Description

Technical Field

[0001] The present invention relates to the technical field of door lock panel molding equipment, and more particularly, to an automatic molding equipment and molding process for a door lock panel. Background Art

[0002] Door lock panel forming equipment is a special equipment used to manufacture door lock panels. It uses concave molds and convex molds to process metal materials (such as stainless steel, aluminum alloy, etc.) into panel structures that meet the requirements of smart locks or traditional locks.

[0003] Before stamping the panel, the existing door lock panel forming equipment needs to manually apply no-clean lubricant to locally lubricate the surface of the panel material to prevent strain, scratches and mold wear during the forming process. However, the manual application of no-clean lubricant has significant defects. First, the consistency of manual operation is poor, and problems such as uneven application thickness, local omissions or excessive application are prone to occur, resulting in insufficient or excessive lubrication. Insufficient lubrication will cause material tearing and abnormal mold wear, and excessive lubrication will cause the oil film to be too thick, which will interfere with subsequent surface treatment processes such as spraying and electroplating. Second, manual operation efficiency is low, and the lubricant applied in an open environment will cause serious volatilization loss, resulting in waste of resources and increased costs, and will also affect the overall production efficiency of the equipment.

[0004] The present invention provides an automated molding device and molding process for door lock panels, aiming to solve the problem of low efficiency and poor consistency of manual application of no-clean lubricating oil during panel molding, which leads to uneven lubrication and increased costs, thus affecting production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide an automated molding device and molding process for door lock panels, so as to solve the problem in the panel molding process proposed in the above background technology that the manual application of no-clean lubricating oil is inefficient and has poor consistency, resulting in uneven lubrication and increased costs, affecting production efficiency.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an automated molding device for a door lock panel, comprising a base, a stamping device, and a mold assembly, wherein the mold assembly comprises an upper mold base and a lower mold base, wherein the upper mold base has a groove at the bottom and a protrusion at the top of the lower mold base, and further comprising: An oil spray assembly is provided in the upper die base and is used for synchronously spraying lubricating oil onto the inner wall of the groove during the stamping process; an air jet assembly, disposed in the lower die base, for jetting gas toward the formed panel during the demoulding stage; The support assembly is arranged on the lower die base and is used to support the panel to be punched and to link the jet assembly.

[0007] Preferably, the oil injection assembly comprises: A profiling plate is slidably arranged in the groove, and a plurality of oil injection holes are evenly opened on its outer circumference; a slider, one end of which is fixedly connected to the contour plate and the other end of which is fixedly connected to the first piston member; A pressure chamber is provided in the upper die seat, and the first piston member slides in a sealed manner in the pressure chamber.

[0008] Preferably, an oil storage chamber is provided in the slider, and the oil storage chamber is connected to the pressure chamber through a pressure channel opened in the slider. A first one-way valve is provided in the pressure channel, which only allows the medium to flow from the pressure chamber to the oil storage chamber.

[0009] Preferably, a communication port communicating with the pressure chamber is formed on the side wall of the upper die base, and a second one-way valve is provided in the communication port for only allowing external lubricating oil to enter the pressure chamber.

[0010] Preferably, the jet assembly comprises: A profiled tube, the inner side of which is provided with an inclined air jet; An air storage cavity is provided in the lower die base and is connected to the contoured tube via a telescopic tube; The second piston member slides in a sealed manner in the air storage chamber.

[0011] Preferably, the support assembly comprises: The support plate is provided with an avoidance groove sleeved outside the protrusion, and the profiling tube is fixed to the top of the support plate; A limiting rod is vertically fixed to the top of the support plate; a support rod slidingly passing through the lower die base and fixedly connected to the second piston member; A second elastic member connects the support rod and the lower die base and is used for resetting the support plate.

[0012] Preferably, the diameter of the avoidance groove is larger than the diameter of the protrusion and smaller than the diameter of the door lock panel after molding.

[0013] Preferably, the diameter of the profiling plate is smaller than the diameter of the groove, and the spraying direction of the oil injection hole is toward the inner wall of the groove.

[0014] Preferably, a plurality of first elastic members are connected between the first piston member and the top of the pressure chamber.

[0015] An automated molding process for a door lock panel comprises the following steps: S1. Place the panel material on the support plate and position it using the limit rod; S2, start the driving device to push the upper die base downward, so that the profiling plate contacts the panel and triggers the oil spray assembly to spray lubricating oil; S3. After the convex block is completely pressed into the groove and the stamping is completed, the driving device is started to push the upper die seat upward; S4: When the upper die seat rises, the second elastic member pushes the support plate to lift the forming panel, and the gas in the gas storage cavity is blown through the air jet to purge the panel surface; S5.

On the one hand, the oil mist spraying and stamping can be carried out synchronously, reducing the loss of lubricating oil evaporation and improving production efficiency. On the other hand, the lubricating oil spraying amount can be automatically adjusted according to the moving distance of the panel during stamping, thereby avoiding problems such as uneven coating thickness, local omission or excessive coating, avoiding abnormal wear of the mold, and improving the panel forming accuracy and equipment service life. 2. The present invention arranges the jet assembly so that the outside can be drawn into the gas storage chamber for storage during the downward movement of the upper die base. When the upper die base completes the stamping work and moves upward, the gas stored in the gas storage chamber will be sprayed toward the formed door lock panel through the telescopic tube, the contoured tube and the jet port, thereby accelerating the volatilization rate of the no-clean lubricating oil. On the one hand, it can avoid affecting the subsequent spraying or welding process, so that the workpiece can enter the subsequent process faster, reduce waiting time, and further improve production efficiency. On the other hand, it can reduce the contact between the human body and the no-clean lubricating oil, reduce the potential harm to human health, and thus protect the health of the operator.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1 Before stamping the panel, the existing door lock panel forming equipment needs to manually apply no-clean lubricant to locally lubricate the surface of the panel material to prevent strain, scratches and mold wear during the forming process. However, the manual application of no-clean lubricant has significant defects. First, the consistency of manual operation is poor, and problems such as uneven application thickness, local omissions or excessive application are prone to occur, resulting in insufficient or excessive lubrication. Insufficient lubrication will cause material tearing and abnormal mold wear, and excessive lubrication will cause the oil film to be too thick, which will interfere with subsequent surface treatment processes such as spraying and electroplating. Second, manual operation efficiency is low, and the lubricant applied in an open environment will cause serious volatilization loss, resulting in waste of resources and increased costs, and will also affect the overall production efficiency of the equipment.

[0031] refer to Figures 1 to 11 , an automatic molding device for a door lock panel according to a first embodiment of the present invention includes a base 1, a stamping device 2 and a mold assembly 3.

[0032] refer to Figure 1 The stamping device 2 includes a driving device 21 arranged above the base 1, and a plurality of guide columns 22 are fixedly connected between the driving device 21 and the base 1. A lifting block 23 fixedly connected to the output end of the driving device 21 is slidably connected to the plurality of guide columns 22. The stamping device 2 is a prior art and will not be described in detail here.

[0033] refer to Figures 1 to 5 The mold assembly 3 includes an upper mold base 31 and a lower mold base 32. A groove 311 is provided at the bottom of the upper mold base 31, and a protrusion 322 corresponding to the position of the groove 311 is fixedly connected to the top of the lower mold base 32. When the upper mold base 31 moves downward, so that the protrusion 322 enters the inside of the groove 311, the groove 311 and the protrusion 322 can jointly limit and squeeze the metal sheet of the panel to be stamped, and can force the metal sheet of the panel to be stamped to form a three-dimensional structure of the panel in the groove 311. The mold assembly 3 is a prior art and will not be described in detail here.

[0034] refer to Figures 5 to 8 , further comprising a support assembly 4, which is arranged on the upper mold assembly 3, including a support plate 41, a through-shaped avoidance groove 42 is provided on the support plate 41, and the support plate 41 is sleeved on the outer peripheral side of the protrusion 322 through the avoidance groove 42, the diameter of the avoidance groove 42 is larger than the diameter of the protrusion 322, and smaller than the diameter of the panel after forming, and a plurality of limit rods 43 are fixedly connected to the top of the support plate 41, and the plurality of limit rods 43 are used to guide and limit the metal sheet of the panel to be stamped; The bottom of the support plate 41 is fixedly connected to a plurality of support rods 44, and the plurality of support rods 44 are slidably connected to the lower mold base 32, and a plurality of second elastic members 45 are provided between the support plate 41 and the lower mold base 32. The second elastic members 45 are used to reset the support plate 41. In the initial state, the support plate 41 is higher than the protrusion 322 under the support of the plurality of second elastic members 45.

[0035] refer to Figures 2 to 4 , also includes an oil injection assembly 5, which is arranged on the upper mold assembly 3, including a slider 51, one side of the slider 51 is fixedly connected to a profiling plate 52, and the other side is fixedly connected to a first piston member 53, the interior of the upper mold base 31 is provided with a pressure chamber 54 above the groove 311, and a guide groove that can communicate with each other is provided between the pressure chamber 54 and the groove 311, the first piston member 53 is sealingly and slidably connected in the pressure chamber 54, the slider 51 is slidably connected in the guide groove between the pressure chamber 54 and the groove 311, the profiling plate 52 is slidably located in the groove 311, the diameter of the profiling plate 52 is smaller than the diameter of the groove 311, and the outer peripheral side of the profiling plate 52 is evenly provided with a number of oil injection holes 55 facing the inner walls around the groove 311, and a plurality of first elastic members 511 are connected between the top of the first piston member 53 and the pressure chamber 54.

[0036] refer to Figure 3 and Figure 4 An oil storage chamber 56 connected to a plurality of oil injection holes 55 is provided inside the slider 51. A pressure channel 57 connecting the oil storage chamber 56 and the pressure chamber 54 is provided on the top of the slider 51. A first one-way valve 58 is provided in the pressure channel 57. A connecting port 59 connected to the interior of the pressure chamber 54 is provided on one side of the upper mold base 31. A second one-way valve 510 is provided in the connecting port 59. The connecting port 59 is connected to an external oil storage device through an oil pipe. The external oil storage device stores no-cleaning lubricating oil.

[0037] The first one-way valve 58 is used to allow the medium inside the pressure chamber 54 to enter the oil storage chamber 56 and prevent the medium in the oil storage chamber 56 from returning to the pressure chamber 54. The second one-way valve 510 is used to allow the lubricating oil in the external oil storage device to enter the pressure chamber 54 and prevent the medium in the pressure chamber 54 from entering the external oil storage device.

[0038] During actual operation, the metal sheet of the panel to be punched is first placed on the top of the support plate 41, and is guided and limited by a plurality of limiting rods 43 so that the metal sheet of the panel to be punched is located above the protrusion 322, and then the driving device 21 is started to drive the lifting block 23 and the upper die base 31 to move downward. Figure 10 , during the downward movement of the upper die base 31, its bottom will first contact the tops of the multiple limiting rods 43, thereby preferentially pushing the support plate 41 to move downward under the guidance of the multiple supporting rods 44 and compressing the multiple second elastic members 45, while reserving deformation space for the metal sheet of the panel to be stamped. During the downward movement of the multiple limiting rods 43, the metal sheet of the panel to be stamped can still be limited to prevent the metal sheet of the panel to be stamped from deflecting; Continuing to move the upper die base 31 downward will cause the profiling plate 52 to contact the metal sheet of the panel to be punched first, thereby pushing the profiling plate 52 to drive the slider 51 and the first piston member 53 to move upward in the pressure chamber 54. In the process of the slider 51 and the first piston member 53 moving upward in the pressure chamber 54, the air pressure in the pressure chamber 54 will increase. Due to the setting of the second one-way valve 510, the medium in the pressure chamber 54 cannot be discharged through the connecting port 59. The increased air pressure can only enter the oil storage chamber 56 through the pressure channel 57 and the first one-way valve 58, thereby pushing the no-cleaning lubricating oil in the oil storage chamber 56 to be sprayed out from the multiple oil spray holes 55, and forming an oil mist to be sprayed into the inside of the groove 311. Figure 11, the upper die base 31 continues to move downward, which will cause the groove 311 and the protrusion 322 to cooperate with each other to limit and squeeze the metal sheet of the panel to be stamped, and can force the metal sheet of the panel to be stamped to form a three-dimensional structure of the panel in the groove 311, and simultaneously push the profiling plate 52 to move upward, and evenly spray oil mist inside the groove 311 during the upward movement. On the one hand, the oil mist spraying and stamping can be carried out simultaneously, reducing the evaporation loss of lubricating oil and improving production efficiency. On the other hand, the lubricating oil injection amount can be automatically adjusted according to the panel stamping stroke, thereby avoiding problems such as uneven coating thickness, local omissions or excess, avoiding abnormal wear of the mold, and improving the panel forming accuracy and equipment service life.

[0039] After the panel is stamped and formed, the control drive device 21 drives the lifting block 23 and the upper mold base 31 to move upward. At this time, the multiple first elastic members 511 in the compressed state will push back the first piston member 53, the slider 51 and the contour plate 52 to move downward, and in the process of moving downward, the formed door lock panel will be pushed out of the groove 311 to complete the demoulding of the upper mold base 31. In the process of the upper mold base 31 moving upward, the upper mold base 31 no longer squeezes the support plate 41 through the multiple limit rods 43. The support plate 41 will move upward under the rebound action of the multiple second elastic members 45. Since the avoidance groove 42 is smaller than the diameter of the panel after forming, the support plate 41 can push the formed door lock panel on the protrusion 322 to move upward during the upward movement, completing the demoulding of the lower mold base 32, thereby completing the automatic demoulding of all molds, reducing the occurrence of safety accidents caused by manual operation, and improving production efficiency.

[0040] It should be noted that when the stamping work is completed, the driving device 21 drives the lifting block 23 and the upper mold base 31 to move upward, and the multiple first elastic parts 511 will push the first piston part 53 to move downward in the pressure chamber 54, which will cause the pressure chamber 54 to generate negative pressure. Due to the setting of the first one-way valve 58, the medium in the oil storage chamber 56 cannot enter the pressure chamber 54. At this time, the negative pressure in the pressure chamber 54 can only enter the external oil storage device through the connecting port 59, the second one-way valve 510 and the oil pipe, and the stamping-free lubricating oil in the external oil storage device is pumped into the pressure chamber 54, and after the negative pressure in the pressure chamber 54 disappears, it enters the oil storage chamber 56 through the pressure channel 57 and the first one-way valve 58, thereby automatically replenishing the lubricating oil for the oil injection work during the next stamping, thereby reducing manual operation and further improving production efficiency.

[0041] To sum up, through the setting of the oil spray component 5, the profiling plate 52 can be pushed to move upward synchronously during the stamping process of the door lock panel, and the oil mist can be evenly sprayed inside the groove 311 during the upward movement of the profiling plate 52. On the one hand, the oil mist spraying and stamping can be carried out synchronously, reducing the evaporation loss of lubricating oil and improving production efficiency. On the other hand, the lubricating oil spraying amount can be automatically adjusted according to the moving distance of the panel stamping, thereby avoiding problems such as uneven coating thickness, local omissions or excess, avoiding abnormal wear of the mold, and improving the panel forming accuracy and equipment service life.

[0042] Example 2 In the actual production process, since the evaporation rate of the no-clean lubricant is related to the ambient temperature, when the on-site ambient temperature is too low, the evaporation rate of the no-clean lubricant may be too slow, which may cause oil stains to remain and affect the subsequent spraying or welding process. Therefore, this embodiment improves the device described in the above embodiment.

[0043] refer to Figures 5 to 9 , also includes an air jet component 6, the air jet component 6 is arranged on the support component 4, and includes a profiling tube 61, the profiling tube 61 is fixedly connected to the top of the support plate 41, and a plurality of obliquely arranged air jet ports 62 are evenly opened on the inner side of the profiling tube 61, and the plurality of air jet ports 62 are used to blow air toward the formed rear panel.

[0044] refer to Figure 7 The interior of the lower mold base 32 is provided with air storage chambers 63, the same number as the support rods 44 and corresponding in position. Each air storage chamber 63 is sealed and slidably connected to a second piston member 64 fixedly connected to the corresponding support rod 44. The upper part of the air storage chamber 63 is connected to the contoured tube 61 through a telescopic tube, and the lower part of the air storage chamber 63 is connected to the external air.

[0045] During actual operation, when the upper mold base 31 pushes the support plate 41 to compress multiple second elastic members 45 to move downward, the support plate 41 will drive the corresponding second piston member 64 to move downward in the corresponding air storage chamber 63 through multiple support rods 44. During the downward movement of multiple second piston members 64, the outside will be drawn into the air storage chamber 63 through the jet port 62, the profiling tube 61 and the telescopic tube for air storage. When the upper mold base 31 completes the stamping work and moves upward, the multiple second elastic members 45 will push the support plate 41 back to move upward. During the upward movement of the support plate 41, the corresponding second piston member 64 will be driven to move upward in the corresponding air storage chamber 63 through multiple support rods 44, and the gas stored in the air storage chamber 63 will be sprayed to the formed door lock panel through the telescopic tube, the profiling tube 61 and the jet port 62, thereby accelerating the volatilization speed of the no-cleaning lubricant to avoid affecting the subsequent spraying or welding process.

[0046] To sum up, through the setting of the jet assembly 6, the external gas can be drawn into the gas storage chamber 63 for storage during the downward movement of the upper mold base 31. When the upper mold base 31 completes the stamping work and moves upward, the gas stored in the gas storage chamber 63 will be sprayed toward the formed door lock panel through the telescopic tube, the contoured tube 61 and the jet port 62, thereby accelerating the volatilization rate of the no-clean lubricating oil. On the one hand, it can avoid affecting the subsequent spraying or welding process, so that the workpiece can enter the subsequent process faster, reduce waiting time, and further improve production efficiency. On the other hand, it can reduce the contact between the human body and the no-clean lubricating oil, reduce the potential harm to human health, and thus protect the health of the operator.

Place the panel material on the support plate 41 and position it using the limiting rod 43; S2, start the driving device 21 to push the upper die holder 31 downward, so that the profiling plate 52 contacts the panel and triggers the oil spraying assembly 5 to spray lubricating oil; S3, after the protrusion 322 is completely pressed into the groove 311 and the stamping is completed, the driving device 21 is started to push the upper die holder 31 upward; S4, when the upper mold base 31 rises, the second elastic member 45 pushes the support plate 41 to lift the molding panel, and the gas in the gas storage chamber 63 is blown through the air jet 62 to sweep the panel surface; S5. Cut the formed door lock panel.
