Description

Technical Field

[0001] The invention relates to the technical field of hammer production equipment, in particular to crusher hammer production equipment and a production process thereof. Background Art

[0002] The hammer head is a wear-resistant part of a crusher, which is usually used to hammer and crush the materials entering the crusher. Therefore, it needs to be made of wear-resistant materials. The existing hammer heads are usually produced by hot pressing to make them have high wear resistance. After forging, the lower die cavity needs to be cleaned and lubricated. However, the existing punch press has the following disadvantages and shortcomings when forging the hammer head:

[0003] After forging, the inner cavity of the lower die is difficult to clean, and there are dead corners that are difficult to clean. The dead corners need to be cleaned manually by high-pressure washing, which is time-consuming and laborious;

[0004] During forging, the heated blank is placed on the lower die and will oxidize in the air to produce debris and impurities, affecting the surface quality after stamping. Summary of the invention

[0005] Aiming at the deficiencies in the prior art, the present invention provides crusher hammer production equipment and a production process thereof.

[0006] In order to solve the above technical problems, the present invention solves them through the following technical solutions: crusher hammer production equipment includes a frame, an upper mold and a lower mold.

[0009] The upper mold is provided with an adsorption rod, and the adsorption rod is provided with an electromagnet that can drive the adsorption plate to lift upward;

[0010] The nozzle is connected with an inclined block, a driving sleeve matched with the inclined block is fixed on the frame, a movable cavity for sliding the inclined block is arranged in the push rod, and a first spring is arranged between the inclined block and the push rod.

[0011] In the above solution, preferably, a second spring is provided between the pull plate and the frame.

[0012] In the above scheme, preferably, the frame is provided with a cylinder body for providing liquid to the nozzle, the cylinder body is provided with a piston, the cylinder body includes a liquid supply chamber and an air supply chamber, the liquid supply chamber is connected to the nozzle, and the piston is connected to the adsorption rod through a piston rod.

[0013] In the above solution, preferably, the liquid supply chamber is connected to a liquid storage tank.

[0014] In the above solution, preferably, a plurality of air spray pipes for purging the blank are provided on the upper die. When the upper die slides downward, the air supply cavity is connected to the air spray pipes through a first one-way valve.

[0015] In the above solution, preferably, a plurality of return holes are provided on the ejector rod. The return holes are connected to a filter box. The filter box is connected to the air supply cavity through a second one-way valve. When the upper die is lifted, the air supply cavity sucks the return holes through the second one-way valve.

[0016] In the above solution, preferably, a connecting plate connected to the piston rod is provided on the adsorption rod. A first button cooperating with the connecting plate is provided on the frame. The first button is electrically connected to the electromagnet.

[0017] In the above solution, preferably, a plurality of support rods abutting against the pull plate are provided on the frame.

[0018] In the above solution, preferably, an inclined surface is provided on the inclined block. When the ejector rod slides up and down, the inclined surface on the inclined block cooperates with the driving sleeve to realize the lateral sliding of the nozzle.

[0019] In the above solution, preferably, the production process of the crusher hammer head production equipment is as follows:

[0020] S1: Place the hammer head blank on the lower die cavity. At this time, the upper end of the ejector rod is adapted to the surface of the lower die cavity, and then start the punching machine;

[0021] S2: The upper die slides downward, causing the piston to slide downward. The air supply cavity is squeezed to discharge high-pressure gas through the first one-way valve through the air spray pipes, so that the upper die purges the surface of the blank during the downward sliding process;

[0022] S3: While S2 is in progress, the liquid supply cavity is sucked to pump the liquid in the liquid storage tank into the liquid supply cavity;

[0023] S4: The upper die slides down to the lowest position and cooperates with the lower die to press the hammer head blank into a hammer head. At the same time, the electromagnet on the adsorption rod adsorbs the adsorption plate, and then the upper die is lifted upward;

[0024] S5: After the adsorption plate is adsorbed and lifted, it drives the pull plate to lift upward through the pull rope, causing the ejector rod to lift upward. The upper end of the ejector rod ejects the hammer head from the die cavity. At the same time, the inclined block on the nozzle in the ejector rod disengages from the cooperation with the driving sleeve. The first spring pulls the inclined block to place the nozzle outside the ejector rod. At the same time, the piston is lifted upward to squeeze the liquid supply cavity to eject the liquid through the nozzle, cleaning and lubricating the lower die cavity;

[0025] S6: While S5 is being carried out, the cleaned liquid flows back through the return holes on the ejector rod. When the piston moves upward, a negative pressure is generated in the air supply chamber, and the return holes are suctioned through the second one-way valve, causing the liquid to quickly enter the filter box through the return holes;

[0026] S7: When the upper die rises to the topmost position, the formed hammer head is completely ejected. At the same time, the first button triggers the electromagnet to cut off the power, causing the adsorption plate to disengage from adsorption. The ejector rod resets under the action of the second spring. During the reset process of the ejector rod, the inclined block guides and squeezes through the drive sleeve, causing the spray head to slide horizontally into the ejector rod.

[0027] The beneficial effects of the present invention are as follows: The present invention provides a hammer head production device that can blow the blank during the stamping of the hammer head, eject the formed hammer head while the forming stamping is completed, and clean the die cavity without dead angles. At the same time, the liquid after cleaning can be quickly collected by reflux, greatly improving the production efficiency of the hammer head and the product quality of the hammer head.

[0031] The following further describes the present invention in detail in conjunction with the drawings and the specific embodiments: Refer to Figures 1 - 3 , a crusher hammer head production device, including a frame 1, an upper die 2 and a lower die 3. The upper die 2 is slidably arranged on the frame 1 through a drive cylinder. The lower die 3 is fixedly arranged on the frame 1 and is located below the upper die 2. This is the existing structure of a punching press and will not be elaborated here. A die cavity adapted to the hammer head is provided on the lower die 3. When the upper die 2 and the lower die 3 cooperate, the blank placed on the lower die 3 can be formed into a hammer head.

[0032] An ejector rod 4 penetrating through the frame 1 is arranged in the lower die 3. A joint surface adapted to the die cavity of the lower die 3 is provided at the upper end of the ejector rod 4, that is, the ejector rod 4 is slidably arranged on the lower die 3 and the frame 1. A pull plate 6 is provided at the lower end of the ejector rod 4. A support rod 43 abuting against the pull plate 6 is arranged on the frame 1. The support rod 43 is preferably arranged on both sides of the ejector rod 4.

[0033] When the lower end surface of the pull plate 6 fits with the upper end of the support rod 43, the upper end of the ejector rod 4 is combined with the inner surface of the die cavity of the lower die 3 to form an integral stamping cavity, that is, at this time, when the blank is placed on the lower die 3, a complete hammer head can be formed through the stamping of the upper die 2.

[0034] One side of the pulling plate 6 is connected with an adsorption plate 8 through a pulling rope 7. The pulling rope 7 passes through the machine frame 1 and is fixedly connected with the adsorption plate 8 at the end face of the machine frame 1. The adsorption plate 8 is preferably an iron plate with strong ferromagnetism. In order to eject the formed hammer head through the ejector rod 4 after stamping, an adsorption rod 9 is arranged on the upper die 2. An electromagnet 10 capable of attracting the adsorption plate 8 is arranged at the lower end of the adsorption rod 9. When the upper die 2 slides down to the lowest end, the electromagnet 10 on the adsorption rod 9 can attract the adsorption plate 8, that is, the adsorption plate 8 is adsorbed by the electromagnet 10 while stamping. Then the upper die 2 completes stamping and slides upward. At this time, the electromagnet 10 drives the adsorption plate 8 to slide upward to move the pulling plate 6 upward, so that the ejector rod 4 is pushed upward to eject the hammer head in the cavity of the lower die 3.

[0035] A second spring 15 is arranged between the pulling plate 6 and the machine frame 1. The second spring 15 is sleeved on the ejector rod 4 and its two ends respectively abut against the machine frame 1 and the upper end face of the pulling plate 6. As Figure 1 shown, the ejector rod 4 is a hollow tube with a sealed upper end and a through lower end. A driving sleeve 12 matched with the inner hole of the ejector rod 4 is fixedly arranged on the machine frame 1. The ejector rod 4 can slide on the driving sleeve 12 during up and down displacement.

[0036] A plurality of nozzles 5 for spraying liquid are arranged in the ejector rod 4. The liquid is preferably a lubricating liquid. The nozzles 5 are preferably arranged in 2 - 6 groups evenly around the circumference of the ejector rod 4. The nozzles 5 are preferably universal nozzles, that is, the connection part between the nozzle 5 and the pipe fitting is a universal adjusting head, so that the spraying angle of the nozzle 5 can be adjusted. As Figure 2 shown, the nozzles 5 are horizontally slidably arranged at the upper end of the ejector rod 4. An inclined block 11 is arranged on one side of the nozzle 5 close to the center of the ejector rod 4. An inclined surface 51 is arranged on the inclined block 11. The inclined surface 51 inclines downward and toward the center of the ejector rod 4. An inclined block 11 is fixedly arranged below one side of the nozzle 5 close to the center of the ejector rod 4, and a guide plate 101 is fixedly arranged above. An activity cavity 13 for the inclined block 11 and the guide plate 101 to move is arranged in the ejector rod 4. A first spring 14 is arranged between the guide plate 101 and the inner cavity wall of the activity cavity 13 of the ejector rod 4. The first spring 14 is preferably a tension spring. A guide rod 102 matched with the guide plate 101 is fixedly arranged on the inner cavity wall of the activity cavity 13, that is, the nozzle 5 can slide on the guide rod 102 through the guide plate 101, so as to realize the horizontal displacement of the nozzle 5, that is, move the nozzle 5 into the activity cavity 13 or move it out of the ejector rod 4.

[0037] Initially, the inner hole of the drive sleeve 12 is in contact with the straight wall on the side of the inclined block 11 away from the center of the ejector rod 4. When the ejector rod 4 slides upward, that is, when the ejector rod 4 pushes the formed hammer head upward, the inner hole of the drive sleeve 12 disengages from the contact with the inclined block 11. At this time, the inclined block 11 drives the nozzle 5 under the tension of the first spring 14 to slide the nozzle 5 to the outside of the ejector rod 4, so that the nozzle 5 sprays and cleans the corners in the mold cavity.

[0038] A cylinder block 21 for supplying liquid to the nozzle 5 is provided on the frame 1. A piston 22 is provided in the cylinder block 21. The piston 22 divides the cylinder block 21 into a liquid supply chamber 23 and a gas supply chamber 24. The liquid supply chamber 23 is provided above the piston 22, and the gas supply chamber 24 is provided below the piston 22. A piston rod 25 is fixedly provided on the upper end surface of the piston 22. The piston rod 25 passes through the cylinder block 21 upward and is fixedly connected to the adsorption rod 9 through a connecting plate 41, that is, when the adsorption rod 9 rises or slides down, the piston 22 can be driven to rise or slide down synchronously.

[0039] The liquid supply chamber 23 is connected to the nozzle 5. A one-way valve flowing from the liquid supply chamber 23 to the nozzle 5 is provided between the liquid supply chamber 23 and the nozzle 5. The liquid supply chamber 23 is connected to a liquid storage tank 26. A one-way valve flowing from the liquid storage tank 26 to the liquid supply chamber 23 is provided between the liquid storage tank 26 and the liquid supply chamber 23. That is, when the piston 22 slides downward, the liquid supply chamber 23 is under negative pressure to suck the liquid in the liquid storage tank 26. When the piston 22 slides upward, the liquid supply chamber 23 is squeezed to eject the liquid in the liquid supply chamber 23 through the nozzle 5.

[0040] A plurality of air spray pipes 31 for purging the surface of the blank when the upper mold 2 slides downward are provided on both sides of the upper mold 2. The gas supply chamber 24 is connected to the air spray pipes 31 through a first one-way valve 32. The flow direction of the first one-way valve 32 is from the gas supply chamber 24 to the air spray pipes 31. That is, when the upper mold 2 slides downward and drives the piston 22 to slide downward to squeeze the gas supply chamber 24 through the adsorption rod 9, the gas supply chamber 24 ejects the pressurized gas through the air spray pipes 31 to purge the surface of the blank.

[0041] A plurality of return holes 33 are provided on the outer wall of the ejector rod 4. The return holes 33 communicate with the inner cavity of the ejector rod 4. The return holes 33 are provided below the nozzle 5. A drain hole connected to the inner cavity of the ejector rod 4 is provided on the pull plate 6. That is, after the ejector rod 4 is ejected, the liquid sprayed by the nozzle 5 can be collected by flowing back through the return holes 33 on the ejector rod 4 and discharged through the drain hole. The drain hole is connected to a filter tank 34. The filter tank 34 is connected to the gas supply chamber 24 through a second one-way valve 35. The flow direction of the second one-way valve 35 is from the filter tank 34 to the gas supply chamber 24. When the upper mold 2 is lifted, the piston 22 is driven to slide upward through the adsorption rod 9, so that a negative pressure is generated in the gas supply chamber 24. At this time, the gas supply chamber 24 sucks the return holes 33 through the filter tank 34, accelerating the return and filtering the recovered liquid at the same time.

[0042] A first button 42 that cooperates with the connecting plate 41 is provided on the frame 1. The first button 42 is electrically connected to the electromagnet 10. That is, initially, when the upper die 2 is at the uppermost position, the first button 42 cooperates with the connecting plate 41. At this time, the first button 42 is triggered, causing the electromagnet 10 to be powered off. When the upper die 2 slides down, the first button 42 disengages from the contact with the connecting plate 41. At this time, the electromagnet 10 is powered on. When the upper die 2 slides down to the lowermost position, the electromagnet 10 adsorbs the adsorption plate 8. Subsequently, after the upper die 2 completes stamping, it drives the adsorption plate 8 to lift, causing the ejector rod 4 to lift synchronously, ejecting the stamping hammer head and cleaning the cavity of the lower die 3 at the same time.

[0043] The production process of the crusher hammer head production equipment is as follows:

[0044] S1: Place the hammer head blank on the cavity of the lower die 3. At this time, the upper end of the ejector rod 4 is adapted to the surface of the cavity of the lower die 3. Subsequently, start the punching press;

[0045] S2: The upper die 2 slides downward. The upper die 2 drives the adsorption rod 9 and the connecting plate 41 to slide downward synchronously, thereby causing the piston 22 to slide downward. The cavity of the air supply chamber 24 is squeezed, and high-pressure gas is discharged through the spray pipe 31 through the first one-way valve 32, so that the upper die 2 purges the surface of the blank during the downward sliding process;

[0046] S3: While S2 is being carried out, the piston 22 slides downward, causing a negative pressure in the liquid supply chamber 23. The liquid supply chamber 23 is suctioned to draw the liquid in the liquid storage tank 26 into the liquid supply chamber 23;

[0047] S4: The upper die 2 slides down to the lowest position and cooperates with the lower die 3 to press the hammer head blank into a hammer head. At the same time, the electromagnet 10 on the adsorption rod 9 adsorbs the adsorption plate 8. Subsequently, the upper die 2 is lifted upward;

[0048] S5: After the adsorption plate 8 is adsorbed and lifted, it drives the pull plate 6 to lift upward through the pull rope 7, causing the ejector rod 4 to lift upward. The upper end of the ejector rod 4 ejects the hammer head from the cavity. At the same time, the inclined block 11 on the spray head 5 in the ejector rod 4 disengages from the cooperation with the driving sleeve 12. The first spring 14 pulls the inclined block 11 to place the spray head 5 outside the ejector rod 4. At the same time, the piston 22 is lifted upward to squeeze the liquid supply chamber 23, causing the liquid to be sprayed out through the spray head 5. While the ejector rod 4 is rising, the spray head 5 continuously sprays liquid during the rising process, cleaning and lubricating the cavity of the lower die 3 without dead angles;

[0049] S6: While S5 is being carried out, the cleaned liquid flows back through the return hole 33 on the ejector rod 4. When the piston 22 is lifted upward, it causes a negative pressure in the air supply chamber 24 and sucks the return hole 33 through the second one-way valve 35, causing the liquid to quickly enter the filter box 34 through the return hole 33;

[0050] S7: When the upper die 2 rises to the topmost position, the formed hammer head is completely ejected. At the same time, the first button 42 triggers the electromagnet 10 to cut off the power supply, causing the adsorption plate 8 to be disengaged from adsorption. The ejector rod 4 is reset under the action of the second spring 15. During the reset process of the ejector rod 4, the inclined block 11 is guided and extruded through the driving sleeve 12, causing the nozzle 5 to slide horizontally into the ejector rod 4.
