Abstract
Description
Technical Field
[0001] The utility model belongs to the field of casting surplus material cutting devices, in particular to a bucket tooth casting runner cutting device. Background Art
[0002] Bucket teeth of construction machinery, such as excavators and bulldozers, are usually made by casting process. In order to improve casting efficiency and reduce the number of casting molds, Figure 1 As shown in the figure above, there are two cavities connected on both sides of the pouring channel of the casting mold, so two bucket teeth can be formed in one pouring, such as Figure 1 As shown in the figure below, the middle of the two bucket teeth are connected together by the metal residue formed in the runner. The side where the bucket teeth are connected to the residue is an inclined surface. Due to the special structure, in the existing production, workers usually use a manual grinder to cut off the residue after casting. The cutting efficiency is low, and the bucket teeth that have just been demolded still have a high temperature and cannot be cut immediately. It takes a long time to cool down before cutting, which prolongs the production cycle of the bucket teeth. Utility Model Content
[0003] In order to solve the deficiencies in the prior art, the utility model provides a bucket tooth casting runner cutting device, which has high cutting efficiency and is not affected by the high temperature of the bucket tooth, thus helping to shorten the production cycle of the bucket tooth.
[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:
[0005] A bucket tooth casting runner cutting device comprises a conveying component and a cutting assembly.
[0006] The conveying component is arranged to move in a straight line direction, and a pair of supporting members are arranged on its top surface perpendicular to the moving direction, respectively used to connect the mounting holes at the bottom of two bucket teeth, and the outer contour of the supporting members matches the mounting holes of the bucket teeth.
[0007] The cutting assembly is arranged above the conveying component, and includes two saw discs arranged in a V-shaped structure, which are used to cut off the connection between the residual material of the runner and the two bucket teeth. The saw discs are parallel to the corresponding side surfaces of the bucket teeth. Both sides of the cutting assembly are provided with limit plates parallel to the top surface of the conveying component. The limit plates are located above the bucket teeth connected to the support.
[0008] The beneficial effect of the utility model is that the device can simultaneously cut off the connection between two bucket teeth and the runner residue, which has higher efficiency, and because there is no need to make close contact with the bucket teeth, the bucket teeth can be cut off after demoulding, which reduces the cooling waiting link and effectively shortens the production cycle of the bucket teeth.

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0017] like Figures 2 to 5 As shown, a bucket tooth casting runner cutting device includes: a conveying component 1 and a cutting component 2.
[0018] The working part of the conveying component 1 is arranged to move in a straight line, and a pair of support members 11 are arranged on its top surface perpendicular to the moving direction, respectively used to connect the mounting holes at the bottom of two bucket teeth, and the outer contour of the support member 11 matches the mounting holes of the bucket teeth.
[0019] The cutting assembly 2 is arranged above the conveying component 1, and includes two saw discs 21 arranged in a V-shaped structure, which are used to cut off the connection between the runner residue and the two bucket teeth. The saw discs 21 are parallel to the corresponding bucket tooth sides. Both sides of the cutting assembly 2 are provided with limit plates 3 parallel to the top surface of the conveying component 1. The limit plates 3 are located above the bucket teeth connected to the support 11, and are used to prevent the bucket teeth from jumping upward during cutting, thereby preventing the bucket teeth from falling off the support 11.
[0020] When cutting, use clamping tools such as pliers to place the demolded bucket teeth on the conveying component 1, and clamp the bottom grooves of the two bucket teeth in two connecting supports 11 arranged in pairs; the conveying component 1 transfers the bucket teeth to the bottom of the cutting component 2 and the limit plate 3, and the bucket teeth slowly pass through the cutting component 2, and the saw disk 21 cuts the remaining material of the runner. When the remaining material of the runner completely passes under the saw disk 21, the cutting of the remaining material of the runner is completed. Compared with manual cutting, the device can cut the connection between the two bucket teeth and the remaining material of the runner at the same time, which has higher efficiency. In addition, because there is no need to contact the bucket teeth at close range, the bucket teeth can be cut after demolding, which reduces the cooling waiting link and effectively shortens the production cycle of the bucket teeth.
[0021] Preferably, Figure 2 , Figure 4 As shown, the conveying component 1 is an annular conveying structure, specifically a transmission belt or a transmission chain structure, and a plurality of support members 11 are arranged along the annular structure array of the conveying component 1. The cutting assembly 2 is located in the middle of the upper section of the conveying component 1. At this time, the upper section of the conveying component 1 is the working part of the conveying component 1, and it is arranged to move along a straight line. In this way, the support member 11 can be recycled, and compared with the reciprocating conveying component 1, the waiting time is reduced. Moreover, the annular conveying structure can be set so that after the cutting is completed, the support member 11 automatically throws out the bucket teeth in the process of moving downward, or the weight of the bucket teeth is used to automatically separate it from the support member 11.
[0022] Further preferably, Figure 2 , Figure 4 As shown, a support plate 12 is provided at a position on the bottom surface of the conveying component 1 corresponding to the bottom of the cutting component 2. It can be understood that a support plate 12 is provided below the working part of the conveying component 1 to prevent the conveying component 1 from deforming downward under the cutting force of the saw disk 21, thereby improving the stability when cutting the runner residue.
[0023] As a driving solution, the two saw discs 21 are driven by independent motors.
[0024] As a preferred solution, Figure 5As shown, the cutting assembly 2 includes a mounting box 22, and the main shafts of the two saw discs 21 are passed through the opposite side walls of the mounting box 22. The main shafts of the saw discs 21 are coaxially provided with driven bevel gears 23, and the driven bevel gears 23 are located in the mounting box 22. A driving motor 24 is provided on the top of the mounting box 22, and the main shaft of the driving motor 24 is provided with an active bevel gear 25. The active bevel gear 25 is meshed with the two driven bevel gears 23 at the same time. The saw teeth of the two saw discs 21 face opposite directions. With this structural design, one driving motor 24 can be used to drive the two saw discs 21 to rotate at the same time, and the structure is more compact and convenient to arrange and install. The opposite directions of rotation will form two opposite forces on the bucket teeth, so that the forces generated by the saw disc 21 on the bucket teeth offset each other, thereby further preventing the bucket teeth from jumping and avoiding the bucket teeth from separating from the support 11.
[0025] Further preferably, the installation box 22 is provided with a detachable cover to enhance the dustproof protection, and the drive motor 24 is arranged on the top surface of the cover. When the cover is removed, the drive motor 24 and the active bevel gear 25 can be taken away at the same time, which is convenient for disassembly and assembly.
[0026] Preferably, Figures 2 to 4 As shown, a support frame 4 is provided above the conveying component 1, and a lifting device 5 is provided on the top horizontal plate thereof, and a movable rod of the lifting device 5 is vertically directed toward the top surface of the conveying component 1, and the cutting assembly 2 is connected to the lower end of the movable rod of the lifting device 5, so that the height of the cutting assembly 2 can be controlled by the lifting device 5. In order to improve the stability of the cutting assembly 2, a plurality of guide rods passing through the top of the support frame 4 can be provided on the cutting assembly 2.
[0027] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
