technical field

The utility model relates to the technical field of fastener production, in particular to a punch material pushing device used for the production of extra-long bolts.

Background technique

The production of the existing extra-long bolts (length 50-200mm) usually uses the connecting rod of the punch to push the material. Because the height of the punch frame is fixed, the length of the bolts produced is limited, and in the production process, there are often The phenomenon of the top bending of the connecting rod not only reduces the production efficiency but also brings certain risk factors.

Utility model content

The purpose of the present utility model is to provide a material pushing device for a punch press to solve the problems encountered in the above-mentioned background technology.

For achieving the above object, the technical scheme of the present invention is as follows:

A material pushing device for a punch, comprising a push block, a fixed block, a guide die and a hydraulic oil cylinder. The push block is a trapezoidal structure with sliding surfaces on both sides, and a connecting rod is provided at the rear of the push block. The block is arranged on both sides of the push block and is slidably connected with the push block. The inner side of the fixed block is provided with a chute that matches the sliding surface. The guide mold is fixed on the top of the push block, and the middle of the guide mold is vertical. A circular guide hole is directly opened, the guide hole penetrates the inside of the push block, the hydraulic cylinder is arranged on one side of the push block, and the end of the push rod of the hydraulic cylinder is fixedly connected with the connecting rod.

In the above solution, the sliding surface and the chute are both smooth inclined surfaces.

In the above solution, the guide die is cylindrical.

In the above solution, the interior of the fixing block is evenly provided with mounting holes.

In the above solution, the mounting holes are bolt fixing grooves.

Compared with the prior art, the beneficial effect of the present invention is that a circular guide hole is vertically opened in the middle of the guide die for placing materials such as extra-long bolts, and the vertical guide hole can also be used for punching. The connecting rod plays a guiding role in the stamping process, which can better stamp and forge the material without causing the top bending of the connecting rod. During the punching process, the push block at the bottom can be driven by the hydraulic cylinder to slide back and forth between the two fixed blocks, which is convenient for placing the material and then pulling it back to the punching working position of the connecting rod of the punch. Therefore, it can punch materials such as special long bolts.

Detailed ways

The technical solutions of the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1 and Figure 2, a punch material pushing device includes a push block 1, a fixed block 2, a guide die 3 and a hydraulic cylinder 4. The push block 1 is a trapezoid structure with sliding surfaces 11 on both sides. The rear of the block 1 is provided with a connecting rod 12 . The fixed block 2 is arranged on both sides of the push block 1 and is slidably connected with the push block 1 . Both the sliding surface 11 and the sliding groove 21 are smooth inclined surfaces, which is convenient for manufacturing and low in production cost, and the sliding effect is higher than that of other concave-convex sliders.

Installation holes 22 are evenly opened in the interior of the fixed block 2, and the installation holes 22 are bolt fixing grooves, which are used to fix the fixed block 2 on both sides of the punching connecting rod table of the punch press by bolts, and also push the material for the installation push block 1. Provides sliding working conditions.

The guide die 3 is cylindrical, the guide die 3 is fixed on the top of the push block 1, and a circular guide hole 31 is vertically opened in the middle of the guide die 3. The guide hole 31 is used for placing extra long bolts, and the guide hole 31 can also be The connecting rod of the punch press plays a guiding role in the stamping process, which can better stamp and forge the material without causing the top bending of the connecting rod. The guide hole 31 runs through the inside of the push block 1 and is used to increase the overall height of the device after the extra-long bolt is installed.

The hydraulic cylinder 4 is arranged on one side of the push block 1 and is connected to the power supply of the machine tool through a switch. The hydraulic cylinder 4 can be of type PY497, which is fixed at the back of the workbench of the punch press during implementation. Because the end of the push rod of the hydraulic cylinder 4 is fixedly connected with the connecting rod 12, the hydraulic cylinder 4 pushes the push block 1 out during the pushing process. The push rod of the hydraulic cylinder 4 pulls out the push block 1 during the retraction process, so as to push the material in the guide hole 31 in the middle of the push block 1 .

During the implementation, in order to facilitate the timely opening of the hydraulic cylinder 4 to control the push block 1 to push materials in and out, the hydraulic cylinder 4 can be connected to the hydraulic system in the punch press, and the hydraulic cylinder 4 and the hoist can be driven to work together through the same hydraulic base station. , realizing the semi-automation of the production of extra-long bolts, greatly reducing labor costs and improving work efficiency.

In the present invention, a circular guide hole 31 is vertically opened in the middle of the guide die 3 for placing materials such as extra-long bolts, and the vertical guide hole 31 can also guide the connecting rod of the punch press during the punching process. , Better stamping and forging of materials. During the punching process, the push block 1 at the bottom can be driven by the hydraulic cylinder 4 to slide back and forth between the two fixed blocks 2, which is convenient for placing the material and then pulling it back to the punching working position of the connecting rod of the punching machine. Long material products, so it can punch special long bolts and other materials.
