Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of grinding wheel processing equipment, and more specifically, it relates to a furnace feeding device for grinding wheel sintering. Background Technology
[0002] Sintering is required during the manufacturing process of grinding wheels. The dried grinding wheel blank needs to be sintered at high temperature to fully melt the binder and firmly bond it with the abrasive. The sintering temperature is usually around 1200-1300℃, and the sintering time depends on the size of the grinding wheel and specific process requirements, generally requiring several hours.
[0003] During sintering, grinding wheels are typically stacked sequentially on a grinding wheel rack and then placed in the sintering furnace. After sintering, they need to be removed. Current manual forklifts are single-push-out forklifts, which, in practical use, cannot be made too long for the sake of turning and moving flexibility, and their length is fixed and not extendable. Therefore, it is not convenient to reach too deep into the sintering furnace to remove the grinding wheel stacking rack.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a furnace feeding device for grinding wheel sintering, in order to achieve a more practical purpose. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a furnace insertion and feeding device for grinding wheel sintering, which solves the problem that manual forklifts in the prior art cannot easily extend too deep into the sintering furnace to remove the grinding wheel stacking rack.
[0006] The purpose and effect of this utility model's furnace feeding device for grinding wheel sintering are achieved by the following specific technical means:

[0035] Example:
[0036] As attached Figure 1 To be continued Figure 7 As shown:
[0037] This utility model provides a furnace feeding device for grinding wheel sintering, comprising:
[0038] The base frame 10 and the support frame 11 are fixedly connected to the base frame 10. A carrier frame 14 is vertically slidably connected to the support frame 11. A carrier plate 21 is fixedly connected to the front side of the carrier frame 14. An extension frame 16 is movably connected to the carrier plate 21 in the front-back direction. Multiple casters 200 are installed at the bottom of the base frame 10.
[0039] Hydraulic jack 12 is installed on the base frame 10 and can drive the carrier frame 14 to move up and down;
[0040] Telescopic mechanism 20 is mounted on carrier plate 21 and can drive extension frame 16 to move back and forth.
[0041] Counterweight mechanism 17 is mounted on base frame 10.
[0042] In this embodiment, by providing a retractable extension frame 16 on the carrier plate 21, the distance of the grinding wheel stacking frame can be extended, making the feeding device more adaptable. A hydraulic jack 12 is used to drive the extension frame 16 to move up and down, and a counterweight mechanism is used to adjust the overall center of gravity of the equipment when the extension frame 16 is extended, preventing tipping. Furthermore, while ensuring material feeding, the extension frame 16 has a small volume when retracted, facilitating movement and turning within the working space.
[0043] The upper end of the drive rod 121 of the hydraulic jack 12 is rotatably connected to a movable pulley 13. The carrier frame 14 is connected to one end of the chain 15, and the other end of the chain 15 is wrapped around the outer circumference of the movable pulley 13 and fixedly connected to the support frame 11.
[0044] When the hydraulic jack 12 drives the drive rod 121 to move up and down, the movable pulley 13 moves up and down with the drive rod 121, thereby driving the carrier 14 connected to the movable end of the chain 15 to move up and down.
[0045] The extension frame 16 has two sets of front rollers 161 rotatably connected to the front side and two sets of rear rollers 162 rotatably connected to the rear side. The front rollers 161 are rotatably connected to the upper surface of the carrier plate 21, and the rear rollers 162 are rotatably connected to the lower surface of the carrier plate 21.
[0046] The front roller 161 is on the upper surface of the carrier plate 21, and the rear roller 162 is on the lower surface of the carrier plate 21. When the front of the extension frame 16 carries materials, the front of the extension frame 16 is subjected to downward pressure. The front roller 161 and the rear roller 162 abut against the upper and lower surfaces of the carrier plate 21, respectively, thereby ensuring that the extension frame 16 can move back and forth along the carrier plate 21 while bearing the weight.
[0047] The telescopic mechanism 20 includes two parallel transmission rods 201. Each transmission rod 201 is provided with a lead screw part 2011. The threads of the two lead screw parts 2011 are opposite in direction, and the lead screw parts 2011 are threadedly connected to corresponding lead screw nuts 202.
[0048] A gear 203 is fixedly connected to the transmission rod 201, and the two gears 203 mesh with each other. One of the transmission rods 201 is fixedly connected to the remote rod 204.
[0049] The extension frame 16 is provided with two slots 163 and two through holes 164. The lead screw nut 202 is fixedly connected in the through hole 164, and the slots 163 are slidably connected to the extension frame 16.
[0050] When the remote lever 204 is rocked, the corresponding transmission rod 201 rotates, and the other transmission rod 201 rotates in opposite directions under the meshing action of the gear 203, thereby driving the two lead screw nuts 202 to move back and forth synchronously, thus driving the extension frame 16 to move back and forth.
[0051] It also includes a counterweight mechanism 17 disposed on both sides of the base frame 10. The counterweight mechanism 17 includes a rod 171 rotatably connected to the base frame 10, an insert rod 172 passing through and slidably connected to the rod 171, a column 177 vertically fixedly connected to the outer end of the rod 171, a counterweight block 173 sleeved on the column 177, a spring 174 sleeved on the outer periphery of the insert rod 172, and a pull plate 175 fixedly connected to the outer end of the insert rod 172. The inner end of the rod 171 is fixedly connected to a rotating shaft 176, which is rotatably connected to the base frame 10. One end of the spring 174 is fixedly connected to the rod 171, and the other end of the spring 174 is fixedly connected to the upper part of the insert rod 172.
[0052] Multiple insertion holes 300 are arranged in a circular array along the axis of the pivot 176 on the base frame 10, and the insertion holes 300 are arranged corresponding to the insertion rods 172.
[0053] In use, multiple counterweights 173 are stacked on the column 177 for counterweighting, and the insertion rod 172 is pulled up while the rods 171 on both sides are rotated to adjust the center of gravity of the equipment. The insertion rod 172 springs back into the insertion hole 300 under the action of the spring to fix the position of the rod 171.
[0054] Two handles 18 are fixedly connected to the support frame 11.
[0055] In actual use, the handle 18 can be fitted with a rubber sleeve to facilitate the operator in moving the equipment.
[0056] A baffle 19 is provided on the side of the handle 18 near the extension frame 16, and a heat insulation layer is provided on the inner side of the baffle 19. The heat insulation layer can be made of rock wool to prevent the user's hands from being scorched by high temperatures.
[0057] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
