Description

Technical Field

[0001] The present application relates to the technical field of quenching equipment, and in particular to a tool quenching equipment for centralized quenching. Background Art

[0002] Quenching is a heat treatment process. Quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), kept at this temperature for a period of time to make it fully or partially austenitized, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to undergo martensite (or bainite) transformation. The solid solution treatment or heat treatment process with rapid cooling process of materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass is usually called quenching.

[0003] The existing patent (Announcement No.: CN217948200U) discloses a batch quenching tool quenching equipment, including a quenching box, a tool to be quenched, a water tank is arranged at the bottom of the quenching box, and water inlet pipes are connected between the two sides of the bottom of the water tank and the two sides of the middle of the quenching box. The inner walls on both sides of the quenching box are fixedly connected with multiple main nozzles, and the middle of the inner side of the quenching box is provided with multiple tool hangers, the tool hanger includes a base frame, and the two sides of the center top of the base frame are fixedly connected with baffles, and the tops of the four corners of the base frame are fixedly connected with multiple inclined baffle groups. A seat block is arranged at the center of the inner top of the quenching box, and the bottom ends of the front and back of the seat block are fixedly connected with threaded rods, and the external threads of the threaded rods are connected with multiple threaded rings. The utility model can perform comprehensive cooling work on multiple tools to be quenched by making the cooling water sprayed by the main nozzle spray from between two adjacent tools to be quenched that are inclined relative to the inner walls on both sides of the quenching box, which is conducive to improving the quality and efficiency of the tools to be quenched after batch quenching.

[0004] The above technical solution solves the problem that when quenching batches of tools, uneven cooling may lead to an increase in the tool scrap rate, which is not conducive to improving the tool production efficiency. However, the above technical solution only places the tool to be quenched between two adjacent inclined baffle groups on the tool hanger, and uses baffle bars to limit the movement of the tool to be quenched. It is difficult to effectively fix the tool to be quenched on the tool hanger. During the quenching process, the tool to be quenched may still slide away from the baffle bar under the action of the coolant spray, thereby causing the tool to be quenched to fall off the tool hanger, causing damage to the tool. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a centralized quenching tool quenching equipment, which has the advantages of stable tool fixation, etc., and solves the problem of unstable tool fixation in the prior art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a centralized quenching tool quenching equipment, comprising a box body, and a box door hinged on the front side of the box body, a vertical shaft is arranged inside the box body along the height direction, the vertical shaft is rotatably connected to the box body, and cross bars are evenly fixed on the outer surface of the vertical shaft located inside the box body, a number of tool clamping devices are arranged inside each cross bar, a motor is arranged at the top end of the vertical shaft, and a spray device is evenly arranged on the inner wall of the box body.

[0007] Through the above scheme, when in use, the tool is placed on the cross bar, and then the tool is fixed by the tool clamping device to prevent movement during quenching, and then the box door is closed, and the tool inside the box is sprayed and quenched by the spray device. At the same time, the motor drives the vertical shaft to rotate, and the vertical shaft drives the tool to rotate through the cross bar, so that the spray water flow can be sprayed on the tool as evenly as possible, preventing the tool from being easily cooled unevenly during spray quenching, resulting in an increase in the tool scrap rate, which is not conducive to improving the production efficiency of the tool.

[0008] Furthermore, a through vertical hole parallel to the length direction of the cross bar is formed on the upper end surface of the cross bar, and a plurality of tool clamping devices are arranged inside the vertical hole of the cross bar along the length direction of the cross bar.

[0009] According to the above scheme, when in use, the tool is first inserted into the cross bar through the vertical hole, and then each tool is fixed and clamped by the tool clamping device to facilitate quenching.

[0010] Furthermore, a through hole parallel to the length direction of the cross bar is formed on the outer side surface of the cross bar, and the tool clamping device is slidably arranged in the through hole along the length direction of the cross bar.

[0011] Through the above scheme, when in use, the tool clamping device will clamp and fix the tool inserted into the vertical hole of the cross bar, and the spray water will spray quench the tool. The perforation setting increases the area of ​​the tool sprayed by the spray water, improves the quality of quenching, and facilitates the setting of the tool clamping device.

[0012] Furthermore, the tool clamping device comprises two slide blocks which are slidably arranged in the through hole along the length direction of the cross bar, and a spring is arranged between the two slide blocks.

[0013] Through the above scheme, when in use, the tool is inserted between the sliders of two adjacent tool clamping devices, and the tool also needs to be inserted between the tool clamping device at the edge of the crossbar and the end wall of the vertical hole of the crossbar. The tool is clamped by the cooperation of the slider of the tool clamping device at the edge and the end wall of the vertical hole; when the crossbar is full of tools, the tool clamping device clamps all the tools on the crossbar through the spring and the slider. Then, the tools on the crossbar inside the box can be sprayed and quenched by the spray device, and at the same time, the motor drives the vertical shaft to rotate, and then drives the tool to rotate through each crossbar, so that the amount of water received by the tools for quenching is as balanced as possible.

[0014] Furthermore, two adjustment blocks are arranged between the two sliders of each tool clamping device, and the two adjustment blocks are both slidably arranged in the through hole along the length direction of the cross bar. Two springs are arranged respectively between the adjustment blocks and the sliders; a driving device is arranged between the two adjustment blocks, and the driving device is used to drive the two adjustment blocks to move away from each other.

[0015] Through the above scheme, during use, when the tool is clamped by the slider, when the width of the tool is small and the clamping force of the two sliders on the tool is small, the two adjustment blocks are driven to move away from each other by the driving device, and the spring is compressed, so that the clamping force of the slider on the tool is increased, thereby ensuring the stability of the tool being fixed and preventing the problem of insufficient clamping force when the width of the tool is small, and easy falling off during quenching.

[0016] Furthermore, the driving device includes a driving block slidably arranged in the vertical hole, the two side surfaces of the driving block contacting the two adjustment blocks are arranged as first inclined surfaces, and the top of a side surface close to the two adjustment blocks is provided with a second inclined surface.

[0017] Through the above scheme, when the driving block moves downward, it contacts the second inclined surfaces of the two adjustment blocks respectively through the two first inclined surfaces. When the driving block continues to move downward, the driving block drives the two adjustment blocks to move away from each other through the first inclined surfaces and the second inclined surfaces, compressing the spring, thereby increasing the clamping force of the slider on the tool.

[0018] Furthermore, two vertical rods are arranged in the vertical hole of the crossbar at positions corresponding to the driving blocks, and the driving blocks are connected to the two vertical rods in an upward and downward sliding manner.

[0019] Through the above solution, when the driving block slides up and down, it slides up and down on the two vertical rods, thereby increasing the stability of the movement of the driving block.

[0020] Furthermore, a top rod is arranged between the two vertical rods, the internal thread of the top rod is connected with a threaded rod, and the bottom end of the threaded rod is rotatably connected to the driving block.

[0021] Through the above solution, when the driving block needs to be slid up and down, the threaded rod is rotated to drive the driving block to slide up and down between the two vertical rods.

[0022] Furthermore, ventilation blocks are provided at both ends of the crossbar, a through channel is provided on the upper end surface of the ventilation block, the vertical holes and through holes of the crossbar are connected to the channel, and a plurality of ventilation holes connected to the channel are provided on the outer side surface of the ventilation block.

[0023] Through the above scheme, when in use, the spray water will enter the vertical holes and perforations of the crossbar through the air-permeable block or the channel to quench the tool, thereby improving the quality of the tool quenching.

[0024] Furthermore, a positioning block is provided on the inner bottom wall of the perforation of the crossbar at a position corresponding to the driving block.

[0025] Through the above solution, when the slider and the adjusting block are moved, when the adjusting block moves to the positioning block, it will be prevented from moving, thereby playing a role in positioning the adjusting block.

[0026] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0027] The tool quenching equipment for centralized quenching is provided with a vertical shaft, a motor, a spraying device, a cross bar, and a tool fixing device. When the device is used, the tool is placed in the cross bar and fixed by the tool fixing device so that the tool is firmly fixed. Then, the tool on the cross bar is quenched by the spraying device. At the same time, the vertical shaft is driven to rotate by the motor, so that the vertical shaft drives the tool to rotate through the cross bar, so that the spraying water flow can be sprayed onto the tool as evenly as possible, so as to achieve the purpose of firmly fixing the tool when quenching the tool.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] See also Figure 1 - Fig.10 A tool quenching equipment for centralized quenching in this embodiment includes a box body 1 and a box door 2 hinged on the front side of the box body 1. A vertical shaft 3 is arranged inside the box body 1 along the height direction. The vertical shaft 3 is rotatably connected to the box body 1. A cross bar 4 is evenly fixed on the outer surface of the vertical shaft 3 located inside the box body 1. A plurality of tool clamping devices are arranged inside each cross bar 4. A motor 5 is arranged at the top of the vertical shaft 3. A spray device 6 is evenly arranged on the inner wall of the box body 1.

[0042] When in use, the tool 7 is placed on the cross bar 4, and then the tool 7 is fixed by the tool clamping device to prevent it from moving during quenching. Then the box door 2 is closed, and the tool 7 inside the box body 1 is spray quenched by the spray device 6. At the same time, the motor 5 drives the vertical shaft 3 to rotate, and the vertical shaft 3 drives the tool 7 to rotate through the cross bar 4, so that the spraying water flow can be sprayed on the tool 7 as evenly as possible, preventing the tool 7 from being easily cooled unevenly during spray quenching, resulting in an increase in the scrap rate of the tool 7, which is not conducive to improving the production efficiency of the tool 7.

[0043] In this embodiment, the upper end surface of the cross bar 4 is provided with a through vertical hole 8 parallel to the length direction of the cross bar 4, and a plurality of tool clamping devices are arranged inside the vertical hole 8 of the cross bar 4 along the length direction of the cross bar 4; when in use, the tool 7 is first inserted into the cross bar 4 through the vertical hole 8, and then each tool 7 is fixed and clamped by the tool clamping device to facilitate quenching.

[0044] Since the cross bar 4 has a certain height, a part of the tool 7 located inside the cross bar 4 will be blocked by the height of the cross bar 4, affecting the tool 7 being sprayed by the sprayed water. In order to reduce the influence of the cross bar 4 on the quenching of the tool 7 and facilitate the setting of the tool clamping device, in this embodiment, the outer side surface of the cross bar 4 is provided with a through hole 9 parallel to the length direction of the cross bar 4, and the tool clamping device is slidably set in the hole 9 along the length direction of the cross bar 4; when in use, the tool clamping device clamps and fixes the tool 7 inserted into the vertical hole 8 of the cross bar 4, and the spray water sprays and quenches the tool 7. The setting of the hole 9 increases the area of ​​the tool 7 sprayed by the spray water, improves the quality of quenching, and facilitates the setting of the tool clamping device.

[0045] The tool clamping device includes two sliders 10 that are slidably arranged in the through hole 9 along the length direction of the cross bar 4, and a spring 11 is arranged between the two sliders 10; when in use, the tool 7 is inserted between the sliders 10 of the two adjacent tool clamping devices, and the tool 7 also needs to be inserted between the tool clamping device at the edge of the cross bar 4 and the end wall of the vertical hole 8 of the cross bar 4, and the tool 7 is clamped by the cooperation of the slider 10 of the tool clamping device at the edge and the end wall of the vertical hole 8; when the cross bar 4 is full of tools 7, the tool clamping device clamps all the tools 7 on the cross bar 4 through the spring 11 and the slider 10. Then, the tools 7 on the cross bar 4 inside the box 1 can be sprayed and quenched by the spray device 6, and at the same time, the motor 5 drives the vertical shaft 3 to rotate, and then drives the tool 7 to rotate through each cross bar 4, so that the amount of water received by the tool 7 for quenching is as balanced as possible.

[0046] Since the width of the tool 7 has various specifications, when the tool 7 is clamped using the above solution, the tools 7 of different widths are clamped with different forces. The tool 7 with a small width is clamped with a small force and is easy to loosen, while the tool 7 with a large width is clamped with a large force. In order to solve this problem, in this embodiment, two adjustment blocks 12 are arranged between the two sliders 10 of each tool clamping device. The two adjustment blocks 12 are both slidably arranged in the through hole 9 along the length direction of the cross bar 4. Two springs 11 are arranged, which are respectively arranged between the adjustment blocks 12 and the sliders 10. A driving device is provided between the two adjusting blocks 12, and the driving device is used to drive the two adjusting blocks 12 to move away from each other; when in use, when the tool 7 is clamped by the slider 10, when the width of the tool 7 is small and the clamping force of the two sliders 10 on the tool 7 is small, the two adjusting blocks 12 are driven to move away from each other by the driving device, and the spring 11 is compressed, so that the clamping force of the slider 10 on the tool 7 is increased, thereby ensuring the stability of the tool 7 being fixed and preventing the tool 7 from falling off easily during quenching due to insufficient clamping force when the width of the tool 7 is small.

[0047] In this embodiment, the driving device includes a driving block 13 that is slidably arranged in the vertical hole 8. The two side surfaces of the driving block 13 that contact the two adjusting blocks 12 are set as first inclined surfaces 14, and the top of the side surface close to the two adjusting blocks 12 is provided with a second inclined surface 15 that is adapted to the first inclined surface 14; when the driving block 13 moves downward, it contacts the second inclined surfaces 15 of the two adjusting blocks 12 respectively through the two first inclined surfaces 14. When the driving block 13 continues to move downward, the driving block 13 drives the two adjusting blocks 12 to move away from each other through the first inclined surface 14 and the second inclined surface 15, compressing the spring 11, so that the clamping force of the slider 10 on the tool 7 increases.

[0048] In order to increase the stability of the driving block 13 sliding up and down, in this embodiment, two vertical rods 16 are provided in the vertical hole 8 of the cross bar 4 at positions corresponding to the driving block 13, and the driving block 13 is connected to the two vertical rods 16 for up and down sliding; when the driving block 13 slides up and down, it slides up and down on the two vertical rods 16, thereby increasing the stability of the movement of the driving block 13.

[0049] In order to facilitate the purpose of driving the driving block 13 to slide up and down, in this embodiment, a top rod 17 is arranged between the two vertical rods 16, and the internal thread of the top rod 17 is connected to a threaded rod 18, and the bottom end of the threaded rod 18 is rotatably connected to the driving block 13; when the driving block 13 needs to be slid up and down, the threaded rod 18 is rotated to drive the driving block 13 to slide up and down between the two vertical rods 16.

[0050] During actual use, the two end portions of the two cross bars 4 will also have an adverse effect on the quenching of the tool 7. In order to solve this problem, in the present embodiment, both ends of the cross bar 4 are provided with air permeable blocks 19, the upper end surface of the air permeable block 19 is provided with a through channel 20, the vertical holes 8 and the through holes 9 of the cross bar 4 are connected to the channel 20, and the outer side surface of the air permeable block 19 is provided with a plurality of air permeable holes 21 connected to the channel 20; when in use, the spray water will pass through the air permeable block 19 or the channel 20 into the vertical holes 8 and the through holes 9 of the cross bar 4, so as to quench the tool 7 and improve the quenching quality of the tool 7.

[0051] In order to achieve the purpose of positioning the tool clamping device, in this embodiment, a positioning block 22 is provided on the inner bottom wall of the through hole 9 of the cross bar 4 at a position corresponding to the driving block 13. When the slider 10 and the adjusting block 12 are moved, when the adjusting block 12 moves to the positioning block 22, it will be prevented from moving, thereby playing a role in positioning the adjusting block 12.

[0052] The working principle of the above embodiment is as follows: when in use, the tool 7 is inserted into the vertical hole 8 of each cross bar 4, so that the tool 7 is located between the sliders 10 of two adjacent tool clamping devices, and the tool 7 is clamped by the slider 10 of the tool clamping device. When the width of the tool 7 is small and the clamping force of the slider 10 on the tool 7 through the spring 11 is small, the driving block 13 is driven to move downward by rotating the threaded rod 18, so that the driving block 13 drives the two adjustment blocks 12 to move away from each other through the first inclined surface 14 and the second inclined surface 15, and the spring 11 is compressed, so that the clamping force of the slider 10 on the tool 7 is increased, thereby ensuring the stability of the tool 7 being fixed, and preventing the tool 7 from falling off easily during quenching due to insufficient clamping force when the width of the tool 7 is small, and then the box door 2 is closed, and the tool 7 on the cross bar 4 is sprayed and quenched by the spray device 6. At the same time, the motor 5 drives the vertical shaft 3 to rotate, so that the vertical shaft 3 drives each tool 7 to rotate through the cross bar 4, and then drives the tool 7 to rotate through each cross bar 4, so that the amount of water received by the tool 7 for quenching is as balanced as possible.
