Description

Technical Field

[0001] The utility model belongs to the technical field of fastener processing, and particularly relates to a forming die for the processing of bucket-shaped bolts. Background Technique

[0002] For the processing of the bolt head part, it is formed by the method of stamping after heating. Since the raw material of the bolt is a cylindrical material, the existing forming die has a cylindrical forming cavity, and a flaring part for forming the bolt head is arranged at the top of the forming cavity, and a plugging structure for supporting the bolt structure is arranged at the bottom of the forming cavity.

[0003] When the bolt raw material is in a red-hot state during stamping, slag may fall during stamping and may accumulate in the forming cavity. In the existing forming die, it is not conducive to the discharge of slag, which may affect the subsequent forming effect and thus the product quality.

[0004] Therefore, designing a forming die that is conducive to slag discharge and cleaning is a problem that needs to be solved by the workers in this field. Content of the Utility Model

[0005] The purpose of the utility model is to provide a forming die for the processing of bucket-shaped bolts. By designing a new die structure and arranging a slidable support seat, after the support seat is in place, the cushion seat is concentrically arranged directly below the cylindrical cavity, and a complete forming cavity can be formed for the stable stamping forming of the bolt. After the support seat is removed, the slag inside the forming cavity can be quickly discharged, ensuring the forming effect and quality of the bolt.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a forming die for the processing of bucket-shaped bolts, including a workbench, an oil cylinder and a support seat. A forming die base is fixed on the top of the workbench;

[0008] A forming cavity is arranged at the center of the forming die base. The forming cavity includes a cylindrical cavity and a conical bucket cavity. A lower opening is arranged at the center of the bottom of the forming die base;

[0009] An upper opening connected to the forming cavity is arranged at the rear side of the forming die base. The upper opening occupies half of the cylindrical cavity, and the upper opening is communicated with the lower opening;

[0010] The thickness of the support seat is the same as the height of the lower opening. The support seat is slidably arranged on the upper surface of the workbench. A sealing plate body is fixed on the top of the support seat. A semi-circular arc-shaped groove is arranged inside the sealing plate body, and a cylindrical cushion seat is fixed inside the arc-shaped groove;

[0011] On both sides of the top of the support base, side plates are fixed. At both ends between the two side plates, a front end plate and a rear end plate are respectively fixed. The oil cylinder is fixed on the top of the workbench and is connected to the rear side of the support base.

[0012] When the oil cylinder extends, the rear end plate fits against the rear side surface of the forming die base. The sealing plate body slides into the upper opening. The arc-shaped groove is concentric with the cylindrical cavity, and the cushion base is concentrically arranged directly below the cylindrical cavity.

[0013] Furthermore, a slag scraping plate is fixed on the front side surface of the support base. The slag scraping plate is an arc-shaped plate and its bottom edge slides along the upper surface of the workbench.

[0014] Furthermore, a mounting seat is fixed at the bottom of the sealing plate body. The mounting seat is fixed to the top of the support base through fasteners, and the bottom surface of the cushion base fits against the top surface of the mounting seat.

[0015] Furthermore, a preset opening is provided on the sealing plate body. A fastening bolt is provided on the circumferential side surface of the cushion base. The cushion base is fixed to the sealing plate body through the fastening bolt and the preset opening.

[0016] Furthermore, when the oil cylinder contracts, the front end plate fits against the front side surface of the forming die base. The support base moves away from the forming die base, and directly below the cylindrical cavity is the workbench.

[0017] Furthermore, the height of the sealing plate body is the same as the height of the upper opening, and the height of the cushion base is less than the height of the sealing plate body.

[0018] The utility model has the following beneficial effects:

[0019] 1. By designing a novel die structure and arranging a slidable support base, after the support base is in place, the cushion base is concentrically arranged directly below the cylindrical cavity, which can form a complete forming cavity for the stable stamping forming of bolts. After the support base is removed, the slag inside the forming cavity can be quickly discharged, ensuring the forming effect and quality of the bolts.

[0020] 2. The support base designed in the utility model has a horizontal sliding movement track. The upper surface and the lower surface of the support base respectively fit against the forming die base and the workbench, which can ensure the support ability and position stability of the support base, and the impact force will not impact the oil cylinder, ensuring the forming effect.

[0021] 3. Through the design of a detachable cushion base and mounting seat, the cushion base can be quickly replaced according to bolts with different length requirements. Moreover, the sealing plate body and the cushion base can be removed from the forming die through the upper opening, providing a large operating space, facilitating the operation of the staff, and greatly improving the applicable range of the die.

[0022] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
