Description

Coreless stamping tool bit

Technical Field

The utility model relates to an automobile condenser and evaporimeter technical field, concretely relates to carry out stamping tooling's punching press tool bit to pressure manifold.

Background

An important part in the condenser and the evaporator is a collecting pipe, and a partition plate groove is often required to be formed in the collecting pipe for installing a partition plate. In the prior art, when stamping is performed on a collecting pipe, a cored stamping head often forms a large contact area when in stamping contact with the collecting pipe, so that the edge of a separator groove formed by stamping on the collecting pipe is collapsed and deformed, or a flanging is formed to a certain extent to deform, the appearance of the separator groove formed by stamping is not accurate, and the processing progress and the processing precision of processing the separator groove on the collecting pipe are severely restricted.

In the prior art, there is also a method for machining a partition groove, in which a cutting tool bit is used to cut on a collecting pipe, and when the cutting tool bit is used to work, the cutting tool bit and the collecting pipe need to be moved relatively to process the partition groove, so that the accuracy of the moving position and the distance cannot be guaranteed no matter the cutting tool bit is moved or the collecting pipe is moved, and the position and the size of the partition groove machined on the collecting pipe are not accurate, which seriously affects the quality of the partition groove machined on the collecting pipe.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model discloses to prior art's not enough, release a centreless punching press tool bit for the baffle groove border that the punching press tool bit punching press among the solution prior art formed sinks or turn-ups technical defect, and cuts the problem that baffle trench position, size are all inaccurate inefficiency.

Second, the concrete technical scheme

The realization principle is as follows: the utility model provides a centreless punching press tool bit, including vertical just be the mounting panel of rectangle plate-like structure, this mounting panel upper portion is opened there is the mounting hole, this mounting panel lower extreme fixedly connected with plate-like structure and with the coplanar punching press head of mounting panel, this punching press head including the punching press pointed end with be located the punching press limit of the most advanced both sides of this punching press, this punching press is pointed to be located the bottom of punching press head and this punching press pointed end are located on the central line of mounting panel, two the punching press limit is established respectively the punching press is pointed to with between two sides of mounting panel.

The working principle is as follows: and the coreless stamping tool bit is arranged on the stamping die by means of an external stamping die, the collecting pipe is arranged on the stamping die and fixed below the stamping head, then the pipe wall of the collecting pipe is stamped, and the processing of stamping the pipe wall of the collecting pipe to form the partition plate groove is finished at the moment.

Because the punching press head is the punching press head of coreless plate-type structure, when this punching press head carries out the punching press to the pressure manifold, this punching press head is less with the area of pressure manifold punching press contact, can not cause the interference to the baffle groove border that the punching press formed under great punching press pressure effect, consequently avoided the baffle groove border that the punching press formed among the prior art to sink, turn-ups phenomenon, improved machining precision and efficiency to the baffle groove.

Preferably, the method comprises the following steps: and the two stamping edges are smooth arc edges arched upwards. Will the punching press limit is established to smooth arc limit, and its effect can be so that the baffle groove border that the punching press formed is more natural, does not have the burr, and the arc the punching press limit can guarantee further that the baffle groove border that the punching press formed can not sink, the turn-ups, moreover the arc limit with the most advanced mutually support of punching press, can make more smoothly the most advanced punching press cuts into on the pressure manifold pipe wall, has guaranteed that the baffle groove that the punching press formed is softer, accurate.

Preferably, the method comprises the following steps: the mounting plate and the stamping head are of a fusion casting forming integrated structure. Will mounting panel, punching press head establish structure as an organic whole, and its main objective has guaranteed mounting panel, punching press head form a whole, have promoted mounting panel, punching press head are as a holistic bulk strength, prevent the deformation phenomenon that the punching press head appears in punching press working process, thereby improved mounting panel, punching press head's life has reduced the number of times of changing, has improved suitable efficiency.

Preferably, the method comprises the following steps: stamping die with installation centreless stamping tool bit, this stamping die including the horizontally upper die base, locate this upper die base lower extreme and horizontally upper padding plate, locate this upper padding plate below and with the die holder that the upper die base is relative, locate the lower bolster of this die holder upper end, the upper die base drives directional removal from top to bottom and locking at any time on the upper padding plate, the upper padding plate sub-unit connection has two rows the punching press head, the equipartition interval of every row of this punching press head arranges, and every row of this punching press head below all corresponds and is equipped with the horizontally standing groove, and two these standing grooves are all seted up the lower bolster top. The stamping die is matched with the stamping head to stamp an ideal partition plate groove, and the edge of the partition plate groove is not collapsed or flanged.

Preferably, the method comprises the following steps: two rows of mounting grooves with downward openings are formed in the lower portion of the upper padding plate, the mounting grooves in each row are distributed at equal intervals, the stamping tool bits in each row are correspondingly mounted in the mounting grooves in a uniform mode, each row of the mounting grooves are internally provided with a horizontal detachable type insertion rod in a penetrating mode, and the insertion rods penetrate through the rows of the mounting holes in the stamping tool bits.
