Abstract

A mold for inner pipe of car muffler is characterized by comprising an expansion mold, a slanting slider [2], an upper mold [3] and a lower mold [5]; the expansion mold is composed of a left molding block [1] and a right molding block [1], polyurethane rubber [4] for molding is installed between the molding blocks [1]; the upper mold [3] is provided with a mandrel and is fixed with the slanting slider [2] which is used for matching mold; the slanting slider [2] is sleeved outside the molding blocks [1] of the expansion mold. The mold for inner pipe of car muffler combines three working procedures, consisting of expanding the middle part, expanding the round hole and expanding the V-shaped hole, into one working procedure, such that the structure is simple and the use of expensive special devices for manufacture can be avoided, the problem of unstable position size of product in molding process is solved, the product quality is improved, the waste of labor and material caused by multiple working procedures is reduced, and the production efficiency is improved.

Description

The mould of pipe in a kind of automotive muffler
Technical field
The utility model belongs to the automobile component manufacture field, particularly the processing and forming of automotive muffler.
Background technology
The automotive muffler inner tube structure, both sides port necking down, middle bulging thin-walled hollow normally adopt Sheet Metal Forming Technology to be shaped, and adopt the method for welding to make again.In automotive muffler in the processing technology of pipe, what traditional production Sheet Metal Forming Technology adopted is single operation method, part in process of production, cause accumulated error to strengthen through multiple operation (blanking → volume U-shaped → volume circle → shaping → welding → centre → expansion round mouth → expansion V-shaped part → punching of expanding), form product space size instability, easy to crack, the distortion of part in the bulging, product quality is very unstable.At this situation, the present invention proposes a kind of new technical scheme, causes the unstable product quality problem to solve product because of multiple operation.
Summary of the invention
The purpose of this utility model provides the mould of pipe in a kind of automotive muffler.
Mould described in the utility model (as shown in Figure 1) is made up of bulging die, angled-lift splits [2], patrix [3], counterdie [5].Two type pieces [1] about bulging die is divided into are equipped with the polyurethane rubber [4] that moulding is used in the middle of the type piece [1], and patrix [3] is equipped with plug and the angled-lift splits [2] used with matched moulds is fixed together, and angled-lift splits [2] is enclosed within the outside of bulging model block [1].During work, patrix [3] is descending to be made the bulging die matched moulds and continues descendingly by the compression of the plug on the patrix [3] polyurethane rubber [4] by angled-lift splits [2], makes product parts produce plastic deformation through the transversely deforming of polyurethane rubber [4] and directly causes shaping; The angled-lift splits of using when the up matched moulds of patrix [3] [2] is when leaving counterdie, and the bulging model block is separated under the effect of the branch mould spring force that is installed in counterdie to the left and right, and just can take out the good workpiece that is shaped this moment, finishes the production process of a subjob.
Patrix of the present utility model [3], counterdie [5], polyurethane rubber [4] and bulging model block have constituted the size of workpiece top, centre and afterbody.
With the moulding process of pipe in the automotive muffler, focus on the bulging operation, the utility model centre → expansion round mouth → three operations of expansion V-shaped part that will expand are merged into an operation, and are simple in structure, also avoid adopting expensive special equipment to produce.By this project implementation, solve product product space size instability problem in forming process, improved product quality, reduced the waste that causes human and material resources because of multiple operation is suffered, improved production efficiency.
Description of drawings
Fig. 1 is a system architecture schematic diagram of the present utility model.1 is the bulging model block, and 2 is angled-lift splits, and 3 is patrix, and 4 is polyurethane rubber, and 5 is counterdie.
Fig. 2 is a product schematic diagram of the present utility model.
Fig. 3 is the concrete dimensional drawing of an embodiment of the utility model.
The specific embodiment
The utility model will be described further by following examples.
Embodiment.
As shown in Figure 1, the mould of present embodiment is made up of bulging die, angled-lift splits 2, patrix 3, counterdie 5.The polyurethane rubber 4 that moulding is used is installed in the middle of two type pieces 1 about bulging die is divided into, type piece 1, and patrix 3 is equipped with plug and is fixed together with angled-lift splits 2 that matched moulds is used.During work, patrix 3 is descending to be made the bulging die matched moulds and continues descendingly by the compression of the plug on the patrix 3 polyurethane rubber 4 by angled-lift splits 2, makes product parts produce plastic deformation through the transversely deforming of polyurethane rubber 4 and directly causes shaping; When the angled-lift splits of using when patrix 3 up matched moulds 2 left counterdie, the bulging model block was separated under the effect of the branch mould spring force that is installed in counterdie to the left and right, and just can take out the good workpiece that is shaped this moment, finished the production process of a subjob.
Present embodiment is to finish on 160 tons hydraulic press.
The mould key dimension (cm) of present embodiment is: profile 500*350*425, and angled-lift splits is high by 200, patrix 36, the bulging model block is wide by 150, counterdie 40.6.
