Description

Technical Field

[0001] The utility model relates to the technical field of processing processing waste chips, in particular to a processing waste chip briquetting tool. Background Art

[0002] Machining waste is the processing waste generated by the machining center. These processing wastes are first filtered out by coolant, then pressed into blocks, and then re-entered into the production of workpieces as recycled production materials. This method not only improves the utilization rate of materials, but also avoids pollution to the environment.

[0003] At present, when processing waste chips into briquette, there is a problem of difficulty in discharging the briquette-formed blocks. The current method is to first fill the waste chips into the mold cavity, and then form them by downward extrusion. After forming, the lower mold drives the block to move downward, and then the block is ejected from the lower mold by a pushing device. This method increases energy consumption due to the use of multiple hydraulic cylinders. Utility Model Content

[0004] The utility model provides a tool for pressing briquetting waste chips to solve the above-mentioned deficiencies in the prior art, facilitates the automatic discharge operation of block objects during the demoulding process, and has strong practicality.

[0005] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0006] A tool for processing waste chip briquetting, including a middle mold, a middle mold cavity is formed through the middle mold from top to bottom, a lower pressure oil cylinder is provided at the upper end of the middle mold, a lower pressure plate is provided at the lower end of the lower pressure oil cylinder, side plates are respectively provided on both sides of the middle mold, the side plates are in an inverted convex structure, a middle vertical hole is opened on the side plates, limiting holes are provided on both sides of the middle vertical hole, the lower ends of the limiting holes are open, a bottom plate is provided at the lower ends of the side plates, an upper oil cylinder is installed on the bottom plate, an articulated seat is provided at the upper end of the upper oil cylinder, a rotating rod is provided at the upper end of the articulated seat for rotation, a rotating seat is provided on the rotating rod, a lower template is provided at the upper end of the rotating seat, lower convex plates are provided on both sides of the lower template, a limiting rod is provided at the lower end of the lower convex plate, the limiting rod is passed through the limiting hole, and the horizontality of the lower template can be ensured by the cooperation of the two, thereby avoiding affecting the pressing molding due to the tilted state of the lower template during the molding process. The outer end of the rotating rod is provided on the gear, and the rotating rod passes through the middle vertical hole. A rack is provided at the lower end of the side plate. When the gear is engaged with the rack, the limit rod moves out of the limit hole. Through the setting of the rack and the gear, the lower template moves downward, and when the gear is engaged with the rack, one end of the lower template can be rotated, so that the block on it can be naturally discharged from the lower template.

[0007] Furthermore, a protective ring is provided at the upper end of the middle mold, and a feeding concave is provided on one side of the protective ring. The protective ring can prevent waste chips from falling, and the feeding concave facilitates the feeding operation of the waste chips.

[0008] Furthermore, the feeding concave is arranged at an angle, and the inner end thereof extends downward at an angle. The inclined feeding concave facilitates throwing waste chips into the middle mold cavity.

[0009] Furthermore, a convex block is provided on the upper wall of the lower mold plate, and the convex block passes through the lower end of the middle mold cavity. The provision of the convex block further ensures the horizontality of the lower mold plate to ensure the normal progress of the press molding.

[0010] The advantages of the above technical solution are:

[0011] The utility model is convenient for pressing and forming processing waste chips, and can also perform discharge operation during the demoulding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0014] Figure 2 Shows a three-dimensional structure of one embodiment Figure 2 . DETAILED DESCRIPTION

[0015] like Figure 1~Figure 2 As shown, a tool for briquetting waste chips includes a center die 1 having a center die cavity formed therethrough from top to bottom. A protective ring 10 is provided at the upper end of the center die 1. A feed recess 11 is provided on one side of the protective ring 10. Feed recess 11 is tilted, with its inner end extending downward. A downward pressure cylinder 20 is provided at the upper end of the center die 1, and a downward pressure plate 2 is provided at the lower end of the downward pressure cylinder 20.

[0016] A side plate 3 is provided on both sides of the middle mold 1. The side plate 3 has an inverted convex structure. A middle vertical hole 31 is opened on the side plate 3. Limit holes 30 are provided on both sides of the middle vertical hole 31. The lower end of the limit hole 30 is open. A bottom plate 44 is provided at the lower end of the side plate 3. An upper oil cylinder 45 is installed on the bottom plate 44. The upper end of the upper oil cylinder 45 is provided with a hinged seat 46. A rotating rod 41 is rotatably provided at the upper end of the hinged seat 46. A rotating seat 40 is provided on the rotating rod 41. A lower mold plate 4 is provided at the upper end of the rotating seat 40. A protrusion is provided on the upper wall of the lower mold plate 4. The protrusion passes through the lower end of the middle mold cavity. Lower convex plates 47 are provided on both sides of the lower template 4, and a limiting rod 48 is provided at the lower end of the lower convex plate 47. The limiting rod 48 passes through the limiting hole 30. The outer end of the rotating rod 41 is provided on the gear 42. The rotating rod 41 passes through the middle vertical hole 31. A rack 43 is provided at the lower end of the side plate 3. When the gear 42 is engaged with the rack 43, the limiting rod 48 moves out of the limiting hole 30.

[0017] During operation of this embodiment, waste chips are first loaded into the middle mold cavity through the feeding concave part 11, and when transferring the filling, the upper cylinder 45 is required to make the protrusion pass through the lower end of the middle mold cavity. When a certain amount is filled, the lower pressure cylinder 20 is started to drive the lower pressure plate 2 to move downward, and the lower pressure plate 2 acts on the loose waste chips to press them into a pancake-shaped structure. Then the lower pressure plate 2 is removed from the middle mold cavity, and the material is fed again and squeezed again. This reciprocating process is repeated until the waste chips are in a block-shaped structure. Then the upper oil cylinder 45 is started, and the lower template 4 moves downward under the drive of the upper oil cylinder 45. During the movement, the limit rod 48 moves in the limit hole 30 until the limit rod 48 moves out of the limit hole 30. At the same time, the gear 42 and the rack 43, as the two are combined, will cause one end of the lower template 4 to rotate downward, and eventually make it tilted. Then the block will move downward from the protrusion, and then the lower template 4 returns to its initial position. In the process of demolding, it is necessary to first separate the protrusion and the block through the downward movement of the lower template 4, and then act on the block through the lower pressure plate 2, so that the block is removed from the middle mold cavity and the action is canceled and returns to its initial position. This operation method facilitates the natural falling of the block.

[0018] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Therefore, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
