Description

Technical Field

[0001] The utility model relates to the technical field of quenching equipment, in particular to a container for placing die forgings and a quenching device using the container. Background Art

[0002] Quenching is a heat treatment process in which the die forging is heated to above the critical temperature, kept at this temperature for a certain period of time, and then cooled at a rate greater than the critical cooling rate to obtain a martensite or bainite structure. In order to achieve a sufficient cooling effect, there is a Chinese utility model patent with patent number CN202220527895.4 (authorization announcement number CN217173802U) in the prior art that discloses a "Die Forging Manufacturing Quenching Device". When the quenching device is used, the die forging is placed in a quenching cage, which is driven to move at a constant speed in the quenching tank to quench the die forging. The quenching water is driven by a water pump to circulate between the quenching tank and the circulating water tank, and the quenching water is cooled by an exhaust fan to improve the quenching effect.

[0003] The structure of the quenching cage is composed of a frame, which is more suitable for the case where the die forgings are small. Figure 1 When the die forging shown in the figure is used, the following problems will occur when the above-mentioned quenching device is applied: the die forging includes a die forging body 1' and a flash 2' surrounding the die forging body 1'. The existence of the flash 2' causes the overall die forging to be larger in size, and the shape of the flash 2' is irregular. If the above-mentioned quenching cage is used as a container for placing the die forging, since the peripheral walls of the frame are all regular plate-shaped, first, the quenching cage will need to be adaptively expanded due to the large size and irregularity of the die forging, which will cause the structure of the quenching pool to also need to be expanded, and finally This ultimately results in the overall quenching device being too large, increasing manufacturing costs. Second, even if the specifications of the quenching cage are sufficient to accommodate the die forgings, when batches of die forgings need to be quenched, multiple die forgings need to be stacked in the quenching cage. The die forgings to be quenched at high temperature are in a highly elastic state, and when stacked, they are easily squeezed against each other and deformed, increasing the rejection rate of die forging production. Third, different batches of die forgings to be quenched have different specifications. In order to match die forgings of different specifications, quenching cages of different specifications need to be customized and replaced, which is time-consuming and labor-intensive.

[0004] Therefore, faced with the limitation of using a quenching cage for the above-mentioned die forgings, the applicant directly adopted a method of quenching with a robot. For example, the "A Deburring System" with patent number 2023216447630 mentions that a loading robot clamps the die forgings to be quenched and places them into a quenching device for quenching. After quenching is completed, a unloading robot clamps the quenched die forgings out of the quenching device. Since the quenching device lacks a structure similar to a "quenching cage", the die forgings are placed in the quenching device in a scattered manner. Although this can avoid the problem of adapting to different sizes, there is still a problem of stacking of die forgings. Utility Model Content

[0005] The first technical problem to be solved by the present invention is to provide a container for each die forging to be placed independently and capable of cooperating with a loading robot to fall into place, in response to the above-mentioned existing technical status, which is particularly suitable for the case where the die forgings are large in size.

[0006] The second technical problem to be solved by the present invention is to provide a container that can adapt to die forgings of different specifications in different batches in response to the above-mentioned existing technical status.

[0007] The third technical problem to be solved by the present invention is to provide a quenching device using the above-mentioned receiving member in response to the above-mentioned existing technical status, so as to avoid the stacking problem that may occur between die forgings.

[0008] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: the container for placing the die forgings includes a bracket assembly, which is characterized in that: the bracket assembly includes a base, a first frame and a second frame arranged on the base, and a guide part that can perform initial guidance when the die forgings to be quenched are placed in place, the first frame and the second frame are arranged relative to each other and surround to form a placement area for placing the die forgings to be quenched, and the guide part is arranged on the first frame and / or the second frame.

[0009] To address the second technical problem, the first and second frames include at least one support leg, each of which comprises, from top to bottom, an upper section and a lower section. The guide portion is provided at the end of the upper section, while the lower section is connected to the base via an adjustment mechanism. The adjustment mechanism allows for adjustment of the position of the support leg, thereby enabling adaptive adjustment based on the specifications of die forgings in different batches.

[0010] In order to enable the adjustment mechanism to adjust the position of the legs, the adjustment mechanism preferably includes an extension platform extending outward from the lower section and an adjustment platform located below the extension platform. The extension platform and / or the adjustment platform are provided with adjustment holes along the Y-axis and X-axis of the base. In this way, the relative position of the first frame and the second frame on the X-axis and the Y-axis can be adjusted through the adjustment holes, thereby adjusting the size of the placement area formed by the first frame and the second frame, thereby accommodating different specifications of die forgings to be quenched.

[0011] Furthermore, the adjustment hole includes a first adjustment hole defined on the extension platform and extending along the Y-axis of the base. Correspondingly, a mounting hole is defined on the adjustment platform, and a limit screw is mounted in the mounting hole. The limit screw is threaded into the mounting hole, with its head exposed outside the first adjustment hole for easy adjustment. The first adjustment hole allows for adjustment of the distance between the first and second frames, thereby adjusting the width of the mounting area to accommodate forgings of varying thicknesses to be quenched.

[0012] Furthermore, the adjustment hole includes a second adjustment hole formed on the adjustment platform and along the X-axis of the base. When the stop screw and the second adjustment hole are connected, the extension platform can be fixed at a desired adjustment position in the X-axis. The second adjustment hole can adjust the fixed position of the first frame and / or the second frame on the X-axis of the base, thereby adjusting the length of the placement area to accommodate forgings of different sizes to be quenched.

[0013] Because the flash is thinner than the die forging body, it cannot support the die forging's mass after it is seated. To prevent deformation of the flash due to excessive force during quenching, the bracket assembly preferably includes a positioning portion for supporting and positioning the lower portion of the target die forging. The positioning portion is provided in the placement area and connected to the base or support leg via a first connector. In this way, the positioning portion can support the lower portion of the die forging, preventing the entire die forging from being pressed against the flash and causing deformation.

[0014] To detect whether the die forging to be quenched is properly seated, the support assembly preferably further includes a detection mechanism for detecting whether the target die forging is properly seated. The detection mechanism is connected to the base via a second connector and faces the seating area. The detection mechanism is configured to detect whether the die forging is properly seated when loaded and to generate an alarm if it is not.

[0015] The technical solution adopted by the present utility model to solve the above third technical problem is as follows: The quenching device includes a quenching tank and a receiving member disposed in the quenching tank for placing die forgings, and is characterized in that: the receiving member includes the above-mentioned bracket assembly, the base is provided with a mounting portion for mounting to the quenching tank at a portion outside the first frame body and the second frame body, and at least two bracket assemblies are arranged at intervals along the length direction of the quenching tank.

[0016] In order to prevent the quenching liquid in the quenching tank from flowing out of the quenching tank due to oversized die forgings, preferably, a partition plate is provided in the quenching tank, and the partition plate divides the quenching tank into a quenching pool and an overflow pool. The relationship between the height H1 of the partition plate and the height H2 of the side wall of the quenching pool is: H1 < H2, so that when the water level of the quenching liquid in the quenching pool is higher than H1, the quenching liquid flows from the quenching pool into the overflow pool. An outlet is also provided in the overflow pool. When the water level of the quenching liquid is too high and flows into the overflow pool, the quenching liquid is diverted to the waste liquid treatment device through the outlet.

[0017] In order to detect the temperature of the quenching liquid in the quenching pool, preferably, a temperature measuring device for detecting the temperature of the quenching liquid in the quenching pool is provided in the quenching pool. If the detected temperature is higher than the preset temperature, the circulation speed of the quenching liquid is increased to reduce the temperature in the quenching pool and ensure the quenching effect.

[0018] Compared with the prior art, the advantages of the present utility model are as follows:

[0019] 1. The receiving member for placing die forgings in the present utility model is designed as a bracket assembly. Each bracket assembly can independently place a die forging, avoiding the deformation of die forgings caused by stacking of die forgings, and realizing preliminary guidance for the positioning of the die forgings to be quenched by setting a guiding portion on the bracket, so as to effectively cooperate with the feeding robot to place the die forgings to be quenched into the quenching device, which can only be placed in a specific direction under program control;

[0020] 2. The present utility model also provides a quenching device including at least two bracket assemblies, which can realize quenching of multiple die forgings simultaneously and improve the quenching efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

When the limiting screw and the second adjustment hole 1732 are connected, the extension platform 171 can be fixed at the required adjustment position in the X-axis direction. By adjusting the first adjustment hole 1731 and the second adjustment hole 1732, the relative positions of the first frame 12 and the second frame 13 on the X-axis and the Y-axis can be adjusted, and then the size of the placement area 15 surrounded by the first frame 12 and the second frame 13 can be adjusted, so that different specifications of die forgings to be quenched can be placed.

[0032] The bracket assembly 1 also includes a positioning portion 18 that supports and positions the lower portion of the target die forging, and a detection mechanism 19 that verifies that the target die forging is properly seated. The positioning portion 18 is connected to the legs 16 of the second frame 13 via a first connector, providing support for the lower portion of the target die forging and preventing deformation of the die forging from pressing against the flash. The detection mechanism 19 is connected to the base 11 via a second connector and faces the placement area 15.
