The utility model discloses can effectively improve the production efficiency of water tank, have advantages such as simple process, convenient operation, labour saving and time saving and low cost.
Description
Technical Field
The utility model belongs to the technical field of the flat tub of flaring device of B type, concretely relates to flat tub of for pipe gear formula flaring sword of B type.
Background
The automobile water tank core body comprises main pieces, B-type flat pipes and a plurality of radiating strips, the B-type flat pipes are arranged between the two main pieces in parallel, and the radiating strips are arranged between the B-type flat pipes. When the water tank core body is assembled, the well-arranged heat dissipation belt and the B-type flat pipe need to be flared after the main sheets at two ends are pressed in, so that the assembly clearance is further reduced, and the main sheets are prevented from shaking and being separated. The existing flaring cutter is mostly designed into an integrated cutter set according to the product specification, and flaring is finished through the front insertion movement of the cutter set. However, the quantity of the B-type flat pipes assembled on the water tanks with different specifications is different, the required number of flaring cutters is different, and therefore when the water tanks with different specifications are produced, the quantity of the blades is increased, decreased and the shape is changed, the shape changing time is longer, and the production efficiency is lower.
Disclosure of Invention
Content providing method and apparatus
The utility model discloses an overcome present one-piece type knife tackle production long problem of remodeling time and provide a flat for pipe gear formula flaring sword of B type, can effectively improve the production efficiency of water tank to simple process, low cost.
The utility model discloses a solve above-mentioned technical problem and adopt following technical scheme, a flat for pipe gear formula flaring sword of B type, its characterized in that is including pressing axle, bearing and gear sword, wherein presses axle center department and is connected with two bearings, and this bearing nestification is in the gear sword, and the prong radius and the profile of tooth of gear sword are sunken in for solve the conflict that the flat tub of main leaf hole junction of B type bottom flaring is up to standard and the tip aperture is too big arouses the flat tub of triangle district grow of B type.
Preferably, the gear cutter comprises a circular gear cutter body and gear cutter teeth uniformly distributed on the gear cutter body along the circumferential direction, a circular bulge is arranged on the inner circumferential surface of the gear cutter body along the circumferential direction and used for clamping bearings at two sides to fix the gear cutter on the pressing shaft, and a circular groove is arranged on the outer circumferential surface of the gear cutter body along the circumferential direction and used for dividing the gear cutter teeth on the gear cutter body into two rows to match with the joint of the main blade hole of the B-shaped flat tube.
Further preferably, the gear cutter tooth has the thick structure of both ends are thin in the middle of, and the free end of gear cutter tooth is round chamfer transition, and the link of gear cutter tooth is round chamfer transition with the gear cutter body.
Further preferably, the tooth space of the gear cutter is designed according to water tanks with different specifications.
Compared with the prior art, the utility model following beneficial effect has: the utility model has the advantages of being simple in structure and convenient in operation, labour saving and time saving and cost are lower, and the prong radius of pinion cutter and the sunken structure of flank profile are used for solving the contradiction that flat tub of main leaf hole junction bottom flaring of B type is up to standard and the tip aperture arouses the flat tub of trigonal grow of B type too greatly moreover, the utility model discloses the practicality is better, easily popularizes and applies, has great practical value.

Detailed Description
Combine the technical scheme of the utility model, a flat for pipe gear formula flaring sword of B type, include and press axle 1, bearing 2 and gear sword 3, wherein press axle 1 center department to be connected with two bearings 2, this bearing 2 nests in gear sword 3, and the tooth point radius and the profile of tooth of gear sword 3 are sunken for solve the conflict that the flat tub of main leaf hole junction bottom flaring of B type is up to standard and the tip aperture is too big arouses the flat tub of trigonal grow of B type.
The utility model discloses a gear sword 3 comprises a circular gear cutter body and gear sword teeth evenly distributed on the gear cutter body along the circumferential direction, a circular bulge is arranged on the inner circumferential surface of the gear cutter body along the circumferential direction and is used for clamping through bearings 2 at two sides to fix the gear sword 3 on a pressing shaft 1, a circular groove is arranged on the outer circumferential surface of the gear cutter body along the circumferential direction and is used for separating the gear sword teeth on the gear cutter body into two rows to realize the matching with the connection part of main blade holes of a B-shaped flat tube; the gear cutter tooth is of a structure with a thick middle part and thin two ends, the free end of the gear cutter tooth is in round chamfer transition, and the connecting end of the gear cutter tooth is in round chamfer transition with the gear cutter body; the tooth space of the gear cutter is designed according to water tanks with different specifications.
The utility model discloses a concrete implementation way does: the method comprises the steps of firstly placing a water tank core body, aligning the gear type flaring cutter to the center of a B-type flat pipe, moving the gear type flaring cutter inserted in front of a pressing shaft to the joint of a main blade hole, and rolling the gear type flaring cutter along the direction parallel to the main blade to finish flaring of the B-type flat pipe. For water tank cores of different specifications, flaring of the B-shaped flat pipe is completed by rotating the gear type flaring cutter at different angles.
The foregoing shows and describes the general principles of the present invention, with its principal features and advantages, and further, various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
