Description

Technical Field

[0001] The invention relates to the technical field of vacuum tempering furnaces, in particular to a hot high vacuum tempering furnace for machining cylinder liners. Background Art

[0002] Thermal high vacuum tempering furnace is a kind of equipment with high heating efficiency and low energy consumption. It is widely used in the tempering treatment of various metal materials in many industries such as machinery manufacturing and mold processing. Tempering in a vacuum state or inert gas environment can effectively prevent the surface oxidation and decarburization of the workpiece and maintain good appearance and performance. In the processing of parts such as cylinder liners, in order to increase the service life of the cylinder liners, thermal high vacuum tempering furnaces are often used to temper the cylinder liners.

[0003] When heat treating cylinder liners in some existing hot high vacuum tempering furnaces, a large number of cylinder liners are directly stacked on a loading table in the hot high vacuum tempering furnace. After the tempering treatment is completed, the loading table is pulled out and the stacked cylinder liners are taken out. However, since the surface of the cylinder liners tends to soften after absorbing a large amount of heat energy during the tempering process, the cylinder liners near the bottom of the loading table are subjected to the pressure generated by the large number of cylinder liners stacked on top of them, and are prone to slight deformation, resulting in a decrease in the yield rate of the cylinder liners in the subsequent production process. Summary of the Invention

[0004] The object of the present invention is to provide a hot high vacuum tempering furnace for machining cylinder liners, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a hot high vacuum tempering furnace for machining cylinder liners, comprising a furnace body, a furnace core located in the furnace body for tempering treatment;

[0006] Two pull-out rods, both of which are movably mounted on the outer wall of the furnace, are commonly connected to a docking plate, and baffles are mounted on both upper and lower ends of the docking plate, and each baffle is provided with a material placement mechanism;

[0007] The material placement mechanism includes a material placement platform installed on the side wall of the baffle, and two U-shaped frames are provided on the material placement platform. Slide plates are slidably installed in the two U-shaped frames. A plurality of first columns are provided on the top of one group of slide plates, and a plurality of second columns are provided on the top of the other group of slide plates. A U-shaped rotating plate is rotatably installed on the top of each of the first columns. A plurality of first toggle rods are provided on each of the U-shaped rotating plates. Additional blocks are fixedly installed on the tops of the two slide plates.

[0008] The material placement table is also provided with a mounting plate, on which a plurality of translation rods are provided, on the outer walls of the translation rods are provided a plurality of set blocks, on which a second toggle rod is provided, two extension blocks are provided at the top of the mounting plate, an adjusting screw is provided on the mounting plate, and a sleeve adapted to the adjusting screw is fixedly mounted on the baffle;

[0009] After the adjacent first toggle rod and second toggle rod are placed into the cylinder barrel of a cylinder sleeve at the same time, the adjusting screw is controlled to rotate in the sleeve to drive the mounting plate to move translationally, so that the translation rod moves translationally, and the first toggle rod and the adjacent second toggle rod are moved away from each other, which can facilitate the fixing of the cylinder sleeve on the top of the loading table for subsequent tempering processing.

[0010] The cam is secured to the rear of the second end of the U-shaped member and secured to the rear of the second end of the U-shaped member.

[0011] A translation chute is provided at the top of the material placement table, a plurality of sliding blocks are provided in the translation chute, a plug-in rod is installed on the sliding block, and a plurality of limit blocks are fixedly installed in the translation chute, and the movable space of the sliding block can be limited by the limit blocks.

[0012] The top of each of the second columns is provided with a groove that matches the width of the U-shaped rotating plate. The side walls of the grooves on the U-shaped rotating plate and the second column are provided with through holes that match the diameter of the insertion rod. The insertion rod passes through the groove on the second column and the U-shaped rotating plate located in the groove of the second column, so that the position of the U-shaped rotating plate and the first toggle rod located on the U-shaped rotating plate can be fixed.

[0013] A sliding groove is provided on the inner wall of the bottom end of the furnace, and an F-shaped support plate is slidably installed in the sliding groove. The two raised top ends of the F-shaped support plate are at the same horizontal height as the bottom end side walls of the two loading platforms, so the loading platforms can be conveniently supported by the F-shaped support plate.

[0014] A plurality of bumps are provided on the outer wall of the furnace, each of which is provided with a through hole matching the diameter of the pull rod, and the through holes on the bumps are at the same horizontal height as the pull rod, so that the pull rod can move in translation under the guidance of the through holes on the bumps.

[0015] The tops of the two raised shapes on the F-shaped support plate are both provided with holes, and insertion columns are movably inserted in the holes. The tops of the two insertion columns are respectively fixedly connected to the bottom plate of a material storage table, so that the F-shaped support plate and the two material storage tables can be installed together for use.

[0016] The upper and lower ends of the docking plate are both provided with card blocks, and the two baffles are both provided with card slots matching the card blocks on one side close to the docking plate, and the size of the card block at the bottom end of the docking plate is slightly larger than the size of the card slot, so that the docking plate and the baffle at its bottom end can be installed together with interference fit to prevent the baffle from falling.

[0017] Several of the sliding blocks are provided with insertion columns on the right side walls, and the limit blocks are provided with insertion slots that match the diameter of the insertion columns on the left side walls. After the insertion columns are inserted into the insertion slots, the sliding blocks can be fixed on the left side of the limit blocks for use.

[0018] The bottom ends of the first column and the second column are both provided with threaded grooves, and threaded columns are rotatably installed in the threaded grooves. The top ends of the slide plates are both provided with a plurality of threaded holes that match the diameters of the threaded columns. By adjusting the length of the threaded columns that are rotated and extended into the threaded holes, the heights of the first column and the second column can be adjusted according to the height of the cylinder liner for use.

[0019] The mounting plate is placed on the left side of the baffle, and the two extension blocks are respectively movably pressed against a linkage plate, and the translation rods on the mounting plate all pass through the baffle and extend to the top of the material loading platform, so that the first toggle rod and the second toggle rod can be used in conjunction with each other.

[0020] The baffle is provided with two openings with the same width and height as the U-shaped frame, and the two U-shaped frames are fixedly installed in the openings on one of the baffles, so that the additional block on the U-shaped frame can extend to the left side of the baffle and movably fit the toggle plate.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention places a plurality of cylinder liners separately on a loading platform and respectively sleeves them on the periphery of a first toggle rod, and the second toggle rod cooperates with the first toggle rod to tightly contact the inner wall of the cylinder barrel, thereby fixing the plurality of cylinder liners on the top of the loading platform at the same time. This prevents the cylinder liners from being deformed due to being stacked together during the tempering process, and can prevent adjacent cylinder liners from colliding when the loading platform is pulled out of the furnace after the tempering process is completed.

[0023] By controlling the rotation of the adjusting screw, the mounting plate is pushed to the left, and the extension block on the mounting plate will push the linkage plate to rotate upward during the translational movement. At this time, the second rotating shaft fixedly connected to the linkage plate rotates and cooperates with the first gear ring through the second gear ring to reverse the first rotating shaft, so that the toggle plate located on the first rotating shaft pushes the additional block and the slide plate to move in the opposite direction of the translation rod, that is, the first toggle rod and the second toggle rod move in opposite directions and fit against the inner wall of the cylinder liner to fix the position of the cylinder liner to be processed.

[0024] By moving the sliding block to the right in the translational slide groove, the insertion rod is inserted into the through hole on the U-shaped rotating plate and the second column groove, which can limit the U-shaped rotating plate from continuing to rotate around the first column. When taking the cylinder sleeve on the loading table, the sliding block can be pushed to the left, and at the same time, multiple insertion rods are disconnected from the U-shaped rotating plate and the second column, which makes it convenient to quickly push the U-shaped rotating plate to rotate upward and facilitate the taking of the cylinder sleeve after the tempering process.

After the insertion rod 12 is inserted into the through holes on the U-shaped rotating plate 16 and the grooves of the second uprights 17, the U-shaped rotating plate 16 can be restricted from continuing to rotate around the first upright 15. A plurality of first toggle rods 18 are movably installed on the U-shaped rotating plate 16, which are inserted into the cylinder of the cylinder liner through the first toggle rods 18, so as to facilitate the later limiting processing of the cylinder liner.

[0041] The mounting plate 20 is located on the left side of the baffle 6. A plurality of translation rods 21 are fixedly mounted on the mounting plate 20.

The sleeve 25 is fixedly mounted on the left side wall of the baffle 6, and a thread groove matching the outer thread of the adjusting screw 24 is provided on the inner wall of the sleeve 25. By controlling the rotation of the adjusting screw 24 The movable plate 20 and the translation rod 21 are conveniently fixed in different positions for use. Two first U-shaped blocks 26 are fixedly installed on the left side wall of the baffle 6. The two first U-shaped blocks 26 are rotatably mounted with a first rotating shaft 27. The outer wall of the first rotating shaft 27 is fixedly mounted with a toggle plate 28. The top of the slide plate 14 is fixedly mounted with an additional block 19. The toggle plates 28 are movably fitted on the additional block 19, and the side wall of the toggle plate 28 close to the additional block 19 is an arc surface to prevent the toggle plate 28 from getting stuck when pushing the additional block 19 to move. A first gear ring 29 is fixedly mounted on the outer wall of the first rotating shaft 27. The bottom end of the first gear ring 29 is movably fitted with a second gear ring 32. The first gear ring 29 The outer wall of the second gear ring 32 is provided with a plurality of teeth that can mesh with each other, so as to drive the second gear ring 32 to rotate during the rotation of the first gear ring 29. The second gear ring 32 is fixedly mounted on the outer wall of the second rotating shaft 31. A second U-shaped block 30 is rotatably mounted on the outer wall of the second rotating shaft 31, and the second U-shaped block 30 is fixedly mounted on the left side wall of the baffle 6. A linkage plate 33 is fixedly mounted on the outer wall of the second rotating shaft 31, and the linkage plate 33 is movably attached to the top of the extension block 36.

The position of the mounting plate 20 is adjusted by movement. The extension block 36 on the mounting plate 20 pushes the linkage plate 33 to rotate upward during the translation movement. At this time, the second rotating shaft 31 fixedly connected to the linkage plate 33 rotates and cooperates with the first gear ring 29 through the second gear ring 32 to reverse the first rotating shaft 27, so that the toggle plate 28 located on the first rotating shaft 27 pushes the additional block 19 and the slide plate 14 to move in the opposite direction of the translation rod 21, that is, the first toggle rod 18 and the second toggle rod 23 move in opposite directions and fit the inner wall of the cylinder liner, which is convenient for fixing the position of the cylinder liner and avoiding collision between adjacent cylinder liners when the cylinder liner is transported into the furnace 2 for tempering treatment, resulting in deformation and damage.

At this time, the first toggle rod 18 located on the U-shaped rotating plate 16 will synchronously extend into the cylinder barrel of a cylinder sleeve, that is, a first toggle rod 18 and a second toggle rod 23 are placed in the cylinder barrel of each cylinder sleeve, controlling the sliding block 11 to translate in the translation groove 9, driving the insertion rod 12 to translate and pass through the second column 17 and the U-shaped rotating plate 16, limiting the U-shaped rotating plate 16 from continuing to rotate. At this time, the limit block 10 and the sliding block 11 are connected. By inserting the insertion column into the insertion slot and connecting it into a whole, the position of the insertion rod 12 is fixed, and the adjusting screw 24 can be controlled to rotate and extend into the sleeve 25. The adjusting screw 24 pushes the mounting plate 20 to move to the left, and the extension block 36 on the mounting plate 20 will push the linkage plate 33 to rotate upward during the translation movement. At this time, the second rotating shaft 31 fixedly connected to the linkage plate 33 rotates and cooperates with the first gear ring 29 through the second gear ring 32 to reverse the first rotating shaft 27, so that the toggle plate 28 located on the first rotating shaft 27 pushes the additional block 19 and the slide plate 14 to move in the opposite direction of the translation rod 21, that is, the first toggle rod 18 and the second toggle rod 23 move in opposite directions and fit the inner wall of the cylinder sleeve, fixing the position of the cylinder sleeve, and the material loading table 8 can be pushed into the interior of the furnace 2 for tempering processing.
