Description

Technical Field

[0001] The invention relates to the field of liquid agricultural production equipment, in particular to a self-propelled mold clamp control system. Background Art

[0002] With the increasing requirements for the diversification of enterprise product types and the complexity of styles, a variety of molds with different tables and tonnages are needed on mechanical presses to cooperate with production. The higher the frequency of mold replacement, the longer the mold change time will be, and it often takes a lot of manpower and time. Not only does it increase production costs, but it also reduces output efficiency. After the mold is replaced, it is fixed to the machine tool slide. It not only needs to be locked to prevent it from falling off, but also needs to be disassembled and loosened after the mold is used to cooperate with the replacement of the next mold. In order to save automation costs, some companies rely entirely on manual bolt locking for this mold locking process, which consumes a lot of manpower and is slow to lock. Work-related accidents of mold change workers are inevitable, which also increases the production costs of enterprises. Moreover, manual operation cannot quickly replace larger molds, which limits the development of enterprises.

[0003] In order to significantly shorten the mold change time, improve production safety and efficiency, and realize the automation of mold change, some companies have already used the rapid mold change system. The rapid mold change system requires the automation of mold locking and mold removal, that is, the self-propelled mold clamp is produced. The self-propelled mold clamp is installed in front and behind the slider and requires gas-liquid linkage control. Some self-propelled mold clamp control systems connect all the oil inlets of the automatic mold clamps in series and are controlled by a solenoid valve. If the solenoid valve fails, the mold will be in danger of loosening and safety is not guaranteed. There are also self-propelled mold clamp control systems that do not have a throttle valve installed, so the walking speed of the automatic mold clamp cannot be adjusted, and the degree of automation is not high.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] The oil inlet circuit assembly includes an air-controlled gear oil pump 17, a one-way valve 20, a one-way valve 16, a stop valve 15, and an oil suction filter 21. The oil inlet control assembly 2 600 has the same structure as the oil inlet control assembly 1 500. The oil inlet control assembly 1 600 includes a two-position four-way solenoid valve 14, a two-position two-way solenoid valve 13, and a pressure switch 12. The structures of the self-propelled model assembly 1 100, the self-propelled model assembly 200, the self-propelled model assembly 3 300, and the self-propelled model assembly 4 400 are all the same. The self-propelled model assembly 200 includes a self-propelled model body, a three-position four-way solenoid valve 1, a speed control valve 1 2, and a speed control valve 2 7. The three-position four-way solenoid valve 1 is equipped with a muffler. The self-propelled model body includes a gear plate 3, a chain 4, a cylinder 6, a T-slot track 8, a detection seat 10, a proximity switch 11, and a clamping head 9.

[0022] The pressure reducing valve 19 is connected to the main air source 700 through the air filter 18, and the oil inlet circuit assembly, the oil inlet control assembly 500, and the oil inlet control assembly 600 are respectively connected to the pressure reducing valve 19, wherein the air-controlled gear oil pump 17 is connected to the pressure reducing valve 19, the oil inlet of the air-controlled gear oil pump 17 is connected to the one-way valve 20, the one-way valve 20 is connected to the oil tank through the oil suction filter 21, the oil outlet of the air-controlled gear oil pump 17 is connected to the one-way valve 16, the one-way valve 16 is connected to the stop valve 15, and the oil inlet control assembly 500 and the oil inlet control assembly 600 are respectively connected to the stop valve 15. Taking the oil inlet control component 500 as an example, the air inlet of the two-position four-way solenoid valve 14 is connected to the pressure reducing valve 19, the air outlet of the two-position four-way solenoid valve 14 is connected to the two-position two-way solenoid valve 13, the inlet of the two-position two-way solenoid valve 13 is connected to the stop valve 15 of the oil inlet circuit component, and the outlet is connected to the pressure switch 12, the oil return circuit of the two-position two-way solenoid valve 13 is connected to the oil tank 900, the self-propelled model component 100 and the self-propelled model component 400 are respectively connected to the pressure switch 12, and the two-position four-way solenoid valve 14 is connected to the PLC signal.

[0023] The main air source enters along the air filter and the pressure reducing valve, and then is divided into two branches. One enters the right side of the air-controlled gear oil pump, and the other goes along branch C and then divides into branches C1 and C2. C1 and C2 are respectively connected to the air inlets of two two-position four-way solenoid valves.

[0024] The hydraulic oil is connected from the oil tank to the oil inlet of the air-controlled gear pump through the oil suction filter and the one-way valve. Then the hydraulic oil comes out from the left side of the air-controlled gear pump, connects the one-way valve and the stop valve in sequence, and then is divided into two branches A1 and A2. A1 and A2 are respectively connected to the inlets of two two-position two-way solenoid valves. One end of branches B1 and B2 is respectively connected to the inlets of two two-position two-way solenoid valves, and the other end is merged into branch B and returned to the oil tank. The hydraulic oil comes out of the two two-position two-way solenoid valves, respectively connected to the pressure switch, and passes through branch D and branch E. The hydraulic oil in branch D is divided into two routes: one route goes along the oil inlet branch three to the oil inlet of self-propelled model component three 300, and the other route goes along the oil inlet branch two to the oil inlet of self-propelled model component two 200. The hydraulic oil in branch E is also divided into two paths: one path goes along the oil inlet branch one to enter the oil inlet port of self-propelled model component one 100, and the other path goes along the oil inlet branch four to enter the oil inlet port of self-propelled model component four 400.

[0025] Taking the self-propelled model assembly 200 as an example, the inlet of the three-position four-way solenoid valve 1 is connected to the main air source 2 800, and the two air outlets of the three-position four-way solenoid valve 1 are respectively connected to the speed control valve 1 2 and the speed control valve 2 7, the cylinder 6 is arranged above the T-slot track 8, and the two are respectively connected to the press slider, the gear plate 3 is connected to the piston 5 of the cylinder 6, the clamping head 9 is slidably connected to the T-slot track 8, the chain 4 is wound on the gear plate 3, one end of the chain 4 is fixed to the cylinder 6, and the other end is connected to the connecting clamping head 9, the detection seat 10 is fixed to the T-slot track 8 by bolts, the proximity switch 11 is installed on the detection seat 10, the proximity switch 11 is connected to the PLC signal, the clamping head 9 is connected to the oil inlet branch 2, the speed control valve 1 2 and the speed control valve 2 7 are respectively connected to the cylinder 6, and the three-position four-way solenoid valve 1 is connected to the PLC signal.

[0026] In the self-propelled mold assembly 2, the gear plate, chain, piston, and clamping head can move, the clamping head is an existing hydraulic clamp, and the cylinder and T-slot track are fixed. The chain is extended and retracted through the piston on the cylinder, driving the clamping head to move on the T-slot track.

[0027] The compressed air source of the main air source 2 enters the air source branch 1, air source branch 2, air source branch 3, and air source branch 4 respectively, that is, the four branches leading to the self-propelled model component 1, self-propelled model component 2, self-propelled model component 3, and self-propelled model component 4. The compressed air source is connected to the inlet of the three-position four-way solenoid valve through the air source branch 2. One outlet of the three-position four-way solenoid valve is connected to the speed control valve 1 to enter the air inlet 2 of the cylinder, and the other outlet is connected to the speed control valve 2 to enter the air inlet 1 of the cylinder. The connection method of the other three air source branches 1, air source branch 3, and air source branch 4 is the same as that of air source branch 2. The four three-position four-way solenoid valves on these four air source branches are all connected to the PLC.

[0028] When the machine tool is ready to start working, manually open all the stop valves and keep them in the normally open state. The air-controlled gear oil pump needs to be opened by air control, so it is controlled by the main air source. When the main air source is inhaled, the air source enters the air-controlled gear oil pump, and the air-controlled gear oil pump starts to work and suck in hydraulic oil.

[0029] When the mold on the slider only needs to be clamped or loosened in place, the signal is transmitted to the PLC. After receiving the command, the PLC controls the three-position four-way solenoid valve on the air source branch 1 to the air source branch 4 to be in the middle position, and the air inlet 1 and the air inlet 2 of the self-propelled mold component 1 to the self-propelled mold component 4 are not intake, so the clamping heads on the self-propelled mold component 1 to the self-propelled mold component 4 are in place.

[0030] When the mold needs to be clamped in place, the signal is transmitted to the PLC, and the PLC controls the two-position four-way solenoid valves on branches C1 and C2 to be in the left position without air intake. Because the two-position two-way solenoid valves at the front of branches D and E are controlled by the two-position four-way solenoid valves of branches C1 and C2 respectively, the two-position two-way solenoid valves are immobile and in the right position. Then branch A1 is connected to branch D, and branch A2 is connected to branch E. The hydraulic oil enters the oil inlet of self-propelled mold assembly 1 to self-propelled mold assembly 4 respectively. The hydraulic oil pressure P acts on the piston surface S of the clamping head, and the generated force F=P×S overcomes the spring force in the clamping head and pushes the clamping head upward to realize the mold clamping function. On the contrary, when the mold needs to be relaxed in situ, the signal is transmitted to the PLC, and the PLC controls the two-position four-way valves on branches C1 and C2 to be in the right position for air intake, and then controls the two-position two-way solenoid valves at the front end of branches D and E to move to the left position. At this time, branch B1 is connected to branch D, and branch B2 is connected to branch E. Then, the hydraulic oil in the clamping heads of self-propelled mold assembly 1 to self-propelled mold assembly 4 returns to the oil tank under the action of the clamping head spring force, and the spring force pushes the clamping head to move downward, thereby realizing the mold relaxation function.

[0031] When a larger mold is replaced on the slider and needs to be clamped or loosened, the signal is transmitted to the PLC. After receiving the instruction, the PLC first controls the two-position four-way solenoid valve on branches C1 and C2 to move to the right position for ventilation, and then pushes the two-position two-way solenoid valve on branches D and E to move to the left position. At this time, the clamping head on the self-propelled mold assembly 1 to the self-propelled mold assembly 4 moves downward under the action of the spring force and is in a relaxed state; the second step is to control the three-position four-way solenoid valve on the air source branch 1 to the air source branch 4 to move to the upper position for ventilation, and then the air source enters the air inlet 2 of the self-propelled mold assembly 1 to the self-propelled mold assembly 4 along the speed control valve 1, pushing the piston downward. Then drive the gear plate and chain to move downward. The chain pushes the clamping head along the T-slot guide rail from the F position to the G position. After the clamping head reaches the G position, the proximity switch is powered off. The proximity switch transmits the signal that the clamping head has moved to the G position to the PLC. Then the PLC controls the three-position four-way solenoid valve to return to the middle position, ensuring that the clamping head is always stationary at the G position. When the mold needs to be clamped, the signal is transmitted to the PLC, and the PLC controls the two-position four-way on branches C1 and C2 to be in the left position without air intake. Because the two-position two-way solenoid valves at the front end of branches D and E are controlled by the two-position four-way solenoid valves of branches C1 and C2 respectively, the two-position two-way solenoid valves are stationary in the right position. Then branch A1 is connected to branch D, and branch A2 is connected to branch E. The hydraulic oil enters the oil inlet of self-propelled mold assembly 1 to self-propelled mold assembly 4 respectively. The hydraulic oil pressure P acts on the piston surface S of the clamping head, and the force F=P×S is generated, which overcomes the spring force in the clamping head and pushes the clamping head upward, thus realizing the mold clamping function. Conversely, when the mold needs to be relaxed, the signal is transmitted to the PLC, and the two-position four-way on branches C1 and C2 is in the right position and air intake is taken in. Then the two-position two-way solenoid valve at the front end of branches D and E is controlled to move to the left position, at which time branch B1 is connected to branch D, and branch B2 is connected to branch E. Then the hydraulic oil in the clamping head of self-propelled mold assembly 1 to self-propelled mold assembly 4 returns to the oil tank under the action of the clamping head spring force, and the spring force pushes the clamping head to move downward, thus realizing the mold relaxation function.

[0032] When the smaller mold on the slider needs to be clamped and relaxed in place, the signal is transmitted to the PLC. After receiving the instruction, the PLC first controls the two-position four-way solenoid valve on branches C1 and C2 to move to the right position for ventilation, and then pushes the two-position two-way solenoid valve on branches D and E to move to the left position. At this time, the clamping head on the self-propelled mold assembly 1 to the self-propelled mold assembly 4 moves downward under the action of the spring force and is in a relaxed state; the second step is to control the three-position four-way solenoid valve on the air source branch 1 to the air source branch 4 to move to the lower position for ventilation, and then the air source enters the air inlet 1 of the self-propelled mold assembly 1 to the self-propelled mold assembly 4 along the speed control valve 2, pushing the piston upward. Then drive the gear plate and chain to move upward. The chain pushes the clamping head back and forth from the G position to the F position along the T-type guide rail. After the clamping head reaches the F position, the proximity switch is powered off. The proximity switch transmits the signal that the clamping head has moved to the F position to the PLC. Then the PLC controls the three-position four-way solenoid valve to return to the middle position, ensuring that the clamping head is always stationary at the F position. When the mold needs to be clamped, the signal is transmitted to the PLC, and the PLC controls the two-position four-way on branches C1 and C2 to be in the left position without air intake. Because the two-position two-way solenoid valves at the front end of branches D and E are controlled by the two-position four-way solenoid valves of branches C1 and C2 respectively, the two-position two-way solenoid valves are stationary in the right position. Then branch A1 is connected to branch D, and branch A2 is connected to branch E. The hydraulic oil enters the oil inlet of self-propelled mold assembly 1 to self-propelled mold assembly 4 respectively. The hydraulic oil pressure P acts on the piston S of the clamping head, and the force F=P×S is generated, which overcomes the spring force in the clamping head and pushes the clamping head upward, thus realizing the mold clamping function. Conversely, when the mold needs to be relaxed, the signal is transmitted to the PLC, and the two-position four-way on branches C1 and C2 is in the right position and air intake is taken in. Then the two-position two-way solenoid valve at the front end of branches D and E is controlled to move to the left position, at which time branch B1 is connected to branch D, and branch B2 is connected to branch E. Then the hydraulic oil in the clamping head of self-propelled mold assembly 1 to self-propelled mold assembly 4 returns to the oil tank under the action of the clamping head spring force, and the spring force pushes the clamping head to move downward, thus realizing the mold relaxation function.

[0033] In the present invention, the control air circuits of the self-propelled mold assembly 1 to the self-propelled mold assembly 4 are in parallel and do not affect each other. Even if a three-position four-way solenoid valve on one of the air source branches fails, the other three self-propelled mold clamping groups can still work normally.

[0034] In the present invention, four self-propelled mold clamping components, two of which are diagonally opposite to each other, form a group, and use a cross anti-drop protection clamping circuit. That is, self-propelled mold clamping component three and self-propelled mold clamping component two form a group, and the oil inlet is controlled by a two-position two-way solenoid valve on branch D. Self-propelled mold clamping component one and self-propelled mold clamping component four form a group, and the oil inlet is controlled by a two-position two-way solenoid valve on branch E. Because self-propelled mold clamping component one and self-propelled mold clamping component two are installed in front of the slider, and self-propelled mold clamping component three and self-propelled mold clamping component four are installed behind the slider, a cross anti-drop protection clamping circuit is used to effectively ensure that even if one of the oil circuits is blocked, the other group of self-propelled mold clamping components at the front and rear diagonals of the slider can still be balanced and clamped, preventing the danger of the mold falling due to oil circuit failure and failure of the self-propelled mold clamping component.

[0035] In the present invention, speed control valve 1 and speed control valve 2 are installed on each of air source branch 1 to air source branch 4. The air intake size of air inlet 1 and air inlet 2 of self-propelled model assembly 1 to self-propelled model assembly 4 can be controlled by adjusting the speed control valve, thereby controlling the speed of the up and down movement of the piston in self-propelled model assembly 1 to self-propelled model assembly 4, and realizing the adjustable speed of the clamping head moving on the T-slot guide rail.
