Description

Technical Field

[0001] This utility model belongs to the field of heat treatment technology, and in particular relates to a heat treatment tray that is easy to fix. Background Technology

[0002] Heat treatment trays are tools used to support workpieces during the heat treatment process. They are usually made of high-temperature resistant materials, which can withstand high-temperature environments and ensure that the workpieces will not deform or be damaged during heating or cooling. They are widely used in the metal processing industry.

[0003] When not in use, traditional heat treatment trays can be stacked vertically. However, during use, the lower end of the current heat treatment tray can be inserted into the upper end of the adjacent heat treatment tray below it to prevent the two adjacent heat treatment trays from shifting horizontally in opposite directions, thus improving the stability between the two adjacent heat treatment trays.

[0004] A search revealed that authorization announcement number CN211570757U, authorized on September 25, 2020, discloses a heat treatment tray that is easy to fix, including a tray frame, an upper clamping post, a side tray, a side clamping strip, and a lower clamping cylinder. The upper part of the tray frame is threaded to the upper clamping post, and the tray frame is welded to the side tray. The inner diameter of the lower clamping cylinder of this utility model is interference-fitted with the outer diameter of the upper clamping post. After the heat treatment process is completed, the upper clamping post above one tray frame can be inserted into the lower clamping cylinder below another tray frame. Due to the side clamping groove provided in the middle of the upper clamping post, it can be properly clamped in the lower clamping cylinder, so that the two trays will not easily fall off and can be easily picked up. Similarly, multiple trays can be fixed in sequence in the above manner, saving space and making it easy to fix idle heat treatment trays.

[0005] In existing technologies, after heat treatment, it is necessary to remove the workpiece from the heat treatment tray. The common operation is to transfer the workpiece from the heat treatment tray to a regular tray. However, when removing the workpiece from the tray frame, for lighter workpieces, manual removal is often used. However, the tray frame has a certain height. When picking up the workpiece from the tray frame inside the frame, it is necessary to move the workpiece to a height higher than the upper wall of the tray frame before transferring it to a regular tray. This makes it impossible to move the workpiece horizontally for picking, and the operation is quite laborious. In addition, in existing technologies, after the upper clamp is inserted into the lower clamp of the adjacent heat treatment tray, the two adjacent heat treatment trays are in a relatively fixed horizontal state. However, when multiple stacked heat treatment trays accidentally tip over, the taller heat treatment tray will slide along the ground due to inertia, increasing the probability of the heat treatment tray hitting other objects around it. Therefore, we provide a heat treatment tray that is easy to fix to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a heat treatment tray that is easy to fix. A circular plate allows the placement plate to be moved outside the enclosure for workpiece retrieval. Inserts are used to connect the trays to corresponding rectangular columns, achieving a stable connection between two easily fixed heat treatment trays. This solves the problem in existing technologies where workpieces need to be moved to a height higher than the upper wall of the tray frame before being transferred to a regular tray, making horizontal movement of the workpiece difficult and laborious. Furthermore, in existing technologies, when multiple stacked heat treatment trays accidentally tip over, the taller tray will slide along the ground due to inertia, increasing the probability of the tray colliding with surrounding objects.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a heat treatment tray that is easy to fix, comprising a tray body, a placement plate, a surrounding enclosure, a side plate rotatably connected to the front wall of the enclosure via a hinge, mounting tubes fixed along the edges of the lower wall of the placement plate, vertical plates fixed at the front and rear ends of the lower wall of the mounting tube on the left and the front and rear ends of the lower wall of the mounting tube on the right, a circular plate on one side of the vertical plate, a rotating rod fixed at the middle of the circular plate, the rotating rod being rotatably connected to the vertical plate via a bearing; and a connecting assembly comprising a U-shaped frame fixed to the bottom of the inner side of the enclosure, rectangular columns fixed at the four corners of the lower wall of the U-shaped frame, U-shaped sleeves fixed at the four corners of the upper part of the placement plate, connecting plates on the left and right side walls of the placement plate, inserts fixed at the front and rear ends of the connecting plates, the inner ends of the inserts being inserted into the interior of the U-shaped sleeves.

[0009] The present invention is further configured such that multiple through slots are provided on the left and right side walls and the rear side wall of the enclosure, and multiple through slots are provided at equal intervals on the placement plate.

[0010] The present invention is further configured such that a rectangular groove is provided on the front wall of the fence at the location of the side plate, and end plates are fixed on both the left and right ends of the upper end of the rear wall of the side plate. Bolts are threadedly connected to the fence at the location of the end plates, and the inner end of the bolts is inserted into the interior of the end plates.

[0011] The present invention is further provided with a handle fixedly provided at the front end of the placement plate.

[0012] The present invention is further configured such that guide grooves are provided on both the left and right sides of the upper wall of the U-shaped frame, and the circular plate is located inside the corresponding guide groove.

[0013] The present invention is further configured such that a connecting rod is rotatably connected to the middle position of the connecting plate via a bearing, a spring is sleeved on the outside of the connecting rod, an L-shaped plate is provided at the end of the spring away from the connecting plate and fixed to the enclosure, and a handle is fixed at the end of the connecting rod away from the connecting plate.

[0014] The present invention is further configured such that a protrusion is fixed on the outer peripheral wall of the connecting rod, and an avoidance groove is provided on the L-shaped plate corresponding to the location of the protrusion.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up a placement plate, mounting tube, and circular plate, allows the workpiece to be placed on the upper surface of the placement plate during heat treatment. After heat treatment, the side plate is rotated until the rectangular groove is exposed. The operating handle allows the placement plate to be moved out of the enclosure under the action of the circular plate. At this time, when picking up the heat-treated workpiece, since the placement plate has moved outside the enclosure, the worker can move the workpiece horizontally on the upper surface of the placement plate and then move the workpiece to a regular tray. Compared with the existing technology that overcomes the workpiece's gravity by first moving the workpiece to a higher position and then placing it on a regular tray, this easy-to-fix heat treatment tray can reduce the labor burden when picking up the workpiece to a certain extent. At the same time, after moving the placement plate outside the enclosure, lifting the placement plate allows the workpiece to be quickly separated from the placement plate, making the turnover efficiency of this easy-to-fix heat treatment tray higher during use.

[0017] 2. This utility model, by setting inserts and U-shaped sleeves, allows the rectangular column to be inserted into the connecting component below the material tray body through operation, until the insert is inserted into the rectangular column. In this way, multiple heat treatment material trays that are easy to fix can be stacked along the height direction, and two adjacent heat treatment material trays that are easy to fix can be stably connected. With this connection method, when the stacked heat treatment material trays are tilted, due to the mutual connection between the adjacent heat treatment material trays, multiple heat treatment material trays that are easy to fix will not slide on the ground, reducing the damage area when tilting and reducing the probability of sliding on the ground and hitting other surrounding objects.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This is the first embodiment of the present invention. This embodiment provides a heat treatment tray that is easy to fix, including a tray body 1. The tray body 1 includes a placement plate 102 for placing heat-treated workpieces. A baffle 101 is provided on the outside of the placement plate 102 to prevent the workpieces from falling. A side plate 103 is rotatably connected to the front wall of the baffle 101 via a hinge 103a. The hinge 103a is located at the bottom of the side plate 103, allowing the side plate 103 to rotate relative to the baffle 101. Mounting tubes 102b are fixed along the edge of the lower wall of the placement plate 102. The mounting tubes 102b and adjacent mounting tubes 102b are connected by... The fixed connection between the two sides can prevent the placement plate 102 from deforming. Vertical plates 104 are fixed at both ends of the lower wall of the mounting tube 102b on the left side and at both ends of the lower wall of the mounting tube 102b on the right side. A circular plate 105 is provided on one side of the vertical plate 104. A rotating rod 105a is fixed at the middle position of the circular plate 105. The rotating rod 105a is rotatably connected to the vertical plate 104 through a bearing. The circular plate 105 can rotate relative to the placement plate 102, so that the placement plate 102 can be moved out of the enclosure under the action of the circular plate 105, thereby realizing the horizontal movement of the workpiece and placing the workpiece on the ordinary material tray.

[0032] Specifically, multiple through slots 101a are provided on the left and right side walls and the rear side wall of the enclosure 101, and multiple through slots 102a are provided at equal intervals on the placement plate 102. The through slots 101a and through slots 102a serve as heat transfer channels, so that the workpiece on the upper surface of the placement plate 102 is heated faster during heat treatment.

[0033] A rectangular groove 101b is provided on the front wall of the enclosure 101 at the location of the side plate 103. End plates 103b are fixed at both ends of the upper rear wall of the side plate 103. Bolts 106 are threaded onto the enclosure 101 at the location of the end plate 103b. The inner end of the bolt 106 is inserted into the interior of the end plate 103b. With the above configuration, the bolt 106 is disengaged from the corresponding end plate 103b. At this time, the side plate 103 is rotated and the end of the side plate 103 away from the hinge 103a contacts the ground. Under the action of the circular plate 105, the placement plate 102 moves through the rectangular groove 101b. With the help of the ramp provided by the side plate 103, the placement plate 102 can be moved to the outside of the enclosure 101. A handle 102c is fixed at the front end of the placement plate 102. The placement plate 102 can be moved by operating the handle 102c.

[0034] The operation process of this embodiment is as follows: When in use, the workpiece is placed above the placement plate 102, and the movement of the heat treatment tray that is easy to fix can be controlled to carry out heat treatment.

[0035] After heat treatment is completed, the heat treatment tray that is easy to fix is ​​moved to the ground, and the operating bolt 106 is disengaged from the end plate 103b. At this time, the operating side plate 103 is rotated and the end of the side plate 103 away from the hinge 103a is brought into contact with the ground. Then, the operating handle 102c is moved forward. At this time, under the action of the circular plate 105, the placement plate 102 passes through the rectangular groove 101b and moves forward. At this time, the circular plate 105 at the bottom of the placement plate 102 rolls in the guide groove 203b. With the help of the ramp provided by the side plate 103, the placement plate 102 is moved to the outside of the enclosure 101. Then, the workpiece on the upper surface of the placement plate 102 is moved to the surface of the ordinary tray.

[0036] After the workpiece is transferred to the surface of the placement plate 102, the placement plate 102 is moved into the enclosure 101 by operating the handle 102c under the action of the circular plate 105. Then, the side plate 103 is rotated to close the side plate 103. The bolt 106 is rotated and the inner end of the bolt 106 is inserted into the corresponding end plate 103b. The workpiece to be heat-treated is then placed on the placement plate 102 for heat treatment.

[0037] Example 2

[0038] Please see Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: the connecting component 2 includes a U-shaped frame 203 fixed to the bottom inner side of the enclosure 101. Rectangular posts 203a are fixed at the four corners of the lower wall of the U-shaped frame 203. U-shaped sleeves 201 are fixed at the four corners of the upper end of the placement plate 102. Connecting plates 202 are provided on both the left and right side walls of the placement plate 102. Inserts 202a are fixed at both the front and rear ends of the connecting plates 202. Figure 7 As shown, the insert 202a is a right-angled trapezoid. The length of the upper wall of the insert 202a is less than the length of the lower wall, resulting in an inclined surface at one end of the insert 202a when inserted into the rectangular column 203a. This inclined surface allows for the connection of two adjacent, easily fixed heat treatment trays. The rectangular column 203a in the easily fixed heat treatment tray can be directly inserted into the U-shaped sleeve 201 in the tray below, eliminating the need for manual operation to move the insert 202a away from the enclosure 101. This makes operation more convenient. When the inner end of the insert 202a is inserted into the U-shaped sleeve 201, and the rectangular column 203a is inserted into the U-shaped sleeve 201 in the easily fixed heat treatment tray below, the two easily fixed heat treatment trays are in a relatively fixed state under the action of the insert 202a.

[0039] Specifically, guide grooves 203b are provided on both the left and right sides of the upper wall of the circular frame 203. The circular plate 105 rolls along the guide grooves 203b to guide the circular plate 105. The circular plate 105 is located inside the corresponding guide groove 203b.

[0040] A connecting rod 205 is rotatably connected to the middle position of the connecting plate 202 via a bearing. A spring 205a is sleeved on the outside of the connecting rod 205 to apply a force to the connecting plate 202 in the direction of the enclosure 101, so as to prevent the insert 202a from accidentally detaching from the corresponding rectangular column 203a. An L-shaped plate 206 fixed to the enclosure 101 is provided at the end of the spring 205a away from the connecting plate 202. A handle 204 is fixed at the end of the connecting rod 205 away from the connecting plate 202. Operating the handle 204 can move the connecting plate 202 and also rotate the protrusion 205b on the connecting rod 205.

[0041] A protrusion 205b is fixed to the outer peripheral wall of the connecting rod 205. An clearance groove 206a is provided on the L-shaped plate 206 corresponding to the location of the protrusion 205b. Under normal conditions, the insert 202a is inserted into the rectangular column 203a, and the protrusion 205b is located inside the clearance groove 206a. However, when using this easy-to-fix heat treatment tray, since multiple easy-to-fix heat treatment trays are stacked when not in use, the handle 204 can be pulled away from the enclosure 101 to move the protrusion 205b away from the enclosure. Move the enclosure 101 in the direction of movement, and then rotate the second handle 204 at a certain angle, such as 90 degrees, to release the force on the second handle 204. At this time, the spring 205a provides support for the connecting plate 202 until the protrusion 205b is close to the end of the enclosure 101 and contacts the side wall of the L-shaped plate 206. At this time, the insert 202a is in a state of disengagement from the rectangular column 203a, and the uppermost heat treatment tray that is easy to fix can be moved up and disengaged from the adjacent heat treatment tray that is easy to fix, thus completing the removal of the idle heat treatment tray that is easy to fix.

[0042] The operation process of this embodiment is as follows: When multiple heat treatment trays that are easy to fix are idle, the rectangular column 203a in the heat treatment tray that is easy to fix is ​​inserted into the U-shaped sleeve 201 in the heat treatment tray that is easy to fix below it, until the connecting plate 202 is pushed towards the enclosure 101 under the action of the spring 205a, so that the insert strip 202a is inserted into the corresponding rectangular column 203a, thus achieving a stable connection between the two heat treatment trays that are easy to fix.

[0043] When it is necessary to remove the stacked heat treatment trays that are easy to fix, by operating one of the handles 204 on the topmost heat treatment tray, the tray is moved away from the enclosure 101 until the protrusion 205b moves to disengage from the clearance groove 206a. At this time, the insert 202a disengages from the rectangular post 203a. In this state, the handle 204 is rotated and then the action on the handle 204 is released. Under the action of the spring 205a, the protrusion 205b abuts against the L-shaped plate 206. At this time, the insert 202a is still disengaged from the rectangular post 203a. Then, the insert 202a on the other side is disengaged from the rectangular post 203a according to the above operation. This allows the two adjacent heat treatment trays that are easy to fix to be in a stackable state, thereby separating the two adjacent heat treatment trays that are easy to fix.
