Description

Technical Field

[0001] The utility model relates to the technical field of stamping equipment, in particular to a metal cold stamping equipment. Background Art

[0002] Cold stamping equipment is used to perform stamping processing on metal or non-metal materials at room temperature. Its working principle is to apply pressure to the material through the die installed on the press, causing it to separate or plastically deform, thereby obtaining parts or products with the required shape, size and performance. The main feature of the cold stamping production process is that it relies on the die and stamping equipment to complete the processing.

[0003] With regard to the existing related technologies, it is believed that the following defects exist: cold stamping equipment is mass-produced and processed when stamping and forming molds, and a mold needs to be used repeatedly. The mold needs to be oiled and maintained in time after long-term use, and the existing cold stamping equipment mostly adopts manual oiling and maintenance after shutdown. This method is inefficient and there is a great risk for workers working in the cold stamping equipment; therefore, a metal cold stamping equipment is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the utility model proposes a metal cold stamping equipment.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a metal cold stamping equipment described in the utility model comprises a cold stamping machine, a mold is provided on one side of the cold stamping machine, a servo motor is fixedly installed on one side of the cold stamping machine, a screw rod is fixedly installed on the output end of the servo motor, a sleeve frame is movably connected to the surface of the screw rod, a cavity is opened inside the sleeve frame, a base is fixedly installed on one side of the cold stamping machine, an oil storage box is fixedly installed on the top of the base, a water pump is fixedly installed inside the oil storage box, an oil guide pipe is fixedly installed on one end of the water pump, an oil injection pipe is provided on one side of the sleeve frame, one end of the oil guide pipe passes through the cavity of the sleeve frame and is connected to the oil injection pipe; a telescopic component for assisting the oil injection pipe to move is provided inside the sleeve frame.

[0007] Furthermore, the telescopic assembly includes an electric push rod fixedly installed in a sleeve frame, a rectangular frame is fixedly installed on the output end of the electric push rod, the fuel injection pipe and the rectangular frame are fixedly connected, and a rubber scraper is fixedly installed on one side of the sleeve frame close to the fuel injection pipe.

[0008] Furthermore, a bracket is fixedly installed on one side of the cold stamping machine, a storage groove is provided on one side of the bracket, a hollow elastic block is fixedly installed inside the storage groove, an air duct connected to the inside of the elastic block is fixedly installed on the top of the bracket, a fixed block is fixedly installed on one side of the sleeve frame, an air outlet hole is provided on one side of the fixed block, an end of the air duct away from the elastic block is connected to the air outlet hole in the fixed block, and an extrusion block is fixedly installed on the top of the sleeve frame, and the extrusion block is in the storage groove.

[0009] Furthermore, a plurality of inclined guide plates are fixedly mounted on a side of the fixing block close to the air outlet, and the plurality of guide plates are arranged in groups of two and are symmetrically distributed about the central axis of the air outlet.

[0011] The utility model is beneficial in that:

[0012] 1. After the mold of the cold stamping machine has been used for a long time, the utility model starts the servo motor, uses the servo motor to drive the screw rod and the sleeve frame to move, and at the same time starts the water pump in the oil storage box, uses the water pump to pump the lubricating oil in the oil pump box into the oil injection pipe through the oil guide pipe, and uses the pressure of the lubricating oil filled into the oil injection pipe to make the hollow tube in the oil injection pipe slide toward the slide groove away from the sleeve frame. As the oil injection pipe unfolds, the oil outlet at the bottom thereof will also be opened, and the lubricating oil will be broken up by the protective net when spraying out through the oil outlet, thereby avoiding the gushing of the lubricating oil, and making the lubricating oil flow out in the form of small water droplets. As the sleeve frame moves with the oil injection pipe, the electric push rod in the cavity will also start at the same time, and then the electric push rod will move back and forth with the oil injection pipe away from the sleeve frame, thereby compensating for the defect that the oil injection pipe is not long enough, resulting in the mold being difficult to lubricate in the direction away from the sleeve frame. At the same time, the scraper is used to clean the reciprocating and telescopic output rod of the electric push rod to reduce the adhesion of impurities and affect the normal use of the electric push rod. The servo motor and the electric push rod are used in coordination to achieve the effect of oiling and lubricating molds of different sizes, thereby ensuring that the mold can maintain efficient work during cold stamping. At the same time, it can also eliminate the safety hazards of staff entering the cold stamping machine for oiling maintenance, greatly improving the efficiency and safety of cold stamping machine maintenance.

[0013] 2. The utility model drives the squeezing block on the top to move together when the sleeve frame moves, and utilizes the squeezing block to squeeze the elastic block in the storage groove, so that the gas in the elastic block enters the air outlet of the fixed block through the air guide pipe and is ejected, and utilizes the ejected gas to disperse the outflowing lubricating oil, so that the lubricating oil can lubricate all around, thereby avoiding the situation that only local lubrication below the oil outlet can be performed, resulting in incomplete maintenance.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 As shown, a metal cold stamping equipment includes a cold stamping machine 1, a mold 2 is provided on one side of the cold stamping machine 1, a servo motor 3 is fixedly installed on one side of the cold stamping machine 1, a screw rod 4 is fixedly installed on the output end of the servo motor 3, a sleeve frame 5 is movably connected to the surface of the screw rod 4, a cavity 9 is opened inside the sleeve frame 5, a base 6 is fixedly installed on one side of the cold stamping machine 1, an oil storage box 7 is fixedly installed on the top of the base 6, a water pump is fixedly installed inside the oil storage box 7, an oil guide pipe 8 is fixedly installed on one end of the water pump, an oil injection pipe 13 is provided on one side of the sleeve frame 5, one end of the oil guide pipe 8 passes through the cavity 9 of the sleeve frame 5 and is connected to the oil injection pipe 13, and a telescopic component for assisting the oil injection pipe 13 to move is provided inside the sleeve frame 5.

[0025] Specifically, the fuel injection pipe 13 is composed of a plurality of hollow tubes that are sealed and slidably connected. An elastic connecting rope 14 is fixedly installed between two hollow tubes. An oil outlet 15 is opened at the bottom of the fuel injection pipe 13. A protective net 16 is fixedly installed on the inner wall of the oil outlet 15. The telescopic component includes an electric push rod 10 fixedly installed in the sleeve frame 5. A rectangular frame 12 is fixedly installed at the output end of the electric push rod 10. The fuel injection pipe 13 and the rectangular frame 12 are fixedly connected. A scraper 11 made of rubber is fixedly installed on one side of the sleeve frame 5 close to the fuel injection pipe 13.

[0026] During operation, after the mold 2 of the cold stamping machine 1 has been used for a long time, the servo motor 3 is started, and the servo motor 3 is used to drive the screw rod 4 and the sleeve frame 5 to move. At the same time, the water pump in the oil storage box 7 is started, and the lubricating oil in the oil pump box is pumped into the oil injection pipe 13 through the oil guide pipe 8 by the water pump. The pressure of the lubricating oil filled into the oil injection pipe 13 makes the hollow tube in the oil injection pipe 13 slide toward the slide groove away from the sleeve frame 5. As the oil injection pipe 13 unfolds, the oil outlet 15 at the bottom thereof will also be opened, and the lubricating oil will be dispersed by the protective net 16 when spraying out through the oil outlet 15, thereby avoiding the gushing of the lubricating oil, and making the lubricating oil flow out in the form of small water droplets. As the sleeve frame 5 moves with the oil injection pipe 13, the electric push rod 10 in the cavity 9 will also start at the same time, and then the electric push rod 10 will move back and forth with the oil injection pipe 13 away from the sleeve frame 5, thereby compensating for the defect that the oil injection pipe 13 is not long enough, resulting in the mold 2 being difficult to lubricate in the direction away from the sleeve frame 5. At the same time, the scraper 11 is used to clean the reciprocating output rod of the electric push rod 10 to reduce the adhesion of impurities that affect the normal use of the electric push rod 10. The servo motor 3 and the electric push rod 10 are used in cooperation to achieve the effect of oiling and lubricating molds 2 of different sizes, thereby ensuring that the mold 2 can maintain efficient work during cold stamping. At the same time, it can also eliminate the safety hazards of staff entering the cold stamping machine 1 for oiling maintenance, thereby greatly improving the efficiency and safety of maintenance of the cold stamping machine 1.

[0027] A bracket 17 is fixedly installed on one side of the cold stamping machine 1, and a storage groove 18 is opened on one side of the bracket 17. A hollow elastic block 19 is fixedly installed inside the storage groove 18. An air guide tube 20 connected to the inside of the elastic block 19 is fixedly installed on the top of the bracket 17. A fixed block 21 is fixedly installed on one side of the sleeve frame 5. An air outlet 22 is opened on one side of the fixed block 21. One end of the air guide tube 20 away from the elastic block 19 is connected to the air outlet 22 in the fixed block 21. An extrusion block 23 is fixedly installed on the top of the sleeve frame 5. The extrusion block 23 is in the storage groove 18. A plurality of inclined guide plates 24 are fixedly installed on one side of the fixed block 21 close to the air outlet 22. The plurality of guide plates 24 are symmetrically distributed in groups of two about the central axis of the air outlet 22.

[0028] During operation, when the sleeve frame 5 moves, it will drive the squeezing block 23 on the top to move together, and use the squeezing block 23 to squeeze the elastic block 19 in the storage groove 18, so that the gas in the elastic block 19 enters the air outlet 22 of the fixed block 21 through the air guide pipe 20 and is sprayed out, and the sprayed gas is used to disperse the outflowing lubricating oil, so that the lubricating oil can lubricate the surroundings, thereby avoiding only local lubrication below the oil outlet 15, resulting in incomplete maintenance.

[0029] A rectangular plate 25 is fixedly mounted on one side of the sleeve frame 5 , and a brush 26 is fixedly mounted on the bottom of the rectangular plate 25 .

[0030] During operation, when the sleeve frame 5 moves again, it will move with the rectangular plate 25 and the brush 26, and the brush 26 will be used to apply the lubricating oil on the surface of the mold 2 again, so that the entire mold 2 can be evenly covered with lubricating oil, effectively reducing the defects of uneven spraying of lubricating oil and lack of lubricating oil maintenance at the corners of the mold 2.

[0031] Working principle: after the mold 2 of the cold stamping machine 1 has been used for a long time, the servo motor 3 is started, and the servo motor 3 is used to drive the screw rod 4 and the sleeve frame 5 to move. At the same time, the water pump in the oil storage box 7 is started, and the lubricating oil in the oil pump box is pumped into the oil injection pipe 13 through the oil guide pipe 8 by the water pump. The pressure of the lubricating oil filled into the oil injection pipe 13 makes the hollow tube in the oil injection pipe 13 slide toward the slide groove away from the sleeve frame 5. As the oil injection pipe 13 unfolds, the oil outlet 15 at its bottom will also be opened, and the lubricating oil will be dispersed by the protective net 16 when spraying out through the oil outlet 15, thereby avoiding the gushing of the lubricating oil, and making the lubricating oil flow out in the form of small water droplets. As the sleeve frame 5 moves with the oil injection pipe 13, the electric push rod 10 in the cavity 9 will also start at the same time, and then the electric push rod 10 will move back and forth with the oil injection pipe 13 away from the sleeve frame 5, thereby compensating for the defect that the oil injection pipe 13 is not long enough, resulting in the mold 2 being difficult to lubricate in the direction away from the sleeve frame 5. At the same time, the scraper 11 is used to clean the reciprocating output rod of the electric push rod 10 to reduce the adhesion of impurities that affect the normal use of the electric push rod 10. The servo motor 3 and the electric push rod 10 are used in cooperation to achieve the effect of oiling and lubricating molds 2 of different sizes, thereby ensuring that the mold 2 can maintain efficient work during cold stamping. At the same time, it can also eliminate the safety hazards of staff entering the cold stamping machine 1 for oiling maintenance, thereby greatly improving the efficiency and safety of maintenance of the cold stamping machine 1.

[0032] When the sleeve frame 5 moves, it will drive the squeezing block 23 on the top to move together, and use the squeezing block 23 to squeeze the elastic block 19 in the storage groove 18, so that the gas in the elastic block 19 enters the air outlet 22 of the fixed block 21 through the air guide pipe 20 and sprays out, and the sprayed gas is used to blow away the outflowing lubricating oil, so that the lubricating oil can lubricate the surroundings. At the same time, the sleeve frame 5 will move with the rectangular plate 25 and the brush 26, and use the brush 26 to apply the lubricating oil on the surface of the mold 2 again, so that the entire mold 2 can be evenly covered with lubricating oil.
