire process from the crossbar blank (55) to the crossbar processing by various equipment, reduce the number of workers, and reduce the labor intensity of workers.

[0026] The invention comprises a material finishing machine (90), a material transporting machine (91), an induction heating furnace (31), a material receiving conveyor (33), a material feeding manipulator (41), a forging machine (92), and a material taking manipulator (93).

[0027] The material finishing machine (90) comprises a material finishing machine base (2), and finishing side plates (1) are arranged on both sides of the material finishing machine base (2); and a rolling plate (9) is inclined on the material finishing machine base (2).

[0028] A load-bearing swing arm (66) is provided between the rolling-in plate (9) and the finishing side plate (1), thereby driving the rolling-in plate (9) to swing;

[0029] The material finishing machine base (2) is covered with a base cover plate, a movable plate oil cylinder seat fixing plate is mounted on the base cover plate, a movable plate oil cylinder seat (3) is mounted on the movable plate oil cylinder seat fixing plate, and a movable plate pushing oil cylinder (4) is mounted on the movable plate oil cylinder seat (3);

[0030] The movable plate oil cylinder seat (3) is hinged to the movable plate pushing oil cylinder (4) by a pin shaft, a movable plate oil cylinder pulling ear (5) is installed on the upper end of the movable plate pushing oil cylinder (4), the movable plate oil cylinder pulling ear (5) is hinged to the movable plate ear seat (53) by a pin shaft, and a movable plate frame (6) is installed on the movable plate ear seat (53);

[0031] The movable plate frame (6) comprises an upper movable plate I (58), a middle movable plate II (61) and a lower movable plate III (63) connected to the movable plate ear seat (53). The reciprocating motion of the movable plate pushing the oil cylinder (4) drives the three upper movable plates I (58), the middle movable plate II (61) and the lower movable plate III (63) to move up and down at a certain tilt angle. The movable plate fixing frames (54) on the left and right sides are fixed with gears (7) at the back, and the gears (7) are meshed with two gears (8) on the same shaft; the back of each movable plate frame is equipped with a corresponding fixed plate, namely, an upper fixed plate I (57), a middle fixed plate II (59) and a lower fixed plate III (62); the upper movable plate I (5 8) The tops of the middle moving plate II (61) and the lower moving plate III (63) correspond to the upper bearing platform I (60), the middle bearing platform II (64) and the lower bearing platform III (65) respectively; the moving plate frame is parallel to the fixed plate and maintains a certain angle with the vertical direction. When the moving plate frame moves to the upper dead point, the upper end surface of the moving plate frame is slightly higher than the upper end surface of the corresponding fixed plate. The three moving plate frames maintain a certain height difference and rise step by step, and the cross-piece blank (55) is gradually lifted to the highest fixed plate; then, the cross-piece blank (55) rolls over the upper end of the rolling plate (10) that is in highest contact with the upper fixed plate I (57), and rolls onto the conveying chain of the conveyor that continuously moves in a circular motion.

[0032] A rolling plate (10) is vertically and obliquely arranged above the upper fixed plate I (57), and the upper end surface of the upper fixed plate I (57) is higher than or flush with the inclined upper surface of the rolling plate (10);

[0033] An upper rotating rear stop roller (56) is arranged on the back side above the upper fixed plate I (57), and the back side of the upper bearing platform I (60) lifting the crossbar blank (55) is in rolling contact with the upper rotating rear stop roller (56);

[0034] When the lower fixed plate III (62) is located at the terminal end of the downward stroke, the lower bearing platform III (65) is lower than the lower end of the rolling plate (9) and corresponds to the lower bearing platform III (65);

[0035] The widths of the upper bearing platform I (60), the middle bearing platform II (64) and the lower bearing platform III (65) are greater than one and less than two times the outer diameter of the cross-piece blank (55); the three fixed plates and the three movable plate frames are arranged at intervals from each other, and the height difference between the three fixed plates is the same as the height difference between the three movable plate frames, so that when the movable plate frame moves to the upper dead center as the piston rod of the movable plate cylinder extends, the cross-piece blank (55) on the upper end surface of the movable plate will roll to the upper end surface of the fixed plate behind the movable plate under the action of gravity, and the cross-piece blank (55) on the uppermost movable plate frame will roll to the conveying chain of the material conveyor.

[0036] The material conveyor (91) comprises two height-adjustable bases A (11) and a height-adjustable base B (12), on which a material conveyor support leg A (13) and a material conveyor support leg B (14) are fixed respectively, and a material conveyor crossbeam (15) is connected to the upper ends of the material conveyor support leg A (13) and the material conveyor support leg B (14); a driven sprocket (16) and a driving sprocket (17) are respectively installed at both ends of the material conveyor crossbeam (15), which are connected by a conveying chain (18) and are used to transport the cross-piece blank (55). An axis passes through the middle of the driving wheel. In addition to the sprocket on the axis, there are bearings on both sides of the sprocket to enable the driving wheel shaft to rotate. A driving sprocket is also installed at one end of the axis. This driving sprocket is connected to the sprocket installed on the material transport motor (19) by a roller chain, so that the hydraulic motor drives the driving sprocket to roll; the driven sprocket is fixed to the chain tensioning seat with the driven sprocket shaft, and the tensioning bolt of the chain tensioning seat can be adjusted forward and backward along the direction of the crossbeam to achieve the purpose of adjusting the tightness of the conveying chain. The material transport motor (19) is installed on a motor adjustment base plate (20) that can adjust the height vertically, and the motor adjustment base plate (20) is fixed on the support leg A (13) of the material transport machine. There are side baffles (29) on the left and right sides of the conveying chain (18) to block the cross bar blank (55) and prevent the cross bar blank (55) from rolling down;

[0037] A baffle opening is provided at the front end of one side baffle (29) so that the cross-piece blank (55) output by the conveyor chain (18) can roll onto the output material plate (25). A cross baffle (28) located above the conveyor chain (18) is provided between the side baffles (29) on both sides, and a cross baffle (28) located above the conveyor chain (18) is provided between the two side baffles (29). The function of the baffle is to block the stacked cross-piece blanks (55), so that the cross-piece blanks (55) passing through the cross baffle are continuous along the direction of the conveyor chain and are not stacked. The cross baffle (28) forms a certain angle with the conveyor chain (18). The function of the baffle is to block the stacked cross-piece blanks (55), so that the cross-piece blanks (55) passing through the cross baffle are continuous along the direction of the conveyor chain and are not stacked.

[0038] A material pushing cylinder (22) is disposed transversely at the front end of the baffle opening, and the movement direction of the piston rod of the material pushing cylinder (22) is perpendicular to the conveying chain (18). The material pushing cylinder (22) is fixed to the front end of the conveyor beam (15). A material pushing plate (23) parallel to the movement direction of the conveying chain (18) is fixed to the free end of the piston rod of the conveyor beam (15), and a material blank front baffle (21) perpendicular to the movement direction of the conveying chain (18) is disposed on the side of the material pushing plate (23) close to the transverse baffle (28); a conveying alignment plate (27) perpendicular to the movement direction of the conveying chain (18) is disposed on the side of the material pushing plate (23) away from the transverse baffle (28);

[0039] The transmission alignment plate (27) is perpendicular to the push plate (23), and the transmission alignment plate (27) can be continuously adjusted forward and backward along the moving direction of the conveying chain (18); the transmission alignment plate (27) is away from the driving sprocket (17) and is at a right angle to the push plate (23); the blank front baffle (21) and the transmission alignment plate (27) are fixed on the push plate (23), and the push plate (23) reciprocates with the movement of the push cylinder (22). When the push cylinder (22) is fully retracted, the blank front baffle (21) will not block the crosspiece blank (55) on the conveying chain (18) When the piston rod of the push cylinder (22) is extended, the front baffle plate (21) of the blank material can block the movement of the cross-piece blank (55) on the conveying chain (18), and the push plate (23) pushes the cross-piece blank (55) to move perpendicularly to the conveying chain (18), so that the cross-piece blank (55) is separated from the conveying chain (18) and enters the V-shaped trough (24) on the conveyor, and an output plate (25) is connected between the V-shaped trough (24) and the baffle opening;

[0040] The baffles on both sides of the conveying chain terminate at the position of the blank front baffle (21). By adjusting the position of the conveying alignment plate (27) on the push plate (23), the front and rear end surfaces of the cross-piece blank (55) pushed by the push cylinder (22) are flush with the blank front baffle (21) each time the push cylinder (22) moves, and the blank front baffle (21) will not be blocked by the front end of the rear cross-piece blank (55) when the push plate (23) moves. The push cylinder (22) is pushed to the front dead point and then withdrawn, and at the same time, the piston rod of the furnace feeding cylinder (26) extends to push the cross-piece blank (55) in the V-shaped trough (24) to move in a direction parallel to the conveying chain (18). The furnace feeding cylinder (26) is fixed on the side of the conveyor beam (15) and is opposite to the push cylinder (22). An adjustable positioning rod (74) is fixed to the free end of the piston rod of the furnace feeding oil cylinder (26), so that the adjustable positioning rod (74) pushes the cross bar blank (55) in the V-shaped material groove (24) to move a distance that is the same as the length of the cross bar blank (55).

[0041] The output end side of the V-shaped trough (24) is hinged on the conveyor beam (15) and a downward swing driving push rod (30) is hinged on the input end for driving the input end of the conveyor beam (15) to swing downward or reset; a rear stop positioning plate (67) having a rear stop process slot hole (68) is arranged in the groove at the input end of the V-shaped trough (24);

[0042] The inner diameter of the rear stop process slot hole (68) is smaller than the outer diameter of the cross stop blank (55) and is used to pass an adjustable positioning rod (74), thereby achieving length direction positioning.

[0043] A shape detection station (69) is arranged in the groove of the V-shaped material groove (24), and a conical claw sleeve (70) with an inner conical hole for passing the crosspiece blank (55) is arranged in the shape detection station (69), three front elastic claw arms (71) are respectively arranged on the front end side walls of the conical claw sleeve (70), a three-point contact probe (73) is arranged on the front end inner side walls of the front elastic claw arms (71), and a reset spring (72) is arranged on the outer side walls of the three front elastic claw arms (71) for resetting the three front elastic claw arms (71).

[0044] When the crossbar blank (55) reaches the input end of the V-shaped trough (24), the downward swing driving push rod (30) drives the input end of the conveyor crossbeam (15) to swing downward, and the crossbar blank (55) slides in the V-shaped trough (24) in the opposite direction and contacts with the rear stop positioning plate (67) to achieve axial positioning; then, the V-shaped trough (24) swings upward to reset; secondly, the adjustable positioning rod (74) passes through the rear stop process slot hole (68) and enters the V-shaped trough (24); thirdly, the adjustable positioning rod (74) passes the crossbar blank (55) through the inner tapered hole of the conical claw sleeve (70) and moves forward, and the outer side wall of the crossbar blank (55) contacts the side wall of the inner tapered hole, so that the three front elastic claw arms (71) overcome the spring force of the reset clamp (72) and open, and after the three-point contact probe (73) contacts with the outer side wall of the crossbar blank (55), it is used to detect whether there is a defect on the outer side wall of the crossbar blank (55);

[0045] After the crosspiece blank (55) in the V-shaped trough (24) moves to the front end of the V-shaped trough (24), it enters the guide trough (75) of the induction heating furnace (31). The guide trough (75) is fixed on the heating furnace support (32) of the induction heating furnace (31). The height of the legs of the heating furnace support (32) is adjustable so that the height of the induction heating furnace (31) can be adapted to the height of the V-shaped trough (24).

[0047] One end of the material guide driving wheel (78) is connected to the motor roller chain. The crawler chain (80) in the groove of the material receiving conveyor (33) drives the crossbar blank (55) falling into the guide rail to move forward and move to the material receiving tray (34). The lower end of the material receiving tray (34) is fixed with a material receiving cylinder (36). The material receiving cylinder (36) retracts the piston rod when the crossbar blank (55) enters the material receiving tray (34). The material receiving tray (34) starts to drive the crossbar blank (55) to move as the piston rod of the material receiving cylinder (36) extends. There is a positioning adjustment rod (38) on the movement path of the crossbar blank (55). The positioning adjustment rod (38) is fixed on the material receiving lower base (37). The positioning adjustment rod (38) is used to ensure that one end face of each crossbar blank (55) on the material receiving tray (34) is in the same position, so that it is convenient for the feeding manipulator to grab the crossbar blank (55).

[0048] The feeding manipulator (41) adopts a four-axis joint robot, and the feeding manipulator base (42) of the feeding manipulator (41) is fixed on the ground between the receiving lower base (37) and the forging machine; the manipulator rotation movement, up and down movement, and horizontal linear movement of the feeding manipulator (41) are all controlled by the forward and reverse rotation of the corresponding servo motor; the clamping device of the feeding manipulator (41) adopts a finger cylinder (81). When the receiving tray (34) drags the cross bar blank (55) to the position of the positioning adjustment rod (38), the feeding manipulator (41) receives the signal to grab the cross bar blank (55) from the receiving tray (34), and accurately sends the cross bar blank (55) to the forging machine die through program control. A sensor component (39) is arranged on one side of the receiving tray (34) for recording data and collecting information.

The piston rods and rod cavities all point to the same center. A guide shaft connecting plate is installed at the front end of the piston rod. The connecting plate is used to fix the corresponding oil cylinder guide shafts. The oil cylinder guide shafts include a pair of vertical forging machine side oil cylinder guide shafts (45) and a pair of horizontal forging machine vertical oil cylinder guide shafts (46).

[0051] Corresponding guide shaft connecting plates (83) are respectively arranged at the ends of the two forging machine side oil cylinder guiding shafts (45) and the two forging machine vertical oil cylinder guiding shafts (46); a forging machine side die (49) is arranged on the end faces of the guide shaft connecting plates (83) of the two forging machine side oil cylinder guiding shafts (45), and the ends of the forging machine side die (49) are respectively used for pressure contact with the horizontal ends of the cross bar blank (55);

After the upper die (48) and the lower die (82) of the forging machine are pressed tightly, the side die (49) of the forging machine completes extrusion in the horizontal direction at the same time. After extrusion molding, the side die (49) of the forging machine does not move, the upper die (48) of the forging machine rises, and the lower die (82) of the forging machine quickly descends and resets. At the same time, the side die (49) of the forging machine withdraws, and the crossbar product is completed.

[0054] The material-retrieving robot (93) includes four front and rear adjustment seats fixed at the lower end of the support legs, and two groups of linear slider modules (84) are installed on the cross beam at the upper end of the support legs. The linear slider module (84) corresponds to the lifting cylinder fixing seat (85), and the lifting cylinder fixing seat (85) is provided with upper lifting fingers (86) and lower lifting fingers (87) facing each other up and down; the discharge cylinder (89) is placed horizontally and connected to the lifting cylinder fixing seat (85); the upper lifting fingers (86) and the lower lifting fingers (87) move up and down to clamp or release the cross bar blank (55), and the finger cylinder is pushed in and out of the forging machine under the action of the discharge cylinder (89).
