[0035] Furthermore, the advantage of the present invention over the existing heat treatment equipment is that by providing a storage plate 3, three groups of partitions 4, four groups of side baffles 6 and two groups of top baffles 7 for use in combination, it is possible to achieve alternate loading and unloading of materials at both ends, thereby reducing loading and unloading time and improving production efficiency, and the equipment remains sealed during the loading and unloading process, which not only reduces heat loss and temperature fluctuations during the heat treatment process, maintains the stability of the heat treatment environment, but also improves the working environment comfort of the staff and reduces the risk of thermal damage.

[0036] like Figure 1-Figure 6 As shown, the main driving device includes a sleeve 8, a driven push rod 9, an L-shaped push plate 10, a driving screw 11, a left stand 12 and a right stand 13. The left stand 12 and the right stand 13 are both fixedly arranged on the upper end surface of the support platform 1. One end of the driving screw 11 is mounted on the right stand 13 for limited rotation. The other end of the driving screw 11 passes through the left stand 12 and is fixedly connected to the rotating motor. The L-shaped push plate 10 is mounted on the support platform 1 for limited sliding, and an internal screw hole for accommodating the driving screw 11 is opened on the L-shaped push plate 10. The sleeve 8 is fixedly arranged on the side plate of the partition 4, one end of the driven push rod 9 is fixedly connected to the L-shaped push plate 10, the other end of the driven push rod 9 extends into the sleeve 8 and is fixedly connected to the limiting disk, a notch 29 is opened on the lower end surface of the L-shaped push plate 10 close to the left vertical frame 12, the other end of the L-shaped push plate 10 is abutted and connected with an arc-shaped protrusion 14, the arc-shaped protrusion 14 extends into the support platform 1 and is fixedly connected to the limiting block 15, and the limiting block 15 is connected to the pushing assembly.

[0037] Furthermore, by providing the sleeve 8 , the driven push rod 9 can move behind the arc-shaped protrusion 14 and then push the partition plate 4 to move.

[0038] Specifically, by turning on the rotating motor, it drives the driving screw 11 to rotate. Under the screwing action of the internal and external threads, the L-shaped push plate 10 is forced to drive the driven push rod 9 to move horizontally. In this process, the right end of the L-shaped push plate 10 first acts on the arc-shaped protrusion 14, so that the arc-shaped protrusion 14 is forced to drive the limit block 15 to move downward, and then the driven push rod 9 will push the partition 4 to move horizontally.

[0039] like Figure 6-Figure 8 As shown, the push assembly includes an active push bar 18, a driven push frame 19, a No. 1 spring 20, an active rack 21 and an active gear 22. The driven push frame 19 is limitedly slidably installed in the support platform 1. One end of the active push bar 18 is fixedly connected to the driven push frame 19. The other end of the active push bar 18 is penetrated by a first inclined groove 17, and a cylindrical pin 16 is inserted in the first inclined groove 17. The cylindrical pin 16 is fixedly connected to the limit block 15. Two groups of No. 1 springs 20 are fixedly arranged on the side of the driven push frame 19 away from the active push bar 18, and four groups of active racks 21 are fixedly arranged on the driven push frame 19. Each group of active racks 21 is meshed and connected with a group of active gears 22. A vertical shaft 23 is fixedly inserted in each group of active gears 22. The upper end of the vertical shaft 23 penetrates the side baffle 6 and extends into the heat treatment box 2 to be connected to the linkage assembly. The vertical shaft 23 is fixedly connected to the side baffle 6.

[0040] Furthermore, by using the cylindrical pin 16, the active push bar 18, the driven push frame 19, the No. 1 spring 20, the active rack 21, the active gear 22 and the vertical rotating shaft 23 in cooperation, the up and down movement of the limit block 15 can be converted into the synchronous 90° forward and reverse rotation movement of the four groups of side baffles 6, so that the side baffles 6 can be adaptively opened or closed according to the movement state of the storage plate 3. While ensuring that the equipment remains sealed during the feeding and unloading process, the workpiece can be normally placed on the storage plate 3.

[0041] Specifically, the cylindrical pin 16 on the downward-moving limit block 15 acts on the first inclined slot 17, so that the active push bar 18 is forced to squeeze the No. 1 spring 20 to move to the right, and the active rack 21 on the active push bar 18 acts on the active gear 22, so that the vertical rotating shaft 23 drives the side baffle 6 to rotate inward 90° and form a vertical angle with the storage plate 3.

[0042] like Figure 5 as well as Figure 8As shown, the linkage assembly includes a driven gear 24, a reversing rack 25, a driven rack 26, a reversing gear 27 and a transverse rotating shaft 28. The driven gear 24 is fixedly sleeved on the top of the vertical rotating shaft 23. The driven gear 24 is meshedly connected to the reversing rack 25. The lower end of the reversing rack 25 is fixedly provided with a driven rack 26. The lower end of the driven rack 26 is meshedly connected to the reversing gear 27. The interior of the reversing gear 27 is fixedly plugged with a transverse rotating shaft 28, and the exterior of the transverse rotating shaft 28 is fixedly sleeved with a top baffle 7.

[0043] Specifically, when the vertical rotating shaft 23 rotates, the driven gear 24 thereon acts on the reversing rack 25, causing the reversing rack 25 to be forced to move horizontally, and the driven rack 26 at the bottom of the reversing rack 25 acts on the reversing gear 27, causing the horizontal rotating shaft 28 to drive the top baffle 7 to perform a 90° up and down flip movement.

[0044] like Figure 8-Figure 11 As shown, the side wall of the top baffle 7 is abutted and connected with a resistance block 30, which extends into the heat treatment box 2 and is fixedly connected with a connecting bar 31. The connecting bar 31 is installed in the heat treatment box 2 for limited sliding and is connected to the pushing assembly, and an S-shaped spring piece 33 is fixedly provided at one end of the connecting bar 31 away from the resistance block 30. The push assembly includes a wedge block 32, a roller 34, a vertical moving bar 35, a toggle rod 36 and a lateral moving frame 38. The wedge block 32 is provided with two fixedly connected connecting bars 31. The inclined end of the wedge block 32 is abutted and connected with a roller 34. The roller 34 is limitedly rotated and installed on the vertical moving bar 35. The vertical moving bar 35 is limitedly slidably installed in the heat treatment box 2. 2-4 linearly distributed toggle rods 36 are fixedly arranged on the vertical moving bar 35. Each set of lateral sealing strips 39 is fixedly connected to a set of lateral moving frames 38. The lateral moving frame 38 is provided with a second inclined slot 37 for accommodating the toggle rod 36. A No. 3 spring 40 is fixedly arranged at the bottom of the vertical moving bar 35. A bracket 41 is fixedly connected between the two sets of vertical moving bars 35. The bracket 41 is fixedly connected to the top sealing strip 42.

[0045] Furthermore, by arranging the resistance block 30, the connecting strip 31, the S-shaped spring piece 33, the wedge block 32, the roller 34, the vertical moving strip 35, the toggle rod 36 and the lateral moving frame 38 for use in combination, the resistance thrust of the top baffle 7 can be converted into the opposite movement of the two sets of lateral sealing strips 39 and the linear downward movement of the top sealing strip 42, so that both the lateral sealing strips 39 and the top sealing strip 42 can be stably inserted in the bite groove 5, which can not only have the effect of horizontally limiting the partition 4, but also enhance the sealing performance of the connection between the partition 4 and the heat treatment box 2.

[0046] When the present invention is used, first, the workpiece to be processed is placed on the left half of the storage plate 3, and then the rotating motor is turned on to drive the driving screw 11 to rotate. Under the screwing action of the internal and external threads, the L-shaped push plate 10 is forced to drive the driven push rod 9 to move horizontally. In this process, the right end of the L-shaped push plate 10 first acts on the arc-shaped protrusion 14, so that the arc-shaped protrusion 14 is forced to drive the limit block 15 to move downward, and the cylindrical pin 16 on the limit block 15 that moves downward acts on the first inclined groove. 17, so that the active push bar 18 is forced to squeeze the first spring 20 to move rightward, the active rack 21 on the active push bar 18 acts on the active gear 22, so that the vertical shaft 23 drives the side baffle 6 to rotate inward 90° and form a vertical angle with the storage plate 3, and when the vertical shaft 23 rotates, the driven gear 24 on it acts on the reversing rack 25, so that the reversing rack 25 is forced to move horizontally, and the driven rack 26 at the bottom of the reversing rack 25 acts on the reversing gear 27, so that the lateral rotation The shaft 28 drives the top baffle 7 to flip downward by 90°, thereby forming a rectangular closed space with the side baffle 6. At the same time, when the top baffle 7 flips downward, the squeezing force on the abutment block 30 is released, so that the connecting bar 31 drives the wedge block 32 to move toward the abutment block 30 under the elastic force of the S-shaped spring 33, so that the wedge block 32 also releases the squeezing force on the roller 34. At this time, the vertical moving bar 35 drives the toggle rod 36 to move upward under the elastic force of the No. 3 spring 40, and the toggle rod 36 The toggle rod 36 on the upper part acts on the second inclined groove 37, so that the lateral moving frame 38 is forced to drive the lateral sealing strip 39 to be pulled out from the bite groove 5, and the bracket 41 fixedly connected to the vertical moving strip 35 also moves upward together, so that the top sealing strip 42 is also pulled out from the bite groove 5; then the driven push rod 9 will push the partition 4 to move normally to the right. During the movement, a sealed space is formed between the multiple groups of side baffles 6 and the multiple groups of top baffles 7 and the partition 4 to prevent the leakage of hot air inside the heat treatment box 2;

[0047] When the two groups of partitions 4 at the far left end just move to the left and right openings of the heat treatment box 2, the above-mentioned workpiece to be processed enters the heat treatment box 2 for processing, and the workpiece after heating is moved to the right side of the heat treatment box 2 along with the storage plate 3. At the same time, the notch 29 at the bottom of the L-shaped push plate 10 is just located directly above the arc-shaped protrusion 14. The arc-shaped protrusion 14 moves upward rapidly under the elastic force of the No. 1 spring 20, so that the active push bar 18 drives the driven push frame 19 to move to the left, and the active rack 21 on the active push bar 18 acts on the active gear 22 again, so that the vertical shaft 23 drives the side baffle 6 to rotate outward 90°, and when the vertical shaft 23 rotates, the driven gear 24 thereon acts on the reversing rack 25, so that the reversing rack 25 is forced to move horizontally, and the driven rack 26 at the bottom of the reversing rack 25 acts on the reversing gear 27, so that the transverse shaft 28 drives the top baffle 7 to flip upward 90°, presenting as shown in the figure. Figure 3The state shown; at this time, the workpieces that have completed the heat treatment can be taken out normally, and a new batch of workpieces to be processed can be placed again on the right half of the storage plate 3 to prepare for the next processing; at the same time, when the top baffle 7 is flipped upward, it is squeezed on the abutment block 30, so that the connecting strip 31 squeezes the S-shaped spring piece 33 and drives the wedge block 32 to move in the direction away from the abutment block 30, so that the wedge block 32 squeezes the roller 34, so that the vertical moving strip 35 squeezes the third spring 40 and drives the toggle rod 36 to move downward, and the toggle rod 36 on the toggle rod 36 acts on the second inclined groove 37, so that the lateral moving frame 38 is forced to drive the lateral sealing strip 39 to be clamped in the bite groove 5, and the bracket 41 fixedly connected to the vertical moving strip 35 also moves downward together, so that the top sealing strip 42 is also clamped in the bite groove 5 together, thereby limiting and fixing the partition 4.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
